摘要:


文题释义:

痛风性关节炎:是一种由持续高水平血尿酸引起的关节或关节周围组织内单钠尿酸晶体沉积所触发的自身炎症性疾病,其临床表现为发病部位的红肿、剧烈疼痛以及活动受限,如不积极治疗,则会导致骨代谢紊乱和骨破坏,最终引起关节畸形或损伤。
NOD样受体热蛋白结构域相关蛋白3(Nod-like receptor pyrin domain-containing protein 3,NLRP3):是一种由NLRP3感受器蛋白、斑点样蛋白以及效应器半胱氨酸天冬氨酸蛋白酶组成的胞内多蛋白复合体。NLRP3炎性小体的活化与包括痛风在内多种炎症性疾病的发生与发展有着密切的关系。


背景:研究发现NLRP3炎症小体的激活是痛风性关节炎发病的重要因素,通过调控PTEN诱导激酶1(PTEN-induced kinas 1,PINK1)/Parkin信号通路能有效抑制NLPR3炎性小体的活化。

目的:探究独活寄生汤对PINK1/Parkin/NLRP3信号通路的影响。
方法:①动物实验:将雄性SD大鼠随机分为对照组、模型组、阳性对照组(秋水仙片0.3 mg/kg)和独活寄生汤低、中、高剂量组(分别给予6.9,13.8,27.6 g/kg),除对照组外其余各组大鼠通过右后踝关节腔注射尿酸单钠盐晶体混悬液构建大鼠痛风性关节炎模型。②细胞实验:将人单核细胞(THP-1)分为空白对照组、模型组、独活寄生汤含药血清组、PINK1 siRNA+独活寄生汤含药血清组,除空白对照组外其余各组细胞采用尿酸钠刺激建立体外痛风性关节炎模型。③观察大鼠踝关节肿胀度、关节周径、步态评分、关节炎症指数和病理分级程度;酶联免疫吸附法检测尿酸、C-反应蛋白、NLRP3和白细胞介素1β水平;免疫印迹法检测PINK1/Parkin/NLRP3通路相关蛋白表达水平;四甲基偶氮唑蓝法检测细胞活性;免疫荧光双染检测线粒体自噬水平;免疫荧光检测NLRP3和白细胞介素1β表达。

结果与结论:①与对照组比较,模型组大鼠在6-48 h的踝关节肿胀度、踝关节周径升高(P < 0.05),在24和48 h时的步态评分与关节炎症指数升高(P < 0.05),血清尿酸和C-反应蛋白水平、病理分级程度、滑膜组织中PINK1、Parkin和NLRP3蛋白表达及白细胞介素1β水平均升高(P < 0.05);与模型组比较,独活寄生汤各剂量组大鼠上述指标中除PINK1和Parkin蛋白表达升高(P < 0.05)外,其他指标均降低(P < 0.05)。②与模型组比较,独活寄生汤含药血清组细胞NLRP3活性、白细胞介素1β水平和线粒体外膜转位蛋白20(TOM20)蛋白水平降低(P < 0.05),而增殖抑制率、PINK1、Parkin和LC3B蛋白水平增加(P < 0.05);细胞线粒体自噬水平升高(P < 0.05),而NLRP3和白细胞介素1β蛋白水平降低(P < 0.05)。③与独活寄生汤含药血清组相比,PINK1 siRNA+独活寄生汤含药血清组细胞线粒体自噬水平降低(P < 0.05),NLRP3和白细胞介素1β表达水平升高(P < 0.05)。④结果表明,独活寄生汤通过调控PINK1/Parkin信号通路抑制NLRP3炎性小体活化,进而对痛风性关节炎起到治疗作用。

Abstract: BACKGROUND: The activation of NOD-like receptor thermal protein domain associated protein 3 (NLRP3) inflammasome has been found to be an important factor in the pathogenesis of gouty arthritis, and the activation of NLPR3 inflammasome can be effectively inhibited by regulating the PTEN-induced kinas 1 (PINK1)/Parkin signaling pathway.
OBJECTIVE: To investigate the effect of Duhuo Jisheng Decoction on the PINK1/Parkin/NLRP3 signaling pathway.
METHODS: (1) Animal experiment: Male Sprague-Dawley rats were randomly divided into control group, model group, positive control group (Qiushuixian tablets 0.3 mg/kg), and low-, medium-, and high-dose Duhuo Jisheng Decoction groups (6.9, 13.8, and 27.6 g/kg, respectively). A rat gouty arthritis model was constructed by injecting monosodium urate crystal suspension into the right hind ankle joint cavity of rats in all the groups except for the control group. (2) Cell experiment: Human monocytes (THP-1) were divided into blank control group, model group, Duhuo Jisheng Decoction-containing serum group, and PINK1 siRNA+Duhuo Jisheng Decoction-containing serum group. The cells in each group except the blank control group were stimulated with sodium urate to establish an in vitro gouty arthritis model. (3) The swelling degree, joint circumference, gait score, joint inflammation index and degree of pathological grading in the ankle joints of rats were observed. Enzyme-linked immunosorbent assay was used to detect the levels of uric acid, C-reactive protein, NLRP3, and interleukin 1β. Immunoblotting assay was used to detect the levels of proteins related to the PINK1/Parkin/NLRP3 pathway. Tetramethyl azolidine blue assay was used to detect cell activity. Immunofluorescent double staining was performed to detect the level of mitophagy. Immunofluorescence was used to detect the expression of NLRP3 and interleukin 1β. 
RESULTS AND CONCLUSION: (1) Compared with the control group, rats in the model group showed elevated ankle swelling and ankle circumference at 6-48 hours (P < 0.05), elevated gait scores and joint inflammation indexes at 24 and 48 hours (P < 0.05), elevated serum uric acid and C-reactive protein levels, degree of pathological classification, expression of PINK1, Parkin, and NLRP3 proteins, and interleukin 1β level in synovial tissues (P < 0.05). Compared with the model group, the protein expression levels of PINK1 and Parkin in all the Duhuo Jisheng Decoction groups were elevated, while the levels of the other indexes were decreased (P < 0.05). (2) Compared with the model group, NLRP3 activity, interleukin 1β level and mitochondrial outer membrane translocator protein 20 protein level in the Duhuo Jisheng Decoction-containing serum group were decreased (P < 0.05), while the proliferation inhibition rate, PINK1, Parkin and LC3B protein level were increased (P < 0.05). Compared with the model group, the mitochondrial autophagy level of cells in the Duhuo Jisheng Decoction-containing serum group was elevated (P < 0.05), while NLRP3 and interleukin 1β protein levels were decreased (P < 0.05). (3) Compared with the Duhuo Jisheng Decoction-containing serum group, the mitochondrial autophagy level of cells in the PINK1 siRNA+Duhuo Jisheng Decoction-containing serum group was decreased (P < 0.05), and the expression levels of NLRP3 and interleukin 1β were elevated (P < 0.05). To conclude, Duhuo Jisheng Decoction inhibits the activation of NLRP3 inflammasome by regulating the PINK1/Parkin signaling pathway, thereby exerting a therapeutic effect on gouty arthritis.
