摘要: 目的 采用人肾皮质近曲小管上皮细胞系HK-2细胞明确何首乌中主要蒽醌类成分大黄素、芦荟大黄素、大黄酸、大黄素甲醚和大黄酚与肾毒性的相关性。方法 HK-2细胞经2.5、10、20、40、80、120、160 μmol·L-1的大黄素、芦荟大黄素、大黄酸和3.125、12.5、25、50、100、150、200 μmol·L-1的大黄素甲醚和大黄酚作用 24、48 h后,采用细胞计数试剂盒法(CCK-8)测定这些单体对HK-2细胞存活率的影响。HK-2细胞经6.25、12.5、25、50、100 μmol·L-1的大黄素、芦荟大黄素、大黄酸、大黄素甲醚和大黄酚作用 24、48 h后,收集细胞培养液检测乳酸脱氢酶(LDH)释放水平;采用酶联免疫吸附法(ELISA)检测肾损伤分子-1(Kim-1)蛋白表达水平;以JC-10荧光探针检测线粒体膜电位(MMP)的变化;并以流式检测法测定5种蒽醌类化合物对细胞凋亡率的影响。结果 大黄素、芦荟大黄素、大黄酸和大黄酚致 HK-2 细胞存活率随给药时间和给药浓度的增加而降低,与对照组相比差异具有统计学意义(P<0.05),而大黄素甲醚和大黄酚 200 μmol·L-1给药 48 h 后细胞存活率仍大于 75%。大黄素、芦荟大黄素和大黄素甲醚100 μmol·L-1给药48 h后,LDH释放水平相较于对照组显著升高(P<0.01)。5种何首乌蒽醌类单体成分对HK-2细胞给药后细胞上清中Kim-1水平未呈现出随浓度增加而升高的趋势,仅在100 μmol·L-1给药后,Kim-1水平较对照组显著上升(P<0.05)。5种何首乌蒽醌类单体成分给药后,HK-2细胞的线粒体膜电位均随处理浓度的增大和给药时间的延长而下降,但仅25、50、100 μmol·L-1的大黄素、芦荟大黄素和50、100 μmol·L-1的大黄酸给药48 h后检测到显著的细胞凋亡(P<0.05)。结论 大黄素、芦荟大黄素和大黄酸是导致何首乌肾毒性的潜在蒽醌类成分。何首乌中其他成分的肾毒性风险有待进一步研究,提高安全合理用药水平。

Abstract: Objective To determine the correlation between nephrotoxicity and five components of Polygonum multiflorum. Methods After HK-2 cells were treated with 2.5, 10, 20, 40, 80, 120, 160 μmol·L-1 emodin, aloe-emodin, rhein and 3.125, 12.5, 25, 50, 100, 150, 200 μmol·L-1 physcion and chrysophanol for 24 and 48 hours, the effects of these monomers on viability of HK-2 cells were determined with the cell counting kit. After HK-2 cells were treated with 6.25, 12.5, 25, 50 and 100 μmol·L-1 emodin, aloe-emodin, rhein, physcion and chrysophanol for 24 and 48 hours, the cell culture medium was collected to detect the release level of lactate dehydrogenase(LDH). The expression level of Kim-1 protein was detected via Elisa assay, the changes of the mitochondrial membrane potential (MMP) were detected by the JC-10 fluorescence probe, and the effects of the five anthraquinones components on apoptosis were measured by flow cytometry. Results The viability of HK-2 cells decreased with the increased concentration and administration time of emodin, aloe-emodin, rhein and chrysophanol significantly (P<0.05), but remained more than 75% after administration of 200 μmol·L-1 physcion and chrysophanol for 48 hours. 48 hours after administration of 100 μmol·L-1 emodin, aloe-emodin and physcion, the release level of LDH was significantly higher than in the control group (P<0.01). After administration of the five anthraquinone monomers in Polygonum multiflorum, the level of Kim-1 in the HK-2 cell supernatant didn't increase with the concentration, but increased significantly compared with the control group after 100 μmol·L-1 administration (P<0.05). The mitochondrial membrane potential of HK-2 cells decreased with the concentration of treatment and duration of administration after the administration of the five anthraquinone components in Polygonum multiflorum. Conclusion Emodin, aloe-emodin and rhein are considered the potential anthraquinone components that causes nephrotoxicity in Polygonum multiflorum, and the nephrotoxicity risk of other components in Polygonum multiflorum needs to be studied.
