In this paper, we explore state-based potential games using the semi-tensor product of ***, applying the potential equation, we derive both a necessary and sufficient condition as well as a sufficient condition to verify whether a state-based game qualifies as a potential game. Next, we present two static equivalence conditions of state-based potential games. We then delve into dynamic equivalence. We propose a criterion that allows us to identify state-based games that are dynamically equivalent to state-based potential games and share similar dynamic properties. Ultimately, we introduce the concept of state-based networked evolutionary games. We provide a necessary and sufficient condition to ensure that a state-based networked evolutionary game can be classified as a state-based potential game.

【目的】研究大肠杆菌tRNA合成底物类似物4,6-二氨基-2-巯基嘧啶功能化的金纳米粒子(gold nanoparticles,AuNPs)对革兰氏阴性多药耐药细菌的抗菌特性。【方法】以4,6-二氨基-2-巯基嘧啶为表面配体合成AuNPs,采用肉汤稀释法测定其对4种临床分离的革兰氏阴性多药耐药细菌的最低抑菌浓度(MIC)。通过不同浓度AuNPs处理后经平板计数绘制不同菌株的时间-杀菌动力学曲线。以铜绿假单胞菌为代表菌株,采用激光共聚焦显微镜、透射电子显微镜和凝胶电泳分析AuNPs对细菌细胞组分的损伤。通过亚致死浓度反复诱导评估细菌对AuNPs的耐药性演化。并以MTT实验初步评估了AuNPs对哺乳动物细胞的生物相容性。【结果】4,6-二氨基-2-巯基嘧啶介导的AuNPs平均粒径为6.8nm,zeta电位为+38.4mV。该AuNPs对4种临床分离的革兰氏阴性多药耐药细菌均表现出时间和浓度依赖的抗菌活性,MIC值介于4–8μg/mL之间。抗菌机制研究显示AuNPs主要通过诱导细菌细胞膜损伤和DNA断裂导致细菌死亡。耐药性演化评估发现细菌在为期30d的反复诱导下也基本不会对该AuNPs产生耐药性。细胞毒性结果显示AuNPs对哺乳动物细胞具有良好的生物相容性,在浓度达到256μg/mL时正常肝细胞L02和正常肺细胞AT II的存活率仍高达85%以上。【结论】小分子介导的AuNPs对临床分离的革兰氏阴性多药耐药细菌具有较好的抗菌活性,在应对当前严峻的多药耐药细菌感染方面具有潜在的应用价值。
