中文摘要:
      目的 探讨循环miRNA-4281在肝癌患者血清中的表达情况及对诊断的临床意义。方法运用QRT-PCR技术分别检测45例肝癌患者(肝癌组)及正常人(对照组)血清中miRNA-4281的表达量。结果与对照组相比,肝癌患者血清标本中miRNA-4281的表达量明显高于正常人,且差异有统计学意义(P<0.05)。ROC曲线下面积是0.805,microRNA-4281作为肝癌诊断的灵敏度为84.40%,特异度是73.30%。miRNA-4281的表达与AFP无明显相关性。Kaplan-Meier分析提示miRNA-4281表达水平高的患者具有较短的生存期限(P<0.05)。结论检测miRNA-4281有利于肝癌的诊断,可作为HCC 潜在的临床诊断标志物,同时其对于评估患者的预后具有重要作用。
英文摘要:
      Objective To measure the expression of the circulating miRNA-4281 in the serum of patients with hepatocellular carcinoma (HCC),and to find out the clinical meaning in diagnosis.MethodsBlood samples from normal healthy (n=45) and HCC patients (n=45) were collected,respectively.Quantitative Real-time PCR was used to detect the expression level of miRNA-4281 in the two groups.ResultsThe expression of miRNA-4281 was significantly higher in the patients compared to that in the control (P<0.05).The area under receiver-operating characteristic curve was 0.805,with the sensitivities of 84.40% and the specificities of 73.30%.The expression level of miRNA-4281 and AFP had no correlation.Kaplan-Meier showed that the patients seemed to live a shorter time with the high expression of miRNA-4281(P<0.05).ConclusionDetecting miRNA-4281 may help to diagnose HCC.MiRNA-4281 may be a potential marker in the diagnosis and the prognosis.
