目的采用情绪评估量表和任务态功能磁共振成像（Task f MRI）技术,分析库欣病（CD）患者脑功能改变及其与精神症状的关系。方法收集2015年11月-2016年11月在解放军总医院内分泌科住院诊断为库欣病的8例患者,并选取21名年龄、性别和受教育程度相匹配的健康人作为对照组,对其进行Zung抑郁自评量表（SDS）、Zung焦虑自评量表（SAS）、正性负性情绪量表（PANAS）和库欣生活质量量表（Cushing QOL）的评估,并行Task f MRI检查。结果与对照组相比,CD组患者均存在抑郁、焦虑状态,正性情绪评分低,而负性情绪评分较高。Task f MRI结果显示,观看正性图片时CD组左侧小脑和右侧中央后回激活程度较对照组减弱,左侧小脑激活程度与16：00点促肾上腺皮质激素（ACTH）水平呈正相关,右侧中央后回激活程度与尿游离皮质醇（UFC）水平呈正相关;观看负性图片时左侧小脑、双侧海马旁回和左侧额下回激活程度较对照组明显减弱,左侧小脑激活程度与0：00点皮质醇水平和焦虑量表评分呈负相关,与UFC水平呈正相关;观看中性图片时左侧小脑和左侧海马旁回激活程度较对照组减弱。结论 CD患者脑功能受损,会出现抑郁、焦虑等精神障碍,通过Task f MRI技术可发现左侧额下回、右侧中央后回、双侧海马旁回和左侧小脑激活程度减弱与之相关。

Objective To analyze the relationship between the brain functional alterations of patients with Cushing＇s disease（CD） and patients＇ mental symptom by applying the Evaluating Emotional Scales and task functional magnetic resonance imaging（Task f MRI）. Methods Task f MRI was performed on 8 patients with diagnosed CD admitted in the Department of Endocrinology of Chinese PLA General Hospital from Nov. 2015 to Nov. 2016 and 21 healthy people with matched age, gender and education level as control. Meanwhile, Self-Rating Depression Scale（SDS）, Self-Rating Anxiety Scale（SAS）, Positive and Negative Affective Scale（PANAS） and Cushing Quality of Life Scale（Cushing QOL） were obtained to assess the brain functions. ResultsSignificant depression and anxiety were observed in patients with CD, and their positive affective score was substantially lower while the negative affective score was relatively higher compared with that in the controls. Task f MRI revealed that, when watching the positive pictures, the activation degree of left cerebellum and right postcentral gyrus weakened in CD patients than in the controls, and the positive correlations existed between the activation degree of left cerebellum and the 16 o＇clock adrenocorticotrophic hormone（ACTH） level, and between the activation degree of right postcentral gyrus and the urinary free cortisol（UFC） level in CD patients. In contrast, when watching the negative pictures, the activation degree of left cerebellum, bilateral parahippocampal gyrus and left inferior frontal gyrus was weakened in CD patients than in the controls, and the activation degree of left cerebellum was negatively correlated to the 0 o＇clock cortisol level and SAS score, but is positively correlated to the UFC level. W hen watching the neutral pictures, the activation degree of left cerebellum and left parahippocampal gyrus was weakened in CD patients than in the controls. Conclusions CD patients may have impaired brain function with depression and anxiety mental
