| 1 | Golgi protein-73:A biomarker for assessing cirrhosis and prognosis of liver disease patients显示文摘BACKGROUND Reliable biomarkers of cirrhosis,hepatocellular carcinoma(HCC),or progression of chronic liver diseases are missing.In this context,Golgi protein-73(GP73)also called Golgi phosphoprotein-2,was originally defined as a resident Golgi type II transmembrane protein expressed in epithelial cells.As a result,GP73 expression was found primarily in biliary epithelial cells,with only slight detection in hepatocytes.However,in patients with acute or chronic liver diseases and especially in HCC,the expression of GP73 is significantly up-regulated in hepatocytes.So far,few studies have assessed GP73 as a diagnostic or prognostic marker of liver fibrosis and disease progression.AIM To assess serum GP73 efficacy as a diagnostic marker of cirrhosis and/or HCC or as predictor of liver disease progression.METHODS GP73 serum levels were retrospectively determined by a novel GP73 ELISA(QUANTA Lite®GP73,Inova Diagnostics,Inc.,Research Use Only)in a large cohort of 632 consecutive patients with chronic viral and non-viral liver diseases collected from two tertiary Academic centers in Larissa,Greece(n=366)and Debrecen,Hungary(n=266).Aspartate aminotransferase(AST)/Platelets(PLT)ratio index(APRI)was also calculated at the relevant time points in all patients.Two hundred and three patients had chronic hepatitis B,183 chronic hepatitis C,198 alcoholic liver disease,28 autoimmune cholestatic liver diseases,15 autoimmune hepatitis,and 5 with other liver-related disorders.The duration of follow-up was 50(57)mo[median(interquartile range)].The development of cirrhosis,liver decompensation and/or HCC during follow-up were assessed according to internationally accepted guidelines.In particular,the surveillance for the development of HCC was performed regularly with ultrasound imaging and alpha-fetoprotein(AFP)determination every 6 mo in cirrhotic and every 12 mo in non-cirrhotic patients.RESULTS Increased serum levels of GP73(>20 units)were detected at initial evaluation in 277 out of 632 patients(43.8%).GP73-seropositivity correlated at baseline with the presence of cirrhosis(96.4%vs 51.5%,P<0.001),decompensation of cirrhosis(60.3%vs 35.5%,P<0.001),presence of HCC(18.4%vs 7.9%,P<0.001)and advanced HCC stage(52.9%vs 14.8%,P=0.002).GP73 had higher diagnostic accuracy for the presence of cirrhosis compared to APRI score[Area under the curve(AUC)(95%CI):0.909(0.885-0.934)vs 0.849(0.813-0.886),P=0.003].Combination of GP73 with APRI improved further the accuracy(AUC:0.925)compared to GP73(AUC:0.909,P=0.005)or APRI alone(AUC:0.849,P<0.001).GP73 levels were significantly higher in HCC patients compared to non-HCC[22.5(29.2)vs 16(20.3)units,P<0.001)and positively associated with BCLC stage[stage 0:13.9(10.8);stage A:17.1(16.8);stage B:19.6(22.3);stage C:32.2(30.8);stage D:45.3(86.6)units,P<0.001]and tumor dimensions[very early:13.9(10.8);intermediate:19.6(18.4);advanced:29.1(33.6)units,P=0.004].However,the discriminative ability for HCC diagnosis was relatively low[AUC(95%CI):0.623(0.570-0.675)].Kaplan-Meier analysis showed that the detection of GP73 in patients with compensated cirrhosis at baseline,was prognostic of higher rates of decompensation(P=0.036),HCC development(P=0.08),and liver-related deaths(P<0.001)during follow-up.CONCLUSION GP73 alone appears efficient for detecting cirrhosis and superior to APRI determination.In combination with APRI,its diagnostic performance can be further improved.Most importantly,the simple GP73 measurement proved promising for predicting a worse outcome of patients with both viral and nonviral chronic liver diseases. | Nikolaos K Gatselis Tamás Tornai Zakera Shums Kalliopi Zachou Asterios Saitis Stella Gabeta Roger Albesa Gary L Norman Mária Papp George N Dalekos | 2020 | World Journal of Gastroenterology2020，26，34： | 21 |

| 3 | Randomized trial in malignant biliary obstruction:Plastic vs partially covered metal stents显示文摘AIM:To compare efficacy and complications of par-tially covered self-expandable metal stent(pcSEMS)to plastic stent(PS)in patients treated for malignant,infrahilar biliary obstruction.METHODS:Multicenter prospective randomized clinical trial with treatment allocation to a pcWallstent(SEMS)or a 10 French PS.Palliative patients aged≥18,for infrahilar malignant biliary obstruction and a Karnofsky performance scale index>60%from 6 participating North American university centers.Primary endpoint was time to stent failure,with secondary outcomes of death,adverse events,Karnofsky performance score and short-form-36 scale administered on a three-monthly basis for up to 2 years.Survival analyses were performed for stent failure and death,with Cox proportional hazards regression models to determine significant predictive characteristics.RESULTS:Eighty-five patients were accrued over 37mo,42 were randomized to the SEMS group and 83patients were available for analyses.Time to stent failure was 385.3±52.5 d in the SEMS and 153.3±19.8 d in the PS group,P=0.006.Time to death did not differ between groups(192.3±23.4 d for SEMS vs211.5±28.0 d for PS,P=0.70).The only significant predictor was treatment allocation,relating to the time to stent failure(P=0.01).Amongst other measured outcomes,only cholangitis differed,being more common in the PS group(4.9%vs 24.5%,P=0.029).The small number of patients in follow-up limits longitudinal assessments of performance and quality of life.From an initially planned 120 patients,only 85 patients were recruited.CONCLUSION:Partially covered SEMS result in a longer duration till stent failure without increased complication rates,yet without accompanying measurable benefits in survival,performance,or quality of life. | Peter L Moses Khalid M AlNaamani Alan N Barkun Stuart R Gordon Roger D Mitty M Stanley Branch Thomas E Kowalski Myriam Martel Viviane Adam | 2013 | World Journal of Gastroenterology2013，19，46： | 6 |

| 5 | Physical activity after total knee arthroplasty: A critical review显示文摘Total knee arthroplasty(TKA) is the most commonly performed elective surgery in the United States. TKA typically improves functional performance and reduces pain associated with knee osteoarthritis. Little is known about the influence of TKA on overall physical activity levels. Physical activity, defined as 'any bodily movement produced by skeletal muscles that results in energy expenditure', confers many health benefits but typically decreases with endstage osteoarthritis. The purpose of this review is to describe the potential benefits(metabolic, functional, and orthopedic) of physical activity to patients undergoing TKA, present results from recent studies aimed to determine the effect of TKA on physical activity, and discuss potential sources of variability and conflicting results for physical activity outcomes. Several studies utilizing self-reported outcomes indicate that patients perceive themselves to be more physically active after TKA than they were before surgery. Accelerometry-based outcomes indicate that physical activity for patients after TKA remains at or below pre-surgical levels. Several different factors likely contributed to these variable results, including the use of different instruments, duration of follow-up, and characteristics of the subjects studied. Comparison to norms, however, suggests that daily physical activity for patients following TKA may fall short of healthy agematched controls. We propose that further study of the relationship between TKA and physical activity needs to be performed using accelerometry-based outcome measures at multiple post-surgical time points. | Roger J Paxton Edward L Melanson Jennifer E Stevens-Lapsley Cory L Christiansen | 2015 | World Journal of Orthopedics2015，6，8： | 5 |
| 6 | Review of primary sclerosing cholangitis with increased IgG4 levels显示文摘Primary sclerosing cholangitis(PSC) is a chronic progressive liver disease. Subtypes of PSC have been described, most recently PSC with elevated serum and/or tissue IgG4 subclass. We aim to summarise the clinical phenotype,disease associations, differential diagnosis, response to therapy and pathogenic mechanisms underlying PSC-high IgG4 subtype. We reviewed Pub Med,MEDLINE and Embase with the search terms 'primary sclerosing cholangitis','IgG4', and 'IgG4-related sclerosing cholangitis(IgG4-SC)'. Elevated serum IgG4 are found in up-to one-quarter, and abundant IgG4-plasma cell infiltrates in the liver and bile ducts are found in up-to one-fifth of PSC patients. This group have a distinct clinical phenotype, with some studies reporting a more aggressive course of liver and associated inflammatory bowel disease, compared to PSCnormal IgG4 and the disease mimic IgG4-SC. Distinguishing PSC-high IgG4 from IgG4-SC remains challenging, requiring careful assessment of clinical features,organ involvement and tissue morphology. Calculation of serum IgG4:IgG1 ratios and use of a novel IgG4:IgG RNA ratio have been reported to have excellent specificity to distinguish IgG4-SC and PSC-high IgG4 but require validation in larger cohorts. A role for corticosteroid therapy in PSC-high IgG4 remains unanswered, with concerns of increased toxicity and lack of outcome data. The immunological drivers underlying prominent IgG4 antibodies in PSC are incompletely defined. An association with PSC-high IgG4 and HLA class-II haplotypes(B*07, DRB1*15), T-helper2 and T-regulatory cytokines(IL4, IL10,IL13) and chemokines(CCL1, CCR8) have been described. PSC-high IgG4 have a distinct clinical phenotype and need careful discrimination from IgG4-SC,although response to immunosuppressive treatments and long-term outcome remains unresolved. The presence of IgG4 likely represents chronic activation to persistent antigenic exposure in genetically predisposed individuals. | Charis D Manganis Roger W Chapman Emma L Culver | 2020 | World Journal of Gastroenterology2020，26，23： | 5 |

| 9 | One stop shop:backbones trees for important phytopathogenic genera:Ⅰ(2014)显示文摘Many fungi are pathogenic on plants and cause significant damage in agriculture and forestry.They are also part of the natural ecosystem and may play a role in regulating plant numbers/density.Morphological identification and analysis of plant pathogenic fungi,while important,is often hampered by the scarcity of discriminatory taxonomic characters and the endophytic or inconspicuous nature of these fungi.Molecular(DNA sequence)data for plant pathogenic fungi have emerged as key information for diagnostic and classification studies,although hampered in part by non-standard laboratory practices and analytical methods.To facilitate current and future research,this study provides phylogenetic synopses for 25 groups of plant pathogenic fungi in the Ascomycota,Basidiomycota,Mucormycotina(Fungi),and Oomycota,using recent molecular data,up-to-date names,and the latest taxonomic insights.Lineagespecific laboratory protocols together with advice on their application,as well as general observations,are also provided.We hope to maintain updated backbone trees of these fungal lineages over time and to publish them jointly as new data emerge.Researchers of plant pathogenic fungi not covered by the present study are invited to join this future effort.Bipolaris,Botryosphaeriaceae,Botryosphaeria,Botrytis,Choanephora,Colletotrichum,Curvularia,Diaporthe,Diplodia,Dothiorella,Fusarium,Gilbertella,Lasiodiplodia,Mucor,Neofusicoccum,Pestalotiopsis,Phyllosticta,Phytophthora,Puccinia,Pyrenophora,Pythium,Rhizopus,Stagonosporopsis,Ustilago and Verticillium are dealt with in this paper. | Kevin D.Hyde R.Henrik Nilsson S.Aisyah Alias Hiran A.Ariyawansa Jaime E.Blair Lei Cai Arthur W.A.M.de Cock Asha J.Dissanayake Sally L.Glockling Ishani D.Goonasekara Michal Gorczak Matthias Hahn Ruvishika S.Jayawardena Jan A.L.van Kan Matthew H.Laurence C.AndréLévesque Xinghong Li Jian-Kui Liu Sajeewa S.N.Maharachchikumbura Dimuthu S.Manamgoda Frank N.Martin Eric H.C.McKenzie Alistair R.McTaggart Peter E.Mortimer Prakash V.R.Nair Julia Pawlowska Tara L.Rintoul Roger G.Shivas Christoffel F.J.Spies Brett A.Summerell Paul W.J.Taylor Razak B.Terhem Dhanushka Udayanga Niloofar Vaghefi Grit Walther Mateusz Wilk Marta Wrzosek Jian-Chu Xu JiYe Yan Nan Zhou | 2014 | Fungal Diversity2014，，4： | 3 |
| 10 | Liver fat deposition and mitochondrial dysfunction in morbid obesity:An approach combining metabolomics with liver imaging and histology显示文摘AIM: To explore the usefulness of magnetic resonance imaging(MRI) and spectroscopy(MRS) for assessment of non-alcoholic fat liver disease(NAFLD) as compared with liver histological and metabolomics findings. METHODS: Patients undergoing bariatric surgery following procedures involved in laparoscopic sleeve gastrectomy were recruited as a model of obesityinduced NAFLD in an observational, prospective, singlesite, cross-sectional study with a pre-set duration of 1 year. Relevant data were obtained prospectively and surrogates for inflammation, oxidative stress and lipid and glucose metabolism were obtained through standard laboratory measurements. To provide reliable data from MRI and MRS, novel procedures were designed to limit sampling variability and other sources of error using a 1.5T Signa HDx scanner and protocols acquired from the 3D or 2D Fat SAT FIESTA prescription manager. We used our previously described 1H NMRbased metabolomics assays. Data were obtained immediately before surgery and after a 12-mo period including histology of the liver and measurement of metabolites. Values from 1H NMR spectra obtained after surgery were omitted due to technical limitations.RESULTS: MRI data showed excellent correlation with the concentration of liver triglycerides, other hepatic lipid components and the histological assessment, w h i c h e xc l u d e d t h e p r e s e n c e o f n o n-a l c o h o l i c steatohepatitis(NASH). MRI was sufficient to follow up NAFLD in obese patients undergoing bariatric surgery and data suggest usefulness in other clinical situations. The information provided by MRS replicated that obtained by MRI using the-CH3 peak(0.9 ppm), the-CH2- peak(1.3 ppm, mostly triglyceride) and the-CH=CH- peak(2.2 ppm). No patient depicted NASH. After surgery all patients significantly decreased their body weight and steatosis was virtually absent even in patients with previous severe disease. Improvement was also observed in the serum concentrations of selected variables. The most relevant findings using metabolomics indicate increased levels of triglyceride and monounsaturated fatty acids in severe steatosis but those results were accompanied by a significant depletion of diglycerides, polyunsaturated fatty acids, glucose-6-phosphate and the ATP/AMP ratio. Combined data indicated the coordinated action on mitochondrial fat oxidation and glucose transport activity and may support the consideration of NAFLD as a likely mitochondrial disease. This concept may helpto explain the dissociation between excess lipid storage in adipose tissue and NAFLD and may direct the search for plasma biomarkers and novel therapeutic strategies. A limitation of our study is that data were obtained in a relatively low number of patients.CONCLUSION: MRI is sufficient to stage NAFLD in obese patients and to assess the improvement after bariatric surgery. Other data were superfluous for this purpose. | Nahum Calvo Raúl Beltrán-Debón Esther Rodríguez-Gallego Anna Hernández-Aguilera Maria Guirro Roger Mariné-Casadó Lidón Millá Josep M Alegret Fàtima Sabench Daniel del Castillo María Vinaixa Miguelàngel Rodríguez Xavier Correig Roberto García-álvarez Javier A Menendez Jordi Camps Jorge Joven | 2015 | World Journal of Gastroenterology2015，21，24： | 2 |

| 13 | Thermal hypersensitivity in a subset of irritable bowel syndrome patients显示文摘AIM:To characterize thermal hypersensitivity in patients with constipation-and diarrhea-predominant irritable bowel syndrome (IBS).METHODS:Thermal pain sensitivity was tested among patients with diarrhea-predominant IBS (D-IBS) and constipation-predominant IBS (C-IBS) compared to healthy subjects.A total of 42 patients (29 female and 13 male;mean age 27.0±6.4 years) with D-IBS;24 patients (16 female and eight male;mean age 32.5±8.8 years) with C-IBS;and 52 control subjects (34 female and 18 male;mean age 27.3±8.0 years) participated in the study.Thermal stimuli were delivered using a Medoc Thermal Sensory Analyzer with a 3 cm × 3 cm surface area.Heat pain threshold (HPTh) and heat pain tolerance (HPTo) were assessed on the left ventral forearm and left calf using an ascending method of limits.The Functional Bowel Disease Severity Index (FBDSI) was also obtained for all subjects.RESULTS:Controls were less sensitive than C-IBS and D-IBS (both at P < 0.001) with no differences between C-IBS and D-IBS for HPTh and HPTo.Thermal hyperalgesia was present in both groups of IBS patients relative to controls,with IBS patients reporting significantly lower pain threshold and pain tolerance at both test sites.Cluster analysis revealed the presence of subgroups of IBS patients based on thermal hyperalgesia.One cluster (17% of the sample) showed a profile of heat pain sensitivity very similar to that of healthy controls;a second cluster (47% of the sample) showed moderate heat pain sensitivity;and a third cluster (36% of the sample) showed a very high degree of thermal hyperalgesia.CONCLUSION:A subset of IBS patients had thermal hypersensitivity compared to controls,who reported significantly lower HPTh and HPTo.All IBS patients had a higher score on the FBDSI than controls.Interestingly,the subset of IBS patients with high thermal sensitivity (36%) had the highest FBDSI score compared to the other two groups of IBS patients. | QiQi Zhou Roger B Fillingim Joseph L Riley Ⅲ G Nicholas Verne | 2009 | World Journal of Gastroenterology2009，15，26： | 2 |

| 17 | Evolving role of magnetic resonance techniques in primary sclerosing cholangitis显示文摘Development of non-invasive methods to risk-stratify patients and predict clinical endpoints have been identified as one of the key research priorities in primary sclerosing cholangitis(PSC). In addition to serum and histological biomarkers, there has been much recent interest in developing imaging biomarkers that can predict disease course and clinical outcomes in PSC.Magnetic resonance imaging/magnetic resonance cholangiopancreatography(MRI/MRCP) continue to play a central role in the diagnosis and follow-up of PSC patients. Magnetic resonance(MR) techniques have undergone significant advancement over the last three decades both in MR data acquisition and interpretation. The progression from a qualitative to quantitative approach in MR acquisition techniques and data interpretation, offers the opportunity for the development of objective and reproducible imaging biomarkers that can potentially be incorporated as an additional endpoint in clinical trials. This review article will discuss how the role of MR techniques have evolved over the last three decades from emerging as an alternative diagnostic tool to endoscopic retrograde cholangiopancreatography, to being instrumental in the ongoing search for imaging biomarker of disease stage, progression and prognosis in PSC. | Emmanuel A Selvaraj Emma L Culver Helen Bungay Adam Bailey Roger W Chapman Michael Pavlides | 2019 | World Journal of Gastroenterology2019，25，6： | 2 |
| 18 | Suppressing tawny crazy ant (Nylanderia fulva) by RNAi technology显示文摘A bstract The tawny crazy ant(Nylanderia fulva)is a new invasive pest in the United States.At present,its management mainly relies on the use of synthetic insecticides,which are generally ineffective at producing lasting control of the pest,necessitating alternative environmentally friendly measures.In this study,we evaluated the feasibility of gene silencing to control this ant species.Six housekeeping genes encoding actin(NfActin),coatomer subunit β (NfCOPP),arginine kinase(NfArgK),and V-type proton ATPase subunits A(NfvATPaseA),B(NfvATPaseB)and E(NfvATPaseE)were cloned.Phylogenetic analysis revealed high sequence similarity to homologs from other ant species,particularly the Florida carpenter ant(Camponotus floridanus).To silence these genes,vector L4440 was used to generate six specific RNAi constructs for bacterial expression.Heat-inactivated,dsRNA-expressing Escherichia coli were incorporated into artificial diet.Worker ants exhibited reduced endogenous gene expression after feeding on such diet for 9 d.However,only ingestion of dsRNAs of NfCOPfi(a gene involved in protein trafficking)and NfArgK(a cellular energy reserve regulatory gene in invertebrates)caused modest but significantly higher ant mortality than the control.These results suggest that bacterially expressed dsRNA can be orally delivered to ant cells as a mean to target its vulnerabilities.Improved efficacy is necessary for the RNAi-based approach to be useful in tawny crazy ant management. | Jia Meng Jiaxin Lei Andrew Davitt Jocelyn RHolt Jian Huang Roger Gold Edward L Vargo Aaron MTarone Keyan Zhu-Salzman | 2020 | Insect Science2020，27，1： | 2 |
