Inonotus obliquus， an edible and medicinal fungus， has proven to be beneficial for relieving body aging. Previous research has shown that Inonotus obliquus polysaccharide (IOP) can effectively reduce oxidative stress and alleviate photoaging in UVB-treated HaCaT cells. However， the underlying mechanism is still unclear. This study aimed to investigate the mechanism through which IOP mitigates skin photodamage by modulating mitochondrial autophagy through both in vivo and in vitro experiments. The results indicated that IOP alleviated the thickening of the stratum corneum and inflammatory infiltration caused by UVB radiation. Moreover， IOP effectively inhibited the mRNA expression of MMP1 and MMP3 to prevent collagen breakdown and decreased the expression of aging-related proteins (P53 and P21) and inflammatory factors (TNF-α and IFN-γ) in UVB-induced mice. Both in vitro and in vivo studies demonstrated that IOP increased Sirt3 expression， activated the Foxo3a/PINK1-Parkin pathway and enhanced mitochondrial autophagy to reduce photodamage. Additionally， IOP could regulate the gut microbes in photodamaged mice and increase the relative abundance of Clostridium＿XlVa， Desulfovibrio， and Barnesiella， which are important for protecting the intestinal barrier and alleviating intestinal dysfunction. These results provide a theoretical foundation for the use of IOP as a natural component to reduce skin photodamage.

从公益角度来看,期间损失责任是对生态环境使用利益损失的赔偿责任;从私益角度来看,期间损失责任是对私人的用益物权造成的使用损失或纯经济损失的赔偿责任。期间损失责任的公私二元属性使得,对同一期间损失标的可能同时存在公共索赔与私人索赔。目前对期间损失责任的认知局限于公益角度,这使得期间损失全部通过公益诉讼索赔,当存在私人可以索赔的期间损失时,即生重复索赔。为避免重复索赔,需调整期间损失的索赔机制,划清期间损失公共索赔的边界。期间损失公共索赔的边界可以以“公上去私”为原则,在公共索赔的基础上排除对私人用益物权造成的使用损失和私人可索赔的纯经济损失这两类私人索赔的范围,并通过实体规则、程序规则、技术规则的完善予以实现。以此构建的期间损失公共索赔边界将随纯经济损失的可赔偿性的变化而变化,将来存在进一步缩窄的可能。
