Parthenolide is extract from feverfew, it's main component is sesquiterpene, it is commanly used in west country and is mainly used to therapy skin infection, rheumatic disorder, migraine. But recent research indicate that parthenolide can regulate many pathway of signal in the cell, inhibit the cyclooxygenase, TNF-α, interleukin-1 expression induced by lipopolysaccharide in macrophage, inhibit the iNOS expression in human monocyt, inhibit the activity of NF-κB in Hela cell, inhibit the growth of tumor cell and can relieve the myocardial ischemical reperfusion injury and so on. But the invention research about the effection of parthenolide on the VSMC is very rare in the world, so we do some research about the effection of inhibition of parthenpolide on the proliferation of VSMC and the signal transduction mechanism.

小白菊内酯(parthenolide，又名Sesquiterpene lactone)是艾叶菊属黑叶母菊的提取物，主要成分是倍半萜烯内酯，西方国家较为常用，主要用于治疗皮肤感染、风湿病和偏头痛，但近年来发现小白菊内酯能调控细胞内多种信号途径，如抑制巨噬细胞中脂多糖诱导的Cox，肿瘤坏死因子α和白细胞介素-1的表达，能抑制人单核细胞中iNOS的表达，能抑制Hela细胞中NF-κB的活性，抑制肿瘤细胞的生长，同时能减轻心肌缺血再灌注损伤等，但小白菊内酯在VSMC中的干预研究目前国内外非常罕见，为了确切评价小白菊内酯对血管平滑肌细胞增殖的抑制作用及相关的信号转导机制，我们进行了一些研究。

Aside from pancreatic enzymes activiation and autodigestive process, recent investigations have established that the upregulation of inflammatory mediator are believed to be the critical steps in the progression of mild pancreatitis to severe pancreatitis. Tumor necrosis factor-, ThyomboxaneA2 ,ProstaglandinsI2 are all important inflammatory mediator. TNF-( is one of cytokines. It is important to the over-production of ICAM-1,VCAM-1, TXA2 andPGI2. The ICAM-1 and VCAM-1 mediate both leukocytes adhesion and migration through the endothelium into tissues to connect with injuried target cells. The TXA2 and PGI2 are the production of arachidonic acid. They are responsible for the tissue ischaemia.
