RESUMEN
Objective To systematically retrieve and integrate the clinical randomized controlled trials(RCTs)and systematic reviews/Meta-analyses of traditional Chinese medicine in the treatment of diabetic peripheral neuropathy(DPN)in recent 10 years,aiming to summarize the overall evidence distribution of traditional Chinese medicine in the treatment of DPN.Methods CNKI,WANFANG,VIP,CBM,PubMed,Web of Science,Embase and the Cochrane Library were used as retrieval database.The retrieval time was from January 1,2012 to October 23,2022.RCTs and systematic reviews/Meta-analyses were included.The distribution of evidence was displayed in the form of charts.AMSTAR-1 was used for the methodological quality evaluation of systematic reviews/Meta-analyses.Results A total of 1648 RCTs and 59 systematic reviews/Meta-analyses were included.The overall number of RCTs were on the rise,but most of the scale of the RCTs were relatively small,with 68％of the samples size of a single study concentrated between 50-100;The Duration of intervention was 4-8 weeks;Multi-therapy was the most commonly used intervention,among which the most involved intervention was the combination of TCM decoction;Traditional Chinese medicine monotherapy was mainly oral traditional Chinese medicine decoction.The evaluation indexes of clinical efficacy paid much attention to the total effective rate,nerve conduction velocity,TCM diseases and syndromes;economic index,quality of life,long-term efficacy and other indicators had attracted less attention of researchers.The overall methodological quality of systematic reviews/Meta-analyses was not high,most of which show good clinical efficacy,but lack sufficient evidence support.Conclusion The research results show that the treatment of diabetes peripheral neuropathy with TCM have good characteristics and advantages,the shortcomings are mainly reflected in the low quality of the overall methodology of systematic reviews/Meta-analyses.Suggesting that more high-quality clinical RCTs with breadth and depth are still needed in the future to verify the characteristics and advantages of traditional Chinese medicine in the treatment of diabetic peripheral neuropathy and provide data information support for evidence-based medicine.
