吗啡依赖鼠成瘾相关脑区腺苷酸环化酶的变化

目的观察吗啡依赖鼠成瘾相关脑区腺苷酸环化酶的变化,探讨成瘾相关脑区腺苷酸环化酶的变化与吗啡依赖机制的关系。方法建立吗啡依赖大鼠模型,应用酶组织化学的方法对吗啡依赖鼠七个相关脑区腺苷酸环化酶的变化进行观察,用图像分析系统测定其灰度值,并进行统计学处理。结果吗啡依赖组脑区腺苷酸环化酶含量升高。结论吗啡成瘾相关七个脑区腺苷酸环化酶含量随吗啡依赖时限的延长有增加的趋势,结果提示吗啡依赖机制与特定脑区腺苷酸环化酶的含量变化有密切关系。进一步揭示AC/cAMP-PKA系统上调与吗啡成瘾机制的关系。     

中国成功解决民族问题的道路

我国是一个多民族的国家,正确处理民族问题至关重要。坚持民族平等、民族团结和民族区域自治,贯彻落实以人为本、全面、协调、可持续的科学发展观,促进各民族共同团结奋斗、共同繁荣发展,是适合中国国情的、具有中国特色的解决民族问题的正确道路。     

双重文化构建的回族婚姻--云南通海县纳家营村回族婚姻考察

在异彩纷呈的中国少数民族婚姻状况中,回族的婚姻个性鲜明而独特。由阿拉伯世界移植到中华大地上的阿拉伯—伊斯兰文化与中国本土的汉文化结合起来的复合文化,激活并锻造出的回族婚姻形态,以中国汉文化婚姻为基本理念,以浓郁的伊斯兰宗教文化为框架整合,是人类学语境中的一种特殊"婚姻话语"系统。在当代农村回族婚姻的走势中,由于导入了新的文化因子,及现代强势文化的冲击和经济发展浸润性的影响,传统而相对单纯的回族婚姻过程裂变为相对复杂的婚姻形态。考察纳家营村回族婚姻变迁,可以客观地解读回族社会结构嬗变的主流缘由。     

抗日战争前后中国共产党在回族地区民族区域自治的政策与实践

抗日战争前后是中国共产党解决民族问题的纲领政策发生重大转变的历史时期，同时也是民族区域自治制度孕育和初步成形并付诸实践的历史阶段。民族区域自治作为我国解决民族问题的总制度，是马克思主义民族理论与中国国情相结合的产物。     

欠发达区域创新体系的功能缺陷与战略对策初探

区域创新体系的功能是欠发达区域经济发展最重要的能力因素。我国欠发达区域创新系统虽然已从计划主导型系统向市场主导型系统转变，具有区域特色的新型区域创新系统正在形成，但区域创新体系还存在诸多功能缺陷。     

产业转移承接对落后地区旅游产业发展的影响分析——以广西贺州为例

现阶段的广西在承接我国东部地区产业转移的过程中，首先可利用广西的特有区位和特有资源，将区域发展战略上升为国家战略，从而为广西经济发展和产业演进提供有效的融发器。其次，由于广西的旅游资源十分丰富，因此积极发展旅游业不仅有助于强化对东部发达地区产业转移的承接，而且东部发达地区的产业转移在相当程度上也会促进产西旅游业自身的发展，实践中这一点在广西贺州旅游产业的发展过程中就表现得十分明显。     

噻环乙胺及小型猪复合麻醉剂(XFM)对大鼠不同脑区单胺类神经递质的影响

Wister大鼠84只,先随机抽取12只为对照组,其余随机均分为噻环乙胺组和XFM组,每组又随机均分为麻醉组、恢复Ⅰ组和恢复Ⅱ组3个亚组。采用荧光分光光度法分别测定各组大鼠脑区内去甲肾上腺素(NE)、多巴胺(DA)和5-羟色胺(5-HT)的含量。结果显示,噻环乙胺及XFM均使麻醉组大脑皮层、海马和丘脑内NE和DA的含量显著降低,5-HT的含量显著增加(P0.01);恢复Ⅰ组和恢复Ⅱ组中上述各脑区内NE、DA、5-HT含量均显著恢复;麻醉全过程中,小脑和脑干内NE、DA、5-HT含量均无显著变化。结果表明,噻环乙胺及XFM的中枢麻醉作用可能与降低大脑皮层、海马和丘脑内NE和DA,同时增加5-HT的含量有关。     

Introduction to the special section: minority politics and the territoriality principle in Europe

Territorial arrangements for managing inter-ethnic relations within states are far from consensual. Although self-governance for minorities is commonly advocated, international documents are ambiguously formulated. Conflicting pairs of principles, territoriality vs. personality, and self-determination vs. territorial integrity, along with diverging state interests account for this gap. Together, the articles in this special section address the territoriality principle and its hardly operative practice on the ground, with particular attention to European cases. An additional theme reveals itself in the articles: the ambiguity of minority recognition politics. This introductory article briefly presents these two common themes, followed by an outline of three recent proposals discussed especially in Eastern Europe that seek to bypass the controversial territorial autonomy model: cultural rights in municipalities with a “substantial” proportion of minority members; the cultural autonomy model; and European regionalism and multi-level governance.

Natural population movement and marriage restrictions and hindrances in Styria in the 17th to 19th centuries

To marry has never been an egalitarian option or everybody's wish. There have always been calculations or considerations, structural or individual hindrances and even societal restrictions for individuals to get married despite wishing to do so. Without any doubt and apart from the debate on determination or love and free choice in former times, to marry has always been a societal event, a mutual relationship between personal wishes and societal environmental expectations.

And apart from all the debates on paradoxes in modernization processes, it is clear that in pre-modern times societal marriage restrictions were widespread.

It is very unlikely that people should have been forbidden to marry because they should not have sexual contacts, just for morality reasons. The keys have been considerations and calculations on reproductivity, economic and social resources, social and human capital. This paper deals with aggregated vital data from four parishes in Styria, Austria, covering the outgoing 17th century until the end of the 19th century, in order to detect hints of marriage restrictions.

The paper proves the well-known variety of marriage systems in pre-industrial and pre-modern times. It supports the idea that the presence of marriage restrictions hindered population growth, but the absence of such restrictions did not automatically foster more societal transparency and developmental chances in a modern sense, as mortality and inequality were very strong factors in pre-modern agrarian societies. In the end, the question of marriage restrictions was apparently posed and answered by privileged groups.
