Objective:To observe the therapeutic effect of acupuncture-moxibustion at different intervals on persistent allergic rhinitis. Methods: A total of 90 patients conforming to the inclusion criteria were randomized into three groups named A, B and C by randomized block method. Patients in all three groups received the same treatment of acupuncture and herbal cake-partitioned moxibustion at the same acupoints, while the treatment frequency was different. Patients in group A received the treatment once a week, group B twice a week and group C three times a week, and all the treatment lasted for 4 weeks. The total nasal symptom score (TNSS), total ocular symptom score (TOSS) and Sino-nasal outcome test-20 (SNOT-20) were evaluated before and after treatment. The self-rating score of symptoms was evaluated during treatment and 2 weeks after treatment. Results: The total effective rate was 80.0% in group A, 93.3% in group B, and 100.0% in group C. The total effective rate in group A was statistically different from that in group B and group C (both P＜0.05), but there was no significant inter-group difference in total effective rate between group B and group C (P＞0.05). After treatment, scores of TNSS, TOSS and SNOT-20 in all three groups dropped significantly, and statistically different from those before treatment (all P＜0.05); between-group comparison showed group B and group C decreased more obvious than group A (all P＜0.05). In self-rating score of symptoms, there were no inter-group statistically significant differences in the first 3-week treatment (all P＞0.05); after 4-week treatment, the score in group A was higher than that in group B and group C, and showed statistical significant (both P＜0.05); at 2 weeks after treatment, the score in group A was higher than that in group B and group C based on an everyday record, showing statistical significance (both P＜0.05). At the 11th day after treatment, the score in group B was higher than that in group C (P＜0.05). There were no significant differences between group B and group C at other time points (all P＞0.05). Conclusion: All three protocols are effective for allergic rhinitis. With the increase of treatment frequency, the therapeutic efficacy with a treatment frequency of twice a week and three times a week is superior to that of once a week. Frequency of three times a week has a better long-term effect than once and twice a week, together with the least fluctuation of symptoms.
