一种治疗糖尿病肾病的药物组合物及其制备方法和应用 技术领域
本发明涉及中药制药领域,具体地说,涉及一种治疗糖尿病肾病的药物组合物及其制 备方法和应用。 背景技术
糖尿病及其慢性并发症已严重影响人类健康和生活质量。近年来, 糖尿病发病人数呈 上升趋势。 全世界各年龄组的糖尿病发病率, 在 2000年约为 2. 8%, 到 2030年预计为 4. 4%。 患糖尿病人数将从 2000年的 1. 71亿增加到 2030年 3. 33亿。中国每年糖尿病的发病率在不断 上升, 患病人数仅次于印度, 居世界第二位。糖尿病及其慢性并发症的防治是当今面临的 重要课题。 糖尿病肾病(diabetic nephropathy, DN)是糖尿病的重要并发症之一, 在西方 国家已成为导致终末期肾衰竭的首位疾病。 2003年世界卫生组织资料显示, 如果不控制血 糖, 大约有 30%的 1型糖尿病患者和 25%〜40%的 2型糖尿病患者发展成为糖尿病肾病。 糖尿 病肾病发病隐匿, 早期不易被发现, 出现症状时肾脏的病变已经不可逆转。长年糖尿病导 致肾脏的滤过功能被破坏, 最初表现为微量白蛋白尿。 随着病程延长, 尿蛋白增加, 肾脏 排除血中毒素的能力逐渐减退, 最终发展为终末期肾病 (ESRD), 只能依靠血液透析或肾移 植来维持生命。因此迫切需要深入阐明糖尿病肾病的发病机制,丰富和完善 DN的防治措施。
桑白皮 (Cortex Mori)为桑科植物桑 ori/s alba L. 的干燥根皮, 性甘、 寒, 具有泻 肺平喘、 利水消肿的功能, 主治肺热喘咳、 水肿胀满尿少、 面目肌肤浮肿, 近年的药理学 研究表明桑白皮具有降血糖血压、 利尿、 镇咳平喘、 抗 HIV抗肿瘤等方面的活性。 自 20世 纪 70年代有学者从桑白皮中分离并证实了降血糖成分 1-脱氧野尻霉素
(1 - deoxynoj irimycin)和桑糖苷元 (Moran A)以来, 越来越多的学者投身于从桑白皮中寻 找新的降血糖成分, 从而开发出新的治疗糖尿病药物。桑白皮主要活性成分有黄酮、 生物 碱、 多糖和香豆素 (伞形花内酯、 东莨菪素)等, 有研究证明桑白皮中的黄酮、 生物碱和多 糖都具有一定的降血糖作用,其中生物碱的作用最强, 而桑白皮中的香豆素成分主要用作 利尿镇咳平喘, 目前尚没有将其用作糖尿病肾病的治疗的文献报道, 而据国内近年的研究 报道表明香豆素具有抗 HIV、 抗癌、 降压、 抗心律失常、 抗骨质疏松、 镇痛、 平喘及抗菌 等多方面生物学活性, 将香豆素用于糖尿病肾病的治疗是香豆素用于医药领域的新用途。 确认本 发明内容
