| 1 | Promoter hypermethylation of CDH1, FHIT, MTAP and PLAGL1 in gastric adenocarcinoma in individuals from Northern Brazil显示文摘AIM: To evaluate the methylation status of CDH1, FHIT, MTAP and PLAGL1 promoters and the association of these findings with clinico-pathological characteristics. METHODS: Methylation-specific PCR (MSP) assay was performed in 13 nonneoplastic gastric adenocarcinoma, 30 intestinal-type gastric adenocarcinoma and 35 diffuse- type gastric adenocarcinoma samples from individuals in Northern Brazil. Statistical analyses were performed using the chi-square or Fisher’s exact test to assess associations between methylation status and clinico- pathological characteristics. RESULTS: Hypermethylation frequencies of CDH1, FHIT, MTAP and PLAGL1 promoter were 98.7%, 53.9%, 23.1% and 29.5%, respectively. Hypermethylation of three or four genes revealed a significant association with diffuse-type gastric cancer compared with nonneoplastic cancer. A higher hypermethylation frequency wassignificantly associated with H pylori infection in gastric cancers, especially with diffuse-type. Cancer samples without lymph node metastasis showed a higher FHIT hypermethylation frequency. MTAP hypermethylation was associated with H pylori in gastric cancer samples, as well as with diffuse-type compared with intestinal-type. In diffuse-type, MTAP hypermethylation was associated with female gender. CONCLUSION: Our findings show differential gene methylation in tumoral tissue, which allows us to conclude that hypermethylation is associated with gastric carcinogenesis. MTAP promoter hypermethylation can be characterized as a marker of diffuse-type gastric cancer, especially in women and may help in diagnosis, prognosis and therapies. The H pylori infectious agent was present in 44.9% of the samples. This infection may be correlated with the carcinogenic process through the gene promoter hypermethylation, especially the MTAP promoter in diffuse-type. A higher H pylori infection in diffuse-type may be due to greater genetic predisposition. | Mariana Ferreira Leal Eleonidas Moura Lima Patrícia Natália Oliveira Silva Paulo Pimentel Assumpo Danielle Queiroz Calcagno Spencer Luiz Marques Payo Rommel Rodríguez Burbano Marília de Arruda Cardoso Smith | 2007 | World Journal of Gastroenterology2007,13,18: | 24 |
| 2 | Laparoscopic liver resection:Experience based guidelines显示文摘Laparoscopic liver resection(LLR) has been progressively developed along the past two decades. Despite initial skepticism, improved operative results made laparoscopic approach incorporated to surgical practice and operations increased in frequency and complexity. Evidence supporting LLR comes from case-series, comparative studies and meta-analysis. Despite lack of level 1 evidence, the body of literature is stronger and existing data confirms the safety, feasibility and benefits of laparoscopic approach when compared to open resection. Indications for LLR do not differ from those for open surgery. They include benign and malignant(both primary and metastatic) tumors and living donor liver harvesting. Currently, resection of lesions located on anterolateral segments and left lateral sectionectomy are performed systematically by laparoscopy in hepatobiliary specialized centers. Resection of lesions located on posterosuperior segments(1, 4a, 7, 8) and major liver resections were shown to be feasible but remain technically demanding procedures, which should be reserved to experienced surgeons. Hand-assisted and laparoscopy-assisted procedures appeared to increase the indications of minimally invasive liver surgery and are useful strategies applied to difficult and major resections. LLR proved to be safe for malignant lesions and offers some short-term advantages over open resection. Oncological results including resection margin status and long-term survival were not inferior to open resection. At present, surgical community expects high quality studies to base the already perceived better outcomes achieved by laparoscopy in major centers' practice. Continuous surgical training, as well as new technologies should augment the application of lap-aroscopic liver surgery. Future applicability of new technologies such as robot assistance and image-guided surgery is still under investigation. | fabricio ferreira coelho jaime arthur pirola kruger gilton marques fonseca raphael leonardo cunha araújo vagner birk jeismann marcos vinícius perini renato micelli lupinacci ivan cecconello paulo herman | 2016 | World Journal of Gastrointestinal Surgery2016,8,1: | 22 |
| 3 | Oral purgative and simethicone before small bowel capsule endoscopy显示文摘AIM:To evaluate small bowel cleansing quality,diagnostic yield and transit time,comparing three cleansing protocols prior to capsule endoscopy.METHODS:Sixty patients were prospectively enrolled and randomized to one of the following cleansing protocols:patients in Group A underwent a 24 h liquid diet and overnight fasting;patients in Group B followed protocol A and subsequently were administered 2 L of polyethylene glycol(PEG) the evening before the procedure;patients in Group C followed protocol B and were additionally administered 100 mg of simethicone 30 min prior to capsule ingestion.Small bowel cleansing was independently assessed by two experienced endoscopists and classified as poor,fair,good or excellent according to the proportion of small bowel mucosa under perfect conditions for visualization.When there was no agreement between the two endoscopists,the images were reviewed and discussed until a consensus was reached.The preparation was considered acceptable if > 50% or adequate if > 75% of the mucosa was in perfect cleansing condition.The amount of bubbles was assessed independently and it was considered significant if it prevented a correct interpretation of the images.Positive endoscopic findings,gastric emptying time(GET) and small bowel transit time(SBTT) were recorded for each examination.RESULTS:There was a trend favoring Group B in achieving an acceptable(including fair,good or excellent) level of cleansing(Group A:65%;Group B:83.3%;Group C:68.4%) [P = not significant(NS)] and favoring Group C in attaining an excellent level of cleansing(Group A:10%;Group B:16.7%;Group C:21.1%)(P = NS).The number of patients with an adequate cleansing of the small bowel,corresponding to an excellent or good classification,was 5(25%) in Group A,5(27.8%) in Group B and 4(21.1%) in Group C(P = 0.892).Conversely,7 patients(35%) in Group A,3 patients(16.7%) in Group B and 6 patients(31.6%) in Group C were considered to have poor small bowel cleansing(P = 0.417),with significant fluid or debris such that the examination was unreliable.The proportion of patients with a significant amount of bubbles was 50% in Group A,27.8% in Group B and 15.8% in Group C(P = 0.065).This was significantly lower in Group C when compared to Group A(P = 0.026).The mean GET was 27.8 min for Group A,27.2 min for Group B and 40.7 min for Group C(P = 0.381).The mean SBTT was 256.4 min for Group A,256.1 min for Group B and 258.1 min for Group C(P = 0.998).Regarding to the rate of complete examinations,the capsule reached the cecum in 20 patients(100%) in Group A,16 patients(88.9%) in Group B and 17 patients(89.5%) in Group C(P = 0.312).A definite diagnosis based on relevant small bowel endoscopic lesions was established in 60% of the patients in Group A(12 patients),44.4% in Group B(8 patients) and 57.8% in Group C(11 patients)(P = 0.587).CONCLUSION:Preparation with 2 L of PEG before small bowel capsule endoscopy(SBCE) may improve small bowel cleansing and the quality of visualization.Simethicone may further reduce intraluminal bubbles.No significant differences were found regarding GET,SBTT and the proportion of complete exploration or diagnostic yield among the three different cleansing protocols. | Bruno Joel Ferreira Rosa Mara Barbosa Joana Magalhes Ana Rebelo Maria Joo Moreira José Cotter | 2013 | World Journal of Gastrointestinal Endoscopy2013,5,2: | 21 |
| 4 | 短期针刺足三里对脂多糖诱导的大鼠急性肺损伤的预防作用(英文)显示文摘目的:研究短期手法针刺足三里治疗对脂多糖诱导的实验性大鼠急性肺损伤的预防作用。方法:根据是否进行脂多糖刺激及采用的针刺方法的不同,将32只 Wistar 大鼠随机分为4组,即正常对照组、模型组、假针刺组和针刺组,每组8只。假针刺组和针刺组大鼠行手法针刺治疗,连续治疗4 d,每次 5 min。第4天针刺后采用脂多糖刺激诱导大鼠急性肺损伤。第5天,收集外周血、支气管肺泡灌洗液和骨髓等进行白细胞计数。结果:血细胞计数和支气管肺泡灌洗液细胞计数提示,针刺可减轻急性肺损伤大鼠的炎性反应,假针刺也有轻微的效果。正常对照组和模型组大鼠无明显的炎性反应。与正常对照组比较,模型组肺泡灌洗液中细胞计数增加;与假针刺组比较,针刺组肺泡灌选液中细胞计数减少,但差异没有统计学意义。结论:预防性手法针刺足三里可减轻脂多糖诱导的大鼠急性肺损伤,但其相关免疫机制仍待进一步的研究。 | Arthur de Sá FERREIRA Januário Gomes Mourāo e LIMA Tatiana Pereira Teixeira FERREIRA Camila Madeira Tavares LOPES Rubens MEYER | 2009 | 中西医结合学报2009,7,10: | 21 |

| 6 | Discovery of the marine Eocene in the northern South China Sea显示文摘The nature of the Eocene stratigraphy of the South China Sea(SCS)has been a mystery for decades.In the southern SCS,the Eocene system with marine deposits is often considered as representing part of the‘Proto-South China Sea’[1].In the northern SCS,however,the Eocene is dominated by non-marine sequences of South China origin[2],probably also related to the Proto-SCS[3]. | Zhimin Jian Haiyan Jin Michael A Kaminski Fabricio Ferreira Baohua Li Pai-Sen Yu | 2019 | National Science Review2019,6,5: | 20 |
| 7 | 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 |
| 8 | WONCA研究论文摘要汇编——对乙酰氨基酚治疗脊椎疼痛和骨关节炎的疗效和安全性:对随机安慰剂对照试验的系统综述和荟萃分析显示文摘目的探讨对乙酰氨基酚(扑热息痛)治疗脊椎疼痛和骨关节炎(髋关节、膝关节)的有效性和安全性。设计系统综述和荟萃分析。数据来源Medline、荷兰医学文摘数据库(EMBase)、AMED、CINAHL、Web of Science、LILACS、国际药学文摘、Cochrane对照试验中心注册库,时间自建库至2014年12月。研究的纳入标准研究须为随机对照试验,比较扑热息痛和安慰剂治疗脊椎疼痛(颈痛或下腰痛)和骨关节炎(髋关节、膝关节)的疗效和安全性。数据的提取由2名独立的研究人员分别提取关于疼痛、失能和生活质量的数据。次要结果指标包括:不良反应、患者依从性和急救药物的使用。疼痛和失能评分转换为0(没有疼痛或失能)到100(疼痛加重和失能)的数值。采用随机效应模型计算加权均数差(WMD)或风险比(HR)以及95%可信区间(95%CI)。应用Cochrane协作工具对偏倚风险进行评估,采用GRADE方法对证据的质量进行评估,并对结论进行总结。结果共纳入12篇报道(13项随机试验)。对于下腰痛患者,扑热息痛在短期内减少疼痛强度〔WMD=-0.5,95%CI(-2.9,1.9)〕、失能〔WMD=0.4,95%CI(-1.7,2.5)〕或提高生活质量〔WMD=0.4,95%CI(-0.9,1.7)〕等方面均是无效的。对于髋关节炎或膝关节炎患者,扑热息痛在短期内减轻疼痛〔WMD=-3.7,95%CI(-5.5,1.9)〕、失能〔WMD=-2.9,95%CI(-4.9,0.9)﹞方面有显著作用,尽管在临床意义上不重要。报告任何不良反应〔HR=1.0,95%CI(0.9,1.1)〕、任何严重不良反应〔HR=1.2,95%CI(0.7,2.1)〕或因为不良事件退出研究〔HR=1.2,95%CI(0.9,1.5)〕的患者数量,在扑热息痛组和安慰剂组中类似。坚持治疗的患者数量〔HR=1.0,95%CI(0.9,1.1)〕和使用急救药物〔HR=0.7,95%CI(0.4,1.3)〕的患者数量,在两组之间也是相似的。扑热息痛组患者发生肝功能异常的概率是安慰剂组患者的4倍〔HR=3.8,95%CI(1.9,7.4)〕,但这种效应的临床意义是不确定的。结论扑热息痛在治疗腰痛方面是无效的,但可以对骨关节炎患者提供最小的短期利益。现有的临床实践指南推荐对下腰痛患者、髋关节或膝关节骨关节炎患者使用扑热息痛治疗,以上研究结果支持对这些推荐进行重新审议。 | Machado GC Maher CG Ferreira PH 本刊编辑部 | 2015 | 中国全科医学2015,18,15: | 17 |
| 9 | Deep sedation during gastrointestinal endoscopy: Propofol-fentanyl and midazolam-fentanyl regimens显示文摘AIM: To compare deep sedation with propofol-fentanyl and midazolam-fentanyl regimens during upper gastrointestinal endoscopy. METHODS: After obtaining approval of the research ethics committee and informed consent, 200 patients were evaluated and referred for upper gastrointestinal endoscopy. Patients were randomized to receive propofol-fentanyl or midazolam-fentanyl (n = 100/group).We assessed the level of sedation using the observer's assessment of alertness/sedation (OAA/S) score and bispectral index (BIS). We evaluated patient and physician satisfaction, as well as the recovery time and complication rates. The statistical analysis was performed using SPSS statistical software and included the MannWhitney test, χ 2 test, measurement of analysis of variance, and the κ statistic. RESULTS: The times to induction of sedation, recovery, and discharge were shorter in the propofolfentanyl group than the midazolam-fentanyl group. According to the OAA/S score, deep sedation events occurred in 25% of the propofol-fentanyl group and 11% of the midazolam-fentanyl group (P = 0.014). Additionally, deep sedation events occurred in 19% of the propofol-fentanyl group and 7% of the midazolamfentanyl group according to the BIS scale (P = 0.039). There was good concordance between the OAA/S score and BIS for both groups (κ = 0.71 and κ = 0.63, respectively). Oxygen supplementation was required in 42% of the propofol-fentanyl group and 26% of the midazolam-fentanyl group (P = 0.025). The mean time to recovery was 28.82 and 44.13 min in the propofolfentanyl and midazolam-fentanyl groups, respectively (P < 0.001). There were no severe complications in either group. Although patients were equally satisfied with both drug combinations, physicians were more satisfied with the propofol-fentanyl combination. CONCLUSION: Deep sedation occurred with propofolfentanyl and midazolam-fentanyl, but was more frequent in the former. Recovery was faster in the propofol-fentanyl group. | Marcos Eduardo Lera dos Santos Fauze Maluf-Filho Dalton Marques Chaves Sergio Eiji Matuguma Edson Ide Gustavo de Oliveira Luz Thiago Ferreira de Souza Fernanda C Simoes Pessorrusso Eduardo Guimares Hourneaux de Moura Paulo Sakai | 2013 | World Journal of Gastroenterology2013,19,22: | 16 |
| 10 | -765G > C COX-2 polymorphism may be a susceptibility marker for gastric adenocarcinoma in patients with atrophy or intestinal metaplasia显示文摘AIM: To investigate the relationship between the -765G > C COX-2 polymorphism and the development of different gastric lesions: atrophy or intestinal metaplasia and gastric adenocarcinoma. METHODS: A cross-sectional study was performed involving 320 Portuguese individuals (210 without evidence of neoplastic disease, 73 patients with gastric adenocarcinomas and 37 with atrophy or intestinal metaplasia) using a PCR-RFLP method. RESULTS: -765C allele was overrepresented in the patients with gastric adenocarcinoma (51%) when compared either with the control group (38%) or patients with atrophy or intestinal metaplasia (27%). Callele was found to be very common in our population (0.22), and a multivariate logistic regression analysis revealed nearly 3-fold increased risk for the progression to gastric adenocarcinoma in patients with atrophy or intestinal metaplasia carrying the -765C allele (OR = 2.67, 95% CI = 1.03-6.93; P = 0.04).considered as another susceptibility marker for gastric adenocarcinoma development in patients with atrophy or intestinal metaplasia. | Carina Pereira Hugo Sousa Paula Ferreira Maria Fragoso Luís Moreira-Dias Carlos Lopes Rui Medeiros Mário Dinis-Ribeiro | 2006 | World Journal of Gastroenterology2006,12,34: | 16 |
| 11 | Effects of cold and warm cross-rolling on microstructure and texture evolution of AZ31B magnesium alloy sheet显示文摘Mg alloys conventionally rolled often present strong basal textures that affect negatively further deformations,limiting their applications.The present research found that cross-rolling experiences in adequate conditions can weaken those intense basal textures as a result of the interaction of deformation mechanisms and dynamic recrystallization.The effects of rolling temperature and strain rate on the microstructure and texture of an AZ31B magnesium alloy sheet generated heterogeneous microstructure where the initial basal texture was strengthened during cold cross-rolling and it was gradually weakening by the rolling reduction and the rolling temperature increases in such a way that a rather weak basal fiber was produced applying reductions higher than 15%at temperatures higher than 200℃.Their ODF functions supported the texture weakening,exhibiting a combination of two crystallographic orientations represented by{0001}<211^(-)0>and{0001}<101^(-)0>. | Litzy Lina Choquechambi Catorceno Hamilton Ferreira Gomes de Abreu Angelo Fernando Padilha | 2018 | Journal of Magnesium and Alloys2018,6,2: | 16 |

| 13 | Immunoexpression of cyclooxygenase-2 in primary gastric carcinomas and lymph node metastases显示文摘AIM: To evaluate immunoexpression of cyclooxygenase-2 (COX-2) in primary gastric carcinomas and respective lymph node metastases. METHODS: Immunohistochemistry to analyze COX-2 expression was performed on tissue microarray slices obtained from 36 specimens of gastrectomy and satellite lymph nodes from patients with gastric carcinoma. RESULTS: Immunostaining was seen in most cases, and COX-2 expression was higher in lymph node me-tastases than in corresponding primary gastric tumors of intestinal, diffuse and mixed carcinomas, with a statistically signif icant difference in the diffuse histotype (P = 0.0108). CONCLUSION: COX-2 immunoexpression occurs frequently in primary gastric carcinomas, but higher expression of this enzyme is observed in lymph node metastases of the diffuse histotype. | Paulo RC Almeida Francisco VA Ferreira Cássio C Santos Francisco D Rocha-Filho Raul RP Feitosa Esther AA Falco Belise K Cavada Roberto CP Lima-Júnior Ronaldo A Ribeiro | 2012 | World Journal of Gastroenterology2012,18,8: | 14 |

| 19 | 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 |
