1Non-alcoholic fatty liver disease and the metabolic syndrome:An update显示文摘Sedentary lifestyle and poor dietary choices are leading to a weight gain epidemic in westernized countries, subsequently increasing the risk for developing the metabolic syndrome and nonalcoholic fatty liver disease (NAFLD). NAFLD is estimated to affect approximate 30% of the general US population and is considered the hepatic manifestation of the metabolic syndrome. Recent findings linking the components of the metabolic syndrome with NAFLD and the progression to nonalcoholic steatohepatitis (NASH) will be reviewed; in particular, the role of visceral adipose tissue, insulin resistance, and adipocytokines in the exacerbation of these conditions. While no therapy has been proven effective for treating NAFLD/NASH, common recommendations will be discussed.R Scott Rector John P Thyfault Yongzhong Wei Jamal A Ibdah 2008World Journal of Gastroenterology2008,14,2:60
2Nonalcoholic fatty liver disease and mitochondrial dysfunction显示文摘Nonalcoholic fatty liver disease (NAFLD) includes hepatic steatosis, nonalcoholic steatohepatitis (NASH), fibrosis, and cirrhosis. NAFLD is the most common liver disorder in the United States and worldwide. Due to the rapid rise of the metabolic syndrome, the prevalence of NAFLD has recently dramatically increased and will continue to increase. NAFLD has also the potential to progress to hepatocellular carcinoma (HCC) or liver failure. NAFLD is strongly linked to caloric overconsumption, physical inactivity, insulin resistance and genetic factors. Although significant progress in understanding the pathogenesis of NAFLD has been achieved in years, the primary metabolic abnormalities leading to lipid accumulation within hepatocytes has remained poorly understood. Mitochondria are critical metabolic organelles serving as 'cellular power plants'. Accumulating evidence indicate that hepatic mitochondrial dysfunction is crucial to the pathogenesis of NAFLD. This review is focused on the significant role of mitochondria in the development of NAFLD.Yongzhong Wei R Scott Rector John P Thyfault Jamal A Ibdah 2008World Journal of Gastroenterology2008,14,2:32
3Prospective randomized controlled trial evaluating cap-assisted colonoscopy vs standard colonoscopy显示文摘AIM: To study the significance of cap-fitted colonoscopy in improving cecal intubation time and polyp detection rate. METHODS: This study was a prospective randomized controlled trial conducted from March 2008 to February 2009 in a tertiary referral hospital at Sydney. The primary end point was cecal intubation time and the secondary endpoint was polyp detection rate. Consecutive cases of total colonoscopy over a 1-year period were recruited. Randomization into either standard colonoscopy (SC) or cap-assisted colonoscopy (CAC) was performed after consent was obtained. For cases randomized to CAC, one of the three sizes of cap was used: D-201-15004 (with a diameter of 15.3 mm), D-201-14304 (14.6 mm) and D-201-12704 (13.0 mm). All of these caps were produced by Olympus Medical Systems, Japan. Independent predictors for faster cecal time and better polyp detection rate were also determined from this study. RESULTS: There were 200 cases in each group. There was no signif icant difference in terms of demographic characteristics between the two groups. CAC, when compared to the SC group, had no signif icant difference in terms of cecal intubation rate (96.0% vs 97.0%, P = 0.40) and time (9.94 ± 7.05 min vs 10.34 ± 6.82 min, P = 0.21), or polyp detection rate (32.8% vs 31.3%, P = 0.75). On the subgroup analysis, there was no significant difference in terms of cecal intubation time by trainees (88.1% vs 84.8%, P = 0.40), ileal intubation rate (82.5% vs 79.0%, P = 0.38) or total colonoscopy time (23.24 ± 13.95 min vs 22.56 ± 9.94 min, P = 0.88). On multivariate analysis, the independent determinants of faster cecal time were consultant-performed procedures (P < 0.001), male patients (P < 0.001), non-usage of hyoscine (P < 0.001) and better bowel preparation (P = 0.01). The determinants of better polyp detection rate were older age (P < 0.001), no history of previous abdominal surgery (P = 0.04), patients not having esophagogastroduodenoscopy in the same setting (P = 0.003), trainee-performed procedures (P = 0.01), usage of hyoscine (P = 0.01) and procedures performed for polyp follow-up (P = 0.01). The limitations of the study were that it was a single-center experience, no blinding was possible, and there were a large number of endoscopists. CONCLUSION: CAC did not signif icantly different from SC in term of cecal intubation time and polyp detection rate.Hoi-Poh Tee Crispin Corte Hamdan Al-Ghamdi Emilia Prakoso John Darke Raman Chettiar Wassim Rahman Scott Davison Sean P Griffin Warwick S Selby Arthur J Kaffes 2010World Journal of Gastroenterology2010,16,31:10

5Sacroiliac joint stability: Finite element analysis of implant number, orientation, and superior implant length显示文摘AIM To analyze how various implants placement variables affect sacroiliac(SI) joint range of motion. METHODS An experimentally validated finite element model of the lumbar spine and pelvis was used to simulate a fusion of the SI joint using various placement configurations of triangular implants(iF use Implant System~?). Placement configurations were varied by changing implant orientation, superior implant length, and number of implants. The range of motion of the SI joint was calculated using a constant moment of 10 N-m with a follower load of 400 N. The changes in motion were compared between the treatment groups to assess how the different variables affected the overall motion of the SI joint. RESULTS Transarticular placement of 3 implants with superior implants that end in the middle of the sacrum resulted in the greatest reduction in range of motion(flexion/extension = 73%, lateral bending = 42%, axial rotation = 72%). The range of motions of the SI joints were reduced with use of transarticular orientation(9%-18%) when compared with an inline orientation. The use of a superior implant that ended mid-sacrum resulted in median reductions of(8%-14%) when compared with a superior implant that ended in the middle of the ala. Reducing the number of implants, resulted in increased SI joint range of motions for the 1 and 2 implant models of 29%-133% and 2%-39%, respectively,when compared with the 3 implant model.CONCLUSION Using a validated finite element model we demonstrated that placement of 3 implants across the SI joint using a transarticular orientation with superior implant reaching the sacral midline resulted in the most stable construct. Additional clinical studies may be required to confirm these results.Derek P Lindsey Ali Kiapour Scott A Yerby Vijay K Goel 2018World Journal of Orthopedics2018,9,3:3
6Effect of fiber supplementation on the microbiota in critically ill patients显示文摘AIM:To determine tolerance to fiber supplementation of semi-elemental tube feeds in critically ill patients and measure its effect on colonic microbiota and fermentation.METHODS:Thirteen intensive care unit patients receiving jejunal feeding with a semi-elemental diet for predominantly necrotizing pancreatitis were studied.The study was divided into 2 parts:first,short-term (3-9 d)clinical tolerance and colonic fermentation as assessed by fecal short chain fatty acid(SCFA)concentrations and breath hydrogen and methane was measured in response to progressive fiber supplementation increasing from 4 g tid up to normal requirement levels of 8 g tid;second,4 patients with diarrhea were studied for 2-5 wk with maximal supplementation to additionally assess its influence on fecal microbiota quantitated by quantitative polymerase chain reaction (qPCR)of microbial 16S rRNA genes and Human Intestinal Tract Chip(HITChip)microarray analysis.Nearly all patients were receiving antibiotics(10/13)and acid suppressants(11/13)at some stage during the studies.RESULTS:In group 1,tolerance to progressive fiber supplementation was good with breath hydrogen and methane evidence(P=0.008 and P<0.0001,respectively)of increased fermentation with no exacerbation of abdominal symptoms and resolution of diarrhea in 2 of 4 patients.In group 2 before supplementation,fecal microbiota mass and their metabolites,SCFA,were dramatically lower in patients compared to healthy volunteers.From qPCR and HITChip analyses we calculated that there was a 97%reduction in the predominant potential butyrate producers and starch degraders.Following 2-5 wk of fiber supplementation there was a significant increase in fecal SCFA(acetate 28.4±4.1μmol/g to 42.5±3.1μmol/g dry weight,P=0.01;propionate 1.6±0.5 vs 6.22±1.1,P=0.006 and butyrate 2.5±0.6 vs 5.9±1.1,P=0.04)and microbial counts of specific butyrate producers,with resolution of diarrhea in 3 of 4 patients.CONCLUSION:Conventional management of critically ill patients,which includes the use of elemental diets and broad-spectrum antibiotics,was associated with gross suppression of the colonic microbiota and their production of essential colonic fuels,i.e.,SCFA.Our investigations show that fiber supplementation of the feeds has the potential to improve microbiota mass and function,thereby reducing the risks of diarrhea due to dysbiosis.Stephen JD O'Keefe Junhai Ou James P DeLany Scott Curry Erwin Zoetendal H Rex Gaskins Scott Gunn 2011World Journal of Gastrointestinal Pathophysiology2011,2,6:3
7纳米碳化钒强化TWIP钢加工硬化机制研究显示文摘弥散分布的纳米碳化钒颗粒能明显提高TWIP钢的屈服强度,但同时将在一定程度上降低加工硬化率。采用一个修正的物理模型来研究纳米碳化钒颗粒对一种实验室等级的FeMnC奥氏体TWIP钢加工硬化率的影响。试验发现在塑性变形过程中弥散分布的纳米碳化钒颗粒会加快位错累积速率,但也会降低孪晶形成速率。与不含析出相的TWIP钢相比,在小应变时含纳米碳化钒颗粒的TWIP钢加工硬化率较高,但随着应变量的增加其硬化率减小的速度高于不含析出相的TWIP钢,因此在高应变条件下含纳米碳化钒颗粒的TWIP显示出较低的钢加工硬化率。Liang ZY Huang M X Yen H W Scott C P 魏世同(翻译) 2014钢铁钒钛2014,35,1:3
