Pueraria lobata is one of the most important medicinal herbs used traditionally in China. According to Shanghan Lun(Treatise on Exogenous Febrile Disease), it has been used traditionally to relieve body heat,eye soring, dry mouth, headache associated with high blood pressure, and stiff neck problems. Modern studies in the 1970 s revealed that isoflavonoids extracted from P. lobata were the bioactive components of an herbal remedy namely Yufeng Ningxin Tablets for the treatment of patients after stroke. This article reviews recent application of P. lobota in the treatment of diabetics and in reducing alcohol drinking. In view of its low toxicity profile, P. lobota stands an excellent chance to be developed as a phytomedicine for treating human diseases.

绝经后骨质疏松症是更年期妇女的常见全身性骨代谢疾病,体内雌激素水平下降是其重要病因。激素替代疗法(HRT)虽然在多年的临床实践中有着良好和肯定的疗效,但其在提高妇科肿瘤发生率等方面具有明显的副作用。临床实践已经证明,多种妇科中药方剂、单味中药及中药植物雌激素样活性成分对骨质疏松症有确凿疗效且副作用小。其主要通过作用于靶组织、靶细胞的雌激素受体并进而影响其下游信号传导通路中骨代谢相关调节蛋白和因子的表达情况,达到对骨质疏松症的防治效果。同时,近年来雌激素相关受体的研究也为全面揭示中药及其活性成分抗骨质疏松症的作用机制提供了新的可能角度和途径。

既往研究已经表明,鼠尾草酚(carnoso1)具有一定的抗乳腺癌效应,但其ER亚型特异性调节和介导机制与该物质抑制细胞增殖效应的相关性尚不清楚。该研究利用雌激素受体(ER)阳性乳腺癌T47D细胞观察鼠尾草酚对细胞增殖活性的影响及其雌激素受体α,卢亚型特异性介导和调节机制。以ERα和ERβ特异性拮抗剂MPP,PHTPP为工具药,采用MTT细胞增殖实验观察鼠尾草酚对T47D细胞增殖的影响;检测T47D细胞增殖周期的变化。利用Western blot方法检测鼠尾草酚对T47D细胞ERα和ERβ表达情况的影响。研究发现,1×10^(-5)~1×10^(-7)mol·L^(-1)鼠尾草酚能够显著抑制T47D细胞增殖,该抑制作用可被ERα拮抗剂MPP增强、被ERβ拮抗剂PHTPP减弱;1×10^(-1),1×10^(-6)mol·L^(-1)鼠尾草酚可使T47D细胞增殖指数显著下降。Western blot检测结果显示1×10^(-5),1×10^(-6)mol·L^(-1)鼠尾草酚可使T47D细胞ERα和ERβ蛋白表达显著增加,并可明显提高ERα/ERβ。结果表明鼠尾草酚具有抑制ER阳性乳腺癌细胞增殖的作用,其效应是通过靶细胞雌激素受体,特别是ERβ途径实现的;同时,鼠尾草酚对靶细胞雌激素受体ERα和ERβ亚型的表达及其比例具有调节功能。
