Research on the development of the concept of death in children and its influencing factors.

In this study, 114 Chinese children aged 5-6 years old in Henan Province and 114 mothers were selected as research subjects, 59 boys, 55 girls, and 114 mothers. Semi-structured interviews were conducted with children to test the development of the concept of death in children. At the same time, a questionnaire survey was conducted among the children's mothers to analyze the influencing factors of the development of children's concept of death. The results of the study showed that children aged 5-6 years had the concept of death, and the sub-components were acquired in a certain order, but the development was not balanced, the overall level of development of the concept of death is slightly higher in girls than in boys; "Whether or not the family talked openly about the topic of death" had a significant effect on the sub-component of the children's concept of death, "Universality of death" (ß = -0.301, t = -2.007, p < 0.05) and "causality of death" (ß = 0.315, t = 2.582, p < 0.05); and "whether or not there was the experience of exposure to death-related events" had a significant effect on "Irreversibility of death" (ß = -0.326, t = -2.36, p < 0.05); Mothers' natural acceptance of death (ß = -0.293, t = -2.209, p < 0.05) and convergence-orientated acceptance (ß = 0.415, t = 2.315, p < 0.05) had significant effects on the "inorganicity of death" of children's concept of death.

Effect of folic acid on plasma homocysteine levels and major cardiovascular events in elderly patients with hypertension / 中国基层医药

Objective To investigate the effect of folic acid on plasma homocysteine(Hcy) levels and major cardiovascular events in elderly patients with H hypertension.Methods 200 elderly patients with H hypertension were randomly divided into the observation group and control group with 100 cases in each group according to the digital list methods,the control group was given health education and routine anti-hypertensive drug for treatment while the observation group was given folic acid on basis of the conventional treatment,the Hcy levels after 3 months of treatment and incidence of major cardiovascular events among 3 years of the two groups were compared.Results (1) The level of plasma Hcy in the observation group decreased significantly after treatment,with statistically significant difference when compared with before treatment (t =12.32,P ＜ 0.05),that in the control group had no obvious change after treatment than before treatment,there was statistically significant difference between the two groups after treatment(t =11.45,P ＞ 0.05);(2) The occurrence of cardiovascular events among 3 year after treatment of the observation group was 6 cases,the incidence rate was 6％,the control group occurred 15 cases,the incidence rate was 15％,the difference in the incidence of the two groups was statistically significant(x2 =8.24,P ＜ 0.05).Conclusion Folic acid intervention can reduce the plasma Hcy levels in elderly patients with H hypertension and control the occurrence of cardiovascular events.
