目的:探讨慢性阻塞性肺疾病(COPD)模型大鼠及化痰降气胶囊治疗后影像学的变化.方法:采用气管内注入脂多糖加熏香烟复合刺激法复制大鼠COPD模型.治疗组4周后给药,6周后各组摄片.结果:呼吸频率各组相比,差异有显著性(P<0.05或P<0.01);各组横膈前肋、横膈后肋、肋间隙积分比较,差异有显著性(P<0.01);横膈前肋积分,模型组与治疗组相比,差异有显著性(P<0.05).结论:COPD大鼠有明显的肺气肿影像学表现,化痰降气胶囊对COPD大鼠的影像学有较为明显的改善作用. 相似文献

In recent years, a widespread consensus has emerged about the necessity of establishing bridges between quantitative and qualitative approaches to empirical research in political science. In this article, we discuss the use of the synthetic control method as a way to bridge the quantitative/qualitative divide in comparative politics. The synthetic control method provides a systematic way to choose comparison units in comparative case studies. This systematization opens the door to precise quantitative inference in small‐sample comparative studies, without precluding the application of qualitative approaches. Borrowing the expression from Sidney Tarrow, the synthetic control method allows researchers to put “qualitative flesh on quantitative bones.” We illustrate the main ideas behind the synthetic control method by estimating the economic impact of the 1990 German reunification on West Germany. 相似文献

The core concern of this article is derived from my personal experience of being stopped and questioned at Heathrow Airport on 28 March 2012 for possession of “suspect materials”: academic books on terrorism. I seek to utilise this experience to reflect on how logics of counterterrorism can become manifested in bizarre and prejudicial ways, and how autoethnography provides a unique means to articulate human experiences of such logics. I further utilise my experience to reflect on the dynamics of academic privilege, which often flourish at the expense of the voices of “ordinary citizens”, and argue that autoethnography can be embraced as an empowering form of self-expression through which “ordinary citizens” might de-subjugate themselves from the margins of academia towards an emancipatory ideal wherein the lived experiences of such citizens occupy a substantial space in academic and popular understandings of (counter)terrorism. 相似文献

Both the columnar‐thin‐film (CTF) and the vacuum‐metal‐deposition (VMD) techniques for visualizing sebaceous fingermarks require the deposition of a material thereon in a vacuum chamber. Despite that similarity, there are many differences between the two techniques. The film deposited with the CTF technique has a columnar morphology, but the film deposited with the VMD technique comprises discrete islands. A split‐print methodology on a variety of fingermarked substrates was used to determine that the CTF technique is superior for developing fingermarks on clear sandwich bags and partial bloody fingermarks on stainless steel. Both techniques are similar in their ability to develop fingermarks on glass but the CTF technique yields higher contrast. The VMD technique is superior for developing fingermarks on white grocery bags and the smooth side of Gloss Finish Scotch Multitask? tape. Neither technique worked well for fingermarks on black garbage bags. 相似文献

Much of the attention surrounding local climate protection in the United States is associated with two networks: ICLEI Local Governments for Sustainability's Cities for Climate Protection and the U.S. Conference of Mayors’ Climate Protection Agreement (MCPA). However, the impact of these networks on member‐city actions has not been clearly established. This paper examines whether, and to what extent, participation in climate networks leads to the implementation of greenhouse gas (GHG)‐reducing policies, above and beyond what would have been done in their absence. To account for the possibility that cities which join climate networks are systematically different from those that do not and control for self‐selection induced bias, three statistical techniques—propensity score matching, Heckman full information maximum likelihood, and instrumental variables—are employed to estimate the “treatment effect” of participation. Results suggest that impact is network specific: ICLEI membership causes small to moderate increases in cities’ GHG‐relevant activity, whereas the MCPA has no such effect. The characteristics of each network are evaluated in light of these findings. 相似文献

相继出土的甘肃居延汉简、湖北江陵张家山汉简等竹简填补了对西汉初期法律制度研究的空白.近十年来,张家山汉简《二年律令》刑罚的研究主要集中于对刑罚体系研究和具体刑名考证为内容的刑罚法律制度的研究,对刑罚适用一般原则和具体刑罚的适用原则为内容的刑罚适用方面的研究,以及汉初刑罚法律思想的研究.不足之处在于对刑罚的执行和刑罚的消灭制度研究不够;与同时期的其他简牍文献的比较研究尚且不够,并且对一些问题必须重新审视并考证研究. 相似文献
