Background: Plasma is commonly used in patients with coagulopathy; however, its role in patients with sepsis-induced coagulopathy (SIC) is unclear. This study aimed to evaluate the effect of plasma transfusion on the prognosis of patients with SIC. Methods: Data were collected from the Medical Information Mart for Intensive Care IV database. ⋯ The restricted cubic spline analysis indicated that increased plasma transfusion was associated with increased in-hospital mortality in patients with SIC. Conclusion: Plasma transfusion increases in-hospital mortality in patients with SIC, and the mortality rate increases with the amount of plasma transfusion. Patients with SIC who received early plasma infusion had lower in-hospital mortality than those who received no early plasma transfusion.

Background: Sepsis-associated acute lung injury (SA-ALI) is a serious threat to human health. A growing body of evidence suggested that circular RNAs may be involved in ALI progression. The aim of this study was to investigate the effect and mechanism of circ_0001226 on lipopolysaccharide (LPS)-induced BEAS-2B cells. ⋯ Besides that, circ_0001226 interference contributed to cell proliferation and restrained apoptosis and inflammation in LPS-induced BEAS-2B cells. Mechanically, circ_0001226 worked as a molecular sponge of miR-940 to regulate TGFBR2 expression. Conclusion: Circ_0001226 deficiency weakened LPS-mediated proliferation inhibition and inflammatory processes in BEAS-2B cells by binding miR-940 and regulating TGFBR2.

Cardiac macrophages with different polarization phenotypes regulate ventricular remodeling and neovascularization after myocardial infarction (MI). Annexin A2 (ANXA2) promotes macrophage polarization to the repair phenotype and regulates neovascularization. However, whether ANXA2 plays any role in post-MI remodeling and its underlying mechanism remains obscure. ⋯ In addition, ANXA2 directly interacted with integrin β3 in CMECs and enhanced their growth, migration, and tubule formation. Our results indicate that increased expression of ANXA2 could confer protection against MI-induced injury by promoting neovascularization in the infarcted area, partly through the inhibition of YAP in macrophages and activation of integrin β3 in endothelial cells. Our study provides new therapeutic strategies for the treatment of MI injury.
