Objective:To summarize the best evidence for postoperative flap management in patients with oral cancer.Methods:Clinical decisions, guidelines, systematic reviews, expert consensus, and evidence summaries on postoperative flap management for patients with oral cancer were searched in databases and websites based on the 6S pyramid of evidence model. The search period was from January 1, 2014, to July 1, 2024. Two researchers trained in evidence-based nursing independently conducted a quality assessment of the literature and extracted the evidence.Results:A total of 14 articels were included, including one clinical decision, two guidelines, one evidence summary, eight systematic reviews, and two expert consensus. Twenty-eighgt pieces of evidence for postoperative flap management in patients with oral cancer were summarized from four aspects of risk factors, flap assessment, protective measures, and treatments.Conclusions:The summarized best evidence for postoperative flap management in oral cancer patients is scientific and applicable. Healthcare professionals need to select and apply the best evidence in a targeted manner, considering the clinical context.

Objective To investigate the expression of ferritinophagy-related gene ELAV-like RNA binding protein 1(ELAVL1)in multiple myeloma(MM)and elucidate its diagnostic and prognostic value for MM.Methods First,we analyzed ELAVL1 expression level in healthy controls and MM patients using data from the GEO and TCGA databases.Subsequently,bone marrow specimens were collected from 28 newly diagnosed MM patients and 20 healthy controls,and qRT-PCR was employed to validate ELAVL1 expression.The diagnostic and prognostic potential of ELAVL1 was assessed using ROC curve analysis and Kaplan-Meier survival curves.Additionally,univariate and multivariate COX regression analyses were performed to identify independent risk factors for MM prognosis.Finally,KEGG and GO enrichment analyses were performed using the DAVID online platform.Results The level of ELAVL1 expression was significantly higher in newly diagnosed MM patients and refractory/relapsed MM patients than in the healthy controls(P＜0.001).Moreover,ELAVL1 expression was positively correlated with the International Staging System(ISS)stage of MM(P＜0.01).Furthermore,qRT-PCR validation confirmed that ELAVL1 expression was elevated in the 28 newly diagnosed MM patients compared to the 20 healthy controls(P＜0.001).ROC curve analysis demonstrated that ELAVL1 could effectively differentiate between newly diagnosed MM patients,healthy controls,and MGUS patients(P＜0.001 and P=0.000 2,respectively).Survival analysis revealed that high ELAVL1 expression was associated with shorter progression-free survival(P=0.0141)and overall survival(P=0.008 0).Univariate and multivariate COX regression analyses identified high ELAVL1 expression as an independent risk factor for poor MM prognosis(P=0.005 0).KEGG analysis suggested that ELAVL1 might be involved in the Hippo and MAPK signaling pathways.Conclusion High ELAVL1 expression in MM may serve as a biomarker for diagnosis and poor prognosis.ELAVL1 may promote MM initiation and progression via the Hippo and MAPK signaling pathways.

Objective:To explore the protective effects and mechanisms of an indole-3-acetaldehyde (I3A)-loaded inulin-based hydrogel against radiation-induced intestinal injury.Methods:The gelation properties and injectability of the I3A-loaded inulin-based hydrogel were detected using a rheometer, and its biocompatibility was assessed via a CCK-8 assay. Eighteen C57BL/6 mice (aged: 6-8 weeks) were stratified by body weight and randomly assigned into three groups with 6 mice in each group: blank control, irradiation-only, and irradiation+ hydrogel protection. Abdominal irradiation was administered using 137Cs γ-rays at 17 Gy. The irradiation+ hydrogel protection group received 200 μl/day of I3A-loaded inulin-based hydrogel for two days before and 2-3 days after irradiation. Meanwhile, the irradiation-only group was treated with an equivalent volume of sterile water via gavage. The mice were euthanized four days post-irradiation, and their intestinal tissues were harvested. Hematoxylin-eosin (HE) staining, Ki67 immunohistochemistry, and TUNEL immunofluorescence were performed to assess histopathological damage, epithelial cell proliferation, and apoptosis, respectively. Quantitative real-time PCR (qRT-PCR) was employed to measure mRNA levels of inflammatory and antioxidant factors. Gut microbiota composition was analyzed via 16S rRNA sequencing. Results:The test results of the rheometer confirmed successful hydrogel formation. CCK-8 assays demonstrated excellent biocompatibility. Compared with the irradiation-only group, the irradiation+ hydrogel protection group exhibited preserved intestinal histoarchitecture, a 1.5-fold increase in intestinal cell proliferation ( t = 8.35, P < 0.05), and a 2-fold reduction in radiation-induced apoptosis ( t = 7.94, P < 0.05). Moreover, the hydrogel group showed significantly elevated expression of the anti-inflammatory cytokine IL-10 and antioxidant factors NRF-2 and HO-1 ( t = 3.16, 24.83, 5.92, P < 0.05), alongside reduced levels of pro-inflammatory cytokines IL-1β, IL-6, and TNF-α ( t = 5.15, 3.82, 3.83, P < 0.05). Gut microbiota analysis revealed significant modulation in microbial composition and abundance in the hydrogel group. Conclusions:The I3A-loaded inulin-based hydrogel can significantly promote intestinal cell proliferation, reduce radiation-induced apoptosis, and enhance both anti-inflammatory and antioxidant responses. In addition, it regulates gut microbiota composition and abundance, protecting against radiation-induced intestinal injury.

As the global population ages and cancer diagnostic and treatment technologies improve, the number of elderly cancer survivors continues to increase, and their complex care needs challenge the traditional mono-disciplinary care model. This paper explores the dilemmas of implementing a long-term care system and suggestions for future research through a comprehensive overview of the care needs of elderly cancer survivors and the progress of interdisciplinary research, with the aim of providing a theoretical basis and practical reference for improving the long-term care system and enhancing patients' quality of life.

Objective:To develop an exercise rehabilitation program based on the Temporal Self-regulation Theory and evaluate its effectiveness in elderly patients with hip fractures.Methods:A total of 84 elderly patients with hip fractures admitted to the Department of Trauma Orthopedics at the First Affiliated Hospital of University of South China from May to August 2024 were enrolled using convenience sampling. Participants were randomly assigned to an experimental group ( n=42) and a control group ( n=42) using a random number table. The control group received routine exercise rehabilitation, while the experimental group received an exercise rehabilitation program constructed based on the Temporal Self-regulation Theory. The program included components such as establishing a unified concept of "exercise-rehabilitation", enhancing time-limited efficacy, achieving behavioral advantages, and improving self-regulation of active movement. Both groups received interventions for 12 weeks. Functional exercise adherence, activities of daily living, and hip joint function were assessed using the Orthopedic Exercise Adherence Scale, Modified Barthel Index, and Harris Hip Score at four time points: before intervention, on the day of discharge, and at 4 and 12 weeks postoperatively. Results:During the study, two patients from each group dropped out. Results of the generalized estimating equations showed group effects, time effects, and interaction effects in adherence scores with statistically significant differences ( P<0.01). On the day of discharge, and at 4 and 12 weeks postoperatively, the adherence scores in the experimental group were significantly higher than those in the control group, and the differences were statistically significant ( P<0.05). Repeated measures ANOVA indicated that group effects, time effects, and interaction effects were also statistically significant in scores for daily living ability and hip joint function ( P<0.05). The experimental group scored higher than the control group at each time point with statistically significant differences ( P<0.05) . Conclusions:The exercise rehabilitation program based on the Temporal Self-regulation Theory is scientifically sound and practical. It can effectively improve functional exercise adherence, enhance daily living ability, and promote postoperative recovery of hip joint function in elderly patients with hip fractures.

Pasteurella multocida(Pm)type A is an important pathogen responsible for respiratory diseases,such as bovine pneumonia,which seriously restricts the development of cattle industry in China.Currently,the prevention of Pm infection-related diseases primarily relies on vaccination in production.However,the diverse Pm serotypes result in inadequate cross-immunological protection from vaccines.Therefore,it is of great significance to develop vaccines with cross-protection for the prevention and control of Pm infectious diseases.The previous studies conducted by our team have demonstrated that PmCQ2△cra exhibits a strong immune protective effect against Pm type A(PmA),Pm type B(PmB),and Pm type F(PmF).Transcriptomic sequencing results suggest that the cross-immunoprotective effect of PmCQ2△cra may be attributed to high expression levels of bacterial surface protective antigens.Consequently,four putative immune protective antigens,namely PmCQ2-5175,PmCQ2-6290,PmCQ2-0275 and PmCQ2-2640,were screened through bioin-formatics analysis in this study.Subunit vaccines formulated with these potential antigenic proteins exhibited protective efficacy of 62.5％,25％,12.5％and 10％against PmA-infected mice,respectively.Importantly,PmCQ2-5175,one of the most protective single-component antigen vac-cines,demonstrating a 75％cross-protection against PmB infection in mice.Furthermore,the pro-tective efficacy of the PmCQ2-5175 protein screened in this study was superior to that of the previ-ously reported Pm antigen protein plpE.Moreover,the fusion expression protein PmCQ2-5175-PLPE exhibited better protective effects against PmA compared to a single protein.The findings of this study will establish a theoretical foundation for the advancement of Pm subunit vaccines with broad-spectrum immune protection.

Objective To propose a whole-life cycle management model for valvular heart disease (VHD), systematically elucidate its underlying logic and implementation pathways, and concurrently review and analyze its preliminary application outcomes. Methods Since 2020, West China Hospital of Sichuan University has established a management system encompassing "assessment-decision-intervention-follow-up", including: (1) a risk-stratified, tiered management pathway; (2) six core functions ("promotion, screening, prevention, diagnosis, treatment, and rehabilitation") coordinated by disease-specific managers; (3) an intelligent decision support information platform; and (4) a collaborative network of multidisciplinary teams and regional academic alliances. To evaluate the effectiveness of this management model, we retrospectively included three cohorts: (1) the population screened by echocardiography from 2020 to 2024, analyzing the detection rate of aortic valve disease and risk stratification; (2) patients enrolled in the whole-life cycle management from April 2021 to December 2024, assessing follow-up outcomes, hospital satisfaction, and changes in quality of life; (3) patients who underwent transcatheter aortic valve replacement (TAVR) from January 2022 to January 2024, evaluating the one-year all-cause mortality rate, perioperative complications, and improvements in New York Heart Association (NYHA) classification. Results Between 2020 and 2024, a total of 583 874 individuals underwent echocardiographic screening. A total of 48 089 patients with aortic valve disease were identified, including 3 401 (7.1%) high-risk patients, 18 657 (38.8%) moderate-risk patients, and 26 031 (54.1%) low-risk patients. Among them, 2 417 patients were enrolled in whole-life cycle management. Patient satisfaction scores showed a yearly increase, rising from 73.89 points before 2020 to 93.74 points in 2024. The 1-year mortality rate in the TAVR cohort decreased to 5.3%, significantly lower than the 8.2% observed under early standard management between 2014 and 2019 (P<0.01). Conclusion Through process optimization and resource integration, the VHD whole-life cycle management model has demonstrated significant effectiveness in standardizing diagnostic and follow-up procedures, enhancing patient satisfaction and quality of life, and reducing mortality. These outcomes highlight its practical value for broader implementation in China.
