AIM: To investigate the regulatory mechanism of transforming growth factor-betaon activity of connective tissue growth factor promoter in mouse NIH/3.3.fibroblasts. METHODS: The regulation fragment of the 5' flanking region of the human CTGF gene was linked to pGL3.Basic vector, a firefly luciferase reporter construct without promoter. The recombinant plasmid pCTGF-luc was transiently transfected to NIH/3.3.fibroblasts. The activity of CTGF promoter after treatment of TGF-β1 and MAPK pathway inhibitors were assayed with luciferase reporter gene assay system. RESULTS: TGF-β1-induced increase of CTGF promoter activity was concentration-dependent, with a plateau at 5 μg/L by 2.67-fold vs control (P3.80 (10 μmol/L), the p3. MAP kinaseinhibitor, decreased basal and TGF-β1-induced activation of CTGF promoter. However, inhibition of c-Jun-N-terminal kinase/stress-activated protein kinase by SP600125 (20 μmol/L) was without effect. CONCLUSION: TGF-β1stimulated the transcriptional activity of CTGF gene promoter in NIH/3.3.fibroblasts in a dose- and time-dependent manner. MAPK pathway may play a role in the regulation of TGF-β1-induced CTGF expression.

The second envelope glycoprotein （E2） of hepatitis C virus has been shown to bind human target cells and has become a major target for the development of anti-HCV vaccines. Anti-E2 antibodies have been suggested to be of clinical significance in diagnosis, treatment and prognosis of hepatitis C. However, large-scale expression and purification of E2 proteins in mammalian cells is difficult. As an alternative, E2 fragment （aa 3.5-73.） with a four-amino-acid mutation （aa 568-571 PCNI to RVTS） was expressed as hexa-histidine-tagged full length protein [E2N73.（m）] in E. coli and purified to over 85% purity. Purified E2N73.（m） was specifically recognized by homologous hepatitis C patient serum in Western blot, suggesting that it displayed E2specific antigenicity. Rabbit antiserum raised against E2N73.（m） recognized E2 glyco-proteins expressed in mammalian cells in Western blot. Purified E2N73.（m） was used to detect anti-E2 antibodies in human sera and showed better specificity and sensitivity than previousl

Heart valve diseases threaten human health. One reliable way to save lives of such patients is to replace the pathologically changed heart valves by artificial ones. Over 2 million patients have received LTI-carbon heart valve’s implantation. However, the thrombosis after the implantation is one of the difficulties that need to be solved. In order to improve the blood compatibility and security of mechanical heart valves, ion beam technology was used to modify the surface properties of the materials. The investigation results have been summarized in this paper.

BACKGROUND:Proximal migration of pancreatic stent (PMPS)is an infrequent event but its management can be technically challenging and there are no standard retrieval *** study aimed to determine the results of an endoscopic stent retrieval algorithm in terms of feasibility and efficacy of the endoscopic procedure. METHODS:During the period from January 2008 to December 2009,15 patients(8 women and 7 men with a mean age of 51.9 years)with PMPS were included in this *** retrieval was approached initially with balloon extraction followed by rat-tooth forceps and basket.A rescue approach such as using a stent retriever was attempted when other approaches failed. RESULTS:All the PMPSs(six 5Fr,nine 7Fr)were retrieved successfully within one ERCP *** extraction was successful in 9(60%)*** the 6 failed cases of balloon extraction,wire-guided rat-tooth forceps grasp was successful in 4,and stone extraction basket grasp was successful in 1 in whom forceps grasp *** stent was finally rescued with a stent retriever when balloon extraction,forceps and basket grasp all *** patients with successful balloon extraction,44.4% (4/9)developed post-ERCP hyperamylasemia but none of them developed post-procedure pancreatitis. CONCLUSIONS:With this algorithm,5Fr and 7Fr PMPS were successfully retrieved in all of the *** PMPSs can be safely retrieved with the commonly-used approaches in this *** less used approaches can be used as a rescue method.

Biomarkers are very important indicators of normal and abnormal biological processes. Specific changes in pathologies, biochemistries and genetics can give us comprehensive information regarding the nature of any particular disease. A good biomarker should be precise and reliable, distinguishable between normal and interested disease, and differential between different diseases. It is believed that biomarkers have great potential in predicting chances for diseases, aiding in early diagnosis, and setting standards for the development of new remedies to treat diseases. New technologies have enabled scientists to identify biomarkers of several different neurodegenerative diseases. The followings, for instance, are only a few of the many new biomarkers that have been recently identified: the phosphorylated tau protein and aggregated β-amyloid peptide for Alzheimer’s disease (AD), α-synuclein contained Lewy bodies and altered dopamine transporter (DAT) imaging for Parkinson’s disease (PD), SOD mutations for familial amyotrophic lateral sclerosis (ALS), and CAG repeats resulted from Huntington’s gene mutations in Huntington’s disease (HD). This article will focus on the most-recent findings of biomarkers belonging to the four mentioned neurodegenerative diseases.
