急性脑缺血后继发性神经损伤的机理及防治是近年人们关注的热点问题。研究有效的神经保护剂 ,并掌握有效的治疗时间窗 ,阻止缺血半暗带的损伤进展是人们研究的热点 ,可能成为治疗缺血性脑卒中的突破口。脑缺血损伤的机制复杂 ,多因素参与神经元的损伤。目前 ,无论是动物模型研 The mechanism and prevention and cure of secondary nerve injury after acute cerebral ischemia are the hot issues that people pay attention to in recent years. To study effective neuroprotective agents and to master the effective treatment time window to prevent the progression of ischemic penumbra is a hot research topic and may become a breakthrough in the treatment of ischemic stroke. The mechanism of cerebral ischemic injury is complex, and many factors involved in neuronal damage. At present, whether it is animal model research
