支气管哮喘(哮喘)是一种以气道高反应性和慢性气道炎症为特征的变态反应性疾病。病因较为复杂,其患病率和病死率在很多国家尤其是发展中国家都呈上升趋势,是当今世界上最常见的慢性气道炎症性疾病。近年来随着分子生物学的飞速发展,国内外学者采用各种不同的遗传学研究方法对哮 Bronchial asthma (asthma) is an allergic disease characterized by airway hyperresponsiveness and chronic airway inflammation. The cause of the disease is more complex, and its prevalence and mortality are on the rise in many countries, especially in developing countries. It is the most common chronic airway inflammatory disease in the world today. In recent years, with the rapid development of molecular biology, domestic and foreign scholars use a variety of genetic research methods on the asthma
