To explore the curative effects of Zhiqiao Gancao Decoction combined with lumbar traction in patients with lumbar disc herniation.Methods:A total of 180 patients with lumbar disc herniation admitted to Suzhou Integrated Traditional Chinese and Western Medicine Hospital were randomly divided into a control group(n=88)and a an observation group(n=92).The control group was treated with bed rest，back muscle exercise，lumbar traction for 1 months.The observation group was treated with Zhiqiao Gancao Decoction for 1 months based on the control group.The curative effects of the 2 groups were evaluated and compared.Before and after treatment，Visual analogue pain score(VAS)，lumbar function assessment scale(JOA)score，serum immunoglobulin(Ig)G，Ig M，interleukin-6(IL-6)and tumor necrosis factor-alpha(TNF-α)levels of the 2 groups wer compared.The relationship between immune inflammation indexes with the pain，lumbar function and curative effects of the observation group were analyzed.Results:Compared with those of the control group，after treatment VAS score and serum levels of IL-6，TNF-α，IgG and IgM of the observation group were decreased(P<0.05).Compared with those of before treatment，the VAS score and serum levels ofIL-6，TNF-α，IgG and Ig M in 2 groups decreased，while in the same period JOA score increased(P<0.05).Serum levels of IL-6，TNF-α，IgG and Ig M were positively correlated with VAS score(P<0.05)，while negatively correlated with JOA score and treatment efficiency(P<0.05).Conclusion:Zhiqiao Gancao Decoction combined with lumbar traction can safely and effectively improve the curative effects of lumbar intervertebral disc herniation，and its immune inflammation is related to the curative effects.
