慢性支气管炎(简称慢支)是危害人民健康的常见病、多发病。近年来,有人用死卡介苗(简称死卡)和胸腺肽治疗均取得满意疗效,但死卡注射局部反应较重,易被感染。胸腺肽价格昂贵,不易被群众接受。 Chronic bronchitis (referred to as chronic bronchitis) is a common disease endangering people’s health, frequently-occurring disease. In recent years, some people with dead BCG (referred to as dead card) and thymosin treatment have achieved satisfactory results, but the local injection of dead card heavier, easily infected. Thymosin is expensive and not easily accepted by the public.
