摘要:

文题释义:
痛风性关节炎:是由于尿酸盐沉积在关节囊、滑囊、软骨、骨质和其他组织中而引起病损及炎性反应,多见于第一跖趾关节,也可发生于其他较大关节,尤其是踝部与足部关节。
白细胞介素17:是一种主要由活化的T 细胞产生的致炎细胞因子,可以促进T 细胞的激活和刺激上皮细胞、内皮细胞、成纤维细胞产生多种细胞因子如白细胞介素6、白细胞介素8、粒细胞-巨噬细胞刺激因子和化学增活素及细胞黏附分子1,从而导致炎症的产生。

背景:研究发现,阻断滑膜分泌炎症递质的药物治疗急性痛风性关节炎有较好的应用前景。近年来,中药治疗急性痛风性关节炎的研究取得了很大成就。
目的:探讨黑骨藤醇提取物对急性痛风性关节炎血清炎性因子及滑膜功能的影响。
方法:将60只健康SD大鼠随机分为6组,分别为空白对照组、模型对照组、秋水仙碱治疗组、黑骨藤醇提取物高、中、低剂量治疗组,每组10只。除空白对照组外,其他各组均在关节腔内注入尿酸钠溶液制备急性痛风性关节炎模型,然后予以秋水仙碱、高、中、低剂量黑骨藤醇提取物治疗。造模后1-7 d观察关节肿胀度;造模后7 d采用ELISA检测血清和滑膜组织中白细胞介素1β、肿瘤坏死因子α、白细胞介素17水平,苏木精-伊红染色观察滑膜病理改变,Western blot检测滑膜组织中NF-κB、ERK1/2和JNK蛋白表达。
结果与结论:①模型对照组大鼠关节肿胀,血清和滑膜组织中白细胞介素1β、肿瘤坏死因子α、白细胞介素17水平升高,滑膜组织具有明显炎性细胞浸润和滑膜细胞增生,NF-κB、ERK1/2和p-JNK蛋白表达水平明显升高;②给予秋水仙碱、黑骨藤醇提取物治疗后,上述指标明显改善,高剂量黑骨藤醇提取物组与秋水仙碱组无显著差异,且黑骨藤醇提取物具有剂量依赖性;③结果表明,黑骨藤醇提取物能明显改善急性痛风性关节炎大鼠关节症状,下调炎症因子表达水平,改善滑膜功能,该作用可能与其下调NF-κB、ERK1/2和p-JNK蛋白表达有关。

Abstract: BACKGROUND: Studies have found that drugs that block the secretion of inflammatory transmitters in the synovium have good application prospects in the treatment of acute gouty arthritis. In recent years, great achievements have been made in the treatment of acute gouty arthritis with traditional Chinese medicine.
OBJECTIVE: To study the effect of alcohol extract of Gardneria angustifolia on serum inflammatory factors and synovial cell function in patients with acute gouty arthritis.
METHODS: Sixty healthy Sprague-Dawley rats were randomly divided into six groups: blank control group, model control group, colchicine treatment group, Gardneria angustifolia alcohol extract high, medium and low dose treatment groups, withy 10 rats in each group. In addition to the blank control group, the other groups were injected with sodium urate solution into the articular cavity to prepare acute gouty arthritis models, and then treated with colchicine, high, medium and low doses of Gardneria angustifolia alcohol extract. The swelling degree of the joint was observed at 1-7 days after modeling. At 7 days after modeling, the levels of interleukin-1β, tumor necrosis factor-α, interleukin-17 in the serum and synovium were detected by ELISA; the pathological changes of the synovium were observed by hematoxylin-eosin staining, and the expression of nuclear factor- κB, ERK1/2 and JNK protein in the synovium was detected by western blot.
RESULTS AND CONCLUSION: In the model control group, the joint swelling, the level of interleukin-1β, tumor necrosis factor-α, and interleukin-17 in the serum and synovium were increased, the synovium had obvious inflammatory cell infiltration and synovium cell proliferation, the expression of nuclear factor-κB, ERK1/2 and p-JNK protein was significantly increased. After the treatment with colchicine and Gardneria angustifolia alcohol extracts, the above indexes were significantly improved, and there was no significant difference in the high dose Gardneria angustifolia alcohol extract group and colchicine group. Moreover, Gardneria angustifolia alcohol extracts showed a dose-dependent effect. The alcohol extract of Gardneria angustifolia can significantly improve the symptoms of acute gouty arthritis in rats, down-regulate the expression of inflammatory factors, and improve the function of synovial cells, which may be related to the down-regulation of nuclear factor-κB, ERK1/2 and p-JNK protein expression.
