| 1 | Clinical value of rapid urine trypsinogen-2 test strip, urinary trypsinogen activation peptide, and serum and urinary activation peptide of carboxypeptidase B in acute pancreatitis显示文摘AIM: To assess the usefulness of urinary trypsinogen-2 test strip, urinary trypsinogen activation peptide (TAP),and serum and urine concentrations of the activation peptide of carboxypeptidase B (CAPAP) in the diagnosisof acute pancreatitis.METHODS: Patients with acute abdominal pain and hospitalized within 24 h after the onset of symptoms were prospectively studied. Urinary trypsinogen-2 was considered positive when a clear blue line was observed (detection limit 50 μg/L). Urinary TAP was measured using a quantitative solid-phase ELISA, and serum and urinary CAPAP by a radioimmunoassay method.RESULTS: Acute abdominal pain was due to acute pancreatitis in 50 patients and turned out to be extrapancreatic in origin in 22 patients. Patients with acute pancreatitis showed significantly higher median levels of serum and urinary CAPAP levels, as well as amylase and lipase than extrapancreatic controls. Median TAP levels were similar in both groups. The urinary trypsinogen-2 test strip was positive in 68% of patients with acute pancreatitis and 13.6% in extrapancreatic controls (P<0.01). Urinary CAPAP was the most reliable test for the diagnosis of acute pancreatitis (sensitivity 66.7%, specificity 95.5%, positive and negative predictive values 96.6% and 56.7%, respectively), with a 14.6 positive likelihood ratio for a cut-off value of 2.32 nmol/L.CONCLUSION: In patients with acute abdominal pain,hospitalized within 24 h of symptom onset, CAPAP in serum and urine was a reliable diagnostic marker of acute pancreatitis. Urinary trypsinogen-2 test strip showed a clinical value similar to amylase and lipase.Urinary TAP was not a useful screening test for the diagnosis of acute pancreatitis. | Jesús Sáez Juan Martínez Celia Trigo José Sánchez-Payá Luis Compay Raquel Laveda Pilar Grió Cristina García Miguel Pérez-Mateo | 2005 | World Journal of Gastroenterology2005，11，46： | 21 |
| 2 | Influence of gut microbiota on neuropsychiatric disorders显示文摘The last decade has witnessed a growing appreciation of the fundamental role played by an early assembly of a diverse and balanced gut microbiota and its subsequent maintenance for future health of the host. Gut microbiota is currently viewed as a key regulator of a fluent bidirectional dialogue between the gut and the brain(gut-brain axis). A number of preclinical studies have suggested that the microbiota and its genome(microbiome) may play a key role in neurodevelopmental and neurodegenerative disorders. Furthermore, alterations in the gut microbiota composition in humans have also been linked to a variety of neuropsychiatric conditions, including depression, autism and Parkinson's disease. However, it is not yet clear whether these changes in the microbiome are causally related to such diseases or are secondary effects thereof. In this respect, recent studies in animals have indicated that gut microbiota transplantation can transfer a behavioral phenotype, suggesting that the gut microbiota may be a modifiable factor modulating the development or pathogenesis of neuropsychiatric conditions. Further studies are warranted to establish whether or not the findings of preclinical animal experiments can be generalized to humans. Moreover, although different communication routes between the microbiota and brain have been identified, further studies must elucidate all the underlying mechanisms involved. Such research is expected to contribute to the design of strategies to modulate the gut microbiota and its functions with a view to improving mental health, and thus provide opportunities to improve the management of psychiatric diseases. Here, we review the evidence supporting a role of the gut microbiota in neuropsychiatric disorders and the state of the art regarding the mechanisms underlying its contribution to mental illness and health. We also consider the stages of life where the gut microbiota is more susceptible to the effects of environmental stressors, and the possible microbiota-targeted intervention strategies that could improve health status and prevent psychiatric disorders in the near future. | María Carmen Cenit Yolanda Sanz Pilar Codoner-Franch | 2017 | World Journal of Gastroenterology2017，23，30： | 21 |
| 3 | The Immune System and the Role of Inflammation in Perinatal Depression显示文摘Major depression during pregnancy is a common psychiatric disorder that arises from a complex and multifactorial etiology. Psychosocial stress, sex, hormones, and genetic vulnerability increase the risk for triggering mood disorders. Microglia and toll-like receptor 4 play a crucial role in triggering wide and varied stress-induced responses mediated through activation of the inflammasome; this leads to the secretion of inflammatory cytokines, increased serotonin metabolism, and reduction of neurotransmitter availability along with hypothalamic–pituitary–adrenal axis hyperactivity. Dysregulation of this intricate neuroimmune communication network during pregnancy modifies the maternal milieu, enhancing the emergence of depressive symptoms and negative obstetric and neuropsychiatric outcomes. Although several studies have clearly demonstrated the role of the innate immune system in major depression, it is still unclear how the placenta, the brain, and the monoaminergic and neuroendocrine systems interact during perinatal depression. Thus, in the present review we describe the cellular and molecular interactions between these systems in major depression during pregnancy, proposing that the same stress-related mechanisms involved in the activation of the NLRP3 inflammasome in microglia and peripheral myeloid cells in depressed patients operate in a similar fashion in the neuroimmune placenta during perinatal depression. Thus, activation of Toll-like receptor 2 and 4 signaling and the NLRP3 inflammasome in placental immune cells may promote a shift of the Th1/Th2 bias towards a predominant Th1/Th17 inflammatory response, associated with increased secretion of pro-inflammatory cytokines, among other secreted autocrine and paracrine mediators, which play a crucial role in triggering and/or exacerbating depressive symptoms during pregnancy. | Philippe Leff-Gelman Ismael Mancilla-Herrera Monica Flores-Ramos Carlos Cruz-Fuentes Juan Pablo Reyes-Grajeda maría del pilar garcía-cuétara Marielle Danitza Bugnot-Perez David Ellioth Pulido-Ascencio | 2016 | Neuroscience Bulletin2016，32，4： | 17 |
| 4 | Therapy with stem cells in inflammatory bowel disease显示文摘Inflammatory bowel disease(IBD) affects a part of the young population and has a strong impact upon quality of life. The underlying etiology is not known, and the existing treatments are not curative. Furthermore, a significant percentage of patients are refractory to therapy. In recent years there have been great advances in our knowledge of stem cells and their therapeutic applications. In this context, autologous hematopoietic stem cell transplantation(HSCT) has been used in application to severe refractory Crohn's disease(CD), with encouraging results. Allogenic HSCT would correct the genetic defects of the immune system, but is currently not accepted for the treatment of IBD because of its considerable risks. Mesenchymal stem cells(MSCs) have immune regulatory and regenerative properties, and low immunogenicity(both autologous and allogenic MSCs). Based on these properties, MSCs have been used via the systemic route in IBD with promising results, though it is still too soon to draw firm conclusions. Their local administration in perianal CD is the field where most progress has been made in recent years, with encouraging results. The next few years will be decisive for defining the role of such therapy in the management of IBD. | María del Pilar Martínez-Montiel Gonzalo Jesús Gómez-Gómez Ana Isabel Flores | 2014 | World Journal of Gastroenterology2014，20，5： | 13 |
| 5 | Inflammatory status in human hepatic cirrhosis显示文摘This review focuses on new findings about the inflammatory status involved in the development of human liver cirrhosis induced by the two main causes, hepatitis C virus(HCV) infection and chronic alcohol abuse, avoiding results obtained from animal models. When liver is faced to a persistent and/or intense local damage the maintained inflammatory response gives rise to a progressive replacement of normal hepatic tissue by non-functional fibrotic scar. The imbalance between tissue regeneration and fibrosis will determine the outcome toward health recovery or hepatic cirrhosis. In all cases progression toward liver cirrhosis is caused by a dysregulation of mechanisms that govern the balance between activation/homeostasis of the immune system. Detecting differences between the inflammatory status in HCV-induced vs alcoholinduced cirrhosis could be useful to identify specific targets for preventive and therapeutic intervention in each case. Thus, although survival of patients with alcoholic cirrhosis seems to be similar to that of patients with HCV-related cirrhosis(HCV-C), there are important differences in the altered cellular and molecular mechanisms implicated in the progression toward human liver cirrhosis. The predominant features of HCV-C are more related with those that allow viral evasion of the immune defenses, especially although not exclusively, inhibition of interferons secretion, natural killer cells activation and T cell-mediated cytotoxicity. On the contrary, the inflammatory status of alcohol-induced cirrhosis is determined by the combined effect of direct hepatotoxicity of ethanol metabolites and increases of the intestinal permeability, allowing bacteria and bacterial products translocation, into the portal circulation, mesenteric lymph nodes and peritoneal cavity. This phenomenon generates a stronger pro-inflammatory response compared withHCV-related cirrhosis. Hence, therapeutic intervention in HCV-related cirrhosis must be mainly focused to counteract HCV-immune system evasion, while in the case of alcohol-induced cirrhosis it must try to break the inflammatory loop established at the gutmesenteric lymph nodes-peritoneal-systemic axis. | María Martínez-Esparza María Tristán-Manzano Antonio J Ruiz-Alcaraz Pilar García-Penarrubia | 2015 | World Journal of Gastroenterology2015，21，41： | 10 |
| 6 | Gene expression changes in spleens of the wildlife reservoir species,Eurasian wild boar(Sus scrofa),naturally infected with Brucella suis biovar 2显示文摘Brucella suis is responsible for swine brucellosis worldwide.Of the five different B.suis biovars(bv.),bv.2 appears restricted to Europe where it is frequently isolated from wild boar and hares,can infect pigs and can cause human brucellosis.In this study,the differential gene expression profile was characterized in spleens of Eurasian wild boar naturally infected with B.suis bv.2.Of the 20,201 genes analyzed in the microarray,633 and 1,373 were significantly(fold change > 1.8;P < 0.01) upregulated and downregulated,respectively,in infected wild boar.The analysis was focused on genes that were over represented after conditional test for biological process gene ontology.Upregulated genes suggested that B.suis bv.2 infection induced cell maturation,migration and/or proliferation in infected animals.The genes downregulated in infected wild boar impaired the activity of several important cellular metabolic pathways such as metabolism,cytoskeleton organization and biogenesis,immune response and lysosomal function and vesicle-mediated transport.In addition,the response to stress,sperm fertility,muscle development and apoptosis seemed to be also impaired in infected animals.These results suggested that B.suis bv.2 may use strategies similar to other smooth brucellae to facilitate intracellular multiplication and the development of chronic infections.To our knowledge,this is the first report of the analysis of gene expression profile in hosts infected with B.suis bv.2,which is important to understand the molecular mechanisms at the host-pathogen interface in the main reservoir species with possible implications in the zoonotic cycle of the pathogen. | Ruth C.Galindo Pilar M.Muoz María J.de Miguel Clara M.Marin Javier Labairu Miguel Revilla José M.Blasco Christian Gortazar José de la Fuente | 2010 | Journal of Genetics and Genomics2010，37，11： | 6 |
| 7 | Management of primary achalasia: The role of endoscopy显示文摘Achalasia is an oesophageal motor disorder which leads to the functional obstruction of the lower oesophageal sphincter(LES) and is currently incurable. The main objective of all existing therapies is to achieve a reduction in the obstruction of the distal oesophagus in order to improve oesophageal transit, relieve the symptomatology, and prevent long-term complications. The most common treatments used are pneumatic dilation(PD) and laparoscopic Heller myotomy, which involves partial fundoplication with comparable shortterm success rates. The most economic non-surgical therapy is PD, with botulinum toxin injections reserved for patients with a higher surgical risk for whom the former treatment option is unsuitable. A new technology is peroral endoscopic myotomy, postulated as a possible non-invasive alternative to surgical myotomy. Other endoluminal treatments subject to research more recently include injecting ethanolamine into the LES and using a temporary self-expanding metallic stent. At present, there is not enough evidence permitting a routine recommendation of any of these three novel methods. Patients must undergo follow-up after treatment to guarantee that their symptoms are under control and to prevent complications. Most experts are in favour of some form of endoscopic follow-up, however no established guidelines exist in this respect. The prognosis for patients with achalasia is good, although a recurrence after treatment using any method requires new treatment. | Marisol Luján-Sanchis Patricia Suárez-Callol Ana Monzá-Gallego Inmaculada Bort-Pérez Lydia Plana-Campos Luis Ferrer-Barceló Laura Sanchis-Artero María Llinares-Lloret Juan Antonio Tuset-Ruiz Javier Sempere-Garcia-Argüelles Pilar Canelles-Gamir Enrique Medina-Chuliá | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，6： | 5 |
| 8 | Hepatitis C virus genetic variability and evolution显示文摘Hepatitis C virus(HCV) has infected over 170 million people worldwide and creates a huge disease burden due to chronic, progressive liver disease. HCV is a singlestranded, positive sense, RNA virus, member of the Flaviviridae family. The high error rate of RNA-dependent RNA polymerase and the pressure exerted by the host immune system, has driven the evolution of HCV into 7 different genotypes and more than 67 subtypes. HCV evolves by means of different mechanisms of genetic variation. On the one hand, its high mutation rates generate the production of a large number of different but closely related viral variants during infection, usually referred to as a quasispecies. The great quasispecies variability of HCV has also therapeutic implications since the continuous generation and selection of resistant or fitter variants within the quasispecies spectrum might allow viruses to escape control by antiviral drugs. On the other hand HCV exploits recombination to ensure its survival. This enormous viral diversity together with some host factors has made it difficult to control viral dispersal. Current treatment options involve pegylated interferon-α and ribavirin as dual therapy or in combination with a direct-acting antiviral drug, depending on the country. Despite all the efforts put into antiviral therapy studies, eradication of the virus or the development of a preventive vaccine has been unsuccessful so far. This review focuses on current available data reported to date on the genetic mechanisms driving the molecular evolution of HCV populations and its relation with the antiviral therapies designed to control HCV infection. | Natalia Echeverría Gonzalo Moratorio Juan Cristina Pilar Moreno | 2015 | World Journal of Hepatology2015，7，6： | 5 |
| 9 | Residual activity of cetrimide and chlorhexidine on Enterococcus faecalis-infected root canals显示文摘Effective final irrigation regimen is an important step in order to achieve better disinfection and ensure residual antimicrobial effects after root canal preparation. The aim of this study was to compare the residual antimicrobial activity of 0.2% cetrimide, and 0.2% and 2% chlorhexidine in root canals infected with Enterococcus faecalis. Biofilms of E. faecalis were grown on uniradicular roots for 4 weeks. After root canal preparation, root canals were irrigated with 17% ethylenediaminetetraacetic acid(EDTA) to remove the smear layer. The roots were randomly divided into three experimental groups(n526) according to the final irrigating solution: Group I, 5 mL 0.2% cetrimide; Group II, 5 mL 0.2% chlorhexidine; and Group III, 5 mL 2% chlorhexidine. Samples were collected for 50 days to denote the presence of bacterial growth. The proportion of ungrown specimens over 50 days was evaluated using the nonparametric Kaplan–Meier survival analysis. Differences among groups were tested using the log-rank test and the level of statistical significance was set at P,0.05. The highest survival value was found with 2% chlorhexidine, showing statistically significant differences from the other two groups. At 50 days, E. faecalis growth was detected in 69.23% specimens in Groups I and II, and in 34.61% specimens of Group III. There were no significant differences between 0.2% cetrimide and 0.2% chlorhexidine. Final irrigation with 2% chlorhexidine showed greater residual activity than 0.2% chlorhexidine and 0.2% cetrimide in root canals infected with E. faecalis. | Carmen María Ferrer-Luque María Teresa Arias-Moliz Matilde Ruíz-Linares María Elena Martínez García Pilar Baca | 2014 | International Journal of Oral Science2014，6，1： | 5 |
| 10 | Helicobacter pylori CagA protein polymorphisms and their lack of association with pathogenesis显示文摘AIM: To investigate Helicobacter pylori (H. pylori) CagA diversity and to evaluate the association between protein polymorphisms and the occurrence of gastric pathologies. METHODS: One hundred and twenty-two clinical isolates of H. pylori cultured from gastric biopsies obtained from Colombian patients with dyspepsia were included as study material. DNA extracted from isolates was used to determine cagA status, amplifying the C-terminal cagA gene region by polymerase chain reaction. One hundred and six strains with a single amplicon were sequenced and results were used to characterize the 3' variable region of the cagA gene. To establish the number and type of tyrosine phosphorylation motifs Glutamine acid-Proline-Isoleucine-Tyrosine-Alanine (EPI-YA) bioinformatic analysis using Amino Acid Sequence Analyzer-Amino Acid Sequence Analyzer software was conducted. Analysis of the association between the number of EPIYA motifs and the gastric pathology was performed using χ2 test and analysis of the presence of EPIYA-C motifs in relation to the pathology was made by logistic regression odds ratios. Comparisons among EPIYA types found and those reported in GenBank were performed using a proportion test in Statistix Analytical Software version 8.0. RESULTS: After amplification of the 3' of the cagA gene, 106 from 122 isolates presented a single amplicon and 16 showed multiple amplicons. As expected, diversity in the size of the cagA unique fragments among isolates was observed. The 106 strains that presented a single amplicon after 3' cagA amplification came from patients with gastritis (19 patients), atrophic gastritis (21), intestinal metaplasia (26), duodenal ulcer (22) and gastric cancer. DNA sequence analysis showed that the differences in size of 3' cagA unique fragments was attributable to the number of EPIYA motifs: 1.9% had two EPIYA motifs, 62.3% had three, 33.0% had four and 2.8% had five motifs. The majority of tested clinical strains (62.3%) were found to harbor the ABC combination of EPIYA motifs and a significant statistical difference was observed between the frequencies of ABCC tyrosine phosphorylation motifs and Western strains sequences deposited in GenBank. CONCLUSION: The present report describes a lack of association between H. pylori CagA-protein polymorphisms and pathogenesis. ABCC high frequency variations compared with Western-strains sequences deposited in GenBank require more investigation. | Nicole Acosta Andrés Quiroga Pilar Delgado María Mercedes Bravo Carlos Jaramillo | 2010 | World Journal of Gastroenterology2010，16，31： | 5 |
| 11 | Current approach to treatment of minimal hepatic encephalopathy in patients with liver cirrhosis显示文摘Minimal hepatic encephalopathy(MHE)corresponds to the earliest stage of hepatic encephalopathy(HE).MHE does not present clinically detectable neurological-psychiatric abnormalities but is characterized by imperceptible neurocognitive alterations detected during routine clinical examination via neuropsychological or psychometrical tests.MHE may affect daily activities and reduce job performance and quality of life.MHE can increase the risk of accidents and may develop into overt encephalopathy,worsening the prognosis of patients with liver cirrhosis.Despite a lack of consensus on the therapeutic indication,interest in finding novel strategies for prevention or reversion has led to numerous clinical trials;their results are the main objective of this review.Many studies address the treatment of MHE,which is mainly based on the strategies and previous management of overt HE.Current alternatives for the management of MHE include measures to maintain nutritional status while avoiding sarcopenia,and manipulation of intestinal microbiota with non-absorbable disaccharides such as lactulose,antibiotics such as rifaximin,and administration of different probiotics.This review analyzes the results of clinical studies that evaluated the effects of different treatments for MHE. | Segundo Moran Marlene López-Sánchez María del Pilar Milke-García Gustavo Rodríguez-Leal | 2021 | World Journal of Gastroenterology2021，27，22： | 5 |
| 12 | Small intestinal bacterial overgrowth in inactive Crohn's disease:Influence of thiopurine and biological treatment显示文摘AIM:To investigate the influence of thiopurines and biological drugs on the presence of small intestinal bacterial overgrowth(SIBO) in patients with inactive Crohn's disease(CD).METHODS:This was a prospective study in patients with CD in remission and without corticosteroid treatment,included consecutively from 2004 to 2010.SIBO was investigated using the hydrogen glucose breath test.RESULTS:One hundred and seven patients with CD in remission were included.Almost 58%of patients used maintenance immunosuppressant therapy and 19.6%used biological therapy.The prevalence of SIBO was16.8%.No association was observed between SIBO and the use of thiopurine Immunosuppressant(12/62patients),administration of biological drugs(2/21 patients),or with double treatment with an anti-tumor necrosis factor drugs plus thiopurine(1/13 patients).Half of the patients had symptoms that were suggestive of SIBO,though meteorism was the only symptom that was significantly associated with the presence of SIBO on univariate analysis(P<0.05).Multivariate analysis revealed that the presence of meteorism and a fistulizing pattern were associated with the presence of SIBO(P<0.05).CONCLUSION:Immunosuppressants and/or biological drugs do not induce SIBO in inactive CD.Fistulizing disease pattern and meteorism are associated with SIBO. | Cristina Sánchez-Montes Vicente Ortiz Guillermo Bastida Ester Rodríguez María Yago Belén Beltrán Mariam Aguas Marisa Iborra Vicente Garrigues Julio Ponce Pilar Nos | 2014 | World Journal of Gastroenterology2014，20，38： | 4 |
| 13 | Holistic Disaster Risk Evaluation for the Urban Risk Management Plan of Manizales,Colombia显示文摘Disaster risk depends on both the physical vulnerability and a wide range of social, economic, and environmental aspects of a society. For a better risk understanding, a holistic or integrated perspective was considered when risk was assessed for the city of Manizales, Colombia. This assessment accounts not only for the expected physical damage and loss, but also for the socioeconomic vulnerability factors that favor secondorder effects in a disaster. This comprehensive approach allows the identification of different aspects related to physical vulnerability, social fragility, and lack of resilience that can be improved, thus enhancing integrated disaster risk management actions. The outcomes of this comprehensive assessment are currently being used as input to update the disaster risk management plan of Manizales. | Martha Liliana Carreno Omar-Darío Cardona Alex H.Barbat Dora Catalina Suarez María del Pilar Perez Lizardo Narvaez | 2017 | International Journal of Disaster Risk Science2017，8，3： | 4 |
| 14 | Noninvasive diagnosis of vulnerable coronary plaque显示文摘Myocardial infarction and sudden cardiac death are frequently the first manifestation of coronary artery disease.For this reason,screening of asymptomatic coronary atherosclerosis has become an attractive field of research in cardiovascular medicine.Necropsy studies have described histopathological changes associated with the development of acute coronary events.In this regard,thin-cap fibroatheroma has been identified as the main vulnerable coronary plaque feature.Hence,many imaging techniques,such as coronary computed tomography,cardiac magnetic resonance or positron emission tomography,have tried to detect noninvasively these histomorphological characteristics with different approaches.In this article,we review the role of these diagnostic tools in the detection of vulnerable coronary plaque with particular interest in their advantages and limitations as well as the clinical implications of the derived findings. | Eduardo Pozo Pilar Agudo-Quilez Antonio Rojas-González Teresa Alvarado María José Olivera Luis Jesús Jiménez-Borreguero Fernando Alfonso | 2016 | World Journal of Cardiology2016，8，9： | 4 |
| 15 | Isokinetic trunk flexion-extension protocol to assess trunk muscle strength and endurance:Reliability,learning effect,and sex differences显示文摘Purpose:The purpose of this study was to examine the reliability and the learning effect of an isokinetic trunk flexion-extension protocol designed to simultaneously assess trunk muscle strength and endurance.In addition,the effect of the participants’sex on the reliability data was examined.Methods:Fifty-seven healthy and physically active young men(n=28)and women(n=29)performed the isokinetic protocol 5 times,separated by a week between each of the first 4 sessions and by a month between the last 2 sessions.The protocol consisted of performing 4 trials of 15 maximum flexion-extension concentric exertions at 120°/s(range of trunk motion=50°).The absolute and relative peak torque and total work were calculated to assess trunk flexion and extension strength.In addition,endurance ratio,modified endurance ratio,fatigue final ratio,recovery ratio,and modified recovery ratio variables were used for the assessment of trunk muscle endurance in both directions.Results:Regarding the absolute reliability,no relevant changes were found between paired-comparison sessions for most strength and endurance variables,except for total work and relative total work variables in the flexion movement in both sexes.In addition,the typical error of the isokinetic variables was lower than 10%in both males and females,and minimum detectable changes ranged from 7%to 20%,with a tendency to be higher in females and in endurance variables.The strength variables showed high-to-excellent intraclass correlation coefficients(ICCs;>0.74);however,for the endurance variables only the endurance ratio and the modified endurance ratio obtained moderate-to-high ICC values(0.57 | María Pilar García-Vaquero David Barbado Casto Juan-Recio Alejandro López-Valenciano Francisco J.Vera-Garcia | 2020 | Journal of Sport and Health Science2020，9，6： | 4 |
| 16 | New genes emerging for colorectal cancer predisposition显示文摘Colorectal cancer(CRC)is one of the most frequent neoplasms and an important cause of mortality in the developed world.This cancer is caused by both genetic and environmental factors although 35%of the variation in CRC susceptibility involves inherited genetic differences.Mendelian syndromes account for about5%of the total burden of CRC,with Lynch syndrome and familial adenomatous polyposis the most common forms.Excluding hereditary forms,there is an important fraction of CRC cases that present familial aggregation for the disease with an unknown germline genetic cause.CRC can be also considered as a complex disease taking into account the common diseasecommom variant hypothesis with a polygenic model of inheritance where the genetic components of common complex diseases correspond mostly to variants of low/moderate effect.So far,30 common,low-penetrance susceptibility variants have been identified for CRC.Recently,new sequencing technologies including exomeand whole-genome sequencing have permitted to add a new approach to facilitate the identification of new genes responsible for human disease predisposition.By using whole-genome sequencing,germline mutations in the POLE and POLD1 genes have been found to be responsible for a new form of CRC genetic predisposition called polymerase proofreading-associated polyposis. | Clara Esteban-Jurado Pilar Garre Maria Vila Juan José Lozano Anna Pristoupilova Sergi Beltrán Anna Abulí Jenifer Muoz Francesc Balaguer Teresa Ocaa Antoni Castells Josep M Piqué Angel Carracedo Clara Ruiz-Ponte Xavier Bessa Montserrat Andreu Luis Bujanda Trinidad Caldés Sergi Castellví-Bel | 2014 | World Journal of Gastroenterology2014，20，8： | 3 |
| 17 | CagA EPIYA polymorphisms in Colombian Helicobacter pylori strains and their influence on disease-associated cellular responses显示文摘AIM: To investigate the influence of the CagA diversity in Helicobacter pylori (H. pylori ) strains from Colombia on the host cell biology. METHODS: Eighty-four H. pylori-cagA positive strains with different Glu-Pro-Ile-Tyr-Ala (EPIYA) motifs patterns, isolated from patients with gastritis (n=17), atrophic gastritis (n=17), duodenal ulcer (n=16), intestinal metaplasia (n=16) and gastric cancer (n=18), were included. To determine the integrity of the cag pathogenicity island (cag PAI) we evaluated the presence of cagA, cagT, cagE, and cag10 genes by polymerase chain reaction. AGS gastric epithelial cellswere infected with each strain and assayed for translo-cation and tyrosine phosphorylation of CagA by western blot, secretion of interleukin-8 (IL-8) by enzyme-linked immuno sorbent assay after taking supernatants from cocultures and cell elongation induction. For cell elongation quantification, coculture photographs were taken and the proportion of 'hummingbird' cells (>15 μm) was determined. RESULTS: Overall 72% (60/84) of the strains were found to harbor a functional cag PAI. Levels of phos-phorylated CagA were significantly higher for isolates from duodenal ulcer than the ones in strains from gas-tritis, atrophic gastritis, intestinal metaplasia and gastric cancer (49.1% ± 23.1% vs 21.1% ± 19.5%, P < 0.02; 49.1% ± 23.1% vs 26.2%±14.8%, P<0.045; 49.1% ± 23.1% vs 21.5% ± 19.5%, P<0.043 and 49.1% ± 23.1% vs 29.5% ± 27.1%, P < 0.047 respectively). We observed variable IL-8 expression levels ranging from 0 to 810 pg/mL and from 8.8 to 1442 pg/mL at 6 h and 30 h post-infection, respectively. cagPAI-defective strains did not induce detectable levels of IL-8 at 6 h post-infection. At 30 h post-infection all strains induced IL-8 expression in AGS cells, although cagPAI-defective strains induced significantly lower levels of IL-8 than strains with a functional cagPAI (57.1 ± 56.6 pg/mL vs 513.6 ± 338.6 pg/mL,P < 0.0001). We did not observe differences in the extent of cell elongation induction between strains with a functional or a defective cagPAI in 6 h cocultures. At 24 h post infection strains with functionalcagPAI showed high diversity in the extent of hummingbird phenotype induction ranging from 7% to 34%. cag PAI defective strains induced significantly lower levels of elongation than strains with functional cag-PAI with one or more than one EPIYA-C motif (15.1% ± 5.2%vs 18.9% ± 4.7%,P < 0.03; and 15.1% ± 5.2% vs 20.0% ± 5.1%, P < 0.003 respectively). No differences were observed in cellular elongation inductionor IL-8 expression among H. pylori strains bearing one and more than one EPIYA-C motifs, neither at 6 h nor at 24 h of coculture. There were no associations between the levels of induction of cell elongation or IL-8 expression and number of EPIYA motifs or pathology. CONCLUSION: The present work describes a lack of association between H. pylori CagA protein EPIYA motifs variations from Colombian isolates and disease-associated cellular responses. | Carlos Alberto Fajardo Andrés Javier Quiroga Andrea Coronado Karen Labrador Nicole Acosta Pilar Delgado Carlos Jaramillo María Mercedes Bravo | 2013 | World Journal of Gastrointestinal Oncology2013，5，3： | 3 |
| 18 | Coronary angiography findings in cardiac arrest patients with non-diagnostic post-resuscitation electrocardiogram:A comparison of shockable and non-shockable initial rhythms显示文摘AIM To investigate the impact of coronary artery disease in a cohort of patients resuscitated from cardiac arrest with non-diagnostic electrocardiogram.METHODS From March 2004 to February 2016, 203 consecutive patients resuscitated from in or out-of-hospital sudden cardiac arrest and non-diagnostic post-resuscitation electrocardiogram(defined as ST segment elevation or pre-sumably new left bundle branch block) whounderwent invasive coronary angiogram during hospitalization were included. For purpose of analysis and comparison, patients were classified in two groups: Initial shockable rhythm(ventricular tachycardia or ventricular fibrillation; n = 148, 72.9%) and initial non-shockable rhythm(n = 55, 27.1%). Baseline characteristics, coronary angiogram findings including Syntax Score and long-term survival rates were compared. RESULTS Sudden cardiac arrest was witnessed in 95.2% of cases, 66.7% were out-of-hospital patients and 72.4% were male. There were no significant differences in baseline characteristics between groups except for higher mean age(68.1 years vs 61 years, P = 0.001) in the nonshockable rhythm group. Overall 5-year mortality of the resuscitated patients was 37.4%. Patients with non-shockable rhythms had higher mortality(60% vs 29.1%, P < 0.001) and a worst neurological status at hospital discharge based on cerebral performance category score(CPC 1-2: 32.7% vs 53.4%, P = 0.02). Although there were no significant differences in global burden of coronary artery disease defined by Syntax Score(mean Syntax Score: 10.2 vs 10.3, P = 0.96) there was a trend towards a higher incidence of acute coronary lesions in patients with shockable rhythm(29.7% vs 16.4%, P = 0.054). There was also a higher need for ad-hoc percutaneous coronary intervention in this group(21.9% vs 9.1%, P = 0.03). CONCLUSION Initial shockable group of patients had a trend towards higher incidence of acute coronary lesions and higher need of ad-hoc percutaneous intervention vs nonshockable group. | Pedro Martínez-Losas Pablo Salinas Carlos Ferrera María Teresa Nogales-Romo Francisco Noriega María Del Trigo Iván Javier Núnez-Gil Luis Nombela-Franco Nieves Gonzalo Pilar Jiménez-Quevedo Javier Escaned Antonio Fernández-Ortiz Carlos Macaya Ana Viana-Tejedor | 2017 | World Journal of Cardiology2017，9，8： | 3 |
| 19 | Effect of Nd3+doping on structure,microstructure,lattice distortion and electronic properties of TiO_2 nanoparticles显示文摘Doped and undoped TiCh nanoparticles were prepared by Stober method and thermally treated at 600 ℃.The effect of Nd^(3+) ion on the structure and micro structure of anatase-phase TiCh nanocrystals was studied by Rietveld refinement method using X-ray powder diffraction data.Bond lengths,bond angles,and edges distances were analyzed.The phase formation was confirmed by high-resolution transmission electron microscopy.The adjustment of Ti-0 bond length induced by the addition of Nd^(3+) ions,reduced the octahedral distortion and altered the octahedral array in the anatase-phase TiCh nanocrystal.The changes of structure and microstructure were mainly observed for TiCh nanoparticles doped with 0.1 at.%of Nd^(3+) ions and attributed to the cationic substitution of Ti^(4+) ions which promoted changes in the density of states and gap band of TiCh.The dopant insertion resulted in a better structural stability of the nanocrystals that enhanced their charge transference and photocatalytic efficiency. | Balter Trujillo-Navarrete María del Pilar Haro-Vázquez Rosa María Félix-Navarro Francisco Paraguay-Delgado Henry Alvarez-Huerta Sergio Pérez-Sicairos Edgar Alonso Reynoso-Soto | 2017 | Journal of Rare Earths2017，35，3： | 2 |
