摘要:


文题释义:

地黄梓醇是从地黄中提取出来的一种环烯醚萜苷化合物,2015 版《中国药典》明确规定了地黄梓醇可作为地黄质量控制的指标。地黄梓醇的药理作用包括抗细胞凋亡、抗炎等。

半乳糖凝集素3具有争议的促炎或抗炎活性,取决于各种因素,包括其细胞内或细胞外定位以及与这些过程有关的靶细胞。一方面半乳糖凝集素3通过清除凋亡的中性粒细胞可能有助于消除炎症;另一方面,半乳糖凝集素3通过加强巨噬细胞、肥大细胞和自然杀伤细胞以及TB淋巴细胞的活化而显示出大部分促炎作用。

背景:在膝骨关节炎早期,滑膜分泌炎症递质可能是诱导膝骨关节炎发病的重要因素之一,伴随着膝骨关节炎的进一步加重。

目的观察不同浓度地黄梓醇对早期膝骨性关节炎大鼠膝关节滑膜组织中白细胞介素、半乳糖凝集素3、钙结合蛋白S100A12表达水平的影响,探讨地黄梓醇治疗早期膝骨性关节炎的作用机制。

方法48只成年雄性Wistar大鼠中随机抽取14只为正常对照组,其余34只为模型组,实验开始后第147天于右膝关节腔注射4%木瓜蛋白酶联合0.03 mol/L半胱氨酸溶液0.2 mL制备早期膝骨关节炎模型。实验开始后第10天随机抽取正常对照组大鼠4只,造模组大鼠4只,采用苏木精-伊红染色及MankinOARSI评分进行模型验证,将模型组剩余30只大鼠采用随机数字法分为模型对照组、地黄梓醇低剂量组、地黄梓醇高剂量组,每组10只。验证造模成功后第2天,地黄梓醇低剂量组、地黄梓醇高剂量组灌胃0.2 mL/kg相应浓度的地黄梓醇,正常对照组、模型对照组灌胃等量生理盐水,均为1/d,连续灌胃28 d。取各组大鼠右膝关节滑膜组织,采用ELISA法检测各组大鼠滑膜组织中白细胞介素、半乳糖凝集素3、钙结合蛋白S100A12水平。

结果与结论模型组Mankin评分和OARSI分均显著高于正常对照组,差异有显著性意义(P < 0.05)与正常对照组比较,模型对照组滑膜组织中S100A12、白细胞介素、半乳糖凝集素3水平显著升高(P < 0.01);与模型对照组比较,地黄梓醇低剂量组滑膜组织中S100A12、白细胞介素、半乳糖凝集素3水平有所降低(P < 0.05),地黄梓醇高剂量组降低更明显(P < 0.01)结果表明,地黄梓醇可通过降低滑膜组织中相关炎症因子水平来减轻炎症反应从而减缓膝骨关节炎进展。

Abstract:

BACKGROUND: Inflammatory transmitters secreted from the synovium may be one of the important factors inducing the onset of knee osteoarthritis, and further exacerbate knee osteoarthritis.

OBJECTIVE: To observe the effect of different concentrations of catalpol from the root of Rehmannia glutinosa on the expression of interleukin-1β, galectin 3 and S100A12 in the synovium of the knee joint in rats with early knee osteoarthritis, and to explore the mechanism of catalpol from the root of Rehmannia glutinosa in the treatment of early knee osteoarthritis.

METHODS: The 14 of 48 adult male Wistar rats were randomly selected as a normal control group, and the remaining 34 rats were injected with 4% papain and 0.03 mol/L cysteine solution (0.2 mL) into the right knee joint cavity at 1, 4, 7 days after the initialization of the experiment to duplicate the model of early knee osteoarthritis. At 10 days after the initialization of the experiment, 4 rats in each group were randomly selected for histological observation using hematoxylin-eosin staining and validation of the model using Mankin and OARSI grading evaluation. After the model was successfully verified, the remaining 30 rats in the model group were randomly divided into model control group, low-dose group and high-dose group. At 2 days after successful modeling, each treatment group was infused with corresponding drugs at a dose of  0.2 mL/kg, and normal control group and model control group were infused with normal saline, once a day for 28 consecutive days. The synovium of the right knee joint was then taken from rats in each group, and the expression of interleukin-1β, galectin 3 and S100A12 in the rat synovium was detected by ELISA.

RESULTS AND CONCLUSION: Mankin score and OARSI grading were significantly higher in the model control group than the normal control group (P < 0.05). The levels of S100A12, interleukin-1β and galectin 3 in the synovium were significantly higher in the model control group than the normal control group (P < 0.01). Compared with the model control group, the levels of S100A12, interleukin-1β and galectin 3 in the synovium was decreased somewhat in the low-dose group (P < 0.05), but significantly decreased in the high-dose group (P < 0.01). Therefore, catalpol from the root of Rehmannia glutinosa can delay the progression of knee osteoarthritis by reducing the level of inflammatory factors in the synovium.
