创造国际直接投资新环境开拓中俄经贸合作新局面

中俄两国经贸关系走上了正常发展的轨道,相互投资成为深化两国经济关系的重要内容。国际直接投资是突破贸易壁垒、进入一国市场的重要手段,也是稳定中俄经济关系的根本基础。中俄相互投资存在经济转轨尚未完全实现、法律法规不健全、缺乏有效的筹资渠道、沟通渠道不畅等制度性和基础性障碍。为促进中俄两国相互投资健康、快速发展,应在签定双边投资协定、建立中俄商业协会、开辟投资融资途径、相互建立工业园区以及举办投资洽谈会等方面构建相互投资的宏观环境。     

过敏性休克死亡机体内白三烯变化的研究

本研究采用反相洗脱高效液相色谱(HPLC)法检测青霉素和血清过敏休克致死机体中自三烯(Leukotrienes,LTs)。(1)过敏休克前血中未检出LTs的任一组分,休克死亡后检出LTB_4和LTD_4。青霉素过敏血中LTB_4含量是10.10±4.76(ng/ml),LTD_4是26.75±6.55(ng/ml),未检出LTC_4和LTF_4。(2)正常动物肺,脾和肾中均未检出LTs。过敏休克的肺,脾和肾中不仅检出LTB_4和LTD_4,而且在不同脏器中呈规律分布。青霉素过敏肺中LTs_4是23.75±3.80(ng/g),LTD4是58.58±11.39(ng/g))未检出LTC_4和LTE_4。脾中仅有LTB_424.36±3.62(ng/g)。肾中仅有LTD_12.17±2.55(ng/g)。(3)过敏休克致死机体置室温6或12h,或置冰箱48h再测LTs,未见明显变化。(4)青霉素和血清诱发的过敏休克中,LTs的增加和分布是一致的。本研究提示:LTs含量和分布的变化是过敏性休克所共有,可为过敏性休克急死的法医学死因检定提供有价值的证据。     

金黄色葡萄球菌黏附素FnBPB-ClFA共表达质粒的构建与原核表达

采用PCR方法对编码金黄色葡萄球菌纤黏蛋白B的D区和纤黏蛋白原凝集素A的A区基因片段进行了特异性扩增,并通过重叠延伸PCR扩增了FnBPB-ClFA串联基因,构建了克隆质粒pMD19-FnB-PB-ClFA。将该基因片段定向插入到原核表达载体pET-32a(+)中,构建了表达质粒pET-FnBPB-ClFA,并将其转入宿主菌BL21(DE3)。SDS-PAGE分析表明,在1mmol/L IPTG诱导下,在51ku处出现了与目的蛋白一致的外源蛋白带。Western-blot分析表明,所表达的蛋白与目的蛋白一致。上述结果表明,该融合基因在原核细胞中成功表达。     

检测青霉素过敏性休克机体血中IgE类抗体

采用酶联免疫吸附试验(ELISA)法,检测青霉素过敏性休克豚鼠体内的IgE类抗体。结果显示:休克组血清中总IgE的量明显高于对照组(P<0.01)。用青霉噻唑蛋白(Penicilloylated Protein)作包被抗原,检测特异性IgE,以阴性参考血清的平均光密度加3个标准差作为阳性判断标准,发现过敏性休克动物血清中特异性IgE均呈阳性反应。本研究还发现:休克组动物在休克前、后特异性IgE间的差异具有高度显著性(P<0.01),虽然休克后特异性IgE略下降,但仍明显高于阳性标准。本研究认为:IgE量的变化与发生过敏性休克的关系应是:体内IgE升高并不必然导致过敏性休克,但过敏性休克的发生甚至导致死亡,应是IgE,特别是特异性IgE出现和升高的结果。     

Trade Measures and Climate Compliance: Institutional Interplay Between WTO and the Marrakesh Accords

This article examines the potential of trade measures to induce more climate-friendly policies, focusing on the relationship between global trade rules and the Kyoto climate regime. At the core of this interplay is the normative consistency of trade-related rules in the two regimes and any hierarchical relationship between them. The stronger clout of the WTO and its compulsory dispute settlement system suggest that issues involving competing claims would be referred to WTO bodies. Such bodies have so far been restrictive regarding the exceptions in WTO agreements to the general ban on embargoes and discrimination. The normative compatibility of the two regimes will also depend on their participatory interplay, specifically how they differentiate groups of actors as to rights and obligations. Non-members of WTO receive the least protection, and their vulnerability to climate-related trade measures is largely determined by their interdependence with states that consider employment of such measures. Among WTO members, the findings of a dispute settlement body would presumably differ depending on the status of the target under the Kyoto Protocol. A non-complier with Kyoto commitments would be more shielded than a non-party, because by joining the Kyoto regime a non-complier has exposed itself to regime-internal and less trade intrusive measures that should be exhausted first. A third dimension of interplay is linkage, or efforts to influence the regime interplay. To date there has only been moderate cross-agency coordination, but considerable attention is paid within each regime, including in the Millennium Round of trade negotiations, to the desirability of avoiding conflict between them.     

Data Protection: An Opening Door?

Swedish public law has incorporated a general rule of public access to documents, and to information in the wider sense, since the Freedom of the Press Act of 1766. On the Community level, the relationship between Regulation (EC) 45/2001 on data protection and Regulation (EC) 1049/2001 on public access to documents exemplifies the tension between the public's interest in scrutinising the administration carried on in its name, and the integrity of the individual. However, a similar tension exists between Sweden's Personal Data Act of 1998, implementing Directive 95/46, and the Freedom of the Press Act. A misuse model of data protection law, by seeking to concentrate on serious rather than technical infringements of privacy, might serve to ease the tension.
