          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
