[摘要]目的 探索胰岛素和C肽浓度的变化评估肝脏功能的可行性.方法 同步抽取82例临床肝癌患者门静脉和外周血液,检测其胰岛素和C肽浓度,统计学分析门静脉和外周血液中胰岛素和C肽差异.结果 分析显示胰岛素在门静脉和外周血液浓度均值分别为32.43 μU/mL和8.05 μU/mL,存在差异有统计学意义(P<0.05),C肽在门静脉和外周血液浓度均值分别为1.38 μU/mL和1.19 μU/mL,差异无统计学意义(P>0.05).结论 肝脏作为胰岛素的靶器官对胰岛素的代谢作用很大,C肽不参与体内代谢,因此通过对比分析胰岛素和C肽的代谢率的变化来评估肝脏功能是可行的. |

[Abstract]Objective To analyze the concentration changes of insulin and c peptide of in portal vein and peripheral blood, and explore the feasibility of using insulin and c peptide concentration changes in assessment of liver function. Methods The portal vein and peripheral blood samples were extracted from 82 clinical liver cancer patients,and the insulin and c peptide concentration were detected. The differences in the insulin and c peptide concentration in portal vein and peripheral blood were statistically analyzed. Results The insulin concentration in the portal vein and peripheral blood values were 32.43 μ U/ml and 8.05 μ U/ml, respectively, there was a significant difference(P<0.05). The c-peptide concentration in the portal vein and peripheral blood values were 1.38 μU/mL and 1.19 μg U/mL, respectively, there was no significant differences(P>0.05). Conclusion Liver metabolizes insulin as the target organ of insulin, while c-peptide dose not be metabolized in vivo, so it is possible to assess liver function by comparative analysis of the metabolic rate of insulin and c-peptide changes. |
