为研究磁浮车辆悬浮控制器的状态观测器参数对悬浮稳定性的影响,解决磁浮车辆悬浮不稳的问题,建立单电磁铁与柔性轨道梁的耦合模型。通过对悬浮系统传递函数的研究,得到速度激励信号频率与悬浮系统对轨道梁的功率输出的关系曲线,并得到状态观测器参数对系统性能的影响规律。由此得出结论,通过绘制"悬浮系统对轨道梁的振动能量输出功率"与"轨道梁主频率"间的关系曲线,即可得到不考虑轨道梁阻尼时,悬浮系统可适应轨道的临界参数。

为了揭示失血和LPS刺激后中华绒螯蟹血细胞的生成及成熟过程,利用流式细胞技术将中华绒螯蟹造血组织细胞和血细胞按大小进行分类,利用EdU标记检测失血刺激后中华绒螯蟹造血组织细胞的增殖情况,分析失血和LPS刺激后中华绒螯蟹不同类型血细胞比例的变化.结果显示:中华绒螯蟹造血组织细胞分布于106~384μm^(2)之间,而血细胞分布在119~434μm^(2)之间,其中,透明细胞和小颗粒细胞主要分布在200~300μm^(2)之间,中颗粒和大颗粒细胞主要分布在300~400μm^(2)之间,随着血细胞颗粒性的增加,细胞逐渐增大.在失血刺激6、12和24 h时,中华绒螯蟹造血组织细胞增殖加速,说明失血刺激可以促进造血组织细胞增殖以加速新血细胞的生成.失血刺激2 h后透明细胞比例显著降低,至12 h时,各类细胞基本恢复至正常水平.LPS刺激1、3、6和9 h后,透明细胞比例呈现先降低后升高再降低的变化,而小、中和大颗粒细胞比例变化与透明细胞比例变化趋势相反,LPS刺激24 h和48 h后,透明细胞比例显著升高,大颗粒细胞比例显著降低.由此可知,失血和LPS刺激引起了中华绒螯蟹机体不同细胞的免疫反应,可能通过不同方式影响血细胞的生成、分化和成熟.

一部中国园林史由无数座名园个案连缀而成,宛如珍珠串起的项链,寄畅园是项链上一颗别致的明珠,因其精彩纷呈的历史,独到精湛的艺术,为人所津津乐道。寄畅园的传奇色彩首先来自其悠久的历史。这座园林1527年由秦金建造,此后迭经秦瀚、秦梁、秦燿、秦埈、秦伯钦、秦德藻、秦松龄、秦道然诸人之手,始终由秦氏保有,因称“秦园”。寄畅园背后的秦氏家族,历史还要更为久远,秦氏始祖是北宋文学家秦观,距今已近1 000年。寄畅园所在的惠山山顶有一座秦观墓,背靠三茅峰,前对太湖,气象开阔,不仅在文字图画上,更在真景实物上,将这个绵延千年的传奇家族展示在世人面前。

目的:观察慢性应激(CS)对阿尔茨海默病(AD)样学习记忆损伤模型大鼠海马齿状回(DG)的促肾上腺皮质激素释放因子(CRF)及其1型受体(CRFR1)的影响,并探讨CRFR1在CS引起的AD样模型大鼠空间学习和记忆能力改变中的作用。方法:雄性Wistar大鼠随机分为对照(CON)组、AD模型(AD)组和AD给予CS(AD+CS)组,每组7只。用侧脑室单次注射链脲佐菌素联合长期腹腔注射D-半乳糖(每天1次,共6周)的方法制备AD样学习记忆损伤模型大鼠;AD+CS组大鼠在D-半乳糖注射的后4周,每天随机给予一种应激原刺激。Morris水迷宫评估大鼠的空间学习和记忆能力;免疫组织化学染色观察海马Aβ_(1-42)的表达;ELISA检测DG区CRF的水平;Western blot法观察DG区CRFR1表达。之后,AD大鼠DG区注射CRFR1阻断剂R121919,观察其对CS条件下的AD样模型大鼠空间学习和记忆能力的影响。结果:与CON组比较,AD样模型大鼠的空间学习和记忆能力显著下降,且海马区Aβ_(1-42)沉积增多;而给予CS可缓解AD样模型大鼠的空间学习记忆障碍,减少海马Aβ_(1-42)沉积。与CON组比较,AD组大鼠DG区CRF水平和CRFR1表达均显著降低(P<0.05),而AD+CS大鼠DG区的CRF水平和CRFR1表达均显著高于AD组(P<0.05)。大鼠DG区微量注射R121919显著损伤CS条件下AD大鼠的空间学习和记忆能力(P<0.05)。结论:CS增加AD样模型大鼠DG区CRF水平,后者通过激活CRFR1减轻AD样模型大鼠的空间学习和记忆功能损伤。
