Aim To explore the potential mechanism of Dangshen Pingfei Huoxue decoction (DPHD) in the treatment of pulmonary fibrosis. Methods The common targets of DPHD and pulmonary fibrosis were obtained. Cytoscape software was used to construct " disease-drug-ingredients-targets " network diagram, and the common targets were imported into the STRING database for protein-protein interaction (PPI) analysis to screen out the core targets. In order to screen out key signaling pathways, the core genes were inputted into the DAVID platform for gene ontology (GO) and kyoto encyclopedia of genes genomes (KEGG) enrichment analysis. Then the molecular docking technology was used to verify the molecular docking between the core components and the key proteins in the signaling pathway. Finally, the molecular docking technology was used to verify the results of network pharmacology. Results A total of 176 active ingredients were obtained, and the top 5 was quercetin, kaempferol, luteolin, naringenin and p-sitosterol, respectively. A total of 116 common targets were obtained. A total of 21 core targets were finally obtained by PPI screening, and the top 5 was AKT1, CCND1, CASP3, MYC and IL1B, respectively. The results of GO enrichment analysis showed that DPHD was mainly involved biological processes of oxidative stress, proliferation and differentiation, transcriptional regulation, drug response and inflammatory response. The results of KEGG enrichment analysis indicated that the mainly signaling pathways included PI3K/Akt, MAPK, cellular senescence, AMPK, and TGF-beta. Molecular docking results showed that the binding energies of the top 5 active components of DPHD and the top 5 core targets were all less than-6.0 kcal • mo
Résumé
Objective:To understand the cognition and behavior of drug safety in Beijing middle school students and provide advice for relevant education.Methods:A cross-sectional survey using paper questionnaires was carried out on the student body of nine Beijing middle schools.Multi-stage proportionate stratified cluster sampling was adopted to enroll participants.In addition to demographic questions,the questionnaire included 17 questions assessing the cognition and behavior of safe drug use,prioritizing questions that aligned with the health education guideline for primary and secondary school students from Chinese Ministry of Education.Descriptive statistical methods were applied using the SAS 9.2 software.Results:Of the 4 220 students investigated,2 097(49.7%) were males and 2 123(50.3%) were females.The average age was (14.3 ± 1.7) years.2 030(48.1%) students were from downtown areas,1 511(35.8%) were from urban-rural linking areas and 679(16.1%) were from rural areas.Half (51.5%) of the respondents were junior high school students,and the others were from senior high schools (34.2%) and vocational high schools (14.3%).Most of the students (89.6%) lived off campus.The awareness rate of drug safety knowledge was 74.4%,the median score of drug safety behavior was 4 points (full score was 5 points) and there was a statistically positive correlation between the two (Spearman's correlation coefficient was 0.156,P <0.001).Both the awareness rates and the drug safety behavior scores were statistically different among the students in different regions,different school types and different residence types (P < 0.001).Multiple factors analysis demonstrated the correlation between the cognition degrees of both drug safety knowledge,behavior and the above factors.Of all the students,80.4% agreed that any drug could have adverse drug reactions;40.5% were aware that antibiotics couldn't kill viruses;as many as 49.6% mistook aspirin as antibiotic;97.4% would read drug instructions before taking them;Only 42.4% put expired drugs into special recycling bins;49.8% would deviate from the suggested dosage and frequency of their medication when they were sick with common diseases.Conclusion:Overall,the cognition of drug safety in Beijing middle school students is good,but problems still exist in medication adherence,the management of expired drugs and the antibiotics cognition,which need to be fixed through specific,pointed way of education.And more efforts should be made to improve the cognition in rural regions,vocational high schools and on campus students.
