血管内皮细胞(EC)位于血管内膜表面,具有抗血栓形成及选择通透性等生理功能。动脉内皮长期反复受损是动脉粥样硬化(AS)病变形成的始动环节。保护EC免受损伤是防止AS发生发展的关键。国外的研究表明,血液中过量的低密度脂蛋白(LDL)是引起内皮损伤 Vascular endothelial cells (ECs) are located on the surface of vascular intima and have physiological functions such as antithrombosis and selective permeability. Prolonged and repeated damage to the arterial endothelium is the first step in the development of atherosclerotic lesions. Protection of EC from injury is the key to preventing the development of AS. Foreign studies have shown that excess blood LDL (LDL) is caused by endothelial damage
