脑缺血再灌注损伤是临床经常遇到的问题,也是脑缺血患者死亡和致残的重要原因,涉及一系列复杂的机制。缺血所诱导的神经细胞凋亡,在缺血后脑损伤中起着重要作用。近几年来,脑缺血后的再灌注损伤受到广泛关注,缺血半暗带的脑保护治疗是治疗再灌注损伤的重点,其中细胞凋亡更是研 Cerebral ischemia-reperfusion injury is a common clinical problems, but also an important cause of death and disability in patients with cerebral ischemia, involving a series of complex mechanisms. Ischemia-induced neuronal apoptosis plays an important role in ischemic brain injury. In recent years, reperfusion injury after cerebral ischemia has received widespread attention, ischemic penumbra brain protection treatment is the focus of reperfusion injury, apoptosis is more research
