| 1 | Ultrasound/Microbubble Enhances Foreign Gene Expression in ECV304 Cells and Murine Myocardium显示文摘Although viral vectors are efficient systems to transfer foreign genes into cells or target tissues, safety issues remain in relation to human gene therapy. Microbubbles currently used as ultrasound contrast agents have been applied in transfection of genes. This study was designed to test the transfection efficiency and the expression of exogenous gene mediated by ultrasound irradiation enhanced air filled albumin microbubbles in ECV304 cell line in vitro and the heart of the mouse in vivo. Air filled microbubbles (2.0– 4.0 μm in diameter) were created by sonicating the mixture of human albumin, glucose, mannitol and special additive that was designed for stabilization. Plasmid DNA loading the reporter geneswas gently mixed with microbubbles. The mixture of plasmid DNA and microbubbles was administrated to cultured ECV304 cells and BALB/c mice (tail vein injection) under different ultrasound/microbubble conditions, and then the trans- fection and expression efficiency were examined. The results both in vivo and in vitro demonstrated that microbubble with ultrasound irradiation could significantly elevate the exogenous gene expression as compared with microbubble or ultrasound only. Overall, the present study showed that the ultrasound-target microbubble destruction method enhanced the exogenous gene expression in vivo and in vitro, and provided a gene therapy way not only efficient but also easy to be manipulated and carried out in clinical. | DongpingGUO XiaoyuLI PingSUN ZhiguangWANG XiuyingCHEN QiCHEN LemingFAN BinZHANG LizhengSHAO XiaorongLI | 2004 | Acta Biochimica et Biophysica Sinica2004，36，12： | 12 |
| 2 | A Genome Sequence of Novel SARS-CoV Isolates: the Genotype, GD-Ins29, Leads to a Hypothesis of Viral Transmission in South China显示文摘We report a complete genomic sequence of rare isolates (minor genotype) of theSARS-CoV from SARS patients in Guangdong, China, where the first few casesemerged. The most striking discovery from the isolate is an extra 29-nucleotidesequence located at the nucleotide positions between 27,863 and 27,864 (referredto the complete sequence of B J01) within an overlapped region composed of BGI-PUP5 (BGI-postulated uncharacterized protein 5) and BGI-PUP6 upstream ofthe N (nucleocapsid) protein. The discovery of this minor genotype, GD-Ins29,suggests a significant genetic event and differentiates it from the previously re-ported genotype, the dominant form among all sequenced SARS-CoV isolates. A17-nt segment of this extra sequence is identical to a segment of the same size intwo human mRNA sequences that may interfere with viral genome replication andtranscription in the cytosol of the infected cells. It provides a new avenue for theexploration of the virus-host interaction in viral evolution, host pathogenesis, andvaccine development. | E‘deQin XiongleiHe WeiTian YongLiu WeiLi JieWen BingyinSi YongwuHu WenmingPeng LinTaug TaoJiang JianpingShi JiaJia YuZhang JiaYe Cui’eWang YujunHan JingqiangWang BaochangFan QingfaWu GuohuiChang WuchunCao ZuyuanXu RuifuYang JmgWang ManYu YanLi JingXu JunZhou YajumDeng XiaoyuLi JianfeiHu CaipingWang ChunxiaYan QingrunZhang JingyueBao GuoqingLi HaiqingZhang YilinZhang HuiZhao XiaoweiZhang ShuangliLi XiaoJieCheng XiuqingZhang BinLiu ChangqingZeng HuanmingYang WeijunChen LinFang ChangfengLi MengLei DaweiLi WeiTong XiangjunTian JianWang BoZhang SonggangLi XuehaiTan SiqiLiu WeiDong JunWang GaneKa-ShuWong JunYu QingyuZhu | 2003 | Genomics, Proteomics & Bioinformatics2003，1，2： | 6 |
| 3 | Oxypregnane-oligoglycosides from the Stems of Stephanotis mucronata (Asclepiadaceae)显示文摘Four new oxypregnane-oligoglycosides, mucronatosides A (1), B (2), C (3), and D (4), together with one known stephanoside E (5) were isolated from the stems of Stephanotis mucronata (Blanco) Merr.. Their chemical structures were determined on the basis of chemical and extensive spectroscopic methods including one-dimensional and two-dimensional NMR. | RuSongZHANG YiPingYE XiaoYuLI XiaoYingZHANG | 2005 | Chinese Chemical Letters2005，16，4： | 3 |
| 4 | Complete Genome Sequences of the SARS-CoV: the BJ Group (Isolates BJ01-BJ04)显示文摘Beijing has been one of the epicenters attacked most severely by the SARS-CoV (severe acute respiratory syndrome-associated coronavirus) since the first patient was diagnosed in one of the city's hospitals. We now report complete genome sequences of the BJ Group, including four isolates (Isolates B J01, B J02, B J03,and B J04) of the SARS-CoV. It is remarkable that all members of the BJ Group share a common haplotype, consisting of seven loci that differentiate the group from other isolates published to date. Among 42 substitutions uniquely identifled from the BJ group, 32 are non-synonymous changes at the amino acid level.Rooted phylogenetic trees, proposed on the basis of haplotypes and other sequence variations of SARS-CoV isolates from Canada, USA, Singapore, and China, gave rise to different paradigms but positioned the BJ Group, together with the newly discovered GD01 (GD-Ins29) in the same clade, followed by the H-U Group (from Hong Kong to USA) and the H-T Group (from Hong Kong to Toronto), leaving the SP Group (Singapore) more distant. This result appears to suggest a possible transmission path from Guangdong to Beijing/Hong Kong, then to other countries and regions. | ShengliBi E‘deQin ZuyuanXu WeiLi JingWang YongWuHu YongLiu ShuminDuan JianfeiHu YujunHan JingXu YanLi YaoYi YongdongZhou WeiLin1 JieWen HongXu RuanLi ZizhangZhang HaiyanSun JinguiZhu ManYu BaochangFan QingfaWu WeiLin2 LinTang Bao’anYang GuoqingLi WenmingPeng WenjieLi TaoJiang YajunDeng BohuaLiu JianpingShi YongqiangDeng WeiWei HongLiu ZongzhongTong FengZhang YuZhang Cui‘eWang YuquanLi JiaYe YonghuaGan JiaJi XiaoyuLi XiangjunTian FushuangLu GangTan RuifuYang BinLiu SiqiLiu SonggangLi JunWang JianWang WuchunCao JunYu XiaopingDong HuanmingYang | 2003 | Genomics, Proteomics & Bioinformatics2003，1，3： | 1 |
| 5 | Kinetics of the Phenotype and Function of Murine Peritoneal Macrophages Following Acute Inflammation显示文摘This study was undertaken to have a better understand for the process and the underlying mechanisms to limit macrophage activation and population of activated macrophages. A comprehensive kinetics of cytokine production was performed in murine peritoneal macrophages recovered from Balb/c mice at various time during the course of an intraperitoneal injection with thioglycollate (TG). The expression of cell surface molecules such as MHC-Ⅰ, MHC-Ⅱ, B7-1 and B7-2 of these macrophages were also determined by flow cytometry. The present findings of our research suggested that the population of activated macrophages and the activation of macrophages (including cytokines production and expression of cell surface functional molecules)were strictly controlled during inflammation process. This is one of the important mechanisms to retain the host homeostasis.
