          摘   要  目的  探讨芍药苷抗高泌乳素血症(HPRL)的作用机制。方法  将24只雌性SD大鼠分为空白对照组(灌胃5%阿拉伯胶
          溶液)、奥氮平组(模型组,灌胃 5 mg/kg 奥氮平混悬液)、芍药苷组(灌胃 5 mg/kg 奥氮平混悬液,2 h 后再灌胃 50 mg/kg 芍药苷溶
          液),每组8只。每天1次,连续造模/给药至奥氮平组血浆泌乳素(PRL)水平高于空白对照组2倍。末次给药后,检测各组大鼠的
          血浆PRL水平,分析其肠道菌群变化[包括α多样性(Simpson、Chao1、Shannon指数)、β多样性和物种组成(门/属水平)分析、微生
          物组学LEfSe分析];进行粪便非靶向代谢组学技术分析(包括多元统计分析、差异代谢物筛选及通路富集分析);采用Spearman相
          关分析探究差异菌群与粪便差异代谢物的相关性。结果  与奥氮平组比较,芍药苷组大鼠血浆 PRL 水平显著降低(P<0.05)。
          16S rRNA高通量测序结果显示,芍药苷可显著改善HPRL大鼠肠道菌群的α多样性和β多样(P<0.05),使其趋向于空白对照组。
          在门水平上,芍药苷可显著降低HPRL大鼠厚壁菌门、脱硫菌门的相对丰度,显著升高疣微菌门的相对丰度(P<0.05);在属水平
          上,芍药苷可显著逆转HPRL大鼠脱硫弧菌属、异杆菌属、普雷沃氏菌属NK3B31组等相对丰度的变化(P<0.05)。LEfSe分析结
          果显示,芍药苷可显著富集放线菌门、葡萄球菌目、棒状杆菌目等菌群(P<0.05)。共筛选出51个差异代谢物,代谢产物显著聚集
          于类固醇激素生物合成、前列腺癌、卵巢类固醇生成等代谢通路。相关性分析显示,肠道差异菌属如脱硫弧菌属、气球菌属等的相
          对丰度与四氢皮质醇、肾上腺甾酮等类固醇激素代谢物含量显著相关(P<0.05)。结论  芍药苷可能通过调节HPRL大鼠肠道菌
          群结构(包括显著降低脱硫弧菌属、异杆菌属、气球菌属的相对丰度,显著上调瘤胃球菌科UBA1819组、鼠肠杆菌属的相对丰度)、
          调控类固醇激素生物合成代谢通路来降低PRL水平,从而发挥抗HPRL的作用。

          ABSTRACT    OBJECTIVE To investigate the mechanisms of paeoniflorin (PF) in anti-hyperprolactinemia (HPRL). METHODS
          Twenty-four  female  SD  rats  were  divided  into  blank  control  group (intragastric  administration  of  5%  gum  arabic  solution),
          olanzapine  group (model  group,  intragastric  administration  of  5  mg/kg  olanzapine  suspension),  and  PF  group (intragastric
          administration of 5 mg/kg olanzapine suspension, followed by gavaging with 50 mg/kg PF solution 2 hours later) with 8 rats in each
          group.  Once  a  day,  continuously  model/administer  until  the  plasma  prolactin (PRL)  levels  in  the  olanzapine  group  were  twice  as
          high as those in the blank control group. PRL levels were measured. The changes in gut microbiota of rats were analyzed, including
          assessments of α-diversity (Simpson, Chao1, and Shannon indexes), β-diversity, species composition analysis (at the phylum and
          genus  levels),  and  microbiome  LEfSe  analysis.  Fecal  untargeted  metabolomics  technology  was  employed  to  analyze  the  effects  of
          PF on the fecal metabolomics of rats, including multivariate statistical analysis, screening of differential metabolites, and pathway
          enrichment  analysis.  Spearman  correlation  analysis  was  performed  to  examine  the  correlations  between  differential  microbiota  and
          differential  fecal  metabolites.  RESULTS  PF  significantly  reduced  serum  PRL  levels  of  rats  in  olanzapine  group (P<0.05).  16S
          rRNA  sequencing  revealed  that  PF  improved  the  α-diversity  and  β-diversity  of  gut  microbiota  in  HPRL  rats (P<0.05),  restoring
          them to levels similar to the blank control group. At the phylum level, PF significantly reduced the relative abundance of Firmicutes
                                                              and  Desulfobacterota,  while  increasing  the  relative  abundance
