Objective: To understand the trends and associated factors of tuberculosis knowledge and behavior among freshmen from Jiangsu Province, 2019 to 2022, so as to provide theoretical support for the popularization of tuberculosis knowledge and the prevention and control of tuberculosis in universities. Methods: From 2019 to 2022, a total of 33 944 freshmen from 20 universities in Jiangsu Province were selected by stratified random sampling, and tuberculosis knowledge and behavior were surveyed online using a selfdesigned questionnaire. Oneway variance trend test and multiple linear regression analysis were used to analyze the trend of knowledge and behavior levels, and a multiple linear regression model was used to analyze the influencing factors. Results: The overall awareness rate of tuberculosis among freshmen from Jiangsu Province was 90.6%, and the overall awareness rates from 2019 to 2022 were 88.4%, 90.4%, 91.7%, and 91.8%, respectively. The overall behavioral accuracy rate was 92.3%, with the annual rates from 2019 to 2022 being 91.8%, 92.3%, 92.7%, and 92.4%, respectively. Both the awareness rate and accuracy behavior rate increased annually (F=216.67, 11.75, P<0.01). The multiple linear regression analysis showed that school type, ethnicity, fathers educational level, mothers educational level, mothers occupation, family per capita monthly income, and living arrangement in high school affected both personal knowledge awareness rate and personal behavioral accuracy rate (β=-0.047-0.035, P<0.01), while region, gender, family residence, and being an only child only affected behavioral accuracy rate (β=-0.003-0.032, P<0.05). Conclusions The tuberculosis knowledge and behavior levels of freshmen from Jiangsu Province have been increasing by year. Targeted health education should be carried out based on the relevant influencing factors to further enhance the tuberculosis prevention and control literacy.

Circular RNA(circRNA)is a novel class of endogenous non-coding RNA with complex biological func-tions,participating in various physiological and pathological processes.Due to their relatively stable stucture and tissue-specific and temporal expression patterns,circRNA have become a recent focus of biomedical research.Heart failure(HF)is characterized by impaired ventricular filling and/or ejection function caused by primary myocardial injury and car-diac overload,leading to the inability of the heart to meet the metabolic demands of the body's tissues.It is the end stage of numerous cardiac diseases.Studies have found that circRNA may play a crucial regulatory role in the progression of HF,particularly in cardiomyocyte hypertrophy,cardiomyocyte apoptosis,autophagy and myocardial fibrosis.This review summarizes the formation,classification,functional forms,and roles in HF of circRNA,aiming to provide new insights for the prevention and treatment of HF.

Objective: To understand the changing trends and related factors of knowledge, attitude and practice (KAP) regarding the three major infectious diseases (acquired immunodeficiency syndrome, tuberculosis, hepatitis B) among freshmen in Jiangsu from 2019 to 2022, so as to provide a reference basis for the health education of infectious diseases in schools. Methods: From 2019 to 2022, a total of 33 944 freshmen from 20 universities in Jiangsu Province were randomly selected for four consecutive years to investigate their KAP levels online through self designed questionnaires on three major infectious diseases. The multiple linear regression model was used to analyze the changing trends of students KAP levels of the three major infectious diseases, and to explore the influencing factors of KAP. Results: From 2019 to 2022, the knowledge scores(18.0±3.1,18.4±3.2,18.7±3.2,18.8±3.2), related to the three major infectious diseases showed an upward trend ( F=436.50, P <0.01), and the positive attitude reporting rates were 81.77%, 81.46%, 82.68% and 81.74%, respectively. The reporting rates of positive practice were 80.11%, 79.25%, 79.08 % and 79.04%, respectively. Multiple linear regression showed that school type, parental education level, mother s occupation, average income per person in family and living arrangements during high school all had an impact on the knowledge ( β = -1.510 -0.559), attitudes ( β =-0.043-0.065) and practice ( β =-0.028-0.027) of the three major infectious diseases ( P < 0.05 ). The family residence areas only affected the reporting rate of positive attitude scores ( β =0.002-0.065), and whether only children or not affected the reporting rate of positive practice scores ( β =0.009)( P <0.05). The knowledge score showed an upward trend ( β= 0.297, P <0.01), the positive attitude reporting rate showed no statistically significant change ( β=0.001, P =0.22), and the positive practice reporting rate showed a downward trend ( β=-0.005, P <0.01). Conclusions Freshman in Jiangsu Province from 2019 to 2022 have shown a separation in KAP scores regarding the three major infectious diseases. Targeted measures should be taken to improve their health practice level.

Objective Stereotactic body radiotherapy(SBRT)and radiofrequency ablation(RFA)are primary treatments for hepatocellular carcinoma(HCC)at present.However,the effect of these treatments in clinical trails are rather controversial.The purpose of this paper is to conduct a meta-analysis on the clinical effect and related complications of SBRT and RFA for HCC.Methods A computerized retrieval of academic papers concerning the treatment effect of SBRT and RFA for HCC from the databases of PubMed,Embase,Cochrane Library,Scopus,Web of Science,CBM,CNKI,Wanfang database,VIP was conducted.The retrieval time period was from the establishment of the database to June 2022.Stata14.0 software was used to make meta-analysis.Results A total of 14 retrospective studies including 6 806 patients were included in this analysis.The results of combined hazard ratio(HR)based on overall survival(OS)showed that the OS rate of SBRT was lower than that of RFA(HR=1.25,95％CI=1.10-1.43,12=0％,P=0.000 9),while the results of combined HR of local control(LC)rate indicated that SBRT had a better therapeutic effect(HR=0.61,95％CI=0.47-0.78,I2=0％,P=0.000 1).Subgroup analysis revealed that the combined HR of LC rate favored the performance of SBRT for patients with tumor diameter larger than 2 cm(HR=2.64,95％CI=1.56-4.48,I=0％,P=0.000 3).No statistically significant difference in the incidence of late serious adverse reactions existed between SBRTgroup and RFA group(OR=1.01,95％CI=0.59-1.73,I2=30％,P=0.97).Conclusion SBRT is superior to RFA in controlling local HCC lesions,especially in patients whose tumor diameter is larger than 2 cm,although it does not show certain advantages in the survival benefit.(J Intervent Radiol,2023,32:1233-1241)
