目的:研究5-HT3拮抗剂止吐药格拉司琼对大鼠体内洛铂(抗癌药物)药动学的影响. 方法:Wistar♂大鼠随机分为两组(n=10),洛铂给药剂量为10.64mg·kg-1.第1组只给洛铂,第2组给洛铂前30min给予格拉司琼0.4mg·kg-1,两组大鼠分别于给药前和给药后0,5,15,30,60,90,120,240,360,480min取血用于测定药代动力学. 结果:洛铂检测浓度的线性范围为0.5~80.0μg·mL-1(r=0.9999),方法回收率为96.62%~107.9%,日内、日间RSD均<9%.对照组和实验组洛铂的药动学参数分别为:AUC(0-∞):(42.32±13.38)、(43.83±9.20)mg·h·L-1,Cmax:(66.81±11.01)、(70.76±9.11)mg·L-1,t1/2z:(2.00±0.62)、(1.72±0.58)h.各项参数均无统计学意义(P>0.05). 结论:洛铂单独使用的药代动力学参数和与格拉司琼合用的药代动力学参数之间没有显著性差异.格拉司琼对洛铂的药动学没有影响.

目的:抑郁症的脑功能连接网络(functional connectivity,FC)异常是其潜在的疾病机制之一,既往多依据研究目标来预先设定感兴趣脑区,进而分析其脑功能连接网络.然而,目前对于抑郁症的全脑功能连接网络特性研究较少,对其与抑郁症核心临床特征(例如:"无助感")的相关机制知之甚少.本研究即探索了抑郁症核心临床特征的潜在全脑功能网络的机制.
目的:精神分裂症的早期识别问题亟待解决.前脉冲抑制(Prepulse Inhibition,PPI)缺陷及注意缺陷均是该病的内表型指标,可用于病因机制研究.然而,早期研究显示,PPI缺乏灵敏性及特异性,因此,优化PPI范式,提高其效应尺度成为PPI研究的关键.动物实验证实,正常小鼠可利用知觉空间线索提高PPI水平,而模型组则存在缺陷.所以,PPI知觉空间分离范式可作为潜在生物学指标展开研究.
目的:神经肽Y (NPY)基因定位于7号染色体,rs16147是NPY基因启动子区域的多态性位点.研究显示,rs16147多态性位点对NPY基因表达产生显著影响,A等位基因使得NPY表达增加.抑郁症患者外周或脑脊液NPY浓度较健康对照者减少.静脉注射NPY后,能缓解大鼠抑郁症行为.本研究旨在探讨氟西汀治疗抑郁症疗效与神经肽Y(NPY)基因多态性rs16147之间的关系.

目的:探讨临床药师参与药物治疗及开展药学监护的切入点.方法:针对一例行主动脉内球囊反搏术后合并多个并发症的患者,临床药师从药物的选择、药物剂量的调整,药物不良反应监测等多方面进行药学监护.结果:本次药学监护取得了明显成效.结论:主动脉内球囊反搏术后患者可作为临床药师的重点监护对象,临床药师参与该类患者的药物治疗很有意义.
