Depression is a high-incidence mental disorder with complex causes and multifaceted pathogenic mechanisms. Its pathogenesis has not yet been fully elucidated， which has hindered the development of novel and highly effective antidepressant drugs. This condition severely affects human physical and mental health while imposing a significant socio-economic burden. At present， several hypotheses exist regarding the pathogenesis of depression， including monoamine neurotransmitter imbalances， neurotrophic factor deficiencies， neural plasticity impairments， glutamate dysregulation， neuroinflammatory disorders， gut microbiota imbalances， and mitochondrial autophagy dysfunction. Currently， most clinical antidepressants are monoamine neurotransmitter reuptake inhibitors. Although they exhibit certain therapeutic effects， they are associated with significant drawbacks， such as severe adverse reactions and poor patient compliance. In contrast， traditional Chinese medicine （TCM）， characterized by its multi-targeted effects， mild efficacy， and minimal side effects， has demonstrated significant advantages in the treatment of depression. Chinese medicine Polygalae Radix possesses the functions of calming the mind， enhancing cognitive functions， harmonizing the heart and kidneys， and dispelling phlegm to open orifices. It is often included in compound prescriptions for the clinical treatment of depression. Based on current hypotheses regarding the pathogenesis of depression， this paper systematically reviews research progress on the antidepressant mechanisms of Polygalae Radix from multiple perspectives， including its active components， its use in herbal pairings， and its inclusion in TCM compound prescriptions. This review aims to provide a scientific basis for the clinical application of Polygalae Radix in antidepressant therapy and to serve as a reference for the modernization of its antidepressant research.

Abstract In April 2021, type Ⅰ vaccine-derived poliovirus (VDPV) was detected from two fecal samples of a male infant with acute flaccid paralysis (AFP) in Zhejiang Province when he was admitted to the Children's Hospital Affiliated to Fudan University in Shanghai, with 12 and 14 nucleotide mutations in the VP1 region, respectively. The case had a history of immunization with three doses of poliovirus vaccines, and grade Ⅲ proximal muscle strength and grade Ⅱ distal muscle strength of the right lower limb. After symptomatic treatment, the activity of the right lower limb and the muscle strength was significantly restored, thus he was discharged. VDPV was not detected from subsequent (the 8th to 12th) fecal samples of the case and fecal samples of close contacts. No similar cases were found in medical institutions in the county, surrounding areas, neighboring villages or towns. Since the case did not exhibit clinical symptoms of poliomyelitis caused by VDPV, poliomyelitis was excluded, and the case was diagnosed with hemophilia type A based on the epidemiological investigation, laboratory tests, and the history of poliomyelitis vaccination. This event involved cross-provincial (municipal) cooperation and was responsed promptly, preventing further spread of the virus. It suggested that the sensitivity of the AFP case surveillance system should be maintained, environmental monitoring methods should be increased, and the poliomyelitis vaccination should be promoted to prevent the spread of the virus.

Objective To screen for ferroptosis-related differentially expressed genes(DEGs)of epidermal growth factor receptor(EGFR)-tyrosine kinase inhibitors(TKIs)resistance in non-small cell lung cancer(NSCLC).Methods The gene sequencing dataset GSE117846 of NSCLC EGFR-TKIs resistant cells was se-lected from the Gene Expression Omnibus data base(GEO)and screened for DEGs with P＜0.05 and | log2 FC |1.Ferroptosis-related genes were collected using the FerrDb database and jvenn was used to intersected the DEGs screened from GSE117846 dataset with the ferroptosis-related genes obtained from FerrDb database.GO function and KEGG pathway enrichment analysis of intersection genes were performed,and protein-pro-tein interaction(PPI)network was drawn.The score of intersection genes was calculated by using Cytohubba plug-in in Cytoscape software,and the top 10 genes were used for Hub genes screening.ULCAN and GEPIA2 databases were used to analyze the expression of Hub genes in NSCLC and its effect on the survival prognosis of patients.Real-time fluorescence quantitative PCR(qPCR)was used to detect the relative expression levels of Hub gene mRNA in NSCLC patients'cancer tissues,adjacent tissues and in vitro cells to verify the results of bioinformatics analysis.Results A total of 60 ferroptosis-related DEGs of EGFR-TKIs resistance in NSCLC were screened out,including 30 up-regulated genes and 30 down-regulated genes.The 60 genes were mainly enriched in P53 signaling pathway,ferroptosis pathway and FoxO signaling pathway.There were 57 nodes and 99 edges in the PPI network,with an average clustering coefficient of 0.377 and PPI enrichment P＜0.01.The Hub gene screened out by Cytohubba plug-in was tumor protein P63(TP63).ULCAN and GE-PIA2 database analysis showed that the expression of TP63 in lung adenocarcinoma tissue was significantly lower than that in normal tissue,while the expression of TP63 in lung squamous cell carcinoma tissue was sig-nificantly higher than that in normal tissue,and the differences were statistically significant(P＜0.05).In pa-tients with lung adenocarcinoma,there was no significant difference in the survival prognosis between TP63 high and low expression groups(P＞0.05),while in patients with lung squamous cell carcinoma,the survival prognosis of TP63 low expression group was better,and the difference was statistically significant(P＜0.05).QPCR showed that TP63 mRNA highly expressed in lung squamous cell carcinoma tissue and lowly expressed in lung adenocarcinoma tissue compared with adjacent tissues(P＜0.05).The expression of TP63 mRNA was down-regulated in gefitinib-resistant PC9/GR cells(P＜0.05),which was consistent with the re-sults of bioinformatics analysis.Conclusion TP63 may be an important gene linking NSCLC EGFR-TKIs re-sistance to ferroptosis.

Objective By using the computational fluid mechanic(CFD)method the tandem carotid artery stenosis(TCAS)was simulated on the model,and to compare the postoperative hemodynamic changes of different surgical procedures.Methods One patient with tandem stenosis of internal carotid artery(ICA)and common carotid artery(CCA)was selected.CFD technique was used to establish four three-dimensional(3-D)models of the carotid bifurcations,including one model of a real patient and three models of presumptive surgery.The hemodynamic analysis was performed with these models so as to explore the development mechanism of TCAS and to discuss the selection of suitable surgical plan.Results In tandem stenosis,the stenosis was preferentially formed in CCA and subsequently led to ICA stenosis.The local hemodynamic situation in TCAS was more complex and more risky than in single carotid artery stenosis.In tandem stenosis,the treatment of one stenosis site would affect the blood flow at the next stenosis site and cause restenosis or plaque rupture.Conclusion In treating patients with TCAS,CFD simulation examination should be performed when the surgical plan is formulated,which can help clinicians to predict the postoperative changes in blood flow and to choose the appropriate surgical plan.
