ABSTRACT
OBJECTIVE@#To evaluate the curative effect of Functional endoscopic sinus surgery (FESS) who suffered with chronic rhinosinusitis by acoustic rhinometry.@*METHOD@#We collected 60 patients who accepted FESS for chronic rhinosinusitis, and calculated the mean minimal cross-sectional area (MCSA), nasal volume (NV), nasal airway resistance (NAR) by acoustic rhinometry within endoscopy to estimate the curative effect of FESS.@*RESULT@#Four weeks after FESS, the patients' ethmoid sinus,maxillary sinus,frontal sinus and sphenoid sinus were clear by endoscopy. Meanwhile, the mean MCSA and NV by acoustic rhinometry were increased, NAR by acoustic rhinometry were descended. There were significant differences between the quantitative levels before and 4 weeks after FESS.@*CONCLUSION@#As the determining methods of nasal function before and after FESS, acoustic rhinometry and endoscopy can be used to comprehensively evluate the curative effect of FESS.

It is confirmed that chronic atrophic gastritis (CAG) caused by Helicobacter pylori is the main cause of gastric precancerous lesions.CAG is also the key determinant in gastric cancer risk assessment,which affects pepsinogen and gastrin-17 secretion.Most of the gastric cancer patients have poor prognosis,and non-invasive tools for gastric cancer screening and diagnosis are lacking.Therefore,the early detection of gastric cancer in order to reduce the disease mortality is necessary.Pepsinogen and gastrin-17 are biomarkers of gastric mucosa and gastric antra.The serological testing for the stomach-specific biomarkers offers the possibility to know preneoplastic gastric mucosal conditions.
