A slow beam extraction system using the RF-Knock Out method and 3rd-order resonance is adopted in the synchrotron of this facility. Eight sextupoles are used, four of them are for correcting the chromaticity and the rest for driving the 3rd-order resonance. In order to save the aperture of vacuum chamber, a 3-magnet bump is adopted during the extraction process. The extraction phase space map and the last 3 turns’ particle trajectory before extraction are given. The matching betatron functions with HEBT （high energy beam transport） are also presented.展开更多
目的:观察泽泻萜类化合物对ApoE基因敲除小鼠实验性动脉粥样硬化肝脏基底膜硫酸乙酰肝素蛋白多糖的调节作用。方法:将8周龄C57/BL小鼠12只设为正常对照组,8周龄ApoE基因缺陷小鼠36只随机分为3组:模型组、中药组、舒降之阳性对照组。正...目的:观察泽泻萜类化合物对ApoE基因敲除小鼠实验性动脉粥样硬化肝脏基底膜硫酸乙酰肝素蛋白多糖的调节作用。方法:将8周龄C57/BL小鼠12只设为正常对照组,8周龄ApoE基因缺陷小鼠36只随机分为3组:模型组、中药组、舒降之阳性对照组。正常对照组、模型组予0.9%生理盐水灌胃,给药组正常人每kg体重的10倍量灌胃90天后,全自动生化仪测定血清血脂含量,用免疫印记法测定各组肝脏基底膜硫酸乙酰肝素蛋白多糖的表达,用Quantity One 6.0软件进行光密度分析。结果:中药组、阳性对照药组与模型组比较,总胆固醇、低密度脂蛋白水平均明显降低。中药组、阳性对照药组肝脏基底膜HSPG表达与模型组比较明显上调,但与正常对照组比较则明显下调。结论:泽泻萜类化合物对apoE-基因敲除高脂饲料喂养所致动脉粥样硬化小鼠具有降低血清总胆固醇、低密度脂蛋白的作用,对该模型小鼠的肝脏基底膜HSPG表达有调节作用。展开更多
