摘 要 目的:探讨脂肪肝患者丙氨酸转氨酶(ALT)异常与代谢综合征(MS)之间的相关性。方法:自2015年1月—12月参加本院健康中心体检人员(n=52 092)中,抽取腹部B超提示脂肪肝并接受全套检查者(n=6 508)的体检结果,其中ALT指标异常者806例纳入病例组,ALT指标正常者5 702例纳入对照组。回顾性分析比较两组体格检查、ALT、FPG、血脂全套、SUA、腹部超声等。结果:病例组的BMI、TC、FPG、SUA、SBP水平均高于对照组(P<0.05),而年龄、HDL-C水平低于对照组(P<0.05)。结论:BMI、FPG、血脂、SBP、SUA水平均是脂肪肝患者ALT异常的危险因素。

ABSTRACT Objective: To study the relationship between elevated alanine aminiotransferase (ALT) and metabolic syndrome in the patients with fatty liver disease. Methods: The physical examination results from 6 508 cases with fatty liver prompted by an abdominal B ultrasound examination and receiving a full set of examination were extracted, in which 806 cases with ALT abnormality and the other 5 702 cases with ALT normality were divided into a case group and a control group, respectively. The data including physical examination, ALT, FPG, serum lipid-profile, SUA and ultrasonographic examination of liver were retrospectively analyzed. Results: The levels of BMI, FPG, TC, SUA and SBP were significantly higher in the case group than in the control group (P<0.05). However, the HDL-C level and age were significantly lower in the case group (P<0.05). Conclusion: The levels of BMI, FPG, TC, SUA and SBP are risk factors of ALT abnormality for patients with fatty liver disease.

KEY WORDS fatty liver disease; ALT; metabolic syndrome

作为重要的慢性非传染性疾病,脂肪性肝病现已取代病毒性肝炎,成为全球第一大肝病,对人类健康和社会发展构成严重威胁。丙氨酸转氨酶(alanine aminotransferase,ALT)异常是反映肝细胞损害的肝酶指标之一,监测肝酶、控制肝酶指标对于脂肪肝患者意义重大,影响疾病转归和预后。大多数学者已经将非酒精性脂肪性肝病(nonalcoholic fatty liver disease,NAFLD)作为代谢综合征(metabolic syndrome,MS)的组分之一,或MS在肝脏的表现[1]。本研究旨在探讨脂肪肝患者ALT异常与代谢综合征之间的相关性,寻找导致脂肪肝患者ALT异常的危险因素。

1 资料与方法

1.1 研究对象

2015年1月—12月参加本院健康中心体检人员共52 092人,男性28 567人,女性23 525人,60岁以下41 007人,60岁以上11 085人,与一般体检人群结构相似[2]。抽取其中接受全套检查项目并经腹部超声检查提示脂肪肝的患者6 508例,其中男性4 804例,女性1 704例,平均年龄(45.86±12.49)岁。

1.2 诊断标准

NAFLD诊断:符合中华医学会肝脏病学分会2010年修订的《非酒精性脂肪性肝病诊疗指南》的诊断标准。MS诊断采用改良的2005年国际糖……
