Gout is a metabolic disease closely associated with hyperuricemia and urate deposition. Because of the complex pathogenesis， high morbidity， multiple complications， and increasingly young patients， gout has received worldwide attention. Currently， western medicine mainly treats gout by lowering the uric acid level and reducing inflammation， which， however， causes serious adverse reactions and has contraindications. Phellodendri Chinensis Cortex （PCC） is the dried bark of Phellodendron chinense， with the effects of clearing heat， drying dampness， purging fire， detoxifying， and treating sores. Studies have shown that PCC and its active components have anti-inflammatory， pain-relieving， uric acid-lowering， and anti-gout activities， with extensive sources and high safety. PCC and its active components could prevent and treat gout through multi-targets and multi-pathways， whereas the systematic review remains to be carried out. Therefore， this paper summarized the pharmacological activities and mechanisms of PCC and its active components in the treatment of gout. The available studies have shown that PCC and its active components exert the anti-gout effect by lowering the uric acid level， reducing inflammation， alleviating oxidative stress， and regulationg intestinal flora， and protecting the kidneys. Particularly， the active components represented by alkaloids contribute obviously to the therapeutic effect of of PCC. Herein， we analyzed the problems and future development of the research on PCC， aiming to provide theoretical support and a scientific basis for the research and development of new drugs against gout.

AIM:In this study,bioinformatics tech-nology was used to explore the differentially ex-pressed genes in antibody-mediated rejection after renal transplantation,and to screen out the possi-ble mechanisms and potential therapeutic targets of AMR-related miRNAs after renal transplantation,in order to provide new idea for the targeted thera-py of AMR after transplantation.METHODS:The dataset GSE115816 was downloaded from the GEO database,and the differential expression of miR-NAs in stable renal transplantation(SGF)group and the antibody-mediated rejection(AMR)group after renal transplantation was analyzed online by using DESeq 2R software.TargetScan software predicted the related targets of miRNAs,and the differential-ly expressed genes(DEGs)were analyzed through through gene ontology(GO)enrichment analysis and Kyoto gene and genome encyclopedia(KEGG)enrichment analysis,then key genes were screened by String database and Cytoscape,and finally veri-fied by TargetScan online analysis.RESULTS:A total of 10 differentially expressed miRNAs were identi-fied in the AMR group by comparison with the SGF group,with the most significant difference in ex-pression of miR-144-5p.A total of 143 miR-144-5p related targets were predicted by Targetscan soft-ware.GO analysis showed that DEGs were mainly involved in angiogenesis,synaptic signaling,and transcriptional co-activator regulation.KEGG analy-sis showed that DEGs were mainly enriched in the thyroid hormone signaling pathway,human papillo-mavirus infection,and PI3K-AKT signaling pathway.The 10 Hug genes were screened by PPI network.Based on the 6 algorithms in cytoHubba,5 key genes were obtained by taking the intersection of the top 10 Hug genes of each algorithm,which were NCOA2,NCOA1,FOXO1,PAX3,and PPARGC1A.After the literature review,we found that FoxO1 plays an essential role in immune sys-tem diseases and kidney diseases.In our study,we chose FoxO1 as a potential target protein for miR-144-5p.Finally,TargetScan online analysis showed that miR-144-5p has a targeted binding site with the 3'UTR region of FoxO1.CONCLUSION:MiR-144-5p plays an important role in AMR after Kidney transplantation.MiR-144-5p targeting FoxO1 may be a potential therapeutic target and prognostic biomarker for AMR.

Objective To explore the assessment system of humanistic communication in the grad-uation examination of pediatric residents. Methods A humanistic communication assessment program and an evaluation form were designed and put into practice in the graduation examination of pediatric residents in 2016 and 2017 in Beijing Children's Hospital affiliated to Capital Medical University and the scores were collected and analyzed to compare the differences in pediatric residents who have undergone system-atic physician-patient communication scene training and who didn't. With this analysis, the assessment system was further improved. Results Of all the 5 dimensions, communication content, nonverbal skills, and communication effects and the comparison of their respective scores were statistically significant. The scores of the residents who have undergone systematic physician-patient communication scene training are much better than those who didn't. Conclusion This assessment system focuses on the investigation of ability. From the design of examination questions and assessment scenes, to the evaluation of students per- formances, only when candidates have mastered the skills of communication can they do well in examina-tions and achieve good results.
