          摘   要  目的  研究秫米提取物对失眠小鼠的改善作用及可能机制。方法  将小鼠按随机数字表法分为空白组、模型组、阳性对照
          组(地西泮,2.6 mg/kg)和秫米提取物低、中、高剂量组(1.2、2.4、4.8 g/kg),每组10只。除空白组外,其余各组小鼠均腹腔注射对氯
          苯丙氨酸(PCPA)建立失眠模型。造模成功后,空白组和模型组小鼠灌胃等体积生理盐水,各给药组小鼠灌胃相应药物,灌胃体积
          为0.01 mL/g,每天1次,连续7 d。给药结束后,进行旷场实验观察小鼠行为学变化,测定小鼠海马组织中5-羟色胺(5-HT)、5-羟吲
          哚乙酸(5-HTAA)以及血清中5-HT、脑源性神经营养因子(BDNF)、白细胞介素2(IL-2)、IL-6、B细胞淋巴瘤2(Bcl-2)、Bcl-2相关X
          蛋白(Bax)含量;测定小鼠海马中磷脂酰肌醇 3 激酶/蛋白激酶 B/核因子 κB(PI3K/Akt/NF-κB)信号通路相关蛋白的表达水平。
          结果  与模型组比较,秫米提取物高剂量组小鼠的总运动时间均显著延长、总静止时间均显著缩短(P<0.01),站立次数及修饰次
          数均显著减少(P<0.01);血清中5-HT、BDNF、Bcl-2的含量和Bcl-2/Bax比值均显著升高,IL-2、IL-6、Bax的含量均显著降低(P<
          0.05或P<0.01);海马组织中5-HTAA的含量及PI3K、Akt蛋白磷酸化水平均显著升高,NF-κB p65蛋白磷酸化水平显著降低(P<
          0.05)。结论  高剂量秫米提取物对失眠小鼠有较好的改善效果,其作用机制可能与调控PI3K/Akt/NF-κB信号通路有关。

          ABSTRACT    OBJECTIVE To investigate the effects of Setaria italica extract on improving insomnia model mice and to explore
          its  potential  mechanisms.  METHODS  The  mice  were  randomly  assigned  into  blank  group,  model  group,  positive  control  group
         (diazepam, 2.6 mg/kg), and S. italica extract low-dose, medium-dose and high-dose groups (1.2, 2.4, 4.8 g/kg), with 10 mice in
          each  group.  Except  for  the  blank  group,  all  other  groups  received  intraperitoneal  injection  of  para-chlorophenylalanine (PCPA)  to
          establish  the  insomnia  model.  After  modeling,  the  blank  group  and  model  group  were  given  a  constant  volume  of  normal  saline
          intragastrically, and administration groups were given relevant medicine intragastrically, with a volume of 0.01 mL/g, once a day,
          for  7  consecutive  days. After  the  administration,  the  open-field  test  was  conducted  to  observe  the  praxiological  changes  of  mice,
          and  to  determine  the  levels  of  5-hydroxytryptamine (5-HT)  and  5-hydroxyindoleacetic  acid (5-HTAA)  in  the  hippocampal  tissue,
          as well as the contents of 5-HT, brain-derived neurotrophic factor (BDNF), interleukin-2 (IL-2), IL-6, B-cell lymphoma-2 (Bcl-
          2), and Bcl-2-associated X protein (Bax) in the serum. The expression of phosphoinositide 3-kinase/protein kinase B/nuclear factor-
          κB (PI3K/Akt/NF-κB)  signaling  pathway  related  protein  was  determined  in  the  hippocampus  of  mice.  RESULTS  Compared  with
          the model group, the total exercise time of mice in S. italica extract high-dose group was significantly prolonged, but the total rest
          time was significantly shortened (P<0.01); the number of standing times and modification times were significantly reduced (P<
          0.01). The contents of 5-HT, BDNF, and Bcl-2 in serum, and Bcl-2/Bax were significantly increased, while the contents of IL-2,
                                                              IL-6,  and  Bax  were  significantly  reduced (P<0.05  or  P<
