RESUMO
Objective@#To explore the correlation between hemoglobin and blood pressure.@*Methods@#This study adopted the cross-sectional design method. Participants were recruited from grade 2 in primary school, grade 1 from junior and senior high school taking physical examination, including the hemoglobin test, organized by the Guangzhou Municipal Primary and Secondary School Health and Health Promotion Center from January to December in 2015. Correlation between blood pressure and hemoglobin and determinants of blood pressure were analyzed.@*Results@#A total of 34 752 samples participated including 17 414 boys and 17 338 girls. Hemoglobin was negatively associated with systolic blood pressure (SBP) and diastolic blood pressure (DBP) among girls with anemia(P<0.01). Hemoglobin was positively associated with SBP and DBP among boys and girls with normal hemoglobin level(P<0.01). With each tertile increase in blood pressure, hemoglobin level increased by 1 mmHg. Logistic regression analysis showed that compared with peers from same grade with hemoglobin level lower than P25, the risk of suffering from pre-hypertension and hypertension among students from grade 2 with hemoglobin level greater than or equal to P75, and those from junior high and senior high schools with hemoglobin level higher than or equal to P50.@*Conclusion@#Among students without anemia population, a positive correlation between hemoglobin and SBP and DBP is observed.
RESUMO
Objective To explore clinical effect of Shenmai injection and atorvastatin in treating coronary heart disease of chronic heart failure(CHF). Methods 44 patients with coronary heart disease of chronic heart failure from April 2016 to April 2017 were included in this study as control group. They were treated with conventional symptomatic treatment, and combined with atorvastatin. 44 cases with coronary heart disease patients of chronic heart failure at the same period received as study group, they were treated with Shenmai injection based on the treatment of the control group,compared the curative effect between two groups. Results After treatment intervention,the total effective rate of TCM syndrome of the study group is higher than the control group(P<0.05). Left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter (LVEDD), left ventricular systolic diameter(LVESD) of cardiac function improved significantly better than control group(P<0.05); Serum hypersensitive c-reactive protein (hs-CRP),brain natriuretic peptide(BNP),plasma tumor necrosis factor alpha (TNF alpha) levels, compared with before treatment were significantly lower,and decreased significantly than that of control group(P<0.05). Incidence of adverse reactions was no significant difference between groups. Conclusion Shenmai injection and atorvastatin in treating coronary heart disease of chronic heart failure can achieve significant clinical effect and improve the patients' heart function, high safety, worthy of further popularization and application in clinic.
