Exploring Association Between Serotonin and Neurogenesis Related Genes in Obsessive-Compulsive Disorder in Chinese Han People: Promising Association Between DMRT2, miR-30a-5p, and Early-Onset Patients.

Obsessive-compulsive disorder (OCD) is a deliberating disorder with complex genetic and environmental etiologies. Hypotheses about OCD mainly include dysregulated neurotransmitters, especially serotonin, and disturbed neurodevelopment. Single nucleotide polymorphism (SNP) association studies regarding OCD are often met with inconsistent results.

Changing patterns and influencing factors of involuntary admissions following the implementation of China's mental health law: A 4-year longitudinal investigation.

Involuntary admission (IA) is limited to particular situations in mental health laws to protect patients from unnecessary coercion. China's first national mental health law has been in effect since 2013; however, the status of IA has not been sufficiently explored. To explore the changing patterns of IA since the clinical application of the IA criteria specified in the new law, an investigation of IA status was undertaken in 14 periods (each period lasting for one month from 05/2013 to 05/2017) in the tertiary specialized psychiatric hospital in Shanghai.

The classification of eating disorders in China: A categorical model or a dimensional model.

Objective: According to the ICD-10 and DSM-5, eating disorders (EDs) are classified using a categorical model that assumes the subtypes are qualitatively different from one another. However, it is still intensely debated that a dimensional model is more suitable. The aim of this study is to examine whether EDs have a categorical or dimensional latent structure using a sample of Chinese ED patients.

Cortical surface area reduction in identification of subjects at high risk for post-traumatic stress disorder: A pilot study.

Objective: Victims of motor vehicle accidents often develop post-traumatic stress disorder, which causes significant social function loss. For the difficulty in treating post-traumatic stress disorder, identification of subjects at high risk for post-traumatic stress disorder is essential for providing possible intervention. This paper aims to examine the cortical structural traits related to susceptibility to post-traumatic stress disorder.

Psychometric Properties of the Chinese Version of the Eating Attitudes Test in Young Female Patients with Eating Disorders in Mainland China.

The study aimed to investigate the reliability and validity of the Chinese version of the eating attitudes test (EAT-26) among female adolescents and young adults in Mainland China. This scale was administered to 396 female eating disorder patients and 406 noneating disorder healthy controls, in addition 35 healthy controls completed a retest after a 4-week intervals. Tests for reliability, convergent validity and receiver operating characteristic analysis were performed to detect the psychometric properties.

A compromise solution between overlapping and overlooking DSM personality disorders in Chinese psychiatric practice.

Objective: This study aimed to examine the overlaps between the Diagnostic and Statistical Manual-5 (DSM-5) Personality Disorders (PDs) in a high-risk clinical population and to explore a transitional model for implementing DSM-5 PDs.

Peripheral SLC6A4 Gene Expression in Obsessive-Compulsive Disorder in the Han Chinese Population.

Background: Serotonergic system dysfunction has been implicated in obsessive-compulsive disorder (OCD). This study examined peripheral SLC6A4 gene expression in OCD patients and healthy controls to explore the relationship between SLC6A4 and OCD.

Methods: Participants included 50 first episode OCD patients and 60 age and gender-matched healthy controls.

Progressive decline of cognition during the conversion from prodrome to psychosis with a characteristic pattern of the theory of mind compensated by neurocognition.

The association between neurocognition and the theory of mind (ToM) abilities during the progression of psychosis is unclear. This study included 83 individuals with attenuated psychosis syndrome (APS), from which 26 converted to psychosis (converters) after a follow up period of 18months. Comprehensive cognitive tests (including MATRICS Consensus Cognitive Battery, Faux-Pas Task, and Reading-Mind-in-Eyes Tasks) were administered at baseline.

Divergent Structural Responses to Pharmacological Interventions in Orbitofronto-Striato-Thalamic and Premotor Circuits in Obsessive-Compulsive Disorder.

Prior efforts to dissect etiological and pharmacological modulations in brain morphology in obsessive-compulsive disorder (OCD) are often undermined by methodological and sampling constraints, yielding conflicting conclusions and no reliable neuromarkers. Here we evaluated alteration of regional gray matter volume including effect size (Cohen's d value) in 95 drug-naïve patients (age range: 18-55) compared to 95 healthy subjects (age: 18-63), then examined pharmacological effects in 65 medicated (age: 18-57) and 73 medication-free patients (age: 18-61). Robustness of statistical outcomes and effect sizes was rigorously tested with Monte Carlo cross-validation.

Association of the 5-HT receptor gene promoter polymorphism-1438G/A with anorexia nervosa and psychopathological traits in the Chinese Han population: A preliminary study.

Objective: The aim of the study was to explore the possible role of the 5-HT -1438G/A polymorphism in the susceptibility to anorexia nervosa (AN) in the Chinese Han population.

Methods: The -1438G/A polymorphism of 249 female AN patients, 228 matched healthy controls, and 198 trios was genotyped using SNaP shot assay. Psychopathological traits of eating-disordered behaviors in AN subjects were examined using the Chinese version of the Eating Disorder Examination Questionnaire.

Brain Gamma-Aminobutyric Acid (GABA) Concentration of the Prefrontal Lobe in Unmedicated Patients with Obsessive-Compulsive Disorder: A Research of Magnetic Resonance Spectroscopy.

Background: In recent years, a large number of neuroimaging studies found that the Cortico-Striato- Thalamo-Cortical circuit (CSTC), including the prefrontal lobe, a significant part of CSTC, has disturbance metabolically in patients with Obsessive-Compulsive Disorder (OCD).

Aim: Explore the correlation between the neuro-metabolic features and clinical characteristics of OCD patients using magnetic resonance spectroscopy technology.

Methods: 88 patients with OCD who were not received medication and outpatient treatment for 8 weeks and 76 health controls were enrolled, there was no significant difference in gender, age or education level between the two groups.

Intrinsic functional connectivity alteration of dorsal and rostral anterior cingulate cortex in obsessive-compulsive disorder: A resting fMRI study.

Cortico-striato-thalamo-cortical (CSTC) circuit has been implicated in OCD pathophysiology by converging neuroimaging findings. The anterior cingulate cortex (ACC), as an important part within CSTC circuit, plays a critical role in OCD etiology. The ACC can be divided into dorsal and rostral parts anatomically, which are involved in cognitive process and emotional function, respectively.

Using 'WeChat' online social networking in a real-world needs analysis of family members of youths at clinical high risk of psychosis.

Objective: The argument surrounding the safety and effectiveness of interventions for the population of individuals at a clinical high risk of developing psychosis has been ongoing for the past 30 years. However, few studies have assessed the needs of this special young population, who are struggling with the recent onset of psychotic symptoms.

Method: The sample consisted of 171 family members of 108 clinical high-risk individuals included from the ShangHai at Risk for Psychosis research programme.

Resting-state functional connectivity changes within the default mode network and the salience network after antipsychotic treatment in early-phase schizophrenia.

Objective: Abnormal resting-state functional connectivity (FC), particularly in the default mode network (DMN) and the salience network (SN), has been reported in schizophrenia, but little is known about the effects of antipsychotics on these networks. The purpose of this study was to examine the effects of atypical antipsychotics on DMN and SN and the relationship between these effects and symptom improvement in patients with schizophrenia.

Methods: This was a prospective study of 33 patients diagnosed with schizophrenia and treated with antipsychotics at Shanghai Mental Health Center.

Correlation of social cognition and neurocognition on psychotic outcome: a naturalistic follow-up study of subjects with attenuated psychosis syndrome.

Neurocognitive decline has been observed in patients with psychosis as well as attenuated psychosis syndrome (APS). We tested the hypothesis that APS increases dependence on neurocognition during the interpretation of others' mental states and that a combination index of Theory of Mind (ToM) and neurocognition improves the predictive accuracy of psychosis conversion. A sample of 83 APS individuals and 90 healthy controls (HC) were assessed by comprehensive cognitive tests.

Co-morbidity of personality disorder in schizophrenia among psychiatric outpatients in China: data from epidemiologic survey in a clinical population.

Background: The reported rates of personality disorder (PD) in subjects with schizophrenia (SZ) are quite varied across different countries, and less is known about the heterogeneity of PD among subjects with SZ. We examined the co-morbidity of PD among patients who are in the stable phase of SZ.

Method: 850 subjects were randomly sampled from patients diagnosed with SZ in psychiatric and psycho-counseling clinics at Shanghai Mental Health Center.

Theory of Mind Impairments in Youth at Clinical High Risk of Psychosis.

Objective: The normal maturational processes of theory of mind (ToM) capacity are ongoing during adolescence and even early adulthood. However, research has shown that ToM ability also declines among adults suffering from prodromal psychotic experiences. The goal of this study was to investigate the characteristics of ToM performance in youth with clinical high risk (CHR) of psychosis.

Dopamine receptor D2 and catechol-O-methyltransferase gene polymorphisms associated with anorexia nervosa in Chinese Han population: DRD2 and COMT gene polymorphisms were associated with AN.

Dopamine receptor D2 (DRD2) and catechol-O-methyltransferase (COMT) are important in dopamine system which is proved to be associated with food-anticipatory behavior, food restriction, reward and motivation. This has made them good candidates for anorexia nervosa (AN). The aim of this work is to explore the roles of DRD2 (rs1800497) and COMT (rs4680, rs4633, rs4818) gene polymorphisms in the susceptibility of AN within the Chinese Han population.
