| 1 | Alcoholic cardiomyopathy显示文摘Alcohol is the most frequently consumed toxic substance in the world. Low to moderate daily intake of alcohol has been shown to have beneficial effects on the cardiovascular system. In contrast, exposure to high levels of alcohol for a long period could lead to progressive cardiac dysfunction and heart failure. Cardiac dysfunction associated with chronic and excessive alcohol intake is a specific cardiac disease known as alcoholic cardiomyopathy(ACM). In spite of its clinical importance, data on ACM and how alcohol damages the heart are limited. In this review, we evaluate available evidence linking excessive alcohol consumption with heart failure and dilated cardiomyopathy. Additionally, we discuss the clinical presentation, prognosis and treatment of ACM. | Gonzalo Guzzo-Merello Marta Cobo-Marcos Maria Gallego-Delgado Pablo Garcia-Pavia | 2014 | World Journal of Cardiology2014，6，8： | 19 |
| 2 | Therapy with stem cells in inflammatory bowel disease显示文摘Inflammatory bowel disease(IBD) affects a part of the young population and has a strong impact upon quality of life. The underlying etiology is not known, and the existing treatments are not curative. Furthermore, a significant percentage of patients are refractory to therapy. In recent years there have been great advances in our knowledge of stem cells and their therapeutic applications. In this context, autologous hematopoietic stem cell transplantation(HSCT) has been used in application to severe refractory Crohn's disease(CD), with encouraging results. Allogenic HSCT would correct the genetic defects of the immune system, but is currently not accepted for the treatment of IBD because of its considerable risks. Mesenchymal stem cells(MSCs) have immune regulatory and regenerative properties, and low immunogenicity(both autologous and allogenic MSCs). Based on these properties, MSCs have been used via the systemic route in IBD with promising results, though it is still too soon to draw firm conclusions. Their local administration in perianal CD is the field where most progress has been made in recent years, with encouraging results. The next few years will be decisive for defining the role of such therapy in the management of IBD. | María del Pilar Martínez-Montiel Gonzalo Jesús Gómez-Gómez Ana Isabel Flores | 2014 | World Journal of Gastroenterology2014，20，5： | 13 |
| 3 | 四价人乳头瘤病毒疫苗的效力和效果:10年真实世界研究的系统综述显示文摘预防性人乳头瘤病毒(HPV)疫苗接种计划是全球性的重要公共卫生措施。本文分析了四价HPV疫苗对HPV感染和相关疾病的全球影响。系统检索PubMed和Embase数据库2007年1月至2016年2月发表的四价HPV疫苗对感染、肛门生殖器疣、宫颈癌或癌前病变的效力或效果的观察性研究的报道。十年来,真实世界环境中HPV疫苗效果越来越明显,尤其在疫苗接种率较高国家中那些在HPV暴露发生之前接种的女孩。据报道,疫苗可使HPV6、11、16、18感染最多减少约90%,生殖器疣减少约90%,低度宫颈细胞学异常减少约45%,经组织学证实的高度宫颈异常减少约85%。但HPV疫苗接种计划的公共卫生潜力尚未完全实现,HPV相关疾病仍具有较高的发病率和死亡率,因此仍需要提高HPV疫苗接种计划的人群覆盖率。 | Suzanne M.Garland Susanne K.Kjaer Nubia Muoz Stan L.Block Darron R.Brown Mark J.DiNubile Brianna R.Lindsay Barbara J.Kuter Gonzalo Perez Geraldine Dominiak-Felden Alfred J.Saah Rosybel Drury Rituparna Das Christine Velicer 王华庆 | 2018 | 中国病毒病杂志2018，8，4： | 9 |
| 4 | Liver transplantation for cholangiocarcinoma:Current status and new insights显示文摘Cholangiocarcinoma is a malignant tumor of the biliary system that can be classified into intrahepatic(i CCA),perihiliar(ph CCA) and distal. Initial experiences with orthotopic liver transplantation(OLT) for patientswith i CCA and ph CCA had very poor results and this treatment strategy was abandoned. In the last decade,thanks to a strict selection process and a neoadjuvant chemoradiation protocol,the results of OLT for patients with non-resectable phC CA have been shown to be excellent and this strategy has been extended worldwide in selected transplant centers. Intrahepatic cholangiocarcinoma is a growing disease in most countries and can be diagnosed both in cirrhotic and in non-cirrhotic livers. Even though OLT is contraindicated in most centers,recent investigations analyzing patients that were transplanted with a misdiagnosis of HCC and were found to have an iC CA have shown encouraging results. There is some information suggesting that patients with early stages of the disease could benefit from OLT. In this review we analyze the current stateof-the-art of OLT for cholangiocarcinoma as well as the new insights and future perspectives. | Gonzalo Sapisochín Elena Fernández de Sevilla Juan Echeverri Ramón Charco | 2015 | World Journal of Hepatology2015，7，22： | 8 |
| 5 | Helicobacter pylori and corpus gastric pathology are associated with lower serum ghrelin显示文摘AIM To evaluate the association of Helicobacter pylori(H. pylori), cag A genotype, and type of gastric pathology with ghrelin, leptin and nutritional status.METHODS Fasted dyspeptic adults(18-70 years) referred for an upper digestive endoscopy were enrolled in this crosssectional study. Height and weight were assessed for body mass index(BMI) calculation. A sociodemographic survey was administered and nutrient intake was evaluated with 24 h dietary recalls. Serum total ghrelin and leptin levels were analyzed by enzymelinked immunosorbent assay. 13 C-Urea Breath Test was performed and four gastric biopsies were obtained during endoscopy for histopathology and H. pylori DNA amplification and genotyping. Data analysis was performed using χ2, Mann-Whitney U, Kruskal-Wallis tests, Spearman's correlation and linear regression.RESULTS One hundred and sixty-three patients(40.8 ± 14.0 years), 98/65 females/males, were included. Overall, persistent H. pylori prevalence was 53.4%(95%CI: 45.7%-65.8%). Neither nutrient intake nor BMI differed significantly between H. pylori positive and negative groups. Serum ghrelin was significantly lower in infected patients [median 311.0 pg/m L(IQR 230.0-385.5)] than in uninfected ones [median 355.0 pg/m L(IQR 253.8-547.8)](P = 0.025), even after adjusting for BMI and gender(P = 0.03). Ghrelin levels tended to be lower in patients carrying cag A positive strains both in the antrum and the corpus; however, differences with those carrying cag A negative strains did not reach statistical significance(P = 0.50 and P = 0.49, respectively). In addition, the type and severity of gastric pathology in the corpus was associated with lower serum ghrelin(P = 0.04), independently of H.pylori status. Conversely, leptin levels did not differ significantly between infected and uninfected patients [median 1.84 ng/m L(0.80-4.85) vs 1.84 ng/m L(0.50-5.09),(P = 0.51)]. CONCLUSION H. pylori infection and severity of gastric corpus pathology are associated with lower serum ghrelin. Further studies could confirm a lower ghrelin prevalence in cag A-positive patients. | Paula Mantero Gonzalo Sebastián Matus Rodolfo Ernesto Corti Ana María Cabanne Gerardo Gabriel Zerbetto de Palma Liliana Marchesi Olid María Marta Piskorz Marcela Beatriz Zubillaga Mariana Andrea Janjetic Cinthia Gabriela Goldman | 2018 | World Journal of Gastroenterology2018，24，3： | 8 |
| 6 | Endoscopic submucosal dissection in dogs in a World Gastroenterology Organisation training center显示文摘AIM: To evaluate if canine models are appropriate for teaching endoscopy fellows the techniques of endoscopic submucosal dissection (ESD). METHODS: ESD was performed in 10 canine models under general anesthesia, on artificial lesions of the esophagus or stomach marked with coagulation points. After ESD, each canine model was euthanized and surgical resection of the esophagus or stomach was carried out according to 'The Principles of Humane Experimental Technique, Russel and Burch'. The ESD specimens were fixed with needles on cork submerged in a formol solution with the esophagus or stomach, and delivered to the pathology department to be analyzed. RESULTS: ESD was completed without complications using the Hook-knife in five esophageal areas, with a procedural duration of 124 ± 19 min, a length of 27.4 ± 2.6 mm and a width of 21 ± 2.4 mm. ESD was also completed without complications using the IT-knife2 in five gastric areas, with a procedural duration of 92.6 ± 19 min, a length of 32 ± 2.5 mm and a width of 18 ± 3.7 mm. CONCLUSION: ESD is feasible in the normal esopha- gus and stomach of canine models, which are appropriate for teaching this technique. | Miguel A Tanimoto Gonzalo Torres-Villalobos Rikiya Fujita Patricio Santillan-Doherty Jorge Albores-Saavedra German Gutierrez Luis A Martin-del-Campo Carlos Bravo-Reyna Octavio Villanueva Jose J Villalobos Misael Uribe Miguel A Valdovinos | 2010 | World Journal of Gastroenterology2010，16，14： | 7 |

| 8 | Therapeutic options for HER-2 positive breast cancer: Perspectives and future directions显示文摘During the last 15 years we have witnessed an unprecedented expansion in the drugs developed to target human epidermal growth factor receptor-2(HER-2) positive breast cancer. Trastuzumab, pertuzumab, adotrastuzumab emtansine and lapatinib are currently food and drug administration(FDA)-approved for the treatment of breast cancer patients with HER-2 overexpressed. However, given the amount of information gathered from years of uninterrupted clinical research, it is essential to have periodic updates that succinctly recapitulate what we have learnt over these last years and help us to apply that information in our daily practice. This review will pursue that objective. We will summarize the most relevant and updated informationrelated to the state of the art management of HER-2 positive breast cancer in all the clinical scenarios including the adjuvant, neoadjuvant and metastatic settings. But we will also critically appraise that literature in order to highlight some key clinical concepts that should not be overlooked. Lastly, this review will also point out some of the most promising strategies that are currently being tested and may soon become available. | Gonzalo Recondo Jr Enrique Dìaz Canton Màximo de la Vega Martin Greco Gonzalo Recondo Sr Matias E Valsecchi | 2014 | World Journal of Clinical Oncology2014，5，3： | 7 |
| 9 | Stem cell therapy in inflammatory bowel disease: A promising therapeutic strategy?显示文摘Inflammatory bowel diseases are inflammatory, chronic and progressive diseases of the intestinal tract for which no curative treatment is available. Research in other fields with stem cells of different sources and with immunoregulatory cells(regulatory T-lymphocytes and dendritic T-cells) opens up new expectations for their use in these diseases. The goal for stem cell-based therapy is to provide a permanent cure. To achieve this, it will be necessary to obtain a cellular product, original or genetically modified, that has a high migration capacity and homes into the intestine, has high survival after transplantation, regulates the immune reaction while not being visible to the patient's immune system, and repairs the injured tissue. | Ana I Flores Gonzalo J Gómez-Gómez ángeles Masedo-González M Pilar Martínez-Montiel | 2015 | World Journal of Stem Cells2015，7，2： | 7 |
| 10 | Super-resolution compressive spectral imaging via two-tone adaptive coding显示文摘Coded apertures with random patterns are extensively used in compressive spectral imagers to sample the incident scene in the image plane.Random samplings,however,are inadequate to capture the structural characteristics of the underlying signal due to the sparsity and structure nature of sensing matrices in spectral imagers.This paper proposes a new approach for super-resolution compressive spectral imaging via adaptive coding.In this method,coded apertures are optimally designed based on a two-tone adaptive compressive sensing(CS)framework to improve the reconstruction resolution and accuracy of the hyperspectral imager.A liquid crystal tunable filter(LCTF)is used to scan the incident scene in the spectral domain to successively select different spectral channels.The output of the LCTF is modulated by the adaptive coded aperture patterns and then projected onto a lowresolution detector array.The coded aperture patterns are implemented by a digital micromirror device(DMD)with higher resolution than that of the detector.Due to the strong correlation across the spectra,the recovered images from previous spectral channels can be used as a priori information to design the adaptive coded apertures for sensing subsequent spectral channels.In particular,the coded apertures are constructed from the a priori spectral images via a two-tone hard thresholding operation that respectively extracts the structural characteristics of bright and dark regions in the underlying scenes.Super-resolution image reconstruction within a spectral channel can be recovered from a few snapshots of low-resolution measurements.Since no additional side information of the spectral scene is needed,the proposed method does not increase the system complexity.Based on the mutual-coherence criterion,the proposed adaptive CS framework is proved theoretically to promote the sensing efficiency of the spectral images.Simulations and experiments are provided to demonstrate and assess the proposed adaptive coding method.Finally,the underlying concepts are extended to a multi-channel method to compress the hyperspectral data cube in the spatial and spectral domains simultaneously. | CHANG XU TINGFA XU GE YAN XU MA YUHAN ZHANG XI WANG FENG ZHAO GONZALO R.ARCE | 2020 | Photonics Research2020，8，3： | 6 |
| 11 | Glucocorticosteroid therapy in inflammatory bowel diseases: From clinical practice to molecular biology显示文摘Inflammatory bowel diseases(IBDs),such as ulcerative colitis and Crohn's disease,are chronic pathologies associated with a deregulated immune response in the intestinal mucosa,and they are triggered by environmental factors in genetically susceptible individuals.Exogenous glucocorticoids(GCs)are widely used as anti-inflammatory therapy in IBDs.In the past,patients with moderate or severe states of inflammation received GCs as a first line therapy with an important effectiveness in terms of reduction of the disease activity and the induction of remission.However,this treatment often results in detrimental side effects.This downside drove the development of second generation GCs and more precise(non-systemic)drugdelivery methods.Recent clinical trials show that most of these new treatments have similar effectiveness to first generation GCs with fewer adverse effects.The remaining challenge in successful treatment of IBDs concerns the refractoriness and dependency that some patients encounter during GCs treatment.A deeper understanding of the molecular mechanisms underlying GC response is key to personalizing drug choice for IBDs patients to optimize their response to treatment.In this review,we examine the clinical characteristics of treatment with GCs,followed by an in depth analysis of the proposed molecular mechanisms involved in its resistance and dependence associated with IBDs.This thorough analysis of current clinical and biomedical literature may help guide physicians in determining a course of treatment for IBDs patients and identifies important areas needing further study. | Karen Dubois-Camacho Payton A Ottum Daniel Franco-Munoz Marjorie De la Fuente Alejandro Torres-Riquelme David Díaz-Jiménez Mauricio Olivares-Morales Gonzalo Astudillo Rodrigo Quera Marcela A Hermoso | 2017 | World Journal of Gastroenterology2017，23，36： | 6 |
| 12 | Current stage in inflammatory bowel disease: What is next?显示文摘In recent years,the incidence of inflammatory bowel disease(IBD) has been on the rise,extending to countries where it was infrequent in the past. As a result,the gap between high and low incidence countries is decreasing. The disease,therefore,has an important economic impact on the healthcare system. Advances in recent years in pharmacogenetics and clinical pharmacology have allowed for the development of treatment strategies adjusted to the patient profile. Concurrently,new drugs aimed at inflammatory targets have been developed that may expand future treatment options. This review examines advances in the optimization of existing drug treatments and the development of novel treatment options for IBD. | Gonzalo Jesús Gómez-Gómez ángeles Masedo Carmen Yela Maria del Pilar Martínez-Montiel Begona Casís | 2015 | World Journal of Gastroenterology2015，21，40： | 6 |
| 13 | Conversion from calcineurin inhibitors to mTOR inhibitors stabilizes diabetic and hypertensive nephropathy after liver transplant显示文摘AIM: To investigate if conversion to the mammalian target of rapamycin inhibitors(mTORi) improves renal function in diabetic and/or hypertensive liver transplant patients immunosuppressed with tacrolimus or cyclosporine.METHODS: The study included 86 liver graft recipients immunosuppressed with mTORi treatment after orthotopic liver transplantation(OLT), including all liver recipients with worsening renal function before conversion to mTORi(n = 55 patients) and recipients with normal renal function who converted to m TORi for other reasons(n = 31 patients). We identified patients with diabetes mellitus(n = 28), arterial hypertension(n = 27), proteinuria(n = 27) and all three factors(n = 8)(some patients have hypertension and diabetes and no proteinuria). The primary endpoint was evolution in renal function defined as the development in plasma creatinine as a function of diabetes mellitus(DM), hypertension(HT) or proteinuria. We required elevated serum creatinine for at least two weeks to define renal dysfunction.RESULTS: Only patients that converted because of renal failure with plasma creatinine levels > 1.5 mg/dL showed an improvement of renal function(2.14 to 1.77 mg/dL)(P = 0.02). Patients with DM showed no improvement of serum creatinine levels(1.31 mg/dL to 1.37 mg/dL) compared with non DM patients(1.31 mg/dL to 1.15 mg/dL)(P = 0.01), HT patients(1.48 mg/dL to 1.5 mg/dL) with non HT patients(1.21mg/d L to 1.08 mg/dL) and patients with proteinuria(1.44 mg/dL to 1.41 mg/dL) and no proteinuria(1.31 mg/dL to 1.11 mg/dL). CONCLUSION: In OLT recipients with diabetes or hypertensive nephropathy, conversion to m TORi does not improve renal function but stabilizes plasma levels of creatinine. Proteinuria is not a contraindication to conversion to m TORi; it also stabilizes renal function. Conversion to m TORi should only be avoided in patients with diabetes, hypertension and proteinuria. | José M álamo Claudia Olivares Lydia Barrera Luis M Marín Gonzalo Suarez Carmen Bernal Juan Serrano Jordi Muntané Francisco J Padillo Miguel A Gómez | 2015 | World Journal of Transplantation2015，5，1： | 6 |
| 14 | Hepatitis C virus genetic variability and evolution显示文摘Hepatitis C virus(HCV) has infected over 170 million people worldwide and creates a huge disease burden due to chronic, progressive liver disease. HCV is a singlestranded, positive sense, RNA virus, member of the Flaviviridae family. The high error rate of RNA-dependent RNA polymerase and the pressure exerted by the host immune system, has driven the evolution of HCV into 7 different genotypes and more than 67 subtypes. HCV evolves by means of different mechanisms of genetic variation. On the one hand, its high mutation rates generate the production of a large number of different but closely related viral variants during infection, usually referred to as a quasispecies. The great quasispecies variability of HCV has also therapeutic implications since the continuous generation and selection of resistant or fitter variants within the quasispecies spectrum might allow viruses to escape control by antiviral drugs. On the other hand HCV exploits recombination to ensure its survival. This enormous viral diversity together with some host factors has made it difficult to control viral dispersal. Current treatment options involve pegylated interferon-α and ribavirin as dual therapy or in combination with a direct-acting antiviral drug, depending on the country. Despite all the efforts put into antiviral therapy studies, eradication of the virus or the development of a preventive vaccine has been unsuccessful so far. This review focuses on current available data reported to date on the genetic mechanisms driving the molecular evolution of HCV populations and its relation with the antiviral therapies designed to control HCV infection. | Natalia Echeverría Gonzalo Moratorio Juan Cristina Pilar Moreno | 2015 | World Journal of Hepatology2015，7，6： | 5 |
| 15 | Determinants of percutaneous coronary intervention success in repeat chronic total occlusion procedures following an initial failed attempt显示文摘AIM To investigate the rates and determinants of success of repeat percutaneous coronary intervention(PCI) following an initial failed attempt at recanalising the chronic total occlusions(CTO) percutaneously.METHODS In 445 consecutive first attempt CTO-PCI procedures in our institution,procedural failure occurred in 149(33.5%). Sixty-four re-PCI procedures were performed in 58 patients(39%) all had a single CTO. Procedural and outcome data in the re-PCI population was entered into the institutional database. A retrospective analysis of clinical,angiographic and procedural data was performed. RESULTS Procedural success was achieved in 41(64%) procedures. Univariate analysis of clinical and angiographic characteristics showed that re-PCI success was associated with intravascular ultrasound(IVUS) guidance(19.5% vs 0%,P = 0.042),while failure was associated with severecalcification(30.4% vs 9.7%,P = 0.047) and a JCTO score > 3(56.5% vs 17.1% P = 0.003). Following multiple regression analysis the degree of lesion complexity(J-CTO score > 3),IVUS use,involvement of an experienced CTO operator and LAD CTO location were significant predictors of successful re-PCI. Overall the complication rate was low,with the only MACCE two periprocedural MI's neither of which required intervention. CONCLUSION Re-PCI substantially increases the overall success rate of CTO revascularization. Predictors of re-PCI success included the use of IVUS,the involvement of an experienced CTO operator in the repeat attempt and the location of the CTO. | Cecilia Cuevas Nicola Ryan Alicia Quirós Juan Gustavo Del Angel Nieves Gonzalo Pablo Salinas Pilar Jiménez-Quevedo Luis Nombela-Franco Ivan Nunez-Gil Antonio Fernandez-Ortiz Carlos Macaya Javier Escaned | 2017 | World Journal of Cardiology2017，9，4： | 5 |
| 16 | Clinical-pathological and molecular characterization of long-term survivors with advanced non-small cell lung cancer显示文摘Objective:Long-term survivors(LS)of non-small cell lung cancer(NSCLC)without driver alterations,displaying an overall survival(OS)of more than 3 years,comprise around 10%of cases in several series treated with chemotherapy.There are classical prognosis factors for these cases[stage,Eastern Cooperative Oncology Group(ECOG),etc.],but more data are required in the literature.In this multi-center study,we focused on LS of advanced NSCLC with OS above 36 months to perform a clinical-pathological and molecular characterization.Methods:In the first step,we conducted a clinical-pathological characterization of the patients.Afterwards,we carried out a genetic analysis by comparing LS to a sample of short-term survivors(SS)(with an OS less than 9 months).We initially used whole-genome RNA-seq to identify differentiating profiles of LS and SS,and later confirmed these with reverse transcription-polymerase chain reaction(RT-PCR)for the rest of the samples.Results:A total of 94 patients were included,who were mainly men,former smokers,having adenocarcinoma(AC)-type NSCLC with an ECOG of 0-1.We obtained an initial differential transcriptome expression,displaying 5 over-and 33 under-expressed genes involved in different pathways:namely,the secretin receptor,surfactant protein,trefoil factor 1(T FF1),serpin,Ca-channels,and Tolllike receptor(TLRs)families.Finally,RT-PCR analysis of 40(20 LS/20 SS)samples confirmed that four genes(surfactant proteins and SFTP)were significantly down-regulated in SS compared to LS by using an analysis of covariance(ANCOVA)model:SFTPA1(P=0.023),SFTPA2(P=0.027),SFTPB{P=0.02),and SFT PC(P=0.047).Conclusions:We present a sequential genetic analysis of a sample of NSCLCLS with no driver alterations,obtaining a differential RNA-seq/RT-PCR profile showing an abnormal expression of SF genes. | Juan Moreno-Rubio Santiago Ponce Rosa Alvarez Maria Eugenia Olmedo Sandra Falagan Xabier Mielgo Fatima Navarro Patricia Cruz Luis Cabezon-Gutierrez Carlos Aguado Gonzalo Colmenarejo Marta Munoz-Fernandez de Leglaria Ana Belen Enguita Maria Cebollero Amparo Benito Isabel Alemany Carolina del Castillo Ricardo Ramos Ana Ramirez de Molina Enrique Casado Maria Sereno | 2020 | Cancer Biology & Medicine2020，17，2： | 4 |
| 17 | Air-core fiber distribution of hybrid vector vortex-polarization entangled states显示文摘Entanglement distribution between distant parties is one of the most important and challenging tasks in quantum communication.Distribution of photonic entangled states using optical fiber links is a fundamental building block toward quantum networks.Among the different degrees of freedom,orbital angular momentum(OAM)is one of the most promising due to its natural capability to encode high dimensional quantum states.We experimentally demonstrate fiber distribution of hybrid polarization-vector vortex entangled photon pairs.To this end,we exploit a recently developed air-core fiber that supports OAM modes.High fidelity distribution of the entangled states is demonstrated by performing quantum state tomography in the polarization-OAM Hilbert space after fiber propagation and by violations of Bell inequalities and multipartite entanglement tests.The results open new scenarios for quantum applications where correlated complex states can be transmitted by exploiting the vectorial nature of light. | Daniele Cozzolino Emanuele Polino Mauro Valeri Gonzalo Carvacho Davide Bacco NicoloSpagnolo Leif K.Oxenløwe Fabio Sciarrino | 2019 | Advanced Photonics2019，1，4： | 4 |
| 18 | New insights into the pathophysiology of achalasia and implications for future treatment显示文摘Idiopathic achalasia is an archetype esophageal motor disorder, causing significant impairment of eating ability and reducing quality of life. The pathophysiological underpinnings of this condition are loss of esophageal peristalsis and insufficient relaxation of the lower esophageal sphincter(LES). The clinical manifestations include dysphagia for both solids and liquids, regurgitation of esophageal contents, retrosternal chest pain, cough, aspiration, weight loss and heartburn. Even though idiopathic achalasia was first described more than 300 years ago, researchers are only now beginning to unravel its complex etiology and molecular pathology. The most recent findings indicate an autoimmune component, as suggested by the presence of circulating anti-myenteric plexus autoantibodies, and a genetic predisposition, as suggested by observed correlations with other well-defined genetic syndromes such as Allgrove syndrome and multiple endocrine neoplasia type 2 B syndrome. Viral agents(herpes, varicella zoster) have also been proposed as causative and promoting factors. Unfortunately, the therapeutic approaches available today do not resolve the causes of the disease, and only target the consequential changes to the involved tissues, such as destruction of the LES, rather than restoring or modifying the underlying pathology. New therapies should aim to stop the disease at early stages, thereby preventing the consequential changes from developing and inhibiting permanent damage. This review focuses on the known characteristics of idiopathic achalasia that will help promote understanding its pathogenesis and improve therapeutic management to positively impact the patient's quality of life. | Janette Furuzawa-Carballeda Samuel Torres-Landa Miguel ángel Valdovinos Enrique Coss-Adame Luis A Martín del Campo Gonzalo Torres-Villalobos | 2016 | World Journal of Gastroenterology2016，22，35： | 4 |
| 19 | Validity of automated refraction after segmented refractive multifocal intraocular lens implantation显示文摘AIM: To evaluate the clinical utility of automated refraction(AR) and keratometry(KR) compared with subjective or manifest refraction(MR) after cataract or refractive lens exchange surgery with implantation of Lentis Mplus X(Oculentis GmbH) refractive multifocal intraocular lens(IOL).METHODS: Eighty-six eyes implanted with the Lentis Mplus X multifocal IOL were included. MR was performed in all patients followed by three consecutive AR measurements using the Topcon KR-8000 autorefractor. Assessment of repeatability of consecutive AR before and after dilation with phenylephrine 10%, and comparison of the AR and KR with MR using vector analysis were performed at 3 mo follow-up.RESULTS: Analysis showed excellent repeatability of the AR measurements. Linear regression of AR versus MR showed good correlation for sphere and spherical equivalent, whereas the correlation for astigmatism was low. The mean difference AR-MR was-1.28±0.29 diopters(D) for sphere. Astigmatism showed better correlation between KR and MR. CONCLUSION: We suggest AR sphere plus 1.25 D and the KR cylinder as the starting point for MR in eyes with a Lentis Mplus X multifocal IOL. If AR measurements are equal to MR, decentration of the IOL should be suspected. | Cesar Albarran-Diego Gonzalo Munoz Stephanie Rohrweck Satiago Garcia-Lazaro Jose Ricardo Albero | 2017 | International Journal of Ophthalmology(English edition)2017，10，11： | 3 |
| 20 | Pilot study of atomoxetine in patients with Parkinson’s disease and dopa-unresponsive Freezing of Gait显示文摘Background:Freezing of gait(FoG)is a common and debilitating condition in Parkinson’s disease(PD)associated with executive dysfunction.A subtype of FoG does not respond to dopaminergic therapy and may be related to noradrenergic deficiency.This pilot study explores the effects of atomoxetine on gait in PD patients with dopaunresponsive FoG using a novel paradigm for objective gait assessment.Findings:Ten patients with PD and dopa-unresponsive FoG were enrolled in this eight-week open label pilot study.Assessments included an exploratory gait analysis protocol that quantified spatiotemporal parameters during straight-away walking and turning,while performing a dual task.Clinical,and subjective assessments of gait,quality of life,and safety were also administered.The primary outcome was a validated subjective assessment for FoG(FOG-Q).Atomoxetine was well tolerated,however,no significant change was observed in the primary outcome.The gait analysis protocol correlated well with clinical scales,but not with subjective assessments.DBS patients were more likely to increase gait velocity(p=0.033),and improved in other clinical assessments.Conclusions:Objective gait analysis protocols assessing gait while dual tasking are feasible and useful for this patient population,and may be superior correlates of FoG severity than subjective measures.These findings can inform future trials in this population. | Gonzalo J.Revuelta Aaron Embry Jordan J.Elm Chris Gregory Amy Delambo Steve Kautz Vanessa K.Hinson | 2015 | Translational Neurodegeneration2015，4，1： | 3 |
