5Expression of matrix metalloproteinases 2 and 9 in human gastric cancer and superficial gastritis显示文摘AIM:To assess expression of matrix metalloproteinases 2(MMP2)and MMP9 in gastric cancer,superficial gastritis and normal mucosa,and to measure metalloproteinase activity.METHODS:MMP2 and MMP9 mRNA expression was determined by quantitative real-time polymerase chain reaction.Normalization was carried out using three different factors.Proteins were analyzed by quantitative gelatin zymography(qGZ).RESULTS:18S ribosomal RNA(18SRNA)was very highly expressed,while hypoxanthine ribosyltransferase-1(HPRT-1)was moderately expressed.MMP2 was highly expressed,while MMP9 was not detected or lowly expressed in normal tissues,moderately or highly expressed in gastritis and highly expressed in cancer.Relative expression of 18SRNA and HPRT-1 showed no significant differences.Significant differences in MMP2 and MMP9 were found between cancer and normal tissue,but not between gastritis and normal tissue.Absolute quantification of MMP9 echoed this pattern,but differential expression of MMP2 proved conflictive.Analysis by qGZ indicated significant differences between cancer and normal tissue in MMP-2,total MMP-9,250 and 110 kDa bands.CONCLUSION:MMP9 expression is enhanced in gastric cancer compared to normal mucosa;interpretation of differential expression of MMP2 is difficult to establish.Clara Luz Sampieri Sol de la Pea Mariana Ochoa-Lara Roberto Zenteno-Cuevas Kenneth León-Córdoba 2010World Journal of Gastroenterology2010,16,12:46
6不同加水量对北方馒头加工品质影响的研究显示文摘加水量是影响馒头加工品质的重要因素。用3种不同筋力的6个小麦面粉和5个水平加水量研究了加水量与北方馒头品质的关系。结果表明,在粉质仪测定的吸水率范围内,加水量显著影响馒头重量、体积、宽度、高度、比容及延展率。不同筋力面粉的馒头品质对加水量变化的敏感性不同。加水量与弱筋馒头表面亮度、色泽、光滑度、结构、压缩张弛性及总评分呈显著或极显著负相关(r=-0.663~-0.962),但在一定范围内,加水量增加能显著改善强筋馒头表面光滑度和内部结构(r=0.877,0.768)。强、中、弱筋面粉制作北方馒头的最适加水量分别为粉质仪吸水率(FWA)的85%、80%和70%~75%。压缩张弛性(SR)与强、中、弱筋馒头总评分呈极显著正相关,决定系数分别为0.94、0.88和0.72,可作为馒头品质评价的有效指标。陈东升 张艳 何中虎 王德森 Pea R J 2005作物学报2005,31,6:28
7Multidisciplinary approach to understand the pathogenesis of gastric cancer显示文摘Gastric carcinoma remains a common disease worldwide with a dismal prognosis. Therefore, it represents a very important health problem. It occurs with a high incidence in Asia and is one of the leading causes of cancer death in the world. Although the incidence and mortality of gastric carcinoma are decreasing in many countries,gastric cancer still represents the second most frequent malignancies in the world and the fourth in Europe. The 5-year survival rate of gastric carcinoma is low. The etiology and pathogenesis are not yet fully known. The study of gastric cancer is important in clinical medicine as well as in public health. Over the past 15 years,integrated research in molecular pathology has clarified the details of genetic and epigenetic abnormalities of cancer-related genes in the course of the development and progression of gastric cancer. Gastric cancer, as all cancers, is the end result of the interplay of many risk factors as well as protective factors. Although epidemiological evidence indicates that environmental factors play a major role in gastric carcinogenesis, the role of immunological, genetic, and immunogenetic factors are thought to contribute to the pathogenesis of gastric carcinoma. Among the environmental factors,diet and Helicobacter pylori are more amenable to intervention aimed at the prevention of gastric cancer.The aim of the present paper is to review and include the most recent published evidence to demonstrate that only a multidisciplinary approach will lead to the advancement of the pathogenesis and prevention of gastric cancer. On the immunogenetic research it is clear that evidence is accumulating to suggest that a genetic profile favoring the proinflammatory response increases the risk of gastric carcinoma.Juan Shang AS Pe(n|~)a 2005World Journal of Gastroenterology2005,11,27:16
8Efficacy of neoadjuvant therapy and surgical rescue for locally advanced hepatoblastomas:10 year single-center experience and literature review显示文摘AIM:To report our experience with long-term outcomes after multimodal management therapy.METHODS:An observational retrospective study was performed containing seven patients with hepatoblastoma(Hbl)treated in our institution,a tertiary referral center,from 2003 to 2011.Demographic,preoperative,surgical,and outcome variables were collected.A survival analysis and a review of the current literature related to combination neoadjuvant chemotherapy and surgical resection on Hbl were performed.RESULTS:The median age at surgery was 14.4 mo,with a male to female ratio of 4:3.Pretext staging at diagnosis was as follows:stageⅠ,4 cases;stageⅡ,2 patients;and stageⅢ,1 case.Mean pretreatment tumor volume was 735 cm3.Five out of seven patients received neoadjuvant chemotherapy according to SIOPEL-3 or SIOPEL-6 protocols.Tumor volume and alphafetoprotein levels significantly dropped after neoadjuvant therapy.Surgical procedures performed included hemihepatectomies,segmentectomies and atypical resection.All patients received chemotherapy after surgery.Median postoperative hospital stay was 8 d.All patients were alive and disease-free after a median follow-up period of 23 mo.With regards to the literature review,seventeen articles were found that were related to our search.CONCLUSION:Our series shows how multimodal management of Hbl,exhaustive control and a meticulous surgical approach leads to almost 100%complete resection with optimal postoperative results.Dolores Ayllon Teran Oscar Gómez Beltran Rubén Ciria Bru Elena Mateos González María José Pea Rosa Antonio Luque Molina Pedro López Cillero Javier Briceo Delgado 2014World Journal of Gastroenterology2014,20,29:12

10Effect of calcination temperature on structural properties and catalytic activity in oxidation reactions of LaNiO_3 perovskite prepared by Pechini method显示文摘The study presented the preparation of the perovskite oxide LaNiO3 by the complex citrate method, paying particular attention to evolution of its formation from the amorphous precursor with varied calcination temperatures. The products obtained after heat treatment under air between 200 and 800 ℃ were characterized by X-ray diffraction (XRD), thermogravimetric and differential thermal analysis (TG-DTA), Fourier transform infrared spectroscopy (FTIR), SBET measurements and X-ray photoelectron spectroscopy (XPS). The results showed the formation of a single phase with perovskite structure from ca. 550 ℃. Tests on the two catalytic oxidation reactions of C3H6 and CO over the system calcined between mentioned temperatures were examined on the basis of characterization results and showed that optimum catalytic properties for such reactions were achieved for the perovskite calcined at 600 ℃. In turn, correlations between redox and catalytic properties were established on the basis of thermogravimetric temperature programmed reduction (TPR) analysis.K. Rida M.A. Pea E. Sastre A.

12Haplotype of prostaglandin synthase 2/cyclooxygenase 2 is involved in the susceptibility to inflammatory bowel disease显示文摘AIM: Prostaglandin G/H synthase 2 (PTGS2 or COX2) is one of the key factors in the cellular response to inflammation.PTGS2 is expressed in the affected intestinal segments of patients with inflammatory bowel diseases (IBD). In IBD patients, non-steroidal anti-inflammatory drugs, which have been shown to reduce both the production and activity of PTGS2, may activate IBD and aggravate the symptoms.We aimed at examining genetic variants of PTGS2 that may be risk factors for IBD.METHODS: We genotyped 291 individuals diagnosed with IBD and 367 controls from the Dutch population for the five most frequent polymorphisms of the PTGS2 gene.Clinical data were collected on all patients. DNA was extracted via normal laboratory methods. Genotyping was carried out using multiplex PCR followed by the Invader Assay and the 5' exonuclease assay (TaqMan). New polymorphism screening was performed by pre-screening with denaturing high-performance liquid chromatography,followed by fluorescent sequencing.RESULTS: Allele 5209G was weakly associated with Crohn's disease (odds ratio [OR] 1.63, 95% confidence interval [CI] 1.03-2.57), and allele 8473T with ulcerative colitis (OR 1.50, 95%CI 1.00-2.27). The haplotype including both alleles showed a strong association with IBD (OR 13.15, 95%CI 3.17-116.15). This haplotype, while rare (-0.3%) in the general population, is found more frequently in patients (3.5%).CONCLUSION: Our data suggest that this haplotype of PTGS2 contributes to the susceptibility of IBD.David G Cox J Bart A Crusius Petra HM Peeters H Bas Bueno-de-Mesquita A Salvador Pe(n|~)a Federico Canzian 2005World Journal of Gastroenterology2005,11,38:10
13Combined 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 Pea 2005World Journal of Gastroenterology2005,11,46:7
14CIMMYT小麦puroindoline基因型的进一步鉴定与分析显示文摘目的籽粒硬度是小麦市场分级和定价的重要依据,影响磨粉和食品加工品质。CIMMYT是我国最重要小麦引种地之一,研究其硬度基因型对我国小麦引种具有重要的应用价值。方法以CIMMYT常用的236份小麦亲本和高代品系为材料,采用改进的颗粒指数法、特异引物的PCR扩增和改进的SDS-PAGE凝胶电泳对其SKCS硬度及其puroindoine基因型进行鉴定和分析。结果202份硬质麦中,165份为PINA蛋白缺失类型;37份为Pinb-D1b类型,其中19份为非CIMMYT材料,18份亲本中均含有非CIMMYT材料。在34份软质麦中,有野生型、Pina-D1a/Pinb-D1i、Pina-D1c/Pinb-D1h、Pina-D1j/Pinb-D1i和Pina-D1a/Pinb-D1j共5种基因型。两种硬质类型中,Pina-D1b类型胚乳硬质程度明显高于(PSI硬度显著低于)Pinb-D1b类型;4种软质类型中,Pina-D1c/Pinb-D1h和Pina-D1a/Pinb-D1i类型胚乳硬质程度显著高于(PSI硬度显著低于)Pina-D1j/Pinb-D1i和Pina-D1a/Pinb-D1a类型。通过分析各类型的puroindoline基因序列发现,Pinb-D1h和Pinb-D1i编码同一种氨基酸,突变后仍表现为软质是因为第28位精氨酸变成色氨酸,其余软质变异类型色氨酸丰富区附近均未发生变化,这可能是导致其胚乳质地仍未变硬的主要原因。结论在先前研究基础上,本试验对CIMMYT小麦基因型作了进一步分析,发现系谱中没有外源材料的所有CIMMYT硬质麦均为Pina-D1b类型。从山羊草引进的软质突变类型之间存在一定硬度差异。陈锋 夏先春 Manila William Morten Lillemo Richard Trethowan Roberto J Peňa 何中虎 2006中国农业科学2006,39,8:6
15Denervated muscle extract promotes recovery of muscle atrophy through activation of satellite cells. An experimental study显示文摘Purpose: The objective of the present study was to determine whether a denervated muscle extract(DmEx) could stimulate satellite cell response in denervated muscle.Methods: Wistar rats were divided into 4 groups: normal rats, normal rats treated with DmEx, denervated rats, and denervated rats treated with DmEx. The soleus muscles were examined using immunohistochemical techniques for proliferating cell nuclear antigen, desmin, and myogenic differentiation antigen(MyoD), and electron microscopy was used for analysis of the satellite cells.Results: The results indicate that while denervation causes activation of satellite cells, DmEx also induces myogenic differentiation of cells localized in the interstitial space and the formation of new muscle fibers. Although DmEx had a similar effect in nature on innervated and denervated muscles, this response was of greater magnitude in denervated vs. intact muscles.Conclusion: Our study shows that treatment of denervated rats with DmEx potentiates the myogenic response in atrophic denervated muscles.Eduardo Aguera Salvador Castilla Evelio Luque Ignacio Jimena Ignacio Ruz-Caracuel Fernando Leiva-Cepas Jos Pea 2019Journal of Sport and Health Science2019,8,1:4
16Effects of cellulase and xylanase enzymes mixed with increasing doses of Salix babylonica extract on in vitro rumen gas production kinetics of a mixture of corn silage with concentrate显示文摘An in vitro gas production(GP) technique was used to investigate the effects of combining different doses of Salix babylonica extract(SB) with exogenous fibrolytic enzymes(EZ) based on xylanase(X) and cellulase(C), or their mixture(XC; 1:1 v/v) on in vitro fermentation characteristics of a total mixed ration of corn silage and concentrate mixture(50:50, w/w) as substrate. Four levels of SB(0, 0.6, 1.2 and 1.8 m L g–1 dry matter(DM)) and four supplemental styles of EZ(1 μL g–1 DM; control(no enzymes), X, C and XC(1:1, v/v) were used in a 4×4 factorial arrangement. In vitro GP(m L g–1 DM) were recorded at 2, 4, 6, 8, 10, 12, 24, 36, 48 and 72 h of incubation. After 72 h, the incubation process was stopped and supernatant p H was determined, and then filtered to determine dry matter degradability(DMD). Fermentation parameters, such as the 24 h gas yield(GY24), in vitro organic matter digestibility(OMD), metabolizable energy(ME), short chain fatty acid concentrations(SCFA), and microbial crude protein production(MCP) were also estimated. Results indicated that there was a SB?EZ interaction(P<0.0001) for the asymptotic gas production(b), the rate of gas production(c), GP from 6 to 72 h, GP2(P=0.0095), and GP4(P=0.02). The SB and different combination of enzymes supplementation influenced(P<0.001) in vitro GP parameters after 12 h of incubation; the highest doses of SB(i.e., 1.8 m L g–1 DM), in the absence of any EZ, quadratically increased(P<0.05) the initial delay before GP begins(L) and GP at different incubation times, with lowering b(quadratic effect, P<0.0001) and c(quadratic effect, P<0.0001; linear effect, P=0.0018). The GP was the lowest(P<0.05) when the highest SB level was combined with cellulose. There were SB?EZ interactions(P<0.001) for OMD, ME, the partitioning factor at 72 h of incubation(PF72), GY24, SCFA, MCP(P=0.0143), and p H(P=0.0008). The OMD, ME, GY24 and SCFA with supp lementation of SB extract at 1.8 m L g–1 DM were higher(P<0.001) than the other treatments, however,PF72 was lower(quadratic effect, P=0.0194) than the other levels. Both C and X had no effect(P>0.05) on OMD, p H, ME, GY24, SCFA and MP. The combination of SB with EZ increased(P<0.001) OMD, ME, SCFA, PF72 and GP24, whereas there was no impact on p H. It could be concluded that addition of SB extract, C, and X effectively improved the in vitro rumen fermentation, and the combination of enzyme with SB extract at the level of 1.2 m L g–1 was more effective than the other treatments.Abdelfattah Z M Salem German Buendía-Rodríguez Mona M M Elghandour María A Mariezcurrena Berasain Francisco J Pea Jiménez Alberto B Pliego Juan C V Chagoyán María A Cerrillo Miguel A Rodríguez 2015Journal of Integrative Agriculture2015,14,1:4
17Coeliac disease in Dutch patients with Hashimoto’s thyroiditis and vice versa显示文摘AIM: To define the association between Hashimoto’s thyroiditis and coeliac disease in Dutch patients. METHODS: A total of 104 consecutive patients with Hashimoto’s thyroiditis underwent coeliac serological tests (antigliadins, transglutaminase and endomysium antibodies) and HLA-DQ typing. Small intestinal biopsy was performed when any of coeliac serological tests was positive. On the other hand, 184 patients with coeliac disease were subjected to thyroid biochemical (thyroid stimulating hormone and free thyroxine) and thyroid serological tests (thyroglobulin and thyroid peroxidase antibodies). RESULTS: Of 104 patients with Hashimoto’s thyroiditis, sixteen (15%) were positive for coeliac serology and five patients with documented villous atrophy were diagnosed with coeliac disease (4.8%; 95% CI 0.7-8.9). HLA-DQ2 (and/or -DQ8) was present in all the five and 53 patients with Hashimoto’s thyroiditis (50%; 95% CI 43-62). Of 184 patients with coeliac disease, 39 (21%) were positive for thyroid serology. Based on thyroid biochemistry, the 39 patients were subclassified into euthyroidism in ten (5%; 95% CI 2-9), subclinicalhypothyroidism in seven (3.8%; 95% CI 1.8-7.6), and overt hypothyroidism (Hashimoto’s thyroiditis) in 22 (12%; 95% CI 8-16). Moreover, four patients with coeliac disease had Graves’ disease (2%; 95% CI 0.8-5) and one patient had post-partum thyroiditis. CONCLUSION: The data from a Dutch population confirm the association between Hashimoto’s thyroiditis and coeliac disease. Screening patients with Hashimoto’s thyroiditis for coeliac disease and vice versa is recom- mended.Muhammed Hadithi Hans de Boer Jos WR Meijer Frans Willekens Jo A Kerckhaert Roel Heijmans Amado Salvador Pea Coen DA Stehouwer Chris JJ Mulder 2007World Journal of Gastroenterology2007,13,11:4

19Retrospective analysis of old-age colitis in the Dutch inflammatory bowel disease population显示文摘AIM: To describe the characteristics of Dutch patients with chronic inflammatory bowel disease (IBD) first diagnosed above 60 years of age-a disease also known as old-age colitis (OAC) and to highlight a condition that has a similar appearance to IBD, namely segmen- tal colitis associated with diverticular disease (SCAD). METHODS: A retrospective longitudinal survey of patient demographic and clinical characteristics, disease characteristics, diagnostic methods, management and course of disease was performed. The median follow-up period was 10 years. RESULTS: Of a total of 1100 IBD patients attending the Department of Gastroenterology, 59 (5%) [median age 82 years (range 64-101); 25 male (42%)] were identified. These patients were diagnosed with ulcerative colitis (n = 37, 61%), Crohn’s disease (n = 14, 24%), and indeterminate colitis (n = 8, 15%). Remission was induced in 40 (68%) patients within a median interval of 6 mo (range 1-21) and immunosuppressive therapy was well tolerated. Histological evaluation based on many biopsy samples and the course of the disease led to other diagnosis, namely SCAD instead of IBD in five (8%) patients. CONCLUSION: OAC is not an infrequent problem for the gastroenterologist, and should be considered in the evaluation of older patients with clinical featuressuggestive of IBD. Extra awareness and extensive biopsy sampling are required in order to avoid an erroneous diagnosis purely based on histological mimicry of changes seen in SCAD, when diagnosing IBD in the presence of diverticulosis coli.Muhammed Hadithi Marcel Cazemier Gerrit A Meijer Elisabeth Bloemena Richel J Felt-Bersma Chris J Mulder Stephan GM Meuwissen Amado Salvador Pea Adriaan A van Bodegraven 2008World Journal of Gastroenterology2008,14,20:3
20Effect of B vitamin supplementation on plasma homocysteine levels in celiac disease显示文摘AIM: To investigate the effect of vitamin supplements on homocysteine levels in patients with celiac disease. METHODS: Vitamin B6, folate, vitamin B12, and fasting plasma homocysteine levels were measured in 51 consecutive adults with celiac disease [median (range) age 56 (18-63) years; 40% men, 26 (51%) had villous atrophy, and 25 (49%) used B-vitamin supplements] and 50 healthy control individuals matched for age and sex. Finally, the C677T polymorphism of 5,10-methylene tetrahydrofolate reductase (MTHFR) was evaluated in 46 patients with celiac disease and all control individuals. RESULTS: Patients with celiac disease and using vitamin supplements had higher serum vitamin B6 (P = 0.003),folate (P < 0.001), and vitamin B12 (P = 0.012) levels than patients who did not or healthy controls (P = 0.035, P < 0.001, P = 0.007, for vitamin B6, folate, and vitamin B12, respectively). Lower plasma homocysteine levels were found in patients using vitamin supplements than in patients who did not (P = 0.001) or healthy controls (P = 0.003). However, vitamin B6 and folate, not vitamin B12, were significantly and independently associated with homocysteine levels. Twenty-four (48%) of 50 controls and 23 (50%) of 46 patients with celiac disease carried the MTHFR thermolabile variant T-allele (P = 0.89). CONCLUSION: Homocysteine levels are dependent on Marsh classification and the regular use of B-vitamin supplements is effective in reduction of homocysteine levels in patients with celiac disease and should be considered in disease management.Muhammed Hadithi Chris JJ Mulder Frank Stam Joshan Azizi J Bart A Crusius Amado Salvador Pea Coen DA Stehouwer Yvo M Smulders 2009World Journal of Gastroenterology2009,15,8:3
