Correlation between Retinol Binding Protein 4 and CT Perfusion Imaging and Prognosis in Patients with Acute Ischemic Stroke Based on Cell Imaging Data Analysis.

Objective: In order to explore the correlation between the retinol binding protein 4 (RBP4) and prognosis of patients with acute ischemic stroke (AIS), CT perfusion imaging can be used to scan the brain tissue of patients, which can identify abnormal perfusion areas and ischemic penumbra brain tissue, so as to provide a basis for doctors to formulate a reasonable clinical treatment plan. Methods: 200 patients with first-episode acute ischemic stroke were selected from the Department of Neurology of our hospital, including 128 males and 72 females, aged between 32 and 85 years, with an average age of 45 ± 4.3 years. After admission, the patients were tested for xanthol binding protein 4 in time, the patient's demographic data and the basic clinical data were recorded, the degree of brain injury was evaluated, and the short-term outcome was evaluated after treatment. Results: A total of 200 AIS patients with different degrees of brain injury were included in this study, including 128 males and 78 females, aged between 32 and 85 years, with an average age of 45 ± 4.3 years. Among them, 100 patients used CT perfusion imaging for brain scanning as the observation group, 100 patients used traditional imaging methods as the reference group, and 100 healthy people were included as the blank group. At the same time, the contents of total cholesterol, triacylglycerol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol were measured by using an automatic biochemical analyzer. The patients were evaluated in the early stage of treatment and the effect of prognostic intervention was recorded. Conclusion: The application of CT perfusion imaging in the adjuvant treatment of AIS patients was helpful to identify the abnormal perfusion area and the brain tissue of ischemic penumbra, so as to provide a basis for doctors' follow-up treatment. At the same time, AIS patients with high serum RBP4 level had mild stroke severity, good short-term prognosis, and improved treatment effect, which improved patients' quality of life.

Adverse childhood experiences, mindfulness and happiness in Chinese college students during the COVID-19 pandemic.

The rise of literature on adverse childhood experiences (ACEs) has indicated a strong relationship between ACEs and negative life outcomes, leading to important implications for services to the population. However, less is known about the effects of ACEs on happiness and the role of mindfulness in this relation. This study examined the relationships between ACEs and happiness and whether mindfulness mediated the effects of ACEs on happiness in a sample of Chinese college students. The data were collected from 1871 college students from 12 colleges across China in September 2020. The findings of this study show that ACEs had significant negative effects on students' happiness and that mindfulness helped to substantially reduce the negative effects of ACEs on happiness. Students who experienced emotional neglect and abuse in childhood were affected the most. By contrast, this group is not the primary focus of mindfulness-based interventions in existing literature; thus, this study calls for specific mindfulness-based interventions for this vulnerable population.

Adverse Childhood Experiences and Mindfulness in Chinese College Students During the COVID-19 Pandemic.

Mindfulness has been found to have many positive effects on life outcomes, including mental health and educational achievement. However, less is known about the antecedents of mindfulness, particularly in Chinese college students. This study examines the effect of adverse childhood experiences (ACEs) on mindfulness among Chinese college students in September 2020, during the COVID-19 pandemic. We hypothesized that ACEs negatively affected students' mindfulness. The data were collected from 1,871 college students from 12 colleges across China. The results aligned with our hypothesis that ACEs was negatively associated with mindfulness. In particular, emotional abuse and neglect in childhood appear to have the most negative effects on mindfulness compared to other dimensions of ACEs such as physical abuse and household challenges.

Adverse Childhood Experiences and Psychological Well-Being in Chinese College Students: Mediation Effect of Mindfulness.

Literature on the antecedents of psychological well-being (PWB) has found that adverse childhood experiences (ACEs) and mindfulness are associated with PWB; less is known, however, about the role of mindfulness, a type of emotional and self-regulation, in the pathway between ACEs and PWB. This study used data from 1871 college students across China to examine the relation between ACEs and PWB, and whether the relation was mediated by mindfulness. The findings from structural equation modelling indicate a statistically significant negative association between ACEs and PWB, while mindfulness was strongly and positively associated with PWB. The effect of ACEs on PWB was reduced once mindfulness was controlled for in the analysis. This provides evidence that mindfulness was able to partially mediate the effects of negative life experiences on psychological well-being. This calls for mindfulness interventions targeted toward students with a history of ACEs to buffer the effects of ACEs on PWB.

Glycyrrhizic-Acid-Based Carbon Dots with High Antiviral Activity by Multisite Inhibition Mechanisms.

With the gradual usage of carbon dots (CDs) in the area of antiviral research, attempts have been stepped up to develop new antiviral CDs with high biocompatibility and antiviral effects. In this study, a kind of highly biocompatible CDs (Gly-CDs) is synthesized from active ingredient (glycyrrhizic acid) of Chinese herbal medicine by a hydrothermal method. Using the porcine reproductive and respiratory syndrome virus (PRRSV) as a model, it is found that the Gly-CDs inhibit PRRSV proliferation by up to 5 orders of viral titers. Detailed investigations reveal that Gly-CDs can inhibit PRRSV invasion and replication, stimulate antiviral innate immune responses, and inhibit the accumulation of intracellular reactive oxygen species (ROS) caused by PRRSV infection. Proteomics analysis demonstrates that Gly-CDs can stimulate cells to regulate the expression of some host restriction factors, including DDX53 and NOS3, which are directly related to PRRSV proliferation. Moreover, it is found that Gly-CDs also remarkably suppress the propagation of other viruses, such as pseudorabies virus (PRV) and porcine epidemic diarrhea virus (PEDV), suggesting the broad antiviral activity of Gly-CDs. The integrated results demonstrate that Gly-CDs possess extraordinary antiviral activity with multisite inhibition mechanisms, providing a promising candidate for alternative therapy for PRRSV infection.
