1Recent advances in gastric cancer early diagnosis显示文摘Gastric cancer(GC) remains an important cause of cancer death worldwide with a high mortality rate due to the fact that the majority of GC cases are diagnosed at an advanced stage when the prognosis is poor and the treatment options are limited. Unfortunately, the existing circulating biomarkers for GC diagnosis and prognosis display low sensitivity and specificity and the GC diagnosis is based only on the invasive procedures such as upper digestive endoscopy. There is a huge need for less invasive or non-invasive tests but also highly specific biomarkers in case of GC. Body fluids such as peripheral blood, urine or saliva,stomach wash/gastric juice could be a source of specific biomarkers, providing important data for screening and diagnosis in GC. This review summarized the recently discovered circulating molecules such as microRNAs, long non-coding RNAs, circular RNAs, which hold the promise to develop new strategies for early diagnosis of GC.Laura Necula Lilia Matei Denisa Dragu Ana I Neagu Cristina Mambet Saviana Nedeianu Coralia Bleotu Carmen C Diaconu Mihaela Chivu-Economescu 2019World Journal of Gastroenterology2019,25,17:70
2Acute pancreatitis:The stress factor显示文摘Acute pancreatitis is an inflammatory disorder of the pancreas that may cause life-threatening complications.Etiologies of pancreatitis vary,with gallstones accounting for the majority of all cases,followed by alcohol.Other causes of pancreatitis include trauma,ischemia,mechanical obstruction,infections,autoimmune,hereditary,and drugs.The main events occurring in the pancreatic acinar cell that initiate and propagate acute pancreatitis include inhibition of secretion,intracellular activation of proteases,and generation of inflammatory mediators.Small cytokines known as chemokines are released from damaged pancreatic cells and attract inflammatory cells,whose systemic action ultimately determined the severity of the disease.Indeed,severe forms of pancreatitis may result in systemic inflammatory response syndrome and multiorgan dysfunction syndrome,characterized by a progressive physiologic failure of several interdependent organ systems.Stress occurs when homeostasis is threatened,and stressors can include physical or mental forces,or combinations of both.Depending on the timing and duration,stress can result in beneficial or harmful consequences.While it is well established that a previous acute-short-term stress decreases the severity of experimentally-induced pancreatitis,the worsening effects of chronic stress on the exocrine pancreas have received relatively little attention.This review will focus on the influence of both prior acute-short-term and chronic stress in acute pancreatitis.Marcelo G Binker Laura I Cosen-Binker 2014World Journal of Gastroenterology2014,20,19:10
3Titanium dioxide induced inflammation in the small intestine显示文摘AIM:To investigate the effects of titanium dioxide (TiO2) nanoparticles (NPTiO 2 ) and microparticles (MPTiO 2 ) on the inflammatory response in the small intestine of mice. METHODS: Bl 57/6 male mice received distilled water suspensions containing TiO 2 (100 mg/kg body weight) as NPTiO 2 (66 nm), or MPTiO 2 (260 nm) by gavage for 10 d, once a day; the control group received only distilled water. At the end of the treatment the duodenum, jejunum and ileum were extracted for assessment of cytokines, inflammatory cells and titanium content. The cytokines interleukin (IL)-1b, IL-4, IL-6, IL-8, IL-10, IL-12, IL-13, IL-17, IL-23, tumor necrosis factor-α (TNF-α), intracellular interferon-γ (IFN-γ) and transforming growth factor-β (TGF-β) were evaluated by enzyme-linked immunosorbent assay in segments of jejunum and ileum (mucosa and underlying muscular tissue). CD4 + and CD8 + T cells, natural killer cells, and dendritic cells were evaluated in duodenum, jejunum and ileum samples fixed in 10% formalin by immuno-histochemistry. The titanium content was determined by inductively coupled plasma atomic emission spectrometry. RESULTS: We found increased levels of T CD4 + cells (cells/mm 2 ) in duodenum:NP 1240 ± 139.4, MP 1070 ± 154.7 vs 458 ± 50.39 (P < 0.01); jejunum:NP 908.4 ± 130.3, MP 813.8 ± 103.8 vs 526.6 ± 61.43 (P < 0.05); and ileum:NP 818.60 ± 123.0, MP 640.1 ± 32.75 vs 466.9 ± 22.4 (P < 0.05). In comparison to the control group, the groups receiving TiO 2 showed a statistically significant increase in the levels of the inflammatory cytokines IL-12, IL-4, IL-23, TNF-α, IFN-γ and TGF-β. The cytokine production was more pronounced in the ileum (mean ± SE):IL-12: NP 33.98 ± 11.76, MP 74.11 ± 25.65 vs 19.06 ± 3.92 (P < 0.05); IL-4: NP 17.36 ± 9.96, MP 22.94 ± 7.47 vs 2.19 ± 0.65 (P < 0.05); IL-23: NP 157.20 ± 75.80, MP 134.50 ± 38.31 vs 22.34 ± 5.81 (P < 0.05); TNFα: NP 3.71 ± 1.33, MP 5.44 ± 1.67 vs 0.99± 019 (P < 0.05); IFNγ: NP 15.85 ± 9.99, MP 34.08 ± 11.44 vs 2.81 ± 0.69 (P < 0.05); and TGF-β: NP 780.70 ± 318.50, MP 1409.00 ± 502.20 vs 205.50 ± 63.93 (P < 0.05). CONCLUSION:Our findings indicate that TiO2 particles induce a Th1-mediated inflammatory response in the small bowel in mice.Carolina Maciel Nogueira Walter Mendes de Azevedo Maria Lucia Zaidan Dagli Sérgio Hiroshi Toma AndréZonetti de Arruda Leite Maria Laura Lordello Iêda Nishitokukado Carmen Lúcia Ortiz-Agostinho Maria IrmaSeixas Duarte Marcelo Alves Ferreira Aytan Miranda Sipahi 2012World Journal of Gastroenterology2012,18,34:8
4Chronic stress sensitizes rats to pancreatitis induced by cerulein:Role of TNF-α显示文摘AIM:To investigate chronic stress as a susceptibility factor for developing pancreatitis,as well as tumor necrosis factor-α (TNF-α) as a putative sensitizer.METHODS:Rat pancreatic acini were used to analyze the influence of TNF-α on submaximal (50 pmol/L) cholecystokinin (CCK) stimulation.Chronic restraint (4 h every day for 21 d) was used to evaluate the effects of submaximal (0.2 μg/kg per hour) cerulein stimulation on chronically stressed rats.RESULTS:In vitro exposure of pancreatic acini toTNF-α disorganized the actin cytoskeleton.This was further increased by TNF-α/CCK treatment,which additionally reduced amylase secretion,and increased trypsin and nuclear factor-κB activities in a protein-kinase-C δ and ε-dependent manner.TNF-α/CCK also enhanced caspases' activity and lactate dehydrogenase release,induced ATP loss,and augmented the ADP/ATP ratio.In vivo,rats under chronic restraint exhibited elevated serum and pancreatic TNF-α levels.Serum,pancreatic,and lung inflammatory parameters,as well as caspases' activity in pancreatic and lung tissue,were substantially enhanced in stressed/cerulein-treated rats,which also experienced tissues' ATP loss and greater ADP/ATP ratios.Histological examination revealed that stressed/cerulein-treated animals developed abundant pancreatic and lung edema,hemorrhage and leukocyte infiltrate,and pancreatic necrosis.Pancreatitis severity was greatly decreased by treating animals with an anti-TNF-αantibody,which diminished all inflammatory parameters,histopathological scores,and apoptotic/necrotic markers in stressed/cerulein-treated rats.CONCLUSION:In rats,chronic stress increases susceptibility for developing pancreatitis,which involves TNF-α sensitization of pancreatic acinar cells to undergo injury by physiological cerulein stimulation.Marcelo G Binker Andres A Binker-Cosen Daniel Richards Herbert Y Gaisano Rodica H de Cosen Laura I Cosen-Binker 2010World Journal of Gastroenterology2010,16,44:7
