摘　　要：目的 :为观察肝癌患者癌组织与外周血Th1 Th2细胞变化及临床意义。方法 :Th1 Th2细胞检测采用酶联免疫斑点法 (ELISPOT) ,细胞因子检测采用双抗体夹心ELISA法。结果 :肝癌患者癌组织与外周血Th1 Th2细胞比值明显降低 (P <0 0 5 ) ,其Th1型细胞表达IL 2、INF γ等细胞因子水平明显低于正常对照组 ;Th2型细胞表达IL 4、IL 10等细胞因子水平明显高于正常对照组。PHA和IL 12介导肝癌患者手术切除前和手术切除 3个月后外周血Th1型细胞表达IL 2、INF γ等细胞因子水平升高 ,Th2型细胞表达IL 4、IL 10等细胞因子水平明显下降。结论 :肝癌患者癌组织与外周血Th1 Th2细胞比值均明显降低 ,细胞因子表达失衡 ,肝癌患者存在免疫功能抑制 ,因此 ,在肝癌治疗过程中打破免疫抑制 ,纠正Th1Objective:To investigate the changes of Th1/Th2 ratio in the PBMC and hepatocellular carcinoma tissues of patients with heptocellular carcinoma and its clinical significance.Methods:Th1/Th2 subsets and cellular factor were detected by ELISPOT and double-sandwich ELISA.Results:Th1/Th2 ratio in the PBMC and hepatocellular carcinoma tissues of patients with heptocellular carcinoma,Th1 sebset expressing cellular factor IFN-γ,IL-2,IL-12 were significantly lower,and Th2 sebset expressing cellular factor IL-4,IL-10 were significantly higher than those of the normal control group.PMBC in patients with heptocellular carcinoma producing Th1 sebset cytokins deduced by PHA and IL-12 were significantly higher and producing Th2 sebset cytokins were significantly lower than those in the three month after operation.Conclusion:Th1/Th2 ratio in the PBMC and hepatocellular carcinoma tissues were of imbalance and immune functional status of patients with hepatocellular carcinoma was inhibitory.Therefore,it was nessassory to enhance immune functional status of patients during treatment.
