摘　　要：目的分析2型糖尿病(T2DM)合并糖尿病视网膜病变(DR)患者血清乙醛脱氢酶2(ALDH2)和过氧化氢酶(CAT)活性,并探讨其临床诊断价值。方法选取该院2020年4月至2021年11月206例T2DM患者,根据视网膜是否发生病变分为单纯T2DM组(T2DM组,n=103)和T2DM合并DR组(T2DM+DR组,n=103),另选取该院同期103例体检健康者为对照组。检测血清ALDH2、CAT活性,Pearson相关性分析T2DM合并DR患者血清ALDH2、CAT与糖化血红蛋白、甘油三酯、空腹血糖(FBG)、餐后1 h血糖(1 hPG)及胰岛素抵抗指数(HOMA-IR)的关系,多因素Logistic回归分析T2DM合并DR的影响因素,受试者工作特征(ROC)曲线分析血清ALDH2、CAT对T2DM合并DR的临床诊断价值。结果对照组、T2DM组、T2DM+DR组患者血清ALDH2、CAT活性依次逐渐降低(P<0.05)。多因素Logistic回归分析结果显示,糖化血红蛋白、1 hPG、HOMA-IR、糖尿病病程及ALDH2、CAT活性是T2DM合并DR的影响因素(P<0.05)。Pearson相关性分析结果显示,T2DM合并DR患者血清ALDH2、CAT与糖化血红蛋白、甘油三酯、FBG、1 hPG及HOMA-IR均呈负相关(P<0.05)。ROC曲线分析结果显示,ALDH2和CAT联合诊断T2DM合并DR的曲线下面积(AUC)明显大于ALDH2单独诊断的AUC(Z=2.563,P=0.010)及CAT单独诊断的AUC(Z=1.984,P=0.047)。结论T2DM合并DR患者血清ALDH2、CAT活性降低,二者联合检测对T2DM合并DR具有较高的诊断价值。Objective To analyze the activity of serum aldehyde dehydrogenase 2(ALDH2)and catalase(CAT)in patients with type 2 diabetes mellitus(T2DM)complicated with diabetic retinopathy(DR),and to explore its clinical diagnostic value.Methods A total of 206 T2DM patients in this hospital from April 2020 to November 2021 were selected and divided into T2DM group(T2DM group,n=103)and T2DM combined with DR group(T2DM+DR group,n=103)according to the presence or absence of retinopathy.Another 103 physical examination healthy people during the same period in the hospital were selected as the control group.Serum ALDH2 and CAT activities were measured.Pearson correlation analysis was used to analyze the relationship between serum ALDH2,CAT and glycosylated hemoglobin,triglyceride,fasting blood glucose(FBG),1 h postprandial blood glucose(1 hPG)and insulin resistance index(HOMA-IR)in T2DM patients with DR.Multivariate Logistic regression was used to analyze the influencing factors of T2DM with DR.Receiver operating characteristic(ROC)curve was used to analyze the clinical diagnostic value of serum ALDH2 and CAT for T2DM with DR.Results The serum ALDH2 and CAT activities were gradually decreased in the control group,T2DM group and T2DM+DR Group(P<0.05).Multivariate Logistic regression analysis showed that glycosylated hemoglobin,1 hPG,HOMA-IR,duration of diabetes,ALDH2 and CAT activity were the influencing factors of T2DM patients with DR(P<0.05).Pearson correlation analysis showed that the levels of ALDH2 and CAT were negatively correlated with glycosylated hemoglobin,triglyceride,FBG,1 hPG and HOMA-IR in T2DM patients with DR(P<0.05).ROC curve analysis showed that the area under the curve(AUC)of ALDH2 combined with CAT in the diagnosis of T2DM patients with DR was significantly higher than AUC of ALDH2 alone(Z=2.563,P=0.010)and CAT alone(Z=1.984,P=0.047).Conclusion The serum ALDH2 and CAT activities are decreased in T2DM patients with DR.The combined detection of ALDH2 and CAT has a high diagnostic value for T2DM patients with DR.
