AIM: To investigate the influences of bypass-activated complement and TNF-? on intercellular adhesion molecule 1(ICAM-1) expression in endothelial cells, and polymorphonuclear neutrophil-endothelial cell (PMN-EC) adhesion. METHODS: In vitro, zymosan-activated human serum(ZAHS) and/or TNF-? directly stimulated the HUVECS monolayers. PMN-EC adhesion percentage was measured, and modified whole-cell ELISA was used for measurement of ICAM-1. RESULTS: ZAHS alone resulted in no significant change in the degree of PMN adhesion and the level of ICAM-1. Activation of HUVECS with TNF-? followed by ZAHS stimulation resulted in greater increase in PMN-EC adhesion and ICAM-1 expression, as compared with the activation with TNF-? alone. CONCLUSION: Bypass-activated complement can promote ICAM-1 expression and neutrophil -endothelium adhesion induced by TNF-?, and so it is effective for promoting inflammation.

Objective To discuss the effects of blood purification on the patients with multiple organ dysfunction syndrome. Methods Technique of blood purification was applied to the 22 patients with multiple organ dysfunction syndrome. The patients were presented to the Fushun Central Hospital ,between 2003 to 2006. Liver function,kidney function before treatment and after treatment were observed. Results After ttreatment with blood purification,The liver function,kidney function were ameliorated (P

OBJECTIVETo observe the effect of sesamin (Ses) on pulmonary vascular remodeling in rats with monocrotaline ( MCT)-induced pulmonary hypertension (PH).

METHODTotally 48 male Sprague-Dawley (SD) rats were fed adaptively for one week and then divided into the normal control group, the MCT group, the MCT +Ses (50 mg x kg(-1)) group and the MCT + Ses (100 mg x kg(-1)) group, with 12 rats in each group. The PH rat model was induced through the subcutaneous injection with MCT(60 mg x kg(-1)). After the administration for four weeks, efforts were made to measure the right ventricular systolic pressure( RVSP) and mean pulmonary artery pressure (mPAP) through right jugular vein catheterization, and isolate right ventricle( RV) and left ventricle( LV) +septum (S) and measure their length to calculate RV/ ( LV + S) and ratio of RV to tibial length. Pathologic changes in arterioles were observed by HE staining. Masson's trichrome stain was used to demonstrate changes in collagen deposition of arterioles. The alpha-smooth muscle actin (alpha-SMA) expression in pulmonary arteries was measured by immunohistochemisty. The total antioxidative capacity (T-AOC) and malondialdehyde (MDA) content in pulmonary arteries were determined by the colorimetric method. The protein expressions of collagen I, NOX2 and NOX4 were analyzed by Real-time PCR and Western blot.

RESULTAfter the administration for 4 weeks, Ses could attenuate RVSP and mPAP induced by MCT, RV/ (LV + S) and ratio of RV to Tibial length, alpha-SMA and collagen I expressions and remodeling of pulmonary vessels and right ventricle. Meanwhile, Ses could obviously inhibit the expressions of NOX2, NOX4 and MDA content and increase T-AOC.

CONCLUSIONSesamin could ameliorate pulmonary vascular remodeling induced by monocrotaline in PH rats. Its mechanism may be related to expressions of NOX2 and NOX4 expression and reduction in oxidative stress injury.
