ABSTRACT
OBJECTIVES@#Coronavirus disease 2019 (COVID-19) is an acute respiratory infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-CoV-2 can damage the myocardium directly, or activate the immune system, trigger a cytokine storm, and cause inflammatory cells to infiltrate the myocardial tissue and damage the myocardium. This study is based on the sequencing data to analyze the changes in gene expression of cardiomyocytes and macrophages after SARS-CoV-2 infection, and explore the potential effects of SARS-CoV-2 on the heart and immune system.@*METHODS@#The public data set GSE151879 was retrieved. The online software Network Analyst was used to preprocess the data, and the differentially expressed genes (DEGs) [log@*RESULTS@#After data standardization, the data quality was excellent and it can ensure reliable results. Myocardial cell infection with SARS-CoV-2 and gene expression spectrum were changed significantly, including a total of 484 DEGs in adult cardiomyoblasts, a total of 667 DEGs in macrophages, and a total of 1 483 DEGs in human embryo source of cardiomyopathy. The Stum, mechanosensory transduction mediator homolog (STUM), dehydrogenase/reductase 9 (DHRS9), calcium/calmodulin dependent protein kinase II beta (CAMK2B), claudin 1(CLDN1), C-C motif chemokine ligand 2 (CCL2), TNFAIP3 interacting protein 3 (TNIP3), G protein-coupled receptor 84 (GPR84), and C-X-C motif chemokine ligand 1 (CXCL1) were identical in expression patterns in 3 types of cells. The protein-protein interaction suggested that CAMK2B proteins may play a key role in the antiviral process in 3 types of cells; and silicon dioxide (SiO@*CONCLUSIONS@#CAMK2B, CLDN1, CCL2, and DHRS9 genes play important roles in the immune response of cardiomyocytes against SARS-CoV-2.

Objective:To observe the clinical curative effect of compound glycyrrhizin tablets and tacrolimus ointmenta combined with photon therapy on hormone dependence facial dermatitis and the safety.Methods:80 cases were randomly divided into two groups: treatment group and control group, 40 each; compound glycyrrhizin tablets and tacrolimus ointmenta were administrated to all the cases in both groups while photon therapy was added to cases in treatment group; a comparative study was made to observe the clinical effect 4 weeks after treatment between the two groups.Results:Four weeks after treatment, the effective rate was 86.67% in treatment group and 63.33% in control group, the difference was of statistical significance ( χ2=4.36, P<0.05); the total scores of symptoms and signs decreased obviously in both groups while the difference between the groups was of statistical significance ( t=3.10, P<0.05); topical medication led to drug adverse reaction in 4 cases in treatment group and 3 cases in control group with the manifestation of tolerable aggravated facial erythema and twinge while the adverse reaction disappeared gradually with the drug application keeping on for about 1 week. Conclusions:Compound glycyrrhizin tablets and tacrolimus ointmenta combined with photon therapy is of definite curative effect on hormone dependence facial dermatitis with good safety.
