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 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 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.

Chronic myeloid leukemia (CML) is a malignant clonal disease derived from hematopoietic stem cells. CML stem cells were thought to be the root which could lead disease development and ultimately rapid change. However, a stable animal model for studying the characteristics of CML stem cells is currently lacking. This study was aimed to establish a transplanted human CML nude-mice model to further explore the biological behavior of CML stem cells in vivo, and to enrich CML stem cells in nude mice by series transplantation. The 4 - 6 weeks old BALB/c nude mice pretreated by splenectomy (S), cytoxan intraperitoneal injection (C) and sublethal irradiation (I) were transplanted intravenously with (5 - 7) × 10(7) of bone marrow mononuclear cells from CML patients in chronic phase. Alternatively, 4 - 6 weeks old BALB/c nude mice pretreated by lethal irradiation were transplanted intravenously with 5 × 10(6) homologous bone marrow cells of BALB/c nude mice together with (5 - 7) × 10(7) of bone marrow mononuclear cells from CML patients in chronic phase simultaneously. The leukemic cells engrafted and infiltrated in organs and bone marrow of the mice were tracked by reverse transcription-polymerase chain reaction (RT-PCR), plastic-embedded biopsy and flow cytometry. The results of these two methods were compared. The results showed that human CML cells engrafted and infiltrating into the bone marrow of two nude mice pretreated with SCI could be detected. In spite of the low successful rate, results suggested the feasibility of this method by using BALB/c nude mice as a human CML animal model. In contrast, in nude mice pretreated by the lethal dose irradiation, CML cells in the bone marrow could not be found. It is concluded that human bone marrow CML cells can results in leukemia in nude mice pretreated by SCI. Thus this study provides a new strategy for establishment of CML animal models which deserves further elaboration.

OBJECTIVETo study the expression of CXCR4 in acute leukemic cells and its clinical significance.
METHODBone marrow samples from 73 acute leukemia patients and leukemic cell lines were investigated by flow cytometry (FCM), the expression of SDF-1 in human marrow stromal cells and meninges were studied by using reverse transcription polymerase chain reaction (RT-PCR). Adhesion, migration and invasion of U937, NB4 and K562 cells were studied in vitro.
RESULTSThe expression rates of CXCR4 in ALL and AML patients was 65.6% and 17.1%, respectively. And it was 0.2%, 41.0% and 52.0% in K562, U937 and NB4 cells, respectively. The extramedullary infiltration rates were 61.9% and 18.2% for CXCR4 positive and negative groups of ALL, respectively (P < 0.05); while in AML, the number of peripheral white blood cells in CXCR4 positive group was lower than that in CXCR4 negative group (P < 0.05). SDF-1alpha could enhance the adhesion, migration and invasion capacity of leukemic cells in vitro.
CONCLUSIONOverexpression of CXCR4 in AL cells might be the molecular mechanism of extramedullary infiltration in leukemia.

OBJECTIVETo investigate the effects of tributyrin (TB), a histone deacetylase inhibitor, on the growth, differentiation and apoptosis of SHI-1 leukemia cells and explore its possible mechanism.
METHODCell proliferation and viability were determined by cell counting, trypan blue dye exclusion. Cell morphological analysis, Annexin binding, DNA electrophoresis, expression of CD11b and CD14, NBT reduction were performed to evaluate differentiation and apoptosis of SHI-1 cells. The level of acetylated histone H3 was detected by Western blot and p21(WAF1/CIP1) expression by semi-quantitative RT-PCR.
RESULTSTB inhibited the proliferation and viability of SHI-1 cells in a time-dose dependent manner. The morphology of SHI-1 cells cultured in the presence of 0.1 mmol/L TB for 72 hs was more mature with higher NBT positivity and up-regulated expressions of CD11b and CD14 than that of control group. Exposed to 0.5 - 1.0 mmol/L TB for 48 hs, SHI-1 cells exhibited the morphological hallmarks of apoptosis, the increasing of Annexin binding and the DNA ladder on gel electrophoresis. The level of acetylated histone H3 and p21(WAF1) mRNA extracted from SHI-1 cells were increased by the treatment of TB.
CONCLUSIONTB can inhibit proliferation, induce differentiation and apoptosis of SHI-1 cells. The mechanism may associate with its up-regulation of acetylated histone and the expression of p21(WAF1).
