ABSTRACT

ZNF804A rs1344706 has been identified as one of the risk genes for schizophrenia. However, the neural mechanisms underlying this association are unknown. Given that ZNF804A upregulates the expression of COMT, we hypothesized that ZNF804A may influence brain activity by interacting with COMT. Here, we genotyped ZNF804A rs1344706 and COMT rs4680 in 218 healthy Chinese participants. Amplitudes of low-frequency fluctuations (ALFFs) were applied to analyze the main and interaction effects of ZNF804A rs1344706 and COMT rs4680. The ALFFs of the bilateral dorsolateral prefrontal cortex showed a significant ZNF804A rs1344706 × COMT rs4680 interaction, manifesting as a U-shaped modulation, presumably by dopamine signaling. Significant main effects were also found. These findings suggest that ZNF804A affects the resting-state functional activation by interacting with COMT, and may improve our understanding of the neurobiological effects of ZNF804A and its association with schizophrenia.

ABSTRACT

Objective To investigate gender differences of plasma glial cell line-derived neurotro-phic factor (GDNF) levels in patients with major depressive disorder (MDD). Methods MDD subjects (male 20,female 36) and healthy controls (HCs) (male 35,female 45) were divided into four groups by gender. Plasma levels of GDNF were measured and compared in different gender groups. The clinical symp-tom severity of MDD patients was evaluated by 17-item Hamilton Depression Scale (HAMD-17) and Hamil-ton Anxiety Scale (HAMA-17). Results (1)The plasma GDNF level in male patients with major depres-sive disorder (( 1. 55 ± 0. 43 ) pg/ml ) was significantly lower than that in healthy controls (( 1. 86 ± 0. 50)pg/ml,F=4. 64,P=0. 036). There was no significant difference in GDNF level between female de-pression patients((1.62±0.46)pg/ml)) and female healthy control((1. 64±0. 48)pg/ml,F=0. 18,P=0. 672). In HCs,the GDNF level of male was significantly higher than that of female((1. 86±0. 50)pg/ml, (1. 64±0. 48)pg/ml,F=2. 04,P=0. 045). There was no significant difference in GDNF level between male and female patients(P>0. 05). (2) GDNF level in male patients with major depressive disorder was nega-tively correlated with HAMA score(r=-0. 388,P=0. 034). Conclusion The expression of GDNF is affect-ed by sex factors,which may be related to the different pathogenesis of MDD.

ABSTRACT

Objective To find frontal lobe-amygdala functional connections in different age paragraph female patients with bipolar disorder. Methods The FMRI date were acquired from 30 patients with bipolar disorder aged 13 to 25 years old and 30 age-and education level-and gender-matched health controls.FMRI was also conducted on 30 patients with bipolar disorder aged 26 to 45 years old and 30 age-and education level-and gender-matched health controls.The date was calculated by using MATLAB based DPARSF software. Results Compared with corresponding health controls, the lobe-amygdala functional connections significantly decreased in patients aged 13 to 25 years but remained unchanged in patients aged 26 to 45 years old. Conclusions The decrease in the frontal lobe-amygdala functional connections decreased in female patients aged 13 to 25 years old may be related to the underdevelopment in vulnerable immature brain.In contrast, the frontal lobe-amygdala functional connections in female patients aged 26 to 45 years old remain intact.

ABSTRACT

Medical psychology and psychiatry is the obligatory courses for five-year and seven-year medical students. With the rapid changes of society and continuous improvement of medical services , it is necessary to adjust and integrate the teaching content of these two courses. Teaching order of some chapters in the teaching syllabus was not helpful for students to understand the teaching content. Some teaching content was repetitive. Part of the self-study content urgently needs to teach with the development of the society and changes in disease spectrum. After the adjustment , the teaching content of the curricu-lum with strong pertinence was clear and coherent. It improved the teaching efficiency and knowledge of students;therefore, the curriculum is widely praised by the students.

ABSTRACT

Objective To research the changes of regional gray matter volumes in first-episode, medication naive females with major depressive disorder. Methods Magnetic resonance imaging and voxel-based mor-phometry were used to compare regional gray matter volumes between 14 medication-naive female participants with a first episode of major depressive disorder ( MDD) ( age( 29. 5 ±6.8) years, number of education years(11.4 ± 2. 7) years, duration of iIIness(5.4 ±5. 2 ) months, H AMD score(27.6 ±5.5)) and 14 female healthy comparison participants (HC) (age(29.5 ±6.9)years,number of education years( 12. 2 ±3. 3)years,HAMD score(2. 1 ± 1.9)). Results Volumes of bilateral anterior cingulate cortex ( ACC) and right amygdala were significantly smaller in the MDD group than those in the HC group. Conclusion These results suggest that volume reductions in ACC and amygdala in females with MDD are present at illness onset.

ABSTRACT

Objective To research the effects of tianeptine and lithium on expression of pCREB in hippocampus of chronic stress depression rats. Methods All the experimental rats were divided by random into : Group of depression,Group of tianeptine,Group of lithium and Group of control. The rats of Group of depression, Group of tianeptine and Group of lithium were applied stress for 21 days,and meanwhile Group of control had no stress. The rats of Group of tianeptine were fed with tianeptine (50 mg/kg) , Group of lithium were fed with lithium (60 mg/kg) , while another groups were fed with normal sodium of the same volume. The ethology examination was performed by using method of open-field and experiment of fluid consumption. The expression of pCREB was detected by Western-blotting method. Results After the chronic stress,the horizontal crossing numbers,the erection times,the modification times and the percentage of sacchar-consumption of the rats of Group of depression were 23.2±23.0;8. 1 ±7.2; 3.6 ±3.5 and (55.4 ±11.7)% respectively, which were less than Group of control (46.0±18.9;20.3±11.3;8.4±2.7 and (68.5 ±8.2)% ; P<0.01). The horizontal crossing numbers(28. 1 ±23.0) ,the erection times(12. 1 ± 9.4) and the modification times(5.5 ±3.2) of Group of tianeptine are less than those of Group of control (P < 0. 05), but no significant difference compared with Group of depression; the percentage of sacchar-consumption(62.7 ± 10.6) % ,Group of tianeptine was more than Group of depression (P< 0.05 ) , but no obvious difference with Group of control. The horizontal crossing numbers, the erection times, the modification times and the percentage of sacchar-consumption of Group of lithium were less than those of Group of control (P < 0.05), more than those of Group of depression but no significant difference (P > 0.05). In Westernblotting method,the level of pCREB in the hippocampus of Group of depression was less than that of Group of control (P< 0.01); that of Group of tianeptine was more than that of Group of depression (P < 0.01) but no obvious difference with Group of control; that of Group of lithium was less than that of Group of control (P<0. 01) and more than Group of depression (P<0.01). Conclusion Tianeptine could reverse the reduction of expression of pCREB in hippocampus of chronic stress depression rats and lithium partly did it.

ABSTRACT

BACKGROUND: The concern over the use of electroencephalogram (EEG)diagnosis and biofeedback training as a viable option for children with attention deficit hyperactivity disorder(ADHD) has grown gradually.OBJECTIVE: To evaluate the diagnostic accuracy and therapeutic efficacy of A620 EEG system to ADHD children.DESIGN: Prospective observation and comparative study on ADHD children.SETTING: Psychological department of a municipal hospital.PARTICIPANTS: From October 2003 to May 2004, 113 outpatient children in Psychology Hyperactivity Department of the Central Hospital of Anshan City were selected. Inclusion criteria: 6 to 14-year-old outpatient children in Hyperactivity Department. Exclusion criteria: nervous system organic diseases, pervasive developmental disorder(PDD), mental retardation, epilepsy, psychotic disorder, acoustical and visual abnormalities,etc. Of all the ADHD children, 88 were male and 25 were female, with the mean age of(10 ± 3) years.METHODS: A620 EEG system was applied to examine the 113 participants. According to the Diagnostic Criteria for ADHD in Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-Ⅳ), published by American Psychiatry Association, ADHD children were diagnosed and then the EEG diagnostic accuracy and specificity were calculated. The System was also used for biofeedback treatment on 27 ADHD children. Fluctuation of EEG θ/β value was measured both before and after treatment, and the change of hyperactivity index was investigated by Conners Parent Symptom Questionnaire as well.MAIN OUTCOME MEASURES: EEG θ/β value, Conners index of hyperactivity (CIH).RESULTS: The diagnostic sensitivity of EEG on ADHD was 83.58%, and the specificity of it was 82.61%; EEB θ/β value of post-treatment was 8.26 ±4.05, which decreased significantly compared with pre-treatment value (12.38 ± 7.96) ( t = 2. 39, P < 0.05); CIH was also dramatically declined from(24. 73 ± 10. 96) (pre-treatment) to( 12.05 ± 8.63)(post-treatment) ( t= 4.72, P < 0. 01 ).CONCLUSION: EEG can be used as an accessory method in ADHD diagnosis due to its high sensitivity and specificity. Abnormalities of brainwave and hyperactivities of ADHD patients can be greatly ameliorated by EEGbiofeedback treatment.
