当今世界的竞争是综合国力的竞争,而文化软实力越来越成为综合国力的一部分,与经济、军事等硬实力相结合,成为推动当今社会发展的重要力量。我国也已把文化软实力建设的重大课题提了出来。我国要想在激烈的国际竞争中赢得主动、成为世界意义的大国,提高文化软实力,这是一门我们必须面对的必修课,我们别无选择。     

基于SVAR模型的货币政策对企业经营影响研究——以工业、房地产业、信息和计算机软件业为例

旨在建立一个运用多维度定量指标判断经理报酬激励强度的评价方法，有利于全面认识各上市公司经理报酬的激励程度。根据评价结果把经理报酬激励强度分为激励不足、适中、过度，并实证研究不同激励强度上市公司治理结构的特征，进而提出改进经理报酬激励公平和效率的有效手段，提高对不同类型企业高管薪酬管理的针对性。

富锗金针菇菌丝体多糖的分离纯化及对自由基的清除能力

以金针菇为研究材料，通过液体发酵技术获得富锗金针菇菌丝体，对富锗金针菇菌丝体多糖进行了分离和纯化，通过体外抗氧化试验测定了富锗金针菇多糖对自由基的清除能力。试验表明:富锗金针菇菌丝体经提取纯化后得到单一组分多糖，纯度为99.78%，不含蛋白质；富锗金针菇菌丝体锗含量为7.42 mgg，有机锗的转化率为6.25%；富锗金针菇多糖经纯化后抗氧化性显著增强，对氧自由基、羟自由基和DPPH自由基均具有较好的清除作用，与空白对照相比均具有显著差异，自由基清除率随富锗多糖的浓度增加而增强。在试验范围内当富锗多糖浓度为900 μgmL时，对氧自由基、羟自由基和DPPH自由基的清除率最高分别达68.16%、64.26%和64.3%。该富锗多糖具备开发为天然抗氧化剂、功能性食品或药品的潜力。

Molecular cloning and functional analysis of goose interferon gamma

The cDNA for goose interferon gamma (goIFN-gamma) was cloned from PHA-stimulated goose peripheral blood mononuclear cells (PBMCs) by RT-PCR. This cDNA encodes a 19-amino acid signal peptide and a 145-amino acid mature protein, which shares a high homology with duck IFN-gamma. Recombinant mature goose interferon gamma (rgoIFN-gamma) generated from both prokaryotic and eukaryotic expression systems effectively inhibited the replication of goose paramyxovirus and recombinant vesicular stomatitis virus in vitro. These antiviral activities were abrogated by rabbit anti-rgoIFN-gamma antibodies in vitro. Furthermore, rgoIFN-gamma stimulated goose peritoneal macrophages to produce nitric oxide (NO) in vitro, demonstrating its macrophage activating factor (MAF) activity. Therefore, the availability of bioactive rgoIFN-gamma and its specific antibodies provides valuable tools for studying T cell immunity in geese.

Effect of food reductones, 2,5-dimethyl-4-hydroxy-3(2H)-furanone (DMHF) and hydroxyhydroquinone (HHQ), on lipid peroxidation and type IV and I allergy responses of mouse

The effect of long-term supplementation of food reductones, 2,5-dimethyl-4-hydroxy-3(2H)-furanone (DMHF) (2%, w/w), detected in many foodstuffs including soy sauce, and hydroxyhydroquinone (1,2,4-benzenetriol) (HHQ) (1.2%, w/w), detected in coffee, on mouse lipid peroxidation and type IV and I allergy responses was investigated. The effect of supplementation of these reductones combined with NO(2) inhalation (5-6 ppm) was also investigated. Levels of thiobarbituric acid-reactive substances in lung were remarkably increased, and those in kidney and liver were slightly decreased by supplementation of DMHF or HHQ. The degree of 2,4-dinitrochlorobenzene (DNCB)-sensitized lymph node cell proliferation as assessed by lymph node assay was remarkably enhanced by supplementation of DMHF or HHQ. Both the DNCB-sensitized and the trimellitic anhydride-sensitized increases in IgE levels of mice were enhanced to greater extent by supplementation of DMHF or HHQ. In no cases were additive effects of NO(2) inhalation observable. Allergen-sensitized type IV and I allergy responses of mice may be enhanced by supplementation of food reductones, DMHF or HHQ.
