4室内TDR试验监测石灰矿渣加固粘性土的物理化学反应过程(英文)显示文摘石灰矿渣和水泥矿渣常用于加固道路基层的粘性土。目前现场一般采用未加固土的最大干密度和最优含水率来评价加固土的压实施工质量。但是粘性土掺加了石灰后,发生了复杂的物理化学反应,使得其压实特性与未加固土有很大的不同。采用时域反射计监测石灰加固土内的物理化学反应过程。试验时将不同石灰矿渣掺和量和含水率的Orchard粘土通过标准击实试验夯实于击实筒中,用TDR监测其中的物理化学反应,针式贯入仪监测强度的增长。试验发现,电导率和介电常数的变化反应了土中的离子交换和硬化反应的过程。初始电导率(1d之内)的减小揭示了石灰矿渣的掺和量的大小,而长期电导率的减小揭示了强度的增长。试验表明,时域反射计技术可用于评价石灰加固土的施工质量。陈仁朋 DAITA R K DRNEVICH V P KIM D H 2006岩土工程学报2006,28,2:7
5Aging related methylation influences the gene expression of key control genes in colorectal cancer and adenoma显示文摘AIM To analyze colorectal carcinogenesis and age-related DNA methylation alterations of gene sequences associated with epigenetic clock CpG sites. METHODS In silico DNA methylation analysis of 353 epigenetic clock Cp G sites published by Steve Horvath was performed using methylation array data for a set of 123 colonic tissue samples [64 colorectal cancer(CRC), 42 adenoma, 17 normal; GEO accession number: GSE48684]. Among the differentially methylated agerelated genes, secreted frizzled related protein 1(SFRP1) promoter methylation was further investigated in colonic tissue from 8 healthy adults, 19 normal children, 20 adenoma and 8 CRC patients using bisulfite-specific PCR followed by methylation-specific high resolution melting(MS-HRM) analysis. m RNA expression of age-related 'epigenetic clock' genes was studied using Affymetrix HGU133 Plus2.0 whole transcriptome data of 153 colonic biopsy samples(49 healthy adult, 49 adenoma, 49 CRC, 6 healthy children)(GEO accession numbers: GSE37364, GSE10714, GSE4183, GSE37267). Whole promoter methylation analysis of genes showing inverse DNA methylationgene expression data was performed on 30 colonic samples using methyl capture sequencing.RESULTS Fifty-seven age-related Cp G sites including hypermethylated PPP1R16 B, SFRP1, SYNE1 and hypomethylated MGP, PIPOX were differentially methylated between CRC and normal tissues(P < 0.05, ?β≥ 10%). In the adenoma vs normal comparison, 70 CpG sites differed significantly, including hypermethylated DKK3, SDC2, SFRP1, SYNE1 and hypomethylated CEMIP, SPATA18(P < 0.05, ?β≥ 10%). In MS-HRM analysis, the SFRP1 promoter region was significantly hypermethylated in CRC(55.0% ± 8.4 %) and adenoma tissue samples(49.9% ± 18.1%) compared to normal adult(5.2% ± 2.7%) and young(2.2% ± 0.7%) colonic tissue(P < 0.0001). DNA methylation of SFRP1 promoter was slightly, but significantly increased in healthy adults compared to normal young samples(P < 0.02). This correlated with significantly increased SFRP1 m RNA levels in children compared to normal adult samples(P < 0.05). In CRC tissue the mR NA expression of 117 agerelated genes were changed, while in adenoma samples 102 genes showed differential expression compared with normal colonic tissue(P < 0.05, logF C > 0.5). The change of expression for several genes including SYNE1, CLEC3 B, LTBP3 and SFRP1, followed the same pattern in aging and carcinogenesis, though not for all genes(e.g., MGP). CONCLUSION Several age-related DNA methylation alterations can be observed during CRC development and progression affecting the m RNA expression of certain CRC- and adenoma-related key control genes.Orsolya Galamb Alexandra Kalmár Barbara Kinga Barták árpád V Patai Katalin Leiszter Bálint Péterfia Barnabás Wichmann Gábor Valcz Gábor Veres Zsolt Tulassay Béla Molnár 2016World Journal of Gastroenterology2016,22,47:7
6一种miRNA标记在胶质瘤侵袭性表型的确定与预后评估中的价值(英文)显示文摘Gliomas represent a disparate group of tumours for which there are to date no cure. Thus,there is a recognized need for new diagnostic and therapeutic approaches based on increased understanding of their molecular nature. We performed the comparison of the microRNA( miRNA) profile of 8 WHO grade II gliomas and 24 higher grade tumours( 2 WHO grade III and 22 glioblastomas) by using the Affymetrix Gene Chip miRNA Array v. 1. 0. A relative quantification method( RT-q PCR) with standard curve was used to confirm the 22 miRNA signature resulted by array analysis. The prognostic performances of the confirmed miRNAs were estimated on the Tumor Cancer Genome Atlas( TCGA) datasets. We identified 22 miRNAs distinguishing grade II gliomas from higher grade tumours.RT-q PCR confirmed the differential expression in the two patients' groups for 13 out of the 22 miRNAs. The analysis of the Glioblastoma Multiforme( GBM) and Lower Grade Glioma( LGG) datasets from TCGA demonstrated the association with prognosis for 6 of those miRNAs. Moreover,in the GBM dataset miR-21 and miR-210 were predictors of worse prognosis in both univariable and multivariable Cox regression analyses( HR 1. 19,P = 0. 04,and HR 1. 18,P = 0. 029 respectively). Our results support a direct contribution of miRNAs to glioma cancerogenesis and suggest that miR-21 and miR-210 may play a role in the aggressive clinical behaviour of glioblastomas.Barbano R Palumbo O Pasculli B Galasso M Volinia S D'Angelo V Icolaro N Coco M Dimitri L Graziano P Copetti M Valori VM Maiello E Carella M Fazio VM Parrella P 2014中华神经外科疾病研究杂志2014,13,5:6
7肠道衍生的血清脂多糖与心房颤动患者主要不良心血管事件的风险增加相关:地中海膳食的影响显示文摘肠道微生物群正在成为动脉粥样硬化血栓形成的新型危险因素,但肠道衍生的脂多糖的预测作用尚不清楚。来自意大利罗马Sapienza大学的Pastori等进行了一项前瞻性单中心研究,分析了脂多糖与心房颤动中主要不良心血管事件(major adverse cardiovascular events,MACE)之间的关系,以及坚持地中海膳食(Mediterranean diet,Med-diet)对上述关系的影响。刘莉 叶鹏 Pastori D Carnevale R Nocella C Novo M Santulli M Cammisotto V Menichelli D Pignatelli P Violi F 2017中华高血压杂志2017,25,9:5

9欧洲和中国的心脏与肾脏远程缺血预适应研究:一项随机对照试验显示文摘远程缺血预适应(remote ischemic preconditioning,RIPC)对经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI)术后造影剂肾病(contrast-induced nephropathy,CIN)的潜在保护作用尚待确定。该研究为双盲、随机、安慰剂对照的多中心研究,纳入年龄〈85岁,肾清除率为30~60mL/(min·1.73m^2)的有临床适应证的患者,除了直接PCI外均按1∶1给予RIPC或标准治疗。主要终点是CIN的发生率。次要终点是围手术期心肌梗死(peri-procedural myocardial infarction,PMI)的发生率。刘青 叶鹏 Moretti C Cerrato E Cavallero E Lin S Rossi ML Picchi A Sanguineti F Ugo F Palazzuoli A Bertaina M Presbitero P Shao-Liang C Pozzi R Giammaria M Limbruno U Lefèvre T Gasparetto V Garbo R OmedèP Sheiban I Escaned J Biondi-Zoccai G Gaita F Perl L D'Ascenzo F 2018中华高血压杂志2018,26,4:3
10Hepatitis B infection among adults in the philippines:A national seroprevalence study显示文摘AIM:To determine the prevalence of hepatitis B surface antigen(HBsAg)seropositivity among adult Filipinos.METHODS:Testing for HBsAg was performed on serum samples from persons aged ≥ 20 years old who participated in the National Nutrition and Health Survey(NNHeS)conducted in 2003.Information on age,sex,marital status,educational attainment,employment status,and income were collected.For this study,marital status was classified as never married or otherwise(i.e.,married,divorced,separated,widowed);educational attainment was classified as high school graduate or below or at least some tertiary education;and employment status was classified as currently employed or currently unemployed.Annual income was divided into 4 quartiles in Philippine pesos(PhP):Q1,≤ PhP 53064;Q2,PhP 53065-92192;Q3,PhP 92193-173387;and Q4,≥ PhP 173388.Prevalence estimates were weighted so that they represented the general population.Social and demographic factors were correlated with HBsAg seropositivity.Multivariate analysis was used to determine independent predictors of HBsAg seropositivity.RESULTS:A total of 2150 randomly selected adults,20 years and over,out of the 4753 adult participants of NNHeS were tested for HBsAg.The HBsAg seroprevalence was 16.7%(95%CI:14.3%-19.1%),which corresponded to an estimated 7278968 persons infected with hepatitis B.There was no significant difference between males and females(17.5% vs 16.0%;P = 0.555).This corresponded to an estimated 3721775 men and 3557193 women infected with hepatitis B.The HBsAg seroprevalence peaked at age 20-39 years old,with declining prevalence in the older age groups.The only independent predictor of HBsAg seropositivity was the annual income,with persons in the highest income quartile being less likely to be HBsAg positive(age-adjusted OR = 0.51;95%CI:0.30-0.86)compared to subjects in the lowest income quartile.Sex,marital status,educational attainment,and employment status were not found to be independent predictors of HBsAg seropositivity.CONCLUSION:The high HBsAg seroprevalence among adults in the Philippines classifies the country as hyperendemic for HBV infection and appears unchanged over the last few decades.Stephen N Wong Janus P Ong Madalinee Eternity D Labio Oscar T Cabahug Maria Lourdes O Daez Erlinda V Valdellon Jose D Sollano Jr Marilyn O Arguillas 2013World Journal of Hepatology2013,5,4:3
11Macrophage secretory products induce an inflammatory phenotype in hepatocytes显示文摘AIM:To investigate the influence of macrophages on hepatocyte phenotype and function.METHODS:Macrophages were differentiated from THP-1 monocytes via phorbol myristate acetate stimulation and the effects of monocyte or macrophageconditioned medium on HepG2 mRNA and protein expression determined.The in vivo relevance of these findings was confirmed using liver biopsies from 147 patients with hepatitis C virus(HCV)infection.RESULTS:Conditioned media from macrophages,but not monocytes,induced a transient morphological change in hepatocytes associated with upregulation of vimentin(7.8±2.5-fold,P=0.045)and transforming growth factor(TGF)-β1(2.6±0.2-fold,P<0.001)and downregulation of epithelial cadherin(1.7±0.02-fold,P=0.017)mRNA expression.Microarray analysis revealed significant upregulation of lipocalin-2(17-fold,P <0.001)and pathways associated with inflammation,and substantial downregulation of pathways related to hepatocyte function.In patients with chronic HCV,realtime polymerase chain reaction and immunohistochemistry confirmed an increase in lipocalin-2 mRNA(F0 1.0 ±0.3,F1 2.2±0.2,F2 3.0±9.3,F3/4 4.0±0.8,P= 0.003)and protein expression(F1 1.0±0.5,F2 1.3± 0.4,F3/4 3.6±0.4,P=0.014)with increasing liver injury.High performance liquid chromatography-tandem mass spectrometry analysis identified elevated levels of matrix metalloproteinase(MMP)-9 in macrophageconditioned medium,and a chemical inhibitor of MMP-9 attenuated the change in morphology and mRNA expression of TGF-β1(2.9±0.2 vs 1.04±0.1,P<0.001) in macrophage-conditioned media treated HepG2 cells.In patients with chronic HCV infection,hepatic mRNA expression of CD163(F0 1.0±0.2,F1/2 2.8±0.3,F3/4 5.3±1.0,P=0.001)and MMP-9(F0 1.0±0.4,F1/2 2.8±0.3,F3/4 4.1±0.8,P=0.011)was significantly associated with increasing stage of fibrosis.CONCLUSION:Secreted macrophage products alter the phenotype and function of hepatocytes,with increased expression of inflammatory mediators,suggesting that hepatocytes actively participate in liver injury.Michelle Melino Victoria L Gadd Gene V Walker Richard Skoien Helen D Barrie Dinesh Jothimani Leigh Horsfall Alun Jones Matthew J Sweet Gethin P Thomas Andrew D Clouston Julie R Jonsson Elizabeth E Powell 2012World Journal of Gastroenterology2012,18,15:3

15Color Doppler sonography and angioscintigraphy in hepatic Hodgkin's lymphoma显示文摘AIM:To estimate the characteristics of Color Doppler findings and the results of hepatic radionuclide angiography (HRA) in secondary Hodgkin's hepatic lymphoma.METHODS:The research included patients with a diagnosis of Hodgkin's lymphoma with metastatic focal lesions in the liver and controls.Morphologic characteristics of focal liver lesions and hemodynamic parameters were examined by pulsed and Color Doppler in the portal,hepatic and splenic veins were examined.Hepatic perfusion index (HPI) estimated by HRA was calculated.RESULTS:In the majority of patients,hepatomegaly was observed.Lesions were mostly hypoechoic and mixed,solitary or multiple.Some of the patients presented with dilated splenic veins and hepatofugal blood flow.A pulse wave was registered in the centre and at the margins of lymphoma.The average velocity of the pulse wave was higher at the margins (P>0.05).A continuous venous wave was found only at the margins of lymphoma.There was no linear correlation between lymphoma size and velocity of pulse and continuous wave (r=390,P<0.01).HPI was significantly lower in patients with lymphomas than in controls (P<0.05),pointing out increased arterial perfusion in comparison to portal perfusion.CONCLUSION:Color Doppler ultrasonography is a sensitive method for the detection of neovascularization in Hodgkin's hepatic lymphoma and estimation of its intensity.Hepatic radionuclide angiography can additionally help in the assesment of vascularisation of liver lesions.Mirjana V Stojkovi Vera M Artiko Irena B Radoman Slavko J Knezevi Snezana M Luki Mirko D Kerkez Nebojsa S Leki Andrija A Anti Marinko M Zuvela Vitomir I Rankovi Milorad N Petrovi Dragana P obi Vladimir B Obradovi 2009World Journal of Gastroenterology2009,15,26:2
