疝出型和退變突出型腰椎間盤組織中白細胞介素-17表達及與Modic改變的病理機制
[Abstract]:Objective to investigate the expression of interleukin-17 (IL) 17) in herniated and degenerative lumbar intervertebral disc tissues, and to explore the relationship between Modic changes and herniation type. Methods Sixty-two patients with single segment lumbar disc herniation were divided into injury herniation group (41 cases) and degenerative herniation group (21 cases) according to the type of disc herniation. According to magnetic resonance imaging (MRI), the patients were divided into Modic change group (n = 22) and non-Modic group (n = 40). Intraoperative specimens of intervertebral discs were stained with hematoxylin-eosin (HE) and immunohistochemical, SYBR green quantitative PCR was used to detect the pathological changes and IL-17 expression of intervertebral discs. Results the incidence of neovascularization in the hernia injury group was significantly higher than that in the degenerative herniation group (P 0.01). The number of IL-17 positive cells in degenerative herniation group was significantly lower than that in injured hernia group (P0.01). The expression of IL-17 mRNA in the injured hernia group was significantly higher than that in the degenerative herniation group (P0.01). Modic was significantly higher than that in the non-Modic change group (P0.01). There was a significant correlation between the expression of IL-17 mRNA in hernia type and the change of Modic (P 0.001). Conclusion there is a significant local inflammatory response in the nucleus pulposus of the injured herniated lumbar intervertebral disc and the expression of IL-17 in the injured herniated disc suggests that it mediates the changes of immune inflammation in the microenvironment of the nerve root of the intervertebral disc. Autoimmune response is involved in the pathological mechanism of Modic changes.
