Objective Transporter associated with antigen processing(TAP) has essential roles in the antigenpresenting systems,translocating antigenic peptides from the cytosol into the endoplasmic reticulum. Genetic polymorphisms of TAP gene may be involved in the outcomes of HCV infection.A casecontrol study was conducted to test this *** Total 173 drug users(DUs) with HCV persistent infection,189 DUs with HCV self-limiting infection,and 225 DUs with HCV uninfection were obtained during the one-year period(2006.01-2006.12).Antibodies to HCV antigens were detected by enzyme-linked *** presence of viral particles in the serum was determined by reverse -transcriptase polymerase chain reaction(RT-PCR).The genotypes of six polymorphisms of TAP gene were analyzed by ARMS-PCR *** Of the six polymorphisms,one of which(TAP2-379) was observed to have statistically significant association with recovered HCV infection(P37 and TAP2-379) were observed to have statistically significant association with persistent HCV infection(P37) was observed to have statistically significant association with outcomes of HCV infection(P<0.05).The extended haplotype constructed with TAP polymorphisms was analyzed among the healthy control,recovered and persistent *** TAP2 haplotype H(Ile-Ala-Arg-Thr) and K(Ile-Thr-Arg-Thr) were shown to present significant difference between the recovered and control groups(P<0.05).TAP1 haplotype B(Ile-Gly),D(Val -Gly),and TAP2 haplotype E(Val-Thr-Arg-Thr),H(De-Ala-Arg-Thr) were shown to present significant differences between the persistent and control groups(P<0.05).The frequency of TAP1 haplotype B(De-Gly) or D(Val-Gly) was found increased significantly in persistent group,in comparison with that in recovered group(P<0.05).Conclusions These findings suggest a potential role of TAP2 gene as a candidate gene for susceptibility to HCV *** the genetic polymorphism

Journal of Electronic Science and Technology of china 2004年第3期2卷 1-5页

作者： CHEN Jian, LIU Yunhui, SONG Xiping (school of Economics and Management, Tsinghua university Beijing 100084 china department of System Engineering and Engineering Management, The Chinese university of Hong Kong Shatin NT Hong Kong china) school of Economics and Management Tsinghua University Beijing 100084 China department of System Engineering and Engineering Management The Chinese University of Hong Kong Shatin NT Hong Kong China

Demand uncertainty is a key factor for the seller's decision making, especially in the e-business environment, for the website to sell products through the online auction. In this paper, two kinds of demand uncertainties are considered: the consumer regime uncertainty and the inherent randomness of the market environment. Then, how to use a novel business model and group-buying auction (GBA) is analyzed in such a market environment. Based on the comparison of the GBA and the posted price mechanism, some conditions that favor the GBA are provided.
