1最新AD研究用诊断标准:IWG-2标准显示文摘在过去的8年中,国际工作组织(IWG)和美国国立老化研究院-阿尔茨海默协会(NIA-AA)建立了阿尔茨海默病(AD)诊断标准,它能更好地定义AD的临床表型,整合了生物标记物于诊断流程中,并覆盖了疾病的全程。本意见书充分地权衡了IWG标准的优缺点,建议改进诊断框架。依据这些改进,AD的诊断变得简单,只要有恰当的AD临床表型(典型或不典型)和与AD的病理相一致的病理生理学生物标志物出现。我们认为疾病的下游的定位性生物标志,如容积性磁共振成像(MRI)和氟脱氧葡萄糖-正电子发射型计算机断层成像(FDG-PET)等,适合更好地测量和监测疾病过程。本文还详述了非典型性AD、混合性AD和AD临床前期的特异诊断标准。陈刚 曹雯炜 俞羚 糜建华 Dubois B Feldman HH Jacova C Hampel H Molinuevo JL Blennow K DeK osky ST Gauthier S Selkoe D Bateman R Cappa S Crutch S Engelborghs S Frisoni GB Fox NC Galasko D Habert MO Jicha GA Nordberg A Pasquier F Rabinovici G Robert P Rowe C Salloway S Sarazin M Epelbaum S de Souza LC Vellas B Visser PJ Schneider L Stern Y Scheltens P Cummings JL 2014神经病学与神经康复学杂志2014,11,3:31
2Role of the gut microbiota in inflammatory bowel disease pathogenesis: What have we learnt in the past 10 years?显示文摘Our understanding of the microbial involvement in inflammatory bowel disease(IBD) pathogenesis has increased exponentially over the past decade. The development of newer molecular tools for the global assessment of the gut microbiome and the identification of nucleotide-binding oligomerization domain-containing protein 2 in 2001 and other susceptibility genes for Crohn's disease in particular has led to better understanding of the aetiopathogenesis of IBD. The microbial studies have elaborated the normal composition of the gut microbiome and its perturbations in the setting of IBD. This altered microbiome or 'dysbiosis' is a key player in the protracted course of inflammation in IBD. Numerous genome-wide association studies have identified further genes involved in gastrointestinal innate immunity(including polymorphisms in genes involved in autophagy: ATG16L1 and IGRM), which have helped elucidate the relationship of the local innate immunity with the adjacent luminal bacteria. These developments have also spurred the search for specific pathogens which may have a role in the metamorphosis of the gut microbiome from a symbiotic entity to a putative pathogenic one. Here we review advances in our understanding of microbial involvement in IBD pathogenesis over the past 10 years and offer insight into how this will shape our therapeutic management of the disease in the coming years.Georgina L Hold Megan Smith Charlie Grange Euan Robert Watt Emad M El-Omar Indrani Mukhopadhya 2014World Journal of Gastroenterology2014,20,5:21
3Radioembolization 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 2008World Journal of Gastroenterology2008,14,11:14
4High-throughput screening of mouse gene knockouts identifies established and novel skeletal phenotypes显示文摘Screening gene function in vivo is a powerful approach to discover novel drug targets. We present high-throughput screening(HTS) data for 3 762 distinct global gene knockout(KO) mouse lines with viable adult homozygous mice generated using either gene-trap or homologous recombination technologies. Bone mass was determined from DEXA scans of male and female mice at 14 weeks of age and by microCT analyses of bones from male mice at 16 weeks of age. Wild-type(WT) cagemates/littermates were examined for each gene KO. Lethality was observed in an additional 850 KO lines. Since primary HTS are susceptible to false positive findings, additional cohorts of mice from KO lines with intriguing HTS bone data were examined. Aging,ovariectomy, histomorphometry and bone strength studies were performed and possible non-skeletal phenotypes were explored. Together, these screens identified multiple genes affecting bone mass: 23 previously reported genes(Calcr, Cebpb, Crtap, Dcstamp, Dkk1, Duoxa2, Enpp1, Fgf23, Kiss1/Kiss1 r, Kl(Klotho),Lrp5, Mstn, Neo1, Npr2, Ostm1, Postn, Sfrp4, Slc30a5, Slc39a13, Sost, Sumf1, Src, Wnt10b), five novel genes extensively characterized(Cldn18, Fam20 c, Lrrk1, Sgpl1, Wnt16), five novel genes with preliminary characterization(Agpat2, Rassf5, Slc10a7, Slc26a7, Slc30a10) and three novel undisclosed genes coding for potential osteoporosis drug targets.Robert Brommage Jeff Liu Gwenn M Hansen Laura L Kirkpatrick David G Potter Arthur T Ss Brian Zambrowicz David R Powell Peter Vogel 2014Bone Research2014,2,3:7
5Dementia and osteoporosis in a geriatric population: Is there a common link?显示文摘AIM To determine the existence of a common pathological link between dementia and osteoporosis through reviewing the current evidence base. METHODS This paper reviews the current literature on osteoporosis and dementia in order to ascertain evidence of a common predisposing aetiology. A literature search of Ovid MEDLINE(1950 to June 2016) was conducted. The keywords 'osteoporosis', 'osteoporotic fracture', 'dementia' and 'Alzheimer's disease'(AD) were used to determine the theoretical links with the most significant evidence base behind them. The key links were found to be vitamins D and K, calcium, thyroid disease, statins, alcohol and sex steroids. These subjects were then searched in combination with the previous terms and the resulting papers manually examined. Theoretical, in vitro and in vivo research were all used to inform this review which focuses on the most well developed theoretical common causes for dementia(predominantly Alzheimer's type) and osteoporosis.RESULTS Dementia and osteoporosis are multifaceted disease processes with similar epidemiology and a marked increase in prevalence in elderly populations. The existence of a common link between the two has been suggested despite a lack of clear pathological overlap in our current understanding. Research to date has tended to be fragmented and relatively weak in nature with multiple confounding factors reflecting the difficulties of in vivo experimentation in the population of interest. Despite exploration of various possible mechanisms in search for a link between the two pathologies, this paper found that it is possible that these associations are coincidental due to the nature of the evidence available. One finding in this review is that prior investigation into common aetiologies has found raised amyloid beta peptide levels in osteoporotic bone tissue, with a hypothesis that amyloid beta disorders are systemic disorders resulting in differing tissue manifestations. However, our findings were that the most compelling evidence of a common yet independent aetiology lies in the APOE4 allele, which is a well-established risk for AD but also carries an independent association with fracture risk. The mechanism behind this is thought to be the reduced plasma vitamin K levels in individuals exhibiting the APOE4 allele which may be amplified by the nutritional deficiencies associated with dementia, which are known to include vitamins K and D. The vitamin theory postulates that malnutrition and reduced exposure to sunlight in patients with AD leads to vitamin deficiencies. CONCLUSION Robust evidence remains to be produced regarding potential links and regarding the exact aetiology of these diseases and remains relevant given the burden of dementia and osteoporosis in our ageing population. Future research into amyloid beta, APOE4 and vitamins K and D as the most promising aetiological links should be welcomed.Candice L Downey Adam Young Emily F Burton Simon M Graham Robert J Macfarlane Eva-Maria Tsapakis Eleftherios Tsiridis 2017World Journal of Orthopedics2017,8,5:6
6Recent trends in liver transplantation for alcoholic liver disease in the United States显示文摘AIM To examine temporal changes in the indications for liver transplantation(LT) and characteristics of patients transplanted for alcoholic liver disease(ALD).METHODS We performed a retrospective cohort analysis of trends in the indication for LT using the United Network for Organ Sharing(UNOS) database between 2002 and 2015. Patients were grouped by etiology of the liver disease and characteristics were compared using χ~2 and t-tests. Time series analysis was used identifying any year with a significant change in the number of transplants per year for ALD, and before and after eras were modeled using a general linear model. Subgroup analysis of recipients with ALD was performed by age group, gender, UNOS region and etiology(alcoholic cirrhosis, alcoholic hepatitis and hepatitis C-alcoholic cirrhosis dual listing).RESULTS Of 74216 liver transplant recipients, ALD(n = 9400, 12.7%) was the third leading indication for transplant after hepatitis C and hepatocellular carcinoma. Transplants for ALD, increased from 12.8%(553) in 2002 to 16.5%(1020) in 2015. Time series analysis indicated a significant increase in the number of transplants per year for ALD in 2013(P = 0.03). There were a stable number of transplants per year between 2002 and 2012(linear coefficient 3, 95%CI:-4.6, 11.2) an increase of 177 per year between 2013 and 2015(95%CI: 119, 234). This increase was significant for all age groups except those 71-83 years old, was observed for both genders, and was incompletely explained by a decrease in transplants for hepatitis C and ALD dual listing. All UNOS regions except region 9 saw an increase in the mean number of transplants per year when comparing eras, and this increase was significant in regions 2, 3, 4, 5, 6, 8, 10 and 11.CONCLUSION There has been a dramatic increase in the number of transplants for ALD starting in 2013.Catherine E Kling James D Perkins Robert L Carithers Dennis M Donovan Lena Sibulesky 2017World Journal of Hepatology2017,9,36:6
7Colonic manifestations of PTEN hamartoma tumor syndrome: Case series and systematic review显示文摘AIM:To investigate our clinical experience with the colonic manifestations of phosphatase and tensin homolog on chromosome ten(PTEN)hamartoma tumor syndrome(PHTS)and to perform a systematic literature review regarding the same.METHODS:This study was approved by the appropriate institutional review board prior to initiation.A clinical genetics database was searched for patients with PHTS or a component syndrome that received gastrointestinal endoscopy or pathology interpretation at our center.These patient’s records were retrospectively reviewed for clinical characteristics(including family history and genetic testing),endoscopy results and pathology findings.We also performed a systematic review of the literature for case series of PHTS or component syndromes that reported gastrointestinal manifestations and investigations published after consensus diagnostic criteria were established in 1996.These results were compiled and reported.RESULTS:Eight patients from our institution met initial inclusion criteria.Of these,5 patients underwent4.2 colonoscopies at mean age 45.8±10.8 years.All were found to have colon polyps during their clinical course and polyp histology included adenoma,hyperplastic,ganglioneuroma and juvenile.No malignant lesions were identified.Two had multiple histologic types.One patient underwent colectomy due to innumerable polyps and concern for future malignant potential.Systematic literature review of PHTS patients undergoing endoscopy revealed 107 patients receiving colonoscopy at mean age 37.4 years.Colon polyps were noted in92.5%and multiple colon polyp histologies were reported in 53.6%.Common polyp histologies included hyperplastic(43.6%),adenoma(40.4%),hamartoma(38.3%),ganglioneuroma(33%)and inflammatory(24.5%)polyps.Twelve(11.2%)patients had colorectal cancer at mean age 46.7 years(range 35-62).Clinical outcomes secondary to colon polyposis and malignancy were not commonly reported.CONCLUSION:PHTS has a high prevalence of colon polyposis with multiple histologic types.It should be considered a mixed polyposis syndrome.Systematic review found an increased prevalence of colorectal cancer and we recommend initiating colonoscopy for colorectal cancer surveillance at age 35 years.Peter P Stanich Robert Pilarski Jonathan Rock Wendy L Frankel Samer El-Dika Marty M Meyer 2014World Journal of Gastroenterology2014,20,7:5
8Mental and physical symptoms associated with lower social support for patients with hepatitis C显示文摘AIM: To systematically examine the impact of the hepatitis C virus (HCV) diagnosis on patients' level of social support in a large-scale study. METHODS: Patients evaluated and treated for HCV in a tertiary referral center were enrolled in a cross-sectional study. Demographic data, functional and emotional status as measured by the Hospital Anxiety and Depression Scale (HAD) and the Sickness Impact Profile (SIP), severity of liver disease, mode of acquisition, and physical and psychiatric comorbidities were collected from patients or abstracted from the medical record. All participants completed a semi-structured interview, addressing questions of social support. RESULTS: A total of 342 patients (mean age 45.2 years; 37% women) were enrolled. Ninety-two (27%) patients described lower levels of support by family and friends. Nearly half of the participants (45%) noted the loss of at least one relationship due to the disease. Fears related to transmitting the disease (25%) were common and often associated with ignorance or even discrimination by others (19%). Nearly one fifth of the patients did not share information about their disease with others to avoid being stigmatized. Lower levels of social support were significantly associated with living alone, being unemployed, being excluded from antiviral therapy, having psychiatric comorbidities, contracting HCV through intravenous drug use, having high levels of anxiety and depression as measured by the HAD and negative mood state as measured by the SIP. Patients reporting lower levels of social support also noted more physical symptoms as measured by the SIP. CONCLUSION: Patients with hepatitis C often face significant social problems, ranging from social isolation to familial stress. The most common concerns reflect a limited insight of patients and their relatives and friends about the disease, the risk factors for its spread, and about potential consequences. Our data suggest that educational interventions targeting support persons and the stressors identified in our findings may lessen or alleviate the social strains patients with hepatitis C experience.Julie A Blasiole Laura Shinkunas Douglas R LaBrecque Robert M Arnold Susan L Zickmund 2006World Journal of Gastroenterology2006,12,29:5
9Open label trial of granulocyte apheresis suggests therapeutic efficacy in chronically active steroid refractory ulcerative colitis显示文摘AIM:To study the efficacy, safety, and feasibility of a granulocyte adsorptive type apheresis system for the treatment of patients with chronically active ulcerative colitis despite standard therapy.METHODS: An open label multicenter study was carried out in 39 patients with active ulcerative colitis (CAI6-8) despite continuous use of steroids (a minimum total dose of 400 mg prednisone within the last 4 wk).Patients received a total of five aphereses using a granulocyte adsorptive technique (Adacolumn(R), Otsuka Pharmaceutical Europe, UK). Assessments at wk 6 and during follow-up until 4 mo comprised clinical (CAI) and endoscopic (EI) activity index, histology, quality of life(IBDQ), and laboratory tests.RESULTS: Thirty-five out of thirty-nine patients were qualified for intent-to-treat analysis. After the apheresis treatment at wk 6, 13/35 (37.1%) patients achieved clinical remission and 10/35 (28.6%) patients had endoscopic remission (CAI<4, EI<4). Quality of life (IBDQ) increased significantly (24 points, P<0.01)at wk 6. Apheresis could be performed in all but one patient. Aphereses were well tolerated, only one patient experienced anemia.CONCLUSION: In patients with steroid refractory ulcerative colitis, five aphereses with a granulocyte/monocyte depleting filter show potential short-term efficacy. Tolerability and technical feasibility of the procedure are excellent.Wolfgang Kruis Axel Dignass Elisabeth Steinhagen-Thiessen Julia Morgenstern Joachim M(o|¨)ssner Stephan Schreiber Maurizio Vecchi Alberto Malesci Max Reinshagen Robert L(o|¨)fberg 2005World Journal of Gastroenterology2005,11,44:4
10Use of the Endocuff during routine colonoscopy examination improves adenoma detection: A meta-analysis显示文摘AIM To perform meta-analysis of the use of Endocuff during average risk screening colonoscopy.METHODS Scopus, Cochrane databases, MEDLINE/Pub Med, and CINAHL were searched in April 2016. Abstracts from Digestive Disease Week, United European Gastroenterology, and the American College of Gastroenterology meeting were also searched from 2004-2015. Studies comparing EC-assisted colonoscopy(EAC) to standard colonoscopy, for any indication, were included in the analysis. The analysis was conducted by using the Mantel-Haenszel or DerS imonian and Laird models with the odds ratio(OR) to assess adenoma detection, cecal intubation rate, and complications performed. RESULTS Nine studies(n = 5624 patients) were included in the analysis. Compared to standard colonoscopy, procedures performed with EC had higher frequencies for adenoma(OR = 1.49, 95%CI: 1.23-1.80; P = 0.03), and sessile serrated adenomas detection(OR = 2.34 95%CI: 1.63-3.36; P < 0.001). There was no significant difference in cecal intubation rates between the EACgroup and standard colonoscopy(OR = 1.26, 95%CI: 0.70-2.27, I2 = 0%; P = 0.44). EAC was associated with a higher risk of complications, most commonly being superficial mucosal injury without higher frequency for perforation.CONCLUSION The use of an EC on colonoscopy appears to improve pre-cancerous polyp detection without any difference in cecal intubation rates compared to standard colonoscopy.Matthew Chin William Karnes M Mazen Jamal John G Lee Robert Lee Jason Samarasena Matthew L Bechtold Douglas L Nguyen 2016World Journal of Gastroenterology2016,22,43:4
11Outcomes and patients' perspectives of transition from paediatric to adult care in inflammatory bowel disease显示文摘AIM: To describe the disease and psychosocialoutcomes of an inflammatory bowel disease(IBD) transition cohort and their perspectives.METHODS: Patients with IBD, aged > 18 years, who had moved from paediatric to adult care within 10 years were identified through IBD databases at three tertiary hospitals. Participants were surveyed regarding demographic and disease specific data and their perspectives on the transition process. Survey response data were compared to contemporaneously recorded information in paediatric service case notes. Data were compared to a similar age cohort who had never received paediatric IBD care and therefore who had not undergone a transition process. RESULTS: There were 81 returned surveys from 46 transition and 35 non-transition patients. No statistically significant differences were found in disease burden, disease outcomes or adult roles and responsibilities between cohorts. Despite a high prevalence of mood disturbance(35%), there was a very low usage(5%) of psychological services in both cohorts. In the transition cohort, knowledge of their transition plan was reported by only 25/46 patients and the majority(54%) felt they were not strongly prepared. A high rate(78%) of discussion about work/study plans was recorded prior to transition, but a near complete absence of discussion regarding sex(8%), and other adult issues was recorded. Both cohorts agreed that their preferred method of future transition practices(of the options offered) was a shared clinic appointment with all key stakeholders. CONCLUSION: Transition did not appear to adversely affect disease or psychosocial outcomes. Current transition care processes could be optimised, with better psychosocial preparation and agreed transition plans.Alice L Bennett David Moore Peter A Bampton Robert V Bryant Jane M Andrews 2016World Journal of Gastroenterology2016,22,8:3

13Anal intraepithelial neoplasia: A review of diagnosis and management显示文摘Anal intraepithelial neoplasia(AIN) is a premalignant lesion of the anal mucosa that is a precursor to anal cancer. Although anal cancer is relatively uncommon, rates of this malignancy are steadily rising in the United States, and among certain high risk populations the incidence of anal cancer may exceed that of colon cancer. Risk factors for AIN and anal cancer consist of clinical factors and behaviors that are associated with the acquisition and persistence of human papilloma virus(HPV) infection. The strongest HPV-associated risk factors are HIV infection, receptive anal intercourse, and high risk sexual behavior. A history of HPVmediated genital cancer, which suggests infection with an oncogenic HPV strain, is another risk factor for AIN/anal cancer. Because progression of AIN to anal cancer is known to occur in some individuals over several years, screening for AIN and early anal cancer, as well as treatment of advanced AIN lesions, is reasonable in certain high-risk populations. Although randomized controlled trials evaluating screening and treatment outcomes are lacking, experts support routine screening for AIN in high risk populations. Screening is performed using anal cytological exams, similar to those performed in cervical cancer screening programs, along with direct tissue evaluation and biopsy via high resolution anoscopy. AIN can be treated using topical therapies such as imiquimod, 5-flurouracil, and trichloroacetic acid, as well as ablative therapies such as electrocautery and laser therapy. Reductions in AIN and anal cancer rates have been shown in studies where high-risk populations were vaccinated against the oncogenic strains of HPV. Currently, the CDC recommends both high-risk and average-risk populations be vaccinated against HPV infection using the quadrivalent or nonavalent vaccines. It is important for clinicians to be familiar with AIN and the role of HPV vaccination, particularly in high risk populations.Joseph R Roberts Lacey L Siekas Andrew M Kaz 2017World Journal of Gastrointestinal Oncology2017,9,2:3
14A framework infrageneric classification of Carex (Cyperaceae) and its organizing principles显示文摘Phylogenetic studies of Carex L.(Cyperaceae)have consistently demonstrated that most subgenera and sections are para-or polyphyletic.Yet,taxonomists continue to use subgenera and sections in Carex classification.Why?The Global Carex Group(GCG)here takes the position that the historical and continued use of subgenera and sections serves to(i)organize our understanding of lineages in Carex,(ii)create an identification mechanism to break the~2000 species of Carex into manageable groups and stimulate its study,and(iii)provide a framework to recognize morphologically diagnosable lineages within Carex.Unfortunately,the current understanding of phylogenetic relationships in Carex is not yet sufficient for a global reclassification of the genus within a Linnean infrageneric(sectional)framework.Rather than leaving Carex classification in its current state,which is misleading and confusing,we here take the intermediate steps of implementing the recently revised subgeneric classification and using a combination of informally named clades and formally named sections to reflect the current state of our knowledge.This hybrid classification framework is presented in an order corresponding to a linear arrangement of the clades on a ladderized phylogeny,largely based on the recent phylogenies published by the GCG.It organizes Carex into six subgenera,which are,in turn,subdivided into 62 formally named Linnean sections plus 49 informal groups.This framework will serve as a roadmap for research on Carex phylogeny,enabling further development of a complete reclassification by presenting relevant morphological and geographical information on clades where possible and standardizing the use of formal sectional names.Eric H.Roalson Pedro Jiménez-Mejías Andrew L.Hipp Carmen Benítez-Benítez Leo P.Bruederle Kyong-Sook Chung Marcial Escudero Bruce A.Ford Kerry Ford Sebastian Gebauer Berit Gehrke Marlene Hahn Muhammad Qasim Hayat Mathias H.Hoffmann Xiao-Feng Jin Sangtae Kim Isabel Larridon Étienne Léveillé-Bourret Yi-Fei Lu Modesto Luceño Enrique Maguilla Jose IgnacioMárquez-Corro Santiago Martín-Bravo Tomomi Masaki Mónica Míguez Robert F.C.Naczi Anton A.Reznicek Daniel Spalink Julian R.Starr Uzma Tamara Villaverde Marcia J.Waterway Karen L.Wilson and Shu-Ren Zhang 2021Journal of Systematics and Evolution2021,59,4:3
15Metastatic recurrence to a solitary lymph node four years after hepatic lobectomy for primary hepatocellular carcinoma显示文摘This report describes a patient that developed recurrent metastatic hepatocellular carcinoma(HCC) to a suprapancreatic lymph node four years after being treated for primary HCC via complete left hepatectomy. Metastatic HCC was proven by pathologic confirmation. The report addresses the role of surgical resection as a treatment modality for recurrent HCC to solitary lymph nodes. The role of biological chemotherapy as adjuvant treatment is also addressed.Michael L Caparelli Nathan J Roberts Timothy S Braverman Robert M Stevens Edward R Broun Shyam Allamaneni 2016World Journal of Hepatology2016,8,23:2

17NOD2 and ATG16L1 polymorphisms affect monocyte responses in Crohn's disease显示文摘AIM:To assess whether polymorphisms in NOD2 and ATG16L1 affect cytokine responses and mycobacterium avium subspecies paratuberculosis (MAP) survival in monocytes from Crohn's disease (CD) patients.METHODS:Monocytes were isolated from peripheral blood of CD patients of known genotype for common single nucleotide polymorphisms of NOD2 and ATG16L1.Monocytes were challenged with MAP and bacterial persistence assessed at subsequent time-points.Cytokine responses were assayed using a Milliplex multi-analyte profiling assay for 13 cytokines.RESULTS:Monocytes heterozygous for a NOD2 polymorphism (R702W,P268S,or 1007fs) were more permissive for growth of MAP (P=0.045) than those without.There was no effect of NOD2 genotype on subsequent cytokine expression.The T300A polymorphism ofATG16L1 did not affect growth of MAP in our model (P=0.175),but did increase expression of cytokines interleukin (IL)-10 (P=0.047) and IL-6 (P=0.019).CONCLUSION:CD-associated polymorphisms affected the elimination of MAP fromex vivo monocytes (NOD2),or expression of certain cytokines (ATG16L1),implying independent but contributory roles in the pathogenesis of CD.Dylan M Glubb Richard B Gearry Murray L Barclay Rebecca L Roberts John Pearson Jacqui I Keenan Judy McKenzie Robert W Bentley 2011World Journal of Gastroenterology2011,17,23:2
