Gang Yuan,Rui-zhi Sun,Yong Xiang,Yin-xue Shi 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.2

In order to achieve the interconnection between different workflow management systems, it was proposed that all the distributed workflow systems would be encapsulated as web services to perform the entire business process collaboratively by the way of processes’ composition in this paper. By analyzing the comparison between the composition of processes and ordinary Web service, we studied interactive control, the parameters required to be passed through the distributed workflow systems, the workflow system service’s interfaces and its packaging. Furthermore we put forward a general method of the workflow systems interactive interfaces’ extension and the way of the workflow service’s encapsulating and invoking. By this approach, it can easily combine the processes or process fragments which deployed on different workflow systems without other agents and components. It also provides support for the interconnection of the workflow systems in distributed environment, and ultimately achieves a coordinated operation between different workflow engines.

Yuan Gang,Sun Rui-zhi,Shi Yin-xue 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.6

In order to achieve the collaborative completion of entire business process by composition between different workflow management systems, a process composition method based on dynamic programming has been put forward. By analyzing differences and relations between process composition and Web services composition, many aspects have been analyzed with regard to service interface of the workflow system, the interaction control between the workflow systems, parameters and message’s delivery and the planning indexes according to the characteristics of process interaction among the distributed workflow systems. When the process is running, according to the indicators and expectations of users, the optimal workflow services and sub-processes would be selected through dynamic planning method, to provide support to the dynamic combination of workflow processes in a distributed environment.

Chao Yuan,Gang Xue,Mei-Zhi Yang,Lu-Ping Luo,Kyoo-Sik Shin,Xue-Wei Zhang 제어로봇시스템학회 2015 제어로봇시스템학회 국제학술대회 논문집 Vol.2015 No.10

In controlling the robot interacting with the external environment, an important role is played by the force/moment sensors. To design a good force sensor, we need to make a good model first. This paper presents a systematic modeling method of one type of force/moment sensor. A model of a previously designed sensor has been built on the basis of static and kinematic equations and a block form of the strain compliance matrix is obtained using the model.

Han, Ye,Xue, Xiao-Feng,Shen, Hu-Gang,Guo, Xiao-Bo,Wang, Xu,Yuan, Bin,Guo, Xing-Po,Kuang, Yu-Ting,Zhi, Qiao-Ming,Zhao, Hong Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.11

Objective: Beclin-1 has recently been observed as an essential marker of autophagy in several cancers. However, the prognostic role of Beclin-1 in colorectal neoplasia remains controversial. Our study aimed to evaluate the potential association between Beclin-1 expression and the outcome of colorectal cancer patients. Materials and Methods: All related studies were systematically searched in Pubmed, Embase, Springer and Chinese National Knowledge Infrastructure databases (CNKI), and then a meta-analysis was performed to determine the association of Beclin-1 expression with clinical outcomes. Finally, a total of 6 articles were included in our analysis. Results: Our data showed that high Beclin-1 expression in patients with CRC was associated with poor prognosis in terms of tumor distant metastasis (OR=2.090, 95%CI=1.061-4.119, p=0.033) and overall survival (RR=1.422, 95%CI=1.032-1.959, p=0.031). However, we did not found any correlation between Beclin-1 over-expression and tumor differentiation (OR=1.711, 95%CI=0.920-3.183, p=0.090). In addition, there was no evidence of publication bias as suggested by Egger's tests for tumor distant metastasis (p=1.000), differentiation (p=1.000) and OS (p=0.308). Conclusions: Our present meta-analysis indicated that elevated Beclin-1 expression iss associated with tumor metastasis and a poor prognosis in patients with CRC. Beclin-1 might serve as an efficient prognostic indicator in CRC, and could be a new molecular target in CRC therapy.

Background: To systematically summarize the association between the X-ray repair cross complementing 3 (XRCC3) gene polymorphism and oral cancer susceptibility by meta-analysis. Materials and Methods: Databases including PubMed, EMbase, CNKI, VIP and WanFang Data were searched to identify case-control studies concerning the association between an XRCC3 gene polymorphism and the risk of oral cancer from the inception to June 2014. Two reviewers independently screened the literature according to the criteria, extracted the data and assessed the quality. Then meta-analysis was performed using Stata 11.0 software. Results: Seven published case-control studies including 775 patients with oral cancer and 1922 controls were selected. Associations between the rs861539 polymorphism and overall oral cancer risk were not statistically significant in all kinds of comparison models (CT vs CC: OR=0.94, 95%CI=0.74-1.18; TT vs CC: OR=0.94, 95%CI=0.64-1.38; dominant model: OR=0.95, 95%CI=0.76-1.18; recessive model: OR=0.94, 95%CI=0.69-1.29; allele T vs C: OR=0.97, 95%CI=0.84-1.11). In the stratified analysis by ethnicity, no significant associations were found among Asians and Caucasians. On stratification by tumor type, no significant associations were found for cancer and oral premalignant lesions. Conclusions: The XRCC3 gene polymorphism was not found to be associated with the risk of oral cancer. Considering the limited quality of the included case-control studies, more high quality studies with large sample size are needed to verify the above conclusion.

Baicalin, a flavonoid, has a wide range ofpharmacological properties, including immunomodulation. The objective of this study was to investigate the effect ofbaicalin on the balance of T helper 17 (Th17) and regulatoryT (Treg) cells in a colitis model. The rat colitis modelwas induced by 2,4,6-trinitrobenzene sulfonic acid(TNBS). Baicalin (10 ml/kg, each) or mesalazine (positivecontrol) was then administered orally for 7 days. Inflammatoryand immunological responses were evaluated bypathology, enzyme-linked immunosorbent assay, real-timepolymerase chain reaction, western blot analysis, and flowcytometry. Our study showed that baicalin not only significantlyattenuated TNBS-induced colitis by reducing thedisease activity index as well as macroscopic and microscopicscores, but it also improved the weight loss andshortening of the colon. Baicalin treatment also induced asignificant decrease in the levels of inflammatory mediators,including the myeloperoxidase activity, the levels oftumor necrosis factor a, IL-1b, and Th1-related cytokinesIL-12 and IFN-c. Furthermore, the beneficial effects ofbaicalin seem to be associated with regulation of the Th17and Treg paradigm. We found that administration ofbaicalin significantly downregulated the number of Th17cells and the levels of Th17-related cytokines (IL-17 andIL-6) and retinoic acid receptor-related orphan receptor ct. In contrast, there was an increase in Treg cells numbers,Treg-related cytokines transforming growth factor-b andIL-10, and forkhead box P3. Our results suggest that theanti-inflammatory effect of baicalin may be linked tomodulation of the balance between Th17 and Treg cells inTNBS-induced ulcerative colitis.

ATM Signaling Pathway Is Implicated in the SMYD3-mediated Proliferation and Migration of Gastric Cancer Cells

Wang, Lei,Wang, Qiu-Tong,Liu, Yu-Peng,Dong, Qing-Qing,Hu, Hai-Jie,Miao, Zhi,Li, Shuang,Liu, Yong,Zhou, Hao,Zhang, Tong-Cun,Ma, Wen-Jian,Luo, Xue-Gang The Korean Gastric Cancer Association 2017 Journal of gastric cancer Vol.17 No.4

Purpose: We previously found that the histone methyltransferase suppressor of variegation, enhancer of zeste, trithorax and myeloid-nervy-deformed epidermal autoregulatory factor-1 domain-containing protein 3 (SMYD3) is a potential independent predictive factor or prognostic factor for overall survival in gastric cancer patients, but its roles seem to differ from those in other cancers. Therefore, in this study, the detailed functions of SMYD3 in cell proliferation and migration in gastric cancer were examined. Materials and Methods: SMYD3 was overexpressed or suppressed by transfection with an expression plasmid or siRNA, and a wound healing migration assay and Transwell assay were performed to detect the migration and invasion ability of gastric cancer cells. Additionally, an MTT assay and clonogenic assay were performed to evaluate cell proliferation, and a cell cycle analysis was performed by propidium iodide staining. Furthermore, the expression of genes implicated in the ataxia telangiectasia mutated (ATM) pathway and proteins involved in cell cycle regulation were detected by polymerase chain reaction and western blot analyses. Results: Compared with control cells, gastric cancer cells transfected with si-SMYD3 showed lower migration and invasion abilities (P<0.05), and the absence of SMYD3 halted cells in G2/M phase and activated the ATM pathway. Furthermore, the opposite patterns were observed when SMYD3 was elevated in normal gastric cells. Conclusions: To the best of our knowledge, this study provides the first evidence that the absence of SMYD3 could inhibit the migration, invasion, and proliferation of gastric cancer cells and halt cells in G2/M phase via the ATM-CHK2/p53-Cdc25C pathway. These findings indicated that SMYD3 plays crucial roles in the proliferation, migration, and invasion of gastric cancer cells and may be a useful therapeutic target in human gastric carcinomas.
