          摘   要  目的  研究铁皮石斛对干皮症小鼠皮肤损伤的改善作用及机制。方法  将小鼠随机分为对照组、模型组、铁皮石斛组,每
          组5只。除对照组(仅做剃毛处理)外,其余各组小鼠采用丙酮-乙醚混合液复制干皮症模型,连续造模5 d。铁皮石斛组小鼠于每
          天第 1 次造模后 2 h 时,涂抹 200 μL 铁皮石斛混悬液(0.2 mg/mL),对照组和模型组小鼠涂抹等体积纯水,每天 1 次,直至造模结
          束。末次给药后,观察小鼠皮肤损伤情况和病理学形态;采用免疫荧光法检测小鼠皮肤组织中聚丝蛋白(Filaggrin)、兜甲蛋白(Lo‐
          ricrin)、增殖细胞核抗原Ki67蛋白表达水平;采用16S rRNA测序法联合基因本体和京都基因与基因组百科全书(KEGG)富集分
          析筛选铁皮石斛对干皮症皮肤损伤改善作用的核心通路,并进行验证。结果  与对照组比较,模型组小鼠有明显的搔抓行为,皮肤
          有大量鳞屑,表皮角化过度、棘层肥厚;皮肤鳞屑评分、表皮厚度和皮肤组织中Ki67、Filaggrin、Loricrin蛋白表达水平均显著增加/
          升高(P<0.05);与模型组比较,铁皮石斛组小鼠搔抓行为和鳞屑减少,皮肤角化程度减轻,上述定量指标显著减小/降低(P<
          0.05)。核心通路筛选结果显示,差异基因涉及的KEGG通路包括白细胞介素17(IL-17)、肿瘤坏死因子(TNF)等信号通路;进一步
          验证实验发现,经铁皮石斛干预后,小鼠皮肤组织中IL-17、TNF信号通路下游效应分子CCN1、Hbegf、Tnfrsf12a、Thbs1的mRNA
          表达水平均显著降低(P<0.05)。结论  铁皮石斛可修复干皮症小鼠皮肤损伤;其作用机制与恢复角质形成细胞的增殖与分化平
          衡,下调CCN1、Hbegf、Tnfrsf12a、Thbs1 mRNA表达有关。

          ABSTRACT    OBJECTIVE  To  study  the  improvement  effect  and  mechanism  of  Dendrobium  officinale  on  skin  damage  in  mice
          with  xeroderma.  METHODS  The  mice  were  randomly  divided  into  control  group,  model  group,  and  D.  officinale  group,  with  5
          mice  in  each  group.  Except  for  the  control  group (which  only  underwent  shaving  treatment),  the  mice  in  all  other  groups  were
          induced  to  develop  a  xeroderma  model  using  an  acetone-ether  mixture  for  five  consecutive  days.  The  mice  in  D.  officinale  group
          were treated with 200 μL of D. officinale suspension (0.2 mg/mL) two hours after the first modeling each day. Mice in the control
          group  and  the  model  group  were  applied  with  an  equal  volume  of  pure  water;  once  a  day,  until  the  end  of  the  modeling  process.
                                                              After  last  medication,  skin  lesions  and  pathological
