As important Internet users, college students need to establish good cyber ethics to promote healthy development of the Internet and meet the needs of their own growth. The characteristics of college students' cyber ethics include hierarchy, self-discipline, orientation and particularity. Self-respect and respect for others;hon-est and trustworthy;fair and mutual benefit;attention to public welfare and participation;patriotic, studious, cre-ate a harmonious network should be college students' network moral norms.

Objective:To investigate the current situation of network ethics among the college students , to pro-vide evidence for cultivating correct network ethics .Methods:A survey was conducted in 1200 students with a self-designed questionnaire .Results:College students in the network ethics exist conflicts .They eager to trust but face a crisis of confidence , tool enhancements but responsibility fall , network security but network open , virtual but reality.Conclusion:The government should strengthen the network legislation and network credit system , should increase the development of network security technology so as to build networks ethical norms .Colleges should pay attention to culture the social responsibility , and promote the quality level of network ethics among the college students .

Based on practice of video-cases teaching,this paper put forwards four sorts of contradictions,which are the contradiction between time limitation of classroom and expressing limi-tation of video cases,the contradiction between relative independence of video cases (part)and con-sistency of teaching objective (entirety),the contradiction between apparentness of video cases (phe-nomenon)and depth of teaching content (essence)and the contradiction between variability of video case class and control of class by teachers. This paper suggested teaching principle of part conforming to entirety. Meanwhile,it indicated that classroom video case teaching should have strict design, closely coordinated class discussion and teachers should be good at guiding and summarizing. Through these efforts,the above four contradictions can be resolved and designed video case teaching obtained good effect.

Objective To study the relationship among depression associated type 2 deabetes mellitus (T2DM) and personality and quality of life.Methods A total of 246 cases of hospitalized T2DM patients were investigated by schedule tables:self-rating depression scale (SDS),Eysenck personality questionaire (EPQ) and adjusted diabetes-specific quality of life scale (A-DQOL).According to the results of SDS,patients were divided into depression group (171 cases) and non-depression group (75 cases).Correlation analysis and regression analysis were carried out for the collected data.Results There were differences in satisfaction,influence,anxiety Ⅰ,anxiety Ⅱ,neuroticism and extraversion between the two groups(P ＜ 0.05 or P ＜ 0.01).Depression extents was related to the quality of life,neuroticism,extraversion and course(r =-0.243-0.392,P ＜ 0.05 or P ＜ 0.01).Anxiety Ⅱ,satisfaction and course enter the regression equation of depression (β =-0.205-0.322,P ＜ 0.05 or P ＜ 0.01).Conclsion Anxiety Ⅱ,satisfaction and course are key factors inducing depression in T2DM.Neuroticism and extroversion may be the predisposing personality characteristics in T2DM patients with depression.In clinical work,it is helpful for treatment by changing personality and mood of patients.

Objective To evaluate the dynamic contrast-enhanced MRI (DCE-MRI)in detecting experimentally induced testicular ischemia. Methods Thirty healthy male New Zealand rabbits were randomly assigned into 6 groups. There were 5 rabbits in each of the following experimental groups: ( 1 ) Normal control, (2) Sham-operated, (3) ischemia of 3 h group, (4) ischemia of 6 h group, (5) ischemia of 12 h group, (6) ischemia of 24 h group. In all experiment groups, the right testis served as the internal control while the left testis served as the experimental side. DCE-MRI for each animal lasts about 10 minutes. Signal enhanced ratios (SERs) of ROI for both sides of each group were calculated by a computer, and parameters of SERs of 30 s, 75 s, 120 s and maximal SER were used for statistical analysis.Time intensity curves (TICs) were made for two sides of each group via Excel 2003 software and classified into 4 types. Statistical analysis was performed to compare the differences of SERs between left and right testis by two independent Kolmogorov-Smirnov test. Results In group I and 2, significant enhancement was observed on both testes of 10 rabbits. The enhancement decreased gradually with the elongation of ischemia in torsion groups. Three cases of type Ⅰ and 2 cases of type Ⅱ were observed in group 1,5 cases of type Ⅰ in group two, 2 cases of type Ⅰ and 3 cases of type Ⅱ b in group three, 2 cases of type Ⅰ and 2 cases of type Ⅱ b in group four, 5 cases of type Ⅱ b in group five and 5 cases of type Ⅲ in group six were noticed in the left testes. And in TICs of right testes, all cases showed TICs of type Ⅰ except 2 cases of type Ⅱ a in group six. In four torsion groups, the values for SER75 of the left side were 0. 084%, 0. 076%, 0.164% and 0.065%, while the right side were 0.255%, 0.410%, 0.586% and 0.302% (P ＜0.05). The values for SER120 in group three, five and six were 0.221% , 0.158% and 0.059% for the left side, and 0.405%,0.522% and 0.207% for the right side(P ＜0.05). The values for MSER in group three, five and six were 0.217% ,0.164% and 0.072% for the left side, and 0.405%, 0.586% and 0.302% for the right side(P ＜0.05). Conclusion DCE-MRI technique may be useful in the diagnosis of testicular torsion, which shows potential in the clinical application.
