ABSTRACT
OBJECTIVE:To investigate the effects of Melilotus extract tablet on postoperative therapeutic efficacy of chronic sinusitis endoscopic surgery and the recovery of nasal mucosa. METHODS:The clinical data of 100 patients undergoing chronic si-nusitis functional endoscopic surgery in our hospital from May 2015 to Oct. 2016 were analyzed retrospectively and they were divid-ed into control group and observation group according to postoperative treatment,with 50 cases in each group. Two groups received anti-inflammatory,anti-histamine and hemostasis therapy. The control group received Eucalyptol,linonene and pinene enteric soft capsules 0.3 g,tid;observation group was additionally given Melilotus extract tablet 1.2 g,tid,for 6 weeks,on the basis of con-trol group. VAS and Lund-Kennedy endoscopic score were compared between 2 groups before and after treatment. Clinical effica-cies and the occurrence of ADR were also compared between 2 groups. RESULTS:there was no statistical significance in VAS score and its total score,Lund-Kennedy endoscopic score and its total score between 2 groups before treatment (P>0.05). After treatment,VAS score and its total score,Lund-Kennedy endoscopic score and its total score of 2 groups were significantly de-creased,and the observation group was significantly lower than the control group,with statistical significance(P0.05). CONCLU-SIONS:Melilotus extract tablet helps to improve clinical efficacy and the recovery of nasal mucosa in patients with chronic sinus-itis after endoscopic surgery,with good safety.
ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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
