"Clear powder" trap! The software related to the viral spread of this service has great risks.

       CCTV News:Wechat has become the main contact method for many people. On many occasions, people have changed from leaving a phone number to adding friends. The WeChat address book is getting longer and longer, but some people in it rarely contact each other, so a service called "WeChat cleaning powder" came into being. I believe many people have received and seen this information, and even used this service. What you don’t know, however, is that this method may threaten your information security.

       Nianheng is a medical worker. One day in September this year, he suddenly received a WeChat message that surprised him.

       Nianheng: "After I opened it, I found that it was a teacher who had not contacted for a while. She sent a WeChat circle of friends, saying that she had recently used a WeChat powder cleaning service, which was very useful. There was a link at the bottom. I was also very surprised when I saw this news at that time, because I was under the impression that teachers generally did not send such news. "

one

       Nianheng sent a WeChat to the teacher to ask what happened. The other party replied that she saw a QR code of powder cleaning in a WeChat group. Considering the large number of friends in her WeChat, she really wanted to clean up her friends, so she tried.

one

       Nianheng: "At that time, after (the teacher) recognized the QR code, she sent some messages to the circle of friends without her knowing it, and also spread these messages to the group, which brought her a lot of trouble. I didn’t do anything else that afternoon, and I have been explaining that I was cheated. It was automatically sent after scanning the QR code. "

       During the interview, many WeChat users reported that they had received the WeChat clear powder link or QR code sent by their friends. These WeChat "clear powder" links will not only automatically send advertisements in the circle of friends, but also steal the user’s personal account information to sell for profit. Netizen Ms. Huang reflected on the consumer complaint platform "Gathering Complaints" that after using the "Clear Powder" service in May this year, she quickly discovered that there was a transaction on WeChat that she did not know, and the other party was an online game. Then she found that in this online game that she had never been exposed to, she actually had her own real-name registered account.

       Wechat "cleaning powder" is actually a big risk in controlling account security.

       So how does this so-called "cleaning powder" service operate, and what information security risks will it bring to users?

       Experts said that the principle of "cleaning powder" is to control the WeChat account to be cleaned by applying cluster control software, so that the account can automatically send messages to all its friends, and then the group control software can identify which ones are "zombie fans" and delete them according to "whether the information can be successfully sent and received". Whether it is mass messaging or group soliciting, users need to scan the QR code to authorize the provider of cleaning service to log in to the web version of WeChat. And behind this, there are huge risks.

one

       Hu Qimu, a senior researcher at the Digital Economy Think Tank: "The first one is that you authorized him, which is equivalent to him taking over your account, so that he can retrieve your personal information, including WeChat address book, chat record, and your mobile phone’s address book, chat materials, address book and some of your information, which may be leaked; Second, by taking possession of one of your accounts, he will register some other accounts to do something. If these things are illegal, it will have an impact on your personal credit information; Third, he may send some information such as fraud through your account. "

       The first case of "cleaning powder" in China was solved. Experts reminded that scanning code must be cautious.

       Recently, the Public Security Bureau of Nantong City, Jiangsu Province disclosed that they successfully detected a case of illegally obtaining computer information system data by using WeChat "cleaning powder" software in the "Clean Net 2020" special action, and all five suspects involved in the case were arrested, which is also the first case in China that illegally obtained information by using "cleaning powder" software.

       In the detection of the case, the police of the Netan detachment of Nantong Public Security Bureau in Jiangsu Province found that the illegally obtained user information around the "powder cleaning" software has formed a black industrial chain of illegal reselling.

       Cao Canhua, a policeman of Tongzhou District Public Security Bureau, Nantong City, Jiangsu Province: "After obtaining the control authority of WeChat account, the criminal suspect took the opportunity to illegally obtain the QR code information of users’ WeChat group chat, and saved these QR codes in the form of pictures on the server."

       Subsequently, the criminal suspect resold the user’s WeChat group chat QR code and other information to downstream criminal gangs such as fraud and gambling. In just three months, the criminal gang illegally obtained more than 20 million QR codes of users’ WeChat group chats, all of which were sold to fraud and gambling criminal gangs in Longyan, Fujian and other places. At the same time, it also paid attention to WeChat WeChat official account in batches, brushed reading and praised others, and made profits of more than 2 million yuan.

one

       Xu Hui, deputy head of the Netan Brigade of Tongzhou District Public Security Bureau, Nantong City, Jiangsu Province: "From illegally obtaining the relevant personal information of WeChat users to downstream advertising, marketing and other cyber crimes, the related network black ash production has formed an independent and closely coordinated industrial chain."

       At present, five suspects involved in the case have been arrested on suspicion of illegally obtaining computer information system data, and the case is being further processed. Lawyers said that "concealment, cross-regionality, and difficulty in fixing evidence materials" are the difficulties in rectifying such chaos, and these characteristics also increase the difficulty of users’ rights protection.

       Bo Meng, a lawyer of Beijing Jingshi Law Firm, said that based on the huge potential risks of "cleaning powder" software, it is not recommended to use such "services" to raise awareness of prevention and protect personal information; Don’t easily click on links and QR codes from unknown sources; When transferring money abroad, check it in advance.

       We also call on software developers to take more active supervision responsibilities and find ways to block such behaviors from the source to avoid users suffering losses.

Linqu: Optimizing the High-quality Planting Mode of Cherry and Building a Billion-level Industry of Fruit Industry

00:36
Qilu. com Lightning News May 16 th In recent years, Linqu County, based on the ecological advantages of mountains and rivers, takes big cherry as the "breakthrough" to increase income, and according to the "five ones" thinking and measures of defining a plan, formulating a standard, building a platform, casting a brand and forming a model, accelerates the development of fruit industry and makes every effort to build a fruit industry cluster with big cherry as the main part.
Zong Chuanbao is busy picking big cherries at Jinguo Family Farm in Yeyuan Street, Linqu County. He told reporters that cherries have been planted for 8 years. In recent years, through online and offline sales models, the annual income is very impressive.
With the rapid development of big cherry industry, there are many problems, such as the aging of fruit varieties, the small scale of business entities, and the extensive and backward planting habits. In view of this situation, Linqu County actively changed its thinking, "leading the industrial revitalization with excellent technology", started with promoting the upgrading of old orchards, popularizing new varieties of big cherries and standardized planting techniques, implemented the "park+standardization" promotion action, established a "base-market-terminal" big cherry circulation system, comprehensively optimized the planting and sales process, standardized production according to market demand, and ensured high-quality, safe and stable fruit supply.
In Henglilu Village, Chengguan Street, Linqu County, the village cooperative built a multi-arch cherry demonstration park, planted high-quality cherry varieties such as Meizao, Oba and Ramesses, and planted new varieties such as Luying series and Ruide in the open air to create a modern agricultural planting park with low energy consumption, low cost and high output.
Zeng Qingquan, secretary of the Party branch of Hengli Furnace Village, said that a demonstration shed of cherry in a 12-acre greenhouse was built in the village, which led the people to change the old traditional planting mode and introduce new varieties. Now the planting mode has been changed from tall and high-diameter to low crown and KGB, which is convenient for management and saves labor. The greenhouse uses a series of advanced means such as water and fertilizer integration, automatic unsealing and automatic heating to reduce labor intensity and improve economic benefits.
In recent years, Linqu County has planned to build eight rural revitalization and development areas, including facilities such as Big Cherry, Mountain Persimmon Farm Travel and Hongguo Town, build 30 agricultural characteristic industrial parks and 20 modern agricultural science and technology demonstration parks, cultivate 300 strong villages with "one village, one product" characteristic industries, lead industrial upgrading, promote agricultural efficiency and increase farmers’ income.
Wei Shujuan, director of the Agriculture and Rural Bureau of Linqu County, said that in order to continuously consolidate its advantages, the next step will be to build a 10 billion-level industrial cluster of fruit industry with big cherries as the main target, continue to do a good job in variety cultivation, quality improvement, brand cultivation and standardized production, improve seedling breeding, scientific and technological demonstration, large-scale planting, cold chain market, e-commerce and other elements of the whole industrial chain, strengthen brand cultivation, and enlarge and strengthen the leading regional public brand of big cherry. At the same time, relying on festivals, e-commerce and other platforms, we will open up the upward channel of agricultural products, fully promote the popularity of big cherry in the chest, and promote the high-end, intelligent and green development of the industry.

Great reward for animals’ confusing behavior

 

In nature, we often laugh because of the confusing behavior of some animals, and sometimes people are puzzled, such as-

Sloth: It will hang upside down in the tree after death.

It is hard to imagine how lazy a sloth is. Because it has been inactive for a long time, its body is covered with algae, and even its stool is only taken once a week.

Lazy sloths are so lazy that they don’t look around for food when they are hungry. They finally want to exercise, but sometimes they die because they misjudge their sports ability and physical strength.

Even if you meet the natural enemy horn carving, the sloth will not move, and the sloth caught in the sky by the horn carving will still maintain the posture of hanging upside down from the tree.

The sloth that has died will still hang upside down on the branch. When you glance at the sloth on the tree, sometimes you can’t tell whether it is alive or dead. 

Giant panda: the most casual animal in the animal world

Wild animals must always be vigilant at ordinary times, or they will be killed by natural enemies if they are not careful.

But how did the giant panda do it? Often the hips are wide open, the stomach is up, and the limbs are stretched out like a "big" word to sleep. Its abdomen is soft and collapsed, and there is no hard bone to protect its internal organs. If it is attacked, it will be basically fatal. Giant pandas are unprepared for their vital points and often sleep for a long time. Although it is said that "children who can sleep grow fast", giant pandas who can sleep like this are still on the verge of extinction. 

Misgurnus anguillicaudatus: You can’t breathe without farting.

The secret that loaches can live in water with bad environment lies in their unique breathing skills-in water with limited oxygen accumulated in silt, loaches don’t just rely on gills to breathe, they can directly go to the water surface and suck air into their mouths.

Misgurnus anguillicaudatus inhales through its mouth, transports the air to the intestine to absorb oxygen, and then discharges the air from its ass like giving up, so there are bubbles on the water surface.

Polar bear: When it is too hot, it will walk with its stomach against the ground.

As the largest carnivore on land, polar bears weigh nearly 800 kilograms and can reach 3 meters in length. Polar bears mainly hunt on the ice, so winter is the season when they can easily get food.

However, in summer, the ice surface decreases, polar bears can’t compete with seals in swimming speed, and their weight drops sharply because they often can’t eat. And its fur, which can resist the cold of MINUS 40 degrees, will have heatstroke reaction when the temperature is close to 0 degrees, so it is often seen that they crawl on the ground with their stomachs depressed, which is actually to cool their bodies.

Giraffe: the largest vomiting animal in the animal kingdom

"Rumination" means returning undigested food from the stomach to the mouth and chewing it carefully. Ruminants have four stomachs, and they have a very powerful ability to completely digest plants and absorb nutritional energy from them.

Giraffes are the largest ruminants, and the distance from the stomach to the mouth is more than 2 meters. When ruminating, they will see a spherical "vomit" on their necks moving in the direction of their heads. 

Shiba Inu: After the tail degenerates, the buttocks are exposed.

Shiba Inu was originally a very good hound, and the fox-like color can hide itself in bushes or hay; Excellent judgment allows them to hunt pheasants, rabbits and so on strategically. Shiba Inu has been very active since ancient times. Japanese Shiba Inu also has a close relationship with the family. Because of its loyal and brave personality, it is very suitable for being a watchdog.

Japanese Shiba Inu was also domesticated from wolves. During the long-term domestication, the muscles of the straight tail gradually degenerated, and the tail curled up and became a "curled tail", so the butt was exposed and clearly visible. 

Camel: The ultimate way for males to fight is to make faces.

As herbivores, camels also have canine teeth, which will also cause harm to their opponents when fighting too hard. For opponents who don’t care about their eyes at all, they will spit directly at each other-stomach contents, and the smell of this saliva will take a week to eliminate.

The two most powerful male camels will intimidate each other. They turned up the cheek pouches in their mouths and made faces to fight.

Besides, there are many animals that will do unexpected behaviors, some of which are to protect themselves, others are to attract the opposite sex …

I recommend this set of works by a well-known Japanese animal behavior expert, Shinya Hiroji-Animals that failed in evolution, which reveals some wonderful behaviors of more than 220 different animals in nature in the form of cartoons and words.

This set of books is very suitable for cultivating children’s reading interest, broadening their horizons and accumulating popular science knowledge. Every child who is curious about the world will love this set of books!

Xcar English improvement class 6 is not as careful as pickup truck

  [Original by Aika Car Vision Channel]

  Today, with the vigorous development of the automobile industry, the annual sales volume of one model is extremely amazing: according to the average annual sales volume of 2 million vehicles, one vehicle can be sold every 15 seconds on average; If it is lined up end to end, it can circle the earth 300 times, and this is only the number it sells in a year! This is "Pick-up/Truck".

  Today, there are several famous brands that constitute the "main force" of pickup truck models: F- series, Sliverado/Colorado (Sored/(|)), Ram series, Tacoma/Tundra (smooth road) and so on. What makes "Pick-up" popular all over the world and occupy a huge market share? Let’s walk into this issue of Xcar English Improvement Class.

Topic map

  Whether the product is good or not depends on the sales volume.

  According to the practice of previous upgrading classes, we will first introduce the development and history of the models. But in this issue, I will start with sales volume, explore the origin and development of pickup truck culture, and boldly predict that pickup truck models will eventually become "popular" in the new socialist modern countryside.

American car sales

American car sales

  Why do Americans love pickups so much? This will start from the 1920s. In the initial period of automobile manufacturing, vehicles were sold in the form of Separate chassis and body (chassis and body of non-loaded body structure are two parts). From the production of cars to the hands of consumers, a third party is responsible for the assembly of vehicle shells.

Pickup truck

  "Pick up" means "pick up" in English, which means it is convenient to load or unload goods. Therefore, the "bucket" vehicle is gradually called "Pick-up" (pickup truck is its transliteration). And "Truck" generally refers to large transport vehicles (but the basic name is personal habits).

  Since the 1950s, pickup trucks have gradually become an important production tool for American post-war economic recovery. Chevrolet El, Chevrolet Camino and Dodge Sweptine gradually entered people’s homes in the form of tool carts.

Pickup truck

  In 1963, the Protectionist Chicken Tax (referred to as "chicken tax") enacted by the United States to protect local automobile enterprises limited the dumping momentum of imported freight vehicles. Therefore, there has been a phenomenon that "every household buys a domestic pickup truck" in the United States, and the first car of many Americans is a pickup truck.

  Even so, pickup trucks have been criticized for a series of shortcomings, such as large displacement, "gas tiger", poor riding experience and no shape design. However, American pickup trucks played a role in the recovery of the national economy in World War II, and it was the "hero" for the United States to quickly become the world’s largest economy after the war.

A brief history of the development of glutinous rice balls: the stuffing was once called "round and not falling"

  Data Map: Wuhan time-honored traditional handmade dumplings are selling well. China News Agency issued ZhangChang photo

  Chinanews. com client March 2 (Reporter Shangguan Yun) Today is the Lantern Festival, people have started to buy according to their tastes, and merchants have launched various promotional activities according to the situation. Then, do you know why we eat glutinous rice balls on the Lantern Festival? What are the beautiful meanings in it?

  Lantern Festival, also known as "Shangyuan Festival" or "Lantern Festival", appeared in the Han Dynasty. In the Ming and Qing Dynasties, Lantern Festival, together with Spring Festival and Mid-Autumn Festival, was called the three traditional folk festivals in China, with a history of more than 2,000 years. The symbolic eating is "Tangyuan".

  According to public information, in the Tang and Five Dynasties, you had to eat "cocoon flour" and "round without falling into the corner" at the Lantern Festival, and in the Southern Song Dynasty, there was a "lactose dumpling". In the poem "Boiling a floating dumpling at the Lantern Festival", there was a sentence like "the stars are in the dark clouds, and the beads are floating in turbid water". These foods can be regarded as the predecessors of glutinous rice balls. By the Ming Dynasty, there were more names for "Yuanxiao".

  Data map: Beijing time-honored brands are now shaking Yuanxiao, which is in short supply.

  Dumplings are made in different ways from Yuanxiao, which is "shaken" and wrapped. The fillings can be vegetarian, sweet and salty, and there are many patterns. The sweet fillings generally include bean paste, jujube paste, nuts, etc., and the salty fillings generally include diced fresh meat and shrimp.

  In addition, there are dumplings filled with vegetables, which are composed of mustard, onion, garlic, leek and ginger. They are called "Five-flavor Yuanxiao", which means hard work, long-term progress. In recent years, there have been various "trendy" flavors of glutinous rice balls, such as strawberries, mangoes, durians, flowers, chocolates, etc., and some merchants have even introduced frozen fruit Yuanxiao that does not need to be cooked in the pot.

  Recalling the Lantern Festival when I was a child, Zhong Qin, who lives in Nanjing, said that there are different names for Lantern Festival and glutinous rice balls in Nanjing, and the boundaries are not so obvious. When I was a child, I always ate glutinous rice balls.

  Data map: there are also skills in rubbing dumplings, otherwise they will bloom as soon as they are cooked. Photo by ZhangChang

  "Whenever we approach the Lantern Festival, we begin to prepare noodles and fillings. Take boiled water and noodles first, and add water a little. " Zhong Qin said that every time the family made dumplings, they were very happy. "There are many kinds of fillings. The traditional flavors are sesame, bean paste, pure meat and vegetable meat. Later, white sugar with suet and peanuts with brown sugar were used, which was delicious."

  How to eat dumplings? Many people may say "cooking", but in fact, there are many methods such as steaming, frying and frying, which are equally delicious. Zhong Qin said that when frying, the oil should drown the dumplings. Put the wrapped raw dumplings directly into the boiling oil pan, turn them gently, and then fish them out when they turn golden yellow. "Sometimes the fried dumplings will swell up and taste crispy and delicious.".

  "The shape of glutinous rice balls is similar to that of a full moon, symbolizing reunion and good luck. Therefore, eating glutinous rice balls represents the wish of family reunion and harmony." Gao Wei, a folk expert, explained that no matter whether it’s called Tangyuan or Yuanxiao, no matter what kind of production method, people’s good wishes for their future life are pinned.

How to cough in autumn?

  Wu yanbing

  In autumn, the climate is dry and the temperature is low, so all kinds of discomfort symptoms of respiratory tract always love to make trouble in this season. Many people have this feeling. In autumn, their throats are like they can’t be pulled open. They are hot, dry and itchy, and have a lot of phlegm. If they are not careful, they will be harassed by coughing, which will be annoying. Today, let’s talk about why the respiratory tract is fragile in autumn and who is prone to cough.

Cough is not necessarily a bad thing.

  The respiratory tract is divided into upper respiratory tract and lower respiratory tract. The upper respiratory tract includes mouth, nose, pharyngeal cavity and throat, and the lower respiratory tract consists of trachea, bronchus and lung. Respiratory tract is the internal organ that people have the most contact with the outside world every day, and it is vulnerable to various external stimuli, such as cold, heat, dryness and infection. However, the lung is a relatively "cute" organ. It does not feel hot or cold, pain or touch. Frankly speaking, it has no feeling, and the biggest response to injury is coughing.

  When the airway is stimulated, the nerve reflex will make the human body produce a series of actions: the glottis are closed, and the breathing muscles contract rapidly to produce exhalation; Because the glottis is closed, the breath can’t go out, and the pressure in the chest cavity rises sharply, which in turn pushes the glottis open; Then, the gas is ejected at high speed, taking out the "bad" things in the trachea — — This is the protective defense mechanism of the lung.

  Therefore, coughing is not necessarily "sick", and coughing when sick is not necessarily a bad thing. Cough can help people expel germs from the body, which is conducive to the improvement of their condition.

  Of course, coughing is very annoying. Cough during the day; Cough at night; Talk too much and cough; Cough when inhaling cold air; Especially when coughing violently in public, not only the patient feels uncomfortable, but also others feel nervous. When some people cough violently, they will retch, affect their sleep, and even have pneumothorax. If the pleura on the lung surface ruptures, they will also have chest pain and hold their breath, which will be life-threatening in severe cases. Some patients with severe cough can lead to loss of consciousness, which is called "cough syncope" in medicine. This situation is very dangerous when driving or working at high altitude. Therefore, patients with relevant medical history should go to the hospital as soon as possible for symptomatic treatment.

  According to the duration, there are three situations.

  When it comes to coughing, we must first distinguish whether it is a real cough. Some people call the action similar to "clearing throat" cough, usually one or two times, because they feel uncomfortable in the throat or something sticks; Some coughs are habitual actions, which are common in smokers and are mostly caused by pharyngitis. What is really a cough is mostly manifested as a series of coughs one after another.

  In medicine, cough is divided into acute cough, subacute cough and chronic cough according to the length of cough time.

  1. Acute cough refers to cough within 3 weeks, mostly cough after infection, which is caused by diseases such as colds and tracheitis;

  2. Subacute cough refers to cough from 3 weeks to 8 weeks. In addition, this situation occurs in older patients, mainly due to post-infection cough;

  3. Chronic cough refers to cough with a course of more than 8 weeks. The main causes are cough variant asthma, postnasal drip syndrome (upper airway cough syndrome), eosinophilic bronchitis, gastroesophageal reflux cough and allergic cough.

  Seasonal cough is mostly caused by these conditions.

  Cough can appear all the year round, but it happens frequently when the season changes. Because the alternation of cold and hot is obvious when changing seasons, especially in autumn, many people do not pay attention to adding clothes and keeping warm in time, and their immunity is reduced, which will create opportunities for all kinds of bacteria and viruses to invade the human body, and then respiratory tract bacterial or viral infection will occur, and the incidence of cough after infection is higher, and respiratory tract infection is easy to induce cough variant asthma. This is also the main reason why everyone feels that it is easy to cough in autumn.

  Why do you cough after respiratory tract infection? In fact, post-infection cough is a respiratory symptom caused by airway inflammation repair. After the infection improves, it will be cured by simply using antitussive drugs, and the course of disease is relatively short.

  The essence of cough variant asthma is the increase of airway sensitivity caused by chronic airway inflammation, which is non-infectious and can be induced by respiratory infection without taking anti-inflammatory drugs. It may or may not be allergic. Although it is called "asthma", the patient has no breathing and his lung function is normal. However, some patients can turn into typical asthma. Therefore, correct treatment can reduce the incidence of typical asthma.

  The dry and cold climate is very unfriendly to the airway, and the cold itself is a kind of stimulation, while the low temperature reduces the water content in the air, which makes the airway more sensitive when it is short of water, thus leading to cough and wheezing. Nasal cavity can warm and humidify inhaled air, but too dry, breathing with open mouth and strenuous exercise may reduce airway humidity and increase airway sensitivity.

  In addition, there are allergic factors. In addition to spring, pollen allergy in autumn is also very serious, and both spring and autumn are the seasons prone to allergic cough, allergic rhinitis and asthma.

  It should be reminded that cough variant asthma, postnasal drip syndrome, eosinophilic bronchitis and allergic cough are all related to allergies to some extent. If there are symptoms such as sneezing, runny nose, itchy eyes and nose, and watery eyes while coughing, it will be very effective to receive antiallergic treatment if you go to the hospital to find out that eosinophils are high and total IgE (immunoglobulin E) is high.

  Why do diagnostic tests often choose CT?

  Theoretically, lung CT is not a necessary examination to see cough. In most cases, the lung CT findings of patients with simple cough are normal. Most chronic coughs, such as cough variant asthma, eosinophilic tracheitis, allergic cough, etc., have no obvious lesions in the lungs. Then why do doctors often recommend lung CT examination when they go to the hospital to see a cough?

  Because doctors must first rule out some serious diseases, such as tuberculosis, lung cancer, bronchiectasis and so on. The treatment of these diseases is mainly to treat the primary disease, not to treat cough alone. Doctors should first see if there is any disease in the lungs, and the best way to "see" the lungs is lung CT and X-ray chest film.

  Which is clearer, lung CT or X-ray chest film? Lung CT is relatively clear, X-ray chest film will produce many artifacts, and heart blood vessels and bones may also block the focus, so bronchiectasis and lung cancer are mostly diagnosed by lung CT, while infectious diseases such as tuberculosis and pneumonia can be diagnosed according to X-ray chest film.

  The attending doctor usually asks the patient’s medical history in detail, initially judges the nature of cough and considers what examination to do. For the elderly, patients with chronic cough and hemoptysis, lung CT examination is the first choice. Because the X-ray absorbed dose of lung CT examination is higher than that of chest X-ray film, it is suggested that patients should take the recent imaging results with them when they go to different hospitals one after another to avoid repeated examination.

  Do I have to take medicine for coughing?

  Many old people give medicine to their children when they cough, saying, "I want to suppress the disease"; Some patients are afraid of tracheitis, and then turn into chronic cough, and take medicine as soon as cough appears. But as long as it is medicine, there are side effects, especially for children. Therefore, if you don’t have a severe cough, don’t take cough medicine in a hurry, but see a doctor in time to take medicine for the cause.

  For patients with cough, the doctor’s primary concern is whether there is respiratory infection. If there is a severe cough, the stimulation of the airway may aggravate the inflammatory reaction and delay the improvement of the condition. This situation requires symptomatic medication. Let’s talk about what drugs may be used for cough.

  ● antitussive drugs

  Antitussive drugs work quickly, but they don’t target the cause. Commonly used antitussive drugs mainly include compound methoxyphenamine, licorice tablets, dextromethorphan, compound codeine syrup, traditional Chinese medicine pulmonary cough, loquat syrup, etc., which can achieve antitussive purpose by inhibiting central and peripheral cough reflex, antiallergic, bronchiectasis and other mechanisms. Among them, compound methoxyphenamine is mostly used to treat acute and chronic cough, and compound dextromethorphan solution is often used to treat cough after a cold.

  Most western medicine antitussive drugs are compound preparations, which may include antitussive, chlorpheniramine, pseudoephedrine, etc., with relatively more side effects, but little impact, so you can take them with confidence. Taking chlorpheniramine will cause drowsiness, which is not suitable for professionals who need to concentrate on their work, such as drivers. You can change other antitussive drugs according to your doctor’s advice.

  It should be noted that most western medicine compound antitussive drugs have the same ingredients or substitute ingredients, so do not take them at the same time.

  ● Antiallergic drugs

  Commonly used antiallergic drugs include loratadine and cetirizine, which are suitable for cough caused by allergic factors, especially for patients with allergic rhinitis.

  Among them, montelukast is a relatively safe drug for treating asthma and allergic rhinitis, and can be used simultaneously with other antiallergic drugs.

  In addition, among inhaled hormones and bronchodilators, salmeterol and fluticasone, budesonide and formoterol are commonly used to treat cough variant asthma, eosinophilic tracheitis, allergic cough, etc., which can reduce the probability of patients developing typical asthma while relieving cough.

  Many patients are worried about the side effects when they hear hormones. In fact, these drugs have been on the market for a long time, and the incidence of serious side effects observed is very low, which is relatively safe. It is important to gargle in time after inhalation to remove the excess drugs in the mouth.

  Low acid inhibitor

  Include omeprazole and lansoprazole, which can inhibit gastric acid secretion, and is mainly used for gastroesophageal reflux cough.

  ● Antibiotics

  Including cephalosporins, azithromycin, etc., mainly used for cough caused by infection.

  Low expectorant drugs

  Including eucalyptus, acetylcysteine capsules, ambroxol hydrochloride, fresh bamboo juice, etc., which can dilute sputum, and sputum is not easy to cough up and is suitable for postnasal drip syndrome. However, routine use is not recommended for dry cough.

  How to distinguish "COVID-19" cough from common cough?

  Now China is making every effort to prevent and control the COVID-19 epidemic. When it comes to "cough", it will inevitably make people nervous. So, what’s the difference between a cough caused by Covid-19 and a cough caused by a common respiratory infection?

  In view of the complexity of symptoms caused by Covid-19, it is impossible for patients to screen for infection by themselves. Clinically, in addition to fever, Covid-19 infection can sometimes be characterized by simple cough (mostly without sputum), which can also be the only first symptom of COVID-19 patients.

  Therefore, if you have a cough, you should pay attention to the symptoms of cough and go to a regular hospital in time if you have a history of epidemiological contact. At this time, don’t buy or take medicine by yourself, so as not to delay the diagnosis of the disease and cause the spread of the virus.
