摘要:


文题释义:
雷公藤甲素:又称雷公藤内酯,是从雷公藤根中提取的一种二萜类三环氧化物,分子式是C20H24O6,相对分子质量为360.40,难溶于水,易溶于甲醇、二甲基亚砜、无水乙醇、乙酸乙酯、氯仿等,具有免疫抑制、抗炎、抗增殖和抗肿瘤的药理作用。
网络药理学:能够基于药物的主要成分,将疾病与药物成分的作用靶点进行网络分析,从多途径强调对相关信号通路的调节,提高药物的治疗效果,降低不良反应,从而提高新药临床试验的成功率,节省药物的研发费用。

背景:骨关节炎是一种具有致残性的慢性关节退化性疾病,以持续性炎症和软骨破坏为主要病理特征。雷公藤甲素可用于治疗各种慢性关节疾病,但雷公藤甲素治疗骨关节炎的作用机制尚未明确。
目的:通过网络药理学筛选雷公藤甲素治疗骨关节炎的有效靶点,并利用骨关节炎模型探讨雷公藤甲素对骨关节炎的治疗效果。
方法:利用网络药理学预测雷公藤甲素治疗骨关节炎的潜在靶点和信号通路,之后应用分子对接技术对核心靶点进行验证。采用前交叉韧带横断术建立大鼠骨关节炎模型,造模8周后予雷公藤甲素及玻璃酸钠关节腔注射给药6周。干预6周后进行苏木精-伊红染色及番红O-固绿染色观察大鼠膝关节病理变化;ELISA法检测大鼠血清中炎症因子的水平;免疫组织化学染色法检测大鼠关节软骨中蛋白聚糖、含Ⅰ型血小板反应蛋白的解聚素金属蛋白酶5、Ⅱ型胶原蛋白、基质金属蛋白酶13的蛋白表达。
结果与结论:①网络药理学结果表明,雷公藤甲素的作用靶点可能与抑制白细胞介素6、肿瘤坏死因子ɑ、白细胞介素1β、基质金属蛋白酶9等因子的释放,及NF-κB/JAK2-STAT3信号通路的过度活化相关;②雷公藤甲素可减轻骨关节炎大鼠的关节肿胀程度;改善关节软骨组织病理状态,维持软骨结构;降低骨关节炎大鼠血清中白细胞介素6、肿瘤坏死因子α、白细胞介素1β、基质金属蛋白酶9、基质金属蛋白酶3的水平;减少关节软骨中基质金属蛋白酶13和含Ⅰ型血小板反应蛋白的解聚素金属蛋白酶5的蛋白表达,增加软骨中Ⅱ型胶原和蛋白聚糖的表达,达到保护软骨的作用。

Abstract: BACKGROUND: Osteoarthritis is a chronic degenerative disease of the joints that can lead to disability. Its main pathological features are persistent inflammation and cartilage destruction. Triptolide has been used to treat a variety of chronic joint diseases. However, the mechanism of triptolide in the treatment of osteoarthritis has not been clarified
OBJECTIVE: To identify the effective targets of triptolide in the treatment of osteoarthritis by network pharmacology, and to investigate the therapeutic effect of triptolide on osteoarthritis in the osteoarthritis model.
METHODS: Network pharmacology was used to anticipate the potential targets and signaling pathways of triptolide in the treatment of osteoarthritis, and molecular docking technology was used to validate the core targets. A rat osteoarthritis model was established by anterior cruciate ligament transection. Eight weeks after modeling, the rats were administered with triptolide and sodium hyaluronate by intra-articular injection for 6 weeks. After 6 weeks of intervention, the pathological changes in rat knee joints were observed by hematoxylin-eosin staining and safranin O-fast green staining. The levels of inflammatory factors in rat serum were detected by enzyme-linked immunosorbent assay. The expression of aggrecan, type I platelet-responsive protein-containing desmoglein metalloproteinase 5, type II collagen and matrix metalloproteinase 13 proteins in rat articular cartilage was tested by immunohistochemical staining.
RESULTS AND CONCLUSION: (1) The results of network pharmacology indicated that the target of triptolide may be related to the inhibition of the release of factors such as interleukin 6, tumor necrosis factor ɑ, interleukin 1β, matrix metalloproteinase 9, and the over-activation of the nuclear factor-κB/JAK2-STAT3 signaling pathway. (2) Triptplide could reduce the degree of joint swelling in osteoarthritic rats; pathologically improve the articular cartilage and maintain the cartilage structure; decrease the serum levels of interleukin 6, tumor necrosis factor ɑ, interleukin 1β, matrix metalloproteinase 9, and matrix metalloproteinase 3 in osteoarthritic rats; reduce the protein expression of matrix metalloproteinase 13 and type I platelet-responsive protein-containing desmoglein metalloproteinase 5 in the articular cartilage; and increase the expression of type II collagen and aggrecan in the cartilage, thereby achieving cartilage protection.
