3Challenges in diagnosing mesenteric ischemia显示文摘Early identification of acute mesenteric ischemia (AMI) is challenging. The wide variability in clinical presentation challenges providers to make an early accurate diagnosis. Despite major diagnostic and treatment advances over the past decades, mortality remains high. Arterial embolus and superior mesenteric artery thrombosis are common causes of AMI. Non-occlusive causes are less common, but vasculitis may be important, especially in younger people. Because of the unclear clinical presentation and non-specific laboratory findings, low clinical suspicion may lead to loss of valuable time. During this diagnostic delay, progression of ischemia to transmural bowel infarction with peritonitis and septicemia may further worsen patient outcomes. Several diagnostic modalities are used to assess possible AMI. Multi-detector row computed tomographic angiography is the current gold standard. Although computed tomographic angiography leads to an accurate diagnosis in many cases, early detection is a persistent problem. Because early diagnosis is vital to commence treatment, new diagnostic strategies are needed. A non-invasive simple biochemical test would be ideal to increase clinical suspicion of AMI and would improve patient selection for radiographic evaluation. Thus, AMI could be diagnosed earlier with follow-up computed tomographic angiography or high spatial magnetic resonance imaging. Experimental in vitro and in vivo studies show promise for alpha glutathione S transferase and intestinal fatty acid binding protein as markers for AMI. Future research must confirm the clinical utility of these biochemical markers in the diagnosis of mesenteric ischemia.Teun C van den Heijkant Bart AC Aerts Joep A Teijink Wim A Buurman Misha DP Luyer 2013World Journal of Gastroenterology2013,19,9:31
4大别造山带磷灰石裂变径迹(AFT)年代学研究显示文摘大别山花岗岩与变质岩的AFT热年代分布于96.4~41.9Ma之间,围限径迹长度为11.5~14.0μm.热年代代表岩石差异通过100℃等温面时的冷却时代,这种差异性主要受控于NNE向区域构造,在北淮阳与合肥盆地,沉积岩样品(侏罗纪~早第三纪)AFT年代为128.8~62.0Ma,围限径迹长度为8.6~11.9μm,它们更多反映盆地埋藏加热的信息,合肥盆地与大别造山带之间存在构造耦合关系,95~90Ma属于大别山构造推隆取代伸展热窿的转折期,其成因可能与西太平洋域汇聚变化特性有关:商城-麻城与郯-庐两断裂之间左旋差异走滑与构造推隆作用,使得大别腹地伸展热窿在晚白垩世急剧萎缩.早第三纪时期,受西太平洋域汇聚速率急剧下降的影响,欧亚东缘表现出广泛的拉张环境,大别山60~40Ma带状热异常应与这种拉张作用有关;郯-庐热中心的冷却(70~40Ma)要比商城-麻城热中心(60~55Ma)缓慢,而大别腹地热隆区(60~40Ma)属于伸展热窿萎缩之残留.大别山早第三纪还遭受喜马拉雅山碰撞域的远场影响,这种影响多通过NWW向断裂来实现构造传递:进入渐新世一中新世,大别山冷却波动仍显现区域差异性,它们在时间上与南海盆地扩张、关闭事件相近.许长海 周祖翼 P.Van Den Haute R.A.Donelick J.De Grave 马昌前 P.W.Reiners 2004中国科学(D辑)2004,34,7:27

6Magnetic resonance imaging in breast cancer:A literature review and future perspectives显示文摘Early detection and diagnosis of breast cancer are essential for successful treatment. Currently mammography and ultrasound are the basic imaging techniques for the detection and localization of breast tumors. The low sensitivity and specificity of these imaging tools resulted in a demand for new imaging modalities and breast magnetic resonance imaging(MRI) has become increasingly important in the detection and delineation of breast cancer in daily practice. However, the clinical benefits of the use of pre-operative MRI in women with newly diagnosed breast cancer is still a matter of debate. The main additional diagnostic value of MRI relies on specific situations such as detecting multifocal, multicentric or contralateral disease unrecognized on conventional assessment(particularly in patients diagnosed with invasive lobular carcinoma), assessing the response to neoadjuvant chemotherapy, detection of cancer in dense breast tissue, recognition of an occult primary breast cancer in patients presenting with cancer metastasis in axillary lymph nodes, among others. Nevertheless, the development of new MRI technolo-gies such as diffusion-weighted imaging, proton spectroscopy and higher field strength 7.0 T imaging offer a new perspective in providing additional information in breast abnormalities. We conducted an expert literature review on the value of breast MRI in diagnosing and staging breast cancer, as well as the future potentials of new MRI technologies.Gisela LG Menezes Floor M Knuttel Bertine L Stehouwer Ruud M Pijnappel Maurice AAJ van den Bosch 2014World Journal of Clinical Oncology2014,5,2:25

9China’s 1-3-7 surveillance and response strategy for malaria elimination: Is case reporting, investigation and foci response happening according to plan?显示文摘Background:The China’s 1-3-7 strategy was initiated and extensively adopted in different types of counties(geographic regions)for reporting of malaria cases within 1 day,their confirmation and investigation within 3 days,and the appropriate public health response to prevent further transmission within 7 days.Assessing the level of compliance to the 1-3-7 strategy at the county level is a first step towards determining whether the surveillance and response strategy is happening according to plan.This study assessed if the time-bound targets of the 1-3-7 strategy were being sustained over time.Such information would be useful to improve implementation of the 1-3-7 strategy in China.Methods:This cross-sectional study involved country-wide programmatic data for the period January 1st 2013 to June 30th 2014.Data variables were extracted from the national malaria information system and included socio-demographic information,type of county,date of diagnosis,date of reporting,date of case investigation,case classification(indigenous,or imported,or unknown),focus investigation,date of reactive case detection(RACD),and date of indoor residual spraying(IRS).Summary statistics and proportions were used and comparisons between groups were assessed using the chi-square test.Level of significance was set at a P-value≤0.05.Results:Of a total of 5,688 malaria cases from 731 counties,there were 55(1%)indigenous cases(only in Type 1 and Type 2 counties)and 5,633(99%)imported cases from all types of counties.There was no delay in reporting malaria cases by type of county.In terms of case investigation,97.5%cases were investigated within 3 days with the proportion of delays(1.5%)in type 2 counties,being significantly lower than type 1 counties(4.1%).Regarding active foci,96.4%were treated by RACD and/or IRS.Conclusions:The performance of 1-3-7 strategy was encouraging but identified some challenges that if addressed can further improve implementation.Shui-Sen Zhou Shao-Sen Zhang Li Zhang Aafje ECRietveld Andrew RRamsay Rony Zachariah Karen Bissell Rafael Van den Bergh Zhi-Gui Xia Xiao-Nong Zhou Richard ECibulskis 2015Infectious Diseases of Poverty2015,4,1:21

12The Bedload Movement in the Changjiang Estuary显示文摘- Sandwaves in the Changjiang estuary were measured with a shallow sediment profiler and an echosounder from 1978 to 1988. The data, together with grain size and bedform of sediment indicates that the bedload movement by rolling and saltation is of great significance to sediment transport and is the principal factor responsible for sandwave and sandbody development in the estuary. The sandwaves were found well-developed, which is related to the tidal range and the velocity of ebb current. However, the further growth is restricted by strong flood current prevailing in the estuary. Because of the significant bedload, the sandbodies shift obviously and frequently, and sometimes the exchange of position occurs between the sandbodies and tidal channels. As a result, ships are regularly forced to change their navigation course.Li Jiufa, Shi Weirong, Shen Huanting Xu Haigen and Doeke Eisma Associate Professor, Institute of Estuarine & Coastal Research (1ECR), East China Normal University, Shanghai200062 Professor, IECR, East China Normal University, Shanghai 200062 Professor, Netherlands Institute for Sea Research, P.

14Unusual high-density and saline aqueous inclusions in ultrahigh pressure metamor- phic rocks from Sulu terrane in eastern China显示文摘Primary high-density fluid inclusions were identified in garnet from ultrahigh pressure eclogite in the southern part of the Sulu terrane. They occur isolatedly or in cluster together with relatively low-density two-phase inclu-sions. The eutectic temperature of the inclusions is as low as ≤ -52℃. A bubble was nucleated in a liquid inclusion dur-ing the specific stage of cyclic cooling-heating runs, and the liquid-gas homogenization temperature was measured to be ≤-12.5℃. The composition of the inclusions modeled by the system CaCl2-NaCl-H2O, yields the fluid density of 1.27g/cm3 that corresponds to a pressure of ca. 2.4 GPa at thetemperature of peak eclogite-facies metamorphism, close tothe ultrahigh pressure metamorphic conditions. During theexhumation of the eclogite the inclusions reacted with thehost mineral, forming hydrous silicate minerals that resulted in lowering of the fluid density and its transformation to multi-phase inclusions.SHEN Kun ZHANG Zeming A.M.van den Kerkhof XIAO Yilin XU Zhiqin J.Hoefs 2003Chinese Science Bulletin2003,48,18:14
15大别山双河和碧溪岭超高压变质岩流体包裹体研究显示文摘对大别山双河和碧溪岭含柯石英榴辉岩和硬玉石英岩进行了详细的流体包裹体研究。根据流体包裹体的成分和盐度的不同 ,可以划分出至少五种类型不同的气液包裹体 :( 1) N2 包裹体 ;( 2 )高盐度流体包裹体 ;( 3) CO2 包裹体 ;( 4) CO2 -H2 O包裹体 ;( 5 )低盐度流体包裹体。N2 包裹体仅见于含柯石英榴辉岩 ,而高盐度流体包裹体则几乎存在于所有的榴辉岩和硬玉石英岩中。 CO2 包裹体沿榴辉岩中微剪切带分布 ,或存在于强变形的硬玉石英岩中 ,而低盐度流体包裹体分布较为局限。N2 和高盐度流体被认为是超高压变质作用平衡的产物 ,来源于变质前的古孔隙流体。而且榴辉岩中含有一系列盐度不同的流体显微域 ,其大小与矿物颗粒相当。在板块折返过程中 ,包裹体中流体可能发生迁移 ,但是不会超出寄主晶体的范围。CO2流体明显是外来的 ,可能来自共生大理岩或含碳酸盐的变质沉积岩。这与菱镁矿和柯石英等共生组合所指示的进变质过程中大理岩不存在脱碳反应的结论相一致。而低盐度流体则可能系顶峰变质矿物分解而成 。傅斌 肖益林 J L R Touret A M Van den Kerkhof JHoefs 郑永飞 2000岩石学报2000,16,1:14
16成都平原蔬菜生产中灌溉水对农药渗漏的影响研究显示文摘针对成都平原蔬菜生产中大量施用农药、大量灌水的特点,首次在国内应用欧洲官方成熟的农药评估模型——PEARL模型,研究评估了成都平原当前蔬菜生产中的灌溉方式对两种不同特性农药的渗漏的影响。杀毒矾(土壤吸附力(KOM)为0 L/kg,半衰期(DT50)为80 d)在没有灌溉条件下,其渗出土体时的最大质量浓度是190μg.L-1,而有灌溉条件下其渗出质量浓度则可达523μg.L-1,是没有灌溉条件下的2.75倍。三唑磷(KOM为200 L.kg-1,DT50为60 d)在没有灌溉条件下,其渗出土体时的最大质量浓度是0.025μg.L-1,而有灌溉条件下其渗出质量浓度为0.13μg.L-1,比没有灌溉时提高了4.2倍。不管有没有灌溉三唑磷在该地区对地下水的污染风险都很小,而杀毒矾的风险则很高。因此,农药的化学特性是影响农药渗漏的最重要的因子。在蔬菜生产中应尽量选用被土壤吸附力强、半衰期短的农药,例如:三唑磷;农药在土壤中的移动载体是土壤水,不合理的灌溉会大大地加大农药淋溶,应当多使用微喷、滴灌等节水灌溉措施,减少使用漫灌等耗水多的原始灌溉方式。林超文 陈一兵 黄晶晶 Rik van den Bosch Mechteld M.S.ter Horst 2005生态环境2005,14,5:12
17Treatment of acute periprosthetic infections with prosthesis retention: Review of current concepts显示文摘Periprosthetic joint infection(PJI) is a devastating complication after total joint arthroplasty, occurring in approximately 1%-2% of all cases. With growing populations and increasing age, PJI will have a growing effect on health care costs. Many risk factors have been identified that increase the risk of developing PJI, including obesity, immune system deficiencies, malignancy, previous surgery of the same joint and longer operating time. Acute PJI occurs either postoperatively(4 wk to 3 mo after initial arthroplasty, depending on the classification system), or via hematogenous spreading after a period in which the prosthesis had functioned properly. Diagnosis and the choice of treatment are the cornerstones to success. Although different definitions for PJI have been used in the past, most are more or less similar and include the presence of a sinus tract, blood infection values, synovial white blood cell count, signs of infection on histopathological analysis and one ormore positive culture results. Debridement, antibiotics and implant retention(DAIR) is the primary treatment for acute PJI, and should be performed as soon as possible after the development of symptoms. Success rates differ, but most studies report success rates of around 60%-80%. Whether single or multiple debridement procedures are more successful remains unclear. The use of local antibiotics in addition to the administration of systemic antibiotic agents is also subject to debate, and its pro's and con's should be carefully considered. Systemic treatment, based on culture results, is of importance for all PJI treatments. Additionally, rifampin should be given in Staphylococcal PJIs, unless all foreign material is removed. The most important factors contributing to treatment failure are longer duration of symptoms, a longer time after initial arthroplasty, the need for more debridement procedures, the retention of exchangeable components, and PJI caused by Staphylococcus(aureus or coagulase negative). If DAIR treatment is unsuccessful, the following treatment option should be based on the patient health status and his or her expectations. For the best functional outcome, one- or two-stage revision should be performed after DAIR failure. In conclusion, DAIR is the obvious choice for treatment of acute PJI, with good success rates in selected patients.Jesse WP Kuiper Robin Tjeenk Willink Dirk Jan F Moojen Michel PJ van den Bekerom Sascha Colen 2014World Journal of Orthopedics2014,5,5:12
