摘要:

文题释义:
内热针疗法:是软组织外科学创始人宣蛰人教授经过临床应用总结出的一种最新软组织疼痛治疗方式,以软组织外科学无菌性炎症致痛学说为理论依据,通过针刺效应和热效应松解病变肌筋膜的激痛点,解除肌肉组织痉挛,达到局部组织的减压及减张,改善局部供血,消除无菌性炎症,松解局部肌肉痉挛,调节生物力学平衡,以达到治疗疾病的目的。
骨保护素:是作为肿瘤坏死因子的家族成员,可以调节破骨细胞和骨吸收过程,骨保护素是核因子κB受体活化因子配体(RANKL)的可溶性诱饵受体,与核因子κB受体活化因子(RANK)竞争性结合,可抑制RANKL与RANK的结合,从而抑制破骨细胞的形成和活性,在骨重塑过程中发挥重要作用。

背景:出于疾病治疗目的,临床上糖皮质激素被广泛应用,导致该类患者群体患激素性股骨头缺血性坏死的风险增加。然而目前为止,激素性股骨头缺血性坏死的详细发病机制尚不明确。内热针疗法治疗激素性股骨头缺血性坏死在临床上效果良好,但对其具体作用机制尚未明晰。
目的:探讨内热针疗法对激素性股骨头缺血性坏死股骨头组织中骨保护素、核因子κB受体活化因子配体(receptor activator of nuclear factor kappa B ligand,RANKL)表达的影响。
方法:随机在30只健康、无特定病原体的SD大鼠中选择10只作为空白组,其余20只采用甲基强的松龙联合大肠杆菌内毒素的方法制备激素性股骨头缺血性坏死模型,造模成功后再随机分为模型对照组和治疗组,每组10只。治疗组对SD大鼠双侧臀部进行1次/周的内热针治疗,20 min/次,设定温度为42 ℃;空白组和模型对照组均不采取任何处理。干预前后对大鼠进行一般状态和行为学检测实验(测定自主活动次数和抓力);干预4周后对大鼠双侧股骨头取材,采用苏木精-伊红染色观察各组大鼠股骨头骨组织形态学变化并计算空骨陷窝率;分别采用实时荧光定量PCR、免疫组织化学染色和蛋白免疫印迹法检测各组股骨头组织中骨保护素、RANKL的mRNA及蛋白表达。
结果与结论:①与空白组相比,模型对照组和治疗组大鼠的相关行为学评分明显降低(P < 0.01);干预后与模型对照组相比,治疗组大鼠的相关行为学评分升高(P < 0.05);②与空白组相比,模型对照组的股骨头组织形态学明显恶化且空骨陷窝率升高(P < 0.001),差异有显著性意义;干预后与模型对照组相比,治疗组的股骨头组织形态学明显改善且空骨陷窝率降低(P < 0.05);③与空白组相比,模型对照组大鼠股骨头组织中的RANKL的蛋白及mRNA表达水平明显升高,骨保护素的蛋白及mRNA表达水平明显降低,差异均有显著性意义(P < 0.001);干预后与模型对照组相比,治疗组大鼠股骨头组织中的RANKL的蛋白及mRNA表达水平明显降低,骨保护素的蛋白及mRNA表达水平明显升高,差异均有显著性意义(P < 0.05);④结果说明,内热针疗法可能通过上调骨保护素的表达和下调RANKL的表达,抑制破骨细胞的功能及活性,从而抑制骨吸收,促进新骨的形成及骨组织修复。

Abstract: BACKGROUND: For the therapeutic purpose, glucocorticoids have been widely used in clinic, resulting in an increased risk of steroid-induced avascular necrosis of the femoral head (SANFH). However, the detailed pathogenesis of SANFH is not yet clear. Internal heat-type acupuncture therapy has a good clinical effect in the treatment of SANFH, but its specific mechanism has not been clearly analyzed.
OBJECTIVE: To explore the effect of internal heat-type acupuncture on the expression of osteoprotegerin and nuclear factor kappa B receptor activator ligand (RANKL) in SANFH femoral head tissue.
METHODS: Thirty healthy Sprague-Dawley rats without specific pathogens were randomly divided into blank group (n=10) and model group (n=20). The SANFH model was made by methylprednisolone combined with Escherichia coli endotoxin. After successful modeling, the model rats were further randomly divided into model group (n=10) and treatment group (n=10). In the treatment group, the bilateral buttocks of Sprague-Dawley rats were treated with internal heat-type acupuncture once a week for 20 minutes, and the temperature was set at 42 °C. Both the blank group and the model group were not given any treatment. The general state and behaviors (number of voluntary activities and holding power) of Sprague-Dawley rats were detected before and after intervention, and the bilateral femoral heads of rats were taken after 4 weeks of intervention. The histomorphological changes of the rat femoral head were observed by hematoxylin-eosin staining and the rate of empty lacunae was calculated. The mRNA and protein expressions of osteoprotegerin and RANKL in the femoral head tissues of each group were detected by real-time fluorescence quantitative PCR, immunohistochemical staining and western blot, respectively.
RESULTS AND CONCLUSION: The behavioral scores of rats in the model and treatment groups were significantly lower than those in the blank group (P < 0.01). After intervention, the behavioral scores of rats in the treatment group were significantly higher than those in the model group. Compared with the blank group, the histomorphology of the femur became significantly worse and the rate of empty bone lacuna was significantly higher in the model group (P < 0.001). Compared with the model group, the histomorphology of the femur was significantly improved and the rate of empty bone lacuna was decreased in the treatment group (P < 0.05). Compared with the blank group, the expression levels of RANKL protein and mRNA in the rat femoral head tissue were significantly higher in the model group, while the protein and mRNA expression levels of osteoprotegerin were significantly lower in the model group (P < 0.001). After intervention, the expression levels of RANKL protein and mRNA in the rat femoral head tissue in the treatment group were significantly lower than those in the model group, while the protein and mRNA expression levels of osteoprotegerin were significantly higher than those in the model group (P < 0.05). To conclude, internal heat-type acupuncture may up-regulate the expression of osteoprotegerin, down-regulate the expression of RANKL, and inhibit the function and activity of osteoclasts, thus inhibiting bone resorption and promoting new bone formation and bone tissue repair.
