摘要:

文题释义:
SOX9:是调控软骨分化的主要基因,在所有分化的软骨细胞和软骨前细胞中均有表达,其对于建立软骨生长板及促进正常的软骨内成骨都是必需的,SOX9过表达时能抑制软骨细胞的肥大,负向调节软骨细胞肥大进程。因此,SOX9是参与骨关节炎软骨修复合成的重要介质,也是经典的软骨修复因子,在软骨的修复过程中起到重要的调节作用。
白细胞介素1β:是一种炎性细胞因子,其可通过扰乱软骨代谢平衡、抑制软骨细胞增殖、诱导软骨细胞凋亡、促进软骨基质降解,促进滑膜炎症发展,从而加速骨关节炎进程。
背景:前期研究发现,补肾调肝方能明显改善骨关节炎症状,临床疗效肯定,但缺乏相关的实验依据。 
目的:探索补肾调肝方含药血清对白细胞介素1β诱导的软骨细胞凋亡的影响及其分子机制。
方法:取传代培养的第3代大鼠软骨细胞,随机分为4组:PBS组(对照组)、10 μg/L 白细胞介素1β组、10 μg/L 白细胞介素1β+5%补肾调肝方含药血清(5%补肾调肝方含药血清组)及10 μg/L 白细胞介素1β+10%补肾调肝方含药血清(10%补肾调肝方含药血清组),分别处理软骨细胞 24 h。采用流式细胞术检测细胞凋亡;蛋白印迹分析SOX9、NF-κB P65和p-NF-κB P65蛋白的表达水平。实验方案经广州中医药大学动物实验伦理委员会批准。
结果与结论:①与对照组相比,白细胞介素1β可诱导软骨细胞的凋亡(P < 0.05);②与白细胞介素1β组比,5%和10%补肾调肝方含药血清组软骨细胞的凋亡率均下降,且呈剂量依赖性(均P < 0.05);③与对照组相比,白细胞介素1β组SOX9的表达明显降低(P < 0.05),p-P65/P65明显升高(P < 0.05);5%和10%补肾调肝方含药血清组SOX9的表达明显高于白细胞介素1β组(P < 0.05),10%补肾调肝方含药血清组p-P65/P65显著低于白细胞介素1β组(P < 0.05);④结果说明,补肾调肝方可能是通过调控SOX9/NF-κB抑制白细胞介素1β的诱导大鼠骨关节软骨细胞凋亡,起到缓解关节软骨退变的作用。

Abstract: BACKGROUND: Previous studies have found that Bushen Tiaogan prescription can significantly improve the symptoms of osteoarthritis, with a positive clinical effect, but there is still a lack of relevant experimental evidence.
OBJECTIVE: To explore the effect of serum containing Bushen Tiaogan prescription on interleukin (IL)-1β-induced chondrocyte apoptosis and its molecular mechanism. 
METHODS: Passage 3 chondrocytes from rats were randomly divided into four groups: PBS group (control group), 10 μg/L IL-1β group, 10 μg/L IL-1β+5% Bushen Tiaogan prescription group, 10 μg/L IL-1β+10% Bushen Tiaogan prescription group, in which chondrocytes were treated for 24 hours. Flow cytometry was used to detect cell apoptosis, and western blot was used to analyze the expression levels of SOX9, NF-κB P65 and p-NF-κB P65 proteins. An approval was obtained from the Animal Experimental Ethics Committee of Guangzhou University of Chinese Medicine. 
RESULTS AND CONCLUSION: Compared with the control group, IL-1β induced chondrocyte apoptosis (P < 0.05). Compared with the IL-1β group, the apoptosis rate of chondrocytes in the 10 μg/L IL-1β+5% Bushen Tiaogan prescription and 10 μg/L IL-1β+10% Bushen Tiaogan prescription groups significantly decreased in a dose-dependent manner (P < 0.05). Compared with the control group, the expression of SOX9 in the IL-1β group was significantly lower than that of the control group (P < 0.05), and the expression of p-P65/P65 was significantly higher than that of the control group (P < 0.05). The expression of SOX9 in the        10 μg/L IL-1β+5% Bushen Tiaogan prescription and 10 μg/L IL-1β+10% Bushen Tiaogan prescription groups was significantly higher than that in the IL-1β group (P < 0.05), and the expression of p-P65/P65 in the 10 μg/L IL-1β+10% Bushen Tiaogan prescription group was significantly lower than that in the IL-1β group  (P < 0.05). To conclude, Bushen Tiaogan prescription may inhibit IL-1β-induced apoptosis of rat osteoarticular chondrocytes by regulating SOX9/NF-κB, and play a role in alleviating articular cartilage degeneration.

Key words: osteoarthritis, Bushen Tiaogan prescription, articular cartilage, SOX9/NF-κB
