| 1 | Titanium 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 | 2012 | World Journal of Gastroenterology2012，18，34： | 8 |
| 2 | Irritable bowel syndrome subtypes differ in body awareness, psychological symptoms and biochemical stress markers显示文摘AIM: To elucidate the differences in somatic, psycho-logical and biochemical pattern between the subtypes of irritable bowel syndrome (IBS). METHODS: Eighty IBS patients, 30 diarrhoea pre-dominant (D-IBS), 16 constipation predominant (C-IBS) and 34 alternating IBS (A-IBS) underwent physi-otherapeutic examinations for dysfunctions in body movements and awareness and were compared to an apparently healthy control group (AHC). All groups an-swered questionnaires for gastrointestinal and psycho-logical symptoms. Biochemical variables were analysed in blood. RESULTS: The D-IBS group showed less body aware-ness, less psychological symptoms, a more normal sense of coherence and psychosocial rating as well as higher C-peptide values. C-IBS had a higher degree of body dysfunction and psychological symptoms, as well as the lowest sense of coherence compared to controls and D-IBS. They also demonstrated the most elevated prolactin levels. A-IBS had the lowest degree of body disturbance, deteriorated quality of life and affected bi-ochemical pattern. All subtypes had higher pain scores compared to controls. In addition they all had signifi -cantly increased triglycerides and elevated morning cortisol levels, however, without statistical signifi cance compared with the controls.CONCLUSION: IBS subtypes showed different pro-files in body awareness, somatic and psychological symptoms and in biochemical variables. D-IBS differed compared to the other groups by lowered body aware-ness, less psychological symptoms and a higher sense of coherence and elevated C-peptide values. C-IBS and A-IBS subtypes suffered more from depression and anxiety, associated with a lower quality of life. These differences may be important and will be taken into account in our treatment of these patients. | Elsa M Eriksson Kristina I Andrén Henry T Eriksson Gran K Kurlberg | 2008 | World Journal of Gastroenterology2008，14，31： | 7 |
| 3 | Chronic 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 | 2010 | World Journal of Gastroenterology2010，16，44： | 7 |
| 4 | Bleeding risk assessment in elderly patients with acute coronary syndrome显示文摘Nowadays,elderly people represent a growing population segment with a well known increased risk of both ischemic and bleeding events.Current acute coronary syndrome guidelines,strongly recommend dual antiplatelet therapy(DAPT)with few specific references for aged patients due to lack of evidence.Patients aged>75 years are misrepresented in the classic derivation trials cohorts.Strategies to reduce the bleeding risk in this group of patients are urgently needed for the daily clinical practice.Identify the specific age related bleeding risk factors and the importance of an integral geriatric assessment remains challenging.Some of the available in-hospital and out-hospital bleeding risk scores have shown a lower to moderate predictive ability in older patients and no specific tools are developed in elderly population.The importance of an appropriate vascular access choice,type and duration of antiplatelet drugs is crucial to reduce the bleeding risk.Increase radial approaches and short DAPT duration leads to reduce hemorrhages.One interesting subgroup of patients is those who need chronic anticoagulation therapy after percutaneous coronary intervention,due to their very high risk of bleeding.New alternatives as dual therapy with oral anticoagulation and only one antiplatlet drug should be considered.In current review,we evaluate the available evidence about bleeding risk in elderly. | Lucía Riobóo-Lestón Sergio Raposeiras-Roubin Emad Abu-Assi Andrés I?iguez-Romo | 2019 | Journal of Geriatric Cardiology2019，16，2： | 6 |
| 5 | Feasibility study of computed vs measured high b-value(1400 s/mm2) diffusion-weighted MR images of the prostate显示文摘AIM: To evaluate the impact of computed b = 1400 s/mm2(C-b1400) vs measured b = 1400 s/mm2(M-b1400) diffusion-weighted images(DWI) on lesion detection rate, image quality and quality of lesion demarcation using a modern 3T-MR system based on a small-field-of-view sequence(sFOV). METHODS: Thirty patients(PSA: 9.5 ± 8.7 ng/mL; 68 ± 12 years) referred for magnetic resonance imaging(MRI) of the prostate were enrolled in this study. All measurements were performed on a 3T MR system.For DWI, a single-shot EPI diffusion sequence(b = 0, 100, 400, 800 s/mm2) was utilized. C-b1400 was cal-culated voxelwise from the ADC and diffusion images. Additionally, M-b1400 was acquired for evaluation and comparison. Lesion detection rate and maximum lesion diameters were obtained and compared. Image quality and quality of lesion demarcation were rated accord-ing to a 5-point Likert-type scale. Ratios of lesion-to-bladder as well as prostate-to-bladder signal intensity(SI) were calculated to estimate the signal-to-noise-ratio(SNR). RESULTS: Twenty-four lesions were detected on M-b1400 images and compared to C-b1400 images. C-b1400 detected three additional cancer suspicious lesions. Overall image quality was rated significantly better and SI ratios were significantly higher on C-b1400(2.3 ± 0.8 vs 3.1 ± 1.0, P < 0.001; 5.6 ± 1.8 vs 2.8 ± 0.9, P < 0.001). Comparison of lesion size showed no significant differences between C- and M-b1400(P = 0.22). CONCLUSION: Combination of a high b-value extrap-olation and sFOV may contribute to increase diagnostic accuracy of DWI without an increase of acquisition time, which may be useful to guide targeted prostate biopsies and to improve quality of multiparametric MRI(mMRI) especially under economical aspects in a pri-vate practice setting. | Leonardo K Bittencourt Ulrike I Attenberger Daniel Lima Ralph Strecker Andre de Oliveira Stefan O Schoenberg Emerson L Gasparetto Daniel Hausmann | 2014 | World Journal of Radiology2014，6，6： | 5 |
| 6 | PECS: Towards Personalized Edge Caching for Future Service-Centric Networks显示文摘Mobile operators face the challenge of how to best design a service-centric network that can effectively process the rapidly increasing number of bandwidth-intensive user requests while providing a higher quality of experience(QoE). Existing content distribution networks(CDN) and mobile content distribution networks(mCDN) have both latency and throughput limitations due to being multiple network hops away from end-users. Here, we first propose a new Personalized Edge Caching System(PECS) architecture that employs big data analytics and mobile edge caching to provide personalized service access at the edge of the mobile network. Based on the proposed system architecture, the edge caching strategy based on user behavior and trajectory is analyzed. Employing our proposed PECS strategies, we use data mining algorithms to analyze the personalized trajectory and service usage patterns. Our findings provide guidance on how key technologies of PECS can be employed for current and future networks. Finally, we highlight the challenges associated with realizing such a system in 5G and beyond. | Ming Yan Wenwen Li Chien Aun Chan Sen Bian Chih-Lin I André F.

| 7 | COVID-19-associated diarrhea显示文摘Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)recently emerged as a highly virulent respiratory pathogen that is known as the causative agent of coronavirus disease 2019(COVID-19).Diarrhea is a common early symptom in a significant proportion of patients with SARS-CoV-2 infection.SARS-CoV-2 can infect and replicate in esophageal cells and enterocytes,leading to direct damage to the intestinal epithelium.The infection decreases the level of angiotensinconverting enzyme 2 receptors,thereby altering the composition of the gut microbiota.SARS-CoV-2 elicits a cytokine storm,which contributes to gastrointestinal inflammation.The direct cytopathic effects of SARS-CoV-2,gut dysbiosis,and aberrant immune response result in increased intestinal permeability,which may exacerbate existing symptoms and worsen the prognosis.By exploring the elements of pathogenesis,several therapeutic options have emerged for the treatment of COVID-19 patients,such as biologics and biotherapeutic agents.However,the presence of SARS-CoV-2 in the feces may facilitate the spread of COVID-19 through fecal-oral transmission and contaminate the environment.Thus gastrointestinal SARS-CoV-2 infection has important epidemiological significance.The development of new therapeutic and preventive options is necessary to treat and restrict the spread of this severe and widespread infection more effectively.Therefore,we summarize the key elements involved in the pathogenesis and the epidemiology of COVID-19-associated diarrhea. | Klara Megyeri Áron Dernovics Zaid I I Al-Luhaibi András Rosztóczy | 2021 | World Journal of Gastroenterology2021，27，23： | 2 |
| 8 | Mental health in the post-COVID-19 era:challenges and the way forward显示文摘The COVID-19 pandemic has posed a serious threat to global mental health.Multiple lines of evidence suggest that there is a varying yet considerable increase in mental health issues among the general population and vulnerable groups.12 The aftermath is obscure and speculative from a social,economic,individual and public mental health perspective.Recently published studies support the existence of an emotional epidemic curve,describing a high probability of an increase in the burden of mental health issues in the post-pandemic era.34 Furthermore,previous major public health emergencies showed that more than half of the population devel-oped mental health problems and required mental health intervention.45 There is,therefore,an urgent need to reorganise existing mental health services to address the current unmet needs for mental health and to prepare for future challenges in the postpandemic era in terms of prevention and management. | Ramyadarshni Vadivel Sheikh Shoib Sarah El Halabi Samer El Hayek LamiaàEssam Drita Gashi Bytyçi Ruta Karaliuniene Andre Luiz Schuh Teixeira Sachin Nagendrappa Rodrigo Ramalho Ramdas Ransing Victor Pereira-Sanchez Chonnakarn Jatchavala Frances Nkechi Adiukwu Ganesh Kudva Kundadak | 2021 | General Psychiatry2021，34，1： | 2 |
