1美国国立老化研究所与阿尔茨海默病协会诊断指南写作组:对阿尔茨海默病诊断指南的推荐和介绍显示文摘背景:尽管早在1984年就制定了阿尔茨海默病(AD)的临床诊断标准,但是近年来的研究进展从未被补充到诊断标准中。因此,制定一个新的临床诊断标准已经成为大家的共识。方法:在2009年,美国国立老化研究所与AD协会组织了一系列圆桌会议,目的是讨论用于AD临床和科研的诊断标准的修订路线。经讨论后决定组建3个独立的工作组,分别制定AD在3个不同疾病发展阶段的诊断标准,即痴呆阶段、有症状的痴呆前期、无症状的临床前期。结果:修订版AD诊断标准与1984年版诊断标准有两处显著的差别:加入了能提示潜在疾病状态的生物标志物的内容;制定了不同认知障碍阶段的诊断标准。其中,3个工作组一致认为,生物标志物的诊断价值还需要更多研究来规范和验证。另外,修订版中还明确区分了仅存在AD病理生理改变(语义性)和仅存在AD临床表现(概念性)两种诊断的差别,该内容在1984年版中没有体现。结论:修订版AD诊断标准中共产生了3个文件,其中,核心的关于AD的痴呆阶段诊断标准和可归于AD的MCI阶段标准推荐用于临床诊断,而临床前期诊断标准仅推荐用于研究使用。Jack CR Jr Albert MS Knopman DS McKhann GM Sperling RA Carrillo MC Thies B Phelps CH 贾建平(译) 李丹(译) 閵芳菊(译) 陆璐(译) 张逸驰(译) 黄丽(译) 2012中华神经科杂志2012,45,5:26
2美国国立老化研究所与阿尔茨海默病协会诊断指南写作组:阿尔茨海默病临床前阶段的定义显示文摘阿尔茨海默病(AD)的病理生理过程在痴呆诊断的多年前就开始了。这一长期的AD“临床前”阶段是治疗干预的关键机会,但需进一步阐明AD的病理级联过程和临床症状出现之间的联系。美国国立老化研究所和AD协会召集了一个国际工作组对AD生物标志物、流行病学和神经心理学的证据进行综述并提出建议,以确定能够预测由“正常”认知到轻度认知功能障碍(MCI)及AD痴呆的最佳预测指标。根据目前已有的主要科学证据,我们提出了一个概念性的框架和用于操作的研究标准,以通过纵向临床研究来验证和改进这些模型。这些建议仅用于研究目的,目前不涉及临床应用。我们希望这些建议能提供一个共识,以推进临床前AD的研究,最终推动更早期治疗干预的进展,使得一些疾病减缓药物的疗效发挥最大。Sperling RA Aisen PS Beckett LA Bennett DA Craft S Fagan AM Iwatsubo T Jack CR Jr Kaye J Montine TJ Park DC Reiman EM Rowe CC Siemers E Stern Y Yaffe K Carrillo MC Thies B Morrison-Bogorad M Wagster MV Phelps CH 贾建平(译) 郭起浩(译) 黄丽(译) 陆璐(译) 张逸驰(译) 邢怡(译) 2012中华神经科杂志2012,45,5:22
3Effect of preoperative FOLFOX chemotherapy on CCL20/CCR6 expression in colorectal liver metastases显示文摘AIM:To evaluate the influence of preoperative FOLFOX chemotherapy on CCL20/CCR6 expression in liver metastases of stage Ⅳ colorectal cancer(CRC) patients.METHODS:Using Real Time-PCR,enzyme-linked immunosorbent assay,Western Blots and immunohistochemistry,we have analyzed the expression of CCL20,CCR6 and proliferation marker Ki-67 in colorectal liver metastasis(CRLM) specimens from stage Ⅳ CRC patients who received preoperative FOLFOX chemotherapy(n = 53) and in patients who did not receive FOLFOX chemotherapy prior to liver surgery(n = 29).RESULTS:Of the 53 patients who received FOLFOX,time to liver surgery was ≤ 1 mo in 14 patients,≤ 1 year in 22 patients and > 1 year in 17 patients,respectively.In addition,we investigated the proliferation rate of CRC cells in liver metastases in the different patient groups.Both CCL20 and CCR6 mRNA and protein expression levels were significantly increased in patients who received preoperative FOLFOX chemotherapy ≤ 12 mo before liver surgery(P < 0.001) in comparison to patients who did not undergo FOLFOX treatment.Further,proliferation of CRLM cells as measured by Ki-67 was increased in patients who underwent FOLFOX treatment.CCL20 and CCR6 expression levels were significantly increased in CRLM patients who had undergone preoperative FOLFOX chemotherapy.CONCLUSION:This chemokine/receptor up-regulation could lead to increased proliferation/migration through an autocrine mechanism which might be used by surviving metastatic cells to escape cell death caused by FOLFOX.Claudia Rubie Vilma Oliveira Frick Pirus Ghadjar Mathias Wagner Christoph Justinger Stefan Graeber Jens Sperling Otto Kollmar Martin K Schilling 2011World Journal of Gastroenterology2011,17,26:5
4Relevance of low viral load in haemodialysed patients with chronic hepatitis C virus infection显示文摘AIM: To identify predictors of sustained virological response in hemodialysed patients treated by PEGinterferon α for chronic hepatitis C, genotype 1.METHODS: The sustained virological response(SVR) rate, IL28 B genotype, IFNL4 genotype, initial viral load(IVL) and other pretreatment variables in 39 endstage renal disease patients(ESRD) on maintenance haemodialysis(HD) infected with hepatitis C virus(HCV), genotype 1b, were compared with a control group of 109 patients with normal kidney function treated within the same period. All the patients were treatment nave and had well compensated liver disease. The ESRD patients received 135 μg of PEGylated interferon α-2a(Peg IFN-α) weekly and a reduced dose of ribavirin(RBV) was administered to 23/39 patients with an initial haemoglobin level > 10 g/d L. Control group patients were given standard doses of Peg IFN-α and RBV. SVR was assessed as HCV RNA negativity 24 wk post-treatment. A t-test or ANOVA were used for comparisons of the means and a χ2 testcompared the frequencies.Logistic regression was used to determine significant predictors of SVR.Cutoff values for continuous variables were obtained from Receiver Operating Characteristic analysis.RESULTS:The distribution of IL28B rs12979860 CC,CT and TT genotypes in the ESRD group was 28.2%,64.1%and 7.7%,respectively,and 19.3%,62.4%and18.3%in the controls.The IFNL4 genotype was in almost absolute linkage disequlibrium with IL28B.The proportion of patients with a low IVL(<600000 IU/m L)was significantly higher in the ESRD group than in the controls(28/39,71.8%vs 51/109,46.8%,P=0.009),as was the proportion of patients with low IVL in IL28B CC carriers compared with non-CC carriers in the ESRD group(10/11,90.9%vs 18/28,64.3%,P=0.0035).This difference was not found in the controls(7/22,31.8%vs 44/87,50.6%,P=0.9).The overall SVR rate was 64.1%(25/39)in the ESRD group and 50.5%(55/109)in the control group(P=0.19).11/11(100%)and 19/22(86.4%)IL28B CC patients achieved SVR in the ESRD and control groups,respectively.A statistically significant association between SVR and IL28B and IFNL4 variants was found in both groups.The ESRD patients who achieved SVR showed the lowest IVL[median 21000,interquartile range(IQR):6000-23000IU/m L],compared with ESRD individuals without SVR(1680000,IQR:481000-6880000,P=0.001),controls with SVR(387000,IQR:111000-1253000)and controls without SVR(905000,IQR:451000-3020000).In ESRD,an IVL<600000 IU/m L was strongly associated with SVR:24/28(85.7%)patients who achieved SVR had viraemia below this threshold.CONCLUSION:Haemodialysis decreases the viral load,especially in IL28B CC genotype carriers.A low IVL was the strongest predictor of SVR in ESRD patients identified in multivariate analysis.Jan Sperl Sona Frankova Renata Senkerikova Magdalena Neroldova Vaclav Hejda Miroslava Volfova Dusan Merta Ondrej Viklicky Julius Spicak Milan Jirsa 2015World Journal of Gastroenterology2015,21,18:2

6Experimental and numerical study on energy dissipation in freely cooling granular gases under microgravity显示文摘Energy dissipation is one of the most important properties of granular gas, which makes its behavior different from that of molecular gas. In this work we report our investigations on the freely-cooling evolution of granular gas under microgravity in a drop tower experiment, and also conduct the molecular dynamics(MD) simulation for comparison.While our experimental and simulation results support Haff's law that the kinetic energy dissipates with time t as E(t) ~(1 + t/τ)^(-2), we modify τ by taking into account the friction dissipation during collisions, and study the effects of number density and particle size on the collision frequency. From the standard deviation of the measured velocity distributions we also verify the energy dissipation law, which is in agreement with Haff's kinetic energy dissipation.王文广 厚美瑛 陈科 虞培东 Matthias Sperl 2018Chinese Physics B2018,27,8:2
