ABSTRACT
Objective:To explore the effects of online character strengths intervention on the distress-related and self-management ability of young and middle-aged patients with type 2 diabetes. To provide reference for improving the physical and mental health of patients.Methods:Ninety-two young and middle-aged patients with type 2 diabetes admitted to the Second Affiliated Hospital of Xuzhou University of Medicine from July 2021 to July 2022 were selected and divided into intervention group and control group with 46 cases in each group by random number table method. The control group was given routine care, and the intervention group was given online character strengths intervention for 8 weeks. Diabetes-related distress Questionnaire (DDS) and Diabetes Self-Care Scale (DSCS) were used to evaluate the effects of the two groups of patients before intervention, immediately after intervention and 1 month after intervention.Results:The total DDS scores of the control group were (2.18 ± 0.70) and (2.01 ± 0.65) when the moment and 1 month after intervention, while the scores in the intervention group were (1.74 ± 0.47) and (1.18 ± 0.17), the differences were significant ( t = 3.13, 8.34, both P<0.05). The total DSCS scores of the control group were (72.25 ± 11.55) and (73.12 ± 10.72) when the moment and 1 month after intervention, while the scores in the intervention group were (85.95 ± 5.91) and (85.24 ± 5.21), the differences were significant ( t = 10.13, 2.10, both P<0.05). Conclusions:Online character strengths intervention can help alleviate the distress associated with young and middle-aged patients with type 2 diabetes and improve the level of self-management.
ABSTRACT
OBJECTIVE@#To investigate the effect of bone marrow stromal cell glycosyltransferase B4GALT1 expression on hematopoietic cell proliferation and its upstream regulation mechanism.@*METHODS@#B4GALT1 was overexpressed in human bone marrow stromal cell line HS5, which was then co-cultured with acute myeloid leukemia cell line KG1a. And its effect on hematopoietic cell proliferation was detected by flow cytometry. Dual luciferase reporter assay, real-time PCR and Western blot were used to predict and validate upstream transcription factors that regulate stromal cell B4GALT1 expression.@*RESULTS@#Overexpression of B4GALT1 in HS5 significantly promoted the proliferation of KG1a in the co-culture system. B4GALT1 expression in stromal cells positively correlated with upstream c-Jun expression, which was verified by JNK/c-Jun inhibitors.@*CONCLUSION@#The differential expression of glycosyltransferases and their corresponding glycosylation in the hematopoietic microenvironment play an important role.
ABSTRACT
Reactive nitrogen species (RNS) affects intracellular redox balance and induces post-translational modification of proteins. Moreover, RNS, as the signal molecule, participates in the transduction of cellular signals under physiological conditions. However, excessive RNS can induce nitrosative stress and then damage cells, and thereby may play a role in the tumor initiation and progression. Thus, we discussed the role of RNS under physiological conditions and the tumor microenvironment, which may provide some novel ideas for the development of new drugs and the treatment of diseases.
ABSTRACT
Inactivation and microbial regrowth of penicillin-, ampicillin-, cefalexin-, tetracycline-, chloramphenicol-, and rifampicin-resistant bacteria were studied to explore risks associated with selection and regrowth of antibiotic-resistant bacteria after PAA disinfection. The results showed that after exposure to 20 mg/L PAA for 10 min, inactivation of ampicillin-resistant bacteria reached 2.3-log, which was significantly higher than that of total heterotrophic bacteria with a decrease of 2.0-log. In contrast, inactivation of tetracycline- resistant bacteria was significantly less efficient, reaching only 1.1-log. Chloramphenicol-and tetracycline-resistant bacteria, as well as total heterotrophic bacteria regrew more than 10 fold compared to those in the untreated wastewater sample with 22 h stilling culture after exposure to 2 or 5 mg/L PAA as for 10 min. Selection and potential regrowth of tetracycline-and chloramphenicol-resistant bacteria are potential risks when utilizing PAA disinfection, which may induce the spread of specific antibiotic-resistant bacteria in reclaimed water.
