Objective:To evaluate the clinical effects of bloodletting cupping therapy(BCT)for patients with postherpetic neuralgia.Methods:We comprehensively searched four Chinese databases(Wanfang,China National Knowledge Infrastructure,VIP Database for Chinese Technical Periodicals,China Biology Medicine disc)and foreign databases(Pubmed,Cochrane Library).The retrieval time was from the build-up time to May 2018.RevMan 5.3 software was used for statistical analysis.Results:We finally obtained 18 eligible studies.Compared with routine western medicine,BCT can significantly improve PHN(OR=7.45,95%CI,3.36-16.51,Z=4.95,P<0.01).BCT plus other methods of acupuncture with fire needle and filiform needle has significant therapeutic effect(OR=5.54,95%CI,3.01-10.19,P<0.01),BCT plus routine western medicine has significant therapeutic effect(OR=4.99,95%CI,2.73-9.11,P<0.00001).Conclusion:It showed that the therapeutic effects of BCT,BCT plus other acupuncture methods with fire needle and filiform needle,and BCT combined with western medicine are better than those treated with single western medicine.It is effective to treat postherpetic neuralgia with Bloodletting Cupping Therapy.
