摘要:

文题释义:
骨关节炎:又称为骨关节病,退行性关节病和骨质增生,是一种最常见的关节疾病。该病不仅发生关节软骨损害,还累及整个关节,包括软骨下骨、韧带、关节囊、滑膜和关节周围肌肉,最终发生关节软骨退变、纤维化、断裂、溃疡及整个关节面的损害。典型的临床表现包括疼痛、僵硬和关节变形。
蒙药蓝刺头:所含化学成分十分复杂,主要含有生物碱类、黄酮类、三萜类和有机酸及其酯类等,具有多种生物活性。始载于蒙医医典《智慧文鉴》中,具有“接骨愈伤、壮骨冶”的功能,属于蒙医自采自用药之一。

背景:骨关节炎临床上常见,是导致中老年人慢性残障的最常见原因。蒙药蓝刺头在骨病中有积极的治疗作用,然而其对骨关节炎的作用与机制尚待研究。
目的:探究蒙药蓝刺头在膝骨关节炎中的作用以及对Ⅱ型胶原蛋白和基质金属蛋白酶13表达的影响。
方法:选取健康中国大耳白兔30只,随机分组,正常对照组10只;膝骨关节炎组20只兔右膝关节用管型石膏固定8周,制备膝骨关节炎模型,造模成功后又分为蓝刺头治疗组及模型对照组(n=10)。蓝刺头治疗组兔灌胃20 mL/kg的蒙药蓝刺头溶液,含药量为3.25 g/L;正常对照组与模型对照组灌胃生理盐水20 mL/kg。各组均连续灌胃90 d,之后麻醉处死取膝关节软骨制备切片。苏木精-伊红染色观察软骨组织学变化;RT-PCR测定各组中Ⅱ型胶原蛋白、基质金属蛋白酶13 的mRNA表达,免疫组化法观察各组中Ⅱ型胶原蛋白、基质金属蛋白酶13的蛋白表达。
结果与结论:①通过苏木精-伊红染色观察发现,蒙药蓝刺头可以改善骨关节炎软骨损伤,促进软骨细胞及基质增生;②此外,蒙药蓝刺头可以促进骨关节炎中Ⅱ型胶原蛋白的mRNA及蛋白表达,抑制由骨关节炎引起的基质金属蛋白酶13 mRNA及蛋白高表达;③提示蒙药蓝刺头可以通过促进Ⅱ型胶原蛋白表达,抑制基质金属蛋白酶13表达,对骨关节炎起到积极的防治作用。
缩略语:基质金属蛋白酶13:matrix metalloproteinase 13,MMP-13

Abstract: BACKGROUND: Osteoarthritis is clinically common, which is the most common cause of chronic disability in middle-aged and elderly people. Echinops latifolius, as a Mongolian medicine, has positive therapeutic effect in bone diseases. However, its effect and mechanism on osteoarthritis remain to be investigated.
OBJECTIVE: To investigate the effect of Echinops latifoliuss on knee osteoarthritis and on the expression of type II collagen and matrix metalloproteinase 13.
METHODS: Thirty healthy Chinese white rabbits were selected and randomly divided into a control group (n=10) and a knee osteoarthritis group (n=20). Rabbits in the knee osteoarthritis group were fixed with cast plaster for 8 weeks to prepare knee osteoarthritis models. After successful modeling, rabbits in the knee osteoarthritis group were subdivided into an Echinops latifolius group and a model control group. In the Echinops latifolius group, 3.25 g/L Echinops latifolius was administered at a dose of 20 mL/kg by gavage. The control and model control groups were intragastrically administered normal saline at a dose of 20 mL/kg. Rabbits in each group were given continuous gastric gavage for 90 days, and then killed under anesthesia. Knee joint cartilage was taken and sliced. Hematoxylin-eosin staining was use to observe the histological changes of cartilage. RT-PCR was used to detect the mRNA expression of type II collagen and matrix metalloproteinase 13, and immunohistochemical staining was used to detect the protein expression of type II collagen and matrix metalloproteinase 13. 
RESULTS AND CONCLUSION: Echinops latifolius could improve osteoarthritis-induced cartilage damage of and promote the proliferation of chondrocytes and matrix. In addition, Echinops latifolius could promote the mRNA and protein expression of type II collagen in osteoarthritis, and inhibit the high expression of matrix metalloproteinase 13 at mRNA and protein levels caused by osteoarthritis. To conclude, Echinops latifolius can promote the expression of type II collagen and inhibit the expression of matrix metalloproteinase 13, thereby playing a positive role in the prevention and treatment of osteoarthritis.

Key words: osteoarthritis, Mongolian medicine, Echinops latifolius, type II collagen, matrix metalloproteinase 13, ethnic medicine
