血管内皮是介于循环血液与血管平滑肌之间的生理屏障,而且具有重要内分泌功能,通过释放内皮源性舒张因子一氧化氮(NO)及缩血管因子(ET)等血管活性物质,在维持血管舒缩方面起着关键作用。大量研究表明,血管内皮功能损伤及功能障碍是许多疾病的早期事件[1]。正常血管内皮主要功能 Endothelium is a physiological barrier between circulating blood and vascular smooth muscle, and has important endocrine function. By releasing the vasoactive substances such as endothelium-derived relaxing factor nitric oxide (NO) and vasoconstrictor (ET) Shrinkage plays a key role. Numerous studies have shown that vascular endothelial dysfunction and dysfunction are early events in many diseases [1]. The main function of normal vascular endothelial
