Abstract

The invention belongs to the technical field of wound repair, and particularly relates to application of fat emulsion in preparation of a wound repair material. The fat emulsion has a good anti-inflammatory effect in vitro and in vivo, and can significantly down-regulate the expression of proinflammatory cytokines TNF-alpha and IL-1beta; meanwhile, the fat emulsion can also promote angiogenesis and cell migration, acts on various periods of wound healing, and has a remarkable effect of promoting wound healing; the wound repair dressing prepared on the basis of the fat emulsion is applied to a diabetic wound mouse model, the blood vessel density of the wound can be increased, the healing rate of the wound is increased, and tissue epithelization and more collagen deposition formation are promoted.

Description

technical field [0001] The invention belongs to the technical field of wound repair. More specifically, it relates to the application of fat emulsion in the preparation of wound repair materials. Background technique [0002] The skin is the largest organ of the human body and serves as a protective barrier between the inside of the body and the environment. When the skin is damaged due to daily life or other diseases and is not repaired in time, the wound is easily infected and develops into a chronic wound. For example, diabetic foot ulcer (DFU) is a common diabetic syndrome, which is even life-threatening in severe cases. Amputation. [0003] Studies have shown that wound healing mainly includes four periods of hemostasis and coagulation, inflammation, proliferation and tissue remodeling: the hemostasis and coagulation period, platelet activation, and secretion of related factors produce a series of cascade reactions, which promote blood coagulation into thrombus and ac...
