Objective To detect the patterns of cognitive impairment between patients with paranoid schizophrenia and patients with bipolar mania by using the Cambridge Neuropsychological Test Automated Battery (CANTAB) ,and to explore research clues for finding of cognitive endophenotype in patients with paranoid schizophrenia or bipolar mania. Methods Six CANTAB subtests and the seven subtests of the Wechsler Abbreviated Scale of Intelligence (WAIS short form) were administered to 35 patients with paranoid schizophrenia and 33 patients with bipolar mania who were drug naive experiencing an acute episode, as well as 30 healthy controls. Results Patients with paranoid schizophrenia and bipolar mania demonstrated impairments in 13 of the 15 cognitive indicators in CANTAB. After controlling IQ, both patient groups remained as significantly different from normal controls in terms of search strategy(36. 8 ±3.56,37.24 ±4. 21,30. 33 ±6.24) ,between-search errors(40. 86 ± 19.97,40.24 ± 18.92,15.4 ±17.22) on the SWM test,the proportion of hits(0.54 ±0. 18,0.56 ±0.15,0.78 ± 0.17) on the RVIP test,total errors(45.26 ±36.36,46.61 ±33.32,14 ± 11.7) and EDS errors (12.43 ±9.96, 13.18 ±8.98,4.97 ±6.09)on the IED test. Between search error in the SWM test was positively correlation with YMRS scores ( r=0.38, P=0.039) in bipolar patients. Conclusion Both patient groups demonstrated a comparable profile of cognitive impairments during active periods of their condition. The cognitive impairment index may be a discreet cognitive endophenotype overlapping the disorders.

Objective To investigate gray matter structural damage in first-episode antipsychotic-na?ve patients with adolescent-onset schizophrenia. Methods Twenty-six patients with schizophrenia and 26 healthy controls were scanned by using GE 3.0T magnetic resonance imaging in order to explore brain gray matter volume (GMV) changes with registration techniques based on the latest morphological deformation field theory. The correlation of gray matter volume abnormalities with clinical severity was also analyzed. Results Compared with healthy controls, patients with adoles-cent-onset schizophrenia showed significant reduction in GMV in the left parietal lobe, parahippocampal gyrus and right cerebellar pyramis. GMV of the left parahippocampal gyrus is significantly correlated with PANSS paranoid scores (r=-0.49, P=0.02). Conclusions There is structural abnormality in GM in parahippocampal-parietal-cerebellar in pa-tients with adolescent-onset schizophrenia and the severity of paranoid symptoms is related to the reduced GMV in the left parahippocampal gyrus.

ObjectiveTo identify the metabolic alterations on prefrontal lobes and hippocampus in male patients with the first-episode mania using proton magnetic resonance spectroscopy(H-MRS).Method 18 male patients with the first-episode mania and 27 healthy subjects matched for age,gender,and years of education were included in the study.1 H-MRS was performed in two sides of the hippocampus and frontal lobes regions.The ratios of N-acetylaspartate (NAA),choline (Cho) to creatine (Cr) were measured.One-sample t test and paired-samples t test were used for statistic process.ResultsMale patients with the first-episode mania presented decreased NAA/Cr in left frontal lobe and hippocampus regions when compared to normal controls( left frontal lobe (1.68 ±0.19 vs 1.86 ± 0.19),hippocampus ( 1.32 ± 0.10 vs 1.43 ± 0.16 ),P ＜ 0.01 ),but there were no significant difference in NAA/Cr for right frontal lobe and hippocampus regions between groups ( all P ＞ 0.05 ).Two groups also showcd no significant difference for Cho/Cr in bilateral frontal lobe and hippocampus (P ＞ 0.05 ).Conclusion There is significant difference of manifestation of 1H-MRS between male patients with mania and normal controls,which reflects neuronal dysfunction in the prefrontal lobes and hippocampus.

ObjectiveTo examine biochemical characteristics of the frontal lobe and hippocampus in unaffected parentsof schizophreniaprohandsusingprotonmagneticresonancespectroscopy(1H-MRS).Method 19 unaffected fathers of schizophrenia probands with matched 19 male healthy control subjects and 24 unaffected mothers of schizophrenia probands with matched 24 female healthy control subjects were included in the study.1 H-MRS was performed in two sides of the hippocampus and frontal lobes regions.The ratios of N-Acetylaspartate ( NAA ),choline (Cho) to creatine (Cr) were measured.One-sample T test and paired-samples t test were used for statistic process.ResultsUnaffected mothers of schizophrenia probands had a higher Cho/Cr ratio ( left ( 1.10 ± 0.13,right ( 1.08 ± 0.12 ) ) in the frontal white matter compared with matched female health control subjects(left( 1.03 ± 0.10),right( 1.02 ± 0.09 )).The NAA/Cr ratio was significantly reduced in the left frontal white matter of female health control subjects compared to right( 1.64 ± 0.12 vs 1.74 ± 0.13 ),but this difference was not observed in unaffected mothers of schizophrenia probands.There were no significant differences in metabolites for frontal lobe and hippocampus regions between unaffected fathers of schizophrenia probands and male healthy control subjects groups( all P＞0.05 ).ConclusionThe results implicate that the metabolic abnormalities and disappeared asymmetry of NAA/Cr might exist in the frontal white matter among unaffected mothers of schizophrenia probands.

OBJECTIVETo explore the association of a functional polymorphism Val158Met of COMT gene and attention and executive function in first-episode treatment-naive patients with schizophrenia and healthy controls.

METHODSTrail making test (TMT) and clinical performances were evaluated in 103 first-episode treatment-naive patients with schizophrenia and 99 healthy controls. Polymorphism of COMT Val158Met was analyzed using polymerase chain reaction-restriction fragment length polymorphism method. A general linear model was used to investigate the effect of genotype subgroups on the attention and executive function.

RESULTSThere was a significant difference between control subjects and patients with schizophrenia on the TMT-A and B. However, no significant difference among Val/Val, Val/Met and Met/Met on the TMT-A and B in control subjects and patients with schizophrenia was detected.

CONCLUSIONThe association among COMT Met variant and trail making testing (attention and executive function) has been replicated. However, no association of COMT Met variant with disruption of dopaminergic influence on neurocognitive function was detected. This may be due to the heterogeneity of population.

Objective:To identify additional loci associated with depression and the hippocampus (HIP) through genome-wide association study.Methods:The depression-related genome-wide association study (GWAS) meta summary data was downloaded from the official website of the Psychiatric Genomics Consortium, which had involved 170 756 cases and 329 443 controls. The left and right hippocampal volume GWAS data sets were downloaded from the UK Biobank, which involved 33 224 participants. The conditional false discovery rate (condFDR) was used to identify novel genetic loci for depression and left and right hippocampal volumes, and a conjunctional false discovery rate (conjFDR) was used to evaluate the enrichment of pleiotropic loci between depression and left and right hippocampal volumes.Results:Respectively, 7, 13, and 12 new loci have been associated with depression, left hippocampal volume and right hippocampal volume, with a significant threshold of condFDR < 0.01. A site of rs1267073 locus was found to be shared by the depression and right hippocampal volume with a threshold of conjFDR < 0.01.Conclusion:Above findings have provided more insights into the genetic mechanisms underlying the volume of hippocampus and the risk for depression. The results may also provide evidence for future clinical trials for treating depression.

ObjectiveTo investigate the efficacy and safety of venlafaxine in the treatment of depression under the guidance of pharmacogenomics testing， and to provide references for individualized medication. MethodsA total of 66 patients who met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） for depressive episode were included in the study. Patients who were recommended to be treated with venlafaxine in the pharmacogenomics testing report were divided into study group （n=32）， and those who were decided to be treated with venlafaxine by doctors after consultation with patients were divided into control group （n=34）. At the baseline and the end of the 2^nd， 4^th， 6^th and 8^th weekend of treatment， Hamilton Depression Scale-24 item （HAMD-24） was adopted to evaluate the clinical efficacy. Meanwhile， Sheehan Disability Scale （SDS） was applied to measure the social function of patients at the baseline and the end of the 8^th weekend of treatment. After treatment， Treatment Emergent Symptom Scale （TESS） was used to assess the incidence of adverse reactions. ResultsAt the end of the 4^th， 6^th and 8^th weekend of treatment， HAMD-24 scores in the study group were all lower than those in the control group， with statistical differences （t=2.344， 4.316， 5.760， P<0.05 or 0.01）. At the end of the 8^th weekend of treatment， SDS score of the study group was lower than that of the control group， with statistical difference （t=2.173， P<0.05）. The adverse reaction rate in the study group was lower than that in the control group， with statistical difference （χ²=5.720， P<0.05）. ConclusionTreatment of depression with venlafaxine based on pharmacogenetic testing is an effective and safe way to alleviate the depression symptoms in patients.

OBJECTIVETo explore common biological pathways for attention deficit hyperactivity disorder (ADHD) and low birth weight (LBW).

METHODSThei-Gsea4GwasV2 software was used to analyze the result of genome-wide association analysis (GWAS) for LBW (pathways were derived from Reactome), and nominally significant (P< 0.05, FDR< 0.25) pathways were tested for replication in ADHD.Significant pathways were analyzed with DAPPLE and Reatome FI software to identify genes involved in such pathways, with each cluster enriched with the gene ontology (GO). The Centiscape2.0 software was used to calculate the degree of genetic networks and the betweenness value to explore the core node (gene). Weighed gene co-expression network analysis (WGCNA) was then used to explore the co-expression of genes in these pathways.With gene expression data derived from BrainSpan, GO enrichment was carried out for each gene module.

RESULTSEleven significant biological pathways was identified in association with LBW, among which two (Selenoamino acid metabolism and Diseases associated with glycosaminoglycan metabolism) were replicated during subsequent ADHD analysis. Network analysis of 130 genes in these pathways revealed that some of the sub-networksare related with morphology of cerebellum, development of hippocampus, and plasticity of synaptic structure. Upon co-expression network analysis, 120 genes passed the quality control and were found to express in 3 gene modules. These modules are mainly related to the regulation of synaptic structure and activity regulation.

CONCLUSIONADHD and LBW share some biological regulation processes. Anomalies of such proces sesmay predispose to ADHD.
