Objective:To investigate the staging of cardiovascular-kidney-metabolic (CKM) syndrome before onset, and to analyze its impact on short-term prognosis in patients with acute myocardial infarction (AMI).Methods:The clinical data of 2 993 patients with AMI from January 2017 to December 2023 in Xuanwu Hospital, Capital Medical University were retrospectively analyzed. The basic information, baseline data, in-hospital data, cardiac-related examination results, CKM syndrome staging and in-hospital outcomes were recorded.Results:Among the 2 993 patients with AMI, the CKM syndrome stage 0 was in 23 cases (0.77%), stage 1 in 35 cases (1.17%), stage 2 in 2 015 cases (67.32%), stage 3 to 4 in 920 cases (30.74%). The male proportion, high density lipoprotein-cholesterol (HDL-C) and neutrophil-to-lymphocyte ratio in patients with CKM syndrome stage 0 and 1 were significantly higher than those in patients with CKM syndrome stage 2 and 3 to 4, the hypertension proportion, diabetes proportion, chronic kidney disease proportion, triglyceride (TG), glycated hemoglobin (HbA 1c) and creatinine were significantly lower than those in patients with CKM syndrome 2 stage 3 to 4, and there were statistical differences ( P<0.05); the body mass index (BMI) and non-ST-elevation myocardial infarction (NSTEMI) proportion in patients with CKM syndrome stage 0 were significantly lower than those in patients with CKM syndrome stage 1, 2 and 3 to 4, and there were statistical differences ( P<0.05); the cerebrovascular diseases proportion, Killip stage ≥3 proportion, N-terminal pro-brain natriuretic peptide (NT-proBNP) and left main coronary artery lesions proportion in patients with CKM syndrome stage 0, 1 and 2 were significantly lower than those in patients with CKM syndrome stage 3 to 4, and there were statistical differences ( P<0.05); the global registry of acute coronary events score (GRACE score) in patients with CKM syndrome stage 0 was significantly lower than that in patients with CKM syndrome stage 3 to 4, and there was statistical difference ( P<0.05). Although there were statistical differences in low density lipoprotein-cholesterol (LDL-C) and number of blood vessels involved among the four groups ( P<0.05), but pairwise comparisons showed no statistically significant differences ( P>0.05). There were no statistical differences in age, smoking history, hyperlipidemia, high-sensitivity C-reactive protein, uric acid, cardiac troponin I (cTnI) peak, left ventricular ejection fraction and left ventricular end-diastolic diameter among the four groups ( P>0.05). The incidence of in-hospital major adverse coronary events (MACE) was 10.76% (322/2 993). Among them, the incidence of MACE, all-cause mortality and longer length of stay in patients with CKM syndrome stage 0, 1 and 2 were significantly lower than those in patients with CKM syndrome stage 3 to 4: 4.35% (1/23), 8.57% (3/35) and 8.59% (173/2 015) vs. 15.76% (145/920), 0, 2.86% (1/35) and 2.38% (48/2 015) vs. 4.78% (44/920), (8.17 ± 3.87), (8.15 ± 5.32) and (8.89 ± 6.42) d vs. (9.81 ± 9.29) d, and there were statistical differences ( P<0.05); the incidences of acute kidney injury and atrial fibrillation in patients with CKM syndrome stage 0 and 1 were significantly lower than those in patients with CKM syndrome stage 2 and 3 to 4: 8.70% (2/23) and 8.57% (3/35) vs. 24.17% (487/2 015) and 34.35% (316/920), 0 and 0 vs. 3.52% (71/2 015) and 10.00% (92/920), and there were statistical differences ( P<0.05); there were no statistical differences in the incidences of ventricular tachycardia/ventricular fibrillation, cardiac arrest, mechanical complications and mechanical circulatory support among the four groups ( P>0.05). Conclusions:The severity of CKM syndrome is closely related to the occurrence of AMI. CKM patients with higher CKM stages have more severe AMI and poorer in-hospital prognosis. CKM syndrome staging can serve as a potential prognostic indicator for AMI patients.

Objective To assess the role of the ferroptosis-associated gene GLS2 in the prognosis of pan-cancer and immunity using bioinformatics methods. Methods GLS2 expression levels in pan-cancer were profiled using publicly available databases: The Cancer Genome Atlas, GTEx, Cancer Cell Line Encyclopedia and the International Cancer Genome Consortium. The aim was to explore the role of GLS2 gene expression, gene variation survival analysis, immune infiltration, immune checkpoint related genes, TMB, and MSI in different tumors. Results Difference in GLS2 expression levels between cancer and paraneoplastic tissues was statistically significant in most cancer types, and the expression level was correlated with survival in these cancer types. A positive correlation was found between GLS2 expression and immune cell infiltration in multiple cancer types, and GLS2 expression level was positively correlated with TMB, MSI, and methylation, and its expression is an indicator for potential therapeutic response. Conclusion Pan-cancer analysis shows that the ferroptosis-related gene GLS2 can be used as a diagnostic and prognostic marker of clear cell carcinoma of kidney, adrenocortical carcinoma, lung adenocarcinoma, and pancreatic cancer.

Ferroptosis is a novel regulatory cell death characterized by iron dependence and mainly caused by the accumulation of lipid peroxides and reactive oxygen species in the cell. This process plays an important role in the development of many malignancies, and has been extensively studied in lung cancer, especially in antitumor therapy. In recent years, the role of ferroptosis in tumor immunotherapy has been gradually explored. Studies showed that targeting ferroptosis can improve the therapeutic efficacy of antitumor immunotherapy. In addition, immunotherapy and ferroptosis can work synergistically to enhance the effectiveness of antitumor therapy, suggesting a potential relationship between ferroptosis and immunotherapy and the possible reversal of immune drug resistance. This study aims to elucidate the characteristics of ferroptosis, and the role and potential clinical applications of ferroptosis in the antitumor immunotherapy of advanced non-small cell lung cancer. We also explore the role of some nanomaterials that target the onset of tumor ferroptosis in facilitating immunotherapy.

Objective:To summarize the anesthesia management of living small bowel transplantation.Methods:Severn patients undergoing living and allogeneic small bowel transplantation for the first time were selected.The intraoperative hemodynamics, indexes of blood gas analysis, body temperature and blood transfusion and volume of liquid infused were analyzed.Postoperative outcomes were tracked.Results:Six cases survived and were successfully discharged from hospital successfully, and one patient died.In the operation room, 71% patients were successfully extubated after surgery.Compared with the values during anatomical separation period, Hb during vascular anastomosis and intestinal reconstruction periods and concentration of Ca 2+ during intestinal reconstruction period were significantly decreased, and the blood glucose concentration during vascular anastomosis period were increased ( P<0.05 or 0.01). Compared with the values during vascular anastomosis period, the blood glucose concentration was increased significantly during intestinal reconstruction period ( P<0.05). Crystalloid solution (57±30) ml/kg and colloid solution which mainly containing 20% albumin (15±13) ml/kg were infused mainly during anatomical separation and vascular anastomosis periods in all the patients. Conclusion:The condition of successful living small bowel transplantation is fully evaluation and preparation before surgery.Intravenous-inhalational anesthesia combined with transverses abdominis plane block and rational infusion of colloid solution with vasoactive drugs to maintain hemodynamics stability and monitor blood gas, body temperature, active adjustment of electrolytes and internal environment and stable body temperature can be helpful in maintaining perioperative stable vital signs during the perioperative period, removing the tracheal tube early at the end of surgery, and reducing the development of postoperative complications in patients undergoing living small bowel transplantation.

Objective: To develop the Adolescent Mental Health Literacy Assessment Questionnaire (AMHLAQ), and to evaluate its reliability and validity among undergraduates. Methods: On the basis of the definition of mental health literacy (MHL) and the Knowledge, Attitudes and Practices (KAP) theory, this study constructed a total of 36 items consisting of four dimensions, and scores were measured according to a five point Likert type scale. Using a cluster sampling method, a questionnaire survey was conducted among 3 826 freshmen and sophomore students from two medical schools in Anhui Province. The items were screened by performing t tests, Pearson s correlation coefficient analysis and factor analysis. The reliability and validity of the questionnaire were evaluated using indicators including homogeneity reliability, the split half reliability coefficient, and construct validity. Results: Factor analysis revealed that the AMHLAQ consisted of 22 questions grouped into four domains. The variance cumulative contribution rate was 62.213%. The reliability result showed that the Cronbach s alpha coefficient of the total questionnaire was 0.897, the split half reliability was 0.800, the Cronbach s coefficient of each dimension was 0.796 to 0.885, the split half reliability of each dimension was 0.725 to 0.846, and the indicators had a high level of reliability. Confirmatory factor analysis showed that the model fit was good ( χ 2/df =19.319, P <0.01; RMSEA=0.069). Conclusion AMHLAQ is consistent with the evaluation standard of psychometrics, has good reliability and validity, and can be used to estimate the level of MHL among undergraduates.

Objective: To explore the association between middle school students health literacy and bully victimization and associated sex difference, and to provide guidance for bully prevention in adolescents. Methods: During November 2017 to January 2018, 18 900 junior and senior high school students were enrolled from Hefei of Anhui Province, Shenyang of Liaoning Province, Yangjiang of Guangdong Province and Chongqing by multistage cluster sampling. A self rated questionnaires were used to collect demographic information, health literacy, and bully victimization. Group differences by different characteristics and the association between health literacy and bully victimization were analyzed. Results: The detection rates of campus and cyber bullying victimization were 15.8% (2 992/18 900) and 9.1% (1 723/18 900). Boys, junior high school students, students with poor family financial status and few close friends had a detection rate of 28.0%, 18.8%, 23.3%, and 33.6% of school bullying, which are higher than those of the control group ( χ 2=225.64, 148.07, 141.13, 143.49, P <0.01); boys, students with poor household income and few close friends, the detection rates of cyber bullying were 10.9%, 14.4%, and 20.1%, respectively, are higher than the control group ( χ 2=62.96, 112.82, 88.49, P <0.01). Multivariate Logistic regression analysis indicated that students with low overall and dimensions scores of health literacy were more likely to suffer from campus and cyber bullying, except for the dimension of physical activity. In addition, at all levels of health literacy, males are more likely to be bullied than females ( P <0.05). Conclusion Health literacy of middle school students is related to bully victimization, which is sex specific. Intervention programs of bullying should focus on health literacy enhancement.

Objective: To explore the association between health literacy and drinking behaviors among middle school students in six provinces of China, and to provide scientific basis for the prevention and intervention of drinking behaviors. Methods: From November 2015 to January 2016, 22 628 students were enrolled from Ulanqab, Shenyang, Xinxiang, Bengbu, Chongqing and Yangjiang by multistage stratified cluster sampling method. And a questionnaire survey was conducted among them to collect demographic information, health literacy and drinking behaviors. Rates on drinking behaviors were compared in students with specific characteristics. Multiple Logistic regression analyses were conducted to examine the association between health literacy and drinking behaviors. Results: The proportion of ever drinking, current drinking, binge drinking, drunkenness was 60.0%(13 580), 16.8%(3 799), 5.9%(1 344) and 9.9%(2 250), respectively. After adjusting for gender, grade, family address, siblings, accommodation type, parental educational level, and self reported family income, compared to the high level health literacy, the low level health literacy was significantly associated with ever drinking (OR=1.76, 95%CI=1.62-1.91), current drinking(OR=1.37, 95%CI=1.23-1.52), binge drinking (OR=1.39, 95%CI=1.18-1.63), and drunkenness(OR=1.68, 95%CI=1.47-1.92), respectively(P<0.01). Conclusion Health literacy of middle school students was related to drinking behaviors. The occurrence of health risk behaviors such as drinking can be prevented and reduced by improving students health literacy level.
