RESUMEN
OBJECTIVE To assess the association of single nucleotide polymorphisms (SNPs) of the T-cadherin (CDH13) gene with metabolic syndrome (MS) among ethnic Han Chinese.METHODS Genotypes of 6 SNPs(rs11646213, rs12596316, rs3865188, rs12444338, rs12051272, and rs7195409) of the CDH13 gene among 453 patients with MS and 526 controls were determined with a TaqMan method, and their association with MS was assessed. RESULTS For 5 SNPs (rs11646213, rs3865188, rs12444338, rs12051272, and rs7195409), no difference was found in allelic and genotypic frequencies of the CDH13 gene between the two groups. Comparing with rs12596316 (AA+GG) genotype, rs12596316 AG genotype has significantly increased the risk of MS(P = 0.01,OR = 1.38,95%CI: 1.07-1.78), though no association was found between particular alleles of the rs12596316 with MS.There was no difference in the frequencies of rs11646213-rs12596316-rs3865188-rs12444338-rs12051272 haplotype between the two groups(P > 0.05). CONCLUSION No association was found between the five SNPs (rs11646213, rs3865188, rs12444338, rs12051272 and rs7195409) of the CDH13 gene with the MS, while the rs12596316AG genotype of the CDH13 gene is associated with the susceptibility to MS among ethnic Han Chinese.
RESUMEN
Objective To understand the characteristics and rules of behavior and preliminary study on the change of psychological state and behavior of infant rhesus monkeys after weaning by artificial feed .Methods 290 infant rhesus monkeys were born in 2012, individual behavior of infant rhesus monkeys were observed and recorded by the methods of ad libitum sampling and chronography .Results The behavior of huddling , sucking finger and sucking body of companion were observed in the first month , the behavior of huddling and sucking finger were significantly increased in the second and third month(P <0.05), sucking body of companion in second month were significantly higher than the first month (P <0.05);the new behavior pacing , sucking genitalia and mounting were observed in the second month , pacing and sucking were significantly increased in the third month ( P <0.05 ) , mounting did not have obvious change; in the third month , sucking toe behavior ware recorded and did not change with time; The proportion of huddling behavior occurred between female and female was significantly higher than opposite sex or male in the same cage .The male infant monkeys were more likely to occurred pacing behavior than female .Sucking body of companion and sucking finger behavior of male were significantly lower than the female infant monkeys ( P <0.05 ) .There was no significant difference of sucking toe behavior .Conclusions 7 behaviors were recorded during the whole stage of observation , huddling behavior , pacing behavior , sucking toe behavior , sucking finger behavior , sucking genitalia behavior , sucking body of companion behavior and mounting behavior respectively , and 7 behaviors were increased by degrees with time .Huddling behavior to reflect fear psychology;sucking behavior to represent physiological demand and defensive psychology ;pacing was insignificant behavior in the initial stage , then to reflect psychological anxiety of rhesus monkeys .Provided a way and model on assessment of psychology, praxiology, to study and research the change of psychological state and behavior of early weaning infants .
