| 1 | Genetic factors that affect nonalcoholic fatty liver disease: A systematic clinical review显示文摘AIM: To investigate roles of genetic polymorphisms in non-alcoholic fatty liver disease(NAFLD) onset, severity, and outcome through systematic literature review. METHODS: The authors conducted both systematic and specific searches of Pub Med through December 2015 with special emphasis on more recent data(from 2012 onward) while still drawing from more historical data for background. We identified several specific genetic polymorphisms that have been most researched and, at this time, appear to have the greatest clinical significance on NAFLD and similar hepatic diseases. These were further investigated to assess their specific effects on disease onset and progression and the mechanisms by which these effects occur. RESULTS: We focus particularly on genetic polymorphisms of the following genes: PNPLA3, particularly the p. I148 M variant, TM6SF2, particularly the p. E167 K variant, and on variants in FTO, LIPA, IFNλ4, and iron metabolism, specifically focusing on HFE, and HMOX-1. We discuss the effect of these genetic variations and their resultant protein variants on the onset of fatty liver disease and its severity, including the effect on likelihood of progression to cirrhosis and hepatocellular carcinoma. While our principal focus is on NAFLD, we also discuss briefly effects of some of the variants on development and severity of other hepatic diseases, including hepatitis C and alcoholic liver disease. These results are briefly discussed in terms of clinical application and future potential for personalized medicine. CONCLUSION: Polymorphisms and genetic factors of several genes contribute to NAFLD and its end results. These genes hold keys to future improvements in diagnosis and management. | Tyler J Severson Siddesh Besur Herbert L Bonkovsky | 2016 | World Journal of Gastroenterology2016，22，29： | 12 |
| 2 | Magnetic anchor guidance for endoscopic submucosal dissection and other endoscopic procedures显示文摘Endoscopic submucosal dissection(ESD) is a wellestablished, minimally invasive treatment for superficial neoplasms of the gastrointestinal tract. The universal adoption of ESD has been limited by its slow learning curve, long procedure times, and high risk of complications. One technical challenge is the lack of a second hand that can provide traction, as in conventional surgery. Reliable tissue retraction that exposes the submucosal plane of dissection would allow for safer and more efficient dissection. Magnetic anchor guided endoscopic submucosal dissection(MAGESD) has potential benefits compared to other current traction methods. MAG-ESD offers dynamic tissue retraction independent of the endoscope mimicking a surgeon's 'second hand'. Two types of magnets can be used: electromagnets and permanent magnets. In this article we review the MAG-ESD technology, published work and studies of magnets in ESD. We also review the use of magnetic anchor guidance systems in natural orifice transluminal endoscopic surgery and the idea of magnetic non-contact retraction using surface ferromagentization. We discuss the current limitations, the future potential of MAG-ESD and the developments needed for adoption of this technology. | Mohamed Mortagy Neal Mehta Mansour A Parsi Seiichiro Abe Tyler Stevens John J Vargo Yutaka Saito Amit Bhatt | 2017 | World Journal of Gastroenterology2017，23，16： | 12 |
| 3 | Diagnostic and therapeutic direct peroral cholangioscopy using an intraductal anchoring balloon显示文摘AIM:To report our experience using a recently introduced anchoring balloon for diagnostic and therapeutic direct peroral cholangioscopy(DPOC).METHODS:Consecutive patients referred for diagnostic or therapeutic peroral cholangioscopy were evaluated in a prospective cohort study.The patients underwent DPOC using an intraductal anchoring balloon,which was recently introduced to allow consistent access to the biliary tree with an ultraslim upper endoscope.The device was later voluntarily withdrawn from the market by the manufacturer.RESULTS:Fourteen patients underwent DPOC using the anchoring balloon.Biliary access with an ultraslim upper endoscope was accomplished in all 14 patients.In 12(86%) patients,ductal access required sphincteroplasty with a 10-mm dilating balloon.Intraductal placement of the ultraslim upper endoscope allowed satisfactory visualization of the biliary mucosa to the level of the confluence of the right and left hepatic ducts in 13 of 14 patients(93%).Therapeutic interventions by DPOC were successfully completed in all five attempted cases(intraductal biopsy in one and DPOC guided laser lithotripsy in four).Adverse events occurred in a patient on immunosuppressive therapy who developed an intrahepatic biloma at the site of the anchoring balloon.This required hospitalization and antibiotics.Repeat endoscopic retrograde cholangiopancreatography 8 wk after the index procedure showed resolution of the biloma.CONCLUSION:Use of this anchoring balloon allowed consistent access to the biliary tree for performance of diagnostic and therapeutic DPOC distal to the biliary bifurcation. | Mansour A Parsi Tyler Stevens John J Vargo | 2012 | World Journal of Gastroenterology2012，18，30： | 8 |
| 4 | Tight junction disruption: Helicobacter pylori and dysregulation of the gastric mucosal barrier显示文摘Long-term chronic infection with Helicobacter pylori(H. pylori) is a risk factor for gastric cancer development. In the multi-step process that leads to gastric cancer,tight junction dysfunction is thought to occur and serve as a risk factor by permitting the permeation of luminal contents across an otherwise tight mucosa. Mechanisms that regulate tight junction function and structure in the normal stomach,or dysfunction in the infected stomach,however,are largely unknown. Although conventional tight junction components are expressed in gastric epithelial cells,claudins regulate paracellular permeability and are likely the target of inflammation or H. pylori itself. There are 27 different claudin molecules,each with unique properties that render the mucosa an intact barrier that is permselective in a way that is consistent with cell physiology. Understanding the architecture of tight junctions in the normal stomach and then changes that occur during infection is important but challenging,because most of the reports that catalog claudin expression in gastric cancer pathogenesis are contradictory. Furthermore,the role of H. pylori virulence factors,such as cytotoxin-associated gene A and vacoulating cytotoxin,in regulating tight junction dysfunction during infection is inconsistent in different gastric cell lines and in vivo,likely because non-gastric epithelial cell cultures were initially used to unravel the details of their effects on the stomach. Hampering further study,as well,is the relative lack of cultured cell models that have tight junction claudins that are consistent with native tissues. This summary will review the current state of knowledge about gastric tight junctions,normally and in H. pylori infection,and make predictions about the consequences of claudin reorganization during H. pylori infection. | Tyler J Caron Kathleen E Scott James G Fox Susan J Hagen | 2015 | World Journal of Gastroenterology2015，21，40： | 7 |

| 6 | Outcomes after arthroscopic repair of rotator cuff tears in the setting of mild to moderate glenohumeral osteoarthritis显示文摘BACKGROUND Rotator cuff pathology is a very common source of shoulder pain.Similarly,osteoarthritis of the glenohumeral joint can cause shoulder pain and produce similar symptoms.Surgical management can be indicated for both pathologies,however,outcomes data is limited when examining rotator cuff repair(RCR) in the setting of glenohumeral arthritis(GHOA).Thus,this study sought to determine outcomes for patients who undergo RCR in the setting of GHOA.AIM To evaluate if a relationship exists between outcomes of RCR in the setting of GHOA.METHODS This was a retrospective analysis of patients who underwent arthroscopic rotator cuff repair with concurrent glenohumeral osteoarthritis between 2010-2017.Patients were stratified based on rotator cuff tear size and glenohumeral osteoarthritis severity.Cohorts were paired 1:1 with patients without glenohumeral osteoarthritis.Patients included had a minimum two year follow-up.Rate of conversion to total shoulder arthroplasty,complication rates following initial surgery,and patient-reported outcome measures were collected.RESULTS A total of 142 patients were included.The number of patients that required total shoulder arthroplasty within two years after index surgery was low.2/71(2.8%) patients with GHOA,and 1/71(1.4%) without GHOA.Following rotator cuff repair,both groups showed favorable patientreported outcomes.CONCLUSION Patients with glenohumeral osteoarthritis who underwent arthroscopic rotator cuff repair showed comparable outcomes to patients without glenohumeral osteoarthritis. | Ian S Hong Allison J Rao Tyler L CarlLee Joshua D Meade Daniel J Hurwit Gregory Scarola David P Trofa Shadley C Schiffern Nady Hamid Patrick M Connor James E Fleischli Bryan Michael Saltzman | 2022 | World Journal of Orthopedics2022，13，7： | 2 |
| 7 | Local immunotherapy with interleuk in-2 delivered from biodegradable p olymer microspheres combined with interstitial chemotherapy:a novel treatme nt for experimental malignant glioma显示文摘OBJECTIVE:Local delivery of carmustine(BCNU)from biodegradable polymers prolon gs survival against experimental brain tumors.Moreover,paracrine administration of inte rleukin-2(IL-2)has been shown to elicit a potent antitumor immune response and to improve survival in animal brain tumor models.We r eport the use of a novel polymeric mic rosphere delivery vehicle to release IL-2.We demonstr ate both in vitro release of cytokine from the microspheres and histological evidence of the inflammatory response elicited by I L-2released from the microspheres i n the rat brain.These microspheres a re used to deliver IL-2,and biodegradable polymer wafers are used to deliver BCNU,directly at the site of an intracranially implanted glioma in the rat.The two agents administered locally show a s ynergistic effect.METHODS:Fischer 344rats challenged intracranially with 9L gliosarcoma received an intracranial implant of either empty microspheres or microspheres containing IL-2(IL-2MS ).Five days later,animals in each group were randomized to receiv e polymer implants loaded with 0,3.8,or 10%BCNU at the tumor site.RESULTS:Animals that received the combination of IL-2MS a nd 3.8%BCNU polymer(median survival,28.5d )or IL-2MS and 10%BCNU polymer(median survival,45.5d )showed significantly improved surv ival compared with animals that rece ived monotherapy with IL-2microsph eres(median survival,24d ),3.8%BCNU polymer(median survival,24d ),or 10%BCNU polymer(median survival,32.5d ).Control animals had a median survival of 18days.The combination of either 3.8or 10%BCNU polymer with IL-2MS resulted in 7and 25%long-term survivors,respectively.CONCLUSION:By showing synergy of IL-2and BCNU in an animal glioma model and using a reproducible synthetic delivery sy stem for each agent (i.e.,one that did not rely on genetic ally engineered cells or viruses),we hope that the combination of local immunotherapy and chemotherapy can take an important step closer to clinical applic ation in patients with malignant brain | Rhines LD DiMeco F Lawson HC Tyler BM Hanes J Olivi A Brem H | 2003 | 癌症2003，22，7： | 2 |

| 9 | 文化、不平等性与卫生服务提供显示文摘1动态不平等性对基层医疗卫生人力的影响
政治、社会、文化、专业群体皆建立在一致且常规的人类行为之上。当遭受巨大变革和内外压力时,这些群体会变得十分脆弱。尤其在动荡时期,这些群体往往更关注社会和文化的差异性,而非二者的一致性。尽管社会中的个体思维和行为会呈现较大的差异,但对健康的感知具有统一性,并在更广范围人群内尤为突出,这主要归因于文化价值观的作用。广义的文化心态会随着时间和地理位置的不同而不同,就像健康的社会决定因素也会因文化类型的不同而产生差异。 | Napier A D Ancarno C Butler B Calabrese J Chater A Chatterjee H Guesnet F Horne R Jacyna S Jadhav S Macdonald A Neuendorf U Parkhurst A Reynolds R Scambler G Shamdasani S Smith S Z Stougaard-Nielsen J Thomson L Tyler N Volkmann A M Walker T Watson J Williams A C Willott C Wilson J Woolf K | 2016 | 中国卫生政策研究2016，9，3： | 2 |
| 10 | Clinical outcomes of endoscopic management of pancreatic fluid collections in cirrhotics vs non-cirrhotics: A comparative study显示文摘BACKGROUND Endoscopic management of symptomatic pancreatic fluid collections (PFCs) using self-expandable metal stents (SEMS) placement has emerged as an innovative therapeutic approach with excellent efficacy, safety, and relatively few adverse outcomes. However, their use has not been studied in patients with cirrhosis. Cirrhotics tend to be considered less than optimal candidates due to concern for portal hypertension and coagulopathy related complications. AIM To compare the efficacy and safety of using SEMS for drainage of symptomatic PFCs in cirrhotic vs non-cirrhotic patients. METHODS We conducted a retrospective comparative analysis of patients with symptomatic PFCs [pancreatic pseudocyst (PP) or walled-off necrosis (WON)] who underwent endoscopic ultrasound (EUS)-guided placement of fully covered self-expandable metals stents or lumen-apposing self-expandable metal stents. All patients were followed clinically until resolution of PFCs or death. Definition:(1) Technical success was defined as successful placement of SEMS;and (2) Clinical success was defined as complete resolution of the PFCs without additional interventions including interventional radiology or surgery. Number of procedures performed per patient, number of patients who achieved complete resolution of the PFCs without additional interventions and procedure related adverse events were recorded.RESULTS From January 2012 to December 2017, a total of 88 patients underwent EUSguided drainage of symptomatic PFCs. Of these, 58 non cirrhotic patients underwent plastic stent insertion for management of PFC and 30 patients, 5 with cirrhosis and 25 without cirrhosis, underwent EUS-guided transmural drainage with SEMS, including 18 (60%) PP and 12 (40%) WON. Technical success was achieved in all 30 patients. Clinical success was achieved in 60% cirrhotic patients and 92% non-cirrhotics (P = 0.12). Procedure-related adverse events were 60% in cirrhotic and 28% non-cirrhotic (P = 0.62). Moreover, fatal adverse events were statistically more common in cirrhotics compared with non-cirrhotics (0 vs 40%;P = 0.023). Successful stent removal following resolution of the PFC, was 60% in cirrhotics and 80% in non-cirrhotics (P = 0.57). Post-procedure length of hospitalization was 18.6 ± 20.3 d in cirrhotics and 5.6 ± 13.7 d in non-cirrhotics (P = 0.084). CONCLUSION EUS-guided management of PFC using SEMS placement has a high technical and clinical success rate in non-cirrhotics. However, in cirrhotics caution must be exercised given the high morbidity and mortality as evidenced by our cohort, particularly for the endoscopic debridement of WONs. Larger, multicenter studies are warranted to further characterize the risk profile and outcomes in these patients. | Sobia Laique Matheus C Franco Tyler Stevens Amit Bhatt John J Vargo Prabhleen Chahal | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，6： | 2 |
