Methods: A total of 220 patients with essential hypertension treated in the Department of Cardiovascular Medicine of the First Affiliated Hospital of Bengbu Medical College were enrolled as the experimental group. According to left ventricular mass index (LVMI), patients with essential hypertension were divided into the non-left ventricular hypertrophy group (NLVH, n=108 cases) and the left ventricular hypertrophy group (LVH, n=112 cases). We used ELISA to detect the serum levels of IL-33 and sST2, the expression levels of IL-33 in peripheral blood lymphocytes of the NLVH group and the LVH group (60 cases each) were detected by Western blot, and the relationship between IL-33 and LVMI, a marker of left ventricular hypertrophic condition, was analyzed by Pearson. The relationship between IL-33, sST2 and left ventricular hypertrophy in essential hypertension was studied. Results: Compared with the NLVH group, the expression levels of IL-33 and sST2 in the LVH group were significantly increased. The results of Western blot showed that the expression level of IL-33 in the LVH group (1.07±0.08) was higher than that in the NLVH group (0.63±0.05) (P<0.05). Pearson correlation analysis showed that IL-33 was positively correlated with LVMI, sST2 was positively correlated with LVMI. Conclusion: The levels of IL-33 and sST2 in serum and the expression levels of IL-33 protein in peripheral blood lymphocytes are significantly increased in patients with hypertensive left ventricular hypertrophy, and the occurrence and development of essential hypertensive left ventricular hypertrophy may be related to IL-33 and sST2.

Methods: Gene expression omnibus (GEO) was used to retrieve the entry of "Liver hepatocellular carcinoma", and GSE109903 chip data was downloaded. The differentially expressed genes in the control group and liver hepatocellular carcinoma group were screened by bioinformatics analysis. GO enrichment analysis, KEGG pathway analysis, differential gene expression analysis and visualization processing were performed for the differentially expressed genes; Protein interaction network analysis and visualization processing were used to screen core genes EEF1A1 and HK2 with strong correlation with liver hepatocellular carcinoma. GEPIA, Kaplan-Meier plotter, GeneMANIA and Timer 2.0 databases were used to analyze the differential expression, prognostic value and immune cell infiltration of key genes in LIHC. Results: A total of 1059 differentially expressed genes were screened, including 637 up-regulated genes and 872 downregulated genes. Functional analysis showed that differentially expressed genes were mainly involved in the process of positive transcription regulation, nucleosome function, chromatin function and RNA binding. Pathway analysis showed that differentially expressed genes were involved in systemic lupus erythematosus, alcoholism and RNA polymerase I promoter opening pathway. The analysis of differential gene expression showed that the drugs with similar gene characteristics were mainly CDC inhibitors, prostaglandins, serotonin receptor antagonists, BAF transcriptional repression inhibitors, tyrosine phosphatase inhibitors, etc; Protein interaction network analysis showed that the main genes associated with LIHC were EEF1A1, HK2, FAM38A and LAMB3; EEF1A1 and HK2 genes were further analyzed by GEPIA. The results showed that the expression of EEF1A1 and HK2 mRNA in LIHC tissues was higher than that in normal tissues, and was significantly correlated with the pathological stage, overall survival rate and disease-free survival rate of LIHC patients. EEF1A1 and HK2 may be potential prognostic biomarkers for LIHC patients. In addition, the functions of EEF1A1 and HK2 were mainly related to translation factor activity, molecular chaperone mediated autophagy and carbohydrate catabolism, and purine nucleoside diphosphate metabolism, respectively. Immunocyte infiltration showed that the expression of EEF1A1 and HK2 was significantly correlated with the infiltration of a variety of immune cells, including six types of immune cells: CD4+T cells, macrophages, neutrophils, B cells, CD8+T cells and dendritic cells. Conclusion: By screening differentially expressed genes, we can identify the key genes in the development of liver hepatocellular carcinoma, and screen potential prognostic biomarkers for the survival of patients with liver hepatocellular carcinoma. At the same time, this study provides new ideas and programs for clinical treatment of liver hepatocellular carcinoma.

    查看更多>>摘要:Bronchial asthma (asthma for short) is a common chronic respiratory disease inchildren, which has adverse effects on children's physical and mental health. Nuclear factor κB (NF-κB) signaling pathway is an important transcription factor in airway inflammation, and plays an important role in airway inflammation and airway remodeling in asthma. Clinical studies have found that traditional Chinese medicine has positive effects in the treatment of asthma. Hence, this paper aims to review the literatures on the treatment of asthma through traditional Chinese medicine compound and single herbs and extracts by regulating the NF-κB signaling pathway for nearly a decade. It is found that traditional Chinese medicine can inhibit airway inflammation, relieve airway smooth muscle spasm and reduce airway resistance through the regulation of NF-κB signaling pathway, so as to play a key role in the treatment of asthma, and provide a scientific basis for the treatment of asthma with traditional Chinese medicine.
