3Subclinical abnormal glucose tolerance is a predictor of death in liver cirrhosis显示文摘AIM:To determine if subclinical abnormal glucose tolerance(SAGT)has influence on survival of non-diabetic patients with liver cirrhosis.METHODS:In total,100 patients with compensatedliver cirrhosis and normal fasting plasma glucose were included.Fasting plasma insulin(FPI)levels were measured,and oral glucose tolerance test(OGTT)was performed.According to OGTT results two groups of patients were formed:those with normal glucose tolerance(NGT)and those with SAGT.Patients were followed every three months.The mean follow-up was932 d(range of 180-1925).Survival was analyzed by the Kaplan-Meyer method,and predictive factors of death were analyzed using the Cox proportional hazard regression model.RESULTS:Of the included patients,30 showed NGT and70 SAGT.Groups were significantly different only in age,INR,FPI and HOMA2-IR.Patients with SAGT showed lower 5-year cumulated survival than NGT patients(31.7%vs 71.6%,P=0.02).Differences in survival were significant only after 3 years of follow-up.SAGT,Child-Pugh B,and high Child-Pugh and Model for EndStage Liver Disease(MELD)scores were independent predictors of death.The causes of death in 90.3%of cases were due to complications related to liver disease.CONCLUSION:SAGT was associated with lower survival.SAGT,Child-Pugh B,and high Child-Pugh and MELD scores were independent negative predictors of survival.Diego García-Compeán Joel Omar Jáquez-Quintana Fernando Javier Lavalle-González José Alberto González-González Linda Elsa Mu?oz-Espinosa Jesús Zacarías Villarreal-PérezEndocrinology Service and Department of Internal Medicine University Hospital 'Dr. José E.

4脑缺血后N-myc下游调控基因2保护血脑屏障完整性显示文摘脑缺血后血脑屏障(BBB)的破坏与外周细胞向脑内浸润、病孔损形成与进展、以及临床病程恶化密切相关。目前BBB完整性的调控机制,尤其是在永久性缺血后的调控机制尚未明确。本研究使用小鼠永久性脑缺血模型进行相关研究,结果显示,星形胶质细胞N-myc下游调控基因2(NDRG2)可能是缺血性脑卒中后BBB通透性的调控分子,该分子与分化和应激相关。免疫组化显示,在永久性大脑中动脉闭塞(MCAO)后,NDRG2在星形胶质细胞中的表达显著增加。敲除NDRG2基因,脑梗死体积增加,免疫细胞在缺血同侧大脑半球积聚增加。MCAO后,NDRG2基因敲除小鼠缺血侧皮质的缺血灶内及灶周血管周围区域内的血清蛋白(包括纤维蛋白原和免疫球蛋白)的外渗增强此之,MCAO后NDRG2基因敲除小鼠体内基质金属蛋白酶(MMPs)的表达也显著增加。在细胞培养中,NDRG2-/-星形胶质细胞中MMP-3的表达和分泌增加,这种增加可被腺病毒介导的NDRG2再表达所逆转。综上所述,脑缺血后,星形胶质细胞内的NDRG2可能通过调节MMP的表达,而在BBB通透性的调节和免疫细胞浸润中起到重要作用。Takarada-Iemata M Yoshikawa A Ta HM Okitani N Nishiuchi T Aida Y Kamide T Hattori T Ishii H Tamatani T Le TM Roboon J Kitao Y Matsuyama T Nakada M Hori O 聂昊 2018神经损伤与功能重建2018,13,4:4
5Clinical classification of symptomatic heterotopic pancreas of the stomach and duodenum:A case series and systematic literature review显示文摘BACKGROUND Heterotopic pancreas(HP)is an aberrant anatomic malformation that occurs most commonly in the upper gastrointestinal tract.While the majority of heterotopic pancreatic lesions are asymptomatic,many manifest severe clinical symptoms which require surgical or endoscopic intervention.Understanding of the clinical manifestations and symptoms of HP is limited due to the lack of large volume studies in the literature.The purpose of this study is to review symptomatic cases at a single center and compare these to a systematic review of the literature in order to characterize common clinical manifestations and treatment of this disease.AIM To classify the common clinical manifestations of heterotopic pancreas.METHODS A retrospective review was conducted of pathologic samples containing heterotopic pancreas from 2000-2018.Review was limited to HP of the upper gastrointestinal tract due to the frequency of presentation in this location.Symptomatic patients were identified from review of the medical records and clinical symptoms were tabulated.These were compared to a systematic review of the literature utilizing Pub Med and Embase searches for papers pertaining to heterotopic pancreas.Publications describing symptomatic presentation of HP were selected for review.Information including demographics,symptoms,presentation and treatment were compiled and analyzed.RESULTS Twenty-nine patient were identified with HP at a single center,with six of these identified has having clinical symptoms.Clinical manifestations included,gastrointestinal bleeding,gastric ulceration with/without perforation,pancreatitis,and gastric outlet obstruction.Systemic review of the literature yielded 232 publications detailing symptomatic cases with only 20 studies describing ten or more patients.Single and multi-patient studies were combined to form a cohort of 934 symptomatic patients.The majority of patients presented with abdominal pain(67%)combined with one of the following clinical categories:(1)Dyspepsia,(n=445,48%);(2)Pancreatitis(n=260,28%);(3)Gastrointestinal bleeding(n=80,9%);and(4)Gastric outlet obstruction(n=80,9%).The majority of cases(n=832,90%)underwent surgical or endoscopic resection with 85%reporting resolution or improvement in their symptoms.CONCLUSION Heterotopic pancreas can cause significant clinical symptoms in the upper gastrointestinal tract.Better understanding and classification of this disease may result in more accurate identification and treatment of this malformation.Michael T Le Compte Brandon Mason Keenan J Robbins Motoyo Yano Deyali Chatterjee Ryan C Fields Steven M Strasberg William G Hawkins 2022World Journal of Gastroenterology2022,28,14:3

8Competition between fusion-evaporation and multifragmentation in central collisions in ^(58)Ni+^(48)Ca at 25A MeV显示文摘The experimental data concerning the58Ni+48Ca reaction at Elab(Ni)=25A MeV,collected by using the CHIMERA 4π device,have been analyzed in order to investigate the competition among different reaction mechanisms for central collisions in the Fermi energy domain.As a main criterion for centrality selection we have chosen the flow angle(flow) method,making an event-by-event analysis that considers the shape of events,as it is determined by the eigenvectors of the experimental kinetic-energy tensor.For the selected central events(flow >60°) some global variables,good to characterize the pattern of central collisions have been constructed.The main features of the reaction products were explored by using different constraints on some of the relevant observables,like mass and velocity distributions and their correlations.Much emphasis was devoted,for central collisions,to the competition between fusion-evaporation processes with subsequent identification of a heavy residue and a possible multifragmentation mechanism of a well defined(if any) transient nuclear system.Dynamical evolution of the system and pre-equilibrium emission were taken into account by simulating the reactions in the framework of transport theories.Different approaches have been envisaged(dynamical stochastic BNV calculations + sequential SIMON code,QMD,CoMD,etc.).Preliminary comparison of the experimental data with BNV calculations shows reasonable agreement with the assumption of sequential multifragmentation emission in the mass region of IMFs close to the heavy residues.Possible deviations from sequential processes were found for those IMFs in the region of masses intermediate between the mass of heavy residues and the mass of light IMFs.Further simulations are in progress.The experimental analysis will be enriched also by information obtained inspecting the IMF-IMF correlation function,in order to elucidated the nature of space-time decay property of the emitting source associated with events having the largest IMF multiplicity.FRANCALANZA L ABBONDANNO U AMORINI F BARLINI S BINI M BOUGAULT R BRUNO M CARDELLA G CASINI G AGOSTINO M D' De FILIPPO V De SANCTIS J GERACI E GIUSSANI A GRAMEGNA F GUIOT B KRAVCHUK V La GUIDARA E LANZALONE G Le NEINDRE N MAIOLINO C MARINI P MORELLI L OLMI A PAGANO A PAPA M PIANTELLI S PIRRONE S POLITI G POGGI G PORTO F RUSSOTTO P RIZZO F VANNINI G VANNUCCI L 2013Nuclear Science and Techniques2013,24,5:2
