4Helicobacter pylori associated gastric intestinal metaplasia:Treatment and surveillance显示文摘Gastric cancer(GC) is one of the leading causes of cancer related death in the world, particularly in East Asia. According to the Correa's cancer cascade, noncardia GC is usually developed through a series of mucosal changes from non-atrophic gastritis to atrophic gastritis(AG), intestinal metaplasia(IM), dysplasia and adenocarcinoma. Atrophic gastritis and IM are therefore generally considered to be pre-neoplastic gastric lesions. Helicobacter pylori(H. pylori) infection is an important initiating and promoting step of this gastric carcinogenesis cascade. Emerging long-term data showed that eradication of H. pylori reduced the risk of subsequent cancer development. It however remains confusing whether eradication of the bacterium in individuals with pre-neoplastic gastric lesions could regress these changes as well as in preventing cancer. Whilst H. pylori eradication could likely regress AG, the presence of IM may be a point of no return in this cascade. Hence, surveillance by endoscopy may be indicated in those with extensive IM or those with incomplete IM, particularly in populations with high GC risk. The optimal interval and the best tool of surveillance endoscopy remains to be determined in future studies.Kevin Sze-Hang Liu Irene Oi-Ling Wong Wai K Leung 2016World Journal of Gastroenterology2016,22,3:23
5Intracellular signaling mechanisms regulating the activation of human eosinophils by the novel Th2 cytokine IL-33:implications for allergic inflammation显示文摘The novel interleukin(IL)-1 family cytokine IL-33 has been shown to activate T helper 2(Th2)lymphocytes,mast cells and basophils to produce an array of proinflammatory cytokines,as well as to mediate blood eosinophilia,IgE secretion and hypertrophy of airway epithelium in mice.In the present study,we characterized the activation of human eosinophils by IL-33,and investigated the underlying intracellular signaling mechanisms.IL-33 markedly enhanced eosinophil survival and upregulated cell surface expression of the adhesion molecule intercellular adhesion molecule(ICAM)-1 on eosinophils,but it suppressed that of ICAM-3 and L-selectin.In addition,IL-33 mediates significant release of the proinflammatory cytokine IL-6 and the chemokines CXCL8 and CCL2.We found that IL33-mediated enhancement of survival,induction of adhesion molecules,and release of cytokines and chemokines were differentially regulated by activation of the nuclear factor(NF)-KB,p38 mitogen-activated protein kinase(MAPK)and extracellular signal-regulated kinase(ERK)pathways.Furthermore,we compared the above IL-33 activities with two structurally and functionally related cytokines,IL-1 B and IL-18.IL-1β,but not IL-18,markedly upregulated cell surface expression of ICAM-1.IL-1βand IL-18 also significantly enhanced eosinophil survival,and induced the release of IL-6 and chemokines CXCL8 and CCL2 via the activation of the NF-κB,p38 MAPK and ERK pathways.Synergistic efects on the release of IL-6 were also observed in combined treatment withIL-1B,IL-18 and IL-33.Taken together,our findings provide insight into IL-33-mediated activation of eosinophils via differential intracellular signaling cascades in the immunopathogenesis of allergic inflammation.Joyce YS Chow Chun K Wong Phyllis FY Cheung Christopher WK Lam 2010Cellular & Molecular Immunology2010,7,1:22
6Effect of oral erythromycin on gastric and small bowel transit time of capsule endoscopy显示文摘AIM: To determine the effect of oral erythromycin on gastric and small bowel transit time of capsule endoscopy.METHODS: Consecutive patients who underwent capsule endoscopy du ring the 16-mo study period were either given 250 mg oral erythromycin, 1 h prior to swallowing the capsule endoscope or nothing. The gastric and small bowel transit time, and the small bowel image quality were compared.RESULTS: Twenty-four patients received oral erythromycin whereas 14 patients were not given any prokinetic agent.Patients who received erythromycin had a significantly lower gastric transit time than control (16 min vs70 min, P= 0.005),whereas the small bowel transit time was comparable between the two groups (227 min vs183 min, P = 0.18).Incomplete small bowel examination was found in three patients of the control group and in one patient of the erythromycin group. There was no significant difference in the overall quality of small bowel images between the two groups. A marked reduction in gastric transit time was noted in two patients who had repeat capsule endoscopy after oral erythromycin.CONCLUSION: Use of oral erythromycin significantly reduces the gastric transit time of capsule endoscopy.Wai K Leung Francis KL Chan Sara SL Fung Mei-Yin Wong Joseph JY Sung 2005World Journal of Gastroenterology2005,11,31:16
7Treatment of functional dyspepsia with sertraline:A double-blind randomized placebo-controlled pilot study显示文摘AIM:To evaluate sertraline,a selective serotonin reuptake inhibitor in the treatment of patients with functional dyspepsia.METHODS:Consecutive tertiary hospital patients with a clinical diagnosis of functional dyspepsia(FD) according to the Rome Ⅱ criteria with a Hong Kong dyspepsia index(HKDI) of greater than 16 were recruited.Patients commenced enrolment prior to the inception of the Rome Ⅲ criteria for functional dyspepsia.All patients were ethnic Chinese,had a normal upper endoscopy and were Helicobacter pylori negative prior to enrolment.Study patients were randomized to receive sertraline 50 mg or placebo daily for 8 wk.HKDI symptom scores,quality of life,hospital anxiety and depression(HAD) scale and global symptom relief were evaluated before,during and after treatment.Adverse effects were monitored during and after treatment.RESULTS:A total of 193 patients were randomized in the intention to treat(ITT),and 150 patients were included in the per protocol(PP) analysis.In both the ITT and PP,there was no difference in the primary outcome of global dyspepsia symptoms between the sertraline and placebo groups at week 8.In the ITT analysis,98 and 95 patients were randomized to the sertraline and placebo groups respectively.A total of 43 patients withdrew from the study(22.3%) by week 8,with 23 of the 24 drop-outs in the sertraline group occurring prior to week 4(95.8%).In contrast,in the placebo arm,11 of 19 patients dropped out by week 4(57.9%).Utilizing the last response carried forward to account for the drop-outs,there were no differences between the sertraline and placebo groups at baseline in terms of the HKDI,HKDI 26.08 ± 6.19 vs 26.70 ± 5.89,P = 0.433;and at week 8,HKDI 22.41 ± 6.36 vs 23.25 ± 7.30,P = 0.352 respectively.In the PP analysis,74 and 76 patients were randomized to the sertraline and placebo groups respectively.At baseline,there were no statistically significant differences between the sertraline and placebo groups,HKDI 25.83 ± 6.313 vs 27.19 ± 5.929 respectively,P = 0.233;however by week 8,patients in the sertraline group demonstrated a statistically significant difference in their Hong Kong Dyspepsia Index compared to placebo,HKDI 20.53 ± 6.917 vs 23.34 ± 7.199,P = 0.02,respectively).There was also no statistically significant difference in overall quality of life measures or the HAD scale related to treatment in either the ITT or PP analysis at week 8.CONCLUSION:This pilot study,the first to examine sertraline,a selective serotonin reuptake inhibitor,for the management of FD,did not find that it was superior to placebo.Victoria PY Tan Tin K Cheung Wai M Wong Roberta Pang Benjamin CY Wong 2012World Journal of Gastroenterology2012,18,42:14
8膨胀土地基中隧道施工对群桩影响研究显示文摘在膨胀土地基中进行隧道对群桩影响的三维离心模型试验研究,目标地层损失比为2%,着重研究引起的地基沉降槽、桩的附加沉降、附加弯矩、轴力的变化规律。试验得出:隧道开挖沉降槽空间效应明显;隧道开挖从-0.75D至1.25D时,桩附加沉降呈线性增长,隧道开挖至1.25D以后,桩依然沉降明显。前桩与后桩沉降值不同,桩帽会出现倾斜;前桩上部出现负附加弯矩而下部出现正附加弯矩,而后桩仅在下部出现正附加弯矩;前桩附加弯矩最大值出现在隧道轴线附近,且比后桩附加弯矩大得多;前桩附加轴力随着隧道的开挖而增加,且每步最大值在隧道轴线附近。后桩的轴力也随隧道的开挖而增加,但每步最大值出现在桩顶附近。马少坤 WONG K S 吕虎 吴宏伟 赵乃峰 2013岩土力学2013,34,11:8
9双隧道对群桩影响的三维离心模型试验研究显示文摘在膨胀土地基中进行了双隧道对群桩影响的三维离心模型试验,目标地层损失比为2%,着重研究引起的地基沉降槽、附加弯矩、轴力的变化规律。试验得出:膨胀土地基中每个隧道开挖形成的地表沉降槽仍符合Peck高斯曲线,双隧道共同作用形成的沉降槽可以看作是每个隧道单独作用形成的沉降槽的叠加;两个隧道开挖引起的前后桩弯矩规律类似,最大附加弯矩均出现在拱冠附近,但存在明显的前桩遮拦效应;随着第一个隧道开挖的临近及远离,前后桩轴力会发生明显不同变化,而第二个隧道影响明显不同,附加轴力最大值约为工作荷载的10%。马少坤 吕虎 Wong K S 吴宏伟 赵乃峰 2013岩土工程学报2013,35,7:8
10Molecular mechanism and functional consequences of lansoprazole-mediated heme oxygenase-1 induction显示文摘AIM:To investigate the molecular mechanism and functional consequences of heme oxygenase-1(HO-1) activation by lansoprazole in endothelial cells and macrophages. METHODS:Expression of HO-1 mRNA was analyzed by Northern blotting.Western blotting was used to determine the HO-1 and ferritin protein levels. NADPH-dependent reactive oxygen species(ROS) formation was measured with lucigenin-enhanced chemiluminescence.HO-1 promoter activity in mouse fibroblasts,stably transfected with a 15-kb HO-1 gene that drives expression of the reporter gene luciferase, was assessed using in vivo bioluminescence imaging. RESULTS:Lansoprazole increased HO-1 mRNA levels in endothelial cells and HO-1 protein levelsin macrophages.In addition,lansoprazole-induced ferritin protein levels in both cell systems.Moreover, induction of the antioxidant proteins HO-1 and ferritin by lansoprazole was followed by a decrease in NADPH- mediated ROS formation.The radical scavenging properties of lansoprazole were diminished in the presence of the HO inhibitor,chromium mesoporphyrin IX.Induction of HO-1 gene expression by lansoprazole was not related to oxidative stress or to the activation of the mitogen-activated protein kinase pathway. However,the phosphatidylinositol 3-kinase inhibitor LY294002 showed a concentration-dependent inhibition of HO-1 mRNA and promoter activity. CONCLUSION:Activation of HO-1 and ferritin may account for the gastric protection of lansoprazole and is dependent on a pathway blocked by LY294002.Stephanie Schulz-Geske Kati Erdmann Ronald J Wong David K Stevenson Henning Schrder Nina Grosser 2009World Journal of Gastroenterology2009,15,35:7

12Activation of human fibroblast-like synoviocytes by uric acid crystals in rheumatoid arthritis显示文摘Hyperuricemia-mediated uric acid crystal formation may cause joint inflammation and provoke the destruction of joints through the activation of inflammasome-mediated innate immune responses.However,the immunopathological effects and underlying intracellular regulatory mechanisms of uric acid crystal-mediated activation of fibroblast-like synoviocytes(FLS)in rheumatoid arthritis(RA)have not been elucidated.Therefore,we investigated the in vitro effects of monosodium urate crystals,alone or in combination with the inflammatory cytokines tumor-necrosis factor(TNF)-a or interleukin(IL)-1b,on the activation of human FLS from RA patients and normal control subjects and the underlying intracellular signaling mechanisms of treatment with these crystals.Monosodium urate crystals were able to significantly increase the release of the inflammatory cytokine IL-6,the chemokine CXCL8 and the matrix metalloproteinase(MMP)-1 from both normal and RA-FLS(all P,0.05).Moreover,the additive or synergistic effect on the release of IL-6,CXCL8 and MMP-1 from both normal and RA-FLS was observed following the combined treatment with monosodium urate crystals and TNF-a or IL-1b.Further experiments showed that the release of the measured inflammatory cytokine,chemokine and MMP-1 stimulated by monosodium urate crystals were differentially regulated by the intracellular activation of extracellular signal-regulated kinase and c-Jun N-terminal kinase pathways but not the p38 mitogen-activated protein kinase pathway.Our results therefore provide a new insight into the uric acid crystal-activated immunopathological mechanisms mediated by distinct intracellular signal transduction pathways leading to joint inflammation in RA.Da P Chen Chun K Wong Lai S Tam Edmund K Li Christopher WK Lam 2011Cellular & Molecular Immunology2011,8,6:5
13Role of stem cell therapies in treating chronic wounds:A systematic review显示文摘BACKGROUND The impairment of cutaneous wound healing results in chronic,non-healing wounds that are caused by altered wound environment oxygenation,tissue injury,and permissive microbial growth.Current modalities for the treatment of these wounds inadequately address the complex changes involved in chronic wound pathogenesis.Consequently,stem cell therapies have emerged as a potential therapeutic modality to promote cutaneous regeneration through trophic and paracrine activity.AIM To investigate current literature regarding use of stem cell therapies for the clinical treatment of chronic,non-healing wounds.METHODS PubMed,EMBASE,Cochrane Library,Web of Science,and Scopus were queried with combinations of the search terms“mesenchymal stem cells,”“adult stem cells,”“embryonic stem cells,”“erythroid precursor cells,”“stem cell therapies,”and“chronic wounds”in order to find relevant articles published between the years of 2000 and 2019 to review a 20-year experience.Reference lists from the articles were reviewed to identify additional pertinent articles.Retrieved manuscripts(reviews,case reports/series,retrospective/prospective studies,and clinical trials)were evaluated by the authors for their depiction of clinical stem cell therapy use.Data were extracted from the articles using a standardized collection tool.RESULTS A total of 43 articles describing the use of stem cell therapies for the treatment of chronic wounds were included in this review.While stem cell therapies have been explored in in vitro and in vivo applications in the past,recent efforts are geared towards assessing their clinical role.A review of the literature revealed that adipose-derived stem cells,bone marrow-derived stem cells,bone marrowderived mononuclear cells,epidermally-derived mesenchymal stem cells,fibroblast stem cells,keratinocyte stem cells,placental mesenchymal stem cells,and umbilical cord mesenchymal stem cells have all been employed in the treatment of chronic wounds of various etiologies.Most recently,embryonic stem cells have emerged as a novel stem cell therapy with the capacity for multifaceted germ cell layer differentiation.With the capacity for self-renewal and differentiation,stem cells can enrich existing cell populations in chronic wounds in order to overcome barriers impeding the progression of wound healing.Further,stem cell therapies can be utilized to augment cell engraftment,signaling and activity,and resultant patient outcomes.CONCLUSION Assessing observed clinical outcomes,potential for stem cell use,and relevant therapeutic challenges allows wound care stakeholders to make informed decisions regarding optimal treatment approaches for their patients’chronic wounds.Anjali C Raghuram Roy P Yu Andrea Y Lo Cynthia J Sung Melissa Bircan Holly J Thompson Alex K Wong 2020World Journal of Stem Cells2020,12,7:5
14Hepatocellular carcinoma in patients with non-alcoholic fatty liver disease显示文摘Nonalcoholic fatty liver disease(NAFLD) is the most common chronic liver disease in the United States and represents an increasingly important etiology of hepatocellular carcinoma(HCC) with annual cumulative incidence rates ranging from 2% to 12% in cohorts of NAFLD cirrhosis. While the risk of progression of NAFLD to HCC remains higher among patients with fibrosis or cirrhosis, an increasing amount of literature describes NAFLD-HCC as a disease that can occur in the absence of cirrhosis. Efforts to characterize the pathogenesis of NAFLD-HCC have suggested mechanisms that strongly associate with states of hyperinsulinemia and chronic inflammation, cellular mechanisms including adaptive immune responses and hepatic progenitor cell populations, and genetic polymorphisms including mutations of PNPLA3. Current literature describes NAFLD-HCC mostly as a disease of late presentation with lower rates of receipt of curative therapy and worse prognosis. However, a growing body of evidence has reported comparable and potentially more favorable disease-free and overall survival rates among patients with NAFLD-HCC after receipt of curative treatment. This review summarizes current evidence of epidemiology, pathophysiology, disease presentation, demand and receipt of curative therapy, post-treatment outcomes, and overall survival of NAFLD-associated HCC.Carrie R Wong Mindie H Nguyen Joseph K Lim 2016World Journal of Gastroenterology2016,22,37:5

16Recurrent ectopic pancreatitis of the jejunum and mesentery over a 30-year period显示文摘BACKGROUND:Ectopic pancreas is defined as pancreatic tissue found outside its usual anatomical position,with no ductal or vascular communication with the native pancreas. We describe a case of ectopic pancreas of the small bowel and mesentery causing recurrent episodes of pancreatitis, initially suspected on computed tomography(CT)and magnetic resonance cholangiopancreatography(MRCP),and confirmed on histological review of the resection. METHODS:A 67-year-old woman presented with clinical symptoms and biochemical evidence of pancreatitis.She had similar episodes over the past 30 years with unrevealing investigations,and was concluded to have idiopathic pancreatitis. She underwent CT and MRCP,with findings suggestive of ectopic pancreas,a diagnosis confirmed on histology of the resection. RESULTS:MRCP identified a mass in the proximal small bowel mesentery isointense to the native pancreas,with a small duct draining into a proximal jejunal loop.The resected specimen consisted of normal parenchyma with lobulated acinar tissue with scattered islets of Langerhans,an occasional ductular structure,and admixed areas of adipose tissue.The patient remained asymptomatic with normal biochemistry six months post-operatively. CONCLUSION:In an individual with abdominal pain,elevated serum amylase/lipase,but imaging findings of a normal native pancreas,ectopic pancreatitis should be considered,and can be evaluated by CT and MRCP.John CT Wong Charlotte Robinson Edward C Jones Alison Harris Charles Zwirewich Robert Wakefield Richard K Simons Eric M Yoshida 2011Hepatobiliary & Pancreatic Diseases International2011,10,2:4

20Atherosclerosis imaging using 3D black blood TSE SPACE vs 2D TSE显示文摘AIM: To compare 3D Black Blood turbo spin echo(TSE)sampling perfection with application-optimized contrast using different flip angle evolution(SPACE) vs 2D TSE in evaluating atherosclerotic plaques in multiple vascular territories. METHODS: The carotid, aortic, and femoral arterial walls of 16 patients at risk for cardiovascular or atherosclerotic disease were studied using both 3D black blood magnetic resonance imaging SPACE and conventional 2D multi-contrast TSE sequences using a consolidated imaging approach in the same imaging session. Qualitative and quantitative analyses were performed on the images. Agreement of morphometric measurements between the two imaging sequences was assessed using a two-sample t-test, calculation of the intra-class correlation coefficient and by the method of linear regression and Bland-Altman analyses. RESULTS: No statistically significant qualitative differences were found between the 3D SPACE and 2D TSE techniques for images of the carotids and aorta. For images of the femoral arteries, however, there were statistically significant differences in all four qualitative scores between the two techniques. Using the current approach, 3D SPACE is suboptimal for femoral imaging. However, this may be due to coils not being optimized for femoral imaging. Quantitatively, in our study, higher mean total vessel area measurements for the 3D SPACE technique across all three vascular beds were observed. No significant differences in lumen area for both the right and left carotids were observed between the two techniques. Overall, a significant-correlation existed between measures obtained between the two approaches. CONCLUSION: Qualitative and quantitative measurements between 3D SPACE and 2D TSE techniques are comparable. 3D-SPACE may be a feasible approach in the evaluation of cardiovascular patients.Stephanie K Wong Motunrayo Mobolaji-Iawal Leron Arama Joy Cambe Sylvia Biso Nadia Alie Zahi A Fayad Venkatesh Mani 2014World Journal of Radiology2014,6,5:3
