1最新AD研究用诊断标准:IWG-2标准显示文摘在过去的8年中,国际工作组织(IWG)和美国国立老化研究院-阿尔茨海默协会(NIA-AA)建立了阿尔茨海默病(AD)诊断标准,它能更好地定义AD的临床表型,整合了生物标记物于诊断流程中,并覆盖了疾病的全程。本意见书充分地权衡了IWG标准的优缺点,建议改进诊断框架。依据这些改进,AD的诊断变得简单,只要有恰当的AD临床表型(典型或不典型)和与AD的病理相一致的病理生理学生物标志物出现。我们认为疾病的下游的定位性生物标志,如容积性磁共振成像(MRI)和氟脱氧葡萄糖-正电子发射型计算机断层成像(FDG-PET)等,适合更好地测量和监测疾病过程。本文还详述了非典型性AD、混合性AD和AD临床前期的特异诊断标准。陈刚 曹雯炜 俞羚 糜建华 Dubois B Feldman HH Jacova C Hampel H Molinuevo JL Blennow K DeK osky ST Gauthier S Selkoe D Bateman R Cappa S Crutch S Engelborghs S Frisoni GB Fox NC Galasko D Habert MO Jicha GA Nordberg A Pasquier F Rabinovici G Robert P Rowe C Salloway S Sarazin M Epelbaum S de Souza LC Vellas B Visser PJ Schneider L Stern Y Scheltens P Cummings JL 2014神经病学与神经康复学杂志2014,11,3:31
2臂间血压差异与冠状动脉粥样硬化的相关性显示文摘臂间血压差异(interm-arm blood pressure difference,IABPD)是较易获得的无创参数,从20世纪早期开始,临床医生已开始研究其用途[1]。右臂血压通常高于左臂血压,因为与右侧锁骨下动脉相比,左侧锁骨下动脉来源于主动脉,形成一个锐角,导致紊流,降低血流和血压,造成IABPD。英国国家卫生与临床研究所推出的新高血压临床指南建议,IABPD〈10mm Hg(1mm Hg=0.133kPa)可考虑为正常。Park SJ Son JW Park SM Choi HH Hong KS 2017中华高血压杂志2017,25,8:18

4An electron microscopic-cytochemical localization of plasma membrane Ca^(2+)-ATPase activity in poplar apical bud cells during the induction of dormancy by short-day photoperiods显示文摘Plasma membrane (PM) Ca2+-ATPase activity in poplar apical bud meristematic cells during short-day (SD)-induced dormancy development was examined by a cerium precipitation EM-cytochemical method. Ca2+-ATPase activity, indicated by the status of cerium phosphate precipitated grains, was localized mainly on the interior face (cytoplasmic side) of the PM when plants were grown under long days and reached a deep dormancy. A few reaction products were also observed on the nuclear envelope.When plant buds were developing dormancy after 28 to 42 d of SD exposure, almost no reaction products were present on the interior face of the PM. In contrast, a large number of cerium phosphate precipitated grains were distributed on the exterior face of the PM. After 70 d of SD exposure, when buds had developed a deep dormancy, the reaction products of Ca2+-ATPase activity again appeared on the interior face of the PM. The results seemed suggesting that two kinds of Ca2+-ATPases may be present on the PM during the SD-induced dormancy in poplar.One is the Ca2+-punlping ATPase, which is located on the interior face of the PM, for maintaining and restoring the Ca2+homeostasis. The other might be an ecto-Ca2+-ATPase, which is located on the exterior face of the PM, for the exocytosis of cell wall materials as suggested by the fact of the cell wall thickening during the dormancy developlnent in poplar.JIAN LING CHENG JI HONG LI PAUL H LI TONY HH CHEN(Tel: 1612 624 1757 Fax: +1612 624 4941 E-mail: lixxx008@tc.umn.edu)(1Laboratory of Plant Hardiness, Department of Horticultural Science and Plant Biological Sciences Program, University of Minnesota, 2000Cell Research2000,10,2:9

7Species distribution of polymeric aluminium ferrum——timed complexation colorimetric analysis method of Al-Fe-Ferron显示文摘The effects of the colorimetric buffer solutions were investigated while the two colorimetric reactions of A1 ferron complex and Fe ferron complex occurred individually, and the effects of the testing wavelength and the pH of the solutions were also investigated. A timed complexation colorimetric analysis method of A1 Fe ferron in view of the total concentration of {A1+Fe} was then established to determine the species distribution of polymeric Al Fe. The testing wavelength was recommended at 362 nm and the testing pH value was 5. With a comparison of the ratios of n Al / n Fe , the standard adsorption curves of the polymeric Al Fe solutions were derived from the experimental results. Furthermore, the solutions’composition were various in both the molar n Al / n Fe ratios, i.e. 0/0, 5/5, 9/1 and 0/10, and the concentrations associated with the total [A1+Fe] which ranged from 10 -5 to 10 -4 mol/L.Hu, YY Tu, CQ Wu, HH 2001Journal of Environmental Sciences2001,13,4:8

10Risks of rapid decline renal function in patients with type 2 diabetes显示文摘Progressive rising population of diabetes and related nephropathy, namely, diabetic kidney disease and associated end stage renal disease has become a major global public health issue. Results of observational studies indicate that most diabetic kidney disease progresses over decades; however, certain diabetes patients display a rapid decline in renal function, which may lead to renal failure within months. Although the definition of rapid renal function decline remained speculative, in general,it is defined by the decrease of estimated glomerular filtration rate(e GFR) in absolute rate of loss or percent change. Based on the Kidney Disease: Improving Global Outcomes 2012 clinical practice guidelines, a rapid decline in renal function is defined as a sustained declinein e GFR of > 5 m L/min per 1.73 m2 per year. It has been reported that potential factors contributing to a rapid decline in renal function include ethnic/genetic and demographic causes, smoking habits, increased glycated hemoglobin levels, obesity, albuminuria, anemia, low serum magnesium levels, high serum phosphate levels, vitamin D deficiency, elevated systolic blood pressure, pulse pressure, brachial-ankle pulse wave velocity values, retinopathy, and cardiac autonomic neuropathy. This article reviews current literatures in this area and provides insight on the early detection of diabetic subjects who are at risk of a rapid decline in renal function in order to develop a more aggressive approach to renal and cardiovascular protection.Yi-Jing Sheen Wayne HH Sheu 2014World Journal of Diabetes2014,5,6:5
11Calcitriol analog ZK191784 ameliorates acute and chronic dextran sodium sulfate-induced colitis by modulation of intestinal dendritic cell numbers and phenotype显示文摘AIM: To investigate the effects of ZK1916784, a low calcemic analog of calcitriol on intestinal inflammation. METHODS: Acute and chronic colitis was induced by dextran sodium sulfate (DSS) according to standard procedures. Mice were treated intraperitoneally with ZK1916784 or placebo and colonic inflammation was evaluated. Cytokine production by mesenterial lymph node (MLN) cells was measured by ELISA. Immunohistochemistry was performed to detect intestinal dendritic cells (DCs) within the colonic tissue, and the effect of the calcitriol analog on DCs was investigated. RESULTS: Treatment with ZK191784 resulted in significant amelioration of disease with a reduced histological score in acute and chronic intestinal inflammation. In animals with acute DSS colitis, down- regulation of colonic inflammation was associated with a dramatic reduction in the secretion of the proinflammatory cytokine interferon (IFN)-γ and a significant increase in intereleukin (IL)-10 by MLN cells. Similarly, in chronic colitis, IL-10 expression in colonic tissue increased 1.4-fold when mice were treated with ZK191784, whereas expression of the Th1-specific transcription factor T-beta decreased by 81.6%. Lower numbers of infiltrating activated CD11c+ DCs were found in the colon in ZK191784-treated mice with acute DSScolitis, and secretion of proinflammatory cytokines by primary mucosal DCs was inhibited in the presence of the calcitriol analog. CONCLUSION: The calcitriol analog ZK191784 demonstrated significant anti-inflammatory properties in experimental colitis that were at least partially mediated by the immunosuppressive effects of the derivate on mucosal DCs.Ulrike G Strauch Florian Obermeier Nicole Grunwald Nadja Dunger Heiko C Rath Jürgen Schlmerich A Steinmeyer U Zügel HH Herfarth 2007World Journal of Gastroenterology2007,13,48:4

162型糖尿病患者及其一级亲属和非糖尿病者骨骼肌的胰岛素信号传导显示文摘2型糖尿病与骨骼肌和其他组织的葡萄糖利用能力下降有关。胰岛素抵抗可能与遗传因素和糖尿病本身的代谢异常如高血糖或非脂化脂肪酸(NEFA)升高有关。遗传因素和继发的胰岛素抵抗代谢异常可能是由于调节葡萄糖代谢的胰岛素受体和受体后信号传导的改变引起。胰岛素与其受体结合后,受体自身磷酸化,受体激酶活化,一些细胞间的底物磷酸化,其中在骨骼肌细胞中胰岛素受体底物-1(IRS-1)最重要。酪氨酸磷酸化的IRS与脂肪激酶磷脂酚肌醇3’(PI3’)Meyer MM Levin K Grimmsmann T Beck-Nielsen H Klein HH Diabetologia 叶华 2003中国糖尿病杂志2003,11,2:3

20Rb-Sr isotope dating of silicalite from the Dajiangping massive sulfide ore deposit,Guangdong Province显示文摘THE Dajiangping pyrite ore deposit located in the Yunfu County of Guangdong Province is asuper-large pyrite ore deposit.
