Aim:To study whether urotensin II（UII）,a potent vasoconstrictive peptide,isinvolved in the development of cardiac hypertrophy and fibrogenesis of ratsinduced by isoproterenol（ISO）.Methods:Thirty male Wistar rats were randomlydivided into 3 *** 1 was the healthy control group,group 2 was the ISOgroup,and group 3 was the ISO+UII *** groups 2 and 3,ISO(5 mg-kg-1.d-1)wasgiven（sc）once daily for 7 *** 3 was also given UII in the first day [3 nmol/kg（5μg/kg）,iv],followed by sc（1.5 μg/kg）twice *** 1 received 0.9% *** receptor（UT）mRNA expression was determined by *** contents ofUII and angiotensin II（Ang II）were determined by *** vitro,the effects of UII on DNA/collagen synthesis of cardiac fibroblasts were deter-mined by [3H]thymidine/[3H]proline ***:The ratio of heartweight/body weight,plasma lactate dehydrogenase activity,myocardialmalondialdehyde and hydroxyproline concentration increased significantly in theISO group,as well as UT mRNA expression,plasma and cardiac UII and ventricu-lar Ang II,compared with the control group（P<0.01）.ISO induced significantmyocardial ***,UII+ISO co-treatment significantly increasedthe changes of biochemical markers of injury and the degree of cardiac hypertro-phy and *** vitro,5×10～9-5×10-7mol/L UII stimulated[3H]thymidine/[3H]proline incorporation into cardiac fibroblasts in a dose-dependent manner（P<0.01）.Conclusion:These results suggest that UII was involved in the development ofcardiac fibrosis and hypertrophy by synergistic effects with ISO.

作者： Qi Zhao hebei university of engineering Handan hebei China Yanliao Tan hebei university of engineering Handan hebei China

Quality evaluation becomes more and more important in Web Service life cycle on Service Selection, real-time monitoring, management, accounting and other stages. And fuzzy theory has been applied to this field. In this paper, the algorithm of fuzzy comprehensive evaluation is ameliorated on differentiating redundancy membership degree. It eliminates redundant data in membership degrees of index which are useless for objective classification. Then it realizes the conversion of membership degrees without redundant data. It can be used in the evaluation on the QoS of Web Service.

作者： QU Zhiming School of Civil engineering hebei university of engineering Handan hebei Province 056038 China

In recent years, much research has been devoted to the visualization of redundancy. Contrarily, few have enabled the development of agents. In fact, few statisticians would disagree with the analysis of Smalltalk, which embodies the typical principles of theory. Through experiments and results analysis, it is concluded that new signed information is proposed, which proves to be practicable on emulating expert system based on agents development.
