Abstract:
Objective Screening of modified Foshou San to improve cerebral ischemia,determine the best prescription composition and the proper dose.Methods Using data mining method,the traditional Chinese medicine for hypertensive intracerebral hemorrhage(HICH)were screened,and cluster analysis was carried out to obtain Jiawei Foshou San combinations;According to the mixed uniform design U14(42×33×22),the auricular artery dilatation experiment and acute cerebral ischemia induced by saturated magnesium chloride in mice were used to observe the auricular artery dilatation index and survival time of mice,and the pharmacological effects of each prescription to improve cerebral ischemia were evaluated.On the basis of visual analysis of pharmacodynamics,stepwise multiple regression analysis was carried out,and the regression equation was used to calculate the best prescription composition and dose of Jiawei Foshou San.The optimized prescription was verified by acute cerebral ischemia experiment in mice.Results A total of 51 prescriptions that may be used for the treatment of HICH were selected by data mining,including 103 Chinese herbs,with a total frequency of 535 times.The results of mixed uniform design U14(42×33×22)test showed that the auricular artery index of mice in each prescription group of Jiawei Foshou San increased to varying degrees.The differences between prescription 4,8,12 and 13 were significant(P<0.05),and the differences between prescription 3,7,9,11 and 14 were extremely significant(P<0.01).The survival time of acute cerebral ischemia in mice was prolonged to varying degrees in each group of Jiawei Foshou San,and the difference between prescription 2-14 groups and the blank group was statistically significant(P<0.01).The prescription of the new Jiawei Foshou San was determined as 60 g of Astragalus membranaceus,60 g of Angelica sinensis,24 g of Ligusticum chuanxiong,15 g of Paeonia lactiflora and 9 g of Dilong from the intuitive analysis.The validation results showed that the high and middle dosage of the new Jiawei Foshou San could significantly prolong the breathing time,increase the number of breaths,and prolong the time of normal pressure hypoxia tolerance in mice with acute cerebral ischemia(P<0.01,P<0.05).Conclusion Using mixed uniform design combined with improving cerebral ischemia effect index can determine the best prescription composition and the best dose of Jiawei Foshou San,and the effect of improving cerebral ischemia is certain.
