背景:多囊卵巢综合征患者体内高密度脂蛋白发生了部分氧化修饰,而氧化修饰高密度脂蛋白与排卵障碍的关系及其机制尚不清楚。目的:探讨氧化修饰高密度脂蛋白对卵巢颗粒细胞凋亡的影响,并分析其可能的作用机制。方法:构建多囊卵巢综合征大鼠模型,取心脏血并分离血清,进一步分离高密度脂蛋白,采用高密度脂蛋白炎症指数、丙二醛水平和脂蛋白琼脂糖凝胶电泳法检验其氧化程度。分离正常大鼠卵巢颗粒细胞,分别给予模型大鼠血清分离的高密度脂蛋白和氧化修饰高密度脂蛋白处理,CCK-8法检测细胞活力,流式细胞术检测细胞凋亡,h2DCF-DA染色检测活性氧生成水平,Western blot检测p38信号活性。卵巢颗粒细胞分别给予活性氧抑制剂N-乙酰半胱氨酸(NAC)和四甲基哌啶(Tempol)和p38抑制剂SB203580预处理后,再给予氧化修饰高密度脂蛋白处理,然后检测细胞凋亡、活性氧生成和p38信号活性。结果与结论:多囊卵巢综合征模型大鼠血清中高密度脂蛋白部分发生氧化修饰。模型大鼠血清分离的高密度脂蛋白和氧化修饰高密度脂蛋白抑制卵巢颗粒细胞活力和促进细胞凋亡(均P0.05)。结果表明:多囊卵巢综合征能促使高密度脂蛋白发生部分氧化修饰,氧化修饰高密度脂蛋白能通过激活活性氧-p38信号通路促使大鼠卵巢颗粒细胞凋亡。

为探究3种卤乙酰胺对萼花臂尾轮虫(Brachionus calyciflorus)存活、种群增长、有性生殖和氧化应激效应的影响,以淡水常见萼花臂尾轮虫为受试生物,开展了不同浓度氯乙酰胺、二氯乙酰胺和溴乙酰胺对轮虫24 h急性致死、2 d种群增长、4 d有性生殖、7 d休眠卵产量以及氧化应激指标影响的研究.结果表明:①3种卤乙酰胺对萼花臂尾轮虫急性毒性呈溴乙酰胺˃氯乙酰胺˃二氯乙酰胺的特征.②20、200μg/L氯乙酰胺和200μg/L溴乙酰胺均显著降低了萼花臂尾轮虫2 d种群增长率.③200μg/L氯乙酰胺提高了轮虫携卵与不携卵雌体数比值和混交率,20μg/L二氯乙酰胺降低了轮虫携卵与不携卵雌体数比值;同时,200μg/L二氯乙酰胺提高了轮虫受精率,20μg/L溴乙酰胺提高了轮虫携卵与不携卵雌体数比值、混交率和受精率.④10、20和200μg/L氯乙酰胺,20和200μg/L二氯乙酰胺以及10、20μg/L溴乙酰胺均显著增加了轮虫7 d休眠卵产量.⑤除200μg/L氯乙酰胺、二氯乙酰胺和溴乙酰胺中过氧化物酶活性下降外,其他浓度处理组中轮虫氧化应激指标值均普遍上升.研究显示,氯乙酰胺、二氯乙酰胺和溴乙酰胺均对萼花臂尾轮虫具有较高的致死毒性,能显著影响轮虫种群增长、有性生殖和氧化应激,并可能影响轮虫种群结构和规模,面临生态风险,7 d休眠卵产量是评价氯乙酰胺、二氯乙酰胺和溴乙酰胺对萼花臂尾轮虫有性生殖影响的合适指标.
