Li-hua Wu,Xu-zhang Zhang,Xiao-lei Pan,Meng-yuan Wu 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.2

Aiming at the problem of limited logical resources of FPGA and low rates of internal resource utilization, the design of the static reconfiguration system was introduced in this paper. Based on the structure of CPLD matching FPGA, the static reconfiguration system is able to enhance the scalability of the FPGA device. Major functionality in the static reconfiguration system is accomplishing field reconfiguration of the FPGA device without PC. Users are able to flexibly change the different configuration files in FPGA for that the internal resources of FPGA are occupied by the configuration files of different function at different times. The experimental results showed that the system achieved dynamic switching between different logic function and time division multiplexing of internal resources. The generality of FPGA and the rates of internal resource utilization were improved and the power dissipation was reduced by this design.

The global commercial cultivation of transgenic crops, including glyphosate-tolerant soybean, has increased widely in recent decades with potential impact on the environment. The bulk of previous studies showed different results on the effects of the release of transgenic plants on the soil microbial community, especially rhizosphere bacteria. In this study, comparative analyses of the bacterial communities in the rhizosphere soils and surrounding soils were performed between the glyphosate-tolerant soybean line NZL06-698 (or simply N698), containing a glyphosate-insensitive EPSPS gene, and its control cultivar Mengdou12 (or simply MD12), by a 16S ribosomal RNA gene (16S rDNA) amplicon sequencing-based Illumina MiSeq platform. No statistically significant difference was found in the overall alpha diversity of the rhizosphere bacterial communities, although the species richness and evenness of the bacteria increased in the rhizosphere of N698 compared with that of MD12. Some influence on phylogenetic diversity of the rhizosphere bacterial communities was found between N698 and MD12 by beta diversity analysis based on weighted UniFrac distance. Furthermore, the relative abundances of part rhizosphere bacterial phyla and genera, which included some nitrogen-fixing bacteria, were significantly different between N698 and MD12. Our present results indicate some impact of the glyphosate-tolerant soybean line N698 on the phylogenetic diversity of rhizosphere bacterial communities together with a significant difference in the relative abundances of part rhizosphere bacteria at different classification levels as compared with its control cultivar MD12, when a comparative analysis of surrounding soils between N698 and MD12 was used as a systematic contrast study.

Zhao, Meng-Meng,Zhang, Yue,Shen, Li,Ren, Yang-Wu,Li, Xue-Lian,Yin, Zhi-Hua,Zhou, Bao-Sen Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.6

Background: This study was conducted to investigate the association between single nucleotide polymorphisms (SNPs) in telomerase reverse transcriptase (TERT) and cleft lip and palate transmembrane1-like (CLPTM1L) and lung cancer risk in a Chinese population. Methods: We performed a hospital-based case-control study, including 980 lung cancer cases and 1000 cancer-free controls matched for age and sex. Each case and control was interviewed to collect information by well-trained interviewers. A total of 5 ml of venous blood was collected for genotype testing of TERT rs2736098 and CLPTM1L rs401681 using TaqMan methodology. Results: The results revealed that the variant homozygote TERT rs2736098TT was associated with an increased risk of lung cancer (OR=2.017, 95%CI=1.518-2.681), especially lung adenocarcinoma (OR=2.117, 95%CI=1.557-3.043) and small cell carcinoma (OR=1.979, 95%CI: 1.174-3.334), compared with the TERT rs2736098CC genotype. Similar results were observed in non-smokers. Conclusion: The TERT rs2736098 polymorphism might affect the susceptibility to lung cancer in Chinese populations. The associations need to be verified in larger and different populations.

Effect of Trichostatin A on CNE2 Nasopharyngeal Carcinoma Cells - Genome-wide DNA Methylation Alteration

Yang, Xiao-Li,Zhang, Cheng-Dong,Wu, Hua-Yu,Wu, Yong-Hu,Zhang, Yue-Ning,Qin, Meng-Bin,Wu, Hua,Liu, Xiao-Chun,Lina, Xing,Lu, Shao-Ming Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.11

Trichostatin A (TSA) is a histone deacetylase (HDAC) inhibitor. We here investigated its effects on proliferation and apoptosis of the CNE2 carcinoma cell line, and attempted to establish genome-wide DNA methylation alteration due to differentially histone acetylation status. After cells were treated by TSA, the inhibitory rate of cell proliferation was examined with a CCK8 kit, and cell apoptosis was determined by flow cytometry. Compared to control, TSA inhibited CNE2 cell growth and induced apoptosis. Furthermore, TSA was found to induce genome-wide methylation alteration as assessed by genome-wide methylation array. Overall DNA methylation level of cells treated with TSA was higher than in controls. Function and pathway analysis revealed that many genes with methylation alteration were involved in key biological roles, such as apoptosis and cell proliferation. Three genes (DAP3, HSPB1 and CLDN) were independently confirmed by quantitative real-time PCR. Finally, we conclude that TSA inhibits CNE2 cell growth and induces apoptosis in vitro involving genome-wide DNA methylation alteration, so that it has promising application prospects in treatment of NPC in vivo. Although many unreported hypermethylated/hypomethylated genes should be further analyzed and validated, the pointers to new biomarkers and therapeutic strategies in the treatment of NPC should be stressed.

Effect of Shadow Banking Activities on Firm Risk and Performance: Entrusted Loan Evidence from Chinese Listed Firms

Meng-Wen Wu,Xiaoyan Wang,Sijia Qiao,Chung-Hua Shen,Juan Wang 한국증권학회 2022 Asia-Pacific Journal of Financial Studies Vol.51 No.2

This study investigates the effect of non-financial firms’ activities in shadow banking on firm risk and performance. Using manually collected data of entrusted loans from Chinese listed firms, we find that lending firms’ bankruptcy risk and performance increases from their engagement of entrusted loan businesses in the year the loans are issued and in the following year. Further, firms’ risk increases and performance improves significantly when firms are financially healthy, financially constrained, and non-state-owned. Overall, our findings provide policy implications that the risk of shadow banking activities must be cautious.

Meta-analysis of Associations between ATM Asp1853Asn and TP53 Arg72Pro Polymorphisms and Adverse Effects of Cancer Radiotherapy

Su, Meng,Yin, Zhi-Hua,Wu, Wei,Li, Xue-Lian,Zhou, Bao-Sen Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.24

Background: The ataxia telangiectasia mutated (ATM) protein and p53 play key roles in sensing and repairing radiation-induced DNA double strand breaks (DSBs). Accumulating epidemiological evidence indicates that functional genetic variants in ATM and TP53 genes may have an impact on the risk of radiotherapy-induced side effects. Here we performed a meta-analysis to investigate the potential interaction between ATM Asp1853Asn and TP53 polymorphisms and risk of radiotherapy-induced adverse effects quantitatively. Materials and Methods: Relevant articles were retrieved from PubMed, ISI Web of Science and the China National Knowledge Infrastructure (CNKI) databases. Eligible studies were selected according to specific inclusion and exclusion criteria. Odds ratios (ORs) and 95% confidence intervals (CIs) were pooled to estimate the association between ATM Asp1853Asn and TP53 Arg72Pro polymorphisms and risk of radiotherapy adverse effects. All analyses were performed using the Stata software. Results: A total of twenty articles were included in the present analysis. In the overall analysis, no significant associations between ATM Asp1853Asn and TP53 Arg72Pro polymorphisms and the risk of radiotherapy adverse effects were found. We conducted subgroup analysis stratified by type of cancer, region and time of appearance of side effects subsequently. No significant association between ATM Asp1853Asn and risk of radiotherapy adverse effects was found in any subgroup analysis. For TP53 Arg72Pro, variant C allele was associated with decreased radiotherapy adverse effects risk among Asian cancer patients in the stratified analysis by region (OR=0.71, 95%CI: 0.54-0.93, p=0.012). No significant results were found in the subgroup analysis of tumor type and time of appearance of side effects. Conclusions: The TP53 Arg72Pro C allele might be a protective factor of radiotherapy-induced adverse effects among cancer patients from Asia. Further studies that take into consideration treatment-related factors and patient lifestyle including environmental exposures are warranted.

TP63 Gene Polymorphisms, Cooking Oil Fume Exposure and Risk of Lung Adenocarcinoma in Chinese Non-smoking Females

Yin, Zhi-Hua,Cui, Zhi-Gang,Ren, Yang-Wu,Su, Meng,Ma, Rui,He, Qin-Cheng,Zhou, Bao-Sen Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.11

Background: Genetic polymorphisms of TP63 have been suggested to influence susceptibility to lung adenocarcinoma development in East Asian populations. This study aimed to investigate the relationship between common polymorphisms in the TP63 gene and the risk of lung adenocarcinoma, as well as interactions of the polymorphisms with environmental risk factors in Chinese non-smoking females. Methods: A case-control study of 260 cases and 318 controls was conducted. Data concerning demographic and risk factors were obtained for each subject. The genetic polymorphisms were determined by Taqman real-time PCR and statistical analyses were performed using SPSS software. Results: For 10937405, carriers of the CT genotype or at least one T allele (CT/TT) had lower risks of lung adenocarcinoma compared with the homozygous wild CC genotype in Chinese nonsmoking females (adjusted ORs were 0.68 and 0.69, 95%CIs were 0.48-0.97 and 0.50-0.97, P values were 0.033 and 0.030, respectively). Allele comparison showed that the T allele of rs10937405 was associated with a decreased risk of lung adenocarcinoma with an OR of 0.78 (95%CI=0.60-1.01, P=0.059). Our results showed that exposure to cooking oil fumes was associated with increased risk of lung adenocarcinoma in Chinese nonsmoking females (adjusted OR=1.58, 95%CI=1.11-2.25, P=0.011). However, we did not observe a significant interaction of cooking oil fumes and TP63 polymorphisms. Conclusion: TP63 polymorphism might be a genetic susceptibility factor for lung adenocarcinoma in Chinese non-smoking females, but no significant interaction was found with cooking oil fume exposure.

Su-Qian Wu,Shang-Long Gao,Hong-Hong Liu,Xin-Yi Sun,Long Hao,Le Jia,Li-Fei Pang,Shou-Hua Jia,Meng-Shi Jia 한국고분자학회 2013 Macromolecular Research Vol.21 No.6

The extraction parameters of intracellular polysaccharide (IPS) from Pleurotus citrinopileatus SM-01mycelia were optimized, and the in vitro and in vivo antioxidant activities of IPS were investigated. The optimum conditions of IPS extraction were predicted to be an ultrasonic treatment time of 664.09 s, precipitation time of 23.03h and pH 7.36, and IPS yield was estimated at 16.13%. The in vitro inhibition effects of IPS at a dosage of 5 g/L on the superoxide anion, 1,1-diphenyl-2-picrylhydrazyl (DPPH) and hydroxyl radicals were 73.96±4.62%, 69.2±4.37%,and 50.75±4.39%, respectively, which were 72.56±5.08%, 22.83±1.94%, and 43.93±3.26% higher than that of butylated hydroxytoluene (BHT), respectively. The reducing power of IPS was 0.9±0.07, 69.81±5.24% higher than that of BHT. The activities of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), catalase (CAT) and alanine aminotransferase (ALT) in mice blood were 241.38±23.19, 454.95±42.39, 60.32±5.16, and 32.39±2.54 U/mL,respectively, and the malonaldehyde (MDA) level was 9.54±0.72 nmol/mL. The results provided a reference for the large-scale extraction of IPS by P. citrinopileatus SM-01 in industrial fermentation, suggesting that the IPS can be used as a potential antioxidant, which enhances adaptive immune responses.

Liu Nai-Hua,Liu Hong-Qian,Zheng Jia-Yi,Zhu Meng-Lu,Wu Li-Hao,Pan Hua-Feng,He Xing-Xiang 한국미생물학회 2023 The journal of microbiology Vol.61 No.8

Accumulating studies have raised concerns about gut dysbiosis associating autism spectrum disorder (ASD) and its related symptoms. However, the effect of gut microbiota modification on the Chinese ASD population and its underlying mechanism were still elusive. Herein, we enrolled 24 ASD children to perform the first course of fresh washed microbiota transplantation (WMT), 18 patients decided to participate the second course, 13 of which stayed to participate the third course, and there were 8 patients at the fourth course. Then we evaluated the effects of fresh WMT on these patients and their related symptoms. Our results found that the sleeping disorder symptom was positively interrelated to ASD, fresh WMT significantly alleviated ASD and its sleeping disorder and constipation symptoms. In addition, WMT stably and continuously downregulated Bacteroides/ Flavonifractor/Parasutterella while upregulated Prevotella_9 to decrease toxic metabolic production and improve detoxification by regulating glycolysis/myo-inositol/D-glucuronide/D-glucarate degradation, L-1,2-propanediol degradation, fatty acid β-oxidation. Thus, our results suggested that fresh WMT moderated gut microbiome to improve the behavioral and sleeping disorder symptoms of ASD via decrease toxic metabolic production and improve detoxification. Which thus provides a promising gut ecological strategy for ASD children and its related symptoms treatments.
