RESUMEN
Objective To explore the role of Th17 cells in systemic lupus erythematosus (SLE)with cardiovascular disease (CVD).Methods 61 patients of SLE were collected from September 2011 to March 2013 in the Second Hospital of Hebei Medical University by revised SLE classification standards of ACR in 1997.These patients were divided two groups:22patients of SLE with CVD and 39 patients of SLE without CVD;the control group include 20 healthy.Th17 cells were measured by flow cytometry,IL-1 7 was detected by enzyme-linked immunosorbent assay.The correlation among them and the disease active index were analyzed.Results ①The percent of Th1 7 cells in the group of SLE with CVD,that in the group of SLE without CVD and that in control group were (2.09±0.98)%,(1.75±0.75)% and (0.89±0.44)%,respec-tively.The percent of Th1 7 cells in healthy group were lower than that in SLE with CVD and SLE without CVD group (t=4.717~5.030,P0.05;t=1.513,P>0.05).②The level of IL-17 were correlated positively with SLEDAI and the anti-double strand DNA (r=0.393,P=0.008;r=0.558,P<0.001),were correlated negatively with complement C3 (r=-0.423,P=0.005).The percent of Th17 cells in CD4+T cells were correlated positively with SLEDAIand the anti-double strand DNA (r=0.681,P<0.001;r=0.492,P=0.015)were correlated negatively with complement C3 (r=-0.534,P=0.027).Con-clusion The level of Th1 7 cells and IL-1 7 were high in SLE,and they were related with the disease activity.The cardiovas-cular factor had not affect the expression of Th1 7 cells and IL-1 7 in SLE.
