1.Analysis of the characteristics and influencing factors of new-onset suicidal behaviors among junior and senior high school students
Chinese Journal of School Health 2026;47(9):1330-1334
Objective:
To investigate the incidence and influencing factors of new onset suicidal behaviors among junior and senior high school students, so as to provide evidence for early warning and intervention.
Methods:
Using a cluster sampling method, baseline data were collected from September to November 2023 among 2 379 adolescents selected from 2 junior high schools, 2 general senior high schools and 2 vocational senior high schools in Wuhan, Hubei Province, with follow up carried out from September to November 2024. Data were collected using the School Adaptation Scale, the Essential Resilience Scale, the Personal Social Support Scale, the Adverse Childhood Experiences Questionnaire, the Adolescent Life Events Scale, the Pittsburgh Sleep Quality Index, the Center for Epidemiologic Studies Depression Scale, and the Columbia-Suicide Severity Rating Scale. Multivariate Logistic regression analysis was used to identify factors influencing new onset suicidal behavior among junior and senior high school students.
Results:
Among junior and senior high school students without suicide risk at baseline, 53.55% remained stable risk free during follow up, while 13.28% developed new suicidal behavior during follow up, of which suicidal ideation, suicide plan and suicide attempts accounted for 11.69%, 8.83% and 6.52%, respectively. Multivariate Logistic regression revealed that increased depressive symptoms at follow up elevated the risk of overall new onset suicidal behaviors ( OR =4.14), ideation ( OR = 4.59), plans ( OR =4.24), and attempts ( OR =4.09); poor sleep quality also increased the risk of overall new onset suicidal behaviors ( OR =2.23), plans ( OR =2.03), and attempts ( OR =2.65) (all P <0.05). Non boarding junior and senior high school students had lower risks of overall new onset suicidal behaviors and ideation ( OR=0.70 and 0.49, respectively); secondary school students with academic performance ranking in the top 20%-30% of their class had a lower risk of new onset ideation ( OR =0.27); and those whose place of origin was outside the city had a lower risk of new onset plans ( OR =0.49) (all P <0.05).
Conclusions
New onset suicidal behaviors among junior and senior high school students exhibit dynamic and stage specific differences. Depressive symptoms serve as a common core risk factor across all stages, whereas sleep quality, academic performance, boarding status, and place of origin exert differential influences at distinct stages.

The deep integration of artificial intelligence (AI) and multimodal data in the medical field presents vast application prospects, with its implementation in robotic surgery still in the early stages. Surgical robots assist surgeons in decision-making and operation through quantifiable data and visualized imaging, where data serves as the key driver of innovation for AI in robotic surgery. AI is pushing the boundaries of robotic autonomy, enhancing the surgical experience and improving both the quality and efficiency of procedures. This paper focuses on artificial intelligence surgery, especially the key applications of AI in robotic gastrointestinal surgery, systematically reviewing recent advances in surgical scene enhancement, surgical phase recognition, instrument tracking, intraoperative force feedback, and autonomous manipulation. Furthermore, it discusses major challenges including the scarcity of high-quality data, limited interpretability of algorithms, and the need for real-time performance. Although fully autonomous robotic surgery remains a long-term goal, the pathway toward progressive implementation is becoming increasingly clear.

Objective To summarize and analyze the perioperative complications of irreversible electroporation (IRE) ablation in treating tumors at different locations and to discuss their managements. Methods A total of 200 patients with tumors, including pancreatic tumor (n=71), liver tumor (n=64) and other tumors (n =65), were enrolled in this study. All patients received IRE ablation treatment. The perioperative complications were recorded and the data were statistically analyzed. The causes of severe complications and the treatment of complications were discussed. Results None of the patients died during the course of IRE ablation procedure. Severe postoperative complications occurred in the patients with pancreatic tumor or liver tumor, including duodenal artery bleeding in 3 patients with pancreatic tumor, which occurred at 10 days, 11 days and 15 days after IRE ablation respectively, and gastrointestinal bleeding (n =1) and biliary septic shock (n=1) in 2 patients with liver tumor, which occurred at 9 days after IRE ablation, the clinical symptoms were controlled after interventional embolization and/or vascular ligation together with anti-infective therapy. All minor complications were relieved after symptomatic treatment within 14 days. Conclusion IRE ablation has less systemic inflammatory response, and both the intraoperative and postoperative adverse reactions can be easily controlled, besides, IRE ablation has higher clinical safety. Although IRE ablation procedure may damage the internal or peripheral vessels of the pancreatic tumor, this severe complications can be effectively avoided if proper measures are adopted based on the causes of complications.

Objective To discuss the clinical value of magnetic resonance diffusion-weighted imaging (MR-DWI) in distinguishing tumor remnants from tumor necrosis of pancreatic carcinoma after cryoablation treatment.Methods Conventional MRI T1WI,T2WI scan,DWI sequence and dynamic enhanced MRI scan were performed in 26 patients with pancreatic carcinoma who were received cryoablation treatment.The changes in MRI signals after cryoablation treatment were recorded.The apparent diffusion coefficient (ADC) values of the normal pancreas,preoperative tumor tissue,postoperative remnants and necrosis tissue were calculated,and the results were compared.The correlation between the ADC values and the size of the tumor was evaluated,and the differences in ADC values among the tumors that had different diameter,location and staging were statistically analyzed.Results Of the 26 patients,complete necrosis of tumor was obtained in 16.The necrotic tumor tissue displayed low-signal on T1WI,high-signal on T2WI and low-signal on DWI,with no enhancement on dynamic enhanced imaging.Active residual tumor tissue was detected in 9 patients,among them the residual tumor diameter >5 cm was seen in 7 patients;the residual rate was 34.6%.ADC values of the following tissue,from low to high in order,were preoperative pancreatic tumor tissue (1.022± 0.126)x10-3 mm2/s,postoperative residual tumor tissue (1.130±0.155)x10-3 mm2/s,normal pancreatic tissue (1.924±-0.124)×10-3 mm2/s and postoperative necrosis tissue (2.312-±0.214)×10-3 mm2/s.No statistically significant difference in ADC values existed between preoperative pancreatic tumor tissue and postoperative residual tumor tissue (P=0.452),while statistically significant difference in ADC values existed between normal pancreatic tissue and postoperative necrosis tissue (P<0.001).The ADC values of pancreatic tumor tissue bore a negative correlation with the tumor size (R=-0.43,P=0.027 2),while the ADC values lacked the relationship to the tumor location as well as to the tumor staging (P=0.738 8 and P=0.089 5 respectively).Conclusion MR-DWI can effectively distinguish the residual tumor tissue from the necrotic tumor tissue of pancreatic carcinoma after cryoablation treatment,which provides reliable basis for further clinical diagnosis and treatment.

Bovine aortic endothelial cells (BAECs) were cultured with high glucose (33 mmol/L), 4 mg/L green tea polyphenols (GTPs) or 4 mg/L GTPs co-treatment with high glucose for 24 h in the presence or absence of Bafilomycin-A1 (BAF). We observed that high glucose increased the accumulation of LC3-II. Treatment with BAF did not further increase the accumulation of LC3-II. Results also showed an increased level of p62 and decreased Beclin-1. However, GTPs showed inversed trends of those proteins. Furthermore, GTPs co-treatment with high glucose decreased the level of LC3-II and a much higher accumulation of LC3-II was observed in the presence of BAF in comparison with high glucose alone. Results also showed a decreased p62 and increased Beclin-1. The results demonstrated that GTPs alleviated autophagy inhibition induced by high glucose, which may be involved in the endothelial protective effects of green tea against hyperglycemia.
