Description

一种治疗糖尿病足的水溶性凝胶 技术领域
本发明涉及一种治疗糖尿病足的水溶性凝胶,属于天然生物大分子医疗器械领域。
技术背景
糖尿病足(diabetic foot)是糖尿病引起的足部瘙痒、皮肤溃疡、肢端坏疽等病变的总称.是与下肢远端神经异常和不同程度的周围血管病变相关的足部感染、溃疡和深层组织破坏(根据WHO的定义)。是糖尿病患者严重的并发症,严重影响病人的生活质量,糖尿病足发病机理复杂,和一般组织创面有所不同,在高糖浓度下,组织愈合相对困难,再加上神经病变,失去神经营养作用,血管周围病变,局部循环受限,更加不利于伤口愈合。
目前的治疗一般有控制血糖、清创、抗感染,对于后期严重行介入、手术截肢等治疗,但是由于治疗效果欠佳,费用较大,给病人带来不小痛苦,因此对于糖尿病足治疗新方法研究一直不断探索。
糖尿病足根据致病主要机理分为三型:单纯溃疡性、神经源性、血管源性。临床治疗根据其不同类型区别治疗,但是无论何种治疗一项重要机理就是利用皮肤自我修复能力进行诱导真皮再生,在诱导过程中,新毛细血管形成及成纤维细胞、上皮细胞增生修复起主要作用,而在新生细胞周围有大量胶原纤维,并有资料表明:胶原蛋白具有诱导真皮组织修复作用。但是一般外源胶原蛋白价格较为昂贵,不能广泛推广,外用胶原蛋白如何被体内吸收也是制约胶原蛋白外用的因素,从异体提取胶原蛋白还存在抗原-抗体反应风险。
生物低抗原性活性胶原(Ⅰ型)是天然生物大分子,是从检验检疫合格的鲜动物皮(例如:驴皮,牛皮,猪皮等)中精制提取的。中国专利ZL 201010176321.9公开了一种从驴皮中提取活性胶原(Ⅰ型)的方法,但并未对其应用展开研究。因此,对于活性胶原(Ⅰ型)如何应用仍处于摸索阶段。
发明内容
针对上述技术问题,本发明目的在于提供一种解决糖尿病足治疗的新的方式,诱导皮肤再生的外用胶原蛋白,使皮肤愈合时间明显缩短,并减少瘢痕形成,尽可能接近皮肤原有组织结构,减少糖尿病足的发生,并且价格低廉、病人痛苦小、无毒副作用。
本发明的上述目的是通过如下技术方案实现的:一种治疗糖尿病足的水溶性凝胶,包括:
Figure PCTCN2015082037-appb-000001
Figure PCTCN2015082037-appb-000002
在本发明中,上述生物低抗原性活性胶原(Ⅰ型)是通过从新鲜的动物皮(例如:驴皮,牛皮,猪皮等)中提取得到的胶原,具体方法可以采用如CN201010176321.9和CN201473478U中所述的方法。采用该方法得到的上述生物低抗原性活性胶原(Ⅰ型)原液是一种白色,丝状的无端肽,其中生物低抗原性活性胶原(Ⅰ型)含量可以达到99.5%以上。经发明人研究发现,该低抗原性活性胶原(Ⅰ型)保持三股螺旋的空间结构未受破坏,相对分子质量约300KD,具有生物活性;并且具有低抗原性的特点。研究还发现,该低抗原性活性胶原(Ⅰ型)分子量和结构与人体皮肤及结缔组织相同,具有同源性和相容性;并且其中中性条件下能够与水以任意比例互溶,在人体体温下,能够分解成多肽,单肽,又在其它酶的作用下能够分解成氨基酸,因而具有很强的水溶性和降解性。
上述稀释液是通过将提取得到的原液以一定比例稀释后得到的。具体而言,可以采用去离子水进行稀释,使得其中生物低抗原性活性胶原(Ⅰ型)的浓度在0.1%-0.5%。上述浓度计算可参考CN200610021100.8中的方法。在本发明中,生物低抗原性活性胶原(Ⅰ型)稀释液用量是根据生物低抗原性活性胶原(Ⅰ型)的浓度来确定的,具体而言,优选其浓度在0.3%-0.5%。
在本发明中,上述滋润剂中起到滋润伤口的作用,其包括但不限于是甘油;其用量优选4-4.5重量份。
在本发明中,上述杀菌剂起到抑制细菌生长的作用,其包括但不限于是尼泊金甲酯,尼泊金丙酯;其用量优选0.1-0.5重量份,更优选0.1-0.2重量份。
在本发明中,上述辅料起到在施用时,在伤口表面形成一层水溶性皮脂膜,使得伤口与外界环境隔绝,防止伤口感染,以及防止紫外线的作用,其包括但不限于水溶性硅油,例如可以是DC193;其用量优选0.1-0.8重量份,更优选0.2-0.6重量份。
在本发明的一个具体实例中,上述水溶性凝胶包括如下组分:

在本发明另一个具体实例中,上述水溶性凝胶包括如下组分:
Figure PCTCN2015082037-appb-000005
本发明的另一目的是提供一种上述水溶性凝胶的制备方法,包括如下步骤:
1)将生物低抗原性活性胶原(Ⅰ型)原液用水稀释;
2)将滋润剂和杀菌剂与步骤1得到的稀释液混合搅拌;
3)过滤;
4)将辅料与步骤3得到的物料混合,搅拌均匀。
在上述制备方法中,应在无菌环境下进行。
本发明的另一目的是提供一种上述水溶性凝胶在制备治疗糖尿病足的药物中的应用。
本发明的有益效果在于:赋予天然大分子活性胶原(Ⅰ型)具有的生物信息,诱导机体组织的微神经,微血管的再生修复,以达到机体恢复的目的。
