Objective To provide references for enhancing the connection between the need of society and the training mode of in-service postgraduates who major in health service management by analyzing the existing and potential in-service postgraduates' potential trainingwishes andexpectations.Methods Questionnaire surveys,which involved basic information,motivations and aspirations on the advanced studies,understandings and suggestions on the cultivating mode,were conducted among in-service postgraduates(Grade 2010 through Grade 2012) who major in health service management in BUCM and staffs in the departments of corresponding postgraduates.Data including 128 validated questionnaires were analyzed using descriptive statistics in excel.Results The data indicated that further education was welcomed by 87 in-service postgraduates(85.3％ of the survey samples),who had astrong willing to further study.Specifically,the following tendencies were obtained:interdisciplinary training combining research and practice was approved by 71 in-service postgraduates (55.5％ of the samples); career-oriented talent training mode was accepted by 90 in-service postgraduates(70.2％ of the samples); 79 in-service postgraduates (61.7％ of the samples) believed courses should include both theory and practice educations; flexible educational system was welcomed by 77 in-service postgraduates(60.0％ of the samples) ; 61(47.7％) in-service postgraduates wished to attend class on week-ends while 45 (35.0％) wished to attend class in evenings; group instruction method was recommended by 73(57.0％) in-service postgraduates; 104(81.3％) believed double-tutors system should be applied to academic dissertation,and the academic dissertation could be all kinds of research papers such as investigation report,which was approved by 97 (75.6％) in-service postgraduates.Conclusions Through the above analysis,it can be validated that education on in-service postgraduates who major in health service management is worthy of further development.Finally,colleges and universities are suggested to optimize the training mode in four aspects including training objective,curriculum provi-sion,teaching methods and graduation thesis.

Objective To analyze the relationship between BIDP and breast cancer, and to evaluate the treatment of BIDP. Methods 103 cases of BIDP were studied retrospectively in respect of its clinical and pathological features, diagnosis, and treatment. Results Among the patients, there were 102 women and 1 man. The diagnosis was all verified by pathological examination. The rate of misdiagnosis was high(62.1%). Local excision was performed in 18 patients, regional lobular excision in 62, in nine patients modified radical mastectomy for malignant change in 9 patients, and simple excision for malignancy in 2 patients. The recurrent rate after local excision was 11.7% after 13 years, and the rate of malignant change was 6.8%. Conclusions To sum up the relationship and differentiate method between BIDP and Breast Cancer, and briefly discuss the methods of treatment.

Objective:To study the impact of palatal scar force on the maxilla with unilateral cleft palate by finite element model. Methods:A 3-dimension finite element model of maxilla with cleft palate containing soft tissue was established,the soar force on the maxilla was analyzed by ansys.Results:Cleft area was identified as the center of rotation,cleft side of the maxilla reflected clock-wise rotation and non-cleft side anticlockwise rotation.The maxilla moved from outside to inside in cross section and front to back in the sagittal plane,and the former was greater than the latter.The outside of alveolar process was subjected to stress of mainly drawing force,the inside to stress of mainly compressive force.The deformation of maxilla was mainly in the front-end.Deformation of the alveolar was greater than that of maxilla body.Among deformations of three dimensions,the width was the largest,the length was the smallest,and the height was between both above.Conclusion:Along with the rotation of the maxilla,cleft area becomes gradually smaller.Among the three dimensions,the width is the largest,the length is the smallest and the height is between the both.The af-fect on maxilla is mainly in the front-end.The affect on the alveolar is greater than that on the maxilla body.

BACKGROUND:The two main cages used in anterior cervical surgery are titanium cages and poly(ether-ether-ketone) cages, but it is stil controversial in imaging performances and clinical outcomes.
OBJECTIVE:To systematical y evaluate imaging performances and clinical outcomes between titanium cages and poly(ether-ether-ketone) cages in anterior cervical discectomy and fusion surgery.
METHODS:The Cochrane library (issue 5, 2013), Medline database, EMBASE, CNKI and Wanfang database were retrieved by computer. The deadline of al the retrieves concerning control study of uses of titanium cages and poly(ether-ether-ketone) cages was June 1st, 2013. Two reviewers assessed literatures independently, and the meta-analysis was conducted by RevMan 5.2 software.
RESULTS AND CONCLUSION:A total of four literatures including 235 patients, 128 of titanium cages and 107 of poly(ether-ether-ketone) cages, were included. Meta-analysis results showed that there was no statistical y significant difference between the groups in fusion rates, subsidence and dislocation rates of short-term fol ow-up and clinical outcomes (al P>0.05). There were statistical y significant differences between the groups in subsidence and dislocation rates of long-term fol ow-up (P<0.05). Poly(ether-ether-ketone) cage group was superior to titanium cages group in maintenance of cervical curvature and intervertebral height. This meta-analysis showed that poly(ether-ether-ketone) cages had good fusion rates and clinical outcomes, less subsidence and dislocation rates, and can better maintain cervical curvature and intervertebral height compared with titanium cages.

Objective:To establish a soft tissue 3-dimension(3D)finite element model of human palate.Methods:Based on the intrinsic finite element model of human maxilla,palatal mucoperiosteum flap with the thickness of 3.06 mm was added on the oral side of the plate model by ANSYS software,material property of the soft tissue was loaded,the soft tissue 3D finite element model of the palate was established.Results:By applying finite element method,the established 3D finite element model could reflect biomechani-cal properties of the soft tissue of the palate on computer.Conclusion:The 3D finite element model of the soft tissue of human palate provides the foundation for further study.

AIM:To establish the murine model of oxygen induced retinopathy ( OIR) and to evaluate the inhibition of retinal neovascularization by erythropoietin ( EPO) blockade.
METHODS: Neonates of C57BL/6 mouse ( P7 ) were exposed to 75%±2% oxygen for 5d and return to normal air environment when 12d ( P12 ) to establish oxygen-induced retinal neovascularization model. The neonates were divided into groups, injected with 0. 5μL solution containing 25ng ( group A), 50ng ( group B), 250ng ( group C) of soluble erythropoietin receptor ( EPO-R) or PBS (group D) at P12, P14 and P16 in the right eye. On P17, the litters were sacrificed and their right eyes were enucleated and fixed with 4% paraformaldehyde, made pathological section. The number of breakthrough internal limiting membrane neovascular nuclei was counted with pathological retinal morphology, understanding theproliferative degree of retinal neovascularization.
RESULTS: The pathological sections showed the neovascular cell nuclei which penetrating the inner limiting membrane in intravitreal EPO receptor injection group was reduced statistically than that in PBS injection group, the difference was statistically significant ( P<0.01). And, neovascular nuclei count differences in the
various concentrations of EPO receptor group was statistically significant (P<0. 01). With the EPO receptor concentration increase, neovascular endothelial cells broken through the internal limiting membrane was reduced.
CONCLUSION: Intravitreal injection of soluble EPO receptor can block EPO and improve neovascularization. The new method is expected to become new treatment of ocular neovascular diseases.
