[Summary] Obesity has been a great threat to people ’ s health.It is a kind of disease which lead to various metabolic diseases.Besides, there are significant difference in psychological status between obese people and normal population .Obese people have more psychological disorders , such as depression and anxiety .Some studies have suggested that psychological disorders can influence the result of bariatric surgery .In addition, bariatric surgery may relieve patients ’ psychological disorders .In this review, we focused on the mental aspect of bariatric surgery .

Objective To explore family functioning and related factors in anxiety disorder(AD)adoles cents.Methods 84 adolescent patients with AD and 124 controls without mental disorder matched by gender,age,and residential township were assessed with Family Adaptability and Cohesion Scale(FACES-Ⅱ),Family Assessment Device.Chinese version(FAD-CV)and demographic questionnaires.Results There were statistical differences between case and control groups in family economic conditions(P<0.05).There was lower family cohesion in AD group(64.82±9.63)than that in the control group(69.72±8.91);the scores of communication,emotional involvement and behavioral control were higher in AD group((2.34±0.45),(2.52±0.44),(2.46±0.32))than that in controls((2.12±0.34),(2.36±0.42),(2.24±0.24)),all P<0.05.Logistic regression analysis showed that better family economic condition(OR=0.784;95%CI:1.459-3.396)and higher cohesion of family(OR=0.969;95%CI:0.942～0.998)were protective factors for AD,while over-strict behavioral control (OR=2.181;95%CI:0.993～2.441)was a risk factor for AD.Conclusion There are different family functioning characters between AD and controls,and the intimacy relationship and suitable behavior control in family may improve the mental health of adolescents.

Objective To study the effects of rehabilitation training on angiogenesis and its ultrastructure and expression of CD32 in the peri-infarction region of rats with focal cerebral infarction. Methods Sixty-six Spra-gue-Dawley rats with experimental left middle cerebral artery occlusion (MCAO) were used as subjects in this study. All the rats were randomly divided into three groups: a rehabilitation training group (n=30), which was given bar rotating, balancing and rolling exercises everyday after 48 hours post MCAO; a control group (n = 30) and a sham-operated group (n=6), which were fed in cages with no special training exercises. Then brain tissues were fixed on the 3rd d, 7th d, 14th d after MCAO, for observing the morphological alterations of microvessels in peri-infarction re-gion using transmission electron microscope, immunohistochemistry and Western blotting were used to measure the ex-pression of CD31, which acted as the marker of the neogenetic microvessels. Results (1) It showed that the capil-lary endothelial cells were less edematous in the rehabilitation training group, and there were less pinocytosis bullae in basal membrane more integral nucleus of endothelial cells in rehabilitation training group when compared with those in the control group. (2) Expression of CD31 can be observed in peri-infarction region in both groups from the 3rd d on-wards, and peaked on the 7th d, and then gradually went down after the 14th d. Comparison between the 2 groups showed that the expression of CD31 in rehabilitation training group was higher than that in the control group at every time point, but statistical difference between the 2 groups in this regard could be revealed only on the 7th d (P< 0.05), Conclusion Rehabilitation training could promote ultrastruetural recovery of microvessels and induce an-giogenesis in peri-infaretion region, and it might be one of the mechanisms of neural functional recovery in rats after MCAO.

Objective To study the effects of rehabilitative training on motor function and expression of GAP-43 and SYN in rats with local cerebral infarction. Methods A total of 76 male adult Sprague-Dawley rats were randomly divided into a rehabilitative training group(n=32),a control group(n=32),and a sham-operated group(n=1 2).All the rats were subjected to left middle cerebral artery occlusion(MCAO)with the suture occlu sion.Motor training programs including balancing,grasping,rotating and walking exercises were administered to the rats of the rehabilitative training group at 48 hours post-operation,while those of other two groups were reared in their original living status without any special training.The animals were given behavioral tests with Bederson test,balancing wood test,net screen test to assess the functional outcome,and immunohistochemistry staining was employed to evaluate the exDression of GAP-43 and SYN in peri-infarction cortex at the 3rd,7th,21 st,35th days after MACO,respectively. Results The scores of behavioral tests in the rehabilitative training group was better than those in the control group(P＜0.05)at the 7th,21 st,35th day after MCAO,and the immunostaining showed that expression of GAP-43 was higher in the rehabilitative training group than that in the control group(P＜0.05)and the sham operated group(P＜0.01)at the 7th and 21 st days post-operation,respectively,and that the expression of SYN was higher in the rehabilitative training group than that in the control(P＜0.05)and the sham operated groups(P＜0.05)at the 21 st and the 35th days post-operation,respectively. Conclusion Rehabilitative training can improve func tional recovery in rats with local cerebral infarction,and the function enhancement may be partially attributed to the up-regulation of expression of GAP-43 and SYN in peri-infarction cortex.

Objective To identify the metabolite levels in prefrontal lobe and thalamus in patients of schizophrenia with proton magnetic resonance spectroscopy (1H-MRS). Methods Twenty-six schizophrenics with medicine-free for at least 7 d and 28 normal controls were assessed in this study. All subjects underwent examination of multi-voxel 1H-MRS on prefrontal lobe and thalamus within 24 h. The NAA, Cho and Cr were measured and the ratios of NAA/Cr, Cho/Cr and NAA/(Cho+Cr) were determined. Results Compared with the controls, the NAA/Cr ratio of schizophrenics was significantly lower in left prefrontal lobe and bilateral thalamus (all P＜0.05). No statistical difference of NAA/(Cho+Cr) ratio and the Cho/Cr ratio was found between two groups. Conclusion Abnormalities in neuronal function and/or integrity are present at left prefrontal lobe and bilateral thalamus simultaneously in schizophrenics.

ObjectiveTo investigate the prevalence of anxiety and depression among hepatitis B patients in Shanghai, China and related influencing factors. MethodsA cross-sectional survey was performed among 917 hepatitis B patients who were treated in Shanghai East Hospital, Tongji University, Shanghai Public Health Clinical Center, and Nanhua Hospital in Pudong New Area from June to December, 2016. The Hospital Anxiety and Depression Scale (HADS) and a self-designed social demography questionnaire were used for evaluation. The independent samples t-test and a one-way analysis of variance were used for comparison of continuous data between groups, and a multivariate linear regression analysis was used to analyze the correlation of anxiety and depression scores with demographic and socioeconomic factors. ResultsThe prevalence rates of anxiety and depression symptoms assessed by HADS were 87.6% and 90.7%, respectively. The severity of anxiety in hepatitis B patients was associated with age, family income, and educational level (F=3.518, 6.416, and 3322, all P＜0.05), and the severity of depression was associated with age, marital status, family income, occupation, and complications (F=2.904, t=2.242, F=22.840, F=9.235, F=11.870, t=2.246, all P＜0.05). High educational level, high income, and single status were risk factors for depression(all P＜005), and high income and the increase in age were significantly associated with anxiety(all P＜005). ConclusionAt present, the mental state of hepatitis B patients in Shanghai is not optimistic, with high prevalence rates of anxiety and depression. The results remind medical workers that they should pay attention to the mental health of hepatitis B patients.

Objective This study is to explore the association between self-differentiation and men-tal health among medical students. Methods Differentiation of self inventory-revised (DSI-R) and univer-sity personality inventory (UPI) were used to measure the self-differentiation and mental health of 526 med-ical students from Grade One to Grade Five at a comprehensive university in Shanghai. Result The mean score of DSI-R was (171.25±19.65). 32.2％ of participants had different levels of mental health prob-lems. Female students got higher score of DSI-R than male students (P=0.007). Statistically significant dif-ferences of medical students' self-differentiation were found among years of school attended (P=0.039). Sta-tistically significant differences of self-differentiation were also found between the first class and the third class of UPI (P<0.001) as well as the second class and the third class of UPI (P=0.004). Ordinal regression analysis indicated that self-differentiation was a risk factor for medical students' mental health (OR=1.036, P=0.000). Conclusion The average score of medical students' self-differentiation was higher than college students of other specialties. But their mental health condition was worse. Medical students with higher self-differentia-tion had worse mental health situation.
