2Vitamin D deficiency in cirrhosis relates to liver dysfunction rather than aetiology显示文摘AIM: To examine the vitamin D status in patients with alcoholic cirrhosis compared to those with primary biliary cirrhosis. METHODS: Our retrospective case series comprised 89 patients with alcoholic cirrhosis and 34 patients with primary biliary cirrhosis who visited our outpatient clinic in 2005 and underwent a serum vitamin D status assessment. RESULTS: Among the patients with alcoholic cirrhosis, 85% had serum vitamin D levels below 50 nmol/L and 55% had levels below 25 nmol/L, as compared to 60% and 16% of the patients with primary biliary cirrhosis, respectively (P < 0.001). In both groups, serum vitamin D levels decreased with increasing liver disease severity, as determined by the Child-Pugh score. CONCLUSION: Vitamin D deficiency in cirrhosis relates to liver dysfunction rather than aetiology, with lower levels of vitamin D in alcoholic cirrhosis than in primary biliary cirrhosis.Mikkel Malham SΦren Peter JΦrgensen Peter Ott JΦrgen Agnholt Hendrik Vilstrup Mette Borre Jens F Dahlerup 2011World Journal of Gastroenterology2011,17,7:15
3Role of human epidermal growth factor receptor 2 in gastric cancer:Biological and pharmacological aspects显示文摘Amplification of the human epidermal growth factor receptor 2(HER2)gene and overexpression of the HER2protein is found in 15%-20%of patients with gastric and gastroesophageal junction cancer.The degree of HER2 overexpression and amplification varies with the location of the carcinoma,with higher expression in the gastroesophageal and proximal parts compared to the distal parts of the stomach.Further,HER2 overexpression and amplification also seems to be related to the Lauren histological classification,with higher levels found in the intestinal phenotype compared to the diffuse and mixed types.The prognostic properties of HER2 overexpression and amplification are still under debate,but a large number of studies seem to indicate that HER2 is a negative prognostic factor.The usefulness of HER2 targeted therapy in gastric cancer was demonstrated in the ToGA trial,where HER2-positive patients with advanced gastric and gastroesophageal junction adenocarcinoma were randomized to receive5-FU/capecitabine and cisplatin,either alone or in combination with trastuzumab.A statically significant gain in overall survival was seen in patients who received the combined treatment of trastuzumab and chemotherapy.Patients with a strong overexpression of the HER2 protein(IHC3+)specifically benefited from the treatment,with a median overall survival of 17.9 mo.As a consequence of the positive results of the ToGA trial,patients with advanced gastric or gastroesophageal junction adenocarcinoma are now routinely tested for HER2.The ToGA trial must be characterized as a landmark in the treatment of gastric cancer and it has paved the way for a number of new HER2 targeted compounds such as pertuzumab,ado-trastuzumab emtansine,lapatinib,afatinib,and dacomitinib,which are currently undergoing phaseⅡandⅢclinical testing.Overall,this review will discuss the current status of HER2 in gastric and gastroesophageal junction cancer and the future direction in relation to HER2 target therapy.Jan Tr?st J?rgensen 2014World Journal of Gastroenterology2014,20,16:11

5Chronic fatigue is associated with increased disease-related worries and concerns in inflammatory bowel disease显示文摘AIM:To investigate the impact of chronic fatigue on disease-related worries in inflammatory bowel disease (IBD) and the potential multicolinearity between subjective questionnaires.METHODS:Patients in remission or with mild-tomoderate disease activity completed the fatigue questionnaire (FQ),the rating form of IBD patient concerns (RFIPC),the Short-Form 36 (SF-36),and IBD questionnaire (N-IBDQ).In addition,clinical and epidemiological data were obtained.RESULTS:In total,140 patients were included;of which 92 were diagnosed with ulcerative colitis and 48 with Crohn's disease.The mean age of patients with chronic fatigue was 44.2 years (SD=15.8) and for non-fatigued patients was 44.7 years (SD=16.0).Chronic fatigued patients had clinically significantly increased levels of disease-related worries,as measured by Cohen's d effect size.Worries about having an ostomy bag,loss of bowel control,and energy levels were most prominent in both chronic fatigued and non-chronic fatigued IBD patients.Variance inflation factor (VIF) and tolerance indicated that there were no problematic multicolinearity among the FQ,RFIPC,SF-36 and N-IBDQ responses (VIF < 5 and tolerance > 2).CONCLUSION:Chronic fatigue is associated with increased levels of disease-related worries and concerns in IBD.Increased levels of worries were also associated with impaired health-related quality of life.Lars-Petter Jelsness-Jφrgensen Tomm Bernklev Magne Henriksen Roald Torp Bjφrn Moum 2012World Journal of Gastroenterology2012,18,5:8
6Partial external biliary diversion in bile salt export pump deficiency: Association between outcome and mutation显示文摘AIM To investigate the relation of two different mutations to the outcome of partial external biliary diversion(PEBD)in severe bile salt export pump(BSEP) deficiency.METHODS Mutations in the gene encoding BSEP leading to severe BSEP deficiency in two unrelated patients were identified by genomic sequencing. Native liver biopsies and transiently transfected human embryonic kidney(HEK) 293 cells expressing either wild-type or mutated BSEP were subjected to immunofluorescence analysis to assess BSEP transporter localization. Bile acid profiles of patient and control bile samples were generated by ultra-performance liquid chromatographytandem mass spectrometry. Wild-type and mutant BSEP transport of [~3H]-labeled taurocholate(TC) and taurochenodeoxycholate(TCDC) was assessed by vesicular transport assays.RESULTS A girl(at 2 mo) presented with pruritus, jaundice and elevated serum bile salts(BS). PEBD stabilized liver function and prevented liver transplantation. She was heterozygous for the BSEP deletion p.T919 del and the nonsense mutation p.R1235 X. At the age of 17 years relative amounts of conjugated BS in her bile were normal, while total BS were less than 3% as compared to controls. An unrelated boy(age 1.5 years) presenting with severe pruritus and elevated serum BS was heterozygous for the same nonsense and another missense mutation, p.G1032 R. PEBD failed to alleviate pruritus, eventually necessitating liver transplantation. BS concentration in bile was about 5% of controls. BS were mainly unconjugated with an unusual low amount of chenodeoxycholate derivatives(< 5%). The patients' native liver biopsies showed canalicular BSEP expression. Both BSEP p.T919 del and p.G1032 R were localized in the plasma membrane in HEK293 cells. In vitro transport assays showed drastic reduction of transport by both mutations. Using purified recombinant BSEP as quantifiable reference, per-molecule transport rates for TC and TCDC were determined to be 3 and 2 BS molecules per wild-type BSEP transporter per minute, respectively.CONCLUSION In summary, our findings suggest that residual function of BSEP as well as substrate specificity influence the therapeutic effectiveness of PEBD in progressive familial intrahepatic cholestasis type 2(PFIC-2).Philipp Ellinger Jan Stindt Carola Droge Katharina Sattler Claudia Stross Stefanie Kluge Diran Herebian Sander HJ Smits Martin Burdelski Sebastian Schulz-Jürgensen Antje Ballauff Jan Schulte am Esch Ertan Mayatepek Dieter Haussinger Ralf Kubitz Lutz Schmitt 2017World Journal of Gastroenterology2017,23,29:4

9家猪体外胰蛋白酶消化关节软骨的7.0T磁共振T2弛豫时间图与量化分析显示文摘目的应用超高场7.0T磁共振T2加权成像技术、弛豫时间图和量化分析的方法评价体外胰蛋白酶消化与未消化家猪髌骨软骨T2弛豫时间的改变。方法选择10头家猪,各取左、右侧髌骨。左侧髌骨10个为实验组,右侧髌骨10个为对照组,分别浸泡于含有胰蛋白酶的PBS溶液及PBS中,4h后取出。利用7.0T磁共振机,分别采用多回波SE序列进行扫描,获得离体家猪髌骨关节软骨的T2加权图像。用自行编制的软件重构T2弛豫时间图,人工标注感兴趣区,分层定量测定关节软骨的T2值。结果经酶诱导消化的离体家猪髌骨关节软骨T2W成像清晰,呈分层状表现,对比度好,无异常伪影。对照组与实验组关节软骨T2WI关节软骨未见局部信号异常改变。与对照组比较,实验组软骨全层、表层、中间层T2值差异有统计学意义(P<0.05),而两者的深层与钙化层差异无统计学意义(P>0.05)。结论经胰蛋白酶诱导消化可引起退变软骨T2弛豫时间改变,在软骨的表层及中间层变化明显,提示T2弛豫时间是较敏感、特异的检测指标,可进一步应用于关节软骨退变的早期诊断。周智洋 单鸿 邹学农 Steffen Ringgaard 邹立津 李海声 谢学斌 Hans StФdkilde-JФrgensen Cody Bünger 2009中国医学影像技术2009,,3:4
10Duality for cochain DG algebras显示文摘This paper develops a duality theory for connected cochain DG algebras,with particular emphasis on the non-commutative aspects.One of the main items is a dualizing DG module which induces a duality between the derived categories of DG left-modules and DG right-modules with finitely generated cohomology.As an application,it is proved that if the canonical module k=A/A≥1 has a semi-free resolution where the cohomological degree of the generators is bounded above,then the same is true for each DG module with finitely generated cohomology.JφRGENSEN Peter 2013Science China Mathematics2013,56,1:3
11Dietary supplementation of Bacillus subtilis influenced intestinal health of weaned pigs experimentally infected with a pathogenic E. coli显示文摘Background: There is growing evidence to support the beneficial effects of supplementing direct-fed microbials(DFM) on performance, health status, and immune responses of weaned pigs. Therefore, the objective of this study was to investigate dietary supplementation of Bacillus subtilis(DSM 25841) on growth performance, diarrhea, gut permeability and immunity of weaned pigs experimentally infected with a pathogenic F-18 Escherichia coli(E. coli).Results: The F18 E. coli infection reduced(P < 0.05) growth performance and intestinal villi height, whereas increased(P < 0.05) diarrhea and transcellular and paracellular permeability in the jejunum compared with non-challenged control. Supplementation of Bacillus subtilis linearly enhanced average daily gain of E. coli infected pigs from d 0 to 5 post-inoculation(PI)(P < 0.05) and d 0 to 11 PI(P = 0.058). Supplementation of high dose of Bacillus subtilis reduced(P < 0.05) both transcellular and paracellular permeability on d 5 and d11 PI compared with the E. coli infected pigs fed with control diet. E. coli infection up-regulated(P < 0.05)the m RNA expression of SLC5 A10(soluble carrier family 5 member 10) and MUC2(mucin 2) on d 5 PI, but down-regulated(P < 0.05) expression of SLC5 A10, MUC2, and CLDN1 on d 11 PI in jejunal mucosa when pigs were fed with the control diet. Supplementation of Bacillus subtilis linearly up-regulated(P < 0.05) the m RNA expression of CFTR and ZO1 on d 5 PI and SLC5 A10 and MUC2 on d 11 PI in jejunal mucosa of E. coli infected pigs. In addition, E. coli infection increased(P < 0.05) the m RNA expression of several immune genes(IL1 A, IL1 B, and IL7 on d 5 PI, and IL1 B, IL6, IL7, and TNF on d 11 PI) in the ileal mucosa of weaned pigs. Inclusion of Bacillus subtilis to control diet linearly down-regulated gene expression of IL1 A on d 5 PI(P = 0.07) and IL6 on d 11 PI(P < 0.05) in ileal mucosa of E. coli infected pigs.Conclusions: Supplementation of Bacillus subtilis(DSM 25841) enhanced growth rate and improved gut barrier function of weaned pigs experimentally infected with a pathogenic E. coli.Kwangwook Kim Yijie He Xia Xiong Amy Ehrlich Xunde Li Helen Raybould Edward R.Atwill Elizabeth A.Maga Jens JΦrgensen Yanhong Liu 2019Journal of Animal Science and Biotechnology2019,10,4:3

14Determination of basal ileal endogenous losses and standardized ileal digestibility of amino acids in barley fed to growing pigs显示文摘Background: Basal ileal endogenous amino acid(AA) losses(IAA_(end)) and standardized ileal digestibility(SID) values of cereal grains, such as barley, are apparently underestimated when determined according to the nitrogen(N)-free method. Regression analysis between the dietary apparent ileal digestible content(c AID) and total crude protein(CP) and AA can be considered as alternative approach to obtain more accurate values for IAA_(end)and SID of AA in cereal grains.Methods: Eight hulled barley genotypes were used, with barley being the only source of CP and AA in the assay diets. The diets contained 95 % as-fed of these eight barley genotypes each, ranging in CP content between 109.1 and 123.8 g/kg dry matter(DM). Nine ileally T-cannulated barrows, average body weight(BW) 30 ± 2 kg, were allotted to a row-column design comprising eight periods with 6 d each and nine pigs. On d 5 and the night of d 6 of every period, ileal digesta were collected for a total of 12 h. The IAA_(end) and the SID were determined by linear regression analysis between c AID and total dietary CP and AA.Results: There exist linear relationships between cA ID and total CP and AA(P < 0.001). The IAA_(end) of CP, Lys, Met, Thr and Trp amounted to 35.34, 1.08, 0.25, 1.02 and 0.38 g/kg DM intake(DMI), respectively, which are greater compared to average IAA_(end) determined previously under N-free feeding conditions. The SID of CP, Lys, Met, Thr and Trp was 90,79, 85, 79 and 86 %, respectively, and was greater when compared to tabulated values. Moreover, these SID values were greater than those reported in literature, based on correction of apparent ileal digestibility(AID) of CP and AA for their IAA_(end)values. Summarized, the results of the present regression analysis indicate greater IAA_(end)in barley-based diets compared to those obtained by N-free feeding.Conclusions: For low-protein feed ingredients like barley the regression method may be preferred over correction of AID values for their IAA_(end)determined under N-free feeding conditions, as intercepts and slopes of the linear regression equations between cA ID and total dietary CP and AA provide direct estimates of IAA_(end)and SID of CP and AA in the presence of the assay feed ingredient.Hanna Katharina Spindler Rainer Mosenthin Pia Rosenfelder Henry J?rgensen Knud Erik Bach Knudsen Meike Eklund 2017Journal of Animal Science and Biotechnology2017,8,1:2
15Influence of different second generation antipsychotics on the QTc interval: A pragmatic study显示文摘AIM To investigate whether differential influence on the QTc interval exists among four second generation antipsychotics(SGAs) in psychosis.METHODS Data were drawn from a pragmatic, randomized headto-head trial of the SGAs risperidone, olanzapine, quetiapine, and ziprasidone in acute admissions patients with psychosis, and with follow-up visits at discharge or maximally 6-9 wk, 3, 6, 12 and 24 mo. Electrocardiograms were recorded on all visits. To mimic clinical shared decision-making, the patients were randomized not to a single drug, but to a sequenceof the SGAs under investigation. The first drug in the sequence defined the randomization group, but the patient and/or clinician could choose an SGA later in the sequence if prior negative experiences with the first one(s) in the sequence had occurred. The study focuses on the time of, and actual use of the SGAs under investigation, that is until treatment discontinuation or change, in order to capture the direct medication effects on the QTc interval. Secondary intention-to-treat(ITT) analyses were also performed. RESULTS A total of 173 patients, with even distribution among the treatment groups, underwent ECG assessments. About 70% were males and 43% had never used antipsychotic drugs before the study. The mean antipsychotic doses in milligrams per day with standard deviations(SD) were 3.4(1.2) for risperidone, 13.9(4.6) for olanzapine, 325.9(185.8) for quetiapine, and 97.2(42.8) for ziprasidone treated groups. The time until discontinuation of the antipsychotic drug used did not differ in a statistically significant way among the groups(Log-Rank test: P = 0.171). The maximum QTc interval recorded during follow-up was 462 ms. Based on linear mixed effects analyses, the QTc interval change per day with standard error was-0.0030(0.0280) for risperidone;-0.0099(0.0108) for olanzapine;-0.0027(0.0170) for quetiapine, and-0.0081(0.0229) for ziprasidone. There were no statistically significant differences among the groups in this regard. LME analyses based on ITT groups(the randomization groups), revealed almost identical slopes with-0.0063(0.0160) for risperidone,-0.0130(0.0126) for olanzapine,-0.0034(0.0168) for quetiapine, and-0.0045(0.0225) for ziprasidone. CONCLUSION None of the SGAs under investigation led to statistically significant QTc prolongation. No statistically significant differences among the SGAs were found.Roy E Olsen Rune A Kroken Sigmund Bj?rhovde Kristina Aanesen Hugo A J?rgensen Else-Marie L?berg Erik Johnsen 2016World Journal of Psychiatry2016,6,4:2
