ABSTRACT
Objective To explore the effects of stimulating vagus nerve with pulse current on peripheral blood CD4+T lymphocyte of rats with collagen induced arthritis and its mechanism.Methods To duplicate model rats of experimental arthritis(EA)by intradermal injection of Ⅱtype collagen,divide the rats into 2 groups:vagus nerve stimulation(VNS)group and sham operated group.Rats in VNS group were stimulated at the left cervical vagus nerves for 30 minutes a day with constant square wave,pulse current with intra train of 16 Hz,pulse duration of 1.0 ms,train duration of 10 s,interstimulus interval of 1.5 min and intensities of 3.0 mA.Then flow cytometry and immunofluorescence methods were used to detect the activation of CD4+T lymphocytes(expressing CD71)and the expression of nicotinic acetylcholine receptors alpha 7(nAChR?7)and choline acetyltransferase(ChAT)in peripheral blood CD4+T lymphocytes.Results In VNS group,the expression of nAChR?7 and ChAT were significantly raised in CD4+ T cells at 1st weekend(Pa
