Effects of MSCs Derived Pleiotropic Factors on Wound Healing in Endonasal Surgeries

Study Overview
=================
Brief Summary
-----------------
Nasal trauma, deviated nasal septum, sinusitis, nasal polyps and other nasal benign diseases are common clinical diseases and require endoscopic sinus surgery. The proper application of the surgical procedure as well as ensuring high quality of wound healing, is also important to achieve successful results in endoscopic sinus surgery. If good quality wound healing cannot be achieved in the surgical field,synechiae and anatomic defects can occur that may require revision surgeries. Mesenchymal stem cells play an active role in the treatment of many diseases. it primarily exerts therapeutic effects through paracrine. In this study, the effect of mesenchymal stem cell-derived multipotent factors on mucosal repair after nasal surgery was evaluated.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Wound healing evaluation | Lund-Kennedy scoring method；under video nasal endoscopy. Including five aspects of polyps, edema, rhinorrhea, scars, and scabs, each score is 0-2 points. Polyp: 0 points means no polyps, 1 point means polyps only in the middle nasal passage, 2 points means polyps beyond the middle nasal passage. Edema: 0 points means no edema, 1 point means mild edema, 2 points means severe edema. Rhinorrhea: 0 points means no rhinorrhea, 1 point means clear and thin nose, 2 points means rhinorrhea is sticky and purulent. Scar: 0 points means no scars, 1 points means mild scars, 2 points means severe scars. Scab formation: 0 points means no scab formation, 1 point means mild scab formation, and 2 points means severe scab formation. Each side 0-10 points, a total of 20 points, the lower the score indicates that the patient's symptoms are lighter. | 2 months |
