MSCs-PFs in Treating Poorly Healed Wounds of Postoperative Incision Clinical Trial
Official title:
Mesenchymal Stem Cell-derived Pleiotropic Factor in Treating Poorly Healed Wounds of Postoperative Incision
Poor incision healing is a common complication after abdominal surgery, mainly manifested as incision dehiscence, subcutaneous fat liquefaction, malnutrition, and incision infection. Poor healing of the incision will increase the patient's pain and prolong the patient's hospital stay, and the choice of wound treatment is closely related to the wound healing effect. Mesenchymal stem cells mainly rely on paracrine effects to exert their therapeutic effects and obtain better therapeutic effects in wound healing. Here, the pleiotropic factors secreted from mesenchymal stem cells (MSCs-PFs) will be used to treat patients with poor healing after surgery to evaluate its effectiveness and safety.

Inclusion Criteria: 1. Wound size <10X10cm2, the wound base only involves subcutaneous and muscle tissue; 2. Underwent surgical treatment, all incisions were type I, and the incisions healed poorly and delayed healing after 1 week; 3. There is inflammatory reaction at the incision, but no clear indication of infection, or severe infection of the incision.After debridement and dressing change, the infection is controlled and the fresh granulation period is entered 4.

| Primary | Wound healing time and healing rate | Judgment criteria for incision recovery (4 weeks after treatment): Cure: the patient's incision is completely or basically healed, and the surrounding skin returns to normal; markedly effective: the patient's incision is recovered> 1/2, and the surrounding skin returns to normal; effective: the patient's incision is recovered <1 /2, and the surrounding skin returned to normal; invalid: the patient's incision had no obvious changes, and the surrounding skin color had no obvious improvement. | 1 month |
