大鼠体外循环模型肺部炎症反应的研究

open access: yesZhongguo shiyan zhenduanxue, 2005
目的在体外循环(CBP)过程中产生的全身炎症反应与术后呼吸功能不全有关,本实验研究p38丝裂原激活蛋白激酶(p38MAPK)与体外循环中肺损伤的内在关系。方法复制大鼠体外循环模型,随机分为2组,实验组和对照组,每组9只。实验组体外循环30分钟后,开放肺动脉,接呼吸机,30分钟后取左肺肺组织;对照组只是行胸部正中切口,全身肝素化。检测大鼠肺组织p38MAPK活性,测定p38MAPK的表达。肺组织的炎症反应通过检测TNF-α、IL-1β和组织学改变来测定。肺水肿通过估计组织中水的百分比来测定 ...

The Dependence of Properties on Structural Features in Macro/Micro Levels for PBF‐LB Fabricated Porous NiTi Alloy

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Porous NiTi alloys are widely used in biomedical and engineering fields. Using the PBF‐LB technique, the TPMS and Voronoi porous parts with a porosity of ∼67% and a minimum feature size of 0.15 ± 0.02 mm were fabricated. Although the bulk sample fabricated with the same parameters is defect‐free, μ‐CT reconstruction on the porous sample ...

184例体外循环下心内直视术的护理配合

open access: yesHuli yanjiu, 2008
摘要: (免费在线浏览)体外循环是将回心的静脉血从上、下腔静脉或右心房引出体外,在人工心肺机进行氧合和排出二氧化碳后,再由血泵输回体内动脉的一种血液循环方法。体外循环下心内直视手术是治疗先天性心脏病、风湿性心脏病和冠心病的主要方法之一。体外循环下心内直视手术的特点是专业性强、手术步骤复杂、病人危险性大,因此护理人员手术前的准备和手术中与手术医生之间的配合对于手术成功起到至关重要的作用。本院在2007年1月―2007年12月对184例心脏病人施行了体外循环下心内直视手术,效果满意 ...

N,W‐Cooperative Modulation of Ni3S2 for Efficient Electrocatalytic Oxidation of 5‐Hydroxymethylfurfural to 2,5‐Furandicarboxylic Acid

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Ni3S2 has emerged as a promising catalyst for the electrochemical oxidation of biomass‐derived 5‐hydroxymethylfurfural (HMF) to 2,5‐furandicarboxylic acid (FDCA), driven by its distinctive physicochemical properties. However, its practical catalytic efficiency is severely hindered by abundant electrochemically inactive surface sites and poor ...
