Glucose uptake and metabolism are impaired in Alzheimer's disease (AD) brain, which appear to be a cause, rather than a consequence of neurodegeneration. Recently, the gene of the 14th isoform of subfamily A of solute carrier family 2 (SLC2A14), encoding glucose transporter 14 (GLUT14), was identified for the association in vivo with AD pathology of Tau, and rs10845990 within SLC2A14 showed association with AD in Caucasians. In order to evaluate the involvement of the SLC2A14 polymorphism in the risk of developing late-onset Alzheimer's disease (LOAD) in Chinese, we performed an independent case-control association study in a Han Chinese population (597 LOAD cases and 605 healthy controls). There were significant differences in genotype and allele frequencies between LOAD cases and controls (genotype P=0.015, allele P= 0.039). The G-carrying genotype (GT+GG) individuals showed a 1.41-fold increased risk compared with the TT genotype carriers (odds ratio (OR)01.41, 95% confidence interval (CI)=1.11-1.79, P00.005, Power083.6%). After stratification by ApoE ε4-carrying status, rs10845990 polymorphism was only significantly associated with LOAD in non-ApoE ε4 allele carriers (P<0.001). Multivariate logistic regression analysis also conferred this positive association between the SNP rs10845990 and LOAD in the dominant and additive model after adjustment for age, gender, and the ApoE ε4 carrier status. These results suggested that SLC2A14 polymorphism has a possible role in changing the genetic susceptibility to LOAD in a Han Chinese population. © Springer Science+Business Media LLC 2012.

Objective The aim is to comparatively study Shugan Jieyu capsule and sertraline for non-inferiority in the treatment of patients with acute myocardial infarction and depression (observing the curative effects and safety) by the randomized controlled experiment. Methods A total of 149 patients with acute myocardial infarction and depression were randomly divided into two groups, the Shugan Jieyu group (76 cases) and the sertraline group (73 cases), and received treatments for 24 weeks. Depression states were assessed by the rote diagnostic checklist, and effects were evaluated by the Hamilton depression scale. Drug safety for heart was assessed by left ventricular ejection fraction (reduced by 5%), blood pressure, heart rate, P-wave and R wave interval, Q-R-S complex wave, and corrected Q-T interval after 12 weeks of treatment. Results There were no significant differences in the effective rates of Shugan Jieyu and sertraline groups. Significantly lower adverse event rate was observed in the Shugan Jieyu group. Two groups had a similar cardiac safety. Conclusion Shugan Jieyu capsule has a reliable effect and high safety in patients with acute myocardial infarction and depression. © The Author(s) 2017.

Background Although outcomes among people with schizophrenia differ by social context, this has rarely been examined across rural v. urban settings. For individuals with schizophrenia, employment is widely recognised as a critical ingredient of social integration. Aims To compare employment for people with schizophrenia in rural v. urban settings in China. Method In a large community-based study in four provinces representing 12% of China's population, we identified 393 people with schizophrenia (112 never treated). We used adjusted Poisson regression models to compare employment for those living in rural (n = 297) v. urban (n = 96) settings. Results Although rural and urban residents had similar impairments due to symptoms, rural residents were three times more likely to be employed (adjusted relative risk 3.27, 95% CI 2.11-5.07, P50.001). Conclusions People with schizophrenia have greater opportunities to use their capacities for productive work in rural than urban settings in China. Contextual mechanisms that may explain this result offer a useful focus for future research.

Antipsychotic drugs have been inconsistently associated with death risk of Alzheimer's disease (AD) patients. Herein we review and quantitatively summarize the evidence from epidemiological studies. Pertinent studies were identified by searching PubMed and Cochrane Library Register of Controlled Trials through 20 December 2015. The DerSimonian and Laird random effect model was adopted as the pooling method. Twelve studies from nine articles with 11,463 participants were included. The pooled RR of observational studies was 1.36 (95 CI, 0.83-2.24; I2 = 94.9) for antipsychotic drugs users versus individuals who were not exposed to antipsychotic drugs. When the three studies that were key contributors to the high heterogeneity were excluded, the pooled RR was 2.08 (95 CI 1.39 to 3.13). The result of one double-blind randomized clinical trial indicated that antipsychotic drugs nearly doubled the risk of death in AD patients. In conclusion, there is no evidence of absence of association between antipsychotic drugs' use with death risk of AD patients. Careful assessments of potential benefits and risks should be made before prescribing antipsychotics for treatment of psychosis symptoms and behavioral problems of AD patients.

Variants in the clusterin gene have been associated with Alzheimer's disease (AD) through replicated genome-wide studies, but the underlying mechanisms remain unknown. In this study the association of the AD clusterin common risk polymorphism rs9331888 with blood clusterin levels was tested in 104 AD subjects and 104 healthy controls. Blood clusterin levels were significantly elevated in AD patients (p < 0.05). The rs9331888 AD-risk variant was associated with low clusterin mRNA and protein levels in an allele-dose dependent manner in both groups (p < 0.001). This study indicates that the rs9331888 AD-risk variant is associated with low blood clusterin levels. © 2012-IOS Press and the authors. All rights reserved.

Toll-like receptor 4 (TLR4) represents a reasonable functional and positional candidate gene for Alzheimer's disease (AD) as it is located within the previous identified linkage region of AD on chromosome 9q, and functionally is involved in the microglia-mediated inflammatory response, amyloid-β (Aβ) plaque formation and Aβ clearance. To test whether variants in the TLR4 gene are associated with late-onset AD (LOAD), we organized a multicenter study of 785 subjects (399 cases and 386 matched controls) in a Han Chinese population. Ten single nucleotide polymorphisms (SNPs) that span the TLR4 gene, from approximately 5 kb of the predicted 5'-untranslated region (UTR) to approximately 6 kb of the predicted 3'- UTR, were selected and their associations with LOAD risk factors were assessed. With respect to allelic diversity, the minor alleles of seven SNPs (rs10759930, rs1927914, rs1927911, rs12377632, rs2149356, rs7037117, and rs7045953) in TLR4 showed consistent protective effects against the risk of developing LOAD. With regard to genotypic diversity, individuals carrying at least one minor allele of each SNP above had a consistently lower risk of LOAD than those with no copies of the minor alleles (ORs ranging from 0.445 to 0.637). rs7045953, located in the 3'-UTR of TLR4, was most strongly associated with LOAD, and when incorporated into a haplotype with rs10759930, the strongest association was detected (P = 1.7×10 -6, Pc =1.0×10 -4). Our data suggests that the TLR4 gene contributes to the susceptibility for LOAD in Han Chinese. © 2012 Bentham Science Publishers.

Objective: Five genomewide association studies (GWAS) in white populations have recently identified and confirmed 9 novel Alzheimer's disease (AD) susceptibility loci (CLU, CR1, PICALM, BIN1, ABCA7, MS4A gene cluster, CD2AP, CD33, and EPHA1). These studies have been conducted almost exclusively in white populations and it is unclear whether these observations generalize to populations with different ethnicities. Methods: We recruited 1224 unrelated northern Han Chinese subjects comprising 612 patients with a clinical diagnosis of late-onset AD (LOAD) according to the criteria of the National Institute of Neurological and Communicative Diseases and Stroke/Alzheimer's Disease and Related Disorders Association and 612 healthy age- and sex-matched control subjects. Because of our previous study investigating CLU, CR1, and PICALM in the Han population, we limited the current analysis to BIN1, ABCA7, MS4A gene cluster, CD2AP, CD33, and EPHA1. Results: In a multivariate analysis, associations of MS4A6A (rs610932; odds ratio = 0.632, Bonferroni corrected P =.019) and CD33 (rs3865444; odds ratio = 1.492, Bonferroni corrected P =.017) with LOAD were replicated successfully. When these data were stratified by apolipoprotein E (APOE) ε4 status, both rs610932 and rs610932 were evident only among subjects without the APOE ε4 allele. For BIN1, assuming a dominant model of inheritance, a positive association for rs7561528 in APOE ε4 carriers was observed. This association, however, did not remain significant after Bonferroni correction. As for ABCA7, CD2AP, and EPHA1 single nucleotide polymorphisms from recent GWAS, despite the similar directional effects, no significant differences in genotype and estimated allele frequency distribution between patients and control subjects were observed. Conclusions: This study provides the first independent evidence that MS4A and CD33 loci are associated with the risk of LOAD in northern Han Chinese population. Genotypes at the two loci confer risk predominantly in APOE ε4-negative subjects. © 2013 The Alzheimer¢s Association. All rights reserved.

Background Oligodendrocyte transcription factor 2 (OLIG2) is primarily concentrated in the brain and spinal cord ventricular zone, where this protein stimulates oligodendrocytes and specific neurons, determines motor neuron and oligodendrocyte differentiation, and sustains replication in early development. Recent studies have demonstrated that OLIG2 gene is associated with mental disorders, such as schizophrenia, mood disorder, and obsessive-compulsive disorder (OCD). Methods The aim of the present study was to explore whether OLIG2 gene is associated with OCD in a Chinese Han population through the assessment and analysis of three single nucleotide polymorphisms (SNPs), namely, rs762178, rs1059004, and rs9653711, selected from OLIG2 gene sequences from 400 OCD samples and 459 healthy controls in a case-controlled association study. Results We demonstrated three principal results. First, SNP rs762178 was associated with OCD, female OCD, and early-onset OCD; rs1059004 was associated with OCD and early-onset OCD; and rs9653711 was also associated with OCD and early-onset OCD. Second, the pairs of loci rs762178 and rs1059004, rs1059004 and rs9653711, and rs762178 and rs9653711 exhibited linkage disequilibrium. Third, the three-locus A-C-G haplotype was associated with early-onset OCD. Conclusions The present study is the first to verify the associations of SNPs rs762178, rs1059004, and rs9653711 of the OLIG2 gene with OCD in a Chinese Han population. Thus, OLIG2 might serve as a potential target for OCD treatment in future studies. Further studies should verify the current findings. © 2015 Wiley Periodicals, Inc.

Toll-like receptor 2 (TLR2) represents a reasonable functional and positional candidate gene for Alzheimer's disease (AD) as it is located under the linkage region of AD on chromosome 4q, and is functionally involved in the microglia-mediated inflammatory response and amyloid β (Aβ) clearance. In the current study, 7 single nucleotide polymorphisms (SNPs) that span the TLR2 were selected and their associations with late-onset AD (LOAD) risk were assessed in a case-control sample comprising 785 individuals in a Han Chinese population. No significant differences in the frequency of TLR2 alleles, genotypes, and haplotypes in the AD cases were detected compared with the controls. TLR2 gene might not play a major role in the genetic predisposition to late-onset Alzheimer's disease in this population. © 2011 Elsevier Inc.

Background: Anxiety is common in stroke survivors and may adversely affect recovery. Polymorphisms of tryptophan hydroxylase2 (THP2) gene have been shown to be associated with anxiety disorders and other affective disorders. This study was aimed to investigate the association of two polymorphisms of THP2 gene, rs4570625 and rs4565946, with poststroke anxiety disorders in a Han Chinese population. Methods: This case control study included 112poststroke anxiety patients and 246 non-anxious controls. All participants completed Hamilton Anxiety Rating Scale and DNA was extracted from blood and genotyped for the two polymorphisms of THP2 gene. Results: Results revealed that the G allele of rs4570625 was associated with the increased risk of poststroke anxiety. In the female subgroup, both the GG genotype and G allele were observed to be significantly higher in case than in control. No significant difference in genotype and allele frequencies of the rs4565946 was found between case and control. Haplotype analysis identified that patients with the G-C haplotype had significantly increased the risk of poststroke anxiety. Limitations: More than 20 TPH2 polymorphisms have been detected, some of which are tightly-linked and may function together, only two SNPs of TPH2 were investigated in this study. Conclusions: The findings suggest that these polymorphisms in TPH2 gene are involved in development of poststroke anxiety in the Han Chinese population. © 2012 Elsevier B.V. All rights reserved.
