Effect of oligofructose on resistance to postoperative high-fat diet-induced damage of metabolism in diabetic rats after sleeve gastrectomy

作者： Wei - Hong Cao, Sen hu, Jia- Ke Chai, Yi LU, Zhi - yong sheng

The aim of this study was to replicate an animal model of multi - organ dysfunction syndrome (MODS) induced by partial ischemia and reperfusion of the intestine. One hundred white rabbits were divided into 4 groups: hemorrhagic shock , intestine partial ischemia and reperfusion (I/R), sham operation, and normal groups. According to the changes in superior mesenteric artery (SMA) blood flow during hemorrhagic shock, the SMA was partially blocked with a self-designed instrument in order to replicate I/R injury to the intestine with a reduction in SMA blood flow to 50% and 70%, being maintained for 4 hours and 6 hours. The changes in functions and pathology of the intestine, heart, liver and kidney were observed. The SMA blood flow was reduced dramatically during hemorrhagic shock. When the SMA blood flow was blocked to 50% for 4 hours, multiple organs dysfunction could be produced, and the mortality and morbidity of MODS in this model were about 30% . Ischemia and reperfusion (SMA blood flow blocked by 50%, lasting for 4 hours) of the intestine could induce MODS, and it was a suitable model in simulating post - traumatic MODS.

在经典项目组合选择问题的基础上,建立了不确定条件下多期滚动项目组合选择模型,以各期获利最大为优化目标,以企业战略需求与所选项目合成战略贡献之间的均衡匹配性和资源增益性为关联约束条件.基于模糊理论提出了上方贴近度和下方贴近度概念,用以对战略均衡匹配性进行度量.应用可能性理论将所建模型转换为确定性模型.采用遗传算法对模型求解,并基于路径再连接(path relinking,PR)算法思想,设计了适合0-1编码的逐次替代法和逐次后移法进行局部搜索,获得了较好的求解效果.仿真测试显示,进行多期滚动项目组合选择时,在5期以内可以保证获利的稳定性,获利波动期在第6-8期,可以帮助企业确定最佳战略调整期.各期不同类型的项目选择数量也具有较明显的周期性变化规律.研究结果具有实践指导意义.

Rice （Oryza safiva L.） is highly susceptible to the rhizosphere salinity than other cereals. High sensitivity has been ob- served, mainly at vegetative and reproductive stages in rice. It is the duty of plant physiologists to comprehend the growth, development, and physiological processes of rice plants under stress. This paper includes the overview of rice growth and developmental processes influenced by salt stress and the regulation pathways involved in these processes. It also includes the promising salt tolerance strategies, i.e., genetic modification techniques, agronomic practices to improve rice growth, yield; and role of phytohormones and their management, especially inhibition of ethylene biosynthesis by using inhibitors 1-methylcyclopropene （1-MCP）. Rice cultivation may be a first choice for improvement of salt tolerance through plant growth regulators and improved cultivation techniques. This study will significantly improve the understanding toward low rice grain yield and poor rice resistance under salt stress and will also stream scientific knowledge for effective utilization of salt affected soils by using different regulating ways.
