Abstract

SHI and COLLEAGUES, 1. Second Clinical Medical School, Nanjing University of CM, Nanjing 210023, Jiangsu Province, China; 2. Affiliated Hospital of Nanjing University of CM, Nanjing 210029, Jiangsu Province had the objective to study the primary and secondary factors of the allergic history, the frequency of acupoint application and the time of acupoint application in the treatment of bronchial asthma and optimize its scheme.

Background

Methodology

Eighty patients of bronchial asthma were selected as the subjects in the orthogonal trial. The herbal medicines were the empirical formula of acupoint application (prepared at the ratio as 2:2:1:1:1:1:1:1:1 of semen brassicae, rhizome corydalis, unprocessed radix kansui, asarum sieboldii, ephedra, semen lepidii, syzygium aromaticum, cortex cinnamomi and fructus gleditsiae) and used on bilateral Feishu (BL 13), Xinshu (BL 15), Geshu (BL 17) and Shenshu (BL 23). Firstly, two groups were divided according to allergic history (40 cases with allergic history and 40 cases without allergic history), and then four subgroups were divided on the basis of the two main groups, 10 cases in each one. Through studying three factors and two levels, i.e. allergic history (Factor A:AⅠ:with allergic history; AⅡ:without allergic history), the frequency of acupoint application (Factor B:BⅠ:4 times; BⅡ:10 times, in which, in the group of 4-time applications, the application was given once every 10 days; in the group of 10-time applications, the application was given once every 4 days); and the time of application (Factor C:CⅠ:4 h; CⅡ:8 h), the optimal scheme was screened on the basis of the attack frequency before and after treatment and the score of the asthma quality life questionnaire (AQLQ) before treatment and 6 months after treatment in the patients of each group.

Results

① The orthogonal trial indicated that the best optimal scheme was AⅠBⅡCⅠ, meaning the patients with allergic history were treated with acupoint application for 10 times, remained for 4 h. ②Factor B (frequency of acupoint application) and C (time of acpoint application) were the significant influential factors of AQLQ scores (both P<0.05). ③The comparison of the attack frequency and AQLQ score before and after treatment in all of the patients showed that the different combinations of factor levels induced the different impacts on the asthma attack frequency and AQLQ scores. Except in the group No.1 and the group No.5, the improvements were all significant in the rest groups, indicating the significant differences (P<0.05, P<0.01).

Conclusion

Acupoint application reduces apparently the attack frequency of asthma in the patients and improves the living quality. The primary and secondary relationship among the allergic history, the frequency of acupoint application and the time of acupoint application for the impacts on the therapeutic effects are:the frequency of acupoint application > the time of acupoint application > the allergic history. The best optimal scheme is AⅠBⅡCⅠ, meaning the patients with allergic history are treated with acupoint application for 10 times, remained for 4h.
