1、Objective Using proteomics technology to detect the different serum protein spectrum of allergic rhinitis 、 nasal polyposis and healthy controls,and lay a foundation to clarify the pathogenesis and treat for allergic

2、rhinitis and nasal polyposis. Methods The differentially expressed proteins were detected by surface enhanced laser desorption ionization-time of flight-mass spectrometry(SELDI-TOF-MS)technology and WCX2 proteinchip, a
