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...

P1.058. 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...

P1.073. 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...

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...

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...

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...

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...

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...

Mefatinib versus gefitinib as a first-line treatment for EGFR-mutated non-small cell lung cancer: a randomized, double-blind, multicenter phase III study

Mefatinib, a novel second-generation epidermal growth factor (EGFR) tyrosine kinase inhibitor that has shown promising antitumor activity in targeting non-small cell lung cancer (NSCLC) with common and uncommon EGFR- activating mutations. In this phase III, randomized, double-bli...

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...

Clinical utility of molecular residual disease detection in early-stage resected EGFR-mutated non-small cell lung cancer

Molecular residual disease (MRD), detected through circulating tumor DNA, has emerged as a promising biomarker for surveillance in patients with early-stage non-small cell lung cancer (NSCLC) following curative-intent resection. Here we report the MRD analysis from the phase 3 EV...

An integrated bioinformatics analysis reveals that targeted activation of IL7R may reduce influenza A virus infection risk in patients with depression

Depression has been associated with increased susceptibility to influenza; however, the underlying mechanisms remain unclear. Mendelian randomization (MR) analysis was performed to assess the causal relationship between depression and influenza. Differential expression genes (DEG...

Pathogenesis of lymphangioleiomyomatosis: from TSC mutations, metabolic reprogramming, to microenvironmental interactions

Lymphangioleiomyomatosis is a rare disease primarily affecting women of reproductive age, characterized by progressive pulmonary cystic destruction and driven by TSC gene loss-induced constitutive mTORC1 activation. Current understanding of the disease extends beyond this primary...

A non-invasive simplified scoring system to predict airway mucus plugs in asthma

Abstract Background Airway mucus plugs are a core pathological feature of severe asthma and are closely associated with airflow limitation and poor prognosis. However, rapid and efficient clinical screening tools for identifying airway mucus plugs in asthma are currently lacking....

A cilia-associated epithelial alteration axis nominates ERICH3 as an entry point to PI3K engagement in lung adenocarcinoma

LUAD adopts heterogeneous oncogenic signalling states, and bias toward a PI3K–AKT–mTOR–engaged state is not fully explained by canonical pathway lesions. Because membrane-proximal spatial organization can tune receptor-proximal signalling yet is difficult to quantify in human tum...
