Sepsis is a systemic inflammatory reaction syndrome caused by infections. Acute lung injury (ALI) occurs first and most frequently in patients with sepsis. Gentiopicroside (GPS), which originates mostly from is classified as a secoiridoid glycosides. Terpenoid glycosides have various biological effects, including liver protection, blood glucose and cholesterol level management, and anti-inflammatory and antitumor effects. However, presently, the biochemical foundation and mechanism of the anti-inflammatory effects of GPS in sepsis-induced ALI have not been explained. In the present study, we established a rat model of sepsis ALI induced by cecal ligation and puncture. This enables us to observe the effects of GPS therapy, which significantly reduced the inflammatory response (TNF-, IL-1, and IL-6), nitrogen stress, oxidative stress, and severity of ALI at both the whole animal and molecular levels. In addition, GPS ameliorates LPS-induced ALI via regulation of inflammatory response and cell proptosis in BEAS-2B. This study provides a theoretical basis for treating sepsis-induced ALI with GPS.

Extracorporeal membrane oxygenation (ECMO) is a technique used to support severe cardiopulmonary failure. Its potential life-saving benefits are tempered by the significant risk for acute brain injury (ABI), from both primary pathophysiologic factors and ECMO-related complications through central nervous system cellular injury, blood-brain barrier dysfunction (BBB), systemic inflammation and neuroinflammation, and coagulopathy. Plasma biomarkers are an emerging tool used to stratify risk for and diagnose ABI, and prognosticate neurofunctional outcomes.

Fibroblast-like synoviocytes (FLS) are key cells promoting cartilage damage and bone loss in rheumatoid arthritis (RA). They are activated to assume an invasive and migratory phenotype. While mechanisms of FLS activation are unknown, evidence suggests that pre-damaged extracellular matrix (ECM) of the cartilage can trigger FLS activation.

This study investigated the protective effect of arachidonic acid (ARA) against the allograft-induced stress response in Pinctada fucata martensii by characterizing pearl production traits and changes in genes and lipids during postoperative care. Survival and pearl production traits were higher in the ARA treatment group (ARAG) than in the control group (CG). There were 1536 differentially expressed genes (DEGs) in CG-1d vs ARAG-1d and 833 DEGs in CG-3d vs ARAG-3d.

Emamectin benzoate (EMB) is a widely used insecticide that can accumulate in aquatic environments under specific conditions of high application intensity or improper management, posing potential risks to aquatic organisms and human health. This study aimed to evaluate the reproductive toxicity of long-term EMB exposure in zebrafish (Danio rerio) and neurodevelopmental toxicity in their offspring. Zebrafish embryos were exposed to various concentrations of EMB (0, 0.
