Description
技术领域
本发明涉及中药领域,具体是一种治疗糖尿病足溃疡的内服中药颗粒制剂及制备方法。
背景技术
糖尿病足是糖尿病最严重的慢性并发症,糖尿病足一旦形成,病情就可能进行性发展,以致难以控制,引发坏疽,终致截肢甚或死亡。每年的截肢患者中约50%是糖尿病患者,而后者85%以上是由足部溃疡恶化造成深部感染或坏疽所致。美国每年糖尿病足花费400亿美元,占糖尿病治疗费用的1/5,且费用和所占的比重快速上升;在我国以省会城市为例,糖尿病患者人均医疗费用为:无并发症患者2000元/年,有并发症患者达到14000元/年。天津医科大学总医院统计结果显示:糖尿病足占门诊2.24%,住院的8.57%,截肢率17.31%。
西医学认为糖尿病足发病病因包括:神经病变、血管病变、循环障碍、免疫障碍、皮肤中促进皮肤生长的胰岛素生长因子-1(IGF-1)减少等,其中主要是神经和血管病变。大多数糖尿病足病情复杂而严重,治疗时需要多学科配合,内科治疗方面控制血糖、控制感染、选择敏感抗生素治疗、改善血液循环、营养神经治疗、改善缺血等;外科治疗方面包括局部清创、血管重建手术、介入手术、自体皮瓣移植、截肢(趾)术等;近年来兴起的干细胞移植治疗,虽然在降低截肢率方面取得了一定进展,但各个中心所应用方法不尽相同,疗效也有待于多中心的临床验证,推广应用有待于进一步研究和观察。
中医对于糖尿病足的病因归纳为以下几个方面:气阴两虚,脉络闭阻;燥热内结,瘀血阻络;湿热瘀毒,化腐成疽;正气不足,阴阳俱虚等,针对糖尿病足的中药研发很少,现有的中药制剂对于糖尿病足的疗效欠佳。
发明内容
本发明的目的在于提供一种治疗糖尿病足溃疡的内服中药颗粒制剂及制备方法,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:
