目的探讨脂肪肝超声诊断与血脂和血糖的相关性。方法 204例脂肪肝患者,根据脂肪肝严重程度分为轻度组(60例)、中度组(90例)和重度组(54例);另选取行健康体检超声未诊断为脂肪肝的129例健康者作为对照组。检测四组的血糖和血脂,对比轻度组、中度组、重度组和对照组血糖、血脂水平,并分析血糖、血脂水平与脂肪肝的相关性。结果轻度组、中度组、重度组与对照组血糖及各项血脂指标水平比较,差异具有统计学意义(P<0.05)。血糖、总胆固醇(TC)、甘油三脂(TG)、低密度脂蛋白胆固醇(LDL-C)与脂肪肝呈正相关(r=0.658、0.752、0.649、0.654,P<0.05),高密度脂蛋白胆固醇(HDL-C)与脂肪肝呈负相关(r=-0.744,P<0.05)。结论超声对诊断脂肪肝具有简便、操作性强、重复性好的特点,高血脂、高血糖和脂肪肝密切相关。
Objective To investigate the correlation between ultrasonic diagnosis of fatty liver and lipids and blood glucose. Methods Totally 204 patients with fatty liver were divided into mild group (60 cases), moderate group (90 cases) and severe group (54 cases) according to the severity of fatty liver. Healthy people as a control group. Blood glucose and blood lipids were measured in four groups. The levels of blood glucose and blood lipid in mild group, moderate group, severe group and control group were compared, and the correlation between blood glucose and blood lipid and fatty liver was analyzed. Results The levels of blood glucose and blood lipid in mild group, moderate group, severe group and control group were significantly different (P <0.05). Blood glucose, total cholesterol (TC), triglyceride (TG) and low density lipoprotein cholesterol (LDL-C) were positively correlated with fatty liver (r = 0.658,0.752,0.649,0.654, P <0.05) Cholesterol (HDL-C) was negatively correlated with fatty liver (r = -0.744, P <0.05). Conclusion Ultrasound has the characteristics of simple, operative and good repeatability in the diagnosis of fatty liver, and is closely related to hyperlipidemia, hyperglycemia and fatty liver.
