文题释义:
转化生长因子β1:是一族多肽生长因子,广泛分布于骨骼及神经系统中,可加速成骨母细胞的激活与分化,抑制破骨细胞的活化和骨间充质干细胞向脂肪细胞分化,调节血管平滑肌细胞的分化和骨折断端新生血管形成,促进成骨细胞合成Ⅰ型胶原、骨连接蛋白和骨连接素等,加快新生骨基质的合成和堆积。骨折愈合早期及中期,主要由血小板释放转化生长因子β1,以启动及维持骨折修复过程;软骨形成期及以后,则由间充质细胞和未分化的软骨细胞等自身修复细胞产生转化生长因子β1,促进骨折愈合。
少阳生骨方的功效:基于《黄帝内经》中“少阳主骨”理论的少阳生骨方以小柴胡汤为基础加味而成,原为少阳证而立,但后世医家对其功效进行了广泛的扩展。方中柴胡配黄芩,清泻胆热,透邪解郁,和解少阳;半夏配生姜,降泻浊气,辛升宣散,制黄芩苦寒伤胃;党参、大枣、甘草益气扶正;山茱萸、骨碎补、怀牛膝补肾壮阳,强筋健骨。诸药配伍,则该方可和解少阳、疏利经脉、调和阴阳。
摘要
背景:
少阳生骨方在促进软骨修复方面效果明显,但对促进骨折愈合方面的作用尚不明确。转化生长因子β1可抑制破骨细胞的活性,刺激成骨细胞的活化,加速骨基质的合成与积累,可在一定程度上反映骨折愈合的速度。
目的:探讨少阳生骨方对SD大鼠骨折愈合的影响及作用机制。
方法:取72只SD大鼠进行左侧胫骨骨折造模,造模后随机等分为少阳生骨方组,骨肽片组和对照组。于造模后7,15,30及56 d每组分别随机选取6只大鼠,对患肢行X射线检查,称取患肢胫骨湿质量, ELISA法和免疫组化检测血清及骨折部分转化生长因子β1的表达。
结果与结论:①X射线片显示:少阳生骨方组和骨肽片组骨断端连续骨痂形成数量比对照组明显较多,骨痂密度较高,骨折线模糊;骨断端愈合程度明显优于对照组;②胫骨湿质量:少阳生骨方组胫骨湿质量随着时间的推移逐渐增加,但与骨肽片组差异无显著性意义(P > 0.05)。但少阳生骨方组和骨肽片组胫骨湿质量明显高于对照组(P < 0.05);③血清转化生长因子β1:造模后第7天,3组血清转化生长因子β1水平无明显差异(P > 0.05);造模后15,30及56 d,少阳生骨方组和骨肽片组转化生长因子β1水平明显高于对照组(P < 0.05);④骨折部分转化生长因子β1:少阳生骨方组和骨肽片组相比差异无显著性意义(P > 0.05),少阳生骨方组和骨肽片组均明显优于对照组(P < 0.05);⑤结果表明,少阳生骨方能够促进大鼠血清及骨折部分转化生长因子β1的表达,促进SD大鼠胫骨骨折断端骨痂形成,加速骨愈合。

Abstract:

BACKGROUND: Shaoyang Shenggu formula has been shown to significantly promote cartilage repair, but its effect on fracture healing is unclear. Transforming growth factor β1 (TGF-β1) can inhibit the activity of osteoclasts, stimulate the activation of osteoblasts, accelerate the synthesis and accumulation of bone matrix, and reflect the speed of fracture healing to a certain extent.
OBJECTIVE: To explore the effect of Shaoyang Shenggu formula on the fracture healing in rats and the underlying mechanism.
METHODS: Seventy-two Sprague-Dawley rats were subjected to left tibial fracture modeling, and then equivalently randomized into Shaoyang Shenggu, Ossotide and control groups. At 7, 15, 30 and 56 days after modeling, six rats from each group were selected for X-ray examination. The wet weight of the broken tibia was measured. The serum level of TGF-β1 was tested by ELISA, and the expression level of TGF-β1 in the bone stump was detected by immunohistochemistry.
RESULTS AND CONCLUSION: The X-ray examination revealed that in the Shaoyang Shenggu and Ossotide groups, the amount of callus formation in the bone stump was significantly higher than that in the control group, and the density of callus was higher, and the line of fracture was indistinct. The fracture healing degree in the Shaoyang Shenggu and Ossotide groups was obviously better than that in the control group. The tibial wet weight in the Shaoyang Shenggu group was gradually increased over time but no significant difference was observed as compared with the Ossotide group (P > 0.05). The wet weight of tibia in the Shaoyang Shenggu and Ossotide groups was significantly higher than that in the control group (P < 0.05). At 7 days after modeling, there was no significant difference in the serum level of TGF-β1 among groups (P > 0.05). At 15, 30 and 56 days after injury, the serum level of TGF-β1 in the Shaoyang Shenggu and Ossotide groups was significantly higher than that in the control group (P < 0.05). The expression level of TGF-β1 in the bone stump did not differ significantly between Shaoyang Shenggu and Ossotide groups (P > 0.05), but the level in the Shaoyang Shenggu and Ossotide groups was significantly higher than that in the control group (P < 0.05). These findings suggest that Shaoyang Shenggu formula can increase the expression level of TGF-β1 in the rat serum and bone stump, promote the formation of callus in the tibial lesions, and accelerate bone healing.
