背景:透明质酸钠是一种治疗骨关节炎的有效手段,但其机制尚不清楚。有研究表明基质金属蛋白酶1,3,9和基质金属蛋白酶组织抑制剂1,2表达失调对骨关节炎有重要影响。目的:观察关节腔内注射透明质酸钠对兔创伤性骨关节炎模型软骨中基质金属蛋白酶1,3,9和基质金属蛋白酶组织抑制剂1,2表达的影响。方法:采用单侧前交叉韧带切断法构建创伤性骨关节炎模型兔,造模后4周关节腔注射体积分数1%透明质酸钠0.3 mL,每周1次,连续5周,设为透明质酸钠组,同时设模型组和正常对照组作对比。术后11周麻醉处死动物,获取软骨并提取总RNA,用实时聚合酶链反应分析各组软骨内基质金属蛋白酶1,3,9和基质金属蛋白酶组织抑制剂1,2 mRNA表达。结果与结论:与模型组相比,透明质酸钠组经关节腔内注射透明质酸钠软骨损伤范围和程度均减轻(P <0.01),软骨组织学评分明显降低(P <0.05)。模型组软骨内基质金属蛋白酶1,3,9 mRNA表达增强,基质金属蛋白酶组织抑制剂1,2 mRNA表达下调,而透明质酸钠组软骨中基质金属蛋白酶1,3,9,基质金属蛋白酶组织抑制剂1,2 mRNA的表达并无显著变化。结果说明,基质金属蛋白酶1,3,9和基质金属蛋白酶组织抑制剂1,2参与了创伤性骨关节炎软骨退变过程,虽然关节腔内注射透明质酸钠可以延缓创伤性骨关节炎软骨退变,但透明质酸钠并不是通过调节上述因子的表达来发挥修复作用的,具体机制有待进一步研究证实。
揹景:透明質痠鈉是一種治療骨關節炎的有效手段,但其機製尚不清楚。有研究錶明基質金屬蛋白酶1,3,9和基質金屬蛋白酶組織抑製劑1,2錶達失調對骨關節炎有重要影響。目的:觀察關節腔內註射透明質痠鈉對兔創傷性骨關節炎模型軟骨中基質金屬蛋白酶1,3,9和基質金屬蛋白酶組織抑製劑1,2錶達的影響。方法:採用單側前交扠韌帶切斷法構建創傷性骨關節炎模型兔,造模後4週關節腔註射體積分數1%透明質痠鈉0.3 mL,每週1次,連續5週,設為透明質痠鈉組,同時設模型組和正常對照組作對比。術後11週痳醉處死動物,穫取軟骨併提取總RNA,用實時聚閤酶鏈反應分析各組軟骨內基質金屬蛋白酶1,3,9和基質金屬蛋白酶組織抑製劑1,2 mRNA錶達。結果與結論:與模型組相比,透明質痠鈉組經關節腔內註射透明質痠鈉軟骨損傷範圍和程度均減輕(P <0.01),軟骨組織學評分明顯降低(P <0.05)。模型組軟骨內基質金屬蛋白酶1,3,9 mRNA錶達增彊,基質金屬蛋白酶組織抑製劑1,2 mRNA錶達下調,而透明質痠鈉組軟骨中基質金屬蛋白酶1,3,9,基質金屬蛋白酶組織抑製劑1,2 mRNA的錶達併無顯著變化。結果說明,基質金屬蛋白酶1,3,9和基質金屬蛋白酶組織抑製劑1,2參與瞭創傷性骨關節炎軟骨退變過程,雖然關節腔內註射透明質痠鈉可以延緩創傷性骨關節炎軟骨退變,但透明質痠鈉併不是通過調節上述因子的錶達來髮揮脩複作用的,具體機製有待進一步研究證實。

Abstract BACKGROUND: Sodium hyaluronate is an effective treatment for osteoarthritis, but the underlying mechanism remains unclear. There is evidence that abnormal expressions of matrix metaloproteinase (MMP)-1, -3 and -9 and tissue inhibitor of metaloproteinase (TIMP)-1 and -2 show great effects on osteoarthritis. OBJECTIVE: To assess the influence of intra-articular injection of sodium hyaluronate on expressions of MMPs-1, 3, 9 and tissue inhibitor of TIMPs-1, 2 in the rabbit cartilage after osteoarthritis. METHODS: Twenty-four mature New Zealand white rabbits were divided into normal control, model, and sodium hyaluronate groups. The model and sodium hyaluronate groups underwent unilateral anterior cruciate ligament transection, and rabbits in the sodium hyaluronate group received 0.3 mL of 1% sodium hyaluronate via intra-articular injection at 4 weeks after modeling, once a week for 5 weeks. At 11 weeks folowing surgery, the rabbits were kiled and the cartilage was harvested to extract total RNA. mRNA expressions of MMPs-1, 3, 9 and TIMPs-1, 2 in the cartilage were analyzed using real-time PCR for each group. RESULTS AND CONCLUSION:Compared with the model group, the range and extent of cartilage damage was reduced in the sodium hyaluronate group (P < 0.01), and Mankin scores were noticeably decreased (P < 0.05). In the cartilage, mRNA expressions of MMPs-1, 3, 9 were enhanced and mRNA expressions of TIMPs-1, 2 were down-regulated in the model group. However, the mRNA expression levels of MMPs-1, 3, 9 and TIMPs-1, 2 in the articular cartilage were not obviously changed in the sodium hyaluronate group. These results suggest that MMPs-1, 3, 9 and TIMPs-1, 2 are involved in the progression of osteoarthritis and the therapeutic mechanism of sodium hyaluronate is not realized through the down-regulation of their expressions during development of osteoarthritis. Sodium hyaluronate for treatment of osteoarthritis is a complex process and the underlying mechanisms require further investigation.
