Objective To explore working of concentration of PDL used in primary culture of rat hippocampal neurons.Methods 3 pregnant wistar rats were executed by cervical dislocation, the embryos were taken out and the hippocampal tissue was dissected quickly.Then the tissue was digested by trypsin and planted into dishes with proper concentration(300000/3.5cm vessle) which were coated by different PDL solution in different concentration (0.01,0.05,0.1,0.25,0.5,0.75,1,2 mg/mL).The state of the cultured neurons was observed to determine the most suitable concentration of PDL solution in coating dishes.Neurons activity was observed by CCK-8 Kit.Results Most neurons had adhered in 4 h.Protrusion of neurons began to grow in 1 d.The connection between neurons appeared in 4 d.Neurons matured and the network-connection was set up in 7 d.The best working concentration of PDL is between 0.25 and 0.75 mg/mL, neurons grew well and activity was optimum during this concentration.Conclusion The working concentration of PDL is important for the hippocampal neuron culture and this work is worth being applied.

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

Objective:To study the effect of sublingual immunotherapy on children with mite allergic rhinitis.Methods:Four hundred and ninety patients with mite allergic rhinitis have been recruited by Beijing Children′s Hospital from March 2014 to September 2019 and divided into 4 groups of young children group, different treatment duration group, individualized dose adjustment group and multiple allergy evaluation group, the clinical scores of total nasal symptoms score (TNSS), visual analogue scale scores (VAS) and total medication score were recorded at the first visit, 12 months, 24 months and 36 months after treatment, and the combined symptom and medication score(CSMS) score was calculated.Results:A total of 374 patients (76.32%) completed this study.Among them, the CSMS(2.20±1.61, 2.50±1.78), TNSS(2.80±2.32, 3.60±2.71) and VAS(3.50±1.16, 3.90±1.43) in ≤3-year-old group and children over 3-year-old group of young children set after use of 12 months were significantly lower than the score at the first time of diagnosis (respectively CSMS: 4.50±1.44, 5.30±1.32; TNSS: 6.20±1.89, 7.50±2.19; VAS: 5.40±2.33, 5.90±1.61). In addition, in the duration and efficacy set, the patients who completed the immunotherapy for 36 months can only be observed in the 3-year group, the scores were TNSS(0.90±0.97), VAS (1.30±1.19), CSMS (1.70±1.28); the scores of patients who completed the immunotherapy for 24 months in 2-year group and 3-year group were TNSS (2.10±0.95, 2.00±0.97), VAS (3.00±1.56, 3.10±1.68) and CSMS (3.10±1.15, 2.90±1.19) and the patients who completed 12-month immunotherapy were scored in 1-year group, 2-year group and 3-year group with TNSS(3.20±1.27, 3.10±1.41, 3.20±1.41), VAS(4.50±2.11, 4.70± 2.19, 4.50±2.17) and CSMS(4.20±1.39, 3.70±1.32, 4.10±1.39) respectively; patients with poor efficacy in sublingual immunotherapy achieved a score similar to the control group after 6 months of dose adjustment (equals to 12 months after treatment), that were CSMS(2.90±1.56, 2.90±1.88, 2.40±1.69), TNSS(4.70±2.98, 3.90±2.77, 3.80±2.45) and VAS(4.20±1.29, 4.50±1.65, 4.20±1.14) of 4 drops group, 5 drops group and control group; sublingual immunotherapy for patients with multiple allergens for 2 years finally achieved similar efficacy to patients with single allergen, with CSMS (2.30±0.50, 2.10±1.01, 1.90±1.01), TNSS (3.50±2.62, 3.70±2.62, 3.20±2.82) and VAS (4.50±1.00, 4.10±1.57, 3.80±1.54) in single allergen group, combined with 1-2 allergens group and combined with 3+ allergens group.Conclusions:Sublingual immunotherapy plays a corresponding role in the treatment of low-age children, multiple allergy children, and some children get better after dose adjustment.
