2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

4Gastroesophageal reflux: the features in elderlypatients显示文摘AIM To compare the features ofgastroesophageal reflux disease between elderlyand younger patients.METHODS Twenty-four hour pH-monitoring andendoscopy were P6rformed for the 66 elderlypatients with typical gastroesophageaI refluxsymptoms, and the results were compared with112 symptomatic younger patients.RESULTS The results of 24-h pH-monitoringand endoscopy showed that the elderly patientshad pathological reflux and reflux esophagitismore frequently than the younger patients.P6rcentage time with pH< 4 in elderly patientswith reflux esophagitis was 32.5% in 24 hours,as compared with 12.9% in the younger patientswith reflux esophagitis (P < 0 .05 ). The elderlypatients with reflux esophagitis have longerP6riOds of acid reflux in both upright and Supinepositions than the younger patients. Endoscopyshowed that 20 .8% of elderIy patients had grade Ⅲ / Ⅳ esophagitis, whereas only 3.4% ofyounger patients had grade Ⅲ/ Ⅳ esophagitis(P < 0.002 ). Percentages of grades Ⅰ /Ⅱesophagitis in the two groups were 12.5% and26. 5%, respectiveIy (P< 0. 002 ).CONCLUSION Elderly patients, as comparedwith younger patients, have more severegastroesophageal reflux and esophageal lesions.The incompetence of lower esophageal sphincter and the presence of hiataI hernia may beimportant factors leading to the difference in incidence and severity of reflux esophagitisbetween elderly and younger patients.Huang X Zhu HM Deng CZ Porro GB Sangaletti O Pace F 1999World Journal of Gastroenterology1999,5,5:12

6Fecal markers of inflammation used as surrogate markers for treatment outcome in relapsing inflammatory bowel disease显示文摘AIM: To evaluate fecal calprotectin (FC) as a surrogate marker of treatment outcome of relapse of inflammatory bowel disease (IBD) and, to compare FC with fecal myeloperoxidase (MPO) and fecal eosinophil protein X (EPX). METHODS: Thirty eight patients with IBD, comprising of 27 with ulcerative colitis (UC) and 11 with Crohn’s disease (CD) were investigated before treatment (inclusion), and after 4 and 8 wk of treatment. Treatment outcomes were evaluated by clinical features of disease activity and endoscopy in UC patients, and disease activity in CD patients. In addition, fecal samples were analyzed for FC by enzyme-linked immunosorbent assay (ELISA), and for MPO and EPX with radioimmunoassay (RIA). RESULTS: At inclusion 37 of 38 (97%) patients had elevated FC levels (> 94.7 μg/g). At the end of the study, 31 of 38 (82%) patients fulfilled predefined criteria of a complete response [UC 21/27 (78%); CD 10/11 (91%)]. Overall, a normalised FC level at the end of the study predicted a complete response in 100% patients, whereas elevated FC level predicted incomplete response in 30%. Normalised MPO or EPX levels predicted a complete response in 100% and90% of the patients, respectively. However, elevated MPO or EPX levels predicted incomplete response in 23% and 22%, respectively. CONCLUSION: A normalised FC level has the potential to be used as a surrogate marker for successful treatment outcome in IBD patients. However, patients with persistent elevation of FC levels need further evaluation. FC and MPO provide superior discrimination than EPX in IBD treatment outcome.Michael Wagner Christer GB Peterson Peter Ridefelt Per Sangfelt Marie Carlson 2008World Journal of Gastroenterology2008,14,36:9

10Anti-arthritis activity of roots of Hemidesmus indicus R.Br.(Anantmul)in rats显示文摘Objective:To investigate the protective effects of hydroalcoholic and its fractions from roots of Hemidesmus indicus on arthritis in in vitro models of rodents.Methods:Preliminary phytochemical analysis and thin-layer chromoatography were performed to analyze constituents of hydroalcoholic extract and its three fraction namely ethyl acetate fraction,chloroform fraction and residual fraction of mot of Hemidesmus indicus.Arthritis rats models were established by Complete Freund’s Adjuvant.The parameters including paw edema,body weight,arthritic index,erythrocyte sedimentation rate,serum rheumatoid factor,serum C-reactive protein,serum nitrite level,and histopathology of synovial joints were observed.Methotrexate was taken as positive control.Results:Rats treated with hydroalcoholic extract(450 mg/kg,p.o.),ethyl acetate (75 mg/kg,p.o.),chloroform(60 mg/kg,p.o) and residual fractions(270 mg/kg,p.o.),showed significant decrease in physical and biochemical parameters compared with arthritic model rats. Hydroalcoholic extract and its ethyl acetate fraction of Hemidesmus indicus showed significantly higher anti-arthritic activity than chloroform and residual fraction.Histopathological analysis demonstrated that both of hydroalcoholic extract and its ethyl acetate fraction had comparable anti-arthritic activity with methotrexates.Conclusions:The present study suggests that Hemidesmus indicus has protective activity against arthritis and the activity might be attributed to presence of terpenoid in hydroalcoholic extract,as well as in ethyl acetate fraction.Alka Mehta Neeraj K Sethiya Chetan Mehta GB Shah 2012Asian Pacific Journal of Tropical Medicine2012,5,2:4

12Twenty-five years of research on the effects of exercise training in breast cancer survivors:A systematic review of the literature显示文摘AIM:To investigate the role of exercise training the past 25 years on major physiological-psychological outcomes studied thus far in this patient population.METHODS:Pub Med, Medline Plus, the Cochrane Library, Web of Science, SportD iscus, Embase, Scorpus, and Google Scholar were searched from September to November 2013 to identify exercise training studies that used objective measurements of fitness and/or patient reported outcomes assessed pre and post-exercise training with statistical analyses performed in at least one of the following outcome measurements:Cardiorespiratory function, body composition, muscular strength, fatigue, depression, and overall quality of life. Five reviewers independently identified the studies that met the criteria for the review and discrepancies were resolved by consensus among all authors.RESULTS:Fifty-one studies were included in this review with 5 from the period between 1989-1999, 11 from 2000-2006, and 35 from 2007-2013. The evolution of study designs changed from aerobic only exercise training interventions(1989-1999), to a combination of aerobic and resistance training(2000-2006), to studies including an arm of resistance training or examining the effects of resistance training as the main mode of exercise(2007-2013). Overall, the benefits of exercise showed improvements in cardiorespiratory function, body composition, strength, and patient reported outcomes including fatigue, depression, and quality of life.CONCLUSION:Exercise training appears to be safe for most breast cancer patients and improvements in physiological, psychological, and functional parameters can be attained with regular participation in moderate intensity exercise.Claudio L Battaglini Robert C Mills Brett L Phillips Jordan T Lee Christina E Story Marcelo GB Nascimento Anthony Carl Hackney 2014World Journal of Clinical Oncology2014,5,2:3
