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.

Epidemiological characteristics of carbapenem-resistant Klebsiella pneumoniae infection in adult inpatients / 公共卫生与预防医学

Objective To analyze the epidemiological characteristics of carbapenem-resistant Klebsiella pneumoniae (CRKP) in adult inpatients, and to provide a theoretical basis for the diagnosis and treatment of CRKP. Methods A total of 753 hospitalized patients with Klebsiella pneumoniae (KPN) infection in our hospital from 2017 to 2021 were selected as the investigation subjects. According to the sensitivity to carbapenem drugs, the patients were divided into carbapenem sensitive Klebsiella pneumoniae (CSKP) group (n=638) and CRKP group (n=115). The age, gender, department distribution, underlying diseases, length of hospital stay, use of antibiotics and other clinical data of all subjects were analyzed by self-made survey scale of our hospital. Univariate analysis and logistic regression analysis were used to analyze the risk factors of CRKP nosocomial infection in adult inpatients. Results Among of 753 KPN patients, 115 cases (15.27%) were detected with CRKP, including 87 males and 28 females. The detection rate of CRKP in different age groups was significantly different (P60 years was significantly higher than that in the age group of 41-60 years, 21-40 years, and 16-20 years (P2 value =0.725, P>0.05). CRKP strains were mainly isolated from oral and maxillofacial surgery (19.13%), infection department (15.65%), geriatric department (15.65%), and ICU (14.78%). The detection rate of CRKP in different pathogenic bacteria samples was different, including sputum (19.40%), urine (15.43%) and blood (12.58%), with statistically significant difference (P<0.05) The respiratory tract sputum specimens were all expectoration. There were significant differences in age, gender, use of carbapenems ≥7 days, invasive procedures, use of antibiotics ≥2 kinds, use of antibiotics ≥14 days, and use of enzyme inhibitors ≥7 days between the CSKP group and the CRKP group (P<0.05). Antimicrobial application time ≥14 days (OR=5.412), invasive operation (OR=6.431), and carbapenem use ≥7 days (OR=5.417) were the risk factors for CRKP nosocomial infection in adult inpatients (P<0.05). Conclusion Nosocomial infection of CRKP occurs mostly in elderly ICU patients. Intervention measures should be given to adult inpatients who have used antibiotics for ≥14 days, invasive procedures, and carbapenem antibiotics for ≥7 days, which can reduce the risk of CRKP infection in inpatients.

Objective To investigate the expression levels of serum vascular endothelial growth factor (VEGF), lactate dehydrogenase (LDH), sugar chain antigen-125 (CA125), and β2-microglobulin (β2-MG) in peripheral blood of patients with diffuse large B-cell lymphoma (DLBCL) and their clinical significances. Methods Thirty cases of DLBCL diagnosed by pathology in Fenyang Hospital of Shanxi Province and Shanxi Dayi Hospital from December 2011 to June 2013, 20 cases of healthy individuals as normal control group were enrolled. The levels of serum VEGF, CA125 and β2-MG in peripheral blood were detected by enzyme-linked immunosorbent assay (ELISA). Serum levels of LDH were detected by the rate method for measuring. Results The expression levels of VEGF, LDH, CA125 and β2-MG in DLBCL patients were higher than those in the healthy control group [(368±194) vs. (156±48) pg/ml, t=5.718, P=0.000;(487±252) vs. (177±32) U/L, t= 6.658, P= 0.000; (58 ±16) vs. (19 ±10) U/ml, t= 9.701, P= 0.000; (3.1 ±1.5) vs. (1.6 ±0.3 ) mg/L, t=5.612, P=0.000]. The expression levels of serum VEGF and LDH in DLBCL patients with stage Ⅲ-Ⅳ were significantly higher than those in patients with stage Ⅰ-Ⅱ [(506±165) vs. (275±154) pg/ml, t= 3.896, P=0.000; (886 ±433) vs. (220 ±86) U/L, t= 5.244, P= 0.000]. The expression levels of VEGF and LDH in DLBCL patients with bone marrow infiltration were higher than those in patients without bone marrow infiltration [(505±201) vs. (299±152) pg/ml, t= 3.148, P= 0.004; (798±463) vs. (331±166) U/L, t= 3.113, P=0.005]. There were no significant differences in the expression levels of VEGF and LDH between patients with A symptoms and B symptoms (all P>0.05). The serum levels of CA125 and β2-MG in the observation group had not relationship with clinical stage, the presence of A or B symptoms and the presence of bone marrow infiltration (all P> 0.05). The high expression of VEGF had correlation with the high expression of LDH in the observation group (r=0.458, P<0.05). Conclusions The expression levels of VEGF, LDH, CA125 andβ2-MG in DLBCL patients before treatment are high, and the high expression levels of VEGF and LDH are closely related to the clinical stage, disease progression and invasion. Combined detection of VEGF and LDH may be a useful predictor of bone marrow involvement in patients with DLBCL.

Phylogenetic analysis of brine shrimp (Artemia) in China using DNA barcoding / 基因组蛋白质组与生物信息学报·英文版

DNA barcoding is a powerful approach for characterizing species of organisms, especially those with almost identical morphological features, thereby helping to to establish phylogenetic relationships and reveal evolutionary histories. In this study, we chose a 648-bp segment of the mitochondrial gene, cytochrome c oxidase subunit 1 (COI), as a standard barcode region to establish phylogenetic relationships among brine shrimp (Artemia) species from major habitats around the world and further focused on the biodiversity of Artemia species in China, especially in the Tibetan Plateau. Samples from five major salt lakes of the Tibetan Plateau located at altitudes over 4,000 m showed clear differences from other Artemia populations in China. We also observed two consistent amino acid changes, 153A/V and 183L/F, in the COI gene between the high and low altitude species in China. Moreover, indels in the COI sequence were identified in cyst and adult samples unique to the Co Qen population from the Tibetan Plateau, demonstrating the need for additional investigations of the mitochondrial genome among Tibetan Artemia populations.
