1Inhibiting effect of antisense oligonucleotides phosphorthioate on gene expression of TIMP-1 in rat liver fibrosis显示文摘AIM To observe the inhibition of antisenseoligonucleotides (asON) phosphorthioate to thetissue inhibitors metalloproteinase-1 (TIMP-1)gene and protein expression in the liver tissue ofimmunologically induced hepatic fibrosis rats.The possibility of reversing hepatic fibrosisthrough gene therapy was observed.METHODS Human serum albumin (HSA) wasused to attack rats, as hepatic fibrosis model, inwhich asONs were used to block the gene andprotein expressing TIMP-1. According to theanalysis of modulator, structure protein, codingseries of TIMP-1 genome, we designed fourdifferent asONs. These asONs were injected intothe hepatic fibrosis models through coccygealvein. The results was observed by RT-PCR formeasuring TIMP-1 mRNA expression,immunohistochemistry and in situ hybridizationfor collagen Ⅰ, Ⅲ, special staining of collagenfiber, and electron microscopic examination.RESULTS Hepatic fibrosis could last within 363days in our modified model. The expressinglevel of TIMP-1 was high during hepatic fibrosisprocess. It has been proved by theimmunohistochemical and the electronmicroscopic examination that the asONphosphorthioate of TIMP-1 could exactly expressin vivo. The effect of colchicine wasdemonstrated to inhibit the expressing level ofmRNA and the content of collagen Ⅰ, Ⅲ in theliver of experimental hepatic fibrosis rats.However, the electron microscopy research andthe pathologic grading of hepatic fibrosisshowed that there was no significant differencebetween the treatment group and the modelgroup (P>0.05).CONCLUSION The experimental rat model ofhepatic fibrosis is one of the preferable modelsto estimate the curative effect of anti-hepaticfibrosis drugs. The asON phosphorthioate ofTIMP-1 could block the gene and proteinexpression of TIMP-1 in the liver of experimentalhepatic fibrosis rats at the mRNA level. It ispossible to reverse hepatic fibrosis, and it isexpected to study a new drug of anti-hepaticfibrosis on the genetic level. Colchicine has verylimited therapeutic effect on hepatic fibrosis,furthermore, its toxicity and side effects areobvious.Qing He Nie Yong Qian Cheng Yu Mei Xie Yong Xing Zhou Yi Zhan Cao The Center of Infectious Disease Diagnosis and Treatment of PLA,Tangdu Hospital,Forth Military Medical University,Xi’an 710038,Shaanxi Province,ChinaDr,Qing He Nie graduated from Qinghai Medical College as a doctor in 1983,got master degree at Beijing 302 Army Hospital in 1993,got doctor degree at the Third Military Medical University in 1998,engaged in postdoctoral research at the Fourth Military Medical University from 1998 to 2000,now an associate professor,specialized in clinical and experimental research of infectious diseases,had more than 90 papers published,coauthor of ten books,first author of one book. 2001World Journal of Gastroenterology2001,7,3:73

3Carbon isotope composition of the Lower Triassic marine carbonates, Lower Yangtze Region, South China显示文摘Studies on three Lower Triassic sections located on the shallow water platform, the deep water slope and in the deep water basin in the Lower Yangtze Region, South China, show the similar trend of carbon isotope evolution. Biostratigraphic correlations among the Lower Triassic sections on the basis of standard conodont zones indicate that three negative shifts occurred in the Griesbachian, the Smithian and the late Spathian stages respectively, and one distinctly positive shift occurred in the early Spathian stage. Trend of carbon isotope evolution of the Lower Triassic reflects some significant changes in the global carbon cycle. Moreover, δ 13C background values are intensively controlled by palaeogeographic environment. In general, δ 13C values from deep-water slope carbonates are lighter than those from carbonate platform and heavier than those from deep-water basin carbonates. The positive carbon isotope excursion may be induced by a significant amount of organic carbon burial in marine sediments and increase in primary productivity. The large negative carbon isotope excursions during the Early Triassic in Lower Yangtze Region are interpreted to relate to volcano eruptions based on tuffaceous claystone interlayers observed near the Permian-Triassic boundary, the Induan- Olenekian boundary and the Lower Triassic-Middle Triassic boundary.ZUO Jingxun1,2, TONG Jinnan3, QIU Haiou4 & ZHAO Laishi3 1.

4Early J_2 basalts in SE China:Incipience of large-scale late Mesozoic magmatism显示文摘Magmatism in SE China was dormant during 204―180 Ma, but was reactivated in 180― 170 Ma (early J2), and then became more and more intensive towards the end of early Cretaceous. The small-scale early J2 magmatism is the incipience to long-term and large-scale magmatism in this region. A near east-west (EW) trend volcanic belt was distributed across south Hunan, south Jiangxi and southwest Fujian was formed during early J2 time. Along this belt from the inland toward the coast, the lithology of basalts changes from alkali into tholeiite, and the amount of erupted volcanic rocks and the proportions of rhyolites coexisting with the basalts increase. On the basis of geochemical char- acteristics of these basalts, we infer that the melting degree of source rocks and the extent of frac- tional crystallization and crustal contamination all increased whereas the depth of mantle source de- creased from the inland to the coast, which led to the variations of geological characteristics of the volcanic belt. In early J2, the western spreading Pacific plate began to subduct underneath SE China continental block, reactivating near EW trend deep fault that was originally formed during the Indos- inian event. The stress of the western spreading Pacific plate and the extent of asthenosphere up- welling increased from the inland to the coast, which is consistent with the generation and evolution of early J2 basalts.XIE Xin1, XU Xisheng1, ZOU Haibo2, JIANG Shaoyong1, ZHANG Ming3 & QIU Jiansheng1 1.

5Antihepatoma effect of alpha-fetoprotein antisense phosphorothioate oligodeoxyribonucleotides in vitro and in mice显示文摘AIM To evaluate antihepatoma effect ofantisense phosphorothioate oligodeo-xyribonucleotides (S-ODNs) targeted to alpha-fetoprotein (AFP) genes in vitro and in nudemice.METHODS AFP gene expression was examinedby immunocytochemical method or enzyme-linked immunosorbent assay. Effect of S-ODNson SMMC-7721 human hepatoma cell growth invitro was determined using microculturetetrazolium assay. In vivo antitumor activitiesof S-ODNs were monitored by measuring tumorweight differences in treated and control micebearing SMMC-7721 xenografts. Induction of cellapoptosis was evaluated by fluorescence-activated cell sorter (FACS) analysis.RESULTS Antisense S-ODN treatment led toreduced AFP gene expression. Specificantisense S-ODNs, but not control S-ODNs,inhibited the growth of heaptoma cells in vitro.In vivo. only antisense S-ODNs exhibitedobvious antitumor activities. FACS analysisrevealed that the growth inhibition by antisenseS. ODNs was associated with their cell apoptosisinduction.CONCLUSION Antisense S-ODNs targeted toAFP genes inhibit the growth of human hepatomacells and solid hepatoma, which is related totheir cell apoptosis induction.Xing Wang Wang~1 Jin Hui Yuan~1 Ru Gang Zhang~1 Li Xia Guo~1 Yong Xie~2 Hong Xie~1 ~1Department of Biotherapy,Shanghai Institute of Cell Biology,Chinese Academy of Sciences,Shanghai 200031,China ~2Department of Biology,Hong Kong University of Science and Technology,ChinaDr.Xing Wang Wang earned Ph.D.from Shanghai Institute of Materia Medical,Chinese Academy of Sciences in 1997.Now a professor at Shanghai Institute of Cell Biology,Chinese Academy of Sciences. 2001World Journal of Gastroenterology2001,7,3:21
6Quantum secret sharing between multiparty and multiparty with Bell states and Bell measurements显示文摘We present a quantum secret sharing scheme between multiparty (m members in Group 1) and multiparty (n members in Group 2), and analyze its security. This scheme takes EPR pairs in Bell states as quantum resources. In order to obtain the shared key, all members only need to perform Bell measurements, rather than perform any local unitary operation. The total efficiency in this scheme approaches 100% as the classical information exchanged is not necessary except for the eavesdropping checks.SHI RunHua 1,2* , HUANG LiuSheng 1,3 , YANG Wei 1,3 & ZHONG Hong 2 1 National High Performance Computing Center at Hefei, Department of Computer Science and Technology, University of Science and Technology of China, Hefei, 230027, China 2 School of Computer Science and Technology, Anhui University, Hefei 230039, China 3 Suzhou Institute for Advanced Study, USTC, Suzhou 215123, China 2010Science China(Physics,Mechanics & Astronomy)2010,53,12:17

8Immunization with chlamydial plasmid protein pORF5 DNA vaccine induces protective immunity against genital chlamydial infection in mice显示文摘To validate the immune protective efficacy of pORF5 DNA vaccine and to analyze potential mechanisms related to this protection. In this study, pORF5 DNA vaccine was constructed and evaluated for its protective immunity in a mouse model of genital chlamydial infection. Groups of BALB/c mice were immunized intranasally with pORF5 DNA vaccine. Humoral and cell mediated immune responses were evaluated. The clearance ability of chlamydial challenge from the genital tract and the chlamy- dia-induced upper genital tract gross pathology and histopathological characterization were also de- tected. The results showed that the total and the IgG2a anti-pORF5 antibody levels in serum were sig- nificantly elevated after pcDNA3.1-pORF5 vaccination, as were the total antibody and IgA levels in vaginal fluids. pcDNA3.1-pORF5 induced a significantly high level of Th1 response as measured by robust gamma interferon (IFN-γ). Minimal IL-4 was produced by immune T cells in response to the re-stimulation with pORF5 protein or the inactive elementary body in vitro. pcDNA3.1-pORF5-vacci- nated mice displayed significantly reduced bacterial shedding upon a chlamydial challenge and an accelerated resolution of infection. 100% of pcDNA3.1-pORF5 vaccinated mice successfully resolved the infection by day 24. pcDNA3.1-pORF5-immunized mice also exhibited protection against patho- logical consequences of chlamydial infection. The stimulated index was significantly higher than that of mice immunized with pcDNA3.1 and PBS (P<0.05). Together, these results demonstrated that immu- nization with pORF5 DNA vaccine is a promising approach for eliciting a protective immunity against a genital chlamydial challenge.LI ZhongYu1,2, WANG ShiPing1, Wu YiMou2, ZHONG GuangMing3 & CHEN Ding3 1 Xiangya School of Medicine, Central South University, Changsha 410078, China 2 Department of Microbiology and Immunology, University of South China, Hengyang 421001, China 3 University of Texas Health Science Center at San Antonio, TX 78229, USA 2008Science China(Life Sciences)2008,51,11:16

10Clinical features of nonalcoholic fatty liver disease-associated hepatocellular carcinoma显示文摘BACKGROUND: Nonalcoholic fatty liver disease (NAFLD), especially nonalcoholic steatohepatitis, is a recognized risk factor for hepatocellular carcinoma (HCC). However, detailed analysis of the clinical features in patients with NAFLD and their association with HCC is lacking. This study aimed to update the clinical features of patients with NAFLD-associated HCC. DATA SOURCES: The clinical data of patients with NAFLD- associated HCC from 25 studies published between 1990 and 2010 in the Pubmed database were comprehensively reviewed. RESULTS: In a total of 169 patients with NAFLD-associated HCC, 72.8% were male. The median age at abnormal liver function tests and diagnosis of NAFLD and HCC was 60, 64 and 67 years, respectively. Most patients were obese (75%) and diabetic (59.8%), 32.3% had dyslipidemia, and 53% had hypertension. Nearly all patients (98.6%, 71/72) were complicated with at least one metabolic disorder. The majority (76%) of the HCC patients had a solitary tumor nodule, with the tumor size ranging from 0.8 to 20 cm in diameter (mean 3.4 cm). Most (61.1%) of the patients had moderately-differentiated HCC. In 40.2% of the patients, HCC occurred in the absence of cirrhosis. Among 130 patients, 57.7% underwent hepatectomy and 14.6% received liver transplantation. The mean follow-up of the treated patients for 25 months showed that 32.4% (24/74) died and 18.8% (9/48) had recurrence. CONCLUSIONS: Patients with NAFLD-associated HCC are usually accompanied with metabolic disorders. Regular surveillance in patients with NAFLD for HCC is necessary, especially for elderly men with metabolic syndrome.Xiao-Yan Duan, Liang Qiao and Jian-Gao Fan Department of Gastroenterology, Xinhua Hospital, Shanghai Jiaotong University School of Medicine, Shanghai 200092, China Storr Liver Unit at the Westmead Millennium Institute, the University of Sydney at Westmead Hospital, Westmead, NSW 2145, Australia 2012Hepatobiliary & Pancreatic Diseases International2012,11,1:16

14Restudies on Body Surface of Dung Beetle and Application of Its Bionics Flexible Technique显示文摘A scanning electron microscope was used to observe the structures of the setae on the surface of a dung beetle Copris ochus, Motschulsky. There are lots of setae on the body surface, especially on the ventral part surface and lateral to the legs which are different in size, arrangement and shape. These setae have different lengths and many thorns on the whole seta. The top ends of these setae stand up without furcations which direct uprightly towards the surface of the touched soil. By the method of removing these setae, getting the insect weight before and after digging into the dung we affirm farther that the setae on the beetle body surface form the anti-stick and non-adherent gentle interface. The soil machines and components made by imitating the gentle body surface of beetles have favorable non-adherent results.Jiurong Sun 1, Jianqiao Li 2, Hong Cheng 1, Zhendong Dai 3, Luquan Ren 2 1.College of Life Sciences, Peking University, Beijing, 100871,P.R.

15Syntheses of amphiphilic biodegradable copolymers of poly(ethyl ethylene phosphate) and poly(3-hydroxybutyrate) for drug delivery显示文摘Biodegradable and amphiphilic triblock copolymers poly(ethyl ethylene phosphate)-poly(3-hydroxybutyrate)-poly(ethyl ethylene phosphate) (PEEP-b-PHB-b-PEEP) have been successfully synthesized through ring-opening polymerization. The structures are confirmed by gel permeation chromatography and NMR analyses. Crystallization investigated by X-ray diffraction reveals that the block copolymer with higher content of poly(ethyl ethylene phosphate) (PEEP) is more amorphous, showing decreased crystallizability. The obtained copolymers self-assemble into biodegradable nanoparticles with a coreshell micellar structure in aqueous solution, verified by the probe-based fluorescence measurements and transmission electronic microscopy (TEM) observation. The hydrophobic poly(3-hydroxybutyrate) (PHB) block serves as the core of the micelles and the micelles are stabilized by the hydrophilic PEEP block. The size and size distribution are related to the compositions of the copolymers. Paclitaxel (PTX) has been encapsulated into the micelles as a model drug and a sustained drug release from the micelles is observed. MTT assay also demonstrates that the block copolymers are biocompatible, rendering these copolymers attractive for drug delivery.CHENG Jing1 & WANG Jun2 1 Department of Polymer Science and Engineering, University of Science and Technology of China, Hefei 230026, China 2 Hefei National Laboratory for Physical Sciences at Microscale, School of Life Sciences, University of Science and Technology of China, Hefei 230027, China 2009Science China Chemistry2009,52,7:10
16Current progress in epigenetic research for hepato-carcinomagenesis显示文摘Hepatocellular carcinoma is the main type of primary liver cancer,and also one of the most malignant tumors.At present,the pathogenesis mechanisms of liver cancer are not entirely clear.It has been shown that inactivation of tumor suppressor genes and activation of oncogenes play a significant role in carcinogenesis,caused by the genetic and epigenetic aberrance.In the past,people generally thought that genetic mutation is a key event of tumor pathogenesis,and somatic mutation of tumor suppressor genes is in particular closely associated with oncogenesis.With deeper understanding of tumors in recent years,increasing evidence has shown that epigenetic silencing of those genes,as a result of aberrant hypermethylation of CpG islands in promoters and histone modification,is essential to carcinogenesis and metastasis.The term epigenetics refers to heritable changes in gene expression caused by regulation mechanisms,other than changes in the underlying DNA sequence.Specific epigenetic processes include DNA methylation,genome imprinting,chromotin remodeling,histone modification and microRNA regulations.This paper reviews recent epigenetics research progress in the hepatocellular carcinoma study,and tries to depict the relationships between hepatocellular carcinomagenesis and DNA methylation as well as microRNA regulation.HUANG Jian National Human Genome Research Center at Shanghai-Ministry of Science and Technology to build a healthy and disease Ge-nomics Laboratory,Shanghai 201203,China 2009Science China(Life Sciences)2009,52,1:9
