The sequence of biochemical and cellular responses restoring the integrity of the subcutaneous tissue of the skin is termed as wound healing. Inflammatory cytokine suppression and inflammatory transduction cascades are the major targets for wound healing. Formulations for wound healing should promote neovascularization and angiogenic pathways by increasing the expression of vascular endothelial growth factor, fibroblast growth factor, and platelet-derived growth factor. Medication used for wound healing promotes antiinflammatory associated with anti-bacterial action. In order to boost the effectiveness of current medical treatments, the cutting-edge nanotechnology offers many novel therapies. This review summarized and discussed wound healing, types of wounds, natural materials used for wound healing, metallic nanoparticles and current nano drug delivery systems used for wound healing with special emphasis on the angiogenesis role in the healing of wounds.

Traditional Chinese medicine (TCM) provides alternative treatment choices for diabetic wounds. The aim of this study was to evaluate the effects of Angelica dahurica and Rheum officinale (ARE) on diabetic wounds and its underlying action mechanism. A total of 36 healthy male Sprague–Dawley rats were randomly divided into three groups: diabetes mellitus (DM) rats treated with ARE (DM-ARE), DM rats treated with 0.9% saline (DM-NS), and non-DM rats treated with 0.9% saline (NDM-NS). DM was induced by intraperitoneal administration of 40 mg/kg of streptozotocin after a 2-week high-fat diet feeding. After excisional skin wounds and treatments, the remaining wound area (RWA) in each group was measured. The RWA in the DM-NS group (69.60% ± 2.35%) was greater than that in the DM-ARE (55.70% ± 1.85%) and NDM-NS groups (52.50% ± 2.77%) on day 6. Besides, the DM-ARE group showed higher vascular endothelial growth factor (VEGF), higher inducible nitric oxide synthase (iNOs), higher [Formula: see text]-smooth muscle actin ([Formula: see text]-SMA), and lower nuclear factor kappa-light-chain-enhancer of activated B cell (NF-[Formula: see text]B) expression in the wound skin tissue. These results showed that treatment with ARE shifted the recovery pattern of diabetic rats to the pattern of nondiabetic rats, indicating that ARE may improve wound healing in diabetic conditions.

Endothelial Growth Factor

Diabetic foot ulcer (DFU) is a kind of chronic vascular complications in diabetes. Wound healing in DFU is a complex process where reduced proangiogenic growth factor is an important factor. We studied angiogenesis factors which may contribute to the healing of DFU. Twenty five type 2 diabetes patients with acute DFU were treated with hospital standard procedure and closely observed for 1 month. Biopsies from wound edges were subjected to histopathology assessment and immunohistochemical staining of CD34, bFGF and VEGF. All examination was performed two times consecutively. We observed that granulation tissues developed faster at proximal site of the foot. Weak tissue VEGF was expressed before treatment. Interestingly, VEGF expression in epidermis increased significantly after patients received treatment. Increased VEGF is consistent with increased number of CD34 positive endothelial cells. These data suggest that epidermal VEGF is an important angiogenesis factor and may improve healing in acute DFU receiving standard treatment.
