Abstract： 目的 研究中药黄连解毒汤(HLJDT)对人多发性骨髓瘤(MM)细胞RPMI8226增生和凋亡的作用.方法 以含10%胎牛血清的RPMI1640培养基常规培养RPMI8226细胞,分别以不同浓度的HLJDT作用不同的时间后,应用锥虫蓝拒染法测定细胞活力变化,MTT法检测细胞的增生变化;采用流式细胞术测定细胞周期的变化;应用流式细胞仪检测药物细胞的凋亡现象,荧光显微镜下观察AO/EB染色后的细胞凋亡形态变化;比色法检测半胱氨酸蛋白水解酶3(caspase3)活性变化.结果 与对照组相比,200～800 ng/ml浓度的HLJDT可明显抑制细胞增生影响(P＜0.01),并呈时间和剂量依赖性;使G0/G1期细胞增多,S期细胞减少,并呈剂量依赖性改变;MM细胞凋亡百分率显著增高(P＜0.01),免疫荧光显微镜下可见典型的凋亡细胞形态学变化;使caspase3活性增强,且呈剂量和时间依赖性(P＜0.01).结论 HLJDT能有效抑制MM细胞RPMI8226增生,促其凋亡,G0/G1期细胞比例增加和S期细胞比例减少可能是原因之一;caspase3活性增强可能参与其凋亡过程,具体机制还有待研究.
