Abstract 【目的】 观察不同序贯的西妥昔单抗(cetuximab)与化疗药物联合对人肝癌细胞系HepG2和Bel-7402的增殖抑制作用,并分析其意义? 【方法】 浓度递增的cetuximab和表柔比星?奥沙利铂?泰素?伊立替康四种化疗药物分别按照不同给药序贯联合作用于HepG2和Bel-7402细胞,使用细胞计数试剂盒CCK-8检测不同给药序贯的药物对HepG2和Bel-7402细胞的增殖抑制作用,利用生物学软件Calcusyn计算不同给药序贯时cetuximab和化疗药物的半数抑制浓度(IC50)的变化,计算其作用的协同系数(CI)? 【结果】 Cetuximab和化疗药物联用对HepG2和Bel-7402细胞的增殖抑制作用受给药序贯影响:cetuximab先于化疗药物给药,两者的IC50较单用时降低,但是CI值均大于1,两者之间为拮抗效应;cetuximab后于化疗药物给药,两者的IC50较单用时降低更为明显,且CI值均小于1,两者之间具有较明显的协同效应? 【结论】 Cetuximab与化疗药物联用对肝癌细胞的增殖具有协同抑制作用,较佳的给药序贯是化疗药物先于cetuximab给药,能获得明显的协同效应,这有助于临床用药时降低药物剂量,减少毒副作用?
