Peripheral nerve injury(PNI)is a common-seen disease in clinic,which belongs to the category of “Bi syndrome” or “Flaccidity syndrome” in TCM.By following the research approach of “evaluating the efficacy,finding the regularity,clarifying the mechanism and guiding the clinical practice”,our team,led by Professor GUO Yi,cooperating with the team of Professor Ishida Torao from Suzuka University of Medical Science,carried out a series of studies on the electroacupuncture(EA)treatment of PNI.We confirmed the effects of EA on peripheral nerve regeneration and muscle atrophy caused by denervation.Better results can be obtained from the early treatment and low frequency of EA.We also found the transcutaneous acupoint electrical stimulation(TAES)can relieve the clinical symptoms and improve the life quality of diabetics by improving the motor and sensory functions of the injured peripheral nerve.The mechanism by using morphological and molecular biological technology is clearly defined.The study provided the scientific basis for the better use of EA for PNI,and promoted the clinical application of EA for the treatment of PNI.
