Diabetic Ulcers

This clinical trial involves collecting peripheral blood, ulcer tissue, and fecal samples from diabetic ulcer patients for bioinformatics analysis to screen genetic markers significantly associated with ulcer risk and healing differences. Furthermore, multi-omics data will be integrated to establish a diabetic ulcer risk prediction model. Based on key single nucleotide polymorphisms and their regulatory pathways, potential new drug targets for promoting healing will be explored, providing a genetic basis for personalized treatment.
