| 1 | Schistosoma mansoni proteins attenuate gastrointestinal motility disturbances during experimental colitis in mice显示文摘AIM:To investigate the therapeutic effect of Schistosoma mansoni(S.mansoni) soluble worm proteins on gastrointestinal motility disturbances during experimental colitis in mice. METHODS:Colitis was induced by intrarectal injection of trinitrobenzene sulphate(TNBS) and 6 h later,mice were treated ip with S.mansoni proteins.Experiments were performed 5 d after TNBS injection.Inflammationwas quantified using validated inflammation parameters. Gastric emptying and geometric center were measured to assess in vivo gastrointestinal motility.Peristaltic activity of distal colonic segments was studied in vitro using a modified Trendelenburg set-up.Cytokine profiles of T-lymphocytes isolated from the colon were determined by real time reverse transcriptase-polymerase chain reaction. RESULTS:Intracolonic injection of TNBS caused severe colitis.Treatment with S.mansoni proteins significantly ameliorated colonic inflammation after 5 d.TNBS did not affect gastric emptying but significantly decreased the geometric center and impaired colonic peristaltic activity 5 d after the induction of colitis.Treatment with S.mansoni proteins ameliorated these in vivo and in vitro motility disturbances.In addition,TNBS injection caused a downregulation of effector T cell cytokines after 5 d,whereas a S.mansoni protein effect was no longer observed at this time point. CONCLUSION:Treatment with S.mansoni proteins attenuated intestinal inflammation and ameliorated motility disturbances during murine experimental colitis. | Nathalie E Ruyssers Benedicte Y De Winter Joris G De Man Natacha D Ruyssers Ann J Van Gils Alex Loukas Mark S Pearson Joel V Weinstock Paul A Pelckmans Tom G Moreels | 2010 | World Journal of Gastroenterology2010，16，6： | 11 |
| 2 | Significant association between ABO blood group and pancreatic cancer显示文摘AIM:To evaluate whether the ABO blood group is related to pancreatic cancer risk in the general population of the United States.METHODS:Using the University of Pittsburgh's clinicalpancreatic cancer registry,the blood donor database from our local blood bank (Central Blood Bank),and the blood product recipient database from the regional transfusion service (Centralized Transfusion Service) in Pittsburgh,Pennsylvania,we identified 274 pancreatic cancer patients with previously determined serological ABO blood group information.The ABO blood group frequency was compared between these patients and 708842 individual,community-based blood donors who had made donations to Pittsburgh's Central Blood Bank between 1979 and 2009.RESULTS:The frequency of blood group A was statistically significantly higher amongst pancreatic cancer patients compared to its frequency amongst the regional blood donors [47.63% vs 39.10%,odds ratio (OR)=1.43,P=0.004].Conversely,the frequency of blood group O was significantly lower amongst pancreatic cancer patients relative to the community blood donors (32.12% vs 43.99%,OR=0.60,P=0.00007).There were limited blood group B (n=38) and AB (n=17) pancreatic cancer patients;the overall P trend value comparing patient to donor blood groups was 0.001.CONCLUSION:The ABO blood group is associated with pancreatic cancer risk.Future studies should examine the mechanism linking pancreatic cancer risk to ABO blood group. | Julia B Greer Mark H Yazer Jay S Raval M Michael Barmada Randall E Brand David C Whitcomb | 2010 | World Journal of Gastroenterology2010，16，44： | 10 |

| 4 | Upper gastrointestinal tract capsule endoscopy using a nurse-led protocol: First reported experience显示文摘AIM To test the feasibility and performance of a novel upper gastrointestinal(GI) capsule endoscope using a nurse-led protocol. METHODS We conducted a prospective cohort analysis of patients who declined gastroscopy(oesophagogastroduodenoscopy, OGD) but who consented to upper GI capsule endoscopy. Patients swallowed the upper GI capsule following ingestion of 1 liter of water(containing simethicone). A series of positional changes were used to exploit the effects of water flow and move the upper GI capsule from one gravity-dependent area to another using a nurse-led protocol. Capsule transit time, video reading time, mucosal visualisation, pathology detection and patient tolerance was evaluated.RESULTS Fifty patients were included in the study. The mean capsule transit times in the oesophagus and stomach were 28 s and 68 min respectively. Visualisation of the following major anatomical landmarks was achieved(graded 1-5: Poor to excellent): Oesophagus, 4.8(± 0.5); gastro-oesophageal junction(GOJ), 4.8(± 0.8); cardia, 4.8(± 0.8); fundus, 3.8(± 1.2); body, 4.5(± 1); antrum, 4.5(± 1); pylorus, 4.7(± 0.8); duodenal bulb, 4.7(± 0.7); second part of the duodenum(D2), 4.7(± 1). The upper GI capsule reached D2 in 64% of patients. The mean video reading time was 48 min with standard playback mode and 20 min using Quickview(P = 0.0001). No pathology was missed using Quickview. Procedural tolerance was excellent. No complications were seen with the upper GI capsule. CONCLUSION The upper GI capsule achieved excellent views of the upper GI tract. Future studies should compare the diagnostic accuracy between upper GI capsule and OGD. | Hey-Long Ching Ailish Healy Victoria Thurston Melissa F Hale Reena Sidhu Mark E McAlindon | 2018 | World Journal of Gastroenterology2018，24，26： | 9 |
| 5 | Capsule endoscopy:Current practice and future directions显示文摘Capsule endoscopy(CE)has transformed investigation of the small bowel providing a non-invasive,well tolerated means of accurately visualising the distal duodenum,jejunum and ileum.Since the introduction of small bowel CE thirteen years ago a high volume of literature on indications,diagnostic yields and safety profile has been presented.Inclusion in national and international guidelines has placed small bowel capsule endoscopy at the forefront of investigation into suspected diseases of the small bowel.Most commonly,small bowel CE is used in patients with suspected bleeding or to identify evidence of active Crohn’s disease(CD)(in patients with or without a prior history of CD).Typically,CE is undertaken after upper and lower gastrointestinal flexible endoscopy has failed to identify a diagnosis.Small bowel radiology or a patency capsule test should be considered prior to CE in those at high risk of strictures(such as patients known to have CD or presenting with obstructive symptoms)to reduce the risk of capsule retention.CE also has a role in patients with coeliac disease,suspected small bowel tumours and other small bowel disorders.Since the advent of small bowel CE,dedicated oesophageal and colon capsule endoscopes have expanded the fields of application to include the investigation of upper and lower gastrointestinal disorders.Oesophageal CE may be used to diagnose oesophagitis,Barrett’s oesophagus and varices but reliability in identifying gastroduodenal pathology is unknown and it does not have biopsy capability.Colon CE provides an alternative to conventional colonoscopy for symptomatic patients,while a possible role in colorectal cancer screening is a fascinating prospect.Current research is already addressing the possibility of controlling capsule movement and developing capsules which allow tissue sampling and the administration of therapy. | Melissa F Hale Reena Sidhu Mark E McAlindon | 2014 | World Journal of Gastroenterology2014，20，24： | 9 |
| 6 | Alternatives for large-scale production of cultured beef: A review显示文摘Cultured beef is a method where stem cells from skeletal muscle of cows are cultured in vitro to gain edible muscle tissue. For large-scale production of cultured beef, the culture technique needs to become more efficient than today's 2-dimensional(2D) standard technique that was used to make the first cultured hamburger. Options for efficient large-scale production of stem cells are to culture cells on microcarriers, either in suspension or in a packed bed bioreactor, or to culture aggregated cells in suspension. We discuss the pros and cons of these systems as well as the possibilities to use the systems for tissue culture. Either of the production systems needs to be optimized to achieve an efficient production of cultured beef. It is anticipated that the optimization of large-scale cell culture as performed for other stem cells can be translated into successful protocols for bovine satellite cells resulting in resource and cost efficient cultured beef. | Matilda S M Moritz Sanne E L Verbruggen Mark J Post | 2015 | Journal of Integrative Agriculture2015，14，2： | 7 |

| 8 | Efficacy of peroral endoscopic myotomy vs other achalasia treatments in improving esophageal function显示文摘AIM: To assess and compare the esophageal function after peroral endoscopic myotomy(POEM) vs other conventional treatments in achalasia.METHODS: Chart review of all achalasia patients who underwent POEM, laparoscopic Heller myotomy(LHM) or pneumatic dilation(PD) at our institution between January 2012 and March 2015 was performed. Patient demographics, type of achalasia, prior treatments, pre- and post-treatment timed barium swallow(TBE) and high-resolution esophageal manometry(HREM) findings were compared between the three treatment groups. Patients who had both pre- and 2 mo posttreatment TBE or HREM were included in the final analysis. TBE parameters compared were barium column height, width and volume of barium remaining at 1 and 5 min. HREM parameters compared were basal lower esophageal sphincter(LES) pressures and LES-integrated relaxation pressures(IRP). Data are presented as mean ± SD, median [25th, 75 th percentiles] or frequency(percent). Analysis of variance, KruskalWallis test, Pearsons χ~2 test and Fishers Exact tests were used for analysis.RESULTS: A total of 200 achalasia patients were included of which 36 underwent POEM, 22 underwent PD and 142 underwent LHM. POEM patients were older(55.4 ± 16.8 years vs 46.5 ± 15.7 years, P = 0.013) and had higher BMI than LHM(29.1 ± 5.9 kg/m^2 vs 26 ± 5.1 kg/m^2, P = 0.012). More number of patients in POEM and PD groups had undergone prior treatments compared to LHM group(72.2% vs 68.2% vs 44.3% respectively, P = 0.003). At 2 mo post-treatment, all TBE parameters including barium column height, width and volume remaining at 1 and 5 min improved significantly in all three treatment groups(P = 0.01 to P < 0.001) except the column height at 1 min in PD group(P = 0.11). At 2 mo post-treatment, there was significant improvement in basal LES pressure and LES-IRP in both LHM(40.5 mm Hg vs 14.5 mm Hg and 24 mm Hg vs 7.1 mm Hg respectively, P < 0.001) and POEM groups(38.7 mm Hg vs 11.4 mm Hg and 23.6 mm Hg vs 6.6 mm Hg respectively, P < 0.001). However, when the efficacy of three treatments were compared to each other in terms of improvement in TBE or HREM parameters at 2 mo, there was no significant difference(P > 0.05).CONCLUSION: POEM, PD and LHM were all effective in improving esophageal function in achalasia at shortterm. There was no difference in efficacy between the three treatments. | Madhusudhan R Sanaka Umar Hayat Prashanthi N Thota Ramprasad Jegadeesan Monica Ray Scott L Gabbard Neha Wadhwa Rocio Lopez Mark E Baker Sudish Murthy Siva Raja | 2016 | World Journal of Gastroenterology2016，22，20： | 7 |

| 10 | Role of functional imaging in the development and refinement of invasive neuromodulation for psychiatric disorders显示文摘Deep brain stimulation(DBS) is emerging as a pow-erful tool for the alleviation of targeted symptoms in treatment-resistant neuropsychiatric disorders. Despite the expanding use of neuropsychiatric DBS, the mecha-nisms responsible for its effects are only starting to be elucidated. Several modalities such as quantitative elec-troencephalography as well a intraoperative recordings have been utilized to attempt to understand the under-pinnings of this new treatment modality, but functional imaging appears to offer several unique advantages. Functional imaging techniques like positron emission tomography, single photon emission computed tomog-raphy and functional magnetic resonance imaging have been used to examine the effects of focal DBS on activ-ity in a distributed neural network. These investigations are critical for advancing the field of invasive neuro-modulation in a safe and effective manner, particularly in terms of defining the neuroanatomical targets and refining the stimulation protocols. The purpose of this review is to summarize the current functional neuroim-aging findings from neuropsychiatric DBS implantation for three disorders: treatment-resistant depression, obsessive-compulsive disorder, and Tourette syndrome. All of the major targets will be discussed(Nucleus ac-cumbens, anterior limb of internal capsule, subcallosal cingulate, Subthalamic nucleus, Centromedial nucleus of the thalamus-Parafasicular complex, frontal pole, and dorsolateral prefrontal cortex). We will also address some apparent inconsistencies within this literature, and suggest potential future directions for this promis-ing area. | Nolan R Williams Joseph J Taylor Kayla Lamb Colleen A Hanlon E Baron Short Mark S George | 2014 | World Journal of Radiology2014，6，10： | 6 |

| 12 | Endoscopic retrograde cholangiography for pediatric choledocholithiasis: Assessing the need for endoscopic intervention显示文摘AIM:To assess pediatric patients for choledocholithiasis.We applied current adult guidelines to identify predictivefactors in children.METHODS:A single-center retrospective analysis was performed at a tertiary children's hospital.We evaluated 44 consecutive pediatric patients who underwent endoscopic retrograde cholangiography(ERCP) for suspected choledocholithiasis.Patients were stratified into those with common bile duct stones(CBDS) at ERCP vs those that did not using the American Society of Gastrointestinal Endoscopy(ASGE) guidelines(Very Strong and Strong criteria) for suspected CBDS.RESULTS:CBDS were identified in 84% at the time of ERCP.Abdominal ultrasound identified CBDS in 36% of patients.Conjugated bilirubin ≥ 0.5 mg/d L was an independent risk factor for CBDS(P = 0.003).The Very Strong(59.5%) and Strong(48.6%) ASGE criteria identified the majority of patients(P = 0.0001).A modified score using conjugated bilirubin had a higher sensitivity(81.2% vs 59.5%) and more likely to identify a stone than the standard criteria,odds ratio of 25.7 compared to 8.8.Alanine aminotransferase and gamma-glutamyl transferase values identified significant differences in a subset of patients with odds ratio of 4.1 and 3.25,respectively.CONCLUSION:Current adult guidelines identified the majority of pediatric patients with CBDS,but specific pediatric guidelines may improve detection,thus decreasing risks and unnecessary procedures. | Douglas S Fishman Bruno P Chumpitazi Isaac Raijman Cynthia Man-Wai Tsai E O’Brian Smith Mark V Mazziotti Mark A Gilger | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，11： | 6 |
| 13 | Does aspirin or non-aspirin non-steroidal anti-inflammatory drug use prevent colorectal cancer in inflammatory bowel disease?显示文摘AIM: To determine whether aspirin or non-aspirin nonsteroidal anti-inflammatory drugs(NA-NSAIDs) prevent colorectal cancer(CRC) in patients with inflammatory bowel disease(IBD).METHODS: We performed a systematic review and meta-analysis. We searched for articles reporting the risk of CRC in patients with IBD related to aspirin or NANSAID use. Pooled odds ratios(OR) and 95%CIs were determined using a random-effects model. Publication bias was assessed using Funnel plots and Egger's test. Heterogeneity was assessed using Cochran's Q and the I2 statistic.RESULTS: Eight studies involving 14917 patients and 3 studies involving 1282 patients provided data on the risk of CRC in patients with IBD taking NA-NSAIDs and aspirin respectively. The pooled OR of developing CRC after exposure to NA-NSAIDs in patients with IBD was 0.80(95%CI: 0.39-1.21) and after exposure to aspirin it was 0.66(95%CI: 0.06-1.39). There was significant heterogeneity(I2 > 50%) between the studies. There was no change in the effect estimates on subgroup a na ly s e s o f t he po pulat io n s t udie d o r w he t he r adjustment or matching was performed.CONCLUSION: There is a lack of high quality evidence on this important clinical topic. From the available evidence NA-NSAID or aspirin use does not appear to be chemopreventative for CRC in patients with IBD. | Nick E Burr Mark A Hull Venkataraman Subramanian | 2016 | World Journal of Gastroenterology2016，22，13： | 6 |
| 14 | Less common etiologies of exocrine pancreatic insufficiency显示文摘Exocrine pancreatic insufficiency(EPI), an important cause of maldigestion and malabsorption, results from primary pancreatic diseases or secondarily impaired exocrine pancreatic function. Besides cystic fibrosis and chronic pancreatitis, the most common etiologies of EPI, other causes of EPI include unresectable pancreatic cancer, metabolic diseases(diabetes); impaired hormonal stimulation of exocrine pancreatic secretion by cholecystokinin(CCK); celiac or inflammatory bowel disease(IBD) due to loss of intestinal brush border proteins; and gastrointestinal surgery(asynchrony between motor and secretory functions, impaired enteropancreatic feedback, and inadequate mixing of pancreatic secretions with food). This paper reviews such conditions that have less straightforward associations with EPI and examines the role of pancreatic enzyme replacement therapy(PERT). Relevant literature was identified by database searches. Most patients with inoperable pancreatic cancer develop EPI(66%-92%). EPI occurs in patients with type 1(26%-57%) or type 2 diabetes(20%-36%) and is typically mild to moderate; by definition, all patients with type 3 c(pancreatogenic) diabetes have EPI. EPI occurs in untreated celiac disease(4%-80%), but typically resolves on a gluten-free diet. EPI manifests in patients with IBD(14%-74%) and up to 100% of gastrointestinal surgery patients(47%-100%; dependent on surgical site). With the paucity of published studies on PERT use for these conditions, recommendations for or against PERT use remain ambiguous. The authors conclude that there is an urgent need to conduct robust clinical studies to understand the validity and nature of associations between EPI and medical conditions beyond those with proven mechanisms, and examine the potential role for PERT. | Vikesh K Singh Mark E Haupt David E Geller Jerry A Hall Pedro M Quintana Diez | 2017 | World Journal of Gastroenterology2017，23，39： | 5 |
| 15 | 子叶供氮对不同基因型大豆种子组分的影响显示文摘【目的】本研究通过种子快速生长期对3个不同基因型大豆(Evans-低蛋白品种;PI132.217-高蛋白稳定品种;Proto-高蛋白品种)供氮以了解供氮是否能提高种子蛋白质含量并改变种子组分,为大豆合理施氮和育种提供参考。【方法】采用液体组培法,即在植株开花后第18天,采集体积相同的种子,将子叶培养在含氮量不同的营养液中(0、37、75和150mmol·L-1谷氨酰胺)。在植株开花后的第24,30,36和42天以及在液体组培的第6,12,18和24天,分别收集种子和子叶测定干重(DW)和种子组分。【结果】供氮条件下种子鲜重(FW)和干重的积累速率明显比在植株上快。与植株上种子相比,Evans和Proto在供给37mmol·L-1谷氨酰胺时种子生长迅速,蛋白质-N积累量较高;供氮量超过75mmol·L-1种子中积累较多的非蛋白-N,脂肪积累量下降。PI132.217在供氮条件下种子生长速率和蛋白质含量均未增加,供氮量超过37mmol·L-1种子脂肪和淀粉含量下降。3个基因型大豆植株供氮能力存在差异,PI132.217植株供氮能力较高(约40mmol·L-1谷氨酰胺),而Evans和Proto植株供氮力较低(约20mmol·L-1谷氨酰胺),所以种子生长和蛋白质积累对供氮反应敏感。【结论】由于大豆植株供氮量不足,所以供氮可明显使低蛋白质品种种子蛋白质含量提高,但过量供氮可能因种子细胞中C源不足和N利用率低而限制种子生长和蛋白质积累。不同基因型品种在供氮量和氮利用率上存在遗传差异,通过遗传育种进行基因改良,提高种子的供氮能力和氮代谢能力可能是提高大豆种子蛋白质含量的重要途径。 | 周瑞莲 赵哈林 杨树德 Westgate E Mark | 2008 | 中国农业科学2008，41，10： | 5 |
| 16 | Estrogen receptor expression in chronic hepatitis C and hepatocellular carcinoma pathogenesis显示文摘AIM To investigate gender-specific liver estrogen receptor(ER) expression in normal subjects and patients with hepatitis C virus(HCV)-related cirrhosis and hepatocellular carcinoma(HCC).METHODS Liver tissues from normal donors and patients diagnosed with HCV-related cirrhosis and HCV-related HCC were obtained from the NIH Liver Tissue and Cell Distribution System. The expression of ER subtypes, ERα and ERβ, were evaluated by Western blotting and real-time RT-PCR. The subcellular distribution of ERα and ERβ was further determined in nuclear and cytoplasmic tissue lysates along with the expression ofinflammatory [activated NF-κB and IκB-kinase(IKK)] and oncogenic(cyclin D1) markers by Western blotting and immunohistochemistry. The expression of ERα and ERβ was correlated with the expression of activated NF-κB, activated IKK and cyclin D1 by Spearman's correlation. RESULTS Both ER subtypes were expressed in normal livers but male livers showed significantly higher expression of ERα than females(P < 0.05). We observed significantly higher m RNA expression of ERα in HCV-related HCC liver tissues as compared to normals(P < 0.05) and ERβ in livers of HCV-related cirrhosis and HCV-related HCC subjects(P < 0.05). At the protein level, there was a significantly higher expression of nuclear ERα in livers of HCV-related HCC patients and nuclear ERβ in HCV-related cirrhosis patients as compared to normals(P < 0.05). Furthermore, we observed a significantly higher expression of phosphorylated NF-κB and cyclin D1 in diseased livers(P < 0.05). There was a positive correlation between the expression of nuclear ER subtypes and nuclear cyclin D1 and a negative correlation between cytoplasmic ER subtypes and cytoplasmic phosphorylated IKK in HCV-related HCC livers. These findings suggest that dysregulated expression of ER subtypes following chronic HCVinfection may contribute to the progression of HCVrelated cirrhosis to HCV-related HCC.CONCLUSION Gender differences were observed in ERα expression in normal livers. Alterations in ER subtype expression observed in diseased livers may influence genderrelated disparity in HCV-related pathogenesis. | Janaki K Iyer Mamta Kalra Anil Kaul Mark E Payton Rashmi Kaul | 2017 | World Journal of Gastroenterology2017，23，37： | 5 |
| 17 | Tenascin C upregulates interleukin-6 expression in human cardiac myofibroblasts via toll-like receptor 4显示文摘AIM:To investigate the effect of Tenascin C(TNC)on the expression of pro-inflammatory cytokines and matrixmetalloproteinases in human cardiac myofibroblasts(CMF).METHODS:CMF were isolated and cultured from patients undergoing coronary artery bypass grafting.Cultured cells were treated with either TNC(0.1μmol/L,24 h)or a recombinant protein corresponding to different domains of the TNC protein;fibrinogen-like globe(FBG)and fibronectin typeⅢ-like repeats(TNⅢ5-7)(both 1μmol/L,24 h).The expression of the proinflammatory cytokines;interleukin(IL)-6,IL-1β,TNFαand the matrix metalloproteinases;MMPs(MMP1,2,3,9,10,MT1-MMP)was assessed using real time RT-PCR and western blot analysis.RESULTS:TNC increased both IL-6 and MMP3(P<0.01)mR NA levels in cultured human CMF but had no significant effect on the other markers studied.The increase in IL-6 mR NA expression was mirrored by an increase in protein secretion as assessed by enzymelinked immunosorbant assay(P<0.01).Treating CMF with the recombinant protein FBG increased IL-6mR NA and protein(P<0.01)whereas the recombinant protein TNⅢ5-7 had no effect.Neither FBG nor TNⅢ5-7 had any significant effect on MMP3 expression.The expression of toll-like receptor 4(TLR4)in human CMF was confirmed by real time RT-PCR,western blot and immunohistochemistry.Pre-incubation of cells with TLR4neutralising antisera attenuated the effect of both TNC and FBG on IL-6 mR NA and protein expression.CONCLUSION:TNC up-regulates IL-6 expression in human CMF,an effect mediated through the FBG domain of TNC and via the TLR4 receptor. | Azhar Maqbool Emma J Spary Iain W Manfield Michaela Ruhmann Lorena Zuliani-Alvarez Filomena O Gamboa-Esteves Karen E Porter Mark J Drinkhill Kim S Midwood Neil A Turner | 2016 | World Journal of Cardiology2016，8，5： | 4 |
| 18 | Miniature gastrointestinal endoscopy: Now and the future显示文摘Since its original application,gastrointestinal(GI)endoscopy has undergone many innovative transformations aimed at expanding the scope,safety,accuracy,acceptability and cost-effectiveness of this area of clinical practice.One method of achieving this has been to reduce the caliber of endoscopic devices.We propose the collective term“Miniature GI Endoscopy”.In this Opinion Review,the innovations in this field are explored and discussed.The progress and clinical use of the three main areas of miniature GI endoscopy(ultrathin endoscopy,wireless endoscopy and scanning fiber endoscopy)are described.The opportunities presented by these technologies are set out in a clinical context,as are their current limitations.Many of the positive aspects of miniature endoscopy are clear,in that smaller devices provide access to potentially all of the alimentary canal,while conferring high patient acceptability.This must be balanced with the costs of new technologies and recognition of device specific challenges.Perspectives on future application are also considered and the efforts being made to bring new innovations to a clinical platform are outlined.Current devices demonstrate that miniature GI endoscopy has a valuable place in investigation of symptoms,therapeutic intervention and screening.Newer technologies give promise that the potential for enhancing the investigation and management of GI complaints is significant. | John J McGoran Mark E McAlindon Prasad G Iyer Eric J Seibel Rehan Haidry Laurence B Lovat Sarmed S Sami | 2019 | World Journal of Gastroenterology2019，25，30： | 4 |
