| To observe the effects of different acupuncture frequency on pulmonary function in patients with chronic obstructive pulmonary disease(COPD)and to compare the percentage of CD4+,CD3+,CD4+,CD8+and Th17 in different groups.Methods:Sixty cases in our hospital from February 2015 to February 2016 were included in the study and were randomly divided into high-frequency group and low-frequency group,with 30 cases in each group.Patients of both groups were treated at Pishu(BL 20),Weishu(BL 21),Feishu(BL 13),Shenshu(BL 23),Taiyuan(LU 9),Taibai(SP 3),Taixi(KI 3),Zusanli(ST 36).Additionally patients with external pathogen were treated with Hegu(LI 4),and patients with phlegm-turbidity obstructing middle-jiao were treated with Fenglong(ST 40).After needling sensation,high-frequency group was connected with electroacupuncture instrument,with the frequency of 100HZ,low-frequency group with 2HZ.Two groups were treated under the degree of tolerance,once a day,30 min/time,5 times/week,10 times as a course of treatment,2 courses of treatment in total.The Forced Expiratory Volume In 1 s(FEV1),forced vital capacity(FVC),FEV1/FVC ratio,maximum ventilatory volume(MVV),6 min walking distance(6-MWD),CD4+,CD8+and CD4+/CD8+and Th17 concentration changes were compared between the 2 groups after treatment.Results:1)The pulmonary function indexes including FEV1,FVC,FEV1/FVC ratio and MVV in low-frequency group were significantly better than that of high-frequency group(P<0.05)after treatment; 2)After treatment,6-MWD of low-frequency group was significantly improved(P<0.05).3)CD4+,CD4+/CD8+of both groups were increased,and CD8+,Th17 concentrations decreased.The low-frequency group was better than the high-frequency group,and the difference was statistically significant(P<0.05).Conclusion:Low-frequency acupuncture can improve lung function by improving the patient's immune function. |
