Malignant gliomas are the most common intracranial tumors,with a highly invasive nature and a poor prognosis. The invasion of malignant gliomas is a complicate and consecutive multi-step process that includes adhesion, degradation and migration and involves various factors such as cell adhesion molecules, enzymes, and cytokines. Research on the invasive properties of malignant gliomas will advance our understanding of their underlying biological behavior and improve clinical treatment.

Objective: To study the acute and long-term toxicity of brucea javanica oil subnanoemulsion injections ( BJOSI ) . Methods:The mice were given BJOSI by intravenous injection. The acute toxicity was observed and LD50 in mice was calculated by Bliss method. To observe the long-term toxicological effects, Beagle dogs were injected intravenously BJOSI once a day for 8-week du-ration with the dose of 20, 10 and 6 ml·kg-1 , respectively followed by 3-week recovery period. Results:LD50 of BJOSI in mice was 7. 388 g·kg-1 with 95% confidence limits of 6. 306-8. 656 g·kg-1 . The long term toxicity test showed that all the detected indices were within normal range in all groups, including general state, weight changes,hematological indices,biochemical indices,EEG,organ coefficients, morphological and histological changes, while there was an upward tendency of ALT and Cr in every BJOSI group without dose-effect correlation. The dogs could completely recover in three weeks after the administration. Conclusion:The results suggest that BJOSI has low toxicity,while the pathological changes are reversible, and attention should be paid to the function of liver and kidney.

Objective To develop a new ventricular shape index to evaluate the effects of Dor procedure on left ventricular function and shape. Methods From May 2003 to March 2004, 18 patients with coronary heart disease were divided into three groups according to the preoperative data of the echocardiograph. The data of the cardiac function and the three-dimensional ventricular shape index were analyzed before and after operation. Results There was no death in three groups. The change of the cardiac function and ventricular shape in the normal ventricular group were not apparent. The EF of Dor group increased from 0.43?0.06 preoperatively to 0.54?0.08, (P=0.02) postoperatively. Left ventricular shape becomes more conical after operation than it was before operation (conicity closer to 1). The shape of Dor group changed most significantly among the three groups. Conclusion The Dor procedure can improve the cardiac function and the ventricular shape of the patients with left ventricular aneurysm effectively. The 3D echocardiography promised a potent method to quantify the ventricular shape.

Objective To investigate the safety and effectiveness of sirolimus-eluting stents (SESs, Cypher stents) in the treatment of acute myocardial infarction. Methods Ninety seven SESs were implanted in 78 lesions of 78 patients with acute myocardial infarction. In all the lesions, 20.7% of the target vessel diameter ≤2.5 mm, 26% was in-stent restenosis, 82.3% was total occlusions lesions and 17.7% with degree of stenosis up to 95%. The in-hospital procedural success rate and the incidence of complications were observed. Major adverse cardiac events, restenosis rate and late lumen loss were also observed during follow-up. Results All stents were implanted successfully. There were no remained stenosis and major in-hospital complications. During clinical follow-up of 6-15 months (mean 10?3.6 months), 2 patients had recurrent angina due to in-stent restenosis confirmed by angiography, and required target vessel revascularization. No major adverse cardiac events was found in the other 76 patients, and the mortality was null. Follow up quantitative coronary angiographies were obtained in 64 patients, 9?2.2 months after the procedure. The average late lumen loss were 0.24?0.05 mm at the proximal edge, 0.19?0.03 mm within the stent segment, and 0.10?0.02 mm at the distal edge. The angiographic in-lesion restenosis rate was 3.1% and target vessel revascularization was 2.6%. Conclusion SES may be safe and feasiable for the treatment of acute myocardial infarction through reduction in restenosis and target vessel revascularization at 9 months after intervention.

In this paper, we described that using wistar rat rather than Lewis rat, an animal model ofexperimental autoimmune encephalomyelitis (EAE) was established. 12 out of 17 rats showedtypical clinical syndroms and pathological changes, and also developed significant delayed-typeskin hypersen-sitivity reaction to the pathogenic antigen-homogenate of guinea pig spinal cord.The cytotoxicity assay demonstrated that the T-cells of EAE rats can specifically lyse the braintissue of normal rats with specific release rate of 15.1l?t 2.79% which is positive correlativewith clinical severity of EAE. The T cell vaccine was prepared by activating EAE T-cells withConA and then treating with glutaraldehyde. Normal rats were inoculated with this T cell vac-cine and challenged with pathogenic antigen one week later. The result showed that all seven ratsgot complete resistance to EAE. T cells from vaccinated animals can specifically lyse the EAE Tcells with specific release rate of 9.38?1.68%.These results indicated: (a)wistar rat can be used for EAE animal model; (b)The incidence ofEAE is associa ted with the auto-reactive T cellsof EAE animals; (c)Inocula tion of this T cellvaccines can prevent the development of EAE, and this protective effect is also mediated by Tcells.
