Description
技术领域
本发明涉及生物医药技术领域,具体涉及一种治疗阴道炎的组合物及应用。
背景技术
女性生殖系统由于其结构的特殊性,极易发生妇科炎症,包括阴道炎、宫颈炎、子宫内膜炎、盆腔炎等。按照感染的病原微生物分为细菌性阴道炎、病毒性阴道炎、真菌性阴道炎、滴虫性阴道炎等。据世界卫生组织公布的统计数据,女性一生中妇科炎症的发病率约为90%;妇科炎症一般在20岁到45岁之间为高发年龄段,且不同年龄段都有代表性的病症,老年女性易罹患老年性阴道炎。妇科炎症的病因复杂,分为生理性原因和病理性原因,包括经期不注意卫生;宫腔手术操作消毒不严;人流、分娩等妇科手术对宫颈及阴道造成损伤,引发感染;性生活对妇科局部组织产生损伤或交叉感染等。
治疗妇科炎症的主要治疗方法是使用侵入性手术、康复理疗法、激素疗法以及固体乳膏或喷雾剂等药物治疗,这些方法虽然能在一定程度上缓解症状,但缓解通常是暂时的,许多患者在治疗后仍会复发,手术过程中存在相当大风险,易形成阴道瘢痕、神经损伤和感觉功能下降,且药物长期使用会导致耐药性,菌群失调。药物治疗中,长期使用药物、激素等会导致病灶部位耐药和药物带来的副作用;女性生殖系统防御力受损是发生妇科疾病的主要成因,其中阴道及宫颈粘膜受损是防御力下降的主要原因,但目前市面上没有一种药物或产品可以促进阴道及宫颈粘膜再生,这对于保护女性生殖系统健康是一个重要的瓶颈。
富含细胞因子的UCMSC治疗在阴道炎疾病中有其独特的优势。相比其他药物,细胞因子治疗可以直接作用于受损组织,促进组织修复和再生。其作用机制是细胞因子能够刺激细胞增殖、分化和迁移,促进组织修复和愈合过程。它们可以启动细胞内信号传导通路,促使损伤部位的细胞进行增殖并分化为功能性细胞,从而加速组织的恢复。细胞因子还可以调节炎症反应,在阴道粘膜损伤时起到抗炎作用。它们能够调节炎症细胞的活化和迁移,并抑制炎症介质的释放,从而减轻炎症反应,促进伤口愈合。某些细胞因子可以刺激血管内皮细胞的增殖和血管生成,促进新血管的形成,提高组织的血液供应。这些有助于改善组织的氧供和营养供应,促进伤口愈合。
发明内容
为此,本发明提供一种治疗阴道炎的组合物及应用,以解决上述的问题。
为了实现上述目的,本发明提供如下技术方案:
根据本发明第一方面提供的一种治疗阴道炎的组合物,所述组合物包括基液和添加因子;其中,添加因子包括MS培养基、维生素E、布洛芬、调节蛋白β1、成纤维生长因子、表皮生长因子EGF和脐带间充质干细胞UCMSCs。
进一步的,所述添加因子包括MS培养基10-100mg/mL、维生素E 100-200μg/ml、布洛芬5-10mg/ml、调节蛋白β1 20-50ng/ml、成纤维生长因子FGE 1-10ng/ml、表皮生长因子EGF 1-10ng/ml和脐带间充质干细胞UCMSCs 1×107/ml。

UCMSCs,即脐带间充质干细胞,具有多向分化潜能和组织修复能力,可以分化为多种细胞类型,如成纤维细胞、血管内皮细胞、平滑肌细胞等,从而促进受损组织的修复和再生;还可以分泌多种细胞因子和生长因子,如炎症因子、转化生长因子-β(TGF-β)、表皮生长因子(EGF)等,这些因子可以抑制炎症反应、减轻组织损伤,并促进组织修复;还可以分泌血管生成因子(VEGF)等,促进新血管生成,改善局部血液循环,提高氧气和营养物质的供应,从而促进组织修复和再生。UCMSCs还可以调节免疫功能,抑制免疫反应,减轻炎症反应,降低组织损伤程度,促进组织修复。
MS培养基(货号:HZ1012-1)含蔗糖和琼脂以及大量元素(氮、磷、钾、镁、钙)、微量元素(碘、硼、硫、锌、钴、铜、钼)、铁盐(硫酸亚铁)和有机成分(肌醇、烟酸、盐酸吡哆醇、硫胺素、甘氨酸、蔗糖)维持细胞的生长和增殖。延长细胞在病灶部位的存活时间。
维生素E(货号:S66679-25):具有抗氧化作用,可以保护细胞膜免受氧化损伤,病灶部位是一个低氧环境,维生素E可以降低细胞移植后氧化应激带来的死亡。
布洛芬(CAS号:15687-27-1):是一种非甾体抗炎药,可以减轻炎症、疼痛和发热。
调节蛋白β1(Heregulinβ1),(货号:xy100-03):是一种细胞因子,参与多种细胞信号传导途径,在细胞增殖和分化中发挥作用。
成纤维生长因子FGF(CAS:62031-54-3):促进细胞增殖、分化和修复,有助于组织再生。
表皮生长因子EGF(CAS:62229-50-9):促进表皮细胞增殖和修复,有助于皮肤组织的再生。
进一步的,所述基液为0.9%的 NaCl溶液和甘油组成。
根据本发明第二方面提供的如上所述的组合物在制备治疗阴道炎制剂中的应用。
进一步的,所述制剂为注射液。
根据本发明第三方面提供的一种治疗阴道炎的注射液,所述注射液的制备方法包括:将MS培养基、维生素E、布洛芬、调节蛋白β1、成纤维生长因子FGE和表皮生长因子EGF溶解在0.9%的 NaCl溶液中,完全溶解后,加入UCMSCs,混合均匀后加入甘油混合后即得治疗阴道炎的注射液。
进一步的,0.9%的 NaCl溶液与甘油体积质量比为9.5mL:0.5ml。
本发明具有如下优点:
本发明的组合物改变了现有治疗方式,本发明通过使用细胞治疗,可以促进阴道组织修复和再生,从根本上解决问题,长期效果会更好,能够从源头减少复发率。
本发明的注射液通过改变阴道内的微生态平衡,促进有益菌群生长,提高治疗效果。

实验例
一、制作大鼠阴道炎模型需要以下步骤:
1. 准备工具和材料:手术刀、镊子、注射器、无菌生理盐水、2%利多卡因麻醉液、阴道加德纳菌和白色链球菌混合剂、消毒液、无菌手套、无菌口罩、无菌手术衣等。
2. 选取雌性大鼠,体重在200-250g之间。
3. 用消毒液清洗外阴部,用镊子将阴唇分开,准备阴道加德纳菌和白色链球菌混合剂,用灭菌0.1ml 注射器抽取含加德纳菌和白色链球菌混合剂0.25×106个/ml的菌液,造模SD大鼠取头朝下位,将 0.1ml 混合菌液注入阴道内,原位停留1~2min,防止菌液溢出。24h 后同样方法再感染1次。感染后造模动物隔日交替皮下注射氢化可的松各2 次,以保持假动情期和全身免疫功能低下状态,增加混合剂在阴道内的易感性。
4.造模成功的鉴定:用镊子扩开大鼠阴道口,感染后 4 天可见造模SD大鼠外阴红肿,伴少量白色分泌物,用无菌棉签蘸取分泌物,涂于沙氏培养基表面,25℃培养48h,肉眼观察可见大小不等的白色菌落,分泌物镜检可见假菌丝和成群狍子,正常大鼠局部组织呈现柔软、湿润、光滑的状态,而模型鼠出现了红肿、渗出等炎症症状。
二、动物给药
将造模完成后,将108只造模大鼠随机分9组,每组12只,分别为实验组1、实验组2、实验组3,对比组1、对比组2、对比组3、阳性对照1(简称阳性1)、阳性对照2(简称阳性2)和模型组。实验组1使用实施例4的方案进行治疗,实验组2使用实施例5的方案进行治疗,实验组3使用实施例6的方案进行治疗;对比组1使用对比例1的方案进行治疗;对比组2使用对比例2的方案进行治疗;对比组3使用对比例3的方案进行治疗;空白对照组给予同样药量的生理盐水。给药方法:使用无菌给药器进行给药。24h后再次重复以上操作。
健康空白对照组(简称空白组,健康未造模的小鼠9只);
阳性药物:阳性1组:复方甲硝唑阴道栓(规格:3 g/粒,厂家:河北万通金牛药业有限公司,国药准字H13024554),阳性2组:洁尔阴洗液(四川恩威制药有限公司,批号:1107102)。
菌落计数方法:用0.1ml无菌生理盐水冲洗阴道,对冲洗液内的加德纳菌和白色链球菌进行菌落培养;
1. 统计分析给药14d后小鼠阴道内菌落数的生长情况,观察药物对感染大鼠阴道加德纳菌和白色链球菌的杀灭或抑制作用。在给药第14d后收集大鼠阴道分泌物的灌洗液,观察其在血琼脂培养皿中的生长情况,并每天观察小鼠阴道充血、红肿和分泌物等的变化情况。分别统计给药14d和给药20d的治愈时间和治愈率。以连续3d阴道内容物在沙氏琼脂平板上未见加德纳菌和白色链球菌生长,且阴道无分泌物,无明显充血、肿胀等临床症状判定为治愈,治愈小鼠不再用药。
表1本发明注射液对阴道炎的治愈情况分析
注:在用药14d统计结果中,14d内未治愈小鼠的治愈时间记为15d。
在用药20d统计结果中,20d内未治愈小鼠的治愈时间记为21d。
用药14d时,本发明实验组在14d内对阴道炎模型小鼠的平均治愈时间分别为6d、9d和9.5d,治愈率分别为83.3%、75%和41.7%;与模型组(平均自愈时间为0d,自愈率为0%)比较,本发明实验组治愈时间显著减少(P<0.05),本发明实验组组治愈率显著提高;与阳性药物复方甲硝唑阴道栓相比,无显著性差异。
用药20d时,本发明实验组在20d内对阴道炎模型小鼠的平均治愈时间分别为15.5d、17d和19.2d,治愈率均为91.7%、83.3%、75%;与模型组(平均自愈时间为0d,自愈率为0%)比较,本发明实验组治愈时间均极显著性减少(P<0.01),本发明实验组治愈率显著提高;与阳性药物复方甲硝唑阴道栓相比,无显著性差异。
实验结果说明本发明注射液具有治疗加德纳菌和白色链球菌性阴道炎的作用。
2. 炎症因子的变化
IL-1β是一种重要的炎症因子,能够诱导炎症反应。在阴道炎疾病中,当阴道受到感染或刺激时,免疫细胞(如单核细胞、巨噬细胞)会释放IL-1β。IL-1β通过与其受体结合,激活下游信号通路,引发炎症细胞的浸润和活化,导致局部组织炎症反应。IL-1β参与调节炎症过程中的免疫细胞活化和功能。IL-1β可以促进T细胞的活化和增殖,增强巨噬细胞的吞噬作用,调节炎症介质的释放,从而影响免疫应答的程度和方向。影响细胞增殖和分化:IL-1β也能够促进细胞增殖和分化。在阴道炎疾病中,IL-1β可能通过影响上皮细胞的增殖和分化,参与阴道黏膜的修复和再生过程。当给药14d时,收集每只大鼠的阴道灌洗液样品,检测后,如图1所示可知,未经治疗的模型组的IL-1β的表达显著高于空白组及其他实验组、对照组及阳性组。与实验组1对比发现,实验组2-3,对照组1-3的IL-1β表达量明显下降,差异具有统计学意义(P<0.05)。与实验组1相比,阳性组1-2的IL-1β有下降趋势,但差异不明显,无统计学意义(P>0.05)。
INF-γ(干扰素-γ)是一种重要的免疫调节因子,能够促进巨噬细胞、T淋巴细胞和自然杀伤细胞等免疫细胞的活化。INF-γ可以促进炎症介质的释放,如促炎细胞因子和趋化因子,引导炎症细胞的浸润和活化,加剧炎症反应,在阴道炎疾病中,INF-γ通过调节免疫细胞活化、促进炎症反应、调节细胞凋亡和影响细胞增殖等途径影响疾病的进程。当给药14d时,收集每只大鼠的阴道灌洗液样品,检测后如图2所示,未经治疗的模型组的INF-γ的表达显著高于空白组及其他实验组、对照组及阳性组。与实验组1对比发现,实验组2-3,对照组1-3,阳性组1的INF-γ表达量明显下降,差异具有统计学意义(P<0.05)。与实验组1相比,阳性组2的INF-γ有下降趋势,但差异不明显,无统计学意义(P>0.05)。
IL-6(白细胞介素-6)是一种重要的炎症因子,它在免疫反应和炎症过程中发挥关键作用。IL-6主要由T细胞、B细胞、单核细胞、巨噬细胞和内皮细胞等多种细胞产生。IL-6通过结合其受体IL-6R,激活信号传导通路,包括JAK-STAT信号通路,促进炎症反应和免疫细胞的活化。在阴道炎疾病中,IL-6能够诱导炎症反应,增加炎症细胞的浸润和活化,导致局部组织炎症。IL-6参与调节Th细胞分化和活化,影响免疫细胞的功能,对细胞介导的免疫应答起调节作用。当给药14d时,收集每只大鼠的阴道灌洗液样品,检测后如图3所示,未经治疗的模型组的IL-6 的表达显著高于空白组及其他实验组、对照组及阳性组。与实验组1对比发现,实验组2,对照组1-3,阳性组1-2的IL-6表达量明显下降,差异具有统计学意义(P<0.05)。与实验组1相比,实验组3的IL-6 有下降趋势,但差异不明显,无统计学意义(P>0.05)。
TNF-α由Th1细胞分泌,是介导细胞免疫的关键因素,主要来源于单核细胞和巨噬细胞。在女性阴道炎症中,TNF-α扮演重要角色。正常情况下,宫颈和阴道上皮细胞中仅少量存在TNF-α,不被广泛分泌。但当受到外部细菌刺激时,TNF-α会迅速释放。TNF-α是人体炎症和免疫反应的关键调节因素,可诱导局部炎症反应、细胞粘附、炎症细胞聚集,并诱导内源性炎症因子如IL-1β、IL-6和IL-8。因此,TNF-α的表达水平在一定程度上反映了身体对特定抗原刺激的免疫状态。当给药14d时,收集每只大鼠的阴道灌洗液样品,检测后如图4所示,未经治疗的模型组的TNF-α 的表达显著高于空白组及其他实验组、对照组及阳性组。与实验组1对比发现,实验组2-3,对照组2-3,阳性组1的TNF-α表达量明显下降,差异具有统计学意义(P<0.05)。与实验组1相比,对照组1、阳性组2 TNF-α 有下降趋势,但差异不明显,无统计学意义(P>0.05)。
3.外阴阴道念珠菌病大鼠阴道菌落变化
根据前期数据,本发明淘汰了对比例1-3,给药前,与模型组比较,实验组、阳性对照组阴道内菌落数明显下降,具有明显统计学意义(P<0.01),给药后7d,实验组、阳性对照组与空白组各组之间的菌落数比较,均有统计学意义(P<0.05)。
给药后,与模型组相比,本发明以及阳性对照组阴道内菌落数明显下降;与阳性2组洁尔阴相比,本发明实验组以及阳性1组阴道内菌落数明显下降;与阳性1组药复方甲硝唑阴道栓相比,本发明实验组具有相似的体内抗加德纳菌和白色链球菌活性,随着给药时间的延长,菌落数呈明显下降趋势,病情逐渐好转,实验组1的效果优于复方甲硝唑阴道栓,实验组1-3疗效均优于洁尔阴。
治疗后菌落培养如图5所示,实验结果说明本发明的注射液能显著杀灭加德纳菌和白色链球菌。
虽然,上文中已经用一般性说明及具体实施例对本发明作了详尽的描述,但在本发明基础上,可以对之作一些修改或改进,这对本领域技术人员而言是显而易见的。因此,在不偏离本发明精神的基础上所做的这些修改或改进,均属于本发明要求保护的范围。
