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.

Based on the comparison of medical humanistic education among The Mainland,Hong Kong and Taiwan,this article arrives at the conclusion that the gap in the field of humanity education in the Mainland is one of the important reasons that cause the ever-tenser physician-patient relationship in nowadays.So we propose the countermeasures actively.By increasing the humanity courses,changing the teaching method,reinforcing the construction of talented staff in humanity,creating the environment for the humanity education and so on,we reinforce humanity quality of medical students in order to improve our medical education.

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 assess the renal cortical perfusion parameters by the imaging of computed tomography (CT) in patients of essential hypertension (EH) with target organ damage.
Methods: A total of 90 subjects with the entire information including 59 EH patients were studied. The EH patients were divided into 2 groups: EH + target organ damage group,n=30 and EH without target organ damage group,n=29. In addition, there was a Control group,n=31 healthy volunteers. All subjects received 128-slice dual-source CT renal perfusion scanning, the quantitative perfusion of renal cortex blood lfow (BF), blood volume (BV), time to peak (TTP) and the mean transit time (MTT) were examined and compared among different groups.
Results: There were 90/97 (92.8%) participants eligible for perfusion analysis. Compared to Control group, EH without target organ damage group had the similar parameters of BF, BV, MTT and TTP,P>0.05. While EH + target organ damage group had decreased BF (214.6 ± 36.1) ml/(min?100 ml ) than Control group (262.1 ± 26.6) ml/(min?100 ml ),P<0.01, and BV, TTP, MTT were similar to Control group,P>0.05. Compared to EH without target organ damage group, the EH + target organ damage group presented decreased BF (214.6 ±3 6.1) ml/(min?100 ml ) vs (268.9 ± 33.1) ml/(min?100 ml ), P<0.01 and prolonged MTT, TTP,P< 0.05.
Conclusion: CT imaging may evaluate the renal cortical perfusion changes, and especially BF which can relfect the renal perfusion more sensitively than other parameters in EH + target organ damage patients.

Objective: To explore the features of ascending aortic distensibility (AAD) and risk factors in pre-hypertension (PHT) patients. Methods: A total of 206 participants who received retrospective ECG-triggered coronary CTA by physical check-up or by clinically suspected coronary artery disease (CTA) were enrolled. The participants were divided into 2 groups: Control group, the subjects with normal blood pressure,n=85 and Pre-hypertension group,n=121. A 128 slice dual-source CT scanner was used and the image was automatically reconstructed at every 5% absolute phases in entire R-R interval. The beginning of left coronary artery plane was deifned as the reference and 25 mm above the reference plane was deifned as interested region. ADD value was calculated. Results: Compared with Control group, Pre-hypertension group had decreased AAD,P<0.01 and similar normalized cross-sectional area (Ss),P>0.05; ADD value was similar among different gender and blood lipid levels. Correlation analysis presented that AAD was negatively related to age (r=-0.69,P=0.001), systolic blood pressure (r=-0.37,P=0.001), pulse pressure(r=-0.43,P=0.001) and glycosylated hemoglobin (r=-0.43,P<0.05). Age and systolic blood pressure were the independent risk factors for AAD decline (standardized β=-0.66,P=0.001) and (standardized β=-0.44,P=0.001). Conclusion: Without additional contrast media consumption and radiation dosage, retrospective ECG-triggered coronary CTA may detect AAD changes with risk factors at the early stage in pre-hypertension patients which is helpful to distinguish the high risk individuals.

Objective To explore the sleep characteristics in first-episode schizophrenics and the effects of olanzapine on body weight and sleep-breathing disorder.Methods 36 first-episode schizophrenics (patient group) and 33 normal controls (control group) were tested with polysomnography(PSG),and compared the difference of PSG,sleep-breathing index and body mass index(BMI) before and after treatment in patient group.Results Before treatment,compared with control group,the patient group had significantly prolonged sleep latency((83.64± 10.62) min vs (29.41 ± 10.05) min),shortened total sleep time ((286.43 ± 17.04) min vs (343.66 ± 16.38)min),decreased sleep efficiency((65.73 ±11.47) vs (86.13 ± 8.15)),increased awake time and arousal number((65.70 ± 10.33) min vs (25.93 ± 9.60) min ; (38.26 ± 6.88) vs (14.40 ± 2.72)) in sleep continuity ; and increased N1 stage ((87.43 ± 11.35) min vs (36.55 ± 6.40) min),decreased N2,N3 stage ((100.53 ± 10.42)minvs (143.35±13.52)min;(49.83±7.51)minvs (87.52±9.74)min) in sleep structure (P ＜ 0.05).After treatment,sleep continuity and sleep structure in patient group were improved,compared with control group,only BMI,arousal index and hypopnea index had statistic difference (P ＜ 0.05).Conclusion The first-episode schizophrenics have both sleep continuity and sleep structure deficits.Although olanzapine treatment can improve sleep quality,long-term use of it may cause overweight and sleep-breathing disorder.
