摘 要:目的探讨老年2型糖尿病并发冠心病患者血中性粒细胞与淋巴细胞比值(NLR)的变化及意义。方法采用回顾性病例分析方法,收集2014年4月至2015年7月在贵州省人民医院心内科行冠状动脉造影的老年患者228例,其中糖尿病组77例、冠心病组72例和糖尿病+冠心病组79例,另选70例老年健康体检者为对照组,检测各组白细胞计数、超敏C反应蛋白(hs-CRP)等指标,并计算NLR。Logistic回归分析糖尿病并发冠心病的危险因素,多元逐步回归分析NLR的影响因素。结果糖尿病组、冠心病组及糖尿病+冠心病组与对照组比较,白细胞计数[(7.48±1.81)×10^9/L、(7.72±1.89)×10^9/L(7.98±2.12)×10^9/L与(6.22±1.61)×10^9/L]、中性粒细胞计数[(4.49±1.38)×10^9/L(4.88±1.56)×10^9/L、(5.35±1.40)×10^9/L与(3.52±0.84)×10^9/L]、NLR(2.84±0.77、3.07±0.79、3.34±0.83与1.58±0.42)、hs-CRP[(2.92±0.65)mg/L、(3.20±0.86)mg/L、(4.98±1.10)mg/L与(1.15±0.23)mg/L],均明显升高(P〈0.05或P〈0.01);淋巴细胞计数降低[(1.57±0.41)×10^9/L、(1.58±0.40)×10^9/L、(1.61±0.48)×10^9/L与(2.22±0.51)×10^9/L,P〈0.05];糖尿病+冠心病组NLR、hs-CRP高于糖尿病组和冠心病组(P〈0.05)。Pearson相关分析显示,NLR与Gensini积分、hs-CRP正相关(r值分别为0.7455、0.7792,P〈0.01)。Logistic回归分析显示,NLR、hs—CRP、糖化血红蛋白(HbA1c)是糖尿病并发冠心病的危险因素(0R值分别为4.331、3.997、2.928,P〈0.05)。多元逐步回归分析显示,NLR与空腹血糖、HbA1c、收缩压正相关(标准化回归系数分别为0.3133、0.4720、0.3069,P〈0.05)。结论NLR可能是老年糖尿病患者并发冠心病的一个较好预测指标。Objective To evaluate the value of the neutrophil-lymphocyte ratio (NLR) in elderly type 2 diabetic patients (T2DM) with coronary heart disease (CHD). Methods We performed a retrospective observational study on 228 patients undergoing coronary angiography in Guizhou Provincial People's Hospital from April 2014 to July 2015. Patients were divided into three groups: the simple T2DM group (n=77), simple CHD group (n=72), and T2DM complicated with CHD group (n=79). Meanwhile, 70 healthy elderly subjects served as the control group. The white blood cell count, high-sensitivity C-reactive protein (hs CRP) and other clinical and laboratory parameters were collected, and NLR was calculated. Risk factors for CHD in T2DM patients were determined by logistic regression analysis. Multiple stepwise regression analysis was adopted to identify factors influencing NLR. Results The white blood cell count, neutrophil count, NLR and hs-CRP level in the simple T2DM, CHD, and T2DM+CHD groups were higher than in the control group [(7.48± 1.81) 10^9/L, (7.72±1.89) 10^9/L, (7.98±2.12) 10^9/L vs. (6.22±1.61) 10^9/L; (4. 49±1.38) 10^9/L, (4.88±1.56) 10^9/L, (5.35±1.40) 10^9/Lvs. (3.52±0. 84) 10^9/L; (2.84±0.77), (3.07±0.79), (3.34±0.83)vs. (1.58±0.42); (2.92±0.65)mg/L, (3.20±0.86)mg/ L, (4.98±1.10) mg/L vs. (1.105±0.23) rag/L; respectively, P〈0.05 or P〈0.01]. The lymphocyte count in the simple T2DM, CHD, and T2DM,CHD groups were lower than in the control group [ ( 1.57 ±0.41 ) ×10^9/L, ( 1.58 ±0.40) ×10^9/L, ( 1.61 ± 0.48) × 10^9/L vs. ( 2.22± 0.51) × 10^9/L, P〈0. 05]. NLR and hs-CRP levels in the T2DM+CHD group were higher than in the former two groups (all P〈0.05). Pearson correlation analysis showed that NLR was positively correlated with the Gensini score and hs-CRP level (r=0. 7455 and 0. 7792, both P〈0. 01). Logistic regression analysis showed that NLR, hs-CRP levels and glycos
