罗格列酮对压力超负荷大鼠血流动力学及心肌肥厚的影响 [PDF]
Zhongshan Daxue xuebao. Yixue kexue ban, 2006 【目的】探讨过氧化物酶体增殖物激活受体γ（PPAR-γ）配体罗格列酮对压力超负荷大鼠血流动力学及心肌肥厚的影响。【方法】30只SD大鼠随机分为假手术组（n=9）和压力超负荷模型组（n=21），应用腹主动脉缩窄的方法制作压力超负荷模型，将制作模型后24h仍存活的16只大鼠随机分为压力超负荷（PO）组（n=7）和罗格列酮（PO＋Ros）组（n=9）。罗格列酮组给予罗格列酮3mg／（kg·d）共8周。8周后测定血流动力学；称量心脏质量；放射免疫分析方法测量血浆肾素活性、血管紧张素Ⅱ和醛固酮。【结果 ...

罗格列酮对心肌梗死大鼠血流动力学及肾素-血管紧张素系统的影响 [PDF]
Zhongshan Daxue xuebao. Yixue kexue ban, 2004 【目的】探讨过氧化物酶体增殖物激活受体γ(PPARγ)激动药罗格列酮对心肌梗死大鼠血流动力学及肾素-血管紧张素系统的影响。【方法】45只SD大鼠随机分为假手术组(9只)和心肌梗死组(36只),将制作心肌梗死模型后24h仍存活的21只SD大鼠随机分为心肌梗死对照组(10只)和罗格列酮组(11只)。罗格列酮组术后24h开始给予罗格列酮3mg/(kg·d)共8周。8周后测定血流动力学,称量心脏、左室、右室、肺和肝质量,用放射免疫法测定血浆及心肌血管紧张素Ⅱ、醛固酮以及血浆肾素活性。【结果】与心肌梗死对照组相比,

Understanding Traditional Chinese Medicine to strengthen conservation outcomes
People and Nature, Volume 3, Issue 1, Page 115-128, February 2021., 2021 Abstract Numerous treatments in Traditional Chinese Medicine (TCM) involve the use of wildlife products, including some that utilize ingredients derived from endangered flora and fauna. Demand for such endangered wildlife products in TCM can threaten the survival of species and pose serious challenges for conservation.

血流动力学在脑血管病影像教学中的意义 Significance of Hemodynamics in Cerebrovascular Diseases Imaging Teaching
Zhongguo cuzhong zazhi, 2018 随着医学影像技术的快速发展，将流体力学与医学影像相结合使得血流动力学的可视化 变为现实。目前血流动力学在脑血管病中发挥重要作用，应用也越来越广泛，但是在脑血管病影像教 学中，对血管的评价多局限于结构学，而血流动力学能够让学生更直观地观察到不同部位不同疾病 的血流状态，便于理解与掌握，而且可以刷新传统医学课本对脑血管病的认识，有助于学生开展科 研工作。因此，血流动力学在脑血管病影像教学中具有重要意义。 Abstract: With the rapid development of ...
