为了探讨苦马豆素通过消化系统对家兔脾脏免疫功能和代谢的影响,将体重为(1.9±0.12)kg的24只家兔随机分成对照组与试验组,每组雌、雄各半。试验组家兔饲喂含有小花棘豆的自制颗粒饲料,饲喂苦马豆素剂量为2 mg/(kg·d),对照组家兔饲喂自制颗粒饲料中不含小花棘豆。所有家兔单笼饲养,自由饮水,每天观测并记录家兔的健康状态。在试验的第60天,采取所有家兔脾脏,对脾脏进行基于iTRAQ的定量蛋白质组学分析、生物信息学分析及关键蛋白质的Western blot验证。结果显示,所有试验组家兔均呈现明显的中毒现象。与对照组相比,共鉴定出315个与新陈代谢(81%)及免疫相关(15%)的差异表达蛋白质(>1.5倍或<1/1.5倍)。而且,苦马豆素中毒家兔脾脏细胞分解代谢处于激活状态,但其免疫反应处于抑制状态。说明苦马豆素抑制了家兔脾脏的免疫功能,激活了脾脏组织的分解代谢。

A general stochastic model of the atmospheric pressure at the ocean surface was proposed, in which the pressure variation was represented by a spectral decomposition through a random process of orthogonal increments. From the basic equations of ideal and incompressible fluid a set of perturbation equations up to second order had been derived and solved. The pressure variation in the flow field had been calculated using the explicit solutions obtained, and which demonstrated a clear relation between the atmospheric pressure and the one at the bottom of deep ocean. It can be seen that there is a part of the pressure variation which is not attenuating with the depth. The result had been compared with those of Longuet-Higgins and Kadota et al. and all previous results are contained in the solution given in this artice. The restriction on the previous works with regard to the probability law has been removed, and all conclusions are deduced without specific assumptions. The flexibility of the proposed model allows for further generalization and extension in the physical aspects and statistical treatment.

Interactive proof and zero-knowledge proof systems are two important concepts in cryptography and complexity theory. In the past two decades, a great number of interactive proof and zero-knowledge proof protocols have been designed and applied in practice. In this paper, a simple memorizable zero-knowledge protocol is proposed for graph non-isomorphism problem, based on the memorizable interactive proof system, which is extended from the original definition of interactive proof and is more applicable in reality. Keywords interactive proof - zero-knowledge proof - memorizable interactive proof - memorizable zero-knowledge proof This work was supported by the ministry of Science and Technology of China (Grant No.2001CCA03000), and the National Natural Science Foundation of China (Grant No.60273045).Ning Chen received his B.S. degree from Fudan University in 2001.

The current of the molecular motor model disturbed by random potentials, which involve the dichotomous and Ornstein-Uhlenbeck potentials, is studied using a finite-space correlation function. It is found that: (i) the amplitude and the correlation length of random potentials play opposing roles in the transport of the molecular motor model;(ii) a random potential with small amplitude and large correlation length is very useful in the molecular motor system.

在综述前人研究成果的基础上,选取国内外代表性的煤岩样品实验研究数据,分别对兰氏体积和兰氏压力的影响因素进行讨论。研究表明,煤岩成熟度(煤阶)、煤岩类型、温度、灰分和水分等都对煤岩吸附能力产生影响,其中煤岩成熟度是最重要的影响因素。研究认为:兰氏体积随煤岩成熟度呈现出了“U”形或“先升—后降—再升”变化趋势,反映了中煤阶吸附能力弱于低煤阶和高煤阶的现象,主要是煤岩成熟度影响孔隙结构,进而影响吸附能力的结果。煤岩类型对兰氏体积的影响是客观存在的,镜质体含量高,吸附能力趋于更强。灰分和水分与煤岩兰氏体积表现出复杂非线性负向关系,在实验研究中有所反映,在利用低煤阶数据分析中也有一定程度的识别。兰氏压力受煤岩成熟度(煤阶)的影响也十分显著,显示出随煤阶升高而降低的趋势。在低煤阶区,灰分或水分和镜质组含量的影响在一定程度上可以识别,但难以形成规律性认识,中高阶区则未反映出明显特点。
