Editor The World Health Organization has listed allergic diseases as one of the 21st centuries of key research and prevention of diseases.At present, in the spring, the allergies of pollen entered a high incidence.This edition has launched special planning today to focus on the prevention and treatment of allergic diseases.

Spring is mellow and the flowers are intoxicated. It is a good time to travel.However, for many friends, this is a difficult season for itchy, nose, and constant sneezing.In the past two days, Mr. Wang from Beijing exposed various types of anti -allergic drugs in the circle of friends and essay- “officially lists spring as my most annoying season.”

“Spring is the season of high allergies. The main reason is that the spring flowers bloom. As the temperature gradually increases, a large amount of allergic trees and wood pollets are scattered in the air, causing pollen allergies.” Beijing Century Altar Hospital Affiliated to Capital Medical UniversityWang Xueyan, director of the Perverted Reaction Center.

Ms. Li in Xi’an, Shaanxi told reporters that she felt more and more allergic people around.”Many colleagues who are not allergic to pollen have also experienced runny nose and tears this year. Everyone feels strange. Not only is pollen allergies, all kinds of allergies around them seem to be becoming more and more common.”

Ms. Li’s feelings are not a case.In recent years, allergies have indeed become larger and larger.According to statistics, the number of pollen allergies in my country has reached 200 million.At present, the prevalence of allergic diseases has risen, becoming the sixth largest chronic disease in the world.

Allergies are excessive reactions produced by the body

Ms. Wang from Yinchuan, Ningxia has been “fighting” with allergies for many years.She is allergic to pollen in the spring and autumn seasons and is usually allergic to mango.These allergic symptoms include rash, itchy throat, itchy eyes, and runny nose.”Itching is more difficult than pain. When the symptoms are severe, it affects daily life very much.” Ms. Wang said that last year, she started to raise rash.After going to the hospital for examination, I found that it was allergic to tomato.

Yin Jia, a professor of abnormal response department of Beijing Union Hospital, introduced that allergies are an excessive reaction of physical generation to foreign substances, and it is a disorder in the immune system.When the allergies occur, the immune system regards some of the commonly acceptable and tolerant substances as foreign objects, which resists and removes it.

Wang Xueyan further explained to reporters as an example of the allergy of pollen as an example: “Generally allergic to pollen, indicating that the patient’s body’s immune system mistakenly identifies the original harmless pollen as harmful substances. In order to clear these ‘harmful substances’, the body will produce a one.The series of abnormal immune responses, causing symptoms such as nasal itching, nasal congestion, sneezing, itching, tears, and rash. “

“After the pollen enters the patient’s body, it is more deposited in the upper respiratory tract mucosa, eye conjunctiva and other parts. Pollen allergens will stimulate local lymphocytes and lymph nodes, prompting it to produce specific immunoglobulin E. These specific immunoglobulin E will beIn -combination with hypertrophic cells and alkaline cells on the respiratory tract, conjunctiva, and allergens. When the patient is touched with pollen again, it will cause histamine release, capillary dilatation, tissue fluid exudation, and mucus secretion to increase, thereby appear.A series of clinical symptoms “” Wang Xueyan said.

Global allergic patients have continued to increase

Generally speaking, allergic diseases include food allergies, characteristic dermatitis, allergic rhinitis, and allergic asthma.”Among all kinds of allergic diseases, the prevalence of allergic rhinitis is the highest. According to data, since the 21st century, the prevalence of allergic rhinitis in my country has increased significantly, and the number of patients is estimated to be 250 million. From 2005 to 2011, from 2005 to 2011, from 2005 to 2011, from 2005 to 2011, from 2005 to 2011, from 2005 to 2011, from 2005 to 2011, In the past 6 years, the prevalence of self -reporting of allergic rhinitis in my country has increased from 11.1%to 17.6%, and the number of patients has increased by about 100 million. “Wang Xueyan said.

Feelive dermatitis is one of the allergic diseases and can affect multiple organs and systems throughout the body.According to the “Diagnostic and Treatment of Children’s Allergic Diseases”, the prevalence of dermatitis in children from 1 to 7 years old has increased rapidly, from 3.07 % in 2002 to 12.94 % in 2015.In addition, the prevalence of food allergies in the country is also rising.A paper from the China Centers for Disease Control and Prevention shows that from 2009 to 2018, China’s food allergies were 8%, which was higher than 5%from 1999 to 2008.Common allergen foods from high to low are shrimp, mango, shellfish, eggs, fish, beef, milk, and mutton. Sixty -percent patients with allergies are rash.

If the vision is expanded, it can be found that allergic diseases have become a major global epidemic.According to the statistics of the world abnormal reaction organization, the incidence of allergic diseases has increased by at least three times in the past 30 years.About 250 million people around the world have food allergies, 300 million people suffer from asthma, 400 million people suffer from allergic rhinitis, and one -tenth of the total population has a drug allergic response.

The environment and lifestyle change to the main cause

Why are there more and more people who are allergic now?Zhang Jianzhong, chief physician of the Department of Dermatology of the People’s Hospital of Peking University, believes that with the development of the industry, the human body has more opportunities to expose various bacteria, viruses and harmful chemical components.

The occurrence of allergic diseases is also closely related to changes in human lifestyles.Wang Xueyan told reporters that now people have lived indoors for a long time, and their outdoor activities have been short, which has led to obesity, dietary changes, and increasing indoor allergens.Studies have pointed out that long -term meditation in the room can also lead to a decrease in respiratory frequency and prolonged breathing cycle, which in turn increases respiratory resistance and increased airway reactivity.

In response to some patients who were not allergic to pollen before, but suddenly suddenly allergic, Wang Xueyan explained: “This is mainly the result of the interaction of genetic factors and environmental factors.For a while, there are individual differences in the length of this time.

Wang Xueyan told reporters that with the increase in global climate warming and the increase in carbon dioxide concentration, some sensitized pollen output increased and the loose powder period was extended, which led to high exposure of sensitized pollen in susceptible people.In addition, suddenly the allergy of pollen is also related to the immune state of the human body. For example, excessive fatigue and poor mood can cause immune dysfunction of the body, inducing or aggravated allergic reactions.

In Yin Jia’s opinion, the exquisite lifestyle and frequent use of washing supplies will destroy people’s natural skin protection barriers and natural gastrointestinal barriers.This is also one of the reasons for skin allergies and food allergies.The human skin barrier, respiratory barrier, and digestive tract barriers are microcreal composed of various microorganisms.The intestine has a micro -ecology of the intestine, and the skin has the skin of the skin. There are many beneficial bacteria that coexist with us to provide natural protection for the human body.Today, this balance is constantly being broken by some new lifestyles, such as repeated disinfection and excessive sun protection.Therefore, approaching nature and adjusting lifestyle is an important way to prevent allergic diseases.

Establishing immune tolerance is the key to prevention and control

More and more common allergic diseases are constitute a severe challenge to human health.The core strategy of preventing and controlling allergies is to establish immune tolerance.”Although most of the allergic diseases are not fatal, they still need to attach enough attention.” Ouyang Yuhui, chief physician of the perverted response (nasal allergies) of Beijing Tongren Hospital, said that some patients knew that they were allergic and did not check.Allergens; some people think that allergic rhinitis is sneezing, runny nose, and forbearance passes.Many people dragged to the later stage of complications. After the sinusitis, nasal polyps, and even asthma, it would be difficult to treat.For patients with allergic diseases, standardized diagnosis and treatment are very important.

Wang Xueyan suggested that after an allergic response, you first need to go to the perverted reaction department and related departments to check the allergens.After clarifying allergens, the doctor will provide the corresponding diagnosis and treatment plan according to the specific condition.Taking pollen allergies as an example, during the peak of pollen, the symptoms of patients are more obvious. The symptomatic treatment should be based on the symptomatic treatment of the drug, supplemented by immunomagnal treatment.The symptoms are based on specific immune therapy, which is mainly desensitization therapy.

Wang Xueyan particularly reminded that the best period of pollen allergies is the time of the pollen relief, and patients can perform desensitization treatment during this period.This is also the only treatment for the treatment of “going to root” that everyone often says.(Intern reporter Su Jingjing)
