目的,2,明确荷叶对高脂血症(HLP)模型大鼠水通道蛋白(AQPs)及水液代谢的调节作用及机制。,方法,2,采用高脂饲料饲养建立高脂血症SD大鼠模型。随机分为正常组、模型组、依折麦布组、荷叶组,每组7只。正常组与模型组予纯水灌胃,给药组分别予以相应剂量依折麦布及荷叶水提物灌胃,1次/d,连续给药6周。采用全自动生化分析仪检测血清三酰甘油(TG)指标;ELISA法检测血清胃泌素(GAS)、胃动素(MTL)和Na,+,-K,+,-ATP酶水平;RT-qPCR法检测结肠组织,AQP3,、,AQP8,和,AQP9 ,mRNA表达水平;HE及油红O染色观察肝组织病理学改变情况。,结果,2,与模型组比较,荷叶组大鼠血清TG及MTL水平降低,GAS水平和Na,+,-K,+,-ATP酶含量升高,结肠组织,AQP8,、,AQP9, mRNA表达降低(,P,<,0.05),肝组织脂质沉积减轻。,结论,2,荷叶对高脂血症模型大鼠TG水平具有一定的调节作用,其机制可能与调节水通道蛋白表达,改善脾主运化功能及水液代谢有关。
Objective,2,To investigate the regulation and mechanism of Nelumbinis Folium on aquaporins (AQPs) and water metabolism in hyperlipidemia (HLP) model rats.,Methods,2,A hyperlipidemic SD rat model was established with high-fat diet feeding. The rats were randomly divided into normal group, model group, ezetimibe group and Nelumbinis Folium group, with 7 rats in each group. Rats in normal group and model group were given intragastric administration of pure water, and rats in other two groups were given intragastric administration of ezetimibe or Nelumbinis Folium water extract in respective doses, once a day for 6 consecutive weeks. Serum triacylglycerol (TG) samples were detected by automatic biochemical analyzer; Serum gastrin (GAS), motilin (MTL) and Na,+,-K,+,-ATPase levels were determined by ELISA; The mRNA expression of ,AQP3,, ,AQP8, and ,AQP9, in colon tissue were detected by RT-qPCR; and Hmatoxylin-Eosin (HE) staining and oil red O staining were applied to observe the pathological changes of liver tissues.,Results,2,Compared with the model group, Nelumbinis Folium group showed decreased serum TG and MTL levels, significantly increased GAS and Na,+,-K,+,-ATPase content, down-regulated mRNA expression of ,AQP8, and ,AQP9, in colon tissues, and significantly reduced lipid deposition in liver cells of HLP model rats.,Conclusion,2,Nelumbinis Folium has a regulatory effect on TG levels in HLP model rats, and the mechanism may be related to regulating the expression of aquaporins, improving the transportation and transformation function of the spleen and water metabolism.
