摘要:

文题释义:

膝骨关节炎:是一种以膝关节软骨退变、破坏和骨质增生为主要特征的慢性关节病,多患于中老年人群,主要表现为膝关节疼痛,上下楼梯时疼痛加重,休息后缓解,局部肿胀,活动受限,晚期膝关节畸形,严重影响患者的生活质量。

雌激素:主要由卵巢分泌,分泌的雌激素进入血液循环发挥生物学效应,妇女绝经后卵巢功能衰退,雌激素分泌减少从而诱发膝骨关节炎。

背景:膝骨关节炎是最常见的退行性关节疾病,其发病率和致残率高,已严重影响患者的生活质量。研究发现,补肾健脾活血中药能够改善膝骨关节炎临床症状,但其具体机制仍未阐明。

目的:通过膝骨关节炎去势大鼠模型研究补肾健脾活血中药调节IL-1β/ERRα/SOX9/Col2α1信号通路治疗大鼠膝骨关节炎的作用机制。

方法6月龄SD雌性大鼠,随机分为空白对照组、模型组、实验组和阳性对照组,模型组、实验组和阳性对照组摘除卵巢及切除交叉韧带和内侧半月板制作去势大鼠膝骨关节炎模型,术后2周实验组采用补肾健脾活血中药灌胃,阳性对照组采用塞来昔布胶囊灌胃,空白对照组和模型组以生理盐水灌胃。连续灌胃6周后取血清及膝关节软骨组织,采用ELISA检测血清雌二醇含量,分别采用荧光定量PCRWestern blot检测关节软骨组织中IL-1β/ERRα/SOX9/Col2α1信号通路表达水平。

结果与结论:与空白对照组比较,模型组白细胞介素1β表达量明显升高,雌二醇、雌激素受体相关受体α、SRY相关蛋白9、Ⅱ型胶原的α1链表达量明显降低(P < 0.05);与模型组比较,实验组白细胞介素1β表达量明显降低(P < 0.05),雌二醇、雌激素受体相关受体α、SRY相关蛋白9、Ⅱ型胶原的α1链表达量明显升高(P < 0.05);与阳性对照组比较,实验组白细胞介素1β、雌激素受体相关受体α及Ⅱ型胶原的α1链表达量明显升高(P < 0.05),SRY相关蛋白9表达量明显降低(P < 0.05)。实验结果表明,IL-1β/ERRα/SOX9/Col2α1信号通路参与膝骨关节炎软骨病变,补肾健脾活血中药可通过该机制发挥治疗作用。

Abstract:

BACKGROUND: Knee osteoarthritis is the most common degenerative joint disease with high morbidity and disability, which severely threatens the life quality of patients. Chinese herbs that invigorate the kidney and spleen and activate blood circulation can improve the clinical symptoms of knee osteoarthritis, but its specific mechanism is still unclear.

OBJECTIVE: To study the mechanism of invigorating kidney, invigorating spleen and activating blood circulation herbs regulating the IL-1β/ERRα/SOX9/Col2α1 signaling pathway in the treatment of knee osteoarthritis in ovariectomized rats.

METHODS: Six-month-old female Sprague-Dawley rats were randomly divided into blank control group, model group, experimental group and positive control group. The ovariectomy and excision of the cruciate ligament and medial meniscus were performed in the latter three groups to make the rat models of knee osteoarthritis. Two weeks after operation, the rats were treated with invigorating kidney, invigorating spleen and activating blood circulation herbs, celecoxib capsules, or normal saline. Serum samples and knee cartilage tissues were collected after 6 weeks of continuous gastric administration. Serum estradiol content was detected by ELISA. Expression of IL-1β/ERRα/SOX9/Col2α1 signaling pathway in articular cartilage tissues was detected by fluorescence quantitative PCR and western blot.

RESULTS AND CONCLUSION: Compared with the blank control group, the expression of IL-1β in the model group increased significantly, while the expression of estradiol, ERRα, SOX9 and Col2α1 decreased significantly (P < 0.05). Compared with the model group, the expression of IL-1β in the experimental group decreased significantly, while the expression of estradiol, ERRα, SOX9 and Col2α1 increased significantly (P < 0.05). Compared with the positive control group, the expression of IL-1β, ERRα, and Col2α1 in the experimental group was significantly increased, while the expression of SOX9 decreased significantly (P < 0.05). These results indicate that the IL-1β/ERRα/SOX9/Col2α1 signaling pathway is involved in knee osteoarthritis-induced cartilage lesion, and Chinese herbs for invigorating kidney and spleen and activating blood circulation play a therapeutic role through this mechanism.
