Diabetic cardiomyopathy (DCM) is one of the most severe complications of diabetes without a clear pathogenesis. Th is study investigated the adiponectin (APN) and leptin levels in type II DCM, as well as their correlation with advanced glycation end-products (AGEs). From 2011-2013, 78 type II diabetes mellitus (T2DM) cases (40-65 years old) in the Taian region were randomly selected. Based on the results of colour Doppler ultrasonography and coronary angiography, the cases were divided into a simple T2DM group (40 cases) and a DCM group (38 cases). Forty healthy subjects were used as normal control (NC). An enzyme-linked immunosorbent assay was performed to determine the levels of fa tty inflammatory factors such as APN, leptin and AGEs, and a correlation analysis was conducted. In the T2DM group, the APN levels were decreased but the leptin and AGE levels were significantly increased compared to the NC group. In the DCM group, the APN levels were decreased but the leptin and AGE levels were significantly increased (P<0.01) compared to the T2DM group. Th e AGE levels were positively correlated with disease progression and with fasting plasma glucose levels, glycated haemoglobin, insulin resistance and leptin, but were negatively correlated with APN levels. Additionally, the APN and leptin levels were independently related to the AGE levels. Fatty inflammatory factors play a significant role in the progression of both simple T2DM and DCM. Th e results of this study revealed the pathogenesis of DCM and indicated the potential significance of AGEs in DCM prevention and treatment.
糖尿病性心肌病(DCM)是糖尿病最严重的并发症之一,其发病机制尚不明确。本研究调查了II型DCM患者的脂联素(APN)和瘦素水平,以及它们与晚期糖基化终产物(AGEs)的相关性。2011年至2013年,随机选取泰安市地区78例II型糖尿病(T2DM)患者(年龄40 - 65岁)。根据彩色多普勒超声心动图和冠状动脉造影结果,将患者分为单纯T2DM组(40例)和DCM组(38例)。选取40名健康受试者作为正常对照组(NC)。采用酶联免疫吸附测定法测定APN、瘦素和AGEs等脂肪炎症因子水平,并进行相关性分析。在T2DM组中,与NC组相比,APN水平降低,但瘦素和AGE水平显著升高。在DCM组中,与T2DM组相比,APN水平降低,但瘦素和AGE水平显著升高(P<0.01)。AGE水平与疾病进展、空腹血糖水平、糖化血红蛋白、胰岛素抵抗和瘦素呈正相关,但与APN水平呈负相关。此外,APN和瘦素水平与AGE水平独立相关。脂肪炎症因子在单纯T2DM和DCM的进展中起重要作用。本研究结果揭示了DCM的发病机制,并表明AGEs在DCM防治中的潜在意义。
