CCTV News:The 10th China Conference on Chronic Diseases Management closed yesterday (15th). The reporter learned from the conference that the threat of chronic non-communicable diseases to human beings is becoming more and more serious. According to the statistics of the World Health Organization in 2018, the number of deaths caused by chronic diseases in the world is about 41 million every year, and the situation of prevention and control of chronic diseases in China is not optimistic, and chronic diseases have become the number one killer endangering national health.

　　　　　　 Wang Chen, dean of Peking Union Medical College, China Academy of Medical Sciences, said: "Chronic diseases are short for chronic non-communicable diseases, and the World Health Organization calls them four chronic diseases, namely cardiovascular and cerebrovascular diseases, tumors, chronic respiratory diseases, diabetes and metabolic diseases. Internationally, chronic diseases account for 87% of human deaths, and China accounts for 86%, which means that 86% of Chinese’s deaths are caused by chronic diseases. "

　　　　　　 According to experts, chronic non-communicable diseases are related to overweight, obesity, long-term overeating, insufficient exercise, nutritional imbalance, smoking and drinking, viral infection, autoimmune and other factors. Mental stress and emotional depression are often easy to cause a variety of chronic diseases, which are often ignored by people because of their own characteristics, which is also the main cloud cause of high incidence of chronic diseases in recent years.

　　　　　　 Wang Chen: "It doesn’t happen immediately after infection, like infectious diseases, so it makes patients suffer invisibly and unconsciously, which is an important feature of chronic disease." The more so, the more it deserves our attention in our daily life, and it is extremely prominent and important for China people to correct their bad habits. "

　　　　　　 Experts say that chronic diseases are treated in hospitals and prevented in individuals. At present, it is the focus of chronic disease prevention and treatment in China to guide people to seek medical treatment scientifically, use drugs rationally and change their lifestyle. Experts say that the treatment of chronic diseases is a systematic project, and scientific medical treatment and rational drug use are an important link in the treatment of chronic diseases.

　　　　　　 Weng Jianping, Executive Dean of School of Clinical Medicine, China University of Science and Technology: "It may be a combination of many diseases. For example, a person may have hypertension, hyperlipidemia, diabetes and other mental health diseases at the same time, so it is very necessary for doctors to identify the characteristics and problems of this patient, including the causes."

　　　　　　 Experts suggest that chronic diseases, as a kind of diseases coexisting with living habits, and their related risk factors are common in the population. Therefore, developing a healthy lifestyle is the focus of prevention and control of chronic diseases.

　　　　　　 Weng Jianping, Executive Dean of School of Clinical Medicine, China University of Science and Technology, said: "For ordinary people or most people, if they have no genetic background, I believe that a healthy lifestyle, including proper exercise and light diet, with less salt and less oil, is the most basic thing to do. In particular, the education and improvement of young people’s lifestyles and working methods is one of the most important, effective and direct factors to prevent chronic diseases. "

　　　　　　 Research shows that mental health problems will increase the risk of chronic diseases, and effective psychological intervention is not only an effective means to prevent and control chronic diseases, but also plays a positive role in the rehabilitation of patients.

　　　　　　 Studies have shown that serious mental health problems can induce a variety of chronic diseases. In China, 16%-17.5% of adults suffer from depression, but most people with mental disorders never seek help from mental health or psychologists, thus increasing the risk of chronic diseases.

　　　　　　 Peng Kaiping, Dean of Tsinghua University Academy of Social Sciences, said: "If our mentality is not good, long-term stress, long-term depression and anxiety can all cause cardiovascular diseases and endocrine disorders, and our various immune systems will be hurt, including our gastrointestinal problems, including our sleep, pregnancy, emotional activities, memory and actions."

　　　　　　 Studies have shown that 50-70% of patients with chronic diseases such as malignant tumors suffer from depression and 40-50% from anxiety, which not only destroys the normal physiological function of the body, but also causes emotional reactions such as pain, anxiety, depression, fear and despair, and even refuses treatment. So timely psychological intervention is particularly important.

　　　　　　 Zhang Minghui, director of the Institute of Cytology, Tsinghua University Clinical Medical College, said: "For some diseases that cause serious psychological problems, such as cancer patients, in addition to drug treatment or after drug intervention, we can create a relaxed and good living environment or working environment for them in time, which is very valuable for the rehabilitation of these chronic diseases. In modern medicine, we can use scales or modern testing to give an objective qualitative or evaluation."

　　　　　　 Experts point out that psychological intervention can help people with mental health problems get personalized help to cope with some health risks faced by their bodies and reduce the probability of chronic diseases.

At the press conference on epidemic prevention and control in Shanghai on the morning of April 27th, Shen Min, deputy director of Shanghai Civil Affairs Bureau, said that during the epidemic prevention and control period, the elderly, especially the very old, the elderly living alone, the sick and the disabled, will face more difficulties than ordinary people, such as lack of living materials, inability to take care of their children and inconvenience in seeking medical advice. Relevant departments and various districts, towns and villages have been taking measures to try their best to solve the problem. "But we also know that there are still places in the work that are not in place. The demands of some groups with special difficulties have not been discovered in time, and the response is not timely enough."

Shen Min said that the departments of civil affairs, health and wellness, commerce, and the Disabled Persons’ Federation have recently worked together to form work guidelines, further strengthening the care and protection for groups with special difficulties during the epidemic, and focusing on improving the following aspects:

One isImprove the mechanism of active discovery. First of all, it is required to fully rely on the original working mechanism, such as the community pension consultant in the civil affairs system, the "old partner plan" mechanism, the "one-button service for the elderly" platform in various districts, and the working system of the Disabled Persons’ Federation, etc., to comprehensively find out the actual needs of the elderly living alone, the recipients of pension service subsidies, the elderly with special difficulties who were left unattended because their families were isolated during the epidemic, and the people with special difficulties and disabilities who actually lived alone temporarily because their children’s relatives’ residences were blocked.

Shen Min said, in particular, we propose that we must dynamically grasp the needs of groups with special difficulties by establishing a real-time discovery mechanism. To this end, the hotline of the old-age service in each district was announced, and a special person was arranged to answer it 24 hours a day. In addition, actively promote the establishment of a volunteer team at the residential level to serve the special hardship groups in this residential area, collect the living needs of the special hardship groups in this residential area in time and give help. We hope that the district civil affairs bureaus and district disabled persons’ federations will establish a "list database of needs of special hardship groups" during the epidemic period through the above mechanism, so as to find out and respond in time.

The second isImprove the mechanism of resource allocation, and strive to implement the living security for groups with special difficulties. It is required to establish a platform for overall resource allocation through "special work classes" with towns as the hub (if towns have difficulties, they will be upgraded to the district level for overall planning). After finding out the needs of groups with special difficulties, towns will respond in time and solve related problems. For example, provide the distribution of general living materials for groups with special difficulties, allocate cruise taxis specially for going out for medical treatment, coordinate the catering and life care service resources at the street and town level, and deal with emergencies.

At the district level, establish a coordination mechanism for the living security of groups with special difficulties, specifically to solve the security needs that cannot be solved by towns and villages, especially some personalized materials in short supply, such as catheters and adult diapers, which are solved by all districts as a whole; For those that cannot be solved at the district level, it is clearly solved by large state-owned enterprises such as Bailian Group and Shanghai Pharmaceutical.

The third isImprove the mechanism of delivery to home. The basic living materials of the groups with special difficulties are distributed to the community by the towns and towns as a whole, and delivered to the door by the community neighborhood committees or volunteer teams. "Be sure to ensure the smooth delivery of the last 100 meters."

In addition, relying on the role of the volunteer team, help the special difficult groups to dispense drugs. Many districts have taken substantial actions, and some districts have formed a relatively complete working system.

　　Comparison of spike protein mutation between Delta strain and Omicron strain (picture from Rome Children’s Hospital)

　　■ On November 27th, local time, the research team of Rome Children’s Hospital released the world’s first picture of Omicron, a new mutant strain of Covid-19.

　　■ The picture shows that compared with Delta strain of COVID-19 mutant virus, Omicron strain has more spike protein mutations. These variations are diverse, and most of them are located in the areas that interact with human cells.

　　■ Researchers say that Covid-19 has adapted to the human body through mutation, but it doesn’t necessarily mean that it has become more dangerous.

　　The first case of Omicron virus infection occurred in Italy.

　　On November 27th, local time, Italy confirmed the first case of Covid-19 mutant strain Omicron infection by laboratory sequencing. Italy’s "Corriere della Serra" reported that the patient lived in Campania region in southern Italy and returned from a trip to Mozambique. He had previously tested positive for Covid-19 and was isolated, and now he is in good health.

　　On November 26th, local time, the Italian Ministry of Health has decided to ban people who have stayed in eight African countries including South Africa and Zimbabwe in the past 14 days.

　　Peter Hotz, a professor at Baylor Medical College in the United States, said: "We often lack mobility in the process of sequencing virus genes, so I wouldn’t be surprised at all if the new mutant has spread to the United States."

　　Where did the mutant strain come from?

　　Researchers are studying it.

　　With the spread of Omicron mutant, researchers are also studying where it came from. Franç ois Balu, a professor of biology at University College London, UK, said that Omicron mutant carries a series of unusual mutations, which may occur during the chronic infection of an immunocompromised patient or may come from an untreated AIDS patient.

　　Risk assessment of new mutant

　　More experimental data are still needed

　　Compared with Delta virus, where is the greater danger of the mutant strain "Omicron"? Will it trigger a wider spread?

　　According to Russian TV today, at present, Omicron mutant is spreading in Africa and outside Africa at an alarming rate.

　　Take South Africa as an example. Recently, 90% of the newly infected cases in gauteng province, South Africa are related to this mutant. Many western media believe that Omicron mutant is the most dangerous Covid-19 mutant in the world.

　　The researchers said that the Delta mutant strain discovered in India last October contained a total of 15 mutations, and the World Health Organization listed it as a "mutant strain that needs attention" in May this year; According to the preliminary study, the Omicron mutant, which is also listed as a "mutant that needs attention" by WHO, has more mutations than the Beta strain. At present, it is known that the mutant carries at least 32 mutations, which means that the effectiveness of the existing COVID-19 vaccine may be weakened and it may be more infectious.

　　WHO officials said that at present, little is known about this new mutant strain, and more experimental data are still needed to evaluate whether it is more infectious or more resistant to vaccines.

　　Who asks countries

　　Strengthen monitoring and sequencing.

　　How to prevent and control the new Covid-19 mutant? At present, the World Health Organization has asked countries to strengthen the monitoring and sequencing work, and called on countries to strengthen the monitoring and sequencing of all COVID-19 mutant strains that are still prevalent, submit the complete virus genome sequence and metadata to the public database, and report to WHO the initial cases or case clusters related to any mutant strains that need attention.

　　WHO also suggested that international cooperation should be carried out to better understand the various impacts of the mutant strains that need attention through field investigation and laboratory evaluation.

　　At the same time, some countries are worried that this new mutant strain will trigger a new wave of fierce epidemic after the Delta strain. Up to now, about 20 countries have issued or are preparing to issue entry restrictions for flights and passengers in southern African countries.

　　Foch/

　　Omicron strain

　　Or has existed in the United States and has not yet been discovered.

　　According to a report by CNN on November 27th, local time, Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said that Covid-19 mutant strain Omicron may have appeared in the United States, but it has not been discovered.

　　The U.S. Centers for Disease Control and Prevention said on November 26th that so far, no known cases of Omicron strain infection have been found in the United States. If the mutated strain appears in the United States, the U.S. Centers for Disease Control and Prevention expects to quickly confirm the cases through the monitoring system.

　　US President Biden announced on November 26th that the United States would restrict the entry of tourists from South Africa, Botswana, Zimbabwe, Namibia, Lesotho, Swaziland, Mozambique and Malawi from November 29th.

　　Influenced by Omicron strain.

　　The US government advised people not to travel to eight African countries.

　　On November 27th, local time, affected by Covid-19 mutant strain Omicron, the Centers for Disease Control and Prevention (CDC) upgraded the travel risk index of eight African countries, namely South Africa, Zimbabwe, Namibia, Mozambique, Malawi, Lesotho, Swaziland and Botswana, to "level 4", which means "very high".

　　On the same day, the State Council also issued a warning to the public, suggesting not to travel to the above eight African countries.

　　Zhong Nanshan, Zhang Wenhong and Wu Zunyou voiced/

　　Omicron strain poses more challenges to epidemic prevention.

　　According to the Southern Plus, Zhong Nanshan introduced in an interview on November 28th that from the current situation, the Omicron mutant has spread rapidly, and it has been popular in South Africa and other regions, and cases have been found in Hong Kong, China recently. "This mutant is very new. Although molecular genetic testing has found that it has many changes in the receptor binding site, how harmful it is, how fast it will spread, whether it will make the disease more serious, and whether it needs to be targeted. Vaccine research and development depends on the situation. It is too early to draw conclusions. "

　　Zhong Nanshan said that it will take some time to judge the harmfulness of Omicron mutant, and we need to pay attention to it at any time, but we won’t take any big action yet. "There is also a need to pay more attention to the prevention and control of personnel from relevant places in South Africa."

　　Earlier, Zhong Nanshan also said on the 27th that there is not much knowledge about this variant virus, but this virus carries a lot of mutations, which also poses more challenges to epidemic prevention.

　　At noon on November 28th, Zhang Wenhong also issued a Weibo to respond to the influence of the new mutant strain. Zhang Wenhong said that it can be judged that the emergence of the mutant virus in South Africa is accidental, but it will take about two weeks to observe whether it will pose a threat to the current fragile population immunity.

　　According to the Beijing News, on November 28th, Wu Zunyou, chief epidemiologist of China Center for Disease Control and Prevention, said that the epidemic situation is the most serious in the world, mainly in Europe, and the prevalent strain this winter and next spring is mainly Delta. Whether the mutant strain Omicron can develop into the dominant strain needs further close observation.

　　Wu Zunyou said that Omicron, a mutant strain discovered in South Africa, is a new mutant strain, with more mutation sites than the previous ones, reaching 32 mutation sites. The mathematical model shows that Omicron is more contagious than the Bedelta, but no matter how it mutates, public health measures such as wearing masks and keeping social distance are effective for all mutated strains.

　　(Comprehensive Xinhuanet, national business daily)

　　More than 20 countries have taken restrictive measures.

　　The discovery of Omicron strain in South Africa and other countries has aroused great global vigilance. Up to now, the governments of about 20 countries and regions have successively issued or prepared to issue entry restrictions for flights and passengers in southern African countries.

　　Among them, the British government said on the 26th that from that day on, flights from South Africa and five neighboring countries were prohibited from entering the country, and people with relevant travel history were required to undergo nucleic acid testing and isolation. On the same day, Switzerland announced that it would ban all direct flights from Botswana, South Africa and other countries indefinitely.

　　On November 26th, local time, the Italian Ministry of Health has decided to ban people who have stayed in eight African countries including South Africa and Zimbabwe in the past 14 days.

　　German disease control agencies have classified South Africa as a "virus mutation area", and all people who enter Germany from South Africa must be quarantined for 14 days, regardless of whether they have been vaccinated or not.

　　According to the notice issued by Pakistan National Command and Operation Center on November 27th, Pakistan issued a travel ban on passengers from South Africa, Lesotho, Swaziland, Mozambique, Botswana, Namibia and other regions.

　　In addition, Russia also announced that it will ban foreign citizens from South Africa and other countries and regions from the 28th of this month.

　　Health Canada also announced on 26th that it will ban foreign citizens who have been to southern African countries in the past 14 days.

　　Israel has banned its citizens from traveling to southern Africa after discovering new cases of mutant virus infection in its territory. On the 28th local time, Israel decided to ban all foreigners from entering the country, and the ban will last for 14 days.

　　Singapore and Malaysia announced on the 26th that they would ban the entry of passengers who have recently visited seven countries including South Africa.

　　The Indian government has issued a reminder, suggesting that local governments should carry out Covid-19 testing and health screening for international travelers from South Africa and other "risk zone" countries.

　　Japan has also implemented measures to ground inbound flights and isolate passengers for countries such as South Africa. In response to the travel ban issued by many countries around the world, the South African government responded on the 26th that it is harsh and unscientific to impose travel restrictions on passengers from South Africa, which is also inconsistent with the recommendations of WHO.

　　[rumor]

　　◎ Our reporter Chen Xi

　　In October, "all technology and hard work" became the hottest "stalk". The emergence of this hot spot has aroused people’s attention to food safety, and related rumors have also been widely spread, such as "sugar substitutes can be eaten openly" and "only zero addition is a good soy sauce" … … Rumors about the COVID-19 epidemic still appear from time to time, such as "scanning the code when going out in public places can avoid becoming a secret contact". In addition, the previous drought in some parts of China made the rumor that "precipitation can be artificially increased as long as there are clouds" spread widely.

　　Today, the reporter of Science and Technology Daily will take stock of the rumors that appeared in October one by one to help you clear the fog and find the truth.

　　Can sugar substitutes be eaten open?

　　Truth: Eating a lot of sugar substitutes also poses health risks.

　　With the approach of winter, people’s time for outdoor sports gradually decreases. Many people began to worry about insufficient calorie consumption, so they paid special attention to controlling calorie intake. Sugar substitute drinks and snacks marked "Zero Sugar" and "Zero Card" seem to contain no calories. Some people think that sugar substitute is healthy, so they don’t have to bear the "sweet burden" and can eat it openly. So, is this really the case?

　　"This view is wrong. Sugar substitutes should also be eaten reasonably, and there are also health risks when ingested in large quantities." Zheng Yunliang, director of Tianjin Institute of Modern Health Technology, said.

　　According to the data, sugar substitute refers to alternative sweeteners, which belong to food additives, and there are three main categories — — Natural sweeteners, sugar alcohols and artificial sweeteners. At present, most sugar substitutes on the market use artificial sweeteners, such as aspartame. This kind of sweetener does not exist in nature, but is synthesized by chemistry.

　　"From the perspective of energy production, sugar substitutes can be divided into nutritional and non-nutritional types. Almost all the decomposition products of non-nutritive sugar substitutes in human body do not contain glucose and do not directly participate in insulin secretion. Therefore, only in theory, non-nutritive sugar substitutes will not cause an increase in blood sugar. " Zheng Yunliang said.

　　However, this does not mean that we can eat sugar substitutes openly.

　　"The sweetness of sugar substitutes can stimulate appetite, and excessive intake may cause diarrhea, which may also increase the burden on the kidneys." Zheng Yunliang further said that with the progress of science and the deepening of research, most scientific research results show that artificial sweeteners may have pathogenic risks.

　　For example, on September 7, 2022, the British Medical Journal published a large-scale research result from France. This study shows that using artificial sweeteners instead of sugar in food or drink is not beneficial to the cardiovascular and cerebrovascular health of the whole population. Cell magazine also published a related study, which found that the intake of artificial sweeteners was related to the changes of intestinal microbiota and the increase of blood sugar.

　　Therefore, Zheng Yunliang suggested that consumers should try to choose foods containing natural sweeteners when choosing sugar substitutes, such as erythritol, stevioside, momordica grosvenori glycoside, sweet tea glycoside and so on.

　　"It is safe to eat food or drinks instead of sugar occasionally, so you don’t have to be overly nervous. The public should scientifically understand and eat sugar substitutes and improve their health through scientific and reasonable diet and exercise. " Zheng Yunliang said.

　　Can you avoid becoming a secret connector by scanning the code when you go out in public places?

　　Truth: Repeated code scanning will be considered as entering the place many times.

　　As a normal prevention and control measure of epidemic situation in COVID-19, scanning code before entering public places has been integrated into people’s daily life. However, a "special reminder" appeared in the WeChat circle of friends a few days ago: after scanning the code into a public place, scan the code again when leaving, and big data will "think" that you have gone out; If an infected person enters the site again, big data can "prove" that you and the infected person do not overlap in contact time, and you can avoid becoming close contacts.

　　In this regard, relevant departments in Shanghai, Shandong, Sichuan, Zhejiang, Fujian, Inner Mongolia, Liaoning and other places have all rumored. Experts from Dongying Big Data Center said that "place code" is a special two-dimensional code given to a place, which is used to identify the location, name and other information of the place and plays an important role in epidemic prevention and control in COVID-19. When someone scans the "place code", it can only show that they have been to the place. Using big data means can’t distinguish whether the person is in the "entry" or "departure" state.

　　In addition, relevant experts said that scanning the code twice may be considered as entering the place twice, which will not achieve the effect mentioned in the rumor, but will increase the workload of the flow control personnel and indirectly affect the epidemic prevention and control work. Experts reminded that the public only need to scan the code when entering the place, and there is no need to scan the code after going out. If the relevant staff find that the risk of infection of the code scanner is high, they will inform the code scanner in time and take prompt measures to avoid the spread of the virus.

　　Only zero addition is good soy sauce?

　　Truth: The quality of soy sauce depends on many factors.

　　Not long ago, the "additive" storm of a brand of soy sauce caused many consumers to talk about the color change of additives, so many people took the absence of additives as the standard for evaluating the quality of soy sauce.

　　"This statement is not entirely correct." Zheng Yunliang said that the so-called zero-added soy sauce is soy sauce with special color, fragrance and taste made by microbial fermentation without adding any monosodium glutamate or food additives. However, the quality of soy sauce depends on many factors, and zero addition is only one of them.

　　"First of all, the soy sauce listed should meet the relevant national standards." Zheng Yunliang introduced that China’s "National Standard for Food Safety Soy Sauce" (GB 2717-2018) stipulates that soy sauce is a liquid condiment with special color, fragrance and taste made from soybeans and/or defatted soybeans, wheat and/or wheat flour and/or wheat bran as the main raw materials through microbial fermentation. Soy sauce manufacturers shall have a complete fermentation and brewing process, and shall not use raw materials such as acid hydrolyzed vegetable protein seasoning liquid to produce soy sauce.

　　Soy sauce that meets the relevant national standards has reached the "passing line", but it is not high quality.

　　"Soluble solids, chloride, total nitrogen, total acid and reducing sugar in soy sauce are important quality evaluation indicators, which can affect the quality of soy sauce." Zheng Yunliang introduced that the umami taste of soy sauce depends on the content of amino acid nitrogen. Generally speaking, the higher the content of amino acid nitrogen, the higher the grade and the better the quality of soy sauce.

　　At the same time, as a traditional fermented condiment in China, the flavor of soy sauce is also an important quality index. The differences in koji varieties and technological processes of different soy sauces will make them have great differences in flavor.

　　According to related technical literature, 230 nonvolatile compounds were detected in soy sauce, including 90 peptides, 49 organic acids, 27 amino acids and their derivatives, 28 sugars, 11 sugar alcohols, 6 biogenic amines, 4 nucleotides and 16 other compounds, which determined the acidity, sweetness and concentration of soy sauce.

　　In addition, Zheng Yunliang reminded that consumers should also have a rational understanding of additives and not be overly superstitious about zero-added food.

　　"In soy sauce processing, the most commonly used food additives are sodium benzoate, disodium inosinate and disodium guanylate. Rational use of food additives can prevent bacterial growth, moderately extend the shelf life, and make soy sauce more cost-effective. " Zheng Yunliang said.

　　In fact, instead of paying attention to food additives, consumers should pay more attention to the sodium content in soy sauce.

　　"In every 100ml of soy sauce, the sodium content is about 6g, and the recommended intake of sodium is only 2g/day. Related studies have shown that excessive intake of sodium may lead to cardiovascular diseases such as hypertension and arteriosclerosis. " Zheng Yunliang reminded.

　　As long as there are clouds, it can artificially increase rainfall?

　　Truth: Certain conditions are needed, and the key is to have the right cloud.

　　Since this summer, the drought in the eastern part of southwest China, the south of the Yangtze River and the northern part of South China has continued to develop, and it has suffered from drought in summer and autumn. The water levels of Poyang Lake and Dongting Lake all hit record lows, and some lakes even became "deserts" and "grasslands". At the same time, there is a question on the internet: as long as there are clouds, artificial precipitation can be carried out. Why not carry out artificial precipitation enhancement in these arid areas?

　　In this regard, Wang Zhaoyu, director of the Tianjin Office of Weather Modification, said that artificial precipitation enhancement is not artificial rainfall, and "turning clouds into rain" requires certain conditions.

　　Artificial precipitation enhancement is to influence the microphysical process of clouds through artificial intervention under appropriate weather conditions, so as to increase the ground precipitation.

　　"The way of artificial intervention is mainly by sowing catalysts into the cloud. Generally speaking, the catalysts sown in the northern region are mostly silver iodide, while dry ice and liquid nitrogen are commonly used as artificial precipitation enhancement catalysts in the southern region. In addition to catalysts, there are ways of manual intervention, such as emitting femtosecond laser and charged particles to the cloud. " Wang Zhaoyu said that no matter which way is used, the ultimate goal is to form condensation nuclei, promote water vapor condensation, and finally form precipitation.

　　However, a clever woman can’t cook without rice. In this process, the most crucial thing is — — There should be a cloud that meets the conditions of artificial precipitation enhancement. Such a cloud needs to have a certain thickness, height and temperature, and at the same time, the water vapor in the cloud should be abundant and just in the updraft area.

　　Wang Zhaoyu explained that the medium and low clouds with a temperature of MINUS 10 to 0 degrees Celsius, a thickness of about 2,000 meters and a height of less than 6,000 meters are suitable for artificial precipitation enhancement. Such warm clouds are full of small water droplets, which float in the air and cannot fall down under the support of updraft, forming clouds; With the help of the catalyst, increasing the concentration of condensation nuclei in the cloud can make small water droplets collide more and more into large water droplets, and then form precipitation.

　　 H7N9 avian influenza is a new type of avian influenza, which was first discovered in Shanghai and Anhui at the end of March 2013. H7N9 avian influenza is a new subtype of influenza virus discovered for the first time in the world, which has not been included in China’s legal infectious disease monitoring and reporting system, and no vaccine has been launched until the beginning of April 2013. All patients infected by this virus have symptoms such as fever in the early stage. By April 2013, it has not been confirmed whether this virus has the characteristics of human-to-human transmission. In April, 2013, it was investigated that the gene of H7N9 avian influenza virus came from the gene rearrangement of wild birds in East Asia and chickens in Shanghai, China, Zhejiang and Jiangsu. The cases are distributed in Beijing, Shanghai, Jiangsu, Zhejiang, Anhui, Shandong, Henan, Taiwan Province, Fujian and other places.

　　H7N9 is a subtype of avian influenza. The outer membrane of influenza virus particles is covered by two types of surface glycoproteins, one is hemagglutinin (H) and the other is neuraminidase (N). H is divided into 15 subtypes and N is divided into 9 subtypes. All human influenza viruses can cause avian influenza, but not all avian influenza viruses can cause human influenza. Among avian influenza viruses, H3, H5, H7 and H9 can be transmitted to people, and H5 is highly pathogenic. H3 is a zoonotic disease. According to the characteristics of influenza virus, it can be divided into 135 subtypes of HxNx, and H7N9 subtype avian influenza virus is one of them. Previously, it was only found in birds, and no human infection was found. The biological characteristics, pathogenicity and transmission of the virus have not been analyzed and judged.　　　

　　Tips:

　　The incubation period of human infection with H7N9 avian influenza is generally less than 7 days. Patients usually show flu-like symptoms, such as fever, cough, less phlegm, which may be accompanied by headache, muscle aches and general malaise. Severe patients’ condition develops rapidly, showing severe pneumonia, with body temperature above 39℃ for the most part, and dyspnea, which may be accompanied by coughing up blood and phlegm; Acute respiratory distress syndrome, mediastinal emphysema, sepsis, shock, disturbance of consciousness, acute kidney injury and so on can rapidly progress.

Special feature of 1905 film network　　 The weekend of the 14th week of 2019 (from April 1st to April 7th) just covered this year’s Qingming small holiday, so the box office data in a single week increased significantly year-on-year, reaching 966 million, of which nearly 700 million were produced from 5th to 7th. The Chinese-language series "Anti-Corruption Storm 4" finally became this week’s champion, attracting 350 million yuan in four days, and the much-anticipated DC superhero "Thunder Shazan! It didn’t play much, and the box office just passed 200 million and ranked second.

Qingming file box office 690 million "Anti-Corruption 4" won the championship and Shazam was cold

The Qingming small holiday in 2019 is from April 5 to 7, so these three days on the weekend have also become the peak of box office output this week, reaching 690 million. Among the new films, the series of films "Anti-Corruption Storm 4" and "A Cloud Made of Rain in the Wind" starring Louis Koo took the lead in painting on the 4th. On the first day, the former easily climbed to the top with nearly 80 million box office. Obviously, this day also gave "Anti-Corruption Storm 4" time to spread word of mouth, and on the 5 th, "Thunder Shazan! After the opening of the painting, it once occupied the first place in the box office and film arrangement by virtue of the pre-sale advantage, but the last laugh that day was "Anti-Corruption Storm 4", and the film also achieved a single day of breaking 100 million. In the end, until the end of the holiday, Anti-Corruption Storm 4 continued to win the box office championship, which opened the box office gap with the second place, and accumulated 350 million yuan in four days.

On the other hand, "Thunder Shazan! As a DC superhero movie, the pre-sale results of the film are not very good, but 40% of the films still reflect the market’s expectations. However, due to the limitation of production style and IP influence, the film only took 200 million yuan during the three-day short holiday, which made DC feel cold again after Aquaman was proud.

Andhadhun’s word-of-mouth fermented Lou Ye’s new film has a low audience rating.

Indian films, once highly sought after in the mainland, finally moved again this week. Andhadhun, which focuses on brain-burning style, is known as "a reversal in 5 minutes", and its plot is thrilling and wonderful. After the release on the 3rd, the box office and word-of-mouth went up simultaneously. At present, the cumulative box office of the film is close to 100 million yuan, with Douban score of 8.3 and online sales platform score of 9.2, both the highest in the same period. Perhaps the success of Andhadhun can once again save the ups and downs of Indian films in the mainland market.

Compared with the liveliness of Andhadhun, Lou Ye’s topical work A Cloud Made of a Rain in the Wind, which came back from the Berlin Film Festival, is a bit much cry and little rain. Before the screening, all kinds of discussions around the film continued, including Lou Ye himself. Unfortunately, after the release, the film was not recognized by the audience, and the lowest score of the online sales platform has dropped to 6.9. Some critics think that the story of A Cloud Made of a Rain in the Wind is not solid enough as a suspense and crime film. However, in any case, the box office of the film has steadily exceeded 50 million in this small holiday, which is regarded as the commercial "success" of director Lou Ye.

Week 15: Guo Tao’s debut PK Faye Yu romance.

There will be no large-scale films coming into the mainland film market next week. Perhaps the most anticipated film is Guo Tao’s directorial debut "The Game of Desire". The film also focuses on the suspense plot of crime. I wonder if he can be as successful as Bo Huang and others in acting and guiding.

I care about you, which was changed once, also started painting this week. Faye Yu and Takao Osawa will perform beautiful love. I wonder if this Japanese-style romantic film can be successful?

A few days ago, Chezhi. com obtained a set of official maps of Tucki M03, the first model of MONA series, from Xpeng Motors. The new car adopted a brand-new design and kept the Tucki brand LOGO. It is reported that the new car will enter the market of 100,000-150,000 yuan in the future, and adopt Tucki’s intelligent driving technology.

In terms of appearance, the new car adopts a completely different design from Xpeng Motors. First, the headlights are Y-shaped, which has excellent visual effect and is highly recognizable. In addition, the front face is surrounded by a black front, which adds a lot of sportiness. It is worth mentioning that Tucki M03 still uses Xpeng Motors’s "X" logo, which shows that MONA is not a brand new brand, but a brand new series.

The side design is very simple, using the popular hidden door handle design. It is worth mentioning that there is a very creative small spoiler in the D-pillar area on the side of the new car, and its function has not been revealed yet. In addition, there is no lidar on the roof at present, and a pure vision scheme may be adopted in the future.

At the rear of the car, the new car also uses a Y-shaped taillight, which echoes the headlights. The interior of the taillight is also blackened, and the visual effect is good after lighting.

The interior and power system have not been announced yet. According to people familiar with the matter, the battery supplier of Tucki MONA’s first car includes BYD, and its battery life will exceed 500km. For more news about the new car, the car quality network will continue to pay attention to and report.

1905 movie network feature A year ago, we wrote a manuscript, "Laughing at Lu Han is the real tragedy of the year". At that time, the manuscript wrote: Failure does not mean that Lu Han should really be laughed at by the crowd. This film should be a warning that we allow failure, and failure is for future progress.

After the manuscript was sent out, various comments emerged in the background, some supporting their favorite beans, and some continuing to "black". Without a doubt, traffic largely represents controversy. As a representative of traffic, Lu Han’s every move will be noticed by the public. In the past year, in addition to publishing music works, he has participated in the recording of "Creation Camp 2020", and rarely participated in other film and television works. He is still surrounded by countless fans, and at the same time, many people are singing bad news.

Until the online drama "Crossing the Wire" went live, the comments about him, whether on Weibo and Zhihu, or on Hupu and Douban, formed a "epic" praise front.　

This time, maybe we can re-establish ourselves in the context of our work and talk about Luhan as an actor.　

Luhan is no longer exquisite.

At the beginning of the first episode of "Crossfire," we almost didn’t recognize Lu Han on the screen. With short instant noodle hair, a baggy T-shirt, fat pants, and flip-flops, he looked like a gamer.　

In this drama, he is no longer the shining idol image we used to know in front of the camera. He does not maintain the expression management of an idol at all times, nor does he have a Korean filter, but the audience is very comfortable watching. Lu Han said in an interview with "Shanghai Fortress" that I am learning about the word actor step by step, and I especially want to deeply study the acting aspect, because I am also gradually transforming, hoping to use my own actions to work hard to get more people’s recognition step by step.　

When the movie was released, his overly delicate and handsome appearance was constantly complained, and many viewers who did not buy it believed that his thick bangs did not match the role setting of the officer and lacked the toughness that should be there.　

Now, at least from the initial impression in "Crossfire", it can be seen that Lu Han and the entire team are really determined to transform. Of course, pretending to be ugly can never prove his acting skills, it can only be said that he has taken the first step.　

In the sixth episode of the series, Lu Han made his most emotional appearance as an actor. In order to comply with his parents’ arrangement and make his job regular as soon as possible, he kept changing drinks for the leader at the wine table. After three rounds of drinking, he returned home, sitting decadently on the ground, facing the dilemma of reality and dream.　

Sighing, bowing his head, and Lu Han’s habitual licking of his lips. This string of movements is placed here, directly conveying the helplessness and confusion of this character to the audience in a layered manner. Director Xu Hongyu mentioned in an interview that during the filming of this scene, Lu Han did not rely on drinking alcohol to find feelings, but actually performed it.

Let’s watch another scene. He was also full of enthusiasm. After running errands to buy KFC for the leader, he was finally thrown away by the other party. At this time, the camera still gave Xiao Feng a close-up – the same sigh and bow, but the emotion given was no longer helplessness, but the helplessness of "social animals" and the grievance of not daring to be angry.　

Let’s take a look at a group of the same scene and compare the states in different atmospheres. At the beginning, Xiao Feng temporarily put down his dream and stood at the door of the unit to pull his tie. It was a kind of helpless but had to be passively accepted.　

After this short period of work, he resigned decisively at the staff meeting, choosing to ignore the eyes and pressure of the world and resume his e-sports dream. Even at this time, he did not have any team members around him, but the youthful high spirits returned to him again.　

From these key scenes, Lu Han really grasped the different emotional states of Xiao Feng’s character. Overall, he still retained some habitual movements during the performance, but in this drama, these movements no longer seemed inconsistent, but could make people easily enter the play. This time, Lu Han did improve.　

Just a comfort zone?

On the Internet, they saw a lot of negative opinions. They thought that Lu Han had performed well this time, largely because Xiao Feng’s character was close to him. In other words, Xiao Feng was Lu Han performing in his comfort zone.

Looking back at his previous works, when he starred in and, many people said that the characters in these two works are similar, and they are more compatible with Lu Han himself, and there is not much personality arc, so it is not too difficult.　

So can these characters be hastily considered as Luhan in their comfort zone?

We don’t know, and I believe that no one except himself would dare to make such a positive conclusion. When Lu Han met the director Xu Hongyu for the first time, the first question he asked the other party was, "Do I want to play Lu Xiaobei?" Because in his opinion, this role is very similar to him and has a sense of security. This result was rejected by the director, but at that time he did not know whether the teenager in front of him could play the role of Xiao Feng well.　

For all the people behind "Crossfire", they were very sure that casting the star, who was a huge controversy in his acting at the time, in the role meant risks. Because before this, Lu Han’s first series "The Book of Choice" had just faced the double fire of word-of-mouth and business. During the filming of this drama, Lu Han chose to hand himself over to the director. During the five months of filming of the film, he hardly left the crew. He talked to the director every day to find the feeling of Xiao Feng. They started with the details of their lives, and wiped all the traces of the "idol Lu Han" in the eyes of everyone.　

Therefore, in "Crossing the Line of Fire", we can see a state of Luhan that we have never seen before, not playing handsome or deliberate, but really turning ourselves into Xiao Feng in the drama. There is a sentence on the poster of the characters in the drama, "In Crossing the Line of Fire, what do you want to leave behind?" Perhaps for Luhan, it is also a question that he should seriously consider as an actor.　

He once said in an interview, "I don’t think it’s possible to like everyone, as long as you work hard 100%, or 200%, or you feel that you have a breakthrough. Because it’s impossible to get everyone’s recognition, maybe some people’s doubts will become the driving force for your progress. I hope everyone can see my progress." This sentence just responded to the question on the poster. What he wanted to keep was his acting skills and everyone’s recognition.　

Transformation, stand up

In just 5 years from "Return to 20" to the present, the audience has witnessed every step of Lu Han. This year, Lu Han just turned 30 and officially entered his thirties. He knows very well that it is not just traffic that really needs to stand firm in this entertainment industry. Obviously, he has slowed down his progress because of this.　

He is facing his own transformation. On Lu Han’s Weibo certification, he says "actor, singer," but few people other than fans are willing to use "actor" to define his identity.　

While reconstructing his identity as an "actor" to the outside world with his actions, he is slowly making a transformation. He understands that he cannot always appear in film and television works as an idol or a teenager, and the same appearance will not bring recognition to everyone. As he said, "I am learning about the word actor step by step, and I especially want to deeply study the aspect of acting, because I am also gradually transforming, hoping to use my actions to work hard to get more people’s recognition step by step."

When everyone thought he could only play a certain type of role, he once said that he especially wanted to play the villain. Perhaps compared to the role of Xiao Feng in "Crossing the Wire", the villain will become his biggest challenge. And in the work "Doom" to be broadcast, he will try the villain role of Sven scum for the first time.　

For the audience, it will be another kind of expectation. Admittedly, at the end of this article, we are not trying to brag about how good Lu Han’s acting skills are, but objectively speaking, in "Crossing the Wire", he has obviously made qualitative progress. The public often looks at this group of stars with the colored lens of "traffic".

They may still be some distance away from the name of actors, but as for whether their acting skills are good or bad, whether they have improved or regressed, is the content worthy of public discussion. The concept put forward by Xu Hongyu during the creation of "Crossfire", "game life", is not a state of bottoming out immediately, but a process of exploration. This process requires time, recognition, and questioning, not pure denial.

As Gala’s performance of "Dreams of Innocence" sings in the latest episode, "Run forward/Face the cold eyes and ridicule/The vastness of life can’t feel without suffering/Fate can’t make us kneel and beg for mercy/Even if the blood is spilled in the arms."
