Objective To investigate the changes of hypothalamic-pituitary-adrenal axis (HPA)function, volume of the hypothalamic, pituitary and adrenal glands in elderly patients with depression. Methods Twenty-five cases of elderly patients with depression and 19 healthy elderly patients were enrolled into the patient group and the healthy control group, respectively. Enzyme linked immunosorbent assay was used to measure the level of the main hormone related with HPA axis in blood. The low dose dexamethasone suppression test was used to assessassessment the negative feedback regulation of HPA axis. The volume of the hypothalamus, pituitary and adrenal glands were determined by the magnetic resonance imaging. Results The Beck Depression Scale (BDI-II) and Montgomerie Rating Scale (MADRs) score of the elderly depression patients were significantly higher than those in the healthy control group (P < 0.01). The values of main hormone related with HPA axis in the patient group, such as CRH, ACTH and CORT, were higher than those in the healthy control group (P<0.01). The non- suppression rate of low dose dexamethasone suppression test in the patient group was significantly higher than that in the healthy control group (P < 0.05). The hypothalamus, pituitary and adrenal gland volume of patients group were 4.7%, 18.3% and 17.5% ,respectively. Significant the differences of pituitary and adrenal volume were observed between two groups (P < 0.05). Conclusion The levels of main hormone related with HPA axis in the elderly patients with depression were significantly increased, the non-suppression rate of low dose dexamethasone suppression test was also increased. Meanwhile, the volume of pituitary and adrenal gland in the elderly patients with depression increased.

Objective To explore the cool execution function (CEF)and its influence factors before and after treatment in drug-na?ve, first-episode schizophrenics. Methods Twenty-one drug-naive, first-episode schizophrenics (patients group) and 25 healthy persons (control group) were interviewed by using the SCID. The severity of clinical symptoms was respectively assessed in patient group before treatment and after 8 weeks using the Positive and Negative Syndrome Scale (PANSS). The Trail-Marking Test A-B (TMT A-B) and Hanoi Tower Test (HTT) were conducted to assess cool executive function. Reaction time and the number of errors of TMT A-B’s and HTT’s reaction time and operative steps were recorded. Results Before treatment, the patient group’s reaction time was longer in HTT and TMT A-B than that in the control group's (P = 0.013;P = 0.000;P =0.001), respectively. Error number of TMT-B in the patient group was more than that in the control group (P =0.015); The operative steps of HTT and error number of TMT A were no statistical difference than those in the control group. After treatment, reaction time of TMT A reduced significantly than before treatment (P = 0.002);Before and after treatment , patients ’ reaction time of HTT and TMT B , operative steps of HTT and the error number of TMT A-B were all no statistical difference. Running multiple linear regression , reaction times of TMT-B was positively correlated with negative symptoms (β = 7.198,P = 0.012), and the error number of it was positively correlated with positive symptoms (β = 0.382,P = 0.024). Conclusions CEF in patients with drug-naive, first-episode schizophrenia is affected in a certain degree, especially the flexibility and attention transfer. Symptoms is the most serious influence factors. Treatment in sympotoms earlier is the important way to protect cool cognition.

Objective To investigate the spontaneous activity of brain neurons in patients with obsessive-compulsive disorder (OCD) under resting state. Methods Forty-eight OCD patients and 50 age-, gender- and year of education-matched normal controls were enrolled. All the subjects underwent 3.0 T fMRI to acquire resting state brain image. The brain regions with significant differences in amplitude of low-frequency fluctuation (ALFF) between patients and controls were analyzed. Whole-brain functional connectivity (FC) were analyzed using the brain regions with significant differences as seed points, and the correlation between brain regions with significant differences in ALFF and FC analysis and obsessive-compulsive symptoms was analyzed. Results Compared to the control group, the ALFF of left dorsolateral prefrontal cortex increased in patients with OCD (t=4.305, P<0.001). Compared to the controls, the analysis of whole-brain FC (based on MNI template) with the left dorsolateral prefrontal cortex as the regions of interest showed that the FC strength between the left dorsolateral prefrontal cortex and right orbital inferior frontal cortex (t=3.897, P<0.001), left anterior cingulate cortex (t=3.370, P<0.001), right anterior cingulate cortex (t=4.299, P<0.001), left middle cingulate cortex (t=3.220, P<0.001), right middle cingulate cortex (t=4.607, P<0.001) enhanced; the FC strength between the left dorsolateral prefrontal cortex and the left opercular part of inferior frontal gyrus (t=-4.630, P<0.001) weakened in patients with OCD. The FC between the left dorsolateral prefrontal cortex and the left opercular part of inferior frontal gyrus was negatively correlated with obsessions score(r=-0.369, P=0.014), compulsions score (r=-0.392, P=0.009) and total score (r=-0.393, P=0.008) of the Yale-Brown obsessive compulsive scale (Y-BOCS). Conclusion In patients with OCD, spontaneous neural activity of the left dorsolateral prefrontal cortex is enhanced in resting state, and the FC with multiple brain regions is abnormal. The FC strength between the left dorsolateral prefrontal cortex and the left opercular part of inferior frontal gyrus is associated with obsessive-compulsive symptoms.

Objective:To explore the functional connections of the whole brain and the two hemispheres in patients with obsessive-compulsive disorder (OCD).Methods:Twenty-six patients with obsessive-compulsive disorder(patients group) and thirty-seven healthy controls matched in gender, age and education(control group) were enrolled.All the participants accepted the resting-state functional magnetic resonance (rs-fMRI) scan.Based on DPABI and REST software, degree centrality (DC) and voxel - mirrored homotopic connectivity (VMHC) approaches were used to explore the pattern of functional connection in OCD.Results:Compared with the control group, the DC values in the right posterior cerebellar lobe(MNI: x, y, z=45, -87, -12), left precentral gyrus(MNI: x, y, z=-54, 9, 39), left inferior parietal lobule(MNI: x, y, z=-48, -51, 42), right anterior cingulate cortex(MNI: x, y, z=3, 18, 48) were significantly higher( t values were 5.75, 5.26, 5.28 and 5.16, respectively), and the DC values in the left inferior frontal gyrus(MNI: x, y, z=-36, 9, 30) were significantly lower( t value was -6.65) in patients group.The VMHC values in bilateral posterior cerebellar lobe(MNI: x, y, z=±51, -69, -33), bilateral inferior parietal lobule(MNI: x, y, z=±48, -51, 54), bilateral anterior cingulate cortex(MNI: x, y, z=±3, 21, 45)in patients group were significantly higher that those in control group( t values were 5.19, 5.19, 5.02, 5.02, 5.15 and 5.15, respectively). The DC and VMHC values in patients group were not significantly correlated with clinical symptoms(-0.23< r<0.19, P>0.05). Conclusion:OCD patients have abnormal connections between key brain network nodes and relevant brain regions, and functional connections have increased among multiple cerebral hemispheres.

Objective To explore the association between the structural patterns of orbitofrontal sulcogyral pattern (OSP)and the susceptibility to schizophrenia in children and adolescents patients with schizophrenia. Methods Seventy-two childhood and adolescence schizophrenia aged 6~18 years were enrolled as the case group and 78 sex-, age-, education-matched healthy children served as the control group. MR images were acquired with a 3.0 T Magnetom Symphony MRI system. Positive and Negative Syndrome Scale (PANSS) was used to evaluate the symptom severity of patients.The pattern type of OFC was classified based on continuity among medial (MOS),lateral (LOS)and transverse (TOS) orbital sulci according to the method of Chiavaras and Petrides'. The orbitofrontal cortex (OFC) sulcogyral pattern was classified into three types(TypeⅠ,TypeⅡ,TypeⅢ)in each hemisphere. Results There were significant differences in the distribution of OFC patterns between the control and the case group (Left hemisphere: Χ2=6.668,P=0.036; Right hemisphere: Χ2=7.501,P=0.024). The linear regression analysis showed that Type Ⅲ in either hemisphere was associated with more severe symptoms in schizophrenia patients (B=7.214, P=0.008). Conclusions Type Ⅲ sulcogyral pattern may be a morphological risk marker for schizophrenia. Compared to the other two types, the Type Ⅲ expression is associated with more severe clinical symptoms.

Objective To investigate the characteristics of amygdala neural circuitry in comorbidity of late-life depression (LLD) and cognitive impairment. Methods Twenty-four LLD,eighteen amnestic mild cognitive impairments (aMCI),thirteen aMCI with depression (dMCI) and thirty cognitive normal (CN) subjects completed resting-state functional magnetic resonance imaging scan. Main effects of depression and MCI and their interactions on the intrinsic amygdala functional connectivity network ( AFCN) connectivity were examined. Behavioral significance of AFCN that voxel-wised amygdala connectivity correlating with de-pression severity and memory scores were also tested after controlling the effects of covariates,including age, gender,education, gray matter atrophy, and group. Results The immediate memory and delayed memory function in the aMCI group (-0. 75 ± 0. 77 and -1. 13 ± 0. 56) and the dMCI group (-1. 07 ± 0. 79 and-1. 00±0. 52) were significantly lower than those of the CN group (0. 46±0. 73 and 0. 60±0. 61),and the difference was statistically significant (P<0. 01). Depression and anxiety in the LLD group (1. 00±0. 53 and 0. 93±0. 98) and the dMCI group (0. 86±0. 80 and 0. 78±0. 82) were significantly higher than those of the CN group (-0. 92±0. 25 and -0. 74±0. 22),and the difference was statistically significant (P<0. 01). Brain network analysis showed that separated neural circuits were implicated in the depression and cognitive im-pairment. Importantly,interactive effects of depression and MCI on the AFCN were also identified,especially in the bilateral somatomotor area,inferior parietal cortex/precuneus,posterior cingulate cortex,right medial prefrontal cortex/dorsolateral prefrontal cortex and hippocampus. Behavioral significance of AFCN also re-vealed the distinctive neural circuits involved in the depression severity and memory deficits,respectively. Conjunction analysis further identified the overlapped neural circuits associated with depression and memory deficits were primarily in the left DLPFC,insula,hippocampus,right inferior prefrontal cortex and dorsomedi-al prefrontal cortex. Conclusions Depression and cognitive impairment synergistically facilitate functional decoupling of AFCN and thus compromise the integrity of amygdala networks. Distinct depression-related or MCI-related neural constructs represent the characteristics of clinical phenotype of depression or MCI alone, while overlapped circuits probably reveal the neural basis of comorbidity of LLD and MCI.
