Objective: The purpose of this study was to evaluate the clinical efficacy of Juqin mixture aerosol inhalation in bronchiectasis patinets. Method: One hundred bronchiectasis patinets with phlegm-heat obstructing lungs were randomly divided into treatment group and control group

with 50 cases each. Both groups were treated with conventional western medication including sputum drainage and short-term use of antibiotics

while Juqin mixture aerosol inhalation was added in the treatment group. The treatment course lasted 15 days. The scores of traditional Chinese medicine syndromes

the therapeutic effect and pulmonary function were observed before and after treatment. Result: After treatment

the syndromes scores including cough wheeze

thick yellow phlegm

hemoptysis or bloody sputum

feel of hot or thirsty

chest epigastric fullness

red tongue with yellowish or greasy fur

were all improved to different degrees in both groups. The scores of symptoms such as cough wheeze

thick yellow phlegm

chest epigastric fullness

red tongue with yellowish or greasy fur in the treatment group were significantly lower than those in the control group (P<0.05

P<0.01). The clinical effective rates were 90.00% in the treatment group

higher than in the control group 73.47% (P<0.05). After treatment

the pulmonary function [forced vital capacity(FVC%) predicted values

forced expiratory volume in one second predicted values(FEVl%) and FEVl/FVC] improvement in the treatment group was better than in the control group. Conclusion: Juqin mixture aerosol inhalation combined with conventional therapy could significantly improve the clinical efficacy in bronchiectasis.
