The vetting of senior professional positions in hospitals is related not only to the development of staff members,but also to the quality of the medical service.It is a multiple-stage process,which involves individuals and every department of a hospital,and is associated with a good understanding of policy and professional knowledge.Naturally,the vetting of senior professional position may bring about many new conditions and problems now and then,which pose challenges that need to be perceived and solved in time.The this article focuses on the resolution of the problems that may arise during the vetting process of senior professional positions of a hospital,and proposes suggestions for the improvement of the vetting.
2.Advances in differentiation of human embryonic stem cells into corneal endothelial cells under the mimical microenvironment
Chinese Journal of Experimental Ophthalmology 2015;33(9):844-847
The lack of donor corneal endothelium is a serious impediment to the development of corneal endothelial transplantation,whereas the bioengineered cornea provides an approach to this problem.Functional corneal endothelial cells which differentiated from human embryonic stem cells (ESCs) can,to some extent,relieve the lack of donor corneas,especially for corneal endothelia.At the moment,an optimal way of offering bioengineered-corneal endothelium is to cultivate the corneal endothelial cells in vitro.This is a process of inducing human ESCs to differentiate into neural crest stem cells (NCSCs) and then into corneal endothelial cells in a favorable medium with growth factors and extracellular matrix,which are matched microenvironment of endothelial cells in vitro.However,the inducement condition is still pending and remains for further research.This article reviewed the researching development of bioengineered-corneal endothelium from the effect of microenvironment and the induction of human ESCs.

4.The study of Perception in Body Somatotype and Dietary Behaviors - The Comparative Study between Korean and Chinese College Students -.
Korean Journal of Community Nutrition 2013;18(1):25-44
This study aimed to analyze about the perception in obesity and body somatotype of university students in Korea and in China. This study provides the basic data of nutrition education for university student healthy weight program in China. The subjects were selected 240 university students of Korea and China. Two types of qualitative and quantitative questionnaires were used to analyze the attitude and body somatotype of subjects. The results of this study were as follows: The average BMI of Korean and Chinese male students was 22.3 and 22.5, respectively while the average BMI of Korean and Chinese female students was 19.8 and 19.7, respectively. In the past three years, the weight gain of Chinese students was higher than that of Korean students. Chinese students preferred the overweight body somatotype more compared to the Korean students. The overweight and obese students had more obvious insufficiency in body somatotype perception. The overweight and obese students had higher tendency to 'eat more meat', 'drink carbonated beverages', 'eat convenience food', 'take fast food' and 'drink alcohol' than the normal and low weight group. The major reasons for Korean students to control weight were 'appearance' and 'self confidence', while the major reasons for Chinese students were 'health' and 'employment'. From the results of associative group analysis (AGA), Chinese students had different semantic value of 'obese' than Korean students. Considering of the food transition status in China, it may be necessary to develop more suitable education programs for weight control for Chinese university students.

5.Mechanisms and strategies for targeting drugs to myocardial ischemic regions
Acta Pharmaceutica Sinica 2010;45(7):827-32
The ischemic heart disease has been endangering human health seriously. Although there are many kinds of anti-ischemic drugs, most of them are lacking in tissue specificity, which together with a remarkably reduced blood circulation in the ischemic zone often lead to a quite low drug distribution in the targets. Myocardial ischemia can cause a lot of pathophysiological changes, such as the enhanced permeability of the endothelial cell membrane, the up-regulated expression of various cell adhesion molecules on endothelium, the exposure of intracellular antigenic components, the decrease of pH within the ischemic zone, and so on. To date, some of these changes have been exploited with limited success to gain the passive, active and physicochemical targeting of diagnostic or therapeutic drugs to myocardial ischemic regions. However, more effective delivery strategies are still eagerly needed. Here, we reviewed and discussed the potential targeting-delivery mechanisms and strategies, used or may be used in the future, for myocardial ischemic regions.

Chinese Journal of Clinical Infectious Diseases 2011;4(3):163-167
Objective To investigate the distribution of aminoglycoside modifying enzyme genes (AMEs) and 16S rRNA methylase genes in drug-resistant strains of Pseudomonas aeruginosa. Methods Twenty strains of drug-resistant Pseudomonas aeruginosa were isolated from sputum and wound secretion samples collected from the First People's Hospital of Huai' an in Jiangsu province. Eight AMEs [aac(3)-Ⅰ , aac(3)-Ⅱ, aac(6')-Ⅰb,aac(6')-Ⅱ, ant{2)-Ⅰ ,ant(3)-Ⅰ , ant(4')-Ⅰ , aph(3')-Ⅱb] and 6 16S rRNA methylase genes (armA, rmtA, rmtB, rmtC, rmtD, npmA) were analyzed by PCR and verified by DNA sequencing. Results Out of 20 strains of Pseudomonas aeruginosa, aac(6')-Ⅱ was positive in 8 strains (40.0% ) , ant2- Ⅰ in 8 strains (40.0% ) , aac(3)-Ⅱ in 5 strains (25.0% ) , aac(6')- Ⅰ b in 2 strains (10.0% ) and rmtB in 1 strains (5.0% ) , respectively. The rest 9 genes were not detected. Among 2 strains harboring aac(6')- Ⅰ b, DNA sequencing confirmed that 1 was aac(6')- Ⅰ b (the clssical type) and another was aac(6')- Ⅰ b-cr. Conclusion Gene aac(6')- Ⅰ b-cr exists in drug-resistant Pseudomonas aeruginosa, and it has modifying effect on both aminoglycosides and quinolones.
10.Flexural strength of denture bases repaired with metal wires Comparison among different amounts of metal wires
Chinese Journal of Tissue Engineering Research 2010;14(8):1504-1507
BACKGROUND: Poly methyl methyacrylate (PMMA) has been widely used as a denture base material in dental field for a long time. However, the fracture of acrylic resin dentures is an unresolved problem in prosthodontics. Therefore, how to improve the flexural strength of repaired denture seems to be extremely important. OBJECTIVE: To study the effect of embedding different amounts of metal wires on the flexural strength of repaired denture bases. METHODS: Twenty-five rectangular specimens (50 mm× 30 mm × 2.5 mm) were fabricated using heat-cured acrylic resins and randomly and evenly divided into five groups: A, B, C, D, and E. All specimens were fractured through the use of universal testing machine, and the flexural strengths were tested. Following preparation of fracture surfaces, one to four metal wires were separately embedded in the groups B, C, D, and E. No metal wires were embedded in the group A. All fractured specimens were repaired using self-curing resins. The flexural strengths were measured again using the same testing machine, and the percentages of strength recovery were calculated. RESULTS AND CONCLUSION: After repair, the flexural strengths were obviously reduced (P < 0.01). Compared to group A, the percentages of strength recovery were significantly increased in groups C, D, and E (P < 0.05). There was no significant difference in the percentage of strength recovery among groups C, D, and E (P > 0.05). These results indicate that embedding two to four metal wires can improve the flexural strength of denture bases.
