〔摘要〕 动脉粥样硬化、冠心病等心血管疾病的病理生理基础是病理性血管重构,而血管内皮细胞(vascular endothelial cell, VEC)功能障碍是病理性血管重构的始动环节。VEC是锚定在基底层、与血液成分和细胞直接接触的单层细胞,是氧化应激、活性氧及其相关信号通路的作用靶点。近年来,中药在治疗心血管疾病方面卓有成效,许多中药复方、中药提取物可通过抗氧化作用保护VEC,调节心血管疾病的发生发展。本文对近年来中药及复方改善VEC氧化应激损伤的作用及其相关机制的研究进行总结,为推动其抗氧化研究及应用提供参考。

〔Abstract〕 Pathological vascular remodeling (PVR) is the pathophysiological basis of cardiovascular diseases such as atherosclerosis and coronary heart disease, The initial link of PVR is vascular endothelial cell (VEC) dysfunction. VEC is monolayer endothelial cell, which is anchored in the basal layer and direct contact with components and cells from blood, as the targets of oxidative stress, reactive oxygen species and their related signaling pathways. In recent years, traditional Chinese medicine (TCM) has made great achievements in the treatment of cardiovascular diseases. Many compound prescriptions and the bioactive ingredients of TCM can protect VEC by antioxidant effects, and regulate the occurrence and development of cardiovascular diseases. In this paper, we summarized the researches on the effects of TCM and compound prescriptions on VEC oxidative stress injury and its related mechanisms in recent years, and provided a reference for promoting its antioxidant research and application.

动脉粥样硬化(atherosclerosis, AS)、冠心病等心血管疾病是人类主要的死亡原因之一,虽然心血管疾病病因不同,但病理性血管重构是其共同的病理生理基础,其中一个重要的病理机制是氧化应激(oxidative stress, OS)[1]。OS是由活性氧(reactive oxygen species, ROS)过度生成及其消除不平衡引起,反过来OS也可进一步引发ROS的代谢失衡,导致ROS累积,通过直接氧化细胞蛋白、脂质和DNA或通过死亡信号通路而引起细胞损伤,导致内皮完整性丧失、屏障功能障碍、血管舒缩调节异常、血流动力学改变,引发心血管事件[2]。血管内皮细胞(vascular endothelium cell, VEC)是锚定在基底层的单层内皮细胞,构成动脉、静脉和毛细血管管壁的最内层结构,与血液成分和细胞直接接触[3],具有维持内环境稳态、营养交换、宿主防御反应和血管舒张等多种功能[4],是ROS及其相关信号通路的作用靶点。……
