Background: Childhood trauma has a significant impact on the development of adolescents, which may lead to interpersonal and psychological problems. Determining the incidence and consequences of childhood trauma in psychiatric clinical practice is of great significance. Methods: A survey was conducted among adolescents with mood disorders. Childhood Trauma Questionnaire (CTQ), the Adolescent Non‐Suicidal‐Self‐Injury Behavior Function Assessment Scale (ANBFAS) and a series of psychological scales were filled face to face. Path analysis was used to examine the causation structure of childhood trauma‐related symptoms. Results: A total of 117 participants (74.5%) had experienced at least one type of trauma. Interpersonal and psychological features of adolescent patients with childhood trauma were detailed in this study. The path analysis model showed that the relationships between childhood trauma and NSSI were mediated by depressive symptoms and thinking disorders, respectively, whereas depressive symptoms individually mediated the correlation between childhood trauma and sleep disturbances in adolescent patients with psychiatric disorders (χ2/df = 1.23). Conclusion: For adolescent patients with childhood trauma, psychological counseling for interpersonal relationships should start with families and peers. It is important to treat their depressive symptoms and thinking disorders and alleviate NSSI behavior and sleep disorders. [ABSTRACT FROM AUTHOR]

Highly selective photocatalytic conversion of CO2 into valuable hydrocarbon fuel such as CH4 is a promising solution to tackle greenhouse effect and energy shortage. To achieve this goal, more efforts should be made to design well-performed catalysts. In this work, a series of composite photocatalysts were fabricated for CO2 reduction, through hydrothermal mixing of hydroxylated TiO2 (P25m) with sulfonated covalent porphyrin polymers (s-COP-P). Notably, the optimal sample 2%-s-COP-P/P25m (2% denotes the weight percent of s-COP-P) exhibits the highest production rate (15.5 μmol g−1 h−1) and selectivity (> 90%) of all composites for the formation of CH4 within 1 h, which are nearly 33 and 2 times as large as that of P25m. This good performance was attributed to improved photogenerated carrier separation efficiency verified by enhanced photocurrent and reduced fluorescence intensity that associating closely with the interaction between two moieties of the composites. Based on energy band structure analyses and hydroxyl radical probing, the reduction of CO2 into CH4 was proposed occurring mainly on P25m moiety companied with the oxidation of H2O into hydroxyl radical. In addition, high cyclic stability was confirmed for the composite catalyst by constant photocatalytic performance lasting over four times of cyclic test. This work provides a facile and effective way to design stable photocatalyst for the conversion of CO2 into CH4 in high production rate and selectivity. A sulfonated porphyrin polymer/P25m composite of high cyclic stability was fabricated by simple thermal mixing, and exhibits high photocatalytic activity for the conversion of CO2 into CH4 with a rate of 15.6 μmol g−1 h−1 and a selectivity of > 90%.

Background: Internet is gradually reshaping adolescents' behaviors in China. It is important to identify the prevalence and risk factors to predict Internet addiction among adolescent psychiatric patients. Methods: The survey was conducted among inpatient or outpatient adolescent patients with mental disorders. All participants were interviewed face-to-face and completed Young Internet Addiction Test and other relevant assessments. Binary logistic regression analysis was used to exam between-group differences of internet addiction. Result: The prevalence for internet addiction (mild to severe) in adolescent psychiatric patients was 80.2%, where the prevalence for "medium and severe internet addiction was 25.5%. Logistic regression analysis identified two independent predictors for "medium and severe internet addiction" including the total score of Adolescent Non-suicidal-self-injury (NSSI) Behavior Function Assessment Scale (ANBFAS) and the diagnosis of generalized anxiety disorder (GAD) (R2 =0.27, p =.02 for total ANBFAS score, p =.01 for GAD) in psychiatric adolescent patients. Conclusion: The prevalence of internet addiction is notably high among adolescent psychiatric patients in China. Coping for Internet addiction in adolescent psychiatric patients should conclude the coping of NSSI and GAD. [ABSTRACT FROM AUTHOR]

Threedifferent methods were used to prepare CuY catalysts, whichplay an important role in Cu loading and ion-exchange level duringthe oxidative carbonylation of ethanol to synthesize diethyl carbonate.Of the prepared CuY catalysts, those synthesized by the ammonia evaporationmethod exhibited a significantly enhanced activity compared to thoseobtained by the other two methods. In addition, under optimized conditions,four different copper precursors were applied to adjust the texturalproperties and chemical states of the CuY catalysts. To obtain a deepunderstanding of their structure–performance relationship,XRD, XPS, CO adsorption, DRIFTS, and NH3TPD were conductedto characterize the CuY catalysts. The experimental results indicatedthat the catalytic performances were in line with the proportionsof Cu+in CuY catalysts, which can be regulated by cupricprecursors. In addition, the textural structures of the catalystsand the acidity and type of Cu+species influenced by theprecursors were all responsible for the activity and product distribution.

Background: Non-suicidal self-injury (NSSI) has attracted more and more attention from schools, mental health workers and even the whole society in China. The aim of this study was to explore influencing factors and clinical characteristics of NSSI in adolescent psychiatric patients in China, and provide valuable information for the intervention and treatment of NSSI., Methods: The sample included 157 adolescents, 114 were female (72.6%), aged 12-18 years ( M = 15.39, SD = 1.81). Assessments were performed using Childhood Trauma Questionnaire-Short Form, the Revised Olweus Bully/Victim Questionnaire, the modified version of Adolescents Self-Harm Scale, Montgomery-Asberg Depression Rating Scale, Brief Psychiatric Rating Scale, the Young Mania Rating Scale and the Mini International Neuropsychiatric Interview. Clinical characteristics were collected from electronic medical record system., Results: Adolescent patients with NSSI experienced more adverse life events including peer bullying, childhood trauma and romantic relationship trouble. They had more times of hospitalization, higher dosage of psychotic medication, and more severe depressive symptoms., Conclusions: It is very necessary to evaluate negative life events, including childhood trauma, peer bullying etc., in adolescent patients with NSSI. It has important clinical implications for evaluating the risk factors of NSSI and giving effective intervention treatment. Timely and effective treatment of these patients' depressive symptoms will also contribute to the relief of NSSI., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Zhang, Liu, Zhang, Huang, Wang, Yang, Wang, Jia and Hou.)
