目前不论学术研究中还是一般情况下,对"宗教法"一词大多存在不同的理解和运用。在法学研究的领域也缺乏专门、系统的解释和阐述;而在当前提议加快宗教立法、构建和谐社会的呼声此起彼伏的情况下,尤其需要先搞清楚"宗教法"这样一个词语是不是适合用于一部法律的名称。因此,作者就"宗教法"的概念进行了一些分析和阐释。"宗教法"一词来源于对西方"Religious Law"一词的翻译,本文介绍了历史上东西方对"宗教法"的理解,提出了新的定义。即宗教法可以定义为以宗教经典著作、宗教教义的精神为指导形成的调整特定社会关系或个人的行为或思想规范的总称。在理论上,任何宗教都可能有其宗教法,佛教法也是存在的。

太赫兹时域光谱技术(THz-TDS)结合主成分分析-线性判别分析(PCA-LDA)和支持向量机(SVM)用于正品大黄样品的鉴定。在时域测量41个大黄样品的太赫兹时域透射光谱,然后将这些时域信号转换成频域的吸收系数系数。根据样本的吸收系数建立了主成分分析-线性判别分析和支持向量机的定性分类模型,并对正品和非正品大黄样本的分类模型进行了交叉验证。模型的预测能力和稳定性使用自助拉丁配分进行评价,使用50次自助拉丁配分,配分数为4。使用主成分分析-线性判别分析和支持向量机均得到了满意的结果。提出的方法证明是一种方便、无污染、准确和无需化学处理的鉴定大黄样本的方法。该文提出的步骤可以应用于其他中草药分类和生产的质量控制。

Background:Huangqi Guizhi Wuwu decoction(HQGZWW)exhibits good effects when administered to treat multiple sclerosis(MS)and its animal model,experimental autoimmune encephalomyelitis(EAE).Understanding the precise mechanism of this decoction is thus *** on the findings of our previous study,the aim of the present study was to understand the role of antigen-specific CD8^(+)T-cells on the pathogene sis of MS/EAE when HQGZWW is administered as ***:Myelin oligodendrocyte glycoprotein(MOG);-induced mice were administered distilled water,prednisone,and high dose or low dose *** purified CD4^(+)and CD8^(+)T-cells were stimulated with the MOG;peptide,proliferation and cytokine secretion assays were *** establish the adoptive transfer EAE model,naive mice were injected with MOG;-CD8^(+)or CD4^(+)***:Significant improvements in EAE score and pathology were observed in the high dose HQGZWW and prednisone *** to the low dose HQGZWW and distilled water groups,lower antigen-specific re sponses,lower levels of interferon-gamma,and higher levels of interleukin(IL)-4 and IL-10 from CD8^(+)and CD4^(+)T cells were observed in the high dose HQGZWW and prednisone ***,the EAE score was observed to be similar between the high dose HQGZWW group and prednisone group;however,this finding was not observed in the low dose HQGZWW ***:Our findings suggest that high dose HQGZWW has similar effects on cell proliferation,cytokine secretion,and EAE score to prednisone,while low dose HQGZWW does not have such *** protective role of HQGZWW against EAE might thus depend on the Th2 cytokine secretion profile induced by either MOG;specific CD8^(+)or CD4^(+)T-cells.
