Abstract: Remote ischemic postconditioning (RIPostC) refers to the ability to activate the endogenous protective mechanism of the body to reduce the ischemia-reperfusion injury of important organs by giving rapid and intermittent stimulation of limb blood flow interruption after reperfusion. Early reperfusion treatment is the main method for the treatment of ischemic vascular disease, but a large number of studies and clinical evidences show that the recovery of blood perfusion and oxygen supply of some ischemic tissues and organs aggravates the tissue damage, i.e. ischemia-reperfusion injury, including myocardial ischemia/reperfusion (I/R) injury, such as arrhythmia, myocardial systolic and diastolic dysfunction, metabolic abnormality, myocardial ultrastructural changes, and increased cerebral infarction area. Studies at home and abroad have found that remote ischemic postconditioning can reduce the reperfusion injury of heart, brain, kidney, and other important organs. In order to deal with the challenge of reducing reperfusion injury, remote ischemic postconditioning has become a hot topic in clinical research.

摘要: 远隔缺血后适应(remote ischemic postconditioning,RIPostC)是指在再灌注后通过给予快速、间断性的肢体血流中断刺激,调动机体内源性保护机制以减轻重要器官缺血再灌注损伤的能力。早期再灌注治疗是缺血性血管病治疗的主要手段,但大量研究及临床证据表明:恢复某些缺血组织器官的血液灌注及氧供反而加重组织损伤即缺血-再灌注损伤,包括心肌缺血/再灌注(ischemia/reperfusion,I/R)损伤如心律失常、心肌舒缩功能障碍、代谢异常以及心肌超微结构的改变及脑梗死面积增大等损伤。国内外研究发现远隔缺血后适应具有减轻心、脑、肾等重要器官再灌注损伤的作用。为应对减轻再灌注损伤这一挑战,远隔缺血后适应目前成为临床研究的热门话题。因此尽快恢复组织器官的血流灌注是缺血性血管病最为重要的治疗方案,其中包括溶栓治疗、经皮冠状动脉介入治疗等手段。但是恢复器官血流灌注后所致的再灌注损伤又是临床治疗的一大难题,其中心脏及脑对血流灌注及氧供需求高,极易发生缺血-再灌注损伤,因此探究减轻再灌注损伤成为了缺血性血管病研究热门话题。
