Abstract
本发明公开了一种中药组合物在制备缓解/治疗地中海贫血的药物中的应用。所述中药组合物包括当归、黄芪、阿胶、益母草和陈皮。该组方能够改善β地中海贫血小鼠的血液学表型,提高红细胞数、血红蛋白含量和红细胞压积,降低血清铁和肝脏铁含量;对地中海贫血有明显的缓解/治疗作用,本发明既拓宽了该组分的适应症范围,也为地中海贫血的缓解/治疗提供了一种新的中药组方选择,对地中海贫血的缓解/治疗具有明显的应用价值。
Description
技术领域
本发明属于生物医药技术领域。更具体地,涉及一种中药组合物在防治地中海贫血中的应用。
背景技术
贫血(anemia)是指人体外周血红细胞容量减少,低于正常范围下限的一种常见的临床症状。贫血的分类及诱因比较复杂。基于不同的临床特点,贫血有不同的分类。如:按贫血进展速度分急、慢性贫血;按红细胞形态分大细胞性贫血、正常细胞性贫血和小细胞低色素性贫血;按血红蛋白浓度分轻度、中度、重度和极重度贫血;按骨髓红系增生情况分增生性贫血(如溶血性贫血、缺铁性贫血、巨幼细胞贫血等)和增生低下性贫血(如再生障碍性贫血)。临床上常从贫血发病的机制和病因分类:1.红细胞生成减少性贫血:(1)造血干细胞异常所致贫血:再生障碍性贫血、纯红细胞再生障碍贫血(PRCA)、先天性红细胞生成异常性贫血(CDA)、造血系统恶性克隆性疾病;(2)造血微环境异常所致贫血:骨髓基质和基质细胞受损所致贫血、造血调节因子水平异常所致贫血、淋巴细胞功能亢进贫血、造血细胞凋亡亢进贫血;(3)造血原料不足或利用障碍所致贫血:叶酸或维生素B12缺乏或利用障碍所致贫血、缺铁和铁利用障碍性贫血。2.红细胞破坏过多性贫血:红细胞自身异常导致的贫血、红细胞周围环境异常导致的贫血。3.失血性贫血等。
其中,地中海贫血,又称珠蛋白生成障碍性贫血、海洋性贫血,是一种遗传性溶血性贫血疾病。由于遗传的基因缺陷致使血红蛋白中一种或一种以上珠蛋白链合成缺如或不足所导致的贫血或病理状态,与其他因素诱导的贫血相比具有明显的特殊性。本病广泛分布于世界许多地区,东南亚为高发区之一。
目前地中海贫血的重要治疗方法是输血和去铁。中医药及植物来源药用材料是我国的一大瑰宝,在人体健康与疾病的预防、缓解与治疗方面,相比西医具有明显的优势。申请人公司的一种由当归、黄芪、阿胶、益母草和陈皮组成的中药方(ZL200610011863.4),对产后贫血具有明显的改善作用。但是该中药方对地中海贫血等其他类型的贫血是否仍有作用以及效果如何,尚未有相关研究探索。
发明内容
本发明旨在提供一种能够缓解/治疗地中海贫血的中药方,也拓展了该组方的应用范围。
本发明的目的是提供一种中药组合物在制备缓解/治疗地中海贫血中的药物中的应用。
本发明上述目的通过以下技术方案实现:
一种中药组合物在制备缓解/治疗地中海贫血的药物中的应用,以及在制备缓解/治疗地中海贫血的药物中的应用,所述中药组合物包括当归、黄芪、阿胶、益母草和陈皮。
所述地中海贫血包括α型地中海贫血、β型地中海贫血等常见地中海贫血类型。
另外,优选地,所述中药组合物包括当归20-500份、黄芪20-500份、阿胶10-300份、益母草20-500份、陈皮1-100份。
更优选地,所述中药组合物包括当归80-120份、黄芪80-120份、阿胶24-36份、益母草120-180份、陈皮2.4-3.6份。
更优选地,所述中药组合物包括当归100份、黄芪100份、阿胶30份、益母草150份、陈皮3份。
另外,上述中药组合物的制备方法包括步骤如下:
(1)将黄芪、益母草加3-10倍量水煎煮1-5次,每次1-3小时,合并煎液,滤过,滤液浓缩至相对密度为1.10-1.25(50-90℃)的清膏,备用;
(2)当归、陈皮粉碎成粗粉,用3-8倍量40-95%的乙醇作溶剂,浸渍8-90h后渗漉,收集渗漉液,渗漉液回收乙醇并浓缩至相对密度为1.10-1.25(50-90℃)的清膏,备用;
(3)将阿胶溶于上述黄芪、益母草清膏中,再加入当归、陈皮清膏,混合即可。
更优选地,步骤(1)是将黄芪、益母草第一次加4.8-6倍量水煎煮2小时滤出煎液后,第二次加3.2-4.8倍量水煎煮1.5小时,滤出煎液,合并煎液,滤过,滤液浓缩至相对密度为1.10-1.15(60-70℃)的清膏,备用。
更优选地,步骤(2)是将当归、陈皮粉碎成粗粉,用4-5倍量60-80%的乙醇作溶剂,浸渍40-60h后渗漉,收集渗漉液,渗漉液减压浓缩至相对密度为1.10-1.15(60-70℃)的清膏,备用。
本发明具有以下有益效果:
本发明研究显示,由当归、黄芪、阿胶、益母草和陈皮制成的中药对地中海贫血具有显著的缓解/治疗效果,无副作用。既拓宽了该组分的适应症范围,也为地中海贫血的缓解/治疗提供了一种新的中药组方选择。

(3)动物处理
β654地中海贫血小鼠普通饲料喂养四周后,根据体重随机分成对照组和实验组,每组6只。对照组喂养普通饲料,实验组在对照组普通饲料中添加1%实施例1所得中药,连续喂养8周。
(4)指标检测
使用1%戊巴比妥钠对小鼠进行麻醉,采血并分离血清,采集肝脏组织。
血液学指标检测:采用迈瑞兽用全自动血液细胞分析仪(型号:BC-2800vet)检测小鼠血液学指标,包括红细胞数目、血红蛋白、红细胞压积和平均红细胞体积。
铁相关指标检测:采用南京建成生物工程研究所的测试盒(货号:A039-1-1和A039-2-1)进行小鼠血清铁和肝脏铁含量检测。
(5)统计学方法
使用SPSS21.0进行统计学分析,计量资料以X±SD表示,组间比较采用Mann-Whitney U检验,P<0.05为差异有统计学意义。*p<0.05,**p<0.01。
2、实验结果
结果显示,实验组的红细胞数、血红蛋白含量和红细胞压积明显高于对照组(表1、表2、表3),表明本发明中药组方可以改善β地中海贫血小鼠的血液学表型;此外,实验组的红细胞体积比对照组的要小(表4),实验组小鼠血清铁和肝脏铁含量明显低于对照组(表5),表明本发明的中药组方可限制红细胞铁的吸收。
