Nowadays,with the ever-tenser physician-patient relationship,construction of medical professionalism has turned out to be a heated topic.This essay tries to explore the construction of medical professionalism from the perspective of cultivating a humanistic culture among medical students.Based on the comparison of medical humanistic education between China and Britain,this article arrives at the conclusion that defective humanistic education is one of important reasons that cause the inadequacy of medical professionalism among Chinese physicians,and points out some effectual measures to improve the medical professionalism in our country by the inspiration from our British counterparts.

OBJECTIVE To investigate the pre-operation and/or pre-transfusion testing on patients to avoid risk of(occupational) infection exposure among medical staff and its significance in prevention of nosocomial infection.METHODS Serum hepatitis B(virus surface) antigen(HBsAg),antibody against hepatitis C virus(anti-HCV),(antibody) against human(immunodeficiency) virus(anti-HIV) and toluidine red unheatedserum test(TRUST) were performed on samples from 10 745 cases of pre-operation and/or pre-transfusion from 2003 to 2004.RESULTS The number and(percentage) of positive reaction for HBsAg,anti-HCV,anti-HIV and TRUST were 1163,(10.81%);21,0.20%;1,0.01%(confirmed by HIV Reference Laboratory,Center for Disease Prevention and(Control) of Zhejiang Province) and 74,(0.69%),respectively.TRUST positivity was further confirmed with TPHA.(Overlapping) infections were mostly observed between HBV and HCV,or,to a less scale,between HBV and syphilis.For HBV infection the(department) of digestive medicine was prevalent(?~2=4.77,P

Objective To explore the effects and molecular mechanisms of arsenic trioxide(As 2O 3) in inducing apoptosis of colonic cancer cell line SW480. Methods The morphologic changes and apoptotic rate of SW480 cells induced by As 2O 3 were observed with fluorescent microscopy and flow cytometry. The bcl-2 and Fas expressions induced by As 2O 3 in SW480 cells were examined by immunohistochemical method. Results 24 hours after exposed to As 2O 3, SW480 cells exhibited typical morphologic changes of apoptosis, the apoptotic rate of which was 2.1%～10.6%. A typical subdiploid peak before G 1 phase was observed by flow cytometry, and As 2O 3 mainly acted in G 2/M phase. As 2O 3 decreased bcl-2 expression and increased Fas expression in SW480 cells. Conclusion As 2O 3 could induce apoptosis of SW480 cells. The molecular mechanism of As 2O 3-induced apoptosis of SW480 cells might be down-regulating the bcl-2 expression and up-regulating the Fas expression.

Objective To compare the effects of typical and atypical antipsychotics treatment on P50 sensory ga-ting in first-episode schizophrenics.Methods Using conditioning-testing stimulus paradigm and stimulus train paradigm to record the P50 auditory evoked potential in 36 normal controls and in 61 first-episode schizophrenics before and after treat-ment.Patients were categorized into two groups:the typical antipsychotic treatment group(typical group)and the atypical antipsychotic treatment group(atypical group).Results Before treatment,both of the typical and atypical groups had low-er levels of S2-P50 amplitude,P50 suppression in conditioning-testing stimulus paradigm and P50 amplitude as well as P50 suppression evoked by high frequency stimuli in stimulus train paradigm in comparison with controls(P<0.05).After treatment,the typical antipsychotic treatment significantly improved the levels of P50 suppression in the stimulus train para-digm but not the levels of S2-P50 amplitude,P50 suppression in the conditioning-testing stimulus paradigm(P<0.05)whereas the atypical antipsychotic treatment improve the levels of P50 amplitude,P50 suppression in both stimulus train paradigm and the conditioning-testing stimulus paradigm(P<0.05). Conclusions The typical antipsychotic treatment can ameliorate the P50 suppression in stimulus train paradigm,but not in the conditioning-testing stimulus paradigm,whereas atypical antipsychotic treatment can ameliorate P50 suppression in both paradigms.

Objective To compare the effects of atypical antipsyehoties treatment on PS0 sensory gating in first-episode schizophrenics. Methods The P50 auditory evoked potential was recorded by using conditioning-testing stimulus paradigm and stimulus train paradigm in 36 normal controls and 53 first-episode schizophrenics be-fore and after treatment,and compare the difference of P50 sensory gating after treatment. Results Before treat-ment, compared with control group, the atypical groups both had statistic difference of T-P50 amplitude ((1.01±0.88)μV, (0.68±0.64)μV, (0.58±0.47)μV), P50 suppression ((0.61±0.27), (0.54±0.22, (0. 59± 0.19)) in conditioning-testing stimulus paradigm and P50 amplitude,P50 suppression evoked by high frequency stimuli in stimulus train paradigm(P < 0.05), but no difference among the atypical groups (P > 0.05). After treat-ment,compared with control group, there was no statistic difference in olanzapine and elozapine groups of T-P50 amplitude and P50 suppression in conditioning-testing stimulus paradigm, but the difference in risperidone and que-tiapine groups still obviously(P<0.05). In stimulus train paradigm, there was no statistic difference of P50 ampli-tude, P50 suppression evoked by high frequency stimuli in every groups (P>0.05). Compared within atypical groups, the difference of P50 amplitude and P50 suppression were both obviously(P<0.05). Conclusion Each a-typical antipsychotic has different effect on P50 sensory gating;and the conditioning-testing stimulus paradigm and stimulus train paradigm P50 sensory gating may reflect different central neuron mechanism.
