1为满足芬兰暴雨管控需要进行的缝隙透水路面水文模拟实验显示文摘芬兰开始对透水路面进行水文性能研究,是因为政府市政管理者对城市暴雨管理有一个分项计划——需要提出城市雨水的全新技术解决方案,故在2012~2014年度"全天候路面"研究项目中,对透水路面开展了专门的水文模拟试验研究。该项目由TEKES(针对技术和创新领域的芬兰国家投资机构)资助,具体合作承担该研究项目的 16家单位,含盖了市政管理者、建筑材料生产商、暴雨管控设计师、行业协会和芬兰国家技术研究中心(VTT)有限公司等,基本覆盖了与城市雨水管理相关的部门(和单位)。本研究项目还与瑞典由CBI(编辑注:应是瑞典水泥与混凝土研究院的瑞典文缩写)和24家合作伙伴承担的"绿色—灰色"研究项目(英文"Green-Grey",应是水泥混凝土生产二氧化碳减排技术方面的研究)进行了协作。气象报告显示,芬兰会遭受较大体量的降雨和较大强度的暴雨。人类社会正致力于拥有更好的环境保护和产生更少污染物的地表径流水,这两个问题都是开展本项目研究工作出发点。混凝土路面砖和路基材料层结合形成的透水路面(PBP),在芬兰还没有得到应用,是由于缺乏成熟的技术。本项目是在VTT实验室内进行雨水过滤仿真模拟(FS-装置)试验,对路面结构的各层材料进行单独或叠合组成层状系统,进行雨水过滤性能的评估,以模拟路面结构设计方案。实验室试验的优点是能够在保持所有其它参数不变的情况下,对各个关键因素的影响进行评价。通过本项目的研究,期望获得关于不同块型路面砖和路基结构的渗透性能的基础数据,例如一些典型变量(路面砖接缝和开孔面积的比例、填缝砂子的颗粒级配、粘结型复合材料接缝)的影响;还包含对地表雨水含堵塞物及后期清理程度的影响研究。另外,或在今后的项目中,这些基础数据可被用作未来缝隙透水路面设计的参照数据,包括新型路面砖,路基的垫层、基层和底基层材料,填缝砂子粘合剂,一些再生材料的应用,路面坡度,等等对路面雨水径流的影响。Kalle Loimula Emma Niemelinen Hannele Kuosa 崔玉忠 2015建筑砌块与砌块建筑2015,,6:3
2Impacts of common factors of life style on serum liver enzymes显示文摘AIM: To investigate the impacts of gender, age and factors of life style(alcohol, overweight, coffee and smoking) on serum liver enzymes.METHODS: Serum alanine aminotransferase(ALT) and gamma-glutamyltransferase(GGT) were measured from 6269 apparently healthy individuals(2851 men, 3418 women, mean age 45 ± 12 years, range 25-74 years) in a national cross-sectional health survey. All subjects underwent detailed clinical examinations and interviews including the amount and pattern of alcoholuse, coffee consumption and smoking habits. RESULTS: In this population with a mean ± SD alcohol consumption of 65 ± 105 g/wk and body mass index(BMI) of 26.1 ± 4.3 kg/m2, both ALT and GGT were significantly influenced by alcohol use(P < 0.001) and BMI(P < 0.001), whereas smoking increased only GGT(P < 0.001). A significant effect of age on ALT was seen in men(P < 0.001) whereas not in women. Significant two-factor interactions of alcohol use in men were observed with age(ALT: P < 0.01; GGT: P < 0.001) and BMI(GGT: P < 0.05). For ALT, a significant interaction also occurred between BMI and age(P < 0.005). In contrast, women showed significant interactions of alcohol use with BMI(GGT: P < 0.05), smoking(GGT: P < 0.001), and coffee consumption(GGT: P < 0.001). CONCLUSION: Life-style associated changes in liver enzymes may reflect health risks, which should be considered in the definition of normal limits for liver enzymes.Joanna Danielsson Pivikki Kangastupa Tiina Laatikainen Mauri Aalto Onni Niemel 2014World Journal of Gastroenterology2014,20,33:2
3Epithelial cell proliferation and glandular atrophy in lymphocytic gastritis: Effect of H pylori treatment显示文摘AIM: Lymphocytic gastritis is commonly ass ociated with Helicobacter pylori infection. The presence of glandular atrophy and foveolar hyperplasia in lymphocytic gastritis suggests abnormalities in cell proliferation and differentiation,forming a potential link with the suspected association with gastric cancer. Our aim was to compare epithelial cell proliferation and morphology in H pylori associated lymphocytic gastritis and H pylori gastritis without features of lymphocytic gastritis,and to evaluate the effect of H pylori treatment.METHODS: We studied 14 lymphocytic gastritis patients with H pylori infection. For controls, we selected 14 matched dyspeptic patients participating in another treatment trial whose H pylori infection had successfully been eradicated.Both groups were treated with a triple therapy and followed up with biopsies for 6-18 months (patients) or 3 months (controls). Blinded evaluation for histopathological features was carried out. To determine the cell proliferation index,the sections were labeled with Ki-67 antibody.RESULTS: Before treatment, lymphocytic gastritis was characterized by foveolar hyperplasia (P=0.001) and glandular atrophy in the body (P=0.008), and increased proliferation in both the body (P=0.001) and antrum (P=0.002). Proliferation correlated with foveolar hyperplasia and inflammation activity. After eradication therapy, the number of intraepithelial lymphocytes decreased in the body (P=0.004)and antrum (P=0.065), remaining higher than in controls (P<0.001). Simultaneously, the proliferation index decreased in the body from 0.38 to 0.15 (P=0.043), and in the antrum from 0.34 to 0.20 (P=0.069), the antral index still being higher in lymphocytic gastritis than in controls (P=0.010).Foveolar hyperplasia and glandular atrophy in the body improved (P=0.021), reaching the non-LG level.CONCLUSION: In lymphocytic gastritis, excessive epithelial cell proliferation is predominantly present in the body, where it associates with foveolar hyperplasia and glandular atrophy.These characteristic changes of lymphocytic gastritis are largely related to H pylori infection, as shown by their improvement after eradication. However, some residual deviation was still seen in lymphocytic gastritis, indicating either an abnormally slow improvement or the presence of some persistent abnormality.Johanna M.Mkinen Seppo Niemel Tuomo Kerola Juhani Lehtola Tuomo J.Karttunen 2003World Journal of Gastroenterology2003,9,12:2
