摘  要:目的应用静息态功能磁共振功能连接技术,探讨脑梗死后运动性失语患者脑功能的恢复机制。方法选取脑梗死后运动性失语症患者10例(失语组),同期无失语患者10例(对照组),均进行静息态fMRI检查;失语组患者1个月后行第二次fMRI检查。使用SPM8软件和DPARSF软件对数据进行后处理,选择左侧额中回(LFMG)后部作为种子点进行功能连接分析,利用REST行配对和两样本t检验。结果与对照组相比,失语组(康复治疗前)LMFG—ROI功能连接增强的脑区为右侧岛叶(MNI:x,y,z:45,12,0,t=7.98)、右侧额下回(三角部、眶部、岛盖部)(MNI:x,y,z:42,6,27,t=6.75)、右侧颞上回和颞中回(MNI:x,y,z:48,-45,6,t=10.57)、右侧缘上回(MNI:x,y,z:15,-66,60,t=5.59)、右侧角回(MNI:x,y,z:54,-50,12,t=9.55),功能连接减少的脑区为左侧扣带回后部(MNI:X,Y,z:6,-75,9,t=-10.05)和左侧楔前叶(MNI:x,y,z:-6,-69,33,t=-9.07);失语组(康复治疗后)与对照组相比,LMFG—ROI功能连接增强的脑区为左侧尾状核头部、左侧额中回和额下回、左侧苍白球、左侧中央前回和中央后回、左侧岛叶,功能连接减少的脑区为右侧海马、左侧小脑、右侧舌回、左侧扣带回后部、右侧枕叶、右侧楔前叶;失语组患者康复治疗前后比较,LMFG.ROI功能连接增强的脑区为左侧额中回(MNI:x,y,z:-51,15,24,t=-15.87)、左侧额顶叶岛盖(MNI:x,y,z:-24,-66,42,t=5.20)、左侧中央前回和中央后回(MNI:x,y,z:-15,-16,55,t=-6.53),减低的脑区为右侧颞上回、颞中回(MNI:x,y,Z:57,-18,30,t=-15.21)、右侧岛叶(MNI:x,y,z:-24,-66,42,t=-5.20)、右侧缘上回(MNI:x,y,z:15,-66,60,t=-7.69)。结论左侧大脑半球损伤�Objective To investigate the recovery mechanism of brain function in patients with motor aphasia after cerebral infarction by resting-state functional magnetic resonance imaging (fMRI) functional connectivity. Methods 10 patients with aphasia after cerebral infarction (aphasia group), and 10 patients without aphasia (control group)in the same period were enrolled.Both patients underwent resting-state fMRI examination.Patients with aphasia received a second fMRI examination 1 month later.The SPM8 software and DPARSF software were used to process the data.The back of the left middle frontal gyms (LFMG) was selected as the seed point for functional connectivity analysis.REST was used for pairing and two-sample t-tests.Results Compared with the control group,the brain regions with increased LMFG-ROI functional connectivity were right insula ( MNI : x, y, z : 45,12,0, t = 7.98 ), right inferior frontal gyms ( triangular, ankle, island cap) ( MNI : x, y, z : 42,6,27, t = 6.75 ), r:-ht upper temporal gyms and right middle temporal gyms ( MNI : x, y, z :48, -45,6, t = 1 0.57 ), right superior border gyrus ( MNI : x, y, z : 15, - 66,60, t = 5.59 ) and right angle gyrus ( MNI : x, y, z : 54, - 50, 12, t = 9.55 ) in the aphasia group ( before rehabilitation ), and the brain regions with reduced functional connectivity were left posterior cingulate gyrus ( MNI : x, y, z : 6, - 75,9, t = - 10.05 ), and left anterior wedge lobe ( MNI : x, y, z : -6, -69,33, t = -9.07 ). Compared with the control group, the brain regions with enhanced LMFG-ROI functional connectivity in the aphasia group (after rehabilitation 1 month) included head of left caudate nucleus,left middle frontal gyrus and inferior frontal gyms, left globus pallidus, left central anterior gyms,central posterior gyms,left insula; the brain regions with reduced functional connectivity were right hippocampus, left cerebellum, right lingual gyms, posterior left cingulate gyms, right oc
