ObjectiveTo evaluate the sufficiency of dialysis and nutri ti onal status of 44 end-stage renal disease (ESRD) with urea metabolic parameters such as TACurea,KT/V and PCR.MethodClinical data were collecte d and analyzed with statistic methods.ResultsTACurea and PCR w ere significantly lower in patients in insufficient dialysis group than those in sufficient dialysis group.There was no statistical difference between the two g roups in terms of KT/V.PCR was not influenced by KT/V in sufficient dialysis gro up,while it was significantly influenced by KT/V in insufficient dialysis group. ConclusionTACurea and PCR are significant indicators to assess whether the blood dialysis is sufficient or not in the long run.KT/V can direct ly indicate the effectiveness of single dialysis.Therefore,it is the best indica tor for adjusting the dialytic strategy.However,it is not important if the dialy sis is not sufficient.

Infantile neuroaxonal dystrophy (INAD) is a rare autosome-recessive disease characterized by progressive motor and cognitive regression.The PLA2G6 gene is its causative gene,which encodes calcium-independent phospholipase A2 enzyme (iPLA2-VIA).The diagnosis of INAD is difficult because of its clinical heterogeneity,and the rate of misdiagnosis is high.The purpose of this study is to describe the clinical characteristics,molecular genetics,treatment and prognosis of INAD to improve the acknowledgement of INAD in medical workers and to help make an early diagnosis of INAD.

Objective To establish a stable experimental model of vascularized composite allograft (VCA),which would facilitate us to study of the reaction and intervening measure regarding rejection reaction in the future.Methods From September,2016 to July,2017,30 healthy male New Zealand rabbits,weighted 2.5-3.0 kg each,were chosen.Their ears should be intact without defect or necrosis.All of them were randomly and eaqually divided into 2 groups:transverse amputated group and V-shaped amputated group.In situ ear replantation after the amputation was performed.Histology analysis of skin and cartilage were done through HE and TUNEL staining,in order to compare vital rate of these ears.Results Thirty rabbits underwent ear replantation,including 13 via transverse incision and 17 via V-shaped incision.In transverse group,no ear survived,and some of them encountered vein crisis gradually after operation.The survival time ranged from 1 day to 10 days.There were 2 ears survived in V-shaped group.From HE staining,it was found certain vacuolar degenerated cells within skin and cartilage in failure ears.The rates of cell necrosis and apoptosis were higher than the survived ears.Conclusion Rabbit ear replantation model is viable.However,the rabbit ear replantation model is not suitable to be used in large samples.

Objective:To explore how to enhance the strength of science and technology of research-oriented hospital using goal management, thereby effectively promoting the construction and development of research hospitals.Methods:This paper studies the goal management measures and their effectiveness through data analysis, analyzes the problems of scientific research, goal management measures and changes in scientific research before and after the implementation measures over the years.Results:The goal management significantly enhances the scientific and technological strength. Total amount of research funding kept increasing year by year. Goal accountability management effectively improve the participation in individual scientific research activities. The implementation of high-quality papers goal management has a significant role in promoting the researchers to publish their achievements in domestic journals with international influence.Conclusions:Goal management plays an important role in the improvement of the scientific and technological strength of the hospital, which can effectively promote the construction and development of the research-oriented hospitals connotation. Goal management can serve as a powerful grasper for the research-oriented hospital to improve the scientific research capacity.
