摘 要 目的 探讨百合地黄汤加味(MBD/BDD)用于卒中后抑郁症(PSD)的潜在作用靶点及机制。方法 通过网络药理学方法
挖掘MBD/BDD治疗PSD的潜在靶点和关键途径。以局灶性脑缺血手术结合慢性不可预见的温和应激建立PSD模型大鼠,并随
机分为PSD模型组、MBD/BDD组(12.6 g/kg,以生药总量计)、盐酸氟西汀(FLX)组(阳性对照,2.3 mg/kg),另设空白对照组,每组
8只。各药物组大鼠灌胃相应药液,每天1次,连续21 d。通过旷场实验、强迫游泳实验评价MBD/BDD对模型大鼠抑郁样症状的
干预效果;剖取各组大鼠脑组织并提取总RNA,进行转录组测序和生物信息学分析,并基于上述结果对变化显著的基因和常见神
经营养因子进行mRNA和蛋白水平表达验证。结果 共获得MBD/BDD抗抑郁相关靶基因131个(如IL1B、AKT1等),涉及神经活
性配体-受体相互作用、环磷酸腺苷等信号通路。MBD/BDD可显著延长或增加PSD模型大鼠在中心方格花费的总时间及行进的
总距离,显著缩短累计不动时间(P<0.05)。经MBD/BDD干预后,大鼠脑组织中发生变化的基因远多于FLX组,且PSD模型组、
MBD/BDD组、FLX组的基因谱存在明显差异;MBD/BDD组与PSD模型组之间的差异表达基因(DEGs)共1 351个,其中178个显
著下调、1 173个显著上调(P<0.05);这1 351个DEGs涉及神经元分化、化学突触传递调节等,并在轴突引导、胆碱能突触和神经
活性配体-受体相互作用方面显著富集;MBD/BDD组大鼠脑组织中上调幅度排名前30位的基因均与神经元增殖、发育、分化和迁
移有关。经MBD/BDD干预后,大鼠脑组织中Fezf2、Arx、Ostn、Nrgn基因和脑源性神经营养因子、酪氨酸激酶受体B蛋白的相对
表达量均显著升高(P<0.05)。结论 MBD/BDD的抗PSD作用可能与上调神经元增殖、发育、分化和迁移相关基因的表达,促进
神经结构和功能的修复有关。

ABSTRACT OBJECTIVE To explore the potential targets and mechanisms of the modified Baihe dihuang decoction (MBD/
BDD) applied in post-stroke depression (PSD). METHODS Network pharmacology was used to mine the potential targets and key
pathways of MBD/BDD in the treatment of PSD. PSD model rats were induced by focal cerebral ischemia surgery combined with
chronic unforeseen mild stress, and then were randomly divided into PSD model group, MBD/BDD group (12.6 g/kg, by raw
drug), and fluoxetine hydrochloride (FLX) group (positive control, 2.3 mg/kg); a blank control group was also set up, with 8
rats in each group. Each administration group was given a corresponding medication solution by gavage once a day for 21
consecutive days. The intervention effect of MBD/BDD on depression-like symptoms in model rats was evaluated by open field and
forced swimming tests. The brain tissues of rats in each group were dissected and total RNA was extracted for transcriptome
sequencing and bioinformatics analysis. The mRNA and protein expressions of genes with significant changes and common
neurotrophic factors were verified based on the above results. RESULTS A total of 131 MBD/BDD antidepressant-related target
genes were obtained (such as IL1B and AKT1, etc.), which
