摘　　要：BACKGROUND： Ceramide galactosyltransferase （CGT） protein and mRNA expression defect can cause the abnormal morphology and slowing conduction velocity of peripheral nerve. Morphologic change and functional disorder of myelin sheath and axon appear when diabetic peripheral neuropathy （DPN） occurs. Whether electroacupuncture at Zusanfi（ST 36） and Shenshu（BL 32） points can enhance the expression of CGT protein and mRNA in the DPN tissue？ OBJECTIVE： To observe the effect of electroacupuncture at Zusanfi and Shenshu points on motor, sensory conduction velocity and CGT mRNA and its protein expression of sciatic nerve in rats with DPN. DESIGN： A randomized and controlled animal experiment SETTING ： Department of Neurology and Central Laboratory, Yueyang Hospital of Traditional Chinese ＆ Western Medicine, Shanghai University of Traditional Chinese Medicine. MATERIALS ： Totally 60 healthy male Wistar rats of clean grade, aged 4 month, with body mass of 200 to 220 g, were enrolled in this study. Streptozotocin （STZ, Sigma Company of USA, Batch No. S-0130）. METHODS： This study was carried out in the Animal Experimental Center and Central Laboratory, Yueyang Hospital of Traditional Chinese ＆ Western Medicine during February 2005 to March 2006. （1） Fifteen rats were randomly chosen,serving as normal group.AU the other rats were intraperitoneally injected once with STZ to develop experimental diabetic rat models. If fasting blood glucose was ≥ 15 mmol/L,sensory nerve and motor nerve conduction velocity of sciatic nerve was obviously slowed, tail-swaying temperature threshold was increased and myelinated nerve fiber of sciatic nerve changed, DPN models were successful. The successful model rats were randomly assigned into 3 groups： model group, control group（electroacupuncture at non-meridian-non-acupoint）and electroacupuncture group [electroacupuncture at Zusan/i and Shenshu points], with 15 rats each. The rats in the normal group and model group were untouched.
