细胞凋亡是生物体调节细胞群体相对恒定的一种重要方式,近年来成为生命科学中的研究热点。目前认为肿瘤的发生是细胞丧失自发调节凋亡反应能力的最终结果。凋亡是肿瘤细胞死亡的一种重要形式,放化疗可诱导肿瘤细胞发生凋亡,并加速细胞凋亡过程而使更多的肿瘤细胞死亡,从而使肿 Apoptosis is an important way for organisms to regulate cell population relatively constant, and has become a research hot spot in life science in recent years. It is currently believed that the occurrence of tumors is the end result of the cells losing the ability to spontaneously regulate apoptotic response. Apoptosis is an important form of tumor cell death, radiotherapy and chemotherapy can induce apoptosis of tumor cells and accelerate the process of apoptosis and make more tumor cells die, so swollen
