Stills of Chloe Bennet’s "Aegis Secret Service"

1905 movie network news Recently, some netizens found that Chloe Bennet’s MV "Tonight" starring in the popular group BIGBANG accidentally bumped into Dilraba, and many netizens said that "both of them have exquisite facial features and are indeed somewhat similar".

Chloe Bennet and Dilraba were both born in 1992. One is of mixed blood between China and the United States, and the other is of Uygur nationality. The same exotic customs make them have certain similarities in appearance.Chloe Bennet is a typical actress of European and American models, while Dilraba is a small flower of the new generation in China. In essence, their routes and development directions are different.

Comparison between Chloe Bennet and Dilraba

Chloe Bennet, a post-90s Chinese actress, won high popularity and attention for her role as the heroine "Shockwave Girl" Skye. Recently, some netizens launched the "Seven Goddess of Marvel Comics of the Year" selection campaign, and Skye, the "Shockwave Woman" played by Chloe Bennet, was on the list. Some netizens commented: "This super-powerful heroine that was missed has finally been discovered, and her strength really does not lose the black widow!" .

In the play, Chloe Bennet’s "Shobo Girl" is Nick Frey’s right-hand man. At the age of 18, she has the tenth security clearance of SHIELD. She is the only agent with this clearance except Frey and the Black Widow, and she is also the youngest agent in the history of SHIELD. Although in Marvel comics, Shobo Girl is a member of the reunion, but in the drama, Shobo Girl played by Chloe Bennet has become a substitute for the reunion.

Some netizens speculated that the Chinese actress born in the 1990s will return to China for development in the near future. Let’s wait and see!

There are many respiratory diseases in children in winter, among which influenza virus is one of the common pathogens. On the questions that parents and friends are concerned about, the National Children’s Medical Center Beijing Children’s Hospital answered authoritatively.

1. What are the typical symptoms of influenza?

Children infected with influenza virus can show fever, chills, headache, myalgia and general malaise, often accompanied by respiratory diseases such as cough, sore throat and runny nose. The degree of fever in young children may be heavier, and some children may also have febrile convulsions; In addition, they will have more gastrointestinal symptoms, such as nausea, vomiting, diarrhea and poor appetite. Very few children infected with influenza may develop into severe influenza, causing laryngitis, pneumonia, encephalopathy, myocarditis and so on.

2. How does the flu spread and how long is the incubation period?

Influenza virus can spread from person to person through respiratory droplets (such as sneezing, coughing and talking) or after polluting the surface of objects. Influenza viruses can also spread through small air particles released by influenza patients when they breathe. Influenza patients are the main source of infection. The incubation period of influenza is generally 1-7 days, and most of them are 2-4 days.

3. How long is the general course of influenza and what is the change of the course?

For children without basic diseases, the course of influenza virus infection is acute and self-limited, and most symptoms disappear in about 2-3 days after onset. Some children’s fever lasts for 5 days, and most patients recover within 1 week, but cough may last for a long time, and fatigue and fatigue of a few elderly children (over seven or eight years old) may last for several weeks.

4. How to distinguish the flu from the common cold?

The full name of the flu is called "influenza", and you may think it is similar to the common cold, but the flu and the common cold cannot be confused.

The common cold can be caused by many pathogens, among which viruses are the most common, including rhinovirus, adenovirus, metapneumovirus, bocavirus, etc. Bacteria and mycoplasma can also cause the common cold. The symptoms of the common cold are mild, usually low-to-moderate fever, which lasts for 1-2 days, and may be accompanied by other catarrhal symptoms such as sneezing, runny nose, stuffy nose and slight cough, while the systemic symptoms such as chills, headache and joint muscle pain are very mild. Generally, there are no serious complications.

Influenza is mainly caused by influenza A and B virus infection, with high fever, severe systemic symptoms such as chills, headache and joint muscle pain. A few influenza patients may have complications such as rhabdomyolysis, pneumonia, encephalitis and encephalopathy.

In the flu season, children with flu-like symptoms, especially those with a history of contact with influenza patients, should first consider influenza virus infection, which can be diagnosed by influenza virus antigen detection or influenza virus nucleic acid detection.

5. How is the flu generally treated?

After being infected with influenza virus, the treatment measures include antiviral and symptomatic treatment.

Anti-influenza drugs: At present, the oral antiviral drugs for influenza virus are mainly neuraminidase inhibitors, commonly used drugs include oseltamivir and mabaloxavir, and intravenous drugs include paramivir. Once you have the flu, the sooner you use anti-influenza drugs, the better, especially within 48 hours of onset. However, even if the course of the disease exceeds 48 hours, once the flu is confirmed, you should actively use drugs.

Symptomatic treatment measures: mainly to reduce fever and relieve discomfort. You can choose antipyretics scientifically, and you can also use some drugs to relieve symptoms such as cough and stuffy nose. It should be noted that the pharmaceutical ingredients of some compound preparations may overlap with other therapeutic drugs, and the combined use may cause an excessive amount of one ingredient and cause adverse reactions in children.

6. Is there any specific medicine for influenza and can it be prevented by drugs?

Oseltamivir is an antiviral drug specifically for influenza virus, which can shorten the duration of clinical symptoms. However, it is not recommended that children take anti-influenza drugs as soon as they have a fever, because there are many respiratory pathogens that cause fever, and oseltamivir is only effective for influenza.

The best way to prevent influenza virus is to actively vaccinate. If there is no contraindication, people over 6 months are advised to actively vaccinate against influenza. For children with high risk of severe influenza or influenza complications, who are contraindicated by influenza vaccine or have not been vaccinated (or within 2 weeks after vaccination), drug prevention should be considered. Drug prevention can reduce but not eliminate the risk of influenza, and the susceptibility to influenza will be restored after drug withdrawal. Therefore, routine drug prevention for children is not recommended.

7. Are azithromycin and other antibacterial drugs useful for influenza?

Antibacterials, including azithromycin, are ineffective against viral infection. However, if there is a mixed infection of influenza virus and bacteria or mycoplasma, doctors will also consider the use of anti-influenza drugs combined with antibacterial drugs.

8. Fever is one of the typical symptoms of children. What misunderstandings should be avoided in home care?

The main purpose of taking antipyretics for children is not to reduce the body temperature to normal, but to increase the comfort of children and let them spend the fever period comfortably and safely.

First of all, you can’t take two antipyretics at the same time, which will increase the burden on your child’s liver and kidney and cause adverse reactions; It is also not recommended to use the two antipyretics alternately, because it can not increase the antipyretic effect, but may mistake the time and even lead to overdose.

Secondly, when parents choose antipyretics for their children, they should not only choose drugs suitable for their age, but also read the instructions carefully, and give them to their children in strict accordance with the instructions, paying attention to the dosage and time interval. Remember not to increase the dosage or frequency at will because the child’s body temperature has not dropped to normal.

Finally, if you give your child a compound cold preparation at the same time, you must read the drug ingredient list to avoid duplication with other drugs being used, such as antipyretics. If there is duplication, please use it with caution to avoid overdose.

In daily life, children should be kept in a regular routine to ensure adequate sleep; In terms of diet, we should pay attention to nutrition, have a balanced diet, eat more fruits and vegetables and drink more water. At the same time, avoid the family environment being too dry and ensure the humidity, which is conducive to the recovery of children. Parents should also pay attention to the fact that children should neither cover up their fever nor let them catch cold again. Parents should maintain a peaceful attitude, pay attention to their children’s fever, and don’t be overly anxious, carefully observe their children’s situation and help them recover as soon as possible.

9. I am particularly worried about my child’s febrile convulsion. What should I do if there is febrile convulsion?

If the child has a febrile convulsion, parents must keep calm and don’t panic: (1) Let the child lie on his side or tilt his head to one side, and clean up things with sharp corners around him to ensure that the child will not be hurt when the convulsion occurs. (2) When convulsions occur, don’t stuff anything into the child’s mouth, and don’t feed anything, and don’t try to stop twitching by pressing the limbs. (3) Record the duration and seizure characteristics of convulsions. If the duration of convulsions exceeds 5 minutes or the status quo of convulsions has occurred in the past, call an ambulance. In most cases, febrile convulsions will stop within 5 minutes.

10. What happens that requires timely medical treatment?

Most children with influenza are mild patients, so they can take care of them at home. However, if the following situations occur, they should seek medical attention in time: children who have been diagnosed with influenza have high fever or fever for more than three days, poor mental health or even consciousness disorder, shortness of breath/dyspnea, chest pain, blue skin on the lips, frequent vomiting or diarrhea, convulsions, refusal to eat, scanty urine or urine turning red, and obvious muscle pain; Or if the symptoms are repeated, such as fever again after the flu symptoms are relieved, you need to seek medical advice in time to avoid aggravation and even danger.

11. Which children are at high risk of severe influenza?

High-risk children with severe influenza include: children under 5 years old, especially children under 2 years old; There are basic diseases, such as asthma, tumor, kidney disease, immunodeficiency, taking immunosuppressive drugs, etc.; Obese children are also high-risk groups. When high-risk people have fever during the influenza epidemic season, they should attach great importance to it and seek medical treatment as soon as possible. Once influenza virus infection is considered, antiviral treatment should be started as soon as possible. If there are no contraindications, people at high risk of severe influenza should be actively vaccinated before the flu season begins.

12. Will you get the flu if you are infected with mycoplasma pneumonia recently?

I will. Because the body’s resistance will decrease when it is infected, it may be easy to be infected with other pathogens. Measures to prevent cross-infection include paying attention to self-protection, trying not to take children to crowded places, especially places with poor air circulation, during the high incidence season of respiratory diseases; Pay attention to open the window regularly for ventilation indoors, and isolate it from the sick family if possible; Pay attention to hand hygiene and remind children not to touch their eyes, nose and mouth with unclean hands.

13. Will children have sequelae after the flu?

Most children will not leave sequelae after being infected with the flu. However, after the flu temperature is normal, cough and runny nose may last for a week or even longer. The treatment is mainly symptomatic, keeping the air moist and promoting airway recovery. If cough seriously affects rest, you can take some antitussive drugs under the guidance of a doctor. Some children may have chronic cough due to airway hyperresponsiveness, especially those with eczema and wheezing history, and can be given medication under the guidance of a doctor.

14. How to prevent the spread of influenza in schools and families?

Schools should organize and mobilize students and faculty to get flu vaccine before the flu season begins; It is necessary to strengthen health education for students and their families, help and urge students to develop good hygiene habits, such as washing hands frequently and maintaining environmental hygiene; The classroom should be ventilated regularly; The school monitors students’ body temperature to find sick children in time; Once students are infected with influenza virus, they should rest at home and not go to school with illness; Attach importance to students’ physical exercise and enhance their physique and disease resistance.

Children suffering from influenza should ensure adequate rest, balanced nutrition, drink plenty of water and eat easily digestible food at home; Family members should maintain good hygienic living habits, pay attention to environmental hygiene and cough etiquette. If possible, we should try our best to isolate ourselves from sick family members; If you can’t isolate, you should wear a mask for protection. In addition, the indoor window should be ventilated regularly, but we should pay attention to keep warm in winter to avoid catching cold.

CCTV News:In Yangling, Shaanxi, the birthplace of Chinese farming civilization, there is such a scientific researcher: he has been rooted in the northwest for more than 30 years and stuck to the yellow land. He is not a farmer, but better than a farmer.

He carried out research on the occurrence law and comprehensive control of wheat stripe rust, revealed the pathogenic variation path and mechanism of wheat stripe rust, made clear the causes of the prone areas of wheat stripe rust in summer in China, improved the understanding of the epidemic system of wheat stripe rust, and provided theoretical basis for comprehensive control of wheat stripe rust in China. The comprehensive control technology system of stripe rust in the prone areas in summer in China was constructed, and remarkable results were achieved through demonstration and application promotion, which effectively controlled stripe rust in China. The infection route and pathogenic mechanism of wheat scab were revealed, and the key period of disease prevention and control was determined, which provided theoretical basis and technical support for the prevention and control of wheat scab.

"Wheat stripe rust and scab are major biological disasters that affect China’s food security and food safety. I came out of a wheat field, and my career is in a wheat field. " He is Kang Zhensheng, an academician of China Academy of Engineering, distinguished professor, a Changjiang scholar of the Ministry of Education, a doctoral supervisor, and the director of the State Key Laboratory of Crop Stress Biology in Arid Areas. In the research building of Northwest A&F University, CCTV reporter met Professor Kang Zhensheng and listened to him tell his own research story.

Germinate the long-cherished wish of "relying on science to help agriculture increase production and income"

Kang Zhensheng was born in Anyue, Sichuan in 1957. He was a famous "good student" from primary school to high school. In 1981, Kang Zhensheng became the first graduate student of the school after the reform of the enrollment system with excellent results and the first place in the graduation thesis grade. Kang Zhensheng, who was born in a farmer’s family, witnessed the huge losses caused by stripe rust to wheat production. His character of not being afraid of difficulties and being brave in exploration also made Kang Zhensheng sprout his long-cherished wish of relying on science to help agriculture increase production and income in the vast fields.

He began his research career under the guidance of Professor Li Zhenqi, a famous plant pathologist in China. Under the leadership of Li Zhenqi, Kang Zhensheng visited the key areas where wheat stripe rust occurred in Longnan, Longdong and Guanzhong of Shaanxi Province for many times.

Through intensive investigation and repeated demonstration, they first discovered a new pathogenic strain of stripe rust, which seriously harmed the main wheat varieties in China, from thousands of analysis materials and infected wheat plants through a large number of analysis experiments and field inoculation, and made an accurate prediction on the development trend and harm of this strain. The prevention and control strategies and solutions put forward were adopted by agricultural production departments, which played an important guiding role in preventing and reducing the harm of wheat stripe rust. This achievement won the third prize of scientific and technological progress in Shaanxi Province in 1987.

Become a conqueror of "wheat cancer"

Wheat stripe rust, known as "wheat cancer", is a low-temperature fungal disease spread through the air, and it is one of the main public enemies of wheat production in the world, which often reduces wheat production by 10% to 30%, and even leads to wheat failure in serious cases.

For many years, Kang Zhensheng led the team to focus on the interaction between pathogenic fungi and host wheat, and to find out what caused the frequent changes of wheat stripe rust from the aspects of histology, cytology, molecular cytology and molecular biology.

In order to find out the species of Berberis in the over-summer area of wheat stripe rust, Kang Zhensheng led his team members to travel all over the ravines of Gansu, Shaanxi, Sichuan and Yunnan provinces, and insisted on investigating the occurrence of wheat stripe rust. After a lot of field follow-up research, he sought the evidence that wheat stripe rust camped on Berberis in natural conditions and carried out experiments by using advanced scientific and technological means, and finally obtained a major discovery: sexual reproduction is the main pathogenic variation of wheat stripe rust in China. Wheat stripe rust is widely distributed in shrub leaves in northwest mountainous areas — — "Having children" on wild Berberis makes a new generation of germs become the "killer" of wheat varieties. On August 26, 2017, the research results were published in the top international academic journal Annual Review of Plant Pathology, which attracted wide attention at home and abroad.

Kang Zhensheng’s team established a technical system for forecasting wheat stripe rust in different places, and the accuracy of disease prediction was over 90%. The control technology system of "over-summer variable area" was established by taking measures such as crop structure adjustment, distribution of disease-resistant varieties, seed dressing with chemicals, winter spore isolation and Berberis treatment, which reduced the initial bacterial source of "over-summer variable area" by 40%, reduced the frequency of new races by 50% and extended the service life of disease-resistant varieties by 3-5 years, which played a key role in the effective control of stripe rust in China.

The research results benefit many countries and regions in the Belt and Road Initiative.

Wheat stripe rust is a serious biological disaster that affects the global wheat production safety for a long time. As the main academic leader of plant pathology in China, Kang Zhensheng led his team to make outstanding contributions to the research on the occurrence regularity, pathogenic mechanism and control technology of major diseases such as wheat stripe rust and scab. Kang Zhensheng promoted the establishment of "China Wheat Stripe Rust Germ Base Comprehensive Control Technology System", which was applied in 12 provinces, autonomous regions and municipalities in China, reducing the occurrence area of stripe rust by 50%, recovering more than 2 billion kilograms of grain losses every year, and increasing income and reducing expenditure by 4 billion yuan annually.

Since the "Belt and Road Initiative" was put forward, Kang Zhensheng’s team has successively cooperated with more than 10 countries and regions, including Kazakstan, Turkish and Ethiopian, collected and studied more than 1,300 standard samples of wheat stripe rust pathogens, and made China’s agricultural scientific research achievements with high quality and high yield of wheat "go abroad".

Today, Kang Zhensheng is still busy, but what he considers most now is to train young people, let them stand on their shoulders and grow up as soon as possible. "The work of revealing the genetic and molecular mechanism of virulence variation of Puccinia striiformis has just begun. In the future, while engaging in scientific research, we should train the young people behind us so that our agricultural science and technology can really run from the past to the leading stage."
