Guanidine hydrochloride was chemically bonded to surface of modified silica by means of condensation with grafted amino groups. Ion-exchanging and complexing properties of the obtained adsorbent have been studied with respect to cations of Zn(II), Cu(II), Pb(II), Cd(II), Co(II) and metal-containing oxoanions of W(VI), Mo(VI), Cr(VI), V(V). Optimum conditions for quantitative extraction of the studied ions were determined. The structure and composition of Co(II) and Cu(II) complexes on the surface of the synthesized adsorbent have been investigated. The possibility of quantitative determination of cobalt(II) and copper(II) trace amounts after their preconcentration by the synthesized adsorbent was demonstrated.

本文证实了自金融危机爆发以来全球经常账户失衡程度的显著改善。具体来说,美国的经常账户赤字占GDP的比例从6%的高位下降了一半,到了3%;中国的经常账户盈余也有了显著下降。对上述两国失衡的降低,以及更具一般性的全球失衡程度的降低,我们接着考量了其仅仅是由于失衡被金融危机所打断而引起的暂时性偏移,还是长期性的调整。

Introduction. Pathological complete remission of liver metastases is a rare colon cancer treatment outcome with increased 5-year survival of 76%. Case report. Metastatic colorectal cancer patient with pathological complete remission of large hepatic metastasis after palliative chemotherapy in combination with bevacizumab is presented. Solitary liver metastasis measuring 8 cm was observed in computed tomography (CT) scan before combined treatment. The best radiological response during treatment with FOLFOX-4 and bevacizumab therapy was partial remission and patient underwent partial hepatectomy. Since the operation material was free of viable adenocarcinoma cells the effect of FOLFOX-4 in combination with bevacizumab treatment was interpreted as the pathological complete remission. Conclusion. Use of combination chemotherapy and targeted therapy with the aim to reduce initially unresectable liver metastasis is the best option to achieve complete pathological remission and significantly prolong survival.

在灾害面前,没有市是安全的。而当今的世界正迅速地城市化,在21世纪初期,世界人口的一半以上将居住在城市。城市化比例的提高,要求做出很大的努力来提供对城市人口最基本的服务。必须找到新的资源来提供足够安全的水、电、建筑材料和空间。对越来越少的土地和有限水资源的压力在不断增加,城市环境的恶化成了一个严重的问题。洪泛平原和易产生滑坡的山丘都被用来建房,而且常常不规范,质量低劣,这是因为在有工作机会附近的地区,没有价格合理的土地。第二届人类住区大会的最主要挑战,是确定人类居住可持续发展的策略和政策。需要注意的领域之一,是与城市化和环境恶化有关的灾害危险性的增加。

为探索农村社区产前保健项目对产妇的孕产期健康与保健相关知识、态度和行为的影响 ,采取整群随机抽样的方法确定要调查的村 ,入户问卷调查干预组 41 1名、对照组 442名产妇。结果表明 ,干预组产妇掌握母婴健康保健知识较好、正确或恰当态度率较高、正确行为率较高。但两组产妇对首次产前检查孕周的正确回答率均在 50 %以下 ,对孕期无异常也要定期产前检查的正确态度率不理想 (干预组 61 %、对照组 45% )。说明产前保健项目在一定程度上改善了产妇的知信行 ,但改善的力度还不够大。
