ABSTRACT
Objective: To observe short-term and long-term efficacies of Danlu Tongdu tablets on lumbar disc herniation (LDH) with kidney deficiency and stasis syndrome, and its effect on nucleus pulposus reabsorption and immunoinflammatory factors. Method: One hundred and sixty patients were randomly divided into control group (80 cases) and observation group by random number table. Patients in control group (80 cases) got acupoint massage and acupuncture, 1 time/day. In addition to the therapy of control group, patients in observation group were also given Danlu Tongdu tablets, 4 tablets/time, 3 times/days. A course of treatment was 12 weeks, and a 9-month follow-up was recorded. Lumbago and leg pain were recorded by visual simulation (VAS) before treatment and at the first, second, third month after treatment. Before and after treatment, Japanese orthopaedic association (JOA), symptoms and signs were scored. During the 9-month follow-up, relapse rate and relapse time were recorded, and VAS and JOA were scored. Absorption of nucleus pulposus was assessed, and levels of interleukin-1 (IL-1), IL-17, tumor necrosis factor-α (TNF-α), matrix metalloproteinases-3 (MMP-3) were detected. Result: By rank sum test, the clinical efficacy in observation group was better than that in control group (Z=2.125, PZ=1.924, PPPPPχ2=5.138, Pα and MMP-3 were lower than that in control group (Pχ2=4.668, PPPPConclusion: In addition to acupuncture and massage therapy, Danlu Tongdu tablets can also be used to relieve pain and ameliorate function, improve clinical efficacy, reduce relapse rate, promote nucleus pulposus reabsorption, and relieve inflammation of nerve root.
ABSTRACT
Objective To investigate the effect of intrathecal(IT)different concentrations of ozone(O_3) on pain threshold,motor function and cerebral spinal fluid(CSF)malondialdehyde(MDA)concentration and superoxide dismutase(SOD)activity and determine if ozone is toxic to central nervous system(CNS).Methods Thirty New Zealand white rabbits of both sexes aged 3-5 months,weighing 2.5-3.0 kg were randomly divided in 5 groups(n=6 each):groupⅠcontrol;groupⅡpure O_2;groupⅢO_2-O_3 30;groupⅣO_2-O_3 50 and groupⅤO_2-O_3 80.The animals were anesthetized with intraperitoneal pentobarbital.Cerebello-medullary cistern was punctured for IT administration of O_2 and O_3.In groupⅡ2 ml of pure oxygen(O_2)(for medical use)was injected IT.In groupⅢ,ⅣandⅤ2 ml of ozone(O_3)30,50 and 80 mg?L~(-1) was injected IT respectively.Ozone was manufactured by ozone generator(Ozoneline Co,Italy).Before and one day after IT O_3 paw withdrawal latency to heat(PWHL)and to mechanical stimulation(yon Frey filament)(PWML)were measured and motor function was assessed(1=normal,4=severe motor dysfunction and weakness).CSF was obtained at 1,2,4 h after IT O_3 for determination of MDA concentration and SOD activity.Results IT administration of the 3 concentrations of ozone did not affect pain threshold and motor function,but significantly increased SOD activity.MDA concentration decreased significantly at 4 h after IT O_2 or ozone administration in groupⅡ,ⅢandⅣ,but increased significantly at 1 and 2 h after IT ozone in groupⅤ.SOD/MDA was significantly increased at 1,2 and 4h after IT ozone in groupⅢandⅣ,but decreased at 1 and 2 h after IT ozone in groupⅤ.Conclusion IT ozone is toxic to CNS.
