          摘  要  目的  基于网络药理学方法探讨地榆皂苷Ⅰ对脓毒症大鼠急性肺损伤的保护作用及机制,并通过实验进行验证。方法
          使用网络药理学方法预测地榆皂苷Ⅰ治疗脓毒症急性肺损伤的潜在靶点。采用盲肠结扎穿孔术复制大鼠脓毒症模型进行实验验
          证。将 192 只 SD 大鼠按随机数字表法分为假手术组(Sham 组)、脓毒症组(Sep 组)、常规治疗组(CT 组)和地榆皂苷Ⅰ治疗
          组(ZgⅠ组)。Sham组、Sep组给予无菌生理盐水,CT组和ZgⅠ组大鼠给予相应剂量的林格氏液和地榆皂苷Ⅰ。观察各组大鼠动
          脉血气、血清炎症因子、肺湿/干质量比、肺组织病理变化、肺血管通透性、肺静脉紧密连接蛋白1(ZO-1)和血管内皮钙黏蛋白(VE-
          cadherin)蛋白表达、72 h存活情况。结果 网络药理学结果显示,地榆皂苷Ⅰ治疗脓毒症的潜在靶点有47个,基因本体功能富集分
          析和京都基因与基因组百科全书通路富集分析结果显示,其机制可能与活性氧族代谢正向调控 (positive regulation of reactive
          oxygen species metabolic process)、损伤修复(would healing)、内皮细胞增殖调控(regulation to endothelial cell proliferation)、细胞激
          活(cell activation)、血管发生(blood vessel development)、氧化应激反应(response to oxidative stress)等生物学过程和细胞凋亡
         (apoptosis)、紧密连接(tight junction)、缺氧诱导因子1信号通路(HIF-1α signaling pathway)等信号通路有关。实验验证结果显示,
          与Sham组比较,Sep组大鼠动脉氢离子浓度指数、动脉血氧分压水平显著降低(P<0.05),二氧化碳分压水平、血清肿瘤坏死因子
          α、白细胞介素 6 水平显著升高(P<0.05);肺湿/干质量比显著升高(P<0.05);肺静脉 ZO-1、VE-cadherin 蛋白表达水平显著降低
         (P<0.05);72 h存活率明显降低,存活时间显著缩短(P<0.05);肺组织病理观察结果显示,大鼠肺泡出现大范围破裂,肺泡壁增厚
          并伴有水肿,有明显炎性细胞浸润;肺血管通透性观察结果显示,大鼠肺表面颜色暗淡,有大量伊文思蓝渗出,左下肺呈明显深蓝
          色。与Sep组比较,CT组和ZgⅠ组以上指标水平大部分显著逆转(P<0.05),肺组织病理和肺血管通透性均明显改善,其中ZgⅠ
          组恢复程度大于CT组,接近Sham组结果。结论 地榆皂苷Ⅰ可显著减轻脓毒症大鼠炎症反应及急性肺损伤,其机制与血管功能
          和紧密连接信号通路有关。

          ABSTRACT   OBJECTIVE To investigate the protective effects and mechanism of ziyuglycoside Ⅰ on acute lung injury in sepsis
          rats  based  on  network  pharmacology,  and  conduct  experimental  verification.  METHODS  The  network  pharmacology  was  used  to
          predict  the  potential  target  of  ziyuglycoside  Ⅰ  in  the  treatment  of  acute  lung  injury  following  sepsis. The  rat  model  of  sepsis  was
          reproduced by cecum ligation and puncture for experimental verification. Totally 192 SD rats were randomly divided into the sham
          operation group (Sham group), sepsis group (Sep group), conventional therapy group (CT group) and ziyuglycoside Ⅰ group (Zg
          Ⅰ  group),  respectively.  Sham  group  and  Sep  group  were  given  sterile  normal  saline,  and  CT  group  and  ZgⅠ  group  were  given
          relevant volume of Ringer’s solution and ziyuglycoside Ⅰ. The arterial blood gas, serum inflammatory factors, lung wet/dry mass
          ratio,  pathological  changes  of  lung  tissue,  pulmonary  vascular  permeability,  the  expressions  of  pulmonary  vein  tight  junction
          protein  1 (ZO-1)  and  vascular  endothelial  cadherin (VE-cadherin)  protein  and  72-hour  survival  were  observed  in  each  group.
          RESULTS  Results  of  network  pharmacology  showed  that  there  were  47  potential  targets  of  ziyuglycoside  Ⅰ  in  the  treatment  of
                                                             sepsis.  The  results  of  gene  ontology  function  enrichment
