Identification of A Novel HLA Allele DRB1 * 16:36 by Sequencing-Based Typing / 中国实验血液学杂志

<p><b>OBJECTIVE</b>To identify a novel HLA allele DRB1 * 16:36 from a Uygur woman.</p><p><b>METHODS</b>PCR-SBT technology was applied to the extracted DNA for genotyping, and a possible new gene was sequenced by using sequence specific primers and single stranded SBT. This novel allele was compared with known most homologous gene sequences and their difference was analyzed.</p><p><b>RESULTS</b>This novel allele was different from HLA alle DRB1 * 16:23, and had highest similarity in 2 nucleotides at position 227 A→T and 236 T→C in exon 2, resulting in 3 amino acid changes from Tyr to Phe at codon 47 and Val to Ala at codon 50. The sequence of this novel allele had been submitted to GenBank.</p><p><b>CONCLUSION</b>This HLA allele DRB1 * 16:23 has been confirmed to be a novel allele, and has been officially named DRB1 * 16:36 by the World Health Organization (WHO) Nomenclature Committee in May 2015.</p>

A case-control study on risk factor of Kaposi's sarcoma in Xinjiang / 中华流行病学杂志

<p><b>OBJECTIVE</b>To analyse related risk factors of classic Kaposi' s sarcoma in Xinjiang.</p><p><b>METHODS</b>A 1:4 case-control study was used and the conditional logistic regression model was performed in this study. Cases were followed up in Xinjiang while controls were selected by the same sex, nation and age within 5 years with cases.</p><p><b>RESULTS</b>Interleukin-6,vascular endothelial growth factor, beta-MG, neopterin, human herpevirus 8, were found to be associated with Kaposi's sarcoma risk in one-way variance model while beta2 -MG and human herpevirus 8 entered the multiple conditional logistic regression model, and their ORs were 1.002(95%CI: 1.000-1.003), 81.041 (95%CI: 1.790-3669.620).</p><p><b>CONCLUSION</b>There was a correlate relationship between beta2 -MG and classic Kaposi's sarcoma being found that human herpevirus 8 exposure related factors seemed to have played important roles on classic Kaposi's sarcoma in Xinjiang.</p>
