摘要 目的观察益气养阴方的含药血清与低浓度的顺铂(DDP)体外共同作用于肝癌HepG2细胞后,对HepG2细胞Sur-vivin表达的影响,从而探讨本益气养阴方与化疗合用治疗肝癌的协同增效作用的相关机制。方法运用血清药理学方法制备大鼠的益气养阴方的含药血清,分为中药含药血清组、化疗药物DDP组和中药含药血清+DDP组,并设不含药的空白大鼠血清为对照组,分别作用于HepG2细胞,应用SP免疫细胞化学染色法及western-blot检测各组细胞24h、48h、72h后Survivin蛋白的表达变化。结果各组作用24,48,72 h后,中药含药血清组HepG2细胞Survivin蛋白的表达量无明显变化(与对照组相比,P>0.05);DDP组HepG2细胞Survivin蛋白的表达量逐渐升高(与对照组相比,P<0.05),且具有时间依赖性;而中药含药血清+DDP组细胞Survivin蛋白的升高水平与DDP组相比明显降低(P<0.05)。结论益气养阴方含药血清可能通过抑制DDP诱导HepG2细胞中凋亡抑制蛋白Survivin的表达而降低HepG2细胞对化疗的抵抗,这可能是本方与化疗合用增效的重要机制之一。
