ABSTRACT

[Objective] To observe the influence of Modified Qianjin Weijing Decoction (MQWD) on airway clearance in patients with acutely exacerbated chronic obstructive pulmonary disease (AECOPD) , which was differentiated as the syndrome of phlegm-heat congesting lung. [Methods] A prospective control trial was carried out in 60 AECOPD patients with phlegm-heat congesting lung. The patients were equally randomized into two groups: the treatment group (group A) was treated with MQWD and routine western medicine, and the control group (group B) with routine western medicine only. The therapeutic effect, indexes of lung function including FEV1 (forced expiratory volume in one second), FVC (forced vital capacity), FEV1/FVC, Zrs (total respiratory impedance) and R5 (total airway resistance), and in particular, the airway clearance rate (Ct) were observed and compared in the two groups. [Results] In the treatment group, the markedly effective rate was 70.00 % , higher than that (23.33 % ) in the control group ( P 0.05) but Ct in 60-minute and 90-minute treatment was much improved in the treatment group than that in the control group (P
