| 1 | Identification of a novel coronavirus causing severe pneumonia in human:a descriptive study显示文摘Background:Human infections with zoonotic coronaviruses(CoVs),including severe acute respiratory syndrome(SARS)-CoV and Middle East respiratory syndrome(MERS)-CoV,have raised great public health concern globally.Here,we report a novel batorigin CoV causing severe and fatal pneumonia in humans.Methods:We collected clinical data and bronchoalveolar lavage(BAL)specimens from five patients with severe pneumonia from Wuhan Jinyintan Hospital,Hubei province,China.Nucleic acids of the BAL were extracted and subjected to next-generation sequencing.Virus isolation was carried out,and maximum-likelihood phylogenetic trees were constructed.Results:Five patients hospitalized from December 18 to December 29,2019 presented with fever,cough,and dyspnea accompanied by complications of acute respiratory distress syndrome.Chest radiography revealed diffuse opacities and consolidation.One of these patients died.Sequence results revealed the presence of a previously unknownβ-CoV strain in all five patients,with 99.8%to 99.9%nucleotide identities among the isolates.These isolates showed 79.0%nucleotide identity with the sequence of SARS-CoV(GenBank NC_004718)and 51.8%identity with the sequence of MERS-CoV(GenBank NC_019843).The virus is phylogenetically closest to a bat SARS-like CoV(SL-ZC45,GenBank MG772933)with 87.6%to 87.7%nucleotide identity,but is in a separate clade.Moreover,these viruses have a single intact open reading frame gene 8,as a further indicator of bat-origin CoVs.However,the amino acid sequence of the tentative receptor-binding domain resembles that of SARS-CoV,indicating that these viruses might use the same receptor.Conclusion:A novel bat-borne CoV was identified that is associated with severe and fatal respiratory disease in humans. | Li-Li Ren Ye-Ming Wang Zhi-Qiang Wu Zi-Chun Xiang Li Guo Teng Xu Yong-Zhong Jiang Yan Xiong Yong-Jun Li Xing-Wang Li Hui Li Guo-Hui Fan Xiao-Ying Gu Yan Xiao Hong Gao Jiu-Yang Xu Fan Yang Xin-Ming Wang Chao Wu Lan Chen Yi-Wei Liu Bo Liu Jian Yang Xiao-Rui Wang Jie Dong Li Li Chao-Lin Huang Jian-Ping Zhao Yi Hu Zhen-Shun Cheng Un-Lin Liu Zhao-Hui Qian Chuan Qin Qi Jin Bin Cao Jian-Wei Wang | 2020 | Chinese Medical Journal2020,,9: | 99 |
| 2 | A complete sequence and comparative analysis of a SARS-associated virus(Isolate BJ01)显示文摘The genome sequence of the Severe Acute Respiratory Syndrome (SARS)-associated virus provides essential information for the identification of pathogen(s), exploration of etiology and evolution, interpretation of transmission and pathogenesis, development of diagnostics, prevention by future vaccination, and treatment by developing new drugs. We report the complete genome sequence and comparative analysis of an isolate (BJ01) of the coronavirus that has been recognized as a pathogen for SARS. The genome is 29725 nt in size and has 11 ORFs (Open Reading Frames). It is composed of a stable region encoding an RNA-dependent RNA polymerase (composed of 2 ORFs) and a variable region representing 4 CDSs (coding sequences) for viral structural genes (the S, E, M, N proteins) and 5 PUPs (putative uncharacterized proteins). Its gene order is identical to that of other known coronaviruses. The sequence alignment with all known RNA viruses places this virus as a member in the family of Coronaviridae. Thirty putative substitutions have been identified by comparative analysis of the 5 SARS- associated virus genome sequences in GenBank. Fifteen of them lead to possible amino acid changes (non-synonymous mutations) in the proteins. Three amino acid changes, with predicted alteration of physical and chemical features, have been detected in the S protein that is postulated to beinvolved in the immunoreactions between the virus and its host. Two amino acid changes have been detected in the Mprotein, which could be related to viral envelope formation. Phylogenetic analysis suggests the possibility of non-human origin of the SARS-associated viruses but provides noevidence that they are man-made. Further efforts should focus on identifying the etiology of the SARS-associated virus and ruling out conclusively the existence of otherpossible SARS-related pathogen(s). | QIN E'de ZHU Qingyu YU Man FAN Baochang CHANG Guohui SI Bingyin YANG Bao PENG Wenming JIANG Tao LIU Bohua DENG Yongqiang LIU Hong ZHANG Yu WANG Cui LI Yuquan GAN Yonghua LI Xiaoyu L Fushuang TAN Gang CAO Wuchun, YANG Ruifu Institute of Microbiology and Epidemiology, Chinese Academy of Military Medical Sciences, Beijing 100071, China WANG Jian, LI Wei, XU Zuyuan, LI Yan, WU Qingfa, LIN Wei, CHEN Weijun, TANG Lin, DENG Yajun, HAN Yujun, LI Changfeng, LEI Meng, LI Guoqing, LI Wenjie, L Hong, SHI Jianping, TONG Zongzhong, ZHANG Feng, LI Songgang, LIU Bin, LIU Siqi, DONG Wei, WANG Jun, Gane K-S Wong, YU Jun & YANG Huanming* Beijing Genomics Institute, Chinese Academy of Sciences, Beijing 101300 National Center for Genome Information, Beijing 101300, China | 2003 | Chinese Science Bulletin2003,48,10: | 121 |

| 5 | Volumetric-modulated arc therapy vs c-IMRT in esophageal cancer:A treatment planning comparison显示文摘AIM:To compare the volumetric-modulated arc therapy AT plans ith conventional sliding indo intensity-modulated radiotherapy c-I RT plans in esophageal cancer EC . METHODS:Tenty patients ith EC ere selected, including 5 cases located in the cervical, the upper, the middle and the lo er thorax, respectively. Five plans ere generated ith the eclipse planning system:three using c-IMRT with 5 fields (5F), 7 fields (7F) and 9 fields (9F), and two using VMAT with a single arc 1A and double arcs 2A . The treatment plans ere designed to deliver a dose of 60 Gy to the plan-ning target volume Tith the same constrains in a 2.0 Gy daily fraction, 5 d a eek. lans ere normalized to 95% of the T that received 100% of the prescribed dose. We examined the dose-volume histogram parameters of T and the organs at risk OAR such as lungs, spinal cord and heart. onitor units U and normal tissue complication probability NTC of OAR ere also reported. RESULTS:Both c-I RT and AT plans resulted in abundant dose coverage of T for EC of different locations. The dose conformity to T as improved as the number of field in c-IMRT or rotating arc in VMAT as increased. The doses to T and OAR in AT plans ere not statistically different in comparison ith c-I RT plans, ith the follo ing exceptions:in cervical and upper thoracic EC, the conformity index CI as higher in VMAT (1A 0.78 and 2A 0.8) than in c-IMRT (5F 0.62, 7F 0.66 and 9F 0.73) and homogeneity was slightly better in c-IMRT (7F 1.09 and 9F 1.07) than in VMAT (1A 1.1 and 2A 1.09). Lung V30 was lower in VMAT (1A 12.52 and 2A 12.29) than in c-IMRT (7F 14.35 and 9F 14.81). The humeral head doses were significantly increased in AT as against c-I RT. In the middle and lower thoracic EC, CI in VMAT (1A 0.76 and 2A 0.74) was higher than in c-IMRT (5F 0.63 Gy and 7F 0.67 Gy), and homogeneity was almost similar bet een AT and c-I RT. 20 2A 21.49 Gy vs 7F 24.59 Gy and 9F 24.16 Gy) and V30 (2A 9.73 Gy vs 5F 12.61 Gy, 7F 11.5 Gy and 9F 11.37 Gy) of lungs in AT ere lo er than in c-I RT, but lo doses to lungs (V5 and V10) were increased. V30 (1A 48.12 Gy vs 5F 59.2 Gy, 7F 58.59 Gy and 9F 57.2 Gy), V40 and 50 of heart in AT as lo er than in c-I RT. Us in AT plans ere significantly reduced in comparison ith c-I RT, maximum doses to the spinal cord and mean doses of lungs ere similar bet een the t o techniques. NTC of spinal cord as 0 for all cases. NTC of lungs and heart in AT ere lo er than inc-I RT. The advantage of AT plan as enhanced by doubling the arc. CONCLUSION:Compared ith c-I RT, AT, especially the 2A, slightly improves the OAR dose sparing, such as lungs and heart, and reduces NTC and U ith a better T coverage. | Li Yin Hao Wu Jian Gong Jian-Hao Geng Fan Jiang An-Hui Shi Rong Yu Yong-Heng Li Shu-Kui Han Bo Xu Guang-Ying Zhu | 2012 | World Journal of Gastroenterology2012,18,37: | 34 |
| 6 | Geochemical characteristics of pore water in shallow sediments from Shenhu area of South China Sea and their significance for gas hydrate occurrence显示文摘The Shenhu area is one of the promise target areas for marine gas hydrate exploration in the northern margin of the South China Sea.Pore water samples were collected from two piston cores (8.75 and 8.52 m) in site HS-A and site HS-B in the Shenhu area,and their major anion and cation contents and trace element contents have been analyzed in this study.Cl- concentrations in pore waters are similar to the seawater value and no systematic change along depth profiles has been found for the Cl- content in both sites.In site HS-A,the SO 2- 4 contents show a limited range in pore waters from 0 to 3 m depths,but a dramatic decrease is documented in depth below 3 m.Other elements such as Ca 2+,Mg 2+ and Sr 2+ show similar variation patterns as the SO 2- 4,i.e.,no variation in 0-3 m,but large decrease in depth below 3 m.In site HS-B,both the SO 4 and Ca 2+,Mg 2+ and Sr 2+ display a decrease pattern along the depth profile,but in 0-3 m the variation is less significant than those in depth below 3 m.In both sites HS-A and HS-B,I contents show a dramatic increase along depth profiles.Calculations show that the SMI depths are very shallow (10 and 11 m) in both sites,and the sulfate flux and I flux are very high.These geochemical characteristics and anomalies at Shenhu are quite similar to those found in other gas hydrate locations in the world,and a genetic link is suggested to be related to the gas hydrate occurrence at depths in the study area.In summary,we suggest that combined geochemical parameters in shallow sediment pore waters are useful indicators to indicate the gas hydrate occurrence at depths. | YANG Tao JIANG ShaoYong GE Lu YANG JingHong WU NengYou ZHANG GuangXue LIU Jian | 2010 | Chinese Science Bulletin2010,55,8: | 30 |
| 7 | The Association of Maternal Body Composition and Dietary Intake with the Risk of Gestational Diabetes Mellitus during the Second Trimester in a Cohort of Chinese Pregnant Women显示文摘Objective To investigate the association of maternal body composition and dietary intake with the risk of gestational diabetes mellitus(GDM). Methods A total 154 GDM subjects and 981 controls were enrolled in a prospective cohort study in 11 hospitals from May 20, 2012 to December 31, 2013. Bioelectrical impedance analysis and dietary surveys were used to determine body composition and to evaluate the intake of nutrients in subjects at 21-24 weeks' gestation(WG). Logistic regression analysis was applied to explore the relationships of maternal body composition and dietary intake with the risk of GDM morbidity. Results Age, pre-pregnant body weight(BW), and body mass index(BMI) were associated with increased risk of GDM. Fat mass(FM), fat mass percentage(FMP), extracellular water(ECW), BMI, BW, energy, protein, fat, and carbohydrates at 21-24 WG were associated with an increased risk of GDM. In contrast, fat free mass(FFM), muscular mass(MM), and intracellular water(ICW) were associated with a decreased risk of GDM. Conclusion Maternal body composition and dietary intake during the second trimester of pregnancy were associated with the risk of GDM morbidity. | Xu Qing Gao Zhi Ying Li Li Ming Wang Lu Zhang Qian Teng Yue Zhao Xia Ge Sheng Jing Hong Jiang Yang Yong Tao Liu Xiao Jun Lyu Chun Jian Mao Lun Yu Xiao Ming Liu Ying Hua Kong Ai Jing Yang Xue Yan Liu Zhao Zhang Yong Wang Jin Zhang Xin Sheng Xue Chang Yong Lu Yan Ping | 2016 | Biomedical and Environmental Sciences2016,29,1: | 29 |
| 8 | Serum pepsinogen Ⅱ is a better diagnostic marker in gastric cancer显示文摘AIM:To investigate screening makers for gastric cancer,we assessed the association between gastric cancer and serum pepsinogens(PGs).METHODS:The subjects comprised 450 patients with gastric cancer,111 individuals with gastric atrophy,and 961 healthy controls.Serum anti-Helicobacter pylori(H.pylori) immunoglobulin G(IgG),PGⅠand PG Ⅱ were detected by enzyme-linked immunosorbent assay.Gastric atrophy and gastric cancer were diagnosed by endoscopy and histopathological examinations.Odds ratios and 95%CIs were calculated using multivariate logistic regression.RESULTS:Rates of H.pylori infection remained high in Northeastern China.Rates of H.pylori IgG positivity were greater in the gastric cancer and gastric atrophy groups compared to the control group(69.1% and 75.7% vs 49.7%,P < 0.001).Higher levels of PG Ⅱ(15.9 μg/L and 13.9 μg/L vs 11.5 μg/L,P < 0.001) and lower PGⅠ/PG Ⅱ ratio(5.4 and 4.6 vs 8.4,P < 0.001) were found in patients with gastric cancer or gastric atrophy compared to healthy controls,whereas no correlation was found between the plasma PGⅠconcentration and risk of gastric cancer(P = 0.537).In addition,multivariate logistic analysis indicated that H.pylori infection and atrophic gastritis were independent risk factors for gastric cancer.Lower plasma PGⅠ/PG Ⅱ ratio was associated with higher risks of atrophy and gastric cancer.Furthermore,plasma PG Ⅱ?level?significantly?correlated?with?H.pyloriinfected gastric cancer.CONCLUSION:Serum PG Ⅱ concentration and PG Ⅰ/PG Ⅱ ratio are potential biomarkers for H.pyloriinfected gastric disease.PG Ⅱ is independently associated with risk of gastric cancer. | Xue-Yuan Cao Zhi-Fang Jia Mei-Shan Jin Dong-Hui Cao Fei Kong Jian Suo Jing Jiang | 2012 | World Journal of Gastroenterology2012,18,48: | 27 |

| 10 | Panax notoginseng saponins ameliorates experimental hepatic fibrosis and hepatic stellate cell proliferation by inhibiting the Jak2/Stat3 pathways显示文摘OBJECTIVE: To investigate the inhibitory effect of Panax notoginseng saponins(PNS) on liver fibrosis and explore the underlying mechanisms.METHODS: Carbon tetrachloride(CCl4)-treated rats and hepatic stellate cells(HSCs) were used. The effect of PNS on CCl4-induced liver fibrosis was studied with histochemical and biochemical analysis.Transforming growth factor(TGF)-β1, α-smooth muscle actin(α-SMA), and collagen Ι m RNA expression were determined by reverse transcriptase-polymerase chain reaction(RT-PCR). Meanwhile, the protein expression levels of α-SMA, collagen Ι, phosphorylation-Janus activated kinase signal transducer(p-Jak2) / Jak2, and phosphorylation-activator of transcription(p-Stat)3 / Stat3 were determined by immunohistochemistry and / or immunoblotting.RESULTS: PNS treatment significantly improved the liver function of rats as indicated by decreased serum enzymatic activities of alanine aminotransferase and aspartate aminotransferase. Histopathological results indicated that PNS alleviated liver damage and reduced the formation of fibrous septa. Moreover, PNS significantly decreased liver hydroxyproline and significantly attenuated expressions of collagen Ⅰ, α-SMA, TGF-β1, p-Jak2 / Jak2,and p-Stat3 / Stat3 in the rat liver fibrosis model and HSCs.CONCLUSION: PNS can relieve liver fibrosis by modulating Jak2/Stat3 signaling transduction pathway, which may be one of its mechanisms to suppress hepatic fibrosis. | Jiang Hui Gao Jiarong Wang Yongzhong Zhang Jiafu Han Yanquan Wei Liangbing Liu Xiaochuang Wu Jian | 2016 | Journal of Traditional Chinese Medicine2016,36,2: | 28 |
| 11 | Expression of miR-125b in the new,highly invasive glioma stem cell and progenitor cell line SU3显示文摘MicroRNA (miR)-125b has been shown to play a potential role in the development of glioma stem cells.However,the relationship between miRNA and glioma stem cells is still elusive.This study was designed to elucidate this potential relationship.We established a highly invasive glioma stem cell and progenitor (GSCP) cell line SU3.SU3 cell suspensions were injected into nude mice brains in situ,and the invasiveness of graft tumors was analyzed using hematoxylin and eosin staining as well as immunohistochemistry.Real-time polymerase chain reaction (PCR) was used to measure the expression levels of miR-125b in SU3 and other cells.In vitro,SU3 cells expressed CD133 and nestin as well as differentiation markers glial fibrillary acidic protein (GFAP) and β-tubulin III,which were consistent with the characteristics of glioma stem cells.Scratch assays indicated that the migration ability of SU3 cells was stronger than that of U251 stem cells (U251s).In vivo,SU3 cells invaded into each part of the mouse brain from the caudate nucleus in a diffuse pattern and highly expressed invasive and proliferative cell markers matrix metalloprotease 2 (MMP2),MMP9,and Ki-67.Real-time PCR results revealed that the levels of miR-125b and MMP9 were significantly higher in SU3 and SU2,also a highly invasive GSCP cell line we established before,than in U251s.High expression of miR-125b both in newly established GSCPs,SU3,and long-term cultured GSCPs,SU2 suggests that miR-125b exhibits oncogene-like behavior.This behavior should be considered in further studies of miR-125b in cancer stem cells.Furthermore,MMP9,which plays a role in cancer stem cell invasion,may be a target gene of miR-125b. | Yi Wan Xi-Feng Fei Zhi-Min Wang Dong-Yi Jiang Han-Chun Chen Jian Yang Lei Shi Qiang Huang | 2012 | Chinese Journal of Cancer2012,31,4: | 25 |
| 12 | Zircon SHRIMP U-Pb geochronology of the Neoproterozoic Chengjiang Formation in central Yunnan Province(SW China) and its geological significance显示文摘The Chengjiang Formation is the earliest continental clastic deposit after the Jinning Orogeny in central Yunnan Province,and therefore its accurate depositional age is significant for understanding the formation and evolution of the Neoproterozoic rift basins in southern China.However,hampered by accuracy of the dating technique,the existing age data for the Chengjiang Formation are not very reliable.A large number of magmatic zircons were obtained from the tuff interbed in the lower part of the Chengjiang Formation in Jinyang area and the bottom part of the Chengjiang Formation in Dongchuan area,central Yunnan Province,and high-precision SHRIMP U-Pb dating was carried out on these zircons.The results show that the weighted mean 206 Pb/238 U ages are 797.8±8.2 and 803.1±8.7 Ma respectively.In combination with related geological evidence,it has been demonstrated that the bottom boundary age of the Chengjiang Formation should be 800±5 Ma,whereas the top boundary age could be ca 725 Ma.By synthetically analyzing the latest age data for the relevant strata,it has been confirmed that the Chengjiang Formation should be correlated with the Suxiong Formation and the Kaijianqiao Formation in western Sichuan Province,the Liantuo Formation in the middle and lower Yangtze,the Hongchicun Formation and the Shangshu Formation in northern Zhejiang Province,the Puling Formation in southern Anhui Province,the Luokedong Formation and the Majianqiao Formation in northwestern Jiangxi Province,the Wuqiangxi Formation in northwestern Hunan Province,the Fanzhao Formation and the Qingshuijiang Formation in southeastern Guizhou Province,and the Sanmenjie Formation and the Gongdong Formation in northern Guangxi Province.Sedimentary cycle analysis shows that the sedimentary filling sequence of the Neoproterozoic rift basins in southern China can be divided into four cycles.Among them,Cycle II began at ca.800 Ma,accompanied by intensive tectonic-thermal events.The zircon U-Pb ages from the bottom of the Chengjiang Formation reported in this paper indicate that the Neoproterozoic Kangdian rift subbasin probably started to develop at ca.800 Ma and therefore missed Cycle I of the Neoproterozoic sedimentary filling sequence in southern China. | JIANG XinSheng WANG Jian CUI XiaoZhuang ZHUO JieWen XIONG GuoQing LU JunZe LIU JianHui | 2012 | Science China Earth Sciences2012,55,11: | 25 |
| 13 | Effects of dietary Clostridium butyricum supplementation on growth performance,intestinal development,and immune response of weaned piglets challenged with lipopolysaccharide显示文摘Background: Weanling pigs, with immature immune system and physiological function, usually experience postweaning diarrhea. This study determined the effects of dietary Clostridium butyricum supplementation on growth performance, diarrhea, and immunity of weaned pigs challenged with lipopolysaccharide(LPS).Methods: In Experiment(Exp.) 1,144 weaned piglets were weaned at 21 d and randomly assigned to six groups,with six replicates per group and four pigs per replicate, receiving a control diet(CON) or diet supplemented with antibiotics(AB) or C. butyricum(CB)(0.1%, 0.2%, 0.4%, or 0.8%), respectively. All diets in Exp. 1 were a highly digestible basal diet, with 3,000 mg/kg zinc oxide supplied in the first 2 wk only. In Exp. 2, 180 piglets were weaned at 21 d and randomly assigned to five groups, with six replicates per group and six pigs per replicate, receiving CON, AB, or CB(0.2%, 0.4%, or 0.6%) diets. The digestibility of diets was lower than those in Exp. 1, and did not include zinc oxide. At 36 d of Exp. 2, 12 piglets were selected from each of the CON and 0.4% CB groups, six piglets were intraperitoneally injected with LPS(50 μg/kg body weight) and the other six piglets with normal saline;animals were killed at 4 h after injection to collect blood, intestine, and digesta samples for biochemical analysis.Results: In Exp. 1, CB and AB diets had no effect on growth performance of piglets. In Exp. 2, 0.4% CB decreased feed-gain ratio(P < 0.1), diarrhea score(P < 0.05), and increased duodenal, jejunal, and ileal villus height and jejunal villus height/crypt depth(P < 0.05). The 0.4% CB decreased the plasma tumor necrosis factor(TNF) α(P < 0.05) but increased ileal mucosa IL-10 and TLR2 mRNA expression(P < 0.05). Furthermore, 0.4% CB altered the microbial profile, with Bacillus and Ruminococcaceae UGG-003 at genus level and Lactobacillus casei and Parasutterella secunda at species level were higher than CON in colonic content(P < 0.05).Conclusions: Dietary C. butyricum supplementation had positive effects on growth of weaned piglets with less digestible diets. There was a tendency to reduce the feed-gain ratio, which could reduce feed costs in pig production. Moreover, C. butyricum decreased post-weaning diarrhea by improving the intestinal morphology,intestinal microflora profile, and immune function. | Ling Chen Shuang Li Jie Zheng Wentao Li Xuemei Jiang Xilun Zhao Jian Li Lianqiang Che Yan Lin Shengyu Xu Bin Feng Zhengfeng Fang De Wu | 2018 | Journal of Animal Science and Biotechnology2018,9,4: | 26 |
| 14 | Reversal of hyperglycemia in diabetic rats by portal vein transplantation of islet-like cells generated from bone marrow mesenchymal stem cells显示文摘AIM: To study the capacity of bone marrow mesenchymal stem cells (BM-MSCs) trans-differentiating into islet-like cells and to observe the effect of portal vein transplantation of islet-like cells in the treatment of streptozotocin-induced diabetic rat. METHODS: BM-MSCs were isolated from SD rats and induced to differentiate into islet-like cells under defined conditions. Differentiation was evaluated with electron microscopy, RT-PCR, immunofluorescence and flow cytometry. insulin release after glucose challenge was tested with ELiSA. Then allogeneic islet-like cells were transplanted into diabetic rats via portal vein. Blood glucose levels were monitored and islet hormones were detected in the liver and pancreas of the recipient by immunohistochemistry. RESULTS: BM-MSCs were spheroid adherent monolayers with high CD90, CD29 and very low CD45 expression. Typical islet-like cells clusters were formed after induction. Electron microscopy revealed that secretory granules were densely packed within the cytoplasm of the differentiated cells. The spheroid cells expressed islet related genes and hormones. The insulin-positive cells accounted for 19.8% and mean fluorescence intensity increased by 2.6 fold after induction. The cells secreted a small amount of insulin that was increased 1.5 fold after glucose challenge. After transplantation, islet-like cells could locate in the liver expressing islet hormones and lower the glucose levels of diabetic rats during d 6 to d 20.CONCLUSION: Rat BM-MSCs could be transdifferentiated into islet-like cells in vitro . Portal vein transplantation of islet-like cells could alleviate the hyperglycemia of diabetic rats. | Xiao-Hong Wu Cui-Ping Liu Kuan-Feng Xu Xiao-Dong Mao Jian Zhu Jing-Jing Jiang Dai Cui Mei Zhang Yu Xu Chao Liu | 2007 | World Journal of Gastroenterology2007,13,24: | 23 |

| 19 | A novel gene delivery system targeting cells expressing VEGF receptors显示文摘Two ligand oligopeptides GV1 and GV2 were designed according to the putative binding region of VEGF to its receptors. GV1, GV2 and endosome releasing oligopeptide HA20 were conjugated with poly-L-lysine or protamine and the resulting conjugates could interact with DNA in a noncovalent bond to form a complex. Using pSV2-β-galactosidase as a reporter gene, it has been demonstrated that exogenous gene was transferred into bovine aortic arch-derived endothelial cells (ABAE) andhuman malignant melanoma cell lines (A375) in vitro. In vivo experiments, exogenous gene was transferred into tumor vascular endothelial cells and tumor cells of subcutaneously transplanted human colon cancer LOVO, human malignant melanoma A375 and human hepatoma graft in nude mice. This system could also target gene to intrahepatically transplanted human hepatoma injected via portal vein in nude mice. These results are correlated with theGene delivery system targeting VEGF receptors relevant receptors (flt-1, flk-1/KDR) expression on the targeted cells and tissues. | LI JUN MIN JUN SONG HAN YI HUANG PEI KUN TIAN SHU MIN QU MIN YAO HUI QIU JIANG DA FANG WAN JING CHU LUO CHENG XIAO GU JIAN REN GU( National Labomtory for Oncogenes and Related Genes, Shanghai Cancer Institute, Shanghai 200032,China)(National Laboratory of | 1999 | Cell Research1999,9,1: | 22 |
| 20 | Clinical outcomes of transcatheter selective superior mesenteric artery urokinase infusion therapy vs transjugular intrahepatic portosystemic shunt in patients with cirrhosis and acute portal vein thrombosis显示文摘AIM To compare the outcomes of transcatheter superior mesenteric artery(SMA) urokinase infusion and transjugular intrahepatic portosystemic shunt(TIPS) for acute portal vein thrombosis(PVT) in cirrhosis.METHODS From January 2013 to December 2014, patients with liver cirrhosis and acute symptomatic PVT who met the inclusion criteria were randomly assigned to either an SMA group or a TIPS group. The two groups accepted transcatheter selective SMA urokinase infusion therapyand TIPS, respectively. The total follow-up time was24 mo. The primary outcome measure was the change in portal vein patency status which was evaluated by angio-computed tomography or Doppler ultrasound.Secondary outcomes were rebleeding and hepatic encephalopathy.RESULTS A total of 40 patients were enrolled, with 20 assigned to the SMA group and 20 to the TIPS group. The symptoms of all patients in the two groups improved within 48 h. PVT was improved in 17(85%) patients in the SMA group and 14(70%) patients in the TIPS group. The main portal vein(MPV) thrombosis was significantly reduced in both groups(P < 0.001), and there was no significant difference between them(P= 0.304). In the SMA group, superior mesenteric vein(SMV) thrombosis and splenic vein(SV) thrombosis were significantly reduced(P = 0.048 and P = 0.02),which did not occur in the TIPS group. At 6-, 12-,and 24-mo follow-up, in the SMA group and the TIPS group, the cumulative rates free of the first episode of rebleeding were 80%, 65%, and 45% vs 90%, 80%,and 60%, respectively(P = 0.320); the cumulative rates free of the first episode of hepatic encephalopathy were 85%, 80%, and 65% vs 50%, 40%, and 35%,respectively(P = 0.022).CONCLUSION Transcatheter selective SMA urokinase infusion and TIPS are safe and effective for acute symptomatic PVT in cirrhosis. | Ting-Ting Jiang Xiao-Ping Luo Jian-Ming Sun Jian Gao | 2017 | World Journal of Gastroenterology2017,23,41: | 22 |
