细胞凋亡（ａｐｏｐｔｏｓｉｓ）是机体在维持正常组织结构和生理功能过程中自然发生的细胞更替，它的异常可导致很多疾病，促进细胞凋亡可使正常细胞过多死亡，同样阻滞细胞凋亡的发生则可能导致恶性肿瘤。最近的研究表明细胞凋亡在正常和病变再塑形的血管壁中均起重要作用［ Apoptosis is the natural replacement of the body in the process of maintaining normal tissue structure and physiological function. Its abnormality can lead to many diseases, and the promotion of apoptosis can lead to excessive death of normal cells, as well as blocking apoptosis. The occurrence of this may lead to malignant tumors. Recent studies have shown that apoptosis plays an important role in normal and pathological remodeling of the vascular wall [
