摘要: 目的 探讨2型糖尿病 (T2DM) 合并非酒精性脂肪肝 (NAFLD) 患者血浆嗜铬蛋白A (CHGA) 与脂肪组织三酰甘油脂肪酶 (ATGL) 的相关性。方法 采用酶联免疫吸附法检测T2DM合并NAFLD组 (A组, 74例)、 T2DM不合并NAFLD组 (B组, 76例) 和正常对照组 (NC组, 75例) 血浆CHGA和ATGL水平, 分析各代谢指标与CHGA、 ATGL的相关性, 回归分析T2DM合并NAFLD的影响因素。结果 血浆CHGA (μg/L) 水平在A组 (83.15±9.46)、 B组 (70.90±2.75) 均高于NC组 (46.74±8.15), A组高于B组 (均P < 0.01)。血浆ATGL (μg/L) 水平在A组 (21.36±13.42)、 B组(40.29±22.83) 均低于NC组 (72.30±26.41), A组低于B组 (均P < 0.01)。在A组患者中, 血浆CHGA与ATGL、 碳水化合物氧化率呈负相关, 与空腹胰岛素 (FINS)、 胰岛素抵抗指数 (HOMA-IR)、 游离脂肪酸 (FFA)、 脂肪氧化率呈正相关; 血浆ATGL水平与体质指数 (BMI)、 FINS、 胆固醇 (TC)、 三酰甘油 (TG)、 HOMA-IR呈负相关, 与FFA呈正相关。多元逐步线性回归分析显示: FINS、 ATGL、 FFA是影响CHGA水平的因素。Logistic回归分析显示: CHGA、 ATGL、 FFA水平是T2DM合并NAFLD的影响因素。结论 血浆CHGA和ATGL与糖脂、 能量代谢密切相关, 且两者可能通过相互作用影响T2DM合并NAFLD的发生发展。

Abstract: Abstract Objective: to explore the relationship between plasma ChromograninA(CHGA ) and Adipose Triglyceride Lipase(ATGL) levels in patients of type 2 diabetes (T2DM) with non-alcoholic fatty liver disease (NAFLD).Methods: The level of the plasma CHGA and ATGL was assayed by enzyme-linked immunosorbent assay (ELISA) in all subjects, patients of T2DM with NAFLD (group A), T2DM without NAFLD(group B)and normal group(group NC). Meanwhile, analysis their relationship with various metabolic index. Results:The plasma CHGA levels of group A and group B are significantly higher than that of group NC(P<0.01) , and its level of group A is higher than that of group B (P<0.01). The plasma ATGL levels of group A and group B are significantly lower than that of group NC(P<0.01) , and its level of group A is lower than that of group B (P<0.01).Correlation analysis showed that the plasma CHGA was negatively correlated to ATGL; meanwhile,it was positively correlated to fasting insulin(FINS),HOMA-IR, free fatty acids(FFA), fat oxidation rate and negatively correlated to carbohydrate oxidation rate;the plasma ATGL was negatively correlated to BMI,FINS,TC,TG,HOMA-IR and positively correlated to FFA. Multiple stepwise regression analysis showed that FINS、ATGL and FFA were independent variables of CHGA. Logistic regression analysis showed that plasma CHGA,ATGL and FFA levels were the independent predictors of T2DM with NAFLD.Conclusion: The plasma CHGA and ATGL levels is closely correlated with substance and energy metabolism, and the interaction between them may play an important role in the pathogenesis of T2DM with NAFLD .
