Berberine alleviates ovarian tissue damage in mice with hepatolenticular degeneration by suppressing ferroptosis and endoplasmic reticulum stress

引用

Journal of Integrative Medicine 2024年第4期22卷 493-502页

Objective:Hepatolenticular degeneration (HLD) is an autosomal recessive disorder that manifests as multiorgan damage due to impaired copper (Cu) metabolism. Female patients with HLD often experience reproductive impairments. This study investigated the protective effect of berberine against ovarian damage in toxic-milk (TX) mice, a murine model for ***:Mice were categorized into control group, HLD TX group (HLD group), penicillamine (Cu chelator)-treated TX group and berberine-treated TX group. Body weight, ovary weight and the number of ovulated eggs were recorded. Follicular morphology and cellular ultrastructure were examined. Total iron, ferrous iron (Fe2+) and trivalent iron (Fe3+) levels, as well as malondialdehyde (MDA), glutathione(GSH) and oxidized glutathione (GSSG), were measured in the ovaries. Western blot analysis was used to analyze the expression of proteins related to ferroptosis and endoplasmic reticulum (ER) ***:Ovarian tissue damage was evident in the HLD group, with a significant increase in ferroptosis and ER stress compared to the control group. This damage was inhibited by treatment with penicillamine,a Cu chelator. Compared with the HLD group, berberine increased the number of ovulations, and improved ovarian morphology and ultrastructure. Further, we found that berberine reduced total iron,Fe2+, MDA and GSSG levels, elevated GSH levels, decreased the expression of the ferroptosis marker protein prostaglandin-endoperoxide synthase 2 (PTGS2), and increased glutathione peroxidase 4 (GPX4)expression. Furthermore, berberine inhibited the expression of ER stress-associated proteins mediated by the protein kinase RNA-like ER kinase (PERK) ***:Ferroptosis and ER stress are involved in Cu-induced ovarian damage in TX mice. Berberine ameliorates ovarian damage in HLD TX mice by inhibiting ferroptosis and ER stress.

密文可逆信息隐藏技术可以在加密载体中利用冗余空间额外嵌入信息,在传输过程中保障载体和信息的隐私安全,载体接收者还可以实现无损地提取信息和恢复载体.3维网格模型作为新型的数字媒体,其文件结构与传统的图像等数字媒体存在着不同,并且在该领域的研究相对较少.如何提升模型的嵌入容量是目前需要解决的问题.将图像领域多个高有效位预测算法直接迁移到3维模型中应用时,由于数据的存储格式与图像媒体不同,使得算法的预测性能受到了限制.因此,提出了将顶点坐标值标准化处理,消除符号位带来的影响,提升了预测算法的性能.为了进一步减少无用的辅助信息,嵌入集顶点的筛选被加入实验中,成功地为有效载荷腾出空间.实验表明,提出的方法与现有方法相比,在保证无损和可分离地恢复模型与所嵌入的信息的同时,获得了最高的嵌入容量.

目的探讨小儿卵黄囊瘤的临床特点及预后影响因素。方法收集2010年1月至2018年8月在安徽省儿童医院就诊的卵黄囊瘤85例患儿临床特征、治疗和预后的临床资料。采用Kaplan-Meier法绘制生存曲线;采用单因素及多因素Cox比例风险回归模型分析患儿预后的影响因素。结果85例患儿中位年龄为20.5(0.03~166.6)个月,中位随访时间为62.1(1.5~133.1)个月,5年总体生存率为87.1%(95%CI:79.7%~94.5%),5年无进展生存率为79.8%(95%CI:70.6%~89.0%)。单因素Cox回归分析显示:生活地区、远处转移、延迟化疗、术前血清甲胎蛋白、术后2个月血清甲胎蛋白、复发均与其预后有相关性(P<0.05),是影响患儿生存的危险因素。多因素Cox回归分析显示,居住于农村地区(HR=7.830,95%CI:1.60~38.41,P=0.011)、延迟化疗(HR=5.323,95%CI:1.14~25.64,P=0.047)、术后2个月血清甲胎蛋白未降至正常(HR=15.704,95%CI:1.65~149.18,P=0.017)、肿瘤复发(HR=26.046,95%CI:3.03~224.07,P=0.003)是影响预后的独立危险因素。结论生活于农村地区、延迟辅助化疗、术后2个月内甲胎蛋白未恢复正常、肿瘤复发可能提示预后不良,需要根据生活地区、化疗意愿、治疗后持续监测甲胎蛋白与影像学表现,对卵黄囊瘤儿童进行个体化治疗和随访。
