【摘要】:目的:研究妊娠期肝内胆汁淤积症(intrahepatic cholestasis ofpregnancy,ICP)孕妇胎盘合体滋养细胞中组蛋白去乙酰化酶3(histone deacetylase3, HDAC3)的定位和表达,探讨其表达变化与ICP病理生理过程的关系。 方法:选择重庆医科大学附属第一医院2012年3月至2013年11月分娩的ICP孕妇30例为研究对象,其中包括轻度组(15例),重度组(15例),选择同一时期在该医院行择期剖宫产术的无妊娠合并症的孕妇15例为正常对照组。采用ELISA法测血清中TNF-α水平,免疫组化及westernblot检测胎盘合体滋养细胞HDAC3的表达,同时测血清中TBA及ALT、AST水平。 结果:(1)ICP重度组、ICP轻度组、对照组血清TNF-α水平分别为:(52.35±3.16) ng/L、(39.08±2.27) ng/L、(32.40±2.13) ng/L;ICP重度组、ICP轻度组、对照组血清TBA水平分别为:(69.95±21.47)ng/L、(11.31±0.76)ng/L、(2.70±0.21)ng/L;ICP重度组、ICP轻度组、对照组血清ALT水平分别为:(312.2±34.7)U/L、(101.7±19.2)U/L、(21.9±2.8)U/L;ICP重度组、ICP轻度组、对照组血清AST水平分别为:(237.7±31.6)U/L、(71.0±12.9)U/L、(17.3±1.3)U/L;在ICP重度组孕妇血清中,TNF-α、TBA、AST和ALT水平较ICP轻度组和正常对照组有明显的升高,分别比较,,组间差异有统计学意义(P0.05);血清中TBA及AST、ALT水平在ICP轻度组孕妇明显高于正常对照组,差异有统计学意义(P0.05)。ICP轻度组孕妇血清中,TNF-α水平与正常对照组孕妇血清中TNF-α水平进行比较,差异无统计学意义(P>0.05)。(2)在ICP重度组及轻度组HDAC3定位在胎盘合体滋养细胞胞核,着色较淡,呈淡棕黄色染色;在正常对照组,HDAC3也在胎盘合体滋养细胞表达,主要在胞核着色,但呈棕黄色浓染。(3)ICP重度组和轻度组胎盘合体滋养细胞中HDAC3表达水平分别为:(0.077±0.006)及(0.076±0.007),两组比较差异无统计学意义(P>0.05),两组明显低于对照组的(0.232±0.018),分别比较差异均有统计学意义(P<0.01)。(4)胎盘合体滋养细胞中HDAC3的定量表达与血清中TNF-α、TBA及ALT、AST水平呈负相关,Spearman相关系数分别为-0.340,-0.688,-0.533,-0.577。 结论:(1)ICP孕妇胎盘合体滋养细胞中HDAC3表达下调。(2)ICP孕妇胎盘合体滋养细胞中HDAC3的定量表达与血清中TNF-α、TBA及ALT、AST水平呈负相关。(3)ICP孕妇胎盘合体滋养细胞中HDAC3表达下调介导的免疫损伤可能与ICP孕妇肝功能异常有关。
[Abstract]:Objective: To investigate the localization and expression of histone deacetylase 3 (histone deacetylase3, HDAC3) in placental syncytial trophoblast cells of pregnant women with intrahepatic cholestasis ofpregnancy (ICP), and to explore the relationship between the expression change and ICP pathophysiology.
Methods: pregnant women with ICP in First Affiliated Hospital of Chongqing Medical University from March 2012 to November 2013 30 cases of delivery as the research object, including mild group (15 cases), severe group (15 cases), select the same period in the hospital without complications of pregnancy undergoing elective cesarean section of 15 cases of pregnant women as normal control group. TNF- alpha the level of serum by ELISA method, the expression of Westernblot and immunohistochemical detection of HDAC3 in syncytiotrophoblast were measured at the same time, TBA and ALT, the level of AST in serum.
