摘要
目的:
本课题通过采用对高血压内皮功能疗效评价的指标进行严格的临床设计,通过测定具有祛痰化淤的加味温胆汤治疗高血压治疗前后ET-1,NO,vWF,FMD的变化,来论证加味温胆汤对改善高血压病患者临床症状,改善预后的意义,进而更加科学的评价其对高血压病的治疗效果,同时对于高血压的中药治疗客观评价有重要意义。
方法:
选择随机单盲对照的试验方案进行研究。纳入符合高血压诊断标准,属于痰湿阻络型的患者共60例,按照1:1的比例随机分组成治疗组和对照组,在给予基础治疗的基础上再分别给予加味温胆汤及安慰剂治疗,疗程为3周。在治疗前后观察眩晕、头痛等症状、血压水平、中医症候以及内皮指标的变化。
结果:
眩晕疗效:加味温胆组组眩晕积分有明显改善(P＜0.01),对照组治疗后积分虽有所下降但与治疗前比较无统计学差异(P＞0.05),治疗后加味温胆汤组改善程度明显优于对照组(P＜0.05)。眩晕临床疗效方面治疗组的总有效率为90%,明显优于对照组的66.67%,两组差异具有显著性差异(P＜0.01)。
血压水平疗效:治疗组和对照组血压水平均有下降(P＜0.001),尤以治疗组改善程度明显优于对照组(P＜0.005)。
中医症候:两组中医证候积分均有明显改善(P＜0.05),尤以治疗组改善程度明显优于对照组(P＜0.01)。中医症候临床疗效方面治疗组总有效率为90.0%,明显优于对照组的66.7%,两组差异具有显著性差异(P＜0.01)。
ET、NO变化:对照组治疗后虽然ET比治疗前略有下降,NO略有升高,但变化无显著性差异(P＞0.05),治疗组用加味温胆汤后ET比治疗前下降,NO比治疗前升高,两者均由显著性差异(P＜0.01)。治疗后加味温胆汤组的ET水平显著低于对照组(P＜0.01),治疗后加味温胆汤组的NO水平较对照组有明显升高(P＜0.05)。
vWF变化:治疗前两组vWF水平无显著性差异,治疗组用加味温胆汤后vWF水平比治疗前明显下降(P＜0.05),治疗后加味温胆汤组vWF水平明显低于对照组(P＜0.05),而对照组治疗后虽然vWF比治疗前略有下降,但无统计学差异(P＞0.05)。
FMD变化:两组无论从同组治疗前后或者是组间治疗前后比较均无显著性差异(P＞0.05)。
结论:
加味温胆汤能有效改善高血压患者眩晕疗效;加味温胆汤既能有效减少眩晕发作,又能改善中医证候群,无明显毒副作用;温胆汤是通过下调ET水平,同时上调NO水平,抑制vwF释放的作用从而使受损的血管内皮功能得以部分恢复。
Objective:To validate clinicalcurative effect that Jiawei Wendan Decoction improve clinical symptom and prognosis in patients of hypertension through testing the level of ET-1,NO,vWF in serum and FMD.
Method:This is a single-blind,randomized,matched controlled trial.60 patients that were diagnosed as hypertension and tanshi zuluo symdrome were randomly grouped to treatment group and controlled group.Each group had 30 cases.The two groups were treated with JiaWei WenDan Decoction and placebo separately on the basis of basical treatment by 3 weeks continuously.After 3 weeks,we observed the change of ET-1,NO,vWF,FMD,Blood pressure reading, clinical symptoms of hypertension,and Chinese medical symptoms.
Result:Clinical symptoms of hypertension curative effect:Symptoms of vertigo were improved effectively in treatment group,while there was no statistical significance in controlled group.Treatment group shown 90%and controlled group shown 66.7%.Their differences had great statistical significance.
Blood pressure effect:The Blood pressure effect of the two group separately shown 86.7%and 56.7%.Their differences had great statistical significance. Chinese medical symptoms curative effect:Chinese medical symptoms were improved effectively in two groups,but the treatment group was more improved than controlled group.Treatment group shown 90%and controlled group shown 66.7%.Their differences had great statistical significance.
ET,NO:Although the level of ET in serum decreased and the level of NO increased in controlled group,there were no statistical significance.The level of ET decreased,the level of NO increased after treatment in treatment group which had great statistical significance.The level of ET in serum was much lower than that of controlled group after treatment.The level of NO in serum was much higher than that of controlled group after treatment.
vWF:The level of vWF of treatment group was lower than controlled group which had statistic significance.Furthermore,the level of vWF was much lower than that of controlled group after treatment.Although the level of vWF of controlled group decreased but there was no statistical significance.
FMD:There was no change of FMD in two groups after treatment.There was no change of FMD after treatment in the same group.
Conclusion:The results of the experiment show that Jiawei Wendan Decoction can effectively improve blood pressure effect.It can control vertigo attack, improve Chinese medical symptoms without side-effect.By decreasing the level of ET and increasing the level of NO in serum and controlling reversed blood endothelium function obstacle partly.
