Résumé
Objective To study the technique and clinical effect of endoscopic surgery using high frequency electrotome with suction device for nasopharyngeal angiofibroma. Methods In this study, we retrospective analyzed the clinical data of 10 patients treated between January 2009 and December 2015. All these patients were treated by endoscopic surgery using high frequency electrotome with suction device. The average blood loss during surgery, tumor residual, recurrent tumor and duration of recovery were evaluated. Results The tumor was completely removed in all 10 patients. The average blood loss was 465 ml, there was no postoperative complication, all patients had no residual tumor, and there was no recurrent tumor over a follow-up of 6~18 months. Conclusion Though it was not preoperative transcatheter arterial embolization, the endoscopic surgery using high frequency electrotome with suction device can be used to treated nasopharyngeal angiofibroma which either limited to nasopharyngeal cavities and paranasal sinus with intraoperative blood pressure control.

Objective To explore the significance of the Self -assessments of Voice Handicap Index (VHI) and The objective detection of Dysphonia Severity Index (DSI) in polyp of vocal cord perioperatively .Methods The Self -assessments of VHI had been completed in 28 patients with polyp of vocal cord before the operation and one week after the operation ,including function(F) ,physiological(P) ,emotion(E) ,and the sum denoted by T .In the meantime ,The DSI had been completed in these patients by acoustic analysis of DIVAS 2 .5 .After one month ,19 pa-tients had been re -examined .Results The DSI value was increasing ,but there was no significant difference be-tween pre-operation and one week after the operation(P>0 .05) ,indicating that the function of vocal cord was not recovered .In VHI scale ,the parameters were significantly different between the time preoperatively and one week postoperatively in F ,E and T(P0 .05) ,indicating that the function of vocal cord was not completely recovered as same as the result of DSI .After one month ,there were significant differences in DSI and VHI ,which showed a full recovery of vocal cord fanction .Conclusion The Self -assessments of VHI and The objective detection of DSI in polyp of vocal cord can evaluate simultaneouly the function of laryngeal .Additionally ,there was a good correlation between the DSI and the VHI score .

Objective:To explore the relationship between the pathophysiological changes in TCM spleen de ciency syndromes and precancerous lesion of gastric mucosa.Method:160 cases with spleen de ciency syndromes accompanied by gastric mucosa intestinal metaplasia,IM and / or atypical hyperplasia,AHP,(spleen de ciency is divided into spleen qi de ciency or SQD,spleen yin de ciency or SyinD and spleen de ciency with qi stagnation or SDQS) and 22 cases in health control group were taken as the study object.The detection was conducted on such trace elements as Zn,Cu of gastric mucosa epithelial cell nuclei and mitochondrion under the direct view of CM200FEG –TEM by adopting 9100/60 -Energy Dispersion X-ray Analyzers;detection was conducted on epithelial cell nucleus DNA by using IBAS2000 image analyzer;detection was conducted on the expression of P53,Ki67,CerbB2,P21ras in gastric mucosa tissue slices by adopting ElivisionTM Plus'.Result:The quantitative changes of gastric mucosa epithelial cell nucleus DNA,Zn,Cu and the positive expression rates of P53,P21ras,CerbB2 and Ki67 increased in the sequence of SQD group,SyinD group and SDQS group,while mitochondrial Cu,Zn decreased in the same sequence,there was signi cant di erence between the groups(P
