RESUMO
Objective To establish regression m odel betw een craniofacial lines and body height by m ea-suring craniofacial lines in Southw est H an m ales using C Tand to accum ulate data for the study of foren-sic anthropology. Methods H ead C Tdata of 273 H an m ales in Southw est w ere collected and 7 cranio-facial lines w ere determ ined. M ultiplanar reconstruction and volum e rendering w ere perform ed by im age post-processing softw are and the selected lines w ere m easured. The relationship betw een each m easuring indicator and body height w as analyzed using SPSS 21.0 softw are. The regression equation of body height estim ation w as established and 50 sam ples w ere selected again and put into the m athem atics m odels to verify its accuracy. Results The linear regression equations of 7 lines w ere established (P<0.05). The correlation coefficients of the unary linear regression equations w ere 0.190-0.439 and the standard errors of the estim ate (SEE) w ere 4.597-5.023 cm . The correlation coefficients of the m ultiple linear regression equation w ere 0.494-0.524 and the SEEw ere 4.418-4.458 cm . The return tests show ed that the highest ±1SEEaccuracy of the m ultiple regression equation:y=83.959+3.589 x6+2.573 x2, w ere 30%;and the highest ±2SEEaccuracy of the m ultiple regression equation: y=72.646+3.316 x6+1.586 x2+1.553 x4+2.211 x3, w ere 92% . Conclusion There is significant linear correlation betw een 7 selected lines and the stature in this study, and the plural linear regression equation established could be applied for estim ating the stature of Southw est H an m ales.
RESUMO
Objective To investigate the genetic polym orphism s of 21 autosom al STR loci of Fujian H an population and evaluate the forensic application value of GlobalFilerTM E xpress kit. Methods A m plified w ith GlobalFilerTM E xpress kit, DNA sam ples were obtained from 741 unrelated individuals of Fujian H an population. The population genetics param eters of 21 autosom al STR loci were calculated. Results The 21 autosom al STR loci were found to be no deviation from Hardy-Weinberg equilibration (P>0.05) and relatively abundant in high polym orphism . H eterozygosity ranged from 0.589 to 0.914, pow er of dis-crim ination ranged from 0.754 to 0.992, polym orphic inform ation content ranged from 0.520 to 0.940, and pow er of exclusion ranged from 0.278 to 0.825. The SE33 locus was the highest degree in poly-m orphism . Conclusion The 21 STR loci of GlobalFilerTM E xpress kit have high value in discrim ination pow er and can be useful in personal identification and paternity test in Fujian H an population.
