Crit Care:N-乙酰半胱氨酸和抗坏血酸能减少重症监护病人造影剂肾病吗?

由此可见,静脉注射N-乙酰半胱氨酸和抗坏血酸不能减少进行造影剂增强CT扫描的重症患者造影剂肾病发生,尽管治疗患者的8-异前列烷水平显着降低。

近日,危重病医学领域权威杂志Critical Care上发表了一篇研究文章,在这项研究中,研究人员旨在评估N-乙酰半胱氨酸和抗坏血酸是否可以减少危重病人造影剂肾病的发生率。  


这是一项在希腊拉里萨大学附属医院重症监护室进行的单中心,双组,前瞻性,随机开放对照试验。这些肾功能稳定且因诊断需要进行了非紧急造影剂曾强CT扫描的患者被纳入研究。治疗组患者(NacA,n=60)分别在造影剂输注前2小时,输注后10小时和18小时静脉注射了溶于100 ml生理盐水的N-乙酰半胱氨酸(1200mg)和抗坏血酸(2g),而对照组患者(CG,n=64)仅注射了生理盐水。所有患者接受额外的水化治疗。造影剂诱导的肾病被定义为相对于血清肌酸酐的基线值增加了25%。  

NacA和CG组造影剂肾病的比例分别为18.33%和15.6%(P=0.81)。NacA和CG组进行造影剂增强CT扫描后血清胱抑素-C(mg / L)从基础开始的变化百分比中位数分别为37.23%(28.53)和93.20%(46.90)(P=0.03)。相比于CG组,NacA组在注射放射性造影剂后2小时(P=0.012)和24小时(P=0.006)血清8-异前列烷水平显著低于CG。多变量分析显示造影剂肾病与较高的血清尿素/肌酐比值(比值比为1.02,95%可信区间为1.00-1.05)和肾毒性药物的使用(比值比为0.24,95%可信区间为0.06-0.94)独立相关。  

由此可见,静脉注射N-乙酰半胱氨酸和抗坏血酸不能减少进行造影剂增强CT扫描的重症患者造影剂肾病发生,尽管治疗患者的8-异前列烷水平显着降低。

N-乙酰基半胱氨酸,碳酸氢钠,他汀类药物,和抗坏血酸已被研究用于减少造影剂肾病(CIN)。该研究的目的是评估接受造影的成年人中减少CIN干预措施的效果比较。研究人员在2015年6月检索了MEDLINE,EMBASE,Cochrane图书馆,ClinicalTrials.gov,和Scopus数据库。研究的风险偏差和整体证据的综合实力(SOE)被进行了评估。研究人员选择了N-乙酰半胱氨酸,碳酸氢钠,

Oncotarget:维生素D缺乏通过激发肝细胞中的氧化应激引起胰岛素抵抗

胰岛素抵抗是指各种原因使胰岛素促进葡萄糖摄取和利用的效率下降,机体代偿性的分泌过多胰岛素产生高胰岛素血症,以维持血糖的稳定。胰岛素抵抗易导致代谢综合征和2型糖尿病。研究表明,维生素D缺乏可导致胰岛素抵抗。维生素D3是维生素D在人体内主要的活性形式,1α-羟化酶是激活维生素D3合成的关键酶。发表于Oncotarget的一篇文章中,研究人员发现,维生素D缺乏诱导的胰岛素抵抗与肝细胞氧化应激有关。

Circulation:N-乙酰半胱氨酸对动脉血栓的有效溶栓作用!

动脉血栓形成期间的血小板交联涉及了血管性血友病因子(VWF)多聚体。因此,VWF的蛋白水解似乎有望分解富含血小板的血栓并恢复急性血栓障碍,如缺血性中风、急性冠状动脉综合征或急性肢体缺血的血管通畅。 N-乙酰半胱氨酸(NAC,临床批准的粘液溶解药物)可以减少大聚合蛋白中的链内二硫键。近期,一项发表在杂志Circulation上的研究检测了NAC能否在闭塞性血栓内切断VWF多聚体,从而导致其
