OBJECTIVETo comparatively study the effects of Rhubarbs from different regions on blood lipid and antioxi dation of hyperlipidemia rats.
METHODSMale rats were randomly divided into 9 groups ( n = 8) and fed with high-fat diet to replicate the hyperlipidemia model. Meanwhile, Rheum tanguticum was administrated intragastrically at two doses (3.0 g/kg and 1.0 g/kg), once a day for continuous 28 days. The effects of Rheum tanguticum planted in Gannan (RT-GN), Rheum tanguticum planted in Xinin (RT-XN) and Rheum plmatum planted in Lixian (RP-LX) were evaluated through detecting the parameters of blood lipids, blood viscosity and antioxidant system.
RESULTST-GN, RT-XN and RP-LX in the range of 1.0-3.0 g/kg could decrease the blood levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and malonaldehyde (MDA) in blood. Besides, they could reduce blood viscosity, increase high density lipoprotein (HDL) level and upregulate the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). Interestingly, their effects on blood viscosity was obviously in a dose dependent manner. In addition, the effects of RT-GN on LDL, MDA and blood viscosity were not significantly different from those of RT-XN and better than those of RP-LX.
CONCLUSIONThe RT has better hypolipidemic effects than the RP, but RT-GN and RT-XN are not different from the above effects.

Objective To analyze the expression level of CD44v6 in small cell lung cancer and the concentration of vascular endothelial growth factor(VEGF) in serum,to explore the clinical significance of them in small cell lung cancer.Methods The expression level of CD44v6 was detected by immunohistochemical methods in 80 cases of small cell lung cancer as patients group,who were treat in People''s Hospital of Jiangyin from January 2014 to January 2016.Another 80 cases of healthy subjects as control group.Used ELISA method to detect the concentration of VEGF of the two groups of patients in the blood.Analyzed the relationship between VEGF,CD44v6 with the survival time of patients.Results The CD44v6 expression in small cell lung cancer was positive in 6 cases,the total positive expression rate was 7.5%.The serum levels of VEGF in patients group((490.9±342.7) ng/L) was significantly different from that in the control group((180.8±67.5) ng/L),and the difference was statistically significant(P=0.024).There was no correlation between the survival time and the expression of CD44v6 in small cell lung cancer(P=0.723).The survival time of small cell lung cancer was negatively correlated with the concentration of VEGF in serum.Conclusion There is a significant correlation between serum VEGF concentration and survival time in patients with small cell lung cancer,which is one of the prognostic factors in patients with small cell lung cancer.

Objective To study the exact function of human gene 5 transactivated by pre-S1 protein of hepatitis B virus(PS1TP5)by investigating the gene expression of PS1TP5 in yeast cells. Methods Reverse transcription-polymerase chain reaction(RT-PCR)was performed to amplify the gene of PS1TP5 using the mRNA of HepG2 cells as template and the gene was cloned into pGEM-T vector.The gene of PS1TP5 was cut from pGEM-T-PS1TP5 vector and cloned into yeast expressive plasmid pGBKT7,then pGBKT7-PS1TP5 was transformed into yeast cell AH109.The yeast protein was isolated and analyzed with sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE) and Western hybridization.Results PS1TP5 gene was successfully amplified and identified by DNA sequencing.The digested fragment was cloned into pGBKT7 vector and transformed into yeast cell AH109.The results of SDS-PAGE and Western assay showed that the relative molecular weight of the expressed product was about 36 950,and PS1TP5 protein existed in yeast cells.Conclusion The findings suggest that PS1TP5 can be successfully expressed in yeast cell.

OBJECTIVETo screen and identify differentially expressed proteins of mesenchymal stem cells (MSC) during endothelial differentiation.
METHODSMSCs were induced to endothelial differentiation with vascular endothelial growth factor (VEGF) and epithelial growth factor (EGF) mixture. The whole cell proteins were extracted and isolated by two-dimensional gel electrophoresis. After gel was analyzed by Imagemaster 5.0 software, differentially expressed proteins were partially selected and identified by MALDI-TOF-MS.
RESULTSThe differentiated MSC highly expressed endothelial cells related markers, CD31, CD34 and FVIIIAg were 56.8%, 38.8% and 14.5% respectively by flow cytometer. Compared with the primary cultured MSC, the differentiated cells differentially expressed 91 proteins. Among the 19 identified proteins, 11 up-regulated and 8 down-regulated, which include cytoskeletal proteins, such as myosin, filamin, vimentin and vinculin; cell metabolism enzymes, such as ORP-150, ERO1-α, Delta(3,5)-Delta(2,4)-dienoyl-CoA isomerase, protein disulfide-isomerase A3, FAS and enolase 3; nuclear factors, such as TAR DNA binding protein, guanine nucleotide binding protein and hypoxia up-regulated protein 1; VEGF receptors, such as KDR and so on.
CONCLUSIONSCytoskeletal proteins, metabolism enzymes and KDR were all involved in endothelial differentiation of MSC. These proteins may be the regulatory targets for endothelial differentiation of MSC.

Endometriosis (EM) is one of the most common gynaecological disorder affecting women in their reproductive age. Mechanisms involved in the pathogenesis of EM remains poorly understood, however inflammatory responses have been reported to be significantly involved. The efficacy of 6-shogaol on proliferation of endometriotic lesions and inflammatory pathways in experimentally-induced EM model was explored in this study. EM was stimulated in Sprague-Dawley rats by implantation of autologous endometrium onto the peritoneum abdominal wall. Separate groups were treated with 6-shogaol (50, 100 or 150 mg/kg b.wt/day) via oral gavage for one month period. Gestrinone (GTN) group received GTN (0.5 mg/kg/day) as positive control. Five weeks after implantation, the spherical volume of ecto-uterine tissues was determined. Treatment with 6-shogaol significantly reduced the implant size. Histological analysis reported atrophy and regression of the lesions. 6-shogaol administration effectively down-regulated NF-κB signaling, VEGF and VEGFR-2 (Flk-1) expression in the endometriotic lesions. Excess production of IL-1β and IL-6 (pro-inflammatory cytokines), PGE2 and nitric oxide (NO) were reduced. Overall, the results of the study reveal the efficacy of 6-shogaol against endometriosis via effectively suppressing proliferation of the lesions and modulating angiogenesis and COX-2/NF-κB-mediated inflammatory cascades.

OBJECTIVETo construct a eukaryotic expression vector of transmembrane-4-L-six-family-1 (TM4SF1) gene and study its effect on the migration and invasion of colorectal cancer cells.
METHODSA pair of specific primers of TM4SF1 gene (GenBank: BC034145.1) was used to acquire the open reading frame of TM4SF1 by RT-PCR. The amplified sequence was ligated to a PEZ-M29 vector, which, after identification, was transiently transfected in colorectal cancer cell lines HCT116 and DLD1. Western blotting and immunocytochemistry were used to analyze the transfection efficiency, and scratch and Transwell tests were performed to analyze the changes in the migration and invasion of HCT116 and DLD1 cells after transfection.
RESULTSCell scratch and Transwell assays revealed that transfection with the recombinant plasmid, PEZ-M29/TM4SF1, caused up-regulated expression of TM4SF1 and promoted the migration and invasion of HCT116 and DLD1 cells.
CONCLUSIONOur results demonstrated that TM4SF1 is closely related to the invasion and metastasis of colorectal cancer cells in vitro.
