RESUMO

<p><b>OBJECTIVE</b>To investigate the relationship between monoamine oxidase A (MAOA) gene polymorphisms and schizophrenia in a Chinese Han population.</p><p><b>METHODS</b>Two hundred and twelve schizophrenic patients and 168 healthy controls were recruited according to CCMD-3. The polymorphisms of MAOA gene were determined with the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. The case-control association analysis was adopted to analyze the frequencies of genotype and allele in schizophrenic patients and controls.</p><p><b>RESULTS</b>(1) The genotypes of MAOA gene were consistent with Hardy-Weinberg equilibrium in patient group and control group (chi2 = 0.618, df= 2, P> 0.05; chi2 = 3.173, df= 2, P> 0.05). (2) The distributions of genotypes or alleles of MAOA genes had no significant difference between patient group and control group (P> 0.05). (3)Divided by sex, the frequency of CT genotype in male patients was higher than that in male controls (chi2 = 7.654, P= 0.022). (4) There were no significant differences of genotypic and allelic distribution in MAOA genes between schizophrenic patients with positive family history and schizophrenic patients with negative family history and among different clinical subtypes in schizophrenic patients (P> 0.05).</p><p><b>CONCLUSION</b>No association between MAOA gene and schizophrenia is found in Chinese Han population, but CT genotype is likely to be a susceptible factor of male schizophrenia.</p>

RESUMO

Objective To study the change of vascular endothelial growth factor(VEGF) in myocardial tissue and serum of myocardial ischemia in rats.Methods Twenty SD rats were randomly divided into normal control group and test group. Test group was ligated coronary artery,and the control group was pulled on line but not ligated,then observed the change of VEGF.The histological and immunohistochemical method were used for observing the change of VEGF serum in myocardial ischemia in rats' heart.VEGF levels were measured by image analysis.Results Compared with control group,the expression of VEGF in the myocardial ischemia group was increased obviously(P
