摘要:
目的检测肝细胞肝癌患者血浆中甘露糖结合凝集素(MBL)、MBL相关丝氨酸蛋白酶-2(MASP-2)的表达水平,探讨其与 肝细胞肝癌发生发展的相关性。方法用酶联免疫吸附测定方法检测64 例肝细胞肝癌患者及30 例健康人血浆中MBL及 MASP-2的表达水平,并用统计学方法分析患者血浆中MBL及MASP-2的浓度与各临床指标的相关性。结果肝细胞肝癌患 者血浆中MBL和MASP-2的浓度均显著高于健康人群(P=0.014、0.002),MBL/MASP-2比值在健康人群与肝细胞肝癌患者中 的差异无统计学意义,此外,患者血浆中MBL与MASP-2并无相关性。在肝细胞肝癌患者中,血浆MBL水平与肿瘤的血管侵 犯(r=0.253,P=0.047)和总胆红素水平(r=0.283,P=0.024)呈正相关;血浆中MASP-2水平与肝细胞肝癌的TNM分期呈正相关 (r=0.276,P=0.027),而与血浆白蛋白呈负相关(r=0.-0.317,P=0.015)。经ROC曲线分析,MBL和MASP-2曲线下面积分别为 0.665(P=0.010)和0.694(P=0.003),对肝细胞肝癌诊断的敏感性分别为50%和89.1%。结论补体凝集素途径的关键分子 MBL、MASP-2 与肝细胞肝癌患者的炎症状态和疾病进展相关,参与了肝癌的发生与发展。
Abstract:
Objective To detect the plasma levels of mannan-binding lectin (MBL) and MBL-associated serine protease-2 (MASP- 2) in patients with hepatocellular carcinoma (HCC) and explore their role in the tumorigenesis and progression of HCC. Methods The plasma levels of MBL and MASP-2 were detected by enzyme-linked immunosorbent assay in 64 HCC patients and 30 healthy control subjects. The correlation of MBL and MASP-2 with the clinical parameters of HCC patients were analyzed. Results The plasma levels of MBL (P=0.014) and MASP-2 (P=0.002) were significantly higher in HCC patients than in the healthy controls, but the MBL-to-MASP-2 ratio did not differ significantly between the two groups. In HCC patients, plasma MBL level was positively correlated with vascular invasion (r=0.253, P=0.047) and total bilirubin level (r=0.283, P=0.024). The plasma level of MASP-2 was positively correlated with TNM stage (r=0.276, P=0.027) and negatively correlated with plasma albumin level (r=0.-0.317, P=0.015). ROC curve analysis revealed an area under curve of 0.665 for MBL (P=0.010) and 0.694 for MASP-2 (P=0.003). The sensitivities of MBL and MASP-2 were 50% and 89.1% in the diagnosis of HCC, respectively. Conclusion MBL and MASP-2 are associated with the inflammatory state and disease progression in patients with HCC.
