further divided into the model group, positive control group (Tretinoin cream, 0.045 g/kg), and QBCS low-, medium-, high-dose
          groups [3.55, 7.11, 14.22 g/kg (calculated by the amount of crude drug)], with 6 rats in each group. Rats in each drug group were
          treated with the corresponding drugs once daily for 14 consecutive days. After the final administration, changes in the appearance of
          the ears and histopathological changes in the ear tissues were observed, and serum levels of inflammatory factors, including tumor
          necrosis factor-α (TNF-α), interleukin-6 (IL-6) and IL-1β, were measured. Auricular tissues from the blank control group, model
          group  and  QBCS  medium-dose  group  were  collected  for  transcriptome  sequencing.  Differential  expressed  genes (DEGs)  were
          screened  and  subjected  to  Kyoto  Encyclopedia  of  Genes  and  Genomes  pathway  enrichment  analysis,  followed  by  validation  using
          real-time  quantitative  polymerase  chain  reaction  and  Western  blot  assay.  RESULTS  Compared  with  the  model  group,  rats  in  all
          QBCS  groups  showed  alleviated  auricular  acne  symptoms,  with  reduced  epidermal  thickening,  sebaceous  gland  hyperplasia,  and
          inflammatory cell infiltration. Serum levels of TNF-α (except for the QBCS low-dose group), IL-6 (except for the QBCS low-dose
          group)  and  IL-1β  were  significantly  decreased (P<0.05).  A  total  of  590  DEGs  were  identified (blank  control  group  vs.  model
          group), and 596 DEGs were identified (model group vs. QBCS medium-dose group). Above DEGs (blank control group vs. model
          group) were mainly enriched in Toll-like receptor (TLR) and nuclear factor-kappa B (NF-κB) signaling pathways, etc. Validation
          experiments  showed  that,  compared  with  model  group,  low-,  medium-  and  high-dose  of  QBCS  reduced,  to  varying  degrees,  the
          mRNA  expression  of TNF-α, TLR2,  interferon-γ  and  CXC  chemokine  ligand  8  in  the  auricular  tissues  of AV  rats,  increased  the
          mRNA  expression  of  peroxisome-proliferator-activated  receptor  gamma  and  tumor  protein  53,  and  inhibited  the  phosphorylation  of
          NF-κB  p65  protein  as  well  as  the  expressions  of  TLR2  and  myeloid  differentiation  primary  response  protein  88(MyD88) (P<
          0.05).  CONCLUSIONS  QBCS  can  alleviate  auricular  inflammation  and  skin  lesions  in  AV  rats.  This  effect  may  be  related  to
          inhibition  of  the  TLR/MyD88/NF-κB  signaling  pathway,  thereby  suppressing  the  expression  of  downstream  inflammatory  factors
          such as TNF-α.
