Objective:To analyze the relationship between the optimal surgical margin value and clinical prognosis of transoral robotic surgery（TORS） in treating human papillomavirus（HPV） -positive oropharyngeal squamous cell carcinoma. Methods:A single-center, prospective, observational cohort study was conducted, enrolling patients with early and moderated stage（≤T3 stage） oropharyngeal carcinoma undergoing TORS between July 2020 and April 2024. The proposed optimal surgical margin cutoff value for TORS was set as 2 mm. The primary objectives were to evaluate the optimal clear margin for TORS and its association with overall survival（OS） and progression-free survival（PFS）. Logistic regression was used to analyze correlations between surgical margins and clinical variables, while Cox regression models assessed the impact of surgical margins on OS and PFS. Results:A total of 90 patients（60 males, 66.7%） were included, all had squamous cell carcinoma, with a mean age of 58.0±9.0 years（range: 39-84 years） old. The 1, 2 and 3-year OS rates were 92.3%, 89.9% and 85.0%, respectively, while the 1, 2 and 3-year PFS rates were all 90.1%. For surgical margins ≤2 mm, the 1, 2 and 3-year OS rates were 80.8%, 69.3% and 69.3%, respectively, and PFS rates were 77.9% across three time points. For surgical margins>2 mm, the 1, 2 and 3-year OS rates were 96.5%, 96.5% and 90.6%, respectively, with PFS rates of 94.6%. Logistic regression showed no correlation between surgical margins and tumor type, T/N stage, smoking, alcohol use, or gender（P>0.05）. Cox analysis identified surgical margins>2 mm as a significant factor improving PFS（HR=0.14, 95%CI 0.02-0.90, P=0.038）. Conclusion:This systematic analysis suggests setting a 2 mm and longer as clear surgical margin for TORS. Margins>2 mm are associated with superior postoperative PFS rate and prolonged PFS time in HPV-positive oropharyngeal carcinoma patients.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Objective To investigate the effects of force on mechanical stability of FLNa-Ig21/αⅡbβ3-CT complex and the regulation mechanism.Methods The FLNa-Ig21/αⅡbβ3-CT crystal structures were taken from the PDB database.The stability of the complexes in a physiological environment as well as the unfolding path and mechanical stability induced by mechanical forces were analyzed using equilibrium and steered molecular dynamics simulations.Results During the equilibration,the survival rate of most salt bridge and hydrogen bonds was below 0.5,and the interactions between FLNa-Ig21 and αⅡbβ3-CT was relatively weak.During stretching at a constant velocity,the complex could withstand a tensile force of 70-380 pN,and its mechanical strength depended on the force-induced dissociation path.Under a constant force of 0-60 pN,the complexes exhibited a slipping-bond trend,and the force increase facilitated the breakage of the R995-D723 salt bridge and the activation of αⅡbβ3 integrin.Conclusions The force-induced allostery of αⅡbβ3-MP enhanced the complex mechanical strength and delayed FLNa-Ig21 dissociation from αⅡbβ3-CT.After breaking through the 20 pN threshold,force positively regulated the activation of αⅡbβ3 integrin.These results provide insights into the molecular mechanism of αⅡbβ3 activation and the development of related targeted drugs.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder, which is manifested by symptoms such as difficulties in social interaction and communication, stereotypical repetitive behaviors, and narrow areas of interests.At present, the intervention methods for ASD mainly include behavioral intervention, pharmacological intervention, physical intervention, exercise intervention, complementary and alternative medicine intervention.With the progress of science and technology and in-depth research, the intervention methods of ASD will develop in the direction of personalized intervention, deep learning technology, gene therapy and neurofeedback technology.These new intervention methods would hopefully improve the treatment effect and the quality of life of patients.

Objective To explore the application effect of volunteer service in the practical teaching of Traditional Chi-nese Pediatrics.Methods In 2023,80 undergraduate interns from the 2021 cohort at Yunnan University of Traditional Chinese Medicine,who were shadowing in the pediatrics department of a traditional Chinese medicine hospital in Yunnan,were randomly selected as research subjects.They were divided into an experimental group and a control group.The experimental group received teaching through a combination of volunteer service and traditional teaching methods,while the control group was taught using tra-ditional classroom methods.Results The experimental group scored significantly higher than the control group in clinical skills assessments,Mini-CEX scores,subject recognition evaluations,and teaching satisfaction,with statistically significant differences(P＜0.05).Conclusion The use of volunteer service in the practical teaching of Traditional Chinese Pediatrics is highly feasi-ble and can significantly enhance students'clinical practice abilities,stimulate their enthusiasm for learning,foster independent thinking,and improve their overall clinical competencies.

Objective:To retrospectively analyze the clinical phenotype and pathogenic variants in patients with Progressive myoclonus epilepsy (PME).Methods:Clinical data and results of genetic testing for 11 patients diagnosed with PME at the Department of Neurology, the First Affiliated Hospital of Zhejiang University School of Medicine from June 2017 to December 2022 were collected and analyzed.Results:All of the patients, including 4 males and 7 females, had predominant action myoclonus. Three patients had myoclonus as the initial manifestation, whilst eight were diagnosed through genetic testing, including three cases with NEU1 gene variants, two with EPM2A gene variants (1 was novel), one with MT- TK gene variant, one with ATN1 gene variant, and one with CSTB gene variant. No pathogenic variant was identified in the remaining three cases. Among the eight patients with a genetic diagnosis, three were diagnosed with sialidosis, two with Lafora disease, one with Dentatorubral-pallidoluysian atrophy (DRPLA), one with Unverricht-Lundborg disease (ULD), and one with Myoclonic epilepsy with ragging red fibers (MERRF). Conclusion:Compared with pediatric patients, adult patients with PME represent a distinct subtype with slower progression and milder cognitive impairment.
