20世纪五六十年代中国宪法运行制约机制与“文革”的爆发

“文革”的发动与当时中国的宪法运行机制存在着密切的联系。“法外制度”与“法内制度”的相悖,消解了阻止“文革”发动的外部屏障。可见宪法功能的弱化失去了阻止“文革”爆发的最后屏障。     

HIV感染者与体育运动

目的:探讨体育运动对艾滋病毒感染者免疫功能的影响,以及艾滋病毒感染者运动比赛时的传染性和预防措施.结果:适度的体育运动可以提高艾滋病毒感染者的免疫功能,并作为辅助治疗手段在艾滋病毒感染者的综合治疗中起着重要作用.至今还未发现因从事体育运动及比赛而感染艾滋病的病例,但在运动中当血液明显暴露在开放性创口时,艾滋病毒的传播是可能的.预防的措施应注重对出血的及时发现和处理,并加强对运动员的教育和特殊管理.

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。

论古代文学研究的"当下关怀"

呼吁古代文学研究的“当下关怀”,并提出一些思考和建议。古代文学研究应在坚守审美本位、纯文学本位、纯学术本位的前提下,尽可能地关注现实,关注国计民生、世道人心,主动介入、积极参与政治文明建设、道德建设和社会文化建设,对当下流行的文学思潮、文化思潮做出“回应”,发出自己的声音。古代文学研究只有走出象牙塔,贴近现实生活,贴近公众,才更有活力。古代文学只有走进当下,才会“复活”起来,才更有价值。古代文学研究者应“定位”为人文知识分子,以学术研究为高尚事业,代表社会良心和公论,将自己的思想识见贡献给时代,实现人生理想。
