| 1 | Achieving the best bowel preparation for colonoscopy显示文摘Bowel preparation is a core issue in colonoscopy,as it is closely related to the quality of the procedure.Patients often find that bowel preparation is the most unpleasant part of the examination.It is widely accepted that the quality of cleansing must be excellent to facilitate detecting neoplastic lesions.In spite of its importance and potential implications,until recently,bowel preparation has not been the subject of much study.The most commonly used agents are high-volume polyethylene glycol(PEG)electrolyte solution and sodium phosphate.There has been some confusion,even in published meta-analyses,regarding which of the two agents provides better cleansing.It is clear now that both PEG and sodium phosphate are effectivewhen administered with proper timing.Consequently,the timing of administration is recognized as one of the central factors to the quality of cleansing.The bowel preparation agent should be administered,at least in part,a few hours in advance of the colonoscopy.Several low volume agents are available,and either new or modified schedules with PEG that usually improve tolerance.Certain adjuvants can also be used to reduce the volume of PEG,or to improve the efficacy of other agents.Other factors apart from the choice of agent can improve the quality of bowel cleansing.For instance,the effect of diet before colonoscopy has not been completely clarified,but an exclusively liquid diet is probably not required,and a low-fiber diet may be preferable because it improves patient satisfaction and the quality of the procedure.Some patients,such as diabetics and persons with heart or kidney disease,require modified procedures and certain precautions.Bowel preparation for pediatric patients is also reviewed here.In such cases,PEG remains the most commonly used agent.As detecting neoplasia is not the main objective with these patients,less intensive preparation may suffice.Special considerations must be made for patients with inflammatory bowel disease,including safety and diagnostic issues,so that the most adequate agent is chosen.Identifying neoplasia is one of the main objectives of colonoscopy with these patients,and the target lesions are often almost invisible with white light endoscopy.Therefore excellent quality preparation is required to find these lesions and to apply advanced methods such as chromoendoscopy.Bowel preparation for patients with lower gastrointestinal bleeding represents a challenge,and the strategies available are also reviewed here. | Adolfo Parra-Blanco Alex Ruiz Manuel Alvarez-Lobos Ana Amorós Juan Cristóbal Gana Patricio Ibáez Akiko Ono Takahiro Fujii | 2014 | World Journal of Gastroenterology2014，20，47： | 37 |

| 5 | Neurotherapeutic potential of erythropoietin after ischemic injury of the central nervous system显示文摘Erythropoietin (EPO) is one of the most successful biopharmaceuticals in history and is used for treating anemia of different origins. However, it became clear that EPO could also work in a neuroprotective, antiapoptotic, antioxidative, angiogenetic and neurotropic way. It causes stimulation of cells to delay cell apoptosis, especially in the central nervous system. In rodent models of focal cerebral ischemia, EPO showed an impressive reduction of infarct size by 30% and improvement of neurobehavioral outcome by nearly 40%. A large animal model dealing with ischemia and reperfusion of the spinal cord showed that EPO could reduce the risk of spinal cord injury significantly. In addition, some clinical studies tested whether EPO works in real live clinical settings. One of the most promising studies showed the innocuousness and improvements in follow-up, outcome scales and in infarct size, of EPO-use in humans suffering from ischemic stroke. Another study ended unfortunately in a negative outcome and an increased overall death rate in the EPO group. The most possible reason was the involvement of patients undergoing simultaneously systemic thrombolysis with recombinant tissue plasminogen activator. An experimental study on rats demonstrated that administration of EPO might exacerbate tissue plasminogen activator-induced brain hemorrhage without reducing the ischemic brain damage. This case shows clearly how useful animal models can be to check negative side effects of a treatment before going into clinical trials. Other groups looked in human trials at the effects of EPO on the outcome after ischemic stroke, relation to circulating endothelial progerdtor cells, aneurysmal subarachnoid hemorrhage, traumatic brain injury, hemoglobin transfusion thresholds and elective first-time coronary artery bypass surgery. Most of the results were pos-让ive, but are based mostly on small group sizes. However, some of the most neglected facts when focusing on experimental setups of ischemia of the central nervous system are issues like age and comorbidities. It might be extremely worthy to consider these points for future projects, because EPO might influence all these factors. | Florian Simon Nicolaos Floros Wiebke Ibing Hubert Schelzig Artis Knapsis | 2019 | Neural Regeneration Research2019，14，8： | 15 |
| 6 | Exosomes as mediators of neuron-glia communication in neuroinflammation显示文摘In recent years,a type of extracellular vesicles named exosomes has emerged that play an important role in intercellular communication under physiological and pathological conditions.These nanovesicles (30–150 nm) contain proteins,RNAs and lipids,and their internalization by bystander cells could alter their normal functions.This review focuses on recent knowledge about exosomes as messengers of neuron-glia communication and their participation in the physiological and pathological functions in the central nervous system.Special emphasis is placed on the role of exosomes under toxic or pathological stimuli within the brain,in which the glial exosomes containing inflammatory molecules are able to communicate with neurons and contribute to the pathogenesis of neuroinflammation and neurodegenerative disorders.Given the small size and characteristics of exosomes,they can cross the blood-brain barrier and be used as biomarkers and diagnosis for brain disorders and neuropathologies.Finally,although the application potential of exosome is still limited,current studies indicate that exosomes represent a promising strategy to gain pathogenic information to identify therapeutically targets and biomarkers for neurological disorders and neuroinflammation. | María Pascual Francesc Ibánez Consuelo Guerri | 2020 | Neural Regeneration Research2020，15，5： | 14 |

| 9 | Review of the treatment of liver hydatid cysts显示文摘A review was carried out in Medline,LILACS and the Cochrane Library.Our database search strategy included the following terms: 'hydatid cyst','liver','management','meta-analysis' and 'randomized controlled trial'.No language limits were used in the literature search.The latest electronic search date was the 7th of January 2014.Inclusion and exclusion criteria: all relevant studies on the assessment of therapeutic methods for hydatid cysts of the liver were considered for analysis.Information from editorials,letters to publishers,low quality review articles and studies done on animals were excluded from analysis.Additionally,well-structured abstracts from relevant articles were selected and accepted for analysis.Standardized forms were designed for data extraction; two investigators entered the data on patient demographics,methodology,recurrence of HC,mean cyst size and number of cysts per group.Four hundred and fourteen articles were identified using the previously described search strategy.After applying the inclusion and exclusion criteria detailed above,57 articles were selected for final analysis: one meta-analysis,9 randomized clinical trials,5 non-randomized comparative prospective studies,7 non-comparative prospective studies,and 34 retrospective studies(12 comparative and 22 noncomparative).Our results indicate that antihelminthic treatment alone is not the ideal treatment for liver hydatid cysts.More studies in the literature support the effectiveness of radical treatment compared with conservative treatment.Conservative surgery with omentoplasty is effective in preventing postoperative complications.A laparoscopic approach is safe in some situations.Percutaneous drainage with albendazole therapy is a safe and effective alternative treatment for hydatid cysts of the liver.Radical surgery with preand post-operative administration of albendazole is the best treatment option for liver hydatid cysts due to low recurrence and complication rates. | Concepción Gomez i Gavara Rafael López-Andújar Tatiana Belda Ibáez José M Ramia ngel ngel Moya Herraiz Francisco Orbis Castellanos Eugenia Pareja Ibars Fernando San Juan Rodríguez | 2015 | World Journal of Gastroenterology2015，21，1： | 8 |
| 10 | Stem cell therapy in the management of shoulder rotator cuff disorders显示文摘Rotator cuff tears are frequent shoulder problems that are usually dealt with surgical repair. Despite improved surgical techniques, the tendon-to-bone healing rate is unsatisfactory due to difficulties in restoring the delicate transitional tissue between bone and tendon. It is essential to understand the molecular mechanisms that determine this failure. The study of the molecular environment during embryogenesis and during normal healing after injury is key in devising strategies to get a successful repair. Mesenchymal stem cells(MSC) can differentiate into different mesodermal tissues and have a strong paracrine, anti-inflammatory, immunoregulatory and angiogenic potential. Stem cell therapy is thus a potentially effective therapy to enhance rotator cuff healing. Promising results have been reported with the use of autologous MSC of different origins in animal studies: they have shown to have better healing properties, increasing the amount of fibrocartilage formation and improving the orientation of fibrocartilage fibers with less immunologic response and reduced lymphocyte infiltration. All these changes lead to an increase in biomechanical strength. However, animal research is still inconclusive and more experimental studies are needed before human application. Future directions include expanded stem cell therapy in combination with growth factors or different scaffolds as well as new stem cell types and gene therapy. | Maria Valencia Mora Miguel A Ruiz Ibán Jorge Díaz Heredia Raul Barco Laakso Ricardo Cuéllar Mariano García Arranz | 2015 | World Journal of Stem Cells2015，7，4： | 6 |
| 11 | Outcome in obscure gastrointestinal bleeding after capsule endoscopy显示文摘AIM: To investigate the clinical impact of capsule endoscopy(CE) after an obscure gastrointestinal bleeding(OGIB) episode, focusing on diagnostic work-up, followup and predictive factors of rebleeding. METHODS: Patients who were referred to Hospital del Mar(Barcelona, Spain) between 2007 and 2009 for OGIB who underwent a CE were retrospectively analyzed. Demographic data, current treatment with non-steroid antiinflammtory drugs or anticoagulant drugs, hemoglobin levels, transfusion requirements, previous diagnostic tests for the bleeding episode, as well as CE findings(significant or non-significant), work-up and patient out-comes were analyzed from electronic charts. Variables were compared by χ 2 analysis and Student t test. Risk factors of rebleeding were assessed by Log-rank test, Kaplan-Meier curves and Cox regression model. RESULTS: There were 105 patients [45.7% women, median age of 72 years old(interquartile range 56-79)] and a median follow-up of 326 d(interquartile range 123-641) included in this study. The overall diagnostic yield of CE was 58.1%(55.2% and 63.2%, for patients with occult OGIB and overt OGIB, respectively). In 73 patients(69.5%), OGIB was resolved. Multivariate analysis showed that hemoglobin levels lower than 8 g/dL at diagnosis [hazard ratios(HR) = 2.7, 95%CI: 1.9-6.3], patients aged 70 years and above(HR = 2.1, 95%CI: 1.2-6.1) and significant findings in CE(HR = 2.4, 95%CI: 1.1-5.8) were independent predictors of rebleeding. CONCLUSION: One third of the patients presented with rebleeding after CE; risk factors were hemoglobin levels < 8 g/dL, age ≥ 70 years or the presence of significant lesions. | Alex Caas-Ventura Lucia Márque Xavier Bessa Josep Maria DedeuDepartment of Gastroenterology Hospital del Mar Research Institute Pompeu Fabra University Marc Puigvehí Sílvia Delgado-Aros Ines Ana Ibáez Agustin Seoane Luis Barranco Felipe Bory Montserrat Andreu Begoa González-Suárez | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，11： | 4 |
| 12 | Enhancement of vitamin A combined vitamin D supplementation on immune response to Bacille Calmette-Guerin vaccine revaccinated in Chinese infants显示文摘Objective:To investigate whether there is an association between diameter of bacille CalmetteGuerin(BCG)sears and effect of purified protein derivative(PPD)reaction anil to determine whether vitamin A(VA)combined vitamin I)(VD)supplementation influences the immune response to BCG revueeinated in Chinese infants.Methods:A cross-section and 3-month community-randomised trial was conducted.A total of 5 629 infants at 3,6 and 12 months of age in Junan County of China were examined for BCG scar fonnation.Then,597 revuccinated infants were randomly assigned to supplementation(n=307)and control(n=290)groups.The supplementation group were daily assigned to 1 500 IU VA and 500 IU VD for 3 months.Then all infants were subjected to skin test with PPD.Results:The diameter of BCG sears was positively con-elated with diameter of skin indurations of PPD(r=0.17,P<0.05)in the 5 629 infants.The rate of positive response to PP1)was higher in the supplementation group than in the control group(96.1%versus 89.7%,P<0.05,prevalence ratio 1.07.95%CI 1.02-1.12).The prevalence ralio of PPD response for the supplementation group compared with that for the control group was 1.07(95%CI 1.01-1.13)for the males and 1.08(95%CI 1.00-1.17)for the females.For the supplementation group,the males got larger tuberculin induration than the females[(0.73±0.2l)cm versus(0.67±0.20)cm.P<0.05)after intervention.Conclusions:The diameter of BCG scars was effectively correlated with PPD response,which indicates BCG scar formation may be an useful tool Io evaluate the effect of tuberculosis prevention.VA combined VD supplementation may play an immunoregulatory rale in BCG revuecination.This may contribute to the prevention of childhood tuberculosis. | Ying Zheng Xue-Gang Li Qiu-Zhen Wang Ai-Guo Ma Ib Christian Bygbjerg Yong-Ye Sun Yong Li Ming-Ci Zheng Xi Wang | 2014 | Asian Pacific Journal of Tropical Medicine2014，7，2： | 3 |

| 15 | 北欧岩高兰(Empetrum)生态系统:功能及其对环境变化的敏感性显示文摘本文回顾了关于北欧地区岩高兰(Empetrum nigrum sap.nigrum和ssp.hermaphroditum)生态系统的知识。因为岩高兰叶片及其枯枝落叶含有丰富的酚,分解缓慢,随着有机质表土层的形成,养分存储于有机养分库中,主要由具有石南状根的植物所吸收利用。黑果岩高兰(Empetrum nigrum)亚种Hermaphroditum是强有力的养分竞争者,并且在演替后期能战胜多数植物。这是化学干扰(他感作用)和资源竞争所致。岩高兰作为一种有机体耐大气污染,在适林海岸石南丛生地,由于大气中大量氮的沉积其生长活力甚至有所增加,但是它对机械干扰及火烧非常敏感。然而,有迹象表明,空气中无机气氮的输入可对岩高兰占优势时所形成的封闭式营养循环产生干扰。 | Knud Tybirk Marie-Charlotte Nilsson Anders Michelsen Hanne Lakkenborg Kristensen Anna shevtsova Morten Tune Strandberg Marianne Johansson Knud Erik Nielsen Torben Riis-Nielsen Beate Strandberg Ib Johansen 萨仁 | 2000 | AMBIO-人类环境杂志2000，29，2： | 3 |

| 17 | Inflammatory bowel disease: A descriptive study of 716 local Chilean patients显示文摘AIM: To demographically and clinically characterize inflammatory bowel disease(IBD) from the local registry and update data previously published by our group.METHODS: A descriptive study of a cohort based on a registry of patients aged 15 years or older who were diagnosed with IBD and attended the IBD program at Clínica Las Condes in Santiago, Chile. The registry was created in April 2012 and includes patients registered up to October 2015. The information was anonymously downloaded in a monthly report, and the information on patients with more than one visit was updated. The registry includes demographic, clinical and disease characteristics, including the Montreal Classification, medical treatment, surgeries and hospitalizations for crisis. Data regarding infection with Clostridium difficile(C. difficile) were incorporated in the registry in 2014. Data for patients who received consultations as second opinions and continued treatment at this institution were also analyzed. RESULTS: The study included 716 patients with IBD: 508 patients(71%) were diagnosed with ulcerative colitis(UC), 196 patients(27%) were diagnosed with Crohn's disease(CD) and 12 patients(2%) were diagnosed with unclassifiable IBD. The UC/CD ratio was 2.6/1. The median age was 36 years(range 16-88), and 58% of the patients were female, with a median age at diagnosis of 29 years(range 5-76). In the past 15 years, a sustained increase in the number of patients diagnosed with IBD was observed, where 87% of the patients were diagnosed between the years 2001 and 2015. In the cohort examined in the present study, extensive colitis(50%) and colonic involvement(44%) predominated in the patients with UC and CD, respectively. In CD patients, nonstricturing/non-penetrating behavior was more frequent(80%), and perianal disease was observed in 28% of the patients. There were significant differences in treatment between UC and CD, with a higher use of corticosteroids, and immunosuppressive and biological therapies was observed in the patients with CD(P < 0.05 and P < 0.01). Significant surgical differences were also observed: 5% of the UC patients underwent surgery, whereas 38% of the CD patients required at least one surgery(P < 0.01). The patients with CD were hospitalized more often during their disease course than the patients with UC(55% and 35% of the patients, respectively; P < 0.01). C. difficile infection was acquired by 5% of the patients in each group at some point during the disease course. Nearly half of the patients consulted at the institution for a second opinion, and 32% of these individuals continued treatment at the institution. CONCLUSION: IBD has continued to increase in the study cohort, slowly approaching the level reported in developed countries. | Daniela Simian Daniela Fluxá Lilian Flores Jaime Lubascher Patricio Ibánez Carolina Figueroa Udo Kronberg Raúl Acuna Mauricio Moreno Rodrigo Quera | 2016 | World Journal of Gastroenterology2016，22，22： | 2 |

| 20 | Electro-tribological properties of diamond like carbon coatings显示文摘Diamond like carbon(DLC)coatings typically present good self-lubricating tribological properties that could be of interest in sliding dielectric contacts in multiple electrical applications.In this work electro-tribological studies have been performed on several DLC coatings against aluminum in different humidity conditions,in which the coefficients of friction(CoFs)and electrical contact resistance(ECR)were continuously monitored.Results show that CoF and ECR data can be linked to the properties of the coatings(thickness,finishing,microstructure,residual stresses,and wettability)and the degradation modes of their tribological and electrical properties.Therefore,electro-tribological data can provide valuable information about the performance of dielectric coatings,the reasons behind it,and assist in the development of the coatings.ECR also shows potential for on-line monitoring of coated parts in operation. | Iñigo BRACERAS Iñigo IBÁNEZ Santiago DOMINGUEZ-MEISTER Xabier VELASCO Marta BRIZUELA Iñaki GARMENDIA | 2020 | Friction2020，8，2： | 2 |
