摘要:

目的研究氧化苦参碱对内毒素(LPS)作用下人牙周膜细胞(PDLC)白细胞介素-6(IL-6)和白细胞介素-1β(IL-1β)mRNA表达的影响,探讨氧化苦参碱抑制LPS所造成的牙周炎症反应的机制。方法体外分离及培养PDLC,实验组分别为LPS和不同质量浓度的氧化苦参碱溶液的不同组合,对照组为仅含1% FBS的DMEM培养液。采用逆转录聚合酶链反应(RT-PCR)检测IL-6和IL-1β mRNA的水平。结果质量浓度为25 μg·mL-1 LPS能够有效地增强IL-6和IL-1β mRNA水平的表达,实验组高于对照组,差异有统计学意义,加入氧化苦参碱进行干预后实验组与对照组IL-6和IL-1β mRNA的表达无显著差异。结论氧化苦参碱可抑制LPS所造成的PDLC IL-6和IL-1β mRNA表达。

Abstract:

Objective To observe the effects of oxymatrine on the expression of interleukin-6(IL-6), interleukin- 1β(IL-1β)mRNA of human periodontal ligament cell(PDLC) stimulated by lipopolysaccharides(LPS), and to discuss oxymatrine’s inhibition mechanism on periodontal inflammation stimulated by LPS. Methods Firstly, isolate PDLC externally and culture them; for oxymatrine experimental group we used different combination of LPS and oxymatrine in different concentration, and for the matched group we use DEME nutrient solutions of 1% FBS. Then reverse transcription -polymerase chain reaction(RT -PCR) for checking the level of IL -6 and IL -1β mRNA. Results 25 μg·mL-1 LPS can significantly enhance the expression of both IL-6 and IL-1β mRNA’s level, and oxymatrine could restrain above phenomena. Conclusion Oxymatrine can restrain the expression of IL-6 and IL-1β mRNA of human PDLC stimulated by LPS.
