Objective: To explore the relationship between abuse experience with suicidal ideation and suicide attempts of junior middle school students, and to provide a reference for suicide prevention of junior middle school students. Methods: Cluster sampling method were used to selct 10 289 junior middle school students from 25 districts and counties of Chongqing were included in the analysis of this study from July to September in 2020. And Questionnaire on Abuse in Childhood and Mental Health Scale for Middle School Students were applied to collect the data about demographic information, suicide ideation and behavior. Results: The prevalence of suicidal ideation and suicide attempts among junior middle school students were 20.93% and 10.83%, respectively. Multivariate Logistic regression model found that after controlling for demographic variables and mental health, emotional abuse ( OR =2.07) and emotional neglect ( OR =2.03) showed higher correlations with suicidal ideation than the other three types of childhood abuse( OR physical neglect =1.19, OR physical abuse =1.60, OR sexual abuse =1.37, P <0.05); and sexual abuse ( OR =2.29) and physical neglect ( OR =1.87) showed higher associations with suicide attempt than the other three types of abuse( OR emotional abuse =1.63, OR emotional neglect =1.59, OR physical abuse =1.50, P <0.01). Conclusion All five types of child abuse were independent risk factors for suicidal ideation and suicide attempts, and emotional neglect and emotional abuse had a greater effect on suicidal ideation, sexual abuse and physical neglect had a greater effect on suicide attempts.

Pancreatitis is one of the most common inflammatory diseases of the pancreas caused by autodigestion induced by excessive premature protease activation. However, recognition of novel pathophysiological mechanisms remains a still challenge. Both genetic and environmental factors contribute to the pathogenesis of pancreatitis, and the gut microbiota is a potential source of an environmental effect. In recent years, several new frontiers in gut microbiota and genetic risk assessment research have emerged and improved the understanding of the disease. These investigations showed that the disease progression of pancreatitis could be regulated by the gut microbiome, either through a translocation influence or in a host immune response manner. Meanwhile, the onset of the disease is also associated with the heritage of a pathogenic mutation, and the disease progression could be modified by genetic risk factors. In this review, we focused on the recent advances in the role of gut microbiota in the pathogenesis of pancreatitis, and the genetic susceptibility in pancreatitis.
