Development of an IL-6- and Th1/Treg-based nomogram for identifying low bone mass in patients with rheumatoid arthritis

ObjectiveThis study aimed to analyze clinical and immunological characteristics in patients with rheumatoid arthritis (RA) according to bone loss status, integrate traditional risk factors with immune-inflammatory indicators, and construct and validate…

MELD-S prognostic model: development and external validation for 90-day mortality prediction in acute-on-chronic liver failure

Background and objectivesAccurate prognostic assessment of acute-on-chronic liver failure (ACLF) remains a major clinical challenge. Existing models, such as the Model for End-Stage Liver Disease (MELD), rely solely on clinical indicators and do not in…

SPP1 promotes anoikis resistance and metastatic phenotypes in hepatocellular carcinoma through PI3K-sensitive signaling

BackgroundAnoikis resistance enables tumor cells detached from the extracellular matrix to survive during metastatic dissemination, yet its relationship with the immune microenvironment of hepatocellular carcinoma (HCC) remains incompletely understood….

Overcoming primary non-response to infliximab in ulcerative colitis: monocyte-derived PTGS2 as a therapeutic target

BackgroundPrimary non-response (PNR) to infliximab (IFX) remains a major therapeutic challenge in ulcerative colitis (UC). However, the molecular mechanisms underlying this treatment failure remains unelucidated. Therefore, there is an urgent need to i…

Extracapsular and joint-dominant hand and wrist MRI patterns in psoriatic and rheumatoid arthritis: an exploratory case-control study

BackgroundPsoriatic arthritis (PsA) and rheumatoid arthritis (RA) may present with overlapping hand and wrist symptoms, while their anatomical patterns of inflammation differ.ObjectiveTo compare prespecified hand and wrist magnetic resonance imaging (M…

Mechanistic investigation of clarithromycin in ulcerative colitis involving Kv1.3 downregulation and modulation of the Th17/Treg balance

IntroductionPresent therapies for ulcerative colitis (UC) frequently encounter challenges due to medication resistance and side effects, underscoring the necessity to discover secure and efficacious therapeutic targets. Clarithromycin (CLA), a macrolid…

Cannabidiol suppresses M2-like macrophage polarization via TRPV4/RhoA/ROCK signaling to alleviate hepatic fibrosis

BackgroundDysregulated buildup of extracellular matrix constitutes a hallmark of hepatic fibrosis, loss of liver architectural integrity, and impaired hepatic functional capacity. Pro-fibrogenic M2-polarized macrophages promote the transdifferentiation…
