1二尖瓣病变定位经食道超声检查与术中发现的对照研究显示文摘目的:应用经食道超声心动图序列二尖瓣病变定位切面与术中发现进行对照研究,寻找对应二尖瓣不同小叶分区的相应切面及标准化操作规程,以供临床决策及提高手术成功率。方法:二尖瓣脱垂并伴有中度以上的二尖瓣反流拟行外科手术患者53例。术前行食道超声检测瓣膜病变类型与小叶分区定位,与术中发现进行对照。二尖瓣的解剖定位采用Carpentier命名法,将前叶分为A1、A2及A3,后叶分为P1、P2及P3。术前1周及术中食道超声应用中食道四腔心切面、中食道5腔心切面、显示冠状静脉窦的短四腔心切面、两腔心切面、二尖瓣交界区两腔心切面、中食道左心室长轴切面及胃底左心室短轴切面进行二尖瓣病变的小叶分区定位。外科医生术中记录二尖瓣瓣膜脱垂、腱索断裂等病理类型及A1、A2及A3;P1、P2及P3病变部位。结果:46例资料完整的患者276个小叶被分析。在7个可以显示二尖瓣小叶分区定位的切面中,中食道五腔心切面、中食道四腔心切面、显示冠状静脉窦的短四腔切面、三腔心切面及结合彩色血流的胃底左心室短轴切面与术中发现的吻合率较高。结论:通过食道超声选择序列合理的切面可以在二尖瓣手术前进行较为准确的病变小叶分区定位,为外科手术,尤其是二尖瓣成形术提供必要的术前资料。何怡华 李治安 谷孝艳 韩建成 陈健 Michael CK John Victor N 2009心肺血管病杂志2009,28,5:26
2气候变化和紫外线辐射对北极淡水鱼类及溯河产卵鱼类渔业的影响显示文摘北极淡水鱼类和洄游鱼类渔业为北方经济做出了重大贡献。但是,对于淡水水体,气候变化和增长的紫外线辐射对渔业产生的巨大影响有3个方面:可获鱼的数量、质量和捕捞成功率。因此,在这些影响发生作用之际,可能需要实质有效的适应行为以引导北极未来的渔业走向可持续性。当务之急是为商业渔业选择灵活和快速反应的'适宜管理'方式;改变生计渔业的当地土地和资源利用模式;改变很多休闲渔业的特性、管理方式和地点。总的来说,在气候变化及其对北极淡水水域和生物区影响的复杂性和不确定性情况下,为保证生态系统和主导鱼种有足够的恢复力和应对将来变化的能力,需要对渔业的各个方面实施更保守的管理办法。James D.Reist Frederick J.Wrona Terry D.Prowse J.Brian Dempson Michael Power Günter Kck Theresa J.Carmichael Chantelle D.Sawatzky Hannu Lehtonen Ross F.Tallman 曾首英 2006AMBIO-人类环境杂志2006,35,7:4

8Urbanization in China from the end of 1980s until 2010 – spatial dynamics and patterns of growth using EO-data显示文摘Urbanization in China has been experiencing a remarkable dynamism in the past 40 years.The most evident implication of urbanization is the physical growth of cities.We analyze urban land growth rates and changes in spatial urban forms from the end of the 1980s to 2010 based on the authoritative National Land Use/Cover Database of China.We present new spatial measures that describe‘urban land growth types’and‘fluctuations in urban land growth’within the monitoring time span with a temporal interval of five-year steps.We evaluate the correlations between urban land growth rates and socioeconomic data.Results show that(1)distinct characteristics exist on the spatiotemporal evolutions of urban land growth rates in terms of area and perimeter,e.g.coastal areas exhibit the most dramatic growth rates;(2)the spatial distribution characteristics of‘urban land growth types’and‘fluctuations in urban land growth’follow similar spatial patterns across China,e.g.significant differences exist between the eastern region and other regions;and(3)a moderate correlation exists between urban area growth rate and urban population growth rate at an R2 of 0.37.By contrast,we determine no significant correlation between urban area growth rate and tertiary industry value growth rate.Lifeng Shia Hannes Taubenböck Zengxiang Zhang Fang Liu Michael Wurm 2019International Journal of Digital Earth2019,12,1:1
9PillCamColon2 after incomplete colonoscopy-A prospective multicenter study显示文摘AIM To evaluate the ability of PillCamColon2 to visualize colonic segments missed by incomplete optical colonoscopy(OC) and to assess the diagnostic yield.METHODS This prospective multicentre study included 81 patients from nine centres who underwent second-generation colon capsule endoscopy(CCE) following incomplete OC performed by an experienced gastroenterologist(> 1000 colonoscopies). Patients with stenosis were excluded. According to patient preferences, CCE was performed the following day(protocol A) after staying on clear liquids and 0.75 L Moviprep in the morning or within 30 d after new split-dose Moviprep(protocol B). Boosts consisted of 0.75 L and 0.25 L Moviprep, and phospho-soda was given as a rescue if the capsule was not excreted after seven hours.RESULTS Seventy-four patients were analysed(51% of them in group A; 49% in group B). Bowel cleansing was adequate in 67% of cases, and CCE could visualize colonic segments missed by incomplete colonoscopy in 90% of patients under protocol A and 97% of patients under protocol B(P = 0.35, n.s.). Significant polyps including adenocarcinoma were detected in 24% of cases. Detection rates for all polyps and significant polyps per patient were similar in both protocols. Polyps were found predominantly in the right colon(86%) in segments that were not reached by OC. Extracolonic findings-such as reflux esophagitis, suspected Barrett esophagus, upper GI-bleeding, gastric polyps, gastric erosions and angiectasia-were detected in eight patients. Pill Cam Colon2 capsule was retained in the ileum of one patient(1.4%) without symptoms and removed during an uneventful resection for unknown Crohn's disease that was diagnosed as the cause of anemia, which was the indication for colonoscopy. CCE was well tolerated. One patient suffered from selflimiting vomiting after consuming the phospho-soda.CONCLUSION Second-generation CCE using a low-volume preparation is useful after incomplete OC, and it allows for the detection of additional relevant findings, but cleansing efficiency could be improved.Peter Baltes Marc Bota Jorg Albert Michael Philipper Hans-Georg Horster Friedrich Hagenmüller Ingo Steinbrück Ralf Jakobs Matthias Bechtler Dirk Hartmann Horst Neuhaus Jean-Pierre Charton Rupert Mayershofer Horst Hohn Thomas Rosch Stefan Groth Tanja Nowak Peter Wohlmuth Martin Keuchel 2018World Journal of Gastroenterology2018,24,31:1
