摘要:

背景:胶原纤维是维持椎间盘正常结构与功能的重要物质,椎间盘中胶原的类型及含量的变化,影响整个椎间盘的生理和病理状态,Ⅰ型及Ⅱ型胶原是椎间盘胶原的主要组分。
目的:观察六味地黄丸含药血清对肿瘤坏死因子α致伤兔椎间盘Ⅰ型、Ⅱ型胶原蛋白和基因表达的影响。
方法:将15只新西兰白兔带终板的45个L2-L5椎间盘随机分为空白第1天组、空白第14天组、肿瘤坏死因子α组、中药血清组、肿瘤坏死因子α+中药血清组。后两种培养液中分别含5 μg/L肿瘤坏死因子α和体积分数10%六味地黄丸血清,培养14 d后收集髓核和纤维环观察。
结果与结论:RT-PCR和Western Blot检测结果表明,随着培养时间的延长,纤维环中Ⅰ型胶原及髓核中Ⅱ型胶原蛋白和基因表达明显降低;加入肿瘤坏死因子α可加速这种变化,而含药血清可延缓Ⅰ,Ⅱ型胶原蛋白和基因表达变化。提示六味地黄丸可通过稳定Ⅰ,Ⅱ型胶原蛋白和基因表达,对椎间盘细胞外基质具有保护作用。

Abstract:

BACKGROUND: Collagen fiber is the main subject to maintain the structural integrity and its physiological function, the type and content of the collagen in intervertebral disc will influence the physical and pathological condition of entire intervertebral disc. Type Ⅰ and type Ⅱcollagen are the main components of intervertebral disc collagen fiber.
OBJECTIVE: To observe the effect of Liuwei Dihuang Wan-containing serum on expression of type Ⅰ and type Ⅱ collagen and genes of the intervertebral discs in tumor necrosis factor-α injured rabbit.
METHODS: Forty-five L2-L5 intervertebral discs harvested from 15 rabbits were randomly divided into five groups: control 1st day, control 14th day, tumor necrosis factor-α group, Liuwei Dihuang Wan-containing serum group and tumor necrosis factor-α+ Liuwei Dihuang Wan-containing serum group. The culture medium in the Liuwei Dihuang Wan-containing serum group and tumor necrosis factor-α+ Liuwei Dihuang Wan-containing serum group contained
5 μg/L tumor necrosis factor-α and 10% Liuwei Dihuang Wan-containing serum. The nucleus pulposus and annulus fibrosus were collected after cultured for 14 days.
RESULTS AND CONCLUSION: Reverse transcription-PCR and Western Blot showed that with the culture time prolonging, the expressions of type Ⅰ collagen and genes in nucleus pulposus and type Ⅱ collage and genes in the annulus fibrosus were significantly decreased; Tumor necrosis factor-α could aggravate the change, while Liuwei Dihuang Wan-containing serum could delay the changes. The results indicate that Liuwei Dihuang Wan can protect the extracellular matrix of intervertebral discs through stabilizing the expressions of type Ⅰ and type Ⅱ collagen and genes.
