2Spectrum of anemia associated with chronic liver disease显示文摘Anemia of diverse etiology is a common complication of chronic liver diseases. The causes of anemia include acute or chronic gastrointestinal hemorrhage, and hypersplenism secondary to portal hypertension. Severe hepatocellular disease predisposes to hemorrhage because of impaired blood coagulation caused by deficiency of blood coagulation factors synthesized by hepatocytes, and/or thrombocytopenia. Aplastic anemia, which is characterized by pancytopenia and hypocellular bone marrow, may follow the development of hepatitis. Its presentation includes progressive anemia and hemorrhagic manifestations. Hematological complications of combination therapy for chronic viral hepatitis include clinically signif icant anemia, secondary to treatment with ribavirin and/or interferon. Ribavirininduced hemolysis can be reversed by reducing the dose of the drug or discontinuing it altogether. Interferons may contribute to anemia by inducing bone marrow suppression. Alcohol ingestion is implicated in the pathogenesis of chronic liver disease and may contribute to associated anemia. In patients with chronic liver disease, anemia may be exacerbated by defi ciency of folic acid and/or vitamin B12 that can occur secondary to inadequate dietary intake or malabsorption.Rosario Gonzalez-Casas E Anthony Jones Ricardo Moreno-Otero 2009World Journal of Gastroenterology2009,15,37:13
3柑桔黄龙病的鉴定和柯赫氏定理(英文)显示文摘黄龙(梢)病被认为是世界柑橘生产上的毁灭性病害已超过一个世纪,但该病害的病原学至今还没有清晰地建立起来。根据16S rRNA基因序列分析,一组被称为'Candidatus Liberibacter species'的难培养细菌被认为与黄龙病相关。然而,要确定'Ca.Liberibacter spp.'是黄龙病病原的柯赫氏定理并没有真正完成。令我们担忧的是,近年来有些文献频频指出'Ca.Liberibacter spp.'是黄龙病的病原,其实该细菌与柑橘寄主的直接病理反应还没有完全确定。我们建议,在黄龙病病原学清楚之前,文献报道在这方面需要有准确的阐述。Chen J Deng X Civerolo E L Lee R F Jones J B Zhou C Hartung J S Manjunath K L Brlansky R H 2011植物病理学报2011,41,2:10
4Liver disease and erythropoietic protoporphyria:A concise review显示文摘The porphyries are a group of metabolic disorders characterized by deficiencies in the activity of enzymes involved in the biosynthesis of heme.In erythropoietic protoporphyria(EPP),in the majority of cases an autosomal dominant disease,there is a mutation of the gene that encodes ferrochelatase(FECH).FECH deficiency is associated with increased concentrations of protoporphyrin in erythrocytes,plasma,skin and liver.The prevalence of this inherited disorder oscillates between 1:75 000 and 1:200 000.Clinical manifestations of EPP appear in early infancy upon first exposure to the sun.Nevertheless,approximately 5%-20% of patients with EPP develop liver manifestations.Retention of protoporphyrin in the liver is associated with cholestatic phenomena and oxidative stress that predisposes to hepatobiliary disease of varying degrees of severity,such as cholelithiasis,mild parenchymal liver disease,progressive hepatocellular disease with end-stage liver disease and acute liver failure.Liver damage is the major risk in EPP patients,so surveillance and frequent clinical and biochemical liver follow-up is mandatory.The diagnostic approach consists in detecting increased levels of protoporphyrin,decreased activity of FECH and genetic analysis of the FECH gene.A variety of nonsurgical therapeutic approaches have been adopted for the management of EPP associated with liver disease,but none of these has been shown to be unequivocally efficacious.Nevertheless,some may have a place in preparing patients for liver transplantation.Liver transplantation does not correct the constitutional deficiency of FECH.Consequently,there is a risk of recurrence of liver disease after liver transplantation as a result of continuing overproduction of protoporphyrin.Some authors recommend that bone marrow transplantation should be considered in liver allograft recipients to prevent recurrence of hepatic disease.María José Casanova-González María Trapero-Marugán E Anthony Jones Ricardo Moreno-Otero 2010World Journal of Gastroenterology2010,16,36:7

7Gastric emptying, postprandial blood pressure, glycaemia and splanchnic flow in Parkinson's disease显示文摘AIM: To determine gastric emptying, blood pressure, mesenteric artery blood flow, and blood glucose responses to oral glucose in Parkinson's disease. METHODS: Twenty-one subjects(13 M, 8 F; age 64.2 ± 1.6 years) with mild to moderate Parkinson's disease(Hoehn and Yahr score 1.4 ± 0.1, duration of known disease 6.3 ± 0.9 years) consumed a 75 g glucose drink, labelled with 20 MBq 99mTc-calcium phytate. Gastric emptying was quantified with scintigraphy, blood pressure and heart rate with an automated device, superior mesenteric artery blood flow by Doppler ultrasonography and blood glucose byglucometer for 180 min. Autonomic nerve function was evaluated with cardiovascular reflex tests and upper gastrointestinal symptoms by questionnaire. RESULTS: The mean gastric half-emptying time was 106 ± 9.1 min, gastric emptying was abnormally delayed in 3 subjects(14%). Systolic and diastolic blood pressure fell(P < 0.001) and mesenteric blood flow and blood glucose(P < 0.001 for both) increased, following the drink. Three subjects(14%) had definite autonomic neuropathy and 8(38%) had postprandial hypotension. There were no significant relationships between changes in blood pressure, heart rate or mesenteric artery blood flow with gastric emptying. Gastric emptying was related to the score for autonomic nerve function(R = 0.55, P < 0.01). There was an inverse relationship between the blood glucose at t = 30 min(R =-0.52, P < 0.05), while the blood glucose at t = 180 min was related directly(R = 0.49, P < 0.05), with gastric emptying. CONCLUSION: In mild to moderate Parkinson's disease, gastric emptying is related to autonomic dysfunction and a determinant of the glycaemic response to oral glucose.Laurence G Trahair Thomas E Kimber Katerina Flabouris Michael Horowitz Karen L Jones 2016World Journal of Gastroenterology2016,22,20:5

11Macrophage secretory products induce an inflammatory phenotype in hepatocytes显示文摘AIM:To investigate the influence of macrophages on hepatocyte phenotype and function.METHODS:Macrophages were differentiated from THP-1 monocytes via phorbol myristate acetate stimulation and the effects of monocyte or macrophageconditioned medium on HepG2 mRNA and protein expression determined.The in vivo relevance of these findings was confirmed using liver biopsies from 147 patients with hepatitis C virus(HCV)infection.RESULTS:Conditioned media from macrophages,but not monocytes,induced a transient morphological change in hepatocytes associated with upregulation of vimentin(7.8±2.5-fold,P=0.045)and transforming growth factor(TGF)-β1(2.6±0.2-fold,P<0.001)and downregulation of epithelial cadherin(1.7±0.02-fold,P=0.017)mRNA expression.Microarray analysis revealed significant upregulation of lipocalin-2(17-fold,P <0.001)and pathways associated with inflammation,and substantial downregulation of pathways related to hepatocyte function.In patients with chronic HCV,realtime polymerase chain reaction and immunohistochemistry confirmed an increase in lipocalin-2 mRNA(F0 1.0 ±0.3,F1 2.2±0.2,F2 3.0±9.3,F3/4 4.0±0.8,P= 0.003)and protein expression(F1 1.0±0.5,F2 1.3± 0.4,F3/4 3.6±0.4,P=0.014)with increasing liver injury.High performance liquid chromatography-tandem mass spectrometry analysis identified elevated levels of matrix metalloproteinase(MMP)-9 in macrophageconditioned medium,and a chemical inhibitor of MMP-9 attenuated the change in morphology and mRNA expression of TGF-β1(2.9±0.2 vs 1.04±0.1,P<0.001) in macrophage-conditioned media treated HepG2 cells.In patients with chronic HCV infection,hepatic mRNA expression of CD163(F0 1.0±0.2,F1/2 2.8±0.3,F3/4 5.3±1.0,P=0.001)and MMP-9(F0 1.0±0.4,F1/2 2.8±0.3,F3/4 4.1±0.8,P=0.011)was significantly associated with increasing stage of fibrosis.CONCLUSION:Secreted macrophage products alter the phenotype and function of hepatocytes,with increased expression of inflammatory mediators,suggesting that hepatocytes actively participate in liver injury.Michelle Melino Victoria L Gadd Gene V Walker Richard Skoien Helen D Barrie Dinesh Jothimani Leigh Horsfall Alun Jones Matthew J Sweet Gethin P Thomas Andrew D Clouston Julie R Jonsson Elizabeth E Powell 2012World Journal of Gastroenterology2012,18,15:3
12Factor analysis identifies subgroups of constipation显示文摘AIM:To determine whether distinct symptom groupings exist in a constipated population and whether such grouping might correlate with quantifiable pathophysiological measures of colonic dysfunction.METHODS:One hundred and ninety-one patients presenting to a Gastroenterology clinic with constipation and 32 constipated patients responding to a newspaper advertisement completed a 53-item,wide-ranging selfreport questionnaire.One hundred of these patients had colonic transit measured scintigraphically.Factor analysis determined whether constipation-related symptoms grouped into distinct aspects of symptomatology.Cluster analysis was used to determine whether indi-vidual patients naturally group into distinct subtypes.RESULTS:Cluster analysis yielded a 4 cluster solution with the presence or absence of pain and laxative unresponsiveness providing the main descriptors.Amongst all clusters there was a considerable proportion of patients with demonstrable delayed colon transit,irritable bowel syndrome positive criteria and regular stool frequency.The majority of patients with these characteristics also reported regular laxative use.CONCLUSION:Factor analysis identified four constipation subgroups,based on severity and laxative unresponsiveness,in a constipated population.However,clear stratification into clinically identifiable groups remains imprecise.Philip G Dinning Mike Jones Linda Hunt Sergio E Fuentealba Jamshid Kalanter Denis W King David Z Lubowski Nicholas J Talley Ian J Cook 2011World Journal of Gastroenterology2011,17,11:3
