Li Gang (pseudonym), a 0/8-year-old senior three student in Zhengzhou/KLOC, has been feeling breathless recently, and sometimes he has difficulty breathing, especially breathing, which makes him very scared. His parents quickly took him to the hospital for examination. The doctor told them that this is a symptom of asthma ● Asthma is closely related to allergic rhinitis, which is difficult to treat above and difficult to treat below; If the top and bottom are not good, treat the top first, because if the top is not good, the bottom is not good. This is an academic activity organized by Academician Zhong Nanshan, President of Chinese Medical Association. He expounded the relationship between allergic rhinitis (upper respiratory diseases) and asthma (lower respiratory diseases) from the aspects of pathogenesis and treatment. The World Health Organization has proposed in 2005 that allergic rhinitis and asthma are the same allergic diseases in the same airway, and they can induce each other. Research shows that 78% of asthma patients suffer from rhinitis, while the asthma prevalence rate of allergic rhinitis patients is close to 30%. If correct and effective treatment measures can be taken in the early stage of allergic rhinitis, many asthma can be effectively avoided. For patients with asthma, we should first control the symptoms of allergic rhinitis, because allergic rhinitis will aggravate the occurrence of asthma. And once the treatment of allergic rhinitis is neglected, asthma will recur soon. Although allergic rhinitis is very harmful, the treatment of the disease is often ignored by patients. Due to the public's lack of understanding of allergic rhinitis, it is easy to confuse the symptoms of allergic rhinitis with colds, delay the treatment opportunity and even delay the development of asthma. Zhang Wang, chief physician of the Department of Otolaryngology of the Provincial Military Region Hospital, said that compared with a cold, allergic rhinitis has the same four typical symptoms, namely stuffy nose, runny nose, itchy nose and sneezing. But the two are not difficult to distinguish, and patients can simply distinguish from the following aspects. Cold: usually accompanied by sore throat, cough, etc. In severe cases, there will be fever, headache, body aches, and even nausea and diarrhea. Allergic rhinitis: Typical symptoms are paroxysmal sneezing, runny nose, itchy nose, stuffy nose and itchy eyes. If you feel that your symptoms are suspected of allergic rhinitis, you can go to the otolaryngology department directly, and you can make a quick diagnosis through nasal endoscopy. Zhang Wang warned. ● Blocking sensitive nerves is effective. It is understood that advanced nasal endoscopic nerve block therapy is recognized as a more effective method to treat allergic rhinitis. Because allergic rhinitis, whether perennial or seasonal, has different pathogenesis, but it is related to the increase of parasympathetic nerve excitability. Li Xiumin, chief physician of the Department of Otolaryngology, Military Region Hospital, said that research shows that nasal parasympathetic nerve has at least two sources: pterygoid nerve and ethmoidal nerve. The latter is distributed in the high density area of serous glands of nasal mucosa and the nasal mound of sensitive parts of nasal cavity. According to the source and distribution characteristics of nasal parasympathetic nerves, doctors used nasal endoscope to accurately locate and block the nasal sensitive nerves to treat allergic rhinitis, and achieved satisfactory results. After treatment, most patients' symptoms of sneezing, runny nose and stuffy nose disappeared or alleviated. For chronic rhinitis, turbinate hypertrophy's disease, nasal polyps, sinusitis and pharyngolaryngitis, the minimally invasive treatment with nasal endoscope has a good effect. Under the guidance of nasal endoscope, the treatment will not cause accidental injury and ensure thoroughness. And patients with intractable nasopharyngeal diseases can consider using minimally invasive techniques for treatment. ■ Experts remind that like many diseases, allergic diseases are generally hereditary. For example, if one parent is allergic, then the child is more likely to suffer from allergic diseases. However, this does not mean that you will definitely get sick. As for external factors, indoor mites, molds and even pets may cause allergic rhinitis, and cockroaches and mosquitoes among insects are also one of the risk factors; Common outdoor allergy inducing factors are pollen and air pollution. Director Li Xiumin said that for allergic diseases with multiple factors, it is best to start with our practical tips. For example, we can't change our genes, but we can enhance our immunity through exercise; It can't change air pollution, but it can keep clean and reject cockroaches, molds and so on.
