Nowadays, the demand of people for hair coloring is on the rise. The hair dyes used in the market of our country are mostly chemical hair dye. The research and application of natural plant dyes, which extremely rich in resources and without pollution, have become more and more popular. At the same time, the development of natural plant hair dye is imperative under the constant development of health and environmental *** this thesis, the best extraction condition of balsamine pigment was confirmed by the single factor analysis as follows: ethanol 50%, solid-liquid ratio 1:40, 60 min, temperature 65 ℃. Then the extracted staining of impatiens pigment was used for hair dye. The dyeing properties of balsamine gigment were investigated in terms of temperature, time and so on. The best dyeing condition of balsamine pigment was confirmed by the single factor analysis and orthogonal test method as follows: 60 min, temperature 65 ℃, FeCl as dye mordant, the p H value of 7.

阿尔茨海默病(Alzheimer’s disease,AD)是一种进行性、破坏认知与记忆功能的持续性神经退行性疾病.它的主要病理特征是以β淀粉样蛋白(β-amyloid protein,Aβ)沉积和Tau蛋白过度磷酸化形成神经原纤维缠结(neurofibrillary tangle,NFT)为主,是一种日益严重的全球健康性问题.过氧化物酶体增殖物激活受体(peroxisome proliferators-activated receptor,PPAR)是在中枢神经系统(CNS)中表达,调节能量代谢、神经传递、氧化还原稳态、线粒体功能等生理过程的一种核受体. PPARα作为其中一个亚型,在AD控制突触可塑性和调节神经元认知功能中有重要作用,说明PPARα是治疗AD的一个很有前途的靶点.这篇综述探讨了Aβ、氧化应激、神经炎症、脂质代谢在AD中的意义,以及PPARα的潜在价值及其在AD中的作用,揭示了未来PPARα作为AD治疗靶点的可能性.

伴随知识经济的快速发展,知识产权垄断的危害日益严重,迫切需要反垄断法予以规制。但产生并发展于工业经济时代的现有反垄断法,并无直接适用于知识产权垄断的具体规则,各国普遍尝试采用延伸法律解释或类推适用的方法,将现有反垄断法规则适用于知识产权垄断,但无论在理论上还是在实践中都遇到了严重的法律困惑和障碍。2007年8月我国颁布的《反垄断法》虽然规定知识产权垄断应受该法规制,但同样未解决"如何"规制的问题。因此,在反垄断法中构建新的知识产权垄断法律控制制度是解决知识经济条件下知识产权垄断问题的重要途径,而法哲学上的权力限制理论、知识产权法上的利益平衡理论和反垄断法上的竞争理论则为这一新制度的建立与运行提供了理论依据。
