Abstract:
Objective To study the effect and possible mechanism of Siraitiae fructus Qingyan Formula(SQF)on acute pharyngitis(AP)rats induced by ammonia water.Methods The active ingredients and targets of SQF were obtained from TCMSP database,pharyngitis targets were acquired from disease databases such as DrugBank,and the common targets were identified through intersections.Constructing protein-protein interaction(PPI)networks to obtain key targets.GO and KEGG enrichment analysis were carried out,and the"active ingredients-targets-pathways"network was constructed.Discovery Studio 2019 was used for molecular docking of active ingredients.The acute pharyngitis model was induced by fixed point quantitative application of ammonia water.After Siraitiae fructus Qingyan oral thick paste(SQP)low-,medium-and high-dose(4,8,16 g/kg)administration,The body mass,general behavior and symptoms of the rats were monitored continuously,and the score of pharyngeal swelling was recorded;the pathological changes of pharyngeal were observed by HE staining.The classification and the count of inflammatory cells were determined.The expression of inflammatory factors(IL-6,IL-1β,PGE2)and PI3K-AKT signaling pathways in pharyngeal tissues were assessed by quantitative real-time polymerase chain reaction(qRT-PCR).Results A total of 35 active ingredients,223 action targets and 2549 pharyngitis related targets were obtained through network pharmacology,with 153 common targets in total.The key targets were protein kinase B(PKB or AKT).Pathways involved PI3K-AKT signaling pathway.Combined with key targets,it was speculated that PI3K-AKT is an important signaling pathway for the treatment of acute pharyngitis with SQF.Compared with the model group,the related symptoms of AP rats were alleviated after the treatment of SQP.The redness and swelling of pharynx were significantly improved(P<0.001).The hyperplasia of the upper mucosa of pharyngeal was alleviated or disappeared,infiltration of a small amount of inflammatory cells,and hypertrophy and hyperplasia of submucosa glandular cells were alleviated.The numbers of inflammatory cells in blood of rats significantly decreased(P<0.05).And the mRNA expression levels of IL-6,IL-1β and PGE2 in pharyngeal tissues were significantly decreased(P<0.05,P<0.01,P<0.001),while the mRNA expression levels of PI3K,AKT and mTOR mRNA were remarkably raised(P<0.05,P<0.01).Conclusion SQF has obvious improvement effect on AP rats,and its mechanism may be related to reducing inflammation level,improving pharyngeal mucosa hyperplasia,inflammatory cells infiltration,hypertrophy and hyperplasia of submucosal glandular cells,and regulating PI3K-AKT signaling pathway.
