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.

Objective:To summarize the clinical features and prognosis of Budd-Chiari syndrome with hepatopulmonary syndrome (HPS) in children.Methods:The clinical data of a child who had Budd-Chiari syndrome with HPS treated at the Department of Pediatrics of the First Affiliated Hospital of Zhengzhou University in December 2016 was analyzed retrospectively. Taking "Budd-Chiari syndrome" and "hepatopulmonary syndrome" in Chinese or English as the keywords, literature was searched at CNKI, Wanfang, China Biomedical Literature Database and PubMed up to July 2023. Combined with this case, the clinical characteristics, diagnosis, treatment and prognosis of Budd-Chiari syndrome with HPS in children under the age of 18 were summarized.Results:A 13-year-old boy, presented with cyanosis and chest tightness after activities for 6 months, and yellow staining of the skin for 1 week. Physical examination at admission not only found mild yellow staining of the skin and sclera, but also found cyanosis of the lips, periocular skin, and extremities. Laboratory examination showed abnormal liver function with total bilirubin 53 μmol/L, direct bilirubin 14 μmol/L, and indirect bilirubin 39 μmol/L, and abnormal blood gas analysis with the partial pressure of oxygen of 54 mmHg (1 mmHg=0.133 kPa), the partial pressure of carbon dioxide of 31 mmHg, and the alveolar-arterial oxygen gradient of 57 mmHg. Hepatic vein-type Budd-Chiari syndrome, cirrhosis, and portal hypertension were indicated by abdominal CT venography. Contrast-enhanced transthoracic echocardiography (CE-TTE) was positive. After symptomatic and supportive treatment, this patient was discharged and received oxygen therapy outside the hospital. At follow-up until March 2023, there was no significant improvement in hypoxemia, accompanied by limited daily activities. Based on the literature, there were 3 reports in English while none in Chinese, 3 cases were reported. Among a total of 4 children, the chief complaints were dyspnea, cyanosis, or hypoxemia in 3 cases, and unknown in 1 case. There were 2 cases diagnosed with Budd-Chiari syndrome with HPS at the same time due to respiratory symptoms, and 2 cases developed HPS 1.5 years and 8.0 years after the diagnosis of Budd-Chiari syndrome respectively. CE-TTE was positive in 2 cases and pulmonary perfusion imaging was positive in 2 cases. Liver transplantation was performed in 2 cases and their respiratory function recovered well; 1 case received oxygen therapy, with no improvement in hypoxemia; 1 case was waiting for liver transplantation.Conclusions:The onset of Budd-Chiari syndrome with HPS is insidious. The most common clinical manifestations are dyspnea and cyanosis. It can reduce misdiagnosis to confirm intrapulmonary vascular dilatations with CE-TTE at an early stage. Liver transplantation is helpful in improving the prognosis.
