Objective: To observe the clinical efficacy of Buzhong Yiqi decotion combined with Seretide (Fluticasone propionate/Salmeterol) in treatment of patients with bronchial asthma (BA) at remission. Method: 60 patients with BA at remission were randomly divided into observation group and control group

30 cases in each group. The patients in the control group were treated with Seretide (Fluticasone propionate 50 μg/Salmeterol 250 μg) on the basis of anti-inflammatory

oxygen

cough

asthma and other conventional treatment for 12 weeks. The patients in the observation group were treated with Buzhong Yiqi decotion on the basis of the control group. The course was 2 weeks

3 courses were carried on

and the treatment interval was one week. The clinical efficacy was evaluated and the lung function index such as (forced vital capacity

FVC)

(forced expiratory volume in the first second

FEV1)

FEV1/FVC% were compared after the treatment. Result: After treatment

the clinical total effective rate of the observation group was 86.67%

which was significantly better than that of the control group (66.67%) (P<0.05);After treatment

the lung function index of the patients in the two groups improved

and the lung function index such as FVC

FEV1

FEV1/FVC of the observation group improved more significantly than the control group and before treatment (P<0.05). Conclusion: Buzhong Yiqi decotion combined with Seretide is effective in improving lung function in patients with BA at remission.
