Objective To study whether myeloperoxidase (MPO) can provide prognostic information in patients with acute coronary syndromes (ACS). Methods The study population consisted of 274 consecutive patients with ACS. All patients underwent coronary angiography which showed significant coronary artery disease and blood samples were collected at admission. Follow-ups were scheduled at 1, 3, and 6 months.The end point included cardiac death, acute myocardial infarction (MI), percutaneous or surgical revascularization. Results Patients with elevated MPO serum levels (MPO ≥ 72.2 AUU/L) were more likely to have diabetics and had a history of coronary events. Kaplan-Meier event rate curves with accumulative incidence of end point at 6-month follow-up in the MPO ≥ 72.2 AUU/L group was significantly higher than in MPO<72.2 AUU/L group. Conclusions MPO may be a powerful predictor of adverse outcome in patients with ACS.

OBJECTIVETo investigate the influence of Rehmannia glutinosa oligosaccharides (ROS) on the proliferation of 3T3-L1 adipocytes and insulin resistance.
METHOD3T3-L1 preadipocytes were cultured, the proliferation of 3T3-L1 preadipocytes was detected by MTT method. Insulin resistant 3T3-L1 adipocytes cell model was induced by dexamethasone and the change of glucose concentration in cell culture was determined after ROS treatment.
RESULTIn the high glucose DMEM culture media, MTT method showed that the absorbance at 570nm of 3T3-L1 preadipocytes was increased and that of 3T3-L1 adipocytes was decreased. ROS significantly increased glucose consumption in 3T3-L1 preadipocytes and adipocytes culture in a concentration-dependent manner. ROS improved the sensitivity of 3T3-L1 adipocytes to insulin.
CONCLUSIONROS can promote the proliferation of 3T3-L1 preadipocytes, inhibite the proliferation of 3T3-L1 adipocytes, and also, significantly improve insulin resistance induced by dexamethasone.

OBJECTIVETo find out the risk factors of drowning among children aged 1 and 14 in rural areas and to provide evidence for prevention and to reduce such incidents.
METHODS20 towns being selected as a cluster sampling study and screened out 133 drowning children aged 1-14 from Jan. 1, 2002 to Dec. 31, 2004 were screened. 1:2 matched case-control method was conducted. Data was analyzed with conditional univariate and multivariate logistic regression analysis.
RESULTSResults showed that falling into water took the leading type of drowning among children from the rural areas. The component of drowning displayed that boys was higher than girls. The majority occurred. during the warmer months, in summer and autumn. The places where drowning occurred was mainly at incidence site. Results from single and multiple factors analysis identified four major risk factors as: alcoholic drinking of his/her mother, lack of emergency treatment in the village, the child care-taker did not know what to do when drowning was occurring, the child usually played beside the water site. Factors preventing from drowning were: swimming training, the child caretaker keeping an eye on the child when he/she was swimming, the health condition of the caretaker and the communication with the parents.
CONCLUSIONThe risk factors of drowning among children aged 1-14 in rural areas were caused by multiple factors. Prevention and control program on drowning should be focusing on supervision, safety water, safety education and teaching swimming.

OBJECTIVETo explore the effect of down-regulation of insulin-like growth factor binding protein 7 (IGFBP7) on the proliferation and invasiveness of leukemia cell line U937 cells.
METHODSThree pairs of double-strand siRNA targeting IGFBP7 gene were transfected into SMMC7721 cells to select the most efficient one for U937 cells. qRT-PCR and Western blot were used to detect the expression of IGFBP7 in U937 cells after transiently transfected with siRNA of IGFBP7. Cell proliferation, adhesion, trans-endothelial migration and invasion were performed in transfected cells and control groups.
RESULTSAfter transfected with siRNA of IGFBP7 in U937 cells, the ability of cell proliferation was significantly decreased at 24 h (0.580 ± 0.159) compared to that of parental cells and scramble negative control (1.049 ± 0.274, 0.946 ± 0.195, respectively) (P < 0.01). Adhesion of U937 cells transfected with IGFBP7 gene specific siRNA to ECV304 cells was significantly lower than that of the control groups (0.247 ± 0.031 vs 0.406 ± 0.023 and 0.395 ± 0.011) (P < 0.01). Transendothelial membrane of U937 cells into the bottom of the 24-well plate for experimental group were less than those in the control groups \[(0.387 ± 0.021)×10(5) vs (1.017 ± 0.031)×10(5) and (0.908 ± 0.027)×10(5)\]. Cells adherent to the matrigel for experimental group were less than those in the control groups \[(0.197 ± 0.098)×10(5) vs (0.493 ± 0.067)×10(5) and (0.469 ± 0.083)×10(5)\]. The difference was significant (P < 0.01).
CONCLUSIONIGFBP7 gene plays a contributing role in leukemogenesis involving in leukemic cells' proliferation and interaction with endothelial cells through adhesion, invasion and migration.

The aim of this study was to construct venus vector carrying the gene encoding insulin-like growth factor binding protein 7 (IGFBP7), which provides an effective platform for exploring the function of this gene in leukemia. After digestion by restriction endonuclease, the IGFBP7 gene was recombined with the transfer plasmid. The venus particles were packaged using 293T cells to transfect K562 cells, and identification was performed by means of flow cytometry, RT-PCR and Western blot. The results showed that the sequence of cloned IGFBP7 gene was the same as that in GenBank. The size of product restricted by BamHI was same as the predicted one. GFP expression was observed in 293T and K562 cells with the fluorescent microscopy and flow cytometry. The expression level of mRNA and protein of IGFBP7 was confirmed by RT-PCR and Western blotting in K562 cells. It is concluded that venus vector carrying IGFBP7 gene has been successfully constructed and provides basis for exploring function of IGFBP7 in K562 cells.

OBJECTIVETo explore the effects of anti-CD44 monoclonal antibody-IM7 on the in vitro adhesion and migration of chronic myeloid leukemia stem cell (CML-LSC) and its mechanism.
METHODSCD34(+)CD38(-)CD123(+) leukemic stem cells (LSC) from 20 newly-diagnosed chronic myeloid leukemia (CML) patients BM cells and CD34(+)CD38(-) hematopoietic stem cells (HSC) from 20 full-term newborn cord blood cells were isolated with EasySep(TM) magnet beads. The CD44 expression of the LSC and HSC was detected by flow cytometry (FCM), and the adhesion and migration ability of the LSC and HSC pre- and post-incubated with IM7 in vitro by MTT assay and transendothelial migration assay, respectively.
RESULTS(1) After incubated with IM7, the LSC and HSC CD44 expression rates were (86.60 ± 2.10)% vs. (25.40 ± 1.70)% (P < 0.05), respectively. (2) The adhesive ability of the LSC to endothelial cells was decreased markedly after incubated with IM7, the OD value (A(570)) changing from pre-incubation of (0.62 ± 0.11) to post-incubation of (0.34 ± 0.07), while there was little change of A(570) in the HSC group. (3) The migration ability of the LSC group was inhibited evidently after incubated with IM7, the inhibition rate being 46% ∼ 63%, while little change of that in HSC group was detected. (4) The adhesive ability of the LSC group to marrow stromal cells was decreased markedly after incubated with IM7, while little change was found in that of HSC group.
CONCLUSIONThe anti-CD44 monoclonal antibody-IM7 can effectively inhibit the adhesion and migration abilities of the LSC in vitro, which might provide a theoretical evidence for targeting therapy.
