Curcumin has the potential to treat inflammatory diseases. This study investigated its effect on sepsis-induced acute lung injury (ALI) in a rat model. 125 healthy rats were randomly divided into five groups, including normal group, sham-operated group, sepsis group, dimethyl sulfoxide group, and curcumin-treated group (25 rats in each subgroup). Sepsis-induced acute lung injury was affected by cecal ligation and puncture surgery. At 0, 6, 12, 24, and 48 h after treatment, the lungs were harvested for histological and protein expression examinations. 24h after the initial treatment, real-time PCR and Western blot analysis showed that the expression of TGF-β1 and SMAD3-dependent signaling pathway was significantly decreased in the curcumin-treated group than other control groups (P<0.05). Therefore, curcumin played a protective role in sepsis-induced ALI, possibly through the inhibition of the expression of TGF-β1/SMAD3 pathway which may provide a new strategy for the treatment of sepsis-induced ALI.

The anti-inflammatory role of miR-23b-3p (miR-23b) is known in autoimmune diseases like multiple sclerosis, systemic lupus erythematosus, and rheumatoid arthritis. However, its role in sepsis-related acute lung injury (ALI) and its effect on macrophages in ALI remain unexplored. This investigation aimed to evaluate miR-23b's therapeutic potential in macrophages in the context of ALI.

This study aimed to investigate the role of circular RNAs (circRNAs) in sepsis-induced acute gastrointestinal injury (AGI), focusing on their potential as biomarkers and their involvement in disease progression. Peripheral blood samples from 14 patients with sepsis-induced AGI and healthy volunteers were collected. RNA sequencing was performed to profile circRNA and miRNA expression.

Sepsis-induced acute kidney injury (SI-AKI) is the most common organ dysfunction of sepsis, characterized with prolonged hospitalization periods and significantly elevated mortality rates. Piplartine (PLG), an alkaloid extracted from Piper longum within the Piperaceae family, has exhibited diverse pharmacological activities, including anti-inflammatory, anti-atherosclerotic, and anti-tumor effects. Herein, we investigated whether the PLG could reverse SI-AKI and explore its possible anti-inflammatory mechanisms.

Rationale: Acute kidney injury (AKI) is a clinical syndrome associated with a multitude of conditions. Although renal replacement therapy (RRT) remains the cornerstone of treatment for advanced AKI, its implementation can potentially pose risks and may not be readily accessible across all healthcare settings and regions. Elevated lactate levels are implicated in sepsis-induced AKI; however, it remains unclear whether increased lactate directly induces AKI or elucidates the underlying mechanisms.
