| 1 | Comparative review of vertebroplasty and kyphoplasty显示文摘The aim of this review is to compare the effectiveness of percutaneous vertebroplasty and kyphoplasty to treat pain and improve functional outcome from ver-tebral fractures secondary to osteoporosis and tumor conditions. In 2009, two open randomized controlled trials published in the New England Journal of Medicine questioned the value of vertebroplasty in treating ver-tebral compression fractures. Nevertheless, the prac-tice of physicians treating these conditions has barely changed. The objective of this review is to try to clarify the most important issues, based on our own experi-ence and the reported evidence about both techniques, and to guide towards the most appropriate choice of treatment of vertebral fractures, although many ques-tions still remain unanswered. | Ferno Ruiz Santiago Alicia Santiago Chinchilla Luis Guzmán álvarez Antonio Luis Pérez Abela Maria del Mar Castellano García Miguel Pajares López | 2014 | World Journal of Radiology2014，6，6： | 30 |

| 3 | Risk factors associated with the development of ischemic colitis显示文摘AIM:To ascertain the role of cardiovascular risk factors,cardiovascular diseases,standard treatments and other diseases in the development of ischemic colitis(IC).METHODS:A retrospective,case-control study was designed,using matched data and covering 161 incident cases of IC who required admission to our hospital from 1998 through 2003.IC was diagnosed on the basis of endoscopic findings and diagnostic or compatible his-tology.Controls were randomly chosen from a cohort of patients who were admitted in the same period and required a colonoscopy,excluding those with diagnosis of colitis.Cases were matched with controls(ratio 1:2),by age and sex.A conditional logistic regression was performed.RESULTS:A total of 483 patients(161 cases,322 con-trols)were included;mean age 75.67±10.03 years,55.9%women.The principal indications for colonos-copy in the control group were lower gastrointestinal hemorrhage(35.4%),anemia(33.9%),abdominal pain(19.9%)and diarrhea(9.6%).The endoscopic findings in this group were hemorrhoids(25.5%),diverticular disease(30.4%),polyps(19.9%)and colorectal cancer(10.2%).The following variables were associated with IC in the univariate analysis:arterial hypertension(P= 0.033);dyslipidemia(P<0.001);diabetes mellitus(P =0.025);peripheral arterial disease(P=0.004);heart failure(P=0.026);treatment with hypotensive drugs(P=0.023);angiotensin-converting enzyme inhibitors;(P=0.018);calcium channel antagonists(P=0.028);and acetylsalicylic acid(ASA)(P<0.001).Finally,the following variables were independently associated with the development of IC:diabetes mellitus[odds ratio(OR)1.76,95%confidence interval(CI):1.001-3.077,P=0.046];dyslipidemia(OR 2.12,95%CI:1.26-3.57,P=0.004);heart failure(OR 3.17,95%CI:1.31-7.68,P=0.01);peripheral arterial disease(OR 4.1,95%CI:1.32-12.72,P=0.015);treatment with digoxin(digitalis)(OR 0.27,95%CI:0.084-0.857,P=0.026);and ASA(OR 1.97,95%CI:1.16-3.36,P=0.012).CONCLUSION:The development of an episode of IC was independently associated with diabetes,dyslipid-emia,presence of heart failure,peripheral arterial dis-ease and treatment with digoxin or ASA. | Joaquín Cubiella Fernández Luisa Núez Calvo Elvira González Vázquez Maria Jesús García García Maria Teresa Alves Pérez Isabel Martínez Silva Javier Fernández Seara | 2010 | World Journal of Gastroenterology2010，16，36： | 27 |
| 4 | History of the infantile hepatic hemangioma:From imaging to generating a differential diagnosis显示文摘We aim to provide an up-to-date summary of infantile hepatic hemangioma(IHH) and its misnomers and to dialectically present the differential diagnosis of these rare entities of the liver.Eligible peer-reviewed articles on hepatic infantile hemangiomas,published between 2000 and 2015,were reviewed for this study.IHH is the most common hepatic vascular tumor in children.Once a liver mass is identified in an infant,the differential diagnosis ranges from vascular malformations to benign and malignant tumors including mesenchymal hamartoma,hepatoblastoma,metastatic neuroblastoma,so careful physical examination,imaging studies,and,if indicated,tumor markers and biopsy,are of pivotal importance to ascertain the correct diagnosis.Despite the benign nature of IHHs,some of these lesions may demand medical and/or surgical intervention,especially for multiple and diffuse IHH.Complications can include hepatomegaly,hypothyroidism and cardiac failure.Therefore,a close follow-up is required until complete involution of the lesions.We propose an algorithm to guide the physicians towards the proper management of hepatic lesions. | Maria Gnarra Gerald Behr Alison Kitajewski June K Wu Sudha A Anupindi Carrie J Shawber Nick Zavras Dimitrios Schizas Chris Salakos Konstantinos P Economopoulos | 2016 | World Journal of Clinical Pediatrics2016，5，3： | 27 |
| 5 | Multiplex RT-PCR-based detections of CEA, CK20 and EGFR in colorectal cancer patients显示文摘AIM: To develop a multiplex reverse transcription polymerase chain reaction (RT-PCR) method detecting cir-culating tumor cells in the peripheral blood of colorectal cancer (CRC) patients. METHODS: Peripheral blood samples were collected from 88 CRC patients and 40 healthy individuals from the blood donors' clinic and subsequently analyzed by multiplex RT-RCR for the expression of carcinoembryonic antigen (CEA), cytokeratin 20 (CK20) and epidermal growth factor receptor (EGFR) mRNA. The analysis involved determining the detection rates of CEA, CK20 and EGFR transcripts vs disease stage and overall survival. Median follow-up period was 19 mo (range 8-28 mo). RESULTS: Rates of CEA, CK20 and EGFR detection in CRC patients were 95.5%, 78.4% and 19.3%, respectively. CEA transcripts were detected in 3 healthy volunteer samples (7.5%), whereas all control samples were tested negative for CK20 and EGFR transcripts. The increasing number of positive detections for CEA, CK20 and EGFR transcripts in each blood sample was positively correlated with Astler-Coller disease stage (P< 0.001) and preoperative serum levels of CEA (P=0.029) in CRC patients. Data analysis using Kaplan-Meier estimator documented signif icant differences in the overall survival of the different CRC patient groups as formed according to the increasing number of positivity for CEA, CK20 and EGFR transcripts. CONCLUSION: These data suggest that multiplex RTPCR assay can provide useful information concerning disease stage and overall survival of CRC patients. | Aikaterini Tsouma Chrysanthi Aggeli Panagiotis Lembessis George N Zografos Dimitris P Korkolis Dimitrios Pectasides Maria Skondra Nikolaos Pissimissis Anastasia Tzonou Michael Koutsilieris | 2010 | World Journal of Gastroenterology2010，16，47： | 19 |
| 6 | Hepatitis B and inflammatory bowel disease: Role of antiviral prophylaxis显示文摘Hepatitis B virus (HBV) is a very common infection worldwide. Its reactivation in patients receiving immunosuppression has been widely described as being associated with significant morbidity and mortality unless anti-viral prophylaxis is administered. Treatment in inflammatory bowel disease (IBD) patients has changed in recent years and immunosuppression and biological therapies are now used more frequently than before. Although current studies have reported an incidence of hepatitis B in inflammatory bowel disease patients similar to that in the general population, associated liver damage remains an important concern in this setting. Liver dysfunction may manifest in several ways, from a subtle change in serum aminotransferase levels to fulminant liver failure and death. Patients undergoing double immunosuppression are at a higher risk, and reactivation usually occurs after more than one year of treatment. As preventive measures, all IBD patients should be screened for HBV markers at diagnosis and those who are positive for the hepatitis B surface antigen should receive antiviral prophylaxis before undergoing immunosuppression in order to avoid HBV reactivation. Tenofovir/entecavir are preferred to lamivudine as nucleos(t)ide analogues due to their better resistance profile. In patients with occult or resolved HBV, viral reactivation does not appear to be a relevant issue and regular DNA determination is recommended during immunosuppression therapy. Consensus guidelines on this topic have been published in recent years. The prevention and management of HBV infection in IBD patients is addressed in this review in order to address practical | Pilar López-Serrano Jose Lázaro Pérez-Calle Maria Dolores Sánchez-Tembleque | 2013 | World Journal of Gastroenterology2013，19，9： | 12 |
| 7 | Helicobacter pylori and autoimmune disease:Cause or bystander显示文摘Helicobacter pylori(H.pylori)is the main cause of chronic gastritis and a major risk factor for gastric cancer.This pathogen has also been considered a potential trigger of gastric autoimmunity,and in particular of autoimmune gastritis.However,a considerable number of reports have attempted to link H.pylori infection with the development of extra-gastrointestinal autoimmune disorders,affecting organs not immediately relevant to the stomach.This review discusses the current evidence in support or against the role of H.pylori as a potential trigger of autoimmune rheumatic and skin diseases,as well as organ specific autoimmune diseases.We discuss epidemiological,serological,immunological and experimental evidence associating this pathogen with autoimmune diseases.Although over one hundred autoimmune diseases have been investigated in relation to H.pylori,we discuss a select number of papers with a larger literature base,and include Sj grens syndrome,rheumatoid arthritis,systemic lupus erythematosus,vasculitides,autoimmune skin conditions,idiopathic thrombocytopenic purpura,autoimmune thyroid disease,multiple sclerosis,neuromyelitis optica and autoimmune liver diseases.Specific mention is given to those studies reporting an association of anti-H.pylori antibodies with the presence of autoimmune disease-specific clinical parameters,as well as those failing to find such associations.We also provide helpful hints for future research. | Daniel S Smyk Andreas L Koutsoumpas Maria G Myt-ilinaiou Eirini I Rigopoulou Lazaros I Sakkas Dimitrios P Bogdanos | 2014 | World Journal of Gastroenterology2014，20，3： | 12 |
| 8 | Single nucleotide polymorphisms of OCTN1, OCTN2, and DLG5 genes in Greek patients with Crohn's disease显示文摘AIM: To validate novel single nucleotide polymorphisms (SNPs) in Greek patients with Crohn's disease (CD).METHODS: A total of 120 patients with CD, 85 patients with UC, and 100 unrelated healthy controls were genotyped. Genotyping was performed by allele-specific PCR or by PCR-RFLP analysis.RESULTS: Our results showed that the 1672T and -207C alleles were obviously over-represented in CD patients only (P<0.01 and P<0.05, respectively) compared to the control population. The G113A polymorphism was completely absent in our studied population. The odds ratio for the carriage of the TC haplotype was 2.21 for CD patients as compared with controls. Additionally, the frequency of the TC haplotype was increased in patients with ileocolitis or colitis, and was mainly associated with the fibrostenotic phenotype of the disease. Furthermore, when the TC haplotype was compared jointly with the carriage of at least one mutation of the NOD2/CARD15 gene, there was an increased risk for CD, but not for UC, compared to controls. Regarding the location of the disease, the concomitant presence of the TC haplotype and NOD2/CARD15 mutations was mainly associated with ileocolitis or ileitis. CONCLUSION: Collectively, our results suggest that the 1672T variant of the OCTN1 gene and the -207C variant of the OCTN2 gene represent risk factors for CD in the Greek population. | Maria Gazouli Gerassimos Mantzaris Athanassios J Archimandritis George Nasioulas Nicholas P Anagnou | 2005 | World Journal of Gastroenterology2005，11，47： | 12 |
| 9 | Adsorption of Mn^(2+) from aqueous solution using Fe and Mn oxide-coated sand显示文摘The adsorption of Mn2+ onto immobilized Mn-oxide and Fe-oxide adsorbent such as manganese oxide-coated sand 1 (MOCS1), manganese oxide-coated sand2 (MOCS2), iron oxide-coated sand2 (IOCS2), and manganese and iron oxide-coated sand (MIOCS)was investigated. The effects of pH (5.5 to 8.0) and temperature (25 to45°C) on the equilibrium capacitywere examined. Equilibrium studies showed that there is a good fitwith both Freundlich and Langmuir isotherm,which indicates surface heterogeneity and monolayer adsorption of the adsorbents. Kineticdata showed high correlationwith the pseudo second-order model,which signifies a chemisorption-controlled mechanism. The activation energies, activation parameters (ΔG*,ΔH*,ΔS*), and thermodynamic parameters (ΔG0 , ΔH0 , ΔS0 ) confirmed that adsorptionwith MIOCSwas endothermic and more spontaneous at higher temperaturewhile an opposite trendwas observed for the other adsorbents. Thermodynamic studies showed that adsorption involved formation of activated complex,where MOCS1 and MIOCS follow a physical-chemical mechanism,while MOCS2 and IOCS2 follows purely chemical mechanism. | Chi-Chuan Kan Mannie C Aganon Cybelle Morales Futalan Maria Lourdes P Dalida | 2013 | Journal of Environmental Sciences2013，25，7： | 11 |
| 10 | Liver histology in ICU patients dying from sepsis:A clinico-pathological study显示文摘AIM:To determine end-stage pathologic changes in the liver of septic patients dying in the intensive care unit. METHODS: Needle liver biopsies obtained immediately after death from 15 consecutive patients with sepsis and no underlying liver disease were subjected to routine histological examination. Liver function tests and clinical monitoring measurements were also recorded. RESULTS: Liver biochemistries were increased in the majority of patients before death. Histology of liver bi- opsy specimens showed portal inflammation in 73.3%, centrilobular necrosis in 80%, lobular inflammation in 66.7%, hepatocellular apoptosis in 66.6% and cholan- gitis/cholangiolitis in 20% of patients. Mixed hepatitic/ cholestatic type of liver injury was observed in 6/15 (40%) patients and hepatitc in 9/15 (60%). Steatosis was ob- served in 11/15 (73.3%) patients affecting 5%-80% of liver parenchyma. Among the histological features, the presence of portal inflammation in liver biopsy was as- sociated with increased hospitalization in the ICU prior death (P = 0.026). CONCLUSION: Features of hepatitis and steatosis arethe main histological findings in the liver in the majority of patients dying from sepsis. | John Koskinas Ilias P Gomatos Dina G Tiniakos Nikolaos Memos Maria Boutsikou Aspasia Garatzioti Athanasios Archimandritis Alexander Betrosian | 2008 | World Journal of Gastroenterology2008，14，9： | 8 |
| 11 | Is autoimmune hepatitis a frequent finding among HCV patients with intense interface hepatitis?显示文摘AIM:To evaluate the overlap of autoimmune hepatitis in hepatitis C virus(HCV)-infected patients with intense interface hepatitis.METHODS:Among 1759 patients with hepatitis C submitted to liver biopsy,92(5.2%) presented intense interface hepatitis.These patients were evaluated regarding the presence of antinuclear antibody(ANA),anti-smooth muscle antibody(SMA) and anti-liver/kidney microsomal antibody(LKM-1),levels of γ-globulin and histological findings related to autoimmune hepatitis(plasma cell infiltrate and presence of rosettes).RESULTS:Among patients with hepatitis C and intense interface hepatitis there was a low prevalence of autoantibodies(ANA=12%,SMA=5%,LKM-1=0%) and the median γ-globulin level was within the normal range.Typical histological findings of autoimmune disease were observed in only two cases(2%).After applying the score for diagnosis of autoimmune hepatitis,only one patient was classified with a definitive diagnosis of autoimmune hepatitis.Since overlap with autoimmune hepatitis was not the explanation for the intense necroinflammatory activity in patients with chronic hepatitis C we sought to identify the variables associated with this finding.The presence of intense interface hepatitis was associated with more advanced age,both at the time of infection and at the time of the biopsy,and higher prevalence of blood transfusion and alcohol abuse.CONCLUSION:Although possible,overlap with autoimmune hepatitis is a very rare association in HCV-infected patients with intense interface hepatitis,an unusual presentation which seems to be related to other host variables. | Rosilene G Badiani Vitória Becker Renata M Perez Carla AL Matos Lara B Lemos Valéria P Lanzoni Luis Eduardo C Andrade Alessandra Dellavance Antonio Eduardo B Silva Maria Lucia G Ferraz | 2010 | World Journal of Gastroenterology2010，16，29： | 7 |
| 12 | NOD2/CARD15 , ATG16L1 and IL23R gene polymorphisms and childhood-onset of Crohn’s disease显示文摘AIM: To assess whether the polymorphisms of NOD2/ CARD15 , autophagy-related 16-like 1 (ATG16L1 ), and interleukin-23 receptor (IL23R ) genes play a more critical role in the susceptibility of childhood-onset than in adult-onset Crohn’s disease (CD). METHODS: Polymorphisms R702W, G908R, and 3020insC of NOD2/CARD15 ; rs2241880 A/G of ATG16L1 , and rs11209026 (R381Q) of IL23R gene were assessed in 110 childhood-onset CD, 364 adult-onset CD, and 539 healthy individuals. Analysis of polymorphisms R702W, G908R, and 3020insC of NOD2/CARD15 genotyping was performed by allele specific polymerase chain reaction (PCR) or by PCR-restriction fragment length polymor-phism analysis. The polymorphisms rs2241880 A/G of the ATG16L1 , and rs11209026 (R381Q) of the IL23R gene in the children’s cohort were genotyped by PCR and melting curve analysis whereas adult group genotyping was performed using the Affymetrix Genome-Wide Human SNP Array 5.0 (500K). RESULTS: The 3020insC allele in NOD2/CARD15 was significantly higher in childhood than in adult-onset CD (P = 0.0067). Association with at least 1 NOD2/CARD15 variant was specific for ileal disease (with or without co- lonic involvement). Even if the frequency of G allele of the rs2241880 ATG16L1 polymorphism was increased in both paediatric and adult CD patients compared to con- trols (P = 0.017 and P = 0.001, respectively), no difference was observed between the childhood and the adult cohort. The rare Q allele of IL23R rs11209026 polymorphism was underrepresented in both paediatric and adult CD cases (P = 0.0018 and P = 0.04, respectively) and no difference was observed between the childhood and the adult cohort. The presence of the rs2241880 ATG16L1 and rs11209026 IL23R polymorphisms did not influence disease phenotype. CONCLUSION: Polymorphism 3020insC in NOD2/ CARD15 occurs statistically significantly more often in patients with childhood-onset CD than in patients with adult-onset CD. The ATG16L1 and IL23R variants are associated with susceptibility to CD, but not earlyonset disease. | Maria Gazouli Ioanna Pachoula Ioanna Panayotou Gerassimos Mantzaris George Chrousos Nicholas P Anagnou Eleftheria Roma-Giannikou | 2010 | World Journal of Gastroenterology2010，16，14： | 7 |
| 13 | Computed tomography and patient risk:Facts,perceptions and uncertainties显示文摘Since its introduction in the 1970s, computed tomography(CT) has revolutionized diagnostic decision-making. One of the major concerns associated with the widespread use of CT is the associated increased radiation exposure incurred by patients. The link between ionizing radiation and the subsequent development of neoplasia has been largely based on extrapolating data from studies of survivors of the atomic bombs dropped in Japan in 1945 and on assessments of the increased relative risk of neoplasia in those occupationally exposed to radiation within the nuclear industry. However, the association between exposure to low-dose radiation from diagnostic imaging examinations and oncogenesis remains unclear. With improved technology, significant advances have already been achieved with regards to radiation dose reduction. There are several dose optimization strategies available that may be readily employed including omitting unnecessary images at the ends of acquired series, minimizing the number of phases acquired, and the use of automated exposure control as opposed to fixed tube current techniques. In addition, new image reconstruction techniques that reduce radiation dose have been developed in recent years with promising results. These techniques use iterative reconstruction algorithms to attain diagnostic quality images with reduced image noise at lower radiation doses. | Stephen P Power Fiachra Moloney Maria Twomey Karl James Owen J O'Connor Michael M Maher | 2016 | World Journal of Radiology2016，8，12： | 7 |
| 14 | Role of tissue microenvironment resident adipocytes in colon cancer显示文摘Colorectal cancer(CRC) is a multifactorial disease characterized by several genetic and epigenetic alterations occurring in epithelial cells. It is increasingly recognized that tumour progression is also regulated by tumour microenvironment(TME). The bidirectional cross-talk between tumour resident adipocytes and cancer cells within TME has been proposed as active contributor to carcinogenesis. Tumour resident adipocytes exhibit an activated phenotype characterized by increased secretion of pro-tumorigenic factors(angiogenic/inflammatory/immune) which contribute to cancer cell proliferation, invasion, neoangiogenesis, evasion of immune surveillance and therapy resistance. Furthermore, adipocytes represent a fuel rich source for increasing energy demand of rapidly proliferating tumour cells. Interestingly, a relationship between obesity and molecular variants in CRC has recently been identified. Whether adipose tissue promotes cancer progression in subsets of molecular phenotypes or whether local tissue adipocytes are involved in inactivation of tumour suppressor genes and/or activation of oncogenes still needs to be explored. This editorial highlights the major findings related to crosstalk between adipocytes and colon cancer cells and how local paracrine interactions may promote cancer progression. Furthermore, we provide future strategies in studying colonic TME which could provide insights in bidirectional cross-talk mechanisms between adipocytes and colonic epithelial cells. This could enable to decipher critical signalling pathways of both early colonic carcinogenesis and cancer progression. | Maria Tabuso Shervanthi Homer-Vanniasinkam Raghu Adya Ramesh P Arasaradnam | 2017 | World Journal of Gastroenterology2017，23，32： | 6 |
| 15 | Timely reperfusion for ST-segment elevation myocardial infarction:Effect of direct transfer to primary angioplasty on time delays and clinical outcomes显示文摘Primary percutaneous coronary intervention(PPCI) is the preferred reperfusion therapy for patients presenting with ST-segment elevation myocardial infarction(STEMI) when it can be performed expeditiously and by experienced operators. In spite of excellent clinical results this technique is associated with longer delays than thrombolysis and this fact may nullify the benefit of selecting this therapeutic option. Several strategies have been proposed to decrease the temporal delays to deliver PPCI. Among them,prehospital diagnosis and direct transfer to the cath lab,by-passing the emergency department of hospitals,has emerged as anattractive way of diminishing delays. The purpose of this review is to address the effect of direct transfer on time delays and clinical events of patients with STEMI treated by PPCI. | Rodrigo Estévez-Loureiro ángela López-Sainz Armo Pérez de Prado Carlos Cuellas Ramón Calvio Santos Norberto Alonso-Orcajo Jorge Salgado Fernández Jose Manuel Vázquez-Rodríguez Maria López-Benito Felipe Fernández-Vázquez | 2014 | World Journal of Cardiology2014，6，6： | 6 |
| 16 | Development of a quantum-dot-labelled magnetic immunoassay method for circulating colorectal cancer cell detection显示文摘AIM:To detect of colorectal cancer(CRC) circulating tumour cells(CTCs) surface antigens,we present an assay incorporating cadmium selenide quantum dots(QDs) in these paper.METHODS:The principle of the assay is the immunomagnetic separation of CTCs from body fluids in conjunction with QDs,using specific antibody biomarkers:epithelial cell adhesion molecule antibody,and monoclonal cytokeratin 19 antibody.The detection signal was acquired from the fluorescence signal of QDs.For the evaluation of the performance,the method under study was used to isolate the human colon adenocarcinoma cell line(DLD-1) and CTCs from CRC patients' peripheral blood.RESULTS:The minimum detection limit of the assay was defined to 10 DLD-1 CRC cells/mL as fluorescence was measured with a spectrofluorometer.Fluorescenceactivated cell sorting analysis and Real Time RT-PCR,they both have also been used to evaluate the performance of the described method.In conclusion,we developed a simple,sensitive,efficient and of lower cost(than the existing ones) method for the detection of CRC CTCs in human samples.We have accomplished these results by using magnetic bead isolation and subsequent QD fluorescence detection.CONCLUSION:The method described here can be easily adjusted for any other protein target of either the CTC or the host. | Maria Gazouli Anna Lyberopoulou Pericles Pericleous Spyros Rizos Gerassimos Aravantinos Nikolaos Nikiteas Nicholas P Anagnou Efstathios P Efstathopoulos | 2012 | World Journal of Gastroenterology2012，18，32： | 6 |
| 17 | Short and long term fate of human AMSC subcutaneously injected in mice显示文摘AIM:To study the ability of human adipose-derived mesenchymal stem cells(AMSCs)to survive over the short and long term,their biodistribution and their biosafety in vivo in tumor-prone environments.METHODS:We subcutaneously injected human AMSCs from different human donors into immunodeficient SCID mice over both short-(2 and 4 mo)and long-(17 mo)term in young,and aged tumor-prone mice.Presence of human cells was studied by immunohistochemistry and polymerase chain reaction analysis in all organs of injected mice.RESULTS:Subcutaneously injected AMSCs did not form teratomas at any time point.They did not migrate but remained at the site of injection regardless of animal age,and did not fuse with host cells in any organ examined.AMSCs survived in vivo for at least 17 mo after injection,and differentiated into fibroblasts of the subdermic connective tissue and into mature adipocytes of fat tissue,exclusively at the site of injection.CONCLUSION:Our results support the assertion that AMSC may be safe candidates for therapy when injected subcutaneously because of their long term inability to form teratomas. | Pilar López-Iglesias Alejandro Blázquez-Martínez Jorge Fernández-Delgado Javier Regadera Manuel Nistal Maria P De Miguel | 2011 | World Journal of Stem Cells2011，3，6： | 5 |
| 18 | Metabolic and hepatic effects of liraglutide,obeticholic acid and elafibranor in diet-induced obese mouse models of biopsy-confirmed nonalcoholic steatohepatitis显示文摘AIM To evaluate the pharmacodynamics of compounds in clinical development for nonalcoholic steatohepatitis(NASH) in obese mouse models of biopsy-confirmedNASH.METHODS Male wild-type C57 BL/6 J mice(DIO-NASH) and Lep^(ob/ob)(ob/ob-NASH) mice were fed a diet high in trans-fat(40%), fructose(20%) and cholesterol(2%) for 30 and 21 wk, respectively. Prior to treatment, all mice underwent liver biopsy for confirmation and stratification of liver steatosis and fibrosis, using the nonalcoholic fatty liver disease activity score(NAS) and fibrosis staging system. The mice were kept on the diet and received vehicle, liraglutide(0.2 mg/kg, SC, BID), obeticholic acid(OCA, 30 mg/kg PO, QD), or elafibranor(30 mg/kg PO, QD) for eight weeks. Within-subject comparisons were performed on changes in steatosis, inflammation, ballooning degeneration, and fibrosis scores. In addition, compound effects were evaluated by quantitative liver histology, including percent fractional area of liver fat, galectin-3, and collagen 1 a1.RESULTS Liraglutide and elafibranor, but not OCA, reduced body weight in both models. Liraglutide improved steatosis scores in DIO-NASH mice only. Elafibranor and OCA reduced histopathological scores of hepatic steatosis and inflammation in both models, but only elafibranor reduced fibrosis severity. Liraglutide and OCA reduced total liver fat, collagen 1 a1, and galectin-3 content, driven by significant reductions in liver weight. The individual drug effects on NASH histological endpoints were supported by global gene expression(RNA sequencing) and liver lipid biochemistry.CONCLUSION DIO-NASH and ob/ob-NASH mouse models show distinct treatment effects of liraglutide, OCA, and elafibranor, being in general agreement with corresponding findings in clinical trials for NASH. The present data therefore further supports the clinical translatability and utility of DIO-NASH and ob/ob-NASH mouse models of NASH for probing the therapeutic efficacy of compounds in preclinical drug development for NASH. | Kirstine S Tolbol Maria NB Kristiansen Henrik H Hansen Sanne S Veidal Kristoffer TG Rigbolt Matthew P Gillum Jacob Jelsing Niels Vrang Michael Feigh | 2018 | World Journal of Gastroenterology2018，24，2： | 5 |
| 19 | Presacral venous bleeding during mobilization in rectal cancer显示文摘AIM To analyze the anatomy of sacral venous plexus flow, the causes of injuries and the methods for controlling presacral hemorrhage during surgery for rectal cancer.METHODS A review of the databases MEDLINE? and Embase? was conducted, and relevant scientific articles published between January 1960 and June 2016 were examined. The anatomy of the sacrum and its venous plexus, as well as the factors that influence bleeding, the causes of this complication, and its surgical management were defined.RESULTS This is a review of 58 published articles on presacral venous plexus injury during the mobilization of the rectum and on techniques used to treat presacral venous bleeding. Due to the lack of cases published in the literature, there is no consensus on which is the best technique to use if there is presacral bleeding during mobilization in surgery for rectal cancer. This review may provide a tool to help surgeons make decisions regarding how to resolve this serious complication.CONCLUSION A series of alternative treatments are described; however, a conventional systematic review in which optimal treatment is identified could not be performed because few cases were analyzed in most publications. | Jose Enrique Casal Núnez Vincenzo Vigorita Alejandro Ruano Poblador Ana María Gay Fernández Maria ángeles Toscano Novella Nieves Cáceres Alvarado Lucinda Pérez Dominguez | 2017 | World Journal of Gastroenterology2017，23，9： | 4 |
