RESUMEN
Objective: To investigate the effects of immunotherapy on PRA, TGF-β and CD4+CD25+Foxp3+ nTreg cells in women with unexplained recurrent spontaneous abortion. Methods:We detect the level of PRA,TGF-βin serum and the expression of nTreg cells in peripheral blood of pregnant, non pregnant and natural fertility women by enzyme immunoassay and flow cytometry. Results:After immunotherapy,the median level of PRA and TGF-βin non pregnant group was lower than that in pregnant group(27. 5%,107. 7 pg/L vs 68. 75%,189. 9 pg/L,P<0. 01). Compared to pregnant group,the median expression rate of nTreg cells were lower in non pregnant group(5. 05% vs 8. 05%,P<0. 01). Conclusion:The PRA,TGF-βand nTreg cells are critical factors for pregnancy in RSA patients. It is helpful to identify and judge the effect of immunotherapy by detect the level of panel reactive antibodies,TGF-β in serum and the expression rate of nTreg cells in peripheral blood.
RESUMEN
Objective:To explore the effect of Jiudaiqingyuan oral liquid in strengthening immunologic function of children with RRI.Methods:100 children with RRI were randomly divided into two groups:the routine treatment group(RTG) and the group treated with Jiudaiqingyuan oral liquid (JDG).Venous blood was drawn before and after treatment to detect T lymphocyte subsets(SP method),NK cell activity (MTT method),sIL 2R(ELISA method),IgG,IgA,IgM(transmission turbidimetric method).Results:CD3 +,CD4 +,CD4 +/CD8 +,NK cell activity and IgG,IgA of the children with RRI were notably lower and CD8 +、IgM、sIL 6R markly higher before treatment.These indexes recovered to some extent after routine treatment but were still significantly different from those of normal controls(P0 05).Conclusion:Jiudaiqingyuan oral liquid has strong effect on immunologic regulation.It may markly enhance cellular and humoral function of children with RRI.
