7Systematic review of prognostic importance of extramuralvenous invasion in rectal cancer显示文摘AIM: To systematically review the survival outcomes relating to extramural venous invasion in rectal cancer.METHODS: A systematic review was conducted using PRISMA guidelines. An electronic search was carried out using MEDLINE, EMBASE, CINAHL, Cochrane library databases, Google scholar and Pub Med until October 2014. Search terms were used in combination to yield articles on extramural venous invasion in rectal cancer. Outcome measures included prevalence and 5-year survival rates. These were graphically displayed using Forest plots. Statistical analysis of the data was carried out.RESULTS: Fourteen studies reported the prevalence of extramural venous invasion(EMVI) positive patients. Prevalence ranged from 9%-61%. The pooled prevalence of EMVI positivity was 26% [Random effects: Event rate 0.26(0.18, 0.36)]. Most studies showed that EMVI related to worse oncological outcomes. The pooled overall survival was 39.5% [Random effects: Event rate 0.395(0.29, 0.51)].CONCLUSION: Historically, there has been huge variation in the prevalence of EMVI through inconsistent reporting. However the presence of EMVI clearly leads to worse survival outcomes. As detection rates become more consistent, EMVI may be considered as part of risk-stratification in rectal cancer. Standardised histopathological definitions and the use of magnetic resonance imaging to identify EMVI will improve detection rates in the future.Manish Chand Muhammed RS Siddiqui Ian Swift Gina Brown 2016World Journal of Gastroenterology2016,22,4:15

10Effects of raster resolution on landslide susceptibility mapping:A case study of Shenzhen显示文摘Resolution has been playing a significant role in landslide susceptibility mapping and hazard assessment.Based on geographical information system(GIS) and information model,the effects of raster resolution on landslide susceptibility mapping are studied in a central area of Shenzhen,China.Eight factors are selected to calculate landslide susceptibility with eleven groups of different resolutions(5 to 190 m).It has been found that a finer resolution does not necessarily lead to a higher accuracy of landslide susceptibility mappings,while the result of 90 m-resolution has the best accuracy and the 150 m-resolution has the worst one.The accuracy curve is in a shape of 'W' along with resolution decreasing:1) The accuracy decreases from 5 to 70 m;2) and then the best accuracy appears at 90 m,which is almost the same as the mean size of landslides in study area;3) the accuracy decreases again from 110 to 150 m;4) and finally the accuracy increases from 150 to 190 m.The sensitivity analysis indicates that the effects of raster resolution are mainly caused by the resolution impact on landform parameter derivation,while factors like geology and human activity are very insensitive to resolutions.A further study shows that in flat,ridge,and slope foot terrains,the susceptibility mapping result is sensitive to resolution,but in the sloping surface area the sensitivity is much less sensitive to resolution.At last,by choosing study areas with different sizes,it has also been found that the optimal resolutions are variable due to size of study area.But the study area is larger than a threshold,which is 135 km2 in this study,and the optimal resolution is almost fixed.TIAN Yuan,XIAO ChenChao,LIU Yu & WU Lun Institute of RS and GIS,Peking University,Beijing 100871,China 2008Science China(Technological Sciences)2008,51,S2:8
11Systematic review of emergent laparoscopic colorectal surgery for benign and malignant disease显示文摘Laparoscopic surgery has become well established in the management of both and malignant colorectal disease.The last decade has seen increasing numbers of surgeons trained to a high standard in minimallyinvasive surgery.However there has not been the same enthusiasm for the use of laparoscopy in emergency colorectal surgery.There is a perception that emergent surgery is technically more difficult and may lead to worse outcomes.The present review aims to provide a comprehensive and critical appraisal of the available literature on the use of laparoscopic colorectal surgery(LCS)in the emergency setting.The literature is broadly divided by the underlying pathology;that is,inflammatory bowel disease,diverticulitis and malignant obstruction.There were no randomized trials and the majority of the studies were case-matched series or comparative studies.The overall trend was that LCS is associated with shorter hospital stay,par or fewer complications but an increased operating time.Emergency LCS can be safely undertaken for both benign and malignant disease providing there is appropriate patient selection,the surgeon is adequately experienced and there are sufficient resources to allow for a potentially more complex operation.Manish Chand Muhammed RS Siddiqui Ashish Gupta Shahnawaz Rasheed Paris Tekkis Amjad Parvaiz Alex H Mirnezami Tahseen Qureshi 2014World Journal of Gastroenterology2014,20,45:7

13Defining response to radiotherapy in rectal cancer using magnetic resonance imaging and histopathological scales显示文摘AIM To define good and poor regression using pathology and magnetic resonance imaging(MRI) regression scales after neo-adjuvant chemotherapy for rectal cancer.METHODS A systematic review was performed on all studies up to December 2015, without language restriction, t h a t w e r e i d e n t i f i e d f r o m M E D L I N E, C o c h r a n e Controlled Trials Register(1960-2015), and EMBASE(1991-2015). Searches were performed of article bibliographies and conference abstracts. MeS H and text words used included 'tumour regression', 'mr TRG', 'poor response' and 'colorectal cancers'. Clinical studies using either MRI or histopathological tumour regression grade(TRG) scales to define good and poor responders were included in relation to outcomes [local recurrence(LR), distant recurrence(DR), disease-free survival(DFS), and overall survival(OS)]. There was no age restriction or stage of cancer restriction for patient inclusion. Data were extracted by two authors working independently and using pre-defined outcome measures.RESULTS Quantitative data(prevalence) were extracted and analysed according to meta-analytical techniques using comprehensive meta-analysis. Qualitative data(LR, DR, DFS and OS) were presented as ranges. The overall proportion of poor responders after neo-adjuvant chemoradiotherapy(CRT) was 37.7%(95%CI: 30.1-45.8). There were 19 different reported histopathological scales and one MRI regression scale(mrT RG). Clinical studies used nine and six histopathological scales for poor and good responders, respectively. All studies using MRI to define good and poor response used one scale. The most common histopathological definition for good response was the Mandard grades 1 and 2 or Dworak grades 3 and 4; Mandard 3, 4 and 5 and Dworak 0, 1 and 2 were used for poor response. For histopathological grades, the 5-year outcomes for poor responders were LR 3.4%-4.3%, DR 14.3%-20.3%, DFS 61.7%-68.1% and OS 60.7-69.1. Good pathological response 5-year outcomes were LR 0%-1.8%, DR 0%-11.6%, DFS 78.4%-86.7%, and OS 77.4%-88.2%. A poor response on MRI(mr TRG 4,5) resulted in 5-year LR 4%-29%, DR 9%, DFS 31%-59% and OS 27%-68%. The 5-year outcomes with a good response on MRI(mrT RG 1,2 and 3) were LR 1%-14%, DR 3%, DFS 64%-83% and OS 72%-90%.CONCLUSION For histopathology regression assessment, Mandard 1, 2/Dworak 3, 4 should be used for good response and Mandard 3, 4, 5/Dworak 0, 1, 2 for poor response. MRI indicates good and poor response by mr TRG1-3 and mrT RG4-5, respectively.Muhammed RS Siddiqui Jemma Bhoday Nicholas J Battersby Manish Chand Nicholas P West Al-Mutaz Abulafi Paris P Tekkis Gina Brown 2016World Journal of Gastroenterology2016,22,37:6
14Investigating spatial distribution of tourist attractions’inlinks: A case study of three mountains显示文摘In hyperlink analysis,most researchers focus on interpreting hyperlink counts,they seldom concern themselves enough about the significance of spatial distribution of hyperlinks.In this paper,we argue that not only can the inlink count to a tourist attraction’s official website reflect its attractiveness,but also the spatial distribution of its inlinks can reflect the distribution of its tourist source markets.Three mountains in Anhui Province,China,are chosen for the case study.Firstly,the correlation between the spatial distributions of an attraction’s tourist source markets and its official website’s inlinks is investigated.Secondly,the tourism indexes such as the spatial concentration index(SCI)and the attraction radius(AR),which are calculated by inlinks,are compared to the real indexes based on tourist sources.Last,the detailed discussion and analysis are presented and an improved model,which is used to calculate the distribution of inlinks,is proposed.ZHANG Yi 1,QI LiNa 2,YANG AnRan 1,SHI Lei 1 & XU Li 1 1 Institute of RS and GIS,Peking University,Beijing 100871,China 2 Center for Recreation and Tourism Research,Peking University,Beijing 100871,China 2010Science China(Technological Sciences)2010,53,S1:5
15Subcurative radiation significantly increases cell proliferation, invasion, and migration of primary glioblastoma multiforme in vivo显示文摘Tumor cell proliferation, infiltration, migration, and neovascularization are known causes of treatment resistance in glioblastoma multiforme(GBM). The purpose of this study was to determine the effect of radiation on the growth characteristics of primary human GBM developed in a nude rat. Primary GBM cells grown from explanted GBM tissues were implanted orthotopically in nude rats. Tumor growth was confirmed by magnetic resonance imaging on day 77(baseline) after implantation. The rats underwent irradiation to a dose of 50 Gy delivered subcuratively on day 84 postimplantation(n = 8), or underwent no radiation(n = 8). Brain tissues were obtained on day 112(nonirradiated) or day 133(irradiated). Immunohistochemistry was performed to determine tumor cell proliferation(Ki-67) and to assess the expression of infiltration marker(matrix metalloproteinase-2, MMP-2) and cell migration marker(CD44). Tumor neovascularization was assessed by microvessel density using von-Willebrand factor(vWF) staining. Magnetic resonance imaging showed well-developed, infiltrative tumors in 11 weeks postimplantation. The proportion of Ki-67-positive cells in tumors undergoing radiation was(71 ± 15)% compared with(25 ± 12)% in the nonirradiated group(P = 0.02). The number of MMP-2-positive areas and proportion of CD44-positive cells were also high in tumors receiving radiation, indicating great invasion and infiltration. Microvessel density analysis did not show a significant difference between nonirradiated and irradiated tumors. Taken together, we found that subcurative radiation significantly increased proliferation, invasion, and migration of primary GBM. Our study provides insights into possible mechanisms of treatment resistance following radiation therapy for GBM.Adarsh Shankar Sanath Kumar Asm Iskander Nadimpalli RS Varma Branislava Janic Ana deCarvalho Tom Mikkelsen Joseph A Frank Meser M Ali Robert A Knight Stephen Brown Ali S Arbab 2014Chinese Journal of Cancer2014,33,3:5
16Integral ear elimination and virtual point-based updating algorithms for constrained Delaunay TIN显示文摘Constrained Delaunay Triangular Irregular Networks (CD-TIN),a kind of special data structure,have many practical applications in Geoinformatics,especially in the representation of linear constrained triangulation for DTM and DSM,such as in digital city and digital mine. Past researches on D-TIN mainly focused on point in-sertion and deletion without consideration of constraint,and that on CD-TIN usu-ally paid more attention to the insertion algorithms for points and edges,but little to the deletion algorithms. The presented algorithms are far insufficient for the dy-namic updating of CD-TIN. In this paper,the constraint edge in CD-TIN is consid-ered to be any set of broken lines,i.e.,polygon edges,broken lines and simple segments. The constraint edge may be composed of one or more constraint seg-ments,and it is allowed to be in any form: Open or close,intersection or self-in-tersection. By improving to present insertion and deletion algorithms for D-TIN,two new algorithms for CD-TIN updating are presented. According to the polymorphism of the constraints in CD-TIN,virtual point is adopted to represent the crossing node between constraint edges when a constraint edge is inserted in CD-TIN. Two new algorithms named as Integral Ear Elimination (IEE) and Influence Domain Retrian-gulation for Virtual Point (IDRVP) are presented,the former is for constraint point deletion,while the later is for the insertion and deletion of constraint edge. The principle of IDRVP is that to divide the influence domain of a virtual point into some parts by the constraint-keeping edges,and to retriangulate each part of the influ-ence domain individually referring to the constraint visible property and constraint empty circle (CEC) criterion. Finally,a prototype system is developed with VC++,one case on the integration of 3D terrain and buildings is demonstrated to test the correctness of new algorithms. It shows that the new algorithms are effective for the updating of CD-TIN.WU LiXin1,2,WANG YanBing2,3 & SHI WenZhong2,4 1 Institute for Geo-informatics & Digital Mine Research,Northeastern University,Shenyang 110004,China 2 Institute for GIS/RS/GPS & Subsidence Engineering Research,China University of Mining & Technology,Beijing 100085,China 3 Laboratory of 3D Information Acquisition & Application,Capital Normal University,Beijing 100037,China 4 Center for Advanced GIS Research,LSGI,Polytechnic University Hong Kong,Hong Kong,China 2008Science China(Technological Sciences)2008,51,S1:5
17A method of quantitatively calculating amount of allochthonous organic carbon in lake sediments显示文摘TOTAL organic matter(TOM) or total organic carbon(TOC) is often treated as an importantindicator of lake environment. As a matter of fact, TOC is of multi-origin, and can simply bedivided into two parts: autochthonous and allochthonous organic carbon. The autochthonousorganic carbon is mainly controlled by the production of the plankton of lake itse1f; and the al-lochthonous one by climate and environment in the catchment area, e. g. more precipitationand runoff and densely developed vegetation will give rise to more allochthonous organic com-Qian, JL Wang, SM Xue, B Chen, RS Ke, SZ 1997Chinese Science Bulletin1997,42,21:5
