Objective To investigate the factors influencing the survival time of patients with recurrent glioma after reoperation.Methods 45 cases in our hospital due to recurrence cerebral glioma undergoing reoperation were selected, whose general data were retrospective analyzed, and the surgery conditions, postoperative complications, survival time and its influencing factors were analyzed.Results In 45 cases of recurrent cerebral glioma patients undergoing surgical treatment, 25 cases with total resection, 20 cases with subtotal resection, 3 cases with postoperative brain edema, 3 cases with pulmonary infection; and compared with pre-surgery, the Karnovsky performance status (KPS) score increased significantly (P <0.05); and postoperative survival time was ( 10.62 ±3.25 ) months, multi-factor regression analysis showed that recurrence lesion resection, preoperative KPS score, recurrent interval time and preoperative grading is the independent risk factors related to survival time(P<0.05).Conclusion Surgical treatment of recurrent cerebral glioma is of great significance, and aggressive surgical treatment could improve the quality of life, prolong the survival time and improve the quality of life.

Objective:To investigate the efficacy of double balloon enteroscopy (DBE) in the treatment of bleeding from small intestinal vascular lesion and risk factors of bleeding recurrence .Methods:From April 2013 to May 2020, at Air Force Medical Center, the clinical data of 65 patients with confirmed or suspected bleeding from small intestinal vascular lesion were retrospectively analyzed. The patients were divided into DBE treatment group (patients of Yano classification 1a and 1b received argon plasma coagulation, and patients of Yano classification 2 and 3 accepted combination of titanium clip and submucosal injection of lauromacrogol sclerosing agent) and non-DBE treatment group (traditional treatments such as stopping anticoagulant or antiplatelet drugs, blood transfusion, and iron supplementation). The bleeding recurrence of patients with single small intestinal vascular lesion between DBE treatment group and non-DBE treatment group, and patients with single or mulitiple vascular lesion of DBE treatment group were compared. Univariate analysis was used to analyze the clinical data of patients with or without recurrent bleeding. Multivariate logistic regression model was used to analyze the independent risk factors and protective factors of recurrent bleeding in small intestinal vascular lesion. Independent sample t test, chi-square test and Fisher exact probability method were used for statistical analysis. Results:Forty-four (25 of single vascular lesion and 19 of multiple vascular lesion) patients were diagnosed with small intestinal vascular lesions and received DBE treatment (DBE treatment group). Twenty-one patients with single vascular lesion accepted traditional treatment (non-DBE treatment group). The recurrent rate of bleeding in patients with single vascular lesion of DBE treatment group was lower than that in patients with single vascular lesion of non-DBE treatment group and patients with multiple vascular lesion of DBE treatment group (24.0%, 6/25 vs. 71.4%, 15/21 and 12/19), and the differences were statistically significant ( χ2=10.348 and 6.848, P=0.001 and 0.009). The results of univariate analysis showed that the proportion of blood transfusion, hypertension, complicated with valvular heart disease and DBE treatment in patients with rebleeding or not rebleeding from small intestinal vascular lesion was different with statistically significant (69.7%(23/33) vs. 37.5%(12/32), 51.5%(17/33) vs. 18.8%(6/32), 42.4%(14/33) vs. 12.5%(4/32) and 54.5%(18/33) vs. 81.2%(26/32), χ2=6.777, 7.628, 7.265, and 5.298, all P<0.05). The results of multivariate logistic regression analysis indicated that blood transfusion during the course of disease (odds ratien ( OR)=3.736, 95% confidence interval ( CI) 1.082 to 12.898, P=0.037) and complication with valvular heart disease ( OR=4.916, 95% CI 1.107 to 21.829, P=0.036) were independent risk factors of bleeding recurrence in patients with small intestinal vascular lesions. DBE treatment was the protective factor of bleeding recurrence in patients with small intestinal vascular lesion ( OR=0.214, 95% CI 0.057 to 0.808, P=0.023). Conclusions:DBE is effective in the treatment of small intestinal vascular lesion bleeding, especially for single vascular lesion. Blood transfusion during disease course and complication with valvular heart disease are independent risk factors for bleeding recurrence in patients with small intestinal vascular lesion.

Data of 7 patients with complex benign esophageal strictures (CBESs) who underwent endoscopic longitudinal incision combined with local injection of bleomycin were retrospectively reviewed at Air Force Medical Center from August 2018 to November 2019.The length of preoperative esophageal stenosis was 4-14 cm and the minimum diameter of esophageal stenosis was 0.2-0.4 cm in 7 cases. The procedure was successful for all 7 patients.No adverse events occurred during 5-14 months of follow-up period.Restenosis and dysphagia occurred in 5 cases.The interval between the first endoscopic treatment and the recurrence of esophageal stenosis was 30-120 days.Among the 5 cases of recurrence, 4 cases remained unobstructed after 2 treatments and 1 case remained unobstructed after 4 treatments. The dysphagia scores of 7 patients were graded from 0 to 1 by the end of follow-up. Endoscopic longitudinal incision combined with bleomycin therapy in treatment of CBESs is safe and effective.
