2Dynamic changes of typeⅠ,Ⅲand N collagen synthesis and distribution of collagen-producing cells in carbon tetrachloride-induced rat liver fibrosis显示文摘AIM To find out the relationship between the gene transcription of different types ofprocollagen and the deposition of the relevant collagens in the liver tissue and to confirm the types of collagen producing cells in liverfibrogenesis.METHODS Dynamic changes of the expression of α1(Ⅰ ), α1 (Ⅲ ) and α1 (Ⅳ) procollagen mRNAand relevant collagens and the distribution ofcollagen producing cells during liver fibrogenesis of rat induced by CCl4 (20 weeks)were investigated with Northern blot analysis,in situ hybridization and immunohistochemicaltechniques.RESULTS The increased expression of α1 (Ⅲ)procollagen mRNA by Northern blot analysis was the most predominant one among the threemRNAs during fibrogenesis. However, theenhanced expression of al (Ⅳ) procollagenmRNA occurred very early while the expressionof α1 (Ⅰ) mRNA was not enhanced much until themiddle stage of the exPeriment. D6smin (Dm)positive hepatic stellate cells (HSCs) and fewmyofibroblasts (MFs) in and around the necrotic areas expressed α1 (Ⅰ), α1 (Ⅲ) and α1 (Ⅳ)procollagen mRNA signals detected by in situhybridization at the early stage of theexperiment. All the three procollagen mRNAsignals thereafter mainly localized in fibroblasts (Fbs) and MFs in fibrotic septa during the middle and late stages of fibrosis, which distributedparallel to the corresponding collagens detected by immunohistochemical study. ln addition, the endothelial cells of sinusoids and the small blood vessels within the septa also showed α1(Ⅳ) procollagen mRNA and type Ⅳ collagen expressionCONCLUSION It is considered that 'HSC-MF-Fb' effect cell system is the major cellularsource of collagen production in liver fibrosis, in which HSCs are collagen producing precursor cells in the early liver fibrogenesis, thereafter the synthesis of type Ⅰ, Ⅲ and Ⅳ collagens (Col Ⅰ, Col Ⅲ and Col Ⅳ) mainly derives fromMFs and Fbs, which play a very important role in the progress of liver fibrosis. The endothelialcells along sinusoids, as another source of Col Ⅳ production, might participate in the capillization of liver sinusoids.DU Wei-Dong ZHANG Yue-E ZHAl Wei-Rong and ZHOU Xiao-Mei(Department of Pathology, Shanghai Medical University, Shanghai200032, China)(National Laboratory for Oncogenes and Related Genes, ShanghaiCencer Institute)See invited commentary on page 388 1999World Journal of Gastroenterology1999,5,5:47
3流动儿童心理韧性对其抑郁、孤独的影响显示文摘本研究采用心理韧性和抑郁、孤独量表作为研究工具,对685名流动儿童心理韧性特点及对抑郁、孤独影响进行研究。结果发现:男生、转学次数多、打工子弟学校、来北京时间较少、家庭收入低的流动儿童,他们抑郁、孤独感更高;流动儿童心理韧性比其个人、家庭、学校因素对抑郁和孤独的预测能力更强,在控制了这些因素之后,心理韧性仍然能够显著地预测其抑郁和孤独感。王中金 Gening Jin 蔺秀云 2014中国特殊教育2014,,4:36
4Dissection of genetic overlap of salt tolerance QTLs at the seedling and tillering stages using backcross introgression lines in rice显示文摘QTLs for salt-tolerance(ST)related traits at the seedling and tillering stages were identified using 99 BC2F8 introgression lines(IL)derived from a cross between IR64(indica)as a recurrent parent and Binam(japonica)from Iran as the donor parent.Thirteen QTLs affecting survival days of seedlings(SDS), score of salt toxicity of leaves(SST),shoot K + concentration(SKC)and shoot Na + concentration(SNC) at the seedling stage and 22 QTLs underlying fresh weight of shoots(FW),tiller number per plant(TN) and plant height(PH)at the tillering stage were identified.Most QTLs detected at the tillering stage showed obvious differential expression to salt stress and were classified into three types based on their differential behaviors.Type I included 11 QTLs which were expressed only under the non-stress condition.Type II included five QTLs expressed in the control and the salt stress conditions,and three of them(QPh5,QPh8 and QTn9)had similar quantity and the same direction of gene effect,suggesting their expression was less influenced by salt stress.Type III included six QTLs which were detectable only under salt stress,suggesting that these QTLs were apparently induced by the stress.Thirteen QTLs affecting trait difference or trait stability of ILs between the stress and non-stress conditions were identified and the Binam alleles at all loci except QPh4,QTn2 and QFw2a decreased trait difference.The three QTLs less influenced by the stress and 13 QTLs affecting trait stability were considered as ST QTLs which contributed to ST.Comparing the distribution of QTLs detected at the seedling and tillering stages,most(69%)of them were genetically independent.Only four were the same or adjacent regions on chromosomes 1,2,8 and 11 harboring ST QTLs detected at the two stages,suggesting that partial genetic overlap of ST across the two stages occurs.It is likely,therefore,to develop ST rice variety for both stages by pyramiding of ST QTLs of different stages or selection against the overlapping QTLs between the two stages via marker-assisted selection(MAS).ZANG JinPing 1 ,SUN Yong 1 ,WANG Yun 1 ,YANG Jing 1 ,LI Fang 1 ,ZHOU YongLi 1 ,ZHU LingHua 1 , Reys JESSICA2,Fotokian MOHAMMADHOSEIN 2,XU JianLong 1&LI ZhiKang 1,2 1Institute of Crop Sciences/National Key Facility for Crop Gene Resources&Genetic Improvement,Chinese Academy of Agricul- tural Sciences,Beijing 100081,China 2International Rice Research Institute,DAPO Box 7777,Metro Manila,Philippines 2008Science China(Life Sciences)2008,51,7:32
5A 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 1999Cell Research1999,9,1:22

14The tumor-selective over-expression of the human Hsp 70 gene is attributed to the aberrant controls at both initiation and elongation levels of transcription显示文摘The tumor selective over-expression of the human Hsp70 gene has been well documented in human tumors,linked to the poor prognosis,being refractory to chemo-and radio-therapies as well as the advanced stage of tumorous lesions in particular.However,both the nature and details of aberrations in the control of the Hsp70 expression in tumor remain enigmatic.By comparing various upstream segments of the Hsp70 gene for each''s ability to drive the luciferase reporter genes in the context of the tumor cell lines varying in their p53 status and an immortal normal liver cell line,we demonstrated in a great detail the defects in the control mechanisms at the both initiation and elongation levels of transcription being instrumental to the tumor selective profile of its expression.Our data should not only offer new insights into our understanding of the tumor specific over-expression of the human Hsp70 gene,but also paved the way for the rational utilization of the tumor selective mechanism with the Hsp70 at the central stage fortargeting the therapeutic gene expression to human tumors.LING CAI, JING DE ZHU,The State-key Laboratory for Oncogenes and Related Genes, Shanghai Cancer Institute, LN 25/2200, Xie-tu Road, Shanghai 200032, China 2003Cell Research2003,13,2:13

17Detection of soluble TRAIL in HBV infected patients and its clinical implications显示文摘AIM: To detect the expression of soluble TRAIL (TNF-related apoptosis inducing ligand, TRAIL) in the peripheral blood of HBV infected patients and try to elucidate whether the expression level of sTRAIL have any correlativity with the clinical staging, the expression level of HBV markers and the degree of liver damage.METHODS: 52 cases of HBV infected patients were investigated, induding 8 HBV carriers, 30 chronic hepatitis B, 11 drrhotics and 3 HBV infection related hepatocellular carcinoma. Expression of soluble TRAIL and markers of the hepatitis B were mearsured by enzyme-linked immunosorbent assay.RESULTS: The expression level of sTRAIL in the peripheral blood of the HBV infected patients was significantly higher than that of healthy controls (1378.35±540.23 pg/ml vs 613.75±175.80 pg/ml, P<0.001). In the group of chronic hepatitis, the expression level of sTRAIL was coincident with the status of the disease and was significantly correlated with the level of ALT. In the group of cirrhosis and liver cancer, its expression level was significantly higher than that of the healthy persons and HBV carriers, but lower than that of the hepatitis B patients; meanwhile, the expression of siRAIL did not have any correlativity with the functional indexes of the liver. CONCLUSION: The soluble TRAIL in the HBV infected people may participate in the liver damage. Our results indicated that the expression level of soluble TRAIL may reflect the ravage of liver caused by host immune reaction to a certain degree.Li-Hui Han Wen-Sheng Sun Chun-Hong Ma Li-Ning Zhang Su-Xia Liu Qiu Zhang Li-Fen Gao,Institute of Immunology,Medical College of Shandong University,Jinan 250012,Shandong Province,China You-Hai Chen,Institute for Human Gene Therapy,University of Pennsylvania,Philadelphia PA 19104,USA 2002World Journal of Gastroenterology2002,8,6:12

19Proteomic analysis of mitochondria reveals a metabolic switch from fatty acid oxidation to glycolysis in the failing heart显示文摘This work characterizes the mitochondrial proteomic profile in the failing heart and elucidates the molecular basis of mitochondria in heart failure. Heart failure was induced in rats by myocardial infarction, and mitochondria were isolated from hearts by differential centrifugation. Using two-dimensional gel electrophoresis and matrix-assisted laser desorption/ionization-time of flight mass spectrometry, a system biology approach was employed to investigate differences in mitochondrial proteins between normal and failing hearts. Mass spectrometry identified 27 proteins differentially expressed that involved in energy metabolism. Among those, the up-regulated proteins included tricarboxylic acid cycle enzymes and pyruvate dehydrogenase complex subunits while the down-regulated proteins were involved in fatty acid oxidation and the OXPHOS complex. These results suggest a substantial metabolic switch from free fatty acid oxidation to glycolysis in heart failure and provide molecular evidence for alterations in the structural and functional parameters of mitochondria that may contribute to cardiac dysfunction during ischemic injury.WANG Jun1,2, BAI Ling1,2, LI Jing3, SUN ChaoFeng1,2, ZHAO Jin1, CUI ChangCong1,2, HAN Ke1,2, LIU Yu1,2, ZHUO XiaoZhen1,2, WANG TingZhong1,2, LIU Ping1,2, FAN FenLing1,2, GUAN YouFei3 & MA AiQun1,2 1 Department of Cardiology, First affiliated hospital of medical college of Xi’an Jiaotong University, Xi’an 710061, China 2 Ion Channel Disease Laboratory, Key Laboratory of Environment and Genes Related to Diseases of Education Ministry, Xi’an 710061, China 3 Department of Physiology and Pathophysiology Key Laboratory of Molecular Cardiovascular Sciences of the Ministry of Education, Peking University Health Science Center, Beijing 100083, China 2009Science China(Life Sciences)2009,52,11:10
20Selection of candidates for surgery as local therapy among early-stage small cell lung cancer patients: a population-based analysis显示文摘Background:Surgery and radiotherapy are considered local therapies for small cell lung cancer(SCLC).The present study aimed to select candidates for surgery as local therapy among patients with stage I or II SCLC,based on the eighth edition of the TNM classification for lung cancer.Methods:Patients diagnosed with SCLC between 2004 and 2013 were selected from the Surveillance,Epidemiology,And End Results database.The TNM stage of SCLC in these patients was re-classified according to the eighth edition of the TNM classification for lung cancer.Patients with stage I or II SCLC were included in the present study.Overall survival(OS)and lung cancer-specific survival(LCSS)were separately compared in the different TNM stages between patients who received surgery and radiotherapy as local therapy.Multivariate analysis was applied to evaluate multi-ple factors associated with survival.Results:Among the 2129 patients included in the present study,387(18.2%)received surgery,1032(48.5%)under-went radiotherapy as local therapy,154(7.2%)underwent surgery and radiotherapy,and 556(26.1%)did not undergo either surgery or radiotherapy.Among patients with T1-2N0(tumor size≤50 mm without positive lymph nodes)dis-ease,patients who underwent surgery had higher 5-year OS and LCSS rates than patients who received radiotherapy(T1N0:46.0%vs.23.8%,P<0.001,and 58.4%vs.36.4%,P<0.001,respectively;T2N0:42.6%vs.24.7%,P=0.004,and 48.8%vs.31.3%,P=0.011,respectively).Multivariate analysis results revealed that surgery was associated with low risk of death.However,among T3N0 or T1-2N1(stage IIB)SCLC patients,patients who underwent surgery did not have higher 5-year OS and LCSS rates than patients who received radiotherapy(T3N0:16.2%vs.26.5%,P=0.085,and 28.7%vs.30.9%,P=0.372,respectively;T1-2N1:20.3%vs.29.0%,P=0.146,and 25.6%vs.35.5%,P=0.064,respectively).Conclusions:Based on the assumption that the overwhelming majority of stage I or II SCLC patients who underwent surgery or radiotherapy also received certain types of systemic therapy,only patients with T1-2N0 SCLC may benefit from surgery as local therapy.Patients with T3N0 or T1-2N1 SCLC may consider radiotherapy as local therapy.Kaiqi Jin Kaixuan Zhang Feng Zhou Jie Dai Peng Zhang Gening Jiang 2018Cancer Communications2018,38,1:9
