Time-selected nursing based on the midnight-noon ebb-flow theory to accelerate postoperative recovery in patients undergoing laparoscopic surgery (子午流注择时护理加速腹腔镜患者术后康复的研究进展)

open access: yes中西医结合护理
Laparoscopic surgery, despites its advantage of minimal invasive surgery, still presents challenges in enhanced recovery after surgery (ERAS) protocols, including postoperative ileus, pain-related stress, and circadian rhythm disturbances.

oleoylethanolamide improves spatial cognitive deficits through enhancing hippocampal neurogenesis after cerebral ischemia [PDF]

open access: yes, 2015
我们先前的研究表明油酰乙醇胺(OEA)对急性脑缺血损伤具有神经保护作用。本研究的目的是探讨OEA对脑缺血引起的空间认知障碍,海马长时程增强作用(LTP)的抑制作用和海马神经发生的影响。结果表明:OEA30mg/kg显著改善大鼠脑缺血后空间认知功能障碍,促进海马长时程增强。另外,我们证实OEA通过促进海马神经发生改善脑缺血后的认知障碍。进一步的研究表明,OEA明显增加海马组织脑源性神经营养因子(BDNF)和过氧化物酶体增殖活化受体(PPARα)的表达 ...

左卡尼汀对老年冠心病患者心率变异性的影响

open access: yesZhongguo shiyan zhenduanxue, 2015
心率变异性(heart20rate20variability,HRV)是指逐次心跳周期的差异,即正常窦性心动周期围绕其均值波动的现象,是用于评价自主神经系统兴奋性的一种非侵入性指标[1,2]。在正常生理情况下,心血管系统的功能受到植物神经系统调控,使窦房结按照一定的节律发放冲动,实现心率的昼夜变化,交感神经使心率快速化,而副交感神经使心率慢速化[3 ...

Research on The Long-distance Trafficking of FT mRNA Through The Endoplasmic Reticulum System in Arabidopsis [PDF]

open access: yes, 2011
拟南芥开花调控分为四条途径:光周期途径、春化途径、赤霉素途径和自主途径,其中FLOWERLOCUST(FT)是光周期途径中重要的调控基因,也是四条开花调控途径关键的整合因子,其表达产物具有长距离运输的功能。实验室已有研究证明FT蛋白和FTmRNA共同参与了长距离运输,本研究主要针对FT蛋白与FTmRNA的转运模式展开研究,得到了以下结果:(1)通过将FT蛋白与不同定位信号肽的融合将FT蛋白分别定位到内质网、线粒体和叶绿体中,发现内质网中的FT蛋白参与协同FTmRNA的长距离运输。(2 ...

异氟醚麻醉对大鼠海马乙酰胆碱昼夜节律变化的影响

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2008
【目的】本实验旨在探讨异氟醚麻醉对大鼠海马乙酰胆碱(ACh)昼夜节律变化的影响,并比较在暗期及明期麻醉对该节律变化的影响。【方法】 采用活体微透析技术,每20min从大鼠海马处连续收集透析液3d,并自动注射到高效液相色谱仪中以测定ACh浓度。大鼠共分3组(每组6只):对照组;明期给药组(从11:00至15:00h予1.4%异氟醚麻醉);暗期给药组(从23:00至03:00h予1.4%异氟醚)。所有大鼠放置于明暗周期下喂养(明期07:00-19:00h)。【结果】对照组海马ACh呈明显的昼夜节律变化 ...

The Regulation of LEAFY Expression by Flowering _Time Genes in Arabidopsis [PDF]

open access: yes, 2009
LEAFY(LFY)基因是拟南芥营养生长向生殖生长转变过程中的一个重要因子,对于成花诱导的启动是必需的,与FLOWERLOCUST(FT)、FLOWERINGLOCUSD(FD)、SUPPRESSOROFOVEREXPRESSIONOFCONSTANS1(SOC1)基因一起被认为是四条开花促进途径的整合因子,在整个成花调控网络中处于关键位点,但是具体的调控机理目前尚不完全清楚,本研究主要针对FT、FD、SOC1与LFY之间的调控机理进行研究。通过将35S::LFY植株杂交到ft10、fd3、soc1-2、
