          摘  要  目的  从肠道菌群与代谢组学的角度探究仙方活命饮加减方防治脓毒症致肝损伤的作用机制。方法  采用体质量均衡分
          配法将60只SD大鼠分为空白组(生理盐水)、模型组(生理盐水)、阳性对照药组(地塞米松片,5.0 mg/kg)和仙方活命饮加减方高、
          中、低剂量组(以生药计分别为6.0、3.0、1.5 g/kg),每组10只。灌胃相应药物/生理盐水,灌胃体积均为10 mL/kg;每天给药1次,连
          续14 d。末次给药后,除空白组外,其余各组大鼠均腹腔注射脂多糖 10 mg/kg建立脓毒症模型。造模12 h后,检测大鼠血清中炎
          症指标[白细胞介素 1β(IL-1β)、IL-6、肿瘤坏死因子 α(TNF-α)]和肝功能指标[总胆固醇(TC)、甘油三酯(TG)、天冬氨酸转氨酶
         (AST)、丙氨酸转氨酶(ALT)]水平;采用16S rRNA技术联合肝脏代谢组学分析大鼠肠道菌群及肝脏代谢产物的变化。结果  仙方
          活命饮加减方可显著改善脓毒症致肝损伤大鼠血清中炎症指标与肝功能指标(P<0.05或P<0.01),对5种优势菌门中11种菌属
         (如阿克曼氏菌属、乳杆菌属、沃氏嗜胆菌属等)的相对丰度有显著回调作用(P<0.05或P<0.01)。共鉴定出甘氨胆酸、磷脂酰胆
          碱、牛磺酸等12个与该方改善脓毒症致肝损伤相关的潜在生物标志物(P<0.05或P<0.01),主要涉及甘油磷脂代谢、嘌呤代谢和
          初级胆汁酸代谢等代谢通路。结论  仙方活命饮加减方可通过调节肠道菌群和肝脏代谢,改善脓毒症致肝损伤。

          ABSTRACT   OBJECTIVE  To  explore  the  mechanism  of  modified  Xianfang  huoming  decoction  in  the  treatment  of  sepsis-
          induced  liver  injury  from  the  perspective  of  gut  microbiota  and  metabolites.  METHODS  Sixty  SD  rats  were  divided  into  blank
          group (normal  saline),  model  group (normal  saline),  positive  control  drug  group (Dexamethasone  tablet,  5.0  mg/kg),  modified
          Xianfang huoming decoction high-dose, middle-dose and low-dose groups (6.0, 3.0, 1.5 g/kg, calculated by crude drug) according
          to  equilibrium-partitioning  approach  of  body  mass,  with  10  rats  in  each  group.  They  were  given  relevant  drug/normal  saline  10  mL/
          kg, once a day, for consecutive 14 days. After the last medication, except for blank group, other groups were given intraperitoneal
          injection  of  lipopolysaccharide  10  mg/kg  to  induce  sepsis  model.  Twelve  hours  after  modeling,  serum  levels  of  inflammatory
          indexes  in  rats  [interleukin-1β (IL-1β),  IL-6,  tumor  necrosis  factor-α (TNF-α)]  and  liver  function  indicators  [total  cholesterol
         (TC),  triglyceride (TG),  aspartate  transaminase (AST),  alanine  transaminase (ALT)]  were  detected.  The  changes  of  gut
          microbiota  and  liver  metabolites  in  rats  were  analyzed  by  16S  rRNA  technology  and  liver  metabolomics.  RESULTS  Modified
          Xianfang huoming decoction could significantly improve the indexes of serum inflammatory indexes and liver function in rats with
          sepsis-induced liver injury (P<0.05 or P<0.01); there was a significant callback effect on the relative abundance of 11 genera of
          bacteria (such  as  Akkermansia,  Lactobacillus  and  Bilophila)  among  the  5  dominant  phyla(P<0.05  or  P<0.01).  Twelve
                                                             metabolites  related  to  liver  injury  caused  by  sepsis  were
