Interventional catheters have been widely applied in diagnostics, therapeutics, and other biomedical areas. The complications caused by catheter-related bacterial infection, venous thrombosis, and vascular abrasion have become the main reasons for the failure of interventional therapy. In this study, polyacrylamide/poly(acrylic acid) lubricating copolymer brushes were constructed on the surface of catheters and efficiently resisted the adhesion of blood components and bacteria through hydration and electrostatic repulsion effects.

Introduction: Trauma and hemorrhagic shock (T/HS) are associated with multiple organ injury. Antithrombin (AT) has anti-inflammatory and organ protective activity through its interaction with endothelial heparan sulfate containing a 3-O-sulfate modification. Our objective was to examine the effects of T/HS on 3-O-sulfated (3-OS) heparan sulfate expression and determine whether AT-heparan sulfate interactions are necessary for its anti-inflammatory properties.

Dietary polysaccharides, recognised as significant natural bioactive compounds, have demonstrated promising potential for the prevention and treatment of cardiovascular disease (CVD). This review provides an overview of the biological properties and classification of polysaccharides, with particular emphasis on their extraction and purification methods. The paper then explores the diverse mechanisms by which polysaccharides exert their effects in CVD, including their antioxidant activity, protection against ischemia-reperfusion injury, anti-apoptotic properties, protection against diabetic cardiomyopathy, anticoagulant and antithrombotic effects, prevention of ventricular remodeling, and protection against vascular injury.
