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.

This study was purposed to explore the tumorigenicity of a novel human monocytic leukemic cell line SHI-1 in nude mice and its mechinism. The tumorigenicity in mice was evaluated in sixteen nude mice subcutaneously injected with the SHI-1 cell line. The tumor specimen was studied by the conventional pathologic examination. The mononuclear cells (MNC) of the tumor was assayed by RHG banding, the transcription of MLL-AF6 fusion gene and the VEGF gene was detected by RT-PCR. Gelatin zymography method was used to study the expression of MMP-9 and MMP-2 in the supernatant of the SHI-1 cell line. Matrigel invasion assay was employed for the study of migration of the SHI-1 cell in vitro. The results showed that the tumor masses were found in all sixteen mude mice after subcutaneous injection of SHI-1 cells, the tumor mass was mainly composed of leukemia cells, the transcription of MLL-AF6 fusion gene and VEGF gene was proved by RT-PCR analysis, the expressions of MMP-2 and MMP-9 in the serum-free culture supernatant of the SHI-1 cell line were significantly higher than those in U937, K562, and NB4 cell lines. The SHI-1 cell line exhibited significantly higher in vitro invasiveness than other leukemia cell lines, the blocking antibody of MMP-2 could inhibit the migration of the SHI-1 cell line significantly. It is concluded that the SHI-1 cell line presents higher tumorigenicity in nude mice than other leukemia cell line and the mechanism is associated with p53 gene alteration, high transcription level of VEGF gene, high expression level of MMP, and significantly higher invasiveness.

OBJECTIVETo explore early diagnosis of hemophagocytic syndrome (HPS) and effective treatment.

METHODSA multicenter retrospective study was carried out to analyze the causes, clinical features, laboratory findings, treatment and clinical outcomes of 72 patients with HPS.

RESULTSAmong the 72 patients, EBV infection and T lymphoma were the most common initiating diseases. The most common clinical features were persistent fever (100%) and splenomegaly (83.3%). The diagnostic sensitivity was persistent fever (100%), peripheral cytopenia in two or more lineages (97.2%), high concentration of serum soluble CD25 (93.1%) and low NK cell activity (94.4%). The median percentage of serum glycosylated ferritin was significantly lower in patients in HPS group \[(17.4 +/- 16.0)%\] than in control group \[(53.6 +/- 13.3)%\] (P < 0.01). And the median level of serum TNF-alpha was significantly higher in patients group \[(143.2 +/- 64.8) microg/L\] than in controls \[(66.9 +/- 19.4) microg/L\] (P < 0.01). Hepatic dysfunction was seen in most patients (83.6%) mainly manifested as elevated liver enzymes and hypoalbuminemia. The 15-week total survival rate was 46.8% in 47 treated patients, and was 63% in 27 treated with fludarabine in combination with high dose methylprednisolone. The platelet count and fibrinogen level were significantly lower in death group than in survival group.

CONCLUSIONSThe diagnostic sensitivities of presistent fever, peripheral cytopenia in two or more lineages, high concentration of serum soluble CD25 and low NK cell activity are relatively high and lacking hemophagocytosis does not exclude the diagnosis. Low percentage of glycosylated ferritin and high concentration of TNF-alpha would be helpful to the diagnosis. High dose methylprednisolone combined with fludarabine is an effective therapy. Platelet count and fibrinogen level are poor prognostic factors for HPS.
