Abstract:
ObjectiveTo establish a traditional Chinese medicine （TCM） syndrome model with yin deficiency and internal heat， discuss the rationality of model evaluation， and analyze differentially expressed genes in multiple dimensions to explore the molecular mechanism-signaling pathways as well as key targets of Baihe Dihuangtang （BHDH） in treating depression with Yin deficiency and internal heat. MethodForty male SD rats were randomly divided into a blank control group，a model group，a fluoxetine group （positive drug），a BHDH group， and a Zhibai Dihuangtang group （positive drug for Yin deficiency and internal heat）. The depression model with Yin deficiency and internal heat was induced by chronic unpredictable mild stress （CUMS）combined with Chinese herbal drugs with warm and heat nature. The model established was comprehensively evaluated by the detection of the basic condition， behavioral performance， and biochemical indicators of rats in each group. The differentially expressed genes were screened out by mRNA sequencing and underwent Gene Ontology（GO） and Kyoto Encyclopedia of Genes and Genomes（KEGG） pathway enrichment analyses. The protein-protein interaction （PPI） network was plotted and key genes were analyzed to explore the underlying mechanism of BHDH in treating depression with Yin deficiency and internal heat. ResultThe comparison of basic conditions， behavioral assays， energy metabolism， endocrine hormones， cytokines， and neurotransmitters showed that the model was properly induced. BHDH could significantly improve depression with Yin deficiency and internal heat by regulating the pathways related to the nervous system， endocrine system， and inflammatory and immune system. The key genes of the PPI network were Fos， Epha8， Npy2r， Htr2c， and Nr4a1. ConclusionUnder the guidance of TCM theories of treatment based on syndrome differentiation and etiology and pathogenesis，this study established a depression model with yin deficiency and internal heat in animals and evaluation system in accordance with the symptoms and signs of emotional diseases， and further confirmed the scientificity of the modeling method and the underlying mechanism of BHDH in interfering with depression with Yin deficiency and internal heat based on the results of mRNA sequencing.
