摘要:


文题释义:

额尔敦-乌日勒:由29味药物配合而组成的蒙药,其方中含有藏红花、草果、柯子、牛黄,麝香、草决明、珍珠等,具有扩张毛细血管、改善微循环、抑制血小板聚集和抗血栓等作用,临床上主要用于防治黑、白脉病以及中风、痛风、痹病和全身拘挛等病。

激素性股骨头坏死:是一种类固醇治疗引起的双侧股骨头坏死并发症,致残率高。激素性股骨头坏死的发病机制复杂、多样。长期使用糖皮质激素药物导致股骨头血供受损,骨细胞和骨髓细胞死亡,进而导致结构改变、股骨头塌陷和关节功能障碍。


背景:激素性股骨头坏死是一种类固醇治疗引起的双侧股骨头坏死并发症,致残率高,然而临床治疗效果并不显著。额尔敦-乌日勒是珍贵蒙药方剂,主要用于防治骨关节疾病,但其改善激素性股骨头坏死的作用机制尚不清楚。
目的:研究蒙药额尔敦-乌日勒(Erden-uril,EU)对激素性股骨头坏死药效作用机制。
方法:将50只大鼠随机分成正常组、股骨头坏死组、低剂量EU组(灌胃0.1 g/kg的蒙药额尔敦-乌日勒)、高剂量EU组(灌胃0.4 g/kg的蒙药额尔敦-乌日勒)和阿仑膦酸钠组(灌胃阳性药阿仑膦酸钠片水溶液)。除正常组外,其余各组大鼠腹腔联合臀肌分别注射脂多糖(10 μg/kg)和甲泼尼松龙(20 mg/kg)建立激素性股骨头坏死模型;灌胃药物1次/d,共6周。6周后,采用苏木精-伊红染色法评估股骨头坏死模型;Tunel法检测各组股骨头组织中细胞凋亡情况;ELISA和免疫组化法检测各组股骨头组织中促凋亡蛋白Bax和抑凋亡蛋白Bcl-2的表达水平;Western blot法检测各组股骨头组织中ATG5、Beclin-1、LC3II、Caspase-3、Bax和Bcl-2的蛋白表达情况。

结果与结论:①与正常组相比较,股骨头坏死组大鼠股骨头组织空骨陷窝数量增多,且脂肪细胞增大、增多;Bax表达量显著增加,ATG5、Beclin-1、LC3II和Bcl-2表达量显著降低。与股骨头坏死组相比,蒙药额尔敦-乌日勒处理后大鼠空骨陷窝、脂肪细胞均显著减小,脂肪细胞减少,骨髓细胞显著增多;凋亡细胞数显著减少;与股骨头坏死组相比,除Western blot法表明低剂量额尔敦-乌日勒显著上调Bax表达外,其他方法均表明低、高剂量额尔敦-乌日勒显著下调Bax和Caspase-3表达量,显著上调ATG5、Beclin-1、LC3II和Bcl-2表达量;低、高剂量组间蛋白表达差异无显著性意义。②结论:蒙药额尔敦-乌日勒可能通过促进细胞自噬发挥抗凋亡作用保护脂多糖联合甲泼尼松龙引起的大鼠股骨头坏死。

Abstract: BACKGROUND: Steroid-induced avascular necrosis of the femoral head is a complication of bilateral osteonecrosis of the femoral head caused by steroid treatment with a high disability rate, but the therapeutic effect is not significant. Erden-uril is a precious Mongolian medicine prescription, mainly used to prevent and treat bone and joint diseases, but its mechanism of improving steroid-induced avascular necrosis of the femoral head is still unclear.
OBJECTIVE: To study the action mechanism of Mongolian Medicine Erden-uril on steroid-induced avascular necrosis of the femoral head in rat.
METHODS: Fifty rats were randomly divided into normal group, model group, low-dose Erden-uril group (0.1 g/kg Erden-uril by gavage), high-dose Erden-uril group (0.4 g/kg Erden-uril by gavage) and alendronate sodium group. Except for the normal group, rats in the other groups were intraperitoneally injected with 10 μg/kg lipopolysaccharide and 20 mg/kg methylprednisolone to establish animal models of steroid-induced avascular necrosis of the femoral head. Administration by gavage in each group was performed once a day for 6 weeks. Subsequently, hematoxylin-eosin staining was used to evaluate the femoral head necrosis model; TUNEL method was used to detect apoptosis in femoral head tissue; ELISA and immunohistochemistry were used to detect the expression levels of pro-apoptotic protein Bax and anti-apoptotic protein Bcl-2 in femoral head tissue; and western blot method was used to detect the protein expression of ATG5, Beclin-1, LC3II, Caspase-3, Bax and Bcl-2 in femoral head tissue.
RESULTS AND CONCLUSION: Compared with the normal group, the number of empty bone lacunae was significantly increased, and adipocytes were enlarged and increased in the model group; the expression of Bax increased significantly and that of ATG5, Beclin-1, LC3II and Bcl-2 decreased significantly in the model group. Compared with the model group, treatment with Mongolian medicine Erdun-uril could significantly reduce the number of empty bone lacunae and the amount of adipocytes, significantly increase the number of bone marrow cells, and significantly decrease the number of apoptotic cells. Compared with the model group, all methods showed significant down-regulation of Bax and Caspase-3 expression and significant up-regulation of ATG5, Beclin-1, LC3II and Bcl-2 expression after treatment with low and high doses of Erdun-uril, except for western blot detection, which showed significant up-regulation of Bax expression after treatment with low-dose Erdun-uril. Moreover, there was no significant difference in protein expression between low- and high-dose Erdun-uril groups. To conclude, Erdun-uril may protect avascular necrosis of the femoral head induced by lipopolysaccharide combined with methylprednisolone in rats by promoting autophagy with anti-apoptotic effects. 

Key words: Mongolian medicine, Erdun-uril, steroid-induced avascular necrosis of the femoral head, apoptosis, autophagy
