2、实讨结参综英致静息态功能核磁对神经精神性狼疮的应用研究摘要背景:神经精神性狼疮(NPSLE)是系统性红斑狼疮(SLE)的常见并发症,是SLE重要死因之一。由于NPSLE临床表现多样,早期诊断困难。研究表明,SLE的脑功能变化可于脑器质性损害甚至神经精神症状之前出现。目的:通过静息态功能性核磁共振对NPSLE患者及有NPSLE相关因素但无神经精神症状的系统性红斑狼疮(HRSLE)患者的大脑功能进行全面测试(包括局部功能和全脑功能联系),以便全面了解NPSLE可能的大脑功能改变,为NPSLE的早期预测和早期诊断提供有意义的影像指标。方法:筛选①11名NPSLE患者;②9名具有NPSLE相关因
3、素(抗rRNP抗体阳性,或抗磷脂抗体阳性,或有狼疮视网膜病变)但临床无神经精神症状的HRSLE患者;③12名健康对照。记录其静息态下血氧依赖性功能核磁(BOLD—fMRI)信号,利用SPM8软件包获得其局部一致性分析(ReHo)图、分数低频振幅(fALFF)图以及度中心度(DC)图,使用独立t检验对3组图像进行分析,获得3组之间T值参数图。分析不同组间对比图像的差异,分析NPSLE及HRSLE的局部功能及功能联系的改变。结果:1)项下小叶、左颞下回、左内侧额上回、左中央后回在NPSLE组、HRSLE组ReHo值显著低于HC组,其中左缘上回在NPSLE组显著低于HRSLE组(P4、,其中左缘上回在NPSLE组显著低于HRSLE组(P(O.01)。2)顶下小叶、右背外侧额上回、右额中回在NPSLE组、HRSLE组fALFF值显著低于HC组(P5、。stateImaginginNeuropsychiatricFunctionalMagneticResonaceSystemicLupusErythematosusAbstractBackground:Neuropsychiatricsystemiclupuserythematosus(NPSLE)isthecommoncomplicationofsystemiclupuserythematosus(SLE)andrepresentsanimportantcauseofmorbidityandmortalityinpatientswithSLE.ThediagnosiSofNPSLEi6、sdifficultduetocomplictedclinicalpresentations.StudieshaveshownthatfuntionaldamageresidespriortoorganiclesionsandevenneuropsychiatriCsymptoms.Objective:tofindevidenceforearlydiagnosiSofNPSLEbyusingresting——statefMRIinNPSLEpatientsandhighriskSLEpatientswithoutneuropsychiatricsymptoms(HRSLE).Method7、s:l1NPSLEpatients,9SLEpatientswithanti—ribosoproteinPantibodyoranti——phospholipidantibodyorretinalvasculopathyandwithoutneuropsychiatricsymptoms,and12healthcontrol(HC)wereenrolled,andperformedresting—statefMRIscanning.
