EEG biomarkers of behavioral inhibition in patients with depression who committed violent offenses: a Go/NoGo ERP study.

Understanding the neurobiological correlates of behavioral inhibition in patients with depression who committed violent offenses could contribute to the prediction and prevention of violence. The present study recruited 29 depressed patients with violent offenses (VD group), 27 depressed patients without violent behavior (NVD group), and 28 healthy controls (HC group) to complete a visual Go/NoGo task, during which their responses and electroencephalography were simultaneously recorded using an event-related potentiometer. The results showed that the VD group made more commission errors and responded more slowly relative to the NVD and HC groups.

Neurological Symptoms and Their Associations With Inflammatory Biomarkers in the Chronic Phase Following Traumatic Brain Injuries.

Background: The underlying biological mechanisms for neurological symptoms following a traumatic brain injury (TBI) remain poorly understood. This study investigated the associations between serum inflammatory biomarkers and neurological symptoms in the chronic phase following moderate to severe TBI.

Methods: The serum interleukin [IL]-1β, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12p70, and the tumor necrosis factor [TNF]-α in 72 TBI patients 6 months to 2 years post injury were measured.

Migration, Schizophrenia, and Crime: A Study From a Forensic Psychiatric Sample.

Background: The association between mental health problems and crime in immigrants has attracted recent academic interest, with results suggesting that there were possible interactions between immigration, schizophrenia, and criminal behavior. However, very few studies have examined these interactions, especially in developing countries that have mass internal immigration. Therefore, this study sought to identify the associations between the sociodemographic, clinical, and criminal factors in migrants and non-migrants with schizophrenia who had been involved in criminal activities in China.

Enhancement of the Thermoelectric Performance of CuGeSe via Isoelectronic (Ag, S)-co-substitution.

Recently, ternary Cu-based Cu-IV-Se (IV = Sb, Ge, and Sn) compounds have received extensive attention in the thermoelectric field. Compared with Cu-Sb-Se and Cu-Sn-Se, Cu-Ge-Se compounds have been less studied due to its poor Seebeck coefficient and high thermal conductivity. Here, the CuGeSe material with high electrical conductivity was first prepared, and then, its effective mass was increased by doping with S, which led to the Seebeck coefficient of the doped sample being 1.

Research on interpersonal violence in schizophrenia: based on different victim types.

Background: Schizophrenia is one of the most common severe mental disorders associated with an increased risk of violence. The present study compares the demographical, clinical, and criminological characteristics of the patients with schizophrenia who committed different types of violence to relatives, acquaintances, or strangers.

Method: Archives of the violent offenders with schizophrenia referred to forensic psychiatric assessments from January 2015 to December 2019 in the West China Forensic Medicine Assessment Center in China were analyzed.

Remarkable photoluminescence of europium(ii)-doped phosphate cyan@red-emitting phosphors with highly dispersed luminescence centers.

Europium(ii)-doped phosphate cyan@red-emitting phosphors with highly dispersed luminescence centers were developed for the first time by using the deposition-precipitation method. Amazingly, when excited by near-ultraviolet light, the single phosphor generated warm white light with an adjustable correlated colour temperature (4000-2500 K) and high colour-rendering index (Ra ∼ 90).

Comparative study of forensic psychiatric system between China and America.

Laws and regulations about the forensic psychiatric systems in China and America were compared, and suggestions for improving the forensic psychiatric system of China were provided. There are many differences regarding the role of the forensic psychiatrist, the initiation of the assessment and the admission of expert opinion because of elements in the legal systems in China and America. The Chinese system has the advantages of objectivity, cost saving and high efficiency; but it has deficiencies in procedural justice and the admission of expert opinion.

Genetic variants in the promoters of let-7 family are associated with an increased risk of major depressive disorder.

Background: Let-7 family plays a critical role in the pathogenesis of major depressive disorder (MDD). Genetic polymorphisms in the promoters of miRNA may influence individual׳s susceptibility to diseases. The purpose of this study was to investigate the association between rs10877887 and rs13293512 polymorphisms in the promoters of let-7 family and the risk of MDD.

Accuracy rate of lie-detection in China: estimate the validity of CQT on field cases.

Objective: To explore the accuracy rate of the comparison question test (CQT) by Binomial Distribution way on field cases in Chengdu area of China. In detail, the study revealed the accuracy rate of detecting guilty and innocent examinees, and the rate of False Positive and False Negative.

Method: The study was built on the field cases with only two examinees that held the opposite opinions to the same single case.

An exploratory study of using polygraph to detect deception in patients with traumatic brain injury.

To investigate the accuracy of the polygraph when used on patients with traumatic brain injury (TBI) and to analyze the factors influencing accuracy to enable provision of some field data for expert witnesses. Sixty patients with TBI (experimental group) and sixty normal individuals (control group) were tested by the polygraph with a Stimulation Test; responses of skin conductance, respiration, and finger pulse were recorded. The intelligence quotient of the experimental participants was measured and the factors influencing the accuracy of the polygraph test were analyzed.

Lack of association between brain-derived neurotrophic factor Val66Met polymorphism and aggressive behavior in schizophrenia.

We investigated the association of the Val66Met gene polymorphism in the Brain-Derived Neurotrophic Factor (BDNF) gene with aggressive behavior among Southern Han Chinese schizophrenia patients. We used polymerase chain reaction-restriction fragment length polymorphism to determine the genotypes and the Modified Overt Aggression Scale (MOAS) to measure aggressive behavior. No significant differences in genotype or allele distribution of Val66Met were identified between aggressive and non-aggressive schizophrenia patients.

Association between COMT gene and Chinese male schizophrenic patients with violent behavior.

Background: Haplotype analysis is hypothesized as having better power than individual SNPs in detecting the association between genotype and phenotype, but this approach has rarely been used in studies of the genetics of violent behavior in schizophrenia. The aim of this study was to further examine the role of the COMT gene in violent behavior.

Material/methods: Both individual SNP and haplotype were used to explore associations between COMT polymorphisms and violent behavior in 252 patients with violent behavior and 332 patients without violent behavior of Chinese Han schizophrenics.

RTMS may be a good choice for pregnant women with depression.

Due to the possible adverse effects on fetus, the treatment of pregnant women with depression is a difficult problem in the field of psychiatry. Repetitive transcranial magnetic stimulation (rTMS) was used to treat three pregnant women with depression in the early pregnancy. After systemic treatments, the patient's depressive symptoms significantly relieved, and each of them smoothly provided a healthy baby.

[A study on characteristics of the criminals with alcohol-related offence in forensic psychiatry].

Objective: To explore the criminal characteristics of alcohol-related offence in forensic psychiatric practice.

Methods: Ninety cases were collected according to our research criteria and were divided into two groups, ordinary drinking (OD) (63 cases) and chronic alcoholic (CA) (27 cases). Descriptive and comparative studies were conducted between the two groups.

[The criminological characteristics of mental retardation].

Objective: To explore the criminological characteristics of mental retardation (MR) in forensic psychiatry.

Methods: The record scale of forensic psychiatric assessment designed by ourselves was used to analyse the criminological characteristics of 83 offenders with MR, and to compare the criminological characteristics of mild MR with that of moderate and severe MR.

Results: The mild MR accounted for 62.
