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
