In vitro study on ribozyme against hepatitis C virus

Objective: To determine the effective nucleotide sites of ribozymes against HCV, and obtain a highly effective, nontoxic and inexpensive antisense ribozyme specific for HCV. Methods: Two effective ribozymes, targeted to HCV 5’NC region and C region, were designed and synthesized. Eukaryotic expression vectors, pSV2-gpt. CD-SR (, containing either HCRZNC or HCRZC were constructued and transfected into MT-2 cells, which had been infected by HCV. Quantitative PCR and hydridization were used to determine the effect of inhibition of HCV by ribozymes. Results: HCRZNC and HCRZC suppressed the replication of HCV by 54.7% and 62.1%, respectively. Furthermore, when both ribozymes were cotransfected into cells, they suppressed replication by 78.8%. Conclusion: Two specific antisense ribozymes have strong inhibitory effects on the replication of HCV in cultured cells, and have better effect when used together.     

传统几何造型艺术在现代服装设计中的立体表现

近年来,富有形式美感的几何造型服装在时装舞台上越加醒目,越来越多的设计师开始关注传统几何造型艺术在服装设计中的应用价值。如何将传统的造型艺术与现代时尚设计相结合,并创造出新的表现方式,成为研究的关键。在对几何造型的历史渊源及其相关的形式特点进行分析的基础上,对服装廓形、肌理图案、面料中的几何元素在现代服装设计中的立体表现进行分析研究,有利于探索其完美结合后的艺术和商业价值。     

An Analysis of Foreign Language Learning Styles from the Cognitive Perspective

From the 1970s,learning styles began to enter the domain of foreign language learning researches.Foreign language learning style is often regarded as a significant factor attributing to individual differences among language learners.Nowadays,many researchers begin studying individual learners’characteristics and exploring how different learners interact with external factors from cognitive perspective.The field-independence/dependence construct became a focus.Based on previous studies,the paper is committed to analyzing the nature of FID learners.It is expected that this research can establish a well-grounded basis for following studies.

维生素C和免疫多糖对中华倒刺鲃非特异性免疫功能的影响

在中华倒刺鲃每千克基础饲料中分别添加免疫多糖2g、免疫多糖4g、维生素C（VC）700mg、VC1400nag、VC700mg＋免疫多糖2g、VC700mg＋免疫多糖4g、VC1400mg＋免疫多糖2g、VC1400mg＋免疫多糖4g,以基础饲料为对照组,连续投喂2周后,通过测定血液白细胞的数量,白细胞吞噬能力,血清、头肾和脾脏的溶菌酶活力,探讨不同浓度的免疫多糖和VC对中华倒刺鲃非特异性免疫功能的影响．结果表明：VC和免疫多糖都能提高中华倒刺鲃免疫机能,且免疫多糖和VC二者间在较低浓度组合时有协同作用,高浓度组合时反而产生拮抗作用．免疫多糖和VC的最适宜组合浓度为（VC700mg＋免疫多糖2g）／kg基础饲料．     

3DV quality model based depth maps for view synthesis in FTV system

Depth maps are used for synthesis virtual view in free-viewpoint television (FTV) systems.When depth maps are derived using existing depth estimation methods,the depth distortions will cause undesirable artifacts in the synthesized views.To solve this problem,a 3D video quality model base depth maps (D-3DV) for virtual view synthesis and depth map coding in the FTV applications is proposed.First,the relationships between distortions in coded depth map and rendered view are derived.Then,a precisely 3DV quali...     

在《C程序设计》教学中引入ACM/ICPC的学习模式

《C程序设计》已经成为很多高等院校中计算机专业的一门必修课程,它将成为学生走上工作岗位后一种非常有用的工具,也会成为学生学习其它计算机语言的基础。本文通过引入ACM/ICPC的竞赛方式,培养学生的主动式学习、竞争式学习和协作式学习模式,同时培养学生的创造性思维模式。     

中美数学思维观的比较研究

中美两国数学教育界对学生数学思维的发展都非常重视。我国学者从形象思维、抽象思维、直觉思维等角度对之进行研究和探索;美国学者从儿童生活实际出发,认为学生数学思维包括：匹配与区分、分类、排序、顺序、建模。在论述思维发展时,都结合学生的实际,以案例的方式进行描述。两国在研究的逻辑方法上存在显著差异。我国研究体现出从一般到特殊的特点,而美国的研究则体现出从特殊到一般的特点。比较两国的研究,吸取各自所长,有利于促进我国基础教育数学课程改革的健康发展。
