To evaluate intervertebral disc levels of inflammatory factor (interleukin 6) and proteinase activity (cathepsin B) in patients with a degenerative disease and serum levels of interleukin 6, serum cathepsin B activity and hyaluronic acid biomarkers.
We conducted immunohistochemistry studies of intervertebral discs to analyze interleukin 6 and cathepsin B levels of patients with degenerative disease and spine fracture (Control Group) and to measure hyaluronic acid, interleukin 6 and cathepsin B activity from sera of intervertebral disc degeneration patients, fracture patients, and healthy individuals.
Interleukin 6 and cathepsin B seem to be related with physiopathology of intervertebral disc degeneration, since the levels of both were higher in discs of patients with intervertebral disc degeneration. Interleukin 6 and cathepsin B do not represent good biomarkers of degenerative intervertebral disc disease, since the level of such compounds is increased in the plasma of patients with fractures.
Hyaluronic acid can be a biomarker for intervertebral disc degeneration, because hyaluronic acid levels were higher only in sera of patients with intervertebral disc degeneration.
评估患有退行性疾病患者椎间盘炎症因子（白细胞介素6）水平和蛋白酶活性（组织蛋白酶B），以及血清白细胞介素6水平、血清组织蛋白酶B活性和透明质酸生物标志物。
我们对椎间盘进行免疫组织化学研究，以分析患有退行性疾病和脊柱骨折患者（对照组）的白细胞介素6和组织蛋白酶B水平，并测量椎间盘退变患者、骨折患者和健康个体血清中的透明质酸、白细胞介素6和组织蛋白酶B活性。
白细胞介素6和组织蛋白酶B似乎与椎间盘退变的病理生理学相关，因为在椎间盘退变患者的椎间盘中二者水平均较高。白细胞介素6和组织蛋白酶B并非退行性椎间盘疾病的良好生物标志物，因为此类化合物水平在骨折患者血浆中也会升高。
透明质酸可以作为椎间盘退变的生物标志物,因为仅在椎间盘退变患者的血清中透明质酸水平较高。
