AIM:To elucidate whether ZFP580 is involved in the cardioprotective effects of hypoxic precondi-tioning (HPC) against hypoxia-reoxygenation (H/R) injury in H9c2 myocardial cells.METHODS: Rat heart-derived H9c2 cells were cultured in DMEM .H/R was induced by incubation under ischemic hypoxia for 3 h and reoxygenation for 2 h.HPC was induced by exposing the H 9c2 cells to 10 min of hypoxia and 20 min of reoxygenation for 3 cycles before H/R treatment.MTT staining and LDH leakage detection were used to evaluate the effects of HPC .Western blotting was used to detect the protein levels of ZFP580, phosphorylated ERK1/2 and cleaved caspased-3.The effects of ZFP580 overexpre-ssion or knockdown on H/R induced apoptosis were determined .RESULTS:The results of MTT staining and LDH leakage detection showed evidence of HPC cytoprotection against H /R-induced cell death in H9c2 cells.ZFP580 protein level and ERK1/2 phosphorylation were significantly increased in the HPC group compared with control group and H /R group. PD98059, an inhibitor of ERK1/2 phosphorylation , significantly suppressed the HPC-induced up-regulation of ZFP580 pro-tein expression.ZFP580 overexpression significantly inhibited apoptosis and caspase-3 activation in H9c2 cells.CON-CLUSION:HPC exhibits cytoprotection against H/R and leads to high level of ZFP 580 protein in H9c2 cells.ZFP580 is regulated by ERK1/2 activation and mediates the anti-apoptotic effect of the ERK1/2 signaling pathway in HPC cytoprotec-tion.

BACKGROUND: Bone marrow mesenchymal stem cells are characterized by wide sources and low immunogenicity. Especially, these cells are easy to import and express foreign genes, and thus have obvious superiorities as anti-tumor gene therapy vectors. OBJECTIVE: To investigate the effects of interleukin-12 gene modified bone marrow mesenchymal stem cells on the proliferation, cell cycle and apoptosis of ovarian cancer cells. METHODS: Interleukin-12 recombinant adenovirus vector was used to transfect bone marrow mesenchymal stem cells. Then, the expression of interleukin-12 mRNA and protien in transfected bone marrow mesenchymal stem cells was detected by RT-PCR and western blot assay, respectively. The level of interleukin-12 in cell supernatant was determined by ELISA. The SKOV3 cells were co-cultured with the supernatant of bone marrow mesenchymal stem cells transfected with (transfection group) or without (control group) interleukin-12 recombinant adenovirus vector. The proliferation of SKOV3 cells was determined by MTT assay. Flow cytometry was used to detect the cell cycle and apoptosis of SKOV3 cells. RESULTS AND CONCLUSION: RT-PCR and western blot results showed that interleukin-12 mRNA and protein were expressed in transfected bone marrow mesenchymal stem cells, but not found in empty vector group and blank control group. ELISA results showed that the content of interleukin-12 in the supernatant of bone marrow mesenchymal stem cells was (68.78±12.35) μg/L in the interleukin-12 transfection group after 48 hours culture, and no interleukin-12 expression was detected in the empty vector group and the blank control group, Interleukin-12-transfected bone marrow mesenchymal stem cells significantly inhibited the proliferation of SKOV3 cells, and the proliferation inhibition rate was increased with time (P < 0.05). The proportion of G1-phased SKOV3 cells was higher in the transfection group than in the control group (P < 0.05), and the percentage of G2-phased SKOV3 cells was lower in the transfection group than in the control group (P < 0.05). The apoptosis rate of SKOV3 cells in the transfection group was higher than that in the control group (P < 0.05). Our experimental findings indicate that bone marrow mesenchymal stem cells transfected with interleukin-12 recombinant adenovirus vector can express interleukin-12, inhibit the proliferation and induce apoptosis of ovarian cancer cells.

Objective To investigate the effects of different doses of dexmedetomidine on cerebral oxygen saturation and pulmonary shunt fraction in patients undergoing one-lung ventilation (OLV). Methods Sixty ASAⅠ-Ⅱpatients, aged 46-71 years, with body mass index (BMI)18-24 kg/m2 and scheduled for thoracotomy were randomly divided into three groups (n=20 each):high dose dexmedetomidine group (group D1), low dose dexmedetomidine group (group D2) and control group (group C). Dexmedetomidine 1μg/kg was infused in group D1 after anesthesia induction, and then a rate of 0.5μg·kg-1·h-1 was continuously infused. Dexmedetomidine 0.5μg/kg was infused in group D2 after anesthesia induction, and then a rate of 0.3μg · kg-1 · h-1 was continuously infused. Group C was received the equal volume of normal saline. Anesthesia was main?tained with propofol-remifentanil and intermittent iv boluses of rocuronium. Arterial and jugular venous blood samples were collected before anesthesia induction (T0), at 15 min after two-lung ventilation (T1), at 5 min (T2) and 30 min (T3) of OLV for blood gas analysis. Value of Qs/Qt was calculated and SctO2 was recorded at the same time. Results Compared with group C and group D2, Qs/Qt was decreased at T2 in group D1 (P<0.05). Qs/Qt was lower at T3 in group D1 and D2 than that of group C, and which was lower in group D1 than that of group D2 (P<0.05). In group C and group D1 a significant de?crease in SctO2 was observed at T2 and T3 compared to that at T0 and T1 (P<0.05). SctO2 was significantly higher at T2 and T3 in group D2 than that in group C and group D1 (P<0.05). Conclusion Dexmedetomidine given during OLV undergoing thoracotomy can improve oxygenation, decrease pulmonary shunt fraction and reduce the occurrence of low SctO2.
