摘 要 目的:分析核转录因子-κB(NF-κB)与小鼠肝脏脂肪变性、血清谷丙转氨酶(ALT)水平的关系。方法:将20只小鼠随机分为非酒精性脂肪肝组(高脂饮食饲养)和对照组(正常饲养),各10例。分别在10周、14周时测定ALT水平和NF-κB含量,观察两组肝组织病理形态。结果:非酒精性脂肪肝组干预10、14周时肝组织内NF-κB含量、血清ALT水平、白介素(IL)-6、IL-1β水平均高于对照组(P<0.05)。NF-κB含量与血清ALT水平呈正相关性(P<0.05)。结论:NF-κB含量增高,可导致小鼠肝脏脂肪变性,且与血清ALT水平呈正相关性。

ABSTRACT Objective: To analyze the relationship between nuclear transcription factor-κB (NF-κB) and liver steatosis and serum alanine aminotransferase (ALT) level in mice. Methods: Twenty mice were randomly divided into a non-alcoholic fatty liver group (fed on a high-fat diet) and a control group (fed on a normal diet), with 10 cases each. Serum ALT levels and NF-κB content were determined at 10 and 14 weeks, and pathological morphology of liver tissues was observed in the two groups. Results: The content of NF-κB in liver tissue, the serum ALT, interleukin-6, and IL-1β levels determined at 10 and 14 weeks of intervention in the non-alcoholic fatty liver group were all higher than those in the control group (P<0.05). There was a positive correlation between NF-κB content and serum ALT level (P<0.05). Conclusion: The increase of NF-κB content can lead to steatosis in the liver of mice and has a positive correlation with serum ALT level.

非酒精性脂肪肝(nonalcoholic fatty liver,NAFL)是危害全球人类健康的常见慢性肝脏疾病,其病理特征是非酒精性因素导致肝细胞内脂肪变性,是诸多代谢性疾病的危险因素[1]。若干预不及时,随着疾病的不断进展,可逐渐发展至脂肪性肝炎、肝纤维化以及肝癌,威胁到患者的生命安全[2]。核转录因子-κB(nuclear transcription factor,NF-κB)主要分布在脂肪组织中,参与了多种基因的转录,调控多种细胞因子、黏附分子及趋化因子的表达,并与脂肪代谢过程、炎症反应密切相关[3]。谷丙转氨酶(alanine aminotransferase, ALT)主要分布在肝细胞胞浆内,正常时仅有少量释放入血,在病毒性肝炎急性期或肝细胞坏死时,ALT大量释放入血,是诊断肝脏疾病的重要标志物[4]。因此,明确NAFL的发病机制,提高临床治疗特异性显得极其重要。本研究拟在小鼠模型中分析NF-κB含量与小鼠肝脏脂肪变性、血清ALT水平的關系,旨在为临床病理研究提供参考。……
