| 2 | Augmenting peripheral nerve regeneration using stem cells: A review of current opinion显示文摘Outcomes following peripheral nerve injury remain frustratingly poor. The reasons for this are multifactorial, although maintaining a growth permissive environment in the distal nerve stump following repair is arguably the most important. The optimal environment for axonal regeneration relies on the synthesis and release of many biochemical mediators that are temporally and spatially regulated with a high level of incompletely understood complexity. The Schwann cell(SC) has emerged as a key player in this process. Prolonged periods of distal nerve stump denervation, characteristic of large gaps and proximal injuries, have been associated with a reduction in SC number and ability to support regenerating axons. Cell based therapy offers a potential therapy for the improvement of outcomes following peripheral nerve reconstruction. Stem cells have the potential to increase the number of SCs and prolong their ability to support regeneration. They may also have the ability to rescue and replenish populations of chromatolytic and apoptotic neurons following axotomy. Finally, they can be used in non-physiologic ways to preserve injured tissues such as denervated muscle while neuronal ingrowth has not yet occurred. Aside from stem cell type, careful consideration must be given to differentiation status, how stem cells are supported following transplantation and how they will be delivered to the site of injury. It is the aim of this article to review current opinions on the strategies of stem cell based therapy for the augmentation of peripheral nerve regeneration. | Neil G Fairbairn Amanda M Meppelink Joanna Ng-Glazier Mark A Randolph Jonathan M Winograd | 2015 | World Journal of Stem Cells2015,7,1: | 12 |
| 3 | 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 |
| 4 | Colonic ulcerations may predict steroid-refractory course in patients with ipilimumab-mediated enterocolitis显示文摘AIM To investigate management of patients who develop ipilimumab-mediated enterocolitis, including association of endoscopic findings with steroid-refractory symptoms and utility of infliximab as second-line therapy.METHODS We retrospectively reviewed all patients at our centerwith metastatic melanoma who were treated with ipilimumab between March 2011 and May 2014. All patients received a standard regimen of intravenous ipilimumab 3 mg/kg every 3 wk for four doses or until therapy was stopped due to toxicity or disease progression. Basic demographic and clinical data were collected on all patients. For patients who developed grade 2 or worse diarrhea(increase of 4 bowel movements per day), additional data were collected regarding details of gastrointestinal symptoms, endoscopic findings and treatment course. Descriptive statistics were used.RESULTS A total of 114 patients were treated with ipilimumab during the study period and all were included. Sixteen patients(14%) developed ≥ grade 2 diarrhea. All patients were treated with high-dose corticosteroids(1-2 mg/kg prednisone daily or equivalent). Nine of 16 patients(56%) had ongoing diarrhea despite highdose steroids. Steroid-refractory patients received one dose of intravenous infliximab at 5 mg/kg, and all but one had brisk resolution of diarrhea. Fourteen of the patients underwent either colonoscopy or sigmoidoscopy with variable endoscopic findings, ranging from mild erythema to colonic ulcers. Among 8 patients with ulcers demonstrated by sigmoidoscopy or colonoscopy, 7 patients(88%) developed steroidrefractory symptoms requiring infliximab. With a median follow-up of 264 d, no major adverse events associated with prednisone or infliximab were reported.CONCLUSION In patients with ipilimumab-mediated enterocolitis, the presence of colonic ulcers on endoscopy was associated with a steroid-refractory course. | Animesh Jain Evan J Lipson William H Sharfman Steven R Brant Mark G Lazarev | 2017 | World Journal of Gastroenterology2017,23,11: | 8 |

| 6 | Pain sensation in pancreatic diseases is not uniform: The different facets of pancreatic pain显示文摘AIM: To systematically characterize specific pain patterns in the most frequent pancreatic diseases.METHODS: Pain in patients with chronic pancreatitis(n = 314), pancreatic cancer(n = 469), and other pancreatic tumors(n = 249) including mucinous(n = 20) and serous cystadenoma(n = 31), invasive(n = 37) and non-invasive intraductal papillary mucinous neoplasia(IPMN; n = 48), low stage(n = 18) and high stage neuroendocrine neoplasia(n = 44), and ampullary cancer(n = 51) was registered and correlated with clinicopathological data. Survival times were estimated by the Kaplan-Meier method. Patients alive at the follow-up time were censored. Survival curves were compared statistically using the log-rank test.RESULTS: Forty-nine point one percent of pancreatic cancer patients revealed no pain, whereas in chronic pancreatitis only 18.3% were pain free. In contrary, moderate/severe pain was registered in 15.1% in pancreatic cancer patients that was increased in chronic pancreatitis with up to 34.2%. Serous cystadenoma was asymptomatic in most cases(58.1%), whereas 78.9% of all mucinous cystadenoma patients suffered pain. In neuroendocrine neoplasia pain was not a key clinical symptom since 64% of low stage neuroendocrine neoplasia and 59% of high stage neuroendocrine neoplasia patients were pain free. Cancer localization in the pancreatic body and patients with malignant pancreatic neoplasms were associated with more severe pain. Tumor grading and stage did not show any impact on pain. Only in pancreatic cancer, pain was directly associated with impaired survival.CONCLUSION: Pancreatic pain depicts different patterns of abdominal pain sensation according to the respective pancreatic disorder and does not allow a unification of the term pancreatic pain. | Jan G D'Haese Mark Hartel Ihsan Ekin Demir Ulf Hinz Frank Bergmann Markus W Büchler Helmut Friess Güralp O Ceyhan | 2014 | World Journal of Gastroenterology2014,20,27: | 8 |

| 10 | 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 |
| 11 | Heme oxygenase-1 overexpression increases liver injury after bile duct ligation in rats显示文摘AIM: To investigate the effects of heme oxygenase-1 (HO-1) against oxidant-induced injury caused by bile duct ligation (BDL). METHODS: Either cobalt protoporphyrin (CoPP), a HO-1 inducer, or saline were injected intraperitoneally in male SD-rats. Three days later, BDL or sham-operations were performed. Rats were sacrificed 3 wk after BDL and livers were harvested for histology. Fibrosis was evaluated by sirius red staining and image analysis. Alpha-smooth muscular actin, which indicates activation of stellate cells, was detected by immunohistochemical staining, and cytokine and collagen-Ⅰα (Col-Ⅰα) mRNA expression was detected using RNase protection assays. RESULTS: Serum alanine transaminase increased 8-fold above normal levels one day after BDL. Surprisingly, enzyme release was not reduced in rats receiving CoPP. Liver fibrosis was evaluated 3 wk after BDL and the sirius red-positive area was found to be increased to about 7.8%. However, in CoPP pretreated rats sirius red- positive areas were increased to about 11.7% after BDL. Collagen-Ⅰα and TGF-β mRNA increased significantly by BDL. Again, this effect was increased by HO-1 overexpression.CONCLUSION: Hepatic fibrosis due to BDL is not reduced by the HO-1 inducer CoPP. In contrast, HO-1 overexpression increases liver injury in rats under conditions of experimental chronic cholestasis. | Matthias Froh Lars Conzelmann Peter Walbrun Susanne Netter Reiner Wiest Michael D Wheeler Mark Lehnert Takehiko Uesugi Jurgen Scholmerich Ronald G Thurman | 2007 | World Journal of Gastroenterology2007,13,25: | 4 |
| 12 | Risk Acceptability and Cost-Effectiveness of Protective Measures Against Terrorist Threats to Built Infrastructure Considering Multiple Threat Scenarios显示文摘Decisions are often needed about the need and/or extent of protective measures against explosive blast loads on built infrastructure. A decision support analysis considers fatality risks and cost-effectiveness of protective measures expressed in terms of expected cost spent on risk reduction per life saved for terrorist threats to infrastructure. The analysis is applicable to any item of infrastructure, but in this paper is applied to casualties arising from building facade glazing damage. Risks may be compared with risk acceptance criteria in the form of quantitative safety goals. The risk acceptability and cost-effectiveness of protective measures includes cost of the protective measures, attack probability,reduction in risk due to protective measures,probability of fatality conditional on successful terrorist attack and number of exposed individuals. | STEWART Mark G | 2008 | Transactions of Tianjin University2008,14,5: | 4 |
| 13 | Inflammatory bowel disease associated neoplasia:Asurgeon's perspective显示文摘Inflammatory bowel disease(IBD) is associated with increased risk of colorectal cancer(CRC). The risk is known to increase with longer duration of the disease, family history of CRC, and history of primary sclerosing cholangitis. The diagnosis of the neoplastic changes associated with IBD is difficult owing to the heterogeneous endoscopic appearance and interobserver variability of the pathological diagnosis. Screening and surveillance guidelines have been established which aim for early detection of neoplasia. Several surgical options are available for the treatment of IBD-associated neoplasia. Patients' morbidities, risk factors for CRC, degree and the extent of neoplasia must be considered in choosing the surgical treatment. A multidisciplinary team including the surgeon, gastroenterologist, pathologist, and the patient who has a clear understanding of the nature of their disease is needed to optimize outcomes. | Azah A Althumairi Mark G Lazarev Susan L Gearhart | 2016 | World Journal of Gastroenterology2016,22,3: | 4 |
| 14 | Function of longitudinal vs circular muscle fibers in esophageal peristalsis, deduced with mathematical modeling显示文摘We summarize from previous works the functions of circular vs. longitudinal muscle in esophageal peristaltic bolus transport using a mix of experimental data, the conservation laws of mechanics and mathematical modeling. Whereas circular muscle tone generates radial closure pressure to create a local peristaltic closure wave, longitudinal muscle tone has two functions, one physiological with mechanical implications, and one purely mechanical. Each of these functions independently reduces the tension of individual circular muscle fibers to maintain closure as a consequence of shortening of longitudinal muscle locally coordinated with increasing circular muscle tone. The physiological function is deduced by combining basic laws of mechanics with concurrent measurements of intraluminal pressure from manometry, and changes in cross sectional muscle area from endoluminal ultrasound from which local longitudinal shortening (LLS) can be accurately obtained. The purely mechanical function of LLS was discovered from mathematical modeling of peristaltic esophageal transport with the axial wall motion generated by LLS. Physiologically, LLS concentrates circular muscle fibers where closure pressure is highest. However, the mechanical function of LLS is to reduce the level of pressure required to maintain closure. The combined physiological and mechanical consequences of LLS are to reduce circular muscle fiber tension and power by as much as 1/10 what would be requiredfor peristalsis without the longitudinal muscle layer, a tremendous benefit that may explain the existence of longitudinal muscle fiber in the gut. We also review what is understood of the role of longitudinal muscle in esophageal emptying, reflux and pathology. | James G Brasseur Mark A Nicosia Anupam Pal Larry S Miller | 2007 | World Journal of Gastroenterology2007,13,9: | 4 |
| 15 | Unreliability of aortic size index to predict risk of aortic dissection in a patient with Turner syndrome显示文摘Aortic size index(ASI) has been proposed as a reliable criterion to predict risk for aortic dissection in Turner syndrome with significant thresholds of 20-25 mm/m2. We report a case of aortic arch dissection in a patient with Turner syndrome who, from the ASI thresholds proposed, was deemed to be at low risk of aortic dis-section or rupture and was not eligible for prophylactic surgery. This case report strongly supports careful monitoring and surgical evaluation even when the ASI is < 20 mm/m2 if other significant risk factors are present. | Jan Nijs Sandro Gelsomino Fabiana Lucà Orlando Parise Jos G Maessen Mark La Meir | 2014 | World Journal of Cardiology2014,6,5: | 3 |
