Objective To explore the abnormally functional brain regions of female patients with depression by resting state functional magnetic resonance imaging (fMRI),and analyze the correlation with the severity of depressive symptoms.Methods 32 female patients diagnosed with depressive disorder and 40 matched healthy controls completed resting state fMRI scans.The whole brain's regional homogeneity (ReHo) and amplitude of low-frequency fluctuation(ALFF) were calculated,and the correlation analysis be tween ReHo and ALFF of brain regions with significant difference and the severity of depressive symptoms was conducted.Results Compared with control group,the left precuneus/left cuneus (MNI:-18,-81,45),bilateral precentral gyrus (MNI:-58,-5,35 and 57,-6,33),left inferior parietal lobule (MNI:-42,-36,45) and right inferior temporal gyrus(MN1:60,-45,-18) (P＜0.05,corrected by AlphaSim)in the case group showed significantly decreased ReHo,with statistical significance.Compared with control group,the left cuneus(MNI:-3,-87,30),right inferior temporal gyrus(MNI:60,-48,-18) and left precentral gyrus(MNI:-63,-3,26) (P＜0.05,corrected by AlphasSim)in the case group showed significantly decreased ALFF.The ReHo in the right inferior temporal gyrus was negative correlated with the HAMD-17 total score and retarda tion factor(r=-0.484,P=0.017;r=-0.408,P=0.048),the ALFF in the right inferior temporal gyrus was positively correlated with weight factor(r=0.574,P=0.003),and negative correlated with the number of depressive episodes(r=-0.416,P=0.043).Conclusion Female with depression in resting state have several abnormally functional brain regions and the extent of damage is correlated with the severity of depressive symptoms.Combination of the two parameters may yield a more comprehensive pathophy-siological mechanism for depressive disorder.

目的 探讨高血压共病抑郁障碍患者的执行功能损害特点.方法 将2013年1月至11月在北京大学精神卫生研究所门诊和住院患者分为4组,研究组为高血压共病抑郁40例,按性别、年龄、受教育程度匹配疾病对照组(包括高血压组35例,抑郁组32例)及健康对照组47例.所有受试者接受威斯康星卡片分类、Stroop色词干扰、连线测验、词语流畅性等神经心理学测验评估执行功能.结果 威斯康星卡片分类测验中,高血压共病抑郁组的持续错误数明显多于高血压组、抑郁组和健康对照组(P＜0.05),完成分类数在各组中最少,与健康对照组比较差异有统计学意义(P＜0.05);Stroop色词干扰测验中,共病组Stroop-C的完成时间在各组中最长(P＜0.05),正确数少于抑郁组和健康对照组(P＜0.05),共病组Stroop-CW的正确数少于高血压组和健康对照组(P＜0.05);词语流畅性测验中,共病组产生词汇量少于健康对照组(P＜0.05);连线测验中,共病组的完成时间最长,错误数最多,但与对照组差异无统计学意义.结论 高血压共病抑郁患者存在执行功能损害,其损害程度较抑郁障碍及高血压患者更明显.
