【摘要】目的探讨急性有机磷中毒(AOPP)患者细胞因子水平与miR-93表达的关联性。方法选取2015年7月至2017年2月收治确诊AOPP的 35例患者作为实验组,选择同期30例健康就诊者作为对照组,对比观察两组患者肿瘤坏死因子-α(TNF-α)、可溶性血管细胞黏附分子-1(sVCAM-1)、促炎因子白细胞介素-1β(L-1β)和miR-93表达水平。结果实验组TNF-α、sVCAM-1和IL-1β高于对照组(P<0.001),miR-93表达水平低于对照组(P<0.001)。实验组不同年龄miR-93水平均较对照组低(P<0.05或0.01)。miR-93表达与TNF-α、sVCAM-1、IL-1β水平呈负相关,相关系数分别为-0.694、-0.621和-0.665,对应F值分别为74.828、54.065、65.627(均P<0.001)。结论AOPP不同年龄患者的miR-93呈低表达现象,miR-93表达与TNF-α、sVCAM-1和IL-1β水平呈负相关,miR-93或许参与AOPP的病理生理过程。

【Abstract】ObjectiveTo investigate connection between cytokine levels and miR-93 expression in patients with AOPP(acute organophosphorus pesticide poisoning).Methods35 cases admitted to hospital and confirmed with AOPP from July,2015 to February,2017 were selected as experimental group,and 30 healthy people were selected as control group at the same time.Then,tumor necrosis factor-α(TNF-α),soluble vascular cell adhesion molecule-1(sVCAM-1),proinflammatory cytokines interleukin-1β(L-1β)and miR-93 expression levels were observed and compared between the two groups.ResultsTNF-α,IL-1β and sVCAM-1 of the experimental group were higher than those of the control group(P<0.001),but miR-93 expression level was lower than that of the control group(P<0.001).The miR-93 levels at different ages in the experimental group were lower than those in the control group(P<0.05 or 0.01).The miR-93 expression was negatively correlated with TNF-α,sVCAM-1 and IL-1β,and correlation coefficient was -0.694,-0.621,-0.665,respectively,and corresponding F value was 74.828,54.065,and 65.627,respectively(all P<0.001).ConclusionMiR-93 expression is low in patients with AOPP at different ages,it is negatively correlated with TNF-α,sVCAM-1 and IL-1β.So miR-93 may involve in the pathophysiological process of AOPP.

急性有机磷中毒(Acute organophosphorus pesticide poisoning,AOPP)患者,因各种原因引起有机磷误进入机体后,其磷酰基与乙酰胆碱酶的活性部分结合成磷酰化胆碱酯酶,后者不能分解乙酰胆碱,患者体内乙酰胆碱异常升高,其胆碱能神经过度兴奋,最后转入抑制和衰竭,出现临床症状和体征[1]。AOPP患者的症状和转归与其机体的某些炎症代谢异常有关[2],患者的内皮功能受损,巨噬细胞被活化,引起多种细胞因子的释放[3]。miRNA与疾病的发生发展有关, miRNA-93通过调节某些炎症因子的表达水平,从而影响患者对疾病的抵御反应,但其机制还需进一步研究[4]。为了解AOPP患者miR-93和炎症因子表达水平的关联性,我们检测35例AOPP患者肿瘤坏死因子-α(TNF-α)、可溶性血管细胞黏附分子-1(sVCAM-1)、促炎因子白细胞介素-1β(L-1β)和miR-93表达水平,并与30例健康者比较,总结报告如下。
