Abstract
Objective To investigate the effect of Treg cells and Th17 cells on the pathogenesis of SLE in patients with SLE,by detecting levels of serum IL-10 and IL-17 in patients with systemic lupus erythematosus (SLE).Methods Selected 54 patients with SLE diagnosed in Suzhou Municipal Hospital Affiliated to Nanjing Medical University from July 2013 to July 2015 as subjects,and 19 healthy persons were selected as control group.Using double antibody sandwich method (ELISA) to detect the levels of IL-10 and IL-17 in two groups.Using indirect immunofluorescence and western blot method to detect ANA,dsDNA,RNP,Sm,SSA and SSB in patients with SLE.Then compared and correlation analysed the level of IL-10 and IL-17,the levels of IL-10 and IL-17 in ANA,RNP,Sm,SSA and dsDNA groups were analyzed simultaneously.Results The level of IL-10 and IL-17 in SLE were 63.7±89.0 pg/ml and 87.7±123.0 pg/ml,and control group were 20.8±8.9 pg/ml and 18.5 ± 111.6 pg/ml,with the statistically significant difference (trL10 =3.484,tIL-17 =4.076,P＜0.01).The level of positive group in SLE were 176.5±93.2 pg/ml and 237.2±107.5 pg/ml,and negative group were 16.2±5.7 pg/ml and 12.9 ±8.3 pg/ml,with the statistically significant difference (tIL-10 =6.875,tIL-17 =8.843,P＜0.01).The level of IL-10 was positively correlated with IL-17 level in SLE (r=0.96,P＜0.05).The level of IL-10 and IL-17 in ANA high titer group were 91.8±100.8 pg/ml and 135.5±140.9 pg/ml,ANA low titer group were 44.5±76.7 pg/ml and 54.4±98.5 pg/ml,with the statistically significant difference (tIL10 =2.215,tIL-17 =2.345,P＜0.05).The level of IL-10 and IL-17 in anti ds-DNA antibody positive group were 87.1 ± 101.1 pg/ml and 122.4 ± 137.1 pg/ml,negative group were 27.4± 50.1 pg/ml and 28.6 ± 61.6 pg/ml,with the statistically significant difference (tIL-10 =2.904,tIL-17 =3.443,P＜0.05).Conclusion The levels of IL-10 and IL-17 were significantly increased and there was positive correlation.It was explained that the anti-inflammatory and pro-inflammatory response existing at the same time in SLE patients and Treg cell and Th17 cell may also play an important role in the occurrence and development in SLE.关键词
