Accumulating studies have shown that copper has a detrimental effect in cells, and the cuproptosis-related gene signatures have been constructed as clinical tools to predict prognosis in tumors. However, the heterogeneity of cuproptosis has not been fully investigated in ischemic stroke.Methods: Here, we combined the bulk RNA-seq and single cell-RNA-seq data for stroke to investigate the role of cuproptosis in stroke. ⋯ Our findings revealed cuproptosis-related hub genes, which could provide useful biomarkers in ischemic stroke.

MicroRNA-133a-3p (miR-133a-3p) is a potential gene regulator having an important role in the process of inflammation and lung injury. The present work studied the role of miR-133a-3p in sepsis-mediated acute respiratory distress syndrome (ARDS) and the mechanism involved. ⋯ Down-regulation of miR-133a-3p may exert a protective effect on lung tissue against sepsis-mediated ARDS by up-regulating the levels of SIRT1 via suppressing the inflammatory response and inhibiting the cellular apoptosis in lung tissues.

Acute pancreatitis (AP) is a common inflammatory state characterized by a clinical course that can lead to serious local and extrapancreatic organ malfunction and failure. Interleukins (ILs) are biologically active glycoproteins primarily produced by macrophages and lymphocytes. ⋯ The ways to modulate IL activity to reduce inflammation and improve outcomes in individuals with this condition are under investigation. Drugs that target specific ILs might be developed to mitigate the effects of AP.

Transfusion of red blood cells (RBCs) is not devoid of risks; nor is anemia. The aim of the study was to assess the usefulness of a program designed to improve the appropriateness of RBC transfusions in hospital patients.Methods: We retrospectively analyzed time periods before and after program implementation. ⋯ A simple program may lead to a 3-fold decrease in transfusion rate and a significant increase in the percentage of appropriate RBC transfusions.

Diabetic nephropathy (DN) is a leading cause of kidney failure. Lysozyme (LYZ) is an essential component of innate immunity and exhibits antibacterial properties. However, LYZ has been reported to induce nephropathy, implying a possible association between impaired renal function and lysozyme expression. ⋯ Lysozyme promotes kidney fibrosis via the JAK/STAT3 signaling pathway in diabetic nephropathy, and glucose may promote fibroblast proliferation by promoting LYZ auto-secretion.
