9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
10高掺量粉煤灰高延性水泥基复合材料的制备和性能显示文摘高延性水泥基复合材料(high ductility cementitious composites,HDCC)是一种具有应变硬化、多缝开裂和高延性等特性的新型纤维增强水泥基复合材料,其材料设计必须取得基体韧度、界面黏结和纤维特性三者的最优组合,因此,HDCC的制备必须优选原材料和优化配合比,以取得最优的材料制备技术。从配合比设计入手,研究了粉煤灰含量、胶砂比等对HDCC力学性能的影响,优化了特定材料下的材料制备技术。结果表明:粉煤灰含量、胶砂比和养护条件对HDCC的拉伸性能均具有较大的影响。随着粉煤灰掺量的增大,砂含量的降低,拉伸应变增大。当砂含量较高时,基体开裂韧度较高,基体的极限拉伸应力下对应的极限拉伸应变较小,然而随着应力的下降,复合材料仍然能维持相当大的应变。庞超明 LEUNG C K Y 孙伟 2009硅酸盐学报2009,37,12:30

16体内腺相关病毒-常间回文重复序列丛集及其相关蛋白9介导的基因编辑可改善家族性高胆固醇血症的动脉粥样硬化显示文摘低密度脂蛋白受体(low-density lipoprotein receptor,Ldlr)基因突变是家族性高胆固醇血症的主要原因之一,可导致动脉粥样硬化,并具有很高的终生心血管病风险。常间回文重复序列丛集(clustered regularly interspaced short palindromic repeats,CRISPR)/CRISPR相关蛋白9(CRISPR-related protein 9,Cas9)系统是基因编辑纠正基因突变从而改善疾病的有效工具。该研究的目的是通过腺相关病毒(adeno-associated virus,AAV)携带的CRISPR/Cas9系统进行体内体细胞基因编辑,以确定其能否在小鼠模型中治疗由Ldlr突变体引起的家族性高胆固醇血症。刘青(译) 叶鹏(审校) Zhao H Li Y He L Pu W Yu W Li Y Wu YT Xu C Wei Y Ding Q Song BL Huang H Zhou B 2020中华高血压杂志2020,28,3:22

18Adenoid cystic carcinoma of breast: Recent advances显示文摘Adenoid cystic carcinoma(ACC) of the breast is a rare special subtype of breast cancer characterized by the presence of a dual cell population of luminal and basaloid cells arranged in specific growth patterns. Most breast cancers with triple-negative, basal-like breast features(i.e., tumors that are devoid of estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 expression, and express basal cell markers) are generally high-grade tumors with an aggressive clinical course. Conversely, while ACCs also display a triple-negative, basal-like phenotype, they are usually low-grade and exhibit an indolent clinical behavior. Many discoveries regarding the molecular and genetic features of the ACC, including a specific chromosomal translocation t(6;9) that results in a MYB-NFIB fusion gene, have been made in recent years. This comprehensive review provides our experience with ACC of the breast, as well as an overview of clinical, histopathological, and molecular genetic features.Kosuke Miyai Mary R Schwartz Mukul K Divatia Rose C Anton Yong Wook Park Alberto G Ayala Jae Y Ro 2014World Journal of Clinical Cases2014,2,12:16
19miR-182参与调节胶质母细胞瘤的凋亡、生长和分化(英文)显示文摘Glioblastoma multiforme(GBM)is a lethal,therapy-resistant brain cancer consisting of numerous tumor cell subpopulations,including stem-like glioma-initiating cells(GICs),which contribute to tumor recurrence following initial response to therapy.Here,we identified miR-182 as a regulator of apoptosis,growth,and differentiation programs whose expression level is correlated with GBM patient survival.Repression of Bcl2-like12(Bcl2L12),c-Met,and hypoxia-inducible factor 2α(HIF2A)is of central importance to miR-182 anti-tumor activity,as it results in enhanced therapy susceptibility,decreased GIC sphere size,expansion,and stemness in vitro.To evaluate the tumor-suppressive function of miR-182 in vivo,we synthesized miR-182-based spherical nucleic acids(182-SNAs);i.e.,gold nanoparticles covalently functionalized with mature miR-182 duplexes.Intravenously administered 182-SNAs penetrated the bloodbrain/blood-tumor barriers(BBB/BTB)in orthotopic GBM xenografts and selectively disseminated throughout extravascular glioma parenchyma,causing reduced tumor burden and increased animal survival.Our results indicate that harnessing the anti-tumor activities of miR-182 via safe and robust delivery of 182-SNAs represents a novel strategy for therapeutic intervention in GBM.Kouri FM Hurley LA Daniel WL Day ES Hua Y Hao L Peng CY Merkel TJ Queisser MA Ritner C Zhang H James CD Sznajder JI Chin L Giljohann DA Kessler JA Peter ME Mirkin CA Stegh AH 2015中华神经外科疾病研究杂志2015,14,2:14
