| 1 | Acute-on-chronic liver failure:Pathogenesis,prognostic factors and management显示文摘Acute-on-chronic liver failure(ACLF) is increasingly recognized as a complex syndrome that is reversiblein many cases. It is characterized by an acute deterioration of liver function in the background of a pre-existing chronic liver disease often associated with a high short-term mortality rate. Organ failure(OF) is always associated, and plays a key role in determining the course, and the outcome of the disease. The definition of ACLF remains controversial due to its overall ambiguity, with several disparate criteria among various associations dedicated to the study of liver diseases. Although the precise pathogenesis needs to be clarified, it appears that an altered host response to injury might be a contributing factor caused by immune dysfunction, ultimately leading to a pro-inflammatory status, and eventually to OF. The PIRO concept(Predisposition, Insult, Response and Organ Failure) has been proposed to better approach the underlying mechanisms. It is accepted that ACLF is a different and specific form of liver failure, where a precipitating event is always involved, even though it cannot always be ascertained. According to several studies, infections and active alcoholism often trigger ACLF. Viral hepatitis, gastrointestinal haemorrhage, or drug induced liver injury, which can also provoke the syndrome. This review mainly focuses on the physiopathology and prognostic aspects. We believe these features are essential to further understanding and providing the rationale for improveddisease management strategies. | Sara Blasco-Algora José Masegosa-Ataz María Luisa Gutiérrez-García Sonia Alonso-López Conrado M Fernández-Rodríguez | 2015 | World Journal of Gastroenterology2015，21，42： | 45 |
| 2 | Comparative review of vertebroplasty and kyphoplasty显示文摘The aim of this review is to compare the effectiveness of percutaneous vertebroplasty and kyphoplasty to treat pain and improve functional outcome from ver-tebral fractures secondary to osteoporosis and tumor conditions. In 2009, two open randomized controlled trials published in the New England Journal of Medicine questioned the value of vertebroplasty in treating ver-tebral compression fractures. Nevertheless, the prac-tice of physicians treating these conditions has barely changed. The objective of this review is to try to clarify the most important issues, based on our own experi-ence and the reported evidence about both techniques, and to guide towards the most appropriate choice of treatment of vertebral fractures, although many ques-tions still remain unanswered. | Ferno Ruiz Santiago Alicia Santiago Chinchilla Luis Guzmán álvarez Antonio Luis Pérez Abela Maria del Mar Castellano García Miguel Pajares López | 2014 | World Journal of Radiology2014，6，6： | 30 |

| 4 | A guide to diagnosis of iron deficiency and iron deficiency anemia in digestive diseases显示文摘Iron deficiency (ID), with or without anemia, is often caused by digestive diseases and should always be investigated, except in very specific situations, as its causes could be serious diseases, such as cancer. Diagnosis of ID is not always easy. Low serum levels of ferritin or transferrin saturation, imply a situation of absolute or functional ID. It is sometimes difficult to differentiate ID anemia from anemia of chronic diseases, which can coexist. In this case, other parameters, such as soluble transferrin receptor activity can be very useful. After an initial evaluation by clinical history, urine analysis, and serological tests for celiac disease, gastroscopy and colonoscopy are the key diagnostic tools for investigating the origin of ID, and will detect the most important and prevalent diseases. If both tests are normal and anemia is not severe, treatment with oral iron can be indicated, along with stopping any treatment with non-steroidal anti-inflammatory drugs. In the absence of response to oral iron, or if the anemia is severe or clinical suspicion of important disease persists, we must insist on diagnostic evaluation. Repeat endoscopic studies should be considered in many cases and if both still show normal results, investigating the small bowel must be considered. The main techniques in this case are capsule endoscopy, followed by enteroscopy. | Fernando Bermejo Santiago García-López | 2009 | World Journal of Gastroenterology2009，15，37： | 14 |
| 5 | Efficacy of neoadjuvant therapy and surgical rescue for locally advanced hepatoblastomas:10 year single-center experience and literature review显示文摘AIM:To report our experience with long-term outcomes after multimodal management therapy.METHODS:An observational retrospective study was performed containing seven patients with hepatoblastoma(Hbl)treated in our institution,a tertiary referral center,from 2003 to 2011.Demographic,preoperative,surgical,and outcome variables were collected.A survival analysis and a review of the current literature related to combination neoadjuvant chemotherapy and surgical resection on Hbl were performed.RESULTS:The median age at surgery was 14.4 mo,with a male to female ratio of 4:3.Pretext staging at diagnosis was as follows:stageⅠ,4 cases;stageⅡ,2 patients;and stageⅢ,1 case.Mean pretreatment tumor volume was 735 cm3.Five out of seven patients received neoadjuvant chemotherapy according to SIOPEL-3 or SIOPEL-6 protocols.Tumor volume and alphafetoprotein levels significantly dropped after neoadjuvant therapy.Surgical procedures performed included hemihepatectomies,segmentectomies and atypical resection.All patients received chemotherapy after surgery.Median postoperative hospital stay was 8 d.All patients were alive and disease-free after a median follow-up period of 23 mo.With regards to the literature review,seventeen articles were found that were related to our search.CONCLUSION:Our series shows how multimodal management of Hbl,exhaustive control and a meticulous surgical approach leads to almost 100%complete resection with optimal postoperative results. | Dolores Ayllon Teran Oscar Gómez Beltran Rubén Ciria Bru Elena Mateos González María José Pea Rosa Antonio Luque Molina Pedro López Cillero Javier Briceo Delgado | 2014 | World Journal of Gastroenterology2014，20，29： | 12 |
| 6 | 精子DNA完整性与形态超高倍检测在辅助生殖技术妊娠结局中的临床价值显示文摘近年来,涌现出许多重要的男性不育诊疗新技术。本研究旨在探讨精@DNA完整性与精子空泡率检测对以男性不育因素行IvF或IcsI治疗的不育症的治疗结局。本研究针对152对不育症夫妻行ART技术前进行的精子DNA碎片率与形态学超高倍分析进行队列研究。我们发现对妊娠结局最有预测价值的DNA碎片率切点值为25.5%,阴性预测值为72.7%(P=0.02)。在对空泡率的研究中发现,3、4级的空泡精子的最有预测价值切点值为73.5%,阴性预测值为39.4%(P=0.09),差异无统计学意义。总之,当精子DNA碎片率大于25%时,IVF失败的概率增大,而精子形态学超高倍检测结果对预测患者的妊娠结局无明显获益。 | Gemma López Rafael Lafuente Miguel A Checa Ramón Carreras Mario Brassesco | 2013 | Asian Journal of Andrology2013，15，6： | 12 |

| 8 | New aspects in celiac disease显示文摘Celiac disease (CD) is a common autoimmune disorder characterized by an immune response to ingested gluten and has a strong HLA association with HLA- DQ2 and HLA-DQ8 molecules, but human HLA-DQ risk factors do not explain the entire genetic susceptibility to gluten intolerance. CD is caused by the lack of immune tolerance (oral tolerance) to wheat gluten. In this sense, the expression of soluble HLA-G in CD is of special interest because the molecule plays an important role in the induction of immune tolerance. The enhanced expression of soluble HLA-G found in CD may be part of a mechanism to restore the gluten intolerance. In this editorial, we review recent progress in understanding CD in relation to its prevalence, diagnosis and possible mechanisms of pathogenesis. | MI Torres MA López Casado A Ríos | 2007 | World Journal of Gastroenterology2007，13，8： | 10 |

| 10 | Metabolic complications in liver transplant recipients显示文摘The metabolic syndrome(MS), which includes obesity,dyslipidaemia, hypertension and hyperglycaemia according to the most widely accepted definitions now used, is one of the most common post-transplant complications, with a prevalence of 44%-58%. The MS, together with the immunosuppression, is considered the main risk factor for the development of cardiovascular disease(CVD) in transplant recipients, which in turn accounts for 19%-42% of all deaths unrelated to the graft. The presence of MS represents a relative risk for the development of CVD and death of 1.78. On the other hand, non-alcoholic fatty liver disease(NAFLD), considered as the manifestation of the MS in the liver, is now the second leading reason for liver transplantation in the United States after hepatitis C and alcohol. NAFLD has a high rate of recurrence in the liver graft and a direct relation with the worsening of other metabolic disorders, such as insulin resistance or diabetes mellitus. Consequently, it is vitally important to identify and treat as soon as possible such modifiable factors as hypertension, overweight, hyperlipidaemia or diabetes in transplanted patients to thus minimise the impact on patient survival. Additionally, steroid-free regimens are favoured, with minimal immunosuppression to limit the possible effects on the development of the MS. | Miguel Jiménez-Pérez Rocío González-Grande Edith Omonte Guzmán Víctor Amo Trillo Juan Miguel Rodrigo López | 2016 | World Journal of Gastroenterology2016，22，28： | 10 |
| 11 | Association between Helicobacter spp.infections and hepatobiliary malignancies:A review显示文摘Hepatobiliary cancers are highly lethal cancers that comprise a spectrum of invasive carcinomas originating in the liver hepatocellular carcinoma,the bile ducts intrahepatic cholangiocarcinoma and extrahepaticcholangiocarcinoma,the gallbladder and the ampulla of Vater(collectively known as biliary tract cancers).These tumors account for approximately 13% of all annual cancer-related deaths worldwide and for 10%-20% of deaths from hepatobiliary malignancies.Cholangiocarcinoma(CCA) is a devastating disease that displays a poor survival rate for which few therapeutic options are available.Population genetics,geographical and environmental factors,cholelithiasis,obesity,parity,and endemic infection with liver flukes have been identified as risk factors that influence the development of biliary tract tumors.Other important factors affecting the carcinogenesis of these tumors include chronic inflammation,obstruction of the bile ducts,and impaired bile flow.It has been suggested that CCA is caused by infection with Helicobacter species,such as Helicobacter bilis and Helicobacter hepaticus,in a manner that is similar to the reported role of Helicobacter pylori in distal gastric cancer.Due to the difficulty in culturing these Helicobacter species,molecular methods,such as polymerase chain reaction and sequencing,or immunologic assays have become the methods of choice for diagnosis.However,clinical studies of benign or malignant biliary tract diseases revealed remarkable variability in the methods and the findings,and the use of uniform and validated techniques is needed. | Fany Karina Segura-López Alfredo Güitrón-Cantú Javier Torres | 2015 | World Journal of Gastroenterology2015，21，5： | 9 |
| 12 | Post-traumatic hepatic artery pseudoaneurysm treated with endovascular embolization and thrombin injection显示文摘Post-traumatic hepatic artery pseudoaneurysm is unc-ommon,appearing in approximately 1%of hepatic trauma cases.Most are extrahepatic(80%)and have a late onset.Although they are usually asymptomatic, they should always be treated becasue of the high risk of complications,especially breakage.Currently the treatment of choice is endovascular embolization with coils or the exclusion of the pseudoaneurysm using other intravascular devices.Recently there have been accounts of a treatment that combines embolization with coils and image-guided percutaneous human thrombin injection.We present a case of post-traumatichepatic artery pseudoaneurysm that was successfully treated using this combined technique. | Lloret Esta Francisco López Conesa Asunción Capel Alemán Antonio Robles Campos Ricardo Reus Pintado Manuel Marín Hernández Caridad | 2010 | World Journal of Hepatology2010，2，2： | 9 |
| 13 | Applications of finite element simulation in orthopedic and trauma surgery显示文摘Research in different areas of orthopedic and trauma surgery requires a methodology that allows both a more economic approach and the ability to reproduce different situations in an easy way. Simulation models have been introduced recently in bioengineering and could become an essential tool in the study of any physiological unity, regardless of its complexity. The main problem in modeling with finite elements simulation is to achieve an accurate reproduction of the anatomy and a perfect correlation of the different structures, in any region of the human body. Authors have developed a mixed technique, joining the use of a three-dimensional laser scanner Roland Picza captured together with computed tomography(CT) and 3D CT images, to achieve a perfect reproduction of the anatomy. Finite element(FE) simulation lets us know the biomechanical changes that take place after hipprostheses or osteosynthesis implantation and biological responses of bone to biomechanical changes. The simulation models are able to predict changes in bone stress distribution around the implant, so allowing preventing future pathologies. The development of a FE model of lumbar spine is another interesting application of the simulation. The model allows research on the lumbar spine, not only in physiological conditions but also simulating different load conditions, to assess the impact on biomechanics. Different degrees of disc degeneration can also be simulated to determine the impact on adjacent anatomical elements. Finally, FE models may be useful to test different fixation systems, i.e., pedicular screws, interbody devices or rigid fixations compared with the dynamic ones. We have also developed models of lumbar spine and hip joint to predict the occurrence of osteoporotic fractures, based on densitometric determinations and specific biomechanical models, including approaches from damage and fracture mechanics. FE simulations also allow us to predict the behavior of orthopedic splints applied to the correction of deformities, providing the recovering force-displacement and angle-moment curves that characterize the mechanical behavior of the splint in the overall range of movement. | Antonio Herrera Elena Ibarz José Cego?ino Antonio Lobo-Escolar Sergio Puértolas Enrique López Jesús Mateo Luis Gracia | 2012 | World Journal of Orthopedics2012，3，4： | 8 |
| 14 | Intravitreal dexamethasone implants for diabetic macular edema显示文摘AIM: To evaluate the safety and efficacy of a dexamethasone(DEX) intravitreal implant for diabetic macular edema(DME).METHODS: Totally 113 eyes of 84 patients were divided in three subgroups: naive patients(n=11), pseudophakic patients(n=72) and phakic patients(n=30). Inclusive criterion comprised adult diabetic patients with central fovea thickening and impaired visual acuity resulting from DME for whom previous standard treatments showed no improvement in both central macular thickness(CMT) and best corrected visual acuity(BCVA) after at least 3 mo of treatment. Outcome data were obtained from patient visits at baseline and at months 1, 3, 5, 9 and 12 after the first DEX implant injection. At each of these visits, patients underwent measurement of BCVA, a complete eye examination and measurement of CMT and macular volume(MV) carried out with optical coherence tomography(OCT) images. RESULTS: Seventy-three eyes(64.5%) received a single implant, 30(26.5%) received two implants and 10(9%) received three implants. At baseline, average in BCVA, CMT and MV were 43.5±20.8, 462.8±145 and 12.6±2.5 respectively. These values improved significantly at 1 mo(BCVA: 47.2±19.5, CMT: 339.6±120, MV: 11.11±1.4) and 3 mo(BCVA: 53.2±18.1, CMT: 353.8±141, MV: 11.3±1.3)(P≤0.05). At 5 mo(BCVA: 50.9±19.8, CMT: 425±150, MV: 12.27±2.3), 9 mo(BCVA: 48.4±17.6, CMT: 445.5±170, MV: 12.5±2.3) and 12 mo(BCVA: 47.7±18.8, CMT: 413.2±149, MV: 12.03±2.5), improvements in the three parameters were no longer statistically significant and decreased progressively but did not reach baseline values. There were no clinical differences between subgroups. Ocular complications were minimal.CONCLUSION: Patients with DEX implants show maximum efficacy at 3 mo which then declined progressively, but is still better than baseline values at the end of follow-up. | Alicia Pareja-Ríos Paloma Ruiz-de la Fuente-Rodríguez Sergio Bonaque-González Maribel López-Gálvez Virginia Lozano-López Pedro Romero-Aroca | 2018 | International Journal of Ophthalmology(English edition)2018，11，1： | 8 |
| 15 | Improvement in the corrosion protection and bactericidal properties of AZ91D magnesium alloy coated with a microstructured polypyrrole film显示文摘In this work hollow rectangular microtubes of polypyrrole(PPy)films were potentiostatically electrodeposited on magnesium alloy AZ91D in salicylate solution.The substrate was previously anodized under potentiostatic conditions in a molybdate solution in order to improve the adherence of polymer.Finally the duplex film was modified by the incorporation of silver species.The obtained coatings were characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD)and X-ray photoelectron spectroscopies(XPS)and the antimicrobial activity against the bacteria Escherichia coli was evaluated.The corrosion protection properties of the coatings were examined in Ringer solution by monitoring the open circuit potential,polarization techniques and electrochemical spectroscopy(EIS).The duplex coating presents an improved anticorrosive performance with respect to the PPy film.The best results concerning corrosion protection and antibacterial activity were obtained for the silver-modified composite coating. | A.D.Forero López I.L.Lehr L.I.Brugnoni S.B.Saidman | 2018 | Journal of Magnesium and Alloys2018，6，1： | 7 |

| 17 | Subclinical carotid atherosclerosis predicts all-cause mortality and cardiovascular events in obese patients with negative exercise echocardiography显示文摘BACKGROUND Obesity is a major health problem due to its high prevalence. The relationship between obesity and cardiovascular disease is unclear. Some studies agree that certain conditions associated with obesity, such as physical inactivity or cardiovascular risk factors, are responsible for cardiovascular risk excess among obese people. Carotid intima-media thickness and carotid plaques(CP) have been associated with cardiovascular adverse events in healthy populations, and recent data suggest a higher prevalence of subclinical carotid atherosclerosis in obese and metabolically unhealthy patients. However, there are no studies correlating subclinical atherosclerosis and adverse events(AE) in obese subjects.AIM To determine the association between carotid disease and AE in obese patients with negative exercise echocardiography(EE).METHODS From January 1, 2006 to December 31, 2010, 2000 consecutive patients with a suspicion of coronary artery disease were submitted for EE and carotid ultrasonography. Exclusion criteria included previous vascular disease, left ventricular ejection fraction < 50%, positive EE, significant valvular heart disease and inferior to submaximal EE. An AE was defined as all-cause mortality,myocardial infarction and cerebrovascular accident. Subclinical atherosclerosis was defined as CP presence according to Manheim and the American Society of Echocardiography Consensus.RESULTS Of the 652 patients who fulfilled the inclusion criteria, 226(34.7%) had body mass indexes ≥ 30 kg/m2, and 76 of them(33.6%) had CP. During a mean follow-up time of 8.2(2.1) years, 27 AE were found(11.9%). Mean event-free survival at 1, 5 and 10 years was 99.1%(0.6), 95.1%(1.4) and 86.5%(2.7), respectively. In univariate analysis, CP predicted AE [hazard ratio(HR) 2.52, 95% confidence interval(CI) 1.17-5.46; P = 0.019]. In multivariable analysis, the presence of CP remained a predictor of AE(HR 2.26, 95%CI 1.04-4.95, P = 0.041). Other predictors identified were glomerular filtration rate(HR 0.98, 95%CI 0.96-0.99; P= 0.023), peak metabolic equivalents(HR 0.83, 95%CI 0.70–0.99, P = 0.034) and moderate mitral regurgitation(HR 5.02, 95%CI 1.42–17.75, P = 0.012).CONCLUSION Subclinical atherosclerosis defined by CP predicts AE in obese patients with negative EE. These patients could benefit from aggressive prevention measures. | Rafael Vidal-Perez Raúl Franco-Gutiérrez Alberto J Pérez-Pérez Virginia Franco-Gutiérrez Alberto Gascón-Vázquez Andrea López-López Ana María Testa-Fernández Carlos González-Juanatey | 2019 | World Journal of Cardiology2019，11，1： | 7 |
| 18 | Pulmonary vein stenosis:Etiology,diagnosis and management显示文摘Pulmonary vein stenosis(PVS) is rare condition characterized by a challenging diagnosis and unfavorable prognosis at advance stages. At present, injury from radiofrequency ablation for atrial fibrillation has become the main cause of the disease. PVS is characterized by a progressive lumen size reduction of one or more pulmonary veins that, when hemodynamically significant, may raise lobar capillary pressure leading to signs and symptoms such as shortness of breath, cough, and hemoptysis. Image techniques(transesophageal echocardiography, computed tomography, magnetic resonance and perfusion imaging) are essential to reach a final diagnosis and decide an appropriate therapy. In this regard, series from referral centers have shown that surgical and transcatheter interventions may improve prognosis. The purpose of this article is to review the etiology, assessment and management of PVS. | Pablo Pazos-López Cristina García-Rodríguez Alba Guitián-González Emilio Paredes-Galán María ángel De La Guarda álvarez-Moure Marta Rodríguez-álvarez José Antonio Baz-Alonso Elvis Teijeira-Fernández Francisco Eugenio Calvo-Iglesias Andrés íniguez-Romo | 2016 | World Journal of Cardiology2016，8，1： | 6 |
| 19 | Local recurrence of a parosteal osteosarcoma 21 years after incomplete resection显示文摘Parosteal osteosarcoma (POS) is the most common form of surface osteosarcoma. Its symptoms are insidious and its duration prior to diagnosis is considerably longer than that of other types of osteosarcoma. We report a case of POS with a growing mass but no evidence of metastasis. This tumor, which was diagnosed as calcified hematoma with benign characteristics, was incompletely resected in our hospital 21 years before the diagnosis of recurrence. The patient underwent a wide en bloc resection in our hospital and was free of symptoms, with no signs of tumor recurrence or metastasis during a 53-month follow-up. | Andrés Combalia Ernesto Muoz-Mahamud Antonio Palacín Jaume Pomés Vicente López | 2011 | Chinese Journal of Cancer2011，30，12： | 5 |
