Adopting the theory of group fairness strategy put forward by Lawrence Kohlberg,an integrity education aimed at medical students is carried out on the basis of class,with teachers,family members and social individuals as cooperators.The integrity education could be promoted by setting up an independent nature,and educational idea of selective moral personality.It puts the core content of impartial democratic participation into effect,takes the morality sense of responsibility education as basis,constructs a democratic participation atmosphere,and emphasizes the significance of daily life during the integrity education in order to promote the cultivation of integrity quality of medical students.

The incidence of inflammatory bowel disease (IBD) is increasing year by year, yet lacking specific treatment, which seriously affects patients' health and quality of life. The pathogenesis of IBD has not been fully clarified, the psycho-neuro-endocrine-immune regulation through gut-brain axis may play an important role in the pathogenesis of IBD. Studies have shown that IBD patient has an increased risk of depression. More than 20% of IBD patients have depression, the incidence is about 2-4 times that of general population. Antidepressant therapy has good efficacy in some IBD patients. The possible mechanism includes affecting the gut-brain axis, inhibiting inflammation, improving mood, etc. However, there are few relevant studies, and the value of antidepressant therapy in the treatment of IBD needs to be further confirmed by large-sample randomized controlled studies. This article reviewed the application of antidepressant therapy in IBD.

Objective To study placental microcirculation and microstructure of pregnant women with pregnancy-induced hyper-tension by using MRI intravoxel incoherent motion(IVIM)at plateau area.Methods A retrospective analysis was performed on 22 healthy pregnant women at third trimester with single birth and 20 pregnant women with pregnancy-induced hypertension.All subjects underwent ultrasound,routine MRI and IVIM examination.The D,D*,f values of the whole placental and various parts of the placental,estimated fetal weight(EFW)and postnatal weight were measured and recorded.The differences of two groups data were analyzed by independent sample t test or one-way analysis of variance,and then multiple comparisons of placental quantitative parameters between the two groups were analyzed by Bonferroni method.Results The fetal side and whole placental f values in healthy pregnant women at third trimester were higher than pregnancy-induced hypertension(P＜0.05),the maternal side and whole placental D values in healthy pregnant women at third trimester were higher than pregnancy-induced hypertension(P＜0.05),the EFW and fetal birth weight in healthy pregnant women at third trimester were higher than pregnancy-induced hypertension(P＜0.05).Conclusion IVIM can effectively evaluate placental blood flow microcirculation and microstructure with pregnancy-induced hypertension at plateau area,and provide a new proof for clinical evaluation of placental structure and function changes.
