As the place for gas exchange, the lungs are metabolically active, and their energy consumption are essential for regulating common cell functions and maintaining the unique function of lung tissues to synthesize pulmonary surfactants. The metabolic pathways of pulmonary cells mainly include glycolysis, pentose phosphate pathway, and tricarboxylic acid cycle. Recent studies have found that changes in pulmonary cells metabolism are closely related to a variety of lung diseases. Herein, we review the main pathways of pulmonary cells metabolism and the relationship between changes in cell metabolism and the four lung diseases of chronic obstructive pulmonary disease (COPD), asthma, idiopathic pulmonary fibrosis (IPF), and pulmonary hypertension (PH), to find new ways to treat lung diseases.

Objective:To understand the status quo and influencing factors of evidence-based nursing competencies among oncology nurses and provide a reference for enhancing this competency among oncology nurses.Methods:From September 2022 to January 2023, totally 300 practicing nurses from Zhejiang Cancer Hospital were selected by convenience sampling and surveyed with the Chinese version of the Evidence-Based Practice Belief-Knowledge-Practice Scale. Univariate analysis and multiple linear regression were employed to analyze factors affecting the evidence-based nursing competencies of these nurses.Results:The evidence-based nursing competency scores of the 300 oncology nurses were (44.50±10.78) . Among the three dimensions, the belief dimension had the highest average item score, while the practice dimension had the lowest. Multiple linear regression analysis revealed that gender, age, evidence-based training, participation in evidence-based projects, reading professional literature, publication of papers within the last five years and medical statistical level were influencing factors of their evidence-based nursing competencies (all P<0.05) . Conclusions:The evidence-based nursing competencies of oncology nurses are at a relatively low level. Nursing managers and educators should focus on female nurses, older nurses, intensify evidence-based nursing training efforts, and thus enhance the evidence-based nursing competencies and overall research quality of the nursing team.

Clopidogrel is one of the anti-platelet drugs, which is widely used in the world.It plays an important role in the treatment of patients with acute coronary syndrome and those undergoing percutaneous coronary intervention.Clopidogrel is effective in inhibiting the activity of platelets, decreasing the incidence of thrombosis in the stent, and then reducing the risk of adverse cardiovascular events in affected individuals. However, some patients still have coronary thrombosis after taking clopidogrel.This phenomenon is known as clopidogrel resistance or clopidogrel non-response or low response. Identification of clopidogrel resistance is of great significance in preventing the occurrence of adverse cardiovascular events.This paper provides guidance for the clinical treatment of clopidogrel resistance by discussing the definition, mechanisms and laboratory evaluation of clopidogrel resistance.

Objective:To investigate factors associated with the concentration of hydroxychloroquine (HCQ) and its metabolites in peripheral blood of patients with systemic lupus erythematosus (SLE) who were receiving long-term oral HCQ treatment.Methods:SLE patients who had been taking HCQ for more than 3 months were recruited. Clinical characteristics, laboratory test results and SLE disease activity index (SLEDAI) scores were examined. The concentrations of HCQ and its metabolites from peripheral blood were measured by high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS). Student's-test and Nonpara-metric tests were used to compare quantitative data, Chi-square and Fisher's exact tests were used to analyze qualitative data. Correlation between the test results was assessed by correlation coefficient. Variables with P values less than 0.05 in univariate analysis were entered into a logistic regression model. Results:In total, 191 SLE patients on long-term HCQ treatment were included in the analysis. Medians of HCQ blood concentrations ([HCQ]), desethylhydroxychloroquine (DHCQ) blood concentrations ([DHCQ]), desethylchloroquine (DCQ) blood concentrations ([DCQ]) and bisdesethylchloroquine (BDCQ) blood concentrations ([BDCQ]) were 523.19 (402.63, 677.88) ng/ml, 291.79 (212.30, 432.51) ng/ml, 49.37 (35.00, 73.05) ng/ml, 21.78(14.37, 52.46) ng/ml respectively. On multivariate analysis, weight-adjusted oral HCQ dose [ OR(95% CI)=1.366 (1.053, 1.772) , P=0.019], the course of hydroxychloroquine [ OR (95% CI) =0.991 (0.984, 0.999), P=0.026], estimated glomerular filtration rate [ OR(95% CI)=0.984 (0.971, 0.997), P=0.014] and platelet count [ OR (95% CI)=1.010 (1.005, 1.015), P<0.001] were associated with [HCQ]. [HCQ], [DCQ], [BDCQ], [BDCQ]/[HCQ] were negatively correlated with estimated glomerular filtration rate (eGFR) ( r=-0.20, P=0.006; r=-0.19, P=0.010; r=-0.26, P<0.001; r=-0.15, P=0.044, respectively) after adjusted for age, course of disease, duration of HCQ treatment and weight adjusted HCQ dosage, [DHCQ]/[HCQ] was negatively correlated with the SLEDAI score ( r=-0.16, P=0.027) when the effects of glucocorticoid was controlled, [BDCQ]/[HCQ] among different renal function levels was statistically significant ( H=12.46, P=0.014). Conclusion:The factors associated with HCQ blood concentrations in SLE patients on long-term oral HCQ treatment are weight-adjusted HCQ dosage, duration of hydroxychloroquine intake and renal function. In addition, [BDCQ] is closely correlated with renal function, [DHCQ] is correlated with SLE disease activity.

The human brain undergoes rapid development during childhood, with significant improvement in a wide spectrum of cognitive and affective functions. Mapping domain- and age-specific brain activity patterns has important implications for characterizing the development of children’s cognitive and affective functions. The current mainstay of brain templates is primarily derived from structural magnetic resonance imaging (MRI), and thus is not ideal for mapping children’s cognitive and affective brain development. By integrating task-dependent functional MRI data from a large sample of 250 children (aged 7 to 12) across multiple domains and the latest easy-to-use and transparent preprocessing workflow, we here created a set of age-specific brain functional activity maps across four domains: attention, executive function, emotion, and risky decision-making. Moreover, we developed a toolbox named Developmental Brain Functional Activity maps across multiple domains that enables researchers to visualize and download domain- and age-specific brain activity maps for various needs. This toolbox and maps have been released on the Neuroimaging Informatics Tools and Resources Clearinghouse website (http://www.nitrc.org/projects/dbfa). Our study provides domain- and age-specific brain activity maps for future developmental neuroimaging studies in both healthy and clinical populations.

Drug-associated reward memories are conducive to intense craving and often trigger relapse. Simvastatin has been shown to regulate lipids that are involved in memory formation but its influence on other cognitive processes is elusive. Here, we used a mass spectrometry-based lipidomic method to evaluate the impact of simvastatin on the mouse brain in a cocaine-induced reinstatement paradigm. We found that simvastatin blocked the reinstatement of cocaine-induced conditioned place preference (CPP) without affecting CPP acquisition. Specifically, only simvastatin administered during extinction prevented cocaine-primed reinstatement. Global lipidome analysis showed that the nucleus accumbens was the region with the greatest degree of change caused by simvastatin. The metabolism of fatty-acids, phospholipids, and triacylglycerol was profoundly affected. Simvastatin reversed most of the effects on phospholipids induced by cocaine. The correlation matrix showed that cocaine and simvastatin significantly reshaped the lipid metabolic pathways in specific brain regions. Furthermore, simvastatin almost reversed all changes in the fatty acyl profile and unsaturation caused by cocaine. In summary, pre-extinction treatment with simvastatin facilitates cocaine extinction and prevents cocaine relapse with brain lipidome remodeling.
