Clinical observation of Zhen'ai needling method in Nei Jing (Classic of Internal Medicine) on improving quality of life in patients with allergic rhinitis

Objective:To observe the effect of Zhen'ai needling method in Nei Jing (Classic of Internal Medicine) on quality of life in patients with allergic rhinitis (AR).Methods:A total of 99 patients with AR who met the inclusion criteria were randomized into a conventional needling group (51 cases) and a Zhen'ai needling group (48 cases).The conventional needling group was treated with acupuncture at Zusanli (ST 36),Hegu (LI 4),Juliao (ST 3),Yingxiang (LI 20),Yintang (GV 29),Shangxing (GV 23) and Baihui (GV 20).The Zhen'ai needling group added acupoints of Zhen'ai needling method {Lieque (LU 7),Shanglianquan [Extra,located at 1 cun above Lianquan (CV 23)] and Tianrong (SI 17)} in addition to points in the conventional needling group.The needles were retained for 30 min.The treatment was performed twice a week.All patients were assessed by total nasal symptom score (TNSS),total ocular symptom score (TOSS) and sino-nasal outcome test-20 (SNOT-20) before and after 15 treatments to evaluate the quality of life.The clinical efficacy was evaluated after 15 treatments.Results:During the treatment,8 cases dropped out in the conventional needling group and 7 cases in the Zhen'ai needling group.There were no significant differences in TNSS,TOSS and SNOT-20 scores between the two groups before treatment (all P＞0.05).After treatment,the total effective rate of the Zhen'ai needling group was 92.7％,versus 88.4％ in the conventional needling group.There was no significant difference between the two groups (P＞0.05).After treatment,there were no significant differences between the two groups in TNSS and TOSS scores (both P＞0.05).The SNOT-20 score of the Zhen'ai needling group was lower than that of the conventional needling group,and the difference was statistically significant (P＜0.05).There were statistical differences between the two groups in the scores of cough and nasal reflux (to the throat) of the NOT-20 scale (both P＜0.05).Conclusion:Both Zhen'ai needling method and conventional acupuncture are effective in the treatment of AR.Zhen'ai needling method has a better effect than conventional acupuncture in improving cough and nasal reflux (to the throat) in AR patients.
