| 1 | 限制热量摄入6个月对超重者寿命指标、代谢调节及氧化应激的影响——随机对照试验AuthorAffiliations:PenningtonBiomedicalResearchCenter.LouisianaStateUniversity.BatonRouge;andGarvan.InstituteforMedicalResearch.Dadinghurst,AustraIia(DrHeilbronn).显示文摘背景:长期限制热量摄入可延长啮齿类动物的寿命。但是,尚未有研究观测长期限制人体热量是否会影响其寿命及氧化应激指标,降低代谢率。
目的:在超重但不肥胖(体重指数为25—30)的人群中研究限制热量6个月伴/不伴运动对其产生的影响。
设计、地点及参试者:于2002年3月至2004年8月在位于路易斯安娜州首府巴顿鲁治的研究中心对48名不好动的健康人进行随机对照研究。
干预:参试者在6个月内随机分为4个组:对照组(饮食可维持体重);限制热量组(限制基线所需能量的25%);限制热量+运动组(限制12.5%的热量+运动增加12.5%的能耗);极低热量饮食组(每日摄入890keal,直至体重减少15%,随后采用维持体重的饮食)。
主要观测指标:机体组成;硫酸脱氢表雄酮(dehydroepiandrostemne sulfate,DHEAS)、葡萄糖及胰岛素水平;蛋白羰基化合物;DNA损伤;24小时能耗;核心体温。
结果:6个月时各组体重变化的均值(标准误)为:对照组-1.0%(1.1%);限制热量组-10.4%(0.9%);限制热量+运动组-10.0%(0.8%);极低热量饮食组-13.9%(0.7%)。6个月时,各干预组空腹血糖水平较基线明显降低(P均〈0.01),而DHEAS和葡萄糖水平没有改变。限制热量组及限制热量+运动组核心体温有所下降(P均〈0.05)。对机体组成进行校正后发现,对照组24小时静息能耗无变化,但限制热量组(-135kcal/d[42kcal/d])、限制热量+运动组(-117kcal/d[52kcal/d])和极低热量饮食组(-125kcal/d[35kcal/d])24小时静息能耗有所下降(P均〈0.008)。上述“代谢调节”(超出预计值的-6%)与对照组相比存在显著差异(P〈0.05)。6个月时,各组蛋白羰基化合物的浓度较基线时无变化,而各干预组DNA损伤有所减少(P〈0.005)。
结论:我们的研究结果显示,长期限制热量可降低人类寿命的2种指标(即空腹胰岛素水平和体温)。此外,我们的研究结果还支持下述理论,即限制热量能降低代谢率,且超过缩小代谢面积产生的相应效应。我们尚需开展远期研究来评价限制热量能否延缓人类衰老过程。 | Leonie K. Heibronn Lilian de Jonge Madlyn I. Frisard James P. DeLany D.

| 4 | Hepatocellular carcinoma after Iocoregional therapy:Magnetic resonance imaging findings in falsely negative exams显示文摘AIM:To elucidate causes for false negative magnetic resonance imaging(MRI)exams by identifying imaging characteristics that predict viable hepatocellular carcinoma(HCC)in lesions previously treated with locoregional therapy when obvious findings of recurrence are absent.METHODS:This retrospective institutional review board-approved and Health Insurance Portability and Accountability Act-compliant study included patients who underwent liver transplantation at our center between 1/1/2000 and 12/31/2012 after being treated for HCC with locoregional therapy.All selected patients had a contrast-enhanced MRI after locoregional therapy within 90 d of transplant that was prospectively interpreted as without evidence of residual or recurrenttumor.Retrospectively,2 radiologists,blinded to clinica and pathological data,independently reviewed the pre transplant MRIs for 7 imaging features.Liver explan histopathology provided the reference standard,with clinically significant tumor defined as viable tumor≥1.0cm in maximum dimension.Fisher’s exact test was firs performed to identify significant imaging features.RESULTS:Inclusion criteria selected for 42 patients with 65 treated lesions.Fourteen of 42 patients(33%and 16 of 65 treated lesions(25%)had clinically significant viable tumor on explant histology.None o the 7 imaging findings examined could reliably and reproducibly determine which treated lesion had viable tumor when the exam had been prospectively read as without evidence of viable HCC.CONCLUSION:After locoregional therapy some treated lesions that do not demonstrate any MRI evidence o HCC will contain viable tumor.As such even patients with a negative MRI following treatment should receive regular short-term imaging surveillance because some have occult viable tumor.The possibility of occult tumo should be a consideration when contemplating any action which might delay liver transplant. | David Becker-Weidman Jesse M Civan Sandeep P Deshmukh Christopher G Roth Steven K Herrine Laurence Parker Donald G Mitchell | 2016 | World Journal of Hepatology2016，8，16： | 2 |
