| 2 | 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 |

| 4 | Radioembolization for the treatment of unresectable hepatocellular carcinoma:A clinical review显示文摘Hepatocellular carcinoma(HCC)is the sixth most common cancer in the world.The majority of patients with HCC present with unresectable disease.These patients have historically had limited treatment options secondary to HCC demonstrating chemoresistance to the currently available systemic therapies.Additionally, normal liver parenchyma has shown intolerance to tumoricidal radiation doses,limiting the use of external beam radiation.Because of these limitations,novel percutaneous liver-directed therapies have emerged. The targeted infusion of radioactive microspheres (radioembolization)represents one such therapy. Radioembolization is a minimally invasive transcatheter therapy through which radioactive microspheres are infused into the hepatic arteries that supply tumor. Once infused,these microspheres traverse the hepatic vascular plexus and selectively implant within the tumor arterioles.Embedded within the arterioles, the 90Y impregnated microspheres emit high energy and low penetrating radiation doses selectively to the tumor.Radioembolization has recently shown promise for the treatment of patients with unresectable HCC. The objective of this review article is to highlight twocurrently available radioembolic devices(90Y,188Rh)and provide the reader with a recent review of the literature. | Saad M Ibrahim Robert J Lewandowski Kent T Sato Vanessa L Gates Laura Kulik Mary F Mulcahy Robert K Ryu Reed A Omary Riad Salem | 2008 | World Journal of Gastroenterology2008，14，11： | 14 |
| 5 | Beyond the Pediatric end-stage liver disease system: Solutions for infants with biliary atresia requiring liver transplant显示文摘Biliary atresia(BA), a chronic progressive cholestatic disease of infants, is the leading cause for liver transplant in children, especially in patients under two years of age. BA can be successfully treated with the Kasai portoenterostomy; however most patients still require a liver transplant, with up to one half of BA children needing a transplant by age two. In the current pediatric end-stage liver disease system, children with BA face the risk of not receiving a liver in a safe and timely manner. In this review, we discuss a number of possible solutions to help these children. We focus on two general approaches:(1) preventing/delaying need for transplantation, by optimizing the success of the Kasai operation; and(2) expediting transplantation when needed, by performing techniques other than the standard deceased-donor, whole, ABO-matched organ transplant. | Mary Elizabeth M Tessier Sanjiv Harpavat Ross W Shepherd Girish S Hiremath Mary L Brandt Amy Fisher John A Goss | 2014 | World Journal of Gastroenterology2014，20，32： | 14 |
| 6 | miR-200 family expression is downregulated upon neoplastic progression of Barrett's esophagus显示文摘AIM: To investigate miR-200 family expression in Barrett's epithelium, gastric and duodenal epithelia, and esophageal adenocarcinoma. METHODS: Real-time reverse transcriptase-polymerase chain reaction was used to measure miR-200, ZEB1 and ZEB2 expression. Ingenuity Pathway Analysis of miR-200 targets was used to predict biological outcomes. RESULTS: Barrett's epithelium expressed lower levels of miR-141 and miR-200c than did gastric and duodenal epithelia (P < 0.001). In silico analysis indicated roles for the miR-200 family in molecular pathways that distinguish Barrett's epithelium from gastric and duodenalepithelia, and which control apoptosis and proliferation. All miR-200 members were downregulated in adenocarcinoma (P < 0.02), and miR-200c expression was also downregulated in non-invasive epithelium adjacent to adenocarcinoma (P < 0.02). The expression of all miR-200 members was lower in Barrett's epithelium derived high-grade dysplastic cell lines than in a cell line derived from benign Barrett's epithelium. We observed signif icant inverse correlations between miR-200 family expression and ZEB1 and ZEB2 expression in Barrett's epithelium and esophageal adenocarcinoma (P < 0.05). CONCLUSION: miR-200 expression might contribute to the anti-apoptotic and proliferative phenotype of Barrett's epithelium and regulate key neoplastic processes in this epithelium. | Cameron M Smith David I Watson Mary P Leong George C Mayne Michael Z Michael Bas PL Wijnhoven Damian J Hussey | 2011 | World Journal of Gastroenterology2011，17，8： | 13 |
| 7 | Diffusion-weighted magnetic resonance imaging to predict response of hepatocellular carcinoma to chemoembolization显示文摘AIM: To investigate whether intra-procedural diffusion- weighted magnetic resonance imaging can predict response of hepatocellular carcinoma (HCC) during trans- catheter arterial chemoembolization (TACE). METHODS: Sixteen patients (15 male), aged 59 ±11 years (range: 42-81 years) underwent a total of 21 separate treatments for unresectable HCC in a hybrid magnetic resonance/interventional radiology suite. Ana- tomical imaging and diffusion-weighted imaging (b = 0, 500 s/mm2) were performed on a 1.5-T unit. Tumor enhancement and apparent diffusion coefficient (ADC, mm2/s) values were assessed immediately before and at 1 and 3 mo after TACE. We calculated the percent change (PC) in ADC values at all time points. We compared follow-up ADC values to baseline values using a paired t test (α = 0.05). RESULTS: The intra-procedural sensitivity, specificity, and positive and negative predictive values (%) for detecting a complete or partial 1-mo tumor response using ADC PC thresholds of ±5%, ±10%, and ±15% were 77, 67, 91, and 40; 54, 67, 88, and 25; and 46, 100, 100, and 30, respectively. There was no clear predictive value for the 3-mo follow-up. Compared to baseline, the immediate post-procedure and 1-mo mean ADC values both increased; the latter obtaining statistical significance (1.48 ± 0.29 mm2/s vs 1.65 ± 0.35 × 10-3 mm2/s, P < 0.014). CONCLUSION: Intra-procedural ADC changes of > 15% predicted 1-mo anatomical HCC response with the greatest accuracy, and can provide valuable feedback at the time of TACE. | Johnathan C Chung Neel K Naik Robert J Lewandowski Mary F Mulcahy Laura M Kulik Kent T Sato Robert K Ryu Riad Salem Andrew C Larson Reed A Omary | 2010 | World Journal of Gastroenterology2010，16，25： | 13 |
| 8 | Hepatocellular carcinoma: Review of disease and tumor biomarkers显示文摘Hepatocellular carcinoma(HCC) is a common malignancy and now the second commonest global cause of cancer death. HCC tumorigenesis is relatively silent and patients experience late symptomatic presentation. As the option for curative treatments is limited to early stage cancers, diagnosis in non-symptomatic individuals is crucial. International guidelines advise regular surveillance of high-risk populations but the current tools lack sufficient sensitivity for early stage tumors on the background of a cirrhotic nodular liver. A number of novel biomarkers have now been suggested in the literature, which may reinforce the current surveillance methods. In addition, recent metabonomic and proteomic discoveries have established specific metabolite expressions in HCC, according to Warburg's phenomenon of altered energy metabolism. With clinical validation, a simple and non-invasive test from the serum or urine may be performed to diagnose HCC, particularly benefiting low resource regions where the burden of HCC is highest. | Jin Un Kim Mohamed I F Shariff Mary M E Crossey Maria Gomez-Romero Elaine Holmes I Jane Cox Haddy K S Fye Ramou Njie Simon D Taylor-Robinson | 2016 | World Journal of Hepatology2016，8，10： | 13 |
| 9 | Stem cell mechanisms during left ventricular remodeling post-myocardial infarction:Repair and regeneration显示文摘Post-myocardial infarction(MI),the left ventricle(LV)undergoes a series of events collectively referred to as remodeling.As a result,damaged myocardium is replaced with fibrotic tissue consequently leading to contractile dysfunction and ultimately heart failure.LV remodeling post-MI includes inflammatory,fibrotic,and neovascularization responses that involve regulated cell recruitment and function.Stem cells(SCs)have been transplanted post-MI for treatment of LV remodeling and shown to improve LV function by reduction in scar tissue formation in humans and animal models of MI.The promising results obtained from the application of SCs post-MI have sparked a massive effort to identify the optimal SC for regeneration of cardiomyocytes and the paradigm for clinical applications.Although SC transplantations are generally associated with new tissue formation,SCs also secrete cytokines,chemokines and growth factors that robustly regulate cell behavior in a paracrine fashion during the remodeling process.In this review,the different types of SCs used for cardiomyogenesis,markers of differentiation,paracrine factor secretion,and strategies for cell recruitment and delivery are addressed. | Rogelio Zamilpa Mary M Navarro Iris Flores Sy Griffey | 2014 | World Journal of Cardiology2014，6，7： | 11 |
| 10 | Rifaximin vs conventional oral therapy for hepatic encephalopathy:A meta-analysis显示文摘AIM: To characterize the efficacy of rifaximin in the management of hepatic encephalopathy (HE) as several randomized controlled studies have shown contradictory results on its effectiveness in comparison to other oral agents. METHODS: We performed a systematic review and random effects meta-analysis of all eligible trials identifi ed through electronic and manual searches. Twelve randomized controlled trials met the inclusion criteria with a total of 565 patients. RESULTS: The clinical effectiveness of rifaximin was equivalent to disaccharides or other oral antibiotics[odds ratio (OR) 0.96; 95% CI: 0.94-4.08] but with a better safety profi le (OR 0.27; 95% CI: 0.12-0.59). At the completion of treatment protocols, patients receiving rifaximin showed lower serum ammonia levels [weighted mean difference (WMD) = -10.65; 95% CI: -23.4-2.1; P = 0.10], better mental status (WMD = -0.24; 95% CI: -0.57-0.08; P = 0.15) and less asterixis (WMD -0.1; 95% CI -0.26-0.07; P = 0.25) without reaching statistical signifi cance. On the other hand, other psychometric outcomes such as electroencephalographic response and grades of portosystemic encephalopathy were superior in patients treated with rifaximin in comparison to the control group (WMD = 0.21, 95% CI: -0.33-0.09, P = 0.0004; and WMD = -2.33, 95% CI: -2.68-1.98, P = 0.00001, respectively). Subgroup and sensitivity analysis did not show any signifi cant difference in the above fi ndings. CONCLUSION: Rifaximin appears to be at least as effective as other conventional oral agents for the treatment of HE with a better safety profi le. | Karim M Eltawil Marie Laryea Kevork Peltekian Michele Molinari | 2012 | World Journal of Gastroenterology2012，18，8： | 9 |

| 12 | Resveratrol engages selective apoptotic signals in gastric adenocarcinoma cells显示文摘AIM: To investigate the intracellular apoptotic signals engaged by resveratrol in three gastric adenocarcinoma cancer cell lines, two of which (AGS and SNU-1) express p53 and one (KATO-Ⅲ) with deleted p53. METHODS: Nuclear fragmentation was used to quanti- tate apoptotic cells; caspase activity was determined by photometric detection of cleaved substrates; formation of oxidized cytochrome C was used to measure cytochrome C activity, and Western blot analysis was used to determine protein expression. RESULTS: Gastric cancer cells, irrespective of their p53 status, responded to resveratrol with fragmentation of DNA and cleavage of nuclear lamins A and B and PARP. Resveratrol, however, has no effect on mitochondria-associated apoptotic proteins Bcl-2, Bcl- xl, Bax, Bid or Smac/Diablo, and did not promote sub- cellular redistribution of cytochrome C, indicating that resveratrol-induced apoptosis of gastric carcinoma cells does not require breakdown of mitochondrial membrane integrity. Resveratrol up-regulated p53 protein in SNU-1 and AGS cells but there was a difference in response of intracellular apoptotic signals between these cell lines. SNU-1 cells responded to resveratrol treatment with down-regulation of survivin, whereas in AGS and KATO- Ⅲ cells resveratrol stimulated caspase 3 and cytochrome C oxidase activities. CONCLUSION: These findings indicate that even within a specific cancer the intracellular apoptotic signals engaged by resveratrol are cell type dependent and suggest that such differences may be related to differentiation or lack of differentiation of these cells. | William L Riles Jason Erickson Sanjay Nayyar Mary Jo Atten Bashar M Attar Oksana Holian | 2006 | World Journal of Gastroenterology2006，12，35： | 8 |

| 14 | Sieving characteristics of cytokine-and peroxide-induced epithelial barrier leak:Inhibition by berberine显示文摘AIM:To study whether the inflammatory bowel disease(IBD)colon which exhibits varying severity and cytokine levels across its mucosa create varying types of transepithelial leak.METHODS:We examined the effects of tumor necrosis factor-α(TNF-α),interferon-γ(IFN-γ),interleukin-1-β(IL1β)and hydrogen peroxide(H_2O_2)-singly and in combinations-on barrier function of CACO-2 cell layers.Our focus was on the type(not simply the magnitude)of transepithelial leak generated by these agents as measured by transepithelial electrical resistance(TER)and transepithelial flux of ^(14)C-D-mannitol,3H-Lactulose and ^(14)C-Polyethylene glycol as radiolabeled probe molecules.The isoquinoline alkaloid,berberine,was then examined for its ability to reduce specific types of transepithelial leak.RESULTS:Exposure to TNF-α alone(200 ng/mL;48 h)induced a 50% decrease in TER,i.e.,increased leak of Na^+ and Cl--with only a marginal but statistically significant increase in transepithelial leak of ^(14)C-mannitol(Jm).Exposure to TNF-α + IFN-γ(200 ng/mL;48 h)+ IL1β(50 ng/mL;48 h)did not increase the TER change(from TNF-α alone),but there was now a 100% increase in J_m.There however was no increase in transepithelial leak of two larger probe molecules,~3H-lactulose and ^(14)C-polyethylene glycol(PEG).However,exposure to TNF-α + IFN-γ + IL1β followed by a 5 h exposure to2 mmol/L H_2O_2 resulted in a 500% increase in ^(14)C-PEG leak as well as leak to the luminal mitogen,epidermal growth factor.CONCLUSION:This model of graded transepithelial leak is useful in evaluating therapeutic agents reducing IBD morbidity by reducing barrier leak to various luminal substances. | Katherine M DiGuilio Christina M Mercogliano Jillian Born Brendan Ferraro Julie To Brittany Mixson Allison Smith Mary Carmen Valenzano James M Mullin | 2016 | World Journal of Gastrointestinal Pathophysiology2016，7，2： | 6 |
| 15 | Retrograde-viewing device improves adenoma detection rate in colonoscopies for surveillance and diagnostic workup显示文摘AIM:To determine which patients might benefit most from retrograde viewing during colonoscopy through subset analysis of randomized,controlled trial data.METHODS:The Third Eye Retroscope Randomized Clinical Evaluation(TERRACE) was a randomized,controlled,multicenter trial designed to evaluate the efficacy of a retrograde-viewing auxiliary imaging device that is used during colonoscopy to provide a second video image which allows viewing of areas on the proximal aspect of haustral folds and flexures that are difficult to see with the colonoscope's forward view.We performed a post-hoc analysis of the TERRACE data to determine whether certain subsets of the patient population would gain more benefit than others from use of the device.Subjects were patients scheduled for colonoscopy for screening,surveillance or diagnostic workup,and each underwent same-day tandem examinations with standard colonoscopy(SC) and Third Eye colonoscopy(TEC),randomized to SC followed by TEC or vice versa.RESULTS:Indication for colonoscopy was screening in 176/345 subjects(51.0%),surveillance after previous polypectomy in 87(25.2%) and diagnostic workup in 82(23.8%).In 4 subjects no indication was specified.Previously reported overall results had shown a net additional adenoma detection rate(ADR) with TEC of 23.2% compared to SC.Relative risk(RR) of missing adenomas with SC vs TEC as the initial procedure was 1.92(P = 0.029).Post-hoc subset analysis shows additional ADRs for TEC compared to SC were 4.4% for screening,35.7% for surveillance,55.4% for diagnostic and 40.7% for surveillance and diagnostic combined.The RR of missing adenomas with SC vs TEC was 1.11(P = 0.815) for screening,3.15(P = 0.014) for surveillance,8.64(P = 0.039) for diagnostic and 3.34(P = 0.003) for surveillance and diagnostic combined.Although a multivariate Poisson regression suggested gender as a possibly significant factor,subset analysis showed that the difference between genders was not statistically significant.Age,bowel prep quality and withdrawal time did not significantly affect the RR of missing adenomas with SC vs TEC.Mean sizes of adenomas detected with TEC and SC were similar at 0.59 cm and 0.56 cm,respectively(P = NS).CONCLUSION:TEC allows detection of significantly more adenomas compared to SC in patients undergoing surveillance or diagnostic workup,but not in screening patients(ClinicalTrials.gov Identifier:NCT01044732). | Peter D Siersema Amit Rastogi Anke M Leufkens Paul A Akerman Kassem Azzouzi Richard I Rothstein Frank P Vleggaar Alessandro Repici Giacomo Rando Patrick I Okolo Olivier Dewit Ana Ignjatovic Elizabeth Odstrcil James East Pierre H Deprez Brian P Saunders Anthony N Kalloo Bradley Creel Vikas Singh Anne Marie Lennon Daniel C DeMarco | 2012 | World Journal of Gastroenterology2012，18，26： | 6 |
| 16 | Molecular detection of Helicobacter pylori antibiotic resistance in stool vs biopsy samples显示文摘AIM To compare(1) demographics in urea breath test(UBT) vs endoscopy patients; and(2) the molecular detection of antibiotic resistance in stool vs biopsy samples.METHODS Six hundred and sixteen adult patients undergoing endoscopy or a UBT were prospectively recruited to the study. The Geno Type Helico DR assay was used to detect Helicobacter pylori(H. pylori) and antibiotic resistance using biopsy and/or stool samples from CLOpositive endoscopy patients and stool samples from UBT-positive patients. RESULTS Infection rates were significantly higher in patients referred for a UBT than endoscopy(overall rates: 33% vs 19%; treatment-na?ve patients: 33% vs 14.7%, respectively). H. pylori-infected UBT patients were younger than H. pylori-infected endoscopy patients(41.4 vs 48.4 years, respectively, P < 0.005), with a higher percentage of H. pylori-infected males in the endoscopy-compared to the UBT-cohort(52.6% vs 33.3%, P = 0.03). The Geno Type Helico DR assay was more accurate at detecting H. pylori infection using biopsy samples than stool samples [98.2%(n = 54/55) vs 80.3%(n =53/66), P < 0.005]. Subset analysis using stool and biopsy samples from CLO-positive endoscopy patients revealed a higher detection rate ofresistance-associated mutations using stool samples compared to biopsies. The concordance rates between stool and biopsy samples for the detection of H. pylori DNA, clarithromycin and fluoroquinolone resistance were just 85%, 53% and 35%, respectively. CONCLUSION Differences between endoscopy and UBT patients provide a rationale for non-invasive detection of H. pylori antibiotic resistance. However, the Geno Type Helico DR assay is an unsuitable approach. | Denise E Brennan Joseph Omorogbe Mary Hussey Donal Tighe Grainne Holleran Colm O'Morain Sinéad M Smith Deirdre McNamara | 2016 | World Journal of Gastroenterology2016，22，41： | 6 |
| 17 | Antioxidant Effect of Sepia Ink Extract on Extrahepatic Cholestasis Induced by Bile Duct Ligation in Rats显示文摘Objective The aim of our study was to assess the complications of hepatic fibrosis associated with bile duct ligation and the potential curative role of sepia ink extract in hepatic damage induced by bile duct ligation. Methods Rattus norvegicus rats were divided into 3 groups: Sham-operated group, model rats that underwent common bile duct ligation(BDL), and BDL rats treated orally with sepia ink extract(200 mg/kg body weight) for 7, 14, and 28 d after BDL. Results There was a significant reduction in hepatic enzymes, ALP, GGT, bilirubin levels, and oxidative stress in the BDL group after treatment with sepia ink extract. Collagen deposition reduced after sepia ink extract treatment as compared to BDL groups, suggesting that the liver was repaired. Histopathological examination of liver treated with sepia ink extract showed moderate degeneration in the hepatic architecture and mild degeneration in hepatocytes as compared to BDL groups. Conclusion Sepia ink extract provides a curative effect and an antioxidant capacity on BDL rats and could ameliorate the complications of liver cholestasis. | Hanan Saleh Amel M Soliman Ayman S Mohamed Mohamed-Assem S Marie | 2015 | Biomedical and Environmental Sciences2015，28，8： | 6 |
| 18 | Cryopreservation for delayed circulating tumor cell isolation is a valid strategy for prognostic association of circulating tumor cells in gastroesophageal cancer显示文摘AIM To demonstrate the feasibility of cryopreservation of peripheral blood mononuclear cells(PBMCs) for prognostic circulating tumor cell(CTC) detection in gastroesophageal cancer.METHODS Using 7.5 m L blood samples collected in EDTA tubes from patients with gastroesopheagal adenocarcinoma, CTCs were isolated by epithelial cell adhesion molecule based immunomagnetic capture using the Iso Flux platform. Paired specimens taken during the same blood draw(n = 15) were used to compare number of CTCs isolated from fresh and cryopreserved PBMCs. Blood samples were processed within 24 h to recover the PBMC fraction, with PBMCs used for fresh analysis immediately processed for CTC isolation. Cryopreservation of PBMCs lasted from 2 wk to 25.2 mo(median 14.6 mo). CTCs isolated from pre-treatment cryopreserved PBMCs(n = 43) were examined for associations with clinicopathological variables and survival outcomes.RESULTS While there was a significant trend to a decrease in CTC numbers associated with cryopreserved specimens(mean number of CTCs 34.4 vs 51.5, P = 0.04), this was predominately in samples with a total CTC count of > 50, with low CTC count samples less affected(P = 0.06). There was no significant association between the duration of cryopreservation and number of CTCs. In cryopreserved PBMCs from patient samples prior to treatment, a high CTC count(> 17) was associated with poorer overall survival(OS)(n = 43, HR = 4.4, 95%CI: 1.7-11.7, P = 0.0013). In multivariate analysis, after controlling for sex, age, stage, ECOG performance status, and primary tumor location, a high CTC count remained significantly associated with a poorer OS(HR = 3.7, 95%CI: 1.2-12.4, P = 0.03). CONCLUSION PBMC cryopreservation for delayed CTC isolation is a valid strategy to assist with sample collection, transporting and processing. | Daniel Brungs David Lynch Alison WS Luk Elahe Minaei Marie Ranson Morteza Aghmesheh Kara L Vine Martin Carolan Mouhannad Jaber Paul de Souza Therese M Becker | 2018 | World Journal of Gastroenterology2018，24，7： | 5 |

| 20 | Urinary nuclear magnetic resonance spectroscopy of a Bangladeshi cohort with hepatitis-B hepatocellular carcinoma: A biomarker corroboration study显示文摘AIM: To establish if a distinct urinary metabolic profile could be identified in Bangladeshi hepatitis-B hepatocellular carcinoma(HCC) patients compared to cirrhosis patients and controls. METHODS: Urine samples from 42 Bangladeshi patients with HCC(39 patients with hepatitis-B HCC), 47 with cirrhosis on a background of hepatitis B, 46 with chronic hepatitis B, and seven ethnically-matched healthy controls were analyzed using nuclear magnetic resonance(NMR) spectroscopy. A full dietary and medication history was recorded for each subject. The urinary NMR data were analyzed using principal component analysis(PCA) and orthogonal partial leastsquared discriminant analysis(OPLS-DA) techniques. Differences in relative signal levels of the most discriminatory metabolites identified by PCA and OPLSDA were compared between subject groups using an independent samples Kruskal-Wallis one-way analysis of variance(ANOVA) test with all pairwise multiple comparisons. Within the patient subgroups, the MannWhitney U test was used to compare metabolite levels depending on hepatitis B e-antigen(HBe Ag) status and treatment with anti-viral therapy. A BenjaminiHochberg adjustment was applied to acquire the level of significance for multiple testing, with a declared level of statistical significance of P < 0.05.RESULTS: There were significant differences in age(P < 0.001), weight(P < 0.001), and body mass index(P < 0.001) across the four clinical subgroups. Serum alanine aminotransferase(ALT) was significantly higher in the HCC group compared to controls(P < 0.001); serum α-fetoprotein was generally markedly elevated in HCC compared to controls; and serum creatinine levels were significantly reduced in the HCC group compared to the cirrhosis group(P = 0.004). A threefactor PCA scores plot showed clustering of the urinary NMR spectra from the four subgroups. Metabolites that contributed to the discrimination between the subgroups included acetate, creatine, creatinine, dimethyamine(DMA), formate, glycine, hippurate, and trimethylamine-N-oxide(TMAO). A comparison of relative metabolite levels confirmed that carnitine was significantly increased in HCC; and creatinine, hippurate, and TMAO were significantly reduced in HCC compared to the other subgroups. HBe Ag negative patients showed a significant increase in creatinine(P = 0.001) compared to HBe Ag positive patients in the chronic hepatitis B subgroup, whilst HBe Ag negative patients showed a significant decrease in DMA(P = 0.004) in the cirrhosis subgroup compared to HBe Ag positive patients. There were no differences in metabolite levels in HCC patients who did or did not receive antiviral treatment. CONCLUSION: Urinary NMR changes in Bangladeshi HCC were identified, corroborating previous findings from Egypt and West Africa. These findings could form the basis for the development of a cost-effective HCC dipstick screening test. | I Jane Cox Abil E Aliev Mary ME Crossey Mahvish Dawood Mamun Al-Mahtab Sheikh M Akbar Salimur Rahman Antonio Riva Roger Williams Simon D Taylor-Robinson | 2016 | World Journal of Gastroenterology2016，22，16： | 4 |
