RESULTS:①MRI scanning from coronal section: after 10 mL contrast-medium injection, in the center of medial knee joint, high visual signal was seen in the cavity of joint; after 15 mL contrast-medium injection, scanning between femora and patella, high visual signals were observed; after 20 mL contrast-medium injection, scanning by posterior internal and external condyle of knee, high visual signals were found in 80% of internal and external recess of posterosuperior of thighbone.

结果：①在膝关节冠状面MRI扫描：注入10 mL对比剂时，经膝关节内侧中点处，关节腔内均可见高信号；注入15 mL对比剂时，经股骨和髌骨间，关节腔内均可见高信号；20 mL对比剂时，经股骨内、外侧髁后缘处，80%股骨后上内、外侧隐窝内出现高信号。

Compared to healthy controls, GTCS presented decreased gray matter volume in the bilateral thalamus, frontal lobe, insula and cerebellum regions. There were no regions showing significant increased gray matter volume. Correlation analysis revealed that bilateral thalamic, left medial frontal gyrus, left middle frontal gyrus and left precentral gyrus GMV had negative correlations with the frequecy of epilepsy.

通过GTCS患者组与正常对照组的比较，发现GTCS患者的双侧丘脑、双侧额叶、双侧岛叶、双侧小脑等区域的灰质体积有比较明显的减小，但没发现有意义的灰质体积增高的区域；患者双侧丘脑、左侧中央前回、左侧额内侧回、左侧额中回和其发病频率呈负相关，没有正相关的区域。

3D MDD patients showed significantly lower gray matter density than controls in right medial frontal gyrus, right temporal pole, bilateral putamen and globus pallidus, bilateral cerebellum. After treatment, gray matter density in right superior frontal gyrus, bilateral precentral gyrus, temporal pole, putamen and globus pallidus, and cerebellum in patients were still significantly lower than controls.

发作期抑郁症患者右侧额内侧回和同侧颞极、双侧壳核/苍白球和双侧小脑的灰质密度较正常人低；治疗后右侧额上回、双侧中央前回、双侧颞极、双侧壳核/苍白球和双侧小脑的灰质密度仍较正常人低。

Campared among the three match conditions,there are more activation levels of non-matches than identical matches in precuneus,and there are more activation areas for non-matcher than that of the categorical matches in frontal,occipital and medial temporal lobes.

从三种匹配条件之间的差异来看，不匹配和名字匹配相比，在楔前叶的激活显著；而不匹配与类别匹配相比，在额区、枕区和内侧颞区都有激活。

Results:The results largely conformed to previous studies and further confirmed the role of hippocampus, precuneus and posterior cingulate cortex in aMCI patients at rest,as well as that of the frontal lobe and medial temporal lobe structures in episodic memory.

在完成情节记忆任务过程中，aMCI患者的额叶、顶下小叶、海马、海马旁回和扣带回的激活较正常人增加；除顶下小叶外，其他区域局部亦表现为较正常人激活降低。

Compared to the controls, the patients exhibited decreased ReHo mainly in the precuneus, medial prefrontal cortex, bilateral middle temporal gyrus and middle frontal gyrus; while the increased ReHo was mainly distributed in the subthalamus.

结果表明：在静息状态下，患者大脑的局域一致性在某些脑区较正常人低，主要集中在楔前叶、内侧前额叶、双侧颞叶、双侧额中回；另外，在某些脑区较正常人高，主要集中在底丘脑等中缝核团。

Previous studies have identified that understanding other's mind engages a neural circuit consisting of the medial prefrontal cortex, temporoparietal junction, superior temporal sulcus, temporal pole, and precuneus/posterior cingulated cortex. However, due to the limitation of experimental paradigms and neuroimaging data analysis approach, the exact neurocognitive mechanisms that underlie the understanding of others' belief remain unclear.

尽管前人的研究已发现内侧前额叶、颞顶联合皮层、后扣带回/楔前叶以及颞上沟等脑区参与他人信念理解，但是，由于实验范式本身和脑成像数据分析方法的局限性，过去的研究工作没有提出准确的认知神经机制来解释相关脑区组成的神经网络如何协同工作、完成视角转换以保证正确理解他人的信念。

Comparison results revealed that there was significantly reduced functional connectivity in the left posterior cingulate cortex, vbilateral anterior cingulate cortex, bilateral medial prefrontal cortex, left parahippocampal cortex in MHE patients, while functional connectivity increased in the right precuneus.

但与正常对照组相比，MHE患者大部分脑缺省模式网络脑区功能连接降低，包括：左侧后扣带回、双侧前扣带回、双侧额中回、左侧海马旁回；而右侧楔前叶的功能连接较正常对照组升高。

On the contrary, more significant activations by English familiar voices were observed in the left precuneus, middle frontal gyrus and left posterior cingulate cortex as compared with Chinese familiar voices; For Chinese unfamiliar voices, more significant activations were observed in the right middle temporal gyrus and right medial frontal gyrus than for English unfamiliar voices.

结果： 汉语熟悉声音较英语熟悉声音显著激活脑区位于右颞上回；英语熟悉声音较汉语熟悉声音显著激活脑区位于左楔前叶、额中回和左后扣带回；汉语不熟悉声音较英语不熟悉声音显著激活脑区位于右颞中回和右额叶；英语不熟悉声音较汉语不熟悉声音位于右额下回、额中回和左颞中回。
