Objective:To compare the aortic remodeling of the Fabulous stent system and standard thoracic aortic endovascular repair (TEVAR) on distal aorta type B aortic dissection (TBAD). Methods:The prospective data collected between Dec 2017 and Oct 2019 from 134 patients with type B aortic dissection (TBAD) who underwent treatment with the "Fabulous" stent system, and retrospective data from 159 TBAD patients receiving standard TEVAR from corresponding multicenter. By using propensity score matching analysis, we compared the prognosis and aortic remodeling outcomes in patients undergoing Fabulous and standard TEVAR treatments during a 1-year postoperative follow-up.Results:In this study, 62 patients in Fabulous group and 62 patients in standard TEVAR were included.There were no significant statistical differences in baseline characteristics between the two groups. In terms of aortic remodeling in bare stent region, Fabulous group had better change trends of diameter of true lumen [10.6 (4.4, 14.5) mm vs. 4.7 (0.9, 10.7) mm, P=0.001] and false lumen [-24.2 (-30.5, -4.9) mm vs. 0.7 (-11.8, 2.3) mm, P<0.001] than those in the standard TEVAR group. The rate of complete false lumen thrombosis was also higher in the Fabulous group (62.9% vs. 37.1%, P=0.042). Conclusion:The Fabulous stent system, when compared to standard TEVAR surgery, demonstrates good aortic remodeling outcomes in the distal aorta.

Objective·To investigate factors affecting the prognosis of aged esophageal cancer patients after esophagectomy.Methods·Clinical data of 103 aged patients (≥ 80 years old) undergoing esophageetomy were collected.Effects of age,sex,clinical manifestations,pre-operative diseases,post-operative complications,T stage,lymph node metastasis,maximum diameter and location of the tumor,and surgical methods on the post-operative survival were analyzed.Results·1,3,and 5 years survival rates of 103 patients were 63.2％,15.9％,and 2.7％,respectively.Kaplan-Meier survival curve analysis indicated that the post-operative survival was significantly higher in patients with T1 and T2 stages than in patients with T3 stage.The 3 and 5 y survival rates of patients with T 1 stage were 50％ and 25％,respectively.Results of Cox regression multivariate analysis showed that T stage,maximum diameter of tumor,postoperative complications,and lymph node metastasis were independent factors affecting the post-operative survival.Conclusion·Esophageal cancer patients aged over 80 years with smaller tumor diameters,less postoperative complications,and negative lymph node metastasis have a longer post-operative survival period.Esophagectomy for patients with earlier stages (T1 and T2) can achieve an ideal post-operative survival period.

Objective To explore the improving safety measures of colon interposition after esophagectomy .Methods From January 2003 to December 2014, 65 cases of colon interposition after esophagectomy were performed, and some improve-ments were made in the methods and procedures .Mainly including: Preoperative evaluation to first operation; Selection of co-lon segment; Simplify vascular anatomy;Cervical anastomosis was replaced by intrathoracic anastomosis;Modified anastomosis sequence; Strengthen preoperative preparation.Results There were no perioperative deaths.Only 2 patients with cervical fis-tula, due to malnutrition automatically discharged.The rate of anastomotic leakage on neck were 27.77%(10/36) and 6.89%(2/29) in the chest.2 cases were completed intestinal obstruction after jejunostomy , 1 cases of volvulus and 1 cases of intus-susception confirmed by reoperation.Conclusion Colon interposition after esophagectomy is a very important way of surgery. The operation process is complex, but as long as mastering the point of surgery, improving the surgical procedures, the good effect can be obtained and greatly improve the safety of the operation .

Objective Studies show that miRNA plays an important role in regulating the development, metastasis, inva-sion, and angiogenesis of carcinoma.This study aimed to investigate the expression of miR-155-5p in esophageal squamous cell carci-noma ( ESCC) and its role in the occurrence and progression of ESCC. Methods We collected 20 surgical specimens of ESCC and another 20 from the adjacent normal tissue at least 5 cm from the lesion and determined the expression of miR-155-5p in the tissues by qPCR.We transfected the miR-155-5p mimic, inhibitor and negative control plasmid into the Eca109 cells, measured the proliferation and apoptosis of the cells by CCK8 assay and flow cytometry, and examined their migration using the scratch test. Results The ex-pression of miR-155-5p was significantly up-regulated in the ESCC tissue as compared with that in the normal tissue (529.42% vs 100%, P<0.05).The scratch test showed a markedly increased migration of the cancer cells when miR-155-5p was overexpressed. No remarkable differences were observed in the apoptosis rates of the cells transfected with the miR-155-5p mimic ([5.43 ± 3.09]%), inhibitor ([5.28 ±1.98]%), and negative control plasmid ([5.67 ±1.99]%) (P<0.05). Conclusion The ex-pression of miR-155-5p is significantly up-regulated in the ESCC tissue, which may act as a potential maker for the diagnosis of ESCC. The up-regulated expression of miR-155-5p does not significantly in-fluence the proliferation and apoptosis but enhances the migration of Eca109 cells, which may be related to early metastasis of ESCC.

OBJECTIVETo explore the methods and means of surgical treatment for cervical esophageal cancer in order to get the best efficacy.

METHODSRetrospective investigation and analysis were carried out in 137 patients with cervical esophageal cancer undergoing operation in our hospital from January 2005 to December 2013. According to lesion locations, these cases were divided into two groups: larynx preservation group(Group A) and laryngectomy group(Group B). Surgery options of Group A included inversion esophagectomy without thoracotomy, three-incision esophagectomy, end to end anastomosis of cervical esophagus after local resection. Group B included gastric-pharyngeal anastomosis, pharyn-esophagus plasty, colon replacement of the esophagus or jejunal interposition. All the patients received postoperative adjuvant therapy.

RESULTSThere were no perioperative deaths. The main postoperative complications included anastomotic fistula in 20 cases(14.6%), postoperative massive bleeding after inversion esophagectomy in 3 cases, chylothorax in 1 case, anastomotic stenosis in 9 cases, severe gastroesophageal reflux in 6 cases and serious aspiration pneumonia in 2 cases. All these patients had complete resolution of disease with good postoperative quality of life. The 1-year, 3-year and 5-year survival were 73.7%, 48.4% and 26.8% respectively. The most important causes of postoperative death included local recurrence, cervical or mediastinal lymph node metastases, cachexia and multiple organic metastasis.

CONCLUSIONIt is critical to select reasonable methods of operations to reduce postoperative complications and to receive proper adjuvant therapy.

EML4-ALK fusion gene can improve the expression of anaplastic lymphoma kinase (ALK) protein and activate ALK inducing tumor cells proliferation and anti-apoptosis.EMLA-ALK fusion gene in nonsmall-cell lung cancer which has unique clinical and pathological features is more common in young femal,never smokers,and adenocarcinoma patients,At present,EML4-ALK fusion gene can be detected using RT-PCR,FISH and IHC.Crizotinib,an ALK inhibitor,can block the gene's signal pathway and restrain tumor's activity.
