It is terribly wrong to make patients serve doctors,which means they are treated as sources of medical *** should treat patients *** educated and inarticulate patients need more help,care and ***'interest is always the priority,including,not to abuse doctors'power for personal gains,or to gain anything directly or indirectly from *** win a patient's trust,we have to understand him or her,his or her understanding about the illness."Professor Qi Fang(方圻)always repeated those views,which have profound implications(Fang,2002).

调频步进信号具有作用距离远、硬件实现简单的特点,在现代雷达目标识别中具有明显优势。该文推导了调频步进信号合成距离像的原理,分析了目标运动对合成距离像的影响。为了克服调频步进信号回波对目标运动敏感的缺陷,提出一种脉冲重复时间可变的调频步进信号,通过对脉冲重复时间预先设计来消除目标速度与频率的耦合效应,并通过回波对消技术消除目标加速度对合成距离像的影响,给出了该算法对脉冲重复时间的精度要求。仿真结果证明了算法的有效性。

In this paper, an underwater structure is modeled as a cylindrical shell with internal bulkheads, and closed by a truncated conical shell, and it consists of metal substrate and sound absorbing coating, whose FGM core is considered. Suppose the inner cavity and outer space of the structure are filled with air and fluid mediums, the mechanical response of the underwater structure is calculated with Galerkin method while the acoustic response is investigated by means of the Helmholtz integral. Some numerical examples are given and the effect of geometrical size and material parameters on mechanical and acoustic response is discussed.

目的探讨移植骨髓基质细胞(BMSCs)对永久性局灶性脑缺血大鼠脑室下区(SVZ)细胞增殖的影响及其增殖细胞类型分析。方法制作永久性局灶性脑缺血大鼠模型,分为空白对照组(MCAO)、PBS对照组(MCAO+PBS)和治疗组(MCAO+BMSCs),每组动物再分为脑缺血后7d和14d亚组。空白对照组不予处理,PBS对照组在脑缺血后1d移植PBS,治疗组在脑缺血后1d移植BMSCs。用Zausinger六分法检测神经功能恢复情况;注射5-溴脱氧鸟嘧啶核苷(BrdU)标记SVZ的新增殖细胞,免疫荧光双重标记检测新增殖细胞的类型。结果在脑缺血后7d和14d,与两个对照组相比,治疗组的神经功能评分较高,有显著性差异(P<0.05);脑缺血后14d,治疗组的大鼠患侧SVZ的BrdU阳性细胞较其余两组高,存在显著差异(P<0.05);免疫荧光双重标记显示,新增殖细胞表达神经元和星形胶质细胞的标志物,提示新增殖细胞为神经元和神经胶质细胞的混合体。结论BMSCs可以改善永久性局灶性脑缺血大鼠的神经功能,其机制可能与促进SVZ的神经细胞增殖有关。
