我国养老保障现状分析

目的　综合家庭养老及社会养老情况探讨我国老年养老保障体制的现状及亟待解决的问题。方法　从家庭居住类型分布上探讨老年人得到帮助的来源渠道，以一侧面反映家庭保障状况，从享受退休金和公费医疗方面看社会保障的实行情况，将两方面结合起来对我国城乡老年人的养老现状进行对比分析。结果　家庭养老保障形式在我国占主导地位，社会保障体制覆盖面不足且城乡存在明显差距。结论　我国的社会养老保障机制亟待完善。

The Ageing delaying effects of Chinese herb medicines which possess the properties of Bu Shen Yi Jing on nucleic active genes and RNAase activity of old mice

The effects of Bu Shen Yi Jing medicine on liver nucleic active genes, serum Ribonuclease and blood SOD activities of old mice were studied in order to explore the delaying ageing molecular mechanism of Bu Shen Yi Jing medicine. The results indicate that there are pronounced elevation of digest sensitivity to active gene probe DNAase I of Nuclei and blood SOD activity and decline of serum RNAase in young group vs old group. The Bu Shen Yi Jing medicine can raise the digest activity to DNAase I of liver nuclei and the activity of blood SOD, and decrease the activity of serum RNAase of old mice. It may be one of the delaying ageing molecular mechanisms of Bu Shen Yi Jing medicine that they raise the liver nuclear active genes amount, blood SOD activity and decrease the serum RNAase activity.
