Objective:To observe the efficacy of warm needling moxibustion plus intra-articular injection of sodium hyaluronate for hip involvement in ankylosing spondylitis(AS).Methods:A total of 60 patients with hip involvement in AS were randomly divided into a control group and an observation group,with 30 cases in each group.The patients in the control group were given an intra-articular injection of sodium hyaluronate,once a week.The patients in the observation group were given additional warm needling moxibustion,once a day,with a 2-day interval after five consecutive days of treatment.After 5 weeks,changes in such indicators as visual analog scale(VAS)score,Harris score,Bath ankylosing spondylitis disease activity index(BASDAI),Bath ankylosing spondylitis functional index(BASFI),serum cartilage oligomeric matrix protein(COMP),interleukin(IL)-17 were observed,and the efficacy was evaluated.Six months after treatment,Bath ankylosing spondylitis radiology index-hip(BASRI-hip)was evaluated.Results:After treatment,the total effective rate in the observation group was higher than that in the control group(P<0.05).After treatment,the VAS scores in both groups were lower than those before treatment(P<0.05),and the score of the observation group was lower than that of the control group(P<0.05).After treatment,the Harris scores of both groups were higher than those before treatment(P<0.05),and the score of the observation group was higher than that of the control group(P<0.05).Six months after treatment,the BASRI-hip score of the control group was higher than that before treatment(P<0.05),while the score of the observation group was not significantly different from that before treatment(P>0.05)and was lower than that of the control group(P<0.05).After treatment,the scores of BASDAI and BASFI of both groups were lower than those before treatment(P<0.05),and the scores of the observation group were lower than those of the control group(P<0.05).After treatment,the levels of serum COMP and IL-17 of both groups were lower than those before treatment(P<0.05),and the levels of the observation group were lower than those of the control group(P<0.05).Conclusion:The efficacy of warm needling moxibustion plus intra-articular injection of sodium hyaluronate for hip involvement in AS is better than the intra-articular injection of sodium hyaluronate alone.This combined approach can alleviate hip pain,improve hip functions,delay the destruction of the hip,prevent AS development,and reduce the levels of serum COMP and IL-17. 展开更多
