野木瓜不同提取部位的镇痛抗炎作用研究

目的探讨野木瓜不同部位提取物的镇痛抗炎效果,并作有效部位筛选。方法采用热板法和乙酸扭体法实验研究不同部位提取物的镇痛作用;采用二甲苯诱发小鼠耳廓肿胀模型研究不同部位提取物抗炎作用。结果野木瓜不同部位提取物对小鼠热板致痛均有明显的镇痛作用,其中乙醚提取物镇痛效果最为明显。不同部位提取物对乙酸诱发小鼠腹腔剧烈疼痛的镇痛作用显著,其中乙醚和三氯甲烷提取物效果尤为显著。乙醚提取物对二甲苯致小鼠耳廓肿胀有显著的抑制作用,而其他部位提取物抑制作用不明显。结论乙醚提取物为野木瓜中镇痛抗炎的主要活性部位。     

Institutions,interests, and policy support: Experimental evidence from China

Policy support matters for the success of public policies. It is still unclear how governments can garner support for policies with high costs. Using a conjoint experiment in China, we demonstrate that governments can encourage policy support by offering institutional services and material interests to policy targets. In particular, citizens become more willing to support policies when governments timely disclose policy information and respond to and incorporate their voices in the policy design. Government subsidies in both the short and long runs also increase citizens' policy support. In addition, government transparency and long-run subsidies are complementary to enhancing policy support; the role of institutions is strengthened when citizens are exposed to severe policy problems.     

诚信契约：《一个循规蹈矩的少女的回忆》

西蒙娜·德·波伏瓦在其回忆录第一卷《一个循规蹈矩的少女的回忆》中叙述了自己的童年和少女时代。根据菲力普·勒热讷关于自传契约的理论，波伏瓦必须诚信叙事。然而诚信并不意味着言尽一切，所以必须有选择地围绕一个中心记述往事。通过这本书，我们可以了解到波伏瓦个性史的起源。回忆少女时代是波伏瓦拯救过去的方式，从而赋予了自己的生活以一定的连贯性。
