6大别山双河和碧溪岭超高压变质岩流体包裹体研究显示文摘对大别山双河和碧溪岭含柯石英榴辉岩和硬玉石英岩进行了详细的流体包裹体研究。根据流体包裹体的成分和盐度的不同 ,可以划分出至少五种类型不同的气液包裹体 :( 1) N2 包裹体 ;( 2 )高盐度流体包裹体 ;( 3) CO2 包裹体 ;( 4) CO2 -H2 O包裹体 ;( 5 )低盐度流体包裹体。N2 包裹体仅见于含柯石英榴辉岩 ,而高盐度流体包裹体则几乎存在于所有的榴辉岩和硬玉石英岩中。 CO2 包裹体沿榴辉岩中微剪切带分布 ,或存在于强变形的硬玉石英岩中 ,而低盐度流体包裹体分布较为局限。N2 和高盐度流体被认为是超高压变质作用平衡的产物 ,来源于变质前的古孔隙流体。而且榴辉岩中含有一系列盐度不同的流体显微域 ,其大小与矿物颗粒相当。在板块折返过程中 ,包裹体中流体可能发生迁移 ,但是不会超出寄主晶体的范围。CO2流体明显是外来的 ,可能来自共生大理岩或含碳酸盐的变质沉积岩。这与菱镁矿和柯石英等共生组合所指示的进变质过程中大理岩不存在脱碳反应的结论相一致。而低盐度流体则可能系顶峰变质矿物分解而成 。傅斌 肖益林 J L R Touret A M Van den Kerkhof JHoefs 郑永飞 2000岩石学报2000,16,1:14
7Mesalazine preparations for the treatment of ulcerative colitis: Are all created equal?显示文摘Oral mesalazine(also known as mesalamine) is a 5-aminosalicylic acid compound used in the treatment of mild to moderate ulcerative colitis, with high rates of efficacy in induction and maintenance of remission.The therapeutic effect of mesalazine occurs topically at the site of diseased colonic mucosa. A myriad of oral mesalazine preparations have been formulated with various drug delivery methods to minimize systemic absorption and maximise drug availability at the inflamed colonic epithelium. It remains unclear whether different oral mesalazine formulations are bioequivalent. This review aims to evaluate the differences between mesalazine formulations based on the currently available literature and explore factors which may influence the selection of one agent above another.Bei Ye Daniel R van Langenberg 2015World Journal of Gastrointestinal Pharmacology and Therapeutics2015,6,4:14
8睾丸活检:临床操作及其诠释显示文摘睾丸活检许多年来被认为是不明病因男性不育和无精症诊断的基础。近来,男性不育指南都限定诊断性睾丸活检只能用于梗阻性无精子症(睾丸体积正常,生殖激素正常)的鉴别诊断。现今,睾丸活检取精技术与胞浆内单精子显微注射(ICSI)联用于非梗阻性无精子症患者的取精过程中。此外,睾丸活检还可以应用于有睾丸恶性肿瘤风险的患者的取精治疗中。研究一些不育男性后发现,不育患者患原位睾丸癌的风险越来越高,尤其是曾有隐睾症、睾丸恶性肿瘤病史,或患睾丸萎缩的患者。睾丸超声异常,比如睾丸微石症,实质内呈弥散分布,软细胞组织不均、睾丸组织损伤等,进一步增加了这些患者原位癌的发病率。准确的组织学分类,正确的组织处理和固定,样品准备和评估是必须的。同时,推荐使用标准的睾丸活检方法。另外,通过免疫组织化学法检测睾丸组织的肿瘤恶化程度是不可缺少的技术支持。本综述主要描述了睾丸活检用于男性不育临床诊断和治疗措施的最新进展。Gert R Dohle Saad Elzanaty Niels J van Casteren 2012Asian Journal of Andrology2012,14,1:13
9Osteopontin increases hepatocellular carcinoma cell growth in a CD44 dependant manner显示文摘AIM:To investigate the role of osteopontin(OPN) and its splice variants in the proliferation of hepatocellular carcinoma(HCC).METHODS:The expression of OPN variants in HCC cell lines as well as HCC tissue samples and nontumour tissue was studied using polymerase chain reaction.OPN variant cDNAs were cloned into a mammalian expression vector allowing both transient expression and the production of stable OPN expressing cell lines.OPN expression was studied in these cells using Western blotting,immunofluoresnce and enzyme linked immunosorbent assay.A CD44 blocking antibody and siRNA targeting of CD44 were used to examine the role of this receptor in the OPN stimulated cell growth observed in culture.Huh-7 cells stably expressing either OPN-A,-B or-C were injected subcutaneously into the flanks of nude mice to observe in vivo tumour growth.Expression of OPN mRNA and protein in these tumours was examined using reverse transcriptionpolymerase chain reaction and immunohistochemistry.RESULTS:OPN is expressed in HCC in 3 forms,the full length OPN-A and 2 splice variants OPN-B and-C.OPN variant expression was noted in HCC tissue as well as cognate surrounding cirrhotic liver tissue.Expression of these OPN variants in the HCC derived cell line Huh-7 resulted in secretion of OPN into the culture medium.Transfer of OPN conditioned media to na ve Huh-7 and HepG2 cells resulted in significant cell growth suggesting that all OPN variants can modulate cell proliferation in a paracrine manner.Furthermore the OPN mediated increase in cellular proliferation was dependent on CD44 as only CD44 positive cell lines responded to OPN conditioned media while siRNA knockdown of CD44 blocked the proliferative effect.OPN expression also increased the proliferation of Huh-7 cells in a subcutaneous nude mouse tumour model,with Huh-7 cells expressing OPN-A showing the greatest proliferative effect.CONCLUSION:This study demonstrates that OPN plays a significant role in the proliferation of HCC through interaction with the cell surface receptor CD44.Modulation of this interaction could represent a novel strategy for the control of HCC.Renee J Phillips Karla J Helbig Kylie H Van der Hoek Devanshi Seth Michael R Beard 2012World Journal of Gastroenterology2012,18,26:12
10焦炭特性及其在高炉下部的变化过程显示文摘气化、石墨化和溶解是影响焦炭从高炉软熔带至炉缸间行为的三个主要过程。过去几年在一些专题项目中对这些过程进行了研究。简要叙述并讨论了这些过程的相互作用及其与焦炭特性的关系。对焦炭的气化反应进行了实验室测试研究,用以评价高炉条件下焦炭的特性。用高炉条件下的气化测试装置测试了几种焦炭试样,考查的质量指标包括反应性、结构变化和强度等。用实际尺寸的焦炭块对块状焦炭试样的高温行为进行了评估,将不同种类的焦炭试样加热到2 000℃,以鉴别其在高温下的行为。高温下焦炭将发生石墨化,对高温反应后的强度进行了评定,并作了显微观察,发现了一些现象和组织结构的变化。焦炭与液态渣铁相互作用的研究结果对焦炭在高炉下部的行为有了更好的理解。通过试验研究了焦炭抗液态铁水溶解的性能,对入炉前的焦炭和经高温反应的焦炭分别进行了试验。分析讨论了焦炭的抗气化、抗石墨化和抗铁水溶解性能与其结构、化学成分和强度的关系。B van der Velden C J Atkinson T Bakker J R H Stuurwold G J Tijhuis 徐万仁 2014世界钢铁2014,,2:11
11Inflammatory bowel disease serology in Asia and the West显示文摘AIM:To study serological antibodies in Caucasians and Asians,in health and inflammatory bowel disease(IBD),in Australia and Hong Kong(HK).METHODS:Anti-glycan antibodies[anti-chitobioside(ACCA),anti-laminaribioside(ALCA)],and anti-mannobioside(AMCA),anti-Saccharomyces cervisiae(gASCA);and atypical perinuclear anti-neutrophil cytoplasmic antibody(pANCA)were tested in IBD patients,their unaffected relatives,and healthy controls in Australia and HK(China).Antibody status(positive or negative)and titre was compared between subjects of different geography,ethnicity and disease state.RESULTS:Ninety subjects were evaluated:21 Crohn’s disease(CD),32 ulcerative colitis(UC),29 healthy controls,and 8 IBD patient relatives.Forty eight subjects were Australian(29 Caucasian and 19 ethnic Han Chinese)and 42 were from HK(all Han Chinese).Caucasian CD patients had a significantly higher antibody prevalence of gASCA(67%vs 3%,P<0.001),ALCA(44%vs 6%,P=0.005),and AMCA(67%vs 15%,P=0.002),whereas HK CD patients had a higher prevalence of only AMCA(58%vs 25%,P=0.035),when compared with UC and healthy subjects in both countries.Caucasian CD had significantly higher gASCA prevalence(67%vs 0%,P<0.001)and titre(median59 vs 9,P=0.002)than HK CD patients.Prevalence and titres of ALCA,ACCA and AMCA did not differ between CD in the two countries.Presence of at least one antibody was higher in Caucasian than HK CD patients(100%vs 58%,P=0.045).pANCA did not differ between countries or ethnicity.CONCLUSION:Serologic CD responses differ between HK Asian and Australian Caucasian patients.Different genetic,environmental or disease pathogenic factors may account for these differences.Lani Prideaux Michael A Kamm Peter De Cruz Daniel R van Langenberg Siew C Ng Iris Dotan 2013World Journal of Gastroenterology2013,19,37:10
12Bone morphogenetic protein-2 is a negative regulator of hepatocyte proliferation downregulated in the regenerating liver显示文摘AIM: To characterize the expression and dynamic changes of bone morphogenetic protein (BMP)-2 in hepatocytes in the regenerating liver in rats after partial hepatectomy (PH), and examine the effects of BMP-2 on proliferation of human Huh7 hepatoma cells. METHODS: Fifty-four adult male Wistar rats were randomly divided into three groups: A normal control (NC) group, a partial hepatectomized (PH) group and a sham operated (SO) group. To study the effect of liver regeneration on BMP-2 expression, rats were sacrificed before and at different time points after PH or the sham intervention (6, 12, 24 and 48 h). For each time point, six rats were used in parallel. Expression and distribution of BMP-2 protein were determined in regenerating liver tissue by Western blot analysis and immunohistochemistry. Effects of BMP-2 on cell proliferation of human Huh7 hepatoma cell line were assessed using an MTT assay.RESULTS: In the normal liver strong BMP-2 expression was observed around the central and portal veins. The expression of BMP-2 decreased rapidly as measured by both immunohistochemistry and Western blot analysis. This decrease was at a maximum of 3.22 fold after 12 h and returned to normal levels at 48 h after PH. No significant changes in BMP-2 immunoreactivity were observed in the SO group. BMP-2 inhibited serum induced Huh7 cell proliferation.CONCLUSION: BMP-2 is expressed in normal adult rat liver and negatively regulates hepatocyte proliferation. The observed down regulation of BMP-2 following partial hepatectomy suggests that such down regulation may be necessary for hepatocyte proliferation.Cui-Ping Xu Wen-Min Ji Gijs R van den Brink Maikel P Peppelenbosch 2006World Journal of Gastroenterology2006,12,47:10
13Why interleukin-10 supplementation does not work in Crohn's disease patients显示文摘Inflammatory bowel diseases (IBD) such as Crohn's disease (CD) or ulcerative colitis are chronic intestina disorders, which are on the increase in 'Westernised' countries. IBD can be caused by both genetic and environmental factors. Interleukin-10 (IL-10) is an immunoregulatory cytokine that has been identified as being involved in several diseases including IBD. Studies have shown that polymorphisms in the promoter region reduce serum levels of IL-10 and this reduction has been associated with some forms of IBD. Mouse models have shown promising results with IL-10 supplementation, as such IL-10 supplementation has been touted as being a possible alternative treatment for CD in humans. Clinical trials have shown that recombinant human IL-10 is safe and well tolerated up to a dose o 8 μg/kg. However, to date, the results of the clinica trials have been disappointing. Although CD activity was reduced as measured by the CD activity index IL-10 supplementation did not result in significantly reduced remission rates or clinical improvements when compared to placebo. This review discusses why IL-10supplementation is not effective in CD patients currently and what can be addressed to potentially make IL-10 supplementation a more viable treatment option in the future. Based on the current research we conclude that IL-10 supplementation is not a one size fits all treatment and if the correct population of patients is chosen then IL-10 supplementation could be of benefit.Gareth J Marlow Dominique van Gent Lynnette R Ferguson 2013World Journal of Gastroenterology2013,19,25:9

15正常人额面QRS电轴的年龄趋势以及对肢体导联QRS波振幅的影响显示文摘目的调查和评估正常人额面QRS电轴的年龄趋势以及对肢体导联QRS波振幅的影响。方法采集5360例(男性3614例、女性1746例,年龄范围18~84岁)正常健康人12导联心电图分为5个年龄组,计算和分析各年龄组额面QRS电轴的中位数以及肢体导联QRS波振幅的中位数和96%的正常范围上、下限。结果随年龄增长,男、女额面QRS中位数电轴一致性地逐渐向左(上)偏移大约27°(从70°偏移到43°,P<0.001)。Ⅰ和aVL导联的R波振幅随年龄增长显著增加(P<0.001),而下壁导联Ⅱ、Ⅲ和aVF的R波振幅随年龄增长显著降低(P>0.001)。肢体导联R波振幅随年龄的变化趋势与额面QRS电轴的年龄趋势相一致。结论正常人额面QRS电轴随年龄增长逐渐向左(上)偏移,呈现明确的年龄趋势。QRS电轴的生理性演变可引起肢体导联QRS波振幅呈现明显的年龄差异。显然,把一个相同的左心室肥大心电图诊断标准应用到不同年龄组人群是不合适的。吴杰 Jan A Kors Peter R Rijnbeek Gerard van Herpen 徐春芳 陆再英 2006中华心律失常学杂志2006,10,3:8

17Systematic review: The placebo effect of psychological interventions in the treatment of irritable bowel syndrome显示文摘AIM To determine the placebo response rate associated with different types of placebo interventions used in psychological intervention studies for irritable bowel syndrome. METHODS Randomized controlled trials comparing psychological interventions(stress management/relaxation therapy(cognitive) behavioral therapy, short-term psychodynamic therapy, and hypnotherapy) for the treatment of adult patients with irritable bowel syndrome(IBS) diagnosed with the Manning or Rome criteria with an adequate placebo control treatment and reporting data on IBS symptom severity were identified by searching Pub Med, Embase, the Cochrane Library, CINAHL and Psyc INFO databases. Full-text articles that were written in English and published between 1966 and February 2016 in peer-reviewed journals were selected for the present review. Placebo interventions were considered to be adequate if the number of sessions and the amount of time spent with the therapist were the same as in the active treatment. The placebo response rate(PRR) was computed for IBS symptom severity(primary outcome measure) as well as for anxiety, depression and quality of life(secondary outcome measures). RESULTS Six studies, with a total of 555 patients met the inclusion criteria. Four studies used an educational intervention, whereas two studies used a form of supportive therapy as the placebo intervention. The PRR for IBS symptom severity ranged from 25% to 59%, with a pooled mean of 41.4%. The relative PRR for the secondary outcome measures ranged from 0% to 267% for anxiety, 6% to 52% for depression 20% to 125% for quality of life. The PRR associated with pharmacological treatments, treatment with dietary bran and complementary medicine ranged from 37.5% to 47%. Contrary to our expectations, the PRR in studies on psychological interventions was comparable to that in studies on pharmacological, dietary and alternative medical interventions.CONCLUSION The PRR is probably determined to a larger extent by patient-related factors, such as expectations and desire for the treatment to be effective, than the content of the placebo intervention.Carla E Flik Laura Bakker Wijnand Laan Yanda R van Rood André JPM Smout Niek J de Wit 2017World Journal of Gastroenterology2017,23,12:7
18Near-infrared fluorescence imaging of a solitary fibrous tumor of the pancreas using methylene blue显示文摘A 67-year-old female presented with unexplained abdominal pain. A contrast-enhanced computed tomography scan of the abdomen incidentally revealed a mass in the uncinate process of the pancreas. This mass was resected and based on histopathological findings, diagnosed as a solitary fibrous tumor (SFT) of the pancreas. A SFT is an extremely rare benign mesenchymal tumor that in 65% of cases affects the visceral pleura but can also affect extra-pleural sites. The intraoperative demarcation of pancreatic tumors, such as SFTs, can bechallenging. In this report, the first clear intraoperative identification of a SFT of the pancreas in a human was shown using near-infrared fluorescence and methylene blue.Joost R van der Vorst Alexander L Vahrmeijer Merlijn Hutteman Tjalling Bosse Vincent THBM Smit Cornelis JH van de Velde John V Frangioni Bert A Bonsing 2012World Journal of Gastrointestinal Surgery2012,4,7:7
19Challenges in diagnosing adhesive small bowel obstruction显示文摘Adhesive small bowel obstruction(ASBO)is the most frequently encountered surgical disorder of the small intestine.Up to 80%of ASBO cases resolve spontaneously and do not require invasive treatment.It is important to identify such patients that will benefit from conservative treatment in order to prevent unnecessarily exposing them to the risks associated with surgical intervention,such as morbidity and further adhesion formation.For the remaining ASBO patients,timely surgical intervention is necessary to prevent small bowel strangulation,which may cause intestinal ischemia and bowel necrosis.While early identification of these patients is key to decreasing ASBO-related morbidity and mortality,the non-specific signs and laboratory findings upon clinic presentation limit timely diagnosis and implementation of appropriate clinical management.Combining the clinical presentation findings with those from other diagnostic imaging modalities,such as abdominal X-ray,computed tomography-scan and water-soluble contrast studies,will improve diagnosis of ASBO and help clinicians to better evaluate the potential of conservative management as a safe strategy for a particular patient.Nonetheless,patients who present with moderate findings by all these approaches continue to represent a challenge.A new diagnostic strategy is urgently needed to further improve our ability to identify early signs of strangulated bowel,and this diagnostic modality should be able to indicate when surgical management is required.A number of potential serum markers have been proposed for this purpose,including intestinal fatty acid binding protein andα-glutathione S transferase.On-going research is attempting to clearly define their diagnostic utility and to optimize their potential role in determining which patients should be managed surgically.Thijs R van Oudheusden Bart AC Aerts Ignace HJT de Hingh Misha DP Luyer 2013World Journal of Gastroenterology2013,19,43:7
