摘要 [目的]探讨胆道引流对恶性肿瘤梗阻性黄疸病人肝细胞凋亡的影响。[方法]用末端脱氧核苷酸转移酶介导生物素标记(TUNEL)技术和免疫组织化学方法检测34例胰头癌、胆管癌恶性阻塞性黄疸病人胆道引流后肝细胞增殖、凋亡状态及凋亡相关基因bcl-2和bax蛋白的表达。[结果]胆道引流后,bax蛋白表达减弱(27.34%±8.26%vs.7.24%±2.45%),差异有显著性(P<0.01);bcl-2蛋白表达增强(9.25%±3.23%vs.24.53%±7.64%),差异有显著性(P<0.01);凋亡指数(AI)迅速下降(53.67%±15.26%vs.7.57%±3.26%),差异有显著性(P<0.01)。[结论]早期引流有利于改善肝功能、降低肝细胞凋亡率,bcl-2和bax蛋白均参与了阻塞性黄疸肝细胞凋亡的调节。
