| 1 | Alcohol metabolites and lipopolysaccharide: Roles in the development and/or progression of alcoholic liver disease显示文摘The onset of alcoholic liver disease (ALD) is initiated by different cell types in the liver and a number of different factors including: products derived from ethanol-induced inflammation, ethanol metabolites, and the indirect reactions from those metabolites. Ethanol oxidation results in the production of metabolites that have been shown to bind and form protein adducts, and to increase inflammatory, fibrotic and cirrhotic responses. Lipopolysaccharide (LPS) has many deleterious effects and plays a significant role in a number of disease processes by increasing inflammatory cytokine release. In ALD, LPS is thought to be derived from a breakdown in the intestinal wall enabling LPS from resident gut bacterial cell walls to leak into the blood stream. The ability of adducts and LPS to independently stimulate the various cells of the liver provides for a two-hit mechanism by which various biological responses are induced and result in liver injury. Therefore, the purpose of this article is to evaluate the effects of a two-hit combination of ethanol metabolites and LPS on the cells of the liver to increase inflamma-tion and fi brosis, and play a role in the development and/or progression of ALD. | Courtney S Schaffert Michael J Duryee Carlos D Hunter Bartlett C Hamilton 3rd Amy L DeVeney Mary M Huerter Lynell W Klassen Geoffrey M Thiele | 2009 | World Journal of Gastroenterology2009，15，10： | 20 |
| 2 | Outcomes of patients with cirrhosis undergoing non-hepatic surgery:Risk assessment and management显示文摘The reported mortality rates in patients with cirrhosis undergoing various non-transplant surgical procedures range from 8.3% to 25%. This wide range of mortality rates is related to severity of liver disease, type of surgery, demographics of patient population, expertise of the surgical, anesthesia and intensive care unit team and finally, reporting bias. In this article, we will review the pathophysiology, morbidity and mortality associated with non-hepatic surgery in patients with cirrhosis, and then recommend an algorithm for risk assessment and evidence based management strategy to optimize post-surgical outcomes. | Farida Millwala Geoffrey C Nguyen Paul J Thuluvath | 2007 | World Journal of Gastroenterology2007，13，30： | 10 |
| 3 | Osteopontin is an important mediator of alcoholic liver disease via hepatic stellate cell activation显示文摘AIM: To investigate over-expression of Osteopontin(OPN) pathway expression and mechanisms of action in human alcoholic liver disease(ALD), in vivo and in vitro acute alcohol models. METHODS: OPN pathway was evaluated in livers from patients with progressive stages of human ALD and serum from drinkers with and without liver cirrhosis. In vitro stellate LX2 cells exposed to acute alcohol and in vivo in acute alcoholic steatosis mouse models were also investigated for OPN pathway expression and function. WT and OPN-/- mice were administered an acute dose of alcohol and extent of liver injury was examined by histopathology and liver biochemistry after 16-24 h. The causative role of OPN was studied in OPN knockout animals and in vitro in stellate LX2 cells, utilizing siRNA, aptamer and neutralizing antibodies to block OPN and OPN pathway. OPN pathway expression and downstream functional consequences were measured for signaling by Western blotting, plasmin activation by spectrophotometric assays and cell migration by confocal imaging and quantitation. RESULTS: OPN expression positively correlated with disease severity in patients with progressive stages of ALD. In vivo, associated with alcoholic steatosis, a single dose of acute alcohol significantly increased hepatic OPN mRNA and protein, and a cleaved OPN form in a dose dependent manner. OPN mRNA and secreted OPN also increased in parallel with activation of LX2 stellate cells within 4 h of a single dose of alcohol. Expression of OPN receptors, αvβ3-integrin and CD44, increased in human ALD, and in vivo and in vitro with alcohol administration. This was accompanied by downstream phosphorylation of Akt and Erk, increased mRNA expression of several fibrogenesis, fibrinolysis and extracellular matrix pathway genes, plasmin activation and hepatic stellate cell(HSC) migration. Inhibition of OPN and OPN-receptor mediated signaling partially inhibited alcohol-induced HSC activation, plasmin activity and cell migration. CONCLUSION: OPN is a key mediator of the alcoholinduced effects on hepatic stellate cell functions and liver fibrogenesis. | Devanshi Seth Alastair Duly Paul C Kuo Geoffrey W McCaughan Paul S Haber | 2014 | World Journal of Gastroenterology2014，20，36： | 5 |
| 4 | Irritable bowel syndrome: A concise review of current treatment concepts显示文摘Irritable bowel syndrome(IBS) is one of the most common gastrointestinal disorders causing patients to seek medical treatment. It is relatively resource intensive and the source of significant morbidity. Recent insights into the pathophysiology and treatment of IBS has given clinicians more options than ever to contend with this disorder. The purpose of our paper is to review older, 'classic' treatments for IBS as well as newer agents and 'alternative' therapies. We discuss the evidence base of these drugs and provide context to help develop appropriate treatment plans for IBS patients. | Geoffrey C Wall Ginelle A Bryant Michelle M Bottenberg Erik D Maki rew R Miesner | 2014 | World Journal of Gastroenterology2014，20，27： | 5 |

| 6 | Quality improvement in pediatric inflammatory bowel disease: Moving forward to improve outcomes显示文摘In recent years,pediatric health care has embraced the concept of quality improvement to improve patient outcomes.As quality improvement efforts are implemented,network collaboration(where multiple centers and practices implement standardized programs)is a popular option.In a collaborative network,improvement in the conduct of structural,process and outcome quality measures can lead to improvements in overall health,and benchmarks can be used to assess and compare progress.In this review article,we provided an overview of the quality improvement movement and the role of quality indicators in this movement.We reviewed current quality improvement efforts in pediatric inflammatory bowel disease (IBD),as well as other pediatric chronic illnesses.We discussed the need to standardize the development of quality indicators used in quality improvement networks to assess medical care,and the validation techniques which can be used to ensure that process indicators result in improved outcomes of clinical significance.We aimed to assess current quality improvement efforts in pediatric IBD and other diseases,such as childhood asthma,childhood arthritis,and neonatal health.By doing so,we hope to learn from their successes and failures and to move the field forward for future improvements in the care provided to children with IBD. | Pauline Quach Geoffrey C Nguyen Eric I Benchimol | 2013 | World Journal of Gastroenterology2013，19，38： | 4 |
| 7 | Interventions and targets aimed at improving quality in inflammatory bowel disease ambulatory care显示文摘Over the past decade,there has been increasing focus on improving the quality of healthcare delivered to patients with chronic diseases,including inflammatory bowel disease.Inflammatory bowel disease is a complex,chronic condition with associated morbidity,health care costs,and reductions in quality of life.The condition is managed primarily in the outpatient setting.The delivery of high quality of care is suboptimal in several ambulatory inflammatory bowel disease domains including objective assessments of disease activity,the use of steroid-sparing agents,screening prior to anti-tumor necrosis factor therapy,and monitoring thiopurine therapy.This review outlines these gaps in performance and provides potential initiatives aimed at improvement including reimbursement programs,quality improvement frameworks,collaborative efforts in quality improvement,and the use of healthcare information technology. | Adam V Weizman Geoffrey C Nguyen | 2013 | World Journal of Gastroenterology2013，19，38： | 4 |

| 11 | Presence of phthalates in gastrointestinal medications: Is there a hidden danger?显示文摘Pharmaceutical companies that produce gastrointestinal(GI)medications often utilize phthalates for their ability to localize medication release.Commonly prescribed GI medications that may utilize phthalates are 5-Aminosalicylates,proton pump inhibitors,and pancreatic enzymes.Our understanding of the cumulative health effects of phthalates from medications remains unclear,and there is increasing evidence that phthalates are not harmless.Experimental studies in animals have shown that phthalates,specifically dibutyl phthalate and Di-(2-ethyl-hexyl)phthalate,have the potential to alter and/or inhibit reproductive biology and in utero development.Despite the lack of definitive human data,many cohort and cross-sectional studies demonstrate concerning associations between phthalates and poor health status,specifically developmental problems.Longitudinal studies and studies with larger sample sizes are required to determine whether phthalates actually cause negative health consequences.It is also important that physicians regularly review and discuss with patients the medicinal ingredients in their medications and supplements,specifically in pregnant woman with inflammatory bowel disease. | Zane R Gallinger Geoffrey C Nguyen | 2013 | World Journal of Gastroenterology2013，19，41： | 2 |
