白芍总苷为白芍的有效部位,主要含芍药苷、芍药内酯苷等活性成分,具有广泛的药理作用,尤其是近年来对白芍总苷的保肝作用开展了大量的药动学和药效学研究,但还未见其相关产品进入市场。笔者综述了近十几年来白芍总苷保肝作用的药动学和药效学研究进展,以期为白芍总苷保肝作用产品的研究开发和临床合理应用提供参考。白芍总苷在体内的吸收、分布、代谢和排泄的药动学特性比较明确,肝损伤疾病能够显著影响其体内代谢过程。白芍总苷具有抗急性肝损伤、非酒精性脂肪肝、慢性肝纤维化和抗肝癌等多种保肝作用。但现有研究还未能完全阐明白芍总苷的保肝作用机制及其体内过程,肝损伤如何影响白芍总苷的体内代谢、其多靶点整合调节的作用机制需要进一步深入研究,同时应开展其保肝作用的药动学和药效学相结合研究。

The exploration of component states for optimizing maintenance schedules in complex systems has garnered significant interest from ***,current literature usually overlooks the critical aspects of system flexibility and *** implementation of system reconfiguration can effectively mitigate system downtime and enhance production *** study proposes a dynamic condition-based maintenance policy considering reconfiguration for reconfigurable systems.A double-layer decision rule was constructed for the devices and *** achieve the best overall maintenance effect of the system,the remaining useful life probability distribution and recommended maintenance time of each device were used to optimize the concurrent maintenance time window of the devices and determine whether to reconfigure them.A comprehensive maintenance efficiency index was introduced that simultaneously considered the maintenance cost rate,reliability,and availability of the system to characterize the overall maintenance *** reconfiguration cost was included in the maintenance *** proposed policy was tested through numerical experiments and compared with different-level *** results show that the proposed policy can significantly reduce the downtime and maintenance costs and improve the overall system reliability and availability.
