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。

NSE are reported to be useful diagnostic marker for lung cancer, neuroblastoma, melanoma, seminoma and in injury of central nervous system.

据文献报道，NSE含量测定可作为肺癌、成神经细胞瘤、黑素瘤、精原细胞瘤以及中枢精神系统损伤的诊断指标。

Methods: Eighty mice were randomly divided into high, middle, and low dosage groups which were orally given 1.5 g/kg, 0.75 g/kg, 0. 375 g/kg of ant powder respectively, twice a day for 10 days. A blank control group was set up which was given water instead. Body weight, thymus weight and spleen weight were measured. Thymus indexes and spleen index were calculated. Neutrophil phagocytose rate, Ea and Et rosette formation rate of T lymphocytes, and hemolysin titre were detected. QHS values were achieved with spleen cell mediated sheep red cell spectrophotometer quantitative assay.

根据黑蚂蚁的用药量将小鼠分成高、中、低剂量及空白对照组，黑蚂蚁粉给药量按小鼠体重1.5g/kg、0.75g/kg、0.375g/kg计算，连续10d灌胃给药后，测定各组小鼠的体重、胸腺和脾脏重量，计算胸脾指数；检测中性粒细胞的吞噬率、T淋巴细胞E花环形成率及小鼠的溶血素效价和脾细胞介导的羊红细胞分光光度计定量测定法。

Methods MTT was used to study the proliferation of A375 human melanoma cell. Tyrosinase activity was measured by zymologic method. The melanin was detected by its absorption at 475nm.

方法四甲基偶氮唑蓝法测定验方对细胞增殖的影响，用酶学方法测定对酪氨酸酶活性的影响，475nm比色法测定验方对黑素含量的影响。

Of this group, there were 8,800 deaths, 6,300 from melanoma and 2,500 from squamous cell carcinomas.

而在这组数据中，有8800人死亡，6300人有恶性黑素瘤，2500人患有鳞片细胞癌。
