摘要:


文题释义:
骨关节炎:是一种以关节软骨损害为主,并累及整个关节组织最常见的关节疾病,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,表现为关节疼痛、僵硬、肥大及活动受限。  
人工虎骨粉:是一种天然虎骨的仿生中成药,其有效成分和药理作用与天然虎骨一致,具有抗炎、镇痛、增强机体免疫力、促进骨折愈合等功效,适用于关节炎、风湿、骨质疏松等疾病。

背景:脊柱骨关节炎是以脊柱小关节、关节韧带和肌腱为主要表现的慢性炎症性疾病,是慢性腰痛的主要原因。人工虎骨粉具有抗炎和缓解疼痛的生物作用,因此有望为脊柱骨关节炎治疗提供新的策略。
目的:探讨人工虎骨粉调控白细胞介素23/白细胞介素17(IL-23/IL-17)免疫轴炎症因子表达水平改善大鼠脊柱骨关节炎的分子作用机制。 
方法:60只大鼠随机分为空白对照组、模型组及人工虎骨粉低、中、高剂量组,每组12只。除空白对照组外,其余各组通过对大鼠腰椎关节囊关节腔内注射碘乙酸0.1 mL建立骨关节炎模型。造模15 d后人工虎骨粉低、中、高剂量组分别按120,240,480 mg/(kg•d)灌胃给药治疗,空白对照组、模型组给予等体积生理盐水灌胃。给药21 d后,采用Western Blot法测量大鼠脊柱关节软骨中白细胞介素17、白细胞介素23、基质金属蛋白酶3、趋化因子受体6的表达水平;ELISA法检测大鼠血清中相关炎症因子的表达水平;应用苏木精-伊红染色和番红 O-固绿染色法观察大鼠关节损伤退变程度。
结果与结论:①Western Blot检测结果显示,人工虎骨粉高剂量组大鼠的关节软骨中白细胞介素17、白细胞介素23、基质金属蛋白酶3、趋化因子受体6的表达水平较模型组显著降低(P < 0.05);②ELISA检测结果显示,与模型组相比,人工虎骨粉中、高剂量组大鼠的血清白细胞介素17、肿瘤坏死因子α、白细胞介素1β、基质金属蛋白酶3水平下调效果显著(P < 0.05); ③苏木精-伊红染色和番红 O-固绿染色显示,人工虎骨粉各剂量组大鼠滑膜炎症细胞浸润及增生情况较模型组明显改善,其中人工虎骨粉中、高剂量组病理炎症国际骨关节炎研究学会评分及Mankin’s 评分显著降低(P < 0.05);④提示人工虎骨粉可明显改善碘乙酸化学刺激引起的大鼠脊柱小关节的炎症及退变,其中高剂量组效果更显著,其机制可能是通过抑制IL-23/IL-17免疫轴相关炎症因子的表达,改善关节软骨免疫微环境。

Abstract: BACKGROUND: Spine osteoarthritis is a chronic inflammatory disease of the spine, articular ligaments, and tendons, and is the main cause of chronic low back pain. Artificial tiger bone powder has anti-inflammatory and pain-relieving biological effects, so it is expected to provide a new strategy for targeted therapy of spinal osteoarthritis.
OBJECTIVE: To investigate the mechanism of artificial tiger bone meal in regulating the expression level of interleukin-23/interleukin-17 immune axis in improving spine osteoarthritis in rats.
METHODS: Sixty SD rats were randomly divided into blank control group, model group, artificial tiger bone meal low-, medium- and high-dose groups, with 12 rats in each group. Except for the blank control group, osteoarthritis models were established in the other groups by injecting 0.1 mL of iodoacetic acid into the joint cavity of the lumbar vertebral joint capsule of the rats. 15 days after modeling, the artificial tiger bone meal low, medium and high dose groups were treated by intragastric administration of 120, 240 and 480 mg/kg per day respectively. The blank control group and model group were given the same volume of normal saline by gavage. After 21 days of treatment, the expression levels of interleukin-17, interleukin-23, matrix metalloproteinase-3, and chemokine receptor-6 in rat spinal articular cartilage were measured by western blot assay. The expression levels of related inflammatory factors in rat serum were detected by ELISA. The degree of joint injury and degeneration in rats was observed by hematoxylin-eosin staining and safranin O-fast green staining.  
RESULTS AND CONCLUSION: (1) The results of western blot assay showed that the expression levels of interleukin 17, interleukin 23, matrix metalloproteinase 3, and chemokine receptor 6 in the articular cartilage of rats in the artificial tiger bone meal high-dose group were significantly lower than those in the model group (P < 0.05). (2) ELISA results showed that compared with the model group, the artificial tiger bone meal medium- and high-dose groups had a significant down-regulating effect on the levels of serum interleukin 17, tumor necrosis factor α, interleukin 1β, and matrix metalloproteinase 3 (P < 0.05). (3) Hematoxylin-eosin staining and saffron O-solid green staining showed that the infiltration and proliferation of synovial inflammatory cells in each treatment group of artificial tiger bone meal were significantly improved compared with the model group, and the pathological inflammation Osteoarthritis Research Society International score and Mankin’s score in the medium- and high-dose groups of artificial tiger bone meal were significantly reduced (P < 0.05). (4) It is suggested that artificial tiger bone meal could significantly improve the inflammation and degeneration of spinal facet joints caused by iodoacetic acid chemical stimulation. Among them, the effect of the high-dose group was more significant. The mechanism may be to inhibit the expression of interleukin-23/interleukin-17 immune axis-related inflammatory factors and improve the immune microenvironment of articular cartilage.
