The rat model for NAFLD can be established sucessfully by feeding high fat diet, changes in glycolipid metabolism, oxidative stress and inflammatory reaction of NAFLD rats are similar to human beings, so NAFLD rats are ideal models to study human NAFLD.

2通过高脂饮食可以成功建立大鼠NAFLD模型，该模型存在着糖脂代谢紊乱及氧化应激和炎性反应，与人类NAFLD的病变相似，是研究人类NAFLD的理想模型。

The change of α1,2-FT activity in the cell line before and after the tranfection was confirmed by the determination of enzymatic activity. The changes of cell lipid and glucolipid, especially the change of type Ⅱ oligosaccharide, in the cell line before and after the transfection was determined by Thin-Layer Chromatography and TLC immunostaining method, respectively.

通过酶活性测定证明转染前后细胞系α1，2-FT活性的改变，采用薄层层析、薄层层析免疫染色方法测定转染前后细胞脂质及糖脂，特别是Ⅱ型寡糖的变化。

Background: Glycan-binding proteins could regulate many fundamental and important biological functions, including cell recognition, cell signaling pathway, growth, endocytosis, intracellular, apoptosis, cellular differentiation and infection of pathogenic microorganism through the interaction with glycan of glycoprotein or glucolipid.

研究背景：糖结合蛋白(glycan binding proteins，GBPs)通过和糖蛋白糖链或糖脂糖链的相互作用调控细胞间的识别、信号传递、细胞的内吞和细胞内物质的运输、细胞生长、分化以及凋亡、外界病原微生物的感染等一些最基本的也是最主要的生物学功能。

4The experimental type 2 diabetes with AS rats were yielded by i.p streptozotocin(75mg/kg) and feeding hyperotrophic foods, then we observed the effect of insulin-sensitivity and glycometabolism and lipometabolism on the experimental rats by JTSXKL.

运用链脲佐菌素腹腔注射加含有高胆固醇高脂高糖的高热量饲料喂养建立糖尿病合并动脉粥样硬化大鼠模型，并观察降糖舒心颗粒对该模型大鼠糖脂代谢、胰岛素敏感指数等的影响； 5。

In optimal condition, the biosurfactant concentration can reach 2.2g/L in 150h with 20g/L tetradecane as sole carbon source, the biosurfactant concentration was stable at 165~220mg/L with 20g/L crude oil as sole carbon source.

4在优化条件下，以20g/L十四烷为碳源，培养150小时，糖脂表面活性剂浓度可达到2.2g/L，以20g/L石油为唯一碳源，糖脂浓度稳定在165～220mg/L。

Methods n-Cetyl-l-thio-β-D-galactoside was synthesized by a series of reaction from galactose and incorporated into Small Unilamellar Vesicles which was prepared by sonication at the ratio for L-α-PC∶Chol∶L-α-PE as 7∶2∶1, with or without 10 mol%Cetyl-gal.

半乳糖经乙酰化、溴化、缩合、亲核取代反应制备半乳糖新糖脂质并与其他脂质制备脂质体，在二氯化锡还原作用下用99mTc标记脂质体，进行动物体内靶肝实验，用γ计数器检测各脏器放射性，计算摄取率。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。
