Abstract:
BACKGROUND:During degeneration of cervical spine, biochemical changes appeared in intervertebral disc cel s. During this process, a variety of inflammatory cytokines may lead to disc herniation, which stimulates the production of a variety of inflammatory factors from surrounding adjacent tissue.
OBJECTIVE:To explore the expression and significance of interleukin-1β, interleukin-6 and cyclooxygenase 2 in patients with different clinical symptoms of cervical spinal cord oppression.
METHODS:Protrusion of the intervertebral disc or disc of responsibility among patients with anterior disc resection and internal fixation were divided into three groups according to clinical symptoms:myelopathic symptom group, nerve root symptom group and cervical spine trauma group. Intervertebral disc received hematoxylin-eosin staining and immunohistochemical staining for morphological observation. Positive cel s were counted according to the result of immunohistochemical staining.
RESULTS AND CONCLUSION:(1) Hematoxylin-eosin staining results showed visible inflammatory cel infiltration and new blood vessel formation in the myelopathic symptom group and nerve root symptom group. No remarkable inflammatory cel infiltration or new blood vessel formation was seen in cervical spine trauma group. (2) Immunohistochemical staining interleukin-1β-, interleukin-6-positive cel s were seen in the myelopathic symptom group. Cytoplasm was stained tan. Cyclooxygenase 2-positive cel s showed a low number. The numbers of interleukin-1β-, interleukin-6-and cyclooxygenase 2-positive cel s were significantly more in the nerve root symptom group than in the myelopathic symptom group. The numbers of interleukin-1β-, interleukin-6-and cyclooxygenase 2-positive cel s were smal in the cervical spine trauma group. (3) Expression rate and IA value of interleukin-1β, expression rate and IA value of interleukin-6 were significantly higher in the myelopathic symptom group and nerve root symptom group than in the cervical spine trauma group (P<0.05). Expression rate and IA value of cyclooxygenase 2 were significantly higher in the nerve root symptom group than in the cervical spine trauma group. (4) These results suggested that interleukin-1β, interleukin-6 and cyclooxygenase 2 expression could be found in the cervical intervertebral disc after protrusion, and played a role in early degeneration of cervical intervertebral disc. The expressions of these inflammatory factors were significantly different in patients with different clinical symptoms of cervical spinal cord compression.
