2Recent advances in gastric cancer early diagnosis显示文摘Gastric cancer(GC) remains an important cause of cancer death worldwide with a high mortality rate due to the fact that the majority of GC cases are diagnosed at an advanced stage when the prognosis is poor and the treatment options are limited. Unfortunately, the existing circulating biomarkers for GC diagnosis and prognosis display low sensitivity and specificity and the GC diagnosis is based only on the invasive procedures such as upper digestive endoscopy. There is a huge need for less invasive or non-invasive tests but also highly specific biomarkers in case of GC. Body fluids such as peripheral blood, urine or saliva,stomach wash/gastric juice could be a source of specific biomarkers, providing important data for screening and diagnosis in GC. This review summarized the recently discovered circulating molecules such as microRNAs, long non-coding RNAs, circular RNAs, which hold the promise to develop new strategies for early diagnosis of GC.Laura Necula Lilia Matei Denisa Dragu Ana I Neagu Cristina Mambet Saviana Nedeianu Coralia Bleotu Carmen C Diaconu Mihaela Chivu-Economescu 2019World Journal of Gastroenterology2019,25,17:70
3Clinical and cost impact of intravenous proton pump inhibitor use in non-ICU patients显示文摘AIM:To assess the appropriateness of the indication and route of administration of proton-pump-inhibitors (PPIs) and their associated cost impact. METHODS:Data collection was performed prospec-tively during a 6-mo period on 340 patients who re-ceived omeprazole intravenously during their hospital stay in non-intensive care floors. Updated guidelines were used to assess the appropriateness of the indication and route of administration. RESULTS:Complete data collection was available for 286 patients which were used to assess intravenous (IV) PPIs utilization. Around 88% of patients were receiving PPIs for claimed stress ulcer prophylaxis (SUP) indication; of which,only 17% met the guideline criteria for SUP indication,14% met the criteria for non-steroidal-anti-inflammatory drugs-induced ulcer prophylaxis,while the remaining 69% were identifi ed as having an unjustified indication for PPI use. Theinitiation of IV PPIs was appropriate in 55% of pa-tients. Half of these patients were candidates for switching to the oral dosage form during their hos-pitalization,while only 36.7% of these patients were actually switched. The inappropriate initiation of PPIs via the IV route was more likely to take place on the medical floor than the surgical floor (53% vs 36%,P = 0.003). The cost analysis associated with the appro-priateness of the indication for PPI use as well as the route of administration of PPI revealed a possible saving of up to $17 732.5 and $14 571,respectively. CONCLUSION:This study highlights the over-utili-zation of IV PPIs in non-intensive care unit patients. Restriction of IV PPI use for justified indications and route of administration is recommended.Soumana C Nasser Jeanette G Nassif Hani I Dimassi 2010World Journal of Gastroenterology2010,16,8:23

5Clinical outcomes of isolated renal failure compared to other forms of organ failure in patients with severe acute pancreatitis显示文摘AIM To assess differences in clinical outcomes of isolated renal failure(RF) compared to other forms of organ failure(OF) in patients with severe acute pancreatitis(SAP).METHODS Using a prospectively maintained database of patients with acute pancreatitis admitted to a tertiary medical center between 2003 and 2016, those with evidence of persistent OF were classified to renal, respiratory, cardiovascular, or multi-organ(2 or more organs). Data regarding demographics, comorbidities, etiology of acute pancreatitis, and clinical outcomes were prospectively recorded. Differences in clinical outcomes after development of isolated RF in comparison to other forms of OF were determined using independent t and Mann-Whitney U tests for continues variables, and χ~2 test for discrete variables.RESULTS Among 500 patients with acute pancreatitis, 111 patients developed persistent OF: mean age was 54 years, and 75(67.6%) were male. Forty-three patients had isolated OF: 17(15.3%) renal, 25(21.6%) respiratory, and 1(0.9%) patient with cardiovascular failure. No differences in demographics, etiology of acute pancreatitis, systemic inflammatory response syndrome scores, or development of pancreatic necrosis were seen between patients with isolated RF vs isolated respiratory failure. Patients with isolated RF were less likely to require nutritional support(76.5% vs 96%, P = 0.001), ICU admission(58.8% vs 100%, P = 0.001), and had shorter mean ICU stay(2.4 d vs 15.7 d, P < 0.001), compared to isolated respiratory failure. None of the patients with isolated RF or isolated respiratory failure died.CONCLUSION Among patients with SAP per the Revised Atlanta Classification, approximately 15% develop isolated RF. This subgroup seems to have a less protracted clinical course compared to other forms of OF. Isolated RF might be weighed less than isolated respiratory failure in risk predictive modeling of acute pancreatitis.Amir Gougol Mohannad Dugum Anwar Dudekula Phil Greer Adam Slivka David C Whitcomb Dhiraj Yadav Georgios I Papachristou 2017World Journal of Gastroenterology2017,23,29:20
6广东龙窝花岗闪长质岩体的年代学、地球化学及岩石成因显示文摘龙窝岩体是南岭地区燕山早期具幔源组分贡献的花岗岩的典型代表,其主体岩性为花岗闪长岩,岩体中含有深色闪长质包体,锆石ELA-ICP-MS定年结果表明花岗闪长岩的形成年龄为169.1±2.5Ma,属中侏罗世岩浆活动的产物。地球化学特征上,该岩体铝弱过饱和(A/NKC=1.0~1.1),相对贫碱,富钾(K_2O/Na_2O=1.15~1.45),富轻稀土和大离子亲石元素(如Rb、Cs、Th、U),贫高场强元素(如Nb、Ti)。闪长质包体具有与寄主岩相似的矿物组合,但铁镁矿物含量及过渡族元素(V、CR、Co、Ni)丰度相对偏高,二者的主量和微量元素表现出混合成因的演化趋势。寄主岩与包体具有相近的Sr、Nd同位素组成,I_(Sr)和ε_(Nd)(t)值分别为0.70843~0.70995、-6.53~-8.89和0.70797~0.70882、-4.71~-9.24,均表现出壳幔混源花岗岩类岩石的特点。二元混合模拟计算显示寄主岩与包体成岩过程中地幔物质的混入比例分别为32.9%~40.4%和 31.8%~46.4%。通过对岩石产出构造背景及地质地球化学特征的综合分析,表明龙窝花岗闪长岩及其中的闪长质包体是在伸展-引张环境下,由幔源基性岩浆及其诱发的壳源长英质岩浆混合作用的产物。邱检生 胡建 McInnes B I A 蒋少涌 徐夕生 Allen C M 2004岩石学报2004,20,6:19

11Advances of multidetector computed tomography in the characterization and staging of renal cell carcinoma显示文摘Renal cell carcinoma(RCC) accounts for approximately 90%-95% of kidney tumors. With the widespread use of cross-sectional imaging modalities, more than half of RCCs are detected incidentally, often diagnosed at an early stage. This may allow the planning of more conservative treatment strategies. Computed tomography(CT) is considered the examination of choice for thedetection and staging of RCC. Multidetector CT(MDCT) with the improvement of spatial resolution and the ability to obtain multiphase imaging, multiplanar and threedimensional reconstructions in any desired plane brought about further improvement in the evaluation of RCC. Differentiation of RCC from benign renal tumors based on MDCT features is improved. Tumor enhancement characteristics on MDCT have been found closely to correlate with the histologic subtype of RCC, the nuclear grade and the cytogenetic characteristics of clear cell RCC. Important information, including tumor size, localization, and organ involvement, presence and extent of venous thrombus, possible invasion of adjacent organs or lymph nodes, and presence of distant metastases are provided by MDCT examination. The preoperative evaluation of patients with RCC was improved by depicting the presence or absence of renal pseudocapsule and by assessing the possible neoplastic infiltration of the perirenal fat tissue and/or renal sinus fat compartment.Athina C Tsili Maria I Argyropoulou 2015World Journal of Radiology2015,7,6:16

13miR-200 family expression is downregulated upon neoplastic progression of Barrett's esophagus显示文摘AIM: To investigate miR-200 family expression in Barrett's epithelium, gastric and duodenal epithelia, and esophageal adenocarcinoma. METHODS: Real-time reverse transcriptase-polymerase chain reaction was used to measure miR-200, ZEB1 and ZEB2 expression. Ingenuity Pathway Analysis of miR-200 targets was used to predict biological outcomes. RESULTS: Barrett's epithelium expressed lower levels of miR-141 and miR-200c than did gastric and duodenal epithelia (P < 0.001). In silico analysis indicated roles for the miR-200 family in molecular pathways that distinguish Barrett's epithelium from gastric and duodenalepithelia, and which control apoptosis and proliferation. All miR-200 members were downregulated in adenocarcinoma (P < 0.02), and miR-200c expression was also downregulated in non-invasive epithelium adjacent to adenocarcinoma (P < 0.02). The expression of all miR-200 members was lower in Barrett's epithelium derived high-grade dysplastic cell lines than in a cell line derived from benign Barrett's epithelium. We observed signif icant inverse correlations between miR-200 family expression and ZEB1 and ZEB2 expression in Barrett's epithelium and esophageal adenocarcinoma (P < 0.05). CONCLUSION: miR-200 expression might contribute to the anti-apoptotic and proliferative phenotype of Barrett's epithelium and regulate key neoplastic processes in this epithelium.Cameron M Smith David I Watson Mary P Leong George C Mayne Michael Z Michael Bas PL Wijnhoven Damian J Hussey 2011World Journal of Gastroenterology2011,17,8:13

16非胰岛素依赖型糖尿病冠状动脉疾病的危险因素:英国糖尿病前瞻性研究(UKPDS:23)显示文摘目的:评价2型糖尿病患者冠状动脉疾病的基线危险因素。设计:对2 693例资料完整的患者进行年龄和性别调整的逐步选择过程分析,以确定哪些冠状动脉疾病的危险因素应纳入 Cox 比例风险模型。对象:3 055例白人患者,平均年龄52岁,均新近诊断为2型糖尿病,且无动脉粥样硬化相关疾病的证据。平均随访期7.9年。335例患者于10年内出现冠状动脉疾病。结局评定:具有明确异常心电图的心绞痛、致死或非致死性心肌梗塞。结果:冠状动脉疾病与低密度脂蛋白胆固醇浓度升高、高密度脂蛋白胆固醇浓度降低、甘油三酯浓度升高、高血红蛋白 A_(1c)、高收缩压、高空腹血糖以及吸烟史密切相关。低密度脂蛋白胆固醇较高1/3对较低1/3区间的估计风险比为2.26(95%可信区间为1.70~3.00),高密度脂蛋白胆固醇为0.55(0.41~0.73),血红蛋白 A_(1c)为1.52(1.15~2.01),收缩压为1.82(1.34~2.47)。吸烟者的估计风险比为1.41(1.06~1.88)。结论:2型糖尿病患者中,存在冠状动脉疾病潜在的、可变的5种危险因素的交叉重叠影响。它们是低密度脂蛋白胆固醇浓度升高、高密度脂蛋白胆固醇浓度降低、高血压、高血糖和吸烟。R C Turner H Millns H A W Neil I M Stratton S E Manley D R Matthews R R Holman 赵维纲 1998英国医学杂志中文版1998,0,3:11
17蛋白酶激活受体2在载脂蛋白E缺陷小鼠的血管炎症和动脉粥样硬化中发挥关键作用显示文摘凝血系统与血管炎症密切相关,尽管其潜在机制仍不清楚。最近的研究结果表明,蛋白酶激活受体(protease-activated receptor,PAR)2——活化因子X(activated factor X,FXa)的主要受体之一——在血管细胞和白细胞中均有表达,这提示PAR-2可能参与炎症性疾病的发病机制。Hara T Phuong PT Fukuda D Yamaguchi K Murata C Nishimoto S Yagi S Kusunose K Yamada H Soeki T Wakatsuki T Imoto I Shimabukuro M Sata M 刘青 叶鹏 2018中华高血压杂志2018,26,6:11
18Insulin sensitizers in treatment of nonalcoholic fatty liver disease:Systematic review显示文摘AIM: To summarize the evidence available for the clinical effectiveness of insulin sensitizers in the treatment of nonalcoholic fatty liver disease (NAFLD) systematically. METHODS: Relevant articles were located using computer-assisted searches of Medline (1966-March 2006), EMBASE (1988-March 2006), CINAHL (1982-March 2003), Educational Resource Information Center (1966-March 2006), Library, Information Science & Technology Abstracts (1967-March 2006), Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects (1994-2006), dissertations in ProQuest and FirstSearch databases. Manual searches were made in the abstracts from meetings of the American Gastroenterological Association (1999-2006), and the American Association for the Study of Liver Diseases (2003-2005). Studies were retrieved using the following selection criteria: (1) clinical trials using insulin sensitizers in subjects with NAFLD, (2) adult patients, (3) published as full manuscripts or abstracts, and (4) English, Spanish, German, and French languages only. Data were abstracted independently by two reviewers following standardized procedures. A face-to- face comparison of data was conducted to ensure the completeness and reliability of the abstraction process. RESULTS: Nine studies were included, six using metformin and three using thiazolidinediones. Only two studies were placebo-controlled trials. The mediansample size for all studies was 18 subjects. In the placebo-controlled trials, metformin improved insulin resistance markers and liver function tests, but not histological scores. In the single-arm trials, metformin and thiazolidinediones improved insulin resistance markers and liver function tests, and beneficial histological changes were reported. There is limited high-quality information available from which to draw categorical conclusions about the clinical use of insulin sensitizers in NAFLD.CONCLUSION: Current information indicates that the use of insulin sensitizers in NAFLD improves insulin resistance and liver function. Histological changes must be corroborated in randomized controlled trials.Norberto C Chavez-Tapia Tonatiuh Barrientos-Gutierrez Felix I Tellez-ávila Francisco Sánchez-ávila Maria Antonieta Montao-Reyes Misael Uribe 2006World Journal of Gastroenterology2006,12,48:11
