| 摘 要： | 目的探讨瘦素、脂联素在非酒精性脂肪肝病的发生及发展过程中的作用。方法以高脂高胆固醇饲料喂养制作大鼠非酒精性脂肪肝病模型,设立正常对照组和模型6周组、12周组、18周组。测量动物的体重、肝重,常规HE染色观察肝脏病变,酶联免疫法测定血清和肝组织瘦素和脂联素含量。结果病理学观察显示:模型组6周末呈现单纯性脂肪肝,12周末符合脂肪性肝炎表现,18周末呈现肝硬化;与正常对照组相比,模型组血清瘦素含量从6周末开始显著升高,12周末达最高,18周末又回降,但仍高于正常对照组(P<0.05),肝组织炎症活动度(HAI)变化趋势与之相同,且二者呈显著正相关;模型组血清脂联素6周末开始呈显著梯度下降趋势(P<0.05),肝组织羟脯氨酸(Hyp)含量变化趋势与之相反,两者呈显著负相关。结论在非酒精性脂肪肝病发生发展过程中,血清瘦素升高可能加速单纯性脂肪肝向脂脂性肝炎的转化,而血清脂联素稳定可能抑制肝纤维化的进展。 |
