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...

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...

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...

Soft-tissue thickness changes following bimaxillary surgery in skeletal class II malocclusion

OBJECTIVES: This retrospective cohort study evaluated regional facial soft-tissue thickness changes after bimaxillary surgery in skeletal Class Ⅱ patients and assessed their associations with skeletal movement and patient-related factors. MATERIALS AND METHODS: Class Ⅱ patients t...

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...

Correlation between clinical communication competence and transition shock among new nurses: a cross-sectional study

New nurses face severe transition shock when entering clinical practice. Clinical communication competence is one of the essential competencies for clinical nurses and is crucial to the quality of nursing care. However, this competence is affected by various factors, and relevant...

Nickase-based suppression of self-ligation in long sticky-end adapters for next-generation sequencing library preparation

The correctness and efficiency of the adapter connection are important factors affecting the quality and yield of the libraries in next-generation sequencing (NGS). Lengthening the sticky ends of the adapters and the targets can effectively improve the efficiency of ligation, how...

Analgesic efficacy of 0.75% ropivacaine versus 2% lidocaine after unilateral mandibular third molar extraction: a prospective observational cohort study

This prospective observational cohort study aimed to evaluate the clinical efficacy of 0.75% ropivacaine in unilateral mandibular third molar extraction and to compare its postoperative analgesic outcomes with those of 2% lidocaine. A total of 128 patients undergoing unilateral m...
