Objective To investigate the expression of Notch4 protein and to analyze its correlation with the clinical parameters and the microvessel dentisty in renal cell carcinoma. Methods The expression of Notch4 was examined in 60 cases of renal cell carcinoma and the para-carcinoma tissue by SP immunohistochemical stain-ing ,and CD34 detection was used for counting microvessel density. Statistical analysis was performed to reveal the correlation with clinicopathological parameters ,microvessel density and prognosis. Results The positive rate of Notch4 protein expression was 75%(45/60)in para-carcinoma tissue,and was 43.3%(26/60)in renal cell car-cinoma,with significant difference on tumor grade and Lymph node metastasis(P<0.05). The microvessel densi-ty in Notch4 positive tissues was significant lower than that in the negative samples(P<0.05). The survival time of patients with Notch4 positive expression was significantly longer than that of patients with Notch4 negative expres-sion(P<0.05). Conclusion Notch4 protein plays an important role in the development of renal cell carcinoma. Notch4 expression might both attenuate the malignant biological characteristics and suppress the angiogenesis dur-ing tumor development.

Objective Extracorporeal membrane oxygenation (ECMO) provides a treatment for patients with acute heart-lung failure. However, as an invasive procedure, it associated with high incidence of complications. It is important to a-vert and reduce the complications for improving the success rate in critically ill patients. We investigate the complications associated with ECMO after cardiac surgery and their management. Methods Clinical data from 117 postoperative patients[32 male, mean age (48.7 ± 16.5) years]supported with ECMO in the cardiovascular intensive care unit( ICU) from March 2005 to June 2008 were analyzed retrospectively. The cardiac operations they had undergone included coronary artery bypass grafting (n = 20), coronary artery bypass grafting and remodeling of left ventricle(n =9), coronary artery bypass grafting and valvular operation(n =5), repair of ventricular septal perforation following acute myocardial infarction(n =2), valvular operation( n = 46), heart/lung transplantation (n = 20/1), correction of congenital heart defects ( n = 10), and aortic operations ( n = 4). Venoarterial bypass was established in 110 patients by cannulation of the right atrium and femoral artery, and that of the right atrium and ascending aorta in 5 cases. Left atrial drainage to ECMO was added in 2 cases. Venovenous bypass was established in 2 patients with hypoxemia following cardiac surgery. Heparin was infused for maintaining the activated coagulation time (ACT) at 160 to 200 seconds for centrifugal pump(114 cases),and 200 to 250 seconds for roller pump(3 cases) to avoid thrombotic events until decannulation was achieved. Results The mean ECMO duration was 61 hours (range 3 to 225 hours). 48(41.0% ) patients died, 18 of them died of complications after weaning from circulatory assistant successfully. Complications occurred in 74 (63.2% ) patients included reoperation for hemostasis (n = 24), renal failure requiring renal replacement therapy (n =29), nosocomial infections ( n = 32) , ischemia in the extremities(n = 5), plasma leakage of oxygenators ( n = 29), gastroenteral hemorrhage ( n = 14), hemolysis ( n = 7 ), neurological complications ( n = 4) and centrifugal pump failure (n =1). Conclusion Bleeding is an early complication associated with ECMO support. The risk of nosocomial infection, renal failure and plasma leakage of oxygenators increases with the duration of ECMO support.

Objective To assess apoptosis mediated by the cell death receptor Fas in peripheral T lymphocytes of patients with abdominal aortic aneurysm. Methods The apoptotic pathway was triggered by anti-Fas monoclonal antibody in cultured and activated peripheral T-cells from 20 AAA patients. Control groups consisted of 15 patients with aortic atherosclerotic occlusive disease(AOD)and 25 healthy individuals. Cell survival and death rate were assessed. Results Cross-linkage of Fas receptor exerted a strong apoptotic response on T cells from AOD patients and healthy controls, while the effect on T cells was very limited from that of AAA patients. The evaluation of cell Survival rate showed a significantly higher percentage in AAA group(98.9%±10.3%)than in the AOD subjects(58.9%±15.2%)or the healthy group(59.4%±12.9%;P<0.001=.Apoptosis assessment by annexin V and propidium iodide staining and flow cytometry showed similar results. The defect in AAA group was not due to decreased fas expressed at normal levels. Moreover,it specifically involved the Fas system because cell death was induced in the normal way by methylprednisolone. Conclusions Fas-induced apoptosis in activated T cell from AAA patients is impaired. This may disturb the normal down-regulation of the immune response and thus provide a new insight into possible mechanisms and routes in the pathogenesis of AAA.
