摘要:


文题释义:

淫羊藿苷:是从小檗属淫羊藿中提取的天然类黄酮化合物,具有许多生物活性和药理作用,可能通过促进骨形成和抑制炎症在炎症性骨破坏疾病中发挥重要作用。此外淫羊藿苷还具有抗氧化、抗衰老和抗肿瘤作用。
脂多糖:是牙髓卟啉单胞菌外膜的主要成分,可直接或间接抑制成骨细胞功能和刺激破骨细胞形成来影响骨结构。


背景:研究表明慢性根尖周炎是常见的炎症性骨破坏疾病之一,淫羊藿苷可以促进成骨分化、抑制骨吸收,可能对慢性根尖周炎引起的骨破坏起到保护作用。

目的:探讨在脂多糖刺激的炎症环境下淫羊藿苷对MC3T3-E1细胞增殖分化的影响。
方法:应用脂多糖刺激MC3T3-E1细胞建立体外炎症环境,采用CCK-8检测脂多糖最佳作用质量浓度及作用时间;CCK-8检测在1 μg/mL脂多糖刺激下淫羊藿苷的最佳作用质量浓度;碱性磷酸酶染色、Real-time PCR及Western blot检测炎症环境下淫羊藿苷对MC3T3-E1细胞成骨分化的影响;Real-time PCR及Western blot检测炎症环境下淫羊藿苷对MC3T3-E1细胞炎症相关因子白细胞介素1β、白细胞介素6表达的影响。

结果与结论:①CCK-8结果显示,淫羊藿苷的最佳作用质量浓度为0.1 μg/mL;②在炎症环境下,淫羊藿苷增强了碱性磷酸酶的表达,促进了成骨细胞分化;③与脂多糖组相比,脂多糖+淫羊藿苷组成骨相关因子碱性磷酸酶、Runx2表达升高;④与脂多糖组相比,脂多糖+淫羊藿苷组炎症相关因子白细胞介素1β、白细胞介素6表达水平下降;⑤结果提示,脂多糖能导致MC3T3-E1细胞成骨分化能力减弱并加重炎症反应,淫羊藿苷对其具有保护作用。

Abstract: BACKGROUND: Studies have shown that chronic apical periodontitis is one of the common inflammatory bone destruction diseases. Icariin can promote osteogenic differentiation, inhibit bone resorption, and may play a protective role in bone destruction caused by chronic apical periodontitis.
OBJECTIVE: To investigate the effect of icariin on the proliferation and differentiation of MC3T3-E1 cells in the inflammatory environment stimulated by lipopolysaccharides.
METHODS: Lipopolysaccharides were used to stimulate MC3T3-E1 cells to establish an inflammatory environment in vitro, and cell counting kit-8 was used to detect the best concentration and optimal action time of lipopolysaccharides. Cell counting kit-8 was used to detect the optimal concentration of icariin under the stimulation of lipopolysaccharides at a concentration of 1 μg/mL. Alkaline phosphatase detection, Real-time PCR and western blot assay were used to detect the effect of icariin on osteogenic differentiation of MC3T3-E1 cells in the inflammatory environment. Real-time PCR and western blot were used to detect the effects of icariin on the expression of interleukin-1β and interleukin-6 in MC3T3-E1 cells in the lipopolysaccharide-stimulated inflammatory environment.
RESULTS AND CONCLUSION: Cell counting kit-8 results showed that the optimal concentration of icariin was 0.1 μg/mL. In the inflammatory environment, icariin enhanced the expression of alkaline phosphatase and promoted osteoblast differentiation. Compared with the lipopolysaccharide group, the expression of osteogenesis-related factors alkaline phosphatase and Runx2 was increased in the lipopolysaccharide+icariin group. Compared with the lipopolysaccharide group, the expression levels of inflammation-related factors interleukin-1β and interleukin-6 decreased in the lipopolysaccharide+icariin group. To conclude, lipopolysaccharides weaken the osteogenic ability of MC3T3-E1 cells and aggravate the inflammatory response, but icariin has a protective effect on them.

Key words: MC3T3-E1 cell, icariin, chronic apical periodontitis, lipopolysaccharide, osteogenic differentiation
