Abstract

本发明提供绿原酸在制备治疗骨硬化病的药物中的用途。绿原酸可以有效治疗骨硬化病,治疗效果优于阳性药物强的松与舒经活血片的联合用药,并且副作用较小。

Description

绿原酸在制备治疗骨硬化病的药物中的用途 技术领域
本发明涉及绿原酸在制备治疗骨硬化病的药物中的用途。
背景技术
骨硬化病,又称大理石骨症,或称原发性脆骨硬化症,是一种少见的全身性骨结构发育异常的先天性疾病,颅骨为好发部位之一。骨质极为密,并失去原来的结构,犹如大理石,但骨脆性增加易发生骨折。尚可以伴贫血、眼萎缩及耳聋等情况。一般认为,绝大多数病人在出生前即已开始有病变。根据临床表现分为恶性(幼儿型)及良性(成人型)两种,前者常为死产或出生后死于贫血,预后差。石骨症的发病原因尚不明确,可能与骨吸收异常有关,致使钙盐过量沉积于骨内,外观呈大理石或象牙样,脆性增加。本病有家族史,多见于近亲结婚的子女中。
目前,骨硬化病的有效治疗途径只有造血干细胞移植,但是找到造血干细胞的移植供者却非常困难。基于治疗的难度和发病机理的不明确,通常情况下均采用联合给药对症治疗的治疗方案,如用强的松治疗贫血,舒经活血片治疗骨损伤,但是治疗效果不佳,且毒副作用大,如,强的松会引起股骨头坏死,应激性溃疡,类固醇性高血糖,容易合并感染及精神异常等等。
未见绿原酸治疗骨硬化病的报道。
发明内容
本发明的技术方案是提供了绿原酸的新用途。
本发明提供了绿原酸在制备治疗骨硬化病的药物中的用途。
其中,所述的药物是以有效量的绿原酸为活性成分,加上药学上可接受的辅料或者辅助性成分制备而成的制剂。
其中,所述的药物制剂中每制剂单位含有绿原酸1~1000mg。
其中,所述的药物制剂中绿原酸的使用剂量为1~100mg/kg。
其中,所述的药剂是口服制剂或者注射剂。
综上,本发明绿原酸可以有效治疗骨硬化病,治疗效果比阳性药物强的松与舒经活血片的联合用药还要好,而且其已经被证明是一种安全的药物,副作用小,临床应用前景良好。
显然,根据本发明的上述内容,按照本领域的普通技术知识和惯用手段,在不脱离本发明上述基本技术思想前提下,还可以做出其它多种形式的修改、 替换或变更。

具体实施方式
实施例1:绿原酸治疗骨硬化病体内药效学试验研究
1.实验材料
1.1动物
骨硬化病BALB/C小鼠50只。
本实施例中所使用的动物模型,是直接购买的患有骨硬化症BALB/C小鼠(该小鼠也是国内外骨硬化病基础研究的常用模型)。该小鼠模型由于病鼠骨质生长异常,骨质硬,骨髓腔消失,所有骨骼都硬化,并伴有无齿症。这种鼠的病变的与人类硬骨病相似。
1.2实验药物及仪器
绿原酸,强的松(河北鑫银河化工有限公司),舒筋活血片(河南中杰药业有限责任公司),双蒸水,12孔无菌板,96孔无菌板,高倍显微镜,电子天平(十万分之一)。
2.实验方法
2.1实验动物分组及给药
骨硬化病属于罕见病,临床对其的治疗和研究都比较欠缺,国内外尚没有治疗骨硬化病的特效药,用药大多停留在对症治疗的层面上。本实验采用强的松和舒筋活血片联合用药的给药方案作为阳性对照组。按给药剂量:强的松(6mg/kg),舒筋活血片(1片/只)进行给药治疗。以普通BALB/C小鼠作为正常对照组。
将骨硬化病小鼠模型随机平均分为5组,分别命名为模型对照组(模型组,n=10)、强的松和舒筋活血片联合治疗组(联合治疗组,n=10)、绿原酸低剂量治疗组(L-LYS组,n=10)、绿原酸中剂量治疗组(M-LYS组,n=10)和绿原酸高剂量治疗组(H-LYS组,n=10),连同正常对照组(NC组,n=10),共6个实验组,共60只。具体分组及给药方式如表1所示:
表1.实验分组、给药方式及给药量(注:所有给药组的给药体积相同)
Figure PCTCN2015072415-appb-000001
2.2.检测指标和实验方法
2.2.1小鼠红细胞和血小板指标检测
采用尾静脉取血的方式对各组小鼠进行取血,之后对血中的红细胞和血小板指标等进行检测。
2.2.2小鼠外貌特征、生存率和肝脾重量的检测
对各组小鼠的外貌特征、体重变化等进行检测。实验结束后,处死小鼠,称取各组小鼠的肝脏和脾脏重量,计算肝、脾百分比(肝脏或脾脏重量/小鼠体重)。
2.2.3小鼠骨片吸收陷窝计数及吸收陷窝面积测定
①破骨细胞的分离
将上步解剖后的小鼠的四肢长骨进行分离,仔细清除附着于骨头表面的软组织和骨骺,骨干部分用PBS清洗后放入盛有15%199培养液(含10%小牛血清、5%胎牛血清、100μg/mL硫酸链霉素、100U/mL青霉素钠,pH7.2)的玻璃平皿中。用解剖刀将骨质内表面轻刮入培养液,再用圆头习惯反复吹打骨质碎片2min,静置30s后将上层细胞悬液(密度为1×106/mL)均匀接种于预置薄骨片的24孔培养板内。每孔分别加入破骨细胞悬液1mL及含血清的细胞培养液1mL,进行培养。
②骨片吸收陷窝技术及吸收陷窝面积测定
采用骨片吸收陷窝甲苯胺蓝染色光镜法100倍下计数各组骨片上的吸收陷窝数,进行记录和分析。
3.实验结果
3.1小鼠红细胞和血小板指标检测
小鼠的红细胞和血小板指标检测的结果显示,患有骨硬化病的模型组小鼠,其红细胞和血小板数显著降低,其与正常对照组相比,具有非常显著性差异(p<0.01)。联合给药组的小鼠的红细胞和血小板数较模型组相比有了明显升高,二者之间有非常显著性差异(p<0.01),但与正常对照组相比,尚有显著性差异(p<0.05)。绿原酸治疗组的小鼠,其血细胞和血小板数也有显著升高,与模型组相比,有非常显著性差异(p<0.01),且中、高剂量的 绿原酸给药组,已经能使红细胞和血小板数达到正常值,与正常对照组之间没有统计学差异(p>0.05)。不同剂量绿原酸给药组小鼠的红细胞和血小板数,均高于联合给药组,各组数据分别与联合给药组相比后显示有显著性差异(p<0.05)。

3.2小鼠外貌特征、体重、生存率和肝、脾重量百分比的检测
治疗60天后,观察小鼠的各种外貌和体态特征,结果发现:(1)模型组的小鼠死亡严重,10只中有7只死亡,且存活的小鼠骨头僵直,肌肉也大面积僵硬,且伴随间隔性抽搐。(2)联合给药治疗组的小鼠,相对死亡率较低,有4只小鼠死亡,且小鼠的活动基本正常,骨头僵直程度较弱,面部肌肉僵硬较严重,且也观察到小鼠有抽搐现象。(3)绿原酸治疗的小鼠中,其死亡率明显降低,低剂量绿原酸治疗组的小鼠死亡1只,且小鼠活动基本正常,骨头也未见明显僵直,只有两只小鼠的面部有肌肉僵硬的现象。而中剂量绿原酸治疗组的小鼠未见死亡,且活动正常,骨头未僵直,肌肉也未僵硬。高剂量的绿原酸治疗组的小鼠死亡一只,其活动基本正常,小鼠骨头未见明显僵直,面部正常。
肝、脾脏肿大,是骨硬化病的临床表现之一,对各组的小鼠解剖后的肝脏和脾脏进行称重后得到肝、脾重量百分比指数,结果显示,与正常组相比,模型组的小鼠肝、脾重量百分比明显升高,提示其肝、脾肿大程度较大。而联合给药治疗的小鼠,其肝、脾重量百分比均有明显下降,与模型组之间有显著性差异(p<0.05)。而绿原酸治疗的各组小鼠,其肝、脾脏的重量百分比,也有较为明显的下降,与模型组之间存在显著性差异(p<0.05)。所有测定结果如表3所示。

3.3小鼠骨片吸收陷窝计数及吸收陷窝面积测定
骨硬化病的根本是由于破骨细胞性骨吸收严重障碍,本部分实验的结果显示:(1)骨硬化病模型组的小鼠,与正常对照组的小鼠相比,其骨片吸收窝陷数目和吸收窝陷面积非常少,提示其破骨细胞性骨吸收发生严重障碍。(2)联合给药治疗组的小鼠,其骨片吸收陷窝数无明显升高,与模型组之间无统计学差异(p>0.05)。(3)高、中、低剂量绿原酸给药组的小鼠,其吸收窝陷面积均有明显的升高,各组的增加幅度有所不同,分别与模型组相比,均有非常显著性差异(p<0.01)。高、中剂量绿原酸治疗组的小鼠,其骨片吸收陷窝计数和吸收陷窝面积的测定结果,与正常对照组之间没有统计学差异(p>0.05)。测定结果显示,绿原酸能够显著增加骨片吸收陷窝计数及吸收陷窝面积,促进破骨细胞性骨吸收。而联合给药组没有表现出相应的实验结果。所有测定结果如表4所示。

本实施例以骨硬化的BALB/C小鼠作为实验模型,鉴于国内外尚没有治疗骨硬化病的特效药,故而结合临床的实际治疗方案,采用强的松和舒筋活血片联合给药的方法来作为阳性对照治疗骨硬化病小鼠。通过各组小鼠的外貌体征、肝脏和脾脏重量指数、生存率、红细胞、血小板、骨吸收窝陷数目和面积的测定,结果显示,绿原酸治疗后的骨硬化病小鼠,其生存状况良好,外貌体征等较为正常,肝、脾脏重量趋于正常化,且红细胞和血小板有了显著提高,另外,破骨细胞骨吸收窝陷数目和面积有了显著的提高,高、中、低剂量绿原酸治疗组的测定结果均高于强的松和舒筋活血片联合给药治疗组,提示绿原酸能够有效促进破骨细胞的骨性吸收,显著改善小鼠的红细胞和血小板数目,对骨硬化病的生存状况等都有非常明显的提高,表现出良好的药效。

1.实验材料
1.1动物
骨硬化病BALB/C小鼠30只。
本实施例中所使用的动物模型,是直接购买的患有骨硬化症BALB/C小鼠。该小鼠模型由于病鼠骨质生长异常,骨质硬,骨髓腔消失,所有骨骼都硬化,并伴有无齿症。这种鼠的病变的与人类硬骨病相似。
1.2实验药物及仪器
绿原酸,强的松(河北鑫银河化工有限公司),舒筋活血片(河南中杰药业有限责任公司),Ⅱ型碳酸酐酶ELISA检测试剂盒,PCR仪,RNA提取试剂盒,cDNA链合成试剂盒,双蒸水,12孔和96孔板,酶标仪,电子天平。
2.实验方法
2.1实验动物分组及给药
骨硬化病属于罕见病,临床对其的治疗和研究都比较欠缺,国内外尚没有治疗骨硬化病的特效药,用药大多停留在对症治疗的层面上。本实验采用强的松和舒筋活血片联合用药的方式作为阳性对照组。按给药剂量:强的松(6mg/kg),舒筋活血片(1片/只)进行给药治疗。以普通BALB/C小鼠作为正常对照组。
将骨硬化病小鼠模型随机平均分为3组,分别命名为模型对照组(模型组,n=10)、强的松和舒筋活血片联合治疗组(联合治疗组,n=10)和绿原酸治疗组(LYS组,n=10),连同正常对照组(n=10),共4个实验组,共40只。具体分组及给药方式如表5所示:

2.2检测实验
2.2.1RT-PCR法检测各组小鼠骨细胞中的CA2基因的表达情况。
(1)破骨细胞总mRNA的提取
①破骨细胞的分离:实验终止后,将小鼠经75%酒精浸泡消毒5min,拉颈处死后分离四肢长骨,仔细清楚附着于骨头表面的软组织和骨骺,骨干部分用PBS清洗后放入盛有15%199培养液(含10%小牛血清、5%胎牛血清、100μg/mL硫酸链霉素、100U/mL青霉素钠,pH7.2)的玻璃平皿中。用解剖刀将骨质内表面轻刮入培养液,再用圆头习惯反复捶打骨质碎片2min,静置30s后收集上层的细胞悬液,所有实验组均分成两份A和B,备用。
②将上述细胞悬液A进行离心,收集破骨细胞,分别编号命名,向每份破骨中加入350μl的预先加有β-巯基乙醇的裂解液RL,静置5min。
③将上述液体在12,000rpm/min的条件下离心3min,小心吸取上清液使用;
④向上清液中缓慢加入0.5倍体积的无水乙醇,反复吹打,直至混合均匀后转移至吸附柱CR3中,12,000rpm离心2min,弃去废液,留吸附柱;
⑤加入去蛋白液RW1至吸附柱中,去除蛋白,之后离心1min,弃去废液;
⑥向吸附柱CR3中加入DNase I工作液,降解其中的DNA;
⑦.用去蛋白液和漂洗液分别清洗吸附柱后,将吸附柱放于收集管中,开启通风,充分挥干柱子上的残留液体;
⑧向吸附柱中加入40μlRNase free ddH2O,放置2min后,12,000rpm离心2min,即得mRNA样品;
(2)mRNA的逆转录
利用cDNA第一链合成试剂盒和上述提取得到的RNA溶液合成对应的第一链cDNA。具体逆转录过程按照说明书操作,简述如下:
1.取200μl的无酶离心管置于冰浴上,并于其中加入下列溶液:RNA模板5mL,Oligo(dT)2Ml,Super Pure dNTP2Ml,RNase-Free ddH2O5.5mL。
2.离心后,将装有上述液体的离心管放置于PCR仪中,70℃孵育5min后,简短收集液体后,迅速将其转移到冰上冷却2min后补加如下试剂:5×first strand buffer(含DTT)4mL,RNasin0.5mL,TIANScriptM-MLV(200U)1mL。
3.将离心管轻轻混匀并简短离心后,设置PCR仪42℃孵育50min,之后95℃加热5min。最后向得到的cDNA溶液中加入20ul RNase-Free ddH2O稀释至40ul,即得第一链cDNA。
4.将得到的产物仔细编号后置于-20℃条件下保存。
(3)RT-PCR定量
EvaGreen荧光染料与双链的DNA结合会产生很强的荧光,通过检测最终的荧光强度,我们可以得到反应生成DNA的总量。在试管中加入荧光染料、(1)(2)步中所合成的cDNA产物、CA2引物混合均匀后进行RT-PCR检测本体系使用RNase-free water代替cDNA products组为NTC对照。每个样品均设β-actin引物组为相对值,进行相对定量。
2.2.2各组小鼠破骨细胞中Ⅱ型碳酸酐酶的测定
取2.2.1(1)中所述的B组破骨细胞悬液,吹打均匀后,小心的于12孔板中进行孵育,24后进行试验。用BCA法进行蛋白定量后,利用Ⅱ型碳酸酐酶ELISA酶联免疫试剂盒进行后续试验,测定Ⅱ型碳酸酐酶活性。
3.实验结果
3.1各组小鼠骨细胞中的CA2基因的表达情况
CA2基因的检测结果显示,在正常组小鼠的破骨细胞中CA2的表达相对较高,而骨硬化病模型组的小鼠中,其破骨细胞中的CA2基因表达显著下调。在分别用联合给药及绿原酸治疗后,在联合给药组中,小鼠破骨细胞中的CA2基因没有明显的上升,其与模型组相比没有统计学差异(p>0.05),而绿原酸治疗的小鼠,能够显著的提高小鼠破骨细胞中CA2基因的表达,其与模型组及联合给药组相比,均有非常显著性的差异(**p<0.01,##p<0.01)。基因检测的实验结果如图1所示。
3.2各组小鼠破骨细胞中Ⅱ型碳酸酐酶的测定结果
Ⅱ型碳酸酐酶的检测结果显示,骨硬化病模型小鼠的破骨细胞中Ⅱ型碳酸酐酶的含量相比于正常对照组,显著下降,而Ⅱ型碳酸酐酶是破骨细胞骨吸收的关键促进酶,此种下降显示在骨硬化病的小鼠模型中破骨细胞的骨吸收能力严重不足。其Ⅱ型碳酸酐酶含量与对照组相比,具有非常显著性的差异(**p<0.01)。在经过联合给药治疗后,小鼠破骨细胞中的Ⅱ型碳酸酐酶含量没有明显变化,其与模型组之间没有统计学的差异(p>0.05)。而绿原酸治疗的小鼠中,其破骨细胞中的Ⅱ型碳酸酐酶含量有了非常显著的上调,与联合给药组之间具有非常显著性的差异(△△p<0.01),但与正常对照组相比,其值尚有显著性差异(*p<0.05)。
结果显示,绿原酸能高效的促进Ⅱ型碳酸酐酶的表达,从而促进破骨细胞性的骨吸收。具体的实验结果如图2所示。
4.统计学处理
连续型变量形式的实验数据以

表示,2组数据间的比较用两样本t检验。采用SPSS13.0统计软件,P<0.05为有统计学意义。
5.结论
本实施例中,采用患有骨硬化病的BALB/C小鼠作为模型动物,以联合给予强的松和舒筋活血片作为阳性治疗对照组。分别测定了各组小鼠破骨细胞中的CA2基因及对应的Ⅱ型碳酸酐酶的表达情况。结果显示,与联合给药组相比,绿原酸能够有效的上调小鼠破骨细胞中CA2基因的表达,同时促进其对应Ⅱ型碳酸酐酶的含量提升。Ⅱ型碳酸酐酶主要功能是促进破骨细胞的骨性吸收,对其的激活能够显著的改善因破骨细胞吸收不良而导致的骨质硬化症。综上,绿原酸能够显著的激活Ⅱ型碳酸酐酶活性,对骨硬化病具有一定的治疗作用。
