目的探究绿原酸(chlorogenic acid,CGA)对中性粒细胞(neutrophil,NEU)功能及中性粒细胞胞外诱捕网(neutrophil extracellular traps,NETs)形成的影响及机制。方法从小鼠骨髓中分离并纯化NEU;将NEU与CGA共培养,通过CCK-8法筛选共培养适合的干预浓度;检测NEU迁移能力、髓过氧化物酶(MPO)以及脱颗粒弹性蛋白酶(NE)、基质金属蛋白酶9(MMP-9)的水平观察CGA对NEU功能的影响;免疫荧光法观察NETs的主要结构组蛋白H3及DNA骨架,以及检测NEU释放的游离DNA(cf-DNA)含量,观察NETs的形成情况;检测NEU产生的活性氧(ROS)水平,以确定CGA是否影响NEU释放NETs过程中的ROS的生成。结果CGA在浓度为100、200、400μmol·L^(-1)时对NEU活性有明显抑制作用(P<0.01)。与空白组(Blank)相比,CGA(100、200、400μmol·L^(-1))干预后,细胞迁移能力及MPO、NE、MMP-9分泌量增加(P<0.05),组蛋白H3及DNA骨架、cf-DNA的释放量明显增加(P<0.01),细胞产生的ROS也明显增加(P<0.01),上述作用在一定范围内具有浓度依赖性。结论CGA能够增强NEU功能及促进NETs的形成,可能与促进细胞内ROS水平增加有关。

Thermal hydraulic characteristics of helical coil once-through steam generator under ocean conditions

引用

Nuclear Science and Techniques 2022年第10期33卷 139-150页

作者： Tian-Ze Bai Chang-hong peng School of Nuclear Science and Technology University of Science and Technology of ChinaNo.96Jinzhai RoadBaohe DistrictHefei 230026China

Owing to its advantages of high heat transfer efficiency and compactness, the helical coil once-through steam generator(HCOTSG) can be used in floating nuclear power plants and has been widely used in the design of small modular reactors. The helical tubular geometric structure of the HCOTSG allows heat transfer and local flow changes to occur under complex ocean conditions. In this study, theoretical models of ocean conditions are added to the RELAP5/MOD3.3 code and verified. Using the modified RELAP5 code, the thermal–hydraulic characteristics of the HCOTSG under ocean conditions are simulated. The results show that under rolling conditions, the flow oscillation amplitudes of the single liquid-phase, twophase flow, and single gas-phase regions are different. A circular change in the horizontal position of the helical tube causes the fluctuation of the parameters to change periodically. A phase difference of approximately 3.9 s at a flow rate of 23 kg/s is observed in the flow fluctuation along the axial direction. The driving force, period, and amplitude of rolling significantly affect the flow fluctuation in the HCOTSG. In natural circulation, the flow in the HCOTSG is complex, and the primary-side flow fluctuation can reduce the trough of the flow oscillation at the helical tube by approximately 24.3%.

Chinese Journal of Electronics 2014年第1期23卷 87-92页

作者： TU Min WANG Jun peng hong SHI peng School of Electrical and Information Engineering Xihua University Center for Radio Administration and Technology Development Xihua University Department of Computing and Mathematical Sciences University of Glamorgan PontypriddCF37 1DL UK School of Engineering and Science Victoria University MelbourneVic 8001 Australia

Adaptive fuzzy spiking neural P systems(AFSN P systems) are a novel kind of computing models with parallel computing and learning ability. Based on our existing works, AFSN P systems are applied to deal with the fault diagnosis problems of power systems and the uncertainty of action messages about protective relays and breakers, and a new fault diagnosis model of power systems is proposed with simple reasoning process and fast speed with parallel processing capabilities. The effectiveness of the fault diagnosis model is verified by some examples of fault diagnosis. Furthermore, the learning ability of AFSN P systems can be applied to adjust the weights in the fault diagnosis model automatically.
