AIM:To investigate the myocardial protective effect of endometrial stem cell ( EnSC)-derived cyto-kine cocktail ( EdCC) on myocardial ischemic reperfusion injury and the MEK-ERK signaling pathway.METHODS: A mouse model of myocardial ischemic reperfusion injury was established.Infarct area, cell apoptosis, and expression of cleaved caspase-3 and phosphorylatied ERK1/2 were determined by TTC/Evans blue staining, TUNEL assay and Western blot, respectively.RESULTS:The mesenchymal characteristics were observed in the EnSCs with expressing CD90 and in absence of CD34 and CD45.EdCC contained (6 811 ±312) ng/g epidermal growth factor (EGF) protein.The phospho-rylation of ERK1/2 markedly increased after injection of EdCC, but was abolished by MEK1 inhibitor PD98059 ( 5 mg/kg) .EdCC decreased the infarct area and apoptotic cell number in the border zone and inhibited caspase-3 activation. However, the effects were abolished by MEK1 specific inhibitor PD98059.EGF did not decrease the infarct area, but the EGF receptor antagonist AG-1487 (6 mg/kg) partly abolished the myocardial protective effect of EdCC.CONCLUSION:EdCC protects the myocardium from ischemic reperfusion injury via activating MEK1-ERK signaling pathway, indicating an essential role in the transmission of stem cell therapy from the cell transplantation to cytokine based strategy.

Objective To identify risk factors and preventive measures of nosoconial infections in patients with non-Hodgkin lymphoma (NHL). Methods Clinical data of 65 NHL patients admitted from January to December 2007 were retrospectively analyzed. Results According to WHO classification (2001), 58 patients were with B-cell lymphoma, 7 were with T-cell lymphorna. All patients received CHOP regimen as initial chemotherapy and 23 of them were with nosecomial infections. Logistic regression analysis demonstrated that age, length of stay, pathological type, bone marrow involvement, levels of serum lactate dehydrogenase (LDH), beta2-microglobulin and invasive treatment were identified as risk factors of nosocomial infections. Respiratory tract infections and infections with gram-negative microorganisms were the most popular. Conclusion High nosocomial infection rate is found in NHL patients, and control of risk factors may effectively prevent nosocomial infections in NHL patients.

OBJECTIVETo investigate the protect effects of sodium ferulate (SF) on the daunormbicin(DNR-induced cardiotoxicity in juvenile rats.
METHODSForty male juvenile SD rats were randomly divided into control group (Control), daunorubicin group (DNR), sodium ferudate treatment group (DNR + SF), sodium ferudate group (SF) (n = 10) . Juvenile rats were intraperitoneally treated with DNR (2.5 mg/kg every week for a cumulative dose of 10 mg/kg) preparation immature myocardial injury model in presence with SF (60 mg/kg) oral treat- ment for 25 days. The left ventricular pressure and its response to isoproterenol were measured using left ventricular catheter. Rat myocardium myocardial pathology specimens and ultrastructure changes were also observed. The expression of cardiac Troponin I (cTNI) was detected by Western blot and RT-PCR. Results: SF treatment could inhibit the decreasing of heart rates induced by DNR damage (P < 0.05); it could increase the left ventrivular end diastolic pressure(LVEDP), heart rate, the maximal left ventrivular systolic speed(LVP + dp/dtmax) and the maximal left ventrivular diastolic speed (LVP-dp/dtmax) responding to isoproterenol stimulation(P < 0.01); SF also could improve the myocardial ultrastructure injuries and inhibit the decreasing of cTNI expression caused by DNR damages (P < 0.05).
CONCLUSIONSF treatment could alleviate the decreasing of cardiac reservation induced by DNR damages in juvenile rats, which might be related to its reversing the effects on the cardiac systolic and diastolic function injuries and its inhibiting effects on the decreasing of cTNI expression caused by DNR. The mechanism of SF preventing daunorubicin-induced cardiotoxicity in juvenile rats is relevant to inhabited cardiac Troponin I expression.

OBJECTIVETo investigate the effect of Busheng Huoxue Capsule (BHC) on the quality of life (QOL) in senile male osteoporosis (OP) patients, and to explore its mechanisms.
METHODSTotally 200 senile primary OP patients were randomly assigned to two groups according to random digit table method, 100 in each group. Patients in the treatment group took BHC plus caltrate-D (600 mg CaCO3), while those in the control group took alendronate (70 mg per week) plus caltrate-D. The therapeutic course was 12 months for all. Chinese medical symptom score and quality of life (QUALEFFO-41) score, bone mineral density (BMD) of lumbar vertebra (L2 -L4) and left femoral neck were compared between the two groups before and after treatment. Serum free testosterone (FT) and estradiol (E2) were also measured.
RESULTSChinese medical symptom scores and QUALEFFO-41 scores, serum FT and E2 levels increased in the two groups after treatment (P < 0.05, P < 0.01). The therapeutic effect was superior in the treatment group (P < 0.05, P < 0.01). After treatment the BMD of lumbar vertebra (L2 -L4) and the left femoral neck were somewhat improved (P < 0.05), but with no statistical difference between the two groups (P > 0.05).
CONCLUSIONBHC could effectively improve the QOL of senile male OP patients, which might be correlated with elevating the BMD levels and regulating the levels of sex hormones.

Objective To investigate whether homocysteine(Hcy) induces apoptosis of endothelial cells via a pathway involving caspases3 and whether simvastatin antagonizes the proapoptotic effects of Hcy by regulating c-IAP. Methods Human umbilical vein endothelial cells(HUVEC) were treated with Hcy,with or without simvastatin,for 24 h.Cell apoptosis was evaluated by Annexin V staining and flow cytometery,as well as TUNEL.The mRNA and protein levels of caspase3,c-IAP-1 and c-IAP-2 were analyzed by RT-PCR and Western blot,respectively. Results Treatment with both low(0.5 mmol/L) and high(3.0 mmol/L) concentrations of Hcy-induced HUVEC apoptosis was accompanied by an increased level of caspase3 expression and activation,together with decreased c-IAP-1 and c-IAP-2 level.Simvastatin upregulated c-IAP-1 and c-IAP-2 expression while attenuated Hcy-induced apoptosis and caspase3 activation. Conclusion Hcy may induce HUVEC apoptosis via a pathway involving caspase3,which can be partially antagonized by simvastatin,possibly through upregulated c-IAP-1 and c-IAP-2 expression.
