to analyze the clinical curative effect of electroacupuncture treatment on allergic rhinitis and its influence on immune function of patients. Methods: 75 patients with perennial allergic rhinitis in our hospital during January 2009 to April, 2013 were included in the study. They were divided into the conventional group (37 cases) and the electroacupuncture group (38 cases) according to the treatment scheme. All patients avoided the exposure to allergens. Patients of the conventional group received triamcinolone acetonide nasal spray method, once a day; the patients of the electroacupuncture group received the same as the control group of conventional therapy, at the same time accepted electroacupunctured on the acupuncture points at Yingxiang point, Tongbi point, Yintang point, Chuanzu point and Zusanli point. Both of the groups were treated continuously for 1 year. The study compared the changes in patients of nasal symptom scores, T lymphocyte subpopulation and immunoglobulin IgA, IgG, IgM before and after treatment. Results: 1) After the treatment, the clinical total effective rate of the control group was 72.97%; the clinical total effective rate of the curative group was 92.11%. The comparison of the two groups was with statistically differences (P< 0.05) with the electroacupuncture group superior to the control group. The clinical symptoms of the two groups relieved after treatment on the clinical symptom scores, which the downward trend in electroacupuncture group was more obviously. 2) Compared with before the treatment, CD4, CD4/CD8 and NK cells significantly increased, and CD8 cells significantly reduced in the patients of the two groups after treatment (P<0.01). Comparing the patients of the two groups after treatment, CD4, CD4/CD8 and NK cells of the patients of the electroacupuncture group were significantly higher than the control group, but CD8 cells was significantly lower than that of the control group (P<0. 01); 3) Compared with before the treatment, IgA, IgG, IgM expression levels of the patients of the two groups were significantly lower after treatment (P<0.05). Comparing patients of the two groups after treatment, the expression level of IgA, IgG, IgM in electroacupuncture group was lower than that in the control group (P<0.05). Conclusion: Electroacupuncture is effective in treating allergic rhinitis. It is relevant to the improvement of T cell subsets, NK cells and humoral immune level in the patients and the immunity-improving of organism.
