Abstract:
BACKGROUND:Discogenic pain is a major cause of chronic low back pain,and its inflammation mechanism that is participated by many cytokines is well known by more and more people. However,what is the role of these cytokines in the occurrence and development of pain and how we use them to control pain are still not consistent. OBJECTIVE:To completely learn about the pathogenesis of intervertebral disk herniation,the relative cytokines in the occurrence and development of pain and the advances in the treatment of chronic pain with cytokines. RETRIEVE STRATEGY:A computer-based online search of CNKD was undertaken to identify the relevant articles dated from January 1994 to June 2007 with the Chinese of "cytokine,pain". And totally 153 articles were collected. Meanwhile,PubMed database was searched for English articles published from January 2002 to June 2007 with the keywords of "gene,chronic pain" and 36 were collected. The articles that involved the basic and clinical researches closely related with cytokine were selected. Repetitive articles were excluded. After the trail,6 Chinese and 24 English articles were involved. LITERATURE EVALUATION:Of the 30 articles,10 were focused on the basic research and animal experiment,and 20 were about clinical research. There were 7 of RCT,1 of EBM review,10 of summary analysis,2 of case report,and 10 of experience exchange. DATA SYNTHESIS:The mechanisms of discogenic pain include inflammation and immune ones besides mechanical pressure. Inflammation mechanism of discogenic pain is well known by more and more people,in which many cytokines such as substance P,phospholipase A2,tumor necrosis factor,interleukin,growth factor and NO participate. Meanwhile,the role of immunities should not be ignored. Some researchers have used some cytokines(interleukin 1 receptor antagonist,vascular endothelial growth factor,etc) in clinic to treat pains and got good effect. CONCLUSION:The mechanism of pain and various effects of pain-killer are based on gene. Cytokines play important roles in the occurrence,development and treatment of discogenic pain.
