1、青岛人学坝{j学位论文摘要目的:1、了解淄博妊娠期妇女血ttCMV感染现状和探讨利用荧光定量核酸扩增法检测羊水标本对孕期宫内病毒感染的诊断价值。2、探讨孕中期血Free-0-HCG水平与HCMV宫内感染的相关性及其可能影响机制。材料和方法:收集淄博市妇幼保健院产科门诊就诊孕中期产前筛查(妊娠18—20周)的孕妇1873例,年龄21-37岁,经B超确诊均为单胎妊娠。以酶联免疫吸附法(ELISA)测孕妇血浆HCMV—IgM和荧光定量PCR法检测孕中期妇女血清以及羊水细胞培养前后HCMV~DNA浓度;通过DILFIA法(时间分辨免疫荧光法)定量检测孕中期妊娠妇女血清Free—S—HCG的含量,并进
2、行统计学处理。结果:1、孕妇巨细胞病毒感染率为2.51%(ELISA),3.36%(荧光定量PCR)。孕妇血清HCMV-IgM抗体和HCMV-DNA两项指标检测均阳性,对宫内感染的诊断价值比单项检测阳性高(P<0.05)。2、孕中期HCMV宫内感染组比非感染组外周血Free—D—hog的测定水平降低,两者结果之间的差异具有统计学意义(P3、血Free—B—hcG的测定水平降低,两者结果之间的差异具有统计学意义,分析HCMV可通过损伤胎盘绒毛滋养层细胞,使Free—p—hcG的分泌减少。硕士研究生张立群(病原生物学)指导教师王斌教授关键词:人巨细胞病毒IgM:HCMV—DNA:宫内感染:血F一13一HCG;摘复ABSTRACTObjectives:1.ToInvestigatetheinfectionofpregnantwomeninZibocityandexploretheHCMVassayforthedetectionofamnioticfluidsampleswereamplifiedindiagnosisofpregna4、ncyuterineendotoxininfectionbyfluorescentquantitativenucleicacid.2.Exploringthecorrelationbetweensecond-trimesterbloodFree—B—HCGlevelsandthetICMVintrauterineinfectionanditspossiblemechanism.Methods:Collectionof1873pregnantwomen,age21-37yearsoldofsecondtrimesterprenatalscreening(18—20weeksofpregnanc5、y)inZiboMaternalandChildHealthHospitalobstetricsoutpatients,whosediagnosisweresingletonpregnancybytheBultrasound.WiththemethodofELISAtestpregnantmaternalplasmaHCMVolgMandfluorescencequantitativePCRaroundthemiddleconcentrationofHCMV-DNAwomen’Splasmaandamnioticfluidcellculture;ThroughtheDILFIAmethod(6、TRFIA)quantitativedetectionofsecondtrimesterpregnancyinwomenserumFree-D—HCG,andcarriesonstatisticsprocessing.Result:1.HCMVinfectioninpregnantwomenwas2.51%(ELISA),3.36%(fluorescencequantitativePCR).DetectionofthetwoindicatorsofmaternalserumHCMV-IgMantibodyandHCMV-DNAwerepositive,indiagnosisofintraut7、erineinfectionthansinglepositivehigh(P<0.05)2.ThelevelofperipheralbloodFree—p—hcG,decreasesinSecondtrimesterintrauterineHCMVinfectiongroupthanininfectedgroup.Differencesbetweenthetworesultshavestatisticalsi
