Hold your breath for 24 seconds to test lung function and blood oxygen level? Doctor: It is unscientific to verify antiviral ability by holding your breath.

  These two days, a small experiment of "self-testing against coronavirus" suddenly became popular on the Internet! Experiments show that as long as you hold your breath according to the instructions in the animation, you can judge your lung function and blood oxygen level and whether you have the ability to resist coronavirus. Many people believe it and do it. So, is this experiment really reliable? "Reaching the standard" can prove that you have the ability to resist Covid-19?

Hold your breath for 24 seconds to test lung function and blood oxygen level? Doctor: It is unscientific to verify antiviral ability by holding your breath.

[Hold your breath continuously for 24 seconds to test lung function and blood oxygen level]

  This small test of "self-test against coronavirus" shows that as long as you can hold your breath from A to B, it means that your lung function and blood oxygen level have the ability to resist coronavirus. The reporter calculated that this breath-holding time is about 24 seconds, and most people can do it. But in fact, the length of holding your breath is influenced by many other factors, such as age, height, weight and subjective will. Experts say that the time of holding your breath reflects the state of a person’s cardiopulmonary function. Usually, as long as you hold your breath for more than 30 seconds after taking a deep breath, the doctor thinks that your cardiopulmonary function is normal.

  Liu Hong, deputy chief physician of the Department of Thoracic Surgery, Nanjing Second Hospital, said: "Holding your breath is not a matter of time, but a matter of integrating various factors. Conventionally speaking, holding your breath for more than 30 seconds can basically tolerate a chest operation. But actually I hold my breath for 20 seconds, can’t I have a chest operation? That’s not what I said. We should combine his lung function test, heart function test and electrocardiogram. "

[Doctor: It is unscientific to verify antiviral ability by holding your breath]

  At present, the breath-holding test is only used as a supplementary means of lung function examination in clinic. This simple and rough method is not accurate, and the formal lung function examination is much more accurate. Therefore, it is not reliable to judge whether a person has the ability to resist coronavirus just by holding his breath for a long time.

Hold your breath for 24 seconds to test lung function and blood oxygen level? Doctor: It is unscientific to verify antiviral ability by holding your breath.

  Liu Hong said, "I got this disease, pneumonia and lung infection. Can I have a good prognosis or a bad prognosis?". This is caused by many factors, and can not be evaluated simply by a breath-holding test. This is a very wrong conclusion. Whether another ordinary people can be infected with the corresponding diseases in public places. For example, infectious diseases such as influenza and pneumonia have nothing to do with breath-holding test, but are related to personal immunity and the amount of bacteria and viruses in the environment you are exposed to. "

  In addition, the breath-holding test needs to be operated under the guidance of medical staff. It is unnecessary to do the breath-holding test yourself, and it will also induce risks.

Hold your breath for 24 seconds to test lung function and blood oxygen level? Doctor: It is unscientific to verify antiviral ability by holding your breath.

  Liu Hong said: "For example, patients with hypertension or coronary heart disease, or patients with poor lung function and asthma, these patients may induce some diseases by holding their breath. For this group of people, this kind of self-testing may bring certain risks. "

Foreign media counted China’s most outrageous cottage car Yujie Geely Shuanghuan Chaozhongtai twice on the list.

  Both consumers and employees in the automobile industry scoff at the mention of fake cars, but whether you admit it or not, the history of China cars is composed of one fake car after another. A few days ago, Autocar, a famous British automobile professional media, claimed that China’s automobile industry likes to copy cars with the title of Dead Ringers: History of the Chinese Copycat Car (A Goods: History of China Counterfeit Cars), and counted the most outrageous cases of China Counterfeit Cars. The original text is compiled as follows.

  China knockoffs are rapidly becoming the main force in the local market, as shown by Zotye SR9 and Vekery V7, and they even make no secret of imitations from Porsche Macan and Volkswagen e-Up.

  In recent years, China’s automobile industry has got rid of imitation, and many independent brands have even launched landmark competitive new cars in Europe and the United States. However, even the biggest brands have more or less had shanzhai cars in their product lineup. Therefore, please follow us to see the most outrageous knockoffs in these years.

  The BMW round logo design has also been copied, although the form has been adjusted. Although it is more decent than the cottage car, it is obvious where the font, color scheme, shape and layout of BYD logo come from. BMN, a China clothing brand, is also facing a lawsuit from BMW for its round logo. But that’s all.

  Although the comments of British media Autocar are full of arrogance and disdain, the cottage car has always been a topic that cannot be avoided in the development of China’s automobile industry, and it is also a microcosm of the history of China’s automobile industry. Thanks to the unremitting efforts of several generations of China autobots, the pace of catching up with the century-old automobile manufacturing power has been accelerated, the gap has been continuously shortened, and more and more autonomous vehicles have gone abroad to enter the European and American markets.

Drink Wang Laoji herbal tea to prolong life by 10%? The conclusion of rat experiment may not be applicable to people.

  The project involved in the 863 Program is actually a study on the safety of functional food, and the purpose of the study is not to extend the life.

  On December 5th, Weibo, the official website of Wang Laoji, announced that according to the research results of the National 863 Program, drinking Wang Laoji can prolong life span by 10%. After this statement was released, it was quickly questioned by netizens about the authenticity of the project and the scientific nature of its conclusions. Beijing Youth Daily reporter found that herbal tea brands such as Wang Laoji were indeed used as experimental objects in a sub-project of the 863 Program. However, according to the introduction of Guangzhou CDC, which participated in the project, the center has only done relevant experiments on rats, and it is not sure that the effect of "prolonging life" is also applicable to humans. Many experts in related fields said that there is no functional food, even medicine, that can claim to prolong human life by 10%.

  Wang Laoji claims to prolong his life by 10%

  On December 5th, a news about herbal tea Wang Laoji was widely spread on the Internet. Li Chuyuan, chairman of Guangzhou Pharmaceutical Group, announced at a forum that the research results of the National 863 Program show that drinking Wang Laoji can prolong life by about 10%. But soon this news caused a lot of questions.

  The first person who questioned this idea was the CEO of Huada Gene in the same industry. On the afternoon of the 5th, Weibo, the official of Wang Laoji, announced that Li Chuyuan, chairman of Guangzhou Pharmaceutical Group, had a high-end interaction with Yin Ye, CEO of Huada Gene, and other guests at the China Medical Industry Forum. Li Dong said that "according to the research results of the National 863 Program, drinking Wang Laoji can prolong the life span by about 10%", which was immediately highly recognized by President Yin Ye of Shenzhen Huada Gene Co., Ltd. and warmly applauded by all the guests.

  On the afternoon of 6th, Yin Ye, CEO of BGI, forwarded the Weibo and explained that the so-called "high recognition" was just a courtesy nod. He said: "Although I am in the same industry and drink Wang Laoji, it does not mean that I recognize this conclusion. The extension of human life span is a comprehensive issue, and so far no single factor can form such a significant difference. "

  In addition to peers, many netizens have also left messages under Wang Laoji’s official Weibo, saying, "Believe in advertising, you can prolong your life by 100%, just give your brains.". Others questioned, "How is 10% calculated? So many health products in China didn’t dare to say that, and finally lost to a drink seller. ".

  Previously, it was caught in the "life extension storm"

  The reporter of Beiqing Daily found that this is not the first time that Wang Laoji claimed that he has the effect of prolonging his life. On June 13th, 2013, GPHL held a special press conference, saying that "Wang Laoji Herbal Tea has the function of prolonging animal life".

  At the press conference, GPHL said, "Through a two-year safety test on 576 mouse samples, it was initially found that the survival rate of rats in the experimental group of Wang Laoji herbal tea was better than that of the control, indicating that Wang Laoji herbal tea has the function of prolonging animal life … …”

  At that time, it was not long before Guangzhou Pharmaceutical officially recovered the brand of Wang Laoji, and the news about "Wang Laoji prolonging life" immediately caused widespread doubts. Some netizens said, "How long does it take to extend the life of animals to be scientifically verified? It was less than two years before Guangyao officially recovered Wang Laoji, and this magical result was actually measured! " Others ridiculed, "After Radix Isatidis, another dose ‘ Shenyao ’ Available. "

  Despite the surging doubts, the relevant person in charge of Guangzhou Pharmaceutical firmly believed in the authenticity of the efficacy of prolonging life when interviewed by the media, and said that this was only a phased achievement, and the next step would be to continue research.

  Sure enough, on January 6, 2016, Wang Laoji once again released a "breakthrough" scientific research achievement: according to national standards and US FDA standards, the three-year safety system study of the first herbal tea product in China showed that long-term drinking of Wang Laoji herbal tea could prolong the life of animals.

  According to reports, this conclusion is the first herbal tea project in the National 863 Plan. Guangdong Provincial Center for Disease Control and Prevention, as a scientific research unit, undertook the research on functional food safety evaluation factors.

  "According to the requirements of national standards and American FDA standards, the research group conducted a two-year safety system study on mouse samples, and found that the survival number and expected average survival time of the experimental group of Wang Laoji herbal tea were higher than those of the control group. The statistical survival time of the experimental group of female rats given 2.90g/kg BW of Wang Laoji herbal tea was 708.2 days, while the statistical survival time of female rats in the control group was 675.1 days, which was 33.1 days higher. The difference was obvious, which proved that drinking Wang Laoji herbal tea for a long time could prolong the life of animals. At the same time, related research was carried out according to the human consumption rules of functional foods, and it was found that the physical examination indexes such as liver and kidney function, blood lipid classification and blood routine of the subjects, respiratory system, digestive system, urinary system and mood all improved to some extent, which proved that drinking Wang Laoji herbal tea for a long time had a positive effect on health. " Although specific data have been released, Wang Laoji’s function of "prolonging life" has not been widely recognized because the report only involves experiments related to rats.

  As for the "life extension" storm, Wang Laoji responded on the evening of December 6 that the conclusion of life extension was obtained from 576 rat samples, and the relevant statements were basically consistent with the information released in 2016.

  Survival rate is mainly used for safety verification.

  On December 6, Huang Junming, director of the Institute of Health Toxicology of Guangdong Provincial Center for Disease Control and Prevention, admitted to the reporter of Beiqing Daily that the center had indeed participated in related 863 projects. "This project exists, and the project number is 2010aa023001. However, we only participated in the experiments of early rats and were not responsible for the human experiments. "

  According to Huang Junming, the members of this 863 research group include several universities, several research institutions and many enterprises. At that time, it was a huge project, herbal tea was only one of the sub-items, and our team was responsible for part of the work.

  He recalled the operation of the project to the reporter of Beiqing Daily. At that time, there were three herbal teas participating in the experiment. Among them, Jiaduobao and Wang Laoji’s experiments involved the survival rate of rats, both in red cans and green boxes. Another brand product does not involve this indicator. "Our animal experiments mainly focus on the safety of herbal tea, and the final survival rate of rats is an index to investigate the results." Huang Jun Ming said, "The experiments in which Jiaduobao and Wang Laoji participated were successful, and the animal survival rate reached the previous experimental design. The fact of the experiment was that the rats who used herbal tea lived longer than those who did not."

  Huang Junming repeatedly stressed: "The survival rate is only the result of our experiment, not the purpose of the experiment. As to whether Wang Laoji has the function of prolonging life, I can’t give a conclusion. As for how the company publicizes, it is beyond our control. "

  When asked about the funding of this scientific research project, Huang Junming said that all scientific research projects are supported by funds. In addition to the higher-level funding, all units that undertake the project also have inputs. "At that time, Wang Laoji, Jiaduobao and another herbal tea company provided strong support in terms of samples, materials, production, processing and experiments, which ensured the smooth progress of the project."

  A staff member of the Guangdong Provincial Center for Disease Control and Prevention said that the research results released by Wang Laoji only mentioned about 10% of the experimental results, but did not provide specific experimental details and experimental data, and even the experimenters did not mention it. "The result is very vague and the words are unknown, so we are also verifying it further, but we are not responsible for this experimental result for the time being."

  Expert: Herbal tea is not suitable for everyone.

  Wang Fengzhong, deputy director of the Institute of Agricultural Products Processing, Chinese Academy of Agricultural Sciences, said that because rats and humans belong to different species, the conclusions obtained in rat experiments may not necessarily apply to humans.

  Wang Fengzhong said that related efficacy tests often require a series of animal tests such as fruit flies, rats and monkeys, and finally human trials. Due to the complexity of human body structure, many ingredients that work on animals may have little effect on human body. "If we want to prolong human life by 10%, we need to prolong life by at least 30% in rat experiments."

  Wang Fengzhong introduced that at present, there is no such thing as "prolonging life by 10%" in the related experiments of functional foods. "Now no one dares to say that it can improve human life span by 10%, and even drugs dare not claim to have such effects."

  Wang Fengzhong said that herbal tea is not suitable for everyone to drink. "Every product has its optimal population, and it is impossible for a certain product to cure all diseases. Just as some people are allergic to eating eggs, herbal tea cannot be beneficial to everyone. "

  Fan Zhihong, an associate professor at the College of Food Science and Nutritional Engineering of China Agricultural University, told the reporter of Beiqing Daily that to prove that Wang Laoji has a certificate of life extension, it is necessary to produce accurate research data. "The conclusion without data is unbelievable from my personal point of view", and there is no related research on whether it is vitamin drinks or energy drinks.

  Fan Zhihong said that this kind of research on life extension needs to be followed for many years, and the sample is very large, and all kinds of mixed factors should be avoided, that is to say, other factors affecting life should be excluded to prove that only one factor has an impact.

  Fan Zhihong said that she didn’t know much about the traditional Chinese medicine ingredients in the formula of Wang Laoji herbal tea, but as a high-sugar beverage, it was not suitable for everyone to drink. In addition, from the perspective of publicity, it is not appropriate to highlight the life-extending effect of products. Ordinary food cannot publicize its efficacy, even if herbal tea belongs to health care products, "prolonging life" is not among the efficacy of health care products.

  The reporter of Beiqing Daily inquired from the website of china food and drug administration that the food and beverage branch of Guangzhou Wanglaoji Pharmaceutical Co., Ltd., the parent company of Wanglaoji Herbal Tea, registered its products as plant drinks, which means that Wanglaoji Herbal Tea is a beverage and not a health care product.

  According to the relevant provisions of the Technical Specification for Inspection and Evaluation of Health Foods (2003 edition) issued and implemented by the Ministry of Health in 2003, health foods with health claims can declare 27 functions such as enhancing immunity, antioxidation, assisting in improving memory, relieving physical fatigue and losing weight, which does not include the function of prolonging life.

China Weather Network issued a cotton trousers warning map: The coldest week in the south, look at how many you have to wear.

At the beginning of January, the cold wave has just dissipated, and this week, a new round of cold wave has struck strongly. The cold air has a long endurance, and the cold will run through the end of January. Autumn trousers can no longer be carried, and the ultimate equipment such as wool trousers and cotton trousers should be put on the upper body! China Weather Network released a national cotton trousers warning map, to see how many cotton trousers you should wear at least in your area.

The pictures in this article are all from "China Weather Network" WeChat WeChat official account

When it comes to the cold wave, everyone still remembers the boss-level cold wave in January 2016. This cold wave process is also coming, so which of the two processes is stronger? According to Bao Yuanyuan, a senior engineer of the National Meteorological Center, the cold wave process in early 2016 cooled down quickly and fell sharply; This process affected for a long time, and the temperature gradually decreased. Just like the fan’s direct blowing mode and head-swinging mode, one is simple and rude, and the other is long-lasting.

Compared with 2016, the overall degree of low temperature is slightly weaker, but the polar vortex continues to be stable in the northeast, and the temperature in the northeast is very low. Monitoring shows that the local temperature in Heilongjiang has fallen below -45℃ this morning. In the next three days (24-26), the freezing cold will continue, and the lowest temperature in most parts of Northeast China, northern Xinjiang and central and eastern Inner Mongolia will be below -28℃. Among them, Harbin’s performance is particularly outstanding, and it will be even colder than the "overlord cold wave" in 2016. The lowest temperature on 24th and 25th will reach -35℃, while the lowest temperature recorded in 2016 is -31.4℃. The temperature in the freezer of the refrigerator is generally -18℃, and these areas are even colder than the freezer, which is sour and unimaginable.

Therefore, people in the above areas can wear as much as they can. Autumn trousers, woolen trousers, cotton trousers, down jackets, and clothes that can be worn should be put on the body as much as possible. Temperature is more important than demeanor. If there are not enough cotton trousers at home, you can only rely on fat to make up.

This morning, the temperature in Beijing dropped to -12.3℃, a record low this winter. In the next three days, the minimum temperature will be below -10℃ from the eastern part of northwest China to Beijing, Tianjin and Hebei. On the morning of 24th-25th, the -10℃ line will reach Shandong and northern Henan. "Everyone is looking for her, and your mother calls you to wear cotton trousers." At this time, it is not your mother who thinks you are cold, but it is really cold. Put on your big cotton-padded jacket and trousers quickly.

Today, cold air has spread to Jiangsu, Anhui and Hubei, and will gradually move southward in the future. On the morning of 25th, the lowest temperature in Zhejiang, northwestern Jiangxi and southern Hunan also dropped below 0℃. In addition to being cold at night, the temperature hovers around the freezing point during the day, from morning to night. This week will be the coldest week in winter in the south, that is, it will be colder than the cold wave period in early January. What’s more, a wide range of rain, snow and freezing rain will be on the line soon, and it will last for several days. In big cities, Hefei, Nanjing, Wuhan, Changsha and Hangzhou, it has been rainy or cloudy for four or five consecutive days since Wednesday (24th). Cooling+rain and snow, this wave of wet and cold magic attacks is too fierce! Therefore, friends in the south, I suggest you put down your last stubbornness and put on cotton trousers. However, in the south where there is no heating, even if it is wrapped in a ball, it still shivers and can only be warmed by shaking.

Do you think the cold air will end on the 26th? The recent cold air can be described as endless. From 27th to 30th, due to the influence of supplementary cold air, the temperature in most parts of China will drop, and the lowest temperature in northern Guangxi, northern Guangdong and northern Fujian will also drop below freezing point. Come out to mix, sooner or later, people in South China, cold air is coming.

However, at this time, there are still some areas in China that can wear as much as possible, such as southern Hainan and Xishuangbanna, Yunnan, where the highest temperature is still around 30℃. At this time, don’t take selfies in shorts and sandals in the circle of friends, and be careful that southern friends who are frozen into dogs will hit you.

In short, in late January, most of China continued to be cold, and rain and snow covered a large area from northwest to south of the Yangtze River. Cooling down At present, friends should be more graceful and temperature-oriented. When cotton trousers should be on the upper body, how much can they wear!

It should also be noted that in addition to cooling down, everyone should pay more attention to the large-scale rain and snow this week. Among them, the snowfall concentration period is 24-25 and 27 days. It is estimated that the dividing line between rain and snow on the 24th is located in the northwest of Zhejiang, the south of Anhui, the middle of Hubei and the southwest of Shaanxi. On the 27th, the dividing line between rain and snow was further pressed southward to the areas of central Zhejiang, northwestern Jiangxi, southern Hunan and central Guizhou. According to the city forecast, Shanghai, Hangzhou, Changsha and other places may see snowfall.

In addition, this snowfall lasts for a long time, and the accumulated snowfall is large. The newly added snow depth is 8-25 cm, and the local area can reach more than 40 cm. Among them, Hubei, Anhui and Jiangsu have a high degree of overlap in two snowfall areas, so it is necessary to clear the snow in time to avoid the collapse of agricultural greenhouses and simple structures that may be caused by too much snow. Snow and ice may cause highways and airports in Shaanxi, Henan, Hubei, Anhui, Jiangsu and other places to be blocked. The public should pay attention to arranging travel plans in advance.

Strange! One-time payment is more expensive than mortgage.

In the consumption experience of ordinary people, one-time payment can often enjoy more benefits and discounts, and the higher the value, the more obvious the goods are.

  Recently, Hua Ge (a pseudonym) in Hangzhou was going to change a new car, so he went to a number of 4S stores to understand the market.

  However, the salesman’s reply made him indignant: he wanted to pay off the car in one lump sum, not only did he not enjoy more preferential treatment, but the actual car price was more expensive than the mortgage loan. What’s going on here?

If you want to pay in one lump sum, the price of the car will increase by 10 thousand instead.

  Hua Ge told Qianbao that his current car has been driving for more than ten years, so he wants to buy a new car and improve his quality of life, focusing on several well-known brands such as BMW, Mercedes-Benz, Audi and Volvo.

  "The price range is set between 250,000 yuan and 300,000 yuan." After listening to a friend’s advice, he decided to buy a car mainly for BMW X1 and Audi Q3.

  In an Audi 4S shop on Shaoxing Road, Hua Ge took a fancy to the basic version of Audi Q3. At that time, the salesperson of the 4S shop said that if the car was purchased by mortgage, the car price was 250,000 yuan, which was the landing price, including purchase tax, licensing service fee and vehicle insurance premium for the first year. There are two kinds of mortgages, one for three years and the other for five years. Customers can choose.

  "I’ll pay in one lump sum. Can the car price be cheaper?" Brother Hua asked directly according to common sense of consumption.

  "I suggest you still get a mortgage. If you don’t mortgage, the car price must be increased by at least10,000 yuan. " The salesperson’s reply suddenly made Brother Hua blindsided.

  In order to keep Hua Ge as a customer, the young man in charge of sales said that if he really wanted to buy it, he could apply for a cheaper price. But if you don’t mortgage, it is indispensable to increase the car price by 10 thousand yuan.

  In another Audi 4S store in the west of the city, the sales staff gave the basic version of Audi Q3 a price of more than 250,000 yuan, and also suggested that he buy a car by mortgage. "This 4S shop is even better. Listen to the tone of the sales staff. If you don’t mortgage, you may not sell me a car. In addition, if you are an employee of Ali and Huawei, you can buy a car for another 2,000 yuan cheaper. " Brother Hua said.

  On this day, Hua Ge visited seven or eight 4S stores in Hang Cheng, including BMW and Mercedes-Benz, and the result was similar: if you don’t mortgage, the car price will be more expensive.

Every 4S shop is promoting mortgage to buy a car.

  As a customer, Qianbao reporter also went to several 4S stores in Hangzhou for experience.

  On Shaoxing Road in Hangzhou, there are many 4S car shops. In a Mercedes-Benz 4S shop, a young man in charge of sales told reporters that the landing price of a dynamic SUV is 406,000 yuan, and it can be 2,000 yuan cheaper if you apply for a mortgage.

  "The interest rate of our mortgage car purchase is very low. A loan of 100,000 yuan is used for a two-year mortgage, and the interest rate is only 1.5%, which is the interest of 3,000 yuan, which is equivalent to spending a total of 1000 yuan on mortgage car purchase. " The young man said.

  In another BMW 4S store, the manufacturer’s guide price of an SUV is 436,800 yuan. "If you pay in one lump sum, you will enjoy a 91% discount; If you mortgage, you can enjoy a 10% discount, which is more than 4,300 yuan cheaper. " A salesperson named Bao said.

  The salesperson told reporters that in their 4S shop, the minimum mortgage amount is 120,000 yuan, and there is a minimum mortgage ratio requirement. The reporter took a fancy to this SUV, and the minimum amount of mortgage was 137,000 yuan. "If you mortgage for two years, the interest will be 7,100 yuan, MINUS the discount of 4,300 yuan, which is equivalent to paying more than 2,700 yuan in interest for two years."

  Later, the hourly journalist came to an Audi 4S shop. A salesperson surnamed Xu told reporters that the market guidance price (bare car price) of an Audi Q5 is 446,500 yuan, and the preferential price for one-time payment is 361,500 yuan, with a discount of 85,000 yuan; If you mortgage, the preferential price is 348,500 yuan, and the discount reaches 98,000 yuan, which is 13,000 yuan cheaper than the one-time payment!

  Xiao Xu said that if a one-time payment is made, the vehicle purchase tax will be 33,000 yuan because of the high car price; If you buy a car by mortgage, the car price is cheap, and the vehicle purchase tax is 32,000 yuan, which can save 1000 yuan.

Selling mortgages wants to establish contact with customers.

  Why is the one-time payment car more expensive? In the Mercedes-Benz 4S store, the young man in charge of sales explained to me that handling mortgage loans can increase the stickiness of customers and establish long-term contact with customers. "If it is a one-time payment, it has nothing to do with us after the customer’s car leaves."

  But his explanation is obviously unconvincing. Because all the personal information of customers is retained in the process of car purchase, it is easy for 4S stores to contact customers. For customers who have taken out mortgages, the agreement stipulates that some specific after-sales services must go to 4S stores, but this connection seems far-fetched.

  In the process of buying a car, Qianbao reporter found another problem. Although every 4S shop actively encourages customers to buy a car by mortgage, the interest rates of mortgage loans are quite different. For example, if the Mercedes-Benz 4S shop mortgages for two years, the annual interest rate is 1.5%; If the BMW 4S shop is mortgaged for two years, the annual interest rate is about 2.6%; The Audi 4S shop mortgage loan has an annual interest rate of 4.2%.

  The sales staff of Audi 4S store said: "If we apply for a mortgage, we can get a rebate from the bank. We compensate the rebate to the car price, which is still very cost-effective for customers. If there is no advantage in mortgage, there will not be so many people to apply for mortgage. "

  The sales staff of Mercedes-Benz 4S store said: "Manufacturers have requirements for us, such as the proportion of cars sold by mortgage should reach 50% to 60% of customers. We are also trying to complete the manufacturer’s task indicators. "

  Just like buying a house by mortgage, buying a car by mortgage can really alleviate the tight cash flow of many consumers when buying a car. However, Hua Ge, who mentioned earlier, believes that if the car price of a full car is higher than that of a mortgage car, it obviously does not conform to the market rules, and the bank will increase the burden on consumers while generating income.

Prevention of respiratory infectious diseases, vaccination guide is coming!

The following article comes from Suzhou CDC, and the author is Suzhou CDC.

Suzhou disease control.

Disease control institution

Suzhou CDC WeChat WeChat official account

In the cold winter.

Infectious diseases such as influenza and mycoplasma pneumonia are high.

To this end, Suzhou CDC released

Guidelines for vaccination of respiratory infectious diseases in high incidence period

Let’s watch it together!

?

flu

Influenza is an acute respiratory infectious disease caused by influenza virus, which is highly contagious, mainly spread by droplets, but also indirectly through contact with contaminated hands and daily necessities. People are generally susceptible. After infection, they will gain a certain degree of immunity to the same subtype, but there is no cross-immunity between different subtypes, so people can get sick repeatedly because of different subtypes of infection.

Vaccination of influenza vaccine every year is the most effective means to prevent influenza. Because the composition of influenza vaccine will change due to the different epidemic dominant strains in that year, it is necessary to vaccinate influenza vaccine every year.

According to the types of influenza virus strains, influenza vaccines are currently divided into trivalent and tetravalent.

The strains covered by trivalent influenza vaccine this year are: influenza A H1N1, influenza A H3N2 and influenza B Victoria; The tetravalent influenza vaccine contains more strains of Yamagata influenza virus B than trivalent influenza vaccine.

At present, the influenza vaccine in Suzhou is a non-immunization program vaccine, which is vaccinated by residents voluntarily at their own expense.

Influenza vaccine immunization program:

1. Adult trivalent and tetravalent inactivated influenza virus vaccine, the target of vaccination is people aged 3 years and above, with one dose;

2. Children’s trivalent and tetravalent inactivated influenza virus vaccine, the vaccination target is children aged 6-35 months, and 1 or 2 doses are inoculated according to the vaccine instructions of different manufacturers;

3. Live attenuated trivalent influenza vaccine, targeted at children and adolescents aged 36 months to 17 years, with one dose.

Pneumococcal disease

Streptococcus pneumoniae (Spn) is the main pathogen causing pneumonia, meningitis, bacteremia and other serious diseases in children, and it is also the common cause of acute otitis media and sinusitis.

Pneumococcus is often temporarily colonized in human nasopharynx, and infants are the main hosts, which are generally transmitted by respiratory droplets or caused by colonized bacteria.

WHO lists pneumococcal diseases as diseases requiring "extremely high priority" for vaccine prevention. At present, the pneumococcal vaccines approved for marketing in China are divided into 13-valent pneumococcal polysaccharide conjugate vaccine (PCV13) and 23-valent pneumococcal polysaccharide vaccine (PPV23).

PCV13

At present, there are three kinds of PCV13 listed in China, all of which are suitable for infants and children aged 6-5 (before their 6th birthday). Specific vaccination procedures are as follows:

PPV23

PPV23 is used for people over 2 years old with increased risk of pneumococcal infection and pneumococcal diseases, especially but not limited to the following key populations:

① the elderly population;

② Individuals with chronic cardiovascular diseases (including congestive heart failure and cardiomyopathy), chronic lung diseases (including chronic obstructive pulmonary disease and emphysema) or diabetes;

③ Individuals suffering from alcoholism, chronic liver diseases (including cirrhosis) and cerebrospinal fluid leakage;

④ Functional or anatomical individuals without spleen;

⑤ People with impaired immune function (including HIV-infected people, leukemia, lymphoma, Hodgkin’s disease, multiple myeloma, common malignant tumors, patients with chronic renal failure or nephrotic syndrome), patients with immunosuppressive therapy (including corticosteroids) and patients with organ or bone marrow transplantation.

Usually, only one dose should be inoculated to the target. For those who need multiple cropping, they should be inoculated according to the instructions, and the interval of multiple cropping should be at least 5 years.

In order to implement the "531" action plan of Suzhou Healthy City, implement major infectious disease prevention and control projects, further reduce the incidence of pneumococcal pneumonia among the elderly in this city, and reduce the disease burden caused by the disease, Suzhou City has implemented free vaccination of 23-valent pneumococcal polysaccharide vaccine for the elderly over 65 years old in the city since April 2018. During the implementation of the project, every eligible elderly person can enjoy a free vaccination.

Mumps, measles and rubella

01

epidemic parotitis

Mumps is an acute respiratory infectious disease caused by mumps virus, which is more common in children and adolescents, but also in adults. It occurs in winter and spring, and it is easy to break out in schools, nurseries, kindergartens and other places where children are concentrated.

02

measles

Measles is caused by measles virus, which is highly contagious, and human beings are generally susceptible to measles virus. Patients are the only source of infection and spread from person to person through respiratory droplets.

03

rubella

Rubella is caused by rubella virus and is highly contagious. Rubella patients are the source of rubella infection and spread through respiratory droplets. Typical rubella has a pink mottled rash, which is easy to distinguish from measles with patchy dark red spots and papules. The mother suffers from rubella during pregnancy, and the virus can invade the fetus through the placenta, which may lead to fetal malformation, premature delivery, abortion and other dangers.

Vaccination with measles vaccine (MMR) is an effective means to prevent the above three infectious diseases.

Suzhou is currently carrying out the work of leak detection and replanting of vaccines containing measles components. Children aged 8-17 months who have not been vaccinated with measles vaccine, and children aged 18 months -18 years who have not been vaccinated with measles vaccine for 2 doses, all children who have no contraindications for vaccination with measles vaccine are the recipients.

In addition, in order to improve the level of protective antibodies against measles and rubella among teenagers, reduce the incidence of measles and rubella among the target population in adulthood, and reduce the risk of neonatal congenital rubella syndrome caused by rubella infection in women’s reproductive stage, Suzhou City has included the enhanced immunization program of measles and rubella vaccine for junior middle school students in local immunization plans, and all junior middle school students who are in good health and have no contraindications to measles and rubella vaccine can receive a dose of measles and rubella vaccine for free.

chickenpox

Chickenpox is a common infectious disease in children caused by varicella-zoster virus infection. Chickenpox patients are the only source of infection, mainly through respiratory droplets and direct contact.

The disease is highly contagious and people are generally susceptible to chickenpox. Persistent immunity can be obtained after illness, and it is rare to get chickenpox again, but herpes zoster can occur repeatedly. This disease can occur all year round, with the peak in winter and spring.

Vaccination program for varicella:

Vaccination with varicella vaccine is the most economical and effective means to control the spread of varicella.

Since January 1, 2023, Jiangsu Province has included live attenuated varicella vaccine in children’s immunization program, and school-age children can receive two doses of live attenuated varicella vaccine free of charge.

Immunization procedures are: the first dose for 12-18 months old, the second dose for 4-year-old children, and the interval between the two doses is not less than 3 months.

epidemic cerebrospinal meningitis

Epidemic cerebrospinal meningitis is purulent meningitis caused by meningococcus, which is a very dangerous acute respiratory infectious disease.

The high incidence season of epidemic cerebrospinal meningitis in China is in winter and spring. Man is the only host of meningococcus, which is spread by droplets or respiratory secretions. Carriers and patients are the main sources of infection. The population is generally susceptible, and the infection rate is the highest among children under 5 years old, especially infants from 6 months to 2 years old.

At present, there are five groups of meningococci causing human diseases: group A, group B, group C, group Y and group W135. The preventable groups of vaccines containing epidemic cerebrospinal meningitis in China are group A, group C, group Y and group W135.

Vaccination program for epidemic cerebrospinal meningitis:

According to the vaccination program of the national expanded immunization program, children aged 6 and 9 months were vaccinated with group A meningococcal polysaccharide vaccine, and A+C meningococcal polysaccharide vaccine was strengthened when they were 3 and 6 years old.

In addition, there are self-funded vaccines containing meningococcal components, including AC conjugate vaccine, AC-b combined vaccine of Haemophilus influenzae (AC-Hib combined vaccine) and ACYW135 group meningococcal polysaccharide vaccine.

Haemophilus influenzae type b

Haemophilus influenzae type B (Hib for short) can cause serious diseases in children, such as meningitis, pneumonia, septicemia, cellulitis, pericarditis and osteomyelitis. Hib can be colonized in human nasopharynx, and carriers are the main source of infection, mainly transmitted by droplets. More than 90% of cases of invasive Hib disease occur in children under 5 years old.

Hib immunization program:

In the Hib Vaccine Position Paper published by WHO, since serious Hib diseases mainly occur in children aged 4-18 months, they should be vaccinated as early as 6 weeks after birth.

Hib vaccine is a non-immunization program vaccine, and it is vaccinated according to the principle of voluntary, self-funded and informed consent.

At present, the vaccines containing Hib ingredients approved for marketing in China include: Hib conjugate vaccine, acellular DTP Hib conjugate vaccine (quadruple vaccine), adsorbed acellular DTP inactivated polio and Hib conjugate vaccine (quintuple vaccine), and AC meningococcal (conjugate) Hib conjugate vaccine (meningococcal AC-Hib conjugate vaccine).

(1) Hib conjugate vaccine

(1) Infants under 6 months old: from 2 months old or 3 months old, once every 1 month or 2 months, for 3 times in total. At the age of 18 months, one more booster immunization can be given.

(2) Infants aged 6-12 months: once every 1 month or 2 months, twice in total. At the age of 18 months, one more booster immunization can be given.

(3) Children aged 1-5: Only once.

(2) Quadruple vaccine

Three doses of basic immunization were given at the age of 3, 4 and 5 months; One dose of booster immunization was given at the age of 18-24 months.

(3) Five vaccines

Three doses of basic immunization were given at the age of 2, 3 and 4 months or 3, 4 and 5 months; One dose of booster immunization was given at the age of 18 months.

(4) meningococcal AC-Hib combined vaccine

(1) Vaccination begins at the age of 2-5 months, and a total of 3 doses are required, with an interval of 1 month for each dose;

(2) Vaccination begins at the age of 6-11 months, and a total of 2 doses are required, with an interval of 1 month for each dose;

People’s Forum Online Review | Let the grassroots cadres go into battle lightly.

  Recently, General Secretary of the Supreme Leader stressed during his inspection tour in Chongqing: "Continue to deepen the rectification of formalism to reduce the burden on grassroots and create favorable conditions for grassroots cadres and officers to start businesses." Since the General Office of the Central Committee of the CPC issued the Notice on Solving Prominent Formalism Problems to Reduce the Burden for Grassroots Units, various regions and departments have made continuous efforts to solve a number of outstanding problems. Grass-roots cadres are at the end of social governance. Only by clarifying the boundaries of powers and responsibilities, improving the mechanism of reducing burdens, and cultivating grassroots talents can the majority of grassroots cadres go into battle lightly, display their fists and feet, and really spend their energy on doing practical things.

  To "delimit" the responsibility and authority, forgrass rootscadreminusNegative.It is necessary to strengthen the management of the list of powers and responsibilities. First, the list of powers and responsibilities of the higher authorities about the grass-roots work, and clarify which work of this department should be participated by the grass-roots; The second is the list of work scope of grass-roots units, which determines the responsibilities that grass-roots units should undertake. People should do things according to their responsibilities and things should be done according to the system. By strengthening the management of power and responsibility list, standardizing and optimizing the scope of authority, all parties have clear responsibilities and do their best, so that the grassroots are no longer the "takers" of various responsibilities and matters, so that grassroots cadres can spread their shoulders and have more time to walk the streets and serve the masses.

  giveInstitutional mechanism "empowerment",forgrass rootscadreminusPress.It is necessary to work hard to establish a long-term mechanism, improve and perfect the work mechanism of burden reduction, which is coordinated from top to bottom, left and right, and coordinated by departments, and highlight the role of functional departments such as organization department, discipline inspection commission, and editorial office to form a joint effort to reduce burdens. Make good use of this family heirloom, go to the grassroots to find out the reality, understand the worries and difficulties of grassroots cadres, and solidify the mature experience and effective measures that meet the expectations and needs of grassroots in the process of burden reduction to form a long-term mechanism for grassroots cadres to learn from.

  Pave the way for growth and talent, and reduce worries for grassroots cadres..It is necessary to optimize the assessment and evaluation system, ensure that the index setting is focused on the grassroots, scientific and reasonable, promote the transformation from "quantity examination" to "quality examination", and truly play the role of assessment "baton". It is necessary to activate the "spirit" of cadres, motivate cadres with their careers, and send a group of grassroots cadres to major reforms, important positions and key projects to overcome difficulties, so that grassroots cadres who want to be officers, can be officers and succeed can stand out. It is necessary to implement the fault-tolerant and error-correcting mechanism, strictly implement the "three distinctions", comprehensively analyze the mistakes of cadres, boldly tolerate the fault-tolerant ones according to the procedures, and earnestly take responsibility for the cadres who dare to take responsibility and be responsible for the cadres who dare to take responsibility.

  In short, only by establishing a clear orientation of reducing the burden on the grassroots and supporting the hard work can we really activate the "one pool of spring water" for grassroots cadres to perform their duties conscientiously and actively, so that grassroots cadres can spend their time and energy on the "cutting edge" and exchange more hard work for the people’s happiness, sense of acquisition and sense of security.

After charging for 15 minutes, the electric car will get rid of the "charging anxiety" after driving for 300 kilometers.

  Our reporter Cao Xiuying

  "Charging anxiety" and "mileage anxiety" are a major obstacle to the large-scale industrialization of pure electric vehicles. At the 2019 World New Energy Vehicle Conference held recently, a technology called "High Specific Energy Fast Charging Lithium-ion Battery" won the Global New Energy Vehicle Innovation Technology Award.

  This technology breaks through the technical bottleneck that graphite system can’t charge quickly. On the basis of maintaining the advantages of high energy density, high safety and long life, it can complete 100% charging within 15 minutes, ensuring the cruising range of electric vehicles of 300 kilometers.

  What is the secret of this technology? How can we realize the fast charging of electric vehicles and make new energy users feel the convenience of "charging for five minutes and talking for two hours" like mobile phones?

  At present, the fast charging methods in the industry have disadvantages.

  As we all know, for pure electric vehicles, the charging and discharging performance of battery system is an important index to determine the actual use effect of vehicles. High energy density and fast charging ability are not only the technical direction that power battery manufacturers are constantly striving to develop, but also the core field of new energy technology.

  "Lithium-ion batteries are also called rocking chair batteries." Cheng Xiaoyan, director of scientific research project of Contemporary Amperex Technology Co., Limited New Energy Technology Co., Ltd. (hereinafter referred to as Contemporary Amperex Technology Co., Limited), told the Science and Technology Daily reporter that the two ends of the rocking chair are the two poles of the battery, and lithium ions run back and forth at both ends of the rocking chair. When charging, lithium ions move from the positive electrode of the battery to the negative electrode through the electrolyte. Graphite, as a negative electrode, has a layered structure, and lithium ions are embedded into the graphite through the interlayer. The more lithium ions are embedded, the higher the charging capacity is.

  A key index to measure the charging efficiency of electric vehicles is the charge-discharge ratio (C). The rate of charge and discharge can be simply understood as the rate of charge and discharge. The charge and discharge rate of lithium-ion battery determines how fast we can store a certain amount of energy in the battery or how fast we can release the energy in the battery. For example, when a battery with rated capacity of 100 A is discharged with 20 A, its discharge rate is 0.2C, and the used capacity is discharged within 1 hour, which is called 1C discharge; After 5 hours of discharge, it is called 0.2C discharge.

  It is generally believed in the industry that fast charging of electric vehicles refers to the charging method with a charging rate greater than 1.6C, that is, the technology that takes less than 30 minutes from 0% charging to 80% charging.

  As the name implies, to shorten the charging time, it is necessary to continuously improve the charging and discharging rate. The core of fast charging technology is to accelerate the speed of lithium ion moving between positive and negative electrodes through chemical system and design optimization. However, it is not enough to consider speed when developing fast charging technology.

  During fast charging, lithium ions need to be embedded into the negative electrode instantaneously. This is a great challenge to the ability of the negative electrode to receive lithium ions quickly. In the battery of common chemical system, lithium and other by-products will appear in the negative electrode during fast charging, which will affect the cycle and stability of the battery core. Only negative electrode materials that can withstand fast charging and high current can be used to achieve fast charging.

  Cheng Xiaoyan said that at present, lithium titanate and amorphous carbon are widely used as negative active materials in order to realize fast charging. However, both lithium titanate and amorphous carbon inevitably have the defects of serious shortage of energy density and high cost in practical application. The conventional design of increasing the amount of conductive materials will also affect the energy density of batteries. "In recent years, some manufacturers have begun to explore graphite as an active material, but the problem faced by graphite as a fast charging material is how to quickly release lithium electrons from the anode and then quickly enter from the cathode."

  Cheng Xiaoyan explained that graphite is more like a highway. Although the energy density is higher, lithium electrons can only pass through in sequence.

  In other words, graphite is not a natural material suitable for fast charging technology. "But we use technology to break through the bottleneck of the material itself, and its killer is ‘ Fast ion ring ’ And ‘ Superelectronic network ’ 。” Cheng Xiaoyan sighed.

  The fast ion ring and the super-electron net accelerate the charging.

  "We use graphite as the main material of the negative electrode, and innovatively use channel optimization and ‘ Fast ion ring ’ Technology, to create a circle of high-speed channels on the surface of graphite, so that lithium ions can be quickly embedded in any position of graphite, which greatly improves the embedding speed of lithium ions in the graphite cathode. Moreover, the modified graphite has the characteristics of super fast charging and high energy density, and there will be no by-products at the cathode during fast charging, which will affect the cycle and stability of the battery. " Cheng Xiaoyan said.

  In addition, the technical team developed the "super-electronic net" technology to modify the cathode material, and combined with the crystal orientation and capacity excess coefficient of the anode and cathode plates to optimize the dynamic properties of the electrolyte and anode and cathode, so that the chemical system and battery design parameters can be optimally matched.

  "Generally speaking, ‘ Fast ion ring ’ And ‘ Superelectronic network ’ It acts on the cathode and anode respectively, establishing a fast channel for a large number of lithium ions to flood into the cathode at the same time, and improving the diffusion rate of lithium ions. " Cheng Xiaoyan said.

  In addition, in terms of mechanical parts design, the team creatively simplified the design of the battery cell top cover, set the electrode terminals to the side of the top cover plate and reduced the terminal thickness, significantly reduced the internal resistance, effectively controlled the heat generation of fast charging, and ensured the reliability of fast charging while improving the energy density by more than 5%.

  "Our fast charging technology has 4C— 5C fast charging capability, achieving 10-mdash; 15-minute fast charging, compared with the fast charging system of lithium titanate cathode, has obvious energy density and cost advantages, and compared with other fast charging technologies in the industry which also use graphite as cathode, it can increase by 20%— 30% charging speed, and better cycle and weather resistance. " Cheng Xiaoyan said.

  It has been successfully applied to more than 5000 buses.

  At present, the super lithium-iron fast-charging battery developed by Contemporary Amperex Technology Co., Limited with fast-charging graphite as the main negative material has been applied to more than 5,000 electric buses, and the buses are in good running condition, which has been well received by vehicle manufacturers and bus users, and the battery has also been rated as "the best word-of-mouth battery for new energy buses" by the Ministry of Communications.

  In addition to its energy density, the battery has a great advantage. In terms of cycle life, taking buses with harsh application conditions as an example, it is fully charged and discharged about twice a day on average. Roughly speaking, it can meet the operating requirements for 8 years, and the battery needs more than 5,600 cycles. The cycle life of super lithium iron battery cells can reach 10,000 times, which not only fully meets the operating needs of electric vehicles, but also can be used for energy storage and other cascade utilization after retirement, creating more economic value.

  "In order to ensure the safety and reliability of the fast charging core, we have also developed special technology to identify the ‘ of the chemical system at different temperatures and SOC states. Healthy charging interval ’ , and then in this ‘ Healthy charging interval ’ Fast charging within the range can not only achieve fast charging, but also prevent the battery from being damaged by fast charging, so as to achieve fast charging, long cycle and safety and reliability. " Cheng Xiaoyan said.

  In terms of weather resistance, in order to meet the requirements of low-temperature charging in northern winter and high-temperature working conditions in southern summer, the technical team specially developed an efficient thermal management system to ensure that the battery is in a reasonable temperature range. The battery core can be heated quickly at low temperature, and the fast charging mode can be started when the temperature meets the requirements; At high temperature, the system will cool down the battery, and truly achieve "all-weather" fast charging.

  "We are developing 2C— with monomer energy density greater than 160 WHr per kilogram; 2.5C fast-charging lithium iron battery with high energy density and long life (more than 6000 cycles) is expected to be mass-produced by the end of 2019. At the same time, this technology has been applied and developed to the ternary system passenger car, which has achieved 350 kilometers of battery life and completed charging within 15 minutes. " Cheng Xiaoyan said that the company also plans to be in the next 1-mdash; Within two years, the ternary power battery product with energy density as high as 255 watt-hours per kilogram will be launched, which can be quickly charged within 18 minutes.
