中文摘要： 针康法作为脑卒中康复常用方法，临床疗效确切，其作用机制尚不十分清楚。我们前期研究发现，针康法能促进脑缺血后神经血管单元重构，对神经元/血管都起到保护作用。是否存在某共同靶点介导针康法对神经元、血管的保护作用，是本课题关注的问题。本项目拟在脑缺血动物模型上，观察针康法干预后神经元、血管内皮细胞凋亡的情况；在体沉默脑内cIAP1，采用尼氏染色、电镜、免疫印记等方法观察针康法干预后各实验组神经元、微血管及其分子标志物的变化；体外建立神经元、血管内皮细胞氧糖剥夺（OGD）模型，沉默cIAP1基因，给予BDNF处理模拟针康法的体外效应，观察各实验组细胞损伤情况及神经血管分子标志物的变化。从体内外两方面验证cIAP1是针康法诱导神经元保护、血管保护的共同靶点这一假说，为针康法临床推广应用提供理论依据。

英文摘要： The clinical effect of acupuncture-rehabilitation method is precise and wide applied in stroke rehabilitation,but the mechanism has not been elucidated. Acupuncture-rehabilitation method can regulate nerve vascular unit reconstruction after cerebral ischemia,protecting neurons/vessels in preliminary studies.Whether there is a shared molecule underlying acupuncture-rehabilitation method induce protection in neurons and vascular endothelial cells remains unknown? The neurons and vascular endothelial cell apoptosis will be observed after acupuncture-rehabilitation method situation in cerebral ischemia animal model in this study;CIAP1 silent in brain,the changes of neurons and microvessels and their molecular markers will be observed after acupuncture-rehabilitation method situation by Nissl staining, electron microscopy and immunoblotting methods in each experimental groups.The oxygen glucose deprivation (OGD) models in neurons and vascular endothelial cells are made in vitro. cIAP1 genes silent by the lentiviral vector system to mediate and BDNF gived to analog acupuncture-rehabilitation method effect in vitro, the changes of neurons and microvessels and their molecular markers will be observed. The hypothesis thatcIAP1 is a shared molecule underlying acupuncture-rehabilitation method induced protection in neurons and vascular endothelial cells against cerebral ischemia will be proved in vivo and vitro, providing the theory basis for acupuncture-rehabilitation method applied in clinical.
