It defines the essential components and functional specifications for public service platforms, focusing on public needs such as electronic vaccination record management, appointment management, the promotion of electronic vaccination certificates, vaccination certificate verification for school enrollment, vaccination site navigation, and science communication and public engagement. The recommendations aim to serve as a reference for the development of vaccination public service platforms nationwide.

Objective To investigate the correlation between single nucleotide polymorphisms(SNPs)of the EGF gene,including rs11569017(A>T),rs2237051(A>G),rs3733625(C>T),and rs4444903(A>G),and the risk of non-small cell lung cancer(NSCLC)in a Han population of Yunnan.Methods A total of 439 patients with NSCLC and 520 healthy controls were recruited in Yunnan Province between January 2022 and December 2023.Genotyping of four SNP loci in the EGF gene was performed using TaqMan probes,followed by analysis of allele,genotype,genetic model,and haplotype distribution frequencies between NSCLC and control groups.Stratified analyses were further conducted based on NSCLC pathological types and clinical stages.Results The rs2237051 locus showed significant differences in allele(P=0.011)and genotype(P=0.042)frequencies between the squamous cell carcinoma(SCC)group and the control group.The frequency of the A allele was lower in the SCC group than in the control group(OR=0.71,95%CI 0.54～1.85),but there was no difference after Bonferroni correction(P>0.0125).Under the log-additive model,the rs2237051-2G/G+A/G genotype was associated with an increased risk of SCC(P=0.01;OR=1.42,95%CI 1.08～1.86).However,the association lost statistical significance after Bonferroni correction(P>0.0125).The haplotype rs11569017-rs2237051-rs3733625-rs4444903 has no difference between the two groups(P>0.0125).The stratified analysis revealed no significant associations between the genetic loci and different disease stages(P>0.0125).Conclusion In the Yunnan Han population,the individuals carrying the rs2237051-A allele of the EGF gene have a significantly lower risk of squamous lung cancer,but further functional experiments are needed to verify the protective mechanism.

Objective To identify potential biomarkers for proliferative diabetic retinopathy(PDR)using proteomics and transcriptomics data.Methods In this study,the proteomics dataset(PXD046630)and two transcriptomics datasets(GSE60436 and GSE102485)were derived from the aqueous humor samples and fibrovascular membranes of PDR patients,respectively.Differentially expressed genes(DEGs)were identified via R software,specifically the limma and edgeR pack-ages.The shared DEGs between PXD046630 and GSE60436 were analyzed via protein-protein interaction(PPI),Gene On-tology(GO)enrichment,and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analyses.The key DEGs were validated in GSE102485 via receiver operating characteristic(ROC)curve analysis.A quantitative polymerase chain reaction(qPCR)assay was used to confirm the mRNA of these candidate biomarkers in human retinal microvascular endothelial cells(HRMECs)cultured in high glucose and low oxygen conditions.Results A total of 59 shared DEGs and 26 hub genes were identified from the PXD046630 and GSE60436 datasets.KEGG analysis revealed that six pathways,inclu-ding extracellular matrix-receptor interaction,proteoglycans in cancer,and complement and coagulation cascades,were enriched in 12 key DEGs.Fibronectin 1(FN1),tissue inhibitor of metalloproteinase 3(TIMP3),complement factor H(CFH),decorin(DCN),and lipoprotein receptor-related protein-2(LRP2)were identified as potential biomarkers on the basis of their AUC values being greater than 0.900(CI≥95％).The mRNA expression levels of FN1,CFH,and LRP2 were significantly increased in HRMECs cultured in high glucose and low oxygen conditions.Conclusion FN1,CFH,and LRP2 are potential biomarkers for PDR,and further studies are needed to explore their roles and therapeutic potential in PDR.

Objective To investigate the association between four single nucleotide polymorphisms(SNP)(rs9340 in MAPK1,rs14804 in NRAS,rs712 and rs7973450 in KRAS)in the 3'UTR of ERK1/2 signaling pathway-related genes and non-small cell lung cancer(NSCLC).Methods A total of 478 NSCLC patients and 480 healthy controls were enrolled in this study.Four SNPs were genotyped by using TaqMan assays.The association between the four SNPs and NSCLC was analyzed.Results The distribution frequency difference of the allele of rs9340 was statistically significant between the control group and the non-small cell squamous cell carcinoma(SCC)group(P = 0.009),suggesting that the G allele of rs9340 may be a protective factor for non-small cell lung squamous cell carcinoma(OR = 0.67,95%CI:0.50～0.91).In addition,in the<50 years age group,the distribution frequency difference of the allele of rs9340 was statistically significant between the control group and the NSCLC group(P = 5.07×10-4),indicating that the G allele of rs9340 may be a protective factor for NSCLC(OR = 0.46,95%CI:0.29～0.72).Conclusion The SNP rs9340 in MAPK1 may be associated with the risk of NSCLC.

Objective To analyze the short-term clinical efficacy and prognosis of one-stop transcatheter aortic valve replacement (TAVR)+percutaneous coronary intervention (PCI) in the treatment of aortic valve disease with coronary heart disease. Methods The clinical data of patients with aortic valve disease complicated with coronary heart disease who underwent one-stop TAVR+PCI treatment at the Department of Cardiovascular Surgery, the Second Hospital of Hebei Medical University from January 2018 to June 2023 were retrospective analyzed. The preoperative and postoperative clinical data were compared, and 1-month follow-up results were recorded. Results A total of 37 patients were enrolled, including 22 males and 15 females, with an average age of 69.14±6.47 years. Thirty-six patients recovered and were discharged after the surgery, and 1 (2.7%) patient died during the surgery. Self-expanding TAVR valves were implanted through the femoral artery in all patients. One coronary artery was opened by PCI in 35 (94.6%) patients, and two coronary arteries were opened by PCI in 2 (5.4%) patients. All PCI opened arteries had a stenosis>70%. During the postoperative hospitalization, the complications included pulmonary infection in 11 (30.6%) patients, severe pneumonia in 10 (27.8%) patients, liver function injury in 14 (38.9%) patients, renal function injury in 5 (13.9%) patients, cerebral infarction in 1 (2.8%) patient, atrial fibrillation in 1 (2.8%) patient, ventricular premature beats in 2 (5.6%) patients, atrioventricular block in 2 (5.6%) patients, and complete left bundle branch block in 5 (13.9%) patients. The median postoperative ventilation assistance time was 12.0 (0.0, 17.0) h, the ICU monitoring time was 1.0 (0.0, 2.0) d, and the postoperative hospitalization time was 5.0 (4.0, 7.0) d. There was a significant improvement in the New York Heart Association cardiac function grading after surgery (P<0.001). After surgery, there were 21 (58.3%) patients had minor perivalve leakage, 6 (16.7%) patients had minor to moderate perivalve leakage, and no moderate or above degree of perivalve leakage. After one month of postoperative follow-up, 36 patients showed significant improvement in heart function. There were no patients with recurrent acute coronary syndrome, re-PCI, or cardiovascular system disease related re-hospitalization. Conclusion The one-stop TAVR+PCI treatment for patients with aortic valve disease and coronary heart disease can obtain satisfactory short-term clinical efficacy, which is worth further trying and studying.

Objective To investigate the expression of the ubiquitination enzyme UBE2S in different cell types in hepatocellular carcinoma(HCC)microenvironment and its impact on proliferation and stemness of HCC cells.Methods TCGA and CPTAC database were used to analyze the transcriptional and promoter methylation levels and protein expressions of UBE2S in HCC.Specific expression patterns of UBE2S,intercellular communication and key transcription factors in different cell types were analyzed based on single-cell sequencing data from TISCH website.We further examined UBE2S expressions in clinical samples of HCC tissues,HCC cells and T cells using immunohistochemistry and immunofluorescence staining.We also tested the effects of UBE2S knockdown on stemness of HCC-LM3 and HepG2 cells using clone formation experiments and sphere formation assay.Results Analysis based on TCGA database suggested significant overexpression of UBE2S in both paired and non-paired tumor tissues(P<0.001),and its transcriptional level increased with tumor grades.The methylation level of UBE2S promoter was significantly decreased in HCC(P<0.001),and its transcription level increased obviously in HCC with TP53 mutation(P<0.001).Analysis of CPTAC database also demonstrated overexpression of UBE2S protein in HCC tissues(P<0.001).Three prognostic models suggested that HCC patients with high UBE2S expression had poorer prognosis(P<0.001).Single-cell sequencing data analysis revealed high expressions of UBE2S in T cells and high intensities of interaction between endothelial cells,epithelial cells and fibroblasts in HCC microenvironment.Immunohistochemistry and immunofluorescence staining demonstrated high UBE2S expressions in clinical samples of HCC tissues,HCC cells and T cells.In HCC-LM3 and HepG2 cells,UBE2S knockdown significantly inhibited cell clone formation and tumor sphere formation(P<0.05).Conclusion UBE2S is highly expressed in T cells in HCC microenvironment in close correlation with a poor prognosis.High UBE2S expression promotes the stemness of HCC cells.
