To explore the effects of warm acupuncture on nerve conduction and blood glucose metabolism in patients with diabetic peripheral neuropathy(DPN).Methods:A total of 80 patients with DPN in The Third Affiliated Hospital of Inner Mongolia Medical University from January 2016 to January 2018 were selected and randomly divided into an observation group(40 cases)and a control group(40 cases).The control group was given the hypoglycemic drugs acarbose tablets and methylcobalamin tablets.The observation group was given warm acupuncture on basis of the control group.The level of glucose，never conduction and score of toronto were compared between 2 groups.Results:The total effective rate was 85.00% in the observation group and 70.00% in the control group，with significant difference(P<0.01).Compared with before treatment，the levels of fasting blood glucose，2 h postprandial blood glucose and scores of toronto in the 2 groups decreased after treatment(P<0.05)，and those levels and toronto scores in the observation group were significantly lower than those in the control group(P<0.05).After treatment，the sensory conduction velocity of median nerve and common peroneal nerve in the 2 groups increased，with significant difference compared with before treatment(P<0.05)，and those indicators in the observation group were significantly higher than those in the control group(P<0.05).Conclusion:Warm acupuncture can improve the sensory conduction velocity of median nerve and common peroneal nerve by lowering the levels of fasting blood glucose，2 h blood glucose and toront score in patients with DPN.It has better curative effect than mecobalamin tablets and has clinical application value.
