          摘  要  目的  基于血清外泌体微RNA(miRNA),研究连翘-金银花药对对急性肺损伤(ALI)的改善作用及机制。方法  将大鼠分
          为空白组(生理盐水)、模型组(生理盐水)、连翘-金银花药对组(2.55 g/kg),每组10只。除空白组外,其余各组大鼠均通过气管滴
          注5 mg/mL脂多糖复制ALI模型。造模后,各组大鼠灌胃相应药液/生理盐水,每天1次,连续3 d。末次给药后,观察大鼠肺组织
          病理学形态;测定肺组织湿干重比和支气管肺泡灌洗液(BALF)中白细胞数量;检测BALF中炎症因子[肿瘤坏死因子α(TNF-α)、
          白细胞介素1β(IL-1β)、IL-10]水平;提取大鼠血清外泌体,利用高通量测序技术筛选外泌体中差异表达miRNA,并进行京都基因
          与基因组百科全书(KEGG)富集分析。基于筛选的差异表达 miRNA 和富集的 KEGG 通路,通过体外细胞实验进行机制验证。
          结果  动物实验结果显示,经连翘-金银花药对干预后,ALI大鼠湿干重比以及BALF中白细胞数量和TNF-α、IL-1β水平均显著降
          低/减少(P<0.01),IL-10 水平显著升高(P<0.01)。高通量测序实验结果显示,连翘-金银花药对可显著上调外泌体中 miR-345-
          3p、miR-194-5p、miR-653-5p 等的表达,其中差异表达 miRNA 的靶基因涉及的 KEGG 通路包括缺氧诱导因子 1(HIF-1)信号通路
          等。细胞验证实验结果显示,过表达的miR-345-3p可显著升高细胞上清液中IL-10水平(P<0.01),显著降低细胞上清液中TNF-
          α、IL-1β水平以及细胞中蛋白激酶B1、磷脂酰肌醇3-激酶、HIF-1α的mRNA及其蛋白表达水平(P<0.01)。结论  连翘-金银花药
          对可通过上调血清外泌体中miR-345-3p表达,抑制HIF-1信号通路活性,从而减轻炎症反应,进而发挥改善ALI的作用。

          ABSTRACT     OBJECTIVE  To  study  the  ameliorative  effect  and  mechanism  of  Forsythia  suspensa-Lonicera  japonica  herb  pair
          on  acute  lung  injury (ALI)  based  on  serum  exosomal  microRNA (miRNA).  METHODS  The  rats  were  randomly  divided  into  a
          blank group (normal saline), model group (nomal saline), and F. suspensa-L. japonica herb pair group (2.55 g/kg), with 10 rats
          in each group. Except for the blank group, the other groups were used to establish an ALI model by intratracheal dripping of 5 mg/
          mL  lipopolysaccharides. After  modeling,  each  group  was  given  relevant  medicine/normal  saline  intragastrically,  once  a  day,  for  3
          consecutive  days. After  the  last  medication,  the  pathological  status  of  lung  tissue  was  observed;  lung  wet-to-dry  weight  ratio  and
          leukocyte  counts  in  bronchoalveolar  lavage  fluid (BALF)  were  determined.  The  levels  of  inflammatory  factors  [tumor  necrosis
          factor-α(TNF-α),  interleukin-1β (IL-1β),  IL-10]  in  BALF  were  determined.  Exosomes  were  isolated  from  rat  serum,  and  high-
          throughput sequencing technology was employed to screen differentially expressed miRNA within the exosomes, followed by Kyoto
          Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Based on the screened differentially expressed miRNA and the
          enriched KEGG pathways, in vitro cellular experiments were conducted for validation. RESULTS  The animal experimental results
          demonstrated  that  after  intervention  with  the  F.  suspensa-L.  japonica  herb  pair,  the  wet-to-dry  weight  ratio,  the  number  of
          leukocytes  in  BALF,  as  well  as  the  levels  of  TNF-α  and  IL-1β  in  BALF  of ALI  rats  were  all  significantly  reduced (P<0.01),
          while the level of IL-10 was significantly increased (P<0.01). The results of high-throughput sequencing experiments revealed that
                                                             the  F.  suspensa-L.  japonica  herb  pair  could  significantly  up-
