1Probiotic effects on intestinal fermentation patterns in patients with irritable bowel syndrome显示文摘AIM: To determine whether Lactobacillus casei strain Shirota (Yakult ) can alter small intestinal bacterial overgrowth (SIBO), as tested by the lactulose breath test, and whether this is associated with changes in symptoms in irritable bowel syndrome (IBS). METHODS: 18 patients with IBS (Rome Ⅱ criteria), who showed an early rise in breath hydrogen with lactulose (ERBHAL), consumed 65 mL of Yakult daily for 6 wk. Lactulose breath test was repeated at the end of the treatment period. Symptoms were recorded daily using a 10 cm visual analogue scale. RESULTS: 14 patients completed the study, 9 (64%) had reversal of ERBHAL, with the median time of f irst rise in breath hydrogen increasing from 45 to 75 min (P = 0.03). There was no signifi cant improvement in the symptom score with probiotic therapy, except for wind (P=0.04). Patients commencing with at least moderate symptoms and who no longer had ERBHAL at the end of treatment, showed improvement in the overall symptoms scores [median fi nal score 5.3 (IQR3.9-5.9), 55% reduction; n=6] to a greater extent than those who had had persisting ERBHAL [final score 6.9 (5.0-7.0), 12% reduction; n = 5; P = 0.18]. CONCLUSION: Yakult is effective in altering fermentation patterns in the small bowel, consistent with reducing SIBO. The loss of ERBHAL was associated with reduced symptoms. The true interpretation of these fi ndings awaits a randomised, controlled trial.Jacqueline S Barrett Kim EK Canale Richard B Gearry Peter M Irving Peter R Gibson 2008World Journal of Gastroenterology2008,14,32:16

3考古学中的聚落形态显示文摘西方考古学中聚落考古的概念自上世纪80年代由张光直首先引入中国,已经有20多年的历史。在这20多年中,聚落考古学在中国有了很大的发展,大家对聚落考古的理论、方法和技术已经比较熟悉,在实践方面也取得了相当大的成就。可以说,聚落考古学当前已经与地层学、类型学一样成为了中国考古学的基本方法之一。欧文·劳斯这篇与张光直的名篇同名的文章都是发表于1972年。在那个年代,西方考古学中的聚落考古研究正是方兴未艾。虽然同为全面介绍聚落考古学的论文,但劳斯在概念的理解与运用上与张光直却有很大的不同。张光直主要侧重聚落考古在社会关系研究方面的作用,与威利和特里格一样认为聚落考古就是运用考古资料进行社会关系的研究。而劳斯则从另一个角度出发来看待聚落形态概念在考古研究中的作用,受系统论的影响较大。将这篇文章与以往介绍到国内的聚落考古方面的文献结合阅读,会对西方聚落考古学有一个更加全面的认识。劳斯认为一个人群的生活系由三个系统所组成,即生态系统、文化系统和社会系统。生态系统反映了对环境的适应和资源的利用,文化系统系指人们的日常行为,社会系统则是指各类组织性的群体、机构和制度。在针对过去人类生活的全部问题中,聚落形态的概念(本文作者用的是残存聚落形态,指出了聚落形态作为考古遗存和研究对象的特点,认为它是由人类行为点的网络和每个点位的行为组合所构成)在与此三个系统有关的研究中特别有用。运用聚落形态方法,不仅可以研究文化的社会关系方面,也可以研究文化的生态和行为方面。在实践中,可以从这三类系统所拥有的亚系统入手,寻找证据以重建以上三类系统,复原人类的生活。他将聚落形态分为三个类型,即分散型、集中型和共生型。其中最有启发性的是维生和专职共生形态,它为研究文明化问题提供了一个十分重要的概念工具。另外,从聚落形态的概念出发,劳斯还探讨了文明与城市化的区别及其在考古学实践上的价值,也颇有意义。欧文·劳斯(Irving Rouse) 潘艳(译) 陈洪波(译) 陈淳(校) 2007南方文物2007,,3:10
4从660 km边界地形推断地球不连续的化学分层显示文摘板块构造学说是固体地.球科学的基石,刻画了岩石圈的基本运动学特征,而地幔对流理论则为理解板块运动提供了动力学基础。然而长期以来,地幔对流模式的研究一直存在巨大的争议,分玻主要集中于全见幔对流和上下他幔分层对流两个模式。近年来还有一些学者提出了地混合对流模式的猜想,即一些区域地幔分层对流、其他区域上下他做整体对流。已有研究表明,温度异帯及化学异常均可造成大尺度(1000km)和中等尺度(100km)的间斷面起伏。张宝华 Wu W Ni S Irving J C 2019矿物岩石地球化学通报2019,38,3:6

6伴肠化的阑尾或盲肠子宫内膜异位症:酷似阑尾黏液性肿瘤变显示文摘典型的阑尾或盲肠子宫内膜异位症的诊断通常并不困难,但一些伴有肠上皮化生的罕见病例可能误诊为阑尾黏液肿瘤。作者描述6例阑尾或盲肠伴有肠化的子宫内膜异位症,其无论在大体或镜下,都酷似阑尾黏液肿瘤。这些病例阑尾壁显著增粗,弹力变性,阑尾变形扭曲,阑尾腔完全闭塞。所有病例均可见典型的异位子宫内膜与大量伴肠化的内膜腺体共存。Misdraji J Lauwers G Y Irving J A 陈婷婷 陈远钦 余英豪 2014临床与实验病理学杂志2014,30,8:6
7美国密西西比河三角洲湿地流失的原因及修复措施显示文摘密西西比河三角洲是世界上最大的三角洲,包括1.2万km。海岸湿地,是一个重要的生态区。然而,近年来密西西比河三角洲湿地不断流失,从20世纪30年代至90年代,已经流失了3950km2,流失速率达65~91km2/a,对沿岸城市的生态环境和经济发展造成了巨大的负面影响,专家预测,到2050年湿地流失面积将达到1833km2。造成湿地流失的主要原因有三角洲循环、相对海平面上升、海水入侵、地面沉降、大规模的冬季风暴和飓风袭击、啮齿类食苹动物对湿地的破坏及履带车的使用等。为减缓湿地流失速度,恢复湿地生态环境,可采取分流河道引入淡水、种植湿地植物、补充泥沙及恢复障壁岛等措施。丁喜桂 Irving A Mendelssohn 王吉松 2011海洋地质前沿2011,27,2:5

9Endoscopic treatment of Barrett's esophagus:From metaplasia to intramucosal carcinoma显示文摘The annual incidence of adenocarcinoma arising from Barrett’s esophagus (BE) is approximately 0.5%. Through a process of gradual transformation from lowgrade dysplasia to high-grade dysplasia (HGD), adenocarcinoma can develop in the setting of BE. The clinical importance of appropriate identifi cation and treatment of BE in its various stages, from intestinal metaplasia to intramucosal carcinoma (IMC) hinges on the dramatically different prognostic status between early neoplasia and more advanced stages. Once a patient has symptoms of adenocarcinoma, there is usually locally advanced disease with an approximate 5-year survival rate of about 20%. Esophagectomy has been the gold standard treatment for BE with HGD, due to the suspected risk of harboring occult invasive carcinoma, which was traditionally estimated to be as high as 40%. In recent years, the paradigm of BE early neoplasia management has recently evolved, and endoscopic therapies (endoscopic mucosal resection, radiofrequency ablation, and cryotherapy) have entered the clinical forefront as acceptable non-surgical alternatives for HGD and IMC. The goal of endoscopic therapy for HGD or IMC is to ablateall BE epithelium (both dysplastic and non-dysplastic) due to risk of synchronous/metachronous lesion development in the remaining BE segment.Jennifer Chennat Irving Waxman 2010World Journal of Gastroenterology2010,16,30:4

12Risk-adjustment in hepatobiliarypancreatic surgery显示文摘AIM: The present study evaluates the performance of the POSSUM, the American Society of Anesthetists (ASA),APACHE and Childs classification in predicting mortality and morbidity in hepatopancreaticobiliary (HPB) surgery.We describe especially the limitations and advantages of risk in stratifying the patients.METHODS: We investigated 177 randomly chosen patients undergoing eledive complex HPB surgery in a single institution with a total of 71 pre-operative and intra-operative risk factors.Primary endpoint was in-hospital mortality and morbidity.Ordered logistic regression analysis was used to identify individual predictors of operative morbidity and mortality.RESULTS: The operative mortality in the series was 3.95% .This compared well with the p-POSSUM and APACHE predicted mortality of 4.31% and 4.29% respectively. Postoperative complications amounted to 45% with 24 (13.6%)patients having a major adverse event. On multivariate analysis the pre-operative POSSUM physiological score (OR = 1.18,P = 0.009) was superior in predicting complications compared to the ASA (P = 0.108), APACHE (P = 0.117)or Childs classification (P = 0.136). In addition, serum sodium, creatinine, international normalized ratio (INR),pulse rate, and intra-operative blood loss were independent risk factors. A combination of the POSSUM variables and INR offered the optimal combination of risk factors for risk prognostication in HPB surgery.CONCLUSION: Morbidity for elective HPB surgery can be accurately predicted and applied in everyday surgical practice as an adjunct in the process of informed consent and for effective allocation of resources for intensive and high-dependency care facilities.Hemant M Kocher Paris P Tekkis Palepu Gopal Ameet G Patel Simon Cottam Irving S Benjamin 2005World Journal of Gastroenterology2005,11,16:3

20Recurrent missense mutation of GDF5 (p.R438L) causes proximal symphalangism in a British family显示文摘Proximal symphalangism(SYM1B)(OMIM 615298) is an autosomal dominant developmental disorder affecting joint fusion. It is characterized by variable fusions of the proximal interphalangeal joints of the hands,typically of the ring and little finger,with the thumb typically being spared. SYM1 is frequently associated with coalition of tarsal bones and conductive hearing loss. Molecular studies have identified two possible genetic aetiologies for this syndrome,NOG and GDF5. We herein present a British caucasian family with SYM1 B caused by a mutation of the GDF5 gene. A mother and her three children presented to the orthopaedic outpatient department predominantly for feet related problems. All patients had multiple tarsal coalitions and hand involvement in the form of either brachydactyly or symphalangism of the proximal and middle phalanx of the little fingers. Genetic testing in the eldest child and his mother identified a heterozygous missense mutation in GDF5 c.1313G>T(p.R438L),thereby establishing SYM1 B as the cause of the orthopaedic problems in this family. There were no mutations identified in the NOG gene. This report highlights the importance of thorough history taking,including a three generation family history,and detailed clinical examination of children with fixed planovalgus feet and other family members to detect rare skeletal dysplasia conditions causing pain and deformity,and provides details of the spectrum of problems associated with SYM1 B.Andreas Leonidou Melita Irving Simon Holden Marcos Katchburian 2016World Journal of Orthopedics2016,7,12:2
