Omicron BA.4/5 neutralization and cell-mediated immune responses in relation to baseline immune status and breakthrough infection among PLWH: A follow-up cohort study.

There is a paucity of data on hybrid immunity (vaccination plus breakthrough infection [BI]), especially cell-mediated responses to Omicron among immunosuppressed patients. We aim to investigate humoral and cellular responses to Omicron BA.4/5 among people living with HIV (PLWH) with/without BIs, the most prevalent variant of concern after the reopening of China. Based on our previous study, we enrolled 77 PLWH with baseline immune status of severe acute respiratory syndrome coronavirus 2 specific antibodies after inactivated vaccination. "Correlates of protection," including serological immunoassays, T cell phenotypes and memory B cells (MBC) were determined in PLWH without and with BI, together with 16 PLWH with reinfections. Higher inhibition rate of neutralizing antibodies (NAb) against BA.4/5 was elicited among PLWH with BI than those without. Omicron-reactive IL4+ CD8+ T cells were significantly elevated in PLWH experienced postvaccine infection contrasting with those did not. NAb towards wild type at baseline was associated with prolonged negative conversion time for PLWH whereas intermediate MBCs serve as protecting effectors. We uncovered that hybrid immunity intensified more protection on BA.4/5 than vaccination did. Strengthened surveillance on immunological parameters and timely clinical intervention on PLWH deficient in protection would reduce the severity and mortality in the context of coexistence with new Omicron subvariants.

Single-cell dissection of cellular and molecular features underlying mesenchymal stem cell therapy in ischemic acute kidney injury.

Mesenchymal stem cells (MSCs) exert beneficial therapeutic effects in acute kidney injury (AKI), while the detailed repair mechanism remains unclear. Herein, we probed the underlying mechanisms of MSC therapy in AKI by performing unbiased single-cell RNA sequencing in IRI model with/without MSC treatment. Our analyses uncovered the tubular epithelial cells (TECs) and immune cells transcriptomic diversity and highlighted a repair trajectory involving renal stem/progenitor cell differentiation. Our findings also suggested that profibrotic TECs expressing pro-fibrotic factors such as Zeb2 and Pdgfb promoted the recruitment of inflammatory monocytes and Th17 cells to injured kidney tissue, inducing TGF-ß1 secretion and renal fibrosis. Finally, in addition to activating the repair properties of renal progenitor/stem cells, we uncovered a role for MSC-derived miR-26a-5p in mediating the therapeutic effects of MSCs by inhibiting Zeb2 expression and suppressing pro-fibrotic TECs and its subsequent recruitment of immune cell subpopulations. These findings may help to optimize future AKI treatment strategies.

The effect of short-term remote ischemic preconditioning on endothelial function of patients with chronic kidney disease: A randomized pilot study.

AIM: Patients with chronic kidney disease (CKD) are more susceptible to endothelial dysfunction and cardiovascular disease (CV). Remote ischemic preconditioning (rIPC) has been proven efficient in improving endothelial function and lowering the risk of CV. However, the safety and effect of rIPC on endothelial function in patients with CKD have not been effectively assessed. METHODS: 45 patients with CKD (average estimated glomerular filtration rate: 48.4 mL/min/1.73 m2) were randomly allocated to either 7-day daily upper-arm rIPC (4 × 5 min 200 mmHg, interspaced by 5-min reperfusion) or control (4 × 5 min 60 mmHg, interspaced by 5-min reperfusion). Vascular endothelial function was assessed by natural log-transformed reactive hyperemia index (LnRHI) before and after a 7-day intervention. Arterial elasticity was assessed by augmentation index (AI). RESULTS: The results showed that LnRHI could be improved by rIPC treatment (Pre = 0.57 ± 0.04 vs. Post = 0.67 ± 0.04, p = .001) with no changes relative to control (Pre = 0.68 ± 0.06 vs. Post = 0.64 ± 0.05, p = .470). Compared with the control group, the improvement of LnRHI was greater after rIPC treatment (rIPC vs. Control: 0.10 ± 0.03 vs. -0.04 ± 0.06, between-group mean difference, -0.15 [95% CI, -0.27 to -0.02], p = .027), while there was no significant difference in the change of AI@75 bpm (p = .312) between the two groups. CONCLUSION: RIPC is safe and well tolerated in patients with CKD. This pilot study suggests that rIPC seems to have the potential therapeutic effect to improve endothelial function. Of note, further larger trials are still warranted to confirm the efficacy of rIPC in improving endothelial function in CKD patients.

The association between schizophrenia and white blood cells count: a bidirectional two-sample Mendelian randomization study.

BACKGROUND: Positive associations between the risk of schizophrenia and the level of white blood cells (WBC) count have been suggested by observational studies. However, the causality of this association is still unclear. METHODS: We used a group of bidirectional two-sample Mendelian randomization (MR) analyses to estimate the causal relationship between schizophrenia and WBC count traits (i.e., WBC count, lymphocyte count, neutrophil count, basophil count, eosinophil count, and monocyte count). The threshold of FDR-adjusted P < 0.05 was considered as showing potential evidence of a causal effect. Instrument variables were included based on the genome-wide significance threshold (P < 5 × 10- 8) and linkage disequilibrium (LD) clumping (r2 < 0.01). In total, 81, 95, 85, 87, 76, and 83 schizophrenia-related single nucleotide polymorphisms (SNPs) were used as genetic instruments from Psychiatric Genomics Consortium for six WBC count traits, respectively. And in reverse MR analysis, 458, 206, 408, 468, 473, and 390 variants extracted from six WBC count traits were utilized as genetic instruments, which were obtained from a recent large-scale Genome-Wide Association Study (GWAS). RESULTS: Genetically predicted schizophrenia was positively associated with the level of WBC count [odds ratio (OR) 1.017, 95% confidence interval (CI) 1.008-1.026; P = 7.53 × 10- 4], basophil count (OR 1.014, 95%CI 1.005-1.022; P = 0.002), eosinophil count (OR 1.021, 95%CI 1.011-1.031; P = 2.77 × 10- 4), monocyte count (OR 1.018, 95%CI 1.009-1.027; P = 4.60 × 10- 4), lymphocyte count (OR 1.021, 95%CI 1.012-1.030; P = 4.51 × 10- 5), and neutrophil count (OR 1.013, 95%CI 1.005-1.022; P = 0.004). WBC count traits are not associated with the risk of schizophrenia in our reverse MR results. CONCLUSION: Schizophrenia is associated with elevated levels of WBC count (i.e., higher WBC count, lymphocyte count, neutrophil count, basophil count, eosinophil count, and monocyte count).

Long-term trends of nasopharyngeal carcinoma mortality in China from 2006 to 2020 by region and sex: an age-period-cohort analysis.

BACKGROUND: China has a high mortality from nasopharyngeal carcinoma (NPC). The NPC mortality trends in China from 2006 to 2020 were described and analyzed to understand its epidemiological characteristics by region and sex and to explore age, period, and cohort effects. METHODS: This study utilized NPC mortality data from the China Health Statistical Yearbook. A joinpoint regression model was used to fit the standardized NPC mortality and age-specific mortality. The age-period-cohort model was applied to investigate age, period, and cohort effects on NPC mortality risk. RESULTS: The results showed that the NPC mortality rate in China has been declining steadily. From 2006 to 2020, the standardized NPC mortality rate in most age groups showed a significant downward trend. The annual percentage change was smaller in rural areas than in urban areas. The mortality risks of rural males and rural females from 2016 to 2020 were 1.139 times and 1.080 times those from 2011 to 2015, respectively. Both urban males born in 1984-1988 and rural males born in 1979-1983 exhibited an increasing trend in NPC mortality risk. CONCLUSIONS: Our study confirmed the effectiveness of NPC prevention and treatment strategies in China from 2006 to 2020. However, it underscored the urgent need for targeted interventions in rural areas to further reduce NPC mortality rates.

Survey of the Prosthogonimus spp. metacercariae infection in the second intermediate host dragonfly in Heilongjiang Province, China.

Prosthogonimiasis poses a threat to the reproductive system of poultry and wild birds, which are the definitive hosts of the parasite causing this disease. However, the parasite infection of the second intermediate host (dragonfly), the primary vector of this pathogen, is rarely reported. In this study, the prevalence of Prosthogonimus infection in dragonflies was investigated from June 2019 to October 2022 in Heilongjiang Province, northeast China. The species of metacercariae isolated from dragonfly were identified by morphological characteristics, molecular biology techniques, and animal infection experiments. The results showed that 11 species of dragonflies and one damselfly were identified and among six of the dragonflies infected by Prosthogonimus metacercariae, Sympetrum depressiusculum (28.53%) had the highest infection rate among all positive dragonflies, followed by Sympetrum vulgatum (27.86%) and Sympetrum frequens (20.99%), which are preferred hosts, and the total prevalence was 20.39% (2061/10,110) in Heilongjiang Province. Three species of Prosthogoniumus metacercariae were isolated, including Prosthogonimus cuneatus, Prosthogonimus pullucidus, and Prosthogonimus sp., among which P. cuneatus was the dominant species in dragonflies in Heilongjiang Province. This is the first report on the prevalence of Prosthogonimus in dragonflies in China, which provides baseline data for the control of prosthogonimiasis in Heilongjiang Province and a reference for the prevention of prosthogonimiasis in other areas of China.

Association of the malnutrition-inflammation score with physical function and functional disability in elderly patients with chronic kidney disease.

BACKGROUND AND OBJECTIVES: To describe nutritional status and inflammation of elderly patients with chronic kidney disease and to confirm the association between a Malnutrition-Inflammation Score and physical func-tion and functional disability. METHODS AND STUDY DESIGN: A total of 221 chronic kidney disease patients (aged ≥60 years) were included. A Malnutrition-Inflammation Score was used to assess malnutrition and inflammation. Physical function was assessed using the SF-12. Functional status was evaluated using basic activities of daily living and instrumental activities of daily living. RESULTS: Thirty percent of participants had a Malnutrition-Inflammation Score ≥6, which denoted poor nutritional status. Participants with a Malnutrition-Inflammation Score ≥6 had decreased concentration of hemoglobin, albumin, prealbumin, handgrip strength and walking speed and increased concentration of inflammatory markers, including CRP, IL-6 and fibrinogen. Physical function and physical component summary were lower and basic activities of daily living dependence and instrumental activities of daily living dependence were higher among patients with higher Malnutrition-Inflammation Score than those with a lower Malnutrition-Inflammation Score. The Malnutrition-Inflammation Score was an independent risk factor for physical function and instrumental activities of daily living dependence. CONCLUSIONS: The elderly chronic kidney disease patients with a high Malnutrition-Inflammation Score had a decreased physical function and an increased risk of functional instrumental activities of daily living dependence.

Different effects of pea protein on the properties and structures of starch gel at low and high solid concentrations.

In the context of starch-protein composite gels, the influence of protein on gel formation significantly shapes the textural attributes of starch gels, leading to distinct outcomes. This study aimed to evaluate how different ratios of pea protein (PP) affect the properties and structures of starch-protein composite gels at low (10 wt%) and high (40 wt%) solid concentrations. The addition of PP had opposite effects on the two gels. Compared to the pure starch gel, the low-concentration composite gel (LCG) with 20 % PP experienced a 48.90 ± 0.33 % reduction in hardness, and the storage modulus (G') decreased from 14,100 Pa to 5250 Pa, indicating a softening effect of PP on LCG. Conversely, the hardness of the high-concentration composite gel (HCG) with 20 % PP exhibited a 62.19 ± 0.03 % increase in hardness, and G' increased from 12,100 Pa to 41,700 Pa, highlighting the enhancing effect of PP on HCG. SEM and fluorescence microscopy images showed that PP induced uneven network sizes in LCG, while HCG with a PP content of 20 %, PP, together with starch, formed a three-dimensional network. This study provides valuable insights and guidance for the design and production of protein-enriched starch gel products with different textural properties.

miR-92a-3p regulates ethanol-induced apoptosis in H9c2 cardiomyocytes.

The role of miR-92a-3p in the ethanol-induced apoptosis of H9c2 cardiomyocytes remains unclear. In this study, we explored the role of miR-92a-3p in the ethanol-induced apoptosis of H9c2 cardiomyocytes and identified its target genes and signaling pathways. H9c2 cells were cultured with or without 100 mM ethanol for 24 h. The differential expression of miR-92a-3p was verified in H9c2 cells through reverse transcription-quantitative polymerase chain reaction (RT-qPCR). To manipulate the expression of miR-92a-3p, both a mimic and an inhibitor were transfected into H9c2 cells. An Annexin V-fluorescein isothiocyanate/propidium iodide apoptosis detection kit and apoptosis-related antibodies were used for apoptosis detection through flow cytometry and Western blotting, respectively. Target genes were verified through RT-qPCR, Western blotting, and double luciferase reporter gene assays. miR-92a-3p was significantly overexpressed in ethanol-stimulated H9c2 cardiomyocytes (P < 0.001). After ethanol stimulation, H9c2 myocardial cells exhibited increased apoptosis. The apoptosis rate was higher in the miR-92a-3p mimic group than in the control group. However, the apoptosis rate was lower in the miR-92a-3p inhibitor group than in the control group, indicating that miR-92a-3p promotes the ethanol-induced apoptosis of H9c2 myocardial cells. RT-qPCR and Western blotting revealed that the miR-92a-3p mimic and inhibitor significantly regulated the mRNA and protein expression levels of mitogen- and stress-activated protein kinase 2 and cyclic AMP-responsive element-binding protein 3-like protein 2 (CREB3L2), suggesting that miR-92a-3p promotes the apoptosis of H9c2 cardiomyocytes by inhibiting the MSK2/CREB/Bcl-2 pathway. Therefore, the apoptosis of H9c2 cardiomyocytes increases after ethanol stimulation, and miR-92a-3p can directly target MSK2 and CREB3L2, thereby promoting the ethanol-induced apoptosis of H9c2 myocardial cells.

Association between the copy number variations of Methyl-CpG binding domain family and schizophrenia.

Schizophrenia is recognized as one of the most severe psychiatric disorders, with its pathogenesis likely involving genetic, epigenetic, developmental, and environmental factors. Members of the Methyl-CpG Binding Domain (MBD) Family play a crucial role in the regulation of genomic DNA methylation, and studies have implicated the association between MBD family and neurodevelopmental disorders. Copy number variations (CNVs) are a significant genetic basis for human genomic variation, also playing a critical role in the genetic processes of schizophrenia. Therefore, we aimed to evaluate the susceptibility of MBD family CNVs to schizophrenia by exploring and validating them in two separate populations using CNVplex™ and qPCR methods, and to explore the relationship between MBD family CNVs and clinical phenotypes in the overall population using chi-square tests and Fisher's exact tests. Results suggest that an increase in MBD1 gene copy number and a deficiency in MBD2 gene copy number may be associated with the risk of schizophrenia. The deficiency in MBD2 gene copy number may increase the risk of delusion of reference and delusion of persecutory in the overall sample, as well as in males. This research provides preliminary evidence supporting the association between MBD family CNVs and schizophrenia, highlighting the potential role of the MBD family in the pathogenesis of schizophrenia.

Raman-Activated Cell Ejection for Validating the Reliability of the Raman Fingerprint Database of Foodborne Pathogens.

Raman spectroscopy for rapid identification of foodborne pathogens based on phenotype has attracted increasing attention, and the reliability of the Raman fingerprint database through genotypic determination is crucial. In the research, the classification model of four foodborne pathogens was established based on t-distributed stochastic neighbor embedding (t-SNE) and support vector machine (SVM); the recognition accuracy was 97.04%. The target bacteria named by the model were ejected through Raman-activated cell ejection (RACE), and then single-cell genomic DNA was amplified for species analysis. The accuracy of correct matches between the predicted phenotype and the actual genotype of the target cells was at least 83.3%. Furthermore, all anticipant sequencing results brought into correspondence with the species were predicted through the model. In sum, the Raman fingerprint database based on Raman spectroscopy combined with machine learning was reliable and promising in the field of rapid detection of foodborne pathogens.

Copy number deletion of PLA2G4A affects the susceptibility and clinical phenotypes of schizophrenia.

Phospholipase A2(PLA2) superfamily is recognized as being involved in the pathogenesis of schizophrenia by affecting lipid homeostasis in cell membranes. We hypothesized that PLA2 gene copy number variation (CNV) may affect PLA2 enzyme expression and be associated with schizophrenia risk. This study indicated that in the discovery stage, an increased copy number of PLA2G6 and the deletion of PLA2G3, PLA2G4A, PLA2G4F and PLA2G12F was associated with increased risk of schizophrenia. CNV segments involving six PLA2 genes were detected in publicly available datasets, including two deletion segments specific to the PLA2G4A gene. The relationship between the deletion of PLA2G4A and susceptibility to schizophrenia was then reaffirmed in the validation group of 806 individuals. There was a significant correlation between PLA2G4A deletion and the symptoms of poverty of thought in male patients and erotomanic delusion in females. Furthermore, ELISA results demonstrate a significant decrease in peripheral blood cytosolic PLA2(cPLA2) levels in patients with the PLA2G4A deletion genotype compared to those with normal and copy number duplicate genotypes. These data suggest that the functional copy number deletion in the PLA2G4A gene is associated with the risk of schizophrenia and clinical phenotypes by reducing the expression of cPLA2, which may be an indicator of susceptibility to schizophrenia.

Characteristics of hospitalized elderly patients with CKD: a comparison between elderly and non-elderly CKD based on a multicenter cross-sectional study.

PURPOSE: We undertook a multicenter epidemiological survey among hospitalized patients with chronic kidney disease (CKD), aiming to reveal the characteristics of elderly CKD by comparing it with non-elderly CKD. METHODS: Medical records were obtained from 18 military hospitals across China from 1 January 2009 to 31 December 2011. The characteristics of chronic kidney disease in the elderly were analyzed through comparing with those in younger patients with chronic kidney disease. RESULTS: A total of 380,461 hospitalized patients were included in the database, with 25,826 (6.8%) diagnosed with CKD. Unlike non-elderly, the top-three causes of chronic kidney disease among elderly patients were diabetic nephropathy (24.1%), hypertension-related renal impairment (20.9%), and primary glomerular disease (11.1%). 71.6% of the elderly patients with CKD had more than one comorbidities and the number of morbidities increased with age. In-hospital mortality of the elderly was significantly higher than those of younger patients (3.3% vs. 1.0%). Multiple logistic regression analysis showed that age, CKD 5 stage, acidosis, cardiovascular and cerebrovascular diseases, infection disease, neoplasm, and dementia were independent risk factors for death from CKD in the elderly. The median length of stay (LOS) was similar between elderly and younger CKD patients. The median cost was higher for elderly CKD patients than for younger CKD patients. Among elderly individuals with CKD, LOS, and hospitalization costs also increased with an increase in the number of coexisting diseases. CONCLUSIONS: Diabetic nephropathy,  and hypertension-related kidney injury were the leading causes of chronic kidney disease in elderly patients, which is different from the non-elderly. Elderly patients with chronic kidney disease were more likely to have a higher burden of comorbidities, which were associated with worse in-hospital outcomes.

Machine learning-based diagnosis and prognosis of IgAN: A systematic review and meta-analysis.

Purpose: Plenty of studies have explored the diagnosis and prognosis of IgA nephropathy (IgAN) based on machine learning (ML), but the accuracy lacks the support of evidence-based medical evidence. We aim at this problem to guide the precision treatment of IgAN. Methods: Embase, Pubmed, Cochrane Library, and Web of Science were searched systematically until February 24th, 2024, for publications on ML-based diagnosis and prognosis of IgAN. Subgroup analysis or meta-regression was conducted according to modeling method, follow-up time, endpoint definition, and variable type. Further, the rank sum test was applied to compare the discrimination ability of prognosis. Results: A total of 47 studies involving 51,935 patients were eligible. Among the 38 diagnostic models, the pooled C-index was 0.902 (95 % CI: 0.878-0.926) in 27 diagnostic models. Of the 162 prognostic models, the C-index for model discrimination of 144 prognostic models was 0.838 (95 % CI: 0.827-0.850) in training. The overall discrimination ability of prognosis was as follows: COX regression > new ML models (e.g. ANN, DT, RF, SVM, XGBoost) > traditional ML models (logistic regression) > Naïve Bayesian network (P < 0.05). External validation of IIgAN-RPT in 19 models showed a pooled C-index of 0.801 (95 % CI: 0.784-0.817). Conclusions: New ML models have shown application values that are as good as traditional ML models, both in diagnosis and prognosis. In addition, future models are desired to use a more sensitive prognostic endpoint (albuminuria), improve predictive ability in moderate progression risk, and ultimately translate into clinically applicable intelligent tools.

Occurrence and distribution of phytic acid and its degradation products in soybeans in China: Analytical challenges.

Phytic acid (IP6) and its degradation products lower myo-inositol phosphates exert different impacts on nutrient bioavailability and product quality characteristics. However, information regarding the occurrence of IP6 and its degradation products is scarce. In this work, simultaneous determination of IP6 and its degradation products in soybeans was developed, with emphasis on analysis by UPLC-MS/MS and a BEH Amide column both with hybrid surface technology. The retention and analyte/metal surface interactions issues were effectively addressed without ion-pairing reagents addition or derivatization. This method was applied to analyze soybeans from China. Total contents were 0.44-13.2 mg/g, and IP6 and its degradation product myo-inositol pentakisphosphate (IP5) were the predominant analytes, accounting for over 99%. Accession type significantly affected IP5 content, and landraces had significantly higher IP5 than cultivars. Geographically, the lowest IP6 was concentrated in the Huanghuaihai region. Significant correlations existed between IP6 and longitude, altitude, and annual cumulative sunshine hours. This study provides comprehensive insights into the IP6 and its degradation product profile in soybeans, which will benefit breeding soybeans based on specific requirements.

Association Between Vascular Adhesion Protein-1 (VAP-1) and MACE in Patients with Coronary Heart Disease: A Cohort Study.

Background: Vascular adhesion protein-1 (VAP-1), an inflammation-inducible endothelial cell molecule, was reported to be implicated in a variety of cardiovascular diseases. However, the clinical significance of circulating VAP-1 levels in patients with coronary heart disease (CHD) remains less studied. Patients and Methods: We retrospectively analyzed clinical data of 336 hospitalized patients in the Second Affiliated Hospital of Soochow University from May 2020 to September 2022, 174 of which were diagnosed with CHD. Serum VAP-1 was measured by enzyme-linked immunosorbent assay at enrollment. The primary end point of this study was the occurrence of major adverse cardiovascular events (MACE). The coronary stenosis and clinical manifestations of CHD were assessed and recorded from medical records or follow-up calls. The relevant results were obtained, and the reliability of the conclusions was verified through regression analysis, curve fitting, and survival curve. Results: After adjusting for potential confounders, higher serum VAP-1 level was associated with increased risk of MACE in patients with CHD [(HR = 5.11, 95% CI = 1.02-25.59), (HR = 5.81, 95% CI = 1.16-29.11)]. The results of curve fitting and survival analysis were consistent with those of regression analysis. However, no significant association was observed between VAP-1 and MACE in the entire study population [(HR = 5.11, 95% CI = 0.41-1.93), (HR = 1.17, 95% CI = 0.52-2.62)]. Furthermore, the level of VAP-1 did not show a significant correlation with coronary stenosis and the clinical manifestations of CHD. Conclusion: These findings suggested that CHD patients with higher serum levels of VAP-1 are at a higher risk of adverse cardiovascular outcomes.

Renin-angiotensin system inhibitors prescriptions in Chinese hospitalized chronic kidney disease patients.

BACKGROUND: Many guidelines have recommended renin-angiotensin system inhibitors (RASI) as the first-line treatment for patients with chronic kidney disease (CKD). We studied RASI prescription trends from 2010 to 2019, and analyzed the characteristics associated with RASI prescription in Chinese hospitalized CKD patients. AIM: To study the prescription of renin angiotensin system inhibitors in hospitalized patients with CKD in China. METHODS: It was retrospectively, cross-sectional reviewed RASI prescriptions in hospitalized CKD patients in China from 2010 to 2019. RASI prescribing trends were analyzed from 2010 to 2019, and bivariate and multivariate logistic regression analyses were conducted to identify characteristics associated with RASI prescription. RESULTS: A total of 35090 CKD patients were included, with 10043 (28.6%) RASI prescriptions. Among these patients, 18919 (53.9%) met the criteria for RASI treatments based on the 2012 kidney disease: Improving global outcomes guidelines. Of these, 7246 (38.3%) patients received RASI prescriptions. RASI prescriptions showed an initial rapid increase from 2011 to 2012, reached its peak around 2015 and 2016, and then exhibited a subsequent slight decreasing trend. Both bivariate and multivariate analyses showed that several characteristics, including the male gender, age less than 60-year-old, nephrology department admission, lower CKD stage, history of hypertension or diabetes, proteinuria, glomerulonephritis as the CKD etiology, and non-acute kidney injury were associated with RASI prescriptions. CONCLUSION: The frequency of RASI prescriptions showed an initial increase but a slight decreasing trend in more recent years. CKD patients with certain characteristics such as elderly age, advanced disease stage, surgery department admission, or acute kidney injury were less likely to receive RASI prescriptions. In the application of RASI in hospitalized CKD patients is insufficient. The actual clinical practice needs to be improved. The development of related research is helpful to guide the correct choice of clinical treatment strategy.

Decreased serum levels of SETD1A protein in patients with schizophrenia.

OBJECTIVE: SET domain-containing protein 1A (SETD1A) histone lysine N-methyltransferase may serve as a biomarker for the auxiliary diagnosis and treatment assessment of schizophrenia (SCZ). The aim of this study was to compare serum levels of SETD1A protein between patients with SCZ and health controls. METHODS: Patients with SCZ and health controls were recruited from the Sixth Hospital of Changchun and the 'Survey on Chronic Diseases and Risk Factors among Adults in Jilin Province', respectively. The quantifications of lysine N-methyltransferase in peripheral serum were conducted by the ELISA method, and data was analyzed using the R software. RESULTS: Forty patients with SCZ (mean age: 33.97 ± 5.99 years) and forty healthy controls (mean age: 39.07 ± 4.62 years) were included. There was significantly lower concentration of SETD1A protein in the SCZ group compared with the control group (P < 0.001). This significant difference still exists after stratification by sex (P < 0.05). CONCLUSION: Our study demonstrates that decreased levels of serum SETD1A protein may be utilized as a possible peripheral biomarker for schizophrenia.

COVID-19 vaccination willingness among people living with HIV in Shijiazhuang, China: a cross-sectional survey.

Objectives: The COVID-19 pandemic imposed an enormous disease and economic burden worldwide. SARS-CoV-2 vaccination is essential to containing the pandemic. People living with HIV (PLWH) may be more vulnerable to severe COVID-19 outcomes; thus, understanding their vaccination willingness and influencing factors is helpful in developing targeted vaccination strategies. Methods: A cross-sectional study was conducted between 15 June and 30 August 2022 in Shijiazhuang, China. Variables included socio-demographic characteristics, health status characteristics, HIV-related characteristics, knowledge, and attitudes toward COVID-19 vaccination and COVID-19 vaccination status. Multivariable logistic regression was used to confirm factors associated with COVID-19 vaccination willingness among PLWH. Results: A total of 1,428 PLWH were included, with a 90.48% willingness to receive the COVID-19 vaccination. PLWH were more unwilling to receive COVID-19 vaccination for those who were female or had a fair/poor health status, had an allergic history and comorbidities, were unconvinced and unsure about the effectiveness of vaccines, were unconvinced and unsure about the safety of vaccines, were convinced and unsure about whether COVID-19 vaccination would affect ART efficacy, or did not know at least a type of domestic COVID-19 vaccine. Approximately 93.00% of PLWH have received at least one dose of the COVID-19 vaccine among PLWH, and 213 PLWH (14.92%) reported at least one adverse reaction within 7 days. Conclusion: In conclusion, our study reported a relatively high willingness to receive the COVID-19 vaccination among PLWH in Shijiazhuang. However, a small number of PLWH still held hesitancy; thus, more tailored policies or guidelines from the government should be performed to enhance the COVID-19 vaccination rate among PLWH.

Regional green total factor performance analysis of China's construction industry based on a unified framework combining static and dynamic indexes.

It has an important meaning to improve green total factor performance in the construction industry for China's green and high-quality development. In addition to the traditional desirable economic output and undesirable CO2 emission output, the indicators representing social welfare of China's construction industry were incorporated into the total factor framework. On this basis, a global non-radial DEA approach was employed to explore the sources and the key factors leading to changes in regional green total factor performance of China's construction industry from both static and dynamic perspectives. The results were concluded as follows: (1) The lower energy efficiency and CO2 emission efficiency were the main reasons for low level of green total factor efficiency. During the sample period, energy efficiency increased rapidly while capital efficiency remained almost unchanged. (2) The green total factor productivity demonstrated an increasing trend, which was driven by technological progress rather than technical efficiency. An in-depth decomposition revealed that the deterioration of technical efficiency was mainly caused by the negative effect of CO2 emissions. (3) Regional green total factor performance of China's construction industry demonstrated obvious spatial heterogeneity. Each province should comprehensively consider its own characteristics of green development in the construction industry to formulate the corresponding optimization strategy. These findings can help decision makers design specific policies on regional-oriented green development of China's construction industry.
