RNA-binding protein human antigen R(HuR)is a protein product of the embryonic lethal abnormal vision gene(ELAVL).It is widely expressed in human cells and primarily regulates mRNA stability through post-transcriptional mecha-nisms,particularly by binding to AU-enriched elements(AR-Es).Recent studies have indicated that HuR interacts with non-coding RNAs to participate in the regulation of gene expression,including long non-coding RNAs,circular RNAs,microRNAs,and vault RNAs.The interactions between HuR and these ncR-NAs play a crucial role in the occurrence and development of va-rious diseases,including tumors.Since there are already reviews summarizing the research on tumors,this review mainly focuses on summarizing the role of HuR-ncRNA interactions in diseases other than tumors.

Objective:To explore the prognostic factors of seroma after endoscopic thyroidectomy by breast ap-proach,and construct a nomogram to predict the possibility of cervical seroma.Methods:Data of patients undergoing endoscopic thyroid surgery in Dongguan Tungwah Hospital from January 2022 to May 2024 and Dongguan Songshan Lake Tungwah Hospital from May 2023 to August 2024 were retrospectively analyzed,and 1493 patients meeting the in-clusion criteria were selected.Among them,there were 1048 patients in Dongguan Tungwah Hospital as the training co-hort,1015 patients without seroma group and 33 patients with seroma group.There were 445 patients in Dongguan Songshan Lake Tungwah Hospital as the verification cohort,including 424 patients without seroma and 21 patients with seroma.Multivariate logistic regression analysis was used to obtain relevant independent prognostic factors,and R soft-ware established a nomogram model.Calibration curves,Hosmer-Lemeshow goodness of fit,ROC curves were used to evaluate the calibrability of the nomogram model,and clinical utility was assessed by clinical decision curves.Results:Multivariate logistic regression analysis showed that central lymph node dissection,diabetes,hyperthyroidism,and nod-ule size were independent prognostic factors related to seroma.Based on the prognostic factors,the nomogram of se-roma after ETBA was constructed.The calibration curves of the training and the verification group were in good agree-ment with the observed results,and the Hosmer-Lemeshow goodness of fit test was good,with the training cohort P=0.244 and the verification cohort P=0.803.The ROC curve of the training cohort showed that the area under the curve was 0.810(95%CI:0.740～0.879),and the ROC curve of the verification cohort showed that the area under the curve was 0.815(95%CI:0.722～0.909).Conclusion:The nomogram model based on the relevant prognostic factors ob-tained by multivariate logistic regression analysis has a good prediction effect on the seroma after ETBA,and can provide reasonable and individualized treatment plan for patients.

Aim To explore the potential mechanisms underlying therapeutic effects of cordycepin in asthma by utilizing network pharmacology,molecular docking,and in vitro cellular validation.Methods The thera-peutic targets associated with asthma and the drug tar-gets of cordycepin were systematically identified through comprehensive database searches.An overlap analysis of the two gene sets was performed,followed by the construction of a protein-protein interaction(PPI)network and topological analysis to identify the core targets.The core targets were subjected to Kyoto Ency-clopedia of Genes and Genomes(KEGG)pathway a-nalysis and Gene Ontology(GO)enrichment analysis,and a drug-target-pathway network was constructed.To validate the interaction between cordycepin and core targets,molecular docking and molecular dynamics sim-ulations were conducted.Subsequently,the pharmaco-logical effects and underlying mechanisms of cordyce-pin were validated in vitro using Beas-2B cells,emplo-ying Cell Counting Kit-8(CCK-8)assay and quantita-tive real-time reverse transcription PCR(RT-qPCR).Results A total of 438 potential targets of cordycepin were identified,113 of which overlapped with asthma-related therapeutic targets.Topological analysis based on the PPI network revealed 22 core targets.Using KEGG enrichment analysis,165 significantly enriched pathways were identified,including the TNF and HIF-1 signaling pathways.Molecular docking analysis re-vealed high binding affinities between cordycepin and select core targets,which further corroborated by mo-lecular dynamics simulations.In vitro experiments showed that after cordycepin pretreatment,the upregu-lation of MAPK1,HIF1A,MTOR,MYC,IL10,and JUN mRNA was significantly rescued in HDM-stimulated Beas-2B cells.Conclusions Cordycepin exerts anti-asthmatic effects by targeting MAPK1 and other key molecules,thereby providing a scientific foundation for its further development and clinical application.

Objective To investigate the effects of scoparone(Sco)on proliferation and invasion of colon cancer cell line HCT116,and its effect on the expression of epidermal growth factor receptor(EGFR).Methods 1)HCT116 cells were divided into control group,50Sco group,100Sco group and 200Sco group.The cells in con-trol group were incubated with culture medium for 48 hrs.The 50Sco group,100Sco group and 200Sco group were incubated with 50,100 and 200 μmol/L scoparone for 48 hrs respectively.2)HCT116 cells were divided into con-trol group,NC-200Sco group,NC-LV+200Sco group and EGFR-LV+200Sco group.The control group was incuba-ted with normal culture medium for 48 hrs.NC-200Sco group was incubated with 200 μmol/L scoparone for 48 hrs.NC-LV and EGFR-LV were infected into HCT116 cells in NC-LV+200Sco group and EGFR-LV+200Sco group,then incubated with 200 μmol/L scoparone for 48 hrs.Cell proliferation was detected by MTT assay and EdU stai-ning,cell apoptosis was detected by flow cytometry and cell invasion was detected by Transwell assay.EGFR mRNA was detected by RT-qPCR,the level of EGFR,Bcl-2,Bax,matrix metalloproteinase(MMP)-2 and MMP-9 protein was detected by Western blot.Results Compared to the control group,the cell viability,proportion of EdU positive cells and counting number of invasive cells in 50Sco group,100Sco group and 200Sco group all decreased(P＜0.05).Cell apoptosis rate and Bax protein expression increased(P＜0.05),the protein expression of Bcl-2,MMP-2 and MMP-9 decreased(P＜0.05).mRNA and protein expression of EGFR were de-creased(P＜0.05).Compared with NC-200 Sco group and NC-LV+200Sco group,the expression level of mRNA and protein of EGFR in EGFR-LV+200Sco group was increased(P＜0.05).Cell viability,proportion of EdU posi-tive cells and counting number of invasive cells all increased(P＜0.05).The cell apoptosis rate and Bax protein expression level were decreased(P＜0.05).The protein expression of Bcl-2,MMP-2 and MMP-9 was increased(P＜0.05).Conclusions Scoparone has anti-colon cancer cell activity and inhibits proliferation as well as invasion of colon cancer cells through inhibition of EGFR.

Objective To explore the relationships of vitamin D and oxidized low-density lipoprotein(ox-LDL)with infertility in patients with polycystic ovary syndrome(PCOS)based on restricted cubic spline models.Methods A total of 150 PCOS patients were selected as the study subjects and followed up for at least 1 year.They were divided into infertile group and non-infertile group according to whether they were infertile.A Logistic regression model was used to analyze the influencing factors of infertility in PCOS patients.Furthermore,the relationships of 1,25-dihydroxyvitamin D3[1,25-(OH)2D3]and ox-LDL with infertility in PCOS patients,as well as their interactive effects on infertility in PCOS patients were analyzed.A restricted cubic spline model was used to analyze the non-linear relationships between 1,25-(OH)2D3,ox-LDL,and infertility in PCOS patients.Results Among 150 PCOS patients,78 were not pregnant,resulting in an infertility rate of 52.00％(78/150).Multivariate Logistic regression analysis showed that the severity of PCOS,body mass index,age,1,25-(OH)2D3,and ox-LDL were all independent influencing factors for infertility in PCOS patients(P＜0.05).After adjusting for confounding factors,1,25-(OH)2D3 and ox-LDL were still associated with the risk of in-fertility in PCOS patients(P＜0.05).Restricted cubic spline model analysis revealed non-linear rela-tionships between 1,25-(OH)2D3,ox-LDL,and the risk of infertility in PCOS patients(P＜0.05).When the serum 1,25-(OH)2D3 level was＜35.70 nmol/L,it was negatively correlated with the risk of infertility in PCOS patients(P＜0.05).When the serum ox-LDL level was ≥381.00 μg/L,it was positively correlated with the risk of infertility in PCOS patients(P＜0.05).Interactive effect analysis showed that 1,25-(OH)2D3 and ox-LDL had antagonistic effects on infertility in PCOS pa-tients(P＜0.05).Conclusion Decreased serum 1,25-(OH)2D3 levels and increased ox-LDL levels in PCOS patients can significantly increase the risk of infertility.Moreover,there is a non-lin-ear dose-response relationship and an antagonistic interactive effect between them,suggesting that regulating vitamin D and oxidative stress levels may be an important strategy for improving the fertili-ty outcomes of PCOS patients.

To investigate the in vitro inhibitory mechanism of Nymphaea candida total flavonoids(NCTF)against Staphylococcus aureus(S.aureus)and its safety in mice,this study first deter-mined the antibacterial effect of NCTF on the clinically isolated strain S.aureus-C1.Subsequently,the inhibitory mechanism of NCTF on S.aureus-C1 was explored by measuring its effects on bac-terial growth curves,microstructure,intracellular AKP and LDH levels,and biofilm formation.Safety evaluation included determination of LD50 and MDT in mice,as well as analysis of serum biochemical parameters,organ indices,and histopathological observations.Results showed that NCTF effectively inhibited S.aureus-C1 proliferation,with an inhibition zone diameter of(18.98±0.67)mm and a MIC of 6.25 g/L.A concentration of 2×MIC nearly completely suppressed bacte-rial growth.Scanning electron microscopy revealed structural damage to bacterial cells,including collapse and shrinkage.AKP and LDH assays indicated significantly increased AKP activity(P＜0.05)and decreased intracellular LDH activity(P＜0.05)in the supernatant of drug-treated groups,demonstrating NCTF-induced disruption of cell walls and membranes leading to leakage of AKP and LDH.Crystal violet staining of biofilms showed significant inhibition rates of(43.77±9.16)％and(61.71±9.82)％at 2 × MIC and 4 × MIC concentrations,respectively(P＜0.05).Safe-ty assessments indicated low toxicity of NCTF in mice,with transient effects that returned to nor-mal levels within a short period.These findings demonstrate that NCTF exhibits potent antibacte-rial activity against S.aureus-C1 by damaging bacterial cell structures,increasing cell wall/mem-brane permeability,reducing biofilm formation,and displaying low toxicity.This study provides scientific evidence for clinical drug screening against bovine mastitis and the development of Nym-phaea candida resources.

Objective To investigate the role of reactive oxygen species(ROS)and the extracellular signal-regulated kinase(ERK)/cAMP response element binding protein(CREB)signaling pathway in arsenic-induced apoptosis in HT-22 cells.Methods HT-22 cells were cultured in vitro and exposed to NaAsO2.The cells were divided into the following groups:control group,4,6,8,and 10 μmol/L NaAsO2 groups,NAC(5 mmol/L)group,and NAC(5 mmol/L)+NaAsO2(10 μmol/L)group.ROS levels were measured using a DCFH-DA assay.The expression of ERK/CREB signaling pathway-related and apoptosis-related proteins were analyzed by Western blotting.Apop-tosis rates were evaluated using flow cytometry.Results Compared with the control group,ROS levels in HT-22 cells significantly increased,while p-ERK protein level in the nucleus and p-CREB and Bcl-2 protein levels in the cells significantly decreased in the NaAsO2 only exposed groups(P＜0.05).Additionally,the apoptosis rate significantly increased in the 8 and 10 μmol/L NaAsO2 groups compared with the control group(P＜0.05).In the NAC+NaAsO2 group,ROS levels and the apoptosis rate significantly decreased while p-ERK protein level in the nucleus and p-CREB and Bcl-2 protein levels in the cells significantly increased compared with the 10 μmol/L NaAsO2 group(P＜0.05).Conclusion Arsenic exposure induces oxidative stress,inhibits the nuclear translocation of p-ERK,and dis-rupts the CREB signaling pathway,leading to apoptosis.
