The Aging Study on Polyethylene Terephthalate with Surface Modification by Water Vapor Plasma

The aging effects of the contact angle and surface energy on polyethylene terephthalate (PET) have been investigated with surface modification by water vapor plasma. The experimental results show that the contact angle of water and PET decreases obviously and surface energy increases. However, with the increase of the aging time, the contact angle and surface energy change back gradually to original state.

Long-Term Animal Feeding Trial of the Refined Konjac Meal Ⅱ. Effects of the Refined Konjac Meal on the Aging of the Brain, Liver, and Cardiovascular Tissue Cells in Rats

Rats of both sexes were fed on a basal feed containing 1% refined konjac meal (RKM) for 18 months and the effects of RKM on the cell aging were observed. A comparable group fed on the basic feed was used as the control. Results obtained demonstrate that the long-term feeding of RKM to rats can delay the course of cell aging of the gliocyte, cadiomyocyte, and the endothelial cell of the large and medium arteriases, hence it is likely to delay the occurrence of arteriosclerosis and improve the functions of the brain, heart and vascular system.

Protein Kinase Activity Changes in the Aging Brain

The aging process in mammals is correlated with changes in psychomotor performance, cognitive function, and ability to adapt to stress (Montgomery et al., 1982; Lorens et al., 1990). These changes may be related to alterations in neuronal tissue that occur during the aging process. The normal aging process may be conceived of as the neuronal cell’s increasing inability to maintain normal cellular function which ultimately results in a number of morphological and biochemical changes. Morphologically, there is a loss of neuronal cells with increasing age (Brizzee and

Role orientation of the government in the development of the aging industry in the perspective of welfare pluralism theory

Welfare pluralism is in recent years research society of the new policy paradigm, advocate to break me government monopoly, by many subjects together to provide social welfare. Currently, there are offside, absence, not in place and other phenomena in the important subject of government in the development of aging industry, and to solve this problem, must clarify the government＇s role positioning, reasonable and effective government to play a role, so as to promote the development and perfection of the aging industry.

Research on Pension Insurance System under the Background of Aging

With the rapid development of economy in our country, the level of science and technology innovation, all of these prolong the life span of our life. Thus an aging population are increasingly highlight, which are deeply and widely influenced our society, economy, life and other aspects. As the basic insurance which maintain the elderly＇s life quality after they retired, Pension insurance will promove social stability and development. How to reform Pension insurance under the background of the aging of the population will get more and more attention from people. This article starts with the concept of the aging of the population and its development trend. Next, the article analyses the problems of Pension Insurance under the background of the aging of the population. Last, the article summarizes countermeasures according to solve these matters.

The testosterone mimetic properties of icariin

Aim： To evaluate the testosterone mimetic properties of icariin. Methods： Forty-eight healthy male Sprague-Dawley rats at the age of 15 months were randomly divided into four groups with 12 rats each： the control group （C）, the model group （M）, the icariin group （ICA） and the testosterone group （T）. The reproductive system was damaged by cyclophosphamide （intraperitoneal injection, 20 mg/kg·day） for 5 consecutive days for groups M, ICA and T, at the sixth day, ICA （gastric gavage, 200 mg/kg·day） for the ICA group and sterandryl （subcutaneous injection, 5 rag/rat.day） for the T group for 7 consecutive days, respectively. The levels of serum testosterone, luteinizing hormone （LH）, follicle stimulating hormone （FSH）, serum bone Gla-protein （BGP） and tartrate-resistant acid phosphatase activity in serum （StrACP） were determined. The histological changes of the testis and the penis were observed by microscope with hematoxylin-eosin （HE） staining and terminal deoxynucleotidyl transferase biotin-dUTP-X nick end labeling （TUNEL）, respectively. Results： （1） Icariin improved the condition of reproductive organs and increased the circulating levels of testosterone. （2） Icariin treatment also improved the steady-state serum BGP and might have promoted bone formation. At the same time, it decreased the serum levels of StrACP and might have reduced the bone resorption. （3） Icarrin suppressed the extent of apoptosis of penile cavernosal smooth muscle cells. Conclusion： Icariin has testosterone mimetic properties and has therapeutic potential in the management of hypoandrogenism.

Research on the Improvement Path of the Mental Health of the Elderly From the Perspective of College Students’Volunteer Service Activities

The elderly are the main objects of college students’volunteer service activities.At present,there are various forms of college students’volunteer service activities,which are highly valued by colleges and universities and popular among college students.In order to further improve the mental health of the elderly,it could be achieved through paths like strengthening volunteering cooperation with aged services agencies,implementing the volunteer service mechanism of“one person-one file,one person-one policy”for the elderly,establishing a mental health mentor system for volunteer service activities,improving the mental health knowledge level of college student volunteers,carrying out a series of voluntary service activities with the theme of mental health,attaching importance on cultivating the positive and optimistic attitude of the elderly in volunteer service activities,and launching volunteer service activities to enrich the spiritual and cultural life of the elderly.
