| 摘要: |
| 目的 探究羊踯躅含药血清对肿瘤坏死因子-α（tumor necrosis factor-α, TNF-α）诱导的类风湿关节炎成纤维样滑膜细胞（rheumatoid arthritis fibroblast-like synoviocytes, RA-FLS）增殖和炎症因子分泌的影响和作用机制，为临床治疗RA提供理论及实验依据。方法 将细胞分为空白组、模型组、雷公藤多苷组、5%和10%空白血清组及5%和10%羊踯躅含药血清组。RA-FLS经TNF-α（10 ng/mL）处理24 h以构建RA细胞模型。CCK-8检测细胞增殖情况。采用ELISA检测炎症因子白细胞介素-1β（interleukin-1 beta, IL-1β）、白细胞介素-17A（interleukin-17A, IL-17A）、白细胞介素-6（interleukin-6, IL-6）、白细胞介素-2（interleukin-2, IL-2）和γ干扰素（interferon-γ, IFN-γ）的含量。Western blot检测蛋白激酶B（protein kinase B, AKT1）、磷酸化AKT1（phosphorylated AKT1, p-AKT1）、原癌基因c-JUN、p-c-JUN、p65、p-p65、表皮生长因子受体（epidermal growth factor receptor, EGFR）蛋白表达水平。结果 与未用羊踯躅含药血清处理的正常RA-FLS相比，用5%和10%羊踯躅含药血清处理的细胞增殖活性在48 h内没有明显的变化（P＞0.05），而用20%和30%羊踯躅含药血清处理的细胞增殖活性明显降低（P＜0.05）。与空白组相比，模型组的细胞增殖活性显著上升（P＜0.05）；与5%和10%空白血清组相比，5%和10%羊踯躅含药血清组的细胞增殖活性均显著降低（P＜0.05）。与空白组相比，模型组的IL-1β、IL-17A、IL-6、IL-2和IFN-γ水平均明显升高（P＜0.05）；与5%和10%空白血清组相比，5%和10%羊踯躅含药血清组的IL-1β、IL-17A、IL-6、IL-2和IFN-γ水平明显下降（P＜0.05）。与空白组相比，模型组的EGFR表达量以及AKT1、c-JUN和p65的磷酸化水平均明显升高（P＜0.05）；与5%和10%空白血清组相比，5%和10%羊踯躅含药血清组的EGFR表达量以及AKT1、c-JUN和p65的磷酸化水平显著降低（P＜0.05）。此外，10%羊踯躅含药血清的效果比5%羊踯躅含药血清更为显著（P＜0.05）。结论 羊踯躅含药血清能抑制TNF-α诱导的RA-FLS增殖及促炎因子的分泌，其机制可能与调控EGFR、核因子-κB（nuclear factor-κB, NF-κB）、AKT和c-Jun N末端激酶（c-Jun N-terminal kinase, JNK）通路有关。 |

| Abstract: |
| Objective To explore the effects and mechanism of action of medicated serum containing Rhododendron molle G. Don on the proliferation and inflammatory factors secretion of tumor necrosis factor-α (TNF-α)-induced rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS), so as to provide theoretical and experimental basis for clinical treatment of RA. Methods RA-FLS cells were divided into blank group, model group, tripterygium glycosides group, blank serum (5%, 10%) groups, and medicated serum (5%, 10%) groups. RA-FLS were treated with TNF-α (10 ng/mL) for 24 h to construct RA cell models. Cell Counting Kit-8 (CCK-8) was utilized to examine cell proliferation. Enzyme-linked immunosorbent assay (ELISA) was used to determine the content of inflammatory factors including interleukin-1 beta (IL-1β), interleukin-17A (IL-17A), interleukin-6 (IL-6), interleukin-2 (IL-2), and interferon-gamma (IFN-γ). Western blot was used to determine the protein expression levels of protein kinase B (AKT1), phosphorylated AKT1 (p-AKT1), c-JUN, p-c-JUN, p65, p-p65, and epidermal growth factor receptor (EGFR). Results Compared with the groups without medicated serum containing Rhododendron molle G. Don, there was no significant change in cell proliferation activity within 48 h in the 5% and 10% medicated serum containing Rhododendron molle G. Don groups (P＞0.05), but cell proliferation activity significantly reduced in the 20% and 30% medicated serum containing Rhododendron molle G. Don groups (P＜0.05). Compared with the blank group, cell proliferation activity in the model group was significantly higher (P＜0.05). Compared with the 5% and 10% blank serum groups, cell proliferation activity in the medicated serum groups containing different doses of Rhododendron molle G. Don was significantly lower (P＜0.05). Compared with the blank group, the levels of IL-1β, IL-17A, IL-6, IL-2, and IFN-γ in the model group were significantly higher (P＜0.05). Compared with the blank serum groups, the levels of IL-1β, IL-17A, IL-6, IL-2, and IFN-γ in the serum groups containing different doses of Rhododendron molle G. Don were significantly lower (P＜0.05). Compared with the 5% and 10% blank group, the expression level of EGFR as well as the phosphorylation levels of AKT1, c-JUN, and p65 in the model group were significantly higher (P＜0.05). Compared with the blank serum groups, the expression levels of EGFR as well as the phosphorylation levels of AKT1, c-JUN, and p65 in the medicated serum groups containing different doses of Rhododendron molle G. Don were significantly lower (P＜0.05). Additionally, the effects of the 10% serum containing Rhododendron molle G. Don were more significant than those of the 5% medicated serum containing Rhododendron molle G. Don (P＜0.05). Conclusion The medicated serum containing Rhododendron molle G. Don can inhibit cell proliferation and the secretion of pro-inflammatory factors of RA-FLS induced by TNF-α, which may be related to the regulation of EGFR, nuclear factor κB (NF-κB), AKT, and c-JUN N-terminal kinase (JNK) pathways. |
