2Osteopontin as potential biomarker and therapeutic target in gastric and liver cancers显示文摘Gastric cancer and liver cancer are among the most common malignancies and the leading causes of death worldwide,due to late detection and high recurrence rates.Today,these cancers have a heavy socioeconomic burden,for which a full understanding of their pathophysiological features is warranted to search for promising biomarkers and therapeutic targets.Osteopontin (OPN) is overexpressed in most patients with gastric and liver cancers.Over the past decade,emerging evidence has revealed a correlation of OPN level and clinicopathological features and prognosis in gastric and liver cancers,indicating its potential as an independent prognostic indicator in such patients.Functional studies have verified the potential of OPN knockdown as a therapeutic approach in vitro and in vivo .Furthermore,OPN mediates multifaceted roles in the interaction between cancer cells and the tumor microenvironment,in which many details need further exploration.OPN signaling results in various functions,including prevention of apoptosis,modulation of angiogenesis,malfunction of tumor-associated macrophages,degradation of extracellular matrix,activation of phosphoinositide 3-kinase-Akt and nuclear factor-κB pathways,which lead to tumor formation and progression,particularly in gastric and liver cancers.This editorial aims to review recent findings on alteration in OPN expression and its clinicopathological associations with tumor progression,its potential as a therapeutic target,and putative mechanisms in gastric and liver cancers.Better understanding of the implications of OPN in tumorigenesis might facilitate development of therapeutic regimens to benefit patients with these deadly malignancies.Dong-Xing Cao Zhi-Jie Li Xiao-Ou Jiang Yick Liang Lum Ester Khin Nikki P Lee Guo-Hao Wu John M Luk 2012World Journal of Gastroenterology2012,18,30:29

4Update on hepatocellular carcinoma: Pathologists' review显示文摘Histopathologic diversity and several distinct histologic subtypes of hepatocellular carcinoma(HCC) are well-recognized. Recent advances in molecular pathology and growing knowledge about the biology associated with distinct histologic features and immuno-profile in HCC allowed pathologists to update classifications. Improving sub-classification will allow for more clinically relevant diagnoses and may allow for stratification into biologically meaningful subgroups. Therefore, immuno-histochemical and molecular testing are not only diagnostically useful, but also are being incorporated as crucial components in predicting prognosis of the patients with HCC. Possibilities of targeted therapy are being explored in HCC, and it will be important for pathologists to provide any data that may be valuable from a theranostic perspective. Herein, we review and provide updates regarding the pathologic sub-classification of HCC.Pathologic diagnostic approach and the role of biomarkers as prognosticators are reviewed. Further, the histopathology of four particular subtypes of HCC:Steatohepatitic, clear cell, fibrolamellar and scirrhous-and their clinical relevance, and the recent consensus on combined HCC-cholangiocarcinoma is summarized. Finally, emerging novel biomarkers and new approaches to HCC stratification are reviewed.Tony El Jabbour Stephen M Lagana Hwajeong Lee 2019World Journal of Gastroenterology2019,25,14:25

6Management of distal humeral coronal shear fractures显示文摘Coronal shear fractures of the distal humerus are rare,complex fractures that can be technically challenging to manage. They usually result from a low-energy fall and direct compression of the distal humerus by the radial head in a hyper-extended or semi-flexed elbow or from spontaneous reduction of a posterolateral subluxation or dislocation. Due to the small number of soft tissue attachments at this site, almost all of these fractures are displaced. The incidence of distal humeral coronal shear fractures is higher among women because of the higher rate of osteoporosis in women and the difference in carrying angle between men and women. Distal humeral coronal shear fractures may occur in isolation, may be part of a complex elbow injury, or may be associated with injuries proximal or distal to the elbow. An associated lateral collateral ligament injury is seen in up to 40% and an associated radial head fracture is seen in up to 30% of these fractures. Given the complex nature of distal humeral coronal shear fractures, there is preference for operative management. Operative fixation leads to stable anatomic reduction, restores articular congruity, and allows initiation of early range-of-motion movements in the majority of cases. Several surgical exposure and fixation techniques are available to reconstruct the articular surface fol owing distal humeral coronal shear fractures. The lateral extensile approach and fixation with countersunk headless compression screws placed in an anterior-to-posterior fashion are commonly used. We have found a two-incision approach(direct anterior and lateral) that results in less soft tissue dissection and better outcomes than the lateral extensile approach in our experience. Stiffness, pain, articular incongruity, arthritis, and ulnohumeral instability may result if reduction is non-anatomic or if fixation fails.Shahram S Yari Nathan L Bowers Miguel A Craig Lee M Reichel 2015World Journal of Clinical Cases2015,3,5:15
7Liver disease in pregnancy显示文摘Liver diseases in pregnancy may be categorized into liver disorders that occur only in the setting of pregnancy and liver diseases that occur coincidentally with pregnancy. Hyperemesis gravidarum, preeclampsia/eclampsia, syndrome of hemolysis, elevated liver tests and low platelets (HELLP), acute fatty liver of pregnancy, and intrahepatic cholestasis of pregnancy are pregnancy-specific disorders that may cause elevations in liver tests and hepatic dysfunction. Chronic liver diseases, including cholestatic liver disease, autoimmune hepatitis, Wilson disease, and viral hepatitis may also be seen in pregnancy. Management of liver disease in pregnancy requires collaboration between obstetricians and gastroenterologists/hepatologists. Treatment of pregnancy-specific liver disorders usually involves delivery of the fetus and supportive care, whereas management of chronic liver disease in pregnancy is directed toward optimizing control of the liver disorder. Cirrhosis in the setting of pregnancy is less commonly observed but offers unique challenges for patients and practitioners. This article reviews the epidemiology, pathophysiology, diagnosis, and management of liver diseases seen in pregnancy.Noel M Lee Carla W Brady 2009World Journal of Gastroenterology2009,15,8:13
8Advances in surgical management for locally recurrent rectal cancer: How far have we come?显示文摘Locally recurrent rectal cancer(LRRC) is a complex disease with far-reaching implications for the patient. Until recently, research was limited regarding surgical techniques that can increase the ability to perform an en bloc resection with negative margins. This has changed in recent years and therefore outcomes for these patients have improved. Novel radical techniques and adjuncts allow for more radical resections thereby improving the chance of negative resection margins and outcomes. In the past contraindications to surgery included anterior involvement of the pubic bone, sacral invasions above the level of S2/S3 and lateral pelvic wall involvement. However, current data suggests that previously unresectable cases may now be feasible with novel techniques, surgical approaches and reconstructive surgery. The publications to date have only reported small patient pools with the research conducted by highly specialised units. Moreover, the short and long-term oncological outcomes are currently under review. Therefore although surgical options for LRRC have expanded significantly, one should balance the treatment choices available against the morbidity associated with the procedure and select the right patient for it.Daniel Jin-Keat Lee Peter M Sagar Gaitri Sadadcharam Kok-Yang Tan 2017World Journal of Gastroenterology2017,23,23:12

10Dickkopfs and Wnt/β-catenin signalling in liver cancer显示文摘Liver cancer is the fifth and seventh most common cause of cancer in men and women,respectively.Wnt/β-catenin signalling has emerged as a critical player in both the development of normal liver as well as an oncogenic driver in hepatocellular carcinoma(HCC).Based on the current understanding,this article summarizes the possible mechanisms for the aberrant activation of this pathway with specific focus on HCC.Furthermore,we will discuss the role of dickkopfs(DKKs)in regulating Wnt/β-catenin signalling,which is poorly understood and understudied.DKKs are a family of secreted proteins that comprise at least four members,namely DKK1-DKK4,which act as inhibitors of Wnt/β-catenin signalling.Nevertheless,not all members antagonize Wnt/β-catenin signalling.Their functional significance in hepatocarcinogenesis remains to be further characterized for which these studies should provide new insights into the regulatory role of DKKs in Wnt/β-catenin signalling in hepatic carcinogenesis.Because of the important oncogenic roles,there are an increasing number of therapeutic molecules targetingβ-catenin and the Wnt/β-catenin pathway for potential therapy of HCC.Sarwat Fatima Nikki P Lee John M Luk 2011World Journal of Clinical Oncology2011,2,8:11
11Factors associated with incomplete small bowel capsule endoscopy studies显示文摘AIM:To identify patient risk factors associated with incomplete small bowel capsule endoscopy(CE) studies.METHODS:Data from all CE procedures performed at St.Paul's Hospital in Vancouver,British Columbia,Canada,between December 2001 and June 2008 were collected and analyzed on a retrospective basis.Data collection for complete and incomplete CE study groups included patient demographics as well as a number of potential risk factors for incomplete CE including indication for the procedure,hospitalization,diabetes mellitus with or without end organ damage,limitations in mobility,renal insufficiency,past history of bowel obstruction,abdominal surgery,abdominal radiation therapy and opiate use.Risk factors were analyzed using a univariable and multivariable logistic regression model.RESULTS:From a total of 535 CE procedures performed,158 were incomplete(29.5%).The univariable analysis showed that CE procedures performed for overt gastrointestinal bleeding(P = 0.002),and for patients with a prior history of abdominal surgery(P = 0.023) or bowel obstruction(P = 0.023) were significantly associated with incomplete CE studies.Patients on opiate medications(P = 0.094) as well as hospitalized patients(P = 0.054) were not statistically significant,but did show a trend towards incomplete CE.The multivariable analysis showed that independent risk factors for an incomplete CE procedure include prior history of bowel obstruction [odds ratios(OR) 2.77,P = 0.02,95% confidence intervals(CI):1.17-6.56] and procedures performed for gastrointestinal bleeding(Occult OR 2.04,P = 0.037,95% CI:1.04-4.02 and Overt OR 2.69,P = 0.002,95% CI:1.44-5.05).Patients with a prior history of abdominal surgery(OR 1.46,P = 0.068,95% CI:0.97-2.19),those taking opiate medications(OR 1.54,P = 0.15,95% CI:0.86-2.76) and hospitalized patients(OR 1.82,P = 0.124,95% CI:0.85-3.93) showed a trend towards statistical significance.CONCLUSION:We have identified a number of risk factors for incomplete CE procedures that can be used to risk-stratify patients and guide interventions to improve completion rates.Mitchell M Lee Andrew Jacques Eric Lam Ricky Kwok Pardis Lakzadeh Ajit Sandhar Brandon Segal Sigrid Svarta Joanna Law Robert Enns 2010World Journal of Gastroenterology2010,16,42:10

13Dual destructive and protective roles of adaptive immunity in neurodegenerative disorders显示文摘Inappropriate T cell responses in the central nervous system(CNS)affect the pathogenesis of a broad range of neuroinflammatory and neurodegenerative disorders that include,but are not limited to,multiple sclerosis,amyotrophic lateral sclerosis,Alzheimer’s disease and Parkinson’s disease.On the one hand immune responses can exacerbate neurotoxic responses;while on the other hand,they can lead to neuroprotective outcomes.The temporal and spatial mechanisms by which these immune responses occur and are regulated in the setting of active disease have gained significant recent attention.Spatially,immune responses that affect neurodegeneration may occur within or outside the CNS.Migration of antigen-specific CD4+T cells from the periphery to the CNS and consequent immune cell interactions with resident glial cells affect neuroinflammation and neuronal survival.The destructive or protective mechanisms of these interactions are linked to the relative numerical and functional dominance of effector or regulatory T cells.Temporally,immune responses at disease onset or during progression may exhibit a differential balance of immune responses in the periphery and within the CNS.Immune responses with predominate T cell subtypes may differentially manifest migratory,regulatory and effector functions when triggered by endogenous misfolded and aggregated proteins and cell-specific stimuli.The final result is altered glial and neuronal behaviors that influence the disease course.Thus,discovery of neurodestructive and neuroprotective immune mechanisms will permit potential new therapeutic pathways that affect neuronal survival and slow disease progression.Kristi M Anderson Katherine E Olson Katherine A Estes Ken Flanagan Howard E Gendelman R Lee Mosley 2014Translational Neurodegeneration2014,3,1:8

15Lubiprostone vs Senna in postoperative orthopedic surgery patients with opioid-induced constipation:A double-blind,active-comparator trial显示文摘AIM:To investigate the efficacy of lubiprostone compared to Senna on bowel symptoms and constipation in post-operative orthopedic patients treated with opioids.METHODS:In this double blind,randomized,active comparator trial,adults who required opioids for analgesia following orthopedic procedures and who were admitted in inpatient rehabilitation were randomized following baseline assessments to lubiprostone(Amitza),orally twice aday or Senna(generic)two capsules administered daily for six days.Subjects were assessed using the patient assessment of constipation(PAC)-symptoms(PAC-SYM)and the PAC-quality of life(PAC-QOL)scales measured at baseline and Day 7;Subjects were assessed daily for secondary measures included the Bristol stool scale bowel consistency,specific bowel symptom score(Nausea,cramping,straining,completeness,abdominal pain,time per lavatory attempt,assistance needed),adverse events and rescue medications required.Function was measured using the functional independence measure(FIM)at admission and discharge;length of stay(LOS)and missed treatments due to gastrointestinal symptoms were also assessed.RESULTS:64 adults were enrolled;56 participants(28 in each group)had baseline and follow up measures and were included in the intention to treat(ITT)analyses.43 participants completed the study,21 in the active lubiprostone and 22 in the active Senna group.The mean age of the participants was 71.5years(SD=11.4 years,range:28-96 years).In the ITT analyses,participants showed significant improvement in bowel symptoms as measured by the PACSYM(mean±SD,-0.28±0.60,range:-1-2.33)and PAC-QOL(mean±SD,0.33±0.81,range:-1.5-2.0)over time,but there were no significant differences between the lubiprostone and Senna groups in mean change in the PAC-SYM(-0.20±0.60 vs-0.36±0.61,P=0.61 respectively)or the PAC-QOL(0.29±0.76 vs0.37±0.87,P=0.61 respectively).The mean change in each bowel symptom also did not significantly differ between treatment groups on ITT analyses,except for completeness of bowel movement,with the Senna group showing greater negative mean change in bowel movement completeness(-0.56±1.01 vs-2.00±1.41,P=0.03)and for reduction of abdominal pain,favoring Senna(-0.14±0.73 vs-0.73±1.08,P=0.04).Fifteen(75%)participants in the lubiprostone and in the Senna group requested rescue treatments.Participants made significant functional improvement from admission to discharge over a median LOS of 12 d,with a mean FIM change of 29.13±13.58 and no significant between group differences(27.0±9.2 vs 31.5±16.6,P=0.27).CONCLUSION:Both lubiprostone and Senna improved constipation-related symptoms and QOL in opioid-induced constipation,with no significant between-group differences.Christina M Marciniak Santiago Toledo Jungwhalia Lee Michael Jesselson Jillian Bateman Benjamin Grover Joy Tierny 2014World Journal of Gastroenterology2014,20,43:7
16Nationwide trends and predictors of inpatient mortality in 83884 transjugular intrahepatic portosystemic shunt显示文摘AIM: To evaluate and validate the national trends and predictors of in-patient mortality of transjugular intrahepatic portosystemic shunt(TIPS) in 15 years.METHODS: Using the National Inpatient Sample which is a part of Health Cost and Utilization Project, we identified a discharge-weighted national estimate of 83884 TIPS procedures performed in the United States from 1998 to 2012 using international classification of diseases-9 procedural code 39.1. The demographic, hospital and co-morbility data were analyzed using a multivariant analysis. Using multi-nominal logistic regression analysis, we determined predictive factors related to increases in-hospital mortality. Comorbidity measures are in accordance to the Comorbidity Software designed by the Agency for Healthcare Research and Quality.RESULTS: Overall, 12.3% of patients died during hospitalization with downward trend in-hospitalmortality with the mean length of stay of 10.8 ± 13.1 d. Notable, African American patients(OR = 1.809 vs Caucasian patients, P < 0.001), transferred patients(OR = 1.347 vs non-transferred, P < 0.001), emergency admissions(OR = 3.032 vs elective cases, P < 0.001), patients in the Northeast region(OR = 1.449 vs West, P < 0.001) had significantly higher odds of inhospital mortality. Number of diagnoses and number of procedures showed positive correlations with in-hospital death(OR = 1.249 per one increase in number of procedures). Patients diagnosed with acute respiratory failure(OR = 8.246), acute kidney failure(OR = 4.359), hepatic encephalopathy(OR = 2.217) and esophageal variceal bleeding(OR = 2.187) were at considerably higher odds of in-hospital death compared with ascites(OR = 0.136, P < 0.001). Comorbidity measures with the highest odds of in-hospital death were fluid and electrolyte disorders(OR = 2.823), coagulopathy(OR = 2.016), and lymphoma(OR = 1.842).CONCLUSION: The overall mortality of the TIPS procedure is steadily decreasing, though the length of stay has remained relatively constant. Specific patient ethnicity, location, transfer status, primary diagnosis and comorbidities correlate with increased odds of TIPS in-hospital death.Edward Wolfgang Lee Andrew Kuei Sammy Saab Ronald W Busuttil Francisco Durazo Steven-Huy Han Mohamed M El-Kabany Justin P Mc Williams Stephen T Kee 2016World Journal of Gastroenterology2016,22,25:7
17Multiple Antibiotic Resistance and Heavy Metal Resistance Profile of Bacteria Isolated from Giant Freshwater Prawn (Macrobrachium rosenbergii) Hatchery显示文摘In this article, antibiogram and heavy metal resistance profile of bacteria isolated from giant freshwater prawn (Macrobrachium rosenbergii) hatchery in Malaysia are described. Although giant freshwater prawn was introduced into Malaysia since the 1980s, there was no database information on antibiogram and heavy metal resistance profile of bacteria from giant freshwater prawn (M. rosenbergii) hatchery in Malaysia. Therefore, this study was carried out to determine the effectiveness of antibiotic and heavy metal resistance profile to control bacterial diseases in M. rosenbergii hatchery. The results can provide valuable information for local M. rosenbergii post-larval producer. Antibiotic sensitivity test was carried out by disk-diffusion method against 15 types of antibiotics as follows: oxolinic acid (2 μg), ampicillin (10 μg), erythromycin (15 μg), furazolidone (15 μg), lincomycin (15 μg), amoxicillin (25 μg), colistin sulphate (25 μg), doxycycline (30 μg), florfenicol (30 μg), flumequine (30 μg), nalidixic acid (30 μg), tetracycline (30 μg), oleandomycin (15 μg), fosfomycin (50 μg), and spiramycin (100 μg), whereas heavy metal resistance profile of the present bacterial isolates was determined by 2-fold agar dilution technique. In this study, 5 types of bacteria were successfully isolated; they were Aeromonas spp. (n = 77), Escherichia coli (n = 73), Edwardsiella spp. (n = 62), Salmonella spp. (n = 75), and Vibrio spp. (n = 43). The result showed that furazolidone was the most effective antibiotic to control the bacteria isolated in this study, approximately 89.7% of the bacterial isolates were sensitive to this antibiotic. Multiple antibiotic resistance (MAR) index indicated that the hatchery water source and M. rosenbergii post-larval and sediment tanks were at high-risk exposure to the tested antibiotic. Furthermore, all the tested heavy metals (Cd2+, Cr6+, Hg2+, and Cu2+) failed to inhibit the growth of the bacterial isolates. Therefore, it indicated that the water source of the hatchery is contaminated with both antibiotic residues and heavy metal.S W Lee M Najiah W Wendy A Zahrol M Nadirah 2009Agricultural Sciences in China2009,8,6:7

19Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed.Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee 2014World Journal of Clinical Oncology2014,5,2:5
20Global hypomethylation in hepatocellular carcinoma and its relationship to aflatoxin B_1 exposure显示文摘AIM:To determine global DNA methylation in paired hepatocellular carcinoma(HCC) samples using several different assays and explore the correlations between hypomethylation and clinical parameters and biomarkers,including that of aflatoxin B 1 exposure.METHODS:Using the radio labeled methyl acceptance assay as a measure of global hypomethylation,as well as two repetitive elements,including satellite 2(Sat2) by MethyLight and long interspersed nucleotide elements(LINE1),by pyrosequencing.RESULTS:By all three assays,mean methylation levels in tumor tissues were significantly lower than that in adjacent tissues.Methyl acceptance assay log(mean ± SD) disintegrations/min/ng DNA are 70.0 ± 54.8 and 32.4 ± 15.6,respectively,P = 0.040;percent methylation of Sat2 42.2 ± 55.1 and 117.9 ± 88.8,respectively,P < 0.0001 and percent methylation LINE1 48.6 ± 14.8 and 71.7 ± 1.4,respectively,P < 0.0001.Aflatoxin B 1 albumin(AFB 1-Alb) adducts,a measure of exposure to this dietary carcinogen,were inversely correlated with LINE1 methylation(r =-0.36,P = 0.034).CONCLUSION:Consistent hypomethylation in tumor compared to adjacent tissue was found by the three different methods.AFB 1 exposure is associated with DNA global hypomethylation,suggesting that chemical carcinogens may influence epigenetic changes in humans.Hulya Yazici Ming-Whei Yu Po-Huang Lee Regina M Santella 2012World Journal of Hepatology2012,4,5:5
