摘要: 脑缺血预处理是指给予脑组织一个低于阈值的缺血缺氧刺激,激活机体的内源性保护因子或信号通路,从而产生脑缺血耐受的现象。预处理涉及的神经保护机制包括抗凋亡、抗氧化应激、抑制炎症反应、调节兴奋性/ 抑制性神经递质、血管重塑、保护血脑屏障、维持能量代谢/ 线粒体膜电位以及激活DNA 修复和自我修复等作用。而氧化应激损伤、自由基连锁反应是缺血再灌注损伤的核心病理环节,该文对内源性抗氧化应激机制在缺血预处理引起的再灌注损伤中作用进行综述,为缺血缺氧性脑病的临床治疗提供理论依据。

Abstract: Cerebral ischemic preconditioning (CIP) induced by sublethal transient cerebral ischemia could increase the tolerance of the brain tissue to subsequent lethal ischemia by activating the endogenous protective factor or signaling pathways. Establishing such a tolerance involved multiple mechanisms:resistance to apoptosis,antioxidant stress,inhibiting the inflammatory response,adjusting the excitatory and inhibitory neurotransmitter,vascular remodeling,protecting blood brain barrier,maintaining energy metabolism and mitochondrial membrane potential and activating the DNA repair and self-repair etc. However,oxidative stress damaging,free radical chain reacting is the core of ischemia-reperfusion injury. Therefore,a better understanding of the mechanism of cerebral ischemic preconditioning and endogenous antioxidant stress in the ischemia reperfusion injury could provide theoretical basis for clinical treatment of ischemia anoxic encephalopathy.

Key words: cerebral ischemic preconditioning, ischemia reperfusion injury, endogenous antioxidant stress, signaling pathways
