RESUMO
Introduction: The branched-chain amino acids (BCAAs) are essential to mammalian growth and development but aberrantly elevated in obesity and diabetes. Each BCAA has an independent and specific physio-biochemical effect on the host. However, the exact molecular mechanism of the detrimental effect of valine on metabolic health remains largely unknown. Methods and results: This study showed that for lean mice treated with valine, the hepatic lipid metabolism and adipogenesis were enhanced, and the villus height and crypt depth of the ileum were significantly increased. Transcriptome profiling on white and brown adipose tissues revealed that valine disturbed multiple signaling pathways (e.g., inflammation and fatty acid metabolism). Integrative cecal metagenome and metabolome analyses found that abundances of Bacteroidetes decreased, but Proteobacteria and Helicobacter increased, respectively; and 87 differential metabolites were enriched in several molecular pathways (e.g., inflammation and lipid and bile acid metabolism). Furthermore, abundances of two metabolites (stercobilin and 3-IAA), proteins (AMPK/pAMPK and SCD1), and inflammation and adipogenesis-related genes were validated. Discussion: Valine treatment affects the intestinal microbiota and metabolite compositions, induces gut inflammation, and aggravates hepatic lipid deposition and adipogenesis. Our findings provide novel insights into and resources for further exploring the molecular mechanism and biological function of valine on lipid metabolism.
RESUMO
Objective·To explore the effectiveness and feasibility of social cognitive and interactive training (SCIT) in rehabilitation of schizophrenic patients, and propose to establish a new mode of community rehabilitation. Methods·A total of 60 patients with schizophrenia managed in the community in Shanghai Hongkou District were divided into control group and intervention group with 30 cases in each group. The control group was treated with conventional community management. The intervention group accepted SCIT courses at the base of conventional community management. Before and after the intervention, all patients completed the related scales for schizophrenia. Scale scores were analyzed with analysis of variance by SPSS 22.0 to explore the rehabilitation effect of training. Results·In intervention group, the time used in the face emotion identification task (FEIT) had no significant difference with the control group, but the correct rate for FEIT increased significantly. In intervention group, ambiguous intentions hostility questionnaire-ambiguous items (AIHQ-A) scores were significantly lower. The total and sub scale scores of positive and negative syndrome scale (PANSS) and scale for assessment of negative symptoms (SANS), Calgary depression scale for schizophrenia (CDSS) scores were significantly decreased in intervention group. Otherwise, Toronto alexithymia scale (TAS) scores also decreased. Personal and social performance scale (PSP) scores in the SCIT group were increased after training. Finally, according to the training participation and the feedback of the patients, the training had a higher degree of acceptance and positive affirmation. Conclusion·SCIT can improve the social cognition and social function of schizophrenic patients in the community, also improve the mental symptoms, especially the negative symptoms and depressive symptoms, and has high feasibility and acceptability, so it can be promoted in community-based rehabilitation.
RESUMO
<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of Chaihu Xiaoyao Mixture (CXM) for the treatment of major depressive disorder (MDD).</p><p><b>METHODS</b>One hundred and ninety patients with MDD were randomly assigned to two groups, the test group and the control group. They were treated by paroxetine combined with CXM or placebo for 8 weeks. The therapeutic efficacy was evaluated at the end of the 2nd, 4th and 8th week by scoring according Hamilton Rating Scale for Depression (HAMD-17) and Clinical Global Impression (CGI) scale, and the adverse reaction was scaled by Treatment Emergent Symptoms Scale (TESS).</p><p><b>RESULTS</b>Follow-up study was completed in 89/92 patients in the test group, and 93/98 patients in the control group, with 3 and 5 cases dropping, respectively. The effective rate in the two groups was 84.8% and 71.4%, and the cure rate was 69.6% and 55.1%, respectively, which were significantly higher in the test group than in the control group (chi2=4.92, P<0.05; chi2=4.22, P<0.05). As compared with the baseline, significant differences in HAMD-17 total score and scores of its various factors as well as the CGI score were shown in both groups after 2, 4 and 8's week treatment (P<0.01). Comparison between groups showed that significant differences presented in HAMD-17 total score and CGI score at the end of the 8th week (P<0.01), while comparison of adverse reactions between groups showed insignificantly statistical difference (P>0.05).</p><p><b>CONCLUSION</b>Combined treatment of CXM and paroxetine is more effective than that with paroxetine alone in treating MDD, and it could enhance the clinical efficacy with higher safety.</p>

<p><b>BACKGROUND</b>Depressive disorder is a well-known chronic, recurrent and disabling mental disease with high direct and indirect costs to society in both western and eastern cultures. Approximately 40% of depressed patients show only partial or no response to initial or even multiple antidepressant medications and are usually called treatment-resistant depression (TRD) patients. The present work was to measure the features of sensory gating (SG) P50 in TRD patients with the intent of understanding the characteristics of this disease.</p><p><b>METHODS</b>In 50 TRD patients, 39 non-treatment-resistant depression (NTRD) patients and 51 healthy controls (HC), auditory evoked potential P50 was measured using the conditioning/testing paradigm presented with auditory double clicks stimuli, and 36 TRD patients had repeated measurements after an 8-week venlafaxine treatment course.</p><p><b>RESULTS</b>All the depressive disorder patients, including the TRD and NTRD groups, showed an increased testing stimulus wave (S2-P50) amplitude compared to controls (P < 0.01 and P < 0.05), but there was no significant difference between the TRD and NTRD groups (P > 0.05). There were significant differences in the ratio of testing stimulus (S2) and conditioning stimulus (S1) (S2/S1) and in the value of 100 x (1 - S2/S1) among the three groups. Compared to the baseline, TRD patients had no significant changes of features and different expression of P50 after acute treatment (P > 0.05). Meanwhile, a statistically significant positive correlation of S2/S1 with the scores of the 17-item Hamilton Rating Scale for Depression (HAMD-17) (P < 0.01), and a significantly negative correlation of S1 - S2, 100 x (1 - S2/S1) with the scores of HAMD-17 (P < 0.01) were observed in the TRD patients' baseline measurement, but there was no correlation after venlafaxine treatment (P > 0.05).</p><p><b>CONCLUSIONS</b>Both the TRD and NTRD patients had obvious SG deficits, with a more severe deficit in TRD patients. Although, with a correlated relationship to the severity of depressive symptoms, SG P50 deficit might be suggested as a trait marker for TRD, and a combination of S2/S1 ratio, S1 - S2 and 100 x (1 - S2/S1), was recommended for electrophysiological measurement in TRD patients.</p>
