OBJECTIVE: Based on relevent theory of prescription and syndrome, to compare the gene expression differences of TLR2, TRAF6, and Faslg with adjuvant arthritis in rat spleen among Wutou decoction, Guizhi Shaoyao Zhimu decoction and Baihu Guizhi decoction. METHOD: The experiment animal model of adjuvant arthritis in rats was established. Relative expression amount of TLR2, TRAF6, and Faslg in rats spleen was detected by SYBR Green I dye methods and implementation of fluorescence quantitative PCR technology with 18sRNA as an internal gene. 2(delta delta CT) method was used for computing and data analysis. RESULT: TLR2, TRAF6, and Faslg gene in adjuvant arthritis rat spleen was significantly higher than those in the blank group. The various doses of Wutou decoction, Guizhi Shaoyao Zhimu decoction and Baihu Guizhi decoction can significantly inhibit or reduce the abnormally high expression of TLR2, TRAF6, and Faslg genes. The gene expression level caused by three decoctions mentioned above was followed by strong to weak as Wutou decoction Guizhi Shaoyao Zhimu decoction and Baihu Guizhi decoction with the clinical equivalent dose, but the strength of the trend to reduce the role of TRAF6 is just the opposite with the TLR2 and Faslg genes. CONCLUSION: Wutou decoction, Guizhi Shaoyao Zhimu decoction and Baihu Guizhi decoction can reduce the abnormally high expression of TLR2, TRAF6 and Faslg in rat spleen with adjuvant arthritis, but the differences of intensity exist and remain relatively consistent with that of pharmacodynamics and regulation trends of T cell subsets. Results suggest that the suppression of TLR2/TRAF6 signal pathway and apoptosis Faslg receptor gene may be the reasons that the pharmacodynamics of three decoctions on peripheral T cell subsets in regulating intensity was different.
