PURPOSE: Benign central airway stenosis caused by a variety of reasons and has a high recurrence rate. The recurrence may associated with excessive epithelio-scarring which means a wrong wound-healing way. Cryotherapy is an important technology in interventional pulmonology. Some research shows that cryotherapy may affect the tissue's wound-healing. VEGF is a grow factor taking part in the wound-healing. This study is try to tell the role of VEGF in airway wound-healing and find the relationship between cryotherapy and the change of VEGF's expression.
