1Epidural anesthesia improves pancreatic perfusion and decreases the severity of acute pancreatitis显示文摘AIM: To study the safety of epidural anesthesia(EA),its effect on pancreatic perfusion and the outcome of patients with acute pancreatitis(AP).METHODS: From 2005 to August 2010,patients with predicted severe AP [Ranson score ≥ 2,C-reactive protein > 100 or necrosis on computed tomography(CT)] were prospectively randomized to either a group receiving EA or a control group treated by patientcontrolled intravenous analgesia. Pain management was evaluated in the two groups every eight hours using the visual analog pain scale(VAS). Parameters for clinical severity such as length of hospital stay,use of antibiotics,admission to the intensive care unit,radiological/clinical complications and the need for surgical necrosectomy including biochemical data were recorded. A CT scan using a perfusion protocol was performed on admission and at 72 h to evaluate pancreatic blood flow. A significant variation in blood flow was defined as a 20% difference in pancreatic perfusion between admission and 72 h and was measured in the head,body and tail of the pancreas.RESULTS: We enrolled 35 patients. Thirteen were randomized to the EA group and 22 to the control group. There were no differences in demographic characteristics between the two groups. The Balthazar radiological severity score on admission was higher in the EA group than in the control group(mean score 4.15 ± 2.54 vs 3.38 ± 1.75,respectively,P = 0.347) and the median Ranson scores were 3.4 and 2.7 respectively(P = NS). The median duration of EA was 5.7 d,and no complications of the epidural procedure were reported. An improvement in perfusion of the pancreas was observed in 13/30(43%) of measurements in the EA group vs 2/27(7%) in the control group(P = 0.0025). Necrosectomy was performed in 1/13 patients in the EA group vs 4/22 patients in the control group(P = 0.63). The VAS improved during the first ten days in the EA group compared to the control group(0.2 vs 2.33,P = 0.034 at 10 d). Length of stay and mortality were not statistically different between the 2 groups(26 d vs 30 d,P = 0.65,and 0% for both respectively).CONCLUSION: Our study demonstrates that EA increases arterial perfusion of the pancreas and improves the clinical outcome of patients with AP.Samira M Sadowski Axel Andres Philippe Morel Eduardo Schiffer Jean-Louis Frossard Alexandra Platon Pierre-Alexandre Poletti Leo Bühler 2015World Journal of Gastroenterology2015,21,43:21
2增施氮肥和地面管理对酸樱桃园土壤营养状况的影响显示文摘在一个连续进行了 8年N肥定位试验的酸樱桃园,调查了每年施用 N60 kg· hm^(-2)和行间生草制对土壤营养状况的影响。结果表明:在肥沃土壤里NH_4~+是速效N的主要存在形式,而NO_3~-的含量很低。生草地土壤中含有较多的 NH_4~-,而清耕带土壤中含有较多的 NO_3~-。施肥增加土壤速效 N的含量。土壤 NO_3~-的季节性变化表明 5至 6月份土壤中 NO_3~-的含量高,而花前和 7月份土壤中 NO_3~-含量低。 P、K在清耕带 10 cm以下土壤的含量低于生草地土壤,但在 0~ 10cm土层中K的含量高于生草地。P的含量不受影响。施N减少了土壤P、K的含量。土壤中Mg的含量分布均匀,不受施N和地面管理制度的影响。杨朝选 Andrzej Sadowski Ewa Jadczuk 2000果树科学2000,17,1:14

11Effects of Rhodiola rosea supplementation on mental performance,physical capacity,and oxidative stress biomarkers in healthy men显示文摘Purpose: The objective of this study was to investigate the effects of chronic Rhodiola rosea(R. rosea) supplementation on mental and physical performance, as well as hormonal and oxidative stress biomarkers.Methods: Twenty-six healthy male students received either R. rosea extract(600 mg/day; RR) or placebo(PL) in a randomized double-blind trial. Prior to supplementation(Term I) and following 4 weeks of supplementation(Term II), the students underwent psychomotor tests for simple and choice reaction time, included in the Vienna Test System. Also, the subjects performed VO2 peaktest. Blood samples were obtained before and after the test to measure the hormonal profile(cortisol, testosterone, and growth hormone), as well as the biomarkers of oxidative stress(lipid hydroperoxides, total antioxidant capacity, and superoxide dismutase) and muscle damage(creatine kinase).Results: R. rosea ingestion shortened reaction time and total response time. Moreover, a greater relative increase in the number of correct responses was observed in RR group as compared to the PL group. No changes in endurance exercise capacity and hormonal profile were observed after R. rosea ingestion. R. rosea ingestion raised plasma total antioxidant capacity. It did not, however, affect other measured parameters.Conclusion: Chronic R. rosea ingestion does not affect physical performance, but can improve the results of some psychomotor tests(simple and choice reaction time) in young, healthy, and physically active men. The improvements in mental performance, however, at least in our study,seem not to be related to changes in cortisol release or antioxidant activity of R. rosea extract. Thus, the specific mechanisms responsible for these effects still need to be elucidated.ewa jówko jerzy sadowski barbara dlugolecka dariusz gierczuk benedykt opaszowski igor ciesliński 2018Journal of Sport and Health Science2018,7,4:2
12Gene Networks in Plant Ozone Stress Response and Tolerance显示文摘For many plant species ozone stress has become much more severe in the last decade. The accumulating evidence for the significant effects of ozone pollutant on crop and forest yield situate ozone as one of the most important environmental stress factors that limits plant productivity worldwide. Today, transcriptomic approaches seem to give the best coverage of genome level responses. Therefore, microarray serves as an invaluable tool for global gene expression analyses, unravelling new information about gene pathways, in-species and cross-species gene expression comparison, and for the characterization of unknown relationships between genes. In this review we summarize the recent progress in the transcriptomics of ozone to demonstrate the benefits that can be harvested from the application of integrative and systematic analytical approaches to study ozone stress response. We focused our consideration on microarray analyses identifying gene networks responsible for response and tolerance to elevated ozone concentration. From these analyses it is now possible to notice how plant ozone defense responses depend on the interplay between many complex signaling pathways and metabolite signals.Agnieszka Ludwikow Jan Sadowski 2008Journal of Integrative Plant Biology2008,50,10:2
