近年来治疗哮喘和慢性阻塞性肺疾病(COPD)的新药日益增多,其数量超过了过去的几十年。而哮喘的发病率和死亡率却仍在上升。COPD的气流阻塞仅部分可逆,病残率无显著下降。近几年许多研究已倾向于哮喘的病因和发病机理方面,工作的重点是特异反应的遗传学基础。在引发哮喘这种特殊 The number of new drugs used to treat asthma and chronic obstructive pulmonary disease (COPD) has been increasing in recent years, more than in the past few decades. The incidence and mortality of asthma are still on the rise. COPD airflow obstruction only partially reversible, no significant decline in morbidity. In recent years, many studies have tended to focus on the etiology and pathogenesis of asthma. The focus of work is on the genetic basis of specific responses. This asthma is causing this special
