Depressive symptoms changes in the new-onset stroke patients: A cross-lagged panel network analysis.

Background: Each year, there are approximately 10.3 million new stroke cases worldwide, with 2 million occurring in China. Post-stroke depression (PSD) is a common complication that negatively affects rehabilitation outcomes and increases long-term mortality.

Negative emotions among Chinese primary and middle school students and association with screen time: A network analysis.

Background: Psychological health is crucial for the physical and mental well-being of primary and secondary school students, however, the research on the interrelationships among negative emotions is still limited. This study aims to investigate the network structure of depression, anxiety, and stress, and explore their correlation with screen time in these populations.

Method: This study was conducted from March to July 2022 in 157 counties across 18 cities in Henan Province.

Internship and postgraduate entrance examination: A qualitative study on the psychological experience of undergraduate nursing students under dual pressure in China.

Background: With the development of nursing positions and nursing disciplines in China's tertiary hospitals, the number of people applying for the master's degree in nursing is also increasing year by year. Postgraduate examinations are held during internship, so nursing students face the dual pressure of testing and internship, which brings varying degrees of negative experiences and emotional fluctuations.

Objective: To explore the psychological experiences and influencing factors of undergraduate nursing students under the dual pressures of clinical nursing internships and postgraduate examination preparations.

Binaphthyl-based chiral covalent organic frameworks for chiral drug separation.

Separation of racemic drugs is of great importance and interest in chemistry and pharmacology. Here, we report the bottom-up synthesis of the binaphthyl-based chiral covalent organic frameworks (CCOFs), (R)-BHTP-COF. Then, high-performance liquid chromatography (HPLC) columns were prepared using (R)-BHTP-COF as a chiral stationary phase (CSP).

Low-temperature methanation of fermentation gas with Ni-based catalysts in a multicomponent system.

A large amount of greenhouse gases, such as carbon dioxide and methane, are released during the production process of bioethanol and biogas. Converting CO into methane is a promising way of capturing CO and generating high-value gas. At present, CO methanation technology is still in the early stage.

The lysine 2-hydroxyisobutyrylome of Helicobacter pylori: Indicating potential roles of lysine 2-hydroxyisobutyrylation in the bacterial metabolism.

Helicobacter pylori (H. pylori) is a pathogen which colonizes the stomach, causing ulcers, chronic gastritis and other related diseases. Protein post-translational modifications (PTMs) in bacteria mainly include glycosylation, ubiquitination, nitrosylation, methylation, phosphorylation and acetylation, all of which have divergent functions in the physiology and pathology of the bacterium.

A network analysis of anxiety and depression symptoms in Chinese disabled elderly.

Background: Mental health is an essential dimension of healthy aging. The number and severity of disabled elderly in China show an increasing tendency year by year. Due to their impaired ability of daily activities, reduced social participation and reduced self-care ability, they are more prone to depression and anxiety.

The interaction effect of transfusion history and previous stroke history on the risk of venous thromboembolism in stroke patients: a prospective cohort study.

Background: Blood transfusion and previous stroke history are two independent risk factors of venous thromboembolism (VTE) in stroke patients. Whether the potential interaction of transfusion history and previous stroke history is associated with a greater risk of VTE remains unclear. This study aims to explore whether the combination of transfusion history and previous stroke history increases the risk of VTE among Chinese stroke patients.
