    Research on switch migration method based on minimum cost path by Yingxu LAI, Yewei PU, Jing LIU

    Published 2020-02-01
    “…In order to protect the controller,especially the controller in backbone network,from security threats and attacks,improve the security of the software-defined network (SDN) control plane,a switch migration algorithm based on minimum cost path was proposed.A load prediction module was added to the migration model,which executed a controller load prediction algorithm to obtain a load prediction matrix,and then a migration-target controller set was determined according to the load prediction matrix.The improved Dijkstra algorithm was used to determine the minimum cost path.According to the load state of the controller and the traffic priority of the switch to be migrated,the optimal migration switch set was determined.The problem of isolated nodes was solved that may occur during the migration process.The experimental results show that the migration timing of the algorithm is more reasonable,the selection of the migration controller and the target controller is more reasonable,the load balancing of the control plane is realized,the number of migrations and cost are reduced,and the performance of the controller is improved.…”

    Effects of osthole on renal tubular epithelial cell injury and Nrf2/HO-1 signal pathway induced by high glucose,hypoxia and reoxygenation by Han Ming-yue, Ding Yue-mei, Song Kai-yun

    Published 2022-05-01
    “…ObjectiveTo explore the effects of osthole on renal tubular epithelial cell damage and Nrf2/HO-1 signal pathway induced by high glucose,hypoxia and reoxygenation.MethodsHuman renal tubular epithelial cells HK-2 were cultured in high-glucose medium and subjected to hypoxia-reoxygenation treatment to establish a cellular model.CCK-8 experiment was utilized for detecting the effects of 0,10,20,40,80,160 µg/ml osthole on its growth and screen the optimal concentration.HK-2 cells were divided into controlmodel,osthole (80 µg/ml),ML385 (Nrf2 inhibitor,20 nmol/ml) and osthole (80 µg/ml)+ML385 (20 nmol/ml) groups.Except for control group,the other groups were induced for establishing cellular models.After high glucose,hypoxia and reoxygenation,CCK-8 experiment was utilized for detecting cellular viability in each group.Kits were employed for measuring the levels of reactive oxygen species (reactive oxygen species,ROS),glutathione peroxidase (GSH-Px),malondialdehyde (MDA),lactate dehydrogenase (LDH),tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6) and interleukin-1β (IL-1β); Immunofluorescence for detecting the expression of Nrf2/HO-1 pathway protein; Western blot for detecting the expression of Nrf2/HO-1 pathway protein.ResultsCompared with control group,HK-2 cellular viability (100±0 <italic>vs</italic> 43.47±6.14),cellular GSH-Px level (9.53±1.64 <italic>vs</italic> 3.25±0.32) and cellular Nrf2 protein (1.78±0.30 <italic>vs</italic> 0.89±0.12) were markedly down-regulated in model group (all <italic>P</italic>&lt;0.05); the levels of ROS (1.13±0.17 <italic>vs</italic> 6.52±1.03) and TNF-α spiked markedly (all <italic>P</italic>&lt;0.05).Compared with model and osthole + ML385 groups,HK-2 cellular viability (43.47±6.14,44.83±7.06 <italic>vs</italic> 87.76±9.42),cellular GSH-Px level (3.25±0.32,3.27±0.38 <italic>vs</italic> 9.07±1.78) and cellular Nrf2 protein (0.89±0.12,0.90±0.18 <italic>vs</italic> 1.74±0.26) rose in osthole group (<italic>P</italic>&lt;0.05); ROS (6.52±1.03,6.47±0.96 <italic>vs</italic> 1.59±0.21) and TNF-α declined (both <italic>P</italic>&lt;0.05); HK-2 cellular viability (43.47±6.14,44.83±7.06 <italic>vs</italic> 24.80±3.79),cellular GSH-Px level (3.25±0.32,3.27±0.38 <italic>vs</italic> 0.88±0.15) and cellular Nrf2 protein (0.89±0.12,0.90±0.18 <italic>vs</italic> 0.30±0.05) decreased in ML385 group (all <italic>P</italic>&lt;0.05); ROS (6.52±1.03,6.47±0.96 <italic>vs</italic> 9.76±2.02) and TNF-α increased (all <italic>P</italic>&lt;0.05).ConclusionOsthole can up-regulate the expression of Nrf2/HO-1 signaling pathway protein,suppress ROS and inflammatory factors production induced by high glucose,hypoxia and reoxygenation,thereby relieving oxidative stress and inflammation and lessening the damage of renal tubular epithelial cells.…”
