This study aimed to elucidate the characteristics of small airway epithelial dysfunction in patients with IPF and explore novel therapeutic interventions to impede IPF progression by targeting the dysfunctional small airways.

The Intelligence Structures of School-Age Children with Attention Deficit Hyperactivity Disorder: A Multicenter Cross-Sectional Study in China.

Purpose: There is no consensus on whether cognitive measures among attention deficit hyperactivity disorder (ADHD) subtypes exhibit more similarities or differences, and most of them have been conducted on English-speaking subjects, lacking cross-cultural perspectives. The present study was aimed at investigating the intelligence structures of school-age children with ADHD who speak Chinese, using a multicenter and large sample size approach, offering some references for clinicians.

Patients And Methods: 772 children aged 6 to 12 years with ADHD took part in the cross-sectional study.

ECSIT-X4 is Required for Preventing Pressure Overload-Induced Cardiac Hypertrophy via Regulating Mitochondrial STAT3.

Mitochondrial dysfunction is a key factor in exacerbating pressure overload-induced cardiac hypertrophy and is linked to increased morbidity and mortality. ECSIT, a crucial adaptor for inflammation and mitochondrial function, has been reported to express multiple transcripts in various species and tissues, leading to distinct protein isoforms with diverse subcellular localizations and functions. However, whether an unknown ECSIT isoform exists in cardiac cells and its potential role in regulating mitochondrial function and pathological cardiac hypertrophy has remained unclear.

Chirality-Induced Hydroxyapatite Manipulates Enantioselective Bone-Implant Interactions Toward Ameliorative Osteoporotic Osseointegration.

This article tries to review the application of magnetic resonance imaging in the diagnosis and differential diagnosis of Alzheimer's disease.

Histone lactylation-driven YTHDC1 promotes hepatocellular carcinoma progression via lipid metabolism remodeling.

Lipid metabolism reprogramming is critical for the initiation and progression of hepatocellular carcinoma (HCC). However, how the dysregulation of lipid metabolism contributes to HCC development remains largely unknown. Here, we report that the mA reader YTHDC1-mediated epigenetic regulation of the long noncoding RNA NEAT1 activates stearoyl-CoA desaturase (SCD)-associated lipid metabolic processes during HCC progression.

An Oral HS Responsive CuO Nanozyme Platform with Strong ROS/HS Scavenging Capacity for the Treatment of Colitis.

Gallstones, cholecystectomy, and cancer risk: an observational and Mendelian randomization study.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations.

Sequential delivery of IL-10 and icariin using nanoparticle/hydrogel hybrid system for prompting bone defect repair.

The treatment of large bone defects remains challenging due to the lack of spatiotemporal management of the immune microenvironment, inflammation response and bone remodeling. To address these issues, we designed and developed a nanoparticle/hydrogel hybrid system that can achieve the combined and sequential delivery of an anti-inflammatory factor (IL-10) and osteogenic drug (icariin, ICA). A photopolymerizable composite hydrogel was prepared by combining gelatin methacryloyl (GelMA) and heparin-based acrylated hyaluronic acid (HA) hydrogels containing IL-10, and poly(dl-lactide-co-glycolide) (PLGA)-HA nanoparticles loaded with ICA were incorporated into the composite hydrogels.

Different Role of PET-CT Evaluation in Newly Diagnosed Follicular Lymphoma Upon Rituximab-Based Chemotherapy and Chemo-Free Immunotherapy.

Newly diagnosed follicular lymphoma (FL) patients usually received first-line rituximab-based immunochemotherapy (R-chemo). Recently, rituximab plus lenalidomide (R2) emerged as an alternative chemo-free immunotherapy. We performed a comparative analysis of positron emission tomography/computed tomography (PET/CT) in FL undergoing R-chemo or R2.

Construction and validation of a regulatory T cells-based classification of renal cell carcinoma: an integrated bioinformatic analysis and clinical cohort study.

Purpose: Renal cell carcinoma (RCC), exhibiting remarkable heterogeneity, can be highly infiltrated by regulatory T cells (Tregs). However, the relationship between Treg and the heterogeneity of RCC remains to be explored.

The efficacy and safety of anlotinib plus PD-1 inhibitor in locally advanced/metastatic esophageal squamous cell carcinoma (ESCC) patients who progressed on prior immune checkpoint inhibitors (ICIs): a retrospective real-world study (NCT 04984096).

Background: Several studies have shown that combining immune checkpoint inhibitors (ICIs) with antiangiogenic tyrosine kinase inhibitors is effective for solid tumors, including esophageal squamous cell carcinoma (ESCC). However, most of these studies were focused on immunotherapy-naive patients. This retrospective real-world study offers insights into the efficacy and safety of combining anlotinib with ICIs in locally advanced/metastatic ESCC patients who progressed on prior ICI.

Recentering the humeral head does not necessarily improve glenohumeral abduction: A cadaveric biomechanical study.

Purpose: To explore if recentering the humeral head could improve shoulder abduction in shoulders with irreparable massive rotator cuff tears (IMRCTs).

Methods: Nine fresh-frozen cadaveric shoulders were used to simulate the intact condition and IMRCTs as controls. Four 'recenter' interventions were then sequentially applied: subacromial interposition (SI) using 4- and 8-mm spacers and superior capsule reconstruction (SCR) using two- and four-layer fascia lata grafts.

Resensitizing β-Lactams by Reprogramming Purine Metabolism in Small Colony Variant for Osteomyelitis Treatment.

Small colony variant (SCV) is strongly linked to antibiotic resistance and the persistence of osteomyelitis. However, the intrinsic phenotypic instability of SCV has hindered a thorough investigation of its pathogenic mechanisms. In this study, phenotypically stable SCV strains are successfully recovered from clinical specimens, characterized by elevated drug resistance and reduced immunogenicity.

Senescent lung fibroblasts in idiopathic pulmonary fibrosis facilitate non-small cell lung cancer progression by secreting exosomal MMP1.

Lung cancer is a fatal complication of idiopathic pulmonary fibrosis (IPF) with a poor prognosis. Current treatments are insufficient in improving the prognosis of lung cancer patients with comorbid idiopathic pulmonary fibrosis (IPF-LC). Senescent fibroblasts, as stromal cells in the tumor microenvironment, influence tumor progression via exosomes.

Exploring structured molecular landscape from single-cell multi-omics data by an explainable multimodal model.

There is an urgent need to understand the molecular landscape beyond the conventional cellular landscape, maximizing the translational use and generalized interpretation of state-of-the-art single-cell genomic techniques in biological studies.
