摘要: 目的 研究系统性红斑狼疮(SLE)患者外周血中辅助性T细胞17(Th17)和辅助性T细胞1(Th1)及其细胞因子白细胞介素17(IL-17)、白细胞介素23(IL-23)和干扰素-γ(IFN-γ)的表达情况及其临床意义。 方法 将38例SLE患者根据SLE活动指数(SLEDAI)评分分为活动组(SLEDAI≥10分)20例和非活动组(SLEDAI<10分)18例;采用流式细胞术检测38例SLE患者和20名健康对照者外周血中Th17和Th1细胞的比例;酶联免疫吸附试验(ELISA) 检测血清中相关细胞因子IL-17、IL-23及IFN-γ的水平,并进行统计学分析。 结果 SLE组外周血中Th17 细胞比例高于对照组(P<0.05),且SLE活动组Th17细胞比例高于非活动组(P<0.05);而Th1细胞比例与对照组比较差异无统计学意义(P>0.05);SLE组血清IL-17、IL-23及IFN-γ水平明显高于对照组(P<0.05);Th17细胞比例及IL-17、IL-23水平与SLEDAI评分呈正相关(r值分别为0.537、0.428、0.525,P值<0.05)。 结论 SLE患者外周血中Th17细胞及血清IL-17、IL-23和IFN-γ水平明显升高,提示Th17与Th1细胞可能在 SLE发病机制中发挥重要作用。

Abstract: Objective To investigate the expressions of T helper cell 17 (Th17) , T helper cell 1 (Th1) and cytokines such as interleukin 17 (IL-17), interleukin 23(IL-23) and interferon-gamma (IFN-γ) in peripheral blood from patients with systemic lupus erythematosus(SLE),and their clinical significance. Methods According to SLE disease activity index (SLEDAI),38 patients with SLE were classified into active group(SLEDAI≥10,20 patients) and inactive group(SLEDAI<10,18 patients). Flow cytometry was used to analyze the percentages of Th17 and Th1 in 38 patients with SLE and 20 healthy controls. The expressions of IL-17, IL-23 and IFN-γ were determined by enzyme-linked immunosorbent assay(ELISA),and the results were analyzed statistically. Results The percentage of Th17 in patients with SLE was significantly higher than that in healthy controls(P<0.05),and the percentage of Th17 in active group was higher than that in inactive group(P<0.05), but the expression of Th1 had no statistical significance with that of healthy controls(P>0.05) . The expressions of IL-17, IL-23 and IFN-γ in patients with SLE were higher than those in healthy controls(P<0.05). The expression of Th17 and the levels of IL-17 and IL-23 were positively correlated  with SLEDAI(r=0.537, 0.428 and 0.525, P<0.05).  Conclusions The expression of Th17 and the levels of IL-17, IL-23 and IFN-γ increase in patients with SLE, and Th17 and Th1 may play important roles in the pathogenesis of SLE.
