Objective:To analyze the effect of glucocorticoid on the biological function of lens epithelial cells (LECs) by bioinformatics and predict related microRNA (miRNA).Methods:GSE3040 database was downloaded and the human LECs line (HLE-B3) cells in the experimental group were treated with 1 μmol/L dexamethasone, and HLE-B3 cells in the control group were treated with 1 μmol/L dimethyl sulfoxide(DMSO).GEO2R was used to analyze the differentially expressed genes between the two groups.Metascape website was employed to analyze the functional enrichment of differentially expressed genes, and EdU cell proliferation assay was performed to detect the difference in cell proliferation between the two groups.STRING website and cytoscape software were used to construct protein-protein interaction network.Hub genes were calculated by cytohubba app, and quantitative real-time PCR was performed to detect the expression levels of hub genes between the two groups.MirCode website was used to predict the related miRNAs.Results:A total of 341 differentially expressed genes were detected between the experimental group and the control group, among which there were 300 up-regulated genes and 41 down-regulated genes. SLC12A1, MED13L, ALDH5A1, SLC15A3 and WWC1 were the top five down-regulated genes and SCNN1A, ANKRD36, FKBP5, PYY and ADH1B were the top five up-regulated genes.The top 20 terms of functional enrichment were listed, and the negative regulation of HLE-B3 cells proliferation showed the most enrichment.Cell proliferation rate in the experimental group was (8.09±0.20)%, which was significantly lower than (39.63±0.80)% in the control group ( t=38.43, P<0.01).The top ten hub genes were SST, CXCL8, GRM1, GNRH1, CXCL5, PPBP, CX3CR1, PYY, EDNRA and GRK5, and quantitative real time PCR confirmed that the expression levels of SST, CXCL8, GRM1, PYY, EDNRA and GRK5 mRNA were statistically different (all at P<0.05).The top six miRNAs which might be associated with hub genes were miR-15abc, miR-214, miR-23abc, miR-129-5p, miR-132 and miR-24. Conclusions:The 1 μmol/L glucocorticoid can negatively regulate the proliferation of HLE-B3 cells. SST, CXCL8, GRM1, PYY, EDNRA and GRK5 may be hub genes and miR-15abc, miR-214, miR-23abc, miR-129-5p, miR-132, miR-24 are most likely to relate to them.

Impact of air pollution on cardiovascular d is eases has been established. As the main source of city air pollution, particulat e matter has been demonstrated an independent correlation with incidence and mor tality of cardiovascular diseases. The mechanisms are not clear. Several plausib le mechanistic pathways have been described, including inflammation induced by o xidative stress, the followed enhanced coagulation/thrombosis resulted in instab ility of atherosclerosis, the promotion of ischemic heart diseases and imbalance of autonomic nerve tone resulted in the occurrence of arrhythmia. The article p rovides a review of the mechanisms on air pollution and cardiovascular diseases and suggestions for further research.

AIM: To compare the evaluations for the structure and function of the hypertrophic hearts induced by volume overload or pressure overload in rats. METHODS: Volume overload-induced cardiac hypertrophy was established by abdominal aortacaval fistula (ACF) and pressure overload-induced cardiac hypertrophy was developed by constriction of aorta (CA). The cardiac structure and function were analyzed by echocardiography, hemodynamic determination, heart weight measurement and histological examination. RESULTS: Heart weight of rats in all the operated groups was increased compared to the sham-operated groups. In 1-week ACF group, the internal diameter (0.67?0.03)cm vs (0.60?0.02)cm, P

Immunological rejection is the major barrier to successful transplantation.The immune response to an allograft is an ongoing dialogue between the innate and adaptive immune system that will lead to the rejection of allograft.Activation of elements of the innate immune system,triggered as a consequence of tissue injury sustained during cell isolation or organ retrieval and ischemia reperfusion,will initiate and amplify the adaptive response.Identifying the molecular pathways that trigger tissue injury,signal transduction and rejection facilitates the identification of targets for the development of immunosuppressants.
