Ferroptosis is an iron-dependent cell death modality triggered by the accumulation of lipid peroxides and is closely linked to tumor pathogenesis. Ferritinophagy refers to the selective autophagic degradation of ferritin, releasing intracellular stored iron to maintain iron metabolic homeostasis. This process is also significantly associated with tumor-targeted interventions. This review systematically elucidates the mechanisms of ferroptosis and ferritinophagy, their roles in tumor progression, and the therapeutic potential of pharmacologically induced ferritinophagy in anticancer strategies.

Objective To analyze the epidemiological and etiological characteristics of hand,foot and mouth disease(HFMD)in Nanning City,Liangqing District from 2012 to 2023.Methods Descriptive epidemiological methods were used to describe the three distribution characteristics of HFMD,and to predict the incidence trend of HFMD.Results From 2012 to 2023,Liangqing District of Nanning City reported a total of 19 715 cases of HFMD.The incidence rates varied significantly across different years,with statistically significant differences(P＜0.01).The urban area reported the highest number of cases.The disease primarily occurred from April to October,with the highest incidence among children aged 6 months to 5 years,mainly among children in daycare and preschools.From 2012 to 2023,a total of 588 cases were diagnosed through laboratory tests,with the highest detection rate of other enteroviruses,and a relatively lower detection rate of EV71.Predictions indicate that the incidence of HFMD in Liangqing District of Nanning City will decrease in 2025 compared to 2023.Conclusion Incidence of HFMD in Liangqing District,Nanning is high,especially among children aged 6 months to 5 years.It is suggested to strengthen the epidemic surveillance,continue to carry out pathogen surveillance.

Objective:To analyze the risk factors of bacterial infection in patients with liver cirrhosis complicated with gastroesophageal varices after gastroscopy, and to construct a prediction model.Methods:Patients with gastroesophageal varices due to cirrhosis who underwent gastroscopy in the Third Hospital of Hebei Medical University from January 2021 to May 2023 were enrolled. All patients were divided into infection group and non-infection group according to whether bacterial infection occurred after gastroscopy. The detection of pathogens in the infection group and the source of specimens were analyzed. Multivariate binary logistic regression was used to analyze the risk factors of postoperative bacterial infection in patients with cirrhosis and gastroesophageal varices. The nomogram was drawn by R language to construct a risk prediction model. Receiver operator characteristic curve (ROC curve), calibration curve, Hosmer-Lemeshow test and decision curve were used to evaluate the model.Results:Among the 480 patients, 57 had postoperative bacterial infection and 423 had no infection. The incidence of infection was 11.88%(57/480). Seventy bacterial culture positive samples were obtained, mainly from blood and respiratory tract (30 samples (42.86%) and 25 samples (35.71%), respectively). A total of 82 strains of pathogenic bacteria were isolated, including 16 strains of Escherichia coli and 14 strains of Staphylococcus aureus. Multivariate binary regression analysis showed that length of hospital stay (odds ratio ( OR)=1.13, 95% confidence interval ( CI) 1.06 to 1.20, P<0.001), age ( OR=1.06, 95% CI 1.02 to 1.10, P=0.006), model for end-stage liver disease combined with sodium (MELD-Na) score ( OR=1.10, 95% CI 1.02 to 1.18, P=0.014), diabetes ( OR=1.25, 95% CI 1.07 to 1.96, P=0.043) and emergency gastroscopy ( OR=2.95, 95% CI 1.20 to 7.25, P=0.019) were independent risk factors for bacterial infection after gastroscopy in patients with cirrhosis and gastroesophageal varices. Based on the above risk factors, a nomogram prediction model was constructed. The results of ROC curve analysis showed that the area under the curve of the nomogram model for predicting bacterial infection after gastroscopy of gastroesophageal varices in cirrhosis was 0.82 (95% CI 0.73 to 0.90). The slope of the calibration curve was 0.98(95% CI 0.92 to 1.04), indicating that the predicted probability of the model was in good agreement with the actual probability. The results of Hosmer-Lemeshow test showed that the nomogram model fitted well ( χ2=6.35, P=0.415). The decision curve analysis showed that the clinical net benefit rate of the nomogram model was >0 when the threshold probability was 0.039 to 0.410. Conclusions:Older age, length of hospital stay, MELD-Na score, history of diabetes, and emergency gastroscopy are independent risk factors for bacterial infection after gastroscopy in patients with cirrhosis and gastroesophageal varices. The prediction model constructed in this study has a good predictive value for bacterial infection in such patients.

Objective:Bibliometric analysis was performed to map scientific knowledge landscape, so that to explore the research status and future trends in the field of carbapenem-resistant Gram-negative bacteria (CRGNB) over the past decade.Methods:Literature on CRGNB published between January 1st, 2015 and December 31st, 2024 was retrieved from the China National Knowledge Internet (CNKI) database and Web of Science Core Collection (WoSCC). VOSviewer and CiteSpace were used for bibliometric analysis.Results:A total of 3 340 Chinese and 10 761 English publications were included in this study. The annual Chinese publications remained stable, while English publications exhibited a linear growth. It was anticipated that the English publications would decline in the forthcoming years, although remaining high. China contributed the highest number of publications, and Zhejiang University was the institution with the largest number of publications. Bonomo RA, Chen L, etc. were high-impact authors in the field of CRGNB and had formed a stable cooperative group. Antimicrobial Agents and Chemotherapy was the journal with the largest number of publications. High-frequency keywords in the domain of CRGNB were comprehensively categorized into four distinct clusters, including carbapenem resistance mechanisms and gene transmission, antimicrobial drugs and combination therapy, management of critically ill patients, and infections and colonization. It was imperative to acknowledge the significance of all of these research areas. Burst word analysis suggested that carbapenem-resistant Enterobacterales virulence genes as well as new isoforms of Klebsiella pneumoniae carbapenemase (KPC) had become a research hotspot. Conclusions:The issue of carbapenem resistance remains a significant concern. Current research focus on the resistance mechanisms and antimicrobial agents, highlighting its significant academic advancement and practical applications. Fostering international collaboration through academic exchanges between research teams worldwide is imperative to establish robust cooperative relationships, facilitate multidisciplinary cooperation, and promote high-quality research.

Myocardial infarction (MI) is the leading cause of cardiovascular disease-related death worldwide. Nonetheless, existing therapeutic approaches for MI are hampered by issues such as reliance on pharmacological agents and suboptimal patient adherence. Caffeic acid (CA) is a bioactive polyphenolic compound with important anti-inflammatory, anti-bacterial and anti-oxidant functions. Still, its specific role and mechanism in treating cardiovascular disease remain to be further studied. In recent years, a large number of studies have shown that the kelch-like ECH-associated protein 1/nuclear factor erythroid 2 related factor 2 (Keap1/Nrf2) pathway is a key factor in the occurrence and development of cardiovascular diseases. In this study, H₂O₂-induced oxidative stress model of H9c2 cells and left anterior descending branch (LAD) conjunctival induced acute myocardial infarction reperfusion (AMI/R) model were used to evaluate the protective effect of CA on the heart. The interaction between CA and Keap1 was analyzed by CA-labeled fluorescence probe, target fishing, isothermal titration calorimetry (ITC), protein crystallography and surface plasmon resonance (SPR). Our results suggested that CA binds Keap1 and degrades Keap1 in a p62-dependent manner, further promoting nuclear transcription of Nrf2 and thus effectively reducing oxidative stress. In addition, based on the three-dimensional eutectic structure, it was confirmed that CA directly targets Keap1 protein by interacting with residues M550 and N532, inducing conformation changes in Keap1 protein. We also found that the CA analog chlorogenic acid (GCA) can bind Keap1. In conclusion, this study elucidates a novel molecular mechanism and structural basis for the protective effects of CA against oxidative damage via the Keap1-Nrf2 pathway.
