摘要:

背景:骨质疏松对骨折愈合早期的影响尚存争议,仙灵骨葆对骨质疏松性骨折愈合的影响及其机制尚有待深入研究。
目的:观察骨质疏松对大鼠股骨干骨折愈合的影响,以及仙灵骨葆对骨质疏松性骨折愈合的作用。
方法:将50只雌性12周龄Sprague-Dawley大鼠随机分成5组:假手术组、骨折组、去卵巢组、去卵巢+骨折组及治疗组,后3组切除大鼠双侧卵巢制备去卵巢模型,骨折模型于去卵巢后4周制备,为股骨干中段横行骨折。治疗组在去卵巢及骨折基础上灌胃给予仙灵骨葆250 mg/(kg•d)。给药3周,取去卵巢+骨折组、骨折组和治疗组大鼠骨折侧标本行X射线摄像仪摄片后,测量其骨密度,苏木精-伊红染色观察骨痂组织的病理学改变并计数血管,免疫组织化学染色检测骨痂组织骨形态发生蛋白2的表达。
结果与结论:去卵巢处理后大鼠的骨密度、计算机X射线摄像仪摄片评分显著降低(P < 0.05),仙灵骨葆可在一定程度上提高去卵巢后骨折大鼠的骨密度及X射线摄像仪摄片评分,但差异无显著性意义(P > 0.05);仙灵骨葆可提高去卵巢后骨折大鼠骨痂组织的血管数量(P < 0.05),但对骨形态发生蛋白2的表达无影响。提示,去卵巢后大鼠骨折早期愈合过程延迟,仙灵骨葆可促进骨质疏松大鼠骨折愈合早期血管的形成。

Abstract:

BACKGROUND: Controversy still exists in impact of osteoporosis on early process of fracture healing, and the effect and related mechanism underlying Xianlinggubao (XLGB) on osteoporotic fracture healing need further study.
OBJECTIVE: To confirm the influence of osteoporosis on the healing of femoral shaft fracture and to investigate the effects of XLGB on osteoporotic fracture healing.
METHODS: Fifty female 12-week old Sprague-Dawley rats were randomly divided into 5 groups with 10 animals in each group: sham-surgery, fracture, ovariectomy (OVX), OVX + fracture and XLGB. OVX was performed in bilateral sides of rats. Transverse fracture model of femoral shaft was established at 4 weeks after OVX. Rats in XLGB treatment group were treated with 250 mg/kg XLGB daily for 3 weeks following the establishment of OVX and fracture. Rats in the OVX + fracture, fracture and XLGB treatment groups were harvested the femoral fracture samples for bone mineral density test by X-ray radiography. The pathological changes of callus tissues were detected with hematoxylin-eosin staining and blood vessels were counted. Immunohistochemical staining was applied to determine the expression of bone morphogenetic protein 2 in callus tissues.
RESULTS AND CONCLUSION: Bone mineral density test and computed X-ray radiography score showed a significantly reduction in the rats following OVX (P < 0.05). XLGB treatment could enhance the bone mineral density and X-ray radiography score in the OVX and fracture rats, with no significant difference (P > 0.05). XLGB treatment also increased the quantity of callus tissues compared with OVX + fracture and fracture groups (P < 0.05). No significant difference was observed of bone morphogenetic protein-2 expression among three groups. The ovariectomized rats show a delayed fracture healing process and XLGB could promote the early vascular formation of osteoporotic fracture healing.
