Autologous Platelet-Rich Gel Accelerates Diabetic Wound Healing Through Inhibition of Ferritinophagy.

The objective was to examine the efficacy of autologous platelet-rich gel (APG) in treating diabetic wound and investigate the association between APG and ferritinophagy. A total of 32 patients with diabetic foot (DF) and Wagner grade 1 to 2 were included. Within the APG group, individuals with DF received weekly APG treatment.

Sex differences in symptom network structure of depression, anxiety, and self-efficacy among people with diabetes: a network analysis.

Aims: The present study aims to explore the relations between symptoms of depression and anxiety and self-efficacy among people with diabetes. At the same time, we also examined the sex difference between network structures.

Methods: This study recruited 413 participants with diabetes, and they completed Generalized Anxiety Disorder Scale (GAD-7), Patient Health Questionnaire (PHQ-9), and the Self-efficacy for Diabetes (SED).

Platelet-rich plasma promotes diabetic ulcer repair through inhibition of ferroptosis.

Background: Ferroptosis, a newly discovered form of cell death, can accumulation activates lipid peroxidation and excessive oxidative stress in a high glucose environment. These phenomena suggest there may be ferroptosis pathways in the pathological processes associated with diabetic ulcer (DU). Platelet-rich plasma (PRP) promotes the healing of DU wounds, which may be achieved by the regulation of ferroptosis pathways.

AGEs-induced MMP-9 activation mediated by Notch1 signaling is involved in impaired wound healing in diabetic rats.

Aims: To elucidate the relationship between advanced glycation end products (AGEs), Notch1 signaling, nuclear factor-kappa B (NF-κB), and matrix metalloproteinase-9 (MMP-9) in diabetic wound healing in vitro and in vivo.

Methods: We incubated primary keratinocytes with AGEs alone or AGEs along with γ-secretase inhibitor DAPT, and established diabetic rat wound model by intraperitoneal streptozotocin treatment. The Notch1 signaling components and MMP-9 expression were detected by qPCR, western blotting and gelatin zymography.
