新闻大学 2007年第4期 23-34,89页

作者：赵建国复旦大学新闻学院上海200433

1910年,中国报界在南京组织了近代第一个全国性的报界团体——中国报界俱进会,这个以国人自办报馆为主体的同业组织,致力于民族报业的发展,显示出报界群体扩张实力、发挥社会功能的意愿。它的成立大会、北京会议、上海特别大会所通过的... 详细信息

1910年,中国报界在南京组织了近代第一个全国性的报界团体——中国报界俱进会,这个以国人自办报馆为主体的同业组织,致力于民族报业的发展,显示出报界群体扩张实力、发挥社会功能的意愿。它的成立大会、北京会议、上海特别大会所通过的系列议案,不仅表明报界的联合范围日渐扩张,且体现了其间报界结社的发展趋向和特征,象征着清末民初报界群体意识的日益自觉。在其存在的三年多时间内,中国报界俱进会从联络同仁,维护报界公益,到督促报界进步,守望时政环境,在近代新闻事业史上留下光辉的一页,并展示了近代中国新兴群体的社会生长历程,为探求社会转型时期新兴职业社团与国家政权的互动提供了具体的例证。

民国时期,纪念"九一"记者节是中共报刊的重要议题之一,相关报道与评论形成比较典型的媒介记忆实践,其内涵集中在重构记者形象,检阅新闻队伍,在一般意义上折射民国新闻界的历史意识和集体记忆。不过,以《新华日报》为代表的中共报刊,主张以马列主义引导新闻从业人员,再造职业传统,并争取言论自由,实现民主进步,政治色彩相当明显。这些极具舆论导向性的纪念文章,基本反映中共对时局的研判,突破职业界限,凸显媒介记忆的政治特性。

1 IntroductionIn conditions of circulatory shock, systemic inflammatory response (SIRS) plays a funda mental pathogenetic role, with activation of transcription nuclear factors(mainly NF- kB) and markedly increased production of cytokines (mainly TNF-a), which trigger the inflammatory cascade active ation. Recent research have identified a basic neural pathway that reflexively monitors and adjusts such response. It is through the rapid activation (in 'real-time') of efferent vagus nerve fibres(the recentlyrecognized 'brain cholinergic antiinflammatory pathway' ) [1].There are show that the rapid activation cholinergic antiinflammatory pathway can protect against the hemorrhagic shock[2,3].
