OBJECTIVE: To investigate the effects of electro-acupuncture (EA) on the expression of triggering receptor expressed on myeloid cell (TREM)l in ankle joint synovial tissue of acute gouty arthritis (AGA) rats.
METHODS: Forty male SD rats were randomly divided into 4 groups: normal, AGA, medication and EA group, 10 rats in each group. AGA model was established by induced monosodium urate (MSU) method, except the normal group. Tow days before AGA model was established, normal and AGA groups were lavaged with normal saline (20 ml/kg), medication group was lavaged with colchicine solution (20 ml/kg), EA(1.5-2 Hz, D.-D.wave, 9v; 1-3 rnA) was applied to "Sanyinjiao" (SP6), "jiexi" (ST41) and "Kunlun" (BL60) for 20 min, once daily;continuously for 9 days. Then observed the changes in dysfunction, and the content of TNF-α and IL-lβ detected by ELISA, the expression of TREM-l detected by immunohistochemistry and western blot.
RESULTS: Compared to the normal group, the AGA group of the dysfunction index increased significantly (P<0.01), the content of TNF-α and IL-lβ increased significantly (P<0.05), the expression of TREM-l in synovial tissue increased significantly (P<0.05); the medication and EA groups compared to the AGA group, the dysfunction index decreased significantly (P<0.01), the content of TNF-α and IL-lβ decreased significantly (P<0.05), the expression of TREM-l in synovial tissue decreased significantly (P<0.05); there were not statistically significant between the medication and EA group (P>0.05).
CONCLUSION: EA treating AGA may be through down-regulating the expression of TREM -1 in synovial tissue.
