Objective To study the role of reduced form of nicotinamide adenine dinucleotide phosphate(NADPH) oxidase 4 (NOX4) in pituitary adenoma hemorrhagic stroke(pituitary apoplexy,PA). Methods Specimens were collected from the remaining specimens of pituitary adenoma surgery in the Department of Neurosurgery, Zhongshan Hospital Affiliated to Xiamen University. According to postoperative pathology, the specimens were divided into hemorrhagic stroke(PA) group and non-stroke(non-PA) group, and 18 cases were selected from each group. Hematoxylin eosin (HE) staining was used to determine whether hemorrhage. The percentage of NOX4 positive cells was detected by immunohistochemical staining. The expression of NOX4 protein was detected by Western blot. DCFH-DA probe was used to detect the fluorescence intensity of reactive oxygen species (ROS). Apoptosis rate was detected by TUNEL. Results There was a large number of erythrocytes exuded between tissues in the hemorrhagic stroke group, but no red blood cell was found in the non-stroke group. The percentage of NOX4 positive cells in hemorrhagic stroke group (21.53%±4.25%) was significantly higher than that in non-stroke group (4.29%±1.71%) (P<0.001). The expression level of NOX4 in the hemorrhagic stroke group was significantly higher than that in the non-stroke group (P<0.001).The mean fluorescence intensity of ROS in hemorrhagic stroke group was significantly higher than that in non-stroke group(P<0.001). The percentage of apoptotic cells in hemorrhagic stroke group (38.64%±12.46%) was significantly higher than that in non-stroke group (6.19%±2.40%) (P<0.001). Conclusions NOX4 is involved in the occurrence of pituitary adenoma hemorrhagic stroke. NOX4-mediated oxidative stress regulation of apoptosis is found to be potential mechanism of hemorrhagic stroke in pituitary adenomas. [ABSTRACT FROM AUTHOR]

As there have been no effective and reliable transaction mechanisms to standardize user credibility during distributed electricity transaction, an electricity transaction matching mechanism based on blockchain and mixed continuous double auction were proposed. Credit value was introduced by the mixed continuous double auction into adjustment to prices offered by users. The continuous double auction transaction matching was done through credit value and the weighted mean of offered prices. This type of matching mechanism works effectively in minimizing the effects of malicious node on electricity resource allocation and improving total revenues as well as the transaction enthusiasm of users. To maximize the total revenues, the pricing strategies based on equilibrium value were proposed, and the transactions between user electricity digital certificate and fees were realized trough blockchain. Finally, the transaction mechanisms were verified to be workable through distributed electricity transaction simulation experiments. [ABSTRACT FROM AUTHOR]

A Meta study was conducted to quantitative analysis on alleviating effects and influencing factors of summer maize drought by fertilization and irrigation, and to provide a theoretical basis for dealing with summer maize drought disaster. A total of 56 literatures on summer maize drought experiment were obtained through literature search, including 26 literatures on fertilization and 30 literatures on irrigation. Taking no measures as the control, Meta-analysis was conducted to investigate the alleviating effects and its influencing factors of fertilization and irrigation on summer maize drought. The results showed that: under drought stress, fertilization and irrigation significantly increased summer maize yield by 19.30% and 25.19%, respectively, compared with no measures. Different types of fertilizer had different alleviating effects on drought. Applying constant fertilizer and trace fertilizer could increase summer maize yield by 20.55% and 10.10%, respectively. Nitrogen fertilizer is the most commonly used of the constant fertilizers, among them, the application of controlled urea had the best effect, which could increase summer maize yield by 31.63% under the condition of drought, followed by the application of conventional urea in batches, with the yield increase rate of 20.73%, and the yield increase rate of conventional urea by all base application was the lowest, which was only 11.69%. In the range of 315kg·ha−1 N application amount, the yield increase rate of summer maize was positively correlated with the N application amount. Soil bulk density and organic matter content also have an impact on the fertilization effect under drought conditions, and the fertilization effect was better on soils with low bulk density and high organic matter content. When planting density was higher, the alleviating effect of fertilization on summer maize drought decreased, but was not significant. When drought stress occurred in different growth stages of summer maize, the alleviating effect of irrigation was different. When drought continued in the whole growth period, the alleviating effect of irrigation was the best, and the yield increase rate reached 42.98%. The effect of irrigation on alleviating drought in tasseling-grouting stage was better than that in other growth stages. Soil bulk density and organic matter content had significant influence on irrigation effect, the lower soil bulk density and the higher organic matter content, the better alleviating effect of irrigation on summer maize drought. The planting density also had an effect on the irrigation effect, and the alleviating effect of dense planting decreased. For different summer maize varieties, the alleviating effect of irrigation on drought-sensitive cultivars was significantly better than drought-tolerant cultivars. In conclusion, both fertilization and irrigation could significantly alleviate drought of summer maize. The effect of fertilization was greatly affected by fertilizer type and the method of application, and the application effect of controlled fertilizer was better. Irrigation is the most direct and effective way to alleviate drought during the critical water-demanding period of summer maize. The effects of the two drought mitigation measures for summer maize were affected by soil properties and planting density, and the alleviating effect of irrigation was better than fertilization under different soil bulk density and planting density, and these factors should be considered in the specific implementation.

With the increase of network transmission bandwidth, complex infrastructure operations in data centers oc-cupy more and more computing resources, affecting service processing performance. Data Processor Unit (DPU) is a newly developed special purpose processor. The background is to deal with the performance bottleneck caused by the exponential growth of data volume and complexity in data center. The emergence of DPU is a phased symbol of heterogeneous computing. The core problem to be solved is to reduce the total cost of ownership of the entire system and improve the efficiency of the entire computing system based on the infrastructure. That is, the load that is "inefficient in CPU processing and unable to be handled by GPU" is offloaded to DPU. Firstly, the development background of DPU is introduced, and the hardware architecture of DPU is analyzed based on network processing model. Besides, DPU is compared with smart network interface card and network processor. After that, DPU programming model, DPU products and applications in the industry are introduced. Finally, the future research directions of DPU are summarized and prospected. [ABSTRACT FROM AUTHOR]
