| 10 | Hepatocellular carcinoma: Review of disease and tumor biomarkers显示文摘Hepatocellular carcinoma(HCC) is a common malignancy and now the second commonest global cause of cancer death. HCC tumorigenesis is relatively silent and patients experience late symptomatic presentation. As the option for curative treatments is limited to early stage cancers, diagnosis in non-symptomatic individuals is crucial. International guidelines advise regular surveillance of high-risk populations but the current tools lack sufficient sensitivity for early stage tumors on the background of a cirrhotic nodular liver. A number of novel biomarkers have now been suggested in the literature, which may reinforce the current surveillance methods. In addition, recent metabonomic and proteomic discoveries have established specific metabolite expressions in HCC, according to Warburg's phenomenon of altered energy metabolism. With clinical validation, a simple and non-invasive test from the serum or urine may be performed to diagnose HCC, particularly benefiting low resource regions where the burden of HCC is highest. | Jin Un Kim Mohamed I F Shariff Mary M E Crossey Maria Gomez-Romero Elaine Holmes I Jane Cox Haddy K S Fye Ramou Njie Simon D Taylor-Robinson | 2016 | World Journal of Hepatology2016，8，10： | 13 |
| 11 | Liver expression of steroid hormones and Apolipoprotein D receptors in hepatocellular carcinoma显示文摘AIM: To evaluate the tissular expression of Androgen (A), Estrogen (E) and Progesterone (Pg) receptors, and Apolipoprotein D (ApoD), in liver tumors from resected hepatocellular carcinoma (HCC) cases in order to assess their possible relationship to prognosis. METHODS: We performed an immunohistochemical study using tissue microarrays (containing more than 260 cancer specimens, from 31 HCC patients and controls) to determine the presence of specif ic antibodies against AR, ER, PgR and ApoD, correlating their findings with several clinico-pathological and biological variables. The staining results were categorized using a semi-quantitive score based on their intensity, and the percentage of immunostained cells was measured. RESULTS: A total of 21 liver tumors (67.7%) were positive for AR; 16 (51.6%) for ER; 26 (83.9%) for PgR and 12 (38.7%) stained for ApoD. We have found a wide variability in the immunostaining score values for each protein, with a median (range) of 11.5 (11.5-229.5) for AR; 11.1 (8.5-65) for ER; 14.2 (4-61) for PgR; and 37.7 (13.8-81.1) for ApoD. A history of heavy ethanol consumption, correlated positively with AR and PgR and negatively with ER status. HCV chronic infection also correlated positively with AR and PgR status. However, the presence of ApoD immunostaining did not correlate with any of these variables. Tumors with a positive immuno-staining for PgR showed a better prognosis. CONCLUSION: Our results indicate a moderate clinical value of the steroid receptor status in HCC, emphasizing the need to perform further studies in order to evaluate the possible role of new hormonal-based therapies. | FJ Vizoso M Rodriguez A Altadill ML González-Diéguez A Linares LO González S Junquera F Fresno-Forcelledo MD Corte L Rodrigo | 2007 | World Journal of Gastroenterology2007，13，23： | 11 |

| 13 | Polymorphisms of MTHFD,plasma homocysteine levels, and risk of gastric cancer in ahigh-risk Chinese population显示文摘Purpose:Accumulative evidence suggests that folate has a protective effect on gastric cancer. The methylenetetrahyd-rofolate dlehydrogenase(MTHFD) plays an important role in folate and homocysteine metabolisms, and polymorphisms of MTHFD may result in disturbance of the folate-mediated homocysteine pathway. The aim of this study is to test the hypothesis that genetic variants of MTHFD and plasma homocysteine levels are associated with risk of gastric cancer and modulated by genotypes of methylenetetrahydrofolate reductase(MTHFR). Experimental Design: We genotyped G1958A and T401C in MTHFD and C677T in MTHFR and detected total plasma homocysteine(tHcy) levels in a case-control study of 589 gastric cancer cases and 635 cancer-free controls in a high-risk Chinese population. Results:The variant genotypes of MTHFD 1958AA and 401CC were associated with a significantly increased risk of gastric canceradjusted odds ratio(OR), 2.05; 95% confidence interval(95% CI),1.34-3.13 for 1958AA; adjusted OR,1.43; 95% CI,1.14-1.80 for 401CC compared with 1958GG/GA and 401TT/TC genotypes, respectively. Both of the effects were more evident in the subjects carrying MTHFR 677CT/TT genotypes. The average tHcy level was significantly higher in gastric cancer cases than in controls(P < 0.01), and the upper quartile of tHcy (> 13.6 mu mol/L) was associated with an 82% significantly increased risk of gastric cancer, compared with the lowest quartile of tHcy(<= 8.0 pmol/L;adjusted OR,1.82; 95% CI,1.20-2.75). Conclusions:The strong associations between MTHFD variants and the plasma tHcy levels and gastric cancer risk suggest, for the first time, a possible gene-environment interaction between genetic variants of folate-metabolizing genes and high tHcy levels in gastric carcinogenesis. | Wang, L.

| 16 | Contribution of TLR signaling to the pathogenesis of colitisassociated cancer in inflammatory bowel disease显示文摘In the intestine a balance between proinflammatory and repair signals of the immune system is essential for the maintenance of intestinal homeostasis. The innate immunity ensures a primary host response to microbial invasion, which induces an inflammatory process to localize the infection and prevent systemic dissemination of pathogens. The key elements of this process are the germline encoded pattern recognition receptors inclu-ding Toll-like receptors(TLRs). If pathogens cannot be eliminated, they may elicit chronic inflammation, which may be partly mediated via TLRs. Additionally, chronic inflammation has long been suggested to trigger tissue tumorous transformation. Inflammation, the seventh hallmark of cancer, may affect all phases of tumor development, and evade the immune system. Inflammation acts as a cellular stressor and may trigger DNA damage or genetic instability. Furthermore, chronic inflammation can provoke genetic mutations and epigenetic mechanisms that promote malignant cell transformation. Colorectal cancers in inflammatory bowel disease patients are considered typical examples of inflammation-related cancers. Although data regarding the role of TLRs in the pathomechanism of cancer-as-sociated colitis are rather conflicting, functionally these molecules can be classified as 'largely antitumorigenic' and 'largely pro-tumorigenic' with the caveat that the underlying signaling pathways are mainly context(i.e., organ-, tissue-, cell-) and ligand-dependent. | Ferenc Sipos István Fri Miklós Constantinovits Zsolt Tulassay Gyrgyi Mzes | 2014 | World Journal of Gastroenterology2014，20，36： | 9 |
| 17 | 强脉冲离子注入中的脉冲能量效应研究显示文摘在脉冲离子束流密度为15-120A/cm2、脉宽为50-150ns、加速电压为150-260kV范围内,在1×104cm-2的低注量水平上,研究了高功率Cn++H+混合离子束注入45号钢样品的强脉冲能量效应.摩擦磨损和微观硬度测量以及SEM和X射线衍射分析表明,上述低注量强脉冲离子束注入可以改变材料表面的微观结构和力学特性,而且强烈依赖于单个脉冲离子束的功率密度和能量密度,在相同离子注量条件下,普通C++H+离子注入对45号钢样品表面微硬度和摩擦系数未见明显影响.直接证明了强脉冲能量效应在离子注入中是相对独立于注入元素掺杂效应的又一可利用的重要效应.基于一维导热模型,讨论了强脉冲能量效应以及脉冲离子束功率密度对离子束材料表面改性的作用。 | 赵渭江 颜莎 乐小云 韩宝玺 薛建明 王宇钢 Remmev G E Opekounov M S Isakov I F Grushin II | 2000 | 核技术2000，23，10： | 8 |
| 18 | Ultrafine Grained HSLA Steels for Cold Forming显示文摘The industrial level production of ultrafine grained(or ultrafine ferrite)ferrous alloys was investigated through three examples of steels that complied with the EN 10149-2 Euronorm and were produced by advanced controlled hot rolling techniques.The steel samples were tension tested and chemically analyzed,and the microstructure was evaluated through quantitative metallographic techniques to determine parameters such as yield stress,amount of microalloying elements,strain hardening coefficient,grain size,and grain size distribution.These steels were microalloyed with Ti,Nb,and Mn with ASTM grain sizes of approximately 13-15.The careful control of chemical composition and deformation during production,giving a specific attention to the deformation sequences,austenite non-recrystallization temperatures and allotropic transformations during cooling,are indispensable to obtain steels with an adequate strain hardening coefficient that allows cold working operations such as bending,stretching or drawing. | R González J O García M A Barbés M J Quintana L F Verdeja J I Verdeja | 2010 | Journal of Iron and Steel Research(International)2010，17，10： | 7 |
| 19 | Combined carriership of TLR9 -1237C and CD14 -260T alleles enhances the risk of developing chronic relapsing pouchitis显示文摘AIM: To investigate the single nucleotide polymorphisms (SNPs) in genes involved in bacterial recognition and the susceptibility to pouchitis or pouchitis severity.METHODS: Analyses of CD14 -260C>T, CARD15/NOD2 3020insC, Toll-like receptor (TLR)4 +896A>G,TLR9 -1237T>C, TLR9+ 2848G>A, and IRAKM +22148G>A SNPs were performed in 157 ileal-pouch anal anastomosis (IPAA) patients (79 patients who did not develop pouchitis, 43 infrequent pouchitis patients,35 chronic relapsing pouchitis patients) and 224 Italian Caucasian healthy controls.RESULTS: No significant differences were found in SNP frequencies between controls and IPAA patients.However, a significant difference in carriership frequency of the TLR9-1237C allele was found between the infrequent pouchitis and chronic relapsing pouchitis groups [P = 0.028, odd's ratio (OR) = 3.2, 95%CI = 1.2-8.6].This allele uniquely represented a 4-locus TLR9 haplotype comprising both studied TLR9 SNPs in Caucasians.Carrier trait analysis revealed an enhanced combined carriership of the alleles TLR9 -1237C and CD14 -260T in the chronic relapsing pouchitis and infrequent pouchitis group (P = 0.018, OR = 4.1, 95%CI = 1.4 -12.3).CONCLUSION: There is no evidence that the SNPs predispose to the need for IPAA surgery. The significant increase of the combined carriership of the CD14 -260T and TLR9 -1237C alleles in the chronic relapsing pouchitis group suggests that these markers identify a subgroup of IPAA patients with a risk of developing chronic or refractory pouchitis. | KM Lammers S Ouburg SA Morré JBA Crusius P Gionchetti F Rizzello C Morselli E Caramelli R Conte G Poggioli M Campieri AS Pea | 2005 | World Journal of Gastroenterology2005，11，46： | 7 |
