Changes of Serum Cytokines in Patients with Lumbar Intervertebral Disc Herniation and Pain / 现代检验医学杂志

ABSTRACT

Objective To study the relationship between the pain of the patients with lumbar intervertebral disc herniation (LIDH) and the changes of serum cytokine,and to discuss the clinical significance.Methods From January 2014 to December 2016,74 cases of LIDH diagnosed in the 323rd Hospital of the PLA were selected,including 45 males and 29 females,whose age was 46.2± 16.1 years,and the duration 22.6± 7.8 months.According to the VAS pain score,37 cases were mild,23 cases were moderate and 14 cases were severe.The control was 30 cases of healthy physical examination in the same period,18 males and 12 females,age 45.3 ± 15.8 years.All subjects were collected for venous blood on fasting.MDA,superoxide dismutase (SOD),interleukin-6 (IL-6),tumor necrosis factor (TNF),thromboxane (TX),endothelin (ET),prostaglandin E (PGE) and calcitonin (CA) were all measured by radioimmunoassay.The results were analyzed statistically.Results The compared with normal control group,serum cytokines MDA,SOD,IL-6,TNF,TX,ET,PGE and CA increased in different degrees (P＜0.05～0.01).The VAS assessment of severe pain in LIDH was significantly higher than that of mod erate or mild pain (P＜0.05～0.01).Logistic analysis showed that these serum cytokines were closely related to the pain of LIDH (OR=2.415～4.127,95％CI=1.146～11.735,P＜0.05).Conclusion The serum cytokines in patients with LIDH are closely related to the degree of pain,suggesting that these cytokines in serum may affect biochemical metabolism in the process of pain.
