Objective To observe the clinical effects of treating diabetic peripheral neuropathy（DPN）with the acupuncture point injection of the Chinese medicine in combination with lipoic acid.Method To divide 66 cases of DPN patients into two groups randomly.Patients of the control group were treated with lipoic acid while their blood sugar level was under control.Patients of the experiment group were treated in the same way plus receiving acupuncture point injection of 1.0mL Danshen injection.Both groups were treated 30 d

and compare and observe the clinical effect and the changes of their electromyography（EMG）by testing the nerve conduction velocity of their bilateral median nerve and common peroneal nerve with full range functional EMG evoked potentiometer before and after the treatment.Results The comparative differences in the nerve conduction velocity of the two groups before treatment saw no statistical significance.Aftermath the treatment

the nerve conduction velocity of the experiment group was superior to that of the control group（P<0.05）.Within each group

the post-treatment nerve conduction velocity of the patients was superior to that of the pretreatment level（P<0.05）.Conclusion The acupuncture point injection in combination with lipoic acid can markedly improve the nerve conduction velocity of DPN patients and enhance the clinical effects.
