Characterization of long-term natural outcome of chronic hepatitis B virus infections [PDF]
, 2016 慢性乙型肝炎病毒感染是世界重要的公共卫生问题，可以导致肝癌、肝硬化等终末期肝病，继而导致死亡。我国是慢乙肝高流行区，全国约有1.2亿的慢性HBV携带者，慢性乙肝患者约3000万例，HBV感染对我国国民健康造成严重威胁。本研究的主要目的在于研究自然人群慢乙肝感染者的长期转归及其相关因素，监测乙肝相关肝硬化和肝癌的发病率，并且研究成人接种乙肝疫苗对其新感染的保护以及终末期肝病发生的影响。有助于更加深入的了解和认识乙肝，并为预防和预测乙肝相关终末期肝病提供重要的数据和依据 ...

Coalition Opportunity Structures and Advocacy Coordination in Consensus and Majoritarian Democracies
Policy Studies Journal, EarlyView.ABSTRACT Research on advocacy coalitions suggests that belief homophily—the tendency of actors to coordinate based on shared policy beliefs—drives coalition formation. However, coalition opportunity structures, which are shaped by institutional contexts, may influence the extent to which belief homophily matters.

Topics as Outcomes: Modeling the Influence of Intergovernmental Grants on Policy Diffusion
Policy Studies Journal, EarlyView.ABSTRACT Intergovernmental grants stimulate the diffusion of policy reforms, as the federal government provides states with a financial incentive to adopt policies aligned with federal priorities. Less is known about the extent to which these grants also stimulate horizontal diffusion across states.

血管紧张素转换酶、内皮型一氧化氮合酶和载脂蛋白E基因多态性与冠心病的相关性
Zhongshan Daxue xuebao. Yixue kexue ban, 2006 [目的]研究血管紧张素转换酶（ACE）基因插入/缺失多态性、内皮型一氧化氮合酶（eNOS）基因G894T多态性和载脂蛋白E（ApoE）基因多态性与冠状动脉粥样硬化性心脏病（冠心病）的关系.[方法]应用基因芯片技术分析133例冠心病患者和122例对照者ACE、eNOS和ApoE基因多态性,对比两组基因型及等位基因频率.[结果]冠心病组ACE DD基因型频率比对照组显著升高,28.6% vs 13.1%,P＜0.01,ACE基因多态性与冠心病危险性相关.两组eNOS和ApoE基因型频率差异无统计学意义（P ...

The Crosstalk and Regulation of Nur77 、RXRα and Cancer [PDF]
, 2012 核受体是真核细胞生物体内一类重要的蛋白质，在机体正常生命活动过程中发挥着极其重要的作用；然而，核受体表达和功能的异常会导致严重的人类疾病。这里，我们主要研究了两种核受体Nur77和RXRα在肿瘤发生中的作用及其机制。 在第一章中，我们主要研究了孤儿核受体Nur77在结肠癌发生中的作用及其调控。孤儿核受体Nur77属于核受体超家族的重要一员，易被诱导表达。研究表明，Nur77在多种人类肿瘤中高表达，提示它与肿瘤发生紧密相关；然而，其潜在的调控机制及生物学功能尚不清楚。在本章中 ...

A New Type of Spacer Oligonucleotide Typing for Mycobacterium Tuberculosis Complex and Clinical Evaluation [PDF]
, 2016 结核病是当今世界范围内对人类健康最具威胁的传染性疾病之一，具有潜伏感染的特点，因此追踪传染源和查证传播途径是长期困扰结核病流行病学研究的一个问题，也是分子流行病学要解决的首要问题。基因分型技术是分子流行病学研究的一个有力工具，在研究结核病传播规律方面有着不可替代的优势。一个理想的基因分型技术应当具备简便、快速、结果可在不同实验室间进行比较等特点。本论文基于探针熔解曲线分析技术，建立新型的快速结核分枝杆菌分型体系，并评价其临床应用。论文内容如下： 第一章为绪论，首先概述了结核病目前的流行情况 ...
