ABSTRACT

Objective@#To improve the N biomarker in the amyloid/taueurodegeneration system by radiomics and study its value for predicting cognitive progression in individuals with mild cognitive impairment (MCI). @*Materials and Methods@#A group of 147 healthy controls (HCs) (72 male; mean age ± standard deviation, 73.7 ± 6.3 years), 197 patients with MCI (114 male; 72.2 ± 7.1 years), and 128 patients with Alzheimer’s disease (AD) (74 male; 73.7 ± 8.4 years) were included. Optimal A, T, and N biomarkers for discriminating HC and AD were selected using receiver operating characteristic (ROC) curve analysis. A radiomics model containing comprehensive information of the whole cerebral cortex and deep nuclei was established to create a new N biomarker. Cerebrospinal fluid (CSF) biomarkers were evaluated to determine the optimal A or T biomarkers. All MCI patients were followed up until AD conversion or for at least 60 months. The predictive value of A, T, and the radiomics-based N biomarker for cognitive progression of MCI to AD were analyzed using Kaplan-Meier estimates and the log-rank test. @*Results@#The radiomics-based N biomarker showed an ROC curve area of 0.998 for discriminating between AD and HC. CSF Aβ42 and p-tau proteins were identified as the optimal A and T biomarkers, respectively. For MCI patients on the Alzheimer’s continuum, isolated A+ was an indicator of cognitive stability, while abnormalities of T and N, separately or simultaneously, indicated a high risk of progression. For MCI patients with suspected non-Alzheimer’s disease pathophysiology, isolated T+ indicated cognitive stability, while the appearance of the radiomics-based N+ indicated a high risk of progression to AD. @*Conclusion@#We proposed a new radiomics-based improved N biomarker that could help identify patients with MCI who are at a higher risk for cognitive progression. In addition, we clarified the value of a single A/T/N biomarker for predicting the cognitive progression of MCI.

ABSTRACT

Objective To evaluate the effect of internet-based cognitive behavior therapy MoodGYM on adolescents and college students with depression symptoms through Meta-analysis. Methods Databases as Web of Science, PubMed, Cochrane Library, Embase, Chinese Biomedical Database, China National Knowledge Internet and Wanfang were searched from their establishment to January 2017 for collecting randomized controlled trails and clinical controlled trails about MoodGYM for adolescents and college students with depression symptoms. Two reviewers independently selected studies,extracted data and assessed risk of bias.RevMan 5.3 software was used to perform Meat-analysis. Results Seven studies involving 1 632 participants were included.The results of Meta-analysis showed that the score of depression, anxiety and negative automatic thoughts in MoodGYM arm was lower than control arm, the statistic results: standardized mean difference=-0.45, 95% CI-0.82--0.07, P=0.02;mean difference=-7.36,95% CI-11.88--2.85,P=0.001;mean difference=-18.06,95% CI-26.44--9.68, P<0.01, the difference between experiment arm and control arm was significant. Conclusions MoodGYM can contribute to improve depression, anxiety and negative automatic thought of adolescents and college students. This intervention should be further examined by high-quality, large-sample randomized controlled trails.

ABSTRACT

Objective To investigate the status of social support and job satisfaction of community nurses and their relationship in Wuhan. Methods A total of 230 community nurses from 20 community health service centers in Wuhan were investigated by general information questionnaire, job satisfaction scale of community nurse and social support scale. Results The total score of job satisfaction was (96.14±14.76) points, the highest score of dimension was leadership and management (23.64±4.60) points, and the lowest was pay and welfare (10.83±3.00) points. The total score of social support was (37.17±7.05) points, the highest score of dimension was perceived social support (20.15 ± 4.48) points, the lowest was availability (8.05±1.57) points. There was a positive association between community nurses′social support and job satisfaction (r=0.248, P<0.05). Conclusions Social support is one of the predictors of job satisfaction. In order to make sure the sustainable development of community health services, it is necessary to know the status and take corresponding measures to improve the levels of social support and job satisfaction.

ABSTRACT

Objective To induce adipose-derived mesenchymal stem cells (ADMSCs) differentiation into cardiomyocytes, so as to provide stem cells for myocardial regeneration.Method ADMSCs were isolated and cultured from adult adipose tissue in vitro.They were induced with 10μmol/L 5-azacytidine (5Aza) for 24h.At the 7th, 14th, 21st days after induction, the expression of α-sarcomeric actin, and myosin heavy chain were repeatedly detected by immunocytochemistry.The expression of ANP was detected by RT-PCR.Results At the 7th day after induction, there was no expression of α-sarcomeric actin and MHC.At the 14th day, there was a little expression of α-sarcomeric actin and MHC that could be seen in cells.At the 21st day, there was increased expression of α-sarcomeric and MHC, and the expression of ANP was positive results detected by RT-PCR.Conclusions 5-Aza can induced ADMSCs to differentiate into cardiomyocytes.ADMSCs might be a potential source of cell transplantation for myocardial.
