基于均匀设计的开心解郁方抗抑郁主效应中药筛选研究

摘要

目的：筛选开心解郁方中抗抑郁的主效应中药。方法采用 U11(1110)均匀设计表和使用表,将开心解郁方(人参、巴戟天、赤芍、远志、柴胡、枳实)设成11个剂量配伍组,加上阳性药组(地西泮)和阴性对照组,共13组,实验小鼠按体质量随机分组。连续给药14 d 后分别进行悬尾实验、强迫游泳实验和自主活动实验。结果以悬尾测试的不动时间百分比(Y1)为因变量,以 X1～X6为自变量,拟合多元非线性回归分析,Y1＝1.1331－0.8423×X1＋0.4382×X3－0.7129×X6,提示人参、枳实具有明显抗抑郁作用；赤芍具有促进抑郁的作用。以强迫游泳的不动时间(Y2)为因变量,以 X1～X6为自变量拟合多元非线性回归分析,Y2＝167.69－2.99×X12－2.14×X1－1.65×X6,提示人参、枳实具有明显的抗抑郁作用。小鼠自主活动测试显示,X1～X6对小鼠自主活动指数(Y3)无显著影响,提示开心解郁方的抗抑郁作用与中枢兴奋性无关。结论人参和枳实是开心解郁方中抗抑郁的主效应中药。%Objective To pick up the Chinese materia medica with principal antidepressive effect in Kaixin Jieyu prescription based on uniform distribution. Methods 11 groups of concerted application with different dosages of six simplex Chinese materia medica (X 1-X 6) of Kaixin Jieyu prescription were arranged by the designlist and sustentacular table of U11(1110). Positive and negative control groups were also formed. Mice were randomized into 13 groups according to body weight and fed with medicine 14 d and estimated by tail suspension test, forced swim test and autonomic activities test. Results Relationship of percentage of immovability time (Y 1) in the tail suspension test and X 1-X 6 were analyzed with multivariant non-linear regression analysis and resulted in Y 1=1.133 1-0.842 3×X 1+0.438 2×X 3-0.712 9×X 6. It indicated that both Radix Ginseng and Fructus Aurantii Immaturus had obvious antidepressive function, and Radix Paeoniae Rubra may facilitate depression. Relationship of immovability time (Y 2) in forced swim test and X1-X6 were analyzed with multivariant non-linear regression analysis and resulted in Y 2=167.69-2.99×X 12-2.14×X 1-1.65×X 6. It also indicated that both Radix Ginseng and Fructus Aurantii Immaturus had obvious antidepressive function. Relationship of autonomic activities index (Y 3) in autonomic activities test indicated that X 1-X 6 had no obvious influence on Y 3 and antidepressive function of KaixinJieyu prescription was not concerned with excitability to the central nervous system. Conclusion Radix Ginseng and Fructus Aurantii Immaturus were the Chinese materia medica with principal antidepressive effect in Kaixin Jieyu prescription.
