1长期保护性耕种方式对农田表层土壤性质的影响显示文摘研究了不同耕种方式对澳大利亚同一地区3种土壤表层(0-5cm)理化性质的作用,以揭示保护性耕作对土壤质量恢复的影响。结果表明:免耕穴播/保留残茬(DD/SR)、多年生人工草地(PP)和自然草地(NP)表层土壤的〉2mm水稳性团聚体含量、全氮、有机碳含量、田间持水量均显著高于其相应对照传统耕作/秸秆焚烧(CC/SB)、人工草地/作物轮作(PPC)和耕作(CT)的;土壤全氮含量、田间持水量分别与有机碳含量之间有极显著的正相关关系(r=0.994**,r=0.996**,n=6),而受土壤质地等因素的影响较小;在同一类型的土壤上,土壤有机碳含量与水稳定性团聚体含量之间存在显著的相关性;在不同试验区,耕作措施对表层土壤容重和孑L隙分布的影响存在较大差异;秸秆焚烧和施用石膏对表层土壤的pH及交换性阳离子含量有较大的影响。研究表明长期保护性耕作、草田轮作或多年生草地有利于提高表层土壤有机碳含量和结构稳定性,从而改善土壤的供肥供水能力。张国盛 K Y Chan G D Li D P Heenan 2008生态学报2008,28,6:45
2Protective effects of trilinolein extracted from Panax notoginseng against cardiovascular disease显示文摘Trilinolein is a triacylglycerol purified from a commonly used traditional Chinese medicine Panax notoginseng,Trilinolein has been reported to provide a number of beneficial effects including reducing thrombogenicity and arrhythmias and increasing erythrocyte deformability.Additionally,trilinolein has been reported to be an antioxidant,which can counteract free radical damage associated with atherogenesis,and myocardial damage seen with ischaemia and reperfusion.These pharmacologic effects may explain the perceived benefits derived from treating circulatory disorders with the herb over the centuries.Paul CHAN G Neil THOMAS Brian TOMLINSON 2002Acta Pharmacologica Sinica2002,23,12:45
3Relationship between obesity and cardiovascular risk factors in elderly Chinese subjects显示文摘Objective To investigate the relative effects of degree and distribution of body fat with several cardiovascular disease (CVD) risk factors in elderly Chinese subjects.Methods One-hundred and thirty-five elderly Chinese individuals (age range, 60-65 y) without any history of significant renal, hepatic or cardiac disease were recruited. Seated blood pressure, anthropometric and fasting plasma biochemical parameters were measured. Student’s t-test was used to compare the differences in biochemical and anthropometric markers between cohorts.Results Males were heavier (64.6±8.6, 57.2±8.2?kg, P<0.001), taller (1.65±0.06, 1.51± 0.05 m, P<0.001) and their greater body fat was predominantly deposited centrally (Waist-to-hip ratio, 0.91±0.06, 0.88±0.07, P<0.05). Females were more generally obese with increased body mass index (BMI, 23.8±4.6, 25.0±3.5 kg/m 2, P<0.05) and percentage body fat [26.3% (24.5%-28.1%) vs 37.2% (36.0%-38.9%), P<0.001] than the males. However, despite an 11% higher proportion of body fat in females, no significant differences were identified in blood pressure, lipid profile, indices of insulin resistance or albumin-to-creatinine ratios.Conclusion It is likely that central adiposity contributes disproportionately to these metabolic disorders in males even though they are much leaner than elderly Chinese females.G Neil THOMAS 赵海潞 马艳青 Wilson YS LEUNG Juliana CN CHAN Brian TOMLINSON Julian AJH CRITCHLEY 梁润成 陈重娥 汤宁信 郭志良 2002Chinese Medical Journal2002,,6:11
4Diagnosis,severity stratification and management of adult acute pancreatitis–current evidence and controversies显示文摘Acute pancreatitis(AP)is a disease spectrum ranging from mild to severe with an unpredictable natural course.Majority of cases(80%)are mild and self-limiting.However,severe AP(SAP)has a mortality risk of up to 30%.Establishing aetiology and risk stratification are essential pillars of clinical care.Idiopathic AP is a diagnosis of exclusion which should only be used after extended investigations fail to identify a cause.Tenets of management of mild AP include pain control and management of aetiology to prevent recurrence.In SAP,patients should be resuscitated with goal-directed fluid therapy using crystalloids and admitted to critical care unit.Routine prophylactic antibiotics have limited clinical benefit and should not be given in SAP.Patients able to tolerate oral intake should be given early enteral nutrition rather than nil by mouth or parenteral nutrition.If unable to tolerate per-orally,nasogastric feeding may be attempted and routine post-pyloric feeding has limited evidence of clinical benefit.Endoscopic retrograde cholangiopancreatogram should be selectively performed in patients with biliary obstruction or suspicion of acute cholangitis.Delayed step-up strategy including percutaneous retroperitoneal drainage,endoscopic debridement,or minimal-access necrosectomy are sufficient in most SAP patients.Patients should be monitored for diabetes mellitus and pseudocyst.Kai Siang Chan Vishal G Shelat 2022World Journal of Gastrointestinal Surgery2022,14,11:3
