Abstract： 目的探讨妊娠肝内胆汁淤积症(ICP)患者血清甘胆酸水平变化与胎盘细胞凋亡的关系,进一步分析ICP患者胎盘功能减退的可能机制.方法应用放射免疫方法,测定30例ICP患者(ICP组) 及27例正常孕妇(对照组)分娩前血清甘胆酸水平,应用免疫组化方法测定两组孕妇胎盘细胞凋亡调节基因bax和bcl-2的表达.结果 (1)ICP组甘胆酸水平为(51.8±5.9) μmol/L,对照组为(9.4±5.6) μmol/L,两组比较,差异有显著性(P<0.05).(2) ICP组胎盘合体滋养细胞bax阴性2例,弱阳性9例,中等阳性11例,强阳性8例;bcl-2弱阳性12例,中等阳性12例,强阳性6例.对照组bax阴性9例,弱阳性13例,中等阳性4例,强阳性1例;bcl-2弱阳性3例,中等阳性4例,强阳性20例.两组比较,ICP组bax表达阳性率显著高于对照组(P<0.0005), 而bcl-2的表达阳性率又显著低于对照组(P<0.0005).(3)孕妇血甘胆酸水平与胎盘bax表达阳性率呈线性正相关(P<0.005),与胎盘bcl-2表达呈线性负相关(P<0.005).结论 ICP患者血中高水平的甘胆酸使胎盘合体滋养细胞bax基因过度表达,这可能是ICP患者胎盘功能减退的机制之一.
