摘要: 目的 通过研究5-羟色胺受体1A (5-HTR1A)基因在经前期综合征(PMS)肝气郁证模型大鼠下丘脑区的表达,探讨该证的发病机制及药物作用靶点。方法 束缚法制备PMS肝气郁证模型大鼠,经前舒颗粒干预,获得正常组、造模组、给药组;运用RT-PCR和Western Blotting方法检测大鼠下丘脑区5-HTR1A mRNA及其蛋白表达; 应用软件SPSS 16.0,通过单因素方差分析及LSD法统计数据。结果 PMS肝气郁证模型组大鼠与正常组相比,下丘脑5-HTR1A mRNA及蛋白表达均显著降低; 经前舒颗粒给药后与造模组相比,表达均显著升高; 给药组与正常组相比,表达均无显著差异。结论 肝气郁证模型大鼠与正常大鼠相比,下丘脑5-HTR1A基因表达下降,通过经前舒颗粒干预后,恢复正常; 说明5-HTR1A基因可能与PMS肝气郁证相关,并且可以作为经前舒颗粒治疗该证的作用靶点。

Abstract: Objective To investigate the pathogenesis and drug target through the study about expression of 5-HTR1A in the hypothalamus of Pre-Menstrual Syndrome (PMS) Liver-qi Depression Model Rats. Methods The PMS Liver-qi Depression model was established by bounding the rat's feet, Then it was divided into control group, model group and treated group which were treated with Jingqianshu pellet. The mRNA and protein expressions of 5-HTR1A in the hypothalamus of the model Rats were detected by RT-PCR and Western Blotting separately. The data were analyzed by the one-way ANOVA and LSD with the software SPSS 16.0. Results The mRNA and protein expressions of 5-HTR1A in the hypothalamus of model group were decreased significantly compared with the control group. And the expressions of the treated group with Jingqianshu pellet were increased significantly compared with the model group. But there were no significant difference between the treated and the control groups. Conclusion The expressions of 5-HTR1A in the hypothalamus of PMS Liver-qi Depression Model Rats were decreased significantly compared with the control rats, and then the expressions level could recovered to the control level after treated with Jingqianshu pellet. Therefore, it was demonstrated that the expression of 5-HTR1A and PMS Liver-qi Depression may related, and the gene could be the drug target of Jingqianshu granule.
