Objective: To study morality and personality of children in single and non-single child family Method:204 children aged 4-14 in single child families were collected 204 children with siblings were sampled matched by age, sex, and education levels of parents and caregivers They composed the matched sample Other 2300 children were also collected in this study including 1626 in single child family and 674 with siblings (random sample) The research instruments included Inventory on Children's Morality, EPQ for children, and Scale of Children's Temperament Parents of children completed these inventory and scales; teachers of children completed the Inventory on Children's Morality Results:In the above two samples, in assessment of morality, parents of single child in family gave lower scores on their children's virtue than parents of multiple children gave on their children But no morality difference was found between single and non-single children when assessed by their teachers In the random sample, more school aged children in single child family had extroversive personality than their counterparts in multiple children family In the matched sample, no difference on introversive-extroversive between single and non-single children was found In both samples, there were more mood-stable and less unstable children in the group of children with siblings; types of Bile-plethora and Bile-melancholic were more frequent in children of single child family Conclusion:Children of single child family are unstable in mood, their morality problems are more obvious in family than in school

The instance reality of medial equipment combined with the center problem of standardization management on medical equipment stock to discuss the questions of how to manage and what about manage.According to correlated management demand and the fact of medical procurement,from the point of view on frame construction flow to the problem of elementary demand on medical equipment procurement,the stock process of medical instrument,the stock process of medical consumable and the management of purchase invoice etc were analyzed.The beneficial research reference can be provided by the daily management jobs of stock and maintenance,the management question of more refinement and general standardization.

The general principles on maintenance and management of technical specification are discussed. Through summarizing many years maintenance experiences of the hospital or medical institutions technical support department, the beneficial mentalities and referential experiences are provided by standardized and effective management on maintenance of medical equipment, according to the medical technology level of medical equipment management department, the economic efficiency, the size of medical equipment, the quality of maintenance technicians, and service ability as well as the management methods of medical equipment material.

There are many kinds of scaffolds used in the field of tissue engineering, which can be divided into natural biological scaffolds and synthetic scaffolds. This paper summarizes the latest advances of research on scaffolds of skin tissue engineering and review amounts of related literatures on this field. The result shows that natural biological scaffolds can provide a better three-dimensional space for the adhesion and generation of cultured cells. These scaffolds have an extensive application in skin tissue engineering.

Military medical equipment develops rapidly in the 10th five-year-plan,but the low utilization rate still widely remains.One of the deep-seated reasons for this problem is the unreasonable element of the establishment system in military medical organization.This paper suggests reforming the military medical organization establishment system boldly,adjusting the existing power of medical service,concentrating the limited manpower & material resource and strengthening the construction of division hospital so as to fully exert the efficiency of medical equipment and improve the ability of medical service support.

Objective To explore the effect of Wuji Solution (He Ji Ju Fang) on excreting IL-8 of SGC-7901 cells infected with Helicobacter pylori (H?pylori) in vitro. Methods H?pylori was inoculated to SGC-7901 cells. ELISA was applied to examine the production of interleukin-8 (IL-8) of cells infected with H?pylori. Results The production of IL-8 of infected cells was lower than that of control group (P

Objective To investigate the clinical significance of noninvasive heart function monitor of diagnosis and therapy of chronic pulmonary heart disease.Methods The PAP and right heart function of exacerbation period and stable period of chronic pulmonary heart disease,and that of normal healthy controls were monitored.T test were used for statistics.Results Compared exacerbation and stable period of chronic pulmonary heart disease with stable period,the RVPS,PAPS,SVR,PVR,RCI,RCRI,the difference was significant(P0.05).Conclusion Noninvasive heart function monitor is a sensitive way to diagnose and to judge therapy effect of chronic pulmonary heart disease.

As quantum dots( QDs),an advanced porduct of nanotechnology,have been widely used in bio-medicine due to their unique photoelectric properties. QD safety evaluation has become a hot area of research. So far,some researchers have expressed concern about the neurotoxic potential of QDs because the central nervous system was confirmed to be one of the target organs. Several studies found that QDs could enter the central nervous system by crossing the blood brain barrier and following neural pathways and produce some neurotoxic effects,such as damaging the structure and function of neural cells and impairing synaptic plasticity. The potential toxicity mechanisms could include oxidative stress,inflammation and change of ion channels.
