摘要:

文题释义:
基质金属蛋白酶13(MMP13):是调控软骨降解的主要蛋白酶,与其他基质金属蛋白酶相比,基质金属蛋白酶13的表达更局限于结缔组织,它不仅抑制软骨细胞Ⅱ型胶原的表达,而且还是调控降解软骨细胞蛋白聚糖的关键酶,另外对Ⅳ型和Ⅸ型胶原蛋白以及骨连接蛋白都有抑制作用。临床研究表明,关节软骨受损患者的基质金属蛋白酶13表达量升高,提示基质金属蛋白酶13可能参与骨关节炎病理改变。
黄腐酚:黄腐酚是啤酒花中干质量最丰富的异戊二烯类黄酮,占啤酒花干质量的0.1%-1%,表现出广泛的有益药理特性,包括抗癌、抗病毒、抗真菌和抗血浆活性。近来越来越多的证据表明黄腐酚对炎症反应也具有调控作用,这些结果促使研究者进一步开展黄腐酚对骨关节炎作用的研究。


背景:研究表明黄腐酚具有抗氧化和抗炎作用,但目前尚无关于黄腐酚对骨关节炎具体作用的研究。
目的:从体外和体内两方面探讨黄腐酚对骨关节炎的作用及其潜在机制。
方法:①通过白细胞介素1β处理构建小鼠软骨细胞关节炎模型,然后用0-40 µmol/L黄腐酚干预,利用Elisa法检测软骨细胞炎性因子水平,RT-PCR检测软骨细胞合成及代谢指标;②通过小鼠内侧半月板失稳术构建小鼠关节炎模型,给予50 mg/(kg•d)黄腐酚干预6周,组织学染色评估关节软骨受损程度,μCT扫描分析膝关节软骨下骨的骨量变化。
结果与结论:①黄腐酚处理抑制了白细胞介素1β诱导的软骨细胞炎症相关细胞因子如一氧化氮、前列腺素E2、肿瘤坏死因子α和白细胞介素6的生成;②黄腐酚通过下调基质金属蛋白酶13的mRNA表达量并增加Ⅱ型胶原mRNA合成来抑制白细胞介素1β诱导的软骨细胞外基质降解;③接受黄腐酚处理的小鼠能明显延缓手术诱导的骨关节炎进展,拥有更加良好的关节软骨形态和更理想的骨关节炎病理评分,同时也能更好地维持软骨下骨的骨量。结果表明:黄腐酚能抑制软骨细胞的炎性递质生成,抑制软骨细胞外基质降解从而维持关节软骨的代谢平衡。

Abstract: BACKGROUND: Studies have shown that xanthohumol has antioxidant and anti-inflammatory properties; however, there is no study regarding the precise effect of xanthohumol on osteoarthritis. 
OBJECTIVE: To investigate the role of xanthohumol in the occurrence and development of osteoarthritis in vivo and in vitro.
METHODS: (1) A mouse osteoarthritis model was constructed by interleukin 1β treatment, followed by intervention with 0-40 µmol/L xanthohumol. The level of chondrocyte inflammatory factors was detected by ELISA, and the chondrocyte synthesis and metabolism indicators were detected by RT-PCR. (2) Surgery for medial meniscus instability was used to construct the arthritis model in mice, followed by intervention with 50 mg/kg/d xanthohumol for 6 weeks. Histological staining was used to evaluate the severity of damage to the articular cartilage, and μCT scan was used to analyze the changes in subchondral bone mass in the knee joint.
RESULTS AND CONCLUSION: The cytokines, such as nitric oxide, prostaglandin E2, tumor necrosis factor α and interleukin 6,  which were produced in response to interleukin 1β-induced chondrocyte inflammation, were inhibited by xanthohumol pretreatment. Xanthohumol prevented the degradation of the extracellular chondrocyte matrix caused by interleukin 1β by down-regulating metalloproteinase 13 matrix and by increasing the synthesis of type II collagen. Mice treated with xanthohumol dramatically postponed the development of osteoarthritis caused by surgery, and had better articular cartilage morphology and maintained subchondral bone density. Overall, these findings indicate that xanthohumol can inhibit the synthesis of chondrocyte inflammatory mediators, inhibit the degradation of the extracellular matrix of the cartilage, and maintain the metabolic equilibrium in the articular cartilage.
