Background: Idiosyncratic drug-induced liver injury(IDILI) is a serious side effect of drugs, Epimedii Folium(EF) is unequivocally implicated in idiosyncratic liver injury onset, potentially due to its ability to perturb the NOD-like receptor family pyrin domain containing 3(NLRP3) inflammasome. Fructus Ligustri Lucidi(FLL), a frequently used medicinal combination with EF, has not yet been investigated for its ability to ameliorate EF-associated hepatotoxicity. Aims and Objectives: Study on the mechanism of compatibility of FLL to alleviate liver injury caused by EF. Materials and Methods: Western blot was used to determine the expression of related proteins, ELISA was used to detect the secretion of related inflammatory factors IL-1β, IL-18, IL-6 and TNF-α, liver injury indexes were detected and liver pathological tissue staining was used to evaluate the liver injury. Results: Our results demonstrated that EF exerted a particular augmenting effect on the stimulation of the NLRP3 inflammasome mediated by nigericin or ATP, whereas FLL suppressed the NLRP3 inflammasome stimulation. Furthermore, an equal EF to FLL ratio significantly reduced the stimulatory effects of EF. Moreover, EF has the potential to induce hepatic injury and augment pro-inflammatory cytokine synthesis in rats subjected to LPS. However, when combined with FLL, the detrimental effects of EF were mitigated. Conclusions: FLL possesses the capacity to attenuate EF-associated hepatotoxicity by suppressing EF-triggered NLRP3 inflammasome activation. Thus, FLL holds promise for improving the clinical safety profile of EF, shedding light on the potential of compatibility and detoxification theories in traditional Chinese medicine.

碳排放权交易市场作为推进美丽中国建设、实现降碳减污绿色发展的重要手段,成为当前研究的热点问题.为探究碳交易背景下华北地区试点区域及非试点区域碳代谢过程,以城市碳代谢理论为依据,采取投入产出分析和生态网络分析相结合的研究方法.结果表明,北京和天津作为早期交易试点区域,区域从2012年后呈现直接碳排放量稳步下降、隐含碳排放量缓慢增加趋势.试点产业部门直接排放量与隐含排放量变化趋势一致,其中煤炭开采和洗选业、石油和天然气开采业和非金属矿物制品业减排效应明显,而排放量较高的电力、热力的生产和供应业表现为增加趋势.部门隐含碳排放强度与隐含碳排放量变化趋势相似证实部门隐含增加值在交易过程中并未增加.高碳排放部门的隐含碳排放量主要由长度小于6的代谢路径所贡献,因此应重点关注部门间较短路径传递的商品或服务的“清洁化”.在交易政策实施以前,区域产业部门间跨区域贸易较少,表现为低碳排放产品交换;2012年以后,随着京津冀城市群协同发展以及华北地区不断构筑的区域经济发展新格局,促使区域间跨区域和跨部门贸易增加.以碳排放权交易制度为背景,构建识别系统内关键参与者及关键路径的方法体系,可为区域性政策实施及可持续发展提供科学的发展建议.
