| 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 | Autoimmune gastritis:Pathologist's viewpoint显示文摘Western countries are seeing a constant decline in the incidence of Helicobacter pylori-associated gastritis, coupled with a rising epidemiological and clinical impact of autoimmune gastritis. This latter gastropathy is due to autoimmune aggression targeting parietal cells through a complex interaction of auto-antibodies against the parietal cell proton pump and intrinsic factor, and sensitized T cells. Given the specific target of this aggression, autoimmune gastritis is typically restricted to the gastric corpus-fundus mucosa. In advanced cases, the oxyntic epithelia are replaced by atrophic(and metaplastic) mucosa, creating the phenotypic background in which both gastric neuroendocrine tumors and(intestinal-type) adenocarcinomas may develop. Despite improvements in our understanding of the phenotypic changes or cascades occurring in this autoimmune setting, no reliable biomarkers are available for identifying patients at higher risk of developing a gastric neoplasm. The standardization of autoimmune gastritis histology reports and classifications in diagnostic practice is a prerequisite for implementing definitive secondary prevention strategies based on multidisciplinary diagnostic approaches integratingendoscopy, serology, histology and molecular profiling. | Irene Coati Matteo Fassan Fabio Farinati David Y Graham Robert M Genta Massimo Rugge | 2015 | World Journal of Gastroenterology2015，21，42： | 8 |
| 3 | Altered vasoactive intestinal peptides expression in irritable bowel syndrome patients and rats with trinitrobenzene sulfonic acid-induced colitis显示文摘AIM: To investigate the vasoactive intestinal peptides(VIP) expression in irritable bowel syndrome(IBS) and trinitrobenzene sulfonic acid(TNBS) induced colitis.METHODS: The VIP gene expression and protein plasma levels were measured in adult participants(45.8% male) who met Rome Ⅲ criteria for IBS for longer than 6 mo and in a rat model of colitis as induced by TNBS.Plasma and colons were collected from naive and inflamed rats.Markers assessing inflammation(i.e.,weight changes and myeloperoxidase levels) were assessed on days 2,7,14 and 28 and compared to controls.Visceral hypersensitivity of the rats was assessed with colo-rectal distension and mechanical threshold testing on hind paws.IBS patients(n = 12) were age,gender,race,and BMI-matched with healthy controls(n = 12).Peripheral whole blood and plasma from fasting participants was collected and VIP plasma levels were assayed using a VIP peptide-enzyme immunoassay.Human gene expression of VIP was analyzed using a custom PCR array.RESULTS: TNBS induced colitis in the rats was confirmed with weight loss(13.7 ± 3.2 g) and increased myeloperoxidase activity.Visceral hypersensitivity tocolo-rectal distension was increased in TNBS treated rats up to 21 d and resolved by day 28.Somatic hypersensitivity was also increased up to 14 d post TNBS induction of colitis.The expression of an inflammatory marker myeloperoxidase was significantly elevated in the intracellular granules of neutrophils in rat models following TNBS treatment compared to naive rats.This confirmed the induction of inflammation in rats following TNBS treatment.VIP plasma concentration was significantly increased in rats following TNBS treatment as compared to naive animals(P < 0.05).Likewise,the VIP gene expression from peripheral whole blood was significantly upregulated by 2.91-fold in IBS patients when compared to controls(P < 0.00001; 95%CI).VIP plasma protein was not significantly different when compared with controls(P = 0.193).CONCLUSION: Alterations in VIP expression may play a role in IBS.Therefore,a better understanding of the physiology of VIP could lead to new therapeutics. | Arseima Y Del Valle-Pinero LeeAnne B Sherwin Ethan M Anderson Robert M Caudle Wendy A Henderson | 2015 | World Journal of Gastroenterology2015，21，1： | 7 |
| 4 | Modified Cam-Clay model incorporating unified nonlinear strength criterion显示文摘A unified nonlinear strength criterion(i.e UNS criterion) is proposed,for the sake of versatility,to capture the complex strength behaviors of frictional materials in geotechnical field.It covers wide ranges on the meridian and octahedral planes to describe nonlinear strength behaviors of soils.The Modified Cam-Clay model,incorporating the unified nonlinear strength criterion,is employed as an example to derive working mathematical equations and to illustrate yielding surfaces in three-dimensional stress space for improving the model's predictive capability.The unified nonlinear strength criterion,demonstrated here,is capable of capturing the experimental results of different types of soils on the meridian and octahedral planes.In addition,the revised model,based on this unified nonlinear strength criterion,though very simple,is versatile to predict the true triaxial test results from literature when considering the influences of the intermediate principal stress on strength and deformation under complex stress conditions. | XIAO Yang LIU HanLong LIANG Robert Y | 2011 | Science China(Technological Sciences)2011，54，4： | 6 |

| 8 | Inhibition of hepatitis C virus replication by single-stranded RNA structural mimics显示文摘AIM: To examine the effect of hepatitis C virus (HCV) structural mimics of regulatory regions of the genome on HCV replication.METHODS: HCV RNA structural mimics were constructed and tested in a HCV genotype 1b aBB7 replicon,and a Japanese fulminant hepatitis-1 (JFH-1) HCV genotype 2a infection model.All sequences were computer-predicted to adopt stem-loop structures identical to the corresponding elements in full-length viral RNA.Huh7.5 cells bearing the BB7 replicon or infected with JFH-1 virus were transfected with expression vectors generating HCV mimics and controls.Cellular HCV RNA and protein levels were quantified by real-time polymerase chain reaction and Western blotting,respectively.To evaluate possible antisense effects,complementary RNAs spanning a mimic were prepared.RESULTS: In the BB7 genotype 1b replicon system,mimics of the polymerase (NS-5B),X and BA regions inhibited replication by more than 90%,50%,and 60%,respectively.In the JFH-1 genotype 2 infection system,mimics that were only 74% and 46% identical in sequence relative to the corresponding region in JFH-1 inhibited HCV replication by 91.5% and 91.2%,respectively,as effectively as a mimic with complete identity to HCV genotype 2a.The inhibitory effects were confirmed by NS3 protein levels.Antisense RNA molecules spanning the 74% identical mimic had no significant effects.CONCLUSION: HCV RNA structural mimics can inhibit HCV RNA replication in replicon and infectious HCV systems and do so independent of close sequence identity with the target. | Robert Smolic Martina Smolic John H Andorfer Catherine H Wu Robert M Smith George Y Wu | 2010 | World Journal of Gastroenterology2010，16，17： | 2 |
