摘要:

背景:脊柱椎板减压后硬膜外瘢痕是导致继发性椎管狭窄的重要原因之一。研究证实局部应用三七凝胶能有效预防术后硬膜外瘢痕粘连的形成。
目的:进一步验证三七透明质酸钠凝胶在家兔硬膜外瘢痕组织中α-平滑肌肌动蛋白表达的影响。
方法:大耳白品系家兔96只,随机方法分为4组,制作家兔椎板切除模型,分别在兔硬膜囊周围涂抹生理盐水、三七浓缩液、透明质酸钠、三七透明质酸钠凝胶各0.5 mL,用药后1,2,4,8周取材,采用免疫组织化学方法分析α-平滑肌肌动蛋白抗体的表达。
结果与结论:用药1,2周时,与生理盐水组比较,其他3组α-平滑肌肌动蛋白抗体表达明显降低(P < 0.01或P < 0.05),三七透明质酸钠凝胶组与三七组、透明质酸钠组差异不显著(P > 0.05);用药4,8周时,三七透明质酸钠凝胶组α-平滑肌肌动蛋白抗体表达明显低于其他3组(P < 0.01或P < 0.05),三七组、透明质酸钠组与生理盐水组差异不显著(P > 0.05)。结果证实三七透明质酸钠凝胶抑制α-平滑肌肌动蛋白的表达,减轻瘢痕挛缩。

Abstract:

BACKGROUND: Epidural scar after laminectomy is one important reason for the secondary spinal stenosis, and local application of Sanqi sodium hyaluronate gel can prevent epidural scar adhesion after laminectomy.
OBJECTIVE: To study the effects of Sanqi sodium hyaluronate gel on α-smooth muscle actin expression in the process of rabbit’s epidural scar formation.
METHODS: In this study, there were ninety-six rabbits which were randomized into four groups and given 0.5 mL normal saline, 0.5 mL Sanqi concentrated solution, 0.5 mL sodium hyaluronate and 0.5 mL Sanqi sodium hyaluronate gel around the dura. At 1, 2, 4, 8 weeks after treatment, immunohistochemistry staining was employed for analysis of α-smooth muscle actin expression.
RESULTS AND CONCLUSION
: At the end of weeks 1 and 2, the expression of α-smooth muscle actin antibody in the normal saline group was significantly higher than that in the other three groups (P < 0.01 or P < 0.05), but there were no significant differences among the Sanqi, sodium hyaluronate and Sanqi sodium hyaluronate gel groups (P > 0.05). At weeks 4 and 8, the expression of α-smooth muscle actin antibody in the Sanqi sodium hyaluronate gel group was significantly lower than that in the other three groups (P < 0.01 or P < 0.05), and there was no significant difference among the latter three groups (P > 0.05). These findings suggest that Sanqi sodium hyaluronate gel can inhibit the expression of α-smooth muscle actin, and thus ease scar contracture.
