Objective:
To investigate the relationship between adverse childhood experiences (ACEs) and mental health status through network analysis in college students, so as to provide empirical evidence for the development of targeted intervention programs.
Methods:
From October to November 2023, a survey was conducted on 1 974 college students from three universities in Hubei Province by using ACEs Questionnaire and Symptom Checklist-90 (SCL-90). The network analysis method was used to construct a network structure to analyze the association between ACEs and SCL-90 symptom factors among college students.
Results:
The network structure of SCL-90 symptom factors and ACEs was stable, each forming a relatively tight cluster; there were 89 non zero edges between ACEs and SCL-90 symptom factors. Emotional neglect-depression played a significant pathway role in connecting the ACEs and SCL-90 symptom factors network. Depression, anxiety, and interpersonal sensitivity of SCL-90 symptom factors had the highest centrality in the ACEs and SCL-90 symptom factors network. Emotional neglect and physical neglect in ACEs and depression and psychoticism in SCL-90 symptom factors had a high node bridge expected influence, acting as Touchpoints to activate the whole network.
Conclusion
Early identification and intervention of emotional and physical neglect, with a focus on depression, anxiety, and interpersonal sensitivity symptoms of childhood neglected individuals, which is beneficial for improving the overall mental health level of college students.

Objective:To investigate the effectiveness and safety of bortezomib combined with conventional chemotherapy regimens for treatment of relapsed/refractory acute B lymphoblastic leukemia (B-ALL).Methods:Twenty patients with relapsed/refractory B-ALL treated with bortezomib combined with chemotherapy in Jiaozuo People's Hospital Affiliated to Xinxiang Medical College, Jiaozuo Coal Industry Group Central Hospital and the Second People's Hospital of Jiaozuo from September 2021 to June 2022 were collected, and their treatment response and prognosis were retrospectively analyzed.Results:The median age of the 20 patients was 49.5 years old (25.0-58.5 years old); 12 were male and 8 were female; 12 were relapsed and 8 were refractory. All patients completed 1 course of bortezomib (1.6 mg/m 2, subcutaneous injection on days 2 and 16) combined with chemotherapy. Before bortezomib treatment, there were 0 case of complete remission (CR), 7 cases of partial remission (PR) and 13 cases of non-remission (NR) in 20 patients, the objective remission rate (ORR) was 35% (7/20), and all were positive for minimal residual disease (MRD). After bortezomib treatment, there were 13 cases of CR, 3 cases of PR and 4 cases of NR, and the ORR was 80% (16/20); the MRD of all patients decreased, among which 13 cases (65%) turned to negative; the differences were statistically significant when comparing CR rate, ORR and MRD negative conversion rate before and after bortezomib treatment ( χ2 values were 65.41, 8.83 and 19.30, all P < 0.05). Four of the 20 patients developed central nervous system infiltration despite bone marrow remission, and one died from post-chemotherapy infection. Myelosuppression occurred in all patients, the incidence of infection was 90% (18/20), and the incidence of digestive system adverse effects was 75% (15/20). Conclusions:Bortezomib combined with conventional chemotherapy regimens is effective and well tolerated in the treatment of relapsed/refractory ALL, and has the potential to enable patients with multi-drug resistant relapse to overcome resistance and to achieve deep remission.

Background: Dysregulation of intestinal flora is a key risk factor for colorectal cancer (CRC). In recent years, traditional Chinese medicine preparations and probiotics have been increasingly applied in the prevention of CRC. Aims: To investigate the preventive effect of Panax notoginseng saponins (PNS) combined with Bacillus subtilis on CRC. Methods: Thirty female BALB/c mice were randomly divided into normal control group (NC group), model group, PNS group, Bacillus subtilis group and PNS combined with Bacillus subtilis group (PaB group). CRC mice model was constructed by azoxymethane (AOM)/dextran sulfate sodium (DSS) method. During the experiment, the mice were weighed, and disease activity index (DAI) score was evaluated. The length of colorectum and tumor number were measured. Serum interleukin (IL) - 6 and IL - 10 contents were determined by ELISA. 16S rRNA sequencing was used to analyze the composition of intestinal flora. Results: Compared with model group, DAI score was significantly decreased (P<0.001), colorectal length was significantly increased (P<0.001), number of tumor was significantly decreased (P<0.001), tumor volume was significantly decreased (P<0.01), serum IL-6 content was significantly decreased (P<0.000 1), and serum IL-10 content was significantly increased in PaB group (P<0.000 1). The results of intestinal flora sequencing showed that Simpson index was significantly decreased in PaB group than in model group (P<0.05), Shannon index and Chao index were significantly increased (P<0.05), abundance of Bacteroidota was significantly increased (P<0.01), abundances of Firmicutes, Helicobacter and Oscillibacter were significantly decreased (P all <0.05), abundance of Lactococcus was significantly increased (P<0.05). Conclusions: The combination of PNS and Bacillus subtilis can effectively alleviate the occurrence of CRC caused by AOM/DSS, and its mechanism may be related to the improvement of composition of intestinal microbial community.

Objective To comprehensively analyze the clinical outcomes of total cavopulmonary connection (TCPC) in the treatment of functional single ventricle combined with heterotaxy syndrome (HS). Methods A retrospective analysis was conducted on the patients with functional single ventricle and HS who underwent TCPC (a HS group) in Guangdong Provincial People's Hospital between 2004 and 2021. The analysis focused on postoperative complications, long-term survival rates, and identifying factors associated with patient survival. Early and late postoperative outcomes were compared with matched non-HS patients (a non-HS group). Results Before propensity score matching, 55 patients were collected in the HS group, including 42 males and 13 females, with a median age of 6.0 (4.2, 11.8) years and a median weight of 17.0 (14.2, 28.8) kg. Among the patients, there were 53 patients of right atrial isomerism and 2 patients of left atrial isomerism. Eight patients underwent TCPC in one stage. TCPC procedures included extracardiac conduit (n=39), intracardiac-extracardiac conduit (n=14), and direct cavopulmonary connection (n=2). Postoperative complications included infections in 27 patients, liver function damage in 19 patients, and acute kidney injury in 11 patients. There were 5 early deaths. The median follow-up time was 94.7 (64.3, 129.8) months. The 1-year, 5-year, and 10-year survival rates were 87.2%, 85.3%, and 74.3%, respectively. After propensity score matching, there were 45 patients in the HS group and 81 patients in the non-HS group. Compared to the non-HS group, those with HS had longer surgical and mechanical ventilation time, higher infection rates (P<0.05), and a 12.9% lower 10-year survival rate. Multivariate Cox regression analysis identified asplenia was a risk factor for mortality (HR=8.98, 95%CI 1.86-43.34, P=0.006). Conclusion Compared to non-HS patients, patients with HS have lower survival rates after TCPC, and asplenia is an independent risk factor for the survival of these patients.
