脑卒中患者中医辨证与视觉诱发电位的相关研究

Study on syndrome-type in TCM and its correlation with visual evoked potentials in patients with stroke

目的:探讨脑卒中各中医证型与视觉诱发电位(VEP)的关系。方法:38例脑梗死患者辨证分为肝阳上亢组18例和其他证型组20例,正常组为健康人15例,均采用Nicolet Viking IV型肌电诱发电位仪检测VEP,刺激模式为全视野黑白棋盘格翻转图形双眼分别刺激。结果:与正常组及其他证型组比较,肝阳上亢组VEPP100潜伏期延长(P<0.05),VEP异常率较高,差异有统计学意义(P<0.05,P<0.01)。结论:脑卒中肝阳上亢型VEP存在异常改变,可作为脑卒中中医辨证分型和中医治疗的客观指标。

Objective：To explore the possible relationship between syndrome-type in TCM of cerebral infarction and the visual evoke potentials.Methods：38 cases of cerebral infarction were divided into hver yang type group and syndrome-type control group. The normal control group consisted of 30 healthy cases, Visual evoked potentials were recorded by Nicolet Viking Ⅳ in all cases.Results：In liver yang type group,the latencies of PIO0 peaks were prolonged compared with the control group.Conclusion：Visual evoked potentials were correlated with the syndrome-types of patients with cerebral infaretion. It would be valuable for diagnosis and treatment of cerebral infarction in TCM.
