Abstract:
OBJECTIVES: To study the expression level of plasma miR-106b-5p in primary immune thrombocytopenia (ITP) and its correlation with the levels of T helper 17 cell (Th17) and regulatory T cell (Treg) and the Th17/Treg ratio. METHODS: A total of 79 children with ITP (ITP group) and 40 healthy children (control group) were selected as subjects. According to the treatment response, the 79 children with ITP were divided into three groups: complete response (n=40), partial response (n=18), and non-response (n=21). Quantitative real-time PCR was used to measure the expression level of miR-106b-5p. Flow cytometry was used to measure the frequencies of Th17 and Treg, and the Th17/Treg ratio was calculated. The correlation of the expression level of plasma miR-106b-5p with the frequencies of Th17 and Treg and the Th17/Treg ratio was analyzed. RESULTS: Compared with the control group, the ITP group had significantly higher levels of miR-106b-5p, Th17, and Th17/Treg ratio (P<0.05) and a significantly lower level of Treg (P<0.05). After treatment, the ITP group had significant reductions in the levels of miR-106b-5p, Th17, and Th17/Treg ratio (P<0.05) and a significant increase in the level of Treg (P<0.05). Compared with the partial response and non-response groups, the complete response group had significantly lower levels of miR-106b-5p, Th17, and Th17/Treg ratio (P<0.05) and a significantly higher level of Treg (P<0.05). The correlation analysis showed that in the children with ITP, the expression level of plasma miR-106b-5p was positively correlated with the Th17 level and the Th17/Treg ratio (r=0.730 and 0.816 respectively; P<0.001) and was negatively correlated with the Treg level (r=-0.774, P<0.001). CONCLUSIONS: A higher expression level of miR-106b-5p and Th17/Treg imbalance may be observed in children with ITP. The measurement of miR-106b-5p, Th17, Treg, and Th17/Treg ratio during treatment may be useful to the evaluation of treatment outcome in children with ITP. 目的: 探讨血浆miR-106b-5p在原发免疫性血小板减少症（primary immune thrombocytopenia，ITP）中的表达及其与辅助性T细胞17（T helper cells 17，Th17）、调节性T细胞（T regulatory cell，Treg）、Th17/Treg的相关性。方法: 选取79例ITP患儿（ITP组）和40例健康儿童（对照组）为研究对象。79例ITP患儿根据治疗效果分为完全有效组（40例）、有效组（18例）、无效组（21例）。采用实时荧光定量PCR技术检测miR-106b-5p表达水平，流式细胞技术检测Th17和Treg，计算Th17/Treg，分析血浆miR-106b-5p表达水平与Th17、Treg及Th17/Treg的相关性。结果: ITP组miR-106b-5p、Th17及Th17/Treg水平高于对照组（P<0.05），Treg水平低于对照组（P<0.05）。ITP组患儿治疗后miR-106b-5p、Th17、Th17/Treg水平低于治疗前（P<0.05），Treg水平高于治疗前（P<0.05）。完全有效组miR-106b-5p、Th17、Th17/Treg水平低于有效组和无效组（P<0.05），Treg水平高于有效组和无效组（P<0.05）。相关分析显示，ITP患儿血浆miR-106b-5p表达水平与Th17、Th17/Treg均呈正相关（分别r=0.730、0.816，均P<0.001），与Treg呈负相关（r=-0.774，P<0.001）。结论: ITP患儿存在miR-106b-5p高表达和Th17/Treg比例失衡，在ITP患儿治疗过程中检测miR-106b-5p、Th17、Treg及Th17/Treg水平，对ITP患儿的疗效判断具有较好的指导作用。.
