重楼作为我国传统的名贵中药材,主要分布在云南、广西、贵州等西南一带,具有清热解毒、消肿止痛、凉肝定惊的功效,治疗铁打伤痛、毒蛇咬伤、凉风抽搐等具有奇效,迄今已经有2000多年的应用历史。重楼皂苷Ⅱ结构上属于薯蓣皂苷,是重楼的主要活性成分之一,具有抗肿瘤、抗炎、抗病毒、抗菌、免疫调节、抗氧化、逆转多药耐药等多种药理活性,展现出良好的应用前景。其中,重楼皂苷Ⅱ的抗肿瘤作用受到广泛关注,其作用机制与抑制增殖、迁移和侵袭,诱导细胞周期阻滞、凋亡和自噬,抑制血管生成,调节肿瘤微环境等有关。药代动力学显示,重楼皂苷Ⅱ由于其溶解度低、吸收差、体内分布不理想、代谢慢等因素,导致其体内生物利用度低,严重限制其临床应用。近年来,重楼皂苷Ⅱ的不良反应报道增多,如具有较强的溶血活性,并对肝、肾、心肌、心血管细胞等产生明显细胞增殖抑制作用。以“重楼皂苷Ⅱ”“PolyphyllinⅡ”“Paris SaponinⅡ”为主要关键词,通过检索“中国知网”“维普”“万方”“PubMed”“Web of Science”“Elsevier SD”等中英文数据库,现从药理作用及其机制、药代动力学研究、不良反应3个方面对其研究进展进行综述,以期为重楼皂苷Ⅱ的深入研究和开发利用提供思路和参考。

The influence of Nb-V microalloying on the hot deformation behavior and microstructures of medium Mn steel(MMS)was investigated by uniaxial hot compression *** establishing the constitutive equations for simulating the measured flow curves,we successfully constructed deformation activation energy(Q)maps and processing maps for identifying the region of flow *** concluded the following consequences of Nb-V alloying for MMS.(i)The critical strain increases and the increment diminishes with the increasing deformation temperature,suggesting that NbC precipitates more efficiently retard dynamic recrystallization(DRX)in MMS compared with solute Nb.(ii)The deformation activation energy of MMS is significantly increased and even higher than that of some reported high Mn steels,suggesting that its ability to retard DRX is greater than that of the high Mn content.(iii)The hot workability of MMS is improved by narrowing the hot processing window for the unstable flow stress,in which fine recrystallized and coarse unrecrystallized grains are present.

Methane, an abundant one-carbon（C1） resource, is extensively used in the industrial production of vital fuels and value-added chemicals. However, current industrial methane conversion technologies are energy-and carbon-intensive, mainly due to the high activation energy required to break the inert C–H bond, low selectivity, and problematic side reactions, including CO2emissions and coke deposition. Electrochemical conversion of methane（ECM） using intermittent renewable energy offers an attractive solution, due to its modular reactor design and operational flexibility across a broad spectrum of temperatures and pressures. This review emphasizes conversion pathways of methane in various reaction systems, highlighting the significance and advantages of ECM in facilitating a sustainable artificial carbon cycle. This work provides a comprehensive overview of conventional methane activation mechanisms and delineates the complete pathways of methane conversion in electrolysis contexts. Based on surface/interface chemistry, this work systematically analyzes proposed reaction pathways and corresponding strategies to enhance ECM efficiency towards various target products, including syngas, hydrocarbons, oxygenates, and advanced carbon materials. The discussion also encompasses opportunities and challenges for the ECM process, including insights into ECM pathways, rational electrocatalyst design, establishment of benchmarking protocols, electrolyte engineering, enhancement of CH4conversion rates, and minimization of CO2emission.
