  • Descrição: This study aimed to explore the efficacy and safety of Tangmaikang Granules in the treatment of diabetic peripheral neuropathy(DPN). PubMed, Cochrane Library, EMbase, SinoMed, CNKI, Wanfang and VIP were retrieved for randomized controlled trial(RCT) of Tangmaikang Granules in the treatment of DPN. Cochrane handbook 5.3 was used to evaluate the quality of the inclu-ded studies, and RevMan 5.4.1 and Stata 15.1 were employed to analyze data and test heterogeneity. GRADEpro was used to assess the quality of each outcome index. Clinical effective rate was the major outcome index, while the improvement in numbness of hands and feet, pain of extremities, sluggishness or regression of sensation, sensory conduction velocity(SCV) and motor conduction velocity(MCV) of median nerve and peroneal nerve, fasting blood glucose(FBG), 2 h postprandial blood glucose(2hPBG), and glycated hemoglobin(HbA1c) and incidence of adverse reactions were considered as the minor outcome indexes. A total of 19 RCTs with 1 602 patients were eventually included. The Meta-analysis showed that the improvements in clinical effective rate(RR=1.45, 95%CI[1.32, 1.61], P<0.000 01), pain of extremities(RR=1.70, 95%CI[1.27, 2.27], P=0.000 3), MCV of peroneal nerve(MD=4.08, 95%CI[3.29, 4.86], P<0.000 01) and HbA1c(SMD=-1.23, 95%CI[-1.80,-0.66], P<0.000 1) of Tangmaikang Granules alone or in combination in the experimental group were better than those in the control group. Compared with the conditions in the control group, numbness of hands and feet(RR=1.42, 95%CI[1.12, 1.80], P=0.003), sluggishness or regression of sensation(RR=1.41, 95%CI[1.05, 1.91], P=0.02), SCV of median nerve(MD=4.59, 95%CI[0.92, 8.27], P=0.01), SCV of peroneal nerve(MD=4.68, 95%CI[3.76, 5.60], P<0.000 01) and MCV of median nerve(MD=5.58, 95%CI[4.05, 7.11], P<0.000 01) of Tangmaikang Granules in combination in the experimental group were improved by subgroup analysis. The levels of FBG(MD=-0.57, 95%CI[-1.27, 0.12], P=0.11) and 2hPBG(MD=-0.69, 95%CI[-1.70, 0.33], P=0.18) in the experimental group were similar to those in the control group after treatment with Tangmaikang Granules alone or in combination. There was no difference in the safety(RR=1.28, 95%CI[0.58, 2.82], P=0.54) of Tangmaikang Granules in the treatment of DPN between the experimental group and the control group. Tangmaikang Granules could significantly increase clinical effective rate and nerve conduction velocity as well as improve symptoms of peripheral nerve and blood glucose level, and no serious adverse reactions were identified yet. Further validation was needed in future in large-sample, multicenter, high-quality RCTs.
