摘要： 目的观察电针联合依达拉奉对糖尿病周围神经病大鼠坐骨神经传导速度和氧化应激的影响。方法SD大鼠60 只，选取10 只作为正常组。其余予一次性链脲佐菌素腹腔注射造模。抽取48 只模型大鼠，分为电针组、依达拉奉组、联合组和模型组各12 只。造模后4 周、8 周，测试各大鼠摆尾阈值、血清超氧化物酶歧化酶(SOD)活性和丙二醛(MDA)浓度及坐骨神经传导速度。结果造模8 周时，电针组、依达拉奉组和联合组运动神经传导速度明显高于模型组(P<0.01)，SOD 活性明显高于模型组(P<0.01)，MDA 浓度明显低于模型组(P<0.01)；而联合组明显优于电针组、依达拉奉组(P<0.01)。结论电针及依达拉奉均能有效抑制糖尿病周围神经病大鼠的氧化应激反应，改善坐骨神经传导速度，联合应用效果更佳。

Abstract: Objective To observe the effects of electroacupuncture combined with edaravone on the conduction velocity of sciatic nerve and oxidative stress in rats with diabetic peripheral neuropathy. Methods 60 Sprague Dawley (SD) rats were included. 10 of them were selected as normal group. The other rats were modeled as diabetic peripheral neuropathy with streptozotocin. 48 of them were randomly selected and divided into electroacupuncture group (n=12), edaravone group (n=12), electroacupuncture + edaravone group (n=12), and model group (n=12). The threshold temperature for wave tail was tested, the levels of superoxidase dismutase (SOD) and malonaldehyde (MDA) were determined, and the conduction velocity of sciatic nerve were measured, before, and 4 and 8 weeks after modeling. Results 8 weeks after modeling, the conduction velocity and SOD increased in the electroacupuncture group, edaravone group and electroacupuncture+edaravone group compared with the model group (P<0.01), with the MDA decrease (P<0.01), while it was improved more in the electroacupuncture+edaravone group than in the electroacupuncture group or the edaravone group (P<0.01). Conclusion Both electroacupuncture and edaravone can inhibit oxidative stress and improve nerve conduction velocity of the sciatic nerve in rats with diabetic peripheral neuropathy, and it is more effective of combination.
