一报还一报——探究《远大前程》中的主题之一

<远大前程>作为狄更斯晚期著名的作品,围绕主人公匹普的发展历程进行描述,颂扬了狄更斯的人道主义精神,并揭示了其作为维多利亚时代的作家所固有的性道德、家庭道德等方面的理论.狄更斯强调扬善惩恶,不能容忍道德低劣者有幸福的结局,总是把好的命运赋予那些道德上的正面人物.

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。
