USP22 controls iNKT immunity through MED1 suppression of histone H2A monoubiquitination.

The ubiquitin pathway has been shown to regulate iNKT cell immunity, but the deubiquitinase involved in this process has not been identified. Herein we found that ubiquitin-specific peptidase 22 (USP22) is highly expressed in iNKT cells during their early developmental stage 1. USP22 deficiency blocked the transition from stage 1 to 2 during iNKT cell development in a cell-intrinsic manner.

Background: Depression in HIV/AIDS children not only worsens the progression and outcome of illness, but also impacts their quality of life, having a negative influence on society. The present study was conducted from a psychosocial perspective, considering children's social desirability, cognitive emotion regulation, and perceived social support to identify the factors influencing depression in HIV-infected children in China.

Methods: Participants were 155 children aged 8-18 years who were eligible to participate in this study assessing depression and associated risk factors using the Children's Depression Inventory, Cognitive Emotion Regulation Questionnaire, Multidimensional Scale of Perceived Social Support, and Children's Social Desirability scale.

Randomized controlled trial of cognitive behavioural therapy for depressive and anxiety symptoms in Chinese women with breast cancer.

Depressive and anxiety symptoms are frequently observed in breast cancer survivors. To date, few randomized controlled trials have been conducted on the efficacy of cognitive behavioural therapy (CBT) for depressive and anxiety symptoms in Chinese population. This study aims to verify the efficacy of CBT in Chinese breast cancer survivors.

Purpose: Cognitive behavioral therapy (CBT) for depression had been found to be effective in reducing depressive and anxiety symptoms in breast cancer survivors. It is not known whether CBT for depression would also improve insomnia and quality of life (QOL). The aim of this study was to investigate whether CBT for depression would improve insomnia and QOL in a randomized controlled multicenter trial.

Dvl3 polymorphism interacts with life events and pro-inflammatory cytokines to influence major depressive disorder susceptibility.

The purpose of this study is to explore Dvl3 variants and their interaction with negative life events on MDD susceptibility in a Chinese Han population. Additionally, we also attempted to identify whether there is an association between Dvl3 variants and pro-inflammatory cytokines. A total of 1102 participants, consisting of 550 patients with MDD and 552 healthy subjects, were recruited for genotyping by TaqMan allelic discrimination assay.

ER-associated ubiquitin ligase HRD1 programs liver metabolism by targeting multiple metabolic enzymes.

The HMG-CoA reductase degradation protein 1 (HRD1) has been identified as a key enzyme for endoplasmic reticulum-associated degradation of misfolded proteins, but its organ-specific physiological functions remain largely undefined. Here we show that mice with HRD1 deletion specifically in the liver display increased energy expenditure and are resistant to HFD-induced obesity and liver steatosis and insulin resistance. Proteomic analysis identifies a HRD1 interactome, a large portion of which includes metabolic regulators.

The purpose of the current study was to investigate how post-surgery multifaceted body image predicts negative affect (NA) 6 months post-surgery among women undergoing mastectomy. In total, 310 Chinese women undergoing mastectomy were recruited from a hospital in the Hunan province between 2012 and 2013. Upon enrollment (T1), all women were administered the Chinese version of Body Image after Breast Cancer Questionnaire (BIBCQ) (BIBCQ-C), NA subscale of Positive and Negative Affect Schedule (PANAS), Multidimensional Scale of Perceived Social Support (MSPSS), Hamilton Anxiety Scale (HAMA), and Hamilton Depression Scale (HAMD).

Serial multiple mediation of organizational commitment and job burnout in the relationship between psychological capital and anxiety in Chinese female nurses: A cross-sectional questionnaire survey.

Background: Nurses play an important role in medical and health services but anxiety among those in this profession is widespread. Anxiety not only damages the physical and mental health of the individual, but also reduces the efficiency of their work and the quality of care, ultimately impacting on patient care. Therefore, it is necessary to elucidate the factors that lead to anxiety and explore measures to reduce the impact these factors have on nurses.

Meta-analysis of the interaction between serotonin transporter promoter variant, stress, and posttraumatic stress disorder.

Exposure to stress predicts the occurrence of posttraumatic stress disorder (PTSD) in individuals harboring the serotonin transporter promoter variant 5-HTTLPR. We carried out a meta-analysis of studies investigating the interaction between 5-HTTLPR, stress, and PTSD to clarify the interrelatedness of these factors. We reviewed all relevant studies published in English before May 2016.

Mismatch negativity as a potential neurobiological marker of early-stage Alzheimer disease and vascular dementia.

Alzheimer's disease (AD) and vascular dementia (VD) are serious, irreversible forms of cognitive impairment, which means that an early diagnosis is essential to slow down their progression. One potential neurophysiological biomarker of these diseases is the mismatch negativity (MMN) event-related potentials (ERP) component, which reflects an automatic detection mechanism at the pre-attentive stages of information processing. We evaluated the auditory MMN response in individuals from two patient groups: those in the prodromal stages of AD (P-AD) and those in the prodromal stages of VD (P-VD).

GNB3 and CREB1 gene polymorphisms combined with negative life events increase susceptibility to major depression in a Chinese Han population.
