Background Our previous study showed that Yifei moxibustion has good effect on chronic obstructive pulmonary disease (COPD) in stable stage, but the effect could be enhanced according to the suggestions of an expert questionnaire survey. It is of great significance to carry out clinical research on the relationship of moxibustion duration with clinical efficacy and suitability in COPD. Objective To study and optimize the appropriate duration of moxibustion treatment in COPD, and to evaluate its clinical efficacy and suitability. Methods One hundred and twenty patients with stable COPD were recruited from the First Affiliated Hospital of Henan University of Chinese Medicine from June to July 2017, and randomly divided into groups A and B with SAS software. Both groups received routine western medicine treatment and one course of Yifei moxibustion treatment (1.5 h each time for group A, and 2 h each time for group B, once every 15 days, for a total of six times in three months) . The primary outcome index was the number of colds during treatment, and the secondary outcome indices included clinical symptoms and signs scores, COPD Assessment Test (CAT) , pulmonary function, suitability evaluation〔using the Visual Analogue Scale (VAS) 〕, and the safety was evaluated. Results Except 29 dropouts, 91 cases (47 in group A and 44 in group B) were included in the Per Protocol Set and analyzed with full data set analysis. The results of repeated measures ANOVA showed that the main effects on the number of colds, score of chest tightness, CAT score and VAS score were significant between groups (P<0.05) . There were significant intergroup differences in the number of colds, the total score of clinical symptoms and signs, the score of each of the clinical symptoms and signs, the score of each of the clinical symptoms and signs, CAT score and VAS score at different time points (P<0.05) . No adverse events occurred in both groups. Conclusion Both types of Yifei moxibustion could reduce the number of colds, improve the cough, chest tightness and other clinical symptoms as well as the quality of life in stable COPD patients. But the efficacy of Yifei moxibustion lasting for 1.5 h each time was better, and was more applicable.
