涅槃式的文化建构——《故事新编》浅探

在《故事新编》中,鲁迅以现代的文学视角,力图消解传统文化中的“光晕”,发掘民族精神文化的内涵,以此来重新塑造新的英雄、斗士形象,期望以此在文化批判中,改变旧的文化表现形式,改变旧中国国民的个性。     

中西医结合治疗粘连性肠梗阻临床观察

观察中西医结合治疗粘连性肠梗阻的临床疗效。将127例粘连性肠梗阻病人随机分成二组:对照组采用单纯西医治疗;治疗组在西医治疗的基础上加用加味承气汤胃管注入及保留灌肠,同时配合针灸治疗。结果,治疗组治愈率明显优于对照组,两组比较有显著性差异(P<0.05)。结果表明,中西医结合治疗粘连性肠梗阻可显著提高疗效,值得推广。     

传统危机意识的现代价值及其反思

中国传统文化蕴涵着较为丰富的关于危机的思想理念,主要表现为两个特点:一是自然危机意识与社会危机意识兼具;二是危机的处理和防范注重德性.中国传统危机意识并未在社会发展进程中占主导地位,从思想根源上看乃是"天人合一"的理念所致;从社会根源上看乃是封建专制的弊端所致.当今,在和谐社会构建中,传统危机意识可在以下方面彰显其现代价值:一是善于正视矛盾,居安思危;二是善于处理矛盾,临危不乱;三是善于化解矛盾,以和为贵.     

将民族传统文化融入思想政治理论课的途径

思想政治理论课传授民族传统文化要坚持辩明“精华”与“糟粕”的基本原则;坚持传统文化为思想政治教育服务的方向;坚持中华传统文化“多元一体”的内容;坚持科学评析“文化复古”的立场。在教学中,要从教材体系、课堂教学和实践教学上探索民族传统文化融入思想政治理论课的“三进”问题。     

The information seeking behaviour of the users of digital scholarly journals

The article employs deep log analysis (DLA) techniques, a more sophisticated form of transaction log analysis, to demonstrate what usage data can disclose about information seeking behaviour of virtual scholars – academics, and researchers. DLA works with the raw server log data, not the processed, pre-defined and selective data provided by journal publishers. It can generate types of analysis that are not generally available via proprietary web logging software because the software filters out relevant data and makes unhelpful assumptions about the meaning of the data. DLA also enables usage data to be associated with search/navigational and/or user demographic data, hence the name ‘deep’. In this connection the usage of two digital journal libraries, those of EmeraldInsight, and Blackwell Synergy are investigated. The information seeking behaviour of nearly three million users is analyzed in respect to the extent to which they penetrate the site, the number of visits made, as well as the type of items and content they view. The users are broken down by occupation, place of work, type of subscriber (“Big Deal”, non-subscriber, etc.), geographical location, type of university (old and new), referrer link used, and number of items viewed in a session.     

基于引文与载文指标的中国科普领域核心期刊分析

【目的】探索中国科普领域核心期刊,帮助了解科普事业发展的理论支撑和科普文章发表的主要阵地,进而有针对性地采取措施,推动中国科普期刊的建设和发展。【方法】 主要采用引文分析方法和载文统计方法。基于引文分析的科普主题文献来源于CSSCI数据库;基于载文统计的科普主题文献来源于CNKI数据库。【结果】 基于CSSCI引文分析的科普主题文献被引频次最高的10本中文期刊,将其称为中国科普领域高被引核心期刊;基于CNKI数据的科普主题文献载文量最高的10本中文期刊,除了已经进入中国科普领域高被引核心期刊阵营的两本之外,将其余8本期刊称为中国科普领域高载文核心期刊。【结论】 中国科普领域高被引核心期刊,为中国科普事业的发展发挥着提供理论支撑的作用,应更多地吸收全球科普发展的理论和实践经验;中国科普领域高载文核心期刊,是中国科普文章发表的主要阵地,今后应该更加注重提高科普文章的质量。     

Inhibition of preadipocyte differentiation by Lycium barbarum polysaccharide treatment in 3T3-L1 cultures

BackgroundLycium barbarum (also called wolfberry), a famous Chinese traditional medicine and food ingredient, is well recognized for its significant role in preventing obesity; however, the molecular mechanisms underlying its preventive effects on fat accumulation are not well understood yet. The aim of this study was to determine the effects and mechanism of Lycium barbarum polysaccharides (LBP) on the proliferation and differentiation of 3T3-L1 preadipocytes. MTT was used to detect the proliferation of 3T3-Ll preadipocytes. Oil red O staining and colorimetric analysis were used to detect cytosolic lipid accumulation during 3T3-L1 preadipocyte differentiation. Real-time fluorescent quantitative PCR (qPCR) technology was used to detect peroxisome proliferator-activated receptor γ (PPARγ), CCAAT/enhancer-binding protein α (C/EBPα), adipocyte fatty-acid-binding protein (aP2), fatty acid synthase (FAS), and lipoprotein lipase (LPL) expression.ResultsThe concentration of LBP from 25 to 200 μg/mL showed a tendency to inhibit the growth of preadipocytes at 24 h, and it inhibited the differentiation of 3T3-L1 preadipocytes in a dose-dependent manner. In the preadipocytes treated with 200 μg/mL LBP, there were reduced lipid droplets in the cytoplasm, and its effect was opposite to that of rosiglitazone (ROS), which significantly reduced the PPARγ, C/EBPα, aP2, FAS, and LPL mRNA expression of adipocytes.ConclusionsLBP exerts inhibitive effects on the proliferation and differentiation of 3T3-L1 preadipocytes and decreases the cytoplasm accumulation of lipid droplets during induced differentiation of preadipocytes toward mature cells. Above phenomenon might link to lowered expression of PPARγ, C/EBPα, aP2, FAS, and LPL after LBP treatment. Thus, LBP could serve as a potential plant extract to treat human obesity or improve farm animal carcass quality via adjusting lipid metabolism.How to cite: Xu X, Chen W, Yu S, et al.

以功效为切入点开展中药学教学的体会

中药学知识零碎、涉及面广、不易学习和掌握。而中药功效在中药理论中居于关键地位,它是联系药性与主治的桥梁与纽带。很多中药的四气五味、升降浮沉、临床应用等,几乎都可以从功效中体现出来。因此,教师可以通过重点分析和教授中药功效,并以此作为切入点,进行中药学学科的教学,以达到更快速、系统、牢固的学习记忆。
