The cytosolic liver-specific growth factor-hepatic stimulator substance (HSS) has been shown to be able to amplify the rat hepatocyte proliferation responded to EGF. In order to get more insight into the mechanism, the regulatory effect of HSS on EGF-receptor(EGF-R) and the receptor phosphorylation at molecular level was studied. HSS partially purified from weanling rat liver was given to cultured hepatocytes and its influence on EGF-R specific binding and internalization as well as mRNA expression were investigated. The results showed that preincubation of hepatocytes with HSS could lead to an increase in [125I]-EGF binding to its receptors and inhibit EGFinduced receptor down-regulation. Furthermore, the overexpression of EGF-R mRNA stimulated by HSS was seen during 2-12 h after the incubation. Additionally, it was demonstrated with human hepatoma sMMC-7721 cells in Western blot that the EGF-R expression and the receptor autophosphorylation were increased with dose/timedependency after HSS treatment. These results strongly suggest that the mechanism of HSS action on hepatocyte growth might be related to its modulation on EGF-R and receptor-mediated signaling transduction.

我国刑法保护的生态法益是一种关系性、整全性的法益。在理解生态法益时,应当着眼于生态利益与生活利益的融合,个体权益与集体权益的重构,公民利益与国家利益的统合。在法益形态的认识上,重心不能全然放在个体利益抑或集体利益角度,而应该从个体利益与集体利益的互构,建立污染环境罪认定的多元入罪根据。污染环境犯罪的治理效果与国家发展战略优化、经济生产方式调整、社会生活方式转变等结构性因素转型紧密关联。在国家与社会的加速转型期,污染环境犯罪治理面临着诸多困境,需要在转型过程中持续传导新发展战略的价值理念,健全污染环境犯罪治理的法律规范及行政监管机制,提升社会公众参与污染环境犯罪治理程度,并调动充分的市场调节资源等实现多元治理。

以地缘性的嵌入与“脱嵌”理论为基础,基于上海市ZS街道生活体育社团的实地调研,探讨地缘生活体育对基层社会团结的重要功能,及以地缘生活体育为媒介的基层社会团结的建构路径。工业与信息社会的发展使社会成员日益脱嵌于“附近”的生活,在更广阔的现实世界或虚拟世界中建立社会关系,基层地缘空间出现空心化的形态,地缘共同体趋于解离。地缘生活体育是以基层地缘空间为依托的具有具身性与地方性、开放性与生活性的体育参与形式,地缘成员之间面对面的体育参与和互动能增进深度的社会交往。地缘生活体育蕴含着向生活世界的回归,在地缘交往空间内建构平等的沟通、信任和互惠的关系,培育地缘性的社会资本。发展地缘生活体育,有助于社会成员重新重视其“附近”的生活场域,产生共同体的意识和情感,建构地缘共同体以增进基层社会的公众参与及优化基层社会的有序治理。

污染环境犯罪是在经济与社会剧烈转型期呈现的复杂问题,犯罪治理需考虑经济、社会、生态环境法益的均衡。污染环境犯罪具有深刻的经济与社会根源,多样主体实施污染环境犯罪行为的动机与路径存在显著差异,犯罪治理不能是单一的线性模式。依据犯罪主体的犯罪行为类型及生成路径,需建构包括严格管控型治理、转型引导型治理与监督合规型治理在内的分层治理模式。该模式中涵括刑事立法、刑事司法、行政执法、刑事社会政策、刑事合规制度、企业合规体系、合规环境建设、转型政策支持、市场调节等多元机制。深入探索污染环境犯罪行为典型的生成路径,建构犯罪治理的多元分层治理模式,有助于生态环境犯罪的精准化治理,推动我国经济、社会、生态文明的整合发展。

人类社会经历了由传统农业社会向工业社会、信息社会发展的历史阶段,社会团结的实践场域、组织形式、资源基础等随之发生显著变迁。农业文明时期的社会生产与生活具有封闭性,信息获取与传播途径单一化,因而社会团结以同质化的刚性团结为主要特征。工业时代的社会生产与生活具有了流动性,信息与知识的形式趋于异质化,社会团结以各式各样的组织为载体,是建立在分工基础上的功能互赖。在信息社会中,信息技术为个体成员赋权与增能,使个体的主体意识与自主能力迅速增长,社会团结愈来愈建立在主体的选择意志与主观认同的基础上;社会团结的刚性、固定性、稳定性在持续减弱,而呈现出弹性、高自由度、弱联结性的团结形态。因而,需要高度关注社会团结发生的现实与互联网络并在的空间场域、社会成员自组织而形成的社会团结载体、公共意识与集体精神的培育等,促进社会整体团结水平与层次的提升,更好地推动国家与社会的可持续发展。
