文题释义:
关节软骨的营养:来源于滑液的渗透,关节软骨与关节滑液之间存在一定的物质交换。与血液和尿液相比,关节液成分及量的变化更能反映关节内组织病变的发生和发展。
miR-140-3p:其为pre-miR-140转录而来的单链小分子RNA,其不编码蛋白质,但可在转录后调控基因表达,影响蛋白质的翻译,参与机体各种重要的生理和病理过程。
 
摘要
背景:骨关节炎是一种与年龄相关,以关节软骨退变为特点的关节疾病。
目的:检测膝关节液中miR-140-3p的表达,明确其表达量是否与骨关节炎严重程度相关。
方法:共收集到健康志愿者、痛风性关节炎患者、类风湿性关节炎患者各10例,膝骨关节炎患者45例,其中骨关节炎早期、中期、晚期各15例。应用实时荧光定量PCR检测各组膝关节液中miR-140-3p的表达。
结果与结论:①骨关节炎组miR-140-3p的表达明显下调,非骨关节炎组与骨关节炎组间表达量差异有显著性意义(P < 0.05),健康对照组、痛风性关节炎与类风湿性关节炎组间差异无显著性意义(P > 0.05);②健康对照组miR-140-3p的表达量是骨关节炎组的11.4倍,随骨关节炎严重程度的增加miR-140-3p表达量呈相对减少的趋势;③进一步行Spearman等级相关分析显示:骨关节炎的严重程度与miR-140-3p的表达量均呈负相关;④结果表明,关节液中miR-140-3p的表达量可以在一定程度上反映骨关节炎病程的进展。

Abstract:

BACKGROUND: Osteoarthritis is an age-related joint disease characterized by articular cartilage degeneration.

OBJECTIVE: To assess the expression of miR-140-3p in synovial fluid of knee osteoarthritis, and identify whether miR-140-3p levels in synovial fluid are correlated with disease severity.
METHODS: We collected 10 healthy volunteers, 10 patients with gouty arthritis, 10 patients with rheumatoid arthritis, and 45 patients with knee osteoarthritis (15 cases in early stage, 15 cases in middle stage and 15 cases in the late stage). Real-time fluorescence quantitative PCR was used to detect miR-140-3p expression in synovial fluid in each group.
RESULTS AND CONCLUSION: (1) Expression of miR-140-3p was significantly down-regulated in knee osteoarthritis group. Significant differences in miR-140-3p expression were detected between non-knee osteoarthritis group and knee osteoarthritis group (P < 0.05). No significant difference in miR-140-3p expression was determined among healthy control group, gouty arthritis group and rheumatoid arthritis group (P > 0.05). (2) The miR-140-3p expression in the healthy control group was 11.4 times that in the knee osteoarthritis group. The expression of miR-140-3p decreased with the increase of the severity of osteoarthritis. (3) Spearman rank correlation analysis suggested that the expression of miR-140-3p was negatively correlated with osteoarthritis severity. (4) Results suggest that the expression of miR-140-3p in synovial fluid can reflect the progression of knee osteoarthritis to a certain extent.
