ABSTRACT
AIM:To explore the anti-ulcerative colitis mechanism of Buzhongyiqi pills based on the network pharmacology and experimental verification. METHODS: UPLC-QE-MS was used for qualitative analysis of Buzhongyiqi pills. Targets of the chemistry constituents and the disease were retrieved from GeneCards. Then the protein-protein interaction (PPI) network was constructed and core targets were screened for GO term enrichment and KEGG pathway enrichment. Ulcerative colitis mouse model was established to verify the key targets. RESULTS: A total of 41 constituents migrating of Buzhongyiqi pills were identified. A total of 123 common targets of the constituents and the disease and 24 core targets were screened out.KEGG enrichment and PPI network analysis showed that Buzhongyiqi pills may play a role in the treatment of ulcerative colitis through Akt, PI3K and other pathways. Furthermore, the results of animal experiments showed that Buzhongyiqi pills could significantly improve the depression behaviors of ulcerative colitis, reduce the levels of IL-6 and TNF-α in serum, inhibition Akt/PI3K signaling, and reduce the protein expression of PI3K. CONCLUSION: Buzhongyiqi pills may play a role in the treatment of ulcerative colitis by inhibition Akt / PI3K signaling pathway, and inhibiting PI3K and reduce the levels of IL-6 and TNF-α in the mice.
ABSTRACT
OBJECTIVE To analyze chemical components of Shenqi tiaoshen formula （SQTS）. METHODS UPLC-QE-MS method was adopted. The determination was performed on ACQUITY UPLC BEH C18 column with mobile phase consisted of 0.1% formic acid solution-0.1% formic acid acetonitrile solution （gradient elution） at the flow rate of 0.4 mL/min. The column temperature was set at 40 ℃ ， and the sample size was 5 μL. The electrospray ionization source was used to scan positive and negative ions， and the scanning range was m/z 100-1 500. Combined with TCMSP， PubChem and other databases， SQTS active component database was established and the components were identified in combination with relevant literature. RESULTS & CONCLUSIONS Totally 131 chemical components were identified from SQTS， including 23 terpenoids， 22 flavonoids， 21 phenylpropanoids， 12 alkaloids， 11 phenols， 9 amino acid derivatives， 4 fatty acyls， 3 organic acids and others， such as rutin， citrinin， synephrine， cinnamic acid and ginsenoside Rg1，etc. The cracking process of the main components involved the breaking of glycosidic bonds， dehydration， etc.
