2Spontaneous rupture of hepatic hemangiomas:A review of the literature显示文摘Hepatic hemangiomas are congenital vascular malformations,considered the most common benign mesenchymal hepatic tumors,composed of masses of blood vessels that are atypical or irregular in arrangement and size. Hepatic hemangiomas can be divided into two major groups:capillary hemangiomas and cavernous hemangiomas These tumors most frequently affect females (80%) and adults in their fourth and fifth decades of life. Most cases are asymptomatic although a few patients may present with a wide variety of clinical symptoms,with spontaneous or traumatic rupture being the most severe complication. In cases of spontaneous rupture,clinical manifestations consist of sudden abdominal pain,and anemia secondary to ahaemoperitoneum. Disseminated intravascular coagulopathy can also occur. Haemodynamic instability and signs of hypovolemic shock appear in about one third of cases. As the size of the hemangioma increases,so does the chance of rupture. Imaging studies used in the diagnosis of hepatic hemangiomas include ultrasonography,dynamic contrast-enchanced computed tomography scanning,magnetic resonance imaging,hepatic arteriography,digital subtraction angiography,and nuclear medicine studies. In most cases hepatic hemangiomas are asymptomatic and should be followed up by means of periodic radiological examination. Sur gery should be restricted to specific situations. Absolute indications for surgery are spontaneous or trau m atic rupture with hemoperitoneum,intratumoral blee ding and consumptive coagulopathy (Kassabach-Merrit syndrome). In a patient presenting with acute abdo minal pain due to unknown abdominal disease,sponta neous rupture of a hepatic tumor such as a hemangio ma should be considered as a rare differential diagnosis.Marcelo AF Ribeiro Francine Papaiordanou Juliana M Gonalves Eleazar Chaib 2010World Journal of Hepatology2010,2,12:12
3Endoscopy vs surgery in the treatment of early gastric cancer:Systematic review显示文摘AIM: To report a systematic review,establishing the available data to an unpublished 2a strength of evidence,better handling clinical practice.METHODS: A systematic review was performed using MEDLINE,EMBASE,Cochrane,LILACS,Scopus and CINAHL databases. Information of the selected studies was extracted on characteristics of trial participants,inclusion and exclusion criteria,interventions(mainly,mucosal resection and submucosal dissection vs surgical approach) and outcomes(adverse events,different survival rates,mortality,recurrence and complete resection rates). To ascertain the validity of eligible studies,the risk of bias was measured using the Newcastle-Ottawa Quality Assessment Scale. The analysis of the absolute risk of the outcomes was performed using the software Rev Man,by computingrisk differences(RD) of dichotomous variables. Data on RD and 95%CIs for each outcome were calculated using the Mantel-Haenszel test and inconsistency was qualified and reported in χ2 and the Higgins method(I2). Sensitivity analysis was performed when heterogeneity was higher than 50%,a subsequent assay was done and other findings were compiled.RESULTS: Eleven retrospective cohort studies were selected. The included records involved 2654 patients with early gastric cancer that filled the absolute or expanded indications for endoscopic resection. Threeyear survival data were available for six studies(n = 1197). There were no risk differences(RD) after endoscopic and surgical treatment(RD = 0.01,95%CI:-0.02-0.05,P = 0.51). Five-year survival data(n = 2310) showed no difference between the two groups(RD = 0.01,95%CI:-0.01-0.03,P = 0.46). Recurrence data were analized in five studies(1331 patients) and there was no difference between the approaches(RD = 0.01,95%CI:-0.00-0.02,P = 0.09). Adverse event data were identified in eight studies(n = 2439). A significant difference was detected(RD =-0.08,95%CI:-0.10--0.05,P < 0.05),demonstrating better results with endoscopy. Mortality data were obtained in four studies(n = 1107). There was no difference between the groups(RD =-0.01,95%CI:-0.02-0.00,P = 0.22).CONCLUSION: Three-,5-year survival,recurrence and mortality are similar for both groups. Considering complication,endoscopy is better and,analyzing complete resection data,it is worse than surgery.André Kondo Eduardo Guimaraes Hourneaux de Moura Wanderley Marques Bernardo Osmar Kenji Yagi Diogo Turiani Hourneaux de Moura Eduardo Turiani Hourneaux de Moura José Gon?alves Pereira Bravo Kendi Yamazaki Paulo Sakai 2015World Journal of Gastroenterology2015,21,46:12
4Effect of focal laser photocoagulation in eyes with mild to moderate non-proliferative diabetic retinopathy显示文摘AIM:To report the effect of focal laser photocoagulation on both the severity of hard exudates(HEs) and the rate of disease progression in eyes with mild to moderate non-proliferative diabetic retinopathy(NPDR).METHODS: We retrospectively reviewed the medical records of 33 patients(60 eyes) who had been diagnosed with mild to moderate NPDR between January 2006 and December 2012.The patients were divided into 2 groups:Group A(38 eyes in 20 patients treated using focal laser photocoagulation) and Group B(treated without laser photocoagulation).We also reviewed the best corrected visual acuity measurements,and the fundus photographs taken at both baseline and follow-up visits. RESULTS: In Group A,HE severity grade had decreased significantly from baseline to the final visit(P <0.05),but this was not the case in Group B(P =0.662).The cumulative probabilities of retinopathy progression at 5y were 26% in Group A and 30% in Group B.KaplanMeier survival curves showed no significant difference between the groups with regard to retinopathy progression(P =0.805).CONCLUSION: Focal laser photocoagulation reduced the levels of HEs in eyes with mild to moderate NPDR.However,the treatment was not able to decelerate the progression of DR.Seong Hun Jeong Jung Il Han Sung Won Cho Dong Won Lee Chul Gu Kim Tae Gon Lee Jong Woo Kim 2016International Journal of Ophthalmology(English edition)2016,9,10:10
5Quadruple therapy with furazolidone for retreatment in patients with peptic ulcer disease显示文摘AIM: To establish the efficacy and safety of a 7-d therapeutic regimen using omeprazole,bismuth subcitrate,furazolidone and amoxicillin in patients with peptic ulcer disease who had been previously treated with other therapeutic regimens without success.METHODS: Open cohort study which included patients with peptic ulcer who had previously been treated unsuccessfully with one or more eradication regimens.The therapeutic regimen consisted of 20 mg omeprazole,240 mg colloidal bismuth subcitrate,1000 mg amoxicillin,and 200 mg furazolidone,taken twice a day for 7 d.Patients were considered as eradicated when samples taken from the gastric antrum and corpus 12 wk after the end of treatment were negative for Helicobacter pylori (H pylori) (rapid urease test and histology).Safety was determined by the presence of adverse effects.RESULTS: Fifty-one patients were enrolled.The eradication rate was 68.8% (31/45).Adverse effects were reported by 31.4% of the patients,and these were usually considered to be slight or moderate in the majority of the cases.Three patients had to withdraw from the treatment due to the presence of severe adverse effects.CONCLUSION: The association of bismuth,furazolidone,amoxicillin and a proton-pump inhibitor is a valuable alternative for patients who failed to respond to other eradication regimens.It is an effective,cheap and safe option for salvage therapy of positive patients.Guilherme Eduardo Gonalves Felga Fernando Marcuz Silva Ricardo Correa Barbuti Tomás Navarro-Rodriguez Schlioma Zaterka Jaime Natan Eisig 2008World Journal of Gastroenterology2008,14,40:9
6Evidence-based medicine: An update on treatments for peritoneal dialysis-related peritonitis显示文摘Peritonitis continues to be a major complication of peritoneal dialysis(PD), and adequate treatment is crucial for a favorable outcome. There is no consensus regarding the optimal therapeutic regimen, and few prospective controlled studies have been published. The objective of this manuscript is to review the results of PD peritonitis treatment reported in narrative reviews, systematic reviews, and proportional meta-analyses. Two narrative reviews, the only existing systematic review and its update published between 1991 and 2014 were included. In addition, we reported the results of a proportional metaanalysis published by our group. Results from systematic reviews of randomized control trials(RCT) and quasiRCT were not able to identify any optimal antimicrobial treatment, but glycopeptide regimens were more likely to achieve a complete cure than a first generation cephalosporin. Compared to urokinase, simultaneous catheter removal and replacement resulted in better outcomes. Continuous and intermittent IP antibiotic use had similar outcomes. Intraperitoneal antibiotics were superior to intravenous antibiotics in reducing treatment failure. In the proportional meta-analysis of RCTs and the case series, the resolution rate(86%) of ceftazidime plus glycopeptide as initial treatment was significantly higher than first generation cephalosporin plus aminoglycosides(66%) and glycopeptides plus aminoglycosides(75%). Other comparisons of regimens used for either initial treatment or treatment of gram-positive rods or gramnegative rods did not show statistically significant differences. The superiority of a combination of a glycopeptide and a third generation cephalosporin was also reported by a narrative review study published in 1991, which reported an 88% resolution rate.Pasqual Barretti Joo Vitor Pereira Doles Douglas Gonalves Pinotti Regina Paolucci El Dib 2015World Journal of Nephrology2015,4,2:9
7Reliability in endoscopic diagnosis of portal hypertensive gastropathy显示文摘AIM: To analyze reliability among endoscopists in diagnosing portal hypertensive gastropathy (PHG) and to determine which criteria from the most utilized classifications are the most suitable. METHODS: From January to July 2009, in an academic quaternary referral center at Santa Casa of S o Paulo Endoscopy Service, Brazil, we performed this singlecenter prospective study. In this period, we included 100 patients, including 50 sequential patients who had portal hypertension of various etiologies; who were previously diagnosed based on clinical, laboratory and imaging exams; and who presented with esophageal varices. In addition, our study included 50 sequentialpatients who had dyspeptic symptoms and were referred for upper digestive endoscopy without portal hypertension. All subjects underwent upper digestive endoscopy, and the images of the exam were digitally recorded. Five endoscopists with more than 15 years of experience answered an electronic questionnaire, which included endoscopic criteria from the 3 most commonly used Portal Hypertensive Gastropathy classifications (McCormack, NIEC and Baveno) and the presence of elevated or flat antral erosive gastritis. All five endosco- pists were blinded to the patients' clinical information, and all images of varices were deliberately excluded for the analysis. RESULTS: The three most common etiologies of portal hypertension were schistosomiasis (36%), alcoholic cirrhosis (20%) and viral cirrhosis (14%). Of the 50 patients with portal hypertension, 84% were Child A, 12% were Child B, 4% were Child C, 64% exhibited previous variceal bleeding and 66% were previously endoscopic treated. The endoscopic parameters, presence or absence of mosaic-like pattern, red point lesions and cherry-red spots were associated with high inter-observer reliability and high specificity for diagnosing Portal Hypertensive Gastropathy. Sensitivity, specificity and reliability for the diagnosis of PHG (%) were as follows: mosaic-like pattern (100; 92.21; High); fine pink speckling (56; 76.62; Unsatisfactory); superficial reddening (69.57; 66.23; Unsatisfactory); red-point lesions (47.83; 90.91; High); cherry-red spots (39.13; 96.10; High); isolated red marks (43.48; 88.31; High); and confluent red marks (21.74; 100; Unsatisfactory). Antral elevated erosive gastritis exhibited high reliability and high specificity with respect to the presence of portal hypertension (92%) and the diagnosis of portal hypertensive gastropathy (88.31%). CONCLUSION: The most suitable endoscopic criteria for the diagnosis of PHG were mosaic-like pattern, redpoint lesions and cherry-red spots with no subdivisions,which were associated with a high rate of inter-observer reliability.George Fred Soares de Macedo Fabio Gon alves Ferreira Maurício Alves Ribeiro Luiz Arnaldo Szutan Mauricio Saab Assef Lucio Giovanni Battista Rossini 2013World Journal of Gastrointestinal Endoscopy2013,5,7:9
8Non-pharmacological cognitive intervention for aging and dementia:Current perspectives显示文摘In recent years, cognitive difficulties associated with normal aging and dementia have been receiving increased attention from both public and scientific communities. With an increase in overall lifespan, promoting healthy cognition has become a priority and a necessity for minimizing and preventing individual and societal burdens associated with cognitive dysfunctions in the elderly. The general awareness concerning the efficacy of preventive(e.g., lifestyles) and palliative treatment strategies of cognitive impairments, related to either healthy or unhealthy trajectories in cognitive aging, is continuously rising. There are several therapeutic strategies which can be broadly classified as either pharmacological or non-pharmacological/psychosocial. In face of the modest evidence for success of pharmacological treatments, especially for dementia related impairments, psychosocial interventions are progressively considered as a complementary treatment. Despite the relative spread of psychosocial interventions in clinical settings, research in this area is rather scarce with evidence for success of these therapies remaining controversial. In this work we provide an evidence based perspective on cognitive intervention(s) for healthy aging, pre-dementia(mild cognitive impairment), and dementia populations. Current evidence and future directions for improving cognitive functions in the elderly are discussed as well.Jorge Alves Rosana Magalh?es álvaro Machado óscar F Gon?alves Adriana Sampaio Agavni Petrosyan 2013World Journal of Clinical Cases2013,1,8:8
9Efficacy and safety of limited endoscopic sphincterotomy before self-expandable metal stent insertion for malignant biliary obstruction显示文摘AIM To evaluate the safety and efficacy of limited endoscopic sphincterotomy (ES) before placement of selfexpandable metal stent(SEMS).METHODS This was a retrospective analysis of 244 consecutive patients with unresectable malignant biliary obstruction, who underwent placement of SEMSs following limited ES from December 2008 to February 2015. The diagnosis of malignant biliary obstruction and assessment of patient eligibility for the study was established by a combination of clinical findings, laboratory investigations, imaging and pathological results. All patients were monitored in the hospital for at least 24 h following endoscopic retrograde cholangio pancreatography(ERCP). The incidence of immediate or early post-ERCP complications such as post-ERCP pancreatitis(PEP) and bleeding related to limited ES were considered as primary outcomes. Also, characteristics and complications according to the cancer type were classified.RESULTS Among the 244 patients included, the underlying diagnosis was cholangiocarcinoma in 118 patients,pancreatic cancer in 79, and non-pancreatic or nonbiliary malignancies in the remaining 47 patients. Early post-ERCP complications occurred in 9 patients(3.7%), with PEP in 7 patients (2.9%; mild, 6; moderate, 1) and mild bleeding in 2 patients (0.8%). There was no significant association between the incidence of post-ERCP complications and the type of malignancy(cholangiocarcinoma vs pancreatic cancer vs others, P = 0.696) or the type of SEMS used (uncovered vs covered, P = 1.000). Patients who had more than one SEMS placed at the first instance were at a significantly higher risk of post-ERCP complications (one SEMS vs two SEMS, P = 0.031). No other factors were predictive of post-ERCP complications.CONCLUSION Limited ES is feasible and safe, and effectively facilitates the placement of SEMS, without any significant risk of PEP or severe bleeding.Hyeong Seok Nam Dae Hwan Kang Hyung Wook Kim Cheol Woong Choi Su Bum Park Su Jin Kim Dae Gon Ryu 2017World Journal of Gastroenterology2017,23,9:7
10Recent updates and current issues of sentinel node navigation surgery for early gastric cancer显示文摘With the increase in the incidence of early gastric cancer(EGC),several endoscopic and laparoscopic approaches,such as endoscopic submucosal dissection and function-preserving gastrectomy,have been accepted as standard treatments.Sentinel node navigation surgery(SNNS)is an ideal surgical option for preservation of most parts of the stomach and consequent maintenance of normal gastric function to improve quality of life in patients with EGC.Although many previous studies and clinical trials have demonstrated the safety and feasibility of the sentinel node concept in gastric cancer,the clinical application of SNNS is debatable.Several issues regarding technical standardization and oncological safety need to be resolved.Recently several studies to resolve these problems are being actively performed,and SNNS might be an important surgical option in the treatment of gastric cancer in the future.Sung Gon Kim Bang Wool Eom Hong Man Yoon Chan Gyoo Kim Myeong-Cherl Kook Young-Woo Kim Keun Won Ryu 2021Chinese Journal of Cancer Research2021,33,2:7
11Pathophysiology of cystic fibrosis and drugs used in associated digestive tract diseases显示文摘Cystic fibrosis(CF)causes chronic infections in the respiratory tract and alters the digestive tract.This paper reviews the most important aspects of drug treatment and changes in the digestive tract of patients with CF.This is a review of the literature,emphasizing the discoveries made within the last 15 years by analyzing scientific papers published in journals indexed in the Scientific Electronic Library Online,Sciences Information,United States National Library of Medicine and Medical Literature Analysis and Retrieval System Online databases,both in English and Portuguese,using the key words:cystic fibrosis,medication,therapeutic,absorption,digestion.Randomized,observational,experimental,and epidemiological clinical studies were selected,among others,with statistical significance of 5%.This review evaluates the changes found in the digestive tract of CF patients including pancreatic insufficiency,constipation and liver diseases.Changes in nutritional status are also described.Clinical treatment,nutritional supplementation and drug management were classified in this review as essential to the quality of life of CF patients,and became available through public policies for monitoring and treating CF.The information gathered on CF and a multi professional approach to the disease is essential in the treatment of these patients.Adriana Haack Giselle Gonalves Arago Maria Rita Carvalho Garbi Novaes 2013World Journal of Gastroenterology2013,19,46:7
12Magnesium citrate with a single dose of sodium phosphate for colonoscopy bowel preparation显示文摘AIM:To evaluate the efficacy and acceptability of magnesium citrate and a single dose of oral sodium phosphate(45 mL) solution for morning colonoscopy bowel preparation. METHODS:A total of 159 patients were randomly assigned to receive two split doses of 90 mg of sodium phosphate(GroupⅠ,n=79) or magnesium citrate(250 mL,the day before the procedure) followed by 45 mL of sodium phosphate(the day of procedure,GroupⅡ,n= 80) .The quality of bowel cleansing and the acceptability of each regimen were compared,including the satisfaction,taste,willing to repeat and adverse effects of each regimen. RESULTS:The quality of bowel cleansing of GroupⅡ was as good as that of GroupⅠ(An Aronchick scale score of good or excellent:70.9%vs 81.0%,respectively,P=0.34;the Ottawa system score:4.4±2.6 vs 3.8 ±3.0,respectively,P=0.76) .There was no statisticallysignificant difference between both groups with regard to acceptability,including the satisfaction,taste and willingness to repeat the regimen.A significantly greater number of older patients(over 65 years old) in Group Ⅱgraded the overall satisfaction as satisfactory(48.1% vs 78.1%,respectively;GroupⅠvs GroupⅡ,P=0.01) . There were no significant adverse reactions. CONCLUSION:Magnesium citrate and a single dose of sodium phosphate was as effective and tolerable as the conventional sodium phosphate regimen and is a satisfactory option.Yong Sung Choi Jung Pil Suh Jong Kyu Kim In Taek Lee Eui Gon Youk Doo Seok Lee Do Sun Kim Doo Han Lee 2011World Journal of Gastroenterology2011,17,2:7
13Flexible electronics based on one-dimensional and two-dimensional hybrid nanomaterials显示文摘Research on flexible or wearable electronics has been grown remarkably due to the advent of nanomaterials,such as metal nanowires,graphene,or transition metal dichalcogenides.Although each nanomaterial has mechanical and electrical characteristics that can be applied into flexible electronics,the limitations of each nanomaterial are also clear.In order to overcome the limitations of these nanomaterials,research on the hybrid structures of nanomaterials has been extensively conducted.In this study,we introduce the properties of one-dimensional nanomaterials,twodimensional nanomaterials,and their hybrid nanomaterials.And then,we provide information concerning various flexible electronics based on these nanomaterials.Jihun Park Jae Chul Hwang Gon Guk Kim Jang-Ung Park 2020InfoMat2020,2,1:7
14PD-1 blockade-unresponsive human tumor-infiltrating CD8^(+)T cells are marked by loss of CD28 expression and rescued by IL-15显示文摘Blockade of programmed death-1(PD-1)reinvigorates exhausted CD8^(+)T cells,resulting in tumor regression in cancer patients.Recently,reinvigoration of exhausted CD8^(+)T cells following PD-1 blockade was shown to be CD28-dependent in mouse models.Herein,we examined the role of CD28 in anti-PD-1 antibody-induced human T cell reinvigoration using tumor-infiltrating CD8^(+)T cells(CD8^(+)TILs)obtained from non-small-cell lung cancer patients.Single-cell analysis demonstrated a distinct expression pattern of CD28 between mouse and human CD8^(+)TILs.Furthermore,we found that human CD28^(+)CD8^(+)but not CD28^(–)CD8^(+)TILs responded to PD-1 blockade irrespective of B7/CD28 blockade,indicating that CD28 costimulation in human CD8^(+)TILs is dispensable for PD-1 blockade-induced reinvigoration and that loss of CD28 expression serves as a marker of anti-PD-1 antibody-unresponsive CD8^(+)TILs.Transcriptionally and phenotypically,PD-1 blockade-unresponsive human CD28^(–)PD-1^(+)CD8^(+)TILs exhibited characteristics of terminally exhausted CD8^(+)T cells with low TCF1 expression.Notably,CD28^(–)PD-1^(+)CD8^(+)TILs had preserved machinery to respond to IL-15,and IL-15 treatment enhanced the proliferation of CD28^(–)PD-1^(+)CD8^(+)TILs as well as CD28^(+)PD-1^(+)CD8^(+)TILs.Taken together,these results show that loss of CD28 expression is a marker of PD-1 blockade-unresponsive human CD8^(+)TILs with a TCF1–signature and provide mechanistic insights into combining IL-15 with anti-PD-1 antibodies.Kyung Hwan Kim Hong Kwan Kim Hyung-Don Kim Chang Gon Kim Hoyoung Lee Ji Won Han Seong Jin Choi Seongju Jeong Minwoo Jeon Hyunglae Kim Jiae Koh Bo Mi Ku Su-Hyung Park Myung-Ju Ahn Eui-Cheol Shin 2021Cellular & Molecular Immunology2021,18,2:6
15Impaired T-cell differentiation in diabetic foot ulceration显示文摘Foot ulceration is one of the most debilitating complications associated with diabetes,but its cause remains poorly understood.Several studies have been undertaken to understand healing kinetics or find possible therapies to enhance healing.However,few studies have been directed at understanding the immunological alterations that could influence wound healing in diabetes.In this study,we analysed the T-cell receptor(TCR)repertoire diversity in TCR-αβ^(+)T cells.We also analysed the distribution and phenotype of T cells obtained from the peripheral blood of healthy controls and diabetic individuals with or without foot ulcers.Our results showed that diabetic individuals,especially those with foot ulcers,have a significantly lower naive T-cell number and a poorer TCR-Vβrepertoire diversity.We also showed that the reduced TCR-Vβrepertoire diversity in diabetic individuals was mainly owing to the accumulation of effector T cells,the major source of tumour necrosis factor-αproduction,which was even more pronounced in patients with acute foot ulceration.Moreover,the expression of several inflammatory chemokine receptors was significantly reduced in diabetic patients.In conclusion,effector T-cell accumulation and TCR repertoire diversity reduction appear to precede the development of foot ulcers.This finding may open new immunological therapeutic possibilities and provide a new prognostic tool in diabetic wound care.João Moura João Rodrigues Marta Gonçalves Cláudia Amaral Margarida Lima Eugénia Carvalho 2017Cellular & Molecular Immunology2017,14,9:6
16Is endoscopic papillary large balloon dilatation without endoscopic sphincterotomy effective?显示文摘AIM: To evaluate the safety and efficacy of endoscopic papillary large balloon dilatation(EPLBD) without endoscopic sphincterotomy in a prospective study.METHODS: From July 2011 to August 2013, we performed EPLBD on 41 patients with nae papillae prospectively. For sphincteroplasty of EPLBD,endoscopic sphincterotomy(EST) was not performed,and balloon diameter selection was based on the distal common bile duct diameter. The balloon was inflated to the desired pressure. If the balloon waist did not disappear, and the desired pressure was satisfied, we judged the dilatation as complete. We used a retrieval balloon catheter or mechanical lithotripter(ML) to remove stones and assessed the rates of complete stone removal, number of sessions, use of ML and adverse events. Furthermore, we compared the presence or absence of balloon waist disappearance with clinical characteristics and endoscopic outcome.RESULTS: The mean diameters of the distal and maximum common bile duct were 13.5 ± 2.4 mm and16.4 ± 3.1 mm, respectively. The mean maximum transverse-diameter of the stones was 13.4 ± 3.4mm, and the mean number of stones was 3.0 ± 2.4.Complete stone removal was achieved in 97.5%(40/41)of cases, and ML was used in 12.2%(5/41) of cases.The mean number of sessions required was 1.2 ± 0.62.Pancreatitis developed in two patients and perforation in one. The rate of balloon waist disappearance was73.1%(30/41). No significant differences were noted in procedure time, rate of complete stone removal(100% vs 100%), number of sessions(1.1 vs 1.3, P= 0.22), application of ML(13% vs 9%, P = 0.71),or occurrence of pancreatitis(3.3% vs 9.1%, P =0.45) between cases with and without balloon waist disappearance.CONCLUSION: EST before sphincteroplasty may be unnecessary in EPLBD. Further investigations are needed to verify the relationship between the presence or absence of balloon waist disappearance.Shigefumi Omuta Iruru Maetani Michihiro Saito Hiroaki Shigoka Katsushige Gon Junya Tokuhisa Mieko Naruki 2015World Journal of Gastroenterology2015,21,23:5
17Low temperature,IBA concentrations and optimal time for adventitious rooting of Eucalyptus benthamii mini-cuttings显示文摘Eucalyptus benthamii is a forest species of economic interest that has difficulty with seed production and also is considered to have difficulty with adventitious rooting using propagation techniques,such as cutting or mini-cutting.We aimed to assess the adventitious rooting percentage under different storage times in low temperatures and at various IBA(indole-3-butyric acid) concentrations to determine the optimal time of permanence for rooting Eucalyptus benthamii minicuttings in a greenhouse.Shoots collected from mini-stumps cultivated in a semi-hydroponic system were used to obtain the mini-cuttings.For the first experiment,the mini-cuttings were stored at 4℃ for 0(immediate planting),24,48,72,96 and 120 h.The second experiment evaluated the rooting dynamic to determine the optimal time of permanence for minicuttings in a greenhouse.The basal region of the mini-cutting was treated with various IBA solutions:0(free of IBA),1,000,2,000,3,000 and 4,000 mg·L-1.Every seven days(0(immediate planting),7,14,21 and 28 days),destructive sampling of the mini-cuttings was performed to evaluate the histology of the adventitious rooting.Eucalyptus benthamii minicuttings should be rooted immediately after the collection of the shoots.The 2,000 mg·L-1 IBA concentration induced a greater speed and percentage of adventitious rooting,and an interval of 35 to 42 days was indicated for permanence of the mini-cuttings in the greenhouse.Exposure to low temperature induced adventitious root formation with diffuse vascular connections.Gilvano Ebling Brondani Francisco JoséBenedini Baccarin Heron Wilhelmus de Wit Ondas JoséLuiz Stape Antonio Natal Gonçalves Marcilio de Almeida 2012Journal of Forestry Research2012,23,4:5
18河套灌区畦-沟分灌水分利用效率及节水效果试验研究显示文摘针对目前河套灌区小麦/玉米间作同畦栽培情况下灌溉水浪费的突出问题,文中以当地常规的平畦灌溉方式作为对照,对小麦/玉米间作系统设计了小麦采用平畦灌溉,玉米采用垄沟灌溉的畦-沟分灌法,通过对比田间灌溉参数,灌水指标和水分利用效率来评价其灌溉节水效果。结果表明:畦-沟分灌优化了畦田灌溉参数,同平畦灌溉相比,小麦条带和玉米条带的单宽(沟)流量增大2-4倍,明显提高水流推进速率;水流推进曲线和水流消退曲线更加平行,优化了灌溉参数;小麦条带和玉米条带的灌水效率、灌溉均匀度分别提高30%、16%和26%、12%,水分利用效率从目前水平1.18kg/m3提高到1.66kg/m3,建议河套灌区在小麦/玉米间作的不同种植带打起地埂,根据不同作物对水分的需求进行合理的畦-沟分灌。苗庆丰 史海滨 李瑞平 倪东宁 José Manuel Gonalves 2015干旱区资源与环境2015,29,10:5
19Upper gastrointestinal bleeding risk scores: Who, when andwhy?显示文摘Upper gastrointestinal bleeding(UGIB) remains a significant cause of hospital admission. In order to stratify patients according to the risk of the compli-cations, such as rebleeding or death, and to predict the need of clinical intervention, several risk scores have been proposed and their use consistently recommended by international guidelines. The use of risk scoring systems in early assessment of patients suffering from UGIB may be useful to distinguish high-risks patients, who may need clinical intervention and hospitalization, from low risk patients with a lower chance of developing complications, in which management as outpatients can be considered. Although several scores have been published and validated for predicting different outcomes, the most frequently cited ones are the Rockall score and the Glasgow Blatchford score(GBS). While Rockall score, which incorporates clinical and endoscopic variables, has been validated to predict mortality, the GBS, which is based on clinical and laboratorial parameters, has been studied to predict the need of clinical intervention. Despite the advantages previously reported, their use in clinical decisions is still limited. This review describes the different risk scores used in the UGIB setting, highlights the most important research, explains why and when their use may be helpful, reflects on the problems that remain unresolved and guides future research with practical impact.Sara Monteiro Tiago Cúrdia Gonçalves Joana Magalhães JoséCotter 2016World Journal of Gastrointestinal Pathophysiology2016,7,1:5
20Imbalance in T-cell differentiation as a biomarker of chronic diabetic foot ulceration显示文摘Diabetes is a growing epidemic due to the systematic increase in overweight and obesity,and chronic diabetic foot ulcers(DFUs)are the most debilitating and costly complication of diabetes.Prevention is still essential for DFU care,but early detection is limited because we do not have a good DFU biomarker.Here,we report the preliminary results of a large longitudinal study to test the effectiveness of the use of T-cell phenotype and TCR repertoire diversity as DFU biomarkers.Our results show that the ratio of effector/naïve T-cells and the number of TCR expansions are valuable biomarkers of DFU prognosis.Joao Moura Joao Rodrigues Marta Gonçalves Claudia Amaral Margarida Lima Eugenia Carvalho 2019Cellular & Molecular Immunology2019,16,10:4
