Correlation between body composition and serum lipid and uric acid in Maonan Guangxi population / 解剖学报

Objective To investigate the relationship between body composition and serum lipids and uric acid among adults in Maonan, and to analyze the effect of body composition changes on blood lipid and uric acid. Methods Totally 584 Maonan adult volunteers in Maonan village of Maonan Autonomous County in Guangxi, the age from 20 to 80 were recruited. The height was measured by the personal height tester; the body composition was measured by the ANITAMC-180 instrument; and the blood lipids and blood uric acid were measured by the Hitachi 7600 instrument. The obtained data were statistically analyzed by SPSS 20. 0. Results The age,height, weight, free fat mass, muscle mass, presumptive bone mass, body water, proptein,extracellular water, intracellular water, and waist-to-hip ratio were greater in Maonan men than in women (P<0. 05). However, whereas male fat content, body fat rate, and subcutaneous fat content were smaller than those of female (P < 0. 01). The total prevalence of hyperuricemia and hyperlipidemia in Maonan nationality was 13. 9% and 28. 4%, respectively. The prevalence of hyperuricemia and hyperlipidemia in males was higher than in females. In males, the body mass, body mass index, free fat mass, fat mass, muscle mass, presumptive bone mass, protein, extracellular water, body fat rate, visceral fat content, subcutaneous fat content and waist-hip ratio of the hyperlipidemia group were higher than the normal group (P<0. 05); and in females, the age, body mass index, fat mass, body fat rate, visceral fat content and waist-hip ratio of the hyperlipidemia group were higher than the normal group. In male, The body mass, free fat mass, presumptive bone mass, body water, extracellular water of the hyperuricemia group were higher than the normal group (P<0. 05); In females, the age, body mass, body mass index, fat mass, extracellular water, body fat ratio, muscle mass, visceral fat content, subcutaneous fat content, and waist-hip ratio of the hyperuricemia group were higher than the normal group. Conclusion The detection rate of hyperlipidemia and hyperuricemia in males of Guangxi Maonan nationality is all higher than that in females. The body composition is significant differences between the normal adults and the patients with hyperlipidemia and hyperuricemia of Maonan nationality in Guangxi.

Genetic analysis of Mulao nationality using 15 short tandem repeats / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To study the genetic polymorphism of 15 short tandem repeats (STR)(D2S1338, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D19S433, D21S11, CSF1PO, TPOX, TH01, vWA, FGA) in Mulao nationality of Guangxi province, and to explore genetic relationship between Mulao nationality and other 10 nationalities.</p><p><b>METHODS</b>The allelic frequencies and the genotype of 15 STR loci were generated from 183 unrelated individuals in Mulao nationality and other 10 nationalities of Guangxi by PCR-STR and genescan. Phylogenetic tree were constracted neighbor-Joining method.</p><p><b>RESULTS</b>There were 136 STR alleles and 422 genotypes in the 15 STR of Mulao nationality, with its allele frequencies ranging from 0.0027 to 0.5243. The average heterozygosity was 0.7632, the accumulative discrimination power was more than 0.999 999 999 9, and the probability of paternity exclusion was more than 0.999 998 469 8. The genetic distances between Mulao nationality and other minority of Guangxi were much closer than those between Mulao nationality and Han nationality and Uighur nationlity.</p><p><b>CONCLUSION</b>The 15 STR loci of Mulao nationality in Guangxi possesses the characteristics of high genetic diversity, except the TPOX locus. They can be employed in group genetic investigation, individual and paternity test in forensic medicine. The genetic distances between Mulao nationality and other minority of Guangxi are more closer than those between Mulao nationality and Han nationality and Uighur nationality.</p>

Genetic polymorphism of 6 short-tandem repeat loci in Miao minority group of Rongshui county in Guangxi province / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To investigate the distributions of six short-tandem repeat (STR) loci, namely D7S820, D13S317, D16S539, HUMCSF1PO, HUMTPOX and HUMTH01, in Miao minority group at Rongshui county in Guangxi province and construct the relevant genetic database.</p><p><b>METHODS</b>Sodium-citrated blood specimens were collected from 208 healthy unrelated Miao individuals in Rongshui county. The DNAs from the specimens were extracted with phenol-chloroform method; AmplFSTR Identifier PCR Amplification Kit was used to amplify the extracted DNAs, and 3100 Genetic Analyzer was used to analyze and screen the amplified products.</p><p><b>RESULTS</b>In this study, 7, 8, 6, 7, 5, 7 alleles were observed at the 6 STR loci respectively. The expected distribution of genotype accorded with Hardy-Weinbery equilibrium. The total discrimination power, cumulative paternity exclusion power and total polymorphism information were 0.999995, 0.9959 and 0.9987 respectively.</p><p><b>CONCLUSION</b>The results demonstrate that these 6 STR loci are of high polymorphism and hereditary stability and are in accord with Mendel's law.
