To explore the mediating role of psychological resilience to childhood abuse and binge eating. This study assessed the childhood abuse, binge eating and psychological resilience of 3 453 middle school students in Harbin city, Heilongjiang Province. SPSS PROCESS macro program, combined with Bootstrap method, was employed to explore the mediating effect of psychological resilience. The incidence of middle school students experiencing at least one type of abuse in their childhood was 81.3% (2 807/3 453). Childhood abuse, psychological resilience and binge eating were all significantly different in terms of gender, household registration and whether they were only child (all P values<0.05). There was a significant positive correlation between childhood abuse and binge eating. Psychological resilience was negatively associated with childhood abuse and binge eating. Childhood abuse could not only directly predict the binge eating behavior of adolescents, but also could indirectly affect it via psychological resilience.

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.

Gallstone disease is a common and frequently seen disease of digestive system, and is a common cause of inflammation of gallbladder and bile duct, biliary tract tumor and obstructive jaundice, however, its pathogenesis is not yet fully understood. Recent studies have revealed that intestinal flora and immunity play important roles in the formation of gallstones. This paper reviewed the relationship between the abundance and composition of intestinal flora, immuno - globulins, mucins and immune cells, as well as the interactions between intestinal flora and biliary immunity and gallstone formation for providing new ideas and methods for gallstone prevention and treatment.

Berberine is an antipyretic and detoxicating drug commonly used in clinical practice,and it is currently used for the routine treatment of gastrointestinal diseases such as bacterial gastroenteritis and diarrhea.However,several recent studies have shown that berberine can exert a therapeutic effect on the diseases such as autoimmune hepatitis,viral hepatitis,nonalcoholic fatty liver disease,and liver cancer by regulating the AMPK and TGF-β pathways and altering the composition of intestinal flora.This provides new drugs for the treatment of these diseases,expands the potential indications of berberine,and provides clues for the follow-up research and development of similar drugs.This article summarizes the therapeutic effect and mechanism of berberine on various liver diseases,in order to provide a reference for effective clinical application.
