ABSTRACT
Objective@#To explore the relationship between body image and adverse childhood experiences (ACEs) in adolescents.@*Methods@#A total of 1 701 adolescents in grade 6-8 in three middle schools in Shanghai were selected by stratified cluster sampling, and were investigated anonymously using computer assisted self interview approach. Information including demographic characteristics, body image satisfaction, and ACEs were collected. The Chi square test and multivariate Logistic regression were used to explore the relationship between adolescent body image satisfaction and types of ACEs.@*Results@#About 60.73% of the respondents were satisfied with their body image, with higher satisfaction among boys(66.16%) than among girls(55.13%)( χ 2= 21.70 ， P <0.01). About 79.19% of the respondents had experienced at least one ACE, and respectively 61.61%, 65.14% and 21.58 % of them had experienced abuse, neglect and family dysfunction. Multivariate Logistic regression analysis indicated that experiencing at least one ACE, abuse, neglect and family dysfunction were all related with low body image satisfaction among girls( OR =0.33- 0.57 , P <0.01), while among boys neglect,having 3 or more than 4 ACEs were found to be associated with body image satisfaction ( OR =0.54-0.64, P <0.05). The cumulative effects of ACEs on adolescent body image were observed.@*Conclusion@#Different types of ACEs are associated with body image in adolescents, ACEs have cumulative effects on adolescent body image, which shows gender differences.Screen of ACEs and improvement of family nurturing environment should be highlighted among adolescents, especially among girls.

Members of the bZIP transcription factor family play crucial roles in the regulation of plant development, biosynthesis of secondary metabolites, and response to abiotic and biotic stresses. To date, multiple bZIPs have been identified and investigated in numerous plant species. However, few studies have characterized bZIPs from Dimocarpus longan Lour. In this study, nine bZIPs from D. longan were identified from RNA-Seq data and further verified using the NCBI conserved domain search tool and Pfam database. Bioinformatics tools were used to systematically analyse the physicochemical properties, protein structures, multiple sequence alignment, motif compositions, evolutionary relationships, secondary structures, subcellular localization, phosphorylation sites, signal peptides, GO annotations and protein–protein interactions of the DlbZIPs. The expression patterns of the nine DlbZIPs were evaluated by qRT-PCR in roots and leaves and in response to varying durations of a 38C heat treatment. DlbZIP3, DlbZIP5, DlbZIP6 and DlbZIP7 were differentially expressed between root and leaf tissues. All nine DlbZIPs responded to heat treatment in both roots and leaves, but their specific expression levels differed. DlbZIP4 and DlbZIP8 were highly expressed in roots after heat treatment, whereas DlbZIP1 and DlbZIP5 were highly expressed in leaves after heat treatment. These findings lay a foundation for increasing active secondary metabolite content and improving abiotic stress tolerance in D. longan using transgenic technology
ABSTRACT
Objective@#To explore the relationship between different roles in campus bullying and depression among adolescents.@*Methods@#Stratified cluster sampling method was used to select adolescents in grade 6-8 from three middle schools of Shanghai during November and December of 2017. Adolescents were surveyed anonymously using computer assisted self-interview approach via the tablets. Information including demographic characteristics, depression, and bullying was collected. The chi-square test and multivariate Logistic regressions were performed to explore the relationship between bullying roles and depression.@*Results@#About 75.74% of the respondents were involved in bullying, including 456(27.65%) bystanders, 559(33.90%) victims, 33(2.00%) perpetrators, and 201 (12.19%) perpetrator-victims. There were 1 022(61.98%) respondents in the low depression group and 627 (38.02%) in the high depression group. Multivariate logistic regression showed that the four sub-groups involved in bullying all had higher level of depression than those uninvolved, with the perpetrator-victims (OR=4.77, 95%CI=3.27-6.96) and the victims (OR=3.66, 95%CI=2.71-4.94) had more depressive symptoms.@*Conclusion@#Different roles in campus bullying associates with more depressive symptoms, including perpetrators, victims, perpetrator-victims, and the bystanders.
ABSTRACT
Objective@#To explore the relationship between Adverse childhood experiences(ACEs) and depression in early adolescence, and to provide scientific basis for effectively coping with the impact of ACEs on adolescents’ mental health.@*Methods@#Stratified cluster sampling method was used to select adolescents in grade 6-8 in three middle schools of Shanghai during November and December of 2017. Adolescents were investigated anonymously using computer assisted self-interview approach via the tablets. Information including demographic characteristics, ACEs, and depression was collected. The chi-square test and multivariate logistic regression were used to explore the relationship between ACEs and depression, after controlling potential confounders.@*Results@#Totally 1 629 eligible records were obtained. 65.25% of the respondents had experienced of neglect, followed by those abused(61.26%), and the incidence of family dysfunction was relatively low(20.81%). About 79.01% of the respondents had experienced at least one ACE, and more than half(61.45%) of the respondents had experienced at least two ACEs, and 10.01% of the respondents had experienced five or more ACEs. Multivariate logistic regression analysis showed that abuse and neglect experienced by male and female adolescents was associated with depression severity, with the OR values ranging from 2.62 to 3.60. Family dysfunction was found to be associated with depression only in male adolescents, with the OR of 1.91. The cumulative effect of ACE score on depression was observed.@*Conclusion@#Different types of ACEs in early adolescents are associated with depression, and ACEs have cumulative effects on depression severity.
