血塞通软胶囊治疗脑梗死临床观察

目的观察血塞通软胶囊治疗脑梗死的疗效。方法治疗组35例以血塞通软胶囊口服,并根据病情配合一般综合疗法(必要的抗感染、纠正水电解质紊乱)。对照组30例以单纯综合疗法治疗。分别观察2组症状、积分及血液流变学改变。结果治疗组基本治愈6例(17%),显效13例(37%),有效14例(40%),无变化2例(6%),总有效率94%;对照组基本治愈3例(10%),显效4例(13%),有效10例(33%),无变化及恶化12例(4%),死亡1例(3%),总有效率57%;2组总有效率比较有显著性差异(P<0.01)。治疗组血液流变学改善也较对照组明显(P均<0.01),且未见明显不良反应。结论血塞通软胶治疗脑梗死安全有效。

血塞通软胶囊对家兔眼球微循环障碍及血瘀大鼠血液流变性的影响

目的:观察血塞通软胶囊对家兔眼球结膜微循环障碍及血瘀大鼠血液流变学指标的影响。方法:采用耳缘静脉注射10%高分子右旋糖苷的方法造成家兔眼球结膜微循环障碍,观察血塞通软胶囊对家兔眼球结膜微循环中微血管管径、血液流态、毛细血管开放数的影响;采用冰水浴联合皮下注射盐酸肾上腺素的方法制备血瘀大鼠模型,观察血塞通软胶囊对血瘀大鼠血液流变学指标的影响。结果:血塞通软胶囊27mg/kg、13.5mg/kg、6.75mg/kg能明显增加家兔眼球结膜的血管管径,减少血管管径的变化率,抑制血管管径减小,同时能明显增加血液流速,血塞通软胶囊27mg/kg、13.5mg/kg也能显著增加毛细血管开放数P<0.05。另外,血塞通软胶囊56mg/kg、28mg/kg、14mg/kg均能明显降低血瘀证大鼠的全血粘度,减少全血高切、中切、低切的粘度值,显著减少红细胞电泳的时间。结论:血塞通软胶囊可改善微循环及血液流变学指标,其活血化瘀作用有利于视网膜中央静脉栓塞的治疗。

Effects of Xuesetong Soft Capsules(血塞通软胶囊) on angiogenesis and VEGF mRNA expression in ischemic myocardium in rats with myocardial infarction

OBJECTIVE:To observe the effects of Xuesetong Soft Capsules(血塞通软胶囊,Notoginseng total saponin) on angiogenesis and vascular endothelial growth factor(VEGF) mRNA expression in ischemic myocardium of rats with myocardial infarction.METHODS:The left coronary artery of rats was ligated to establish the animal model of acute myocardial infarction.Rats were randomly divided into Xuesetong Soft Capsule,Shexiangbaoxin Pill(positive control),model(negative control) and sham operation groups.After 6 weeks,microvessel count(MVC),microvessel density(MVD) and VEGF mRNA expressioninischemicmyoc ardium were evaluated.RESULTS:MVC and MVD in the myocardial infarct border area in model,Shexiangbaoxin Pill and Xuesetong Soft Capsule groups significantly increased compared with those of the sham operation group(P<0.05).MVC and MVD in the myocardial infarct border area in Xuesetong Soft Capsule and Shexiangbaoxin Pill groups significantly increased compared with those of the model group(P<0.05).No significant differences between Xuesetong Soft Capsule and Shexiangbaoxin Pill groups were observed(P>0.05).The model group showed signifi-cantly higher VEGF mRNA expression than that in the sham operation group(P<0.05).Xuesetong Soft Capsule and Shexiangbaoxin Pill groups showed significantly higher VEGF mRNA expression than that of the model group(P<0.05).No significant difference between Xuesetong Soft Capsule and the Shexiangbaoxin Pill groups was observed(P>0.05).CONCLUSION:Xuesetong Soft Capsules promote angiogenesis in ischemic myocardium after myocardial infarction and the mechanism may be associated withVEGF mRNA expression.
