文题释义:
骨折愈合:是指骨折断端间的组织修复反应,这种反应表现为愈合反应,最终是恢复骨的正常结构与正常功能。骨折愈合是一个极其复杂的生物学过程,受诸多因素的影响,最新流行病学调查数据显示约有10%的骨折因各类原因导致骨折愈合延缓甚至无法愈合。

闭合性骨折:闭合性骨折常常伴有软组织损伤。软组织对钝器伤的反应包括微血管反应和炎症性过程,可分为炎症期,增殖期和修复期。闭合性骨折的软组织损伤常采用 Tscherne 分类法,该分类法可被分为C0,CⅠ,CⅡ,CⅢ共4个等级。

 

背景:丹参接骨胶囊是因有显著活血化瘀、消肿止痛的功效而成为治疗骨折的常用中药制剂之一。
目的:观察丹参接骨胶囊对闭合性股骨模型大鼠骨折愈合的影响。
方法:将大鼠随机分为丹参接骨胶囊组、生理盐水组及正常组,丹参接骨胶囊组和生理盐水组制备闭合性股骨骨折模型大鼠,骨折后分别给予生理盐水、丹参接骨胶囊2粒灌胃;正常组正常饲养。观察骨折后7,14,28 d丹参接骨胶囊组及生理盐水组苏木精-伊红染色情况、血清骨钙素、Ⅰ型胶原的表达、骨痂转化生长因子β1蛋白/mRNA的表达。

结果与结论:①苏木精-伊红染色显示,骨折后7 d,丹参接骨胶囊组、生理盐水组骨折组织病理变化无显著差异,骨折后14,28 d丹参接骨胶囊组股骨骨折病理修复较生理盐水组明显。②骨折后3,7 d丹参接骨胶囊组、生理盐水组大鼠血清骨钙素、Ⅰ型胶原的表达均明显升高(P < 0.05),两组表达趋势一致,其中丹参接骨胶囊表达量始终较生理盐水组高,且骨折后14,28 d表达量差异有显著性意义(P < 0.01)。③骨痂转化生长因子β1表达在丹参接骨胶囊组、生理盐水组骨折后第3天出现1个峰值,随后浓度逐渐下降,直至骨折后第14天丹参接骨胶囊组、生理盐水组转化生长因子β1表达又再度升高,出现第2个峰值,至骨折后第28天丹参接骨胶囊组、生理盐水组转化生长因子β1表达浓度再次出现下降。此过程丹参接骨胶囊组、生理盐水组转化生长因子β1表达趋势一致,在7,14,28 d愈合时期,丹参接骨胶囊组大鼠转化生长因子β1表达均高于生理盐水组。④结果证实,丹参接骨胶囊能够促进骨折的愈合,其机制可能与促进血清骨钙素、Ⅰ型胶原及转化生长因子β1的表达有关。

Abstract:

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.
