Analysis of correlation between childhood abuse and adolescent psychological capital / 中国学校卫生

Objective@#To understand current situation and relations of childhood abuse and psychological capital, providing scientific basis for adolescent mental health promotion.@*Methods@#Stratified cluster sampling method was used to select 1 894 students from junior high schools and senior high schools in Harbin. Questionnaire survey was conducted by using Childhood Trauma QuestionnaireShort Form (CTQ-SF) and Positive Psychological Capital (PPQ).@*Results@#The total rate of childhood abuse among adolescents in the region was 98.3%. In addition to emotional abuse, scores of other dimensions of childhood abuse were higher for boys than for girls(P<0.01). Childhood abuse in rural area was higher than those in urban area except physical abuse(P<0.05). High psychological capital was observed among participants with boys higher in selfefficacy and resilience than that of girls(P<0.05). Psychological capital in urban students was higher than rural students(P<0.05). Except for the negative correlation between sexual abuse and resilience, all other dimensions of childhood abuse were negatively correlated with four dimensions of psychological capital. Stepwise regression analysis showed that emotional abuse, emotional neglect and physical neglect was negatively correlated with all dimensions of psychological capital(P<0.01); Sexual abuse showed negative association with selfefficacy and optimism(P<0.01).@*Conclusion@#Childhood abuse is closely related to psychological capital among adolescents in Harbin, suggesting exposure to childhood abuse might confer detrimental effects on psychological capital development.

GATA3-IL-13 pathway gene polymorphisms are associated with serum IL-13 and asthma / 中国免疫学杂志

Objective:Asthma is a chronic inflammatory respiratory disease .The data show that involvement of the GATA 3-IL-13 gene in asthma is biologically plausible .The objective of this study is investigated the association of GATA 3-IL13 gene polymorphisms and IL-13 levels with asthma;assess the correlations between GATA 3-IL-13 gene SNPs polymorphisms and serum levels of IL-13 in population of Xinjiang (China).Methods:A case group of 279 patients and 277 healthy controls were genotyped to perform using the MassARRAY SNP genotyping system.In 279 asthma patients and 277 controls,IL-13 levels were measured by ELISA.Data were analyzed using the statistical package for social science (SPSS) 22.0 (IBM,NY,USA) and Graph Pad Prism 6.0.Results:Patients were found that IL-13 levels were associated with asthma in asthmatic and the IL-13 ( rs2066960 AA ) , GATA3 ( rs3781093 CC) genotype was associated with a notably increased risk of asthma compared with the CC (rs2066960),TT (rs3781093) genotype (P<0.05).Similarly,IL-13(rs2066960) C-A alleles were significantly associated with risk of asthma (P<0.05).However,the rs3781093 C-T alleles had no obvious differences (P>0.05).In addition,the patients carrying the rs2066960 AA genotype presented with higher IL-13 levels compared to the CC group .Conclusion:This result suggests that the rs 2066960 C-A variant is associated with IL-33 levels in patients with asthma .
