Objective To investigate the influencing factors of surgical treatment of patients with laryngeal cancer.It could provide the better way to treat laryngeal cancer.Methods A total of 80 patients with laryngeal cancer from May 2003 to May 2008 in our hospital were studied.All patients were treated by surgery.The effect of surgery would be observed.The influencing factors and the effect of surgery were analyzed by Logistic.Results A total of 80 patients in the 5-year survival rates were 98.75％ (79/80),76.25％ (61/80),and 51.25％ (41/80).Univariate results showed that age,primary site of the tumor,lymph node metastasis,tumor size,tumor node metastasis(TNM) stage,and treatment modality significantly impacted on the prognosis of patients (P ＜0.01).Multivariate Logistic regression analysis showed that the primary site of the tumor,lymph node metastasis,TNM staging and therapy were independent prognostic risk factors with a statistically significant difference(P ＜ 0.05).Conclusions The prognosis of laryngeal cancer is affected by many factors,the primary sites of tumor,TNM staging,lymph node metastasis,and treatment methods were independent prognostic factors.Laryngeal function preservation surgery is an ideal method in the treatment of laryngeal cancer.

Objective: To investigate the epidemiological characteristics of varicella in Yandu District, Yancheng City, Jiangsu Province from 2005 to 2021, so as to provide insights into the improvements of the varicella control strategy. Methods: The data pertaining to cases in Yandu District from 2005 to 2021 were captured from the National Notifiable Diseases Network Reporting System, and the coverage of varicella vaccination in Yandu District from 2016 to 2021 was captured from the Jiangsu Provincial Immunization Planning System. The trends in incidence of varicella were analyzed using annual percent change (APC), the temporal, population and spatial distributions of varicella cases were descriptively analyzed, and the correlation between the cumulative first-dose varicella vaccination rate and incidence of varicella was examined among birth cohorts in Yandu District from 2005 to 2021. Results: Totally 6 144 varicella cases were reported in Yandu District from 2005 to 2021, with annual mean reported incidence of 50.05/105. The incidence of varicella appeared a tendency towards a rise in Yandu District from 2012 to 2018, with APC of 77.97% (t=11.702, P<0.001), and the incidence appeared a tendency towards a decline from 2018 to 2021, with APC of -41.93% (t=-6.911, P<0.001). The incidence of varicella peaked during the period between November and January of the following year (45.95%), and during the period between May and June (20.35%). The mean incidence of varicella was higher among men than among women (54.72/105 vs. 45.00/105; χ2=57.858, P<0.001). The highest incidence of varicella was found among cases at ages of 6 to 9 years (543.78/105), and varicella predominantly occurred among primary school students (38.40%) and pre-school children (31.85%), with high annual mean incidence in the eastern urban areas (74.27/105).The cumulative first-dose varicella vaccination rate negatively correlated with the incidence of varicella among the birth cohorts in Yandu District in 2019 (r=-0.501, P<0.001), 2020 (r=-0.646, P<0.001) and 2021 (r=-0.602, P<0.001). Conclusions The incidence of varicella appeared a tendency towards a rise followed by a reduction in Yandu District from 2005 to 2021, and the incidence of varicella peaked in winter and at the turn from spring to summer, with varicella predominantly found among primary school students and preschool children.

OBJECTIVETo evaluate the clinical effect of submental island flap.

METHODSThe influence of head and neck radiotherapy and neck lymph node metastasis on the flap was analysed. The clinical effect in the near future and longterm of submental island flap for defects repair was evaluated.

RESULTSThirty-eight submental island flap were applied for reconstruction of head and neck defects following cancer ablation between July of 1997 to December of 1999. 16 of these had preoperative radiotherapy at both donor site and receive site, and neck dissections with resection of primary lesions were simultaneously performed in 18 patients. The success rate was 89.5% (34 of 38). All repaired cases had well matched skin with facial surface and excellent texture for intraoral function.

CONCLUSIONSRoutine preoperative radiation does do not influence the success and healing of the flap. For tumor complete resection, appropriate cases should be chosen. We believe this flap is worthwhile in addition to the existing armamentarium of reconstruction options both facially and intraorally.

Objective To discuss the feasibility, safety and validity of the use of ViabahnTM self-expanding covered stent in endovascular repair of peripheral traumatic pseudoaneurysm (TPA). Methods During the period from June 2012 to April 2014, a total of 8 patients with peripheral TPA were admitted to the Department of Vascular and Endovascular Surgery of Shanghai Changzheng Hospital . The clinical data were retrospective analyzed. The lesions were located at the common carotid artery (n=4), vertebral artery (n=1), subclavian artery (n=1) and superficial femoral artery (n=2). On the basis of acute and chronic TPA classification and different therapeutic principles, endovascular repair with ViabahnTM self-expanding covered stent was employed in 8 patients. Intraoperative angiographic findings, the size and number of the implanted stent, and the immediate angiographic results after stent implantation were recorded. All the patients were followed up to evaluate the improvement of the symptoms, the effectiveness of the repair of TPA cavity, and the occurrence of endoleak or restenosis. Results Successful implantation of ViabahnTM self-expanding covered stent was accomplished in all 8 patients, with a technical success rate of 100%. Angiography performed immediately after stent implantation showed that complete repair of TPA cavity was obtained in all patients, the distal segment of the parent artery was patent, and no endoleak was observed. The sizes of the stent used in the patients were 8×50 mm (n=2) and 9×50 mm (n=2) in common carotid artery, 6×50 mm (n=1) in vertebral artery, 11×100 mm (n=1) in subclavian artery, and 8×100 mm (n=2) in superficial femoral artery. The patients were followed up for 6-30 months (mean of 14.3 months), and the clinical symptoms disappeared in all patients. CT angiography indicated that there was no endoleak or restenosis. Conclusion Based on the different therapeutic principles, the use of ViabahnTM self-expanding covered stent in endovascular repair of peripheral TPA is technically simple and micro-invasive, and clinically feasible with reliable effect and safety. Therefore, this technique can be employed as a first-line therapy option for peripheral TPA.
