Subjects and specimens
This study was approved by the Ethics Committee of Tongji Hospital and
written informed consents were obtained from all subjects. A total of 78
NP patients and 49 control subjects were recruited in this study. The
diagnosis of NPs was made according to the current
guideline.1 Patients undergoing septoplasty owing to
anatomic variations and without any other inflammatory sinonasal
disorders were enrolled as control subjects. During surgery, polyp
tissues from patients with NPs and inferior turbinate mucosal tissues
from control subjects were collected. Not all samples were included in
every experiment protocol because of limited quantity. More information
