Abstract Diabetic ulcers are one of the common complications diabetes mellitus and foot is main site diabetic ulcers, which involves small medium-sized arteries, peripheral nerves, microcirculation, etc., with a high rate disability treatment costs. Multidisciplinary treatments spanning medicine material science have been applied for foot, but molecular mechanisms unclear. Bioinformatics was used to evaluate differentially expressed genes when vacuum sealing drainage (VSD) technique histological studies were performed on tissues from six clinical patients before after VSD. Interleukin-6 (IL6) prostaglandin endoperoxide synthase 2 (PTGS2) decreased Epidermal Growth Factor Receptor (EGFR) increased in VSD treatment. Notably, PTGS2 likely facilitates healing by controlling ferroptosis may be both significant prognostic marker potential therapeutic target.

Ferroptosis plays a role in Alzheimer's disease (AD) development. Erigeron breviscapus (Vant.) Hand-Mazz (EBHM) shows promising effects treating cognitive impairment-related diseases. However, the mechanisms by which EBHM regulates ferroptosis AD treatment are not fully understood. This study used bioinformatics, network pharmacology, molecular docking, and dynamics simulation to explore how treatment. The results identified four key genes—HSPA8, GSK3B, CTSB, YWHAG—that involved this regulation, constructed multigene diagnostic model for AD. demonstrated moderate accuracy (area under curve [AUC] = 0.636) distinguishing from non-demented (ND) was further validated with external datasets showing good capabilities (AUC values of 0.898, 0.889, 0.746, 0.712). Additionally, CIBERSORT analysis revealed significant correlation between immune cell infiltration these genes, highlighting their potential immunity. Molecular docking studies indicated that 3,4,5-tricaffeoylquinic acid (TCQA) had highest binding affinity HSPA8, suggesting TCQA HSPA8 components core targets EBHM's regulation therapy. simulations confirmed stability strong TCQA-HSPA8 complex. These findings enhance our understanding underlying may offer new avenues developing effective treatments.
