摘要: 目的检测肝细胞癌(HCC)患者血清胸腺素β4(Tβ4)水平及其影响因素。方法采用ELISA方法检测80例HCC患者血清Tβ4水平,并与40例健康人及30例肝硬化患者比较。同时比较不同肿瘤情况及肝功能对HCC组患者血清Tβ4浓度的影响。结果 HCC患者及肝硬化患者血清Tβ4水平均低于健康人,差异有统计学意义(χ2=81.228,P<0.001)。按照BCLC分期或CLIP分期将HCC患者分别分为4个或6个亚组,血清Tβ4浓度差异均有统计学意义(χ2=8.669~13.675,P<0.034)。HCC患者中有肝内转移组血清Tβ4浓度高于无肝内转移组,差异有统计学意义(Z=2.264,P=0.024);有门脉瘤栓组血清Tβ4浓度高于无门脉瘤栓组,差异有统计学意义(Z=2.574,P=0.010)。无肝内转移而且无远处转移的HCC患者按照肝功能Child-Pugh评分分为A、B、C级3组,血清Tβ4浓度差异有统计学意义(χ2=6.467,P=0.039)。结论肝细胞癌患者血清Tβ4浓度低于健康人,且肝功能越差,血清Tβ4浓度越低。而发生肝内转移或门脉瘤栓的患者血清Tβ4浓度高于未发...Abstract: Objective To investigate serum thymosin β4 (Tβ4) level in patients with hepatocellular carcinoma (HCC) .Methods Serum Tβ4 level were measured in 80 patients with HCC, 40 patients with cirrhosis and 40 healthy controls.Serum Tβ4 level were measured by enzyme-linked immunosorbent assay (ELISA) .Level of serum Tβ4 in different stages of HCC were compared.Patients with HCC were divided into groups according with or without interhepatic metastasis, portal vein tumor thrombus and distant metastasis and then compared.Results Compared with that in healthy controls, serum Tβ4 level in patients with HCC and cirrhosis was lower with statistically significant difference (χ2=81.228, P<0.001) .Patients with HCC had divided into group A, B, C and D according their BCLC stage.Level of Tβ4 in these 4 groups was statistically significant difference (χ2=8.669, P=0.034) .Patients with HCC were divided into group 0, 1, 2, 3, 4 and 5 according CLIP score.Level of Tβ4 in these 6 groups had statistically significant difference (χ2=13.675, P=0.018) .Meanwhile, Patients with HCC were also divided according interhepatic metastasis, portal vein tumor thrombus and distant metastasis.Serum Tβ4 level was higher in patients with interhepatic metastasis than that in those without metastasis (Z=2.264, P=0.024) .Serum Tβ4 level was higher in patients with portal vein tumor thrombus than that in those without tumor thrombus (Z=2.574, P=0.010) .Patients who developed neither portal vein tumor thrombus nor distant metastasis were divided into group A, B and C according Child-pugh grade and there was statistically significant difference (χ2=6.467, P=0.039) .Conclusion Serum Tβ4 level in patients with HCC were lower than that in healthy controls.And serum Tβ4 level in patients with interhepatic metastasis or portal vein tumor thrombus was higher than that in patients without those diseases.
