to observe the clinical effects of warm needling on rheumatoid arthritis.Methods:Patients with rheumatoid were treated with warming needling on the major acupoints of Guanyuan(CV 4),Qihai(CV 6),Zusanli(ST 36),Ganshu(BL 18),Shenshu(BL 23) and Pishu(BL 20),in combination with local acupoints and acupoints on the related meridians,meanwhile,other patients were treated with single needling as control. The patients' joint pain,tenderness,swelling,dysfunction index,gripping force,morning stiffness,walking time of 20 meters,rheumatoid factor,erythrocyte sedimentation rate,C response protein,IgG,IgA,and IgM were measured before and after treatments.Results:Warm needling could improve the rheumatoid arthritis patients' symptoms,and had an effective rate of 86.2%,while the single needling had an effective rate of 57.1%(P＜0.01). And the therapeutic effects were related to the disease duration and condition.
