Objective:To explore the effectiveness of family-based interventions for adolescent suicide pre-vention using meta-analytic methods.Methods:A meta-analysis was conducted by searching CNKI,VIP,Wanfang,Web of Science,PubMed,APA PsycInfo and The Cochrane Library for randomized controlled trials of family-based interventions for adolescent suicide prevention.Results:A total of 15 RCTs involving 2541 cases were conclu-ded.The results of meta-analysis showed that family-based therapy was effective in preventing adolescent suicide(95％CI:-0.76--0.09,P＜0.05),with a medium effect size for the intervention(g=-0.42),in which there was a significant effect on reducing suicidal ideation(SMD=-0.77,95％CI:-1.31--0.23,P＜0.05),and the effect on reducing suicide attempts was not significant(OR=0.87,95％CI:0.68-1.11,P＞0.05).Family-based therapies were most effective in adolescent suicide prevention when the duration of the intervention was 12 weeks or more,when they were based on attachment-based family therapy(ABFT)or resource support and safety plans,and when they had a reasonably high dropout rate(Ps＜0.05).Conclusion:Family-based therapy has significant inter-vention effects on adolescent suicide prevention,and intervention effects on suicidal ideation are superior to those on suicide attempts.

Objective: To explore research hotspots and trends on suicide prevention and intervention among students in the past decade, and to provide a reference for relevant domestic research and practice. Methods: The CiteSpace software was used to visually analyze 1 559 articles on student suicide prevention and intervention in Web of Science core collection database from 2013 to 2022. Results: The number of articles on student suicide prevention and intervention increased from 84 in 2013 to 254 in 2021. Among them, the United States ranked first with 825 articles, and China ranked second with 221 articles. High frequency keywords included risk factors, suicidal ideation, depression and mental health. And high centrality keywords included harm, life, homosexuality and identity. Cluster analysis yielded 17 class groups. By exploring keyword, we found that the popularity of research topics on student suicide prevention and intervention in the past ten years increased rapidly, covering students from different academic backgrouds, which included suicide risk factors and assessment, help seeking for suicide victims, suicide prevention and intervention methods. Conclusion Learning from international experience, we should strengthen research on student suicide prevention and intervention, pay special attention to the efficeiency of student suicide screening, the gap betweeen the incidence of problems and the rate of help, and try to construct support systems for them.

Objective: To understand social anxiety and relevant factors among graduate students under the normalization stage of COVID-19 epidemic prevention and control. Methods: Using convenience sampling method, an online questionnaire survey on graduate students from 5 universities in Jiangsu Province was conducted. Measurements used in the survey includes General Self Efficacy Scale (GSES), General Alienation Scale (GAS), Interaction Anxiousness Scale (IAS) and self made survey for basic information and household living conditions. Results: The overall score of graduate students self efficacy was (2.58±0.50). Average score was (30.68±6.22) for alienation, and (47.55±8.77) for interaction anxiety, with detection rate of social anxiety being 43.96%. Increased dependence on smartphones and electronic devices ( OR=1.86, 95%CI =1.32-2.61) and high alienation score (medium level: OR=2.06, 95%CI =1.45-2.92; high level: OR=5.19, 95%CI =1.00-27.00) were positively correlated with social anxiety. Increased communication with friends ( OR=0.65, 95%CI =0.47-0.90 and high self efficacy (medium level: OR= 0.37 , 95%CI =0.21-0.66; high level: OR=0.15, 95%CI =0.08-0.30) were negatively correlated with social anxiety. Conclusion At the normalization stage of COVID-19 epidemic prevention and control, social anxiety of graduate students is one of the mental health issues which need further attention. Participation in peer support helps prevent social anxiety through developing self efficacy, alleviating individual alienation, and reducing dependence on electronic devices among graduate students.

Objective To evaluate the effect of Jatropha see soma japonicum so as to screen the optimum process and formulations. Methods The cercaria directly contacting tests with Jatro-pha seed oils extracted by 6 different extraction processes were carried out,and the mouse immediate contacting cercaria infection trials with different formulations of Jatropha seed oil and various additives were performed. Results With 95%ethanol,the ratio of material to liquid being 1∶8,and 2 h extraction,the oil extraction rate was 30.7%. The cercaria directly contacting tests showed that 6 kinds of Jatropha seed oil killed all cercaria within 30 min. In the mouse immediate contacting cercaria infection trials,the worm declined rate of Jatropha seed oil liquid was 70.97%,and the worm declined rate of the sample added with benzyl benzoate was 58.87%,and the worm declined rate of the sample added with laurocapram was 77.42%. The worm declined rate of the sam-ples added with benzyl benzoate,dibutyl phthalate and laurocapram was 100%. Conclusion The process with 95%ethanol,the ratio of material to liquid being 1∶8,and 2 h extraction is the optimum,and the Jatropha seed oil has a good killing schistosome cercaria effect.
