1、兰州医学院硕士学位论文肝细胞生长因子与妊娠高血压综合征发病的关系姓名:吴海霞申请学位级别:硕士专业:妇产科指导教师:王秀华2002.5.1肝细胞生长因子与妊娠高血压综合征发病的关系研究生吴海霞导师王秀华兰州医学院第一附属医院妇产科甘肃’兰州730000摘要【目的】观察肝细胞生长因子(HGF)mRNA在妊娠高血压综合征胎盘组织中的表达,探讨妊高征的发病机制。【方法】本试验采用逆转录一聚合酶链式反应(RT-PCR),选择20例重度妊高征患者及20例正常足月妊娠妇女为对照,胎盘娩出后,立即于胎盘母体面中央避开缺血、坏死及钙化区,取
2、大小约1.0X1.0×0.5cm3的胎盘组织。抽提细胞总RNA,利用HGF的一对特异性引物对总RNA进行逆转录和扩增。采用凝胶成像系统分析}lGFIRNA的扩增条带,检测HGFmRNA的表达水平。【结果】1.PCR扩增产物经琼脂糖凝胶电泳后,在248bD处可见一1条HGF的扩增带。2.妊高征患者胎盘组织中HGFmRNA的表达峰度为0.19±0.07(;±s),正常妊娠组胎盘组织中HGFraRNA的表达峰度值为0.33+0.05(;±s),妊高征组胎盘组织中HGFmRNA的表达水平显著降低(P3、组织中有HGFmRNA的表达。2.妊高征患者HGF表达异常发生于转录水平,HGF的异常表达在妊高征胎盘缺氧中有重要作用。【关键词】妊娠高血压综合征肝细胞生长因子胎盘逆转录一聚合酶链式反应Relationbetweenhepatocytegrowthfactorandthepathogenesisofpregnancy-inducedhypertensionPostgraduate:WuHaixiaTutor:WangXiuhuaDepartmentofObstetricsandGynecology,theFirstTeach4、ingHospitalLanzhouMedicalCollegeLanzhou,Gansu,73000Abstract[Objective]Theexpressionofhepatocytegrowthfactor(HGF)mRNAinpregnancyinducedhypertension(PIH)wasobservedandthepathogenesisofPIHwasstudied.[Method]Thereversetranscriptional-polymerasechainreaction(RT-PCR)wasu5、sed.20patientsand20normotensivetermpregnanciesvoluteeredforourstudy.1.0×1.0X0.5centimetertissueofmaternalplacentaclosedtothecenterwascollected.ThetotalRNAwasfirstisolatedfromtheplacentaltissues,thenone—stepRT—PCRwasundertakenwith3thespecialHGFprimer.Thephotosystemw6、asusedtoascertainlevelofexpressionofHGF[Result]1.OnezoneforHGFonagarwasobserved。whichnear248bp2.ThelevelofHGFinPIHis0.19±0.07(;±j),andnormotensivecontrolis0.33±O.05(;±s).ThetranscriptionofHGFmRNAinplacentafromPIHdecreasedsignificantly(P7、isexpressedinhumanplacenta.2.TheabnormalexpressionofHGFinPIHoccurredwithinIow—streamofgenictranscription.ItmaybeconsideredthatabnormalexpressionofHGFmayplayanimportantroleinpathogenesisofplacentalischemiainPIH.[KeyWords]PregnancyinducedhypertensionHepatocytegrowthf8、actorPlacentaReversetranscriptional—polymerasechainreaction(RT-PCR)4前言妊娠高血压综合征是孕产妇死亡的主要原因之一,其围产期死亡率也显著增加,PIH的发病率约为4~5%。其病因尚未被完全阐明,学说很多,主要学说有:子宫一胎
