Objective:To monitor adherence to specific sublingual immunotherapy (SLIT) in patients with seasonal allergic rhinitis(AR), analyse factors influencing adherence, and provide research support to effectively improve adherence. Methods:Patients with AR who underwent Artemisia pollen SLIT at the Department of Otolaryngology-Head and Neck Surgery, First Hospital of Shanxi Medical University from May 2021 to April 2022 were retrospectively followed up by telephone to investigate the current status of treatment, count the causes of shedding, and extract relevant information from their medical record data for analysis. Results:Of the 112 patients surveyed, 34 discontinued treatment(30.3%); patients who experienced adverse reactions and SLIT patients who had been on treatment for more than 6 months showed relatively good adherence(P<0.05). The main reasons for discontinuation in patients who dropped out were: asymptomatic discomfort during the non-pollen phase and therefore discontinuation of treatment or feeling that treatment was ineffective 9 cases(26.5%), forced discontinuation due to vaccination or pregnancy, or epidemics 6 cases(17.6%). Conclusion:Long-term adherence of patients to Artemisia pollen SLIT still needs to be brought to the attention of healthcare professionals, especially in the early stages of treatment when good patient education and good channels of trust and communication between doctors and patients need to be established.

Objective To explore the mechanism of hydroxyl safflower flavin A(HSYA)in the treatment of sepsis-induced liver injury by using metabolomics and network pharmacology.Methods A total of 50 male C57BL/6 mice were randomly divided into sham-operation group(10 mice),sepsis group(20 mice)and HSYA group(20 mice).Cecal ligation and puncture was conducted to establish the sepsis-induced liver injury mouse model.The mice in HSYA group were subcutaneously injected with HSYA after 2 hours of modeling.The content of serum inflammatory factors and liver function were detected,and the pathological changes of liver tissue were observed with HE staining,UPLC-Q-TOF-MS metabolomics was used to analyze liver tissue,screening for differential metabolites using multivariate statistical methods,network pharmacology was used to predict potential targets for HSYA treatment of sepsis-induced liver injury,and conduct GO and KEGG pathway enrichment analysis on potential targets,Metabo Analyst 5.0 database was used to match differential metabolites and potential targets between the model group and HSYA group,a targets metabolite-metabolism pathway network was constructed.AutoDock Vina software was used to perform molecular docking between HSYA and core genes,and finally RT-qPCR was used to verify the expression of core genes.Results HSYA can reduce the contents of IL-6,IL-1β and TNF-α in serum,restore liver function,and alleviate the morphological alternation in liver induced by sepsis.A total of 26 differential metabolites identified by metabolomics were screened out,including flufenamic acid,cryptolepine,opthalmic acid,fenpropathrin etc.,which were mainly involved in 5 metabolic pathways such as biosynthesis of unsaturated fatty acids and alpha-linolenic acid metabolism.Network pharmacology identified 81 potential targets,2 735 items enriched in GO and 124 signaling pathways enriched in KEGG;a total of 5 differential metabolites were matched for joint analysis,corresponding to 14 targets including IL1B,STAT3,PTGS2,TP53,etc.,involved in the regulation of metabolic disorders in sepsis-induced liver injury by HSYA.Molecular docking results showed that HSYA had good binding activity to IL1B,STAT3,PTGS2 and TP53 targets.RT-qPCR results showed that HSYA could inhibit the expressions of IL1B,STAT3 and PTGS2 in liver tissue.Conclusions HSYA may inhibit the release of inflammatory cytokines,maintain metabolic homeostasis,and alleviate sepsis-induced liver injury through modulating the expressions of IL1B,STAT3,and PTGS2.
