急性心肌梗死患者循环血和尿心肌特异性microrna 208a水平的变化-changes of circulating blood and urine myocardial specific microrna 208a levels in patients with acute myocardial infarction
急性心肌梗死患者循环血和尿心肌特异性microRNA-208a水平的变化中文摘要目的观察心肌特异性的microRNA-208a(miR-208a)在急性心肌梗死(AcuteMyocardiumInfarction,AMI)患者循环血和尿中的含量变化,探讨血和尿中miR-208a含量在AMI早期诊断中的作用。方法采集AMI患者发病12小时内的外周血和尿,用实时荧光定量PCR(Real-timequantitativePolymeraseChainReaction,QRT-PCR)法检测血和尿中miR-208a含量,并同时用采用化学发光免疫分析法检测血cTnI、CK-MB含量。以健康者的血和尿作为对照。结果在PCR60个循环内,健康对照者血和尿中未能检出miR-208a;实验组患者血可检测出miR-208a。即使以健康对照者血miR-208aCT值60为基础进行统计,T其相对含量至少高于健康对照215倍以上,两组C值比较差异有统计学意义(P0.01);实验组患者尿中未能检测到miR-208a。结论血心肌特异性的miR-208a可作为急性心肌梗死患者敏感的生物学标志。关键词急性心肌梗死miR-208a肌钙蛋白I肌酸激酶同工酶本课题受四川省科技厅国际合作课题资助(2011HH0031)ChangeofCardio-specificMicroRNA-208alevelinBloodandUrineinAcuteMyocardialInfarctionPatientsAbstractObjectiveToobserveplasmaorurinecardio-specificmicroRNA-208alevelsinacutemyocardialinfarctionpatients,andtoexploretheeffectofplasmaorurinecardio-specificmicroRNA-208a(miR-208a)levelsintheearlydiagnosisofacutemyocardialinfarction(AMI).MethodsWeassessedtheplasmaandurinemiR-208aconcentrationswithin12hafterAMIinAMIpatients,healthyindividualsascontrol.PlasmamiR-208aconcentrationsweremeasuredwithareal-timereverse-transcriptionPCR(qRT-PCR),plasmacardiactroponinI(cTnI)orcreatinekinase-MB(CK-MB)concentrationsweremeasured.ResultsPlasmamiR-208aconcentrationsweredetectedinallindividualswithAMIwithin60PCRcycle(limitofdetection),butwerebelowthelimitofdetectionforallindividualsinthenormalhealthgroups,andtheplasmamiR-208arelativelevelsareatleastmorethan215foldcomparedwithnormalhealthpersons;UrinemiR-208aconcentrationswereundetectedinallindividualswithAMIornormalhealthpersons.ConclusionPlasmacardio-specificmiR-208alevelsmaybeasensitivebiomarkerofacutemyocardialinfarctionpatients.KeyWordsAMI;miR-208a;cTnI;CK-MB前言心肌损伤是临床急性心肌梗死最常见的表现方式,是死亡率最高的心血管疾病之一[1]。早期识别并及时采取干预措施,是提高AMI患者生存率的重要保障。目前,测定血清心肌损伤标志物--心肌酶学值是使用广泛有效的实验室诊断方法。但近年研究发现酶学检查尚存在特异性差,持续时间短等缺点,需要通过多次测定才能解决诊断问题。尽管目前已有多种方法用于诊断急性心肌梗死,但人们仍在寻找更特异的心脏损伤标志物。除心肌酶外,对心肌细胞内microRNAs(miRNA)的研究是目前的一个热点。microRNAs(miRNAs)是近年发现的一类细胞内小的非编码RNAs,它通过对mRNA切割来抑制其翻译达到对其靶目标mRNA的负反馈调控作用[2],可直接调节大约30%的细胞内基因,是正常发育、生理和疾病状态包括肿瘤和
