Surface plasmons(SPs) exhibit unique characteristics due to participation of the conduction electrons within the metal and have been widely used in nanophotonic and optoelectric devices. SPs are often categorized into two types: Localized surface plasmons(LSPs) confined to subwavelength metallic objects and surface plasmon polaritons(SPP) propagating along metal-dielectric interfaces.

南唐饮宴文化繁荣原因浅探

东南文化 2008年第5期 38-42页

作者：傅玉兰南京师范大学文学院江苏南京210097

本文认为,南唐繁荣的饮宴文化是南唐词兴盛之沃土。而南唐饮宴文化之所以繁荣,原因之一是对前朝大唐文化的沿袭,其二是偏安暂定的小国环境中士人及时行乐的人生态度的影响。

Objective: This study aims to examine the causal relationship between inflammatory factors and the probability of developing vascular dementia (VD) using Mendelian Randomization (MR) and Chinese herbal medicine prediction method, and to screen potential Chinese herbal medicines for the prevention and treatment of VD. Methods: Single nucleotide polymorphisms (SNPs) that exhibit a strong association with vascular dementia (VD) were identified as instrumental variables from the summary statistics of genome-wide association studies (GWAS). The primary analytical method employed was inverse variance weighting (IVW), while auxiliary analyses included the MR-Egger method, weighted median method, simple model, and weighted model. A two-way Mendelian randomization analysis was conducted to assess the causal relationship between inflammatory factors and the risk of VD, thereby identifying the key inflammatory factors involved. The MR-Egger intercept test and Cochran’s Q test were employed to assess the horizontal polymorphism and heterogeneity of instrumental variables. A sensitivity analysis was conducted by excluding one method at a time. Ultimately, based on key inflammatory factors, predictions for the prevention and treatment using traditional Chinese medicine were made, along with the screening of homologous herbal remedies. Results: Based on the results of the forward MR, the probability of developing VD was elevated when the inflammatory factors CXCL10 and CXCL5 were expressed at higher levels, whereas the probability of developing VD decreased as the expression levels of IL-13 and IL-20RA increased. These findings were supported by the assessment of pleiotropy, heterogeneity, and sensitivity. The results of the reverse MR analysis showed that there was no causal relationship between VD, as an exposure dataset, and these four inflammatory factors. According to the key inflammatory factors, 37 Chinese herbal medicines such as Siraitia grosvenorii were selected. Their c

学术界对侯方域诗歌的研究主要集中在诗歌渊源、诗歌理论、诗歌创作等方面,表现为研究方法较为单一,研究不够深入,利用材料不够充分。今后的研究在文本细读的基础上应借鉴田野考察法、文化学、比较研究法等方法,借助文学理论进行系统性研究,挖掘包括墓志铭、书信、碑刻等更为广阔的研究资料。在诗名和文名、比较研究、整体研究、影响研究、艺术技巧、风格特色这几个方面,侯氏诗歌还有很大的研究空间。

以生存空间论为核心的地缘政治学过去主要用于考察国际关系与研究国家的对外战略，并因此曾一度成为西方大国对外扩张与侵略的理论依据而受到我们的长期否定。但客观地看该理论着眼于政治现象的空间分析．无疑可为我们描述和考察各类政治行为提供一种有借鉴价值的分析工具。毕竟人类的活动当然包括政治行为都必须依托并在一定程度上受制于特定的地理空间。基于此，本文尝试借用地缘政治学的相关概念，
