目的:探讨尿液硫酸化胆汁酸代谢轮廓分析在识别无症状高胆汁酸血症(asymptomatic hypercholanaemia of pregnancy,AHP)中的应用价值。方法:应用高效液相色谱-串联质谱法(HPLC-MS/MS)测定正常孕妇(13例),妊娠肝内胆汁淤积症(intrahepatic cholestasis of pregnancy,ICP)(17例)尿液硫酸化胆汁酸谱,采用不同扫描模式鉴别和分析尿液各种硫酸化胆汁酸,并用主成分分析法(principle component analysis,PCA)对尿液硫酸化胆汁酸代谢轮廓进行分析。结果:采用不同的扫描模式对尿液中15种可能的硫酸化胆汁酸进行鉴定并分析,经PCA对尿液硫酸化胆汁酸代谢轮廓分析,发现在ICP组中存在一类特殊的人群,其表现为无任何症状的胆汁酸水平升高而肝功能正常,但其尿液硫酸化胆汁酸代谢轮廓与正常孕妇类似。结论:尿液硫酸化胆汁酸代谢轮廓分析有助于AHP的识别。
【英文摘要】
Objective:To investigate the feasibility of metabolic profiling of urinary sulfated bile acid in intrahepatic cholestasis of pregnancy(ICP) identification. Methods:High performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS) was employed to determinate urinary sulfated bile acids in 13 healthy pregnant women and 17 patients with ICP. Multiple scanning modes were used to identify and analyze possible sulfated bile acids in urine. Datas were analyzed by principle component analysis(PCA).Results...
