DAZL, a member of the DAZ family, plays a key role in human spermatogenesis. It regulates the promoter via genetic modification, especially DNA methylation, promoting the transcription of DAZL. Besides, the relation of DAZL SNPs with male infertility has been a hot spot of research for many years. It is deduced that local and ethnic factors may be associated with the failure of spermatogenesis. This article presents an overview on the results of recent studies, changes in the DNA methylation of DAZL in spermatogenesis, and the association of DAZL SNPs with male infertility, aiming to provide a new theoretical basis and clinical strategy for the treatment of male infertility.

OBJECTIVETo study the accuracy of the application of the intrapartum fetal oxygen saturation (FSO2) monitoring in predicting fetal acidosis and diagnosing intrauterine fetal distress.

METHODSContinuous FSO2 monitoring as well as internal and external fetal heart rate monitoring were applied respectively in 60 women in labor during active phase of the first stage and the second stage. All the monitoring methods were validated with standard sensitivity, specificity, positive predictive value, negative predictive value, and accuracy on the bases of Apgar score and cord artery blood analysis.

RESULTSThe mean FSO2 in the active phase of the first stage were significantly higher than in the second stage of labor. FSO2 correlated with pH, PO2, PCO2, and base excess (BE) of cord blood to a significant degree. There was linear correlation between FSO2 and cord artery blood pH. Using 30% cutoff diagnosing intrauterine fetal distress, the sensitivity, specificity, and accuracy were 80%, 100% and 98.3%, respectively.

CONCLUSIONFSO2 monitoring is an effective method diagnosing intrauterine fetal distress.

This study was purposed to construct a lentiviral vector carrying the TNF-related apoptosis-inducing ligand (TRAIL) gene and investigate its infection efficiency to several lymphoma cells lines. A pGM-T-TRAIL vector was constructed by inserting the cDNA segment derived from TRAIL mRNA into the cloning vector pGM-T, which was then inserted into the lentiviral vector pWPI. The recombinant lentiviral vector plenti-TRAIL was produced by transfecting 293T cells with pWPI-TRAIL, packaging plasmid Δ8.2, and envelope plasmid pCMV-VSVG and then harvested from the culture supernatant. Infection efficiency was measured in several lymphoma cell lines by live cell GFP fluorescence, while TRAIL expression was assessed by RT-PCR and Western blot. The results showed that the enzyme cut identification and sequencing demonstrated the successful construction of both pGM-T-TRAIL and pWPI-TRAIL. The results of testing drop showed that the concentration of the restructured lentiviral plenti-TRAIL reached 10(9) IU/ml. Comparison of infection efficiency revealed that YTS cells were more likely to be infected than DOHH2 or Jurkat cells (P < 0.05). Finally, RT-PCR and Western blot showed that lymphoma cells infected with plenti-TRAIL were able to efficiently express the TRAIL mRNA and protein. It is concluded that the lentiviral vector pWPI-TRAIL is successfully constructed and the recombinant lentiviral plenti-TRAIL is manufactured. The plenti-TRAIL vector is able to infect several lymphoma cell lines, and the infected lymphoma cells can effectively express TRAIL genes.
