Objective To study the rate of mother-to-child transmission (MTCT) on HIV-1. Methods All local residents from 8 townships in a region were screened for mothers who had a history of only one blood transfusion and 63 were found HIV-1 positive. A further study on these HIV-1 positive mothers and their children was conducted with the emphasis on the date of receiving blood transfusion, date and type of nationality, history regarding breastfeeding and so on. Sera specimens from 84 children born from 63 HIV-1 positive mothers were screened, using ELISA for HIV-1 antibody, and positive specimens were confirmed by Western-blot. Results The rate of MTCT was 32.1% (27/84) for children with all risk factors related to MTCT. Another 36.8% (7/19) were related to factors on intrauterine, intrapartum and breastfeeding, 35.7% (5/14) to intrapartum and breastfeeding factors, 14.3% (2/14) to intrauterine and intrapartum factors, 37.9% (11/29) to breastfeeding factor alone. By group combination analysis, the MTCT rate was 36.9% (24/65) with breastfeeding, 11.8% (2/17) with artificial feeding, and the former was significantly higher than the latter. Conclusion HIV-1 MTCT rate among mothers caused by a single blood transfusion varied with different risk factors. Breastfeeding played an important role in MTCT, appeared in our study.

Objective To study epidemiological features of HIV infection after blood transfusion and the situation of transmission among members of family.Methods The persons infected with HIV through blood transfusion and their intrnfamilial transmission in some city were analyzed and testing methods of ELISA,Western-blot,RT-PCR and subtype analyzing were used.The whole surveillance data came from residents investigation around problem medical centres and HIV monitoring network around Hebei province.Results 173 people infected with HIV after blood transfusion in some city.including 89 cases found in hospital and 84 cases in CDC,accounted for 68.7%(173/252)of all of infected persons by blood transfusion in Hebei province.The rate of intrafamilial transmission,spousal transmission and mother-to-child transmission((MTCT)were 32.0% (49/153),17.0%(26/153)and 32.7%(32/98),respectively.Most of persons infected with HIV were youth among who the female were more than the male.Childbearing and women's ailments were the main cause of blood transfusion from 1990 to 1999,and traumatism surgery took second place.Infected persons by HIV blood,whose time to diagnostic were the year from 1999 to 2009,spread over Kangtai hospital and other hospital which accounted for 45.1%(78/173)and 42.2%(73/173),respectively.The genetype of all patients were B'subtype.Conclusion The medical centers at the grass-roolg level in some city resuhed in outbreak of infected persons bv HIV blood because of having no screening test antibody of HIV fur paid blood donors.

To study the molecular mechanism of the effect of fibroblastoid stromal cells (HFCL) from human bone marrow on the proliferation and differentiation in acute myeloid leukemia HL-60 cells, the cell cycle was analyzed by flow cytometry (FCM); the cell differentiation was determined by morphology NBT test and flow cytometric detection for expression of CD11b, CD14, CD13 and CD33; the genes differently expressed between HL-60 cells and HL-60 cells directly cocultured with HFCL were detected by using Affymetric oligo microarray technique. The changes of expression in some key genes were confirmed by using RT-PCR and Northern blot. The results showed that the percentage of G(1) phase cells in AML cells cocultured with HFCL cells was higher than that without HFCL cells, and the percentage of S phase cells was lower. The NBT positive cells and the expression of CD11b and CD14 increased. It was found that after direct contact of HL-60 cells with HFCL cells for 96 hours, the expression levels of 582 genes were up-regulated, 1 323 genes down-regulated. It is concluded that many genes may take part in the influence of HFCL cells on HL-60 cells, which may give important insights into the important molecules and pathways or cross-talk involved in the interaction between the AML cells and stromal cells.

This study was aimed to detect the gene expression profile changes between human acute leukemia cell line HL-60 and VCR-resistance HL-60, and to investigate the underlying mechanisms of MDR by using genechip technology. In experiments, mRNA were harvested using TrizoL reagent from these two cell lines, through RT-PCR, the biotinylated nucleotide were incorporated into the cRNA during the in vitro transcription reaction. The high quality RNA was hybridized to the gene expression array--human genome U133A developed by Affymetrix. It was scanned by G2500A GeneArray Scanner and the acquired image was analysed by a series of softwares. The results showed that 5,507 genes were differentially expressed between human acute leukemia cell line HL-60 and VCR-resistant HL-60. Compared with HL-60, 3,100 genes were up-regulated and 2,407 genes were down-regulated in VCR-resistant cell line. These genes were involved in different cell activities such as growth regulation and signal transduction. Among the genes with remarkable differential expression between the two cell lines, 435 were up-regulated and 605 were down-regulated. It is concluded that many different kinds of genes are involved in the mechanism of MDR and there is an intricate molecular network that controls the sensitivity of leukemia cells to the chemotherapeutic agents. Genechip is an efficient tool for parallel gene expression analysis.
