Description
技术领域
本发明涉及动物模型技术领域,具体地说,涉及一种NERD病证结合模型及其构建方法和应用。
背景技术
NERD(Non-erosivereflux disease)是指非糜烂性胃食管反流病,属于胃食管反流病的一种。非糜烂性胃食管反流病患者的食管通常并没有糜烂性的病变,在胃镜下观察,患者的食管黏膜较为完整,没有明确的糜烂或溃疡等黏膜损伤。
非糜烂性胃食管反流病约占胃食管反流病的50%~70%,该病临床主要表现为反酸、烧心、胃脘隐痛、痞满胀闷、纳差、乏力、大便稀溏等症状。中医认为NERD属于“嘈杂”“吞酸”范畴,病位在胃,涉及肝、胆、脾、肺,肝胆失于疏泄,脾失健运胃失和降,肺失宣肃,情志不畅,肝气郁滞,横逆犯胃,则胃气上逆,上犯食管,导致反酸、烧心。该病主要病机是胃气上逆,气机升降失常所致。
目前NERD的治疗常以PPI(质子泵抑制剂)作为首选药,但部分患者对PPI的反应性差,研究表明应用质子泵抑制剂仅能治愈50%-60%非糜烂性胃食管反流病患者的反流症状。临床上,对PPI反应差的患者,即使换用多种PPI,仍不能有效控制症状,对于伴有焦虑抑郁状态的患者尤为明显,导致NERD复发率高。为控制症状、预防复发,通常采取长时间应用PPI进行维持治疗,但强力抑酸会延长胃排空,影响患者食欲,导致消化不良,降低患者生活质量,同时长期维持PPI的治疗方法费用昂贵,增加了患者的经济负担,而且仍无法避免停药后病情复发的风险,因此寻求更有效更安全的治疗NERD的药物具有非常重要的意义。
中国专利申请:CN201410594964.3公开了一种治疗非糜烂性胃食管反流病的药物及其应用,由柴胡10~14份、枳壳10~14份、黄连2~4份、吴茱萸2~4份、金沸草10~14份、代赭石13~17份、焦山栀4~8份、延胡索10~14份、川楝子7~11份、煅瓦楞27~33份、生姜2~4份、甘草4~8份。
发明内容
本发明的目的是针对现有技术中的不足,一种NERD病证结合模型及其构建方法和应用。
为实现上述目的,本发明采取的技术方案是:
第一方面,本发明提供了一种治疗消化道疾病的中药组合物,由以下重量份的原料药制成:柴胡3-15份、香附6-18份、枳壳6-18份、旋覆花6-18份、代赭石9-21份、黄连1-5份、吴茱萸1-5份、焦山栀3-15份、煅瓦楞20-40份、珍珠母9-21份、延胡索3-15份、黄精9-21份、生姜1-5份。

更优选地,所述中药组合物由以下重量份的原料药制成:柴胡9份,香附12份,枳壳12份,旋覆花12份,代赭石15份,黄连3份,吴茱萸3份,焦山栀9份,煅瓦楞30份,珍珠母15份,延胡索9份,黄精15份,生姜3份。
所述的中药组合物的药剂是片剂、胶囊剂、颗粒、口服液、合剂或糖浆剂。
第二方面,本发明提供了如上所述的中药组合物在制备治疗消化道疾病药物中的应用。
优选地,所述消化道疾病为非糜烂性胃食管反流病、反流性食管炎、难治性胃食管反流病。
第三方面,本发明提供了一种NERD病证结合模型的建立,参考Tugay幽门半结扎联合贲门肌撕裂的造模方法复制酸反流手术模型,术前24小时禁食不禁水,戊巴比妥腹腔麻醉,沿腹中线纵行剪开,剪断肝胃韧带及胃周围筋膜,将胃全部提出,充分暴露胃及幽门,用4-0尼龙线将幽门半结扎,注意避开血管;结扎胃左动脉,以防损伤血管引起出血,自食管胃结合处开始向上钝性分离,长度约1cm,避免损伤食管内膜,并用抗生素配合生理盐水湿润腹腔,防止粘连,结束后关腹。术后孤笼饲养,24小时内禁食不禁水,术后1天给予少量饮食,第2-3天观察有无腹部渗血、精神萎靡等情况。7天后开始心理应激,大鼠单笼孤养是心理应激的前提,在此基础上进行慢性温和不可预见性刺激(Chronic Unpredictable MildStimulation,CUMS),主要包括强迫游泳试验、束缚试验、昼夜颠倒、禁食、禁水,每天随机选取一种刺激,共14天。
君臣佐使配伍关系
君药:柴胡、香附、枳壳。柴胡、香附疏肝解郁,行气止痛,疏肝理气,以防肝火犯胃,枳壳理气宽中,既助柴胡解肝经之郁滞,又理气化痰宽中,助脾升胃降,促使脾胃恢复正常功能。
臣药:旋覆花、代赭石。旋复花、代赭石、生姜取自旋覆代赭汤,旋覆花利气消痰,降逆止嗳,代赭石平肝潜阳,重镇降逆,既平肝以防肝火伐胃,又可降逆以防胃气上逆。
佐药:黄连、吴茱萸、焦山栀。黄连苦寒,可泻肝胃之火,吴茱萸辛、苦、热,疏肝解郁,降逆止呕,又可防黄连寒凉伐胃,焦山栀清三焦之热,以防木从火化,化腐作酸。
使药:煅瓦楞、珍珠母、延胡索、黄精。煅瓦楞性咸平,咸能软坚散结,消痰化瘀,煅用可以制酸止痛;珍珠母平肝潜阳,清肝热;延胡索行气止痛缓解患者症状;黄精益气健脾,滋脾阴以防燥热之品伤阴,同时它也是治疗嘈杂的良药。
本发明优点在于:
该中药组合物符合君臣佐使的配伍,诸药合用,共达疏肝理气,和胃降逆之效,达到治疗疾病的目的。

2.1治疗方案
2.1.1一般治疗
抬高床头;控制饮食,睡前不宜进食,避免食用辛辣刺激之品,限制生冷瓜果的摄入,避免服用可导致食管下括约肌(LES)松弛的药物及食物(巧克力、咖啡、抗胆碱能药物等);避风寒,畅情志,适当运动。

(2)西药组:雷贝拉唑肠溶片:每次10mg,每天两次,餐前半小时口服,连用八周。
疗程结束后评定疗效。
3观察指标
3.1临床症状积分
表1临床症状积分量表
按照患者临床症状轻重分为无、轻、中、重四级,无表示没有出现此类症状;轻表示偶有发生,每日<1次;中表示每日发生1-3次;重表示频发,影响工作和休息。其中主要症状积分分别为0分、2分、4分、6分,其他症状积分分别为0分、1分、2分、3分。
3.2临床有效率判定
临床疗效判定分痊愈、显效、有效、无效四个等级,具体如下:
(1)痊愈:烧心、反酸等症状消失,临床症状积分减少≥95%。
(2)显效:烧心、反酸等症状基本消失,虽偶有症状但很快消失,症状积分减少≥70%。
(3)有效:烧心、反酸等症状虽未消失,但比之前缓解,症状积分减少≥30%。
(4)无效:烧心、反酸等症状仍然存在,程度也还未减轻,症状积分减少不及30%。
有效率=(治疗前临床症状积分-治疗后临床症状积分)/治疗前临床症状积分×100%。
4统计方法
采用SPSS16.0软件进行统计分析,以p≤0.05为差别有统计学意义。
计量资料:若数据服从正态分布或近似正态分布且方差齐,统计描述用均数±标准差表达,统计推断用采用t检验或方差分析等;若数据不服从正态分布,统计描述用中位数(M)、最小值和最大值(min,max)表达。统计推断采用秩和检验。
计数资料:统计描述可采用、构成比、率等表示,统计推断用χ2检验或fisher's检验;数据资料呈分类属性不同的有序资料,宜用秩和检验、等级相关分析等。

2.方法
2.1病证结合模型建立
参考Tugay幽门半结扎联合贲门肌撕裂的造模方法复制酸反流手术模型,术前24小时禁食不禁水,戊巴比妥腹腔麻醉,沿腹中线纵行剪开,剪断肝胃韧带及胃周围筋膜,将胃全部提出,充分暴露胃及幽门,用4-0尼龙线将幽门半结扎,注意避开血管;结扎胃左动脉,以防损伤血管引起出血,自食管胃结合处开始向上钝性分离,长度约1cm,避免损伤食管内膜,并用抗生素配合生理盐水湿润腹腔,防止粘连,结束后关腹。术后孤笼饲养,24小时内禁食不禁水,术后1天给予少量饮食,第2-3天观察有无腹部渗血、精神萎靡等情况。7天后开始心理应激,大鼠单笼孤养是心理应激的前提。在此基础上进行慢性温和不可预见性刺激(Chronic Unpredictable Mild Stimulation,CUMS)。
2.2分组
45只已造模好的大鼠,术后的第2-3天死亡5只,死亡原因:食管破裂(2只)、幽门梗阻(3只),剩余40只,随机分为本发明组一、本发明组二、模型组、对照组一、对照组二五组,以每组8只进行检测统计。
2.3主要操作方法
包括强迫游泳试验、束缚试验、昼夜颠倒、禁食、禁水,每天随机选取一种刺激,共14天。(图2)
①强迫游泳试验:将大鼠放入高60cm,直径30cm,水深约30cm左右的柱状玻璃桶中,以大鼠漂浮不能站立,跳跃无法跳出水槽为准,水温为20℃左右,时间15min。
②束缚试验:用大鼠固定器将大鼠固定,限制大鼠的头部活动和进退,但不能对大鼠造成损伤,也不能影响大鼠的呼吸和排泄,固定6小时后放回饲养笼中。
③黑白颠倒:早七点将大鼠放入暗室,使大鼠处于黑暗中12小时,晚七点将大鼠放入开灯的房间,照射12小时,共计24小时。
④禁食:禁食24小时,从早晨八点至第二天早晨八点。
⑤禁水:禁水24小时,从早晨八点至第二天早晨八点。
