Description
技术领域
本发明属于眼科疾病治疗技术领域,涉及一种冰片联合神经营养因子组合物及应用,更具体地,涉及一种冰片联合神经营养因子组合物在视网膜变性损伤中的应用。
背景技术
视网膜变性损伤是一组严重的致盲性眼病,其中最常见的有年龄相关性黄斑变性(age-related macular degeneration,AMD)及视网膜色素变性(retinitis pigmentosa,RP)等,目前临床上对此类疾病尚缺乏行之有效的治疗手段。这类疾病的共同病理基础是视网膜神经元细胞不可逆性损伤,因此神经保护是防治视网膜变性损伤的关键。
神经营养因子是一类对神经元的发育、存活和凋亡起重要作用的蛋白质,其成员包括睫状神经营养因子(ciliary neurotrophic factor,CNTF),脑源性神经营养因子(brain-derived neurotrophic factor),神经生长因子(nerve growth factor,NGF),神经营养素家族(neurotrophin)和胶质细胞源性神营养因子(glia cell line-derivedneurotrophic factor,GDNF)。其中CNTF是神经营养因子家族中被研究最多的成员之一,CNTF对神经元、少突胶质细胞、肌细胞、骨细胞、脂肪细胞有营养性和调节活性。目前已在至少13种不同的动物模型中得到证实CNTF可以有效延缓RP进程。研究发现,在RP小鼠模型的玻璃体腔内注射CNTF能够有效延缓其光感受器细胞的凋亡,并且使其视锥、视杆细胞的功能得到显著的提高。另有研究表明,在视网膜变性鼠模型中由腺相关病毒介导的持续人睫状神经营养因子(human ciliary neurotrophic factor,hCNTF)分泌可以对其整个视网膜外层的视锥细胞发挥保护作用。一项随机、多中心、剂量-梯度变化的临床试验发现利用细胞包囊技术(encapsulated cell technology,ECT)在RP患者眼内持续提供CNTF可以显著延缓RP的病程进展甚至停止发展。不少研究证实CNTF对AMD亦有保护作用。CNTF治疗可以使AMD患者的视网膜厚度增加,可以保护患者的视力,有效延缓AMD的病程进展。但是,由于眼球解剖的特殊性,视网膜给药需要克服许多生物屏障,外源性神经营养因子很难到达视网膜,在上述研究中给药方式采取了玻璃体腔内注射、基因转染、玻璃体内药物细胞微囊移植技术,存在有手术操作难度较大,排斥反应、眼内感染、视网膜脱离等潜在风险,且预期治疗费用昂贵,使神经营养因子治疗眼后节尤其是视网膜疾病受到很大限制。比如CNTF相关专利(专利号:CN103800894B)仅用于眼前节疾病比如角膜损伤、神经性角膜炎的治疗,申请号为200510097985.5的专利研究的是CNTF的突变体在治疗肥胖症或与肥胖症相关的疾病及神经损伤相关疾病中的应用。
冰片(Borneol)是一味常用中药,味辛、苦,性凉,归心、脾、肺经,主内外障眼,治五痔,明目。近年来药理研究发现冰片有镇痛抗炎作用,并能抑制一些细菌生长,但是冰片的主要作用与其“通透”的药性有关。冰片可以增加生物膜屏障通透性,因而增加自身和大多数配伍药物的渗透量、渗透速率。研究发现冰片对亲水性及亲脂性化合物在角膜的渗透性均有促进作用,前者的作用更强,可以明显促进分子量小于4kDa的亲水性物质通过角膜,并且没有毒副作用;我们前期研究发现冰片可以增强六味地黄丸对碘酸钠诱导的视网膜变性模型的保护作用。但目前冰片多和其它中药组方用于结膜炎、角膜炎的治疗,没有用于视网膜疾病治疗。因此,研究冰片联合神经营养因子在保护视网膜变性损伤的应用尤为重要。
发明内容
针对上述背景技术提出的不足,本发明的目的是提供一种冰片联合神经营养因子组合物及应用,该组合物可用于视网膜变性损伤类疾病的治疗,包括原发性视网膜色素变性、年龄相关性黄斑变性、视杆视锥细胞营养不良、以及高眼压引起的视网膜神经节细胞损伤等的治疗。本发明的第二个目的是提供一种视网膜变性损伤类疾病的保护方式,即冰片联合神经营养因子的应用。本发明的第三个目的是提供一种冰片的新用途,即在治疗视网膜变性损伤中的应用。

进一步地,本发明还提供了一种冰片联合神经营养因子在治疗视网膜变性损伤中的应用。
进一步地,本发明还提供了一种冰片联合神经营养因子在制备治疗视网膜变性损伤的制品中的应用。
进一步地,所述的制品为包含药理有效浓度的冰片及神经营养因子的药物。
进一步地,所述的制品为包含药理有效浓度的冰片联合神经营养因子的滴眼剂或注射液。
进一步地,所述的滴眼剂中包括药理有效浓度的冰片的含量为滴眼剂的0.01-0.1%。
进一步地,所述的滴眼剂中包括药理有效浓度的神经营养因子的浓度为0.5-2μg/mL。

进一步地,所述的制品还包括聚氧乙烯氢化蓖麻油40、聚乙二醇400、磷酸缓冲盐溶液和1%CMC-Na凝胶中的一种或多种。
与现有技术相比,本发明的有益效果为:
(1)本发明首次将中药冰片与神经营养因子相结合组成药物配方,将传统的中医引经理论与现代靶向理论相结合,建立引经药为载体的眼部给药系统,发挥中药及西药各自优势,具体的将传统常用的眼病外用药冰片与具有明确神经保护作用的睫状神经营养因子(CNTF)相结合,制备保护视网膜神经细胞的滴眼剂,为防治视网膜变性类疾病提供新的药物选择。
(2)本发明实施例中使用滴眼剂方式给药,促进有效药物成分在视网膜的分布,配方中含有一定浓度的冰片,冰片具有促渗作用,本发明中冰片联合CNTF滴眼剂点眼后,视网膜中CNTF含量较单纯CNTF滴眼剂组明显增加。
(3)本发明中的药物具有良好的用药顺应性:首先,本专利以滴眼剂的剂型方式给药治疗眼底病变,与玻璃体腔注射、静脉给药、玻璃体内药物细胞微囊移植等方法相比安全性及便利程度明显增加,在临床应用中患者接受度高;另外,本制剂选择合适的增溶剂和凝胶基质,既促进冰片充分溶解,又维持了溶液整体的渗透压和pH值,使其更加接近生理状态下的眼内环境。冰片属于醇溶性晶体,难溶于水,对粘膜组织具有一定刺激性。本研究选择RH40-PEG400(8:2)混合溶液替代乙醇作为冰片的增溶剂,促进冰片充分溶解的同时,避免了乙醇对眼部组织刺激性和潜在损伤。同时选择离子型纤维素胶CMC-Na作为滴眼剂凝胶基质,该物质作为缓解干眼症的药物在临床已广泛应用,CMC-Na凝胶基质使用可以增加药物在眼球表面的停留时间,降低滴眼剂对角膜的刺激感,使患者用药的顺应性进一步提升。
(4)本发明的药物对视网膜变性损伤具有很好的保护作用,将冰片与CNTF组联用发挥协同优势,视网膜变性的主要病理特点是视网膜细胞凋亡,而炎症反应是导致细胞凋亡的重要机制之一。冰片在古医典中记载具有清热明目功效,现代药理研究发现冰片具有很好的抗炎作用,除此之外,冰片促进了CNTF在视网膜中的分布,而许多研究已证实CNTF对视网膜神经细胞具有保护作用。我们的研究发现,从组织形态学、功能学角度冰片CNTF滴眼剂均显示了很好的保护作用,用药后视网膜组织形态接近正常组,视网膜细胞凋亡明显减轻,视网膜电图检查也显示出对动物模型的视功能有明显改善。单纯冰片滴眼剂组及单纯CNTF滴眼剂组作用较弱。
