ABSTRACT
Objective To study safety and efficacy of transurethral Thulium laser resection of high-risk stage bladder tumor in anticoagulant state.Methods A total of 26 non-muscle invasive bladder cancer patients receiving long-term anticoagulant therapy,including 16 cases with cerebral infarction,7 cases with coronary heart disease,3 patients with coronary stenting,were retrospectively analyzed in our hospital from July 2012 to July 2014.In condition not stopping anticoagulants,Thulium laser transurethral resection of bladder tumor was performed,and hemoglobin,thrombin time,the operative time,intraoperative blood loss,postoperative bladder irrigation duration,postoperative hospital stay,bladder tumor recurrence within two years,the postoperative complications were recorded before and after surgery.Results All patients were successfully treated.The operative time was(29.1 ± 12.8) min,int raoperative blood loss was (29.4 ± 16.9) ml portions,postoperative bladder irrigation time was (1.25 ± 0.55) d,postoperative hospital stay was(5.51 ± 1.06) d.Hemoglobin before and after operation were (131.35 ± 6.57) g/L and (129.75 ± 11.05) g/L respectively,there was no statistically significant differences (t =1.014,P ＞ 0.05) between them.Prothrombin time before and after operation were (12.50 ± 0.25) s and(12.44 ± 0.27) s,with no statistically significant difference (t =0.908,P＞0.05)between them.During the followed-up of 48 months,tumor recurred at heterotopia in 2 patients.Conclusions Thulium laser transurethral resection of bladder tumor is safe and effective for patients undergoing long-term oral anticoagulation drugs,without a needto stop taking anticoagulant drugs.
ABSTRACT
Objective To investigate the effect of hypertonic saline on TNF-а, IL-1β, S-100β level following focal cerebral ischemia-reperfusion injury in rats and explore the mechanisms involved. Methods Ninety rats were randomized equally into 4 groups,namely the pseudo-operated group (A group),untreated IR injury group (B group),C group (4.2% hypertonic saline) and D group (7.5% hypertonic saline). Cerebral ischemia was induced by middle cerebral artery occlusion for 2 h followed by administration of the corresponding treatments in group C and D. After 22 h of reperfusion , TNF-а, IL-1β, S-100βexpression in the ischemic brain tissue were measured by enzyme-linked immunosorbent assay (ELISA). Results After hypcrtonic saline treatment, the two saline-treated groups showed significant reduction in TNF-а、IL-1β、S-100β levels , but were still higher than pseudo-operated group(A group). Compared with B group, significant difference can be seen among C and D group. Conclusion Hypcrtonic saline can reduce cerebral TNF-а、IL-1β、S-100βlevel of isehemia-reperfusion injury.
ABSTRACT
Objective To investigate the effect of EGB on SOD, MDA of ventilator-induced lung injury in rats and its possible mechanisms. Methods Thirty male SD rats were randomly divided into 3 groups: control group (C group), high tidal ventilation group (H group) and EGB group (E group). The setting mechanical ventilation was VT=30 mL/kg, RR=40/min, I/E=1/3, PEEP=0 cmH2 O and FiO2=21%. The broncho-alveolar lavage fluid (BLAF) and serum were obtained for determination of the levels of SOD and MDA at the end of 4 h mechanical ventilation. The Lungs were removed, and the wet-to-dry weight ratio (W/D) and pulmonary pathologic changes were measured. Results As compared with C group, W/D and the levels of MDA were significantly increased in H group, but the levels of SOD were reduced in H group. As compared with H group, W/D and the levels of MDA were significantly decreased in E group, but the levels of SOD were increased in E group. Pulmonary pathologic changes were alleviated in E group comparing with H group. Conclusion EGB injection may have a protective role against hyperoxia and induced pulmonary damage in rats.
