As a traditional Chinese herbal medicine, Cornu Cervi Degelatinatum (CCD) has the effect of warming the kidney to support yang, astringing, and stopping bleeding, and is used for spleen kidney yang deficient (SKYD). This experiment was to investigate the therapeutic effects of different processes of CCD on SKYD type ulcerative colitis (UC) rats and to explore its impact on the intestinal flora of rats. Methods: ELISA was used to study the anti-inflammatory activity of Cornu Cervi Degelatinatum processed with water (WCCD) and Cornu Cervi Degelatinatum processed with vinegar (VCCD). 16SrRNA and transcriptome sequencing were used to detect the composition of rat intestinal flora and gene expression; RT-PCR and Western blot were used to verify the role of WCCD and VCCD in treating UC. Results: WCCD and VCCD have therapeutic effects on UC, could reduce tissue damage. VCCD performed better in improving Bacteroidetes/Firmicutes ratios and species evenness and abundance; performed better in increasing the quantity of lactobacillus. VCCD simultaneously inhibit the intestinal inflammatory response through NCK2, PAK4, and JNK signaling pathways. Conclusions: WCCD and VCCD play a therapeutic role in UC by regulating the proportion of different flora in the intestinal flora. VCCD regulates the intestinal flora and inflammatory response by interfering with the NCK2, PAK4 and JNK signaling pathways.
Due to the limited supply of autologous bone grafts, there is a need to develop more bone matrix materials to repair bone defects. Xenograft bone is expected to be used for clinical treatment due to its exact structural similarity to natural bone and its high biocompatibility. In this study, decellularized antler cancellous bone matrix (DACB) was first prepared, and then the extent of decellularization of DACB was verified by histological staining, which demonstrated that it retained the extracellular matrix (ECM). The bioactivity of DACB was assessed using C3H10T1/2 cells, revealing that DACB enhanced cell proliferation and facilitated cell adhesion and osteogenic differentiation. When evaluated by implanting DACB into nude mice, there were no signs of necrosis or inflammation in the epidermal tissues. The bone repair effect of DACB was verified in vivo using sika deer during the antler growth period as an animal model, and the molecular mechanisms of bone repair were further evaluated by transcriptomic analysis of the regenerated tissues. Our findings suggest that the low immunogenicity of DACB enhances the production of bone extracellular matrix components, leading to effective osseointegration between bone and DACB. This study provides a new reference for solving bone defects.
Depression is one of the most common neurological diseases, which imposes a substantial social and economic burden on modern society. The purpose of this study was to explore the mechanism of total ginsenoside ginseng root (TGGR) in the treatment of depression through a comprehensive strategy combining network pharmacology, transcriptomics, and in vivo experimental validation. The Traditional Chinese Medicine Systematic Pharmacology (TCMSP) database and literature were used to collect the main components and targets of TGGR. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were applied to explore the underlying mechanisms. In addition, the chronic unpredictable mild stress (CUMS)-induced C57BL/6 mouse model was used to evaluate the antidepressant activity of TGGR. The results showed that TGGR improved depression-like behavior in mice and increased the decrease in serum 5-hydroxytryptamine (5-HT) and brain-derived neurotrophic factor (BDNF) levels caused by CUMS. Combined network pharmacology and transcriptomic analysis showed that the AMP-activated kinase (AMPK) signaling pathway mainly enriched the core target. Immunohistochemistry, Western blotting, and reverse transcription quantitative polymerase chain reaction (RT-qPCR) were used to confirm whether TGGR exerts antidepressant effects by regulating this pathway. The results showed that TGGR has a regulatory impact on related proteins in the AMPK pathway, and the regulatory effect of TGGR on proteins was inhibited after the administration of related pathway inhibitors. In summary, total ginsenosides may regulate the AMPK signaling pathway and activate the sirtuin 1 (SIRT1) peroxisome proliferator-activated receptor-gamma coactivator 1-alpha (PGC-1α) pathway to have therapeutic effects on depression.
