摘要：

目的:在中医药理论指导下,深入研究中医药抗恶性肿瘤单一信号通路及多靶点联合治疗的机制。方法:中药组与对照组分别以低(3.78g/kg)、中(7.56g/kg)、高(15.12g/kg)剂量消癌解毒方中药及0.9%氯化钠溶液灌胃3d,制备含药血清,经细胞培养,透射电镜观察肿瘤细胞凋亡及坏死微观结构,Western Blot法检测消癌解毒方及在此基础上加入激动剂脂多糖(LPS)及TLR4阻断剂(CD284)对人肝癌细胞SMMC-7721的TLRs/NF-κB信号转导通路的影响。结果:高浓度含药血清加入CD284剂量组电镜下可见人肝癌细胞株SMMC-7721变性,水肿,胞质细胞器广泛空泡变,部分细胞碎裂,坏死,胞核溶解,胞膜破裂,细胞器外溢;Western Blot法检测TLR4等mRNA和蛋白表达水平最弱。结论:消癌解毒方能够明显抑制人肝癌细胞SMMC-7721的增殖,其机制可能是含药血清与CD284能协同作用于人肝癌细胞SMMC-7721的TLRs/NF-κB信号转导通路,抑制核转录因子NF-κB的异常持续活化,促进肿瘤细胞凋亡。
