摘要 目的:研究金复康口服液对非小细胞人肺腺癌吉非替尼获得性耐药的影响。方法:应用血清药理学的方法,选择人肺腺癌PC-9细胞及人肺腺癌获得性耐吉非替尼PC-9R细胞株,MTT法检测细胞增殖率,计算IC50、逆转耐药倍数、协同效应;west-blot法、Real-time PCR检测P-EGFR的表达。结果:金复康口服液含药血清、金复康口服液含药血清联合吉非替尼对PC-9、PC-9R细胞的增殖抑制作用呈时效及量效关系;金复康口服液含药血清逆转吉非替尼的耐药倍数为11.3倍,Q值为2.32,大于1.15,表明两药有协同作用;金复康口服液含药血清联合吉非替尼组P-EGFR及P-EGFR mRNA的表达显著低于吉非替尼组(P<0.05)。结论:金复康口服液能逆转吉非替尼的获得性耐药,其机制可能与下调P-EGFR表达有关。
