The investigation of students' attitude to psychiatry and the teaching quality evaluation in clinical practice teaching / 中华医学教育探索杂志

Objective To understand students' attitude changes before and after they started their internships in the department of psychiatry and evaluate their teachers' teaching methods. Methods Using a self-made questionnaire of Psychiatric Internship Attitude that has passed the reliability and validity test, from 2015 to 2016, a total of 208 undergraduate students in the clinical medicine mental health direction of Chongqing Medical University were selected through cluster random sampling to investigate their attitude changes towards psychiatry before and after they started their internships. At the end of their internships, another self-made Psychiatric Teach Evaluation Forming Questionnaire of the reliability and validity test was used to preliminarily evaluate the students' assessment of the teaching situation of their teachers during the internship. Results Before the internships, through the survey we found that 44.2% of the students felt nervous, 37.0% fearful, 57.2% compassionate, and the percentage of students who were willing to work in the department of psychiatry is only 41.4%. Through investigation, teachers carried out the teaching work with targeted goals, at the end of the internship the tension and fear decreased to 0.0%, the proportion of empathy rose to 78.4%, and the differences are statistically significant (P<0.05). Conclusion The students' attitude survey at the beginning of their internship can help teachers improve their teaching attitudes, con-cepts and methods, and make students' negative attitudes towards mental patients and psychiatry significantly reduce.

The characteristic of fractional amplitude of low frequency fluctuation in depression patients with suicidal ideation:a resting-state functional magnetic resonance imaging study / 中国神经精神疾病杂志

Objective To explore the characteristic of fractional amplitude of low frequency fluctuation (fALFF) and the relationship with the severity of depression, suicidal ideation and suicide risk in depression patients with suicidal ideation with resting-state functional magnetic resonance imaging (rs-fMRI). Methods Resting state functional magnetic resonance imaging maps were conducted using fractional amplitude of low frequency fluctuation (fALFF) in 52 depression patients (30 with suicidal ideation and 22 without) and 21 healthy controls (HCs). The severity of depression was evaluat-ed by using Hamilton Depression scale(HAMD). The suicidal ideation, the suicide risk in depression patients with sui-cidal ideation were both assessed by the Beck Scale for Suicide Ideation. The correlation between the fALFF value and the score of HAMD and the Beck Scale for Suicide Ideation was analyzed. Results MRI revealed significant differences in fALFF in the left superior/middle occipital gyrus and the right middle/inferior occipital gyrus (P<0.05, AlphaSim cor-rected)between depression patients with suicidal ideation and the HCs. Compared to the HCs, depression patients with-out suicidal ideation showed a higher fALFF in the left middle occipital gyrus (P<0.05, AlphaSim corrected). MRI re-vealed significant differences in fALFF in the left middle occipital gyrus (P<0.01, AlphaSim corrected)and the right mid-dle occipital gyrus (P<0.01, AlphaSim corrected) between depression patients with suicidal ideation and without. The fALFF of left middle occipital gyrus (r=0.366, P=0.046) and right middle occipital gyrus (r=0.513, P=0.004) were posi-tively correlated with the scores of HAMD, respectively whereas were not correlated with suicidal ideation and suicide risk. Conclusions Depression patients with suicidal ideation have an abnormal spontaneous activity in their left and right middle occipital gyrus. The increased activity in these brain areas are probably associated with the severity of de-pression whereas are not associated with suicidal ideation or suicide risk.

Research on amplitude of low-frequency fluctuation in patients with major depression based on resting-state functional magnetic resonance imaging / 生物医学工程学杂志

We investigated the baseline brain activity level in patients with major depressive disorder (MDD) by am plitude of low-frequency fluctuation (ALFF) based on resting-state functional MRI (fMRI). We examined 13 patients in the MDD group and 14 healthy volunteers in the control group by resting-state fMRI on GE Signa 3.0T. We calculated and compared the ALFF values of the two groups. In the MDD group, ALFF values in the right medial prefrontal were higher than those in control group, with statistically significant differences (P < 0.001). ALFF values in the left parietal in the MDD group were lower than those in control group with statistically significant differences (P < 0.001). This resting-state fMRI study suggested that the alteration brain activity in the right medial prefrontal and left parietal ALFF contributed to the understanding of the pathophysiological mechanism of MDD patients.

Analysis of driving adaptability based on psycho-social factors / 中华创伤杂志

Objective To discuss the impact of relevant psycho-social factors on the driving adaptability. Methods A total of 870 vehicle drivers were screened out by stratified cluster sampling,and 620 drivers were finally selected for this study after eliminating those who had 1 -2 accidents. The 620 drivers were divided into accident group and non-accident group. Demographic questionnaire, life event scale, SCL-90 Scale and Eysenck Personality Questionnaire were applied to investigate their general condition, life event, mental health and personality. All data were analyzed by t test and stepwise Fisher discriminatory, and then the discriminatory equations of driving eligibility were established. Results The scores of factors including positive life events, negative life events, family events, work events and social events in accident group were 9.62 ± 11.36, 34.53 ± 30.01, 24.05 ± 23.09, 16.78 ± 17. 12 and 2.82 ± 5.07, respectively, which were higher than 4.67 ± 6.25, 6.38 ± 10. 15, 6.48 ± 9.43, 3.96 ±6.55 and 2.02 ± 5.43 respectively in the non-accident group ( P ＜ 0. 01 ). The total SCL-90 score and the scores of all factors in the accident group were higher than those in the non-accident group ( P ＜0. 01 ). The Eysenck Personality Questionnaire scores of the accident group were significantly higher than the non-accident group in N dimension ( 56. 32 ± 8.77 vs. 45.23 ± 8.06 ) and P dimension (52.22 ±10.43 vs. 48.31 ± 9.35 ) ( P ＜ 0. 01 ). Fisher discriminatory equations: Faccident group = 0. 258 × X6 + 0.119 ×X9 +0.637 ×X17 +0.043 × X5-7.476; Fnon-accident group =0. 137 × X6-1. 000 ×X9 + 1.423 ×X17 +0.003× X5-2.601. Total discrimination accuracy of verification was 88.3%, and the total accuracy of prospective discrimination was 88.0%. Conclusions There is clear correlation of driving adaptability with coercion, anxiety, emotion and negative factors. The discriminatory equations are useful for selecting drivers because of high accuracy, and may play an important role in reducing the occurrence of traffic accidents.
