| 1 | Nonalcoholic fatty liver disease: An overview of current insights in pathogenesis, diagnosis and treatment显示文摘Estimates of people suffering from overweight (one billion) and obesity (300 million) are increasing. The accumulation of triglycerides in the liver, in the absence of excess alcohol intake, has been described in the early sixties. It was not until 1980, however, that Ludwig et al named this condition nonalcoholic steatohepatitis (NASH). Subsequently, nonalcoholic fatty liver disease (NAFLD) has been used as a general name for conditions ranging from simple steatosis through steatohepatitis to end-stage liver disease (cirrhosis). Many studies have demonstrated the significant correlation with obesity and insulin resistance. Other studies have revealed a signifi- cant correlation between hepatic steatosis, cardiovascu- lar disease and increased intima-media thickness. WHO estimated that at least two million patients will develop cirrhosis due to hepatic steatosis in the years to come. Longitudinal cohort studies have demonstrated that those patients with cirrhosis have a similar risk to devel- op hepatocellular carcinoma as those with other causes of cirrhosis. Taken all together, NAFLD has become the third most important indication for liver transplantation. There- fore, training programmes in internal medicine, gastroen- terology and hepatology should stress the importance of diagnosing this entity and treat properly those at risk for developing complications of portal hypertension and con- comittant cardiovascular disease. This review will focus on the clinical characteristics, pathophysiology, imaging tech- niques and the readily available therapeutic options. | Tim CMA Schreuder Bart J Verwer Carin MJ van Nieuwkerk Chris JJ Mulder | 2008 | World Journal of Gastroenterology2008，14，16： | 35 |
| 2 | 模拟氮沉降对克氏针茅草原土壤有机碳的短期影响显示文摘为更好地了解天然草地土壤有机碳对氮沉降增加的响应,2011年在内蒙古太仆寺旗的克氏针茅(Stipa krylovii)草原上开展了模拟氮沉降的控制实验,设置对照(CK)和5个模拟氮沉降(NO-3)处理,分别为2(N1)、5(N2)、10(N3)、25(N4)和50 g N m-2a-1(N5)。生长季末,采集每个样地中0—2 cm和2—10 cm深度土壤进行有机碳含量及组成的分析,并进行实验室矿化培养。结果表明,土壤颗粒态有机碳(POC)对氮添加响应敏感,N1和N2处理下的POC含量高于CK,N3、N4和N5处理则低于CK。5个模拟氮沉降处理下的矿质结合态有机碳(MOC)含量均高于对照,但差别不显著。不同氮沉降水平下0—2 cm土层的碳矿化潜势为N2>N1>N4>N3>CK>N5,且N1,N2,N3和N4处理均显著高于CK和N5;2—10 cm土层的碳矿化潜势为N2>N1>N3>CK>N4>N5,N1、N2和N3显著高于CK、N4及N5。不同施氮处理对群落净第一性生产力有明显影响,N5的净第一性生产力和地上生物量显著低于对照和其它施氮处理,N1的0—10 cm地下生物量显著高于对照和其它处理,N5的凋落物量显著高于对照。模拟氮沉降短期内对土壤总有机碳(SOC)含量无显著影响。 | 祁瑜 Mulder J 段雷 黄永梅 | 2015 | 生态学报2015，35，4： | 23 |
| 3 | Efficacy of thioguanine treatment in inflammatory bowel disease: A systematic review显示文摘AIM To critically assess the available literature regarding the efficacy of thioguanine treatment in inflammatory bowel disease(IBD) patients, irrespective of the(hepato-) toxicity profile.METHODS A systematic literature search of the MEDLINE database using Pub Med was performed using the keywords 'thioguanine', '6-TG', 'thioguanine', 'inflammatory bowel disease', 'IBD', 'Crohn's disease', 'Ulcerative colitis' and 'effectiveness' in order to identify relevant articles published in English starting from 2000. Reference lists of the included articles were crosschecked for missing articles. Reviewed manuscripts concerning the effectiveness of thioguanine treatment in IBD were reviewed by the authors and the data were extracted. Data were subsequently analyzed with descriptive statistics. Due to the lack of standardized outcomes, a formal meta-analysis was not performed.RESULTS A total of 11 applicable studies were found that involved the effectiveness of thioguanine therapy in IBD. Eight studies were conducted in a prospectivemanner, in the remaining three studies, data was collected retrospectively. In total, 353 IBD-patients(225 patients with Crohn's disease, 119 with ulcerative colitis and nine with unclassified IBD) with prior azathioprine/mercaptopurine resistance and/or intolerance(n = 321) or de novo thioguanine administration(n = 32) were included for analysis, of which 228(65%) had clinical improvement on thioguanine therapy, based on standard IBD questionnaires, biochemical parameters or global physician assessments. Short-term results were based on 268 treatment years(median follow-up 9 mo, range 3-22 mo) with a median daily dose of 20 mg(range 10-80 mg). Discontinuation, mostly due to adverse events, was reported in 72 patients(20%). CONCLUSION The efficacy of thioguanine therapy in IBD patients intolerant to conventional thiopurine therapy is observed in 65%, with short term adverse events in 20% of patients. | Berrie Meijer Chris JJ Mulder Godefridus J Peters Adriaan A van Bodegraven Nanne KH de Boer | 2016 | World Journal of Gastroenterology2016，22，40： | 5 |
| 4 | On tolerability and safety of a maintenance treatment with 6-thioguanine in azathioprineor 6-mercaptopurine intolerant IBD patients显示文摘AIM: To determine the tolerability and safety profile of a low-dose maintenance therapy with 6-TG in azathioprine (AZA) or 6-mercaptopurine (6-MP) intolerant inflammatory bowel disease (IBD) patients over a treatment period of at least 1 year.METHODS: Database analysis.RESULTS: Twenty out of ninety-five (21%) patients discontinued 6-TG (mean dose 24.6 mg; mean 6-TGN level 540 pmol/8×108 RBC) within 1 year. Reasons for discontinuation were GI complaints (31%), malaise (15%)and hepatotoxicity (15%). Hematological events occurred in three patients, one discontinued treatment. In the 6-TG-tolerant group, 9% (7/75) could be classified as hepatotoxicity. An abdominal ultrasound was performed in 54% of patients, one patient had splenomegaly.CONCLUSION: The majority of AZA or 6-MP-intolerant IBD patients (79%) is able to tolerate maintenance treatment with 6-TG (dosages between 0.3 and 0.4 mg/kg per d). 6-TG may still be considered as an escape maintenance immunosuppressant in this difficult to treat group of patients, taking into account potential toxicity and efficacy of other alternatives. The recently reported hepatotoxicity is worrisome and 6-TG should therefore be administered only in prospective trials. | Nanne KH de Boer Luc JJ Derijks Lennard PL Gilissen Daniel W Hommes Leopold GJB Engels Sybrand Y de Boer Gijsbertus den Hartog Piet M Hooymans Anja BU M(?)kelburg Barend D Westerveld Anton HJ Naber Chris JJ Mulder Dirk J de Jong | 2005 | World Journal of Gastroenterology2005，11，35： | 4 |
| 5 | Are faecal markers good indicators of mucosal healing in inflammatory bowel disease?显示文摘AIM: To review the published literature concerning the accuracy of faecal inflammatory markers for identifying mucosal healing. METHODS: Bibliographical searches were performed in MEDLINE electronic database up to February 2015,using the following terms: 'inflammatory bowel disease','Crohn′s disease','ulcerative colitis','faecal markers','calprotectin','lactoferrin','S100A12','endoscop*','mucosal healing','remission'. In addition,relevant references from these studies were also included. Data were extracted from the published papers including odds ratios with 95%CI,P values and correlation coefficients. Data were grouped together according to each faecal marker,Crohn's disease or ulcerative colitis,and paediatric compared with adult study populations. Studies included in this review assessed mucosal inflammation by endoscopic and/or histological means and compared these findings to faecal marker concentrations in inflammatory bowel diseases(IBD) patient cohorts. Articles had to be published between 1990 and February 2015 and written in English. Papers excluded from the review were those where the faecal biomarker concentration was compared between patients with IBD and controls or other disease groups,those where serum biomarkers were used,those with a heterogeneous study population and those only assessing post-operative disease. RESULTS: The available studies show that faecal markers,such as calprotectin and lactoferrin,are promising non-invasive indicators of mucosal healing. However,due to wide variability in study design,especially with regard to the definition of mucosal healing and evaluation of marker cut offs,the available data do not yet indicate the optimal roles of these markers. Thirty-six studies published between 1990 and 2014 were included. Studies comprised variable numbers of study participants,considered CD(15-164 participants) or UC(12-152 participants) separately or as a combined group(11-252 participants). Eight reports included paediatric patients. Several indices were used to document mucosal inflammation,encompassing elevenendoscopic and eight histologic grading systems. The majority of the available reports focused on faecal calprotectin(33 studies),whilst others assessed faecal lactoferrin(13 studies) and one study assessed S100A12. Across all of the biomarkers,there is a wide range of correlation describing the association between faecal markers and endoscopic disease activity(r values ranging from 0.32 to 0.87,P values ranging from < 0.0001 to 0.7815). Correlation coefficients are described in almost all studies and are used more commonly than outcome measures such as sensitivity,specificity,PPV and/or NPV. Overall,the studies that have evaluated faecal calprotectin and/or faecal lactoferrin and their relationship with endoscopic disease activity show inconsistent results. CONCLUSION: Future studies should report the results of faecal inflammatory markers in the context of mucosal healing with clear validated cut offs. | Gudula JAM Boon Andrew S Day Chris J Mulder Richard B Gearry | 2015 | World Journal of Gastroenterology2015，21，40： | 4 |
| 6 | Retrospective analysis of old-age colitis in the Dutch inflammatory bowel disease population显示文摘AIM: To describe the characteristics of Dutch patients with chronic inflammatory bowel disease (IBD) first diagnosed above 60 years of age-a disease also known as old-age colitis (OAC) and to highlight a condition that has a similar appearance to IBD, namely segmen- tal colitis associated with diverticular disease (SCAD). METHODS: A retrospective longitudinal survey of patient demographic and clinical characteristics, disease characteristics, diagnostic methods, management and course of disease was performed. The median follow-up period was 10 years. RESULTS: Of a total of 1100 IBD patients attending the Department of Gastroenterology, 59 (5%) [median age 82 years (range 64-101); 25 male (42%)] were identified. These patients were diagnosed with ulcerative colitis (n = 37, 61%), Crohn’s disease (n = 14, 24%), and indeterminate colitis (n = 8, 15%). Remission was induced in 40 (68%) patients within a median interval of 6 mo (range 1-21) and immunosuppressive therapy was well tolerated. Histological evaluation based on many biopsy samples and the course of the disease led to other diagnosis, namely SCAD instead of IBD in five (8%) patients. CONCLUSION: OAC is not an infrequent problem for the gastroenterologist, and should be considered in the evaluation of older patients with clinical featuressuggestive of IBD. Extra awareness and extensive biopsy sampling are required in order to avoid an erroneous diagnosis purely based on histological mimicry of changes seen in SCAD, when diagnosing IBD in the presence of diverticulosis coli. | Muhammed Hadithi Marcel Cazemier Gerrit A Meijer Elisabeth Bloemena Richel J Felt-Bersma Chris J Mulder Stephan GM Meuwissen Amado Salvador Pea Adriaan A van Bodegraven | 2008 | World Journal of Gastroenterology2008，14，20： | 3 |
| 7 | Effect of B vitamin supplementation on plasma homocysteine levels in celiac disease显示文摘AIM: To investigate the effect of vitamin supplements on homocysteine levels in patients with celiac disease. METHODS: Vitamin B6, folate, vitamin B12, and fasting plasma homocysteine levels were measured in 51 consecutive adults with celiac disease [median (range) age 56 (18-63) years; 40% men, 26 (51%) had villous atrophy, and 25 (49%) used B-vitamin supplements] and 50 healthy control individuals matched for age and sex. Finally, the C677T polymorphism of 5,10-methylene tetrahydrofolate reductase (MTHFR) was evaluated in 46 patients with celiac disease and all control individuals. RESULTS: Patients with celiac disease and using vitamin supplements had higher serum vitamin B6 (P = 0.003),folate (P < 0.001), and vitamin B12 (P = 0.012) levels than patients who did not or healthy controls (P = 0.035, P < 0.001, P = 0.007, for vitamin B6, folate, and vitamin B12, respectively). Lower plasma homocysteine levels were found in patients using vitamin supplements than in patients who did not (P = 0.001) or healthy controls (P = 0.003). However, vitamin B6 and folate, not vitamin B12, were significantly and independently associated with homocysteine levels. Twenty-four (48%) of 50 controls and 23 (50%) of 46 patients with celiac disease carried the MTHFR thermolabile variant T-allele (P = 0.89). CONCLUSION: Homocysteine levels are dependent on Marsh classification and the regular use of B-vitamin supplements is effective in reduction of homocysteine levels in patients with celiac disease and should be considered in disease management. | Muhammed Hadithi Chris JJ Mulder Frank Stam Joshan Azizi J Bart A Crusius Amado Salvador Pea Coen DA Stehouwer Yvo M Smulders | 2009 | World Journal of Gastroenterology2009，15，8： | 3 |
