ABSTRACT
ObjectTo analyze the effect of muscular tension injury in spasticity of cerebral apoplexy(SCA) rats with spasticity and the expression of γ-aminobutyric acid receptor (GABAα), γ-aminobutyric acid transporter (GAT-1) protein and mRNA expression in cerebral cortex modified Shaoyao Gancaotang, electroacupuncture Quchi, Yanglingquan and acupuncture combined with herb therapies alleviate the effect of SCA.

Method:

Randomly divided into two groups, divided into blank group, sham operation group, model group, modified Shaoyao Gancaotang group, acupuncture combined with herb group, electroacupuncture group, selected qualified SD rats into the group, 9 rats in each group. The modified Zea-Longa thread embolism method+internal capsule injection of NMDA receptor method was used to prepare a rat model. After the behavioral score confirms the success of the model,dispose of each group separately,electroacupuncture group (electroacupuncture on both sides of Yangling Spring and Quchi,1 time/d for 5 days), modified Shaoyao Gancaotang group (with Shaoyao Gancaotang 1 time/d,10 mL·kg-1 for 5 days),acupuncture combined with herb (modified Shaoyao Gancaotang was given, then electroacupuncture treatment was continued for 5 days). After treatment, the muscle tension was detected by behavioral analysis. Real-time fluorescent quantitative PCRReal-time PCR) and Western blot were used to detect the expression of GABAα and GAT-1 related mRNA and protein in the cortex.

Result:

Compared with normal group, the muscle tension of the model group increased (P<0.01), the expression of GABAα mRNA and protein decreased (P<0.01), and the expression of GAT-1 mRNA and protein increased (P<0.01), compared with model group, the muscle tone score of the each treatment group decreased (P<0.05), the expression of GABAα mRNA and protein increased (P<0.05,P<0.01), and the expression of GAT-1 mRNA and protein decreased (P<0.05,P<0.01), of which the corresponding expression in the acupuncture combined with herb group was the most significant.

Conclusion:

Electroacupuncture Quchi, Yanglingquan,modified Shaoyao Gancaotang and acupuncture combined with three therapies can alleviate the muscle tension of limbs spasm of stroke,and the combination of acupuncture and medicine treatment on the cortical γ-aminobutyric acid receptor the highest expression efficiency suggests that it has the best effect on improving the excitatory spasticity of stroke limbs.
