RESUMO
BACKGROUND: The genetic component of dyslipidemia has been studied in adults but little in older population. It is remains unknown regarding influence and interaction of APOA5 gene single nucleotide polymorphism (SNP) and habitual aerobic exercise (HAE) on changes of blood lipids and lipoprotein phenotypes in older Chinese adults. METHODS: Four-hundred-twenty-three old Chinese individuals with HAE were divided into hyperlipidemia and normal groups. We genotyped polymorphic loci using matrix assisted laser desorption ionization time of flight mass spectrometry detection technology (MALDI-TOF). HAE level was assessed by International Physical Activity Questionnaire (IPAQ) scale. RESULTS: For three genotypes of rs662799 site, the AGâ¯+â¯GG gene carriers presented higher risk of hyperlipidemia compared to the AA carriers, with the ratio of 1.676 (Pâ¯=â¯.018, 95% CI: 1.092-2.571) for the AG and 1.812 (Pâ¯=â¯.002, 95% CI: 1.247-2.632) for the GG, respectively. The rs662799 G allele was significantly associated with lower HDL-C but higher TG levels. In relation to different HAE levels, less interaction was observed between the AA carriers and different HAE levels on corresponding lipids changes. The AGâ¯+â¯GG carriers with higher HAE levels had significantly lower TG responses compared to those with lower HAE levels (1.45⯱â¯0.74â¯mmol/L vs. 1.86⯱â¯1.15â¯mmol/L). CONCLUSIONS: Excess risk for low HDL-C and hyperlipidemia was associated with rs662799 genotype alleles of APOA5 SNPs in older Chinese adults. Interaction of gene-HAE and HAE levels may induce different responses of blood lipids and lipoprotein phenotypes. HAE levels have less influence on TG changes in the AA carriers; however, high HAE levels appeared to greatly impact TG responses in the AGâ¯+â¯GG carriers.

The aim of the study is to investigate the relationship between physical activity as assessed by accelerometers and cognitive development across the human age ranges (from children and adolescents to adults). Additionally, this study seeks to explore whether physical activity contributes to cognitive development via modification of plasma insulin-like growth factor 1 (IGF-1) and brain-derived neurotrophic factor (BDNF). In the study, 500 preschool children (3.5-5.5 years old) are taking part in 6 triennial assessment waves over the span of 15 years. At each wave, participant measures included (a) 7-day physical activity monitoring using ActiGraph's GT3X accelerometers, (b) the evaluation of cognitive development, (c) anthropometric and physical fitness assessments, (d) plasma IGF-1 and BDNF concentrations, and (e) retrospective questionnaires. Linear regression models are used to examine the effect of physical activity on cognitive development; plasma IGF-1 and BDNF concentrations are considered as mediators into data analyses. The results of the study may help to inform future health interventions that utilize physical activity as a means to improve cognitive development in children, adolescents, and adults. Additionally, the study may assist in determining whether the putative effects occur via modification of plasma IGF-1 or BDNF concentrations.

BACKGROUND: Traditional Chinese exercise (TCE) has widespread use for the prevention and treatment of cardiovascular disease; however, there appears to be no consensus about the benefits of TCE for patients with cardiovascular disease. The objective of this systematic review was to determine the effects of TCE for patients with cardiovascular disease. METHODS AND RESULTS: Relevant studies were searched by PubMed, Embase, Web of Science, the Cochrane Library, the Cumulative Index to Nursing and Allied Health Literature, and the China National Knowledge Infrastructure. We covered only published articles with randomized controlled trials. The outcome measures included physiological outcomes, biochemical outcomes, physical function, quality of life, and depression. A total of 35 articles with 2249 cardiovascular disease patients satisfied the inclusion criteria. The pooling revealed that TCE could decrease systolic blood pressure by 9.12 mm Hg (95% CI -16.38 to -1.86, P=0.01) and diastolic blood pressure by 5.12 mm Hg (95% CI -7.71 to -2.52, P<0.001). Patients performing TCE also found benefits compared with those in the control group in terms of triglyceride (standardized mean difference -0.33, 95% CI -0.56 to -0.09, P=0.006), 6-minute walk test (mean difference 59.58 m, 95% CI -153.13 to 269.93, P=0.03), Minnesota Living With Heart Failure Questionnaire results (mean difference -17.08, 95% CI -23.74 to -10.41, P<0.001), 36-Item Short Form physical function scale (mean difference 0.82, 95% CI 0.32-1.33, P=0.001), and Profile of Mood States depression scale (mean difference -3.02, 95% CI -3.50 to -2.53, P<0.001). CONCLUSIONS: This study demonstrated that TCE can effectively improve physiological outcomes, biochemical outcomes, physical function, quality of life, and depression among patients with cardiovascular disease. More high-quality randomized controlled trials on this topic are warranted.

Traditional Chinese exercise (TCE) has many uses in the prevention and treatment of chronic diseases. However, there is no consensus regarding the benefit of TCE for chronic diseases. Our objective is to examine the effect of TCE on the quality of life and depression for chronic diseases by performing a meta-analysis of randomized controlled trials (RCTs). We only cover published RCTs. The outcome measures included quality of life and depression. Sixty articles with a total of 4311 patients were included. The pooling revealed that TCE could improve the SF-36 physical function subscale in the short term [SMD (95% CI) = 0.35 (0.13, 0.56), P = 0.002] and mid-term [SMD (95% CI) = 0.49 (0.12, 0.85), P = 0.009], GHQ [SMD (95% CI) = -0.68 (-1.26, -0.09), P = 0.02], the Center for Epidemiologic Studies depression scale in the short term [SMD (95% CI) = -0.86 (-1.42, -0.31), P = 0.002] and mid-term [SMD (95% CI) = -0.41 (-0.64, -0.18), P < 0.001]. The meta-analysis of RCT demonstrates that TCE can significantly improve the quality of life and depression of patients with chronic diseases. These findings provide useful information for patients with chronic diseases as well as for medical staff.
