    Objective To compare the anti-radiation effect between pterostilibene and resveratrol in equimolar oral doses on ICR mice. Methods ICR mice of 6–8 weeks were selected to receive whole body irradiation of 6.5 Gy γ-ray.The mice were randomly divided into six groups to receive the following treatment:Control group, 0.05% CMC-Na; positive control group, rubidate 100 mg.kg-1 ; low- and highdose resveratrol groups, resveratrol at 50 or 150 mg.kg-1 ; low- and high-dose pterostilibene groups, pterostilibene at 56 or 168 mg.kg-1.The mice of the above groups were administered intragastrically 3 days, 2 days, and 1 day before the radiation.After the radiation, the mice were administered intragastrically for 5 consecutives days.The thymus, liver, spleen, lung and bilateral femurs were weighed to calculate corresponding organ indexes.White blood cell count (WBC), blood platelet (PLT), bone marrow nucleated cells (BMNC) and bone marrow DNA were determined, so as to evaluate the radiationprotective effect of pterostilibene and resveratrol. Results Compared with control mice, the indicators of all experiment groups were increased and most have significant difference (P<0.05); the antiradiation effect of pterostilibene was better than resveratrol at the same equimolar oral dose, with significant difference between the lowdose pterostilibene (56 mg.kg-1 ) group and the lowdose resveratrol (50 mg.kg-1 ) group. Conclusion Pterostilibene has better antiradiation effect on ICR mice than resveratrol, and the antiradiation effect of pterostilibene at 56 mg.kg-1 is the best.

    Objective To investigate the effect and possible mechanism of tetramethylpyrazine involved in regulating vascular calcification. Methods Angiosteosis in rats was induced by vitamin D3 intramuscular injection and nicotine intragastric administration.Calcification of vascular smooth muscle cells (VSMC) was induced by β-glycerophosphate.The Ca2+ contents in aorta and VSMCs were measured by an atom absorptive spectrophotography.Ca2+ deposition in aorta and VSMCs was evaluated by the 45CaCl2 absorption and Von Kossa staining.The alkaline phosphatase (ALP) activity was detected by a chemical colorimetric method.The mRNA level of osteopontin (OPN) was determined by reverse transcription PCR. Results ALT activity, Ca2+ contents and 45Ca2+ deposition were significantly increased, but osteopontin mRNA expression was significantly decreased in calcified vessel and VSMC.After treatment with tetramethylpyrazine (40 mg.kg-1 in vivo and 200 mg.L-1 in vitro), the Ca2+ content, 45Ca2+deposition and ALP activity were decreased, while osteopontin mRNA expression was increased in plasma, aorta and VSMCs, respectively. Conclusion Our Results indicated that tetramethylpyrazine significantly protects the aorta against calcification partly through the activation of the endogenous anticalcification system in local aorta tissues.

    Objective To investigate the influence of c-Myc on hypoxiainducible factor 1, α subunit (HIF-1α) and proliferationof HT-29 cells. Methods The plasmid pcDNA3.1-c-Myc was constructed and transfected into human colon carcinoma cell line HT-29.Efficiency of transfection was detected by Western blotting.The mRNA and protein levels of HIF-1α in normoxia and hypoxia were measured by realtime PCR and Western blotting.The mRNA levels of vascular endothelial growth factor (VEGF) and eNOS (the target genes of HIF-1α) were measured by realtime PCR.PcDNA3.1-c-Myc plasmid and HIF-1α siRNA were cotransfected into HT-29 cells.MTT was used to detect the proliferation of the HT-29 cells. Results The plasmid pcDNA3.1-c-Myc was successfully constructed.After transfection into HT-29 cells in normoxia and hypoxia, realtime PCR showed that the mRNA level of HIF-1α had no change, while Western blotting showed the protein level of HIF-1α was significantly increased.The mRNA levels of VEGF and eNOS were significantly increased.The proliferation of HT-29 cells was stimulated through the overexpression of c-Myc.But cotransfection of pcDNA3.1-c-Myc plasmid and HIF-1α siRNA decreased cell proliferation in HT-29 cell line. Conclusion c-Myc regulates the proliferation of HT-29 cells through HIF-1α.

    Objective To investigate the effect of dexmedetomidine on perioperative pulmonary shunt fraction for patients with esophageal cancer. Methods Sixty patients, ASAⅠ or Ⅱ, scheduled for esophagectomy under general anesthesia were randomly assigned into three groups (20 patients in each group) to intravenously receive treatment of high-dose dexmedetomidine (HDex), low-dose dexmedetomidine (LDex) or normal saline.Patients in group HDex and group LDex respectively were administered intravenously at a loading dose of 0.6 μg.kg-1 and 0.3 μg.kg-1 dexmedetomidine over 10 min, respectively.Both group HDex and group LDex were treated with a maintenance dose of 0.3 μg.kg-1.h-1 over half an hour.Patients in placebo group received normal saline.After anesthesia, at 15 min after twolung ventilation (TLV1), 15 min and 1 h after onelung ventilation (OLV1 and OLV2), 15 min after restoration of two lung ventilation (TLV2), 1 and 6 h post operation (P1 and P6), blood from internal jugular vein and radial artery was collected for blood gas analysis.The intrapulmonary shunt (Qs/Qt) was calculated. Results At OLV1 and OLV2, pulmonary shunt fraction in the blank group was significantly different from those of the highdose group and the lowdose group (OLV1:LSD-t respectively equals -3.03 and -3.39, P<0.05; OLV2:LSD-t respectively equals -2.91 and -2.65, P<0.05), but the values between the high-dose group and low-dose group were not significantly different (P>0.05). Conclusion Dexmedetomidine exerts a greater impact on the pulmonary shunt fraction over time of onelung ventilation, however, during twolung ventilation and 6 h post operation, the impact is not significant.
