Abstract

Objective: To explore the impact of routine management compared to case management on social support and self-efficacy of patients with chronic diseases and assess the new nurse-led healthcare collaborative model. Methods: This is a prospective study which was approved by the Biomedical Ethics Committee of Anhui Medical University. A total of 100 patients with chronic diseases who received treatment and care in Hefei First People’s Hospital from January 2020 to December 2021 were selected as the study subjects and divided into a control group and an observation group according to the numerical table method, with 50 cases in each group. In the control group, conventional management was implemented, while the observation received a nurse-led healthcare collaborative care, which included community doctors providing treatment services and family doctors contracting to manage care. The patients in the two groups were compared in terms of self-efficacy, self-management ability, social support, and their attendance. Results: Before the intervention, there was no statistically significant difference in self-efficacy, compliance and quality of life scores between the two groups (P>0.05). After the intervention, self-efficacy, compliance and quality of life scores were significantly higher in the observation group than those in the control group, with statistically significant differences (P

Abstract

Aluminum is a kind of metal that we often encounter. It can also be absorbed by the human body invisibly and will affect our bodies to a certain extent, e.g., by causing symptoms associated with Alzheimer's disease. Therefore, the detection of aluminum is particularly important. The methods to detect metal ions include precipitation methods and electrochemical methods, which are cumbersome and costly. Fluorescence detection is a fast and sensitive method with a low cost and non-toxicity. Traditional fluorescent nanomaterials have a high cost, high toxicity, and cause harm to the human body. Graphene quantum dots are a new type of fluorescent nanomaterials with a low cost and non-toxicity that can compensate for the defects of traditional fluorescent nanomaterials. In this paper, c-GQDs and o-GQDs with good performance were prepared by a bottom-up hydrothermal method using o-phenylenediamine as a precursor and citric acid or boric acid as modulators. They have very good optical properties: o-GQDs exhibit orange fluorescence under UV irradiation, while c-GQDs exhibits cyan fluorescence. Then, different metal ions were used for ion detection, and it was found that Al3+ had a good quenching effect on the fluorescence of the o-GQDs. The reason for this phenomenon may be related to the strong binding of Al3+ ions to the N and O functional groups of the o-GQDs and the rapid chelation kinetics. During the chelation process, the separation of o-GQDs' photoexcited electron hole pairs leads to their rapid electron transfer to Al3+, in turn leading to the occurrence of a fluorescence-quenching phenomenon. In addition, there was a good linear relationship between the concentration of the Al3+ ions and the fluorescence intensity, and the correlation coefficient of the linear regression equation was 0.9937. This illustrates the potential for the wide application of GQDs in sensing systems, while also demonstrating that Al3+ sensors can be used to detect Al3+ ions. [ABSTRACT FROM AUTHOR]
