Objective: To analyse the expression of differential mRNA in the plasma exosomes in patients with latent tuberculosis infection (LTBI) and active tuberculosis (ATB) using high-throughput sequencing, so as to provide insights into differential diagnosis of LTBI and ATB. Methods: The plasma samples were collected from the patients treated at The Affiliated Hospital of Hangzhou Normal University, including 16 cases of LTBI and 21 cases of ATB. The exosomes were extracted by Invitrogen extracellular extracts purification kit, and the size and morphology of exosomes were observed by transmission electron microscope (TEM). The exosomes were identified by Western blotting. Total RNA was extracted from plasma exosomes using high-throughput sequencing, differential expression mRNA was identified, and gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed. Two differential mRNAs with the highest differential expression fold were selected, and five patients with ATB and three patients with LTBI were recruited for verification using real-time quantitative PCR. Results: The sequencing results of plasma exosomes showed that compared with ATB patients, 2 875 differentially expressed mRNAs were detected in exosomes of LTBI patients, of which 1 002 mRNAs were up-regulated and 1 873 mRNAs were down-regulated. The most significant differentially expressed downregulated and upregulated mRNA were M6PR and RGPD5, respectively. GO analysis and KEGG pathway analysis showed that differential mRNAs were enriched in protein serine kinase activity, rRNA binding molecular function, human cytomegalovirus infection, pancreatic cancer, endometrial cancer, insulin signaling pathway and FoxO signaling pathway. The real-time quantitative PCR showed that the expression of differential mRNA was consistent with sequencing. Compared with ATB patients, the relative expression level of M6PR in plasma exosomes in LTBI patients (0.954±0.212) was downregulated compared with that of ATB patients (2.168±0.226), while the relative expression level of RGPD5 (2.126±0.200) was upregulated compared with that of ATB patients (0.588±0.129) (both P<0.05). Conclusions There is a difference in mRNA expression of plasma exosomes between patients with LTBI and ATB. M6PR and RGPD5 may become markers for distinguishing plasma exosomes between LTBI and ATB.

Objective:To evaluate the value of the ratio of tricuspid annular plane systolic excursion to pulmonary artery systolic pressure (TAPSE/PASP) in evaluating right ventricular function of patients with hypertrophic cardiomyopathy (HCM) and heart failure with preserved ejection fraction (HFpEF).Methods:A total of 74 patients with HCM and HFpEF and 22 healthy individuals who visited the First Affiliated Hospital of Zhengzhou University from January 2021 to January 2023 were included in this study. The HCM patients with HFpEF were divided into three groups based on the tertiles of the TAPSE/PASP (low group: <0.280 0 mm/mmHg; middle group: 0.280 0-0.476 2 mm/mmHg; high group: >0.476 2 mm/mmHg). Conventional echocardiographic parameters were collected, and two-dimensional speckle tracking technology was used to obtain right ventricular strain parameters. The differences in parameters among the groups were compared, and the correlations between TAPSE/PASP and clinical parameters and right ventricular function parameters were analyzed.Results:The results of difference analysis showed that there were significant differences in 6-minute walking test, New York Heart Association grade (NYHA grade), incidence of atrial fibrillation, left atrial area (LAA), left ventricular global longitudinal strain (LVGLS), TAPSE, PASP, right ventricular fractional area change (RVFAC), right ventricular global longitudinal strain (RVGLS), right ventricular free wall strain (RVFWST) and cardiac magnetic resonance right ventricular ejection fraction (CMR-RVEF) among the three groups. The results of correlation analysis and multiple linear regression analysis showed that the TAPSE/PASP was positively correlated with 6-minute walking distance, RVFAC, tricuspid annulus peak systolic velocity (RV s′), and CMR-RVEF ( r=0.449, 0.284, 0.358, 0.577; all P<0.05). It was negatively correlated with N-terminal pro-brain natriuretic peptide (NT-proBNP), NYHA grade, LAA, mitral early diastolic peak velocity / mitral annulus early diastolic peak velocity (LV E/e′), LVGLS, RVGLS, RVFWST and tricuspid early diastolic peak velocity / tricuspid annulus early diastolic peak velocity (RV E/e′) (r/ rs=-0.336, -0.349, -0.468, -0.452, -0.444, -0.339, -0.405, -0.320; all P<0.05). The LAA and CMR-RVEF correlated independently with TAPSE/PASP(all P<0.05). Conclusions:The TAPSE/PASP can provide an early, simple, rapid, and convenient evaluation of right ventricular function in patients with HCM and HFpEF, so as to guide clinical treatment and monitoring disease progression.
