AIM： Pancreatic pseudocysts （PPC） as a complication of pancreatitis are approached only in the case of abdominal pain, infection, bleeding, and compression onto the gastrointestinal tract or biliary tree. METHODS： From 02/01/2002 to 05/31/2004, all con- secutive patients with symptomatic PPC who underwent an interventional endoscopic approach were evaluated in this pilot case-series study： Group （Gr.） Ⅰ-Primary percutaneous （external）, ultrasound-guided drainage. Gr. Ⅱ- Primary EUS-guided cystogastrostomy. Gr. Ⅲ-EUS-guided cystogastrostomy including intracystic necrosectomy. RESULTS：（=＂follow up＂： n = 27）： Gr. Ⅰ （n = 9; 33.3%）： No complaints （n = 3）; change of an external into an internal drainage （n = 4）; complications：（a） bleeding （n = 1） followed by 3 d at ICU, discharge after 40 d; （b） septic shock （n = 1） followed by ICU and several laparotomies for programmed lavage and necrosectomy, death after 74 d. Gr. Ⅱ （n = 13; 48.1%）： No complaints （n = 11）; external drainage （n = 2）; complications/problems out of the 13 cases： 2nd separate pseudocyst （n = 1） with external drainage （since no communication with primary internal drainage）; infection of the residual cyst （n = 1）＋ following external drainage; spontaneous PPC perforation （n = 1）＋ following closure of the opening of the cystogastrostomy using clips and subsequently ICU for 2 d. Gr. Ⅲ （n = 5; 18.5%）： No complaints in all patients, in average two endoscopic procedures required （range, 2-6）. CONCLUSION： Interventional endoscopic management of pancreatic pseudocysts is a reasonable alternative treatment option with low invasiveness compared to surgery and an acceptable outcome with regard to the complication rate （11.1%） and mortality （3.7%）, as shown by these initial study results.

The Role of Stationary and Transient Planetary Waves in the Maintenance of Stratospheric Polar Vortex Regimes in Northern Hemisphere Winter

引用

Advances in Atmospheric Sciences 2011年第1期28卷 187-194页

作者：李倩 Hans-F.graf 崔雪锋 Key Laboratory of Middle Atmosphere and Global Environment Observation Institute of Atmospheric PhysicsChinese Academy of Sciences School of GeoSciences University of Edinburgh Center for Atmospheric Science University of Cambridge State Key Laboratory of Earth Surface Processes and Resource Ecology College of Global Change and Earth System ScienceBeijing Normal University

Using 1958-2002 NCEPNCAR reanalysis data, we investigate stationary and transient planetary wave propagation and its role in wave-mean flow interaction which influences the state of the polar vortex （PV） in the stratosphere in Northern Hemisphere （NH） winter. This is done by analyzing the Eliassen-Palm （E-P） flux and its divergence. We find that the stationary and transient waves propagate upward and equatorward in NH winter, with stronger upward propagation of stationary waves from the troposphere to the stratosphere, and stronger equatorward propagation of transient waves from mid-latitudes to the subtropics in the troposphere. Stationary waves exhibit more upward propagation in the polar stratosphere during the weak polar vortex regime （WVR） than during the strong polar vortex regime （SVR）. On the other hand, transient waves have more upward propagation during SVR than during WVR in the subpolar stratosphere, with a domain of low frequency waves. With different paths of upward propagation, both stationary and transient waves contribute to the maintenance of the observed stratospheric PV regimes in NH winter.

The Interannual Variability of East Asian Winter Monsoon and Its Relation to the Summer Monsoon

引用

Advances in Atmospheric Sciences 2000年第1期17卷 48-60页

作者：陈文 Han-F.graf 黄荣辉 Institute of Atmospheric Physics Chinese Academy of Sciences China Max-Planck-Institute of Meteorology Hamburg Germany

Based on the NCEP/ NCAR reanalysis data the interannual variability of the East Asian winter mon-soon (EAWM) is studied with a newly defined EAWM intensity index. The marked features for a strong (weak) winter monsoon include strong (weak) northerly winds along coastal East Asia, cold (warm) East Asian continent and surrounding sea and warm (cold) ocean from the subtropical central Pacific to the trop-ical western Pacific, high (low) pressure in East Asian continent and low (high) pressure in the adjacent ocean and deep (weak) East Asian trough at 500 hPa. These interannual variations are shown to be closely connected to the SST anomaly in the tropical Pacific, both in the western and eastern Pacific. The results suggest that the strength of the EAWM is mainly influenced by the processes associated with the SST anom-aly over the tropical Pacific. The EAWM generally becomes weak when there is a positive SST anomaly in the tropical eastern Pacific (El Ni?o), and it becomes strong when there is a negative SST anomaly (La Ni?a). Moreover, the SST anomaly in the South China Sea is found to be closely related to the EAWM and may persist to the following summer. Both the circulation at 850 hPa and the rainfall in China confirm the connection between the EAWM and the following East Asian summer monsoon. The possible reason for the recent 1998 summer flood in China is briefly discussed too. Key words East Asian winter monsoon - Interannual variability - SST - Summer monsoon This study was supported by “ National Key Programme for Developing Basic Sciences” G1998040900 part 1, and by key project (KZ 952-S1-404) of Chinese Academy of Sciences.

It is easy to argue that open data are critical to enabling faster and more effective research *** this article,we describe the approach we have taken at Wiley to support open data and to start enabling more data to be FAIR data(Findable,Accessible,Interoperable and Reusable)with the implementation of four data policies:“Encourages”,“Expects”,“Mandates”and“Mandates and Peer Reviews Data”.We describe the rationale for these policies and levels of adoption so *** the coming months we plan to measure and monitor the implementation of these policies via the publication of data availability statements and data *** this information,we’ll be able to celebrate adoption of data-sharing practices by the research communities we work with and serve,and we hope to showcase researchers from those communities leading in open research.
