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.
