Abstract
涉及一种洛索洛芬钠或含有洛索洛芬钠的组合物在制备预防和/或治疗干眼的药物中的应用。
Description
本申请要求申请日为2021年07月09日的中国专利申请202110780762.8的优先权，其全部内容通过引用结合在本申请中。
本发明涉及医药领域，具体涉及洛索洛芬钠或含有洛索洛芬钠的组合物在制备预防和/或治疗干眼的药物中的应用。
干眼，又称为角结膜干燥综合征。国际泪膜和眼表协会TFOS(the Tear Film&Ocular Surface Society)在2015年举行的第二次工作组干眼病会议将干眼重新定义，即：干眼(dry eye disease，DED)是眼表的一种多因子疾病，特征是泪膜稳态的丧失并伴有眼表症状，主要为眼部干涩感、异物感、灼热感、经常会伴随眼部有粘稠分泌物，由于睡眠质量差，用眼过度加重，严重者甚至会影响视力和正常生活。
近些年来，干眼的发病率呈逐年上升的趋势，已经成为最普遍的眼科疾病之一。从世界范围来看，干眼发病率处在5.5％～33.7％，从发病率来看，女性高于男性，老年人高于青年人，亚洲人高于以及其他地区的人。国外的流行病学报道显示，在30～40岁人群中，干眼的患病率为20％；而70岁以上人群中，干眼的得病率高达36.1％，这些人群中女性的患病率依旧高于男性。
干眼的病因有很多，包括自身因素，如泪膜受损、泪腺功能障碍、睑板腺功能障碍、眼表蛋白表达异常、维生素A缺乏、性激素失调、神经调节异常等。许多系统性疾病也会引起干眼，如系统性红斑狼疮、糖尿病、干燥综合征、类风湿性关节炎、睡眠障碍、围绝经期综合征、甲状腺病、过敏性结膜炎等，干眼的发生还与年龄相关。另外，干眼的发生还包括很多环境因素，如环境污染或环境过度干燥，眼部手术及过度使用眼部药物，视频终端过度使用以及角膜接触镜的佩戴等因素都会导致干眼病的发生。经常从事户外工作的工作者会更容易出现干眼。虽然对干眼的发病因素进行了很多研究，但是干眼的发病机制并未完全明确。
洛索洛芬钠是一种非甾体抗炎药，临床上被用于类风湿性关节炎、腰痛、肩周炎、 颈肩腕综合症等的抗炎镇痛、手术、外伤后及拔牙后的镇痛消炎和急性上呼吸道炎症的解热镇痛等，目前还没有关于洛索洛芬钠治疗干眼的报道。

为了便于实验，本发明制备了含有洛索洛芬钠的水溶液组合物，组成如下表1所示(表1中的洛索洛芬钠的质量以C
15H
17NaO
3计)。
表1：组合物组成

实施例1：对碱烧伤致新西兰兔干眼的影响
1、造模方法
每只新西兰兔采用1％的丙泊酚注射液静脉注射麻醉(1.5ml/kg)，待动物维持麻醉稳定后用2％的盐酸利多卡因注射液100μl滴眼表面麻醉。动物维持在麻醉第三期时，用1张约10mm×5mm大小的滤纸条蘸1mol/L的NaOH溶液后置于距兔角膜缘上方约2mm的睑结膜上，90s后立即用约50ml 0.9％氯化钠注射液反复冲洗结膜囊。
2、结膜荧光素染色
使用移液器在新西兰兔右眼结膜囊内滴入2μl的0.5％荧光素钠溶液，5s后用 0.9％氯化钠注射液冲洗多余的荧光素，在裂隙灯显微镜下，钴蓝色弥散光观察结膜染色情况。结膜荧光染色评分标准：将结膜分成四个象限，每个象限根据染色程度和面积分为四个等级：0分为无染色；1分为散在点状染色；2分为密集点状染色；3分为片状染色，共12分(左眼未造模，作为阴性对照眼)。
3、结膜虎红染色
使用移液器在新西兰兔右眼结膜囊内滴入2μl的1％虎红，5s后用0.9％氯化钠注射液冲洗多余的虎红，在裂隙灯显微镜下，绿光观察结膜染色情况。结膜虎红染色评分标准与结膜荧光染色标准一致。
4、泪液分泌量(双眼)
采用Schirmer I实验(Schirmer I test)测量新西兰兔泪液的分泌。即用眼科镊夹住酚红棉线，置于新西兰兔外眦部，60秒后取出测量酚红棉线湿润的长度。
5、泪膜破裂时间(双眼)
使用可调移液器在新西兰兔眼下睑结膜囊内滴入2μl的0.5％荧光素钠溶液，以恒定力手动眨眼数次后，以恒定力撑开兔眼，用裂隙灯显微镜，钴蓝光观察角膜，当角膜绿色薄膜出现黑区时，表示泪膜破裂。连续测3次，取其平均值，结果如表2所示。
表2：对碱烧伤兔泪膜破裂时间的影响
注：与阴性对照眼比，#表示P<0.05，##表示P<0.01；与模型对照组相比，*表示P<0.05，**表示P<0.01(阴性对照眼为左眼，模型对照组为给予等容积的0.9％氯化钠注射液)。
表2数据可以看出，组合物1在给药后第一天(D1)对泪膜破裂时间未见明显差异(P>0.05)。但在给药后第五天(D5)、第九天(D9)对泪膜破裂时间均明显延长，有统计学差异(P<0.05或0.01)。
表3：对碱烧伤兔眼科评分的影响
注：与模型对照组比，#表示P<0.05，##表示P<0.01(模型对照组为给予等容积的0.9％氯化钠注射液)。
表4：对碱烧伤兔眼科评分的影响
注：与模型对照组比，#表示P<0.05，##表示P<0.01(模型对照组为给予等容积的0.9％氯化钠注射液)。
组合物对碱烧伤兔眼科荧光素钠评分和虎红染色评分的影响分别如图1和图2所示。结合图1、图2以及表3和表4的数据可以看出，与模型对照组相比，含有洛索洛芬钠的组合物1在给药后第五、九天对眼科评分具有明显降低作用。可见，含有洛索洛芬钠的组合物可以有效地缓解眼损伤。
表5：对碱灼伤兔酚红棉线湿润长度的影响
注：与阴性对照眼比，#表示P<0.05，##表示P<0.01。(阴性对照眼为左眼)
从以上表2～表5的数据可知，含有洛索洛芬钠的组合物对碱烧伤致兔干眼模型具有明显的改善作用，其改善作用主要表现为增强泪膜稳定性、增加泪液分泌量以及缓解角膜上皮细胞损伤(主要表现为降低眼损伤局部水肿)。此外，通过病理研究报告研究得知，含有洛索洛芬钠的组合物还具有增加杯状细胞的效果。
本实施例采用同样的方法对组合物2～4进行了检测，组合物2～4对于碱烧伤致兔 干眼模型均具有明显的改善作用，且与组合物1的效果没有明显差异。
实施例2：对小鼠结膜干燥综合症的影响
1、抗原制备方法
取同种小鼠，用颈椎脱臼法安乐死，常规方法眼周消毒，在超净工作台上整取出结膜，用含8万/500mL庆大霉素的生理盐水洗净，放于含8万/500mL庆大霉素的生理盐水中，将结膜剪成碎片，在匀浆器中碾成匀浆。保持4℃，在超声破碎机上破碎1h再放于离心机离心(3000r/min，×15min)。取出上清液，考马斯亮蓝法测定蛋白含量。然后再用0.14MPBS将蛋白浓度稀释至100μg/mL。在完全弗氏佐剂(FCA)中加入等体积的结膜抗原溶液，充分混匀成油包水溶液。
2、实验方法
将上述油包水溶液多点注射于鼠背部皮下、四肢腋下淋巴结和足垫，总量为0.5mL。具体而言：
(1)泪膜破裂时间(BUT)：使用微量加液器在BALB/c小鼠下方结膜囊内滴入1μl用裂隙灯显微镜的钴蓝光观察角膜，当角膜绿色薄膜出现黑区时，表示泪膜破裂。连续测3次，取其平均值。正常BUT为10～15秒，少于10秒为异常，重复测量3次，取平均值。
(2)BALB/c小鼠的泪液分泌实验：采用Schirmer I实验(Schirmer I test)测量BALB/c小鼠泪液的分泌量。即用眼科镊夹住酚红棉线，置于BALB/c小鼠外眦部，60秒后取出测量酚红棉线湿润的长度。
(3)统计分析方法：所有数据均输入EXCEL进行统计分析，各组计量数据均计算
各实验组进行组间比较之前先进行组间方差分析(F-test)，当组间方差齐同时，组间比较采用Student-T检验(非配对的T检验)进行统计，组间方差不齐时，采用校正的Student-T检验进行统计分析。
表6：对小鼠结膜干燥综合征模型泪膜破裂时间的影响
注：与空白对照组比，#表示P<0.05，##表示P<0.01；与模型对照组比，#表示P<0.05，##表示P<0.01。
表7：对小鼠结膜干燥综合征模型酚红棉线湿润长度的影响
注：与空白对照组比，#表示P<0.05，##表示P<0.01；与模型对照组比，#表示P<0.05，##表示P<0.01。
根据表6、表7的实验数据可知，组合物1对小鼠结膜干燥综合症模型具有明显的改善作用，其改善作用主要表现为增加小鼠泪液的分泌量以及延长泪膜破裂时间。
本实施例采用同样的方法对组合物2～4进行了检测，组合物2～4对于小鼠结膜干燥综合症模型均具有明显的改善作用，且与组合物1的效果没有明显差异。
实施例3：刺激性实验
1、滴眼液来源：
普拉洛芬滴眼液：市售，厂家为Senju Pharmaceutical Co.，Ltd.Fukusaki Plant；
双氯芬酸钠滴眼液：市售，厂家为郑州卓峰制药有限公司；
洛索洛芬钠滴眼液：组合物1经0.22μm微孔滤膜过滤后所得。
2、实验操作：每组各选择20名干眼患者，随机双盲使用三种滴眼液，来对比浓度均为0.1％的普拉洛芬、双氯芬酸钠、洛索洛芬钠滴眼液对于患者眼部的刺激性症状。眼部刺激症状包括有如烧灼感、刺痛感或者流泪等症状。统计结果如表8所示。
表8：刺激性对比实验记录
根据初步统计的结果，有40％的双氯芬酸钠滴眼液组出现了至少1种眼部刺激症状；20％的普拉洛芬滴眼液组出现了至少1种眼部刺激症状；而洛索洛芬钠滴眼液使用组，仅有一例患者出现眼部刺激症状，而且是刺激性比较小的流泪症状，其他患者普遍反映使用之后，眼部舒适感强，因此可以长期使用，同时也比较适合应用于儿童干眼患者。
本实施例采用同样的方法对组合物2～4进行了检测，发现组合物2～4提供滴眼液刺激性都比较小。
虽然，上文中已经用一般性说明、具体实施方式及试验，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。
