【摘要】：目的:本研究主要對山東漢族人群煙酰胺腺嘌呤二核苷酸磷酸(NADPH)氧化酶p22phox亞基CYBA基因rs9932581和rs1049255位點多態(tài)性與子癇前期(Preeclampsia,PE)遺傳易感性進行相關性分析,旨在為PE的發(fā)病機制提供新的理論依據。方法:依據PE的診斷標準,我們主要收集了來自青島大學附屬醫(yī)院、青島市婦女兒童醫(yī)院、臨沂市人民醫(yī)院、煙臺山醫(yī)院、濟寧附屬醫(yī)院、聊城市人民醫(yī)院、淄博市婦幼保健院等產科住院妊娠婦女的血清標本,其中1029例入選為PE組和1400例正常健康孕婦入選為對照組。所選取的研究對象均無嚴重的器質性疾病及產科并發(fā)癥等。常規(guī)采集PE組及對照組外周肘靜脈血2 m L(EDTA抗凝),待充分混勻后取300 ul全血分裝于1.5 m L的EP管內,保存于4℃冰箱中,48 h內進行全血基因組DNA提取,置于-20℃冰箱保存待用。應用Taqman探針實時熒光定量PCR方法,檢測CYBA基因rs9932581和rs1049255位點多態(tài)性的基因分型;采用Hardy-Weinberg遺傳平衡對對照組群體代表性進行分析;采用獨立性t檢驗或非參數檢驗進行兩組之間一般臨床資料的差異比較;采用Pearson-?2檢驗進行兩組之間基因型及等位基因頻率分布的差異比較;相對風險度用比值比和95%的可信區(qū)間來表示,當雙側P值小于0.05時表示有統(tǒng)計學意義。結果:對照組中CYBA基因rs9932581和rs1049255位點多態(tài)性的基因分布符合Hardy-Weinberg遺傳平衡檢驗(rs9932581:χ2=0.269,P=0.604;rs1049255:χ2=0.198,P=0.656),說明本實驗研究對象具有良好的群體代表性。對PE組和對照組的人口統(tǒng)計學及臨床資料進行比較,結果顯示在年齡、初潮年齡、孕次和流產次數等方面無顯著性差異(p(29)0.05);而在孕周、血壓、白細胞及中性粒細胞計數等方面具有顯著性差異(p(27)0.05)。兩組間CYBA基因rs9932581和rs1049255多態(tài)性的基因型及等位基因頻率分布均無顯著性差異(rs9932581,基因型χ2=1.444,P=0.486,等位基因χ2=0.164,P=0.686,OR=1.024,95%CI=0.913-1.148;rs1049255,基因型χ2=4.637,P=0.098,等位基因χ2=0.686,P=0.407,OR=0.952,95%CI=0.847-1.070);輕度/重度PE和早發(fā)型/晚發(fā)型PE分別與對照組進行比較,發(fā)現(xiàn)其基因型及等位基因分布亦無顯著性差異(p(29)0.05)。結論:本實驗研究結果表明,山東漢族人群CYBA基因rs9932581和rs1049255位點多態(tài)性與輕度/重度PE、早發(fā)型/晚發(fā)型PE的發(fā)生沒有相關性;山東漢族人群CYBA基因rs9932581和rs1049255位點多態(tài)性與PE的發(fā)病可能不存在關聯(lián)性。但是該基因位點多態(tài)性在其他種群中還有待進一步驗證。為了從基因的功能學及遺傳學角度對PE的發(fā)病機制進行進一步的探究,需要擴大樣本數量、收集多個地域的研究對象,并且探討不同基因在多種族人群中的作用,從而發(fā)現(xiàn)新的PE易感基因以及為該病的早期預防、早期診斷及早期治療提供新的理論基礎。
[Abstract]:Objective: to investigate the relationship between the polymorphisms of rs9932581 and rs1049255 loci in the p22phox subunit of nicotinamide adenosine dinucleotide phosphate (NADPH) oxidase and preeclampsia preeclampsis (PEP) genetic susceptibility in Shandong Han population.The aim is to provide a new theoretical basis for the pathogenesis of PE.Methods: according to the diagnostic criteria of PE, we collected mainly from affiliated hospitals of Qingdao University, Qingdao Women and Children Hospital, Linyi people's Hospital, Yantai Mountain Hospital, Jining affiliated Hospital and Liaocheng people's Hospital.The serum samples of pregnant women in maternity department such as Zibo Maternal and Child Health Hospital were collected, of which 1029 cases were selected as PE group and 1400 normal pregnant women as control group.No serious organic diseases or obstetrical complications were found in the selected subjects.The peripheral blood of PE group and control group were collected with 2 m L(EDTA anticoagulant. After fully mixing, 300ul whole blood was divided into 1.5 mL EP tube and stored in refrigerator at 4 鈩，
