RESUMEN
Objective:To investigate the application effects of MOTOmed in stepped individualized rehabilitation intervention of older adult patients with post-stroke hemiplegia.Methods:A total of 130 older adult patients with post-stroke hemiplegia who received treatment in the Affiliated People's Hospital of Ningbo University from June 2019 to June 2021 were included in this study. They were randomly assigned to undergo either stepped individualized rehabilitation intervention with MOTOmed training system (observation group, n = 65) or routine rehabilitation intervention (control group, n = 65) for 1 month. Before and after intervention, the Fugl- Meyer Assessment score, Berg Balance Scale score, Functional Ambulation Category scale score, modified Ashworth scale score, and modified Barthel Index, Self-Perceived Burden Scale score, nerve growth factor, brain-derived neurotrophic factor and neurotrophin 3 levels were compared between the two groups. Results:After intervention, Fugl-Meyer Assessment and Berg Balance Scale scores in the observation groups were (75.48 ± 6.54) points and (48.55 ± 5.18) points, which were significantly greater than (72.55 ± 6.33) points and (46.50 ± 4.79) points in the control group ( t = 2.59, 2.34, both P < 0.05). Functional Ambulation Category scale score in the observation group was significantly higher than that in the control group [(3.22 ± 0.43) points vs. (3.05 ± 0.39) points, t = 2.36, P < 0.05). Modified Ashworth scale score in the observation group was significantly lower than that in the control group [(1.23 ± 0.24) points vs. (1.33 ± 0.26) points, t = 2.27, P < 0.05). Modified Barthel Index score in the observation group was significantly higher than that in the control group [(59.32 ± 5.18) points vs. (57.33 ± 4.92) points, t = 2.24, P < 0.05]. There was no significant difference in Self-Perceived Burden Scale score between the two groups ( t = 1.64, P > 0.05). Nerve growth factor level in the observation group was significantly higher than that in the control group [(12.93 ± 2.31) ng/L vs. (12.06 ± 2.29) ng/L, t = 2.15, P < 0.05]. There were no significant differences in brain-derived neurotrophic factor and neurotrophin 3 levels between the two groups ( t = 0.91, 1.25, both P > 0.05). Conclusion:The stepped individualized rehabilitation intervention with MOTOmed training system can greatly improve the limb function, balance ability, walking ability and self-care ability, reduce muscle tension, and increase nerve growth factor level in older adult patients with post-stroke hemiplegia, which are conducive to the rehabilitation and prognosis of post-stroke hemiplegia.
RESUMEN
As the main active ingredient in Chinese medicine safflower, hydroxysafflor yellow A (HSYA) has multiple pharmacological effects. In the work, the absorption and fluorescence spectra of HSYA under different environmental conditions (such as acidity, temperature, ions, viscosity, and surfactant) were investigated. The fluorescence intensity of HSYA varied greatly with acidity, temperature, viscosity, and surfactant, but was less affected by common cations and anions. Among various surfactants, we found that borax can significantly enhance the HSYA fluorescence intensity, and thus, a borax-HSYA sensitization system for HSYA fluorescence was established. In the optimized sensitization system, the fluorescence intensity of HSYA increased by 20 times and showed a good linearity with HSYA concentrations in the range of 0â¼10 µM with a detection limit of 8 nM. The borax-HSYA sensitization system is nontoxic to T24 cells and mice and can be used for the fluorescence imaging of HSYA in cells, thereby providing an effective method for analyzing HSYA in vitro and monitoring its metabolism in cells.
RESUMEN
Duchenne muscular dystrophy(DMD)is a fatal muscular wasting disease in children.Because of various factors such as DMDˊs low incidence,quick progression,limited knowledge of this disease,and treat-ment outcomes of respiratory failure,heart failure has become the leading cause of death in these patients.Early diagnosis and treatment is essential for prolonging the survival time and improving the quality of life.This review describes recent progress in the study of epidemiology,pathogenesis,early diagnosis,prevention and treatment of cardiac injury in patients with DMD.
