hepatocellular 癌(HCC ) 的 carcinogenesis 是的背景一多因素, multistep 和复杂过程。它的预后是差的,早察觉具有最大的重要性。转变生长因素 1 (TGF-1 ) 消息 RNA (mRNA ) 被报导了用北弄污在 HCC 病人被提高。然而,工作关于 TGF-1 mRNA 的察觉被做了的很少用即时聚合酶链反应(PCR ) 与 HCC 在病人的外部血铺平方法。目的将与 HCC 在病人的外部血估计 TGF-1 mRNA 的量的层次的预示的价值,并且在外部血和许多诊断、病理学的因素调查在 TGF-1 mRNA 的表示之间的关系。我们开发了优化 Taqman 即时 PCR 确定的方法在有 HCC 和 44 个健康志愿者的 53 个病人的外部血的 TGF-1 mRNA。另外,血为测量全部的 bilirubin ( TBil )的层次与 HCC 从病人被收集, prealbumin ,白朊,丙氨酸 aminotransferase (中高音), aspartate aminotransferase (著名计算机生产厂商), gamma glutamyltranspeptidase ( GGT ), alpha-L-fucosidase ( AFU ), alpha fetoprotein (法新社),carcino胚胎的抗原( CEA ),糖类抗原 19-9 ( CA19-9 ),病毒的负担和血小板数。统计分析用 SPSS 软件系统(社会科学统计套装软体 10.0 ) 被执行。在即时 PCR 的结果,荧光在从有 HCC 和健康志愿者的病人的所有血标本是可检测的。在有 HCC 的病人的 TGF-1 mRNA 表示的层次在健康志愿者与那相比是显著地更高的(P < 0.000 1 ) ,与 hepatocarcinogenesis 建议激活的 TGF-1 基因抄写的一个协会。有 HCC 的病人根据他们上面的 TGF-1 mRNA 被划分成 2 个组(组 A, n=28 ) 或在下面(组 B, n=25 ) 吝啬的水平。统计结果证明那 TGF-1 mRNA 表示水平与病人年龄, CEA 的浆液层次, CA19-9 和病毒的拷贝数字被相关(P < 0.05 ) 。结论尽管这是一件小样品,缩放预研项目这些调查结果在外部血暗示 TGF-1 mRNA 水平的那量的大小可以是 HCC 的一个互补 serologic 标记。
Background: The carcinogenesis of hepatocellular carcinoma (HCC) is a multi-factorial, multistep and complex process. Its prognosis is poor and early detection is of the utmost importance. Transforming growth factor β1 (TGF-β1) message RNA (mRNA) has been reported to be elevated in HCC patients using Northern blotting. However, little work has been done about the detection of TGF-β1 mRNA levels in peripheral blood of patients with HCC using the real-time polymerase chain reactions (PCR) method. Objective: To assess the prognostic value of quantitative levels of TGF-β1 mRNA in peripheral blood of patients with HCC, and to investigate the relationship between the expression of TGF-β1 mRNA in peripheral blood and many diagnostic and pathological factors. Methods: We developed an optimized Taqman real-time PCR to quantify TGF-β1 mRNA in peripheral blood of 53 patients with HCC and 44 healthy volunteers. In addition, blood was collected from patients with HCC for measuring levels of total bilirubin (TBil), prealbumin, albumin alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma glutamyltranspeptidase (GGT), alpha-L-fucosidase (AFU), alpha fetoprotein (AFP), carcino-embryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), viral load and platelet counts. Statistical analysis was performed using the SPSS software system (SPSS 10.0). Results: In real-time PCR, fluorescence was detectable in all blood specimens from patients with HCC and healthy volunteers. The levels of TGF-β1 mRNA expression in patients with HCC were significantly higher compared to that in healthy volunteers (P〈0.000 1), suggesting an association of the activated TGF-β1 gene transcription with hepato- carcinogenesis. Patients with HCC were divided into 2 groups according to their TGF-β1 mRNA above (group A, n=28) or below (group B, n=25) the mean level. Statistical results demonstrated that TGF-β1 mRNA expression level was correlated with patients
