研究室概述：

研究方向1：慢性炎症与动脉粥样硬化和代谢性血管病变

动脉粥样硬化是当今世界上严重威胁人类健康的最常见的疾病，每年全世界约有1200万人死于动脉粥样硬化并发症。本室近十年来从寻找心血管疾病发病新的危险因子出发，曾在国际上最先报道了引起动脉粥样硬化发病新的独立危险因子高同型半胱氨酸血症（Hyperhomocysteinemia, HHcy）通过激活多种致炎的免疫反应，加速动脉粥样硬化和胰岛素抵抗伴发的血管病变的发生。目前就其分子发病机制正进行深入的研究。

研究方向2：内源性血管活性物质对心血管的保护作用及其机制

自稳态的维持是生命存在的基本条件，心血管系统的稳态失衡是各种血管损伤性疾病的共同发病基础。神经、内分泌和心血管旁/自分泌系统产生多种生物活性物质，对心血管结构和功能的稳态进行精密的调节。本室十几年来从寻找内源性拮抗心血管损伤的活性多肽及其网络调控出发，在国际上首先报道了降钙素基因相关肽家族的几种活性肽的炎症上调机制和心血管保护作用机制。目前正针对其内源性网络调控的保护机制进行深入研究。

研究方向3：细胞外基质及基质水解酶在血管重塑中的作用

基质的合成和降解参与了动脉粥样硬化斑块形成、斑块破裂以及血管再狭窄的发生和发展。本室研究集中在金属蛋白酶的新家族ADAMTS在上述心血管疾病中的作用。首先在国际上报道ADAMTS-7介导了血管损伤后再狭窄的发病过程。目前就其分子机制正进行深入研究。此外，还致力于研究细胞外基质蛋白对于维持血管细胞正常表型及对血管钙化形成的影响。

Research Description:

1. Chronic inflammation, atherosclerosis and metabolic vascular disorders. Atherosclerosis is the most common and fetal disease, 12 million people died of atherosclerosis and its complications each year. In recent 10 years, our lab focuses on seeking new risk factors of cardiovascular diseases. We have reported firstly in the world that hyperhomocysteinemia, the independent risk factor of atherosclerosis, accelerates the pathogenesis of atherosclerosis and insulin resistance concomitant vascular disorders. We are now approaching the related molecular mechanism.

2. Protection effect of endogenous vasculoactive substances on cardiovascular system and the mechanism. Homeostasis is the essential for life, disbalance of cardiovascular homeostasis is the common pathogenesis of vascular disorders. Many bioactive substances are synthesized by neural, endocrinal and cardiovascular para/autocrine system and regulate the homeostasis of cardiovascular structure and function precisely. For more than 10 years, our lab focuses on seeking the endogenous vasculoactive peptides antagonizing cardiovascular injury and the regulating network. We have reported firstly in the world that the CGRP superfamily could be upregulated by inflammation and protect cardiovascular system. We are now approaching the protecting mechanism of its endogenous network regulation.

3. Extracellular proteases play a key role during atherosclerosis and restenosis. The relevance of ADAMTS family members in cardiovascular disease is just now being addressed, but the precise effects and underlying mechanisms are poorly understood. Our primary interest is focused on the effect of ADAMTS-7 on the evolution and progression of atherosclerosis, as well on plaque rupture. Our

studies apply a combination of biochemistry, cell biology, and genetics to elucidate fundamental mechanisms that governing ADAMTS-7 activation and signaling, and to illuminate their pathophysiological impact during atherogenesis. Our studies demonstrate that ADAMTS-7 is transcriptional regulated by proatherosclerotic factors including inflammatory cytokines. ADAMTS-7 is required for VSMCs migration and intima thickening. Future studies will further explore potential possibility of ADAMTS-7 as a novel target for atherosclerosis and serum ADAMTS-7 level as biomarker for atherosclerosis progression.
