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.

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.

Background: Both alcohol and aqueous extracts of Sauromatum giganteum(Engl.) Cusimano and Hett, the dried root tuber of which is named Baifuzi in Chinese, have been used for folklore treatment of cancer in Northeast of China. However, little is known about which is most suitable to the cancer therapy. Materials and Methods: Serum pharmacology and MTT assays were adopted to detect the effects of ethanol and aqueous extracts of Sauromatum giganteum(Engl.) Cusimano and Hett, prepared by heat reflux methods, on proliferation of different cancer cells. Results: Cancer cells treated with medium supplemented with 10%, 20%, 40% serum(v/v) containing ethanol extract had a decline in viability, with inhibition rates of 7.69%, 21.8%, 41.9% in MCF-7 cells, 42.8%, 48.1%, 51.8% in SGC-7901 cells, 44.1%, 49.2%, 53.7% in SMMC-7721 cells, 6.8%, 15.2%, 39.8% in HepG2 cells, 7.57%, 16.3%, 36.2% in HeLa cells, 6.24%, 12.5%, 27.4% in A549 cells, and 7.20%, 17.5%, 31.3% in MDA-MB-231 cells, respectively. Viability in the aqueous extract groups was no different with that of controls. Conclusions: An ethanol extract of Sauromatum giganteum(Engl.) Cusimano and Hett inhibited the proliferation of SMMC-7721, SGC-7901 and MCF-7 cells, which supports the use of alcoholic but not aqueous extracts for control of sensive cancers, which might include hepatocarcinoma, gastric cancer and breast cancer.

Sepsis is a clinical syndrome with no effective protective or therapeutic treatments. Acacetin, a natural flavonoid compound, has anti-oxidative and anti-inflammatory effects which can potentially work to reduce sepsis. We investigated the potential protective effect of acacetin on sepsis-induced acute lung injury (ALI) ALI and dissect out the underlying mechanisms. Mice were divided into five groups: a sham group, a sepsis-induced ALI group, and three sepsis groups pre-treated with 20, 40, and 80 mg/kg body weight of acacetin. We found that acacetin significantly attenuated sepsis-induced ALI, in histological examinations and lung edema. Additionally, acacetin treatment decreased protein and inflammatory cytokine concentration and the number of infiltrated inflammatory cells in BALF compared with that in the non-treated sepsis mice. Pulmonary myeloperoxidase (MPO) activity was lower in the acacetin-pre-treated sepsis groups than in the sepsis group. The mechanism underlying the protective effect of acacetin on sepsis is related to the regulation of certain antioxidation genes, including inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), superoxide dismutases (SODs), and heme oxygenase 1 (HO-1).Taken together, our results indicate that acacetin pre-treatment inhibits sepsis-induced ALI through its anti-inflammatory and antioxidative activity, suggesting that acacetin may be a potential protective agent for sepsis-induced ALI.

Cui, Bin,Sun, Yuming,Sun, Yuqin,Shi, Yuefeng,Pei, Gang,Kong, Xiangyin,Hu, Landian 한국유전학회 2004 Genes & Genomics Vol.26 No.1
Renpenning sysndrome is an X-linked mental retardation associated with short stature, moderate microcephaly, unremakdable facies, and no other neurological abnormality. Renpenning first reported this disorder in a Mennonite family, and using this family, Renpenning Syndrome (RENS) has been mapped to Xp11.2-p11.4 Xu Cs found a Chinses family with an X-linked hereditary disease, and the clinical phenotype is similar to RENS. Recently, we performed the linkage analysis, and the result has shown ht egenetic heterogeneity of Renpenning Syndrome: a suggestive novel locus mapped to Xq21-Xqter in this Chinese family.

<P><I>Platycodon grandiflorum</I> (PG) (Korean name, <I>Doraji</I>; Chinese name, <I>Jiegeng</I>; and Japanese name, <I>Kikyo</I>) is a perennial plant in the Campanulaceae family that contains triterpenoid saponins, carbohydrates, and fibers. This study was carried out to investigate effects of root of PG on fatty liver inhibition in high fat diet (HFD)-fed C57BL/6 mice. C57BL/6 mice were divided into control, total extract of PG (T-PG, 500 mg/kg) and saponin fraction (S-PG, 50 mg/kg)-treated groups. Significant decreases in body weight, associated with fat mass reduction, were observed in PG-treated groups (<I>p</I><0.05). Hepatic lipid content and score index calculated from morphometric observations on fatty liver were significantly decreased in the PG-treated groups (<I>p</I><0.05). Moreover, activities of fatty acid synthase (FAS) and carnitine palmitoyl-transferase (CPT) were significantly suppressed and increased as compared with the control group, respectively (<I>p</I><0.05). mRNA expressions of the sterol regulatory element binding protein (SREBP1c) and stearoyl-CoA desaturase (SCD1) gene were suppressed in the T-PG and S-PG groups (<I>p</I><0.05). From these findings, we speculate that fatty liver inhibition effects of PG extract and its saponins appear to be conferred by hepatic lipogenesis and acceleration of energy expenditure, along with modulation of liver FAS and CPT activities in HFD-fed C57BL/6 mice.</P>

Li, Rong,Ju, Ming-Yang,Chen, Bin,Sun, Qing-Yuan,Chen, Guo-Liang,Shi, Mei,Wang, Xiao-Gang,Zheng, Jian-Bin Korean Chemical Society 2011 Bulletin of the Korean Chemical Society Vol.32 No.2
An aminocarboxy aspartic acid-bonded silica (Asp-Silica) stationary phase was synthesized using L-aspartic acid as ligand and silica gel as matrix. The standard protein mixtures were separated with prepared chromatographic column. The effects of solution pH, salt concentration and metal ion on the retention of proteins were examined, and also compared with traditional iminodiacetic acid-bonded silica (IDA-Silica) column. The results show that Asp-Silica column exhibited an excellent separation performance for proteins. The retention of proteins on Asp-Silica stationary phase was consistent with electrostatic characteristic of cation-exchange. The stationary phase displayed typical metal chelate property after fixing copper ion (II) on Asp-Silica. Under competitive eluting condition, protein mixtures were effectively isolated. Asp ligand showed better ion-exchange and metal chelating properties as compared with IDA ligand.
