5  异丙酚（Propofol,丙泊酚,disoprofol）   异丙酚是一种新型静脉麻醉药，因具有起效快、时效短、苏醒迅速的优点，在临床广泛应用。其在发挥麻醉作用的同时，可使血糖升高，该作用对糖尿病人尤为明显，但停药后血糖迅速降至用药前水平。虽然该药升血糖作用持续时间短，但糖尿病人因自身糖代谢异常加之异丙酚的升血糖作用，血糖升高幅度大于非糖尿病人，所以应避免大剂量持续输入，从而减轻其升血糖作用[20]。异丙酚对血糖升高作用机制尚不明确。   6  其它   如糖皮质激素、甲碘胺、甲状腺素、甲状腺球蛋白、肾上腺素、烟酸及其衍生物、吩噻嗪类药物、促肾上腺皮质激素、雌激素与黄体酮样衍生物、双香豆素、去甲基麻黄碱等药物，均有增高血糖浓度的作用，使用时应注意监测血糖，避免引起高血糖或糖尿。   7  结语   正常水平的血糖对于人体各组织器官的生理功能是极其重要的。上述药物虽非糖类，但用药后均可不同程度的引起糖代谢异常，导致血糖升高。特别是长期应用时，可引起血糖持续增高，引发由高血糖所致的高血浆渗透压、渗透性利尿、毛细血管扩张、通透性增加、周围循环衰竭、血粘滞度升高、脑缺氧、脑水肿等。因而在使用这些药物期间应当定期监测血糖，避免引起高血糖。尤其是对糖尿病患者，多种药物所致的血糖升高作用比非糖尿病人更明显。加之糖尿病人本身就易出现血糖异常，因此他们更应慎重应用上述药物

Grafts the Chinese hawthorn isoflavone extraction process and the oxidation resistance research Biology and food science institute 2003 level of food sciences and project specialty Abstract: This article introduced in the Chinese hawthorn main nutrient content and the Chinese hawthorn the isoflavone function characteristic, respectively and grafts the Chinese hawthorn take the ordinary Chinese hawthorn as a raw material, has analyzed the different extraction method and the isoflavone extraction rate relations, and to grafted the Chinese hawthorn isoflavone the oxidation resistance function effect to carry on the analysis. Uses the mellow formulation, the water formulation and the ethyl acetate law three extraction method, separately and grafts the Chinese hawthorn juice extraction isoflavone to the ordinary Chinese hawthorn juice, through to the respective extraction rate's comparison and analysis knowing, uses the ethyl alcohol law to withdraw the isoflavone content to be high, and grafts in the Chinese hawthorn the isoflavone content slightly to be higher than the ordinary Chinese hawthorn isoflavone. After the single factor experiment analysis, seeks for the material fluid compared to, the ethyl alcohol density, the extraction temperature and the time and so on four extraction condition suitable parameter, thus had determined L9 (34) the orthogonal test each influencing factor's three levels, screen the material fluid compared to are 1:10, ethyl alcohol density are 85%, extraction temperature for 50℃, withdraw 1 hour for the extraction method optimum condition; Obtains the isoflavone density take the Kudzu root element as the standard through the ultraviolet spectrophotometric method, thus calculates obtains grafts the Chinese hawthorn juice isoflavone extraction rate is . Uses the color to respond and the paper chromatographic analysis law separately to withdraws the flavanone class material to carry on the appraisal. Through to joins the Chinese hawthorn juice, the sorbic acid potassium and does not have the antiseptic three kind of yogurt oxidation resistance abilities to carry on the experiment, finally indicated that the Chinese hawthorn juice yogurt's peroxide value is , is three product minimum values. In the Chinese hawthorn fruit includes the rich nutrient content and the pharmacology active constituent, is the depth the health foods which is liked the people, at present has become has the high research value and the development potential resources. Key words: Grafts the Chinese hawthorn; Isoflavone; Orthogonal test; Oxidation resistance
