| 1 | 皮质下小血管病诊断的共识声明显示文摘血管性认知损害是用于描述一组涉及大血管和小血管的散发性和遗传性异质性疾病的诊断术语。皮质下小血管病可导致腔隙性梗死和进行性白质损害。被称为宾斯旺格病(Binswanger's disease, BD)的进行性白质损害患者构成了从单纯血管性疾病到合并神经变性病变的疾病谱。BD患者是一个相对同质性的亚组,存在缺氧缺血、腔隙性梗死和炎症,它们协同作用破坏血脑屏障和髓鞘。通过临床、脑脊液、神经心理学和影像学检查获得的多模式疾病标记物能促进该亚组患者的鉴别。本共识声明确定了一系列基于基础病理学改变的潜在生物学标记物,这将有助于诊断以及将来协作性治疗试验的患者选择。 | Gary A Rosenberg Anders Wallin Joanna M Wardlaw Hugh S Markus Joan Montaner Leslie Wolfson Costantino Iadecola Berislav V Zlokovic Anne Joutel Martin Dichgans Marco Duering Reinhold Schmidt Amos D Korczyn Lea T Grinberg Helena C Chui Vladimir Hachinski 王训师 张劼 陈涵丰 俞娅美 徐子奇 罗本燕 | 2016 | 国际脑血管病杂志2016,24,6: | 18 |
| 2 | H pylori (CagA) and Epstein-Barr virus infection in gastric carcinomas:Correlation with p53 mutation and c-Myc,Bcl-2 and Bax expression显示文摘AIM: To investigate the interrelationship between H pylori and Epstein-Barr virus (EBV) infection in the gastric carcinogenesis having in focus the p53 mutation and the c-Myc, Bcl-2 and Bax expression. METHODS: seventy-one gastric carcinoma tissues were assessed by polymerase chain reaction (PCR) for H pylori and in situ hybridization for EBV. c-Myc, Bcl-2 and Bax expression were detected by immunohistochemistry and single-stranded conformational polymorphism (SSCP) for p53 mutation. RESULTS: The positivity rates for H pylori and EBV were 94.4% and 8.45%, respectively. The majority of the cases displayed only the H pylori presence. All EBV positive cases were also H pylori positive. None infectious agent was observed in 5.55% of the cases. The intestinal type tumor was more frequent in the co-infected and non-infected groups. The female predominated in the non-infected group showing statistical significance (70.4% vs 29.6%, P=0.039). The Bcl-2 was only detected in the group exclusively infected by H pylori. However, c-Myc and Bax were detected in the three groups but with a low frequency in the co-infected group. Mutation of p53 was present in all groups, with the highest frequencies in the H pylori positive groups. CONCLUSION: The frequency of H pylori infection in gastric carcinomas was high. The presented data indicated that gastric carcinogenesis has different pathways depending of the presence of the two investigated infectious agents, suggesting a possible involvement of H pylori with apoptotic process. The low expression of c-Myc and Bax in the EBV-positive groups suggests that EBV may inhibit the expression of these proteins. Nevertheless, p53 mutation shows to be a relevant alteration, independent of both infectious agents. | Valeska Portela Lima Marcos Antonio Pereira de Lima Angela Rosa André Márcia Valéria Pitombeira Ferreira Marcos Aurélio Pessoa Barros Sílvia Helena Barem Rabenhorst | 2008 | World Journal of Gastroenterology2008,14,6: | 17 |

| 4 | Helicobacter pylori infection as a cause of iron deficiency anaemia of unknown origin显示文摘AIM: To assess the aetiological role of Helicobacter pylori (H. pylori) infection in adult patients with ironrefractory or iron-dependent anaemia of previously unknown origin. METHODS: Consecutive patients with chronic irondeficient anaemia (IDA) with H. pylori infection and a negative standard work-up were prospectively evaluated. All of them had either iron refractoriness or iron dependency. Response to H. pylori eradication was assessed at 6 and 12 mo from follow-up. H. pylori infection was considered to be the cause of the anaemia when a complete anaemia resolution without iron supplements was observed after eradication. RESULTS: H. pylori was eradicated in 88 of the 89 patients. In the non-eradicated patient the four eradicating regimens failed. There were violations of protocol in 4 patients, for whom it was not possible to ascertain the cause of the anaemia. Thus, 84 H. pylori eradicated patients (10 men; 74 women) were available to assess the effect of eradication on IDA. H. pylori infection was considered to be the aetiology of IDA in 32 patients (38.1%; 95%CI: 28.4%-48.8%). This was more frequent in men/postmenopausal women than in premenopausal women (75% vs 23.3%; P < 0.0001) with an OR of 9.8 (95%CI: 3.3-29.6). In these patients, anaemia resolution occurred in the first follow-up visit at 6 mo, and no anaemia or iron deficiency relapse was observed after a mean follow-up of 21 ± 2 mo. CONCLUSION: Gastric H. pylori infection is a frequent cause of iron-refractory or iron-dependent anaemia of previously unknown origin in adult patients. | Helena Monzón Montserrat Forné Maria Esteve Mercé Rosinach Carme Loras Jorge C Espinós Josep M Viver Antonio Salas Fernando Fernández-Baares | 2013 | World Journal of Gastroenterology2013,19,26: | 13 |
| 5 | Interrelationship between chromosome 8 aneuploidy,C-MYC amplification and increased expression in individuals from northern Brazil with gastric adenocarcinoma显示文摘AIM: To investigate chromosome 8 numerical aberra- tions, C-MYC oncogene alterations and its expression in gastric cancer and to correlate these findings with histo- pathological characteristics of gastric tumors. METHODS: Specimens were collected surgically from seven patients with gastric adenocarcinomas. Immu- nostaining for C-MYC and dual-color fluorescence in situ hybridization (FISH) for C-MYC gene and chromosome 8 centromere were performed. RESULTS: All the cases showed chromosome 8 aneu- ploidy and C-MYC amplification, in both the diffuse and intestinal histopathological types of Lauren. No significant difference (P < 0.05) was observed between the level ofchromosome 8 ploidy and the site, stage or histological type of the adenocarcinomas. C-MYC high amplification, like homogeneously stained regions (HSRs) and double minutes (DMs), was observed only in the intestinal-type. Structural rearrangement of C-MYC, like translocation, was observed only in the diffuse type. Regarding C-MYC gene, a significant difference (P < 0.05) was observed between the two histological types. The C-MYC protein was expressed in all the studied cases. In the intestinal- type the C-MYC immunoreactivity was localized only in the nucleus and in the diffuse type in the nucleus and cytoplasm. CONCLUSION: Distinct patterns of alterations between intestinal and diffuse types of gastric tumors support the hypothesis that these types follow different genetic path- ways. | Danielle Queiroz Calcagno Mariana Ferreira Leal Aline Damaceno Seabra Andre Salim Khayat Elizabeth Suchi Chen Samia Demachki Paulo Pimentel Assumpcao Mario Henrique Girao Faria Silvia Helena Barem Rabenhorst Márcia Valéria Pitombeira Ferreira Marília de Arruda Cardoso Smith Rommel Rodríguez Burbano | 2006 | World Journal of Gastroenterology2006,12,38: | 9 |
| 6 | 通过手术导致的重量损失由胃绕过在疾病的肥胖的病人改进非含酒精的脂肪肝疾病显示文摘 AIM:To evaluate the effects of surgical weight loss(Roux-en-Y gastric bypass with a modified Fobi-Capella technique) on non alcoholic fatty liver disease in obese patients.METHODS:A group of 26 morbidly obese patients aged 45 ± 2 years and with a body mass index > 40 kg/m 2 who underwent open surgical weight loss operations had paired liver biopsies,the first at surgery and the second after 16 ± 3 mo of weight loss.Biopsies were evaluated and compared in a blinded fashion.The presence of metabolic syndrome,anthropometric and biochemical variables were also assessed at baseline and at the time of the second biopsy.RESULTS:Percentage of excess weight loss was 72.1% ± 6.6%.There was a reduction in prevalence of metabolic syndrome from 57.7%(15 patients) to 7.7%(2 patients)(P < 0.001).Any significance difference was observed in aspartate aminotransferase or alanine aminotransferase between pre and postsurgery.There were improvements in steatosis(P < 0.001),lobular(P < 0.001) and portal(P < 0.05) inflammation and fibrosis(P < 0.001) at the second biopsy.There were 25(96.1%) patients with non alcoholic steatohepatitis(NASH) in their index biopsy and only four(15.3%) of the repeat biopsies fulfilled the criteria for NASH.The persistence of fibrosis(F > 1) was present in five patients at second biopsy.Steatosis and fibrosis at surgery were predictors of significant fibrosis postsurgery.CONCLUSION:Restrictive mildly malabsorptive surgery provides significant weight loss,resolution of metabolic syndrome and associated abnormal liver histological features in most obese patients. | Víctor Vargas Helena Allende Albert Lecube Maria Teresa Salcedo Juan A Baena-Fustegueras José M Fort Joaquín Rivero Roser Ferrer Roberto Catalán Eva Pardina Santiago Ramón y Cajal Jaime Guardia Julia Peinado-Onsurbe | 2012 | World Journal of Hepatology2012,4,12: | 6 |
| 7 | Cost-utility of molecular adsorbent recirculating system treatment in acute liver failure显示文摘AIM:To determine the short-term cost-utility of mo-lecular adsorbent recirculating system(MARS) treatment in acute liver failure(ALF).METHODS:A controlled retrospective study was conducted with 90 ALF patients treated with MARS from 2001 to 2005.Comparisons were made with a historical control group of 17 ALF patients treated from 2000 to 2001 in the same intensive care unit(ICU) specializing in liver diseases.The 3-year outcomes and number of liver transplantations were recorded.All direct liver disease-related medical expenses from 6 mo before to 3 years after ICU treatment were determined for 31 MARS patients and 16 control patients.The health-related quality of life(HRQoL) before MARS treatment was estimated by a panel of ICU doctors and after MARS using a mailed 15D(15-dimensional generic healthrelated quality of life instrument) questionnaire.The HRQoL,cost,and survival data were combined and the incremental cost/quality-adjusted life years(QALYs) was calculated.RESULTS:In surviving ALF patients,the health-related quality of life after treatmeant was generally high and comparable to the age-and gender-matched general Finnish population.Compared to the controls,the average cost per QALY was considerably lower in the MARS group(64 732€ vs 133 858€) within a timeframe of 3.5 years.The incremental cost of standard medical treatment alone compared to MARS was 10 928€,and the incremental number of QALYs gained by MARS was 0.66.CONCLUSION:MARS treatment combined with standard medical treatment for ALF in an ICU setting is more cost-effective than standard medical treatment alone. | Taru Kantola Suvi Mklin Anna-Maria Koivusalo Pirjo Rsnen Anne Rissanen Risto Roine Harri Sintonen Krister Hckerstedt Helena Isoniemi | 2010 | World Journal of Gastroenterology2010,16,18: | 3 |

| 12 | Simultaneous follow-up of mouse colon lesions by colonoscopy and endoluminal ultrasound biomicroscopy显示文摘AIM:To evaluate the potential use of colonoscopy and endoluminal ultrasonic biomicroscopy(eUBM)to track the progression of mouse colonic lesions.METHODS:Ten mice were treated with a single azoxy-methane intraperitoneal injection(week 1)followed by seven days of a dextran sulfate sodium treatment in their drinking water(week 2)to induce inflammationassociated colon tumors.eUBM was performed simultaneously with colonoscopy at weeks 13,17-20 and21.A 3.6-F diameter 40 MHz mini-probe catheter was used for eUBM imaging.The ultrasound mini-probe catheter was inserted into the accessory channel of a pediatric flexible bronchofiberscope,allowing simultaneous acquisition of colonoscopic and eUBM images.During image acquisition,the mice were anesthetized with isoflurane and kept in a supine position over a stainless steel heated surgical waterbed at 37℃.Both eUBM and colonoscopic images were captured and stored when a lesion was detected by colonoscopy or when the eUBM image revealed a modified colon wall anatomy.During the procedure,the colon was irrigated with water that was injected through a flush port on the mini-probe catheter and that acted as the ultrasound coupling medium between the transducer and the colon wall.Once the acquisition of the last eUBM/colonoscopy section for each animal was completed,the colons were fixed,paraffin-embedded,and stained with hematoxylin and eosin.Colon images acquired at the first time-point for each mouse were compared with subsequent eUBM/colonoscopic images of the same sites obtained in the following acquisitions to evaluate lesion progression.RESULTS:All 10 mice had eUBM and colonoscopic images acquired at week 13(the first time-point).Two animals died immediately after the first imaging acquisition and,consequently,only 8 mice were subjected to the second eUBM/colonoscopy imaging acquisition(at the second time-point).Due to the advanced stage of colonic tumorigenesis,5 animals died after the second time-point image acquisition,and thus,only three were subjected to the third eUBM/colonoscopy imaging acquisition(the third time-point).eUBM was able to detect the four layers in healthy segments of colon:the mucosa(the first hyperechoic layer moving away from the mini-probe axis),followed by the muscularis mucosae(hypoechoic),the submucosa(the second hyperechoic layer)and the muscularis externa(the second hypoechoic layer).Hypoechoic regions between the mucosa and the muscularis externa layers represented lymphoid infiltrates,as confirmed by the corresponding histological images.Pedunculated tumors were represented by hyperechoic masses in the mucosa layer.Among the lesions that decreased in size between the first and third time-points,one of the lesions changed from a mucosal hyperplasia with ulceration at the top to a mucosal hyperplasia with lymphoid infiltrate and,finally,to small signs of mucosal hyperplasia and lymphoid infiltrate.In this case,while lesion regression and modification were observable in the eUBM images,colonoscopy was only able to detect the lesion at the first and second time-points,without the capacity to demonstrate the presence of lymphoid infiltrate.Regarding the lesions that increased in size,one of them started as a small elevation in the mucosa layer and progressed to a pedunculated tumor.In this case,while eUBM imaging revealed the lesion at the first time-point,colonoscopy was only able to detect it at the second time-point.All colonic lesions(tumors,lymphoid infiltrate and mucosal thickening)were identified by eUBM,while colonoscopy identified just76%of them.Colonoscopy identified all of the colonic tumors but failed to diagnose lymphoid infiltrates and increased mucosal thickness and failed to differentiate lymphoid infiltrates from small adenomas.During the observation period,most of the lesions(approximately67%)increased in size,approximately 14%remained unchanged,and 19%regressed.CONCLUSION:Combining eUBM with colonoscopy improves the diagnosis and the follow-up of mouse colonic lesions,adding transmural assessment of the bowel wall. | Rossana C Soletti Kelly Z Alves Marcelo AP de Britto Dyanna G de Matos Mnica Soldan Helena L Borges Joo C Machado | 2013 | World Journal of Gastroenterology2013,19,44: | 1 |

| 15 | Metabolomic changes in fatty liver can be modified by dietary protein and calcium during energy restriction显示文摘AIM: To characterise the effect of energy restriction (ER) on liver lipid and primary metabolite profile by using metabolomic approach. We also investigated whether the effect of energy restriction can be further enhanced by modif ication of dietary protein source and calcium. METHODS: Liver metabolomic profile of lean and obese C57Bl/6J mice (n = 10/group) were compared with two groups of weight-reduced mice. ER was performed on control diet and whey protein-based high-calcium diet (whey + Ca). The metabolomicanalyses were performed using the UPLC/MS based lipidomic platform and the HPLC/MS/MS based primary metabolite platform. RESULTS: ER on both diets significantly reduced hepatic lipid accumulation and lipid droplet size, while only whey + Ca diet significantly decreased blood glucose (P < 0.001) and serum insulin (P < 0.01). In hepatic lipid species the biggest reduction was in the level of triacylglycerols and ceramides while the level of cholesterol esters was significantly increased during ER. Interestingly, diacylglycerol to phospholipid ratio, an indicator of relative amount of diabetogenic diglyceride species, was increased in the control ER group, but decreased in the whey + Ca ER group (P < 0.001, vs obese). ER on whey + Ca diet also totally reversed the obesity induced increase in the relative level of lipotoxic ceramides (P < 0.001, vs obese; P > 0.05, vs lean). These changes were accompanied with up-regulated TCA cycle and pentose phosphate pathway metabolites. CONCLUSION: ER-induced changes on hepatic metabolomic profile can be significantly affected by dietary protein source. The therapeutic potential of whey protein and calcium should be further studied. | Taru K Pilvi Tuulikki Seppnen-Laakso Helena Simolin Piet Finckenberg Anne Huotari Karl-Heinz Herzig Riitta Korpela Matej Orei Eero M Mervaala | 2008 | World Journal of Gastroenterology2008,14,28: | 1 |
