Summarize the latest questions and answers about nucleic acid detection, home isolation, etc., and the joint prevention and control mechanism in the State Council.

On December 8th, the State Council Joint Prevention and Control Mechanism held a press conference to introduce the situation of further optimizing the implementation of epidemic prevention and control measures and answer media questions.

Graded and classified treatment

How do medical institutions do a good job in graded and classified treatment of key populations?

Guo Yanhong, director of the Medical Emergency Department of the National Health and Wellness Commission, said that in order to make overall plans for the layout and utilization of medical resources, the key point is to do a good job in the medical treatment and management of those who are seriously ill and have serious risk factors in COVID-19, and we have classified and treated those infected with COVID-19 virus.

First, for mild and asymptomatic infected people, those who have no basic diseases or whose basic diseases are in a stable period, they can take care of themselves at home.

Second, this part of patients with severe illness or serious risk should be admitted to designated hospitals. In order to ensure the treatment of this part of patients with severe illness or serious risk, we require that hospitals with strong comprehensive ability and high treatment level should be selected as designated treatment hospitals, and at the same time, they should be equipped with strong medical staff.

Thirdly, there are still some patients who have basic diseases or are mainly suffering from other diseases and go to general hospitals or specialized hospitals for treatment. In the process of treatment, they may be COVID-19-positive after testing. For these people, we have asked general hospitals and specialized hospitals to set up buffer zones, whether in outpatient, emergency or inpatient areas, so as to ensure that these patients can be treated and meet the needs of people’s medical services.

What kind of symptoms do you need to see a doctor in a medical institution?

Wang Guiqiang, director of infectious diseases department of Peking University First Hospital, said that if the following five situations occur, it is recommended to contact community doctors. If the illness is serious, you can contact 120 to go to the hospital for diagnosis and treatment.

The first situation is dyspnea or shortness of breath.

The second situation is that after drug treatment, you still have a fever. If it exceeds 38.5 degrees Celsius for more than 3 days, you should go to the hospital.

The third situation is that the original underlying diseases are obviously aggravated. For example, when the medication for hypertension is uncontrollable, the medication for diabetes is uncontrollable or there are other critical risks, you must go to the hospital for treatment in time.

The fourth situation is that children have some drowsiness, refusal to eat, diarrhea, vomiting, etc., which will not be relieved after treatment, and they will have to go to the hospital for treatment for more than two days.

The fifth is that pregnant women have headaches, dizziness, palpitation, shortness of breath or abnormal fetal movement, etc., and they should also go to the hospital for further diagnosis and treatment. Read the original > > >

nucleic acid testing

From what aspects has the scope and frequency of nucleic acid detection been reduced?

He Qinghua, a first-class inspector, said that further optimization measures require further optimization of nucleic acid detection, emphasizing that nucleic acid detection should focus on areas and personnel with high risk of infection, mainly reducing the scope and frequency of nucleic acid detection from the following aspects:

First, not to carry out all-staff nucleic acid testing according to administrative regions.

Second, except for special places such as nursing homes, welfare homes, medical institutions, child care institutions, primary and secondary schools, negative proof of nucleic acid testing is not required.

Third, cross-regional migrants will no longer be examined for negative nucleic acid test certificates or health codes, and landing inspections will no longer be carried out.

Fourth, according to the needs of epidemic prevention work, antigen testing can be carried out.

In addition, it is also required to carry out nucleic acid testing for employees in high-risk positions in accordance with the relevant provisions of Article 20 optimization measures, and the scope of nucleic acid testing shall not be expanded.

Employees in high-risk positions mainly include:

What are the special places that need to provide negative nucleic acid certificates and health codes?

He Qinghua, the first-class inspector of the Department of Transmission and Prevention of the National Bureau of Disease Control and Prevention, said that although the pathogenicity of the mutant strains in Omicron is obviously weakened, the risk of serious illness is higher for the elderly and key people with basic diseases, especially those who live in nursing homes and welfare homes, as well as places where special people are concentrated, such places are prone to cluster epidemics once the source of infection is introduced, so it is necessary to provide negative proof of nucleic acid testing for foreigners entering these special places. People who enter other general places, including those who take public transport and cross-regional migrants, do not need to provide negative proof of nucleic acid test, nor do they need to carry out landing inspection, but they should do personal protection, wear masks regularly, and reduce gathering and interpersonal contact. The new 10 measures also suggest that large enterprises and some specific places can determine some prevention and control measures by themselves, and all localities can take targeted measures according to the local epidemic situation. At the same time, it is mentioned in the 20 measures that "one enterprise, one policy" and "one park, one policy" can be adopted for the prevention and control of some key enterprises, and the new 10 measures are a further continuation and update of the 20 measures.

How often do employees in high-risk positions need to carry out nucleic acid testing?

Wang Liping, a researcher at the Center for Disease Control and Prevention of China, said that according to the ninth edition of the prevention and control plan and 20 optimization measures, the employees in high-risk positions are mainly divided into two categories:

The first category is extremely risky, which refers to the entry personnel, goods, people in direct contact with the environment, staff in centralized isolation places, medical staff in designated medical institutions and fever clinics in general medical institutions,They are required to conduct closed-loop management during the operation and conduct nucleic acid testing every day;

The second category refers to some employees who are closely related to residents’ lives, such as Shangchao, Express Delivery, Takeaway, etc., who have intensive working environment, frequent contacts and strong mobility. For such people, we should also do a good job in monitoring and nucleic acid testing.Nucleic acid testing is required twice a week.

home quarantine

What factors should people consider when choosing home isolation and centralized isolation?

Wang Guiqiang, director of the Department of Infectious Diseases of the First Hospital of Peking University, said that close contacts need some basic conditions to choose home isolation: it is best to have a separate room and good ventilation; If you share the bathroom, you should do a good disinfection treatment; If the family stays at home independently, they should be able to take care of themselves in life; People at home must stay indoors and refuse all kinds of visits. In this case, we still suggest that close contact with people can be isolated at home.

We emphasize that when we are isolated at home, if there are elderly people, infants and so on who need to be taken care of at home, then we should pay attention to personal protection to avoid potential transmission risks, and we should wear masks and do a good job of hand hygiene. At the same time, antigen testing should be carried out every day, and once it is positive, it should be reported in time. At the same time, do self-monitoring after being positive. When it is negative, you should also do a good job of daily self-symptom monitoring, including whether you have fever, cough and shortness of breath. If these manifestations appear, you should also report them to the community in time.

The elderly, pregnant women, infants and people suffering from basic diseases such as cardiovascular diseases must report to the community in time for special needs, including medication and treatment, when observing at home. In case of emergency, they should also seek medical treatment in time.

How to do personal protection for isolated people at home?

Wang Guiqiang, director of the Infectious Diseases Department of the First Hospital of Peking University, said that it is necessary to do a good job of personal protection for isolated people at home, and keep as little contact with family members as possible, and keep a certain distance if they contact. Include the following points that we emphasize:

First, the living room should be ventilated every day, and good ventilation is very important to reduce the spread of respiratory infectious diseases.

Second, the bathroom, bathroom, if it is best to use it alone, it should be disinfected every day. If it is shared, it must be staggered, and it should be disinfected well after use to avoid family transmission.

Third, do a good job in hand hygiene and environmental disinfection, including paying attention to hand hygiene during cooking and dining.

Fourth, when coughing or sneezing, be sure to cover it with a paper towel and throw it into the trash can to avoid the potential risk of aerosol transmission caused by splashing.

Fifth, used paper towels, masks, disposable gloves and other household garbage are put into plastic bags and placed in special trash cans.

Another thing we should pay attention to is that personal items should not be mixed and separated from family members as much as possible, because the items themselves may also pose the risk of virus transmission.

If the medical staff are infected with Covid-19, will they be treated at home or continue to work?

Guo Yanhong, director of the Medical Emergency Department of the National Health and Wellness Commission, said that medical staff is a very special group. Due to their special positions, they will receive a large number of patients every day, so they face the highest risk of infection and the work is very heavy. It can be said that occupational exposure is inevitable.Once medical personnel are infected with Covid-19, they should also follow the relevant requirements of the "New Ten Articles".However, in order to minimize the occupational exposure risk of medical staff, we put forward a series of requirements for the management of medical institutions.

Sealing and control measures

Units and buildings with "mixed pipe positive" detected no longer need to be sealed?

Wang Liping, a researcher at the Transmission and Prevention Department of China CDC, said that when the mixed tube is found to be positive, the relevant departments will inform the mixed inspection personnel as soon as possible, so that they can implement the local isolation measures, and at the same time, they will arrange personnel to take samples at home for review as soon as possible.Therefore, people in the same building and unit as those who are positive for mixed inspection do not need to be temporarily blocked.

When the recheck results are all negative, the mixed inspection personnel will immediately remove the isolation measures. However, if the door-to-door recheck results are positive, the control measures should be implemented in time, and the close contact should be controlled in time according to the results of field investigation and risk judgment, the risk area should be delineated, and the relevant epidemic situation should be handled well. Read the original > > >

Can only one positive infected person be detected without delineating high-risk areas?

Wang Liping, a researcher at the Center for Disease Control and Prevention of China,For the case that only one case is detectedIf the risk of communication in his work place, residence and activity place is relatively low, and after the secret connection is controlled in time, there is no risk of community communication after judgment, at this time, it is not necessary to delimit high-risk areas.

For a large number of households, a unit or a building may have hundreds of households.According to the current situation and risk judgment, according to the new ten articles, only the floors or households with high exposure risk can be judged to minimize the inconvenience caused by the epidemic to people’s lives.

After the high-risk area is demarcated, if no new infections are detected for five consecutive days, the seal can be released in time to avoid long-term seal control.. The new article 10 also mentioned that people with asymptomatic infection, mild illness or even close contact can choose home isolation. Therefore, it is very likely that there are some people in the community who are sealed off. For the newly infected people who are detected in the high-risk area after the risk area has been sealed off, if they live with the positive people who are strictly quarantined at home or are close to each other, there is no risk of community transmission outside the home after the judgment. In this case, even if they are positive, it will not affect the time to unseal the whole high-risk area, and they will still be unsealed without new ones for five consecutive days.

Vaccination for the elderly

Why do the elderly need vaccination?

Xia Gang, Director of the Department of Health and Immunization, said that the current epidemic situation is still severe and complicated, and vaccination still has good effects in preventing severe illness and death. Vulnerable people such as the elderly can easily develop into severe illness, critical illness and even death after being infected with Covid-19, and vaccination with COVID-19 vaccine will benefit the most. There are quite a few disabled and semi-disabled elderly people in China who live at home for a long time and rarely go out. However, they may still be infected during the company or visit of relatives, which may lead to illness or even serious illness and death. Therefore, it is still necessary to vaccinate.

According to Xia Gang, according to research, compared with young people, the risk of serious illness after COVID-19 infection is 5 times, 7 times and 9 times respectively, and the risk of death is 90 times, 220 times and 570 times respectively. If the elderly over 80 years old are not vaccinated with one dose, their risk of death is about 14.7%; If one dose of vaccine is inoculated, the risk of death will be reduced to 7.16%; If three doses of vaccine are inoculated, the risk of death will be reduced to 1.5%. Compared with no vaccination, the risk of death decreased by 9.3 times after vaccination with 3 doses. Read the original > > >

What services and conveniences will be provided for the elderly when they are vaccinated?

Xia Gang introduced that in view of the mobility of these elderly people, in order to enable them to vaccinate more conveniently, we have continued some previous good practices, including using mobile vaccination vehicles, opening special vaccination sessions for the elderly and opening green channels for vaccination for the elderly. At the same time, it is also suggested that all localities can send medical personnel with rich experience in diagnosis, treatment and vaccination to form vaccination teams, carry common equipment and medicines needed during observation after vaccination, and provide home vaccination services for disabled and semi-disabled elderly people, so that these elderly people can complete vaccination without leaving home.

Baidu antigen-antibody structure prediction model is far more effective than AlphaFold3.

According to Baidu AI, in the research and development of antibody drugs and polypeptide drugs, the prediction of antigen-antibody and polypeptide protein complex structure plays a vital guiding role, and its accuracy is very important for subsequent research. However, from the current calculation methods, whether it is the energy function tool based on physical method or the method based on deep neural network, including the recently updated AlphaFold 3 of DeepMind, there is still much room for improvement in the structural prediction accuracy of antigen-antibody and protein-polypeptide complexes. In response to this challenge, PaddleHelix team of Baidu propeller developed HelixFold-Multimer model. By optimizing data, network structure and training methods, it has reached the leading position in the industry in predicting the structure of antigen-antibody/polypeptide protein complex. Compared with the existing methods, HelixFold-Multimer is far superior to similar methods, including the newly released AlphaFold 3, in two core key indicators: DockQ and success rate.

Research: ferrets and cats are susceptible to Covid-19, which can cause "cat-to-cat transmission"

  Covid-19 is thought to originate from bats, and it is 96.2% similar to RaTG13 (collected by Shi Zhengli, Wuhan Institute of Virology, Chinese Academy of Sciences, in Yunnan, China in 2013) in nucleotide sequence level. However, it is a kind of novel coronavirus that has not been detected in humans and other animals before, and its appearance has brought many new problems to be solved urgently, including whether other pets, livestock and poultry may be infected by Covid-19 besides humans?

  On April 8th, local time, the top academic journal Science published the paper "Susceptibility of Ferrets, Cats, Dogs, and Different Domestic Animals to SARS-coronavirus-2" online. The purpose of this study is to find out some questions: Will Covid-19 be transmitted to other animal species, thus becoming a "reservoir" of infection? Covid-19 infection has many clinical manifestations in humans, ranging from mild infection to death, so how is it manifested in other animals? With the development of vaccines and antiviral drugs, which animals can be used to simulate the effects of these drugs or vaccines on humans most accurately?

  In order to solve these problems, research teams from the State Key Laboratory of Veterinary Biotechnology of Harbin Veterinary Research Institute of Chinese Academy of Agricultural Sciences and the National High-level Biosafety Laboratory of Animal Disease Prevention and Control evaluated the susceptibility of different model experimental animals, pets and livestock to Covid-19, infected Covid-19 through experiments, observed the clinical manifestations and pathological changes of vaccinated animals and cohabiting animals, and detected the viral load of organs and tissues, the emission of respiratory and intestinal viruses, and the seroconversion of antibodies against Covid-19 in animals.

  Their research shows that Covid-19 has weak replication ability in dogs, pigs, chickens and ducks, but it can replicate efficiently in ferrets’ upper respiratory tract and cats’ respiratory system and digestive system. Experimental infected cats can spread Covid-19 through the air; Some cats can cause serious illness or even death after infection, and the illness of young cats is obviously more serious than that of older cats.

  Histopathological observation confirmed that virus infection in cats can cause lung inflammation and intestinal mucosal damage to varying degrees. Immunohistochemical study showed that there were a large number of virus infections in mucosal epithelium and olfactory bulb cells of upper respiratory tract (nasal cavity, maxilla, tonsil), mucous gland epithelial cells of trachea and bronchial mucosa, and intestinal mucosal epithelium.

  The correspondent of this paper is Chen Hualan, academician of China Academy of Sciences, chief scientist of the innovation team of animal influenza basic and prevention research in Harbin Veterinary Research Institute of China Academy of Agricultural Sciences, Bu Zhigao, director of Harbin Veterinary Research Institute of Chinese Academy of Agricultural Sciences and director of the national high-level biosafety laboratory for animal disease prevention and control, and Wu Guizhen, secretary of the Party Committee of Institute of Viral Disease Prevention and Control of China CDC and director of BSL-3 laboratory. Previously, on March 31st, local time, the research team had taken the lead in publishing the research on the preprint platform bioRxiv.

  It is worth mentioning that the National High-level Biosafety Laboratory for Animal Disease Prevention and Control is one of the existing two P4 laboratories in China, and the other is in Wuhan National Biosafety Laboratory of Chinese Academy of Sciences. All the experiments of Covid-19 infection in this study were carried out in P4 laboratory, which was approved by the Ministry of Agriculture and Rural Affairs of China. Animal research and animal welfare programs were approved by the Animal Experimental Ethics Committee of China Academy of Agricultural Sciences.

  According to the press release issued by official website, Harbin Veterinary Research Institute of Chinese Academy of Agricultural Sciences, different coronaviruses have been prevalent in mammals and poultry, but most of these coronaviruses are limited to specific species of animals and generally cannot infect humans. Similarly, several common coronaviruses in humans do not infect other animals. However, some coronaviruses from bats, such as SARS and MERS virus, can often infect many animals and humans.

  At present, Covid-19 is popular among a wide range of people in the world, and the risk of introducing animals in close contact with human beings is increasing. Therefore, it is urgent to study the susceptibility of domestic animals in close contact with human beings to Covid-19, evaluate whether domestic animals are exposed to Covid-19 hazards and become potential intermediate hosts, and provide scientific basis for prevention and control of Covid-19.

  In addition, in view of the current global epidemic situation of COVID-19, it is very likely that it will evolve into a common infectious disease, and it is urgent to establish a stable and reliable animal infection model to meet the needs of vaccine and drug research and development evaluation.

  The research team stressed that the monitoring of cat COVID-19 should be regarded as an auxiliary means to eliminate the current Covid-19 epidemic. They called for close monitoring and protection of cats in epidemic areas, avoiding their contact with infectious sources and preventing them from becoming possible transmission hosts or storage hosts.

  In addition, it was previously questioned that cats infected with COVID-19 were caused by large doses under laboratory conditions. However, in addition to this research, on April 3rd, Academician Jin Meilin, professor of the State Key Laboratory of Agricultural Microbiology of Huazhong Agricultural University, director of the Key Laboratory of Veterinary Diagnostic Preparations of the Ministry of Agriculture, director of the Research Center for Emerging Infectious Diseases of Wuhan Institute of Virology, Chinese Academy of Sciences, and researcher Shi Zhengli, director of the Key Laboratory of Highly Pathogenic Biology and Biosafety of Chinese Academy of Sciences, also published a study on the preprint platform bioRxiv. Through the investigation of cat serum, they found that the serum ELISA test of 102 cats collected after the outbreak of COVID-19 in Wuhan showed that the serum from 15 cats (14.7%) was positive for Covid-19 receptor binding domain (RBD).

  Nadia, a 4-year-old tiger from Bronx Zoo in new york, USA, was recently diagnosed with Covid-19. On April 5, local time, the US Department of Agriculture issued a statement confirming that a tiger in a zoo in new york was diagnosed with Covid-19, and several other lions and tigers also showed symptoms of respiratory diseases. Officials at the Bronx Zoo in new york said that nadia, three other tigers and three African lions had symptoms of dry cough and loss of appetite, but they are expected to recover. Public health officials believe that these animals were infected by an asymptomatic employee.

  Covid-19 can be replicated in the upper respiratory tract of ferrets for up to 8 days, but it will not cause serious illness or death.

  Ferrets are often used as animal models of human respiratory viruses. Therefore, the research team first tested ferrets’ sensitivity to Covid-19.

  Two Covid-19 strains were used in this study: F13-E from Wuhan South China Seafood Market and CTan-H from a patient infected with Covid-19.

  The research team inoculated 10 5 PFU (Plaque Forming Unit) F13-E or CTan-H into ferrets through nose respectively, and euthanized them on the 4th day after inoculation (P.I.). The turbinate, soft palate, tonsil, trachea, lung, heart, spleen, kidney, pancreas, small intestine, brain and liver of each ferret were collected, and the viral RNA was determined by qPCR and virus titration.

  Viral RNA:A in ferrets’ organs or tissues: A, F13-E, B, CTAN-H..

  The results showed that viral RNA and infectious virus were detected in the turbinate, soft palate and tonsil of all four ferrets, but not in other tissues.

  C, virus titer in organs or tissues of ferrets inoculated with F13-E, D and CTAN-H.

  The research team believes that these results show that Covid-19 can replicate in the upper respiratory tract of ferrets, but it has not been detected in other tissues.

  In order to study the replication dynamics of virus in ferrets, the research team intranasally inoculated 6 ferrets with 10^5pfu of F13-E(3) or CTan-H(3), and then placed them in three isolated cages. On the 2nd, 4th, 6th, 8th and 10th day, ferret nasal wash and rectal swab were collected for virus RNA detection and virus titration. At the same time, their body temperature and COVID-19 signs were monitored for two weeks.

  Viral RNA in the nasal wash of ferrets inoculated with F13-E(E) and CTan-H(F). Viral titers in the nasal wash of ferrets inoculated with F13-E(G) and CTan-H(H).

  The results showed that viral RNA was found in the nasal wash of all six ferrets on the 2nd, 4th, 6th and 8th day. Viral RNA was also found in some rectal swabs, but the copy number was significantly lower than that of nasal wash. Infectious virus was detected in nasal wash of all ferrets, but none of them was found in rectal swab.

  One ferret in each group developed fever and loss of appetite on the 10th and 12th days respectively. In order to investigate whether these symptoms are caused by virus replication in the lower respiratory tract, the research team euthanized the two ferrets on the 13th day and collected their organs for virus RNA detection.

  However, except for the ferret turbinate inoculated with CTan-H, the low copy number was detected, and no viral RNA was detected in any other tissues or organs.

  Pathological studies showed that two ferrets euthanized on the 13th day had severe lymphoplasmacytic vasculitis and vasculitis, the number of type II alveolar cells, macrophages and neutrophils in alveolar septa and alveolar cavities increased, and the lungs had mild bronchiolitis.

  The asterisk indicates that the animals were euthanized on the 13th day after inoculation, and the other four animals were euthanized on the 20th day.

  Covid-19 antibody was detected in all ferrets by ELISA and neutralization test, and the antibody titers of two ferrets euthanized on the 13th day were significantly lower than those euthanized on the 20th day.

  In order to further study whether Covid-19 was replicated in ferrets’ lungs, the research team inoculated 8 ferrets with 10^5 pfu of CTan-H through trachea, and euthanized 2 animals on the 2nd, 4th, 8th and 14th days, respectively, and detected virus RNA in tissues and organs.

  Among the two ferrets euthanized on the second day and the two ferrets euthanized on the fourth day, the researchers only detected viral RNA; in the turbinate and soft palate of one of them. Among the two ferrets euthanized on the eighth day, viral RNA; was detected in the soft palate of one ferret and in the turbinate, soft palate, tonsil and trachea of the other ferret. No viral RNA was detected in the two ferrets euthanized on the 14th day.

  These results indicate that Covid-19 can replicate in the upper respiratory tract of ferrets for up to 8 days without causing serious illness or death.

  At the end of the paper, the research team also mentioned that, comparatively speaking, Covid-19 is different from other influenza viruses that can replicate in the upper respiratory tract and lower respiratory tract of ferrets, and even human SARS-CoV. Covid-19 is only replicated in ferrets’ nasal bones, soft palate and tonsils. It can also replicate in the digestive tract, but even if the virus is inoculated in the trachea, the virus is still not detected in the lungs of ferrets.

  Cats are highly susceptible to "cat-to-cat transmission": the monitoring of cat Covid-19 should be regarded as an auxiliary means of epidemic prevention and control.

  It is worth noting that cats and dogs are in close contact with humans, so the research team thinks that besides laboratory animals like ferrets, it is very important to know the susceptibility of domestic animals that often live with humans to COVID-19 for the control of Covid-19.

  The research team first studied the replication of Covid-19 in cats. Five 8-month-old subadult domestic cats (inbred lines) were intranasally inoculated with 10^5pfu of CTan-H, and two of them were scheduled to be euthanized on the sixth day to evaluate the virus replication in their organs. Three cats were put in separate cages in the isolator. In order to monitor the spread of respiratory droplets, an uninfected cat was placed in a cage adjacent to each cat vaccinated with the virus.

  Because 8-month-old cats are aggressive, it is difficult to carry out routine nasal cleaning on them. In order to avoid possible harm, the research team collected the feces of these cats and checked the viral RNA in their organs after euthanasia.

  Virus RNA was detected in the nasal bone, soft palate and tonsils of two sub-adult domestic cats euthanized on the 6th day, and virus RNA was also detected in the trachea of one cat and the small intestine of the other cat. However, no viral RNA was detected in any lung samples of these two cats.

  Infectious viruses were detected in the nasal bones, soft palate, tonsils and trachea of these cats, but no infectious viruses were found in the small intestine with positive viral RNA.

  The spread of Covid-19 among cats.

  In the study of virus transmission, RNA virus was detected in the feces of two vaccinated cats on the third day, and RNA virus was detected in the feces of all three vaccinated cats on the fifth day. Among the three cats at risk of virus exposure, viral RNA was detected in the feces of one cat on the third day.

  Virus-infected cats with positive feces were euthanized on the 11th day. Virus RNA was detected in the soft palate and tonsils of the infected cats and in the nasal bones, soft palate, tonsils and trachea of the exposed cats, indicating that respiratory droplets spread between cats.

  On the 12th day, the research team euthanized the remaining cats. Viral RNA was detected in the tonsils of one virus-infected cat and the nasal bone, soft palate, tonsils and trachea of another virus-infected cat, but it was not detected in any organ or tissue of the two virus-exposed cats.

  Through ELISA and neutralization test, Covid-19 antibody was detected in all three cats inoculated with virus and one cat exposed to virus.

  Covid-19 replicates efficiently in respiratory system and digestive system of infected cats, causing pathological damage and inflammatory reaction. Histopathological and immunohistochemical study on cats that died or were euthanized three days after virus infection. (a) The arrangement of nasal mucosa epithelium is disordered, cilia fall off (arrow), and lymphocytes in lamina propria infiltrate (arrow). (b) The tonsil epithelial cells are degenerated and necrotic, and the surface of mucosal epithelium (asterisk) is covered with cell fragments and neutrophils (arrow). (c) Epithelial degeneration and necrosis of tracheal mucosa (arrow), with mucus (asterisk) mixed with a large number of cell fragments on the surface. (d) Epithelial necrosis of tracheal mucous glands and infiltration of lymphocytes (arrow). (e) Normal lung tissue structure of uninfected cats. (f) Aggregation of inflammatory cells in pulmonary blood vessels and coagulation of fibrin (arrow). (g) A large number of macrophages and lymphocytes infiltrated in alveoli, that is, alveolar septa. (h) Infiltration and proliferation of alveoli and alveolar septitis. (i) Some cells in the epithelium of small intestine are degenerated and necrotic, and lymphocytes in the lamina propria are moderately infiltrated (arrow). (j) A large number of epithelial cells of turbinate mucosa were positive for virus antigen (brown). (k) A large number of exfoliated cells in tonsil mucosa epithelium and mucosa surface were positive for virus antigen (brown). (l) A large number of virus antigens were positive (brown) in serous cells of tracheal mucous glands. (m) A large number of small intestinal mucosal epithelial cells were positive for virus antigen (brown). Ruler line A, I = 100 μ m, B-H, J-L = 200 μ m, M = 500 μ m

  The research team also repeated the above-mentioned replication and transmission research in sub-adult cats in young cats (70-100 days). Histopathological studies on the samples of young cats who died or were euthanized on the third day after being inoculated with the virus showed that the nasal cavity and tracheal mucosa epithelium and lungs of the two cats had a lot of damage.

  These results indicate that Covid-19 can be effectively replicated in cats, and young cats are more susceptible to infection. More importantly, the virus can spread from cat to cat through respiratory droplets.

  Next, the research team also studied the replication and spread of Covid-19 in dogs, and the results showed that dogs were less sensitive to Covid-19. Similar studies also show that pigs, chickens and ducks are not sensitive to Covid-19.

  Overall, the research team found that ferrets and cats are highly sensitive to Covid-19, dogs are less sensitive, and domestic animals including pigs, chickens and ducks are not sensitive to the virus.

  In addition, it is reported that Covid-19 uses angiotensin-converting enzyme 2 (ACE2) as its receptor to enter cells, and ACE2 is mainly expressed in type II lung cells and serous epithelial cells of ferrets’ tracheal-bronchial submucosal glands. Therefore, the research team believes that the potential mechanism to prevent Covid-19 from replicating in ferrets’ lower respiratory tract remains to be studied.

  The results of this study show that ferrets can be used as animal models for vaccine and drug evaluation in Covid-19. Dogs, pigs, chickens and ducks are not susceptible to Covid-19, which has important guiding significance for the traceability of virus hosts; More importantly, cats are highly susceptible to Covid-19.

  The research team called for close monitoring and protection of cats in epidemic areas to avoid contact with infectious sources and prevent them from becoming possible transmission hosts or storage hosts. The monitoring of cat COVID-19 should be regarded as an auxiliary means to eliminate the current Covid-19 epidemic.

Ministry of Environmental Protection: The quality of water environment in China is generally good, and some tributaries are seriously polluted.

  BEIJING, Nov. 18 (Xinhua)-Zhao Yingmin, vice minister of the Ministry of Environmental Protection, said on the 18th that the water environment quality in China is generally improving, but the situation is still grim, with widespread ecological destruction in river basins, non-point source pollution not effectively curbed, serious pollution in some tributaries, prominent eutrophication in some lakes, water environment carrying capacity reaching or approaching the upper limit, and "black odor" problems in many rivers and ditches flowing through towns. However, there is no contradiction between the overall improvement of the country and the local deterioration.

  The the State Council Press Office held a routine briefing on the State Council policy today to introduce the policies related to the "Thirteenth Five-Year Plan" for eco-environment. For the reporter’s "‘ Water Ten Articles ’ Zhao Yingmin answered questions such as the progress made in one year’s implementation, what problems exist in water pollution prevention and control, and the focus of the next step.

  Zhao Yingmin introduced that "Water Ten Articles" was released in 2015, and this year is the first implementation year, which has made great progress. Over the past year, there have been six main developments: First, according to the requirements of the "Water Ten Articles", the Ministry of Environmental Protection and 31 provinces (autonomous regions and municipalities) signed a responsibility letter for water pollution prevention and control, which decomposed the quality improvement tasks required by the "Water Ten Articles" into provinces one by one, and also required the provinces to decompose them into cities one by one, and finally implemented them in 1940 control units across the country. Each unit has clear and specific environmental quality for each year. At the same time, the Ministry of Environmental Protection has also established a national water pollution prevention and control mechanism, which has promoted the establishment of a linkage and cooperation mechanism for water pollution prevention and control in Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta regions.

  The second is to organize the compilation of water pollution prevention and control plans for key river basins, prevent and control water pollution in the whole process, promote water resources conservation and recycling, and strengthen ecological protection and restoration.

  The third is to organize investigation and evaluation of the environmental protection status of more than 900 centralized drinking water sources in cities at prefecture level and above, and guide all localities to speed up the standardized construction of drinking water sources. This includes the delineation of drinking water source protection areas, and cleaning up illegal buildings and sewage outlets in the protection areas according to law.

  Fourth, according to the requirements of water quality improvement, decompose and implement the targets and requirements for emission reduction of major water pollutants in the 13 th Five-Year Plan and 2016.

  The fifth is to implement the task of comprehensively improving the environment of 130,000 newly established villages by 2020, implement the central rural energy conservation and emission reduction funds in 2016, and support all localities to continue to comprehensively improve the rural environment.

  Sixth, a series of relevant technical documents have been issued to guide the implementation of the "Water Ten Articles" in various places, including the Technical Guide for the Preparation of Water Body Standards, and a series of other technical documents.

  At present, this year is 1-mdash; Of the 1,922 monitoring sections with monitoring data in September, 1,351 were above Grade III, accounting for 70.3%, up 4.0 percentage points year-on-year. At the same time, it should also be noted that 166 are inferior to category V, accounting for 8.6% of the total, a year-on-year decrease of 1.2 percentage points. At present, we estimate that this year, as the first complete year of the implementation of the "Water Ten Articles", it should be said that it has achieved a good start, and the annual target set by the "Water Ten Articles" is expected to be completed on the whole.

  Ying Zhao residents further pointed out that although the quality of water environment has been continuously improved through the efforts of the Twelfth Five-Year Plan, there is still a big gap compared with the people’s growing environmental demand. The prevention and control of water pollution is unbalanced, and the phenomenon of ecological destruction in river basins is still relatively common at present. It should be said that non-point source pollution has not been effectively curbed, some tributaries are seriously polluted, some lakes are eutrophic, the carrying capacity of water environment has reached or approached the upper limit, and many rivers and ditches flowing through towns are "black and smelly", which has been strongly reflected by the masses.

  Zhao Yingmin also introduced three characteristics of the national water environment. First, the surface water quality is generally stable and getting better, but some water pollution problems are outstanding. Second, the situation of good water protection is grim. Third, the main pollution factors have differentiated. In the 12th Five-Year Plan, the binding index COD has declined, but the nitrogen and phosphorus are changing. Because the chemical oxygen demand has dropped a lot, relatively speaking, the pollutants that were originally in the second and third places have gradually become prominent pollution problems in some waters.

  He said that the "Thirteenth Five-Year Plan" clearly put forward the goal and overall thinking by 2020. In the next step, the Ministry of Environmental Protection will insist on improving the quality of water environment as the core, take the implementation of the "Ten Water Articles" as the starting point, and conscientiously implement the tasks specified in the "Thirteenth Five-Year Plan". First, adhere to the problem orientation and solve the outstanding water pollution problem that the masses are most concerned about and strongly reflect. "1+2" work priorities. "1" is to pay close attention to the safety of drinking water. "2" starts from both good water and poor water. The so-called good water is a class III or above water body that has not been polluted at present, and protection should be strengthened; Poor water is the so-called "black and smelly" water body, which is inferior to Class V water body, and we should also pay close attention to treatment. The second is to do a good job in source prevention and strictly observe the red line of total space access. The third is to highlight key areas and strengthen governance measures. The fourth is to innovate management methods and improve the management ability of water environment quality. The fifth is to strictly implement the responsibilities of local and enterprises.

  Ying Zhao residents further indicated that the water environment quality in China is improving year by year. It should be said that the improvement of environmental quality is supported by a large number of specific pollution control work. For example, in the past five years, the total discharge of chemical oxygen demand and ammonia nitrogen in China has decreased by 12.9% and 13%, and the daily sewage treatment capacity of cities and towns in China has increased by 57 million tons. Now the sewage treatment capacity of cities and towns in China has reached 182 million tons, making it one of the countries with the largest sewage treatment capacity in the world. There is still a lot of work, which supports the overall improvement of the water environment quality in the country, although the situation is still grim. Environmental protection inspectors found problems, and in some places, some sections of water quality deteriorated and rebounded, but there is no contradiction between the overall improvement of the country and the local deterioration.

  He emphasized that this plan is very clear, and water environment protection should focus on water resources, water environment and water ecology, and the three should be comprehensively considered and treated to implement that "landscape, forest, field and lake are a community of life". In fact, water pollution control is manifested in water, but many problems still come from the shore, so it is necessary to form a systematic whole between water and land. Environmental management should also be managed in accordance with the objective laws of river basins, and refined management should be implemented, so as to implement the requirements of the 13 th Five-Year Plan and realize the protection of water resources, water environment and water ecology.

In the first three quarters, China’s consumer market was generally stable and resumed, and market sales maintained growth.

CCTV News:Yesterday (October 24th), the data released by the National Bureau of Statistics showed that in the third quarter, China’s consumer market generally recovered steadily, and market sales maintained growth.

The data shows that in the first three quarters, the total retail sales of social consumer goods was 32,030.5 billion yuan, up 0.7% year-on-year, with a growth rate of 1-mdash; It accelerated by 0.2 percentage points in August. Quarterly, it increased by 3.5% in the third quarter, and the recovery in the third quarter was faster than that in the second quarter. In September, the total retail sales of social consumer goods increased by 2.5% year-on-year, of which the retail sales of commodities increased by 3%.

Guo Liyan, Director of Comprehensive Situation Research Office of China Macroeconomic Research Institute:At present, the domestic consumer market is also maintaining a stable trend, especially the potential of consumer demand such as online social zero, some emerging consumption and some green and low-carbon consumption is further released, which also drives the development trend of consumer market to stabilize and recover.

In addition, since the third quarter of this year, the Ministry of Commerce has continuously promoted the implementation of the policy of green smart home appliances going to the countryside, promoted the resumption and development of catering, accommodation and other industries, and created new consumption scenarios through digital empowerment and business travel and cultural integration, giving full play to the role of important platforms such as the international consumption season and stimulating consumption vitality. Beijing, Shanghai, Guizhou, Jiangxi and other places have also promoted the upgrading of consumer demand by issuing consumer vouchers and government subsidies.

1-mdash this year; In September, Shanghai won the title of the first store capital in the mainland with the number of 703 first stores. Recently, a number of first stores have just appeared in the waterfront core area of Shanghai Suhewan. This urban complex, which is incarnated from the historical protection buildings such as the Shanghai-style Shikumen building "Shenyuli", presents a rambling consumption experience after ten years of renovation. Among more than 140 brands, more than 70% are the first stores in China, the first in Shanghai and the first in the region.

Near the end of the year, with the opening of several heavy projects, Shanghai will continue to develop the starting economy, brand economy and tax-free economy, and cultivate a number of leading local brands and new online brands. It is expected that Shanghai will introduce more than 800 first stores this year. In Guizhou, since the third quarter of this year, a total of 113 million yuan of travel coupons have been issued to consumers inside and outside the province, which has driven the growth of travel consumption. In Zunyi City, 304 enterprises or merchants involved in tourism, catering, accommodation and retail have been included in the designated use points of cultural travel coupons.

    For today’s smart vendors, it is hard to imagine what is more important than diversified development. A few years ago, the mobile phone was still just a device for talking to us, but with the popularity of intelligent platforms, the mobile phone has changed from a communication device to a multi-functional intelligent terminal. Nowadays, in order to get rid of the homogenization of Android platform, Android manufacturers spare no effort to develop more potential of mobile phones. At this time, we will find that those manufacturers who can integrate the technologies of multiple product lines highlight more advantages than those who simply make mobile phones.

    When CEO Kazuo Hirai took office, we first heard the strategy of "One Sony". This is not the first time for Sony to integrate the technology of other product lines into mobile phones, just like the Walkman series and Cyber-Shot series that we once amazed. This time, Sony once again applied its camera technology to smart phones, and L39h (hereinafter referred to as Sony L39h) became the first product under the concept of One Sony. Just like the words in Kazuo Hirai’s mouth after the release of several DCDV devices in Berlin, "The next product can present the best part of Sony to you at one time."

G lens Sony Xperia comprehensive evaluation

    In terms of configuration, Sony L39h has adopted today’s flagship configuration without any accident. After the slow pace of last year, Sony’s flagship product has finally accelerated its pace in hardware this year, and has always maintained the strongest configuration at the same level as flagship models of other international brands. Like the Sony L36h released at the beginning of this year, Sony L39h uses a 1080p display screen. However, due to the overall improvement in photographing this time, the photosensitive element has also increased to 1/2.3 inch, so the overall thickness and length and width of the fuselage have increased to some extent in Bisogni L36h. The fuselage circumference of this model is 144× 74× 8.5mm, which will be thicker in the hand than that of Bisogni L36h, but relatively, it feels more comfortable because the frame adopts a brand-new flat cutting angle.

Comprehensive evaluation of Sony Xperia Z1 with 20.7 megapixel G lens
Sony’s first image flagship 5-inch 1080p Sony L39h

    Sony L39h is equipped with 2.2GHz MSM8274 Opteron 800 quad-core processor and GPU Adreno 330 image processor, and its outstanding performance is beyond doubt. At the same time, Sony L39h has also continued Sony’s waterproof and dustproof features, reaching IP55/58 level. This means that the phone has a built-in dustproof and waterproof design, that is, all ports and covers are closed, and the phone can be dustproof and can be placed in the deepest 1.5 meters of clean water for up to 30 minutes. Of course, taking photos is the biggest improvement of Sony L39h this time, and we will show it in detail later.

    Regarding the screen that most users pay attention to, the performance of the IPS screen in China made us feel amazing, but this amazing performance did not continue to the Sony L39h used in our evaluation. In other words, Sony L39h, like Sony XL39h, brings users a more vivid and clear visual experience through TRILUMINOS mobile display technology and X-Reality fast image processing engine, but this is only when we watch the screen from the front. When we look at the screen of Sony L39h from the side, the visual effect is still the same as Sony L36h. This really makes us regret. I wonder if the retail version is the same as the prototype used in the evaluation.

    Every year, the flagship product has maintained a high degree of consistency in appearance. In the previous interview, Mr. Morinuma, the designer of Sony L39h, explained that this is first to maintain the continuity and consistency of the design language. But also, each product will be fine-tuned in design and introduce a brand-new design based on the actual experience of users. This time, Sony L39h, like Sony L36h, has adopted a plane-like fuselage line, the camera has no protrusion, and the front and rear sides are also protected by double-sided glass, which gives people a high-end and exquisite impression visually.

Keys are still built into the screen.

    The screen size of Sony L39h is consistent with that of Sony L36h, which means that the change in the length of the fuselage mainly comes from the extension of the upper and lower ends of the screen. The place above the SONY English logo near the frame that looks like a groove is both the receiver and the breathing light. When charging or resting, the lights here will light up. In addition, the front camera located next to the logo has not changed, and it is still 2 million pixels, which is enough for self-timer and can also record 1080p video. At the bottom of the screen, we obviously feel that the "chin" Bisogni L36h of Sony L39h is getting longer, but the Android buttons are still built in the screen. Many netizens wondered why Sony didn’t put the Android button on this slightly longer chin. Although we didn’t get an official explanation, after actual operation, we found that with the growth of smart size, it is actually very difficult for us to hold the Android button on the chin of a mobile phone with a size of 5 inches or more. In other words, actually putting the buttons on the screen is more user-friendly in our actual operation, and it will be better if Sony can let users choose to hide or display these three buttons by sliding up and down in the future.

The bottom of the right side is provided with a hanging hole and a camera shutter.

    Sony L39h adopts a complete seamless design, and uses aluminum frame to make the mobile phone more durable. At the same time, it also uses this frame as an antenna through brand-new technology, which solves the disadvantage of poor call signal of metal body. Sony L39h still designed the main card slots and buttons on both sides of the fuselage, and attached dust plugs, thus maintaining a high degree of visual integration with the frame without affecting the appearance. On the right side, there is still the microSIM card slot, power button and volume button, and at the bottom, Sony L39h has added a photo shutter button, which is also convenient for users to take photos through the physical shutter button when they can’t touch the screen underwater.

The microSD card slot and data interface on the left side of the fuselage support MHL data transmission.

Metal contact for connecting magnetic attraction waterproof charging base

    The design of the left card slot of Sony L39h is somewhat different from that of Sony L36h. The positions of the microSD card slot and the data interface are upside down, with the microSD card slot at the top and the data interface supporting the transmission of microUSB and MHL at the bottom. Sony L39h also has an official standard waterproof charging base, and the metal contact below the data interface is used when connecting with this base.

    Another subtle change of L39h fuselage lies in the design of earphone hole, which is located at the top of the fuselage, but it is not equipped with dust plug like Sony L36h. Of course, users don’t have to worry about water coming into this earphone hole. Nowadays, the application of waterproof nano-coating technology is not uncommon. Personally, I think Sony chose to equip the interfaces on both sides of the frame with dust plugs, mainly for aesthetic considerations. In practical use, especially for people who listen to music on their mobile phones every day, the dust plug in the earphone hole is indeed redundant, and this design is just right.

The earphone hole at the top is not equipped with dust plug this time.

The bottom is almost a speaker, so it won’t block when you hold it.

    Another change comes from the position of the Sony L39h speaker. Sony L36h designed the speaker at the lower right side of the fuselage, which is the position of the Sony L39h camera shutter button. In actual use, if we hold the mobile phone in one hand with the right hand, the speaker will be easily blocked, and the movement of the hand will directly cause the sound of the speaker to be loud and small. This time, the speaker is designed at the bottom, which is a good solution to this problem. This change is still very intimate.

The back is still a whole glass design.

XPERIA capital logo at the bottom of the back

    The back of Sony L39h’s fuselage is still full of glass, and the explosion-proof membrane is also pressed for protection when it leaves the factory. This design is really beautiful, but it is also easy to be contaminated with fingerprints. Relatively speaking, white is the color with the least fingerprints among the three colors of black, white and purple. Sony’s English logo is located in the center of the fuselage. Above is the mark of NFC position, and below is the word XPERIA in all capitals. This time, it seems to emphasize the advantages of taking pictures. It is rare for Sony to mark the G word of G lens next to the camera, as well as the camera pixel size of 1/2.3 inch sensor and 20.7 million pixels. It can be seen that Sony is indeed full of confidence in taking pictures of this product.

    L39h is equipped with Android 4.2 jelly bean system, but it does use a slightly different UI from Sony L36h upgraded to Android 4.2. Of course, the difference between the two is not very huge. At least as far as the main interface and the unlocking interface are concerned, we have not found any difference in the operation mode. At most, the buttons that enter the application interface are designed differently.

The theme of Sony L39h (left) has changed a lot from Sony L36h.

  Like the Sony L36h, the Sony L39h can change the theme and add widgets and applications to the home screen by pressing and holding the home screen. By contrast, we can see that the theme of Sony L39h has changed obviously. At the same time, when we do this operation, the presentation form of the thumbnail of the upper home screen is also different, from white translucent to black translucent, which is more visually recognizable.

    In the application interface and drop-down notification bar, Sony L39h has also changed. In the past, we need to click the button in the interface to call out the menu of unloading and sorting, but in Sony L39h, we just slide the screen to the far left and call out the corresponding menu. When we drop down the notification bar, we can see that the shortcut operation buttons of Sony L39h have been expanded from one row to two rows, but we still don’t support setting the buttons independently.

Sony L39h (left) changed to X-Reality for mobile.

    The change of display interface is also obvious. One of the highlights of Sony L36h is that you can manually adjust the white balance settings, but in Sony L39h, the white balance option has been cancelled. But in contrast, in Sony L39h, the original Bravia Engine 2 was replaced by the latest X-Reality for mobile, and a new backlight optimization mode was added. X-Reality for mobile can make the picture presented to us clearer and more vivid, which can be regarded as another upgrade of Bravia.

    In terms of function, there is not much innovation in this L39h, which continues the characteristics of Sony L36h and the middle school, such as sketch function. On the whole, Sony L36h put all the emphasis on taking pictures. Let’s take a look at how the new camera flagship of this Android platform performs.

Comprehensive evaluation of Sony Xperia Z1 with 20.7 megapixel G lens
Sony L39h, the biggest change is taking pictures.

    Sony L39h has three key words in taking pictures, namely, 1/2.3-inch large Exmor RS layered image sensor, Sony G lens, and mobile BIONZ image processor. So how does Sony explain these three keywords?

    The main camera of Sony L39h has been achieved, and the 1/2.3-inch Exmor RS laminated sensor can capture more scene light and make full use of the powerful function of camera lens to shoot ultra-high resolution images. The sensor has higher sensitivity, which can reduce noise, ensure smooth and clear images, and completely reproduce all wonderful details with higher fidelity. Sony G lens is a unique feature of Sony used in cameras, which has extremely high in-focus imaging quality. In addition to sharpness, it also has excellent light gathering ability. The F2.0 large aperture 27mm wide-angle lens adopted by Sony L39h can perform better in low light and capture more light.

    In addition, in order to get better detail reproduction effect, Sony L39h also uses the powerful algorithm of Sony mobile BIONZ image processor to make the shooting picture more vivid and realistic. Ultra-high pixel resolution, automatic exposure and automatic white balance ensure the accurate presentation of the colors captured by Sony G lens-while achieving brightness balance, the colors are enhanced and reproduced with rich texture layers and layers, and the effect is the same as that seen by the naked eye. The combination of 1/2.3 inch 20.7 megapixel mobile Exmor RS layered sensor and mobile BIONZ image processor can also eliminate noise.

    Finally, a new breakthrough of Sony L39h lies in the zoom of 3x clear image. When shooting at a long distance, the high-resolution sensor and the mobile BIONZ image processor can provide users with an optical zoom of 81mm, bringing the picture closer, and the details are still clear. Of course, as our text shows, it is limited to zoom 0 distortion within 3 times.

Long press shutter continuous shooting needs to be set in advanced automatic mode.

    In fact, the basic camera function of Sony L39h is not much different from that of the past. However, it should be noted that there were various scene modes for us to choose from in Sony in the past. However, in Sony L39h, users can’t manually select the scene mode, but can only automatically identify the most suitable scene mode at present through the "advanced automatic" mode. In addition, the function of continuous shooting requires us to open the option of long-press the shutter button continuous shooting in the setting menu of "Advanced Auto" mode. Frankly speaking, the setting of these small options is actually more complicated than before.

    After reading the basic functions, let’s take a look at the featured functions in L39h. Obviously, the time shift function of Timeshift Burst, the information acquisition function of Info-eye and the shooting function of AR augmented reality are the three most interesting camera functions in Sony L39h. How to play these functions?

Info-eye function in Sony L39h

    The function of Info-eye is very interesting, and we can use it as a new way to get information. Info-eye can shoot landmark buildings, characters, red wine, business cards and other formulated objects. As long as we shoot through the camera viewfinder, we can immediately see the relevant information obtained by networking.

Comprehensive evaluation of Sony Xperia Z1 with 20.7 megapixel G lens
Timeshift Burst function, the user can capture it without fail.

    Timeshift Burst’s time shifting function is actually to help users capture the best photos through ultra-high-speed continuous shooting. When the shutter is pressed, the Timeshift Burst time shift function will completely record 61 images in one second before and after the shutter. After taking pictures, we just need to dial the photos in the turntable and choose the best one to save.

    The fun photo function of AR augmented reality is very suitable for users with children at home, or for multi-party to enliven the atmosphere. Sony L39h provides us with seven interesting AR scenes. When the face is recognized, Sony L39h will automatically add funny accessories such as hats and glasses to the face, and the addition of these AR animations is also very intelligent. When there is a plane in the picture, these animations will be placed on the plane, and there will be no unscientific pictures such as corals floating in the air or mushrooms appearing overhead.

Comprehensive evaluation of Sony Xperia Z1 with 20.7 megapixel G lens
Sony L39h still comes with 9 kinds of filters.

    In the Sony L39h, nine kinds of camera filters used in Sony are retained, so users can take photos of various small and fresh literary styles directly through the camera in their mobile phones according to their own needs.

     After introducing the innovation of L39h camera technology and the breakthrough of camera function, we should also take a look at the photo proofs of Sony L39h. Because Sony L39h is a product that has made a big breakthrough in taking pictures, we also chose the flagship Sony L36h at the beginning of this year for comparison. Although there is a big difference in the number of pixels between the two, it is really unfair to compare them, but it is also part of Sony L39h’s photo improvement. We will present the proofs in outdoor, indoor, macro and low light, and the AR proofs of Sony L39h will also be attached.

    The outdoor proofs in the daytime are divided into two situations, one is that there is enough light in the sun, and the other is that the shade is relatively backlit. Sony L39h’s color in the sample under the shade of the tree is more realistic than Bisogni L36h’s, and the degree of protection is higher. However, in a sunny environment, perhaps due to the large amount of light entering Sony L39h, the overall color tone is a little whiter than Sony L36h, but at the same time, the details of trees in the distance are richer.

    We took a lot of indoor proofs, and chose the shopping mall as an environment with complicated light for comparison. We can clearly see that Sony L39h’s ability to aggregate light is much better than that of Bisogni L36h. At the same time, Sony L36h appeared obvious color cast when shooting indoors, while Sony L39h restored the real color in place and controlled the noise well.

    Next, we will challenge the low light and macro of L39h and the effect of AR photography. In low light, we chose indoor and outdoor situations. Strictly speaking, the two macro photos were also taken in low light environment.

Sony L36h Weak Light Proof (Indoor)

    Sony L39h did a good job in the part of taking pictures in low light. First of all, while improving the brightness, the color is more natural, and there is no loss of some details. The picture of the building was taken at sunset in the evening, and both Sony L39h and Sony L36h automatically improved the overall brightness of the picture. However, we can find that the billboard in the Sony L36h sample has obvious details missing, and the building itself also appears white and the contrast is not strong enough. When shooting at night after the sky is completely dark, although the performance of Sony L36h is still satisfactory, it is obvious that there is a certain gap in saturation compared with Sony L39h, and the color of the picture is not vivid enough. In the last indoor low-light shooting session, the proofs of the two devices have obvious differences in fineness. Because Sony L36h will smear seriously in order to reduce noise when shooting in dark light, the overall picture gives us a little fuzzy feeling.

    In macro aspect, both Sony L39h and the previous Sony L36h have a good performance, and the blur of the background is in place. The only difference between them is that they are both shooting outdoors in the evening, but the brightness of Sony L39h is higher.

Sony L39h AR model proofs

    Finally, let’s look at the photo proofs in AR augmented reality mode. Because the dinosaurs or other animations in the picture are constantly moving, the photos taken by everyone must be different. AR animation is very smart to attach to the ground or desktop, and when taking a portrait in AR mode, hats, glasses, etc. will be added to the corresponding positions and will move with the movement of the portrait. However, if we cover a part of the face with our hands, or shoot the side face, these AR elements will not appear on our face.

    Generally speaking, the camera performance of Sony L39h has been greatly improved compared with Sony L36h, but in the process of actual use, we also found some shortcomings. Sony L39h’s imaging speed is a little slower, so it is easy to take a photo because of hand shaking, which will be more obvious when shooting in low light. In addition, it is AR mode, and the effect of shooting through the main camera in low light environment is not very ideal. We hope that Sony can optimize this in the future.

    Next, let’s look at the multimedia performance of L39h. First of all, in terms of video, it is definitely no problem for Xiaolong 800 to play 1080p video, but some formats that Sony comes with cannot be played, and we need to play them through soft decoding of third-party players.

    Sony L39h, like Sony L36h and Sony L36H we evaluated before, plays mpg with the help of a third-party player. But overall, the mobile phone plays 1080p video quite smoothly, which also provides a solid hardware foundation for Xiaolong 800. Sony L39h’s video player can also set sound effects to bring a better viewing experience.

Only when playing music can it be fixed in the unlocking interface.

    In terms of audio, Sony L39h can play the audio files in m4a, ogg, wav and mp3 formats we tested, but the ape format can only be played with the help of a third-party player. The music player is not much different from the recently upgraded Sony L36h, and just like the Sony L36h, the music player can only be displayed on the unlocking interface when playing music, which means that we can’t directly access the music player from the unlocking interface at ordinary times, but need to unlock it first and then click to enter, which is somewhat inconvenient.

Playing online web videos is quite smooth.

    Perhaps because it is not the final retail version, the application of Sony L39h we evaluated is not very complete. Just for exampleWhen we want to test the online experience, we find that there is no preset in the mobile phone, so we will test it in Sony Select.Sony L39h’s performance in loading web pages, zooming and playing videos is very smooth, which makes it difficult for us to pick out any shortcomings. With enough hardware in place to support it, Sony L39h’s performance is taken for granted.

    Hardware configuration is not the biggest publicity highlight of L39h this time, but in any case, for most users, hardware is always one of the first factors to consider when choosing a product. Sony L39h is equipped with a 1080p display screen, and has chosen the top Opteron 800 processor in Qualcomm at 2.2GHz, supplemented by 2GB RAM and 16GB body storage space, of which the space available for users has reached 11GB. Following the first release of this world’s earliest release, Sony L39h is also the second intelligence equipped with the Opteron 800 processor in Sony products.

    In addition to the advantages of performance and speed, Xiaolong 800 processor also has excellent battery life. You can run multiple applications at the same time, surf the Internet quickly, and play videos smoothly, which are all intuitively reflected in our previous evaluation. In addition, the Snapdragon 800 series MSM8274 quad-core processor with 2.2GHz frequency adopted by Sony L39h is an asynchronous processor, and each core supplies power independently. The battery power will be accurately allocated according to the user’s use needs, thus achieving the effect of saving electricity. In addition, with the STAMINA power-saving mode in Sony L39h, the worry-free use of the whole day under normal intensity is not a problem.

Rank/comparison in AnTuTu Sony L36h

    AnTuTu Runfen recently released the latest version of V4.0, in addition to the previous four test items of CPU, RAM, GPU and IO, this time it also added the user experience rating item. AnTuTu said that "in the traditional test, the performance limit of hardware will be emphasized, but the highest score of the test can not fully reflect the operating efficiency of the system", and AnTuTu thought that "multitasking ability is a very important indicator. The processing efficiency of multi-core and multi-task will directly affect the fluency of the whole system. " Therefore, AnTuTu V4.0 adds MultiTask Multithread Performance Test, and quantifies the optimization degree of UI/ROM through Dalvik. At the same time, AnTuTu V4.0 also provides 3D performance test in ES 3.0 environment, so the AnTuTu running score in this version is not comparable to that in the previous evaluation, and we can only compare it through the popular model rankings given by AnTuTu for the time being. Obviously, Sony L39h, which runs at 30444, does have the superiority of the flagship model. Compared with Sony L36h, the score is improved obviously.

When Sony CEO Kazuo Hirai took office, we first heard the strategy of "One Sony". This is not the first time for Sony to integrate the technology of other product lines into mobile phones, just like the Walkman series and Cyber-Shot series that we once amazed. This time, Sony once again applied its camera technology to smart phones, and Sony Xperia Z1 L39h became the first product under the concept of One Sony.

The Central Meteorological Observatory issued a typhoon blue warning at 06: 00 on August 31.

  The Central Meteorological Observatory issued a typhoon blue warning at 06: 00 on August 31:

  This year’s No.9 typhoon "Maysak" was upgraded from typhoon level to strong typhoon level last night. At 5 o’clock this morning (31st), its center is located in the northwest Pacific Ocean about 530 kilometers east of Naha, Okinawa, Japan, which is 21.6 degrees north latitude and 128.8 degrees east longitude. The maximum wind force near the center is 14 (42m/s), and the lowest pressure at the center is 950 hectopascals.

The best nurse in ICU has been fighting for 49 days! Pull up a 60-kg oxygen tank and still run fast.

CCTV News:Intensive care unit is the last line of defense to save the lives of critically ill patients in COVID-19. Doctors and nurses in the intensive care unit of Jinyintan Hospital in Wuhan have been fighting for 49 days since they received the related patients on December 29th last year.

At the 2020 Spring Festival Gala at the reception desk, hundreds of millions of viewers got to know this nurse in protective clothing. When they saw this nurse named Liu Hongjuan again after more than 20 days, she had just come out from work in the ward. Talking about the work scene shown on the Spring Festival Evening, Liu Hongjuan said that she was actually very tired at that time.

Liu Hongjuan, nurse in intensive care unit of Wuhan Jinyintan Hospital:At that time, the support people had not arrived, and our physical strength was in an overdraft state. I took care of three patients, and the patients’ condition was not very good. The air supply system on their backs was ten kilograms, and then they were busy. The patients had to be rescued, so they couldn’t take care of themselves.

Nurses who are busy in the intensive care unit have more than five years of experience. This job is dangerous and heavy. All 48 nurses have been working for a month and a half without a day off.

Qu Zhaohui, head nurse of intensive care unit of Jinyintan Hospital in Wuhan:Generally speaking, if you go in, you may stay in it for twenty or thirty minutes, and you will feel chest tightness and discomfort, but my nurse, she will stay for at least five to six hours, and the longest will stay for 10 to 12 hours. We are all the best nurses.

The best thing is not only technology, but also physical strength. It is still fast to pull up a 60-kg oxygen tank!

Song Jingyuan, nurse in intensive care unit of Wuhan Jinyintan Hospital:The patient uses high-flow oxygen, and the concentration needs to be very high. A can of oxygen can only be used for half an hour.A patient needs it one day.More than 20 bottles, nearly 30 bottles.

Nurses take turns in shifts and wait around critically ill patients 24 hours a day. Nurses carry out all the doctor’s orders, including basic nursing care for patients, such as turning over, patting back, sucking sputum, caring for gastric tubes, urinary tubes, arteriovenous catheters, thoracic and abdominal drainage tubes, etc., always paying attention to patients’ vital signs such as ECG, blood pressure, oxygen saturation, etc., in addition, they have to undertake life care such as feeding, nasal feeding, washing hair, cleaning urine and so on, and are often exhausted at the end of the day.

Lu Li, nurse in intensive care unit of Wuhan Jinyintan Hospital:After all, this is an infectious disease. Although we are wearing layers of protective clothing, it can protect us to a certain extent, but because it is closed inside the protective clothing, it will also affect our hearing, smell and sensitivity. In case we are not careful, we may be pricked by needles, contaminated by blood and body fluids, and then when we suck sputum or do other operations, there may be droplets splashing on our faces, which is actually quite dangerous.

On January 23rd, Wu Wenjuan, director of the intensive care unit, suffered from headache and fatigue due to staying up late and working hard. CT showed that there was a ground glass image in his lungs, and he was isolated and hospitalized. Although fully prepared for the virus infection, when I heard that Director Wu Wenjuan was suspected to be infected, all the people in the department inevitably experienced emotional fluctuations.

Ma Dan, nurse in intensive care unit of Wuhan Jinyintan Hospital:What if I get infected? Then my dad said, people always have to do something meaningful in this life, and when you look back when you are old, you will feel that you won’t have any regrets. He said that you should leave things at home alone, and then work hard and work with peace of mind.

All the medical staff silently withstood the pressure, and Ma Dan not only returned to his post, but also submitted an application for joining the Party.

Ma Dan, nurse in intensive care unit of Wuhan Jinyintan Hospital:If we don’t stick to our posts, then no one can do what we do, and no one will stick to it. We should move forward unswervingly.

Fortunately, after treatment, Director Wu Wenjuan quickly returned to work.

The amount exceeds 100 million? Being reported to be suspected of fraud, Wang Baoqiang responded

On the evening of November 21st, # Wang Baoqiang was reported to be suspected of fraud # and the topic rushed to the hot search.

In this regard, @ Wang Baoqiang Studio issued a claim that "the money signed in black and white is not bad, and the promised help has never been broken. Innocent in the heart, and never trust, we are waiting for the legal result. "

Earlier, it was reported on the Internet that Wang Baoqiang was suspected of fraud, amounting to 100 million yuan.

According to the news, on the morning of 21st, the head of Chengdu Enbo Fighting Club reported to the Unity Police Station in Pidu District, Chengdu, that the club gave full support to Wang Baoqiang’s film when he co-produced with Wang Baoqiang, and it took five years to invest millions of human, material and financial resources. The club was promised a 5% share of the box office. Later, the box office sold 2.2 billion yuan. However, Wang Baoqiang turned his back on the club and ignored it. So far, he has not paid any return and remuneration, which has caused great problems in the management of the club. The club thinks that it has been tricked by Wang Baoqiang and his company, caught in a scam and forced to call the police.

In an octagonal cage is a sports inspirational film directed and starring Wang Baoqiang in 2023. Based on real events, the film tells the story of a frustrated middle-aged man leading a group of children to highlight the tight encirclement of fate and explore the way out of life. The film was released in Chinese mainland on July 6th, 2023, and the subsequent box office grossed over 2 billion yuan.

As early as October this year, Wang Baoqiang’s "octagonal cage" was also in a controversy. A young actor in the film said that Wang Baoqiang had promised to support him until he graduated from college, but so far he has not fulfilled it. On October 18th, coach Sun, the head of the actor’s sloppy side, responded to the media that everyone was just chatting at that time, and the online recording was stolen, and Wang Baoqiang didn’t make a promise to them.
