1、重庆医科大学硕士学位论文TLR4和IL--18在妊娠期肝内胆汁淤积症孕妇胎盘组织中的表达及其意义姓名:邓力哲申请学位级别:硕士专业:妇产科学指导教师:邵勇201205重庆医科大学硕士研究生学位论文TLR4和IL-18在妊娠期肝内胆汁淤积症孕妇胎盘组织中的表达及其意义摘要目的探讨TOLL样受体4(TLR4)和白介素-18(IL-18)在妊娠期肝内胆汁淤积症(ICP)孕妇胎盘中的表达及意义。方法收集2011年5月一2011年lO月在重庆医科大学附属第一医院分娩的ICP孕妇胎盘绒毛组织,其中正常孕妇10例(对照组),ICP轻度
2、孕妇10例(ICP轻度组),ICP重度孕妇10例(ICP重度组)。免疫组化检测胎盘组织中TLR4和IL-18的定位表达,Westernblot检测TLR4和IL-18的表达水平。结果(1)TLR4定位表达在研究组和对照组的胎盘合体滋养细胞的细胞质膜;IL-18定位表达在研究组和对照组的胎盘合体滋养细胞的细胞质内。(23Westernblot结果显示:对照组、ICP轻度组及ICP重度组孕妇胎盘组织中TLR4和IL-18蛋白的表达水平分别为TLR4:(0.33±0.04)、(0.74±0.03)及(1.07±0.01),IL
