P1.058. Angiotensin System Inhibitors and Outcomes After Neoadjuvant Therapy for Locally Advanced ESCC

Abstract Topic Esophageal Cancer: Adjuvant and Neo-Adjuvant Therapies Background Renin angiotensin system signaling has been implicated in tumor growth, angiogenesis, immune modulation, and responses to cytotoxic and radiation-based therapies, yet clinical effects appear heteroge...

P1.057. Early Recurrence After Neoadjuvant Therapy and Esophagectomy for Locally Advanced ESCC

Abstract Topic Esophageal Cancer: Adjuvant and Neo-Adjuvant Therapies Background Despite improved interventions with radical esophagectomy accompanied by perioperative systematic therapy, recurrence remains frequent in locally advanced esophageal squamous cell carcinoma (ESCC). A...

Epithelial–mesenchymal transition in carcinoma: navigating phenotypic states to target resistance and metastasis

Epithelial–mesenchymal transition (EMT), historically described as a binary morphological change from an epithelium to a mesenchymal state, no longer adequately accounts for carcinoma cell phenotypes observed in patients. Single-cell sequencing, spatial-omics, and lineage tracing...

P1.059. Calcium-Channel Blocker Use and Survival After Neoadjuvant Therapy for Locally Advanced ESCC

Abstract Topic Esophageal Cancer: Adjuvant and Neo-Adjuvant Therapies Background Calcium-channel blockers (CCBs) are commonly prescribed for cardiovascular disease. Beyond hemodynamic effects, experimental studies suggest that CCBs may modulate tumor biology through interference...

P1.073. The Evaluative Value of Quality of Life in Neoadjuvant Treatment for Esophageal Squamous Cell Carcinoma

Abstract Topic Esophageal Cancer: Adjuvant and Neo-Adjuvant Therapies Background While neoadjuvant therapy contribute to tumor downstaging and improves resectability rates, effective tools for predicting treatment response remain limited. This study investigated quality of life b...

Machine Learning‐Triggered Auto‐Discovery and Promotion of Luminescent Materials: From Predictive Modeling to Autonomous Laboratories

ABSTRACT Machine learning (ML) is transforming the development of luminescent materials, including quantum dots, rare‐earth‐doped phosphors, and transition‐metal‐doped phosphors, by addressing the limitations inherent in traditional trial‐and‐error methodologies. First‐generation...

Benzo[a]pyrene-induced METTL3 overexpression accelerates renal cell carcinoma progression via m6A modification of LTB4R mRNA and enhanced Treg infiltration

Benzo[ a ]pyrene (BaP) is a widespread environmental pollutant and a representative polycyclic aromatic hydrocarbon with well-established carcinogenic properties. However, the molecular mechanisms through which BaP promotes renal cell carcinoma (RCC) progression, particularly tho...

Motor imagery enhances swallowing motor cortex excitability and activates sensorimotor regions: a TMS and fNIRS study

Action observation (AO) and motor imagery (MI) represent promising, non-invasive strategies for promoting neuroplasticity in motor rehabilitation by engaging the shared neural substrates of actual movement. However, their translation to swallowing rehabilitation, particularly for...

Blocking AGEs reduces airway epithelial viral susceptibility in diabetes-exacerbated COPD

Abstract Although diabetic complications are well-established in multiple organs, their impact on the respiratory system remains unclear. Clinical evidence indicates accelerated chronic obstructive pulmonary disease (COPD) progression in individuals with diabetes, yet the underly...

A Biofabricated Human Acinus‐on‐a‐Chip Unveils Mechanotransductive Drivers of Ventilator‐Induced Lung Injury via Decoupling Volutrauma and Barotrauma

Ventilator-induced lung injury (VILI), an iatrogenic complication of mechanical ventilation, remains poorly understood due to the absence of physiologically relevant in vitro models, impeding targeted therapy development. Here, we engineer a bioinspired acinus-on-a-chip model rec...

Single-cell transcriptomics and functional validation reveal a TUBB4B-associated malignant epithelial state in nasopharyngeal carcinoma

Intratumoral heterogeneity of malignant epithelial cells limits prognostic stratification and therapeutic development in NPC, yet transcriptionally distinct malignant epithelial states and their associated molecular programs remain poorly characterized. We aimed to identify clini...

Palliative care knowledge and attitudes toward end-of-life care among clinical nurses across healthcare settings in Guangzhou, China: a cross-sectional study

Despite growing global recognition of palliative care’s importance, access to adequately trained professionals and high-quality services remains highly unequal across countries. Nurses’ knowledge and attitudes are critical determinants of end-of-life care quality, yet evidence fr...

YAP delactylation enhances therapy resistance in renal cell carcinoma

Abstract Lactylation is a novel lysine acylation modification, and its function and exact mechanisms remain unclear. The responsiveness to combined targeted and immunotherapy continues to be a major challenge in cancer treatment. Here, we discovered that lysine lactylation (Kla)...

Development of a urine-based DNA methylation assay for early endometrial cancer detection: a multicenter diagnostic study

Endometrial cancer (EC) incidence is rising globally, yet diagnosis still depends on invasive procedures, which limit accessibility and delay early detection. A noninvasive, accurate, and accessible diagnostic assay is urgently needed to enable early EC detection. In this multice...

Severe abdominal aortic calcification is associated with poor two‑year outcomes after posterior lumbar interbody fusion in osteoporotic patients: a retrospective cohort study

To investigate whether preoperative abdominal aortic calcification (AAC) severity assessed on lateral lumbar radiographs is associated with 2year clinical and radiographic outcomes in osteoporotic patients who have undergone posterior lumbar interbody fusion (PLIF) for the treatm...

Association between calling and work engagement, and the mediating role of psychological capital and organizational commitment: a structural equation modeling study in China

Abstract Purpose This research aimed to examine the association between calling and work engagement, as well as the mediating roles of psychological capital and organizational commitment. The findings may inform the development of targeted interventions to enhance work engagement...

Procalcitonin for diagnosing infected pancreatic necrosis: a systematic review and meta-analysis

Abstract Background Infected pancreatic necrosis (IPN) ranks among the most severe local complications of acute pancreatitis (AP) and plays a central role in driving AP-related death. Procalcitonin (PCT), a serum biomarker that responds preferentially to bacterial infection, has...

Ambient nitrogen dioxide and composition-specific risk of urolithiasis: a multicenter time-stratified case-crossover study

Background: Emerging evidence suggests that ambient air pollution and meteorological variation may trigger urolithiasis, but stone-composition–specific and lagged associations are poorly characterized.Methods: We conducted a multicenter, time-stratified case-crossover study in Gu...
