Comparison of physical fitness and physiological function of children and adolescents with different nutritional status in Beijing Tianjin Hebei Region / 中国学校卫生

Objective@#To understand physical fitness and physiological function level of children and adolescents with different nutritional status in Beijing Tianjin Hebei Region, and to provide reference for physical health promotion and intervention of children and adolescents.@*Methods@#From September to December 2019, 4 424 children and adolescents aged 7-18 years old in Beijing Tianjin Hebei Region were tested for different nutritional status, physical fitness and physiological function by using stratified cluster sampling method.@*Results@#The detection rates of malnutrition, normal, overweight and obesity were 7.93%, 67.36% and 24.71%, respectively.There were differences in heart rate, systolic blood pressure, diastolic blood pressure, vital capacity body mass index, grip strength body mass index, oblique pull up/pull up, standing long jump, 50 m running, 1 000 m running, and BMI in boys with different nutritional status statistical significance ( Z =9.6, 55.2, 118.6, 332.5, 122.8, 15.6, 49.5, 47.5, 12.6, 113.5, P <0.01); There were differences in heart rate, systolic blood pressure, diastolic blood pressure, vital capacity body mass index, grip strength body mass index, sit up for 1 minute, standing long jump, 50 m running, 800 m running and physical fitness index in girls with different nutritional status statistical significance ( Z =33.9, 24.5, 46.5, 262.5, 102.6, 32.5, 27.5, 33.6, 27.6, 51.6, P <0.01). Correlation analysis showed that the nutritional status of boys was positively correlated with systolic blood pressure, diastolic blood pressure, 50 m running, and 1 000 m running ( r =0.27, 0.31, 0.14, 0.16, P <0.05), and was correlated with heart rate, vital capacity, body mass index, grip strength body mass index, oblique pull up/pull up, standing long jump, and BMI were negatively correlated ( r =-0.07, -0.62, -0.41, -0.21, -0.35, -0.29, P ＜0.05); nutritional status of girls it was positively correlated with systolic blood pressure, diastolic blood pressure, and 800 m running ( r =0.21, 0.27, 0.22, P <0.05), and negatively correlated with heart rate, vital capacity BMI, grip strength BMI, and BMI ( r =-0.12, -0.49, -0.32, -0.18, P <0.05).@*Conclusion@#The nutritional status of children and adolescents in Beijing Tianjin Hebei Region is related to physical fitness and physiological function. Overweight and obese child have lower physical fitness and physiological function. In the future, childhood overweight and obesity should be effectively controlled to better promote the development of physical fitness and physiological function.

Intracoronary sarcoplasmic reticulum calcium-atpase gene therapy in advanced heart failure patients with reduced ejection fraction: a prospective cohort study

OBJECTIVE: Heart failure is a progressive and debilitating disease. Intracoronary sarcoplasmic reticulum calcium-ATPase gene therapy may improve the function of cardiac muscle cells. This study aimed to test the hypothesis that intracoronary sarcoplasmic reticulum calcium-ATPase gene therapy can improve outcomes and reduce the number of recurrent and terminal events in advanced heart failure patients with reduced ejection fraction. METHODS: A total of 768 heart failure patients with reduced ejection fraction and New York Heart Association classification II to IV were included in this prospective cohort study. Patients either underwent intracoronary sarcoplasmic reticulum calcium-ATPase gene therapy (CA group, n=384) or received oral placebo (PA group; n=384). Data regarding recurrent and terminal event(s), treatment-emergent adverse effects, and outcome measures were collected and analyzed. RESULTS: After a follow-up period of 18 months, intracoronary sarcoplasmic reticulum calcium-ATPase gene therapy reduced the number of hospital admissions (p=0.001), ambulatory treatments (p=0.0004), and deaths (p=0.024). Additionally, intracoronary sarcoplasmic reticulum calcium-ATPase gene therapy improved the left ventricular ejection fraction (p<0.0001) and Kansas City Cardiomyopathy Questionnaire score (p<0.0001). The number of recurrent and terminal events/patients were higher in the PA group than in the CA group after the follow-up period of 18 months (p=0.015). The effect of the intracoronary sarcoplasmic reticulum calcium-ATPase gene therapy was independent of the confounding variables. No new arrhythmias were reported in the CA group. CONCLUSIONS: Intracoronary sarcoplasmic reticulum calcium-ATPase gene therapy reduces the number of recurrent and terminal events and improves the clinical course of advanced heart failure patients with reduced ejection fraction.

Association of rs12255372 in the TCF7L2 gene with type 2 diabetes mellitus: a meta-analysis

Our objective was to evaluate the association of rs12255372 in the TCF7L2 gene with type 2 diabetes mellitus (T2DM) in the world population. We carried out a survey of the literature about the effect of rs12255372 on genetic susceptibility to T2DM by consulting PubMed, the Cochrane Library, and Embase from 2006 to 2012, and then performed a meta-analysis of all the studies in order to evaluate the association between rs12255372 and T2DM. A total of 33 articles including 42 studies (with 34,076 cases and 36,192 controls) were confirmed to be eligible and were included in the final meta-analysis: 6 studies conducted on Europeans, 14 on Caucasians, 17 on Asians, 2 on Africans, and 3 on Americans. Overall, the effect size was as follows: for the variant allele T (OR = 1.387, 95%CI = 1.351-1.424), for the TT genotype (OR = 1.933, 95%CI = 1.815-2.057), for the GT genotype (OR = 1.363, 95%CI = 1.315-1.413), for the dominant model (OR = 1.425, 95%CI = 1.344-1.510), and for the recessive model (OR = 1.659, 95%CI = 1.563-1.761). In summary, by pooling all available qualified data from genetic studies on rs12255372 and T2DM, we have confirmed that rs12255372 is significantly associated with susceptibility to T2DM in the global population.
