Objective:To express NY-ESO-1 epitopes using circular RNA (circRNA) and construct circRNA cancer vaccines using a novel lipid-like material C1, and to evaluate the transfection efficiency and T cell activation potential at cellular level.Methods:In vitro transcription was used to synthesize mRNA and circRNA expressing EGFP and NY-ESO-1 epitopes. Then, they were transfected into COS7 cells and the expression of target proteins were detected in vitro. Lipid-like material C1 and commercial transfection agent TransIT-mRNA were used as delivery systems for mRNA NY-ESO-1 and circRNA NY-ESO-1, and their delivery efficiency was compared. Results:The expression of EGFP was observed under fluorescence microscopy after transfection of mRNA EGFP and circRNA EGFP into COS7 cells for 24 h. The secretion of IFN-γ by T cell receptor-engineered T (TCR-T) cells targeting NY-ESO-1/HLA-A2 was stimulated by COS7-A*02: 01 cells transfected with mRNA NY-ESO-1 and circRNA NY-ESO-1. Compared with mRNA NY-ESO-1, circRNA NY-ESO-1 was able to express the target antigen and stimulate the target cells to release IFN-γ more persistently. The delivery efficiency of C1 material was better than that of commercial transfection reagents when COS7 cells were transfected in vitro. Conclusions:Compared with the linear mRNA, transfection of COS7-A*02: 01 cells with circRNA can lead to more efficient and durable activation of T cells, suggesting that it could be a more suitable candidate for clinical treatment of tumors in the future. The lipid-like material C1 can effectively deliver linear mRNA and circular RNA molecules. This study provides reference for further research on circRNA tumor vaccines.

Objectives:To analyze the disease burden and changing trends of non-rheumatic valvular heart disease(NRVHD)from 1990 to 2019 in China. Methods:Based on the Global Burden of Disease 2019 database,we collected data related to NRVHD in China from 1990 to 2019,analyzed the crude incidence rate,crude prevalence rate,crude disability-adjusted life year(DALY),and age-scaled rate of NRVHD during this period,and analyzed the corresponding trends.The grey prediction model GM(1,1)was used to predict the disease burden of NRVHD in China from 2020 to 2029. Results:The crude incidence,crude prevalence,and crude DALY rates of NRVHD increased in China from 7.87/100 000,123.21/100 000,and 9.83/100 000 in 1990 to 22.85/100 000,374.16/100 000,and 11.95/100 000 in 2019;the age-standardized incidence rate and the age-standardized prevalence rate increased from 9.22/100 000 and 169.04/100 000 in 1990 to 15.30/100000 and 262.85/100 000 in 2019 respectively,with females being higher than males;the age-standardized DALY rate declined from 13.43/100 000 in 1990 to 9.07/100 000 in 2019,with females being higher than males.Joinpoint regression model analysis showed an increasing trend in the age-standardized incidence rate and age-standardized prevalence rate,and a decreasing trend in the age-standardized DALY rate(annual average percentage change[AAPC]values of 1.86%,1.72%and-1.66%,respectively),trend of change was statistically significant(all P<0.05).The burden of disease for all age groups from 1990 to 2019 showed an overall increasing trend,and the crude incidence rate,crude prevalence rate and crude DALY rate all increased with age,and the elderly group over 60 years old was the main group of disease burden.The results of the grey prediction model showed that by 2029,the age-standardized incidence rate and age-standardized prevalence rate would increase to 18.51/100 000 and 303.26/100 000,respectively,and the age-standardized DALY rate would decrease to 7.42/100 000. Conclusions:From 1990 to 2019,the age-standardized incidence rate and age-standardized prevalence rate of NRVHD in China showed an increasing trend,and the age-standardized DALY rate all showed a decreasing trend.The disease burden of NRVHD in China remains high.Women and the senior population are the main target groups needing special attention in China,and more targeted prevention and treatment strategies are needed for high-risk population.

Klebsiella pneumoniae is one of the common pathogens causing hospital-acquired infection. With the wide use of carbapenem in recent years, carbapenem-resistant Klebsiella pneumoniae (CRKP) has emerged around the world. Carbapenemase production is the main cause of resistance to carbapenem antibiotics in Klebsiella pneumoniae. More than 70% of Klebsiella pneumoniae strains produce carbapenemase. Ceftazidime/avibactam (CAZ/AVI) can effectively treat CRKP infection, especially those caused by CRKP that can produce Klebsiella pneumoniae carbapenemase (KPC) or oxaclillinase (OXA)-48. However, it has been reported that CAZ/AVI-resistant CRKP strains have emerged. In this paper, the epidemiology, risk factors, resistance mechanism and treatment of CAZ/AVI-resistant CRKP were summarized to provide reference for clinical treatment.
