共词分析及网络分析法探测乳腺癌转移相关基因

目的:探测乳腺癌转移相关的基因,为乳腺癌转移的早期诊断和个性治疗提供参考。方法:检索Pub Med数据库获取文献,利用Meta Map进行概念匹配,下载匹配结果,并导入到数据分析软件,得到乳腺癌转移相关基因和基因-基因矩阵;使用Ucinet6建立乳腺癌转移相关基因的相互作用网络,分析网络的相关指标。结果:tp53、thra、erbb2、esr1、cdh1、egfr、nr4a1、cd69等是乳腺癌转移核心基因。结论:基于共词分析法能获得乳腺癌转移相关基因,但cd69对于乳腺癌转移的具体过程尚不明确,需要进一步验证。

Analyses on Research Status of CSR in the World

Based on the web of Science database, such as the countries, research institutes, core authors, key journals and the distribution of research fields, the number of corporate social responsibility（CSR）, articles published during 20 years （1994 to 2013 ） in the world were analyzed by bibliometric method. The total of 1,544 articles and their top 20 countries, research institutes, core authors, key journals and research fields for the literature types, the number of annual articles was retrieved globally. Analyses of status and trends of CSR researches in the world based on bibliometrics were performed for providing information to CSR researchers and decision makers.

仙道之象:道教对唐千秋镜的影响

千秋镜是唐玄宗为庆祝自己的生日,于自己的诞节——千秋节那天颁赐群臣的铜镜。另外,群臣为贺寿也铸造千秋镜作为礼品奉献给玄宗。虽然传世及考古发现的千秋镜很难明确地断定是皇帝赏赐还是群臣所献[1],但这类铜镜的特征却是十分鲜明的。根据《全唐诗》中千秋节诗作、千秋镜著录和以往学者的研究,大体可将千秋镜分为二类,第一类。
