Their straightforward synthesis, high stability, and versatile applications have made them increasingly prominent in biomedical research. Drug-induced acute liver injury (DIALI) has become a significant contributor to acute liver injury, primarily driven by the excessive release of reactive oxygen species (ROS), the generation of inflammatory factors, and the induction of macrophage polarization, ultimately leading to hepatocyte death. Nanozymes, with their unique ability to scavenge ROS and mitigate inflammation, present a promising therapeutic strategy for DIALI. In this review, we provide an in-depth exploration of the mechanisms underlying DIALI and a comprehensive summary of nanozyme-based therapeutic approaches. This includes nanozymes composed of various metallic and non-metallic elements, targeted delivery systems, and surface modification strategies.

However, gingival bleeding, increased tension of the gingiva, and saliva flushing after tooth preparation might cause difficulties in gingival retraction. The previous materials generally have inadequate mechanical strength, poor hemostasis, and irritating effects. To achieve effective and rapid gingival retraction and hemostasis is a key clinical challenge. This article has described a novel photoresponsive hydrogel based on carboxymethyl chitosan/polyethylene glycol diacrylate (CMCS/PEGDA). CMCS/PEGDA hydrogel injected into the gingival sulcus can rapidly solidify and expand to push away the gingiva under blue light illumination. It possesses excellent rheological properties and mechanical strength, and shows great gingival retraction in the rabbit gingival sulcus. Additionally, CMCS/PEGDA hydrogel can promote clotting, which was verified in the rat tail amputation model. Compared with the control group, the blood loss of CP hydrogel decreased by 59.2%. The hemostatic mechanism of hydrogel is attributed to the concentration of coagulation factors, aggregation of red blood cells, and the activation of the coagulation pathway.
