Objective:To screen the interacting protein of ubiquitin-conjugating enzyme E2S(UBE2S)and construct the hepatocellular carcinoma(HCC)based on UBE2S interacting protein prognosis model(UIPM),and to discuss the value of UIPM in assessing the prognosis of the HCC patients.Methods:Co-immunoprecipitation(Co-IP)was used to screen the protein complexes binding to Flag-UBE2S.After validation by sodium dodecyl sulphate-polyacrylamide gel electrophoresis(SDS-PAGE)and Western blotting methods;liquid chromatography-mass spectrometer(LC-MS)was used to identify the UBE2S interacting proteins;Gene Ontology(GO)functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis were conducted on these proteins;the prognosis-related proteins from The Cancer Genome Atlas(TCGA)were cross-referenced with UBE2S interacting proteins by survival package of R software;the key proteins were extracted through LASSO regression analysis to build the UIPM;the prognostic model risk scoring formula was established.The HCC patients in TCGA were divided into high risk group and low risk group based on median value of the risk scores.The predictive accuracy of UIPM was evaluated by receiver operating characteristic curve(ROC),and the predictive accuracy was further validated by International Cancer Genome Consortium(ICGC)Database;univariate regression analysis and multivariate Cox regression analysis were used to detect whether the UIPM risk score was an independent prognostic factor for HCC.Furthermore,the nomogram model was built.Results:A total of 97 UBE2S interacting proteins were identified through Co-IP combined with LC-MS analysis.The GO functional enrichment analysis and KEGG signaling pathway enrichment analysis results showed that the interacting proteins were closely associated with cysteine-type endopeptidase activity,oxidative stress,and cell death.The TCGA revealed 5 163 HCC prognosis-related proteins;after intersecting with UBE2S interacting proteins,40 prognosis-related interacting proteins were found.Seven key proteins were determined through LASSO regression analysis,including UBE2S,heat shock protein family A member 8(HSPA8),heterogeneous nuclear ribonucleoprotein H1(HNRNPH1),chaperonin containing TCP1 subunit 3(CCT3),eukaryotic translation initiation factor 2 subunit 1(EIF2S1),receptor for activated C kinase 1(RACK1),and actin related protein 2/3 complex subunit 4(ARPC4),and the UIPM was constructed.There was significant difference in survival rate of the patients between high risk group and low risk group(P<0.05).The ROC curve analysis results showed the area under ROC curve(AUC)values of UIPM for predicting 1-year,2-year,and 3-year survival risk scores of the HCC patients were all greater than 0.7,indicating the model had high predictive accuracy.This was also confirmed by ICGC Database data.The univariate and multivariate Cox regression analysis results showed that the UIPM risk score was an independent prognostic risk factor for the HCC patients(P<0.05).The nomogram results showed good consistency between predicted survival rate and actual survival rate of the patient.Conclusion:A total of 97 interacting proteins that interact with UBE2S may promote the occurence and devolopment of HCC through oxidative stress and dysregulation of ferroptosis pathways.The UIPM risk score is an independent risk factor for the prognosis of HCC and can be used to predict the outcomes of the patients.UBE2S,HSPA8,HNRNPH1,CCT3,EIF2S1,RACK1,and ARPC4 could be regarded as the new biomarkers and therapeutic targets for HCC.

Abstract: To investigate the main occupational hazards of sand casting process enterprises, so as to provide insights into occupational disease prevention and control. Methods: In 2021 and 2022, six typical ferrous metal casting enterprises using sand casting technology in Wenling City, Zhejiang Province were selected to investigate the production processes and equipment, the operation of occupational disease prevention facilities and personal protective equipment. Occupational hazards including silica dust, noise, high temperature and ultraviolet radiation were detected and analyzed. Results: Six sand casting enterprises had not effectively set up and use occupational disease prevention equipment, and some employees had not worn personal protective equipment as required. The participation rate of occupational health examination was 100.00%. Among the 54 silica dust sampling points at the sand mixing, molding, sand falling, shot blasting and mud core drilling positions, the overall dust concentration exceeding the standard rate was 100.00%, and the respiratory dust exceeding the standard rate was 44.44%. Among the 55 noise measurement points at the sand mixing, sand falling, shot blasting, mud core drilling, polishing and blowing positions, 51 exceeded the standard, with a rate of 92.73%. Among the 90 sampling points for melting, painting, polishing, blowing and welding positions, the concentrations of welding fumes, manganese and its compounds, ethyl acetate and other cahmical factors did not exceed the standard. Six ultraviolet radiation measurement points in the welding position and six heat stress measurement points in the melting position did not exceed the standard. Conclusion The main occupational hazards of sand casting process enterprises in Wenling City are silica dust and noise, and occupational disease prevention and control should be further strengthened.

Isolation rearing (IR) enhances aggressive behavior, and the central serotonin (5-hydroxytryptamine, 5-HT) system has been linked to IR-induced aggression. However, whether the alteration of central serotonin is the cause or consequence of enhanced aggression is still unknown. In the present study, using mice deficient in central serotonin Tph2 and Lmx1b, we examined the association between central serotonin and aggression with or without social isolation. We demonstrated that central serotonergic neurons are critical for the enhanced aggression after IR. 5-HT depletion in wild-type mice increased aggression. On the other hand, application of 5-HT in Lmx1b mice inhibited the enhancement of aggression under social isolation conditions. Dopamine was downregulated in Lmx1b mice. Similar to 5-HT, L-DOPA decreased aggression in Lmx1b mice. Our results link the serotoninergic system directly to aggression and this may have clinical implications for aggression-related human conditions.

Recently, with the development of RNA research techniques, a wide variety of circular RNAs (circRNAs) have been discovered and some of them are confirmed to have crucial biological functions. CircRNAs arise from exons (i.e. exonic circRNAs) or introns (i.e. intronic circRNAs). Acting as microRNA sponges or combining with proteins, circRNAs participate in the regulation of gene expression and influence the activity of some proteins. In addition, some circRNAs even encode proteins. More importantly, several circRNAs play a key role in the occurrence and progression of some tumors, including stomach, liver, colon, breast, cervical, and ovarian cancers. Therefore, circRNAs may be a novel type of diagnostic marker and therapeutic target of cancers.
