Review of the Research on the Optimization of the Energy Consumption of the Cloud Platform
Chun-mao Jiang,Yi-bing Li,Li Zhi-cong 보안공학연구지원센터 2016 International Journal of Smart Home Vol.10 No.8
Cloud platform is a basic platform to support large data, large-scale and high-frequency access computing. The high-energy consumption of the cloud platform and the schedule of multi-constrained combination in cloud applications is challenging issues faced by the cloud computing. We conducted a systematic review in this paper for the energy consumption of a cloud platform, and pointed out the existing problems, and put forward ideas to solve the above problems by constructing the four-level system. Firstly, by conducting virtualization management to the physical resources in the cloud to form the layer of virtual resource. Then, named as presentation layer, to build a formal model of cloud application multi_attribute with effective description, measurement, calculation. Based on this proposed scheduling application layer enables cloud applications to meet the multiple objectives with multi-attribute, heuristic, feedback, iterative scheduling and cloud resources, energy optimization. It laid the foundation for the formation of cloud platform architecture, key technologies and algorithms, which satisfy the multiple objectives: the maximum possible scheduling of the multi-attribute combination constraint application, the optimization for energy consumption and resources in cloud computing.

A meteorological model, RAMS, and a commercial computational fluid dynamics (CFD) model, FLUENT are combined as a one-way off-line nested modeling system, namely, RAMS/FLUENT system. The system is experimentally applied in the wind simulation over a complex terrain, with which numerical simulations of wind field over Foyeding weather station located in the northwest mountainous area of Beijing metropolis are performed. The results show that the method of combining a meteorological model and a CFD model as a modeling system is reasonable. In RAMS/FLUENT system, more realistic boundary conditions are provided for FLUENT rather than idealized vertical wind profiles, and the finite volume method (FVM) of FLUENT ensures the capability of the modeling system on describing complex terrain in the simulation. Thus, RAMS/FLUENT can provide fine-scale realistic wind data over complex terrains.

Chun-xiao Li,Ying Liu,Yu-zhen Zhang,Jing-chun Li,Jiang Lai 대한약학회 2022 Archives of Pharmacal Research Vol.45 No.6
The Astragalus polysaccharide is an importantbioactive component derived from the dry root of Astragalusmembranaceus . This review aims to provide a comprehensiveoverview of the research progress on the immunomodulatoryeff ect of Astragalus polysaccharide and providevaluable reference information. We review the immunomodulatoryeff ect of Astragalus polysaccharide on central andperipheral immune organs, including bone marrow, thymus,lymph nodes, spleen, and mucosal tissues. Furthermore, theimmunomodulatory eff ect of Astragalus polysaccharide on avariety of immune cells is summarized. Studies have shownthat Astragalus polysaccharide can promote the activities ofmacrophages, natural killer cells, dendritic cells, T lymphocytes,B lymphocytes and microglia and induce the expressionof a variety of cytokines and chemokines. The immunomodulatoryeff ect of Astragalus polysaccharide makesit promising for the treatment of many diseases, includingcancer, infection, type 1 diabetes, asthma, and autoimmunedisease. Among them, the anticancer effect is the mostprominent. In short, Astragalus polysaccharide is a valuableimmunomodulatory medicine, but further high-qualitystudies are warranted to corroborate its clinical effi cacy.

To understand better the mechanisms that regulate the water stress response in wheat, we conducted a comparative analysis of transcript profiles in roots from two wheat genotypes -- drought-tolerant ‘Luohan No. 2’ (LH)and drought-susceptible ‘Chinese Spring’ (CS). In LH roots,3831 transcripts displayed changes in expression of at least two-fold over the well-watered control when drought treatment was applied. Of these, 1593 were induced while 2238 were repressed. Relatively fewer transcripts were drought-responsive in CS; i.e., 1404 transcripts were induced and 1493 were repressed. In common between LH and CS,569 transcripts were induced and 424 transcripts were repressed. In all, 689 transcripts (757 probe sets) identified from LH and 537 transcripts (575 probe sets) from CS were annotated and classified into 10 functional categories. Among those annotated transcripts from LH and CS that had fold-change ratios of at least 4, 92 induced transcripts were common to both, while 23 transcripts were specifically induced in LH. Gene ontology analysis of these induced genes showed highly significant enrichment for multiple terms related to abiotic stimuli, organic acid biosynthesis,and lipid metabolism. This suggests that these gene groups play important roles during the stress response in LH and CS, and might also be responsible for differences in drought tolerance between those genotypes.

In this study, the full-length GIH cDNA sequence from Litopenaeus vannamei was cloned from the eyestalk by reverse transcriptase polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends. The fulllength GIH cDNA was 865 bp with a 288 bp open-reading frame, which encoded a 96 amino acid prepro-GIH with 17 amino acid signal peptide. L. vannamei GIH (LvGIH) can be classified as a member of type-II crustacean hyperglycemic hormone polypeptide family. LvGIH shares 93.8 and 66.7 % amino acid sequence identity with GIH from Penaeus monodon, and the molt-inhibiting hormone from Marsupenaeus japonicas, respectively. By quantitative real-time PCR (qPCR), LvGIH mRNA transcripts were detected in fertilized eggs, nauplius, zoea, mysis and juveniles of 25, 35 and 40 days old. LvGIH transcript levels increased significantly with the development from fertilized eggs to juveniles. LvGIH transcript levels were highest in juveniles at 35 days old. By RT-PCR, LvGIH mRNA transcripts were detected only in the eyestalks and brains but not in the muscles, intestines, gills, heart, hepatopancreas, ovaries and testes of adults, and there was no difference in the expression level of LvGIH between males and females. Using the P. monodon anti-GIH antibody, we showed that LvGIH was located mainly in the XO-SG and slightly in axon, with similar fluorescence intensity found in XO and SG. To summarize, we have cloned and characterized the GIH of the shrimp L. vannamei. In addition to the GIH properties described in other crustaceans, a peak of LvGIH expression was identified at the time of sexual differentiation (i.e., day 35 larvae) suggesting that LvGIH may also be involved in the control of this process.

The Physiological Occlusion of the Central Canal May Be a Prerequisite for Syringomyelia Formation
Chuan Jiang,Xinyu Wang,Chunli Lu,Qian Li,Longbing Ma,Wei Li,Shengyu Cui,Kang Li,Xiang Wang,Yuxin Feng,Fengzeng Jian 대한척추신경외과학회 2023 Neurospine Vol.20 No.4
Objective: Syringomyelia is a common central nervous system disease characterized by the dilation of the central canal (CC). Regarding the pathogenesis of syringomyelia, cerebrospinal fluid (CSF) circulation obstruction in the subarachnoid space (SAS) of the spinal cord has been widely accepted. However, clinical and animal studies on obstructing the CSF in SAS failed to form syringomyelia, challenging the theory of SAS obstruction. The precise pathogenesis remains unknown. Methods: We utilized an extradural compression rat model to investigate the pathogenesis underlying syringomyelia. Magnetic resonance imaging enabled detection of syringomyelia formation. To assess CSF flow within the SAS, Evans blue was infused into the cisterna magna. Histological analysis allowed morphological examination of the CC. Furthermore, CSF flow through the CC was traced using Ovalbumin Alexa-Flour 647 conjugate (OAF-647). Scanning electron microscopy (SEM) enabled visualization of ependymal cilia. Results: The findings showed that the dura mater below the compression segment exhibited lighter coloration relative to the region above the compression, indicative of partial obstruction within the SAS. However, the degree of SAS occlusion did not significantly differ between syringomyelia (SM-Y group) and those without (SM-N group). Intriguingly, hematoxylin and eosin staining and CSF tracing revealed occlusion of the CC accompanied by reduced CSF flow in the SM-Y group compared to SM-N and control groups. SEM images uncovered impairment of ependymal cilia inside the syringomyelia. Conclusion: CC occlusion may represent a physiological prerequisite for syringomyelia formation, while SAS obstruction serves to initiate disease onset. The impairment of ependymal cilia appears to facilitate progression of syringomyelia.

Background: A number of studies have identified a shared susceptibility locus in phospholipase C epsilon 1 (PLCE1) for esophageal squamous cell carcinoma (ESCC) and gastric cardia adenocarcinomas (GCA). However, the results of PLCE1 expression in esophageal and gastric cancer remain inconsistent and controversial. Moreover, the effects on clinicopathological features remain undetermined. This study aimed to provide a precise quantification of the association between PLCE1 expression and the risk of ESCC and GCA through meta-analysis. Materials and Methods: Eligible studies were identified from PubMed, Wanfang Data, ISI Web of Science, and the Chinese National Knowledge Infrastructure databases. Using RevMan5.2 software, pooled odds ratios (ORs) with 95% confidence intervals (CIs) were employed to assess the association of PLCE1 expression with clinicopathological features relative to ESCC or GCA. Results: Seven articles were identified, including 761 esophageal and gastric cancer cases and 457 controls. Overall, we determined that PLCE1 expression was associated with tumor progression in both esophageal cancers (pooled OR=5.93; 95%CI=3.86 to 9.11) and gastric cancers (pooled OR=9.73; 95%CI=6.46 to 14.7). Moreover, invasion depth (pooled OR=3.62; 95%CI=2.30 to 5.70) and lymph node metastasis (pooled OR=4.21; 95%CI=2.69 to 6.59) were linked with PLCE1 expression in gastric cancer. However, no significant associations were determined between PLCE1 overexpression and the histologic grade, invasion depth, and lymph node metastasis in esophageal cancer. Conclusions: Our metaanalysis results indicated that upregulated PLCE1 is significantly associated with an increased risk of tumor progression in ESCC and GCA. Therefore, PLCE1 expression can be appropriately regarded as a promising biomarker for ESCC and GCA patients.
