摘要: 目的  探讨主动脉夹层(aortic dissection,AD)合并急性肺损伤(acute lung injury,ALI)与血清C反应蛋白(C-reactiveprotein,CRP)、单核细胞趋化蛋白1(monocyte chemotactic protein 1,MCP-1)、基质金属蛋白酶9(matrix metallprotenaine 9,MMP9)的相关性。
方法  选取AD患者92例进行研究,其中发生ALI患者42例(ALI组),无发生ALI患者50例(非ALI组),选取同期体检健康者50例(对照组),通过酶联免疫吸附法(enzyme-linked immunosorbent assay,ELISA)检测所有受试者血清CRP、MCP-1、MMP9水平,3者表达相关性及对ALI预测价值。
结果  非ALI组和ALI组血清CRP、MCP-1、MMP9水平均高于对照组,ALI组高于非ALI组,差异均有统计学意义(P<0.05)。非ALI组和ALI组血清白细胞介素6(interleukin- 6,IL-6)、、肿瘤坏死因子α(tumor necrosis factor-α,TNF-α)水平均高于对照组,ALI组均高于非ALI组;非ALI组和ALI组血清IL-10均低于对照组,且ALI组低于非ALI组,差异均有统计学意义(P<0.05)。通过Pearson相关性分析显示,ALI组血清CRP与MCP-1、MMP9呈正相关性(r=0.827,P<0.001;r=0.868,P<0.001),MCP-1与MMP9呈正相关性(r=0.741,P<0.001)。 CRP的AUC为0.856,诊断敏感度为66.70%,特异度为88.00%,MCP-1的AUC为0.769,诊断敏感度为69.00%,特异度为76.00%,MMP9的AUC为0.884,诊断敏感度为81.00%,特异度为90.00%,三者联合检测的AUC为0.930,诊断敏感度为83.30%,特异度为90.00%。
结论  AD合并ALI患者血清CRP、MCP-1、MMP9水平升高,3者呈正相关性,CRP、MCP-1、MMP9联合诊断敏感度、特异度高,对AD合并ALI具有较高诊断价值。

Abstract:

Objective  To investigate the correlations between acute lung injury(ALI) in aortic dissection(AD) with serum C-reactive protein(CRP), monocyte chemoattractant protein-1(MCP-1), matrix metalloproteinase-9(MMP9). 

Methods  A total of 92 aortic dissection patients were selected for the study, among them, 42 were ALI patients(ALI group), and 50 were non-ALI patients(non-ALI group), 50 healthy persons(control group) were selected for physical examination during the same period, the levels of serum CRP, MCP-1, and MMP-9 were detected by enzyme-linked immunosorbent assay(ELISA), the correlations of the expressions of CRP, MCP-1, and MMP-9 and their predictive values for ALI were also studied. 
Results  The levels of serum CRP, MCP-1 and MMP9 in non ALI group and ALI group were higher than those in control group, and those in ALI group were higher than those in non ALI group(P<0.05). The levels of serum interleukin-6(IL-6) and tumor necrosis factor-α(TNF-α) in non ALI group and ALI group were higher than those in control group, and those in ALI group were higher than those in non ALI group; Serum IL-10 in non ALI group and ALI group was lower than that in control group, and the difference was statistically significant(P<0.05). Pearson correlation analysis showed that serum CRP was positively correlated with MCP-1 and MMP9(r=0.827, P<0.001; r=0.868, P<0.001), and MCP-1 was positively correlated with MMP9(r=0.741, P<0.001). The AUC of CRP was 0.856, the diagnostic sensitivity was 66.70%, the specificity was 88.00%, the AUC of MCP-1 was 0.769, the diagnostic sensitivity was 69.00%, the specificity was 76.00%, the AUC of MMP9 was 0.884, the diagnostic sensitivity was 81.00%, the specificity was 90.00%. The AUC of combined detection of CRP and MCP-1 was 0.930, the diagnostic sensitivity was 83.30%, and the specificity was 90.00%. 
Conclusion  The levels of CRP, MCP-1, and MMP9 in serum of patients with acute lung injury caused by aortic dissection are increased, and they are positively correlated, the combined diagnosis of CRP, MCP-1, and MMP9 has high sensitivity and specificity, it has high diagnostic value for acute lung injury caused by aortic dissection.
