China Pharmacy 2007;0(29):-
OBJECTIVE:To evaluate the drug utilization and safe medication in gestational women in a hospital. METHODS: The drug utilization in 505 gestational women in a hospital from July 2007 to Jan. 2008 was investigated,with FDA's drug classification system during gestation as control. RESULTS & CONCLUSION: 35.84% of the patients received drugs during gestation;54.01% used drugs in the first 3 gestational months;56.15% used at least 2 kinds of drugs in combination;traditional Chinese medicine or Chinese patent medicines were the first choice for gestational women. The drug use for gestational women was prudent and basically in line with FDA's drug classification system during gestation;however,some drugs which pose risks for fetus were also used. There is as yet no guiding principle for safe medication of gestational women in China,thus it is imperative to establish safe drug use system for gestational women.

OBJECTIVETo establish a novel human monocytic leukemic cell line and characterize its biological features.
METHODSMononuclear cells isolated from the bone marrow of an acute monocytic leukemia (AML-M(5b)) patient at relapse were inoculated in a liquid culture system. And the biologic features of the established cell line SHI-1 were characterized by morphology, cytochemical staining, flow cytometry, karyotypic analysis, polymerase chain reaction (PCR), reverse transcriptase PCR (RT-PCR), fluorescence in situ hybridization (FISH), tumorigenicity in nude mice, quantitative fluorescent polymerase chain reaction, broth medium culture, short tandem repeating sequences-PCR (STR-PCR), multiplex-FISH (M-FISH), and (3)H-thymidine incorporation assay.
RESULTSA human acute monocytic leukemia cell line, SHI-1, was established and has proliferated continuously in vitro for over one year. The cell line presented typical morphology and immuno-profile of monocytic lineage with the original t(6;11)(q27;q23) and del(17)(p11) abnormalities. The MLL-AF6 fusion transcript was detected by RT-PCR. The rearrangement of MLL gene, deletion of p53 gene, and translocation between chromosomes 6 and 11 were revealed by FISH. A point mutation of ATC-->ACC at exon 6 of the p53 gene was found by sequencing of the PCR products. The clonality and the high tumorigenicity of the SHI-1 cell line were confirmed. Infections of EBV and mycoplasma were excluded. A derivative chromosome 7 resulting from a translocation between chromosomes 7 and 13, monosomy 18 and a minute derived from chromosome 8 in addition to t(6;11) and deletion(17)(p11) were detected by M-FISH in SHI-1 cells passaged to March 2003. Cell line authentication by STR-PCR confirmed the identity to the original leukemic cells of the patient. (3)H-thymidine incorporation assay showed that IL-4 and IL-15 had proliferative effects, while IFN-gamma, TNFalpha, IL-2, PDGF, and IL-7 had inhibitory effects on the cell line.
CONCLUSIONSSHI-1 is a novel acute monocytic leukemia-derived cell line carrying t(6;11)(q27;q23) and p53 gene alteration and having high tumorigenicity in nude mice. It provides a new useful tool for leukemia research.

OBJECTIVETo explore the feasibility of magnetic resonance cell imaging technology by using polyethylene imine (PEI)-coated magnetic nanoparticles of Fe₄O₄ (PEI-Fe₄O₄-MNPs) to track cell biology behavior.
METHODSEndocytic PEI-Fe₄O₄-MNPs in SHI-1 cells were observed by transmission electron microscopy (TEM) . Iron contents of nano-labeled cells were analyzed by inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and Prussian blue staining. The proliferation ability of labeled cells was detected by cell counting kit-8 (CCK-8) assay; the differentiation and colony-forming abilities were also observed. SHI-1 cells without endocytosing PEI-Fe₄O₄-MNPs were used as control.
RESULTSOur data showed that PEI-Fe₄O₄-MNPs could label SHI-1 cells. The labeling efficiency depended on the nanoparticles' concentration and the duration of cells treating. Inhibition rates of SHI-1cells labeled by 60-100 μg Fe/ml PEI-Fe₄O₄-MNPs were much higher than of 5-50 μg Fe/ml ones following treating by 5-100 μg Fe/ml PEI-Fe₄O₄-MNPs for 48 hrs. The expressions of CD11b and CD14 were (78.4±18.5)% and (18.7±2.9)% in control vs (83.3±14.2)% and (20.4±2.1)% in cells fractions treated by 30 μg Fe/ml PEI-Fe₄O₄-MNPs. Clony-forming rates of SHI-1 cells labeled by 0, 20 , 50 μg Fe/ml PEI-Fe₄O₄-MNPs were (25.20±7.22)%, (25.93±13.15)%, (23.37±9.33)%, respectively. Differentiation and colony-forming potentials of labeled cells were similar with control in the certain range of PEI-Fe₄O₄-MNPs concentration.
CONCLUSIONSHI-1 cells were efficiently labeled by PEI-Fe₄O₄-MNPs with well biocompatibilities in proper range of concentration, the latter could be coupled with magnetic resonance imaging (MRI) to track cells in vivo.
