摘要:


文题释义:
巨噬细胞极化:巨噬细胞受到外界刺激后表现出特定功能表型(促炎性M1型巨噬细胞、抗炎性M2型巨噬细胞),这种对遇到的微环境刺激和信号做出反应的过程称为巨噬细胞极化。M1巨噬细胞分泌白细胞介素1β等促炎细胞因子,M2巨噬细胞分泌白细胞介素10等抗炎细胞因子。
高通量测序:能同时检测多条序列,机制是:将DNA随机打断成无数小片段(250-300 bp),通过建库把这些DNA片段富集起来,然后放入测序仪中测序,测序仪中有着可以让DNA片段独立附着的区域,可以一次检测所有附着的DNA序列,最后将小片段拼接成长片段。高通量测序的特点是一次能够检测大量序列,显著提高了测序效率。 

背景:国医大师韦贵康所创痛安汤治疗膝骨关节炎的疗效显著,但作用机制尚不明确。
目的:探讨痛安汤通过调控大鼠滑膜巨噬细胞极化治疗膝骨关节炎的作用机制。
方法:①通过miRNA高通量测序与PCR分析正常大鼠与膝骨关节炎大鼠膝关节滑膜组织中差异miRNA表达,通过数据库预测miR-27a靶基因,采用荧光素酶实验检测miR-27a与靶基因结合情况。②采用随机数字表法将68只SD大鼠随机分为正常对照组(n=16)、模型组(n=16)、miR-27a过表达组(n=12)、痛安汤组(n=12)、痛安汤+miR-27a抑制组(n=12)。除正常对照组外,其他4组通过膝关节腔注射碘乙酸钠的方法建立右侧膝骨关节炎模型,造模后第2天,miR-27a过表达组、痛安汤+miR-27a抑制组右侧膝关节腔内分别注射
miR-27a模拟物、miR-27a抑制物,1次/d,连续注射5 d;造模后第15天,痛安汤组、痛安汤+miR-27a抑制组给予痛安汤灌胃,其他3组给予生理盐水灌胃,1次/d,连续14 d。灌胃干预结束后,分别进行行为学检测、X射线片检查、膝关节滑膜组织与软骨组织苏木精-伊红染色以及膝关节滑膜组织的免疫荧光染色、RT-PCR、Western blot检测。
结果与结论:①miRNA高通量测序显示膝骨关节炎大鼠滑膜组织中miR-27a低表达,miR-27a的靶基因为核因子κB,荧光素酶实验显示二者能够相互结合。②行为学检测显示,miR-27a过表达或痛安汤可缓解膝骨关节炎大鼠的关节功能障碍,miR-27a抑制可拮抗痛安汤的作用。X射线片与苏木精-伊红染色结果显示,miR-27a过表达或痛安汤可减轻膝骨关节炎程度,miR-27a抑制削弱了痛安汤的治疗作用。RT-PCR与Western blot检测结果显示,与正常对照组比较,模型组白细胞介素10表达均降低(P < 0.05),基质金属蛋白酶13、白细胞介素1β、核因子κB表达均升高(P < 0.05);miR-27a过表达或痛安汤可不同程度地逆转膝骨关节炎造模导致的上述指标变化,而miR-27a抑制会削弱痛安汤的作用。免疫荧光染色结果显示,模型组CD86蛋白表达高于正常对照组(P < 0.05),CD206蛋白表达低于正常对照组(P < 0.05);miR-27a过表达组、痛安汤组CD86蛋白表达低于模型组(P < 0.05),CD206蛋白表达高于模型组(P < 0.05);痛安汤+miR-27a抑制组CD86高于痛安汤组(P < 0.05),CD206蛋白表达低于痛安汤组(P < 0.05)。③结果表明,痛安汤通过促进miR-27a表达、抑制核因子κB表达来调控巨噬细胞极化,改善膝关节功能,进一步治疗膝骨关节炎。

Abstract: BACKGROUND: Developed by the esteemed Chinese medicine master Wei Guikang, Tongan Decoction has proven highly effective in treating knee osteoarthritis. However, the mechanism of action is yet unclear. 
OBJECTIVE: To elucidate how Tongan Decoction modulates synovial macrophage polarization as a therapeutic strategy for knee osteoarthritis in a rat model.
METHODS: (1) We employed high-throughput microRNA sequencing and polymerase chain reaction to analyze the differentially expressed miRNA in synovial macrophages of normal and knee osteoarthritis rats. Predicted target genes of miR-27a were identified using bioinformatics databases, with subsequent validation through luciferase assays. A total of 68 Sprague-Dawley rats were randomly divided into normal control group (n=16), model group (n=16), miR-27a overexpression group (n=12), Tongan Decoction group (n=12), and Tongan Decoction+miR-27a inhibition group (n=12). The miR-27a overexpression group and the Tongan Decoction+miR-27a inhibition group were injected with miR-27a mimic and miR-27a inhibitor in the right knee joint cavity, respectively, once daily for 5 continuous days. On the 15th day after modeling, the Tongan Decoction group and the Tongan Decoction+miR-27a inhibition group were given Tongan Decoction by gastric lavage, and the other three groups were given saline by gastric lavage, once daily for 14 continuous days. After administration, behavioral tests, X-rays, hematoxylin-eosin staining of synovial and cartilage tissues of the knee joint and immunofluorescence staining of synovial tissues of the knee joint, RT-PCR, and Western blot were performed.
RESULTS AND CONCLUSION: High-throughput sequencing of miRNA showed low expression of miR-27a in synovial tissues of rats with knee osteoarthritis. The target gene of miR-27a was nuclear factor κB, and luciferase assay showed that the two could bind to each other. Behavioral assays showed that miR-27a overexpression or Tongan Decoction alleviated joint dysfunction in rats with knee osteoarthritis, and miR-27a inhibition antagonized the effect of Tongan Decoction. X-ray films and hematoxylin-eosin staining showed that miR-27a overexpression or Tongan Decoction reduced the degree of knee osteoarthritis and miR-27a inhibition weakened the therapeutic effect of Tongan Decoction. The results of RT-PCR and western blot assay showed that compared with the normal control group, the expression of interleukin 10 was reduced in the model group (P < 0.05), and the expression of matrix metalloproteinase 13, interleukin 1β, and nuclear factor κB was elevated in the model group (P < 0.05). miR-27a overexpression or Tongan Decoction could differently reverse the changes in the above-mentioned indexes, while miR-27a inhibition weakened the effect of Tongan Decoction. Immunofluorescence staining results showed that CD86 protein expression in the model group was higher than that in the normal control group (P < 0.05), and CD206 protein expression was lower than that in the normal control group (P < 0.05); miR-27a overexpression group and Tongan Decoction had lower CD86 protein expression than that in the model group (P < 0.05), and higher CD206 protein expression than that in the model group (P < 0.05); in the Tongan Decoction+miR-27a inhibition group, CD86 protein expression was higher (P < 0.05) and CD206 protein expression was lower than that in the Tongan Decoction group (P < 0.05). Tongan Decoction mitigates knee osteoarthritis by upregulating miR-27a expression and suppressing nuclear factor κB activity, which improves knee joint function and further treats knee osteoarthritis.
