A total of 256 medical professionals at the hospitals of different levels were interviewed and requested to complete the relevant questionnaires.The findings revealed that the top five unsatisfied items were growth & development,working conditions,doctor-patient relationship,income and social status.The levels of job satisfaction varied with their specific occupations and technical titles.Around two thirds of them once had the thought of leaving their pre-hospital care posts.

Objective: To raise the all-round informational level through analyzing the necessity of constructing compound medical library.Methods: Through aiming at the fundamental characters of compound medical library,so as to carry out the practices of theoretical researches,the development and optimization of network environments,the integration of informational resources,the enhancement and innovation of information service quality.Results: To provide some helpful references from the traditional to the compound state.Conclusion: Constructing compound medical library by combining the traditional with the digital base is the only way to accelerate the development of medical library.

Objective To investigate effects of volume,distribution and leakage of bone cement in ver- tebroplasty on the adjacent intervertebral bodies using an experimentally calibrated and anatomically accurate fi- nite-element model of elderly L4-L5 vertebral bodies.Methods Computed tomography(CT)scanning was done,at 1 mm intervals,on L4-L5 vertebral bodies of the lumbar spine of an old man cadaver that had no abnormal findings on rnentgenograms.The L4-L5 motion segment data were obtained from the CT scans to establish in computer a three-dimensional finite element model of L4-L5 functional spinal unit(FSU)with the software Ansys 7.0.Compressive load after virtual vertebroplasty on the damaged model,unipedicular and bipedieolar injections and leakage of cement into the intervertebral space,and the resulting endplate and disc stresses of the adjacent vertebral bodies were analyzed in various spatial distributions of the filling material and different loading conditions. An anatomically accurate finite-element model of elderly L4-L5 vertebral bodies was developed.Results The FSU study suggested that changes in stress and strain at adjacent levels were minimal.Furthermore,endplale and disc stresses of the adjacent vertebral bodies were not influenced by bone cement filling volumes or distributions except under bending,whereas asymmetric distribution and leakage of bone cement to the disk increased the stress of adjacent endplates.Conclusion Since asymmetric distribution and significant leakage of cement into the intervertebral space can increase the stresses of endplates of adjacent vertebral bodies and may lead to a fracture, symmetric placement of cement in operation should be achieved and leakage of cement avoided.

Objective:Through statistical analysis the situation of Nanjing General Hospital scientific research articles to be embodied by the international authority retrieval tool,appraises the hospital scientific research level and the academic status,provides the basis for the hospital administratives in the development of medical department and the training of talent aspect. Methods:With the aid of the MEDLINE retrieval method,analyzes all the Nanjing General Hospital scientific research ariticles,the number of articles in Chinese or foreign language and their distributed situation in the domestic and foreign periodicals from 1996 to 2005.Results:The articles embodied in near five-year show increased year by year,especially for the English articles.But the rank from first to fifth periodicals were published in China, and the number of articles in Chinese was beyond it in foreign language. Conclusion:The results show the international communication and the articles in English are value more and more in Nanjing General Hospital.But it is need to increased the number of articles in the external periodicals,especially the periodical be embodied by 《SCI》.They will advance the development the academic status and scientific research level in the hospital.

Objective To reveal and forecast the incidence trend of Brucellosis, in order to provide acientific basis for future intervention and policy-making. Methods Descriptive epidemiological method was used to analyze and statistically describe the distribution of the disease in different times, different locations and different (7.0783/10 million to 13.1257/10 million) and Qingxu ( 1.4811/10 million to 8.5241/10 million) were higher,followed by Yangqu county(0 to 5.8232/10 million), Xiaodian(0.8108/l0 million to 2.4229/10 million) and Jinyuan district ( 0.5329/ 10 million to 1.5896/10 million), and the remaining counties(districts) in the annual There were 223 cases of Brucellosis patients from 2006 to 2009 in Taiyuan. Vocational high risk population was farmers, with a total of 140 cases, accounting for 62.78% of the total number of incidence, followed by students and workers, respectively, 13, 14 cases, accounting for 5.83% and 6.28%, other occupational groups, 56 cases,77.58%;28 cases aged above 60 years, accounting for 12.56%;22 cases aged younger than 19 years, accounting identical in the four years, most cases occurred in spring and summer and showing a clear seasonal high.Conclusions The incidence trend of Brucellosis is on the rise from 2006 to 2009. High risk population is farmer,and the number of younger patients is on the rise, we propose strengthen protection for high risk groups.

To evaluate the automated segmentation algorithm for detection of intra - retinal layers to process images obtained from ultra- high resolution optical coherence tomography ( OCT ) . Graph theory and the shortest path search based on dynamic programming were applied to automatically segment the 8 intra - retinal layers. We experimentally verified the accuracy and reliability of the algorithm. The results showed that the intra-retinal layer boundaries between automated and manual segmentations matched well. The algorithm successfully segmented the intra- retinal layers in glaucoma, high myopia, and retinitis pigmentosa patients. The proposed automatic segmentation for intra-retinal layers provides a promising tool for quantitative analysis in clinical diagnosis and treatment.

Objective To observe Meissner's corpuscles in prepuces of different shapes and ages. Methods The Meissner's corpuscles were detected with immunohistochemical stain in 204 prepuce sam- ples of different shapes and ages (3-59 years),and the density of Meissner's corpuscles in every sample was obtained as well.The difference of Meissner's corpuscle densities between phimosis and redundant pre- puce,and correlation between Meissner's corpuscle densities and ages were analyzed with Chi-square test and linear regression,respectively.Results The density of Meissner's corpuscles in redundant prepuce has begun to increase since infancy and reached the peak at the age about 15 years.No significant difference in densities of Meissner's corpuscles between phimosis and redundant prepuce was observed till the age of 20 years,and then there was a trend of disappearance of Meissner's corpuscles in redundant prepuce.A signifi- cantly negative correlation between the densities of Meissner's corpuscles and ages was revealed in redundant prepuce (r=-0.236,P=0.009),whereas an insignificantly positive correlation between the densities of Meissner's corpuscles and ages was shown in phimosis (r=0.193,P=0.084).Conclusions The den- sities of Meissner's corpuscles in redundant prepuce develop synchronically with genital differentiation and accord with the status of sexual function in adult males.The persistent high level of Meissner's corpuscles in adult phimosis might be a mechanism of physiological compensation.
