The result indicated that ZXTMN group excelled the western medicine in the aspects of ameliorating symptom and hemodynamics, adjusting sugar and lipid metabolism, and reducing urine albumin and pltaelet adhesiveness and aggreagtion. The mechanism, which ZXTMN prescription could protect renal function, probably was (1) decreasing the level of sugar and glycosylated ferrohemoglobin;(2) decreasing AR activity of erythrocyte, improving SDH activity of erythrocyte, reducing accumulation of sorbitol in the erythrocyte, thus ameliorating the polyol metabolism;(3) accommodating lipid metabolism;(4) ameliorating coagulation, gathering, thick and mucosity of patient blood.

结果表明，止消通脉宁治疗组明显优于西药对照组，在改善症状，调整糖、脂代谢，减少尿白蛋白，改善血流变，降低血小板粘附和聚集等方面具有显著的疗效，分析其治疗早期DN的机制可能有以下几个方面：（1）降低血糖和糖化血红蛋白；（2）降低DN患者红细胞AR活性、提高SDH活性、减少红细胞内山梨醇积聚从而改善多元醇代谢；（3）调节脂质代谢；（4）改善DN患者血液凝、聚、浓、粘状态，抑制血小板的粘附聚集，从而改善肾脏微循环，保护肾功能。

Results Six compounds were obtained and their structures were identified as phytol, 7-hydroxycalamenene, daphnetin, and daucosterol from the alcohol extract, D-glycero-D-galacto-heptitol and D-erythro-L-galacto-octitol from the water extract.

结果 从其乙醇提取物中分离得到植物醇、7-羟基去氢白菖烯、瑞香内酯、胡萝卜苷；从其水提取物中分离得到两个多元醇类化合物，分别是D-glycero-d-galacto-heptitol、D-erythro-L-galacto-octitol。

Sorbitol is the main polyalcohol synthesized in the leaves of apple trees and converted into sugars in the fruit.

山梨醇在苹果树的叶子里是主要的多元醇，进而在果实中转化为糖。

Based on the strict requirements of safely and fleetly deep drilling and reservoir protection to drilling fluid in drilling engineering, the modified polyalcohol anti-sloughing agent was developed and then a new alcohol drilling fluid was gained through screening other additives and optimizing formulation.

基于钻井工程中安全快速钻进及油气层保护对钻井液的严格要求，开发出了改性多元醇防塌剂，在此基础上通过优选其他处理剂和配方优化研制出了一种新型醇类钻井液。

Diabetic retinopathy is one of the most serious microvessel complications of diabetes,it is a main cosmopolitan blindness disease. In recent years, with the molecular biology development, the recognition of the mechanism of DR is more profound and consummate. Most researchers consider that hyperglycaemia, polyalcohol inositol metabolism abnormality, changes of hemorrheology, oxidative stress, inflammation/immune system activation, cytokines/growth factors expression or activity change and so on result in DRs onest and development.

糖尿病性视网膜病变(diabetic retinopathy， DR)是糖尿病最严重的微血管并发症之一，也是一种世界性的主要致盲眼病，近年来随着分子生物学方面的研究进展，对DR发病机制的认识进一步深入和完善，认为高血糖、多元醇肌醇代谢异常、血液流变学改变、氧化应激、炎症/免疫系统活化、细胞因子/生长因子表达或活性改变等导致DR的发生发展。

Saturated small molecules such as glycerine, triethanolamine, saturated water-soluble macromolecules including corn starch and polyvinyl alcohol, and vinyl monomer are employed as modifiers for polymeric material surface.

本文首次利用Ce3+的紫外光敏特性，将其作为光催化引发剂，引发饱和小分子如单糖、多元醇，水溶性大分子如淀粉、聚乙烯醇，乙烯类单体如丙烯酸、丙烯酰胺、甲基丙烯酸甲酯等在聚合物基材表面的改性。

Gold and silver ; metal alkoxide ; low carbon multicomponent alcohol

从表2中可以看出，低温、氮气条件下，PU-1分解主要可辨别的组分为1，4丁二醇，（Fig.5a）中m/z71不能够辨别，（Fig.5b）显示了m/z71离子谱图，这些峰一定是聚合物多元醇热降解产生的低聚物。

A series of polyether based polyurethaneurea aqueous dispersions with well-defined hard segments were prepared by fractional steps with polyether polyol, 4,4'-diphenylmethane diisocyanate, dimethylolpropionic acid, 1,4-butanediol, isophorone diisocyanate and ethylenediamine.

以二苯基甲烷二异氰酸酯、二羟甲基丙酸、1，4-丁二醇、异佛尔酮二异氰酸酯和乙二胺为硬段，聚醚多元醇为软段，通过分子设计采用分步合成法，制备了具有规整硬段和良好分散性能的聚醚型聚氨酯脲水分散液。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
