The impact of widowhood on the quality of life of older adults: the mediating role of intergenerational support from children.

BACKGROUND: China's transition into an aging society is accelerated by the simultaneous decline in fertility rates and the prolonged life expectancy of older adults. The impact of widowhood, a significant stressor in old age, has emerged as a crucial factor affecting the quality of life among the elderly. METHODS: This study is based on data from the 2018 China Health and Aging Tracking Survey. Multiple linear regression models were employed to investigate the influence of widowhood on the quality of life of older adults in China. Additionally, Bootstrap mediation effects were utilized to assess the mediating role of intergenerational support, considering both financial and emotional support from children. RESULTS: The findings indicate a substantial reduction in the quality of life index among older adults following widowhood. Moreover, the impact is more pronounced among older men compared to older women. Rural older adults experience a significant decline in quality of life post-widowhood, while the effect on urban counterparts is not statistically significant. CONCLUSIONS: Intergenerational financial support was identified as a partial mediator between widowhood and the quality of life among older adults. This underscores the importance of familial financial assistance in mitigating the adverse effects of widowhood on the well-being of the elderly. These results offer valuable insights into the nuanced impact of widowhood on the quality of life among older adults in China, emphasizing the need for targeted interventions, especially in rural areas. CLINICAL TRIAL: Not applicable.

Proteomics revealed an association between ribosome-associated proteins and amyloid beta deposition in Alzheimer's disease.

Most scholars believe that amyloid-beta (Aß) has the potential to induce apoptosis, stimulate an inflammatory cascade, promote oxidative stress and exacerbate the pathological progression of Alzheimer's disease (AD). Therefore, it is crucial to investigate the deposition of Aß in AD. At approximately 6 months of age, APP/PS1 double transgenic mice gradually exhibit the development of plaques, as well as spatial and learning impairment. Notably, the hippocampus is specifically affected in the course of AD. Herein, 6-month-old APP/PS1 double transgenic mice were utilized, and the differentially expressed (DE) proteins in the hippocampus were identified and analyzed using 4D label-free quantitative proteomics technology and parallel reaction monitoring (PRM). Compared to wild-type mice, 29 proteins were upregulated and 25 proteins were downregulated in the AD group. Gene Ontology (GO) enrichment analysis of biological processes (BP) indicated that the DE proteins were mainly involved in 'ribosomal large subunit biogenesis'. Molecular function (MF) analysis results were primarily associated with '5.8S rRNA binding' and 'structural constituent of ribosome'. In terms of cellular components (CC), the DE proteins were mainly found in 'polysomal ribosome', 'cytosolic large ribosomal subunit', 'cytosolic ribosome', and 'large ribosomal subunit', among others. Furthermore, Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis demonstrated that the results were mainly enriched in the 'Ribosome signaling pathway'. The key target proteins identified were ribosomal protein (Rp)l18, Rpl17, Rpl19, Rpl24, Rpl35, and Rpl6. The PRM verification results were consistent with the findings of the 4D label-free quantitative proteomics analysis. Overall, these findings suggest that Rpl18, Rpl17, Rpl19, Rpl24, Rpl35, and Rpl6 may have potential therapeutic value for the treatment of AD by targeting Aß.

Effect of TCM rehabilitation program on activities of daily living in patients with post-stroke limb spasticity: An observational study.

BACKGROUND: Stroke is a neurological disease with many common complications that reduce the activities of daily living and the quality of life of patients. Traditional Chinese medicine (TCM) rehabilitation techniques, scalp acupuncture, and TCM can relieve spasticity symptoms and recovery from physical obstacles is significant. METHODS: Three hundred twenty-one patients with post-stroke limb spasticity were randomly divided into trial and control groups, with 159 and 162 patients in the trial and control groups, respectively. The control group received basic treatment combined with modern rehabilitation techniques, whereas the trial group received basic treatment combined with TCM, Tuina, and scalp acupuncture with kinesiotherapy. The treatment course in both groups was 4 weeks. The Modified Ashworth Scale, magnetic resonance imaging, and Stroke Specific Quality of Life Scale were used to evaluate limb spasticity, activities of daily living, and quality of life, respectively. PASW 18.0 was used for statistical analysis. RESULTS: With a longer treatment period, the improvement in limb spasticity was greater in the trial group than in the control group (P < .05). Similarly, improvements in activities of daily living and quality of life were better in the trial group than in the control group (P < .05). CONCLUSION: The TCM rehabilitation program using Tongjing Tiaoxing combined with scalp acupuncture and kinesiotherapy can effectively treat spasticity symptoms in stroke patients and improve their activities of daily living and quality of life.

BACKGROUND: Tong Jing Tiao Xing tuina (TJTX) is a Chinese massage method. Excising with scalp acupuncture (ESA) is a treatment combining scalp electroacupuncture with physical therapy (PT), and yinao fujian formula (YNFJ) is a Chinese oral herbal granule medicine. The combination of the 3 methods is called the "Zhishen Tiaoxing" (ZSTX) rehabilitation program, which is used as an alternative of limb spasm after stroke. There is little available evidence demonstrating its safety and efficacy. METHODS: This will be a subject-blind, randomized controlled trial conducted in 3 medical centers. It will strictly follow the Standards for Reporting Interventions in Clinical Trials of Acupuncture, 2010. We will recruit 316 patients with limb spasm after stroke, 200 from the Affiliated Hospital of Changchun University of Chinese Medicine, Changchun, China, 80 from the Second Affiliated Hospital of Heilongjiang University of Chinese medicine, Harbin, China, and 36 from Huashan Hospital of Fudan University, Shanghai, China. A block randomization sequence stratified by centers will be generated using SAS Version 9.2 software (SAS Institute, Cary, NC, USA), which was performed at the Guangdong Provincial Hospital of Chinese Medicine's Key Unit of Methodology in Clinical Research. The treatment group is treated with TJTX (once a day), ESA (once a day), and oral YNFJ (twice a day). The control group will be treated with PT. Two groups of patients will be treated 5 sessions a week for 4 weeks, and there will be 6-month follow-up. The outcome evaluators will be blinded to patient grouping. The primary outcome will be modified Ashworth scales. The secondary outcome indexes will be the simplified Fugl-Meyer assessment scale, surface electromyogram root mean square value, modified Barthel index, stroke-specific quality of life scale, health scale of traditional Chinese medicine, visual analogue scale (VAS), and the Hamilton depression scale.
