从金融地理学的角度出发,运用演化博弈模型分析得出,金融集聚有利于区域内知识溢出效应的发挥,通过集聚网络知识的系统效应、创新效应、技术进步效应和信息升级效应,提升中心区域内的经济发展水平。此外,如果区域间知识水平差距过大,会形成知识锁定的局面,造成区域间知识溢出阻塞效应,拉大区域间主体知识水平差距,从而加剧区域间经济发展的不均衡。因此,营造区域间良好的金融生态环境,对落后区域的企业给予更多的金融支持,拓宽中小和新兴企业的融资渠道,引导性地使金融集聚发挥辐射作用,能够使金融的正向集聚效应提升经济发展水平。

2004年作者提出"生态长江口"概念之后,并没有对其进行过严格的定义。生态长江口是一个符合国家相继提出的"实施海洋开发"、"发展海洋产业"和建设"生态文明"战略的新概念,具有强大的生命力。本文对"生态长江口"概念进行了定义,并从非原生态型、生态建设型、海洋安全型、生态经济型、生态管理型和生态城市型等6个方面对其内涵进行了诠释,提出了生态长江口的建设目标、指导原则与实施战略构想,探讨了包括建设长江口保护区体系、构建生态长江口安全保障体系和打造生态长江口海岸带经济特区的基本构架。

冠礼是传统社会男子成年的标志,古代礼仪系统的起点。冠礼源出远古部族时代成人礼,是古初成人礼经过自觉仪式改造和精神提升的全新生活仪轨和文化形式。《礼记·冠义》作为儒家礼仪释义文献的代表作,对冠礼所象征的"成人之道"进行了系统解说。古人所谓成人,是社会—伦理价值意义上的,亦是性体论意义上的,人之异于禽兽的礼义本质在其生命中的实现与彰显。成人更意谓成德之人,即礼义在人生命中的充分实现。儒家冠礼释义围绕伦理—政治维度、德性—修养论维度和形而上—性体论维度三个方向展开。通过冠礼释义,使其义理信念落实于社会礼仪活动,同时通过对其内涵的揭示和解释,使礼俗获得点化和提升,从而实现了生活哲学化与哲学生活化的双向互动。

AIM: To select characteristic endogenous metabolites in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) patients and to identify their molecular mechanism and potential clinical value. METHODS: An ultra performance liquid chromatography and linear trap quadrupole-Orbitrap XL-mass spectrometry platform was used to analyze endogenous metabolites in the homogenate of central tumor tissue, adjacent tissue and distant tissue obtained from 10 HBV-related HCC patients. After pretreatment with Mzmine software, including peak detection, alignment and normalization, the acquired data were treated with Simca-P+software to establish multivariate statistical analysis based on a pattern recognition technique and characteristic metabolites highly correlated with changing trends in metabolic profiling were selected and further identified. RESULTS: Based on data acquired using Mzmine software, a principal component analysis model (R2X = 66.9%, Q2 = 21.7%) with 6 principal components and an orthogonal partial least squares discriminant analy-sis model (R2X = 76.5%, R2Y = 93.7%, Q2 = 68.7%) with 2 predicted principal components and 5 orthogonal principal components were established in the three tissue groups. Forty-nine ions were selected, 33 ions passed the 2 related samples nonparametric test (P < 0.05) and 14 of these were further identified as characteristic metabolites that showed significant differences in levels between the central tumor tissue group and distant tumor tissue group, including 9 metabolites (L -phenylalanine, glycerophosphocholine, lysophosphatidylcholines, lysophosphatidylethanolamines and chenodeoxycholic acid glycine conjugate) which had been reported as serum metabolite biomarkers for HCC diagnosis in previous research, and 5 metabolites (betasitosterol, quinaldic acid, arachidyl carnitine, tetradecanal, and oleamide) which had not been reported before. CONCLUSION: Characteristic metabolites and metabolic pathways highly related to HCC pathogen

"信"是儒家伦常价值系统的核心结构要素,其本义为人之内在生命情志通过"言"而由内向外的真实开启。对儒家而言,"信"是人之生存本质的内在要求,是奠定诚信价值之生存论根基的"性之德"。儒家以"信"为朋友之伦的主德,意在以忠信为本,建立己与人之间的相互接纳、相互尊重和相互信任,以此构成社会公共生活与人际交往的基础。信在五常序列中的位置足以彰显其重要意义。儒家主张以"义"引导和规范"信",并非对"信"之贬低,而是为了从根本上成就信德。现代诚信伦理纯然是外在于人之情性的契约式工商伦理形式。儒家信德不可盲目追求"现代转化"而丧失自身价值追求和精神品位,而应持守自身,保证教养生活不致失坠。
