摘  要:目的 探讨血清去γ-羧基凝血酶原(DCP)、高尔基体蛋白73(GP73)、热反应蛋白70(HSP70)水平对肝癌的诊断价值.方法 收集2013年1至7月桂林医学院附属医院肝癌患者35例、健康对照者35名.采用电化学发光法和酶联免疫吸附法定量检测各组血清DCP、GP73、HSP70和甲胎蛋白(A FP)水平.结果 健康对照组AFP、DCP、GP73水平分别为1.240(0.605 ~ 5.310) μg/L、104.606(0.000 ~4 138.770)pg/ml、30.770(16.343 ~ 87.453) ng/ml,肝癌组分别为13.780(1.140 ~8 487.000)μg/L、3 213.953(2.510 ~53 994.602) pg/ml、76.838(24.500 ~ 232.875) ng/ml,均明显高于健康对照组,差异有统计学意义(U=134.50、258.00、168.00,均P<0.01);2组血清均未能检测出HSP70.血清DCP、GP73用于肝癌诊断的ROC曲线下面积分别为0.789、0.863,以2 939.4 pg/ml、41.3 ng/ml作为DCP、GP73诊断肝癌的临界值,则DCP诊断肝癌的敏感度为54.3%,特异度为97.1%,GP73诊断肝癌的敏感度为85.7%,特异度为74.3%.本研究中以常规20 μg/L作为血清AFP诊断的临界值,其敏感度仅为45.7%,特异度为100%,准确度为72.9%.联合检测中,GP73/AFP诊断肝癌的敏感度为88.6%,特异度为74.3%,准确度为81.4%;GP73/DCP/AFP诊断肝癌的敏感度为91.4%,特异度为71.4%,准确度为81.4%.结论 GP73联合AFP或GP73、DCP联合AFP检测可提高肝癌早期诊断的敏感度及准确度,建议将GP73、DCP及AFP的联合检测应用于肝癌的早期血清学诊断.Objective To analyze the clinical value of the detection of serum desgamma carboxy prothrombin (DCP),golgi glycoprotein 73 (GP73),heat-shock protein 70 (HSP70) in primary hepatic carcinoma (PHC) diagnosis.Methods Enzyme-1inked immunosorbent assay and electrochemiluminescence immunoassay were used to detect the serum DCP,GP73,HSP70 and α-fetoprotein (AFP) levels in 35 PHC patients and 35 healthy controls.Results AFP,DCP and GP73 levels in PHC patients were 13.780(1.140-8 487.000) μg/L,3 213.953 (2.510-53 994.602) pg/ml and 76.838 (24.500-232.875) ng/ml respectively,significantly higher than those in healthy controls (1.240 (0.605-5.310) μg/L,104.610 (0.000-4 138.770) pg/ml and 30.770(16.343-87.453) ng/ml,U value were 134.50,258.00 and 168.00,all P <0.01) ; HSP70 could not be detected in any objects.The area under the ROC curve of DCP or GP73 was 0.789,0.863 respectively.The sensitivity and specificity to PHC diagnosis were 54.3% and 97.1% by DCP (2 939.4 pg/ml as cut-off value),85.7% and 74.3% by GP73 (41.3 ng/ml as cut-off value),45.7% and 100% by AFP (20 μg/L as cut-off value).In combined detection the sensitivity,specificity and accuracy were 88.6%,74.3%,81.4% by GP73/AFP and 91.4%,71.4%,81.4% by GP73/DCP/AFP.Conclusion GP73,DCP are new effective markers in the diagnosis of PHC,and the combined detection of GP73,DCP and AFP can improve the diagnosis value of PHC.
