非酒精性脂肪肝(NAFLD)发病率呈上升趋势,NAFLD可发展成肝纤维化致肝细胞癌[1],是隐源性肝硬化的重要原因。我们于2003年1月至2005年3月通过临床病例对照研究,调查高原地区NAFLD的临床特点并探讨其相关危险因素,为NAFLD的早期诊断和预防提供理论依据,报告如下。对象与方法1.一 The incidence of non-alcoholic fatty liver disease (NAFLD) is on the rise. NAFLD can develop into hepatocellular carcinoma caused by liver fibrosis [1], which is an important cause of cryptogenic cirrhosis. We conducted a clinical case-control study from January 2003 to March 2005 to investigate the clinical features of NAFLD in the plateau area and to explore the related risk factors to provide a theoretical basis for the early diagnosis and prevention of NAFLD. The report is as follows. Objects and methods 1. One
