Description
技术领域
本发明属于医药类领域,尤其涉及一种以多种中药材为原料可以维持心肌梗死患者病情长期稳定、有效提高患者心脏储备能力的治疗心肌梗死的中成药及其制备方法。
背景技术
心肌梗死是冠状动脉粥样硬化性心脏病的一种临床类型,是心肌的缺血性坏死,是在光状动脉病变的基础上,发生冠状动脉血供急剧减少或中断,使相应的心肌严重而持久地急性缺血所致,属冠心病的严重类型,也是严重危害人类生命健康的常见病,心肌梗死以中医论治属于胸痹范畴,临床上有剧烈而较持久的胸骨后疼痛、发热、白细胞增多、红细胞沉降率加快、血清心肌酶活力增高及进行性心电图变化,可发生心率失常、休克或心力衰竭,目前中西医对心肌梗死的治疗还没有很好的治疗办法。
现代医学对心肌梗死的治疗方法通常是对患者进行监护并进行一般性的治疗,即镇静止痛、调整血容量、灌注治疗、缩小梗死面积、抗心律失常。但西药治疗会给患者带来副作用,且短期内易复发。中医通过多种中药材的合理配伍,制成片剂,达到维持心肌梗死患者病情长期稳定、有效提高患者心脏储备能力的效果。
发明内容
本发明的目的在于克服现有西医对治疗心肌梗死中存在的副作用大,且短期内易复发,而提供一种维持心肌梗死患者病情长期稳定、有效提高患者心脏储备能力的治疗心肌梗死的中成药及其制备方法,以减轻心肌梗死患者的痛苦。
本发明的目的是这样实现的:
一种治疗心肌梗死的中成药,它是由下述重量份数的原料配制而成:熟地黄100~140份、巴戟天80~120份、川芎120~180份、当归100~140份、石斛80~120份、肉桂10~50份、甘草10~50份。
进一步它是由下述重量份数的原料配制而成:熟地黄110~130份、巴戟天90~110份、川芎140~160份、当归110~130份、石斛90~110份、肉桂20~40份、甘草20~40份。
具体的它是由下述重量份数的原料配制而成:熟地黄120份、巴戟天100份、川芎150份、当归120份、石斛100份、肉桂30份、甘草30份。
一种治疗心肌梗死的中成药的制备方法如下:
步骤1)、按照以上权利要求中所述原料的重量份数取出各种原料,将石斛分为5份,取其中的3份与熟地黄、巴戟天、川芎、当归、肉桂、甘草混合,粉碎,过120目筛得混合粉末,将剩下的2份石斛粉碎,过120目筛得石斛粉末,备用;
步骤2)、将步骤1)中所述的混合粉末采用双提法连续回流提取2次,第一次加入水的重量为步骤1)中所述的混合粉末的重量的8倍,第二次加入水的重量为步骤1)中所述的混合粉末的重量的6倍,用电热套加热,每次高温270~300℃烧开后,低温150~200℃维持沸腾30分钟,用挥发油提取器提取挥发油,合并2次水煎液,过滤得水提液,离心机4000r/min,离心15分钟得上清液;
步骤3)、将步骤2)中所述的上清液用旋蒸仪蒸发得含水量为60%的浸膏,干燥得干浸膏;
步骤4)、将步骤3)中所述的干浸膏与备用的2份石斛粉末混合,研磨,过120目筛得混合粉末颗粒;
步骤5)、将步骤4)中所述的混合粉末颗粒与95%乙醇按容量比为3:1混合制得软材,过14目筛,在-0.1MPa、20℃环境中烘干得含水量为5%的颗粒;
步骤6)、将步骤5)中所述的颗粒与滑石粉按重量比为100:3的比例混合,将步骤2)中所述的挥发油与95%乙醇按体积比为1:4混合喷于颗粒中,混匀,过14目筛,压片得片重为0.5克的药片。
本发明具有以下优点:
本发明中各种药材使用配伍合理,经科学方法制备、药效稳定、使用方便,具有改善患者的运动耐量、延长患者的运动总时间、提高患者心脏能力等功效。具有制备工艺简单、没有任何毒副作用、使用方便等优点,经临床验证对心肌梗死有稳定的疗效。
本发明无毒副作用,所采用的配方中的药物药理为:熟地黄,味甘,性微温,归肝、肾经,用于滋阴补血、益精填髓、肝肾阴虚、腰膝酸软、骨蒸潮热、盗汗遗精、内热消渴、血虚萎黄、心悸怔忡、月经不调、崩漏下血、眩晕、耳鸣、须发早白;巴戟天,味甘、辛,性微温,归肾、肝经,用于补肾阳、强筋骨、祛风湿、阳痿遗精、宫冷不孕、月经不调、少腹冷痛、风湿痹痛、筋骨痿软;川芎,味辛,性温,归肝、胆、心包经,用于活血行气、祛风止痛、月经不调、经闭痛经、症瘕腹痛、胸胁刺痛、跌扑肿痛、头痛、风湿痹痛;当归,味甘、辛,味温,归肝、心、脾经,用于补血活血、调经止痛、润肠通便、血虚萎黄、眩晕心悸、月经不调、经闭痛经、虚寒腹痛、肠燥便秘、风湿痹痛、跌扑损伤、痈疽疮疡、经闭痛经、风湿痹痛、跌扑损伤;石斛,味甘,性微寒,归胃、肾经,用于益胃生津、滋阴清热、阴伤津亏、口干烦渴、食少干呕、病后虚热、目暗不明;肉桂,味辛、甘,性大热,归肾、脾、心、肝经,用于补火助阳、引火归源、散寒止痛、活血通经、阳痿、宫冷、腰膝冷痛、肾虚作喘、阳虚眩晕、目赤咽痛、心腹冷痛、虚寒吐泻、寒疝、奔豚、经闭、痛经;甘草,味甘,性平,归心、肺、脾、胃经,用于补脾益气、清热解毒、祛痰止咳、缓急止痛、调和诸药、脾胃虚弱、倦怠乏力、心悸气短、咳嗽痰多、脘腹、四肢挛急疼痛、痈肿疮毒、缓解药物毒性、烈性。

(一)治疗心肌梗死的中成药对心肌梗死模型大鼠内皮功能及血管新生影响
目的:观察治疗心肌梗死的中成药对心肌梗死大鼠内皮功能及血管新生的影响,探讨治疗心肌梗死的中成药对心肌梗死大鼠模型心肌保护的机制。
方法:采用冠状动脉左前降支结扎法制备心肌梗死模型大鼠。健康SD大鼠60只,随机分为假手术组、模型组、治疗心肌梗死的中成药低剂量组、治疗心肌梗死的中成药中剂量组、治疗心肌梗死的中成药高剂量组,每组大鼠12只。术后假手术组及模型组每日予生理盐水灌胃,其余各组每日分别予相应药物灌胃,均治疗14天。临床观察:分别在给药7天、14天时检测血清一氧化氮合成酶(eNOS)、内皮素-1(ET-1)、血管性血友病因子(vonWillebrandFactorvWF)、血管内皮生长因子(VEGF),给药14天处死大鼠取心脏组织,HE染色行梗死区形态学观察并测量梗死面积,免疫组化法检测梗死边缘区微血管(microvascularMVC)计数。结果:给药第7天,与假手术组比较,模型组、低、中、高剂量组eNOS、内皮素-1(ET-1)、血管性血友病因子(vonWillebrandFactorvWF)、VEGF均升高,差异有统计学意义(P<0.05);各药物治疗组与模型组比较VEGF及eNOS均升高,差异有统计学意义(P<0.05);低、中、高剂量组组间两两比较,差异有统计学意义(P<0.05)。给药第14天,与模型组比较,各药物治疗组VEGF及eNOS均升高,差异有统计学意义(P<0.05);各药物治疗组ET-1与vWF均下降,中、高剂量组组间两两比较,差异有统计学意义(P<0.05);与模型组比较,各药物治疗组MVC计数升高,差异有统计学意义(P<0.05)。
结论:1、治疗心肌梗死的中成药对心肌梗死模型大鼠心肌细胞具有保护作用;2、治疗心肌梗死的中成药对心肌梗死模型大鼠心肌细胞的保护机制可能是促进eNOS激活、提高VEGF表达、抑制ET-1及vWF的表达,从而保护血管内皮细胞,促进梗死边缘区新生血管形成;3、治疗心肌梗死的中成药在保护心肌梗死大鼠内皮细胞及促进新生血管形成方面有一定的量效关系。
(二)治疗心肌梗死的中成药对阳虚水泛型心衰的心肌重构相关因子作用,及对患者临床疗效和生活质量的影响

2、采用SPSS13.0进行统计学分析,相关分析用直线回归分析
结果:1、经统计学分析,两组患者的一般资料包括性别、年龄、治疗前中医症候积分、Lee氏心衰积分、生活质量积分以及病情严重程度、肝肾功能等安全性指标,差异无统计学意义,具有可比性;2、两组治疗后症状均有改善,与治疗前比较均有统计学意义(P<0.05);治疗后治疗组症状改善程度优于对照组,有统计学意义(P<0.05);3、理化检查:经治疗后两组的神经激素系统的指标均有所下降,两组的心脏超声指标均有所好转,与治疗前比较均有统计学意义(P<0.05);治疗后治疗组神经激素系统的指标下降水平,心脏超声指标好转水平优于对照组,有统计学意义(P<0.05);4、安全性指标检查:治疗前后两组ALT均无明显变化,无统计学意义(P>0.05),治疗组:BUN、Cr治疗后较治疗前下降,与对照组治疗后相比亦下降,差异均有统计学意义(P<0.05)。
结论:1、治疗心肌梗死的中成药联合西医基础治疗及西医基础治疗对阳虚水泛型慢性心衰患者的症状改善均有作用,并提高患者的生活质量;2、治疗心肌梗死的中成药联合西医基础治疗及西医基础治疗对阳虚水泛型慢性心衰的心肌重构相关因子均趋向良陛变化,对心肌重构均有改善作用;3、治疗心肌梗死的中成药联合西医基础治疗组对阳虚水泛型慢性心衰患者的临床症状改善、生存质量的提高和心肌重构的改善明显优于单纯西医基础治疗组;4、治疗心肌梗死的中成药能够改善阳虚水泛型慢性心衰患者的肾功能。
