    目的:采用高脂高能量饮食诱导大鼠制备非酒精性脂肪性肝病(NAFLD)模型,给予饮食干预治疗,观察大鼠血清生化指标及肝脏组织病理病变,初步探讨胰岛素及其相关信号通路因子胰岛素受体(INSR)、胰岛素受体底物l(IRS-l)在NAFLD发病机制中的作用和饮食干预的影响。 方法:将40只雄性Sprague-Dawley大鼠随机分为5组,分别为8周正常饮食组(NC1组),8周高脂饮食组(HFD1组),16周正常饮食组(NC2组),16周高脂饮食组(HFD2组)和饮食干预组(DIET组)。检测大鼠空腹胰岛素水平及相关生化指标,观察肝脏组织病理改变,通过免疫组化、蛋白质印迹分析(Western-blot...Objective: The nonalcoholic fatty liver disease (NAFLD) rat model was established by high-fat diet. The aim of the study was to investigate the therapeutic role of dietary intervention and the expressions of insulin receptor (INSR) and insulin receptor substrate 1 (IRS-l) in the progression of NAFLD. Methods: Forty Sprague-Dawley (SD) rats were randomly divided into five groups: two normal cont...学位:医学硕士院系专业:医学院_内科学学号:2452012115313

    随着经济全球化的不断推进,国际资本市场逐渐呈现一体化趋势。作为反映国民经济的“晴雨表”和资本市场的重要组成部分,各国股票市场间存在怎样的关系呢?股市间的相依性结构对投资者合理制定投资组合策略以及监管当局有效防范国内外股市风险,维护市场稳定,推进股市健康发展具有重要的启示意义。中国已经成为全球第二大经济体,大陆股票市场也在近十年迅速发展。研究中国大陆股票市场与世界股票市场间的相依性结构具有重要的现实意义。 股市间的相依性历来是人们关心的重点,学者们对其进行了大量的研究。阅读已有相关文献,发现学者们常用的研究方法有Pearson相关系数法、Kendall相关系数法、Spearman相关系数法、多...With the promoting of economic globalization, the international capital markets gradually show an integration trend. As a barometer which reflects national economy and an important part of the capital market, what is the relationship between international stock markets? Dependence structure between international stock markets has important implications for investors to make rational diversificatio...学位:经济学硕士院系专业:经济学院_数量经济学学号:1542013115203

    二胡作为中国传统民族乐器,有着悠长的历史。在音乐文化的不断发展下,其演奏风格特点与伴奏形式也在不断发生变革。现如今与钢琴的配合越来越频繁,深受观众喜爱。近年来,二胡等中国传统乐器也开始走出国门,走向世界。 钢琴伴奏是一门融入了和声、复调、配器、曲式分析等西方作曲技巧于一体的学科。同时,钢琴是欧洲音乐艺术与科技文化发展了几百年的产物,作为二胡演奏整体的一部分,它与中国传统器乐之间的配合,是很有挑战的。两者合作一般会涉及到诸如,二胡与钢琴的音响效果融合、律制不同等等方面的问题,种种这些都需要我们去研究探索。Erhu, as one of traditional Chinese national musical instruments, has a long history. With the continuous development of musical culture, its playing style characteristics and accompaniment forms are also constantly changing. Nowadays, it cooperates with piano more and more frequently, which is deeply loved by the audience. In recent years, Erhu and other traditional Chinese instruments also go ab...学位:艺术学硕士院系专业:艺术学院_音乐与舞蹈学学号:1872013115359

    在环境监测,食品安全,化学、医药产业和日常生活中,如何便捷地检测出目标物的化学成分成为了一个迫切的需求。传统的化学检测方法往往需要专业的检测人员在实验室进行,并且一种化学分子对应一种专门的检测方法,同时对多种混合物质鉴别的方法并不多见。拉曼光谱是一种指纹式的鉴别方法,一种特定的分子往往具有数个拉曼特征峰,这些特征峰的拉曼偏移是固定的。因此拉曼光谱可以通过特征峰同时鉴别出多种化学分子,检测时间仅需要几秒钟,而且操作简单,只需要将探头对准被测物即可,这为化学检测走出实验室提供了极大的便利。 拉曼光谱仪推广应用的瓶颈之一在于仪器比较昂贵,即使是便携式拉曼光谱仪的价格也比一辆家用轿车高。其原因是光学...An easy and fast identification technology for chemical molecules is in huge demand in environment monitoring, food safe, chemical and medicine industry and even in daily life. In traditional approaches, professionals are normally employed to make the identification in a laboratory, and each chemical is generally determined only by a specific recipe. A method is still in lack for detecting multipl...学位:工学硕士院系专业:物理与机电工程学院_机械制造及其自动化学号:1992012115272

    在西方发达国家,商业信用作为一种重要的融资方式,被称作与证券直接融资、银行间接融资并列的“第三条融资渠道”。在我国,由于经济体系的不完善,市场中信息的不对称,融资配给现象较为严重。通过商业信用的使用可以解决企业融资困难的问题,如何提高企业对商业信用的使用,企业商业信用的使用受到哪些因素的影响等问题值得我们研究。以往学者往往从组织层面研究企业规模,银行信用等对商业信用的影响,而忽略了企业内部管理人员的作用。1984年Hambrick&Mason提出的“高层梯队理论”认为管理者的特质影响着他们的战略选择,从而影响企业的行为,当然也影响着企业对商业信用使用的选择;另一方面,高管的个人特征向外界传达的...In western developed countries,trade credit,as a kind of important financial mode,is called "the third finacial channel",which is in range with securities direct financing and bank indirect financing.While in China,unperfect economic system and information asymmetry in the market make it severe for financing ration.We can handle the problem of enterprises' financial difficulties through the use of...学位:会计硕士院系专业:管理学院_会计硕士学号:1752013115118
