摘要:

背景:低氧诱导因子1α和粒细胞-巨噬细胞集落刺激因子在骨性关节炎炎症环境下具有促进骨性关节炎发展的作用。

目的:观察膝骨性关节炎软骨组织中低氧诱导因子1α和粒细胞-巨噬细胞集落刺激因子的表达水平并分析其临床意义。
方法:收集行膝关节置换的膝骨性关节炎患者32例,取其软骨组织样本作为骨性关节炎组。采用实时定量PCR和Western blot检测样本中低氧诱导因子1α和粒细胞-巨噬细胞集落刺激因子的mRNA和蛋白水平;采用改良Mankin评分对骨性关节炎患者膝损伤程度进行评估,对低氧诱导因子1α和粒细胞-巨噬细胞集落刺激因子的mRNA表达水平和改良Mankin评分做相关分析。选取10例同时期股骨颈骨折患者作为对照组。
结果与结论:骨性关节炎组患者低氧诱导因子1α和粒细胞-巨噬细胞集落刺激因子的基因及蛋白表达水平均显著高于对照组(P < 0.05)。年龄> 60岁的骨性关节炎患者低氧诱导因子1α的mRNA和蛋白水平,粒细胞-巨噬细胞集落刺激因子的基因水平均显著高于≤60岁的骨性关节炎患者(P < 0.05)。继发性的骨性关节炎患者2种因子的基因和蛋白水平均显著高于原发性骨性关节炎患者(P < 0.05)。不同改良Mankin病理评分分级之间,低氧诱导因子1α和粒细胞-巨噬细胞集落刺激因子的基因和蛋白水平差异均有显著性意义(P < 0.05),程度越重,其表达水平越高。骨性关节炎组患者低氧诱导因子1α和粒细胞-巨噬细胞集落刺激因子的mRNA相对表达量与改良Mankin评分之间均存在正相关(r=0.83,P < 0.05;r=0.80,P < 0.05)。结果提示膝关节骨性关节炎软骨组织中低氧诱导因子1α和粒细胞-巨噬细胞集落刺激因子的表达水平上调,且在多种病理参数分布上存在差异,其在膝骨性关节炎的致病机制中起了重要作用。

Abstract:

BACKGROUND: Hypoxia-inducible factor 1α and granulocyte-macrophage colony stimulating factor can promote the development of osteoarthritis under inflammatory conditions.

OBJECTIVE: To explore the expression of hypoxia inducible factor 1α and granulocyte-macrophage colony-stimulating factor in knee osteoarthritis cartilage tissue and to analyze its clinical significance.
METHODS: Thirty-two patients with knee osteoarthritis who underwent knee replacement were selected and cartilage tissues were obtained as knee osteoarthritis group. Another 10 patients with femoral neck fractures served as controls. mRNA and protein levels of hypoxia inducible factor 1α and granulocyte-macrophage colony-stimulating factor in the cartilage tissue were detected by real-time PCR and western blot, respectively. Modified Mankin score was used to assess knee damage in knee osteoarthritis patients. Relationship between mRNA levels of hypoxia inducible factor 1α and granulocyte-macrophage colony-stimulating factor and modified Mankin scores were analyzed.
RESULTS AND CONCLUSION: Hypoxia inducible factor 1α and granulocyte-macrophage colony-stimulating factor gene and protein expressions were significantly higher in the knee osteoarthritis group than the control group, in knee osteoarthritis patients aged > 60 years than patients ≤ 60 years (P < 0.05), as well as higher in secondary knee osteoarthritis patients than primary osteoarthritis patients (P < 0.05). Hypoxia inducible factor 1α and granulocyte-macrophage colony-stimulating factor protein levels and gene levels had statistically significant differences between different pathological grades (P < 0.05); moreover, the severer osteoarthritis, the higher expression levels. Hypoxia inducible factor 1α and granulocyte-macrophage colony-stimulating factor mRNA expression of knee osteoarthritis patients were positively correlated with the modified Mankin scores (r=0.83, P < 0.05; r=0.80, P < 0.05). These findings indicate that hypoxia inducible factor 1α and granulocyte-macrophage colony-stimulating factor expression levels are increased in the knee cartilage tissue of osteoarthritis patients, which display a distribution difference among a variety of pathological parameters and play an important role in the pathogenesis of knee osteoarthritis.
