Objective To investigate the college students′understanding of antimicrobial agents knowledge in two colleges of Huainan and provide a scientific basis to further conduct the health education of rational use of anti -microbial drugs among college students .Methods The antimicrobial perception of 2 college students with 10 differ-ent majors were investigated by cluster-sampled with the questionnaires designed by the authors .Results The correct answer rate of antimicrobial agents knowledge was 61.7%in overall college students ,72.3%in pharmaceutical pro-fessional class students,53.4%in non-medical specialty,and the difference was statistically significant (P<0.01). In lower grade students,the rate was 57.2%and 68.1%in high school students.Also the difference was statistically significant (P<0.01).The rate of students who use antimicrobial drugs without guidance reached 84.1%,the rate in pharmaceutical professional class students (88.6%) was higher than that in non-medical professional class students (80.6%) (P<0.01).Conclusion College students are not sufficiently aware of using antibiotics reasonably and adverse reaction .Consequently ,related publicity and education should be strengthened in various forms to improve lev-el of using antibiotics reasonably among college students .

Objective:To explore the correlation between life events and self-esteem, so as to provide scientific evidence for strengthening the mental health education of rural middle school students. Methods:A survey was conducted among 2489 students(male:1319,female:1170) in two rural middle school of Anhui province by the cluster sampling methods. Self-esteem and life events were assessed with the Self-Esteem Scale (SES) and Adolescent Self-rating Life Events Check List (ASLEC).Results:472 students (19.0) had problems on the self-esteem,15.7 boys and 22.6 girls were low self-esteem.

Objective To investigate the status and influencing factors of knowledge,attitude and practice(KAP) about AIDS among the migrant miners in a nonferrous metal company of Anhui Province and to provide evidence for constituting strategies and measures for AIDS health education and behavioural intervention.Methods 303 migrant miners in a nonferrous metal company were surveyed.Univariate analysis,Logistic regression and correlation analysis were used to explore their influencing factors.Results The general rate of awareness of AIDS was 87.9%,and the main factor affecting miners knowledge level of AIDS was their educational level.Only 55.1% of migrant miners thought people with AIDS should not be isolated;50.8% of them would like to contact people with HIV;38.0% did not object to extramarital sex.There were 32(10.6%) migrant miners admitting having had extramarital sex in the recent three months,but 11(34.4%) admitted never having used condoms,only 7(21.9%) having used each time.Multivariate analysis identified the influencing factors for condom utilization including age and attitude to people with HIV/AIDS.Conclusions ①The migrant miners have sufficient knowledge about AIDS.②The traditional sexual beliefs are changing,and an increasing number of people are tolerant to extramarital sex.Consequently,it is likely that extramarital sex might rise.③The promotion of condom use should be strengthened.

Objective To investigate the clinical therapeutic effect of general spine system(GSS) short-seg-ment posterior fixation for the thoracolumbar spine fracture.Methods Totally 47 patients with thorocalumbar fracture were retrospectively analyzed from May 2006 to July 2009,which were operated by general spine system short-segment posterior fixation,preoperative and postoperative Cobb angle,front and rear margin height ratio of vertebral body and the recovery of neural function were measured respectively.Results All patients were followed up,in 47 patients with thoracolumbar burst fracture,kyphosis deformity were corrected satisfactorily in X-ray visibly,vertebral body height got good recovery.2 cases occurred loss of corrective angle less than 5% after operation,in Frankel function classification.B～D classes showed significant improvement( at least one grade),A grade improved to B in 1 case,no serious complications occurred.Conclusion GSS short-segment posterior fixation was a safe and effective treatment method for thoracolumbar fracture.It can restore height and physiological curve of injuried vertebral body,contribute to recovery on neural function.

Objective To develop the multidimensional sub-health questionnaire of adolescents(MSQA)which is suitable for Chinese adolescents.Methods The original questionnaire was composed of 101 items related to physical and psychological domains and six dimensions.Different statistic methods were taken to do item analysis,reliability and validity evaluation.Results The final MSQA was composed of 71 items.The test-retest correlation coefficient,Cronbach's ? coefficient and split-half reliability coefficient of the questionnaire were 0.868,0.958,0.942,respectively.Taking SCL-90 and CMI as criterion,the criterion-related validity were 0.636,0.649,respectively.The structure of MSQA from factor analysis identified with the original designs.Both of scores and the number of items,which sub-health symptoms lasted for more than one month,on physical,psychological domains and overall questionnaire in first test,were higher than the later one among freshmen.Scores and the number of items for grade one high school students were lower than those of grade three students.Conclusions The MSQA is successfully developed with good reliability and validity coefficient,and can be promoted in large sample population.

Objective To evaluate the effect of behavioral intervention on changing knowledge, attitude and practice (KAP) about AIDS among the migrant workers in railway construction sites. Methods Health education and behavioral intervention on AIDS were carried out among the migrant workers for 4 to 5 months, who were clusteredly sampled from two railway construction sites, in the forms of mini-media, peer education and so on. Questionnaire survey was conducted among them before and after the intervention. Results The results showed that the knowledge awareness of the migrant workers on the transmission routes, preventions of AIDS and self-protection consciousness increased significantly by comparing the indexes of 943 pre-intervention with those of 671 post-intervention workers. After intervention procedures, the rate of those workers who would adopt negative attitudes towards the HIV infected persons because of fear and discrimination was decreased from 9.8% and 10.5% to 6.3% and 3.5% (both P

The early training of scientific research for seven-year medical program students is an important step to foster inventive advanced medicine professionals.According to our department research project,we give the students the medical research lecture and establishing the tutorial system in which the tutors are responsible for guiding students to become a study group,leading them to develop their primary scientific research.The result shows it has good effect on establishing scientific thinking,improving their scientific research ability and raising their awareness of scientific research.

‘Program of teaching quality and teaching reform in institutions of higher education' (‘quality project' for short)is a significant measure to deepen the teaching reform of university and to improve the teaching quality of universities in a new age.The present situation of‘ quality project' system construction was analyzed and the experiences were summed up.Meanwhile the problems of emphasizing project declaring and ignoring educating,emphasizing quantity and despising feature were pointed out and the measures to promote all-round development,distinctive cultivation and coordinated management based on the needs of teachers and students were proposed.All these will future promote the development of ‘quality project' system.
