关于心脏骤停猪模型复苏后 Alda-1 使用抑制铁死亡对脑损伤的研究

马 桂琴, 丁 磊

摘要

本研究深入探讨了心脏骤停(Cardiac Arrest, CA)后猪模型在经历心肺复苏(Cardiopulmonary Resuscitation, CPR)后,
其脑氧微循环系统中铁死亡(Ferroptosis)的发生机制及其对脑组织损伤的影响。研究通过构建稳定的 CA-CPR 猪模型,
结合生化检测、组织病理学分析及先进的分子生物学技术,详细评估了乙醛脱氢酶 2(Aldehyde Dehydrogenase 2, ALDH2)
特异性激活剂 Alda-1 在减轻复苏后脑损伤中对铁死亡过程的调控作用。结果显示,Alda-1 的干预显著减轻了心脏骤停后
猪模型复苏过程中的脑组织损伤程度,这一保护作用可能与抑制长链脂酰辅酶 A 合成酶 4(ACSL4)以及上调谷胱甘肽过
氧化物酶 4(GPx4)的表达,进而阻断由铁死亡信号通路所介导的脑细胞程序性死亡过程有关。
