Objective： To observe the clinical effect of Bailing capsules combined with respiration rehabilitation training for patients with chronic obstructive pulmonary disease at stable stage.Methods：Divided 117 cases of patients with chronic obstructive pulmonary disease at stable stage into the observation group being 59 cases and the control group being 58 casesrandomly.The control group was given the routine medicine for treatment，while the observation group was additionally given Bailing capsules combined with respiration rehabilitation training，and the treatment for both groups lasted for 1 year.Observed the changes of the frequency of acute attack，the forced expiratory volume in one second(FEV1)，FEV1/forced vital capacity(FVC)，quality of life scores(including symptoms、activities the influence scores of social activities and psychology on COPD)，Hamilton anxiety scale(HAMA)scores and Hamilton depression scale(HAMD)scores of patients in both groups before and after treatment，and evaluated the clinical effect of both groups.Results：The total effective rate was 77.97%in the observation group and was 55.17%in the control group，the difference being significant(P＜0.05).After treatment，the frequency of attack within 1 year in the observation group was fewer than that in the control group，difference being significant(P＜0.05).FEV1and FEV1/FVC in the observation group were higher than those in the control group，differences all being significant(P＜0.05).Quality of life scores，HAMA scores and HAMD scores in the observation group were lower than those in the control group，differences all being significant(P＜0.05).Conclusion：The application of Bailing capsules combined with respiration rehabilitation training for patients with chronic obstructive pulmonary disease at stable stage has significant clinical effect，which can reduce the frequency of acute attack，improve pulmonary function，promote quality of life，and relieve the anxiety and depression of patients.
