Journal of Bionic Engineering 2017年第1期14卷 119-129页

Natural composites have inspired the fabrication of various biomimetic composites that have achieved enhancement on certain mechanical performance. Herein, a facial approach enabled by recent advances in polyimine chemistry has been developed to fabricate bio-inspired hard-soft-integrated copolymers from two polyimines （i.e. PI-H and PI-S） with hardness differential. Subsequent evaluations of multiple mechanical properties on the bio-inspired copolymers with PI-S contents of full-range variability （0 wt%-100 wt%） have revealed extremal transitions for friction coefficients, impact strengths and tensile moduli. More interestingly, the minimum points of friction coefficients show a deformation-resisting response toward the change of applied loads, but not for the altered sliding speeds, suggesting a more significant role of load in determining the optimal anti-friction composition of the hard-soft integrated copolymers. These trends have been further corroborated by scanning electron microscopy of the worn specimens. Together these results have demonstrated that full-range extremal tran- sitions exist on multiple mechanical properties for hard-soft-integrated copolymers, providing valuable insights to the design and fabrication of composite polymers for many applications. The polyimine-based approach outlined here also affords a convenient method to tune the ratio of two components in the copolymers within the full range of 0 wt%-100 wt%, enabling quick integration with high content variability.

Evidence for the existence of monkeys with spontaneous Parkinson’s disease (PD) has been lacking. Here,we screened macaque colonies at the Kunming Primate Research Center(Association for Assessment and Accreditation of Laboratory Animal Care(AAALAC) accredited), Kunming Institute of Zoology, Chinese Academy of Sciences, which has a large population of monkeys (>2400), to identify naturally occurring PD monkeys.

我国计划生育政策由"提倡一孩"向全面"提倡两孩"的调整,必然要求计划生育奖励扶助政策做出相应调整。计划生育奖励扶助政策调整,应当遵循科学衔接、公平公正、国家尽责、社会关注的原则,形成以国家为主导的社会保障机制,弱化乃至消除奖励扶助政策中的城乡差别、地区差别和民族差别,真正体现其国策地位和公平公正原则。计划生育奖励扶助政策的基本走向应当是由奖励"一孩家庭"转变为鼓励按政策生育。需要重点修订的内容,一是"双轨制",以新法实施为标志,实行"老人老办法,新人新办法";二是包到底,重点解决好历史形成的独生子女家庭和计划生育特殊家庭的实际困难;三是增重点,把解决伤病残独生子女家庭的实际困难放在重要位置。

目的探讨地塞米松对哮喘小鼠气道血管生成及血管内皮生长因子(VEGF)表达的影响。方法用鸡卵清蛋白(OVA)致敏和雾化激发建立慢性哮喘小鼠模型,实验分为对照组、哮喘组和地塞米松组。测定支气管肺泡灌洗液(BALF)中白细胞和嗜酸粒细胞(EOS)及活性VEGF表达的变化;行HE染色及VEGF、抗Ⅷ因子免疫组化染色,在显微镜下计数气管黏膜固有层、黏膜下层血管密度,采用医学图像分析软件测定支气管管壁厚度(WAt/Pbm)及肺组织切片中的血管数。结果哮喘组EOS计数明显升高,气管血管密度、WAt/Pbm及肺组织切片中的血管数明显增加,与VEGF的表达呈正相关。地塞米松组与哮喘组比较炎性反应减轻,气管血管密度、WAt/Pbm及肺组织切片中的血管数减少,VEGF表达减弱,与对照组比较差异有统计学意义(P<0.05)。结论 VEGF在哮喘小鼠模型气道及肺组织内过度表达,在气道血管生成过程中可能具有重要作用。早期地塞米松干预可降低哮喘模型的气道炎症,减缓气道血管生成的过程。

为了对抗CCD成像制导武器,采用激光辐照方式进行压制性干扰极为有效。由于距目标较远,难以保证激光束能够视场内入射进行饱和干扰,故实施激光视场外干扰。首先进行了视场外激光干扰VC-210B型CCD探测系统的实验,然后利用激光束通过光学系统时的衍射和散射概念,深入分析了视场外激光干扰CCD探测系统的原理,讨论了激光散斑对比度与入射角之间的关系。实验结果和分析结论表明:视场外激光可实现对CCD探测系统的有效干扰,这种干扰主要是由于CCD探测系统的结构对视场外激光的散射和衍射以及视场外激光散斑效应引起的。
