Background: Patients with early onset depression (EOD) and late onset depression (LOD) have distinctive risk factors and clinical pictures. Using regional homogeneity (ReHo) approach, we were to test the hypothesis of the different abnormal neural activity between patients with EOD or LOD. Methods: Fifteen patients with EOD, 15 patients with LOD, 15 young healthy subjects (HS) and 15 old HS participated in the study. ReHo approach was employed to analyze the scans. Results: ANOVA analysis revealed widespread differences in ReHo values among the four groups throughout frontal, parietal, temporal, occipital cortex, cerebellum and limbic regions. Compared to LOD group, EOD group had higher ReHo in right precuneus (PCu) and bilateral superior frontal gyrus, and lower ReHo in left superior temporal gyrus. Compared to young HS, lower ReHo in left parahippocampal gyrus and higher ReHo in left fusiform gyrus and bilateral superior frontal gyrus were seen in EOD group; in contrast, in LOD group, lower ReHo in right PCu and higher ReHo in left superior temporal gyrus and left Crus I of the cerebellum were observed. Further ROC analysis suggested that the mean ReHo values in right PCu and bilateral superior frontal gyrus could serve as markers to identify patients with EOD from individuals with LOD. Limitation: The large age gap may limit the translational value of our findings. Conclusions: Patients with EOD and those with LOD have abnormal neural activities in different brain regions, although the two groups share the same symptoms. © 2012 Elsevier B.V.

Infant colic, excessive crying of unknown cause, is a major burden to families and effects about 10–30 % of infants. Despite decades of research, the exact cause and treatment of infant colic has remained elusive. The use of Lactobacillus reuteri (DSM 17938) in infant colic is somewhat controversial and hence, we designed this study to evaluate its efficacy in infantile colic. We recruited predominantly or exclusively breastfed infants, aged less than 4 months in a placebo controlled observational randomized study. Participants’ were assigned to receive L. reuteri at a dose 108 colony forming units (n = 21) and placebo (n = 21). Placebo was an identical formulation without live micro-organisms. Treatment was given to subjects for 21 days and they were followed for 4 weeks. Treatment success (primary outcome), daily reduction in crying time, parent satisfaction and reduction in maternal depression (secondary outcomes) were assessed at the end of study period. Treatment success was observed in all infants (100 %) of the probiotic group while it was seen in 15.7 % of the placebo group. Mean daily crying time was more significantly reduced to 32.1 ± 8.3 min/day (P < 0.01) from 200.9 ± 6.3 min/day in the probiotic group as compared to the placebo group (120.6 ± 20.0 min/day). Moreover, throughout the study period, parent’s satisfaction and improvement in maternal depression (Edinburgh postnatal depression scale) was also significantly higher in the probiotic group. In our study population, reduction in crying time was significant (P < 0.01) even during first week of initiation of therapy. We conclude that L. reuteri (DSM 17938) reduces daily crying time and maternal depression during infantile colic. We suggest L. reuteri may be a safe and efficacious option for reducing infant colic. © 2015, Springer International Publishing Switzerland.

Background Abnormalities of white matter integrity in frontal and limbic regions have been postulated to play a key role in the pathophysiology of geriatric depression. However, there is no diffusion tensor imaging (DTI) study in patients with first-episode, drug-naive, late-onset depression (LOD). The aim of this study was to investigate whole-brain fractional anisotropy (FA) difference between patients with LOD and healthy controls without a previously determined region of interest. Methods The sample included 15 patients with first-episode, drug-naive LOD and 15 age-, sex-, and education-matched healthy controls. The tract-based spatial statistics (TBSS) method was employed to analyze the DTI data. Results Lower FA in the white matter of bilateral parahippocampal gyrus was observed in patients with LOD relative to healthy controls by voxel-wise statistics with the TBSS method. Patients did not have higher FA values in any brain regions compared to healthy controls. There was no correlation between the abnormal FA value in bilateral parahippocampal gyrus and depression severity or related factors. Limitations The present study should be considered preliminary due to relatively small sample size. Conclusions Our findings suggest that loss of white matter integrity in parahippocampal gyrus may be associated with the pathophysiology of LOD, and thus highlight the limbic contribution to the pathophysiology of LOD. © 2014 Elsevier B.V.

Schizophrenia (SCZ) is a complex and heterogeneous mental disorder that affects about 1% of global population. In recent years, considerable progress has been made in genetic studies of SCZ. A number of common variants with small effects and rare variants with relatively larger effects have been identified. These variants include risk loci identified by genome-wide association studies, rare copy-number variants identified by comparative genomic analyses, and de novo mutations identified by high-throughput DNA sequencing. Collectively, they contribute to the heterogeneity of the disease. In this review, we update recent discoveries in the field of SCZ genetics, and outline the perspectives of future directions. © 2015, Shanghai Institutes for Biological Sciences, CAS and Springer-Verlag Berlin Heidelberg.

Objective: To evaluate the psychological status of patients with somatization disorders by using questionnaire survey and professional mental scale, aiming to provide effective coping strategies for psychological and physical recovery. Methods: Fifty patients diagnosed with somatization disorder and 50 corresponding family members were assigned into the study group. Fifty healthy subjects and 50 their family members were allocated into the control group. All participants received comprensive evaluation by using SCL-90, SSRS and CSQ. Results: In the study group, the average scores of a majority of items in the SAS and SDS were significantly higher than those in the control group (all P<0.05). The mean scores of overall social and subjective support in patients with somatization disorder were considerably lower than those in their counterparts (all P<0.05). In the study group, the average score of negative factor was significantly higher whereas that of the positive factor was apparently lower compared with the values obtained in the control group (all P<0.05). Conclusion: Patients diagnosed with somatization disorder and their family members present with evident psychological symptoms, lack of social support and effective strategy against the symptoms of somatization disorder. © 2016, E-Century Publishing Corporation.

The present study investigated the antidepressant potential of curcumin in olfactory bulbectomy and forced swimming test models of depression in male albino rats under chronic treatment. The experimental animals were divided into four groups, and curcumin was administered for 45 days. Our results showed that the curcumin significantly reduced olfactory bulbectomy-induced behavioral abnormalities including deficits in step-down passive avoidance, increased activity in the open area and immobility time. Chronic administration of curcumin significantly reversed levels of 3, 4-dihydroxyphenylacetic acid, noradrenaline, serotonin and 5-hydroxyindoleacetic acid in the hippocampus region of male albino rats. Also, curcumin normalizes the levels of dopamine, noradrenaline, and 5-hydroxyindoleacetic acid in the frontal cortex of rats. Taking all these results together, it may suggest that curcumin is potent compound acting against the depression in the male albino rats. © 2016, Elsevier B.V. All rights reserved.

Objective Effects of conventional and atypical antipsychotics on bone mineral density (BMD) and serum prolactin levels (PRL) were examined in patients with schizophrenia. Methods One hundred and sixty-three first-episode inpatients with schizophrenia were recruited, to whom one of three conventional antipsychotics (perphenazine, sulpiride, and chlorpromazine) or one of three atypical antipsychotics (clozapine, quetiapine, and aripiprazole) was prescribed for 12 months as appropriate. BMD and PRL were tested before and after treatment. Same measures were conducted in 90 matched healthy controls. Results Baseline BMD of postero-anterior L1-L4 range from 1.04 ± 0.17 to 1.42 ± 1.23, and there was no significant difference between the patients group and healthy control group. However, post-treatment BMD values in patients (ranging from 1.02 ± 0.15 to 1.23 ± 0.10) were significantly lower than that in healthy controls (ranging from 1.15 ± 0.12 to 1.42 ± 1.36). The BMD values after conventional antipsychotics were significantly lower than that after atypical antipsychotics. The PRL level after conventional antipsychotics (53.05 ± 30.25 ng/ml) was significantly higher than that after atypical antipsychotics (32.81 ± 17.42 ng/ml). Conditioned relevance analysis revealed significant negative correlations between the PRL level and the BMD values after conventional antipsychotics. Conclusion The increase of PRL might be an important risk factor leading to a high prevalence of osteoporosis in patients with schizophrenia on long-term conventional antipsychotic medication.

Disturbance of the serotonergic system contributes to the etiology of bipolar disorder (BD). Tryptophan hydroxylase-2 (TPH2) is an important rate-limiting enzyme in the synthetic pathway for brain serotonin and has been suggested to play a role in BD.We performed a systematic review and meta-analysis of all studies to date investigating the association studies between TPH2 and BD published before Aug 2014. All studies were abstracted from PubMed, Embase, HuGNet, and China National Knowledge Infrastructure (CNKI). Manuscripts and the supplementary documents of published genome-wide association studies in the field were also included. Effect sizes of independent loci that have been studied in more than three articles were synthesized using fixed and random effects models.Eight eligible studies addressed association between 63 TPH2 gene single nucleotide polymorphisms (SNPs) with BD, after linkage disequilibrium analysis, 12 independent SNPs were identified. Finally, three SNPs (rs4760820, rs11178998, and rs7954758) were found associated with BD using fixed effects models, and rs4760820 and rs11178998 were still associated with BD even with the more conservative random effects models.rs4760820 and rs11178998 were identified to have strong genetic association with BD in present study though confirmation will require larger sample sizes and in additional populations.

Neovibsanin type natural products were found to display neurite outgrowth activity in PC12 cells. This suggests that such type of compounds could be promising candidates for the development of novel therapeutic agents to treat neurological diseases. In the present study rats after chronic mild stress (CMS) were treated with tricyclic neovibsanin scaffold (TCNS) to study its effect on depression. The results revealed that 15mg/kg doses of TCNS reduced the duration of immobility in CMS model of depression. It led to a significant increase in neurite outgrowths which increased the synaptic and structural plasticity of neurons. Treatment with TCNS decreased the levels of MAO-A and caspase-3 expression both of which were found to be higher in CMS. TCNS also led to an increase in expression of heat shock protein 70 (Hsp70) in the hippocampus. These findings suggest that TCNS possesses antidepressant activity in CMS model of depression. Therefore the relief in depression by TCNS may be due to suppression of MAO-A expression and the apoptosis cascade by increased expression of Hsp70.
