2基于GIS的黄土丘陵沟壑区作物生产潜力模拟研究显示文摘从 YIELD模型的来源、输入文件及基本参数、模型中作物生产力计算各个子模型以及计算流程 4个方面作了简单的叙述 ,以黄土丘陵沟壑区典型小流域晋西狼窝沟为例 ,在地理信息系统 ( GIS)技术支持下 ,应用 YIELD模型对该流域的作物生产潜力进行了模拟 ,并从作物类型、地类、耕作措施及气候条件 4个方面对影响该流域作物产量的因素进行分析。结果表明 ,该模型对不同作物的模拟产量在总体上与实测产量基本相符合 ,表明模型可以应用于黄土丘陵沟壑区的作物产量模拟之中 ;对于不同地类来说 ,坝地的土壤水分和肥力条件明显高于梯田和坡耕地 ,因而坝地的模拟产量也高于梯田和坡地 ,但三者之间的差距没有实测产量显著 ;耕作措施是提高作物生产力的有效途径 ,对地膜覆盖、梯田以及施肥等耕作措施的模拟产量表明 ,这 3种耕作措施均能有效的提高作物生产力 ,其产量提高率均平均在 85 %以上 ,其中以施肥对作物的增产作用最大 ,增产率高达 95 % ,这与实测产量资料基本一致 ;气候条件是影响作物生产的直接因素 ,模拟结果表明模型对降水量和温度等气候条件十分敏感 ,不同年份降水量和温度的差异将直接导致作物生产力的显著不同。对 YIELD模型的模拟结果分析表明 。李忠武 蔡强国 Scott Mitchell 唐政洪 Ferko Csillag 2002生态学报2002,22,3:12
3Clinical and economic consequences of pancreatic fistula after elective pancreatic resection显示文摘BACKGROUND:Postoperative pancreatic fistula is the main cause of morbidity after pancreatic resection.This study aimed to quantify the clinical and economic consequences of pancreatic fistula in a medium-volume pancreatic surgery center.METHODS:Hospital records from patients who had undergone elective pancreatic resection in our department were identified.Pancreatic fistula was defined according to the International Study Group on Pancreatic Fistula(ISGPF).The consequences of pancreatic fistula were determined by treatment cost,hospital stay,and out-patient follow-up until the pancreatic fistula was completely healed.All costs of the treatment are calculated in Euros.The cost increase index was calculated for pancreatic fistula of grades A,B,and C as multiples of the total cost for the no fistula group.RESULTS:In 54 months,102 patients underwent elective pancreatic resections.Forty patients(39.2%) developed pancreatic fistula,and 54 patients(52.9%) had one or more complications.The median length of hospital stay for the no fistula,grades A,B,and C fistula groups was 12.5,14,20,and 59 days,respectively.The hospital stay of patients with fistula of grades B and C was significantly longer than that of patients with no fistula(P<0.001).The median total cost of the treatment was 4952,4679,8239,and 30 820 Euros in the no fistula,grades A,B,and C fistula groups,respectively.CONCLUSIONS:The grading recommended by the ISGPF is useful for comparing the clinical severity of fistula and for analyzing the clinical and economic consequences of pancreatic fistula.Pancreatic fistula prolongs the hospital stay and increases the cost of treatment in proportion to the severity of the fistula.Filip Ceka Bohumil Jon Zdeněk ubrt Alexander Ferko 2013Hepatobiliary & Pancreatic Diseases International2013,12,5:7
4Pancreatic Castleman disease treated with laparoscopic distal pancreatectomy显示文摘BACKGROUND: Castleman disease is an uncommon lympho-proliferative disorder most frequently occurring in the mediastinum. Abdominal forms are less frequent, with pancreatic localization of the disease in particular being extremely rare. Only seventeen cases have been described in the world literature. METHOD: This report describes an interesting and unusual case of pancreatic Castleman disease treated with laparoscopic resection. RESULTS: A 48-year-old woman presented with epigastric pain. CT scan showed a well-encapsulated mass on the ventral border of the pancreas. Endosonography with fine needle aspiration biopsy was performed. Biopsy showed lymphoid elements and structures of a normal lymph node. The patient was treated with laparoscopic distal pancreatectomy. The pancreas was transected with a Ligasure device and the pancreatic stump was secured with a manual suture. One year after surgery the patient was complaint-free and showed no signs of recurrence of the disease. CONCLUSIONS: Laparoscopic distal pancreatectomy is a feasible and safe method for the treatment of lesions in the body and tail of the pancreas. Transection of the pancreas with a Ligasure device offers the advantages of low bleeding and low risk of pancreatic fistula.Filip ecka Alexander Ferko Bohumil Jon Zdeněk ubrt Petra Kaparová Rudolf Repák 2013Hepatobiliary & Pancreatic Diseases International2013,12,3:4
5Long-term survival of a patient after resection of a gastrointestinal stromal tumor arising from the pancreas显示文摘BACKGROUND:Gastrointestinal stromal tumors (GISTs) may arise in any part of the gastrointestinal tract;extragastrointestinal locations are extremely rare.Only a few cases of extragastrointestinal stromal tumor arising from the pancreas were reported.None of the reports described a long-term follow-up of the patients.METHOD:This report describes an interesting and unusual case of GIST arising from the pancreas.RESULTS:A 74-year-old female presented with a palpable abdominal mass.CT scan showed a large mass 11×8×4 cm originating from the tail of the pancreas.Percutaneous biopsy revealed a GIST predominantly with spindle cells,but some parts also contained epitheloid cells.The patient was treated by distal pancreatic resection with splenectomy.Immunohistochemistry of the tumor showed a staining pattern characteristic of GIST.The patient has achieved a long-term survival of five years and six months without any sign of recurrence of the disease.CONCLUSION:This is the first reported case of an extragastrointestinal stromal tumor arising from the pancreas treated surgically,with a long-term survival.Filip eka Bohumil Jon Alexander Ferko Zdeněk ubrt Dimitar H Nikolov Věra Tyová 2011Hepatobiliary & Pancreatic Diseases International2011,10,3:3
6Intra-abdominal drainage following pancreatic resection:A systematic review显示文摘AIM: To study all the aspects of drain management in pancreatic surgery.METHODS: We conducted a systematic review according to the PRISMA guidelines. We searched the Cochrane Central Registry of Controlled Trials,EMBASE,Web of Science,and Pub Med(MEDLINE) for relevant articles on drain management in pancreatic surgery. The reference lists of relevant studies were screened to retrieve any further studies. We included all articles that reported clinical studies on human subjects with elective pancreatic resection and that compared various strategies of intra-abdominal drain management,such as drain vs no drain,selective drain use,early vs late drain extraction,and the use of different types of drains. RESULTS: A total of 19 studies concerned with drain management in pancreatic surgery involving 4194 patients were selected for this systematic review. We included studies analyzing the outcomes of pancreatic resection with and without intra-abdominal drains,studies comparing early vs late drain removal and studies analyzing different types of drains. The majority of the studies reporting equal or superior results for pancreatic resection without drains were retrospective and observational with significant selection bias. One recent randomized trial reported higher postoperative morbidity and mortality with routine omission of intraabdominal drains. With respect to the timing of drain removal,all of the included studies reported superior results with early drain removal. Regarding the varioustypes of drains,there is insufficient evidence to determine which type of drain is more suitable following pancreatic resection. CONCLUSION: The prophylactic use of drains remains controversial. When drains are used,early removal is recommended. Further trials comparing types of drains are ongoing.Filip Cecka Martin Lovecek Bohumil Jon Pavel Skalicky Zdeněk Subrt Cestmír Neoral Alexander Ferko 2015World Journal of Gastroenterology2015,21,40:2
