Core Tip
Core Tip: Fish scale ointment accelerates necrotic cell shedding during wound healing, promotes capillary formation, enhances fibrous tissue and epidermal regeneration, facilitates wound repair, and exhibits anti-infective properties. This study selected the nuclear factor E2-related factor 2 signaling pathway as the target for observation. From the perspective of ferroptosis regulation, it investigated the mechanism by which fish scale ointment promotes diabetic foot ulcer healing in rat models.
