Methods: 138 cases of patients with diabetic peripheral neuropathy who were treated in endocrinology department of our hospital between June 2014 and October 2016 were enrolled and randomly divided into two groups. The combination group received Xueshuantong combined with antioxidant drug therapy, and the control group received antioxidant drug therapy. Before and after treatment, the nerve conduction velocity as well as serum content of oxidative stress indexes and nerve cytokines was measured.Results: 4 weeks and 8 weeks after treatment, common peroneal nerve and median nerve MNCV and SNCV as well as serum SOD, GSH-Px, HO-1, CAT, CNTF, BDNF and SDF-1 levels of both groups were significantly higher than those before treatment while serum MDA, AOPP and 8-OHdG levels were significantly lower than those before treatment, and common peroneal nerve and median nerve MNCV and SNCV as well as serum SOD, GSH-Px, HO-1, CAT, CNTF, BDNF and SDF-1 levels of combination group were significantly higher than those of control group while serum MDA, AOPP and 8-OHdG levels were significantly lower than those of control group.Conclusion:Xueshuantong combined with antioxidant drugs can improve the nerve conduction function, inhibit oxidative stress response and improve neurotrophy status in patients with diabetic peripheral neuropathy.展开更多
