| 1 | Oncofetal antigen glypican-3 as a promising early diagnostic marker for hepatocellular carcinoma显示文摘BACKGROUND:Hepatocellular carcinoma (HCC) is characterized by a multi-cause,multi-stage and multi-focus process of tumor progression.Its prognosis is poor and early diagnosis is of utmost importance.This study was undertaken to investigate the dynamic expression of oncofetal antigen glypican-3 (GPC-3) and GPC-3 mRNA in hepatocarcinogenesis and to explore their early diagnostic value for HCC.METHODS:A hepatoma model was induced in male Sprague-Dawley rats with 0.05% 2-fluorenylacetamide and confirmed by hematoxylin and eosin staining and gamma-glutamyltransferase (GGT) expression.Total RNA was purified and transcribed into cDNA by reverse transcription.Fragments of the GPC-3 gene were amplified by nested RT-PCR,and confirmed by sequencing.GPC-3 was analyzed by immunohistochemistry,Western blotting or ELISA.RESULTS:Positive GPC-3 expression showed as brown granule-like staining localized in the cytoplasm.Histological examination of hepatocytes revealed three morphological stages of granule-like degeneration,atypical hyperplasia (precancerous),and cancer formation,with a progressive increase of liver total RNA and GGT expression.The incidence of liver GPC-3 mRNA and GPC-3,and serum GPC-3 was 100%,100% and 77.8% in the HCC group,100%,100%,and 66.7% in the precancerous group,83.3%,83.3%,and 38.9% in the degeneration group,and no expression in the liver or blood of the control group,respectively.There was a positive correlation between liver GPC-3 mRNA and total RNA level (r=0.475,P<0.05) or liver GPC-3 (r=1.0,P<0.001) or serum GPC-3 (r= 0.994,P<0.001).CONCLUSION:Abnormal oncofetal antigen GPC-3 and GPC-3 mRNA expression in hepatocarcinogenesis may be promising molecular markers for early diagnosis of HCC. | Research Center of Clinical Medicine,Affiliated Hospital of Nantong University,Nantong 226001,China (Yao M,Yao DF,Qiu LW,Wu W,Sai WL,Yang JL and Zhang HJ) Department of Oncology,Yancheng First People’s Hospital,Yancheng 224001,China (Bian YZ) Department of Oncology,Second Affiliated Hospital,Nanjing Medical University,Nanjing 210011,China (Zhang CG) | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，3： | 51 |
| 2 | CASE-BASED PRODUCT CONFIGURATION AND REUSE IN MASS CUSTOMIZATION显示文摘The increasing complexity and size of configuration knowledge bases requires the provision of advanced methods supporting the development of the actual configuration process and design reuse.A new framework to find a feasible and practical product configuration method is presented in mass customization.The basic idea of the approach is to integrate case-based reasoning (CBR) with a constraint satisfaction problem(CSP).The similarity measure between a crisp and range is also given,which is common in case retrieves.Based on the configuration model,a product platform and customer needs,case adaptation is carried out with the repair-based algorithm.Lastly,the methodology in the elevator configuration design domain is tested. | Wang Shiwei Tan Jianrong Zhang Shuyou Wang Xin He Chenqi State Key Laboratory of CAD&CG,Zhejiang University,Hangzhou 310027, China | 2004 | Chinese Journal of Mechanical Engineering2004，17，2： | 39 |

| 6 | Geometric construction of energy-minimizing Bézier curves显示文摘Modeling energy-minimizing curves have many applications and are a basic problem of Geometric Modeling.In this paper,we propose the method for geometric design of energy-minimizing B′ezier curves.Firstly,the necessary and sufficient condition on the control points for B′ezier curves to have minimal internal energy is derived.Based on this condition,we propose the geometric constructions of three kinds of B′ezier curves with minimal internal energy including stretch energy,strain energy and jerk energy.Given some control points,the other control points can be determined as the linear combination of the given control points.We compare the three kinds of energy-minimizing B′ezier curves via curvature combs and curvature plots,and present the collinear properties of quartic energy-minimizing B′ezier curves.We also compare the proposed method with previous methods on efficiency and accuracy.Finally,several applications of the curve generation technique,such as curve interpolation with geometric constraints and modeling of circle-like curves are discussed. | XU Gang 1,4,5,WANG GuoZhao 2 & CHEN WenYu 2,3 1 Institute of Graphics and Image,Hangzhou Dianzi University,Hangzhou 310018,China 2 Department of Mathematics,Zhejiang University,Hangzhou 310027,China 3 School of Computer Engineering,Nanyang Technological University,639798,Singapore 4 Galaad,INRIA Sophia-Antipolis,2004 Route des Lucioles,06902,France 5 State Key Lab of CAD & CG,Zhejiang University,Hangzhou 310027,China | 2011 | Science China(Information Sciences)2011，54，7： | 15 |

| 11 | Chemoprotective effects of curcumin in esophageal epithelial cells exposed to bile acids显示文摘AIM:To investigate the ability of curcumin to counteract the impact of bile acids on gene expression of esophageal epithelial cells.METHODS:An esophageal epithelial cell line(HET1A)was treated with curcumin in the presence of deoxycholic acid.Cell proliferation and viability assays were used to establish an appropriate dose range for curcumin.The combined and individual effects of curcumin and bile acid on cyclooxygenase-2(COX-2)and superoxide dismutase(SOD-1 and SOD-2)gene expression were also assessed.RESULTS:Curcumin in a dose range of 10-100μmol/L displayed minimal inhibition of HET-1A cell viability.Deoxycholic acid at a concentration of 200μmol/L caused a 2.4-fold increase in COX-2 gene expression compared to vehicle control.The increased expression of COX-2 induced by deoxycholic acid was partially reversed by the addition of curcumin,and curcumin reduced COX-2 expression 3.3-to 1.3-fold.HET-1A cells exposed to bile acid yielded reduced expression of SOD-1 and SOD-2 genes with the exception that high dose deoxycholic acid at 200μmol/L led to a 3-fold increase in SOD-2 expression.The addition of curcumin treatment partially reversed the bile acid-induced reduction in SOD-1 expression at all concentrations of curcumin tested.CONCLUSION:Curcumin reverses bile acid suppression of gene expression of SOD-1.Curcumin is also able to inhibit bile acid induction of COX-2 gene expression. | Matthew R Bower Harini S Aiyer Robert CG Martin Yan Li | 2010 | World Journal of Gastroenterology2010，16，33： | 10 |

| 13 | Precision ERS-2 orbit deter-mination combining multiple tracking techniques显示文摘Both of the oceanographic research by using altimetry and the application of InSAR of ERS-2 satellite need the precise ephemerides of the satellite. In this note, the ERS-2 orbit is precisely determined by using SLR and PRARE observations to take advantage of the high accuracy of SLR and the widespread data coverage of PRARE. Based on the software system SODS-VCE established by us, the ERS-2 orbits in 1997 are calculated. The evaluation from tracking data fits, endpoint consistency of orbital arcs and comparison with independent orbit implies an orbit accuracy of 5-6 cm in radial component which can satisfy the requirement of being better than 10 cm in oceanographic research by altimetry, being less than 20 cm in cross-track component which can meet the requirement of InSAR. In orbit computation, the method of variance component estimation is employed to weight the SLR, PRARE range and Doppler measurements properly. The results indicate that the application of the method can improve the computation | Zhang, FP Huang, C Liao, XH Feng, CG | 2001 | Chinese Science Bulletin2001，46，20： | 7 |

| 19 | Diagnostic imaging and radiation exposure in inflammatorybowel disease显示文摘Diagnostic imaging plays a key role in the diagnosis and management of inflammatory bowel disease(IBD). However due to the relapsing nature of IBD, there is growing concern that IBD patients may be exposed to potentially harmful cumulative levels of ionising radiation in their lifetime, increasing malignant potential in a population already at risk. In this review we explore the proportion of IBD patients exposed to high cumulative radiation doses, the risk factors associated with higher radiation exposures, and we compare conventional diagnostic imaging with newer radiation-free imaging techniques used in the evaluation of patients with IBD. While computed tomography(CT) performs well as an imaging modality for IBD, the effective radiation dose is considerably higher than other abdominal imaging modalities. It is increasingly recognised that CT imaging remains responsible for the majority of diagnostic medical radiation to which IBD patients are exposed. Magnetic resonance imaging(MRI) and small intestine contrast enhanced ultrasonography(SICUS) have now emerged as suitable radiation-free alternatives to CT imaging, with comparable diagnostic accuracy. The routine use of MRI and SICUS for the clinical evaluation of patients with known or suspected small bowel Crohn's disease is to be encouraged wherever possible. More provision is needed for out-of-hours radiation-free imaging modalities to reduce the need for CT. | Nekisa Zakeri Richard CG Pollok | 2016 | World Journal of Gastroenterology2016，22，7： | 4 |
| 20 | Electro-mechanical response of functionally graded beams with imperfectly integrated surface piezoelectric layers显示文摘The time-dependent behavior of a simply-supported functionally graded beam bonded with piezoelectric sensors and actuators is studied using the state-space method. The creep behavior of bonding adhesives between piezoelectric layers and beam is characterized by a Kelvin-Voigt viscoelastic model, which is practical in a high temperature circumstance. Both the host elastic functionally graded beam and the piezoelectric layers are orthotropic and in a state of plane stress, with the former being inhomogeneous along the thickness direction. A laminate model is employed to approximate the host beam. Moreover, the coupling effect between the elastic deformation and electric field in piezoelectric layers is considered. Results indicate that the viscoelastic property of interfacial adhesives has a significant effect on the function of bonded actuators and sensors with time elapsing. | YAN Wei1 & CHEN Weiqiu1,2 1.
