2Abdominal applications of diffusion-weighted magnetic resonance imaging: Where do we stand?显示文摘Diffusion-weighted imaging (DWI) is one of the magnetic resonance imaging (MRI) sequences providing qualitative as well as quantitative information at a cellular level. It has been widely used for various applications in the central nervous system. Over the past decade, various extracranial applications of DWI have been increasingly explored, as it may detect changes even before signal alterations or morphological abnormalities become apparent on other pulse sequences. Initial results from abdominal MRI applications are promising, particularly in oncological settings and for the detection of abscesses. The purpose of this article is to describe the clinically relevant basic concepts of DWI, techniques to perform abdominal DWI, its analysis and applications in abdominal visceral MR imaging, in addition to a brief overview of whole body DWI MRI.Ajaykumar C Morani Khaled M Elsayes Peter S Liu William J Weadock Janio Szklaruk Jonathan Russell Dillman Asra Khan Thomas L Chenevert Hero K Hussain 2013World Journal of Radiology2013,5,3:12

6Enhanced expression of interleukin-18 in serum and pancreas of patients with chronic pancreatitis显示文摘AIM: To investigate interleukin-18 (IL-18) in patients with chronic panreatitis (CP). METHODS: We studied 29 patients with CP and 30 healthy controls. Peripheral blood mononuclear cells (PBMC) were isolated and incubated with 50 mmol/L ethanol, lipopolysaccharide (LPS) (doses 25 g/L, 250 g/L, 2500 g/L) and both agents for 24 h. Levels of IL-18 in the supernatants, and levels of IL-18, IL-12, interferon (IFN)-γ and soluble CD14 in the serum were analysed by ELISA technique. Expression of IL-18 in PBMC was investigated by reverse-transcription (RT)-PCR. IL-18 protein levels in CP tissue and in normal pancreas were studied by ELISA technique. IL-18 levels in PBMC and pancreatic tissue were determined by Westernblot. Im-munohistochemistry for pancreatic IL-18 expression was performed. RESULTS: In patients, IL-18 serum levels were signifi-cantly enhanced by 76% (mean: 289.9 ± 167.7 ng/L) compared with controls (mean: 165.2 ± 43.6 ng/L; P < 0.0005). IL-12 levels were enhanced by 25% in patients (18.3 ± 7.3 ng/L) compared with controls (14.7 ± 6.8ng/L, P = 0.0576) although not reaching the statistical significance. IFN-γ and soluble CD14 levels were not in-creased. In vitro, LPS stimulated significantly and dose-dependently IL-18 secretion from PBMC. Incubation with ethanol reduced LPS-stimulated IL-18 secretion by about 50%. The mRNA expression of IL-18 in PBMC and the response of PBMC to ethanol and LPS was similar in CP patients and controls. In PBMC, no significant differences in IL-18 protein levels were detected between patients and controls. IL-18 protein levels were increased in CP tissues compared to normal pancreatic tissues. IL-18 was expressed by pancreatic acinar cells and by infiltrating inflammatory cells within the pancreas. CONCLUSION: IL-18 originates from the chronically inflammed pancreas and appears to be involved in the fibrotic destruction of the organ.Alexander Schneider Stephan L Haas Ralf Hildenbrand Sren Siegmund Iris Reinhard Helmut Nakovics Manfred V Singer Peter Feick 2006World Journal of Gastroenterology2006,12,40:4

10Risk for emerging bipolar disorder, variants, and symptoms in children with attention deficit hyperactivity disorder, now grown up显示文摘AIM: To determine the prevalence of bipolar disorder(BD) and sub-threshold symptoms in children with attention deficit hyperactivity disorder(ADHD) through 14 years' follow-up, when participants were between 21-24 years old.METHODS: First, we examined rates of BD type Ⅰ?and Ⅱ diagnoses in youth participating in the NIMH-funded Multimodal Treatment Study of ADHD(MTA). We used the diagnostic interview schedule for children(DISC), administered to both parents(DISC-P) and youth(DISCY). We compared the MTA study subjects with ADHD(n = 579) to a local normative comparison group(LNCG, n = 289) at 4 different assessment points: 6, 8, 12, and 14 years of follow-ups. To evaluate the bipolar variants, we compared total symptom counts(TSC) of DSM manic and hypomanic symptoms that were generated by DISC in ADHD and LNCG subjects. Then we sub-divided the TSC into pathognomonic manic(PM) and non-specific manic(NSM) symptoms. We compared the PM and NSM in ADHD and LNCG at each assessment point and over time. We also evaluated the irritability as category A2 manic symptom in both groups and over time. Finally, we studied the irritability symptom in correlation with PM and NSM in ADHD and LNCG subjects.RESULTS: DISC-generated BD diagnosis did not differ significantly in rates between ADHD(1.89%) and LNCG 1.38%). Interestingly, no participant met BD diagnosis more than once in the 4 assessment points in 14 years. However, on the symptom level, ADHD subjects reported significantly higher mean TSC scores: ADHD 3.0; LNCG 1.7; P < 0.001. ADHD status was associated with higher mean NSM: ADHD 2.0 vs LNCG 1.1; P < 0.0001. Also, ADHD subjects had higher PM symptoms than LNCG, with PM means over all time points of 1.3 ADHD; 0.9 LNCG; P = 0.0001. Examining both NSM and PM, ADHD status associated with greater NSM than PM. However, Over 14 years, the NSM symptoms declined and changed to PM over time(df 3, 2523; F = 20.1; P < 0.0001). Finally, Irritability(BD DSM criterion-A2) rates were significantly higher in ADHD than LNCG(χ2 = 122.2, P < 0.0001), but irritability was associated more strongly with NSM than PM(df 3, 2538; F = 43.2; P < 0.0001).CONCLUSION: Individuals with ADHD do not appear to be at significantly greater risk for developing BD, but do show higher rates of BD symptoms, especially NSM. The greater linkage of irritability to NSM than to PM suggests caution when making BD diagnoses based on irritability alone as one of 2(A-level) symptoms for BD diagnosis, particularly in view of its frequent presentation with other psychopathologies.Ahmed Z Elmaadawi Peter S Jensen L Eugene Arnold Brooke SG Molina Lily Hechtman Howard B Abikoff Stephen P Hinshaw Jeffrey H Newcorn Laurence Lee Greenhill James M Swanson Cathryn A Galanter 2015World Journal of Psychiatry2015,5,4:3
11Identification of stable normalization genes for quantitative real-time PCR in porcine articular cartilage显示文摘Background: Expression levels for genes of interest must be normalized with an appropriate reference, or housekeeping gene, to make accurate comparisons of quantitative real-time PCR results. The purpose of this study was to identify the most stable housekeeping genes in porcine articular cartilage subjected to a mechanical injury from a panel of 10 candidate genes. Results: Ten candidate housekeeping genes were evaluated in three different treatment groups of mechanically impacted porcine articular cartilage. The genes evaluated were: beta actin, beta-2-microglobulin, glyceraldehyde-3-phosphate dehydrogenase, hydroxymethylbilane synthase, hypoxanthine phosphoribosyl transferase, peptidylprolyl isomerase A (cyclophilin A), ribosomal protein L4, succinate dehydrogenase flavoprotein subunit A, TATA box binding protein, and tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein-zeta polypeptide. The stability of the genes was measured using geNorm, BestKeeper, and NormFinder software. The four most stable genes measured via geNorm were (most to least stable) succinate dehydrogenase flavoprotein, subunit A, peptidylprolyl isomerase A, glyceraldehyde-3-phosphate dehydrogenase, beta actin; the four most stable genes measured via BestKeeper were glyceraldehyde-3-phosphate dehydrogenase, peptidylprolyl isomerase A, beta actin, succinate dehydrogenase flavoprotein, subunit A; and the four most stable genes measured via NormFinder were peptidylprolyl isomerase A, succinate dehydrogenase flavoprotein, subunit A, glyceraldehyde-3-phosphate dehydrogenase, beta actin. Conclusions: BestKeeper, geNorm, and NormFinder all generated similar results for the most stable genes in porcine articular cartilage. The use of these appropriate reference genes will facilitate accurate gene expression studies of porcine articular cartilage and suggest appropriate housekeeping genes for articular cartilage studies in other species.Ryan S McCulloch Melissa S Ashwell Audrey T O'Nan Peter L Mente 2012Journal of Animal Science and Biotechnology2012,3,4:2

18Prevalence and predictors of hospitalization in Crohn's disease in a prospective population-based inception cohort from 2000-2012显示文摘AIM: To analyze the prevalence, length and predictors of hospitalization in the biological era in the populationbased inception cohort from Veszprem province.METHODS: Data of 331 incident Crohn's disease(CD) patients diagnosed between January 1, 2000 and December 31, 2010 were analyzed(median age at diagnosis: 28; IQR: 21-40 years). Both in- and outpatient records were collected and comprehensively reviewed.RESULTS: Probabilities of first CD-related hospitalization and re-hospitalization were 32.3%, 45.5%,53.7% and 13.6%, 23.9%, 29.8%, respectively after one, three and five years of follow-up in Kaplan-Meier analysis. First-year hospitalizations were related to diagnostic procedures(37%), surgery or disease activity(27% and 21%). Non-inflammatory disease behavior at diagnosis(HR = 1.32, P = 0.001) and perianal disease(HR = 1.47, P = 0.04) were associated with time to first CD-related hospitalization, while disease behavior change(HR = 2.38, P = 0.002) and need for steroids(HR = 3.14, P = 0.003) were associated with time to first re-hospitalization in multivariate analyses.Early CD-related hospitalization(within the year of diagnosis) was independently associated with need for immunosuppressives(OR = 2.08, P = 0.001) and need for surgeries(OR = 7.25, P < 0.001) during the disease course.CONCLUSION: Hospitalization and re-hospitalization rates are still high in this cohort, especially during the first-year after the diagnosis. Non-inflammatory disease behavior at diagnosis was identified as the pivotal predictive factor of both hospitalization and rehospitalization.Petra A Golovics Laszlo Lakatos Michael D Mandel Barbara D Lovasz Zsuzsanna Vegh Zsuzsanna Kurti Istvan Szita Lajos S Kiss Tunde Pandur Peter L Lakatos 2015World Journal of Gastroenterology2015,21,23:2
