BACKGROUNDEmerging evidence suggests that stem cells can be used to improve cardiac function in patients after acute myocardial infarction. In this randomized trial, we aimed to use Doppler tissue tracking and strain imaging to assess left ventricular segmental function after intracoronary transfer of autologous bone-marrow stem cells (BMCs) for 6 months' follow up.

METHODSTwenty patients with acute myocardial infarction and anterior descending coronary artery occlusion proven by angiography were [corrected] randomized into intracoronary injection of bone-marrow cell (treated, n = 9) or diluted serum (control, n = 11) groups. GE vivid 7 and Q-analyze software were used to perform echocardiogram in both groups 1 week, 3 months and 6 months after treatment. Three apical views of tissue Doppler imaging were acquired to measure peak systolic displacement (Ds) and peak systolic strain (epsilonpeak) from 12 segments of LV walls. Left ventricular ejection fraction (LVEF), end-diastolic volume (EDV) and end-systolic volume (ESV) were obtained by Simposon's biplane method.

RESULTS(1) 3 months later, Ds and epsilonpeak over the infract-related region clearly increased in the BMCs group [Ds: (4.49 +/- 2.71) mm vs (7.56 +/- 2.95) mm, P < 0.01; epsilonpeak: (-13.40 +/- 6.00)% vs (-17.06 +/- 6.05)%, P < 0.01], but not in the control group [Ds: (4.74 +/- 2.67) mm vs (5.01 +/- 3.23) mm, P > 0.05; epsilonpeak: (-13.84 +/- 6.05)% vs (-15.04 +/- 6.75)%, P > 0.05]. At the same time, Ds over the normal region also increased, but the Ds enhancement was markedly higher in the BMCs group than that in the control group [(3.21 +/- 3.17) mm vs (0.76 +/- 1.94) mm, P < 0.01]. Parameters remained steady from the 3rd to 6th month in either group (P > 0.05). (2) LVEF in treated and control groups were almost the same at baseline (1st week after PCI) [(53.37 +/- 8.92)% vs (53.51 +/- 5.84)%, P > 0.05]. But 6 months later, LVEF in the BMCs group were clearly higher than that in the control group [(59.33 +/- 12.91)% vs (50.30 +/- 8.30)%, P < 0.05]. (3) There were no evident difference in EDV or ESV between two groups at baseline [EDV: (113.74 +/- 23.24) ml vs (129.94 +/- 32.72) ml, P > 0.05; ESV: (57.12 +/- 18.66) ml vs (62.09 +/- 17.68) ml, P > 0.05]. Three months later, EDV and ESV in the control group were markedly greater than those in the BMCs group [EDV: (154.89 +/- 46.34) ml vs (104.85 +/- 33.21) ml, P < 0.05; ESV: (82.91 +/- 35.79) ml vs (49.54 +/- 23.32) ml, P < 0.05]. But EDV and ESV did not change much from 3rd to 6th month in either group (P > 0.05).

CONCLUSIONSEmergency transplantation of autologous BMCs in patients with acute myocardial infarction helps to improve global and regional contractility and attenuate post-infarction left ventricular remodeling. Tissue tracking and strain imaging provide quick, simple and noninvasive methods for quantifying left ventricular segmental function in humans.

Objective To construct the small interfering RNA (siRNA) targeting heparanase gene and its expressing vector,and to observe its interference effect on the expression of heparanase gene and inhibitory effect on the invasive potential of human malignant melanoma A375 cells.Methods Three siRNAs were designed.The recombinant plasmid pRNATU6.1/heparanase-siRNA was designed and constructed. A375 cells were cultured,and transfected with pRNATU6.1/heparanase-siRNA.The cells treated with lipo- fectamine or Opti-MEM served as the controls.Real-time fluorescence quantitative PCR and Western blot were performed to evaluate the expression of heparanase RNA and protein in these treated A375 cells.The in vitro invasive potential of treated A375 cells was assessed by Matrigel gel assay.Results The siRNA targeting heparanase gene was successfully cloned to the eukaryotic expressing vector pRNATU6.1.The expression levels of both heparanase RNA and protein decreased significantly in siRNA-transfected A375 cells than those in the control cells.The in vitro invasive potential of siRNA-transfected cells was also signifi- cantly inhibited as compared with that of the control cells (P

OBJECTIVETo explore the application value of detection of Hepcidin together with indicator of iron overload on clinical diagnosis and treatment of MDS with iron overload by measuring Hepcidin and iron load indices of transfusion dependent myelodysplastic syndrome (MDS) patients.

METHODSEnzyme-linked immunosorbent assay (ELISA), radioimmunoassay and colorimetry were used to determine the Hepcidin, serum ferritin (SF) and serum iron (SI) levels of 106 serum samples from 68 cases of transfusion dependent MDS patients, 30 serum samples of MDS patients without transfusion and 60 serum samples of controls.

RESULTSFor MDS group, Hepcidin level in blood transfusion < 9 U subgroup was significantly higher than that in control group \[(583 ± 50) µg/L vs (175 ± 35) µg/L\] and there was a strong positive correlation between Hepcidin levels and SF (r = 0.976), but no correlation between Hepcidin and SI (r = 0.284); Both Hepcidin and SF level in transfusion 9 ∼ 24 U subgroup was significantly higher than those in control group \[(665 ± 80) µg/L vs (175 ± 35) µg/L; (1445 ± 275) µg/L vs (112 ± 26)µg/L\]; whereas for SI level, there was no difference between transfusion 9 ∼ 24 U subgroup and the control group. Hepcidin did not correlate with SF or SI; For blood transfusion > 24 U group, all of Hepcidin, SF and SI levels were higher than those in control groups \[(703 ± 64) µg/L vs (175 ± 35) µg/L; (2587 ± 352) µg/L vs (112 ± 26)µg/L; (20 ± 4) µg/L vs (14 ± 4) µmol/L\], Hepcidin negatively correlated with SF and SI (r = -0.536; r = -0.456). Hepcidin levels of RARS patients were significantly lower than RAEB patients \[(260 ± 40) µg/L vs (442 ± 51) µg/L\], and there was no significant difference between RARS group and control group regardless of the number of blood transfusion.

CONCLUSIONBoth Hepcidin and SF levels in MDS patients regardless of transfusion dependent or not, or the number of blood transfused were higher than those of normal controls, the increase of Hepcidin can not synchronize with the increase of SF level due to the increased blood transfusion, when blood transfusion > 24 U, Hepcidin level showed a negative relationship with SF and SI, reflecting the decreased ability of Hepcidin to inhibit body iron absorption during the increase of blood transfusion, which finally would lead to iron overload. We can predict the occurrence of iron overload in transfusion dependent MDS patients by dynamic monitoring concentration of Hepcidin.

The expression levels of programmed cell death 5 (PDCD5) are down-regulated in many malignancies. SG611-pdcd5, a recombinant conditionally replicative adenovirus carrying pdcd5 gene expression cassette, can evidently kill the leukemic cells and protect selectively the normal cells. The purpose of this study was to investigate the synergistic killing effect of SG611-pdcd5 and low-dose etoposide (VP-16) on K562 cells. K562 cells were treated with different concentrations of VP-16 or different multiplicities of infection (MOI) of SG611-pdcd5. After 48 hours of incubation the cell viability was determined by using MTT assay. The results showed that the cell viability of SG611-pdcd5 (MOI = 40) plus VP-16 (0.5 µg/ml) group significantly decreased as compared with single SG611-pdcd5 (MOI = 40) treatment group or single VP-16(0.5 µg/ml) treatment group (42.00 ± 5.75% vs 59.45 ± 4.12%; 42.00 ± 5.75% vs 82.91 ± 3.41%, respectively, both p < 0.05). The synergistic killing effect of SG611-pdcd5 plus VP-16 was higher than that of PDCD5 protein plus VP-16 or that of non-replicating adenovirus carrying pdcd5 (Ad-pdcd5) plus VP-16 (both p < 0.05). The cell viability of VP-16 (4.0 µg/ml) plus SG611-pdcd5 (MOI = 40) group, VP-16 (4.0 µg/ml) plus proPDCD5 (40 µg/ml) group and VP-16 (4.0 µg/ml) plus Ad-pdcd5 (MOI = 80) group was 37.09 ± 1.89%, 52.36 ± 1.64% and 73.64 ± 4.33%, respectively. It is concluded that SG611-pdcd5 can promote K562 cell death induced by low-dose VP-16. The combination of SG611-pdcd5 and VP-16 can enhance the killing effect on leukemic cells.
