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内侧固定平台单髁置换术后的冠状面下肢力线是翻修的影响因素显示文摘膝关节单髁置换术(unicompartmental knee arthroplasty,UKA)后患者冠状面的下肢力线被认为是影响手术长期疗效的一个重要因素,但关于最佳的UKA术后下肢力线还没有形成明确共识。一些研究主张术后下肢力线应保持在中立位,而另一些研究认为即使术后下肢力线存在10°的内翻也可获得良好的临床效果。Sean E Slaven John P Cody Robert A Sershon Henry Ho Robert H Hopper Jr Kevin B Fricka 李亚坤(整理) 张民(整理) 2020实用骨科杂志2020,26,12:15
3No difference in mortality among ALPPS,two-staged hepatectomy,and portal vein embolization/ligation:A systematic review by updated traditional and network meta-analyses显示文摘Background:There is an ongoing debate on the feasibility,safety,and oncological efficacy of the associating liver partition and portal vein ligation for staged hepatectomy(ALPPS)technique.The aim of this study was to compare ALPPS,two-staged hepatectomy(TSH),and portal vein embolization(PVE)/ligation(PVL)using updated traditional meta-analysis and network meta-analysis(NMA).Data sources:Electronic databases were used in a systematic literature search.Updated traditional metaanalysis and NMA were performed and compared.Mortality and major morbidity were selected as primary outcomes.Results:Nineteen studies including 1200 patients were selected from the pool of 436 studies.Of these patients,315(31%)and 702(69%)underwent ALPPS and portal vein occlusion(PVO),respectively.Ninetyday mortality based on updated traditional meta-analysis,subgroup analysis of the randomized controlled trials(RCTs),and both Bayesian and frequentist NMA did not demonstrate significant differences between the ALPPS cohort and the PVE,PVL,and TSH cohorts.Moreover,analysis of RCTs did not demonstrate significant differences of major morbidity between the ALPPS and PVO cohorts.The ALPPS cohort demonstrated significantly more favorable outcomes in hypertrophy parameters,time to operation,definitive hepatectomy,and R0 margins rates compared with the PVO cohort.In contrast,1-year disease-free survival was significantly higher in the PVO cohort compared to the ALPPS cohort.Conclusions:This study is the first to use updated traditional meta-analysis and both Bayesian and frequentist NMA and demonstrated no significant differences in 90-day mortality between the ALPPS and other hepatic hypertrophy approaches.Furthermore,two high quality RCTs including 147 patients demonstrated no significant differences in major morbidity between the ALPPS and PVO cohorts.Paschalis Gavriilidis Robert P Sutcliffe Keith J Roberts Madhava Pai Duncan Spalding Nagy Habib Long R Jiao Mikael H Sodergren 2020Hepatobiliary & Pancreatic Diseases International2020,19,5:6
4Fluid balance concepts in medicine:Principles and practice显示文摘The regulation of body fluid balance is a key concern in health and disease and comprises three concepts. The first concept pertains to the relationship between total body water(TBW) and total effective solute and is expressed in terms of the tonicity of the body fluids. Disturbances in tonicity are the main factor responsible for changes in cell volume, which can critically affect brain cell function and survival. Solutes distributed almost exclusively in the extracellular compartment(mainly sodium salts) and in the intracellular compartment(mainly potassium salts) contribute to tonicity, while solutes distributed in TBW have no effect on tonicity. The second body fluid balance concept relates to the regulation and measurement of abnormalities of sodium salt balance and extracellular volume. Estimation of extracellular volume is more complex and error prone than measurement of TBW. A key function of extracellular volume, which is defined as the effective arterial blood volume(EABV), is to ensure adequate perfusion of cells and organs. Other factors, including cardiac output, total and regional capacity of both arteries and veins, Starling forces in the capillaries, and gravity also affect the EABV. Collectively, these factors interact closely with extracellular volume and some of them undergo substantial changes in certain acute and chronic severe illnesses. Their changes result not only in extracellular volume expansion, but in the need for a larger extracellular volume compared with that of healthy individuals. Assessing extracellular volume in severe illness is challenging because the estimates of this volume by commonly used methods are prone to large errors in many illnesses. In addition, the optimal extracellular volume may vary from illness to illness, is only partially based on volume measurements by traditional methods, and has not been determined for each illness. Further research is needed to determine optimal extracellular volume levels in several illnesses. For these reasons, extracellular volume in severe illness merits a separate third concept of body fluid balance.Maria-Eleni Roumelioti Robert H Glew Zeid J Khitan Helbert Rondon-Berrios Christos P Argyropoulos Deepak Malhotra Dominic S Raj Emmanuel I Agaba Mark Rohrscheib Glen H Murata Joseph I Shapiro Antonios H Tzamaloukas 2018World Journal of Nephrology2018,7,1:3
5Evaluation of a locked nucleic acid form of antisense oligo targeting HIF-1α in advanced hepatocellular carcinoma显示文摘BACKGROUND Hypoxia-inducible factor 1α(HIF-1α) is a gene that regulates tumor survival,neovascularization and invasion. Overexpression of HIF-1α correlates with poor prognosis in hepatocellular carcinoma(HCC). RO7070179 is a HIF-1α inhibitor that decreases HIF-1α mRNA and its downstream targets, it could be a potential treatment in HCC.AIM To evaluate safety and preliminary activity of RO7070179 in patients with previously treated HCC, with focus on a patient with prolonged response to RO7070179.METHODS In the preclinical study of RO7070179 in a HCC xenograft model, the mice wereseparated into 4 groups with each group received doses of 0, 3, 10 and 30 mg/kg for total 10 doses. HCC patients who failed at least one line of systemic treatment,received RO7070179 as a weekly infusion, each cycle is 6 wk. We evaluated the safety and HIF-1α mRNA levels of RO7070179.RESULTS Preclinical evaluation of RO7070179 in orthotopic HCC xenograft model showed no significant differences in HCC tumor weight between the 3 and 10 mg/kg groups. However, dose of 10 mg/kg of RO7070179, has shown 76% reduction of the amount of HIF-1α mRNA in HCC tissue. In the phase 1 b study of RO7070179 in previously treated HCC patients, 8 out of 9 were evaluable: 1 achieved PR and1 SD. The patient with PR responded after 2 cycles treatments, which has been maintained for 12 cycles. This patient also showed reduction in perfusion of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI) after 1 cycle of treatment. After 1 cycle of treatment, both patients with PR and SD showed decrease in HIF-1α mRNA at the root of biopsies(each biopsy was divided into 2 specimens, the tip and the root).CONCLUSION RO7070179 can reduce HIF-1α mRNA level in HCC patients with SD or PR. It is well tolerated at 10 mg/kg, with transaminitis as the dose of increased toxicity.This study indicates that RO7070179 might benefit HCC patients, and an early signal for clinical benefit can potentially be predicted through changes in either m RNA level or DCE-MRI within 1 cycle of therapy.Jennifer Wu Merly Contratto Krishna P Shanbhogue Gulam A Manji Bert H O'Neil Anne Noonan Robert Tudor Ray Lee 2019World Journal of Clinical Oncology2019,10,3:2

8Axial strain enhances osteotomy repair with a concomitant increase in connexin43 expression显示文摘The mechanical environment is known to influence fracture healing. We speculated that connexin43(Cx43) gap junctions, which impact skeletal homeostasis, fracture healing and the osteogenic response to mechanical load,may play a role in mediating the response of the healing bone to mechanical strain. Here, we used an established rat fracture model, which uses a 2 mm osteotomy gap stabilized by an external fixator, to examine the impact of various cyclical axial loading protocols(2%, 10%, and 30% strain) on osteotomy healing. We examined the presence of Cx43 in the osteotomy-healing environment and assessed how mechanical strain modulates Cx43 expression patterns in the callus. We demonstrated that increased cyclical axial strain results in increased radiographic and histologic bone formation. In addition, we show by immunohistochemistry that Cx43 is abundantly expressed in the healing callus, with the expression most robust in samples exposed to increased cyclical axial strain. These data are consistent with the concept that an increase in Cx43 expression by mechanical load may be part of the mechanisms by which mechanical forces enhances fracture healing.Rishi R Gupta Hyunchul Kim Yu-Kwan Chan Carla Hebert Leah Gitajn David J Yoo Robert V O’Toole Adam H Hsieh Joseph P Stains 2015Bone Research2015,3,2:2
