摘要: 缺血缺氧预适应现象最初见于心脏,一经发现即引起了学术界的广泛关注,随后研究者分别从不同层面证实了大脑同样具有预适应现象,并进行了大量的研究,成为抗脑缺血缺氧研究的热点。脑缺血缺氧预适应(cerebral ischemia/hypoxia preconditioning,CIP)可以通过多种信号传导途径,减少细胞凋亡,提高机体抗氧化能力,减少氧化损伤,升高低氧诱导因子和热休克蛋白HSP70的生成等,各种机制相互联接,相对独立。

Abstract: The phenomenona of ischemia/hypoxia preconditioning were first discovered in heart. Numerous studies,carried out at different levels,have confirmed that there are also preconditioning phenomenona in brain,and the phenomenona of ischemia/hypoxia preconditioning in brain have become a hot topic in the field of ischemia and hypoxia. Cerebral ischemia/hypoxia preconditioning (CIP) can decrease cell apoptosis,increase the anti-oxidant ability and decrease oxidant injury,increase the generation of hypoxic inducible factor-1 and heat shock protein 70 through multiple signal transduction pathways. There are interactions among the mechanisms about CIP which are relatively independent.

Key words: ischemia hypoxia preconditioning, apoptosis, reactive oxygen species, signal transduction, hypoxic inducible factor, heat shock proteins
