Abstract
本发明公开了鸡血藤水提物、中药组合物用于治疗慢性皮肤溃疡的应用及口服制剂,属于中医药技术领域。本发明的中药组合物以生黄芪、茯苓、白术、苍术、山茱萸、怀牛膝、肉桂、鸡血藤、首乌藤和鹿茸等为原料,并通过对上述各原料特定用量的限定,使得各原料之间配伍科学合理,各原料功效成分相辅相成,相得益彰,所得到的中药组合物能够促进慢性皮肤创面(免疫抑制小鼠)创面愈合,且效果优于鸡血藤水提物和鸡血藤有效部位,对于多种原因引起的慢性皮肤溃疡具有良好的治疗效果。
Description
技术领域
本发明属于中医药技术领域,涉及一种用于治疗慢性皮肤溃疡的中药组合物及基于其的口服制剂和制备方法,具体涉及鸡血藤水提物及基于其的中药组合物用于治疗慢性皮肤溃疡口服制剂的制药应用。
背景技术
慢性皮肤溃疡即指慢性创面,国际伤口愈合学会将其定义为无法通过正常有序而及时的修复过程达到解剖和功能上的完整状态的伤口。随着人口老龄化及糖尿病和肥胖的不断增多导致了慢性创面的发病率的升高。慢性皮肤溃疡是糖尿病、周围血管病、微生物感染、放疗等常见的并发症,是外科常见病及多发病,因其迁延不愈、易复发等特点,一直是外科领域颇为棘手的难题。
目前临床上针对创面主要采用清创、植皮等外科治疗方法,但是临床疗效并不十分理想。特别是,糖尿病足溃疡(DFU)迁延日久,造成骨髓干细胞的数量减少及干细胞动员功能受损,国内外众多学者都在积极寻求有效的治疗药物和方法。
鸡血藤,中药名,为豆科植物密花豆Spatholobussuberectus Dunn的干燥藤茎,分布于广东、广西、云南等地。因其具有活血补血,舒筋活络之功效,有报道将其与其他中药组合后用于治疗皮肤创伤,但未有记载将该药物用于慢性皮肤溃疡的报道,以及未有明确该药物的确切功效发生部位及明确有效剂量。
发明内容
为了克服上述现有技术的缺点,本发明的目的在于提供一种用于治疗慢性皮肤溃疡的中药组合物及基于其的口服制剂和制备方法。
为了达到上述目的,本发明采用以下技术方案予以实现:
本发明公开了鸡血藤水提物在制备用于治疗慢性皮肤溃疡的药物中的应用,所述鸡血藤水提物的制备方法如下:
以质量份数计,取鸡血藤20~40份,加8~10倍量纯水,浸泡20~40分钟,大火煎煮沸腾后改为小火,小火持续煎煮40~60分钟,过滤获得药液和药渣;药渣再加5~8倍量纯水,继续进行大火煎煮直至沸腾,小火继续煎煮20~40分钟,再次过滤获得二次药液;将两次获得的药液合并后浓缩,制得鸡血藤水提物。
优选地,所述的药物采用中剂量浓度的鸡血藤水提物制成;其中,高剂量浓度为药液浓缩至浓度为0.772g/mL,中剂量浓度和低剂量浓度分别是高剂量浓度的1/2和1/4。
进一步优选地,所述的药物的给药量为:高剂量60g/天/70kg、中剂量30g/天/70kg、低剂量15g/天/70kg。

将两次获得的药液合并后浓缩至终体积2.05g/mL。
与现有技术相比,本发明具有以下有益效果:
本发明公开了鸡血藤水提物能够制备用于治疗慢性皮肤溃疡的药物的应用,对于鸡血藤水提物经过实验验证,鸡血藤水提物高、中、低剂量(0.772g/mL、0.386g/mL、0.193g/mL,相当于人60g/天/70kg、30g/天/70kg、15g/天/70kg),对于小鼠中剂量促进创面愈合的效果优于低剂量和高剂量,这是本发明的创新点之一。
本发明公开的用于治疗慢性皮肤溃疡的中药组合物,主要以生黄芪、茯苓、白术、苍术、山茱萸、怀牛膝、肉桂、鸡血藤、首乌藤和鹿茸等为原料,其中鸡血藤养血活血,具有促进骨髓造血,升高外周血白细胞的功能,与生黄芪、鹿茸共为君药,增加了健脾益气,补肾益阳的功效,有效改善慢性皮肤溃疡脾肾阳虚,气血不足的状态;茯苓、首乌藤和肉桂作为臣药,助君药健脾益气,补肾回阳;白术、苍术和山茱萸作为佐药,健脾燥湿,补益脾肾;慢性皮肤溃疡常发生于下肢,故选择怀牛膝作为使药,引气血下行,改善下肢慢性皮肤溃疡创周的血液循环。
本发明通过对上述各原料特定用量的限定,使得各原料之间配伍科学合理,各原料功效成分相辅相成,相得益彰,所得到的中药组合物能够促进慢性皮肤创面(免疫抑制小鼠)创面愈合,且效果优于鸡血藤水提物和鸡血藤有效部位,对于多种原因引起的慢性皮肤溃疡具有良好的治疗效果。本发明的中药组合物制成的可以内服的中药制剂,区别于现有技术中关于创面愈合药物通常是外用制剂而言,也是本申请的一个创新点,通过中药内服健脾益肾,填精益髓,扶助正气,促进骨髓干细胞的增殖及动员,修复创面,促进创面愈合。

下面结合附图对本发明做进一步详细描述:
一、鸡血藤水提物的制备和药物入血成分分析
鸡血藤30份,加10倍量纯水(W/V),浸泡30分钟,大火煎煮沸腾后改为小火,小火持续煎煮60分钟,过滤获得药液和过滤药渣;药渣再加6倍量纯水(W/V),对过滤药渣继续进行大火煎煮直至沸腾,小火继续煎煮30分钟,再次过滤获得二次药液;将两次获得的药液合并后浓缩至高剂量浓度0.772g/m L,冷藏备用,鸡血藤水煎剂的中剂量和低剂量的生药浓度分别是高剂量浓度的1/2和1/4。
对于鸡血藤水提物来说,以人与小鼠剂量换算计算,鸡血藤水提物高、中、低剂量(0.772g/mL、0.386g/mL、0.193g/mL,相当于人60g/天/70kg、30g/天/70kg、15g/天/70kg)。
对鸡血藤水提物入血成分进行超高效液相色谱串联质谱技术(ultra-performance liquid chromatography combined with tandem mass spectrometry,UPLC–MS-MS)分析,结果如表1。
表1鸡血藤血清UPLC-MS色谱图中色谱峰测定数据及推断
二、中药内服方的制备和药物入血成分分析
具体药物如下:生黄芪30g、茯苓20g、白术15g、苍术15g、山茱萸15g、怀牛膝10g、肉桂5g、鸡血藤30g、首乌藤15g、鹿茸5g,
君药:生黄芪、鸡血藤、鹿茸,健脾益气,养血活血,补肾益阳;臣:茯苓、首乌藤、肉桂,健脾益气,补肾回阳;佐:白术、苍术、山茱萸,健脾益肾;使:怀牛膝,引气血下行。
制备方法:中药煎煮:按照传统中药煎煮方法,将10剂中药浸泡于水中30分钟,大火煎煮沸腾后,改为小火,持续60分钟后,过滤出药液,进行第二次煎煮,大火煎煮沸腾后,改为小火,30分钟后,再次过滤药液,将两次所得药液混合,继续浓缩,浓缩终体积为2.05g/mL。
对制得的中药内服方入血成分进行UPLC–MS-MS质谱分析,质谱结果如表2。
表2中药内服方血清UPLC-MS色谱图中色谱峰测定数据及推断
三、中药内服方对免疫抑制小鼠愈合迟缓性创面的影响
BALB/c小鼠制作创面前7天,肌肉注射氢化可的松0.5mg/0.1ml/d;空白组小鼠每日肌肉注射等体积生理盐水(0.1ml)。小鼠于实验时使用异氟烷吸入麻醉(空气流量500-700ml/min,吸入浓度3%),背部制备直径7毫米的圆形全厚皮切除伤口;单笼饲养,非空白组小鼠隔日肌肉注射氢化可的松0.25mg(0.05ml);空白组小鼠隔日肌肉注射等体积生理盐水(0.05ml),笼内放置棉絮丰容。
实验分组:空白组;模型组;阳性对照组;本发明的中药组合物组(以下简称中药内服方组);鸡血藤水提物高、中、低剂量组。空白组、模型组每日灌胃蒸馏水0.2mL,外用含50uL生理盐水的明胶敷料;阳性对照组每日灌胃蒸馏水0.2mL,外用含50uL成纤维细胞生长因子(basic fibroblast growth factor,bFGF,3.6μg/mL)的明胶敷料。中药内服方组每日灌胃中药内服方(本发明的)0.2mL,外用含50uL生理盐水的明胶敷料;鸡血藤水提物高、中、低剂量组,每日灌胃0.2mL,外用含50uL生理盐水的明胶敷料。灌胃每天一次,创面以一次性无菌敷料贴包扎,隔日换药。
结果参见图1和图2,可以看出:与模型组相比,在制作创面后7、14天,中药内服方组及鸡血藤水提物高中低剂量组,创面愈合率均升高,而且在鸡血藤水提物组中,中剂量组升高的趋势最为明显。在创面愈合时间方面,中药内服方组及鸡血藤水提物高中低剂量组,愈合天数较模型组明显缩短,其中中药内服方组及鸡血藤水提物中剂量组,缩短的趋势最为明显。结论:本发明的中药内服方和鸡血藤水提物均能促进免疫抑制小鼠愈合迟缓性创面愈合;鸡血藤水提物促进创面愈合的最佳浓度为中剂量。
参见图3,采用中药内服方及鸡血藤水提物干预免疫抑制小鼠愈合迟缓性创面,观察创面愈合,结果发现:中药内服方剂以及鸡血藤高、中、低剂量组均能提高小鼠创面的愈合率,缩短创面愈合的时间。
以上内容仅为说明本发明的技术思想,不能以此限定本发明的保护范围,凡是按照本发明提出的技术思想,在技术方案基础上所做的任何改动,均落入本发明权利要求书的保护范围之内。
