摘要:


文题释义:

蒙药额尔敦-乌日勒:可有效降低碘乙酸钠诱导的大鼠骨关节炎骨与软骨代谢指标和炎性指标,而这一变化与蒙药额尔敦-乌日勒用药剂量与用药时间长短有关联,剂量越大、用药时间越长,上述变化越明显。
骨关节炎:是一种关节软骨被侵蚀、骨质增生、软骨下骨硬化以及滑膜和关节腔的一系列病理生理改变而引起的骨关节退行性病变。


背景:传统蒙医临床应用蒙药额尔敦-乌日勒治疗骨关节炎的疗效肯定,但其治疗作用及相关机制尚不明确。

目的:观察蒙药额尔敦-乌日勒对大鼠骨关节炎的修复过程,分析其作用机制。
方法:将30只8周龄SD大鼠,采用单侧膝关节腔内注射碘乙酸钠溶液建立骨关节炎模型。造模 2周后,采用随机数字表法将大鼠分为3组:对照组(6只)灌胃给予生理盐水,低、高剂量组(各12只)分别灌胃给予蒙药额尔敦-乌日勒1.4,2 g,3次/d。连续给药2,4周后,取大鼠血液样本、关节软骨及关节周围骨质,检测软骨代谢标志物(软骨寡聚基质蛋白、蛋白聚糖)、骨代谢标志物(骨碱性磷酸酶、硫酸盐角蛋白)、炎性标志物(白细胞介素6、肿瘤坏死因子α)、脂代谢标志物(总胆固醇、三酰甘油)等相关因子的变化,同时进行病理组织学观察。

结果与结论:①给药2,4周后的qRT-PCR检测结果显示,与对照组比较,低、高剂量组大鼠膝关节软骨组织中寡聚基质蛋白、蛋白聚糖及关节周围骨质中骨碱性磷酸酶、硫酸盐角蛋白的mRNA表达均显著降低(P < 0.05,P < 0.01,P < 0.001),其中以高剂量组降低更显著;②给药2,4周后,与对照组比较,低、高剂量组大鼠血清肿瘤坏死因子α、白细胞介素6水平降低(P < 0.01,P < 0.001),总胆固醇、三酰甘油水平升高(P < 0.05,P < 0.01,P < 0.001),其中以高剂量组改善更显著;③苏木精-伊红染色显示,对照组大鼠膝关节软骨组织表层有较大缺损区,组织结构不明,炎症细胞浸润严重;低剂量组给药2周后大鼠膝关节软骨表面粗糙,细胞排列紊乱,软骨结构改善不明显,给药4 周后大鼠膝关节软骨炎性细胞减少,结构有所恢复;高剂量组给药2周后大鼠膝关节软骨组织结构较清晰,炎症明显减轻,给药4周后大鼠膝关节软骨组织结构更清晰;④结果表明,蒙药额尔敦-乌日勒有较好的抗炎及改善软骨代谢等功效,对大鼠骨关节炎有明显的改善作用。

Abstract: BACKGROUND: The clinical application of Mongolian Medicine Erdun -uril in the treatment of osteoarthritis is effective, but its therapeutic effect and related mechanism are still unclear. 
OBJECTIVE: To observe the repairing process of osteoarthritis in rats by Mongolian Medicine Erdun-uril and analyze its mechanism.
Methods: Thirty male Sprague-Dawley rats (8 weeks of age) were selected to establsih an osteoarthritis model using intraarticular injection of sodium iodoacetate solution into the unilateral knee joint. Two weeks after modeling, the model rats were randomly divided into three groups: control group (n=6) was given normal saline by gavage, and low and high dose groups (n=12 per group) were given Erdun-uril 1.4 and 2 g, respectively, 3 times per day. After 2 and 4 weeks of continuous administration, blood samples, articular cartilage and periarticular bone tissue were taken from rats to detect changes in cartilage metabolic markers (cartilage oligomeric matrix protein, proteoglycan), bone metabolic markers (bone alkaline phosphatase, keratan sulfate), inflammatory markers (interleukin 6, tumor necrosis factor α), lipid metabolic markers (total cholesterol, triacylglycerol). Histopathological changes were also observed.
ResultS and CONCLUSION: qRT-PCR results showed that after 2 and 4 weeks of administration, the mRNA expression of cartilage oligomeric matrix protein, proteoglycan and bone alkaline phosphatase and keratan sulfate in knee cartilage of rats were significantly reduced in the low and high dose groups compared with the control group (P < 0.05, P < 0.01, P < 0.001), with the reduction being more significant in the high dose group. After 2 and 4 weeks of administration, compared with the control group, serum tumor necrosis factor α and interleukin 6 levels were decreased (P < 0.01, P < 0.001) and total cholesterol and triacylglycerol levels were increased (P < 0.05, P < 0.01, P < 0.001) in the low and high dose groups, with the improvement being more significant in the high dose group. Hematoxylin-eosin staining results showed that in the control group, there were large defective areas on the surface of the knee cartilage with unknown structure and severe inflammatory cell infiltration; in the low dose group, the surface of the knee cartilage was rough with disordered cell arrangement and the cartilage structure did not improve significantly after 2 weeks of administration, while the number of inflammatory cells in the knee cartilage was reduced and the cartilage structure was restored to some extent after 4 weeks of administration; in the high dose group, the structure of the knee cartilage become clear after 2 weeks of administration and even clearer after 4 weeks of administration, and the inflammation was significantly reduced after 2 weeks of administration. To conclude, Mongolian Medicine Erdun-uril with better anti-inflammatory properties can improve cartilage metabolism and obviously alleviate osteoarthritis in rats.
