| 1 | Preventative effects of a probiotic, Lactobacillus salivarius ssp. salivarius, in the TNBS model of rat colitis显示文摘AIM: To investigate the intestinal anti-inflammatory effect and mechanism of a probiotic Lactobacillus sakuvarius ssp.salivariusCECT5713 in the TNBS model of rat colitis.METHODS: Female Wistar rats (180-200 g) were used in this study. A group of rats were administered orally the probiotic L. salivarius ssp. salivarius (5×108 CFU suspended in 0.5 mL of skimmed milk) daily for 3 wk. Two additional groups were used for reference, a non-colitic and a control colitic without probiotic treatment, which received orally the vehicle used to administer the probiotic. Two weeks after starting the experiment, the rats were rendered colitic by intracolonic administration of 10 mg of TNBS dissolved in 0.25 mL of 500 mL/L ethanol. One week after colitis induction, all animals were killed and colonic damage was evaluated both histologically and biochemically. The biochemical studies performed in colonic homogenates include determination of myeloperoxidase (MPO) activity,glutathione (GSH) content, leukotriene B4 (LTB4) and tumor necrosis factor α (TNF-α) levels, as well as inducible nitric oxide synthase (iNOS) expression. In addition, the luminal contents obtained from colonic samples were used for microbiological studies, in order to determine Lactobacilli and Bifidobacteria counts.RESULTS: Treatment of colitic rats with L. salivarius ssp.salivarius resulted in amelioration of the inflammatory response in colitic rats, when compared with the corresponding control group without probiotic treatment. This antiinflammatory effect was evidenced macroscopically by a significant reduction in the extent of colonic necrosis and/or inflammation induced by the administration of TNBS/ethanol (2.3+0.4 cm vs3.4+0.3 cm in control group,P<0.01) and histologically by improvement of the colonic architecture associated with a reduction in the neutrophil infiltrate in comparison with non-treated colitic rats. The latter was confirmed biochemically by a significant reduction of colonic MPO activity (105.3+26.0 U/g vs180.6±21.9 U/g, P<0.05), a marker of neutrophil infiltration. The beneficial effect was associated with an increase of the colonic GSH content (1 252±42 nmol/g vs 1 087+51 nmol/g, P<0.05),which is depleted in colitic rats, as a consequence of the oxidative stress induced by the inflammatory process. In addition, the treatment of colitic rats with L. salivarius resulted in a significant reduction of colonic TNF-α levels (509.4±68.2 pg/g vs782.9±60.1 pglg, P<0.01) and in a lower colonic iNOS expression, when compared to TNBS control animals without probiotic administration. Finally,treated colitic rats showed higher counts of Lactobacilli species in colonic contents than control colitic rats, whereas no differences were observed in Bifidobacteria counts.CONCLUSION: Administration of the probiotic L. salivarius ssp. salivarius CECT5713 facilitates the recovery of the inflamed tissue in the TNBS model of rat colitis, an effect associated with amelioration of the production of some of the mediators involved in the inflammatory response in the intestine, such as cytokines, including TNF-α and NO. This beneficial effect could be ascribed to its effect on the altered immune response that occurs in this inflammatory condition. | Laura Peran Desiree Camuesco Monica Comalada Ana Nieto Angel Concha Maria Paz Diaz-Ropero Monica Olivares Jordi Xaus Antonio Zarzuelo Julio Galvez | 2005 | World Journal of Gastroenterology2005，11，33： | 17 |

| 3 | GPS and Google Earth based 3D assisted driving system for trucks in surface mines显示文摘In order to reduce the number of surface mining accidents related to low visibility conditions and blind spots of trucks and to provide 3D information for truck drivers and real time monitored truck information for the remote dispatcher, a 3D assisted driving system (3D-ADS) based on the GPS, mesh-wireless networks and the Google-Earth engine as the graphic interface and mine-mapping server, was developed at Virginia Tech. The research results indicate that this 3D-ADS system has the potential to increase reliability and reduce uncertainty in open pit mining operations by customizing the local 3D digital mining map, con-structing 3D truck models, tracking vehicles in real time using a 3D interface and indicating available escape routes for driver safety. | SUN Enji NIETO Antonio LI Zhongxue | 2010 | Mining Science and Technology2010，20，1： | 9 |

| 11 | Lateral patellofemoral ligament reconstruction to restore functional capacity in patients previously undergoing lateral retinacular release显示文摘AIM: To study patient outcomes after surgical correction for iatrogenic patellar instability.METHODS: This retrospective study looked at 17 patients(19 knees) suffering from disabling medial patellar instability following lateral release surgery. All patients underwent lateral patellofemoral ligament(LPFL) reconstruction by a single surgeon. Assessments in all 19 cases included functional outcome scores, range of motion, and assessment for the presence of apprehension sign of the patella to determine if LPFL reconstruction surgery was successful at restoring patellofemoral stability.RESULTS: No patients reported any residual postoperative symptoms of patellar instability. Also no patients demonstrated medial patellar apprehension or examiner induced subluxation with the medial instability test described earlier following LPFL reconstruction. Furthermore, all patients recovered normal range of motion compared to the contralateral limb. For patients with pre and postoperative outcome scores, the mean overall knee injury and osteoarthritis outcome score increased significantly, from 34.39 preoperatively(range: 7.7-70.12) to 69.54 postoperatively(range:26.82-91.46) at final follow-up(P < 0.0001). CONCLUSION: This novel technique for LPFL reconstruction is effective at restoring lateral restraint of the patellofemoral joint and improving joint functionality. | Mitch Beckert Dylan Crebs Michael Nieto Yubo Gao John Albright | 2016 | World Journal of Clinical Cases2016，4，8： | 3 |
| 12 | Toll-like receptor 4 polymorphisms and bacterial infections in patients with cirrhosis and ascites显示文摘AIM To assess the relationship between the presence of toll-like receptor 4(TLR4) polymorphisms and bacterial infections in cirrhotic patients with ascites. METHODS We prospectively included consecutive patients with cirrhosis and ascites hospitalized during a 6-year period. Patients with human immunodeficiency virus(HIV) infection or any other immunodeficiency, patients with advanced hepatocellular carcinoma(beyond Milan's criteria) or any other condition determining poor short-term prognosis, and patients with a permanent urinary catheter were excluded. The presence of D299 G and/or T399 I TLR4 polymorphisms was determined by sequencing and related to the incidence and probability of bacterial infections, other complications of cirrhosis, hepatocellular carcinoma, and mortality during follow-up. A multivariate analysis to identify predictive variables of mortality in the whole series was performed. RESULTS We included 258 patients: 28(10.8%) were carriers of D299G and/or T399I TLR4 polymorphisms(polymorphism group) and 230 patients were not(wildtype group). The probability of developing any bacterial infection at one-year follow-up was 78% in the polymorphism group and 69% in the wild-type group(P = 0.54). The one-year probability of presenting infections caused by gram-negative bacilli(51% vs 44%, P = 0.68), infections caused by gram-positive cocci(49% vs 40%, P = 0.53), and spontaneous bacterial peritonitis(29% vs 34%, respectively, P = 0.99) did not differ between the two groups. The oneyear probability of transplant-free survival was 55% in the polymorphism group and 66% in the wild-type group(P = 0.15). Multivariate analysis confirmed that age, Child-Pugh score, active alcohol intake, previous hepatic encephalopathy, hepatocellular carcinoma and serum creatinine were associated with a higher risk of death during follow-up. CONCLUSION Genetic polymorphisms D299 G and/or T399 I of TLR4 do not seem to play a relevant role in the predisposition of cirrhotic patients with ascites to bacterial infections. | Edilmar Alvarado-Tapias Carlos Guarner-Argente Elida Oblitas Elisabet Sánchez Silvia Vidal Eva Román Mar Concepción Maria Poca Cristina Gely Oana Pavel Juan Camilo Nieto Cándido Juárez Carlos Guarner Germán Soriano | 2018 | World Journal of Hepatology2018，10，1： | 3 |

| 14 | Staining for p53 and Ki-67 increases the sensitivity of EUS-FNA to detect pancreatic malignancy显示文摘AIM:To investigate whether tumor marker staining can improve the sensitivity of endoscopic ultrasound-guided fine needle aspiration(EUS-FNA)to diagnose pancreatic malignancy. METHODS:Patients who underwent EUS-FNA were retrospectively identified.Each EUS-FNA specimen was evaluated by routine cytology and stained for tumor markers p53,Ki-67,carcinoembryonic antigen(CEA) and CA19-9.Sensitivity,specificity,positive and negative predictive values(PPV and NPV),and positive and negative likelihood ratios(PLR and NLR)were calculated in order to evaluate the performance of each test to detect malignancy. RESULTS:Sixty-one specimens had complete sets of stains,yielding 49 and 12 specimens from pancreatic adenocarcinomas and benign pancreatic lesions due to pancreatitis,respectively.Cytology alone had sensitivity and specificity of 41%and 100%to detect malignancy, respectively.In 46%of the specimens,routine cytology alone was deemed indeterminate.The addition of either p53 or Ki-67 increased the sensitivity to 51%and 53%,respectively,with perfect specificity,PPV and PLR (100%,100%and infinite).Both stains in combination increased the sensitivity to 57%.While additional staining with CEA and CA19-9 further increased the sensitivity to 86%,the specificity,PPV and PLR were significantly reduced(at minimum 42%,84%and 1,respectively).Markers in all combinations performed poorly as a negative test(NPV 26%to 47%,and NLR 0.27 and 0.70).CONCLUSION:Immunohistochemical staining for p53 and Ki-67 can improve the sensitivity of EUS-FNA to diagnose pancreatic adenocarcinoma. | Alexander W Jahng Sonya Reicher David Chung Donna Varela Rahul Chhablani Anil Dev Binh Pham Jose Nieto Rose J Venegas Samuel W French Bruce E Stabile Viktor E Eysselein | 2010 | World Journal of Gastrointestinal Endoscopy2010，2，11： | 3 |
| 15 | Zigbee/Google Earth based assisted driving system in mining显示文摘The Assisted Driving System (ADS) for haul trucks operating in surface mining and construction sites is to reduce accidents related to low visibility conditions. This system is based on the GPS, Zigbee, and the Google-Earth engine as the graphic interface and mine-mapping server. The system has the capability to pin-point and track vehicles in real time using a 3D interface, which is based on user-based AutoCAD mine maps using the Google-Earth graphics interface. All equipped vehicles are shown in a 3D mine map stored in a local server through a wireless network. When low visibility conditions are present, the system indicates available exit/escape routes for driver safety. The ADS potentially increases reliability and reduces uncertainty in open pit mining operations. | SUN En-ji NIETO Antonio | 2009 | Mining Science and Technology2009，19，5： | 3 |
| 16 | Dimensions of hepatocellular carcinoma phenotypic diversity显示文摘Hepatocellular carcinoma(HCC) is the 3^(rd) leading cause of cancer-related death worldwide. More than 80% of HCCs arise within chronic liver disease resulting from viral hepatitis, alcohol, hemochromatosis, obesity and metabolic syndrome or genotoxins. Projections based on Western lifestyle and its metabolic consequences anticipate a further increase in incidence, despite recent breakthroughs in the management of viral hepatitis. HCCs display high heterogeneity of molecular phenotypes, which challenges clinical management. However, emerging molecular classifications of HCCs have not yet formed a unified corpus translatable to the clinical practice. Thus, patient management is currently based upon tumor number, size, vascular invasion, performance status and functional liver reserve. Nonetheless, an impressive body of molecular evidence emerged within the last 20 years and is becoming increasingly available to medical practitioners and researchers in the form of repositories. Therefore, the aim this work is to review molecular data underlying HCC classifications and to organize this corpus into the major dimensions explaining HCC phenotypic diversity. Major efforts have been recently made worldwide toward a unifying 'clinically-friendly' molecular landscape. As a result, a consensus emerges on three major dimensions explaining the HCC heterogeneity. In the first dimension, tumor cell proliferation and differentiation enabled allocation of HCCs to two major classes presenting profoundly different clinical aggressiveness. In the second dimension, HCC microenvironment and tumor immunity underlie recent therapeutic breakthroughs prolonging patients' survival. In the third dimension,metabolic reprogramming, with the recent emergence of subclass-specific metabolic profiles, may lead to adaptive and combined therapeutic approaches. Therefore, here we review recent molecular evidence, their impact on tumor histopathological features and clinical behavior and highlight the remaining challenges to translate our cognitive corpus into patient diagnosis and allocation to therapeutic options. | Romain Désert Natalia Nieto Orlando Musso | 2018 | World Journal of Gastroenterology2018，24，40： | 3 |
