Objective To evalute the efficacy and safety of primary percutaneous coronary intervention (PCI) therapy and facilitated PCI therapy (thrombolysis plus PCI) for acute myocardial infarction (AMI). Methods Sixty four patients with ST elevation myocardial infarction (STEMI) were divided randomly into two groups including the facilitated PCI group and the primary PCI group. The patency rate of infarct-related artery (IRA) before intervention, the incidence of bleeding complications and acute ischemic events during hospitalization as well as the left ventricular ejection fraction (LVEF) measured by echocardiography before discharge were compared. The thrombolysis in myocardial infarction (TIMI) flow grade (TFG), TIMI myocardial perfusion grade (TMPG) and angiographic perfusion score (APS) in all patients were measured before and after PCI and the extent of ST segment elevation resolution was analyzed 90 minutes after reperfusion therapy. The relationship between APS and percentage of complete ST resolution was analysed by linear regression. Results The IRA patency rate and TMPG in the faciliated PCI group were significantly higher than that in the primary PCI group before PCI (P

Objective: To understand cognitive behavioral responses of college students in Guangxi at the early stage of COVID-19 regarding, and to provide a basis for schools and government to formulate relevant strategies and measures. Methods: An anonymous questionnaire survey was conducted among 69 783 students recruited online from 28 colleges and universities in Guangxi Province, regarding psychological response under public health emergencies. Results: Significant associated were found between the total score of COVID-19 knowledge score and factors scores of optimism, fear, avoidance, help and combat in cognitive behavioral response (r=0.15, -0.01, -0.06, -0.03, 0.28, P<0.05). Gender factors had an impact on all the five factors (Z=-13.67, -2.05, -13.31, -7.15, -24.34, P<0.05). Students with higher education levels and medical students had higher score in optimism and lower score in avoidance.Students with limited activities (β=0.38, 0.38, 0.42, P<0.05) and living in a community with infected cases score higher in factor including fear,escape and turning for help (β=0.14, 0.06, 0.15,P<0.05).optimism was negatively associated with fear among students living in a community with infected cases(β=-0.10,P<0.05). Conclusion Relevant departments need to strengthen science popularization and education, further improve students’ awareness of the epidemic, take scientific prevention and control measures, guide positive cognition, shape positive behavior, strengthen mental health education, and make preparations for the orderly resumption of school after the epidemic.

Through literature research, this paper analyzed the research progress of medical service project cost accounting based on cost equivalent method. According to the calculation mode of cost equivalent value, this method could be divided into two types, namely, equivalent coefficient method and point method. This paper classified and summarized the application status of cost equivalent method in the cost accounting of medical service projects, analyzed the advantages of cost equivalent method, such as being able to consider a variety of cost drivers, concise accounting process and strong operability, discussed the existing problems of this method, and put forward suggestions for further deepening the application of cost equivalent method and strengthening hospital cost accounting, such as strengthening the summary and case publicity of cost equivalent method, reasonably combining and applying various methods, and scientifically and reasonably developing hospital cost accounting information construction, so as to help build a scientific and accurate cost accounting system for medical service project.

Hepatocellular carcinoma (HCC), which makes up the majority of liver cancer, is induced by the infection of hepatitis B/C virus. Biomarkers are needed to facilitate the early detection of HCC, which is often diagnosed too late for effective therapy. The tRNA-derived small RNAs (tsRNAs) play vital roles in tumorigenesis and are stable in circulation. However, the diagnostic values and biological functions of circulating tsRNAs, especially for HCC, are still unknown. In this study, we first utilized RNA sequencing followed by quantitative reverse-transcription PCR to analyze tsRNA signatures in HCC serum. We identified tRF-Gln-TTG-006, which was remarkably upregulated in HCC serum (training cohort: 24 HCC patients vs. 24 healthy controls). In the validation stage, we found that tRF-Gln-TTG-006 signature could distinguish HCC cases from healthy subjects with high sensitivity (80.4%) and specificity (79.4%) even in the early stage (Stage I: sensitivity, 79.0%; specificity, 74.8%; 155 healthy controls vs. 153 HCC patients from two cohorts). Moreover, in vitro studies indicated that circulating tRF-Gln-TTG-006 was released from tumor cells, and its biological function was predicted by bioinformatics assay and validated by colony formation and apoptosis assays. In summary, our study demonstrated that serum tsRNA signature may serve as a novel biomarker of HCC.
