1、2009年第13卷第12期实用临床医药杂志JournalofClinicalMedicineinPractice·1·PAI一1基因多态性对哮喘气道重塑影响的研究张晓岩,林江涛,杨萌,何洁,黄小杰,蔡哲,张岚,舒峻(1.卫生部中日友好医院呼吸内科,北京,100029;2.卫生部中日友好医院临床医学研究所免疫室,北京,100029)摘要:目的探讨纤溶酶原激活物抑制剂一1(PAI一1)基因启动子一6754G/5G多态性对哮喘气道重塑的影响。方法慢性持续期哮喘患者(30例)和健康人(20名)分列为轻度哮喘组、中重度哮喘组和健康人组,用等位摹
2、因特异性PCR(AS())法测定PAI一1启动子区域一675位点多态性,ELISA法测定血浆PAI一1、TGF-13l和MMP一9水平,高分辨率CT(}{】CT)观察所有受试者肺部影像学特征,运用PickerpQ6Oo0分析软件测定气道壁厚度(T)、气道壁面积(wA),采用气道壁厚度/气道外径(T/D)和气道壁面积占气道总面积百分比(wA%)作为标化指标。结果PAI一1的4G/4G、4G/5G和5G/5G3种基因型表达的TGF-~31、T和WA%差异有统计学意义(P3、335,P<0.05),与T、T/D、WA和WA%元相关关系(P>O.05)。多元方差分析娃示PAI一1基因多态性、血浆TGF一融、血浆PAI一1水平与PAI~14G/5G基因多态性的交互作用对气道重塑表型的影响有统‘学意义(P=0.050,P=0.026,P=0.030)。结论PAl一1启动子4G/5(多态性可能是哮喘气道重魍的独立影响因素。关键词:纤溶酶原激活物抑制剂一1;基因多态性;气道重塑;高分辨率CT中图分类号:R562.2文献标识码:A文章编号:1672—2353(2009)l2-0001-06Roleof4G/5Gpol4、ymorphismofPAI一1geneinairwayremodelingZHANGXiao-yan,LINJiang-tao,YANGMeng,HEJie,HUANGXiao-jie2,CAIZhd,ZHANGLan2,SHUJun2(1.DepartmentofRespiratoryMedicine,China—JapanFriendshipHospital,Be~jing,100029;2.InstituteofClinicalMedicine,China-JapanFriendshipHospital,Beijing,1005、029)ABSTRACT:ObjectiveToexplorethepossibleroleof一6754G/5GPAI一1polymorphisminasthmaticremodeling.MethodsGenomicDNAwasisolatedfromtheperipheralbloodof30chron—icpersistentasthmaticsand20healthysubjectsfor3groups.ThePAI一14G/5Ggenotypesweredeterminedbyanallele—specificpolyme6、rasechainreaction.EveryoneperformedHRCTfortheeval—uationoftheseverityofasthmaandairwayremodeling.Quantitativeassessmentwasusedtoanalyzethethicknessofairwaywall(T,T/I))andairwaywallarea(WA,WA%).LevelsofPAI一1,TGF一81andMMP一9inplasmaweredetectedbyELISA.ResultsLevelsofTGF_,T7、andWA%for4G/4GgenotypeofPAI一1weresignificantlyhigherthanthoseof4G/5Gand5G/5Ggenotype(P<0.05).MorningplasmaPAI一1concentrationwascorrelatedsignificantlywithTGF—l31(r=0.335,P<0.05),butnotwithT,T/D,WAandWA%(P>0.05).Multivariateanalysisofvari—anceusingT,T/I),WA,WA%asdependen8、tvariablesandage,gender,group,indexofsmok—ing,courseofdisease,PAI一1genepolymorphism,plasmaPAI—l,TGF—landplasma
