1.The Role of Selectins in Ischemia-Reperfusion Injury of Brain
International Journal of Cerebrovascular Diseases 2006;0(11):-
Selectins are a family of adhesion molecules,including P-,L-,E-selectins.The three adhesion molecules all participate in the inflammatory processes of ischemia-reperfusion injury of brain.P-selectin is expressed on activated platelets as well as on endothelial cells.E-selectin is only expressed on endothelial cells.P-and E-selectin mediate the adhesion of the leukocytes,platelets and endothelial cells.L-selectin is mainly expressed on leukocytes and mediates leukocytes rolling contact with microvascular endothelial cells.

Objective To study the methods and effects by using thrombolytic catheter in interventional treatment for patients with acute lower limb arterial thrombosis or embolism. Methods One hundred and twelve patients suffered acute lower limb arterial thrombosis or embolism. There were 85 cases of acute lower limb arterial embolism induced by atrial fibrillation in coronary or rheumatic heart disease,other 27 cases of arterial thrombosis caused by different reasons. Interventional treatment by inlying thrombolytic catheter was applied and continuous perfusion was received locally in all patients. Results Complete recanalization was got in 77 cases (68.8%) of 112 cases. Partial re canalization was got in 23 cases (20.5%), and ischemia limbs were saved in spite of chronic limb ischemia(chronic spasmodic limb) occurring in the later follow-up. Nine cases (8.0%) were amputated as a result of irreversible limbs necrosis, 3 cases (2.7%) died from acute renal failure resulting from reperfusion injury or recurrent cerebral embolism.Conclusion Interventional treatment by inlying thrombolytic catheter is a safe and effective method with lower amputation rate for acute lower limb arterial thrombosis or embolism in patients.

Objective To determine the safety and efficacy of robotic mitral valvereplacement using da Vinci S system.Methods From August 2008 to April 2011, over 400 cases of robotic cardiac surgery have been completed in Chinese PLA general hospital, in which 20 patients with isolated mitral valve stenosis underwent robotic mitral replacement, including 7 male and 13 female patients with a mean age of (44.7 ±9.8) years (ranging from 32 to 65 years). 16 patients had a NYHA class Ⅰ~Ⅱ heart function and 4 patients were NYHA class Ⅲ. Fifteen patients were concomitant with atiral fibrillation. Surgery approach was achieved through 4 right chest ports with femoral perfusion and Chitwood aortic occlusion. Antegrade cold blood cardioplegia was administered directly via chest for myocardial protection. The transesophageal echocardiography was used intraoperatively to estimate the surgical results. Results All patients had successful valve replacement including mechanical and tissue valve replacement. There was no conversion to a median sternotomy. The mean cardiopulmonary bypass and arrested heart time were(137.1 ±21.9) minutes and (99.3 ±17.4) minutes. Echocardiographic follow-up in all patients revealed no complications. Conclusion Robotic mitral valve replacement is safe and efficacious in the patients with isolated mitral valve disease.

Objective To explore the inhibitory effects of Corilagin on the production of proinflammatory cytokines in microglia induced by radiation. Methods The cytotoxicity of Corilagin was measured by MTT assay. Microglia BV-2 cells were irradiated 0 or 32 Gy after pretreated with Corilagin for 12 hours. Realtime-PCR was used to detect the mRNA levels of inflammatory cytokines, such as IL-1β,TNF-α on several time-points. The content of nitric oxide (NO) was determined with nitrate reductase method. The translocation of NF-κB was measured by Western blot and immunocytochemical stain.Confocal microscopy was used to observe the expression of Iba-1 and Nemo. Results No cytotoxicity was detected on BV-2 cells with 1-10 μg/ml Corilagin. Iba-1 expression in microglia cells was activated by irradiation, the expression levels of inflammatory cytokines, such as IL-1β, TNF-α and NO were also elevated. Whereas, the production of IL-1 β, TNF-α in activated microglia cells was significantly inhibited with 5 μg/mL corilagin ( tIL-1β = 6. 341, tTNF-α = 3.41 1, tNO = 3. 134, P < 0. 05 ). Corilagin significantly inhibited the expression of Nemo and the translocation of NF-κB p65. Conclusion Corilagin could inhibit the activation of irradiated microglia cells and down-regulate the expression of inflammatory cytokines, via inhibition of the NF-κB signaling pathway.
