摘要:

文题释义:
骨关节炎:是一种骨科最常见的退行性病变,主要病理特征有软骨进行性退变、滑膜炎症以及软骨下骨增生。膝关节是骨关节炎最常累及的关节,多见于中老年人,尤其是女性。
白芍总苷:是中药白芍的主要有效成分,现代药理学研究结果显示其有很好的抗炎止痛、免疫调节等作用。白芍作为治疗骨关节炎常用药物之一,其对骨关节炎软骨炎症和退变的影响以及其潜在的作用机制仍不明确。

背景:软骨退变是骨关节炎的病理表现之一,在骨关节炎发病进展中起着重要作用。白芍总苷是白芍的有效成分,有很强的抗炎、止痛、免疫调节作用,然而其对骨关节炎软骨细胞炎症及退变的影响仍不明确。
目的:观察白芍总苷对骨关节炎软骨细胞中白细胞介素1β、肿瘤坏死因子α及基质金属蛋白酶13水平的影响。
方法:应用胶原酶消化法从膝关节置换手术废弃的软骨组织中提取软骨细胞,采用CCK-8法检测不同浓度白芍总苷对软骨细胞增殖活力的影响,然后将软骨细胞分为5组:空白组、脂多糖干预组(10 mg/L脂多糖)、低浓度白芍总苷组(10 μmol/L白芍总苷+10 mg/L脂多糖)、中浓度白芍总苷组(20 μmol/L白芍总苷+10 mg/L脂多糖)、高浓度白芍总苷组(50 μmol/L白芍总苷+10 mg/L脂多糖),干预24 h后,采用qPCR和Western blot检测各组细胞中白细胞介素1β、肿瘤坏死因子α及基质金属蛋白酶13表达变化。
结果与结论:①10,20,50 μmol/L白芍总苷可以显著刺激软骨细胞增殖,过高浓度白芍总苷则有明显抑制作用;②脂多糖诱导可以显著提高软骨细胞中白细胞介素1β、肿瘤坏死因子α及基质金属蛋白酶13的表达量(P < 0.01),加入白芍总苷可以显著降低软骨细胞中白细胞介素1β、肿瘤坏死因子α及基质金属蛋白酶13表达量(P < 0.05,P < 0.01),且呈浓度依赖性;③结果显示,适宜浓度白芍总苷对骨关节炎软骨细胞具有明显的抗炎、延缓细胞外基质丢失的特性。

Abstract: BACKGROUND: Cartilage degeneration is one of the most characteristic pathological manifestations of osteoarthritis, which plays an important role in the pathogenesis of osteoarthritis. The total glucosides of paeony (TGP) is the effective components of white paeony root, which has strong anti-inflammatory, analgesic and immunomodulatory effects. However, its effect on inflammation and degeneration of cartilage is still unclear. 
OBJECTIVE: To observe the effects of TGP on interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α) and matrix metalloproteinase-13 (MMP-13) in osteoarthritic chondrocytes in osteoarthritis. 
METHODS: Chondrocytes were extracted from the cartilage tissue discarded by knee replacement surgery by collagenase digestion. The effects of different concentrations on the proliferation of chondrocytes were detected by cell counting kit-8 method. The cultured cells were further divided into five groups: blank group, lipopolysaccharide (10 mg/L) intervention group, low concentration TGP group (10 μmol/L TGP+10 mg/L lipopolysaccharide), medium concentration TGP group (20 μmol/L TGP+10 mg/L lipopolysaccharide) and high concentration TGP group (50 μmol/L TGP+10 mg/L lipopolysaccharide). Except for the normal group, the other four groups were induced with lipopolysaccharide to induce inflammation. Real-time quantitative PCR and western blot assay were used to detect the expression of IL-1β, TNF-α and MMP-13 in each group at 24 hours after intervention. 
RESULTS AND CONCLUSION: TGP of 10, 20 and 50 μmol/L significantly stimulated the proliferation of chondrocytes, and excessive concentration of TGP significantly inhibited the proliferation. Chondrocytes with lipopolysaccharide induction significantly increased the expression of IL-1β, TNF-α and MMP-13 (P < 0.01), while TGP could significantly reduce IL-1β, TNF-α and MMP-13 expression in lipopolysaccharide-induced chondrocytes in a concentration-dependent manner (P < 0.05, P < 0.01). To conclude, TGP has an obvious anti-inflammatory effect and delays extracellular matrix loss in chondrocytes.
