摘要:

背景 七氟醚作为一种常用的吸入性麻醉药,被广泛应用于全身麻醉。近年来,许多研究表明,七氟醚后处理可以保护脑组织对抗脑缺血/再灌注(ischemia/reperfusion, I/R)损伤,其作用机制是多方面的,主要包括增强脑的抗缺血能力,减少脑梗死体积和脑水肿程度,减轻脑细胞氧化应激、炎症反应,抑制脑细胞的凋亡。其中,抑制脑细胞的凋亡扮演了重要的角色。 目的 就七氟醚后处理脑保护作用相关的细胞凋亡信号转导通路进行综述。 内容 重点阐述七氟醚后处理的脑保护作用及其对细胞凋亡的线粒体途经和内质网应激(endoplasmic reticulum stress, ERS)途经信号转导通路的调控。 趋向 更好地了解七氟醚后处理脑保护作用的分子机制,从而为临床脑I/R患者的早期治疗提供指导。

Abstract:

Background As a commonly used volatile anesthetics, sevoflurane has been widely used for general anesthesia in clinic. In recent years, many studies have shown that postconditioning with sevoflurane can protect cerebral tissue from ischemia/reperfusion injury but the underlying mechanism is complicated, mainly includes enhancing tolerance of brain tissue to ischemia/reperfusion (I/R), reducing cerebral infarction volume and cerebral edema, reducing oxidative stress and inflammatory response of brain cells, and inhibiting apoptosis of brain cells. Among various mechanisms, inhibition of cell apoptosis plays a key role in the protective effect. Objective Summarizing the signal transduction pathway of cell apoptosis that related to the neuroprotection of postconditioning with sevoflurane. Content This study reviewed the neuroprotective effect of sevoflurane postconditioning and its regulation on signal transduction about mitochondria-associated and endoplasmic reticulum stress(ERS)-associated apoptosis. Trend To better understand the molecular mechanism of neuroprotection of sevoflurane postconditioning and provide a guidance for treatment of patients with cerebral I/R.
