Objective: To evaluate the satisfaction degree of non-medical students in medical school,and to investigate the factors that influence satisfaction degree. Method: Selfcompile scale is administered to 430 nonmedical students from 6 medical colleges,in which 5 is in Guangdong province and 1 is in Ha’erbin city. Result:The satisfaction of nonmedical students is low,significant diferences are found between grades,and between students with medicine as the first choice major and those whose first choice major is not medicine. Conclusion:Medical colleges should pay more attention to nonmedical majors,improve the quality of teaching,and so on in order to improve the nonmedical students’satisfaction degree.

OBJECTIVE： To find out the change of drug resistance of Shigella shigae in our hospital during recent five years.METHODS： To collect the stool of suspectable cases of clinical bacillary dysentery and to carry out bacterial culture and drug sensitive test.RESULTS： The resistance rates of Shingella shigae to ampicillin and fluoroquinolones raised obviously， but the bacilli were still sensitive to amikacine and cefobid.CONCLUSION： It is important to strictly control the indications in using antibiotics and to prevent the emergence of drug resistance of bacteria.

The scar tissue, resulting from aberrant process of wound healing , can bring about cosmetic deformeties and func-tional limitation, even the displacement of tissues and organs .The widely use of autologous fat graft in regenerative medicine offers a relatively new option for scar treatment .Lipofilling has improved symptoms and appearance of scars in several studies .The application , therapeutic effect and mechanism research of autologous fat graft for scar treatment are summarized in this paper .

Objective To evaluate the platelet function in the patients with recurrent spontaneous abortion (RSA) ,to explore the correlations between Hcy and folic acid(FA)with mean platelet volume(MPV) and platelet distribution width(PDW) ,and to evalu-ate the application value of above indicators in predicting RSA .Methods Twenty-eight cases of RSA ,40 cases of healthy pregnancy and 50 healthy child-bearing women(control group) in our hospital were selected .The detection indicators included peripheral blood Hcy ,FA ,PLT ,MPV and PDW .Results The PLT and FA levels in the patients group were significantly lower compared with the normal pregnancy group and control group(P<0 .01) ,while the Hcy ,PDW and MPV were increased(P<0 .05);the various indica-tors had no statistically significant difference between the normal pregnancy group and control group (P>0 .05) .Blood Hcy was negatively correlated with PLT and FA ;Hcy and FA were negatively correlated in the normal pregnancy group ,other indicators had no obvious correlation(P>0 .05) .Conclusion The Hcy metabolism abnormality ,platelet parameter changes and their interactions may be related to RSA .The combined detection of Hcy ,FA and platelet parameters has a certain clinical significance to early diag-nosis and treatment of RSA .

Objective:to study perspective of college students on counseling and psychotherapy Method:440 college students were asked to fill up a mental health knowledge questionnaire made by the authors Result:most of college students attached importance to and had a positive attitude towards counseling and psychotherapy, however they misunderstood some concepts and were not satisfied with the service available Conclusion:counseling and psychotherapy are in the early development stage in China

Objective:To investigate college students' perspective of mental health Method:440 college students were asked to fill up SCL-90 and a mental health knowledge investigation questionnaire made by the authors Result:Most students concerned about their mental health and liked to learn the knowledge of mental health However, there were still some aspects they kept incorrect ideas The results also showed that there were some difference in the attitude toward mental health, as well as the comprehension of the knowledge of mental health between male and female; among freshman, sophomore, junior and senior; between students in different universities, and between students who had visited counselors or psychotherapists and others who had not Conclusion:Pearson correlation analysis showed that college students' knowledge of and attitude to mental health related to their status of mental heath significantly

Objective To study clinical efficacy of ganciclovir in the therapy of infectious mononucleosis in adults.Methods 66 adults with infectious mononucleosis in a hospital from January 2010 to December 2014 were studied retrospectively,according to drug therapy,patients were divided into ganciclovir therapy group(n=31)and symptomatic therapy group(n=35),clinical features before therapy,therapeutic efficacy,and Epstein-Barr virus(EBV)DNA negative conversion time were analyzed.Results The time of defervescence,sore throat improvement,EBV-DNA negative conversion,subside of enlarged lymph node,and transaminase recovery in ganciclovir therapy group were all shorter than symptomatic therapy group(all P<0.05).Blood routine recovery time between two groups was not significantly different(P>0.05).Conclusion Ganciclovir has a good antiviral effect on the therapy of adult infectious mononucleosis,it can rapidly relieve patients from clinical symptoms including fever,sore throat and so on.

To study the possibility of enhancing IFN ? level in the lung of rats by gene transfection. The recombined IFN ? expression vector in eukaryotic cell was constructed, and it was transfected into lungs of immunocompromised rats. The expression of pLXSN IFN and pLXSN in the genomic DNA of the transfected cells was investigated, and the level and activity of IFN ? in the BALF and sera was assessed. The results showed that the sequence of the IFN ? gene in the constructed recombinant pLXSN IFN eukaryotic cell was the same as that of the IFN ? of rats found in the Gene Bank. The band of transfected plasmid was found when the eletrophoresis analysis of PCR product of genomic DNA of the transfected cells in BALF was done. It could still be the found 21 days after transfection. The level and activity of IFN ? in the BALF of the transfected pLXSN IFN group were markedly higher than those of transfected pLXSN group.On the other hand, the level and activity of IFN ? in sera showed no difference between the two groups. It was suggested that the constructed recombinant IFN ? exprossion vector in eukaryotic cell could be transfected into the cells of the lungs of rats successfully, inserted into the genomic DNA, resulting in active secretion of IFN ?, and prolongation of its expression.

Objective:To explore some neuroelectrophysiological bases underlying the aggression and violence in male delinquents. Methods:47 male delinquents with official records of aggressive and violent violation and 41 normal controls were examined by resting EEG, brain evoked potentials. Results:No EEG abnormality was detected in the two groups. Compared with the normals, the male delinquents displayed prolonged V latency in auditory brainstem evoked potentials (5.8?0.1/5.5?0.1, F=9.803, P

Objective To investigate the relationship between the cerebral blood flow filling condition and prognosis of patients with acute severe cerebral infarction.Methods The clinical data and MR features of 10 cases of acute severe cerebral infarction were retrospectively analyzed.Results The regional cerebral blood flow(rCBF) and regional cerebral blood volume(rCBV) of 9 cases(90%) in the infarcted side decreased significantly.The reduced percents of the infarcted side reached 64.1% and 49.7% respectively.There were significant differences between two opposite sides(P=0.001,P=0.01).The MRA results showed great vessels(arteria carotis interna or arteria cerebri media) in the infarcted side were all obliterated in the all patients,and simultaneous great vessels in opposite side were narrow or occlusion in 7 cases(70%).2 cases died;and 8 cases were serious disability.Conclusions The cerebral blood flow filling of the acute severe cerebral infarction patients decrease significantly.The prognosis of the patients is quite bad.
