摘  要:目的研究老年陈旧性心肌梗死患者循环髓样树突状细胞(mDCs)、浆细胞样树突状细胞(pDCs)、总树突状细胞(tDCs)和超敏C反应蛋白质(hs-CRP)水平的变化。方法选择2010年1月至2014年3月老年陈旧性心肌梗死合并慢性左心衰竭患者140例,同期健康对照组50例。采用流式细胞术检测mDCs,pDCs和tDCs水平的变化,免疫散射比浊法测定hs-CRP的水平,并分析其与陈旧性心肌梗死的关系。结果随着老年陈旧性心肌梗死程度的加重,mDCs、pDCs和tDCs水平下降,hs-CRP水平升高。冠状动脉单支病变mDCs、pDCs、tDCs、hs-CRP分别为(1.3±0.5)%、(0.7±0.1)%、(2.0±0.8)%、(5.2±0.8)mg/L;4支病变分别为(O.4±0.2)%、(0.1±0.1)%、(0.6±0.5)%、(16.1±0.7)mg/L(F值分别为1000.1、991.4、879.3、981.2,均P〈0.01)。美国纽约心功能分级(NYHA)I级患者mDCs、pDCs、tDCs、hs-CRP分别为(1.5±0.8)%、(O.9±0.1)%、(2.3±0.8)%、(6.5±0.4)mg/L,IV级患者分别为(0.4±0.3)%、(0.2±0.1)%、(0.6±0.2)%、(15.7±0.9)mg/L,二者比较差异有统计学意义(F值分别为993.7、698.3、719.3、817.4,均P〈0.01);左心室射血分数48%~58%患者mDCs、pDCs、tDCs、hs-CRP分别为(1.5±0.9)%、(0.8±0.1)%、(2.3±0.2)%、(7.4±0.6)mg,25%~35%患者分别为(1.1±0.3)%、(0.5±0.1)%、(1.6±0.7)%、(13.3±0.7)mg/L,二者比较差异有统计学意义(F值分别为563.6、487.0、512.8、496.8,均P〈0.01)。结论mDCs、pDCs、tDCs和hs-CRP水平的变化可能反映老年陈旧性心肌梗死的严重程度。Objective To study changes in the levels of circulating myeloid dendritic cells (mDCs), plasmacytoid dendritic cells (pDCs), total dendritic cells (tDCs) and high-sensitivity C-reactive protein (hs CRP) in elderly patients with old myocardial infarction. Methods A total of 140 elderly patients with old myocardial infarction and chronic left-sided heart failure and 50 healthy controls were enrolled in this study from January 2014 to March 2014. Levels of circulating mDCs, pDCs and tDCs in all patients were measured by flow cytometry. The hs-CRP level was measured by a nephelometric immunoassay. The correlations of circulating mDCs, pDCs, tDCs and hs-CRP with old myocardial infarction were analyzed. Results The levels of circulating mDCs, pDCs and tDCs were decreased and the level of hs CRP was elevated with increasing severity of old myocardial infarction in elderly patients. There were significant differences in the levels of circulating mDCs, pDCs, tDCs and hs CRP between patients with single vessel coronary artery lesions and patients with 4-vessel coronary arterylesions [(1.3±0.5)vs (0. 4±0. 2)%, (0. 7±0.1) vs (0.1±0.1)%, (2.0±0.8%) vs (0.6±0.5)%, (5.2±0.8) mg/L vs (16.1±0.7) mg/L, respectively; F=1000.1, 991.4, 879.3, 981.2, respectively; P〈0.01 for all]. Also, there were significant differences in the levels of mDCs, pDCs, tDCs and hs-CRP between patients with New York Heart Association (NYHA) grade I and patients with NYHAgrade Ⅳ [(1.5±0.8)% vs (0.4±0.3)%, (0. 9±0.1)% vs. (0.2± 0. 1) %, (2.3±0.8) % vs (0.6±0.2) %, (6.5±0.4) mg/L vs (15.7±0.9) mg/L, respectively; F=993.7, 698.3, 719.3, 817.4, respectively; P〈0.01 for all]. The levels of mDCs, pDCs, tDCs and hs-CRP had significant differences between patients with left ventricular ejection fraction (LVEF) of 48%-58% and patients with LVEF of 25%-35%[(1.5±0.9)% vs. (1.1±0.3%), (0. 8±0.1%) w (0.5±0.1)%, (2.3±0.2)% vs. (1.6±0
