目的:建立左股骨中段闭合折骨经皮髓内克氏针固定的标准骨折模型,观察丹参接骨胶囊对SD大鼠骨折愈合过程中局部转化生长因子β1(transforming growth factor beta 1,TGF-β1)mRNA、蛋白表达,通过RT-PCR,ELISA法进行分析转化生长因子β1的表达,探讨丹参接骨胶囊对大鼠骨折愈合的机制。方法:建立闭合性的股骨干骨折髓内固定模型,分别给与相应药物灌胃治疗,在不同时相通过RT-PCR,ELISA法进行分析TGF-β1 mRNA及蛋白表达。结果:丹参接骨胶囊能促进骨折SD大鼠TGF-β1 mRNA及蛋白的表达。结论:大鼠股骨中段闭合折骨髓内克氏针固定骨折模型稳定,可操作性强,重复性好。丹参接骨胶囊能促进骨折SD大鼠TGF-β1 mRNA及蛋白的表达。 相似文献

BACKGROUND: Salvia miltiorrhiza bone-setting capsule is a traditional Chinese medicine for the treatment of fractures due to activating blood circulation to dissipate blood stasis, reducing swelling and pain.
OBJECTIVE: To observe the effects of Salvia miltiorrhiza bone-setting capsule on the fracture healing in a rat model of closed femoral fractures.
METHODS: Rats were randomly divided into salvia miltiorrhiza bone-setting capsule group, physiological saline group and normal group. In the salvia miltiorrhiza bone-setting capsule group and physiological saline group, rat models of closed femoral fractures were prepared, and then given physiological saline and salvia miltiorrhiza bone-setting capsule 2 pills by intragastric administration. In the normal group, rats were housed normally. At 7, 14 and 28 days after fractures, hematoxylin-eosin staining conditions, serum osteocalcin, the expression of collagen type I, and the expression of protein and mRNA callus transforming growth factor-beta 1 were observed in the salvia miltiorrhiza bone-setting capsule group and physiological saline group.
RESULTS AND CONCLUSION: (1) Hematoxylin-eosin staining demonstrated that at 7 days after fractures, no significant difference was found in pathological changes of femoral fracture in salvia miltiorrhiza bone-setting capsule group and physiological saline group. At 14 and 28 days after fractures, pathological repair was more obvious in the salvia miltiorrhiza bone-setting capsule group than in the physiological saline group. (2) At 3 and 7 days after fractures, serum osteocalcin and the expression of type I collagen were significantly increased in the salvia miltiorrhiza bone-setting capsule group and physiological saline group (P < 0.05), and the expression trend was consistent in both groups. The expression was always higher in the salvia miltiorrhiza bone-setting capsule group than in the physiological saline group, and significant differences were found at 14 and 28 days after fractures (P < 0.01). (3) Transforming growth factor beta 1 expression reached a peak at 3 days after fractures, gradually reduced, increased at 14 days (the second peak), and diminished at 28 days in the salvia miltiorrhiza bone-setting capsule group and physiological saline group. The expression trend of transforming growth factor beta 1 was consistent in the salvia miltiorrhiza bone-setting capsule group and physiological saline group. At 7, 14 and 28 days, the transforming growth factor beta 1 expression was higher in the salvia miltiorrhiza bone-setting capsule group than in the physiological saline group. (4) Results showed that salvia miltiorrhiza bone-setting capsule could promote fracture healing, and its mechanism was probably associated with serum osteocalcin, the expression of collagen type I and transforming growth factor-β1.
