Abstract：Objective：To observe the clinical effect of Bailing capsules combined with inhalation of pulmicort respules on senile cough variant asthma. Methods：A total of 108 elderly patients with cough variant asthma were selected and divided into the control group and the observation group according to the random number table method，with 54 cases in each group. The control group was treated with aerosol inhalation of pulmicort respules， and the observation group was additionally treated with Bailing capsules based on the treatment of the control group. Both groups were treated for three courses，four weeks being a course. After treatment，the clinical effects，lung function indexes and levels of inflammatory factors in the two groups were observed and compared. Results： After treatment， the total clinical effective rate was 90.74% in the observation group， higher than that of 79.53% in the control group， the difference being significant(P＜0.05). Before treatment，there was no significant difference being found in the comparison of levels of peak expiratory flows(PEF)，forced expiratory volume in one second(FEV1) and the ratio of forced expiratory volume in one second to forced vital capacity(FEV1/ FVC) between the two groups(P＞0.05)；after treatment，the above levels in both groups were significantly increased when compared with those before treatment(P＜0.05)，and the above indexes in the observation group were higher than those in the control group(P＜0.05). Before treatment， there was no significant difference being found in the comparison of ratio of interleukin- 4 to interferon- γ(IL- 4/IFN- γ) and level of interleukin- 17(IL- 17) between the two groups(P＞0.05)； after treatment， the above two indexes in the two groups were significantly decreased when compared with those before treatment(P＜0.05)，and the above two indexes in the observation group were lower than those in the control group(P＜0.05). Before treatment， there was no significant difference being found in the comparison of levels of serum T helper 17(Th17) cells，regulatory T(Treg) cells and Th17/Treg between the two groups(P＞0.05)；after treatment，the levels of Th17 and Th17/ Treg in the two groups were significantly decreased when compared with those before treatment(P＜0.05)，and the levels of Treg were significantly increased(P＜0.05)，and the improvement of the above indexes in the observation group was more significant than that in the control group(P＜0.05). Conclusion：The therapy of Bailing capsules combined with inhalation of pulmicort respules for senile cough variant asthma has a significant curative effect， which can effectively reduce the inflammatory responses of the bodyand improve the lung function of patients.
