Flyblow chitosan has distinct preventive effect on hypercholesterolemia,its effect is related to the deacetylation degree.

蝇蛆壳聚糖具有明显降血脂作用，其作用与脱乙酰程度呈正相关。

Methods The chemical method was used to prepare 72.3%,80.5%,96.1% deacetylated flyblow chitosan and IR was used to identify its structure.

采用酸碱化学法制备72.3%，80.5%，96.1%脱乙酰度的蝇蛆壳聚糖，并用红外扫描鉴定其结构。

Adult male SD rats were randomly divided into five groups:control group、hypercholesterolemia control group、dosage group with 72.3%,80.5%,96.1% deacetylated flyblow chitosan.The rats were fed with a high cholesterol diet and were administrated flyblow chitosan continuously for 8 weeks at the same time,then the blood lipid and weight were measured.

取成年雄性SD大鼠随机分为5组，分别为正常对照组、高脂模型组、蝇蛆壳聚糖72.3%，80.5%，96.1%脱乙酰度组，给高脂饲料造模的同时连续给予蝇蛆壳聚糖8周，测定大鼠血清总胆固醇、甘油三酯、高密度脂蛋白、低密度脂蛋白含量，同时观察对大鼠体重影响。

In young human umbilical vein endothelial cells, human aortic endothelial cells, and human coronary artery endothelial cells, miR-217 induces a premature senescence-like phenotype and leads to an impairment in angiogenesis via inhibition of SirT1 and modulation of FoxO1 (forkhead box O1) and endothelial nitric oxide synthase acetylation.

在婴儿脐静脉内皮细胞、人类主动脉内皮细胞以及冠状动脉内皮细胞中，miR-217可以诱导这些细胞出现一种早衰样表型，进而通过抑制SirT1的表达、调控Fox01以及内皮细胞一氧化氮合酶的乙酰化来损伤新生血管的形成。

Glycoside of lectins was mainly composed of D-mannose, D-glucose and N-GlcNAc. However, Lec3 also contain some fucose.

研究表明三种凝集素的糖基主要由甘露糖，葡萄糖，N-乙酰氨基葡萄糖构成，Lec3糖基中还含有部分岩藻糖。

BACKGROUND: The choline acetyltransferase is the key synthetic enzyme for acetylcholine, and is the important symbol of the functional activity of the cholinergic system.

背景：胆碱乙酰化转移酶是乙酰胆碱合成的关键酶，是胆碱能神经系统功能活动的重要标志。

In addition, the effects of temperature and concentration of sulfuric acid on the concentration of LA and 5-hydroxymethyl furfural were shown.

实验考察了不同温度和硫酸浓度对葡萄糖分解的主要产物5-羟甲基糠醛和乙酰丙酸浓度的影响。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
