A new method for noninvasive prenatal diagnosis of fetal sex was developed by using single cell PEP PCR techniques. Micromamipulation techniques were used to obtain single fetal cells from 273 maternal blood samples. The genome of single cells was preamplified by PEP and SRY genes were analyzed by PCR method. The SRY genes of 149 samples were detected by the new method among 153 samples carrying male fetus, while 119 out of 120 samples carrying female fetus were proved negative for SRY genes. The sensitivity and specificity of the new method were 97.39 % and 99.17 % respectively and the correct rate was 98.17 %. The new method has the advantage of high sensitivity and specificity in noninvasive prenatal diagnosis of fetal sex and provides the basis of other researches such as sex linked inherited diseases.

To explore the application of fetal DNA in maternal plasma for noninvasive prenatal diagnosis, the DNA template was extracted by hydroxybenzene chloroform from 44 maternal (7-41 weeks) plasma. The Fetus derived Y sequence DYZ 1 gene (149bp) was chosen to be amplified by PCR. The fragment was identified in all the plasma of male bearing pregnant women with the diagnostic accordance rate being 100.00 %. Two of the 22 female bearing pregnant women had false positive results. Among the 44 pregnant women, the diagnostic accordance rate was 88.89 % at early pregnant stage, 100.00 % at medium pregnant stage, and 96.55 % at late stage respectively. The final accuracy of 95.45 % was obtained in all cases. It was concluded that by means of hydroxybenzene chloroform extraction the authors of this article promoted the concentration and purity of the DNA template, and diagnosed more accurately. The results showed that free fetal DNA in the maternal plasma could be regarded as the gene resource for noninvasive prenatal diagnosis.

Background DNA analysis has shown a lack of significant compatibility between couples affected by unexplained recurrent spontaneous abortion (URSA) compared with normal fertile couples, 8 although one study that made use of a PCR-sequence-specific oligonucleotide (SSO) method did observe evidence of significant compatibility in the HLA-DQA1 and DQB1 alleles between patients and aborted fetuses. 9 This study was designed to investigate whether URSA were associated with particular DQ alleles or promoter *** Thirty-two patients with URSA and 54 women who had had at least one successful pregnancy were included in this study. HLA-DQ genotyping was performed by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The HLA-DQB1 promoter was detected by the SSO and sequence-specific primer (SSP) methods. The DQA1, DQB1, and DQB1 promoter (QBP) gene frequencies in the patients were compared with the gene frequencies in normal controls. The data were analyzed statistically with the χ 2 and Fisher’s exact *** The results showed that the frequency of DQB1 *0604/0605 was significantly higher and the frequency of DQB1 *0501/0502 was significantly lower in the patient group as compared with the normal controls. In addition, the frequencies of the DQA1 *01-DQB1 *0604/0605 and QBP6.2-DQB1 *0604/0605 haplotypes were overrepresented in the patients relative to the controls. Our results did not show any differences between URSA patients and the controls with regard to DQA1 and QBP allele frequencies. Conclusions Our data suggest that URSA is associated with the HLA-DQB1 coding region, and is not associated with its upstream regulatory region. The DQB1 *0604/0605, DQA1 *01-DQB1 *0604/0605, and QBP6.2-DQB1 *0604/0605 haplotypes may confer susceptibility to URSA, while the DQB1 *0501/0502 allele may protect women from URSA.
