摘 要:目的 检测中药肝复健冲剂对DEN诱导大鼠肝癌过程中细胞周期相关因子的影响. 方法 建立DEN诱肝癌模型的同时预防性应用肝复健冲剂,采用免疫组化染色方法及计算机图像分析技术检测肝复健冲剂对DEN诱癌不同时期大鼠肝细胞CDK4,cyclinD1及p27阳性表达的影响. 结果 DEN诱癌过程中CDK4,cyclinD1呈逐渐增加趋势,p27变化不明显,三者相关性无显著意义.肝复健冲剂可明显降低DEN诱癌不同时段CDK4的阳性表达[(86±3)~(101±6),(4wk);(67±3)~(92±5),(8wk);(94±6)~(116±7),(12wk);(102±4)~(119±2),(16wk);(97±4)~(119±4),(20wk)],显著降低诱癌后期肝细胞cyclinD1的阳性表达(84±2)~(116±12),(P<0.05).对p27表达变化影响无显著意义. 结论 肝复健冲剂对DEN诱导大鼠肝癌的预防作用可能与其降低细胞周期正性调节因子CDK4,cyclinD1等的表达有关.
