| 目的 观察六味地黄丸含药血清对氧化应激状态下MC3T3-E1细胞增殖、活性氧及自噬水平的影响。方法 用过氧化氢（H2O2）模拟氧化应激状态后采用不同浓度的六味地黄丸含药血清干预MC3T3-E1细胞，CCK-8法检测细胞增殖情况；通过细胞活性氧（reactive oxygen species，ROS）检测细胞ROS水平；qRT-PCR检测自噬相关基因Beclin 1、LC3B mRNA表达情况；蛋白印迹法检测自噬相关蛋白Beclin 1、LC3B表达情况。结果 ①CCK-8结果显示，H2O2会抑制成骨细胞的增殖，当其浓度为0.10 mmol/L时具有相对较小程度的抑制增殖效果；六味地黄丸含药血清可以促进氧化应激状态下成骨细胞的增殖，且当体积浓度为20%时促进增殖的效果最好。②细胞活性氧检测结果显示，六味地黄丸含药血清组ROS水平降低（P＜0.05）。③qRT-PCR结果显示，六味地黄丸组Beclin 1、LC3B mRNA表达上调（P＜0.05），且该作用会被自噬抑制剂所抑制。④蛋白印迹法结果显示，六味地黄丸组Beclin 1蛋白表达上调（P＜0.05），蛋白LC3Ⅱ/Ⅰ比值增高（P＜0.05）。结论 六味地黄丸含药血清可以促进氧化应激状态下成骨细胞增殖、降低细胞ROS水平，其机制可能与诱导细胞自噬相关。 |

| Objective To observe the effects of Liuwei Dihuang pill-containing serum on the proliferation and reactive oxygen species and autophagy levels of MC3T3-E1 cells under oxidative stress. Methods: MC3T3-E1 cells were intervened with different concentrations of Liuwei Dihuang pill-containing serum after simulating oxidative stress with hydrogen peroxide (H2O2). Cell proliferation was detected with CCK-8 method. Cell ROS levels were detected with cell reactive oxygen species (ROS). mRNA expressions of autophagy-related genes Beclin 1 and LC3B were detected with qRT-PCR. The expressions of autophagy-related proteins Beclin 1 and LC3B were detected with Western blotting. Results (1) CCK-8 results showed that H2O2 inhibited the proliferation of osteoblasts, and it had a relatively small inhibitory effect when its concentration was 0.10 mmol/L. Liuwei Dihuang pill-containing serum promoted the proliferation of osteoblasts under oxidative stress, and the best effect was achieved when the volume concentration was 20%. (2) The results of cell ROS detection showed that the ROS level in Liuwei Dihuang pill-containing serum group decreased (P<0.05). (3) The results of qRT-PCR showed that Beclin 1 and LC3B mRNA expressions were up-regulated in the Liuwei Dihuang pill group (P<0.05), and the effect was inhibited by autophagy inhibitors. (4) Western blotting results showed that expression of Beclin 1 was up-regulated and LC3II/Ⅰ ratio was increased (P<0.05). Conclusion Liuwei Dihuang pill-containing serum promotes osteoblast proliferation and reduces cellular ROS levels under oxidative stress. The mechanism may be related to the induction of cellular autophagy. |
