第二方面,本申请提供了一种复合制剂在治疗激素依赖性皮炎中的应用。
为了证实复合制剂具有上述新用途,本申请进行了如下实验。
1.复合制剂制备工艺优化及质量标准研究
1.1“地榆煎”浸膏制备
按照1.5:1.5:1:1:1:1比例,分别取龙胆草,生地榆,苦参,牡丹皮,紫草,甘草6味中药,粉碎。因牡丹皮主要活性成分丹皮酚易随水蒸气挥发,紫草主要活性成分紫草素不溶于水等特点,对传统水煎煮法进行改良。
取牡丹皮粉碎饮片,以10倍量纯化水浸泡4h,水蒸气蒸馏,回收乳白色蒸馏液,即含丹皮酚溶液,加入5%NaCl,4℃冰箱放置过夜。可见析出白色结晶,采用定性滤纸过滤,纯化冷水冲洗后,即得白色结晶样丹皮酚提取物,称重。
取紫草粉碎饮片,用5倍量80%乙醇浸泡12h,收集提取液,药渣再加10倍量80%的乙醇渗漉4h,将两次提取液合并,得紫草素提取液。
将上述经提取后的牡丹皮、紫草药渣与剩余4味药进行水煎煮法提取,药液与上述紫草素提取液合并,浓缩至干,即得“地榆煎”浸膏,称重。
1.2不同浓度梯度复合制剂制备
依据中药提取物(丹皮酚提取物及地榆煎浸膏)所占复合制剂百分比分别参照上法制备为不同浓度梯度复合制剂,即低剂量组(2.5%)、中剂量组(5%)、高剂量组(10%)。
各组凝胶配制:
低剂量组具体为凝胶低剂量组:卡波姆1.03%、甘油8.21%、氮酮0.51%、羟苯甲酯0.10%、三乙醇胺0.62%、纯化水87.03%、丹皮酚提取物0.01%、地榆煎浸膏2.49%。
中剂量组具体为凝胶中剂量组:卡波姆1.00%、甘油8.00%、氮酮0.50%、羟苯甲酯0.10%、三乙醇胺0.60%、纯化水84.80%、丹皮酚提取物0.01%、地榆煎浸膏4.99%。
高剂量组具体为凝胶高剂量组:卡波姆0.95%、甘油7.58%、氮酮0.47%、羟苯甲酯0.09%、三乙醇胺0.57%、纯化水80.34%、丹皮酚提取物0.02%、地榆煎浸膏9.98%。
1.3制剂基质成分筛选
1.3.1增稠剂
常用凝胶剂基质有卡波姆940、明胶、羟甲基纤维素钠、海藻酸钠、透明质酸等。分别取以上5种基质各0.5g,加入50ml纯化水中,考察各基质溶胀性、颜色、涂展性,筛选出最佳基质。
1.3.2PH调节剂
PH值可影响角质形成细胞的功能,从而影响角质层功能恢复。因此,制剂需符合皮肤表面PH值范围。因部分增稠剂如卡波姆呈酸性,需调节其PH值至正常范围,鉴于对皮肤刺激性、制剂安全性等诸多因素,本申请将三乙醇胺作为PH调节剂。
1.3.3保湿剂
本申请剂型为水性凝胶,长期放置可因失水而变干燥,影响涂抹,故需加入一定保湿剂。常用保湿剂为甘油和丙二醇等,甘油用量范围为5%~15%,丙二醇用量范围为5%~10%。
1.3.4透皮促渗剂
由于皮肤独特的皮肤屏障作用,大多数药物难以通过皮肤吸收,因此,需借助透皮促渗剂,以提高经皮吸收药物浓度。常用透皮促渗剂为氮酮,用量范围为1%~6%。
1.3.5抑菌剂
凝胶长期放置易霉变,常需加入抑菌剂,常用安全性高的抑菌剂为羟苯甲酯、羟苯乙酯,用量范围为单一酯类最大允许用量不超过0.4%(以酸计)。
1.4正交实验设计
凝胶剂处方中卡波姆-940用量多在1%。中药浸膏用量多在5%-15%,甘油用量范围为5%-15%,氮酮用量范围为0.5%-1.5%,抑菌剂用量低于0.4%。据此设计正交试验,以成型性、涂展度、粘度、气味、耐寒性、耐热性、离心稳定性作为凝胶制备工艺考察标准,得出如上复合制剂最佳配比处方。
1.5复合制剂制备
在纯化水中加入增稠剂卡波姆,加热30min,待其充分溶胀,按上述最佳配比依次加入保湿剂甘油、透皮促渗剂氮酮、抑菌剂羟苯甲酯、丹皮酚提取物、地榆煎浸膏,加入PH调节剂三乙醇胺调节PH值至6-7,搅拌均匀即得所述复合制剂。
2.技术方案
(1)建立HDD豚鼠模型:
豚鼠的表皮和真皮均在正常人体皮肤厚度范围之内,豚鼠的一般生理指标,以及血液学和血液化学成分等方面也与人相近,故本申请选用豚鼠进行研究。
购买雌性豚鼠53只,实验前适应性饲养7d后开始实验,自由进食。53只豚鼠于背部左右两侧对称部位选5cm×5cm区域剃毛,脱毛膏脱去残余毛发,随机抽取45只用于HDD模型建立。
其中,采用的建模方法如下:造模药物选用0.05%丙酸氯倍他索酊剂。用含0.05%丙酸氯倍他索酊剂均匀涂于背部右侧,另一侧用75%酒精涂抹作为自身对照,涂抹剂量为使液体均匀覆盖裸露皮肤即可。剩余8只即为空白对照组,均在背部右侧涂抹75%酒精,另一侧不做任何处理,该8只豚鼠做空白对照组(涂抹酒精做空白对照目的是为了说明酒精对造模过程无影响)。模型组每天涂药2次,并按摩1-2min,直至充分吸收,连续7周,停药2-3天后,随机选取5只取材,观察皮肤组织形态学变化以验证模型是否成功建立。
(2)技术路线
图1为本申请提供的技术路线示意图,参见图1,剩余40只HDD模型豚鼠造模成功7d后,随机分5组,每组8只,分别为空白基质组(空白基质凝胶)、阳性对照组(0.03%他克莫司软膏)、地榆凝胶低剂量组(2.5%)、中剂量组(5%)、高剂量组(10%)。各制剂涂抹剂量为使药物均匀覆盖裸露皮肤即可,每日涂药2次,连续涂药3周。自给药开始每天观察实验动物背部激发部位皮肤的改变,如红斑、丘疹及肿胀的情况。于末次给药12h后,脱毛,予麻醉后,取材。
(3)技术方法
单因素分析、正交试验法确定地榆凝胶的辅料最优处方和制备工艺;高效液相、薄层色谱分析法对地榆凝胶进行定量、定性检测;采用《中药色谱指纹图谱相似度评价系统2012版》对不同批次地榆凝胶共有峰进行相似度及主成分分析。采用HE染色、免疫组化法对皮肤组织进行形态学观察;WB等免疫学实验技术方法检测相关蛋白表达情况。通过对HDD豚鼠模型治疗前后的相关指标进行检测,探讨地榆凝胶的治疗机制和作用;运用皮肤镜、皮脂测试仪等设备对HDD豚鼠模型进行客观评价。
进一步地,具体进行的指标检测如下:
(1)皮肤含水量、油脂及皮肤镜检测
分别于HDD模型建立前、后及治疗后,使用皮脂测试仪检测皮肤含水量、油脂情况;皮肤镜检测表皮、真皮结构变化。
(2)局部皮肤病理形态学观察
取豚鼠背部皮肤,0.5×0.5cm,去掉皮下脂肪后,4%多聚甲醛液固定。HE染色后观察皮肤形态学变化。
3.实验结果
3.1豚鼠HDD皮肤变化
本申请于豚鼠背部两侧进行脱毛处理,脱毛区范围约5*5cm,左侧涂抹75%酒精,右侧涂抹丙酸氯倍他索酊剂。涂抹49天后,参见图2中的视图b和视图c,豚鼠右侧皮肤出现红肿、皮屑等症状,视图d模型组涂抹空白基质凝胶治疗,视图e阳性对照组予他克莫司软膏治疗,视图f、g、h分别给予地榆凝胶低、中、高剂量组治疗。3周后,可见经空白基质凝胶治疗后,红肿仍未消退;地榆凝胶低剂量组皮肤仍可见部分潮红,经他克莫司软膏、地榆凝胶中、高剂量组治疗后,皮肤红肿消退明显,皮屑消退,表明地榆凝胶对HDD具有缓解作用。
3.2地榆凝胶对豚鼠HDD干预前后皮肤含水量检测
本申请于治疗前、后采用皮脂检测仪对HDD模型豚鼠进行检测,结果如表1所示。采用SPSS 23.0进行实验数据分析,模型组水份、油份含量较空白组水份、油份含量降低,差异有统计学意义(P<0.05),可以看出长期糖皮质激素的应用可使皮肤水分及油份减少,HDD模型制造成功。地榆凝胶低、中、高剂量组及阳性对照组水份、油份含量较模型组水份、油份含量升高,差异有统计学意义(P<0.05),表明本制剂可提高皮肤水份、油份含量,对HDD具有缓解作用。
表1地榆凝胶对豚鼠HDD皮肤水份、油份含量影响(x±s,n=8)
3.3地榆凝胶对豚鼠HDD干预前后红外成像测试仪检测
本申请于治疗前、后采用红外成像测试仪对HDD模型豚鼠进行检测,结果如表2所示。采用SPSS 23.0进行实验数据分析,模型组造模区体温较空白组造模区体温升高,差异有统计学意义(P<0.05),表明长期糖皮质激素的应用可使皮温升高,HDD模型制造成功。地榆凝胶高剂量组及阳性对照组造模区体温较模型组升高,差异有统计学意义(P<0.05),表明本制剂可降低HDD造模区皮温,对HDD具有缓解作用。
表2对豚鼠HDD干预前后红外成像测试仪检测造模区皮温(x±s,n=8)
3.4地榆凝胶对豚鼠HDD干预前后皮肤镜观察
图3可见,皮肤镜显示模型组豚鼠表皮下毛细血管扩张,表皮上可见散在鳞屑分布,表明HDD模型造模成功。地榆凝胶低剂量组治疗后,鳞屑明显减少,仍可见毛细血管扩张。地榆凝胶低、中、高剂量组及他克莫司凝胶治疗后,可见鳞屑明显消退,地榆凝胶中、高剂量组毛细血管扩张充血状态均较模型组改善明显,表明地榆凝胶对HDD具有缓解作用。
3.5地榆凝胶对豚鼠HDD干预后组织病理改变
图4为本申请提供的皮肤组织HE染色病理结果示意图。参见图4,模型组角质层融合性角化不全,表皮层可见明显增生,棘层肥厚,表皮层不规则向下延伸,真皮层毛细血管扩张充血,真皮乳头及真皮毛细血管周围淋巴细胞浸润,表明HDD模型造模成功。相比于模型组,地榆凝胶中、高剂量组及阳性对照组皮肤较模型组皮肤角质层结构及棘层增生改善,皮肤变薄;地榆凝胶高剂量组较地榆凝胶中剂量组及阳性对照组炎症部位减少,表明地榆凝胶对HDD有缓解作用。
由以上技术方案可知,本申请旨在研究地榆凝胶对HDD豚鼠模型干预效果,因此,模型成功建立后,本申请通过皮肤镜、皮脂测试仪等设备,从局部皮损微观状态、皮肤水份、油脂含量等对皮炎模型进行客观评价,以期为激素依赖性皮炎提供客观的量化评价标准。进一步本申请设地榆凝胶不同浓度并分组,分为低剂量组(浸膏2.5%)、中剂量组(浸膏5%)、高剂量组(浸膏10%),通过比较不同浓度复合制剂在改善皮肤炎症、修复皮肤屏障等方面的效果,筛选最佳药物浓度。
