Résumé
Objective To explore the role of case based learning (CBL)on Otolaryngology-Head and Neck Surgery teaching. Methods First, correct and high-quailty teaching case was selected. Then, reasonable and precise question was edited. All students needed to prepare their lessons before class and were encouraged to ask question or answer question. And some warnings should be noticed. Result After CBL being implemented, the students received higher clinical grades and more clinical skills. They were more likely to retain their initial interest in or switch their preference to careers in otolaryngology. The supervisor highly appreciated our teaching. Conclusion CBL is feasible in Otolaryngology-Head and Neck Surgery teaching and it should be applied more in future.
Résumé
Objective In order to improve the medical education on otolaryngology,a teaching innovation was implemented.Methods Teaching model was innovated,which included redesigning teaching plan,augmenting study activeness,establishing a teaching system to raise clinic and creative ability.A series of teaching innovation methods was used including optimizing the theoretical and clinic course,adding case course and discussing course,combining lecture and discuss and traditional and modern teaching methods.Results After the teaching innovation being implemented,the students received higher clinical grades and more clinical skills.They were more likely to retain their initial interest in or switch their preference to careers in otolaryngology.The supervisor highly appreciated our teaching.Conclusion The teaching innovation is successful and it's a good reference for deepening teaching reform in future.
Résumé
Objective To investigate the possible pathogenic mechanisms of narrow pharynx in obstructive sleep apnea syndrome (OSAS) induced by neurogenic inflammation Methods The levels of nitric oxide (NO) and calcitonin gene related peptide (CGRP) in fasting plasma and pharyngeal soft tissue homogenate from mild, moderate, and severe OSAS patients, the normal controls, and patients undergoing uvulopalatopharyngoplasty (UPPP) were detected by immunoradioassay and enzyme reduction Results Plasma NO level in serious OSAS patients was the lowest in the five groups and that in the control group was the highest [severe OSAS=(53 33?7 83) mmol/L, controls=(74 30?6 40) mmol/L, UPPP group=(68 12?7 46) mmol/L, moderate OSAS=(60 45?7 51) mmol/L, mild OSAS=(69 24?6 32) mmol/L, P 0 05) [severe OSAS =(44 18?5 80) mmol/L, moderate OSAS=(48 04?6 66), mild OSAS=(50 72?5 33) mmol/L, controls =(54 37?4 43) mmol/L, UPPP group =(54 10?3 70) mmol/L] NO level in pharyngeal tissue of OSAS increased significantly [OSAS =(0 748?0 053) ?mol/g, controls=(0 382?0 031) ?mol/g, P
