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.

Objective To investigate the effect of empathy on depressive symptoms in adolescents and to explore the potential mediating role of family functioning in the effect of empathy on depressive symptoms.Methods The 2022 cross-sectional data from the Chengdu Positive Child Development(CPCD)cohort were analyzed in the study.A survey was conducted in Chengdu in June 2022,involving 3 020 students in grades 5-8 from three randomly selected stratified schools.The Interpersonal Reactivity Index(IRI-C),the Chinese Family Assessment Instrument(C-FAI),and the Center for Epidemiologic Studies Depression Scale for Children(CES-DC)were used in the survey.Chi-square test or one-way analysis of variance was performed to examine the differences in various demographic characteristics(sex,grade,region,and total monthly household income)between groups of respondents,as well as the differences in family functioning,empathy,and depression.Pearson correlation coefficient was used to examine the correlation between family functioning,empathy,and depressive symptoms.Structural equation modeling and SPSS PROCESS component Model 4 were used to analyze whether family functioning played a mediating role in the effect of empathy on depressive symptoms in adolescents.Results The detection rate of depressive symptoms among survey respondents was 25.40%.The results of the difference analysis revealed significant differences in the detection rates of depressive symptoms among respondents of different grades,regions,and monthly household incomes(P<0.05).There was no significant difference in the detection rates of depressive symptoms between male and female students.There was a significant difference in the detection rate of depressive symptoms between respondents with different scores for family dysfunction and empathy ability(P<0.001).Correlation analysis results showed that empathy scores were negatively correlated with depression(r=-0.11,P<0.001),that family dysfunction was positively correlated with depression(r=0.29,P<0.001),and that empathy scores were negatively correlated with family functioning(r=-0.37,P<0.001).The mediating role of family dysfunction in the relationship between empathy and depressive symptoms was established,with the direct effect being 0.039(95% confidence interval[CI]:0.010-0.069,P<0.001)and the indirect effect value being-0.096(95% CI:-0.115--0.079,P<0.001).The direct effect value accounted for 28.89% of the total effect value,while the mediation effect value accounted for 71.11% of the total effect value.Conclusion The empathy ability of adolescents is correlated to depressive symptoms,and family functioning plays a mediating role between empathy and depressive symptoms in adolescents.It is suggested that adolescents'empathy ability and family functioning should be enhanced through multiple channels to reduce the occurrence of depressive symptoms.

OBJECTIVE To investigate predisposing factors of candidemia in nosocomial infections.METHODS To retrospectively review the clinical features of 120 cases,including 59 who developed candidemia and 61 cases with bacteremia during the period of 1990-2004.RESULTS The incidence of candidemia was stable over a 14-year period.Candida albicans remained the predominant Candida species recovered(30.5%),followed by C.tropicalis(25.7%),C.glabrata(12.9%),C.parapsilosis(12.9%) and others(17.1%).Of the total 59 cases of candidemia,were administrated by broad spectrum antibiotic therapy for long time,urinary catheters,malignant tumor,etc.Multivariate analysis showed that candidemia was related with many factors.CONCLUSIONS C.albicans was the major pathogen in our hospital during 14 years;the candidemia is related with the use of quinolones,ventilator,central venous catheters and radiation-chemotherapy(P

In November 1981,an ancient female cadaver of Qidan nationality in wulanchatu League of InnerMongolia was excavated.This cadaver was estimated approximately 25 year of age.She has been buriedfor about 900 years.The cadaver was a mummified corpse,and preserved in a comparatively intact state. The hair was intact and dark brown in colour.All viseral organs were dreg-like and dark brown incolour.The individual organ could not be identified from its exernal appearance.Only lungs werepreserved,adhering to the back of the thoracic cavity and looked like dry leaves.The peritonem wasdry and translucent and contained a few blood vessels.The muscles were also dry and dark brown or brownishgray in colour.The alveoli and the parenchma of the lung as well as bacterial spores were identified.The histologicalstructure of tissues from the heart region looked like the cross section of cardiac fiber.Collagenous fiberswere seen.Other tissues were mostly autolyzed.The cadaver were group B.According to results of toxic analysis,larger amount of arsenic was demonstratedin tissues from the stomach region.So it was deduced that the lady might die of an arsenical poisoning.Factors involving in the well preservation of this case are discussed.
