ABSTRACT
The construction of "Double First-class" has started a new journey of higher education in China. Scientific, reasonable and objective evaluation on universities is the foundation and important guarantee for the construction of first-class universities. On the basis of introducing the main university evaluation system at home and abroad, the selection of representative Chinese and world university evaluation system for comparative study has strong guiding significance for the establishment of first-class university evaluation system. Under the background of "Double First-Class" construction, based on Chinese characteristics, the author puts forward some thoughts and suggestions on perfecting the university evaluation system in China.
ABSTRACT
Objective To understand the academic atmosphere current situation of graduate students and put forward relevant countermeasures to protect the academic integrity of graduate students.Methods The graduate student'scientific ethics and academic atmosphere construction situation of graduate students in 10 colleges and universities in Chongqing were investigated by questionnaire survey and analyzed.Results Through 1555 questionnaires,it was found that the average investment of time on scientific research in gruduate students was insufficient,the motivation of learning was complicated,and the situation of preventing academic misconduct was serious.Conclusion This study suggests that colleges and universities should establish an academic integrity security system for graduate students,including establishment of academic integrity system and specializing academic integrity supervision institutions,and strengthing academic integrity education.
ABSTRACT
Since the implementation of synergy of medical education, the education of clinical medi-cal postgraduate of academic degree inevitably has faced problems such as the decrease quality of the source of students, unclear training objectives and confused training model, and bad job prospects. Can these problems be solved effectively or not, which is directly related to the coordinated development of clinical medicine professional degree and academic degree. This study analyzes the problems faced by the graduate education of clinical medicine after the synergy of medical education and puts forward the corresponding countermeasures:firstly, to attract excellent clinical medical undergraduates and encourage medical students of related subjects or clinical doctors having working experience to apply for academic degree;secondly, the university, supervisors and graduates need to clear the training target and ensure the quality of graduate education; thirdly, employment guidance should be carried out throughout all the study stage of graduates, and the school should guide the graduates to form correct opinion of employment and to plan their career reasonably.
ABSTRACT
The study was aimed to assess the effect of Klotho gene and sinoatrial node pacing channel gene (HCN4 and HCN2) for studying sick sinus syndrome, with Klotho gene under the interference of Plasmid-mediated short hairpin RNA. Twenty-five C57BL/6J mice were divided into four groups, i. e, plasmid shRNA 24h group, plasmid shRNA 12h group, sodium chloride 24h group and sodium chloride 12h group. Plasmid shRNA 50microL (1microg/microL) and sodium chloride 50microl were respectively injected according to mice vena caudalis into those in plasmid shRNA group and sodium chloride group. After 12h or 24h respectively, all mice were executed and their sinoatrial node tissues were cut. The mRNA of Klotho, HCN4 and HCN2 gene were detected by RT-PCR. The results of RT-PCR showed that Klotho, HCN4 and HCN2 mRNA levels were lower compared with those in sodium chloride 12h group after 12h interference interval. The results indicated that there might be the a certain relationship between Klotho gene and sinoatrial node pacing channel gene.

In recent years, problem of postgraduate academic misconduct has become more and more serious and has caused the attention of majority of educators and academics. In this paper , the con-notation of postgraduate academic misconduct was defined based on academic standards and comparison was made between academic misconduct and academic corruption. Meanwhile , this paper pointed out problems existed in the current postgraduate academic ethnic construction and analyzed main causes of academic misconduct. Finally, this paper introduced the success experiences of Chongqing Medical Uni-versity in preventing postgraduate academic misconduct from the aspects of system construction , propa-ganda and education, supervision in postgraduate training process, strict control of graduate thesis,etc.
ABSTRACT
Curriculum study is a major phase for medical postgraduate education,however,the patterns of the curriculum system are not uniform among domestic medical colleges,not to mention the uniformed patterns for scientific degree and professional degree.Hence,our school has reformed the curriculum system to set up different curriculum systems for both scientific degree and professional degree according to their different educational goals in an aim to improve the quality of education.
ABSTRACT
It introduced the standardized management of graduate students' experimental records. On the basis of experimental records standardization, 3 level inspection system including tutors, departments and graduate school plays a very important role in setting up the good habit, getting more reliable experimental results and preventing the happening of misconduct in scientific research.
ABSTRACT
Objective To prepare the coating of dexamethasone-eluting intravascular stent and observe the features of its delayed release in vitro.Methods Spray painting and dipping coating were used respectively to prepare stent coating,and then high performance liquid chromatography(HPLC)was used to detect the drug loading.The stents prepared by dipping coating were set in a flow of 50 ml PBS buffer at a velocity of 20 ml/min,and 0.5 ml buffer was collected at 6 h and 1,2,4,6,8,10,12,15 d respectively with another 0.5 ml fresh PBS being added immediately.The drug content of the 0.5 ml buffer was detected by HPLC for drug sustained release in vitro.Results The drug loading of stents prepared by spray painting was(24.26?5.23)?g,while that stents prepared by dipping coating for 4 d was(93.15?7.83)?g.Drugs were released slowly and the release rate reached 84% at 15 d.Conclusion The dipping coating-prepared stents have evident effect of sustained release.
