ObjectiveTo investigate the effect of needle warming moxibustion treating rheumatoid arthritis(RA,Tongbi) and its impact on TNF－α,IL－6 and IL－37.MethodsFrom September 2013 to January 2017,92 patients diagnosed with cold－damp obstruction type of RA were included in our hospital and were randomly divided into two groups on the basis of the random data table method.The control group (n=46) receivedwestern medicine only,while the observation group(n=46)received needle warming moxibustion treatment.Furthermore,the clinical efficacy and inflammatory factors were compared.ResultsAfter treatment,the level of TNF－α,IL－6 and IL－37 in the two groups were decreased,and those indexes in the observation group were significantly decreased than those in the control group (P＜0.05).The number of joints swelling and joint tenderness were decreased in both groups,and the indexes in the observation group were significantly fewer than those in the control group (P＜0.05).The total effective rate of the observation group was 93.48%, which was significantly higher than the control group (76.09%)(P＜0.05).Conclusion Needle warming moxibustion treating RA is effective and can improve the inflammatory response,thus it is worthy of popularization.
