李白《丁都护歌》"石芒砀"解

在中国的古代文学作品中,往往会运用多种社科专业词语进行文学写作.如果仅从文学角度对这些词语进行考证,只会让人迷惑不解.文章采用训诂学的方式,考证古人文学作品中的注解,依此来探索运用多种社科知识考证古代文学作品的途径.

在"快乐足球"教学中培养高职学生的职业素质

学生对体育运动有无兴趣,直接影响他们进行体育锻炼的自觉性和极积性,也决定着体育知识的掌握和技能的形成。“快乐足球”教学能促进学生把学习与足球有关的知识视为自身的需要,积极开展足球活动,刻苦进行锻炼,从而提高各类专业人才的基本素质。

CIDE gene expression in adipose tissue,liver, and skeletal muscle from obese and lean pigs

The expression of the cell death-inducing DNA fragmentation factor α-like effector (CIDE) family including Cidea, Cideb, and Cidec was significantly increased in mouse and human models of obesity. However, there was less information on these genes’ expression in pigs. Here, we hypothesized that different fat accumulation between lean (Duroc×Landrace×Yorkshire gilts, DLY) and obese (Lantang) pigs was attributed to porcine CIDE-modulating lipid metabolism. Our data showed that Cidea and Cidec were expressed at a high level in adipose tissue, and at a relatively high level in skeletal muscle, whereas Cideb was mainly expressed in the liver in both breeds of pig. Lantang pigs had higher white adipose and skeletal muscle Cidea and Cidec mRNA abundance, and hepatic and muscle Cideb mRNA than DLY pigs. Lipid metabolism-related genes including sterol regulatory element binding protein 1c (SREBP-1c), hepatocyte nuclear factor-4α (HNF-4α), peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α), fatty acid synthase (FASN), diacylglycerol O-acyltransferase 1 (DGAT1), and DGAT2 showed a higher expression level in adipose tissue from obese pigs than in that from lean pigs. Lantang pigs exhibited higher mRNA abundance for liver SREBP-1c, HNF-4α, and PGC-1α, and higher skeletal muscle SREBP-1c, HNF-4α, PGC-1α, and DGAT2 expression, as compared with DLY pigs. However, the perlipin2 mRNA levels in adipose tissues, liver, and skeletal muscle were significantly lower in obese pigs than in their lean counterparts. Furthermore, plasma non-esterified fatty acid (NEFA), glucose, and triacylglycerol (TAG) levels were greater in obese pigs than in lean pigs. Finally, data from correlation analysis further found that CIDE mRNA expression was positively correlated with back fat thickness (BFT), abdominal fat mass (AFM), and the levels of NEFA, TAG, and glucose in the two breeds. Collectively, these data revealed that the porcine CIDEs possibly modulated lipid metabolism and contributed to the development of fat deposition and obesity in Lantang pigs.

美感体验中的三维透视——论《二十四诗品》朦胧美

历年来关于《二十四诗品》的美学研究是层出不穷的,从架构美学到思想美学到生态美学到诗歌美学到理想美学等等,这种高度理论性的美学研究使得整部著作更加具有魅力性。但是这种提炼浓缩后的理论升华在无形中也附加上了论者们的美学理想,使得《二十四诗品》美学价值或多或少地存在着"膨胀"的现象。文章将从美感体验出发,旨在挖掘分析能被直接感知的朦胧美和美的朦胧负担,让《二十四诗品》的美变得更加有迹可循。     

教师口语规范化初探

“为人师表”的教师职业要求教师口语要力求规范化。国家规定普通话是法定的教学语言。原则上不允许用方言授课。教师口语的示范性决定了规范的教师口语有其重要意义，以及提出了与普通口语不同的要求。     

高等师范院校学生两项资助政策的研究

按国家有关政策的规定，师范生享受专业奖学金和免缴学杂费、住宅费的待遇。通过调查25个省、市、自治区的35所师范院校近几年执行上述两项资助政策的实际情况，提出改革现行资助政策的设想：收费政策与其他院校并轨；在学资助与职后资助并举，以职后资助为主。     

高师声乐教学中对不同作品风格的掌握与处理

高师声乐教学中，要学生掌握和处理好作品的风格、情感、特征；了解作品的体裁、时代背景、民族特色、语言等，都是十分重要的；对全面提高学生的音乐素养，提高声乐教学的整体水平，也是非常必要的。
