Objective:To evaluate the correlation and consistency between quantitative coronary flow fraction (QFR) and cardiac magnetic resonance imaging (CMR) in assessing myocardial ischemia in patients with coronary heart disease (CAD).Methods:A retrospective analysis was conducted on the data of coronary heart disease patients who underwent load CMR examination and coronary angiography at the Beijing Anzhen Hospital, Capital Medical University from August 2017 to March 2022. CMR examination includes cardiac cine, load/rest myocardial perfusion imaging, and delayed enhancement sequence. According to the results of CMR examination, the patient′s left ventricular myocardial segments were divided into normal segment group and abnormal segment group (further divided into ischemic segment group and infarcted segment group). On the basis of coronary angiography, an artificial intelligence based platform (AngioPlus system) was applied to calculate the preoperative coronary artery QFR value of patients undergoing percutaneous coronary intervention treatment. Kappa test was used to evaluate the consistency of QFR and CMR in diagnosing abnormal myocardium; Mann Whitney U test was used to compare the differences in QFR between groups; The receiver operating characteristic (ROC) curve was used to evaluate the efficacy of QFR in diagnosing abnormal myocardium; Spearman correlation analysis was used to clarify the relationship between myocardial infarction area and QFR value of the supplying coronary artery in patients.Results:Among the 70 CAD patients enrolled, there were 60 males and 10 females, aged (54.1±11.1)years. At the vascular level, the consistency between QFR and CMR in diagnosing myocardial injury (including ischemia and infarction) is moderate (Kappa value=0.514). The sensitivity and specificity of detecting abnormal myocardial segments in CAD patients were 57% and 91%, respectively. The area under the curve (AUC) value of QFR predicting abnormal myocardium in CAD patients was 0.769, and the optimal cutoff value was QFR=0.865. At this time, the sensitivity and specificity of QFR predicting myocardial injury in CAD patients were 67.2% and 84.3%, respectively. The difference in vascular QFR between the normal segment group, ischemic segment group, and infarcted segment group was statistically significant ( P<0.001), with the infarcted segment group having significantly lower QFR values than the other two groups (all P<0.01). The range of myocardial infarction was negatively correlated with the QFR value of the supplying coronary artery ( r=-0.45, P<0.001). At the patient level, the consistency between QFR and CMR in diagnosing myocardial injury (including ischemia and infarction) was moderate (Kappa value=0.445), with a sensitivity of 74% and a specificity of 81% for diagnosing myocardial injury in CAD patients. Conclusions:Compared with CMR, QFR has better specificity in detecting myocardial injury in CAD patients. The QFR value of the infarcted segment group is significantly lower than that of the ischemic group and the normal group. The area of myocardial infarction is negatively correlated with the QFR value of the supplying coronary artery.

Objective: To investigate GATA3 expression and the regulatory mechanism of m6A modification in the re- sponse of alveolar epithelial cells to radiation, and to provide a new therapeutic target for radiation-induced lung injury based on its pathogenesis. Methods: Human lung epithelial cell line (A549) and mouse lung epithelial cell line (MLE-12) were exposed to X-ray irradiation with a single dose of 10 Gy (dose rate 1 Gy/min) and 6 Gy (dose rate 0.75 Gy/min), respect- ively. The expression of VIRMA gene (RNA methylase) was inhibited by lipofection of A549 cells and MLE-12 cells with shRNA-VIRMA plasmid and siRNA-VIRMA interfering fragment, respectively. Quantification of m6A RNA methylation was performed by colorimetry. Changes in the expression of mRNAs of VIRMA, GATA3, and epithelial-mesenchymal transition (EMT) markers in irradiated A549 and MLE-12 cells were determined by qRT-PCR. Changes in the expression of VIRMA,  GATA3,  and  EMT  marker  proteins  in  irradiated  A549  and  MLE-12  cells  were  determined  by  Western  blot. Results: Radiation up-regulated the expression of methylase VIRMA in A549 and MLE-12 cells, which in turn enhanced the m6A of total RNA and the expression of GATA3 gene and protein, resulting in EMT. Furthermore, in A549 and MLE-12 cells, interference of the VIRMA gene significantly reduced the expression of GATA3 gene and protein and the expression of EMT-related molecules. Conclusion　 Radiation induces m6A modification in alveolar epithelial cells, which up-regu- lates the expression of GATA3 gene and induces EMT, thus playing an important role in the process of radiation-induced lung injury.

Objective:To investigate the risk factors and their warning value for the occurrence of sepsis in patients with severe multiple trauma.Methods:A retrospective cohort study was conducted to analyze the clinical data of 92 patients with severe multiple trauma admitted to Yuyao People′s Hospital from July 2019 to October 2021. There were 71 males and 21 females, with the age range of 36-55 years [(45.5±13.6)years]. The injury severity score (ISS) was 20-29 points [(25.3±6.4)points]. The patients were divided into sepsis group ( n=32) and non-sepsis group ( n=60) according to whether sepsis occurred during hospitalization. Data were recorded for the two groups, including gender, age, basic diseases, cause of injury, number of injury sites, ISS, post-injury complications, and levels of aryl hydrocarbon receptor (AHR), C-reactive protein (CRP) and procalcitonin (PCT) at 1, 3 and 5 days after injury. The above data were analyzed to identify their correlation with the occurrence of sepsis in patients with severe multiple trauma by univariate analysis. The independent risk factors for sepsis in patients with severe multiple trauma were determined by multivariate Logistic regression analysis. The warning value of the single or combined risk factors for the occurrence of sepsis in patients with severe multiple trauma was evaluated by the receiver operating characteristic (ROC) curve and area under the curve (AUC). Results:By univariate analysis, it was demonstrated that the occurrence of sepsis was correlated with ISS, level of AHR at day 1 after injury, level of CRP at day 3 after injury and level of PCT at day 3 after injury ( P<0.05 or 0.01), but not with age, sex, basic diseases, level of AHR at 3, 5 days after injury, level of PCT at 1, 5 days after injury and level of CRP at 1, 5 days after injury (all P>0.05). By multivariate Logistic regression analysis, higher ISS ( OR=1.12, 95% CI 1.01, 1.24, P<0.05), level of AHR at day 1 after injury ( OR=1.30, 95% CI 1.10, 1.52, P<0.01) and level of PCT at day 3 after injury ( OR=1.81, 95% CI 1.08, 3.03, P<0.05) were found to be strongly correlated with the occurrence of sepsis. ROC curve analysis showed that higher ISS (AUC=0.69, 95% CI 0.57, 0.76) and level of AHR at day 1 after injury (AUC=0.79, 95% CI 0.68, 0.90) had warning value for the occurrence of sepsis, and the warning efficiency of combined panel was much better (AUC=0.86, 95% CI 0.77, 0.95). Conclusions:Higher ISS, level of AHR at day 1 after injury and level of PCT at day 3 after injury are independent risk factors for the occurrence of sepsis in patients with severe multiple trauma. ISS, AHR and combination of both exhibit good warning value for the occurrence of sepsis in patients with severe multiple trauma.

Objective:To investigate the effect of liraglutide(LRG) on high glucose-induced oxidative stress injury in(H9c2) cardiomyocytes and its underlying mechanisms.Methods:A high glucose treatment was applied to H9c2 cells for 24 hours to establish an in vitro model of myocardial cell injury. Different concentrations of liraglutide(10, 100, 1000 nmol/L) were administered for intervention. Cell viability was evaluated using the CCK-8 assay, and changes in cell morphology were observed under an inverted microscope. After 24 hours of liraglutide(100 nmol/L) intervention following high glucose treatment, the levels of lactate dehydrogenase(LDH), superoxide dismutase(SOD), and malondialdehyde(MDA) in the cell supernatant were measured. RT-PCR and Western blotting were used to detect the mRNA and protein levels of silent information regulator factor 1(SIRT1) and forkhead box protein O1(FOXO1). Western blotting was also used to assess the acetylation level of FOXO1 protein. Small interfering RNA(siRNA) technology was employed to silence SIRT1 in H9c2 cells to confirm its role in the study. Results:Compared to the control group, the high glucose group showed decreased cell viability, cell structure damage, increased levels of LDH and MDA in the cell supernatant, decreased SOD levels, aggravated oxidative stress, decreased SIRT1 expression, and increased acetylation level of FOXO1(all P<0.05). Compared to the high glucose group, liraglutide intervention resulted in increased cell viability, improved cardiac cell morphology, reduced oxidative stress levels, increased SIRT1 expression, and decreased acetylation level of FOXO1(all P<0.05). When SIRT1 was downregulated, the protective effects of liraglutide were weakened(all P<0.05). Conclusions:Liraglutide has a protective effect against high glucose-induced oxidative stress injury in H9c2 cells, which may be associated with the upregulation of SIRT1 expression.
