Description

一种治疗缺血性脑中风的药物组合物及其制备方法与用途Medicine composition for treating ischemic stroke and preparation method and use thereof 技术领域Technical field
本发明属于药物领域，具体涉及一种治疗缺血性脑中风的药物组合物及其制备方法与用途。The invention belongs to the field of medicines, and particularly relates to a pharmaceutical composition for treating ischemic stroke and a preparation method and use thereof.
背景技术Background technique
脑卒中(Stroke)，又称脑中风或脑血管意外，是一种突然起病的脑血液循环障碍性疾病，是威胁人类健康的三大疾病之一，具有发病率高、死亡率高、致残率高、复发率高的特点。脑卒中是指在脑血管疾病的病人，因各种诱发因素引起脑内动脉狭窄，闭塞或破裂，而造成急性脑血液循环障碍，临床上表现为一过性或永久性脑功能障碍的症状和体征。脑卒中分为缺血性脑卒中和出血性脑卒中。近年来，我国的脑血管疾病患者逐年上升，以缺血性脑血管病最多见，约占20-25％。目前，我国每年新发脑中风300-350万人，死亡率高，存活者中约75％致残，5年复发率高达41％。Stroke, also known as stroke or cerebrovascular accident, is a sudden onset of cerebral blood circulation disorders, one of the three major diseases that threaten human health, with high incidence and high mortality. High residual rate and high recurrence rate. Stroke refers to patients with cerebrovascular disease, caused by various predisposing factors, such as cerebral artery stenosis, occlusion or rupture, resulting in acute cerebral circulation disorder, clinical manifestations of transient or permanent brain dysfunction symptoms and Signs. Stroke is divided into ischemic stroke and hemorrhagic stroke. In recent years, the number of patients with cerebrovascular diseases in China has increased year by year, with ischemic cerebrovascular disease the most common, accounting for 20-25%. At present, China has a new stroke of 300-3.5 million strokes per year, with a high mortality rate, and about 75% of the survivors are disabled. The 5-year recurrence rate is as high as 41%.
目前，我国已进入老年化社会，脑中风的发病率将有进一步增加的趋势。因此，研究脑中风尤其是缺血性脑中风的病理机制及治疗防护一直是医药界的重要任务。理论上，针对急性缺血或缺血再灌后细胞损伤的药物(神经保护剂)可保护脑细胞，提高对缺血缺氧损伤的耐受性，从目前的研究结果看，大多数在动物实验中具有疗效的药物，在临床试验中往往以失败告终。At present, China has entered an ageing society, and the incidence of stroke will further increase. Therefore, studying the pathological mechanism and therapeutic protection of stroke, especially ischemic stroke, has always been an important task in the medical field. In theory, drugs (neuroprotective agents) against cell damage after acute ischemia or ischemia-reperfusion can protect brain cells and improve tolerance to ischemia-anoxia injury. From the current research results, most of them are in animals. Drugs with efficacy in the experiment often end in failure in clinical trials.
中国专利文献CN103340890A公开了NADPH作为制备用于防治脑缺血性中风药物方面的应用。然而，未见NADPH和夹竹桃麻素联合应用治疗脑缺血性中风的报道。Chinese patent document CN103340890A discloses the use of NADPH as a medicament for the preparation of a medicament for preventing and treating cerebral ischemic stroke. However, there have been no reports of the combination of NADPH and oleandrin in the treatment of cerebral ischemic stroke.
因此，研究新型的治疗脑缺血性疾病的药物具有重要意义。 Therefore, it is of great significance to study new drugs for the treatment of cerebral ischemic diseases.

NADPH本身虽有一定的治疗脑卒中的作用，但是NADPH也可能被NADPH氧化酶利用产生氧化自由基而降低NADPH治疗脑卒中的疗效；夹竹桃麻素本身通过抑制NADPH氧化酶降低ROS产生而发挥治疗脑卒中的作用，但是它对已经产生的ROS以及由其它途径产生的ROS(如线粒体和琥珀酸脱氢酶)没有抑制作用，因此治疗脑卒中时也有局限性。Although NADPH itself has a certain role in the treatment of stroke, NADPH may also be used by NADPH oxidase to produce oxidative free radicals to reduce the efficacy of NADPH in the treatment of stroke; oleandrin itself plays a role in reducing ROS production by inhibiting NADPH oxidase. The role of stroke treatment, but it does not inhibit the ROS that have been produced and ROS produced by other pathways (such as mitochondria and succinate dehydrogenase), so there are limitations in the treatment of stroke.
本发明通过将NADPH和夹竹桃麻素联合给药，二者在特定的配比下共同作用，且作用于不同的靶点，既能清除ROS又能抑制ROS的产生。该药物组合物在采用适合于临床应用的给药途径条件下，能降低脑梗死体积，显著改善脑缺血小鼠行为障碍，减轻脑水肿，提高小鼠长期生存的能力和增强神经功能康复；而且，该药物组合物对缺血性脑中风的治疗效果显著优于二者单独给药对缺血性脑中风的治疗效果，NADPH和夹竹桃麻素联合给药具有协同增效的作用。这表明，该药物组合物具有治疗缺血性脑中风的作用，可以作为潜在的治疗缺血性脑中风的药物。 The invention combines NADPH and oleandrin, and the two work together in a specific ratio, and acts on different targets, both ROS can be eliminated and ROS can be inhibited. The pharmaceutical composition can reduce the volume of cerebral infarction under the condition of suitable administration route for clinical application, significantly improve the behavior disorder of mice with cerebral ischemia, reduce brain edema, improve the long-term survival ability of mice and enhance the recovery of nerve function; Moreover, the therapeutic effect of the pharmaceutical composition on ischemic stroke is significantly better than the therapeutic effect of the two drugs alone on ischemic stroke, and the combined administration of NADPH and oleandrin has a synergistic effect. This indicates that the pharmaceutical composition has an effect of treating ischemic stroke and can be used as a potential drug for treating ischemic stroke.

(2)实验方案(2) Experimental protocol
1)小鼠短暂性大脑中动脉阻塞模型建立1) Establishment of a transient middle cerebral artery occlusion model in mice
采用颈内动脉线栓法，稍加改进制备小鼠MCAO模型，小鼠以4％水合氯醛(400mg/kg)腹腔注射麻醉，我们采用线栓法制备缺血模型，分离颈总、颈外和颈内动脉，结扎劲外和颈总近心端，线栓(6023，Doccol Corporation,Redlands，USA)从颈外插入直到大脑前动脉起始端，阻断大脑中动脉供血。阻断血流2h后，拔出线栓实现再灌注。假手术组小鼠除不插线外，其余步骤均与缺血组和治疗组相同。整个手术过程中室温保持在22～25℃，采用自动控温加热垫将小鼠肛温控制在37±0.5℃。术后将动物置于放有清洁垫料的饲养盒中，自由饮水、进食。The mouse MCAO model was prepared with a slight improvement of the internal carotid artery suture method. The mice were anesthetized with 4% chloral hydrate (400 mg/kg). We used the suture method to prepare the ischemic model and separated the total neck and neck. And the internal carotid artery, the ligature and the total proximal end of the neck, the line plug (6023, Doccol Corporation, Redlands, USA) was inserted from the outside of the neck until the anterior end of the cerebral artery, blocking the blood supply to the middle cerebral artery. After blocking the blood flow for 2 hours, the plug was pulled out to achieve reperfusion. The sham-operated mice were the same as the ischemic group and the treatment group except that the mice were not inserted. The room temperature was maintained at 22-25 °C throughout the operation, and the temperature of the mouse was controlled at 37±0.5 °C using an automatic temperature-controlled heating pad. After the operation, the animals were placed in a feeding box with clean litter, and they were allowed to drink water and eat freely.
2)脑梗死体积测定2) Determination of cerebral infarction volume
脑缺血再灌注24h后将小鼠断头取脑，置冰箱(-20℃)数分钟，去掉嗅球、小脑和低位脑干，冠状切4刀分为5片(2mm)，脑片用红四氮唑(TTC)染色，染色液组成为：1.5mL1％TTC，0.1mL1mol/L K2HPO4，3.4mL生理盐水，37℃避光染色30min，正常组织呈红色，梗死组织为白色。 After 24 hours of cerebral ischemia-reperfusion, the mice were decapitated and placed in the refrigerator (-20 ° C) for several minutes to remove the olfactory bulb, cerebellum and lower brain stem. The coronary cut 4 knives were divided into 5 slices (2 mm), and the brain slices were red. tetrazolium (TTC) staining, staining solution consisting of: 1.5mL1% TTC, 0.1mL1mol / LK 2 HPO 4, 3.4mL saline, 37 [deg.] C dark staining 30min, normal tissue red, white infarcted tissue.
4％甲醛固定两天后，用滤纸吸干液体再取出脑梗死组织，以梗死脑组织重量占总大脑重量的百分比作为脑梗死体积的指标。用Sigma Pro5.0软件计算脑梗塞面积所占百分比。After fixing the 4% formaldehyde for two days, the liquid infiltrated with the filter paper and then the cerebral infarcted tissue was taken out, and the percentage of the infarcted brain tissue to the total brain weight was used as an indicator of the infarct volume. The percentage of cerebral infarction area was calculated using Sigma Pro 5.0 software.
3)神经症状评分3) Neurological symptom score
小鼠脑缺血再灌注24h后，由一不了解分组情况的观察者按照五分制评分标准对小鼠进行神经行为障碍评分：0分：无神经功能缺损症状；1分：不能完全伸展对侧前肢；2分：行走时向对侧旋转，出现“追尾”现象；3分：站立不稳，向对侧倾倒；4分：不能自发行走，意识障碍。After 24 hours of cerebral ischemia-reperfusion in mice, the neurobehavioral scores of the mice were scored according to the five-point scale by an observer who did not understand the grouping: 0 points: no neurological deficit symptoms; 1 point: not fully extended Side forelimb; 2 points: Rotating to the opposite side while walking, there is a phenomenon of "tail-catching"; 3 points: standing unstable, dumping to the opposite side; 4 points: unable to self-issue, consciousness disorder.
4)大脑含水量测定4) Determination of brain water content
脑缺血再灌注24h后将小鼠断头取脑，去掉嗅球、小脑和低位脑干，称取大脑湿重，107℃烘烤48h后称干重，大脑含水量百分比＝(湿重-干重)/湿重×100％。After 24 hours of cerebral ischemia-reperfusion, the mice were decapitated and the brain was removed. The olfactory bulb, cerebellum and low brainstem were removed. The wet weight of the brain was weighed. After drying for 48 hours at 107 °C, the dry weight was calculated. The percentage of brain water content = (wet weight - dry Heavy) / wet weight × 100%.
5)神经功能测试5) Neurological function test
I、动物模型的制作I. Production of animal models
选取体重在23-28g的雄性ICR小鼠，作脑缺血2h再灌注手术。该动物模型脑缺血时间长，死亡率高，注意及时补足动物数。Male ICR mice weighing 23-28 g were selected for cerebral ischemia 2h reperfusion. The animal model has a long cerebral ischemia time and a high mortality rate, and pay attention to the number of animals in time.
II、运动功能试验II. Exercise function test
转子杆测试(Rota-rod test)在转子杆上保持平衡需要本体觉、位置觉及微调运动能力。该测试要求小鼠在匀速旋转杆上保持平衡，并记录其在转棒上的运动时间及跌落时间得转棒旋转速度。测试中缓慢的加速限制了个体间表现的差异性。Rota-rod test balancing on the rotor bar requires proprioception, positional awareness, and fine-tuning. This test requires the mouse to maintain a balance on the uniform rotating rod and record its movement time on the rotating rod and the falling time to rotate the rod. The slow acceleration in the test limits the differences in performance between individuals.
所需仪器与材料包括：(1)仪器：滚轮轴心的直径为5cm左右，由坚固的塑料制作而成，外面包裹灰色的橡胶泡沫，管宽约5cm，这个仪器可以 在300s内从4转/min加速到40转/min；(2)秒表；(3)50％酒精；(4)纸巾。The required instruments and materials include: (1) Instrument: The diameter of the roller shaft is about 5cm. It is made of sturdy plastic and is covered with gray rubber foam. The tube is about 5cm wide. This instrument can be used. Accelerate from 4 rpm to 40 rpm in 300 s; (2) stopwatch; (3) 50% alcohol; (4) paper towel.
在测验的时候，把小鼠放在他们自己的笼子里，让它们在测试房间内适应15min(适应环境阶段)。整个测试是由间隔15min的三次试验组成。在测验阶段前没有训练阶段。它可以在同一次试验时直接对下一批小鼠进行操作。仪器设定为在300s内从4转/min加速到40转/min。仪器在开始前以4转/min的恒速运转。At the time of the test, the mice were placed in their own cages and allowed to acclimate for 15 min in the test room (adapted to the environmental phase). The entire test consisted of three trials at intervals of 15 min. There is no training phase before the test phase. It can be operated directly on the next batch of mice in the same experiment. The instrument was set to accelerate from 4 rpm to 40 rpm in 300 s. The instrument was operated at a constant speed of 4 rpm before starting.
III、学习记忆的行为学试验—习迷宫实验(Y-maze test)III. Behavioral test of learning and memory - Y-maze test
Y型电迷宫3条臂的尽头均有l灯，底部是电网，其中只有1条臂尽头的灯发出亮光，此时该臂底部电网无电流通过，即为安全区；另两臂的灯不亮，底部电网通电(约50V)，为非安全区；安全区与非安全区随机改变。There are l lights at the end of the 3 arms of the Y-type electric maze, and the bottom is the power grid. Only the light at the end of one arm emits light. At this time, the current at the bottom of the arm has no current, which is the safe area; the lights of the other two arms are not. Light, the bottom grid is energized (about 50V), which is a non-safe area; the safe area and the non-safe area are randomly changed.
实验开始时，将动物放入迷宫中任一臂中适应2～3min；然后将其他任一臂的信号灯打开作为条件刺激，经l s延迟后，灯不亮的两臂通电(非条件刺激)；当动物逃避电击至安全区后，灯亮持续15s，然后熄灯休息45s，即完成1次操作并记录所用时间；然后再开始下一次操作。At the beginning of the experiment, the animal was placed in any arm of the maze for 2 to 3 minutes; then the signal of any other arm was turned on as a conditional stimulus, and after 1 s delay, the two arms of the lamp were not energized (unconditioned stimulus). When the animal evades the electric shock to the safe area, the light is on for 15s, then the light is turned off and rested for 45s, that is, one operation is completed and the time used is recorded; then the next operation is started.
6)数据统计与分析6) Data statistics and analysis
数据均以均数±SD(Mean±SD)表示，统计分析采用单因素方差分析(one-way ANOVA)，p<0.05为统计学差异有显著性。Data were expressed as mean ± SD (Mean ± SD), and statistical analysis was performed by one-way ANOVA. p < 0.05 was considered statistically significant.
(4)实验结果NADPH联合夹竹桃麻素侧脑室注射和静脉注射给药对缺血性脑中风小鼠脑梗死体积的影响如图1(a)、1(b)所示。(4) Experimental results The effects of NADPH combined with oleandrin injection on the cerebral infarction volume of ischemic stroke in mice are shown in Fig. 1(a) and 1(b).
由图1(a)、1(b)可知，与模型组相比，侧脑室注射NADPH(1mg/kg)联合夹竹桃麻素(4mg/kg)用药组显著降低了小鼠脑缺血再灌注24h后脑梗死体积(p<0.05)；和静脉注射NADPH(1mg/kg)联合夹竹桃麻素(4mg/kg)NADPH联合夹竹桃麻素用药组都明显著降低了小鼠脑缺血再灌注24h后脑梗死体积(p<0.05，p<0.01)；静脉注射NADPH(7.5mg/kg)联合 夹竹桃麻素(2.5mg/kg)用药组也显著降低了小鼠脑缺血再灌注24h后脑梗死体积(p<0.001)。但是相互比较三组的结果可以发现，静脉注射NADPH(1mg/kg)联合夹竹桃麻素(4mg/kg)产生的效果比脑室注射的差，差异有显著性(p<0.05)；静脉注射NADPH(7.5mg/kg)联合夹竹桃麻素(2.5mg/kg)产生的效果比静脉注射NADPH(1mg/kg)联合夹竹桃麻素(4mg/kg)产生的效果好，差异有显著性(p<0.01)。因此，单独静脉注射NADPH(1mg/kg)没有显著降低脑梗死体积的作用，单独静脉注射夹竹桃麻素(2.5mg/kg)只有轻微的治疗效果，所以静脉注射NADPH(7.5mg/kg)联合夹竹桃麻素(2.5mg/kg)效果更有临床应用价值。As can be seen from Fig. 1(a) and Fig. 1(b), the injection of NADPH (1 mg/kg) combined with oleandrin (4 mg/kg) in the lateral ventricle significantly reduced the cerebral ischemia in mice compared with the model group. Cerebral infarction volume after 24h perfusion (p<0.05); and intravenous injection of NADPH (1mg/kg) combined with oleandrin (4mg/kg) NADPH combined with oleandrin significantly reduced cerebral ischemia in mice Cerebral infarction volume after 24 hours of reperfusion (p<0.05, p<0.01); intravenous NADPH (7.5mg/kg) combination The oleandrin (2.5 mg/kg) treatment group also significantly reduced the volume of cerebral infarction after 24 h of cerebral ischemia-reperfusion in mice (p<0.001). However, comparing the results of the three groups, the effect of intravenous NADPH (1mg/kg) combined with oleandrin (4mg/kg) was worse than that of ventricular injection (p<0.05); intravenous injection NADPH (7.5mg/kg) combined with oleandrin (2.5mg/kg) produced better results than intravenous NADPH (1mg/kg) combined with oleandrin (4mg/kg). The difference was significant. Sex (p<0.01). Therefore, intravenous NADPH alone (1 mg/kg) did not significantly reduce the volume of cerebral infarction. Intravenous injection of oleandrin (2.5 mg/kg) had only a slight therapeutic effect, so intravenous NADPH (7.5 mg/kg) The combination of oleandrin (2.5mg/kg) has more clinical application value.
夹竹桃麻素夹竹桃麻素夹竹桃麻素NADPH联合夹竹桃麻素静脉注射给药对缺血性脑中风小鼠脑梗死体积的影响如图2(a)、2(b)所示。The effects of oleandrin, oleandrin, oleander, NADPH, and oleandrin on the infarct volume of mice with ischemic stroke are shown in Fig. 2(a) and 2(b). Shown.
由图2(a)、2(b)可知，与模型组相比，NADPH组和夹竹桃麻素组都明显降低了小鼠脑缺血再灌注24h后脑梗死体积(p<0.01)；NADPH联合夹竹桃麻素组进一步降低小鼠脑梗死体积(p<0.001)；与单独用药组相比，联合用药组有显著性差异(p<0.05)。这表明，NADPH、夹竹桃麻素以及两者联合用药均可降低脑缺血性中风小鼠脑梗死体积，两药合用的效果优于单独使用。2(a) and 2(b), compared with the model group, both the NADPH group and the oleandrin group significantly reduced the volume of cerebral infarction after 24 hours of cerebral ischemia-reperfusion in mice (p<0.01); NADPH The combined oleandrin group further reduced the volume of cerebral infarction in mice (p<0.001); there was a significant difference (p<0.05) between the combination group and the drug alone group. This indicates that NADPH, oleandrin and the combination of the two can reduce the volume of cerebral infarction in mice with cerebral ischemic stroke, and the combined effect of the two drugs is better than that of the single use.
NADPH联合夹竹桃麻素静脉注射给药对缺血性脑中风小鼠神经症状的影响如图3所示。The effect of intravenous administration of NADPH combined with oleandrin on neurological symptoms in mice with ischemic stroke is shown in Figure 3.
由图3可知，与模型组相比，NADPH组和夹竹桃麻素组明显降低小鼠脑缺血再灌注24h后神经症状评(p<0.05)；两者联合应用则进一步降低了小鼠神经症状评分(p<0.01)；与单独用药组相比，联合用药组有显著性差异(p<0.05)。这表明，NADPH、夹竹桃麻素以及两者联合应用均可改善脑缺血性中风小鼠的神经症状，两药合用的效果优于单独使用。As can be seen from Figure 3, compared with the model group, the NADPH group and the oleandrin group significantly reduced the neurological symptoms after 24 hours of cerebral ischemia-reperfusion in mice (p<0.05); the combination of the two further reduced the mice. Neurological symptom scores (p < 0.01); there was a significant difference (p < 0.05) in the combination group compared with the drug alone group. This indicates that NADPH, oleandrin and the combination of both can improve the neurological symptoms of mice with cerebral ischemic stroke.
