可再分散的槲皮素纳米晶自稳定Pickering乳液冻干粉的制备

引用

解放军药学学报 2022年第2期35卷 100-105页

作者：王哲车智慧胡菲沈成英戴博申宝德袁海龙成都中医药大学药学院四川成都611137 空军特色医学中心北京100142 江西省人民医院江西南昌330004

目的以槲皮素(QT)为模型药,制备一种可再分散的槲皮素纳米晶自稳定Pickering乳液冻干粉(quercetin nanocrystals self-stabilized Pickering emulsion lyophilized powder,QT-NSSPE-LP)。方法采用高压均质法联合探头超声法制备QT-NSSPE,随后通过冻干技术实现其脱水固化得到QT-NSSPE-LP。以外观性状、复溶粒径和再分散指数(RDI)为评价指标,采用单因素试验筛选出QT-NSSPE-LP的优化处方,对优化条件得到的QT-NSSPE-LP进行表征和体外溶出评价。结果得到的QT-NSSPE-LP复溶粒径为(19.55±O.29)Mm,RDI为1.231±0.019;SEM和荧光显微镜结果表明冻干和再分散过程并未破坏QT-NSSPE-LP的形态结构。X-射线衍射结果表明QT-NSSPE-LP中QT的结晶度比原料药降低。体外溶出显示QT-NSSPE-LP的溶出度显著高于QT原料药。结论QT-NSSPE的固化可以通过冻干技术制备,能较好地保留Pickering乳液的形态结构和性质,可以为QT的进一步开发提供参考。

目的比较砂炒和醋炙炮制工艺对波棱瓜子有效成分、腹泻及保肝作用的影响。方法采用HPLC法分析波棱瓜子经砂炒(或)醋炙前后有效成分波棱甲素与波棱素的含量差异;以稀便率和腹泻指数评价砂炒和醋炙对波棱瓜子总木脂素致泻作用的影响;以CCl4急性肝损伤模型评价砂炒和醋炙对波棱瓜子总木脂素保肝作用的影响。结果波棱瓜子经砂炒(或)醋炙后波棱甲素含量分别降低40.9%和12.0%(P0.05)。在给药第4、6天,砂炒和醋炙波棱瓜子总木脂素高、中剂量组小鼠的稀便率和腹泻指数显著低于同剂量的生品组(P<0.01或P<0.05);不同炮制品波棱瓜子总木脂素高、中剂量组均能显著抑制CCl4致肝损伤小鼠血清中ALT、AST水平的升高(P<0.01或P<0.05);与同剂量的生品波棱瓜子总木脂素组相比,醋炙波棱瓜子总木脂素各组小鼠AST、ALT水平无显著差异,而砂炒波棱瓜子总木脂素高、中剂量组小鼠ALT、AST水平显著升高(P<0.05)。结论砂炒和醋炙均可有效缓解波棱瓜子总木脂素的腹泻作用,但砂炒后波棱瓜子总木脂素的保肝降酶作用下降,醋炙对波棱瓜子总木脂素的保肝降酶作用无显著影响。就缓解腹泻和保肝降酶作用而言,醋炙工艺优于砂炒工艺。

Exit options sustain altruistic punishment and decrease the second-order free-riders, but it is not a panacea

引用

Science China(Information Sciences) 2025年第1期68卷 278-291页

作者： Chen shen Zhao SONG Lei SHI Jun TANIMOTO Zhen WANG Faculty of Engineering Sciences Kyushu University School of Statistics and Mathematics Yunnan University of Finance and Economics School of Computing Engineering and Digital Technologies Teesside University School of Artificial Intelligence OPtics and Electro Nics (iOPEN) Northwestern Polytechnical University

Why do humans punish free riders at their own expense? This behavior represents an evolutionary puzzle in human societies. This study explores the role of exit strategies in fostering altruistic punishment within evolutionary game theory. We extend the traditional prisoner's dilemma model by incorporating exiters, players who opt out for a small payoff while nullifying their opponent's payoff, and altruistic punishers who cooperate and punish non-cooperators. Our findings indicate that in well-mixed populations, exiters destabilize defection but do not promote altruistic punishment. In social networks, however,exiters enable altruistic punishment via cyclic dominance among altruistic punishers, defectors, and exiters. Notably, this cyclic dominance is sensitive to exit payoffs; adjustments can lead to cyclic dominance of non-punishing cooperators, defectors, and exiters, or to a bi-stable state between these two types of cyclic dominance. These results highlight the nuanced impact of exiters on altruistic punishment, emphasizing the need for careful incentivization of exit behavior. While exiters can support altruistic punishment in networked populations, their effectiveness is not a panacea and is highly sensitive to exit payoffs, indicating limits to the voluntary participation mechanism.
