抑郁症患者情绪图片反应特征及杏仁核反应模式的研究

Objective To explore the behavioral and related amygdaiar temporal response to emotional pictures in individuals with major depressive disorder(MDD).Methods Functional magnetic resonance imaging(fMRI)was adopted to examine the neural substrates of emotional pictures processing in 12 first-episode unmedicated MDD subjects(MDD)and 13 healthy controls(HC).Analyses were focused on the temporal dynamics of the blood-oxygen level dependant(BOLD)signal change in the amygdala across blocks of positive,neutral and negative emotional pictures.The crude score to emotional pictures was also recorded.Results(1)The crude score wag(6.6 ±0.2)to positive pictures and(4.7 ±0.1)to neutral pictures in depressed subjects,lower than that in HC(P＜0.01),and(3.4 ±0.3)to negativc pictures in depressed subjects,which was higher than that in HC(2.2±0.2,P＜0.01).(2)The bilateral amygdala showed attenuated and delayed response to the positive pictures.in which the right amygdala showed"group×time"interaction effect to positive pictures(P=0.002).For the negative pictures,there was"group×time"interaction effect in the left amygdala(P=0.008)and group main effect in the right amygdaia(P=0.007),with the attenuated BOLD signal change in MDD group.Conclusions It suggests that amygdala is one of the key neural substrates to the character of the depressed mood or loss of interest in individuals with MDD.Depressed subiects show the attenuated and blunted behavioral and amygdala response to emotional stimuli,which support the hypothesis of the unspecially blunted emotional response in major depressive disorder.

自尊水平对大学生自我评价的影响研究

目的探讨在不同社会比较类型中,大学生自尊水平与自我评价的关系。方法采用Rosenberg编制的自尊量表,Judge等编制的核心自我评价量表和社会比较后自我评价量表,对重庆4所高校300名大学生进行调查。结果高自尊水平被试的核心自我评价得分明显高于中等自尊水平和低自尊水平被试,不同自尊水平的被试核心自我评价得分差异有统计学意义(F=157.02,P0.01);不同自尊水平的被试在不同社会比较中自我评价得分差异均有统计学意义(F=17.39,32.20,P0.01)。在上行社会比较中,高自尊水平被试自我评价得分明显高于中等自尊水平和低自尊水平被试;在下行社会比较中,高自尊水平被试自我评价得分明显高于中等自尊水平和低自尊水平被试,中等自尊水平被试自我评价得分明显高于低自尊水平被试。结论在社会比较中,自尊水平与自我评价存在正相关,且自尊水平对自我评价具有显著的预测性。

脑电联合同步功能MRI在局灶性癫痫检测中的应用价值

目的探讨脑电监测模式的脑电同步功能MR成像（EEG-fMRI）技术在局灶性癫痫患者间期痫样放电引起的脑区激活情况的应用价值。方法对12例局灶性癫痫患者进行EEG-fMRI数据采集；以间期痫样放电的事件相关设计模式对fMRI数据进行分析，观察癫痫放电引起脑激活的时空分布情况。并与MR结构成像病灶定位结果进行对比。结果12例患者中，共采集到10例患者的18次有效EEG-fMRI数据。与结构病灶相对比，11次数据显示定位结果较好，5次结果尚可，2次结果不佳；其中6例患者2次采集的定位结果相同。18次扫描结果均显示激活大脑对侧的小脑有稳定的激活；10次结果中丘脑有正激活信号，9次有位于典型的缺省状态分布脑区的负激活信号。结论EEG-fMRI技术利用多模态神经成像技术的优点，在癫痫的研究方面有较大的应用价值。     

扩散张量磁共振成像数据集的多纤维扩散各向异性研究

目的研究扩散各向异性与单体素多纤维分叉的关系。方法提出了一种基于表观扩散系数和球谐函数的多纤维扩散各向异性分析方法对扩散各向异性进行分类。通过对5例孤独症患者和5例正常儿童的扩散张量成像数据分析,从而有效地解释了部分各向异性改变与体素内多纤维分叉现象之间的关系。结果1）单体素内多纤维分叉可能会导致部分各向异性FA值降低;2）单体素内多纤维分叉异常不一定会影响白质纤维的部分各向异性;3）部分各向异性降低也可能由其他原因产生。结论多纤维分叉异常是导致部分各向异性降低的原因之一,但多纤维分叉现象并不一定影响部分各向异性FA值。该方法为进一步研究精神疾病脑白质扩散各向异性的异常改变提供了一种有效的工具。
