文题释义:
超声透入法:称作超声波法,是指运用超声波促使药物透过完整皮肤而进入软组织的方法。
低频超声促透通络止痛中药:通络止痛中药在低频超声促透特有的空化作用下,可以使通络止痛中药透过皮肤障碍到达患处直达病灶,形成局部浓集和浸润而起到通经活络、消炎止痛的作用。
摘要
背景
:低频超声促透中药复方治疗骨关节炎可有效减轻患者疼痛,改善关节功能,但其作用机制尚不清楚。
目的:观察低频超声促透通络止痛中药对膝骨关节炎模型兔尿激酶型纤溶酶原激活物系统及炎性因子的影响,探讨低频超声促透通络止痛中药的作用机制。
方法:40只新西兰大白兔随机分为4组:正常组、模型组、对照组和实验组。正常组正常饲养,不进行膝骨关节炎造模处理,其余3组均在兔膝关节腔内注入木瓜蛋白酶制作骨关节炎模型,实验组造模后1周给予低频超声促透通络止痛中药治疗,对照组造模后1周给予生理盐水,模型组造模后正常饲养,不进行其他干预。治疗3周后检测血清、关节液中炎性因子水平,对滑膜和关节软骨进行Mankin’s评分,采用Western Blot方法检测关节滑膜中尿激酶型纤溶酶原及其受体蛋白的表达。
结果与结论:①模型组血清、关节液中炎性因子水平与正常组比较明显升高(P < 0.05),实验组血清、关节液内炎性因子水平与模型组比较显著降低(P < 0.05);②实验组滑膜组织Mankin’s评分低于模型组和对照组(P < 0.05),而软骨组织评分与模型组比较差异无显著性意义(P > 0.05);③与模型组比较,实验组关节滑膜尿激酶型纤溶酶原激活物及其受体表达明显降低,尿激酶型纤溶酶原激活物抑制剂表达升高;④结果表明,低频超声促透通络止痛中药可以抑制关节液和血清炎性因子的生成,减轻膝关节局部的炎症反应,进而有效治疗膝骨关节炎。

Abstract:

BACKGROUND: Low-frequency ultrasound combined with Tongluo Zhitong herbs can effectively relieve pain and improve joint function of patients with osteoarthritis, but the underlying mechanisms are still unclear.
OBJECTIVE: To investigate the effects of low-frequency ultrasound combined with Tongluo Zhitong herbs on urokinase-type plasminogen activator (uPA) and inflammatory cytokines of osteoarthritis rabbits and the related mechanisms.
METHODS: Forty rabbits were randomly divided into four groups: normal, model, control, and experimental groups. The normal group was treated with normal feeding, not for any processing. For the other three groups, papain was injected into the rabbit knee articular cavity to establish osteoarthritis models. One week later, the experimental group was treated with low frequency ultrasound combined with Tongluo Zhitong herbs for 3 weeks, the control group treated with the same volume of normal saline, and the model group received no intervention. The levels of inflammatory cytokines in the serum and synovial fluid were measured, the histological changes of synovial tissues and articular cartilage were evaluated using Mankin’s score, and the expression levels of uPA and its receptor were determined by western blot assay.
RESULTS AND CONCLUSION: The levels of inflammatory cytokines in the model group were significantly higher than those in the normal and experimental groups (P < 0.05). The Mankin’s scores of synovial tissue in the experimental group were significantly lower than those in the model and control groups (P < 0.05), while Mankin’s scores of the cartilage tissue had no significant difference between the experimental and model groups (P > 0.05). Compared with the model group, in the experimental group, the expression levels of uPA and its receptor were significantly downregulated, and the expression of uPA inhibitor was notably upregulated. These data show that low-frequency ultrasound combined with Tongluo Zhitong herbs attenuates inflammatory reaction in the synovial tissues, by inhibiting the formation of joint fluid and production of inflammatory cytokines, which is an effective treatment for knee osteoarthritis.
