  研究方向:

  本研究室以严重高脂血症及其相关的疾病为研究对象。高脂血症是中国改革开放近30年来发病率增高最快的疾病之一,根据卫生部最新公布的资料(2007. 7),目前在中国的患病人数已经达到1.6亿。其引起的心脑血管疾病现与西方国家一样,超过了恶性肿瘤成为危害国人生命健康的头号杀手。

  我们应用分子生物、细胞生物及基因改造动物模型,并收集临床有关病例和家系,开展了从基础到临床对严重高脂血症的研究。在国内外以高胆固醇为主要研究方向的形势下,我们扬长避短,根据自己的优势和中国人高甘油三酯血症发病率高的特点,以多学科(心血管、消化、神经、纳米技术)的国内外合作为基础,开展了具有特色的严重高甘油三酯血症的研究项目,发表了一系列的研究论文,获得了2007年北京国际心血管病论坛“有影响的心血管论文奖”、2006年北京大学医学部“优秀SCI论文”和基础医学院“走向世界优秀论文”等奖励。

  具体的研究方向包括:

  一、 严重高甘油三酯血症及其所致多器官损害的机制研究

  1.   严重高甘油三酯血症的自发性动脉粥样硬化及其机理:

  2.   严重高甘油三酯血症导致的急性胰腺炎及其机理:

  3.原发性LPL缺陷和严重高甘油三酯血症的中枢神经系统损伤及其机理:

  4.糖尿病与严重高甘油三酯血症的关系研究

  5.高甘油三酯血症的血液流变学异常及血凝障碍

  6.高甘油三酯血症与肾脏损伤关系的研究

  二、 其它相关研究方向:

  1.利用泡沫细胞模型和联合性高胆固醇/高甘油三酯小鼠开展的降脂药物筛选。

  2.树枝状纳米粒子基因载体的研究。

  3.高脂血症的大动物模型研究。

  4.微流芯片技术在脂蛋白代谢研究中的应用。

  

  Research Description:

  The research of our laboratory focuses on severe dyslipidemia and related diseases. Dyslipidemia has been one of the most prevailing diseases in recent years in China. According to the newly released online data by the Ministry of Health, nearly 160 million Chineses suffer from dyslipidemia currently. As it is in the western countries, atherosclerotic vascular diseases associated with dyslipidemia, exceeding malignant tumors, have become the No.1 killer in China.

  We developed research programs on severe hypertriglyceridemia, one of the most common forms in dyslipidemia, by basic and clinical approaches., including:mechanisms of severe hypertriglyceridemia induced multiple organ injury; development of gene-modified large animal models with hyperlipidemia, application of microfluidic chip in lipoprotein metabolism.
