摘要:
目的　利用静息态功能磁共振成像中的分数低频振幅（fractional amplitude of low frequency fluctuation，fALFF）技术研究中高度近视患者的脑功能改变，探讨其与近视患者临床资料的相关性。方法　选择21例中高度近视患者为近视组，选择21名年龄、性别相匹配的健康志愿者为正常对照组，对入选者行静息态功能磁共振fALFF扫描。比较近视组与正常对照组大脑功能活动fALFF值的差异，并且分析fALFF改变的脑区与近视患者临床资料的相关性。结果　相比于正常对照组，近视组在左侧额下回、壳核与右侧额下回、壳核、岛叶等区域fALFF值显著减低（均为P＜0.05），然而双侧中扣带回、双侧前扣带回、左侧中央后回以及左侧顶上小叶等区域fALFF值显著增高（均为P＜0.05）。在近视组中，患者大脑不同区域的平均fALFF值与其病程、屈光度及最佳矫正视力均无明显相关性（均为P＞0.05）。结论　近视患者伴随着多个脑区的神经元活动异常，这些脑区异常可能反映近视患者在语言理解和注意力控制方面可能存在功能障碍。
Abstract:
Objective　To investigate the changes of brain function in moderate and high myopia patients using fractional amplitude of low frequency fluctuation (fALFF),and discuss the correlation between brain function changes and clinical data of patients with myopia.Methods　Totally 21 moderate and high myopia patients (myopia group),and 21 healthy volunteers (normal control group) who were matched with myopia patients in age and gender,were selected to take rs-fMRI examination.The difference of fALFF of brain functional activity in patients with myopia and normal controls was compared,and the correlation between the changes of fALFF and clinical data of patients with myopia was analyzed.Results　Compared with normal control group,the fALFF values of myopia group in the region of the left inferior frontal gyrus,putamen and right inferior frontal gyrus,putamen and insula were significantly lower (all P<0.05,AlphaSim corrected).However,in bilateral cingulate gyrus,bilateral anterior cingulate gyrus,left postcentral gyrus,left superior parietal lobule and region,fALFF values were increased (all P<0.05,AlphaSim corrected).Conclusion　Patients with myopia are accompanied by abnormal neuronal activity in many brain areas,which may reflect the dysfunction of language understanding and attention control in myopic patients.
