血管内皮细胞能分泌多种活性物质,对维持血管壁的张力和血液的流动具有重要作用,是功能活跃的代谢细胞之一。血管内皮功能障碍主要表现为内皮依赖性舒张功能障碍,是动脉粥样硬化病理过程的始动环节,早期阻止或延缓血管内皮功能障碍的发生发展,对血管内皮进行长效保护已成为心血 Vascular endothelial cells can secrete a variety of active substances, to maintain the vascular wall tension and blood flow has an important role, is one of the active metabolic cells. Vascular endothelial dysfunction is mainly manifested as endothelium-dependent dystonic dysfunction, is the first step in the pathological process of atherosclerosis, early to prevent or delay the occurrence and development of vascular endothelial dysfunction, long-term protection of the vascular endothelium has become effort
