Description
技术领域
本发明涉及中药组合物技术领域,尤其是涉及一种降血脂中药组合物及其制备方法和应用。
背景技术
血脂异常是指成人血浆总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白-胆固醇(LDL-C)升高和高密度脂蛋白(HDL)降低为特征的疾病。临床诊断符合TG≥1.7mmol/L、TC≥5.20mmol/L、高密度脂蛋白胆固醇(HDL-C)<1.04mmol/L、低密度脂蛋白胆固醇(LDL-C)≥3.38mmol/L中的任意一项,即可诊断为血脂异常。血脂升高可引发外周血管疾病、动脉粥样硬化、冠心病、胰腺炎等。
目前大量研究结果已充分表明,(TC)或LDL-C水平升高在动脉粥样硬化的发生和发展过程中起很重要的作用,与人群中冠心病的发病率和病死率呈显著的正相关。他汀类药物是目前降脂类药物的一线治疗方案,通过竞争性抑制HMG-CoA还原酶,从源头减少胆固醇的合成,可显著降低心血管事件的发病率和病死率。临床实践中他汀类药物最常报道的不良事件是相关的肌肉症状(SAMS),近年关于抑郁症、睡眠障碍等精神方面等不良影响的病例报告也越来越多。据记载中药降脂已有千年历史,天然药物成分能够有效改善血脂异常,随着近年来人们的关注,越来越多具有降脂功效的中药单体被人们发现。与西药降脂相比,中药降脂有其明显优势,具有更强的有效性以及更低的不良反应。

试验例一、中药组合物对大鼠高脂血症模型的影响
供试品和对照品:实施例1-6及对比例1-2制备的中药组合物(1g中药组合物相当于1.7g生药)、血脂康胶囊(北京北大维信生物科技有限公司,批号:20191209,规格:0.3g×36粒)。
实验试剂:胆固醇(广州晶欣生物科技有限公司)、去氧胆酸钠(广东环凯微生物科技有限公司)、丙硫氧嘧啶片(上海朝晖药业有限公司)、吐温-80(广东广试试剂科技有限公司)、1,2-丙二醇(广东广试试剂科技有限公司)、戊巴比妥钠(广州瑞舒生物有限公司)、大鼠同型半胱氨酸试剂盒(江苏酶免实业有限公司)、大鼠白介素6试剂盒(江苏酶免实业有限公司)、大鼠丙二醛试剂盒(南京建成生物工程研究所)、大鼠一氧化氮试剂盒(南京建成生物工程研究所)、大鼠超氧化物歧化酶试剂盒(江苏酶免实业有限公司)、大鼠脂蛋白(a)试剂盒(江苏酶免实业有限公司)、大鼠低密度脂蛋白试剂盒(南京建成生物工程研究所)和大鼠高密度脂蛋白试剂盒(南京建成生物工程研究所)。实验用溶媒为纯净水。
实验动物:SD大鼠,SPF级,180-220g,雄性,由广东省医学实验动物中心提供,实验动物生产许可证号:SYXK(粤)2018-0041,实验动物质量合格证明号:NO.44007200077683,用于中药组合物对高脂血症模型的影响试验。
实验动物的适应性观察:自接收之日起,所有动物进行适应性饲养观察,每天观察一次;观察内容包括:精神状态是否良好、行为活动是否正常、被毛是否光滑、有无便溏、眼睛有无异常、会阴部有无异常分泌物及溃烂、有无死亡。适应性饲养合格动物纳入正式实验。
环境条件:试验期间,动物实验室温度20℃-26℃,相对湿度40%-70%(WS-1型湿度记录仪记录),照明为12h/12h昼夜明暗交替。
分组:中药组合物临床拟用剂量为每日126g中药组合物,1g中药组合物=1.7g生药,按照成人60公斤体重计算,大鼠体重折算系数是6.25,则中药组合物拟用剂量为每日22.31g生药/kg,供试品实施例1的中药组合物设低、中、高3个剂量,分别等效于临床拟用剂量的0.5、1、2倍。阳性对照组药血脂康胶囊(以有效成分计算)临床拟用剂量为每日1.2g,大鼠等效剂量为0.126g·kg-1·d-1。阳性对照药使用剂量等效于临床剂量的1倍,分组及给药剂量见表1。
表1大鼠实验分组及剂量设计
统计分析:所有数据均用“均值±标准差”表示,试验数据运用SPSS17.0统计分析软件进行统计分析,定量资料组间比较采用单因素方差分析(One-Way ANOVA),以LSD检验进行各组间两两比较。P〈0.05为差异有统计学意义。
实验方法:SD大鼠,雄性,体重180-220g,适应性喂养7天后,按体重随机分为正常对照组(10只)和高脂造模组(70只)。正常对照组采用纯净水灌胃,高脂造模组灌胃给予高脂乳剂(猪油50g、胆固醇20g、吐温20ml、丙基硫氧嘧啶2g、丙二醇20ml、去氧胆酸钠4g制成400ml乳剂)1ml/100g。造模期间大鼠均自由饮水及摄食。连续造模4周后,大鼠眼眶静脉丛采血检测血清总胆固醇及甘油三酯含量。若高脂造模组血清总胆固醇及甘油三酯含量明显高于正常对照组(P〈0.05),表明高脂血症模型复制成功。
分组及给药:去除体重、总胆固醇、甘油三酯差异较大的大鼠,其余造模成功的大鼠按体重、总胆固醇、甘油三酯随机组(按照表1分组)。各组大鼠按10ml/kg灌胃给药,每天1次,连续4周;正常对照组和模型对照组给等容积纯净水。给药期间大鼠正常饮食。
指标检测:
1、体重:
每周定期称体重,比较用药前后体重变化情况。
2、总胆固醇、甘油三酯、尿酸检测:
末次给药一小时后,禁食不禁水12h,大鼠麻醉后腹主动脉取血,全自动生化分析仪测定血清总胆固醇(CHOL)、甘油三酯(TG)、尿酸(UA)。
3、低密度脂蛋白、高密度脂蛋白、同型半胱氨酸、白介素-6、氧化低密度脂蛋白、脂蛋白(a)检测:
腹主动脉取血,酶联免疫试剂盒测定低密度脂蛋白(LDL-C)、高密度脂蛋白(HDL-C);酶联免疫试剂盒测定同型半胱氨酸(HCY);酶联免疫试剂盒测定白介素-6;酶联免疫试剂盒测定氧化低密度脂蛋白(OxLDL);酶联免疫试剂盒测定脂蛋白(a)(LP-a)。
4、超氧化物歧化酶、丙二醛、一氧化氮、检测
腹主动脉取血,生化试剂盒测定超氧化物歧化酶(SOD)、丙二醛(MDA)、一氧化氮(NO)。
5、肝脏重量系数
取血完成后,腹主动脉放血处死大鼠,解剖取大鼠肝脏组织,称重,计算肝脏重量与体重的比值(肝脏重量系数=肝脏重量/体重*100%)。
6、肝脏病理学检查
放血处死大鼠,解剖取大鼠肝脏,用10%中性福尔马林液固定,制石蜡切片,切片厚度3-4μm,常规HE染色,于光学显微镜下观察肝脏和主动脉组织病理学变化,作出相关评价,具体评分标准见表2。
表2肝脏病理学检查评分标准
级别 | 评价标准 | 评分 |
0级 | 正常肝细胞 | 0 |
I级(轻度) | 变性细胞或泡沫细胞数〈25% | 1 |
II级(中度) | 变性细胞或泡沫细胞数≥25% | 2 |
III级(重度) | 变性细胞或泡沫细胞数≥50% | 3 |
结果:
1、对高脂血症大鼠体重的影响
适应性饲养后,按体重随机分组,后进行高脂灌胃造模。造模后(即给药前),与正常对照组相比较,模型对照组体重降低显著(P〈0.05),说明造模对大鼠体重影响较大,给药后期正常对照组和模型对照组大鼠体重不具有可比性。故给药后不进行两组比较。给药前,与模型对照组比较,各给药组大鼠体重无显著差异(P〉0.05),说明各给药组与模型对照组比较,大鼠体重具有可比性。给药第3周,与模型对照组比较,实施例1中药组合物低剂量组、实施例2-6大鼠体重增加显著(P〈0.05)。给药第4周,与模型对照组比较,各给药组大鼠体重增加显著(P〈0.05)。对比例1-2大鼠体重增加的效果不及实施例2,结果见表3。

2、对高脂血症大鼠血清总胆固醇(CHOL)、甘油三酯(TG)、低密度脂蛋白(LDL-C)、高密度脂蛋白(HDL-C)的影响。
与正常对照组相比较,模型对照组大鼠血清CHOL含量显著升高(P〈0.05);与模型对照组比较,给药组大鼠血清CHOL含量显著降低(P〈0.05)。与正常对照组比较,模型对照组大鼠血清TG含量显著降低(P〈0.05);与模型对照组大鼠比较,本发明实施例1-6各剂量组大鼠血清TG含量均具有统计学差异(P〈0.05)。
与正常对照组相比较,模型对照组大鼠血清LDL-C含量升高,但无统计学差异(P〉0.05);与模型对照组大鼠比较,本发明实施例1-6各剂量组大鼠LDL-C含量无统计学差异(P〉0.05)。与正常对照组比较,模型对照组大鼠血清HDL-C含量显著降低(P〈0.05);与模型对照组比较,本发明实施例1-6各剂量组HDL-C含量有升高趋势,无统计学差异(P〉0.05)。结果见表4。
表4
注:模型对照组与正常对照组比较,△(P〈0.05);给药组与模型对照组比较,*(P〈0.05)。
3、对高脂血症大鼠氧化低密度脂蛋白(OxLDL)、载脂蛋白A(apo-A)的影响。
与正常对照组相比较,模型对照组大鼠血清OxLDL含量升高(P〈0.05);与模型对照组比较,血脂康胶囊组大鼠血清OxLDL含量显著降低(P〈0.05)。结果见表5。
与正常对照组相比较,模型对照组大鼠血清apo-A含量无统计学差异(P〉0.05);与模型对照组比较,各给药组大鼠血清apo-A含量有升高趋势,无统计学差异(P〉0.05)。结果见表5。
下述指标单位分别为:OxLDL(μg/L)、apo-A(μg/mL)。
表5
注:模型对照组与正常对照组比较,△(P〈0.05);给药组与模型对照组比较,*(P〈0.05)。
3、对高脂血症大鼠肝脏重量系数及肝脏组织病理学形态的影响
与正常对照组相比较,模型对照组大鼠肝脏重量系数显著增加,具有统计学差异(P〈0.05);与模型对照组比较,各给药组大鼠肝脏重量系数显著降低(P〈0.05)。结果见表6。
与正常对照组相比较,模型对照组大鼠肝脏病理评分显著升高(P〈0.05);与模型对照组比较,各给药肝脏病理评分显著降低(P〈0.05),结果见表6。
表6
注:模型对照组与正常对照组比较,△(P〈0.05);给药组与模型对照组比较,*(P〈0.05)。
正常对照组大鼠肝脏组织无脂肪变性或见小量,肝脏的整体结构正常,肝细胞呈索状排列,无肿胀、坏死、胞浆无脂滴,细胞核可见位于细胞中央位置,未见脂肪变性。模型对照组中的脂肪空泡比正常对照组明显增多,呈重度脂肪变性,肝细胞内的细胞核被脂滴推挤向一侧,肝索解离,可见炎性浸润。实施例1的中药组合物(低、中、高剂量)和血脂康组中,在相同的放大倍数下可见,脂肪颗粒明显下降,肝细胞形态尚齐整,排列相对整齐,脂肪变性不太明显。
