Objective: To examine the mediating role of empathy and emotional competence in the association between family functioning and internalizing and externalizing problem behaviors among adolescents in China. Methods: In this study, we used the data from the June-July 2022 survey of Chengdu Positive Child Development (CPCD) cohort. All respondents were 5th-9th graders from six primary or secondary schools in Chengdu. The Achenbach Child Behavior Checklist (CBCL), the Chinese Family Assessment Instrument (C-FAI), the empathy subscale of the Chinese version of the Interpersonal Reactivity Index (C-IRI), and the emotional competence (EC) subscale of the Chinese Positive Youth Development Scale (CPYD) were used to evaluate the respondents' internalizing and externalizing problem behaviors, family functioning, empathy, and emotional competence, respectively. The average score derived from the total score of a scale divided by the number of entries in each dimension was used as the final score of the scale. Independent samples t-tests or one-way analysis of variance (ANOVA) were performed to examine the differences in family functioning, empathy, emotional competence, and internalizing and externalizing problem behaviors across student groups with different demographic characteristics (sex, grade, and region). Pearson correlation analysis was conducted to examine the relationship between family functioning, empathy, emotional competence, and internalizing and externalizing problem behaviors. AMOS 24.0 was used to validate the hypothesized model and structural equation modeling was used to analyze the mediating effects of empathy and emotional competence between family functioning and internalizing and externalizing problem behaviors among adolescents. Results: A total of 3026 eligible participants were included, including 1548 (51.16%) male students and 1478 (48.84%) female students. Among the respondents, 798 (26.37%) were 5th graders, 738 (24.39%) were 6th graders, 567 (18.74%) were 7th graders, 614 (20.29%) were 8th graders, and 309 (10.21%) were 9th graders. In addition, 2064 (68.21%) of all respondents were from urban areas and 962 (31.79%) were from rural areas. The results of the difference analysis showed that the differences in adolescents' internalizing and externalizing problem behaviors were statistically significant between students of different grades (P=0.004), and that the differences in family functioning and empathy scores were also statistically significant between students of different grades (all P<0.001), whereas the differences in adolescents' internalizing and externalizing problem behaviors were not statistically significant between sexes and regions (P=0.919, 0.959). The results of correlation analysis showed that family functioning scores (the higher the score, the worse the family functioning) were significantly negatively correlated with empathy and emotional competence (r=-0.482, -0.432, P<0.01), and significantly positively correlated with internalizing and externalizing problem behaviors (r=0.220, P<0.01). Empathy was significantly positively correlated with emotional competence (r=0.402, P<0.01). Empathy and emotional competence were significantly negatively correlated with all the dimensions of internalizing and externalizing problem behaviors (r=-0.115, -0.305, P<0.01). Emotional competence partially mediated the relationship between family functioning and adolescents' internalizing and externalizing problem behaviors, with a mediation effect value being 0.042 (95% [confidence interval] CI: 0.031-0.057). Empathy and emotional competence had chain mediation effect between family functioning and adolescents' internalizing and externalizing problem behaviors, with the value of the mediation effect being 0.010 (95% CI: 0.007-0.014). Conclusion: Family functioning influences adolescents' internalizing and externalizing problem behaviors in a direct way and through the chain-mediating roles of empathy and emotional competence.

Clinical utility and effectiveness of a training programme in the application of a new classification of narrow-band imaging for vocal cord leukoplakia: A multicentre study.

OBJECTIVE: To analyse the application of a new narrow-band imaging (NBI) classification in the diagnosis of vocal cord leukoplakia by laryngologists with different levels of laryngoscopic experience and to explore the impact of NBI training programmes on laryngologists' identification of benign and malignant leukoplakia. DESIGN: Prospective multicentre study. SETTING: Tertiary hospitals. PARTICIPANTS: Sixteen laryngologists were divided into less-experienced and experienced groups and received NBI training course. Thirty cases of vocal cord leukoplakia were investigated. MAIN OUTCOME MEASURES: Diagnostic accuracy and interobserver agreement under white light imaging (WLI), before and after NBI training, were analysed among doctors with varying levels of experience. RESULTS: The accuracy in the less-experienced group was significantly lower than that of experience group (0.59 vs 0.69) under WLI. There was no significant difference in the diagnostic accuracy between the less-experienced group and the experienced group before NBI training (0.75 vs 0.74) and after NBI training (0.79 vs 0.83). NBI training could improve the interobserver agreement from fair or moderate to good agreement. CONCLUSION: The new NBI diagnostic classification is helpful for identifying benign and malignant vocal cord leukoplakia. In addition, the NBI training programme can improve the diagnostic accuracy and interobserver agreement of less-experienced doctors to the level of experienced laryngologists.

The Effect of Mental Health Status and Family Function on Nonsuicidal Self-Injury: A Longitudinal Analysis of Chinese Children and Adolescents.

Background: Nonsuicidal self-injury (NSSI) is an overwhelming social problem in children and adolescents. Focusing on the change of NSSI behavior, including onset, cessation, and maintenance, is crucial to developing effective prevention and intervention strategies. This study explored the effect of mental health status (depressive and anxiety symptoms) and family function on NSSI. Methods: The study sample comprised 7554 children and adolescents based on the first two rounds of the Chengdu Positive Child Development (CPCD) dataset in China. Depressive and anxiety symptoms measured mental health status. The self-reported questionnaires also assessed NSSI behaviors and family function. The interrelationship between NSSI behaviors, mental health status, and family function was evaluated. Logistic regression and linear regression were performed to examine the interrelationship between mental health status, family function and NSSI behaviors. Sensitivity analysis was performed. Results: In this study, 2167 (28.69%) participants reported NSSI at baseline and 2101 (27.81%) at follow-up. Depression, anxiety, and family function were salient influential factors in the prevalence, onset, and cessation of NSSI. Parents' accompaniment showed a significant effect on the prevalence of NSSI. Conclusion: Depression, anxiety, family function, and parents' accompaniment are all associated with NSSI behaviors. Strategies targeting mental health status and family function could effectively protect children and adolescents from NSSI behaviors.

GJB2, SLC26A4, and mitochondrial DNA12S rRNA hot-spots in 156 subjects with non-syndromic hearing loss in Tengzhou, China.

CONCLUSION: In this cohort of 156 non-syndromic hearing-impaired subjects of Tengzhou area, the most common deafness-associated genes GJB2, SLC26A4 and mtDNA 12S rRNA were investigated by SNPscan efficiently. GJB2 c.235delC and SLC26A4 c.IVS7-2A > G were the most common mutation sites. OBJECTIVES: Until now, there is no systematic gentic analysis in patients with non-syndromic hearing loss for Tengzhou area, so we evaluated the molecular etiology to investigate the hot-sports. METHODS: Peripheral blood samples were obtained from 156 patients with severe-to-profound non-syndromic deafness in Tengzhou. The SNP scan assay technique was performed for a rapid multiplex genetic screening to detect the 115 mutations of the most common three genes. All results were statistically analyzed with SPSS software. RESULTS: Among the 156 analyzed patients, 60 patients were demonstrated with deafness genes, accounting for 38.46% (60/156), including GJB2 (22.44%, 35/156), SLC26A4 (13.66%, 22/156), and mtDNA 12S rRNA (2.56%, 4/156). In this study, we confirmed 23 deafness-causing mutations and 27 different allelic combinations including GJB2 (eight variants, 11 allelic combinations), SLC26A4 (13 variants, 16 allelic combinations) and mtDNA 12S rRNA (two variants). The occurrence rates of these deafness-causing mutations GJB2 c.235delC and SLC26A4 c.IVS7-2A > G were significantly higher than other mutation sites (p < 0.01).

[Possibility probe on glucocorticoid treating primary child epistaxis].

OBJECTIVE: To probe the curative effect of glucocorticoid (GCD) on primary child epistaxis (PCE). METHOD: (1) Make rabbit model with nasal allergic reaction and nasal septum mucosa erosion, by dropping nose with toluene diisocyanate then curettaging front-middle-part of nasal septum mucosa. Divide them into two groups dexamethasone group and antibiotics group. (2) Questioning investigate the relationship between PCE and nasal allergic reaction to 1000 school children. (3) Two hundred cases of nasal bleeding children were divided into two groups dexamethasone-therapy-group and control-group. RESULT: (1) The healing period of rabbit nasal septum mucosa is much shorter in dexamethasone group than in another group. (2) The genesis rate of school-children nasal bleeding is significantly higher in those with allergic rhinitis than in those without it. (3) The curative effect of therapy-group is much higher than that of control-group, there is significant difference. CONCLUSION: There is close relationship between PCE and nasal allergic reaction. Nasal allergic reaction is one of the most important reasons for child epistaxis. Through inhibiting the allergic reaction, GCD can promote the erosive nasal septum mucosa healing. GCD has great curative effect on PCE.
