| 目的：研究丹皮酚(Paeonol，Pae)对TNF-alpha诱导的人牙龈成纤维细胞(human gingival fibroblasts，HGF)黏附分子表达水平的影响。方法：使用50 ng/mL 的肿瘤坏死因子(tumor necrosis factor，TNF)-alpha诱导刺激人牙龈成纤维细胞，后分别加入浓度为0、50、100、200 mmol/L的Pae 孵育培养2、4、6 天后，用Western blot 法检测细胞间黏附分子(intercellular adhesion molecule，ICAM)-1 以及血管细胞黏附分子(vascularcell adhesion molecule，VCAM)-1的蛋白表达水平，用逆转录多聚酶链反应(reverse transcription polymerase chain reaction，RT-PCR)检测黏附分子的mRNA 表达水平。结果：TNF-alpha诱导的人牙龈成纤维细胞ICAM-1 和VCAM-1 的蛋白和mRNA 表达水平均显著高于空白对照组(P<0.05)；不同浓度的丹皮酚可显著降低TNF-alpha诱导的人牙龈成纤维细胞ICAM-1 和VCAM-1 的蛋白和mRNA表达(P<0.05)，且随Pae 浓度的升高逐渐减少。当Pae 浓度达到100 mmol/L，蛋白和mRNA表达水平的抑制效果达到稳定程度（P>0.05），当Pae 浓度达到200 mmol/L 时，ICAM-1 和VCAM-1 mRNA 抑制效果达到诱导前的水平（P>0.05）。诱导时间的长短对蛋白和mRNA 表达水平抑制效果没有显著影响（P>0.05）。结论：丹皮酚可显著降低TNF-alpha诱导的人牙龈成纤维细胞黏附分子表达水平。 |
| 英文摘要: |
| Objective:To investigate the influence of Paeonol on human gingival fibroblasts (HGF) stimulated by adhesion
molecules.Methods:HGF were stimulated by 50 ng/mL tumor necrosis factor (TNF)-alpha, then different concentrations (0, 50, 100, 200
mmol/L) of Pae were added to the experimental group. The protein and mRNA expression of intercellular adhesion molecule (ICAM)-1
and vascular cell adhesion molecule (VCAM)-1 were examined by western blot and reverse transcription polymerase chain reaction
(RT-PCR).Results:The protein and mRNA expression of ICAM-1 and VCAM-1 were increased by TNF-alpha stimulation (P<0.05), while
Pae inhibited the expression of ICAM-1 and VCAM-1 with the increase of Pae concentration (P<0.05). There was no significant effect of
inhibition on the expression of the protein and mRNA levels in induction time (P>0.05).Conclusion:Paeonol had the potential to provide
new method for the treatment of periodontal disease. |
