| 1 | 开心散乙醇提取物中远志皂苷的入血成分及体内代谢产物分析显示文摘目的:鉴定开心散60%乙醇提取物(KXS-60%E)及其血中移行成分中的远志皂苷类成分,分析大鼠体内远志皂苷类成分的代谢产物。方法:应用UPLC-TOF-MS技术,分析TOF-MS/MS给出的二级离子信息,结合液质联用工作站Mass Lynx v4.1分析软件及现有的文献数据库,鉴定KXS-60%E中远志皂苷类成分、灌服KXS-60%E后血清中的远志皂苷类成分及其代谢产物。结果:鉴定了KXS-60%E中14个远志皂苷类成分,主要为三萜型皂苷;鉴定了大鼠口服KXS-60%E后血中的5个原型皂苷类成分及4个代谢产物。结论:远志皂苷类成分及4个代谢产物可能是KXS-60%E潜在的活性成分及直接药效物质基础,这将有助于阐明开心散防治阿尔兹海默症的有效成分及作用机制。 | Reeju Maharjan Chiranjivi Thapa 汪娜 Ram Chaulagain 薛迪 贾永明 邓竹君 黄树明 刘学伟 | 2017 | 中国实验方剂学杂志2017，23，19： | 13 |
| 2 | Neuroprotective mechanism of Kai Xin San: upregulation of hippocampal insulin-degrading enzyme protein expression and acceleration of amyloid-beta degradation显示文摘Kai Xin San is a Chinese herbal formula composed of Radix Ginseng, Poria, Radix Polygalae and Acorus Tatarinowii Rhizome. It has been used in China for many years for treating amnesia. Kai Xin San ameliorates amyloid-β(Aβ)-induced cognitive dysfunction and is neuroprotective in vivo, but its precise mechanism remains unclear. Expression of insulin-degrading enzyme(IDE), which degrades Aβ, is strongly correlated with cognitive function. Here, we injected rats with exogenous Aβ42(200 μM, 5 μL) into the hippocampus and subsequently administered Kai Xin San(0.54 or 1.08 g/kg/d) intragastrically for 21 consecutive days. Hematoxylin-eosin and Nissl staining revealed that Kai Xin San protected neurons against Aβ-induced damage. Furthermore, enzyme-linked immunosorbent assay, western blot and polymerase chain reaction results showed that Kai Xin San decreased Aβ42 protein levels and increased expression of IDE protein, but not m RNA, in the hippocampus. Our findings reveal that Kai Xin San facilitates hippocampal Aβ degradation and increases IDE expression, which leads, at least in part, to the alleviation of hippocampal neuron injury in rats. | Na Wang Yong-ming Jia Bo Zhang Di Xue Maharjan Reeju Yan Li Shu-ming Huang Xue-wei Liu | 2017 | Neural Regeneration Research2017，12，4： | 11 |
