3Helicobacter pylori and extragastric diseases: A review显示文摘Helicobacter pylori(H. pylori) infection is very common and affects approximately half of the world population. It causes gastric diseases, but some authors have reported an association of H. pylori infection with other systemic manifestations beginning in 1994. The list of potential effects of H. pylori outside the stomach includes a number of extragastric manifestations and we focused on neurological, dermatological, hematologic, ocular, cardiovascular, metabolic, allergic, and hepatobiliary diseases. This review discusses these important reported manifestations that are not related to the gastrointestinal tract.Antonietta Gerarda Gravina Rocco Maurizio Zagari Cristiana De Musis Lorenzo Romano Carmelina Loguercio Marco Romano 2018World Journal of Gastroenterology2018,24,29:90
4Pathogenesis and clinical management of Helicobacter pylori gastric infection显示文摘Helicobacter pylori(H.pylori)is a gram-negative bacterium that infects approximately 4.4 billion individuals worldwide.However,its prevalence varies among different geographic areas,and is influenced by several factors.The infection can be acquired by means of oral-oral or fecal-oral transmission,and the pathogen possesses various mechanisms that improve its capacity of mobility,adherence and manipulation of the gastric microenvironment,making possible the colonization of an organ with a highly acidic lumen.In addition,H.pylori presents a large variety of virulence factors that improve its pathogenicity,of which we highlight cytotoxin associated antigen A,vacuolating cytotoxin,duodenal ulcer promoting gene A protein,outer inflammatory protein and gamma-glutamyl transpeptidase.The host immune system,mainly by means of a Th1-polarized response,also plays a crucial role in the infection course.Although most H.pylori-positive individuals remain asymptomatic,the infection predisposes the development of various clinical conditions as peptic ulcers,gastric adenocarcinomas and mucosa-associated lymphoid tissue lymphomas.Invasive and non-invasive diagnostic methods,each of them with their related advantages and limitations,have been applied in H.pylori detection.Moreover,bacterial resistance to antimicrobial therapy is a major challenge in the treatment of this infection,and new therapy alternatives are being tested to improve H.pylori eradication.Last but not least,the development of effective vaccines against H.pylori infection have been the aim of several research studies.Breno Bittencourt de Brito Filipe Ant?nio Fran?a da Silva Aline Silva Soares Vinícius Afonso Pereira Maria Luísa Cordeiro Santos Mariana Miranda Sampaio Pedro Henrique Moreira Neves Fabrício Freire de Melo 2019World Journal of Gastroenterology2019,25,37:84
5Measurements of dihadron correlations relative to the event plane in Au+Au collisions at√^(S)NN=200 GeV显示文摘Dihadron azimuthal correlations containing a high transverse momentum(pr)trigger particle are sensit-ive to the properties of the nuclear medium created at RHIC through the strong interactions occurring between the traversing parton and the medium,ie.jet-quenching.Previous measurements revealed a strong modification to di-hadron azimuthal correlations in Au+Au collisions with respect to ptp and d+Au collisions.The modification in-creases with the collision centrality,suggesting a path-length or energy density dependence to the je-quenching ef-fect.This paper reports STAR measurements of dihadron azimuthal correlations in mid-central(20%-60%)Au+Au collisions at√^(S)NN=200 GeV as a function of the trigger particle's azimuthal angle relative to the event plane,Ф_(s)=|Ф_(t)-ψ_(Ep)|.The azimuthal correlation is studied as a function of both the trigger and associated particle pr.The subtractions of the combinatorial background and anisotropic flow,assuming Zero Yield At Minimum(ZYAM),are described.The correlation results are first discussed with subtraction of the even harmonic(elliptic and quadrangu-lar)flow backgrounds.The away-side correlation is strongly modifed,and the modification varies withФ_(s),with a double-peak structure for out-of-plane trigger particles.The near-side ridge(long range pseudo-rapidity△_(η)correla-tion)appears to drop with increasingФ_(s)while the jet-like component remains approximately constant.The correla-tion functions are further studied with the subtraction of odd harmonic triangular flow background arising from fluc-tuations.It is found that the triangular flow,while responsible for the majority of the amplitudes,is not sufficient to explain theφs-dependence of the ridge or the away-side double-peak structure.The dropping ridge withФ_(s)could be attributed to aФ_(s)-dependent lliptie anisotropy;however,the physics mechanism of the ridge remains an open ques-tion.Even with aФ_(s)-dependent elliptic flow,the away-side correlation structure is robust.These results,with extens-ive systematic studies of the dihadron correlations as a function ofФ_(s),trigger and associated particle pT,and the pseudo-rapidity range△_(η),should provide stringent inputs to help understand the underlying physics mechanisms of jet-medium interactions in high energy nuclear collisions.H.Agakishiev M.M.Aggarwal Z.Ahammed A.V.Alakhverdyants I.Alekseev J.Alford B.D.Anderson C.D.Anson D.Arkhipkin G.S.Averichev J.Balewski

6A complete sequence and comparative analysis of a SARS-associated virus(Isolate BJ01)显示文摘The genome sequence of the Severe Acute Respiratory Syndrome (SARS)-associated virus provides essential information for the identification of pathogen(s), exploration of etiology and evolution, interpretation of transmission and pathogenesis, development of diagnostics, prevention by future vaccination, and treatment by developing new drugs. We report the complete genome sequence and comparative analysis of an isolate (BJ01) of the coronavirus that has been recognized as a pathogen for SARS. The genome is 29725 nt in size and has 11 ORFs (Open Reading Frames). It is composed of a stable region encoding an RNA-dependent RNA polymerase (composed of 2 ORFs) and a variable region representing 4 CDSs (coding sequences) for viral structural genes (the S, E, M, N proteins) and 5 PUPs (putative uncharacterized proteins). Its gene order is identical to that of other known coronaviruses. The sequence alignment with all known RNA viruses places this virus as a member in the family of Coronaviridae. Thirty putative substitutions have been identified by comparative analysis of the 5 SARS- associated virus genome sequences in GenBank. Fifteen of them lead to possible amino acid changes (non-synonymous mutations) in the proteins. Three amino acid changes, with predicted alteration of physical and chemical features, have been detected in the S protein that is postulated to beinvolved in the immunoreactions between the virus and its host. Two amino acid changes have been detected in the Mprotein, which could be related to viral envelope formation. Phylogenetic analysis suggests the possibility of non-human origin of the SARS-associated viruses but provides noevidence that they are man-made. Further efforts should focus on identifying the etiology of the SARS-associated virus and ruling out conclusively the existence of otherpossible SARS-related pathogen(s).QIN E'de ZHU Qingyu YU Man FAN Baochang CHANG Guohui SI Bingyin YANG Bao PENG Wenming JIANG Tao LIU Bohua DENG Yongqiang LIU Hong ZHANG Yu WANG Cui LI Yuquan GAN Yonghua LI Xiaoyu L Fushuang TAN Gang CAO Wuchun, YANG Ruifu Institute of Microbiology and Epidemiology, Chinese Academy of Military Medical Sciences, Beijing 100071, China WANG Jian, LI Wei, XU Zuyuan, LI Yan, WU Qingfa, LIN Wei, CHEN Weijun, TANG Lin, DENG Yajun, HAN Yujun, LI Changfeng, LEI Meng, LI Guoqing, LI Wenjie, L Hong, SHI Jianping, TONG Zongzhong, ZHANG Feng, LI Songgang, LIU Bin, LIU Siqi, DONG Wei, WANG Jun, Gane K-S Wong, YU Jun & YANG Huanming* Beijing Genomics Institute, Chinese Academy of Sciences, Beijing 101300 National Center for Genome Information, Beijing 101300, China 2003Chinese Science Bulletin2003,48,10:121
7Treatment of gastric cancer显示文摘The authors focused on the current surgical treatment of resectable gastric cancer,and significance of periand post-operative chemo or chemoradiation.Gastric cancer is the 4thmost commonly diagnosed cancer and the second leading cause of cancer death worldwide.Surgery remains the only curative therapy,while perioperative and adjuvant chemotherapy,as well as chemoradiation,can improve outcome of resectable gastric cancer with extended lymph node dissection.More than half of radically resected gastric cancer patients relapse locally or with distant metastases,or receive the diagnosis of gastric cancer when tumor is disseminated;therefore,median survival rarely exceeds12 mo,and 5-years survival is less than 10%.Cisplatin and fluoropyrimidine-based chemotherapy,with addition of trastuzumab in human epidermal growth factor receptor 2 positive patients,is the widely used treatment in stageⅣpatients fit for chemotherapy.Recent evidence supports the use of second-line chemotherapy after progression in patients with good performanceMichele Orditura Gennaro Galizia Vincenzo Sforza Valentina Gambardella Alessio Fabozzi Maria Maddalena Laterza Francesca Andreozzi Jole Ventriglia Beatrice Savastano Andrea Mabilia Eva Lieto Fortunato Ciardiello Ferdinando De Vita 2014World Journal of Gastroenterology2014,20,7:116
8Portal vein thrombosis:Insight into physiopathology,diagnosis,and treatment显示文摘Portal vein thrombosis (PVT) is a relatively common complication in patients with liver cirrhosis, but might also occur in absence of an overt liver disease. Several causes, either local or systemic, might play an important role in PVT pathogenesis. Frequently, more than one risk factor could be identified; however, occasionally no single factor is discernable. Clinical examination, laboratory investigations, and imaging are helpful to provide a quick diagnosis, as prompt treatment might greatly affect a patient's outcome. In this review, we analyze the physiopathological mechanisms of PVT development, together with the hemodynamic and functional alterations related to this condition. Moreover, we describe the principal factors most frequently involved in PVT development and the recent knowledge concerning diagnostic and therapeutic procedures. Finally, we analyze the implications of PVT in the setting of liver transplantation and its possible influence on patients' future prognoses.Francesca R Ponziani Maria A Zocco Chiara Campanale Emanuele Rinninella Annalisa Tortora Luca Di Maurizio Giuseppe Bombardieri Raimondo De Cristofaro Anna M De Gaetano Raffaele Landolfi Antonio Gasbarrini 2010World Journal of Gastroenterology2010,16,2:75
9Effect of phosphorylation of MAPK and Stat3 and expression of c-fos and c-jun proteins on hepatocarcinogenesis and their clinical significance显示文摘AIM To study the effect of phosphorylation ofMAPK and Stat3 and the expression of c-fos andc-jun proteins on hepatocellular carcinogenesisand their clinical significance.METHODS SP immunohistochemistry was usedto detect the expression of p42/44MAPK, p-Stat3,c-fos and c-jun proteins in 55 hepatocellularcarcinomas (HCC) and their surrounding livertissues.RESULTS The positive rates and expressionlevels of p42/44MAPK, p-Stat3, c-fos and c-junproteins in HCCs were significantly higher thanthose in pericarcinomatous liver tissues (PCLT).A positive correlation was observed between theexpression of p42/44MAPK and c-fos proteins, andbetween p-Stat3 and c-jun, but there was nosignificant correlation between p42/44MAPK and p-Stat3 in HCCs and their surrounding livertissues.CONCLUSION The abnormalities of Ras/Rat/MAPK and JAKs/ Stat3 cascade reaction maycontribute to malignant transformation ofhepatocytes. Hepatocytes which are positive forp42/ 44MAPK, c-fos or c-jun proteins may bepotential malignant pre-cancerous cells.Activation of MAPK and Stat3 proteins may be anearly event in hepatocellular carcinogenesis.De Yun Feng Hui Zheng Yi Tan Rui Xue Cheng Department of Pathology, Hunan Medical University, Changsha 410078, Hunan Province, China New England Biolab, MA, USA 2001World Journal of Gastroenterology2001,7,1:75

12Species Concepts as Applied to the Whitefly Bemisia tabaci Systematics:How Many Species Are There?显示文摘The worldwide distribution and extensive genetic diversity of the whitefly,Bemisia tabaci,has long been recognized.However,the levels of separation within B.tabaci and the nomenclature of the various genetic groups have been a subject of debate.Recent phylogenetic analyses indicate that B.tabaci is a complex composed of 28 morphologically indistinguishable species.In this article,we first review the debate and difficulties associated with B.tabaci's taxonomy and systematics,and argue for the need to apply the biological species concept in order to elucidate B.tabaci's systematics.We summarize the accumulated genetic and behavioural data on reproductive incompatibilities evident amongst phylogenetic mtCOI groups of B.tabaci.Crossing studies have been conducted with 14 of the 28 putative species covering 54 reciprocal inter-species pairs,and observations on mating behaviour have been conducted for seven species pairs.Data from both crossing trials and behavioural observations indicate a consistent pattern of reproductive isolation among the putative species.We then discuss the technical and conceptual complexities associated with crossing experiments and behavioural observations designed to reveal reproductive incompatibility.Finally,we elaborate on a strategy for further clarifying the pattern of reproductive isolation between B.tabaci groups and propose future research directions on the systematics of this complex.LIU Shu-sheng John Colvin Paul J De Barro 2012Journal of Integrative Agriculture2012,11,2:76
13Transcatheter embolization therapy in liver cancer:an update of clinical evidences显示文摘Transarterial chemoembolization(TACE) is a form of intra-arterial catheter-based chemotherapy that selectively delivers high doses of cytotoxic drug to the tumor bed combining with the effect of ischemic necrosis induced by arterial embolization.Chemoembolization and radioembolization are at the core of the treatment of liver hepatocellular carcinoma(HCC) patients who cannot receive potentially curative therapies such as transplantation,resection or percutaneous ablation.TACE for liver cancer has been proven to be useful in local tumor control,to prevent tumor progression,prolong patients' life and control patient symptoms.Recent evidence showed in patients with single-nodule HCC of 3 cm or smaller without vascular invasion,the5-year overall survival(OS) with TACE was similar to that with hepatic resection and radiofrequency ablation.Although being used for decades,Lipiodol~(Lipiodol~ Ultra Fluid~,Guerbet,France) remains important as a tumor-seeking and radio-opaque drug delivery vector in interventional oncology.There have been efforts to improve the delivery of chemotherapeutic agents to tumors.Drug-eluting bead(DEB) is a relatively novel drug delivery embolization system which allows for fixed dosing and the ability to release the anticancer agents in a sustained manner.Three DEBs are available,i.e.,Tandem~(CeloNova Biosciences Inc.,USA),DC-Beads~(BTG,UK) and HepaSphere~(BioSphere Medical,Inc.,USA).Transarterial radioembolization(TARE) technique has been developed,and proven to be efficient and safe in advanced liver cancers and those with vascular complications.Two types of radioembolization microspheres are available i.e.,SIR-Spheres~(Sirtex Medical Limited,Australia) and TheraSphere~(BTG,UK).This review describes the basic procedure of TACE,properties and efficacy of some chemoembolization systems and radioembolization agents which are commercially available and/or currendy under clinical evaluation.The key clinical trials of transcatheter arterial therapy for liver cancer are summarized.Yi-Xiang J.Wang Thierry De Baere Jean-Marc Idee Sebastien Ballet 2015Chinese Journal of Cancer Research2015,27,2:72
14Fermented liquid feed for pigs: an ancient technique for the future显示文摘Fermented liquid feed is feed that has been mixed with water at a ratio ranging from 1:1.5 to 1:4.By mixing with water,lactic acid bacteria and yeasts naturally occurring in the feed proliferate and produce lactic acid,acetic acid and ethanol which reduces the pH of the mixture.This reduction in pH inhibits pathogenic organisms from developing in the feed.In addition,when this low pH mixture is fed,it reduces the pH in the stomach of pigs and prevents the proliferation of pathogens such as coliforms and Salmonella in the gastrointestinal tract.For piglets,the use of fermented liquid feed offers the possibility of simultaneously providing feed and water,which may facilitate an easier transition from sow's milk to solid feed.Secondly,offering properly produced fermented liquid feed may strengthen the role of the stomach as the first line of defense against possible pathogenic infections by lowering the pH in the gastrointestinal tract thereby helping to exclude enteropathogens.Finally,feeding fermented liquid feed to pigs has been shown to improve the performance of suckling pigs,weaner pigs and growing-finishing pigs.In this review,current knowledge about the use of fermented liquid feed in pig diets will be discussed.This will include a discussion of the desirable properties of fermented liquid feed and factors affecting fermentation.In addition,advantages and disadvantages of fermented liquid feed will be discussed including its effects on gastrointestinal health,intestinal pH and the types of bacteria found in the gastrointestinal tract as well as the effects of fermented liquid feeds on pig performance.Joris AM Missotten Joris Michiels Jeroen Degroote Stefaan De Smet 2016Journal of Animal Science and Biotechnology2016,7,1:67

16Laparoscopic natural orifice specimen extraction-colectomy: A systematic review显示文摘Over the last 20 years, laparoscopic colorectal surgery has shown equal efficacy for benign and malignant colorectal diseases when compared to open surgery. However, a laparoscopic approach reduces postoperative morbidity and shortens hospital stay. In the quest to optimize outcomes after laparoscopic colorectal surgery, reduction of access trauma could be a way to improve recovery. To date, one method to reduce access trauma is natural orifice specimen extraction(NOSE). NOSE aims to reduce access trauma in laparoscopic colorectal surgery. The specimen is delivered via a natural orifice and the anastomosis is created intracorporeally. Different methods are used to extract the specimen and to create a bowel anastomosis. Currently, specimens are delivered transcolonically, transrectally, transanally, or transvaginally. Each of these NOSEprocedures raises specific issues with regard to operative technique and application. The presumed benefits of NOSE-procedures are less pain, lower analgesia requirements, faster recovery, shorter hospital stay, better cosmetic results, and lower incisional hernia rates. Avoidance of extraction site laparotomy is the most important characteristic of NOSE. Concerns associated with the NOSE-technique include bacterial contamination of the peritoneal cavity, inflammatory response, and postoperative outcomes, including postoperative pain and the functional and oncologic outcomes. These issues need to be studied in prospective randomized controlled trials. The aim of this systematic review is to describe the role of NOSE in minimally invasive colorectal surgery.Albert M Wolthuis Anthony de Buck van Overstraeten André D'Hoore 2014World Journal of Gastroenterology2014,20,36:65
17Pathophysiological 角色和在糖尿病的 nephropathy 的发炎的治疗学的含意显示文摘 Diabetes mellitus and its complications are becoming one of the most important health problems in the world. Diabetic nephropathy is now the main cause of end-stage renal disease. The mechanisms leading tothe development and progression of renal injury are not well known. Therefore, it is very important to f ind new pathogenic pathways to provide opportunities for early diagnosis and targets for novel treatments. At the present time, we know that activation of innate immunity with development of a chronic low grade inflammatory response is a recognized factor in the pathogenesis of diabetic nephropathy.

19欧洲呼吸学会和欧洲胸外科医师学会恶性胸膜间皮瘤诊疗指南显示文摘恶性胸膜间皮瘤(malignant pleural mesothelioma,MPM)是一种罕见肿瘤,但发病率正逐渐上升,且预后较差。2008年,欧洲呼吸学会(European Respiratory Society,ERS)和欧洲胸外科医师学会(European Society of Tho-racic Surgeons,ESTS)特别工作组召集各方专家计划制定MPM诊治经验及更新指南。为了使MPM得到及时准确的诊断,专家推荐对患者实施胸腔镜检查,有手术禁忌和胸腔粘连的病例除外。约10%的病例采用标准染色方法无法获得满意的结果。因此我们推荐在胸膜活检的基础上,采用特异性免疫组化标志物。由于目前缺乏一个统一的、切实有效的分期系统,我们推荐应用最新的TNM分期,并且提出三个阶段的治疗前评估。在MPM的治疗中,患者的体力状态评分和组织亚型是目前唯一的、具有重要临床价值的预后因素。在临床试验中,应对其它潜在因素进行初步探讨并予以报道。MPM对化疗高度耐受,仅有少数患者可接受根治性手术。本文对新的治疗方法和策略进行了综述。目前由于最佳综合治疗的资料有限,适合采用多种方案联合治疗策略的患者应被纳入专业机构的前瞻性试验中。A.

20Palaeozoic tectonic evolution of the Tianshan belt,NW China显示文摘The Chinese Tianshan belt is a major part of the southern Central Asian Orogenic Belt,extending westward to Kyrgyzstan and Kazakhstan.Its Paleozoic tectonic evolution,crucial for understanding the amalgamation of Central Asia,comprises two stages of subduction-collision.The first collisional stage built the Eo-Tianshan Mountains,before a Visean unconformity,in which all structures are verging north.It implied a southward subduction of the Central Tianshan Ocean beneath the Tarim active margin,that induced the Ordovician-Early Devonian Central Tianshan arc,to the south of which the South Tianshan back-arc basin opened.During the Late Devonian,the closure of this ocean led to a collision between Central Tianshan arc and the Kazakhstan-Yili-North Tianshan Block,and subsequently closure of the South Tianhan back-arc basin,producing two suture zones,namely the Central Tianshan and South Tianshan suture zones where ophiolitic mélanges and HP metamorphic rocks were emplaced northward.The second stage included the Late Devonian-Carboniferous southward subduction of North Tianshan Ocean beneath the Eo-Tianshan active margin,underlined by the Yili-North Tianshan arc,leading to the collision between the Kazakhstan-Yili-NTS plate and an inferred Junggar Block at Late Carboniferous-Early Permian time.The North Tianshan Suture Zone underlines likely the last oceanic closure of Central Asia Orogenic Belt;all the oceanic domains were consumed before the Middle Permian.The amalgamated units were affected by a Permian major wrenching,dextral in the Tianshan.The correlation with the Kazakh and Kyrgyz Tianshan is clarified.The Kyrgyz South Tianshan is equivalent to the whole part of Chinese Tianshan(CTS and STS) located to the south of Narat Fault and Main Tianshan Shear Zone;the so-called Middle Tianshan thins out toward the east.The South Tianshan Suture of Kyrgyzstan correlates with the Central Tianshan Suture of Chinese Tianshan.The evolution of this southern domain remains similar from east(Gangou area) to west until the Talas-Ferghana Fault,which reflects the convergence history between the Kazakhstan and Tarim blocks.Jacques CHARVET SHU LiangShu Sebastien LAURENT-CHARVET WANG Bo Michel FAURE Dominique CLUZEL CHEN Yan Koen De JONG 2011Science China Earth Sciences2011,54,2:57
