目的:研究针刺对慢性不可预知应激小鼠焦虑行为与终纹床核(BNST)内垂体腺苷酸环化酶激活肽(PACAP)及其受体PAC1信号分子的影响,探讨针刺抗焦虑的PACAP中枢作用机制。方法:运用慢性不可预知应激(CUS)方法造模。选取神门、内关进行手针针刺30min/次,隔日1次,持续15d。运用高架十字迷宫检测小鼠焦虑水平,以ELISA法测定小鼠血浆皮质酮(CORT)的含量,利用免疫组化法检测小鼠BNST内PACAP、PAC1的表达。结果:与空白组比较,模型组OT%值显著降低(P<0.05),血浆CORT水平显著升高(P<0.01),BNST内PACAP表达显著减少(P<0.01);与模型组比较,针刺组OT%值、OE%值显著升高(P<0.05),血浆CORT水平显著降低(P<0.01),BNST内PACAP表达显著增加(P<0.01)。结论:针刺改善CUS小鼠焦虑行为可能与上调BNST内PACAP表达、降低HPA轴活性相关。

The sequence of the rice genome holds fundamental information for its biology, including physiology, genetics, development, and evolution, as well as information on many beneficial phenotypes of economic significance. Using a "whole genome shotgun" approach, we have pro-duced a draft rice genome sequence of Oryza sativa ssp. in-dica, the major crop rice subspecies in China and many other regions of Asia. The draft genome sequence is constructed from over 4.3 million successful sequencing traces with an accumulative total length of 2214.9 Mb. The initial assembly of the non-redundant sequences reached 409.76 Mb in length, based on 3.30 million successful sequencing traces with a total length of 1797.4 Mb from an indica variant cultivar 93-11, giving an estimated coverage of 95.29% of the rice genome with an average base accuracy of higher than 99%. The coverage of the draft sequence, the randomness of the sequence distribution, and the consistency of BIG-ASSEM-BLER, a custom-designed software package

中国散裂中子源(CSNS)已于2018年5月建设完工,随后进行了试运行.其中的反角白光中子束线(Back-n)可用于中子核数据测量、中子物理研究和核技术应用等多方面的实验.本文报道对该中子束的品质参数测量实验过程以及最终实验结果.实验主要采用中子飞行时间法,利用^(235)U,^(238)U裂变室和~6Li-Si探测器测量了中子能谱和中子注量率,又利用闪烁体-互补金属氧化物半导体探测系统测量了中子束斑的剖面,得到了该束线的初步实验测量结果.其中白光中子的全能谱测量范围eV—100 MeV,给出了不确定度分析;给出了中子注量率两个实验厅位置的满功率值;给出了白光中子在直径60 mm情况下的全能区束斑.通过与模拟结果的比较探讨了以上结果的合理性,并提出了改进计划.这些实验结果为以后该束线的核数据测量和探测器标定实验奠定了基础.

目前国内外的质子标定终端较少,且普遍为单能质子束流.基于中国散裂中子源的反角白光中子源的eV—200 MeV中子能量区间的白光中子束流,以及中子与氢的~1H(n, el)反应,可以获得宽能谱的能量连续次级质子.利用1 GSps采样率、12 bit的波形数字化获取系统采集探测器输出波形信号,通过对波形信号的分析,得到中子及反冲质子的飞行时间,进而得到反冲质子的动能.利用该方法得到的质子,为探测器质子标定等研究提供了新的研究平台.在该研究平台已经开展了带电粒子望远镜的标定实验.研究了CsI (Tl)探测器不同的信号读出方式对望远镜的DE-E二维谱、幅度-质子动能二维谱等粒子鉴别方法得到的粒子鉴别的效果,得到了较优的探测器信号读出方案.该研究为带电粒子望远镜的建设提供了实验依据,也说明了基于反角白光中子源的宽能谱质子标定的可行性.
