| 中文摘要: |
| 目的探讨腰椎间盘髓核组织高迁移率族蛋白B2(HMGB2)、淋巴样增强因子-1(LEF-1)、Ⅱ型胶原(Col Ⅱ)mRNA及蛋白表达水平及其临床意义。 方法收集腰椎间盘突出症患者手术摘除的髓核组织标本20例,根据术前腰椎MR片Pfirrmann分级标准均分为轻度退变组和重度退变组。qRT-PCR和Western boltting检测两组髓核组织HMGB2、LEF-1、Col Ⅱ的mRNA及蛋白表达水平,并分析其相关性。 结果与轻度退变组比较,重度退变组HMGB2 mRNA及蛋白、COL Ⅱ mRNA降低(P＜0.05),LEF-1 mRNA升高(P＜0.05)。HMGB2水平与Col Ⅱ水平呈正相关,与LEF-1水平呈负相关(P＜0.05)；LEF-1水平与Col Ⅱ水平呈负相关(P＜0.05)。 结论HMGB2、LEF-1、Col Ⅱ在不同退变程度腰椎间盘髓核组织中表达水平不同,提示其可能与椎间盘退变的发生相关。 |

| To investigate the expression and clinical significance of high mobility group protein B2 (HMGB2), lymphoid enhancer factor-1 (LEF-1) and type Ⅱ collagen (Col Ⅱ) mRAN and protein in nucleus pulposus of degenerative lumbar intervertebral disc. Methods20 specimens of nucleus pulposus from patients with lumbar disc herniation were collected, and divided into mild degeneration group (10 cases) and severe degeneration group (10 cases) according to Pfirmann grading standard of preoperative lumbar MR films. The mRNA and protein expression levels of HMGB2, LEF-1, Col Ⅱ in the lumbar disc nucleus pulposus of the two groups were detected by qRT-PCR and Western blotting, and the correlation between the expression levels was analyzed. ResultsCompared with mild degeneration group, the expression of HMGB2 mRNA and protein, Col Ⅱ mRNA in severe degenerative group decreased (P＜0.05), while the relative expression of LEF-1 mRNA increased (P＜0.05). HMGB2 was positively correlated with Col Ⅱ and negatively correlated with LEF-1(P＜0.05), and LEF-1 was negatively correlated with Col Ⅱ (P＜0.05). ConclusionThe expression levels of HMGB2, LEF-1 and Col Ⅱ in the nucleus pulposus of lumbar intervertebral disc at different degrees of degeneration are different, suggesting that they might be related to the occurrence of intervertebral disc degeneration and predictive indicators of disease progression. |
