Objective To study the effect of testosterone on skeletal muscle atrophy of rats induced by dexamethasone,and to explore the relationship between androgen and ubiquitin ligase expression in skeletal muscle.Methods Forty female SD rats were randomly divided into four group:control group(CON),dexamethasone group(DEX),testosterone group(TES)and testosterone plus dexamethasone group(TES+DEX).Blood samples were collected from the abdominal aorta and then centrifuged.The supernatant was collected and stored at-20℃.Gastrocnemius was removed and stored at-80℃.The cross-sectional area(CSA)of muscle fiber was determined by microscopic images of digitized muscle sections,using a computer-based imaging processing system.The expression of muscle atrophy F-box(MAFbx)and muscle RING finger-1(MuRF1)mRNA in skeletal muscle was determined by real-time PCR.The expression of testosterone protein in serum was determined by immunoradiometry.Results Dexamethasone increased the expression of MAFbx and MuRF1 mRNA in skeletal muscle(P

With the public hospitals expanding,the nurses at age of marriage or bearing are enrolled and account for large part of all health care workers in China.A significant percentage of nurses in the period of pregnancy or lactation,especially abortion and sterility,deteriorate the shortage of nursing human resources and the nurses' health.It is essential to cope with the matter in order to maintain the nurses and contribute to the professional development.In this paper,we review the human resource management of the nurses during the periods at home and abroad from the human resources,occupational protection and management approaches,which is contributed to supplement the human resource.

Objective To observe the effect of cigarette smoking on cutaneous wound healing in rats.Methods Healthy adult SD rats,weight 200-250 g,were randomly divided into 4 groups:control group (group C),low tar content group (group L),middle tar content group (group M) and high tar content group (group H),ten rats each group.4 full thickness dermal excision wound models with the diameter of 2.0 cm were established on the back of 40 healthy male or female SD rats.The wound spacing was greater than 2 cm.Group C did not do any intervention treatment,Groups L,M and H rats were put,respectively,into homemade smoke box in 0.1,0.5,and 0.8 mg different-grade tar content of cigarettes and smoked,and the time of wound healing was observed.The wound granulation tissue was taken in 3 and 7 days after surgery.The expression of CD68+ macrophages was detected by immunohistochemical method.The wound healing rate was observed on the days 7 and 16.Results Compared with group C,wound healing time in groups L,M and H was extended (P< 0.05).Immunohistochemical results showed that macrophage numbers in groups L,M and H wound were significantly less than that of group C.The wound healing rates 7 days and 16 days after surgery in the three group smoked were significantly lower than that of group C.Conclusions Cigarette smoking leads to wound healing delay,and wound healing rate is reduced at fixed time point,with the decrease in the number of macrophages.

A comprehensive analysis was carried out about the influencing factors of medication safety in the elderly with multiple chronic diseases,who lived in the community and stayed at their own homes.Applicable and simple preventive countermeasures should be established to ensure the medication safety outside medical agency.We should promote extending service of hospitals,cooperate with community and nursing facility in order to increase life quality of the elderly,and supply reference for professional continuous service model including rapid aging,empty nest with advanced age,disability and dementia and elderly people with chronic diseases.

Objective To investigate the fatigue experience of the community-dwelling frail elderly to establish the conceptual model.Methods Grounded theory was adopted.With MAXQDA v10.4.15.1for 3 levels coding,the conceptual model of fatigue experience of community-dwelling frail elderly people was structured through constant comparison and in-depth analysis.Results Multi-response,selfmanagement,safe and belonging,hitting rock bottom,accepting and transferring formed the conceptual model.Conclusions Based on the conceptual model,nurses should pay more attention to concern about the fatigue experience of community-dwelling frail elderly people,and probe different assessment methods to enrich comprehensive geriatric assessment (CGA),then improve the community health service level and the quality of elderly people's life.

Objective To explore the opportunities and challenges which COC (continuity of care) has been facing,some strategies were proposed and improved continuously during the process of deepening medical reform in public hospital,and at the same time to supply reference for government to make relative policy.Methods By SWOT-analysis,the strengths,weaknesses,opportunities as well as threats of COC in medical reform were analyzed comprehensively.Results Depending on national relevant policies,supportive measures,the cooperation from multidisciplinary team was improved.Along with strategies of strengthening advantages,weakening disadvantages,meeting challenges and facing up to threat.COC had be approved and consented initially.Conclusions Public hospitals should demonstrate their various resources and make full use of their advantages,then guide and solid grass-roots in the new healthcare system which integrate medical,rehabilitation and elderly nursing out of the hospital.It must benefit the hospital,specialized subject,family and society.

In this paper is proposed a new method for functional connectivity detection using regression analysis. First, the resting state functional magnetic resonance imaging (fMRI) data from each voxel is passed through a bandpass filter to obtain frequencies between 0.01 Hz and 0.1 Hz. Then, the region of interest (ROI) is defined and the mean time course of all voxels in ROI is used as a regressor. Finally, the linear relationship between the time course of other voxels and the regressor in the resting brain is estimated. By the application of this new method in simulation data and fMRI data, the relevant validity and reliability are demonstrated.
