ABSTRACT
Objective: To observe the short-term and long-term clinical effect of modified Wufu Maxin Guijiang decoction treatment to chronic nonspecific low back pain (NLBP) with syndrome of cold dampness and stasis, and to investigate the mechanism of anti-inflammatory and analgesia. Method: One hundred and nineteen eligible patients were randomly divided into control group (59 cases) and observation group (60 cases) by random number table. Patients in control group got acupuncture treatment and pilates. Based on the treatment in control group, patients in observation received additional modified Wufu Maxin Guijiang decoction, 1 dose/day. The course of treatment was 6 weeks in both groups. Before and after treatment, scores of short-form McGill pain questionnaire (SF-MPQ), Oswestry disability index (ODI), Japanese orthopaedic association (JOA) and syndrome of cold dampness were graded. After treatment, the patients made self efficacy assessment. Levels of thromboxane 2 (TXB2), 6-Keto-PGFla, tumor necrosis factor-α(TNF-α) and interleukins-1β(IL-1β) were detected both before and after treatment. Result: After treatment, the rank sum test showed that the clinical efficacy in observation group was better than that in control group (Z=2.226, PZ=2.104, PPP2, TNF-α and IL-1β and TXB2/6-Keto-PGFla were lower than those in control group (Pla was higher than that in control group (PConclusion: Based on the acupuncture treatment and pilates, modified Wufu Maxin Guijiang decoction in the treatment of chronic NLBP can ameliorate symptoms of pain, promote the recovery of function, and enhance activity of daily living in a short term, reduce the recurrence and stabilize the disease condition in a long term, with certain effects of anti-inflammatory and analgesia.
