ABSTRACT

<p><b>OBJECTIVE</b>To investigate the polymorphism of loci DXS6800, DXS6797, GATA172D05, DXS986 four loci in Hebei Han population.</p><p><b>METHODS</b>The genome DNA of unrelated individuals,the families and rotten materials were extracted with phenol-chloroform method and Chelex-100 method,respectively. The PCR products were detected by the polyacrylamide gel electrophoresis and DNA sequencing analysis.</p><p><b>RESULTS</b>Among 150 unrelated males and 150 unrelated females from Hebei Han population, 25 alleles were found in the 4 loci. One hundred and thirty-eight haplotypes of the male were detected. The haplotype diversity reached 0.9986.</p><p><b>CONCLUSION</b>The findings provided the polymorphic data of DXS6800, DXS6797, GATA172D05, and DXS986 loci in Hebei Han population.

ABSTRACT

<p><b>AIM</b>To detect the changes of inducible heme oxygenase (HO-1) expression in liver following ischemia/reperfusion (I/R) of hindlimbs and to elucidate their significance.</p><p><b>METHODS</b>I/R was established using the occlusion of the femoral arteries for 4h and reopening for 2-24 h in rats. The expression of HO-1 mRNA and HO-1 protein in liver tissue were detected with reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemical technique, respectively. The observation of pathologic changes of liver was made following the inhibition of HO-1 by zinc protoporphyrin (ZnPP).</p><p><b>RESULTS</b>Compared with control groups, the relative expression level of HO-1 mRNA significantly increased in I/R group. There were more HO-1 positive hepatocytes in I/R group than control groups. The pathologic changes of liver tissue became more severe in I/R + ZnPP group.</p><p><b>CONCLUSION</b>The expressions of HO-1 mRNA and protein in liver tissue are significantly upregulated, induction of HO-1 is involved in protection for hepatocytes during the I/R of hindlimbs.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the sequence polymorphism of mtDNA HV1,HV2 overlapping fragments and coding region encompassing position 8430-8673 in Hebei Han population.</p><p><b>METHODS</b>Polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) combined with sequencing method was used to detect the haplotype distribution of mtDNA in 100 Hebei Han individuals.</p><p><b>RESULTS</b>Ninety-one haplotypes were noted in 100 unrelated individuals. The gene diversity is 0.9985 and the random match probability is 0.0115. Compared with the Anderson sequence, 65 sites of different nucleotide sequences were noted, of which 44 sites were previously registered in MITOMAP, 12 sites were not registered and the gene mutations were different from MITOMAP at 9 positions.</p><p><b>CONCLUSION</b>The obtained data suggest that these loci are valuable genetic markers for personal identification and thus could be used as basic data for the forensic application of mtDNA in Hebei province.</p>

ABSTRACT

<p><b>AIM</b>To detect the changes of inducible nitric oxide synthase (iNOS) expression in liver following ischemia/reperfusion (I/R) of hindlimbs and to elucidate their significance.</p><p><b>METHODS</b>I/R was established using the occlusion of the femoral arteries for 4 h and reopening for 2-24 h in rats. The expression of iNOS mRNA, and iNOS protein and the nitrotyrosine (NT), a marker of peroxynitrite (ONOO-), in liver tissue were detected with reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemical technique, respectively. The liver superoxide dismutase (SOD) activity and malondialdehyde (MDA) contents were spectrophotometrically measured. The observation of pathologic changes of liver was made following the inhibition of iNOS by aminoguanidine (AG).</p><p><b>RESULTS</b>Compared with control groups, the relative expression level of iNOS mRNA significantly increased in I/R group. There were more iNOS positive hepatocytes and more NT positive hepatocytes in I/R group than control groups. The contents of MDA markedly increased, while the activity of SOD significantly decreased in I/R group, compared with those in the control groups. The pathologic changes of rat liver became milder in I/R group following the inhibition of iNOS by AG.</p><p><b>CONCLUSION</b>The expressions of iNOS mRNA and protein in liver are significantly upregulated, excess induction of iNOS-NO is contributed to the liver injury during the I/R of hindlimbs.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the distribution of the polymorphism of the Y-chromosomal loci DYS438, DYS439, GATA A7.1 and GATA A7.2 among Han population in Hebei province.</p><p><b>METHODS</b>With the use of PCR followed by polyacrylamide gel electrophoresis and silver staining, the allele frequencies of these loci in 164 unrelated men of Han population were investigated.</p><p><b>RESULTS</b>Four, five, five, four alleles were observed at the loci DYS438, DYS439, GATA A7.1 and GATA A7.2 respectively; the frequencies of these alleles ranged from 0.0359 to 0.6587, from 0.0179 to 0.4107, from 0.0122 to 0.4146 and from 0.0476 to 0.5238 respectively; the probability discrimination of these loci were 0.5121, 0.6811, 0.6679 and 0.6327 respectively. Seventy different haplotypes were found at these loci. Thirty-six different haplotypes appeared only once. The power of discrimination of these four loci was 0.9480.</p><p><b>CONCLUSION</b>The results demonstrate that these loci(DYS438, DYS439, GATA A7.1 and GATA A7.2) are good genetic markers with high determination power and can be applied to individual identification, especially in paternity test and the detection of mixed samples.</p>
