Non-alcoholic fatty liver disease, especially nonalcoholic steatohepatitis (NASH), is a leading cause of cirrhosis and liver cancer worldwide;nevertheless, there are no Food and Drug Administration-approved drugs for treating NASH until now. Peroxisome proliferator-activated receptor alpha (PPARα) is an interesting therapeutic target for treating metabolic disorders in the clinic, including NASH. herpetrione, a natural lignan compound isolated from Tibetan medicine herpetospermum caudigerum, exerts various hepatoprotective effects, but its efficacy and molecular mechanism in treating NASH have not yet been elucidated. here, we discovered that herpetrione lessened lipid accumulation and inflammation in hepatocytes stimulated with oleic acid and lipopolysaccharide, and effectively alleviated NASH caused by a high-fat diet or methionine-choline-deficient diet by regulating glucolipid metabolism, insulin resistance, and inflammation. Mechanistically, RNA-sequencing analyses further showed that herpetrione activated PPAR signaling, which was validated by protein expression. Furthermore, the analysis of molecular interactions illustrated that herpetrione bound directly to the PPARα protein, with binding sites extending to the Arm III domain. PPARα deficiency also abrogated the protective effects of herpetrione against NASH, suggesting that herpetrione protects against hepatic steatosis and inflammation by activation of PPARα signaling, thereby alleviating NASH. Our findings shed light on the efficacy of a natural product for treating NASH, as well as the broader prospects for NASH treatment by targeting PPARα.

以处理难降解有机污染物对氯苯酚(4-CP)模拟废水的序批式好氧活性污泥系统为研究对象,探讨活性污泥在降解4-CP的过程中污泥有机毒性的形成与空间分布规律,以及污泥有机毒性随时间的变化趋势。处理组污泥用10 mg/L的4-CP模拟废水进行驯化。控制SBR系统的水力停留时间(HRT)和污泥停留时间(SRT)分别为12 h和20 d。结果表明,随着驯化时间的延长,处理组污泥毒性先升高后降低,最终达到稳定状态。在整个运行过程中,处理组污泥毒性始终高于对照组。4-CP的吸附与降解实验表明,污泥外层胞外聚集物(EPS)主要起吸附4-CP且向内层传递的作用,污泥有机毒性主要是由4-CP的降解过程引起,少部分由污染物吸附所致。

"银色浪潮"袭来的新形势下,我国传统的养老模式难以适应老年人对于养老服务需求的快速增长,如何解决这一矛盾已成为当前维护社会稳定和经济发展的重要任务。文章提出社区居家"医养结合"养老模式,从其概念、优势和特点出发,说明其作为解决当前养老供需矛盾的重要手段;并以我国社区居家"医养结合"养老模式的实践为根据,指出这种模式在实际运用过程中存在政府角色不明、社区主动性不高、社会企业参与度不高和非营利组织不成熟等支持不足的问题,运用社会支持理论和福利多元理论,构建以政府、社区、企业和非营利组织"四位一体"的社会支持体系,将危机转换成机遇。
