<p><b>OBJECTIVE</b>To make a comparative study of HLA-DQA1 and HLA-DRB1 allele frequencies in the cases of endometriosis and adeonmyosis.</p><p><b>METHODS</b>The allelic types of HLA-DQA1 and HLA-DRB1 were detected by polymerase chain reaction-sequence specific primers (PCR-SSP) technique in 51 cases of endometriosis, 45 cases of adenomyosis, and 44 normal individuals as the control.</p><p><b>RESULTS</b>The frequencies of HLA-DQA1*0401(7.8%, 10.0%) were significantly increased in the endometriosis group and the adenomyosis group (Pc=0.03, Pc=0.01), and the frequencies of HLA-DQA1*0301(8.8%, 5.6%) were significantly decreased in these two groups (Pc=0.00, Pc=0.00).There was no significant difference between the frequencies of HLA-DQA1 and HLA-DRB1 of endometriosis and adenomyosis.</p><p><b>CONCLUSION</b>The results indicate that HLA-DQA1*0301 and *0401 alleles are associated with both endometriosis and adenomyosis, and there is perhaps common mechanism involved in both endometriosis and adenomyosis based on HLA-DQA1 and HLA-DRB1 allele frequencies.</p>

AIM: To investigate the association between HBV infection and HLA-DPB1 gene in population of Guangzhou Chinese. METHODS: 58 unrelated patients (test positive of HbsAg,HBeAg,HbcAb) and 75 unrelated healthy control individuals were typed by sequencing based typing (SBT) method in their HLA-DPB1 gene. RESULTS: The phenotype frequencies of HLA-DPB1 alleles of patients and control have no significant difference. CONCLUSION: These results indicate that there is no association between HLA-DPB1 gene and HBV infection.

Objective:To investigate HLA DQA1 alleles distribution in the Yichu of Yangbi county, Yunnan province, compared with other Chinese group Methods:PCR RFLP.Results: Of 8 DQA1 alleles studied, DQA1*0301 (allele frequency 31 63%) is the most common allele in this Yichu, and DQA1*0401 (1 02%) is the rarest Chi square test shows that Yangbi Yichu has no significant difference with six northern Han groups, Man, Singaporean and Uygurs of Xinjiang In contrast, Buyi, Dai and Taiwanese is much more complicated with a significant difference from other groups A similar observation was found in Guangdong Han and Guangxi Zhuang Similar to Kazak, Uygurs showed no significant difference with some of northern Han groups Tibetans have no significant difference with Kazaks and Singaporean Conclusion: DQA1 complexity of southern ethnic group is probably result of mutilple origin or stress of different environment Yangbi Yi ethnic group has characteristic of Northern group
