Chronic airway obstruction is also a characteristic change of COPD in which transforming growth factor - β _1 ( TGF - β _1 ) has important role. 同时,在COPD中慢性气道阻塞(CAO)是重要的特征性病变。在慢性气道阻塞(CAO)的发生中,纤维源性生长因子如转化生长因子-β1(TGF-β1)的作用正引起关注。
Asthma is chronic airway inflammation, characterized by poorly reversible airway obstruction and hyperactivity. 哮喘是一种慢性气道反应性炎症,其主要临床特征为气道高反应性和可逆性的气道阻塞。
Asthma is a chronic disease of the airway which is clinically characterized by airway obstruction, enhanced bronchial responsiveness to spasmogens ( airway hyperactivity ), and it has not one more effect therapy. 支气管哮喘(BronchialAsthma)简称哮喘,是以气道高反应性为特征的慢性气流阻塞性疾病,目前并无一种治疗方法能够彻底治愈哮喘。
Bronchial asthma is traditionally defined as a chronic disease with allergic disorder and persistent inflammation which results in generalized airway hyperresponsiveness and reversible obstruction of airflow. 支气管哮喘是一种气道慢性过敏反应炎症性疾病,长期慢性炎症导致气道反应性增高和可逆性气流阻塞。
