Résumé

Objective::To investigate the effects of modified Buwangsan on the learning and memory ability of Alzheimer's disease (AD) model rats and the expression of NOD-like receptor 3 (NLRP3), cysteine-containing aspartate-specific proteases 1 (Caspase-1) and interleukin-1 beta (IL-1β) in NLRP3 inflammatory pathway in hippocampus of AD model rats, and exploring the underlying mechanism of modified Buwangsan. Method::The 52 eligible rats were randomly divided into sham control group, AD model group, low-dose modified Buwangsan group (1.5 g·kg-1) and high-dose modified Buwangsan group (3 g·kg-1). AD mouse model was established by bilateral hippocampus injection of Aβ1-425 μL (2 g·L-1). The rats in low-dose and high-dose modified Buwangsan group received low and high dose modified Buwangsan respectively within the next 4 weeks, once daily. The learning and memory ability was tested by Morris water maze. The expression of NLRP3, Caspase-1 and IL-1β mRNA was tested by quantitative PCR(Real-time PCR) and Western blot. Result::As compared with the sham group, the learning and memory ability of the rats were significantly impaired (P<0.05). Compared with AD model group, the learning and memory ability and the expression levels of NLRP3, Caspase-1, and IL-1β mRNA and protein were all no statistical differences in low-dose modified Buwangsan group, while the learning and memory ability of the rats were significantly improved and the expression of NLRP3, Caspase-1 and IL-1β mRNA in hippocampus of rats was significantly decreased in high-dose modified Buwangsan group (P<0.05). Conclusion::High-dose modified Buwangsan could attenuate neuroinflammation in the hippocampus of AD mouse model via inhibiting the expression of NLRP3, Caspase-1 and IL-1β, which may be the mechanisms of modified Buwangsan could be used to ameliorate the learning and memory ability of AD mouse model.

Résumé

OBJECTIVE@#To explore the clinical efficacy of acupuncture combined with granule for nerve-root type cervical spondylosis and its effects on serum interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β) and hemorheological indexes.@*METHODS@#A total of 114 patients with nerve-root type cervical spondylosis were randomly divided into an observation group and a control group, 57 cases in each group. The patients in both groups were treated with traction. The patients in the control group were treated with oral administration of granule, 4 g each time, 3 times a day, while based on the treatment of control group, the patients in the observation group were treated with acupuncture at Dazhui (GV 14), Tianzhu (BL 10), Houxi (SI 3), cervical Jiaji (EX-B 2), Quchi (LI 11), Hegu (LI 4) and Waiguan (TE 5), once a day. Both groups were treated for 4 weeks. The simplified McGill pain questionnaire (MPQ), neck disability index (NDI), numbness score, levels of IL-6, TNF-α, IL-1β in serum and hemorheological indexes were observed before and after treatment, and the clinical efficacy was compared between the two groups.@*RESULTS@#The total effective rate was 91.2% (52/57) in the observation group, which was higher than 71.9% (41/57) in the control group (<0.05). Compared before treatment, the scores of MPQ, NDI and numbness in the two groups were reduced after treatment (<0.05). After treatment, the scores of MPQ, NDI and numbness in the observation group were lower than those in the control group (<0.05). After treatment, the serum levels of IL-6, TNF-α and IL-1β in the two groups were reduced (<0.05), and those in the observation group were lower than the control group (<0.05). After treatment, the plasma viscosity, fibrinogen, low shear rate of whole blood viscosity and high shear rate of whole blood viscosity in the two groups were lower than before treatment (<0.05), and those in the observation group were lower than the control group (<0.05).@*CONCLUSION@#Acupuncture combined with granule have significant clinical efficacy for nerve-root type cervical spondylosis, which could reduce the serum levels of IL-6, TNF-α and IL-1β and improve hemorheology.
