Objective: To assess the safety and efficacy of the standard manual compression and 2 arterial puncture closing devices, Angioseal and Perclose, for hemostasis at the femoral artery access site in patients undergoing coronary angiography (CAG) or percutaneous coronary interventions (PCI). Methods: Totally 366 patients undergoing coronary angiography or PCI were assigned to receive either Angioseal (n=128), Perclose (n=110) or standard manual compression (n=128). The efficacy endpoint (immediate hemostasis, successful hemostasis rate, operating time, time of leg immobilization and time to hemostasis) and safety endpoint (vasovagal reflex, major complications, local complications, hematocrit drop, etc.) were evaluated. Risk factors (gender, age, body mass index, comorbid conditions, antiplatelet agents, and anticoagulant agents, etc.) were also analyzed. Results: The successful hemostasis rates were similar be tween Angioseal group and Perclose group, but the rate of immediate hemostasis of Angioseal group was higher than that of Perclose group (P<0.01). Time of leg immobilization and time to hemostasis in Angioseal group and Perclose group was shorter than those of manual compression group(P<0.01). Both vasovagal reflex (9.3%) and major complications (3.1%) were only noticed in manual compression group. The rates of local complications in manual compression group and Angioseal group were both lower than that of Perclose group(P<0.01). Post-procedure unfractionated heparin was associated with increased risk of hematoma (OR=4.382, P<0.05), post-procedure clopidogrel (OR=3.549, P<0.01) and interventional procedures (OR=6.584, P<0.05) were associated with increased risk of blood oozing, and female gender was associated with a reduced risk of blood oozing (OR=0.132, P<0.05). The successful hemostasis rates were lower in the elderly and those receiving PCI. Post-procedure unfractionated heparin and low molecular weight heparin was associated with longer hemostasis time. Conclusion: Perclose and An gioseal can be an alternative of standard manual compression for hemostasis of the femoral artery access site. Angioseal may be better than Perclose regarding the immediate hemostasis and local complications.

Objective:To study the HLA-DPB1 allele polymorphism in Ewenki from Inner Mongolian.Methods:HLA-DPB1 allele polymorphism in normal Ewenki were determined by PCR with sequencing-based-typing(SBT).Results:20 HLA-DPB1 alleles were observed and compared with other ethnic groups,the allele frequency of HLA-DPB1*02012(24.4%) and DPB1*0402(22.6%),DPB1*0401(20.2%),DPB1*0501(10.7%) are highest,while others are lower.Conclusion:The distributions of HLA-DPB1 alleles frequencies in normal Ewenki from Inner Mongolia has a unique style.It is most important to further study anthropology and related to illness in Ewenki nationality.

Endotoxins are lipopolysaccharides ( LPS) , major component of out wall in Gram-negative bacteria. Often they are considered as "prime criminals" of triggering systemic inflaming reaction such as sepsis, bacteremia and so on. It was found in recent years that bactericidal/permeability-increasing protein, a 55kDa member of lipid-related protein family, was a kind of natural molecule of anti-infection and it has special endotoxin-neutralising activity and antibacterial activity. Comprehensive phase II/III clinical trials demonstrated the feasibility and safety of recombinant BPI. So pharmaceutical corporations are attracted to try to apply it to therapy.

2 cm) who were treated with endoscopic polypectomy in 2 different means,respectively.Methods The clinic data of 68 children with giant colonic polyps were review analyzed.Thirty-five cases were received endoscopic clips ligation and the other 33 cases were received endoscopic snare resection.Results All the 35 cases out of endoscopic clip ligtion group were sucessfully cured.There were only 3 cases showedl a little bleeding in this group.In the endoscopic snare resection group,there were 10 cases showed bleeding,8 cases showed polypectomy syndrome,1 case transferred into(operation).Conclusions The complication incidence in endoscopic clips ligation group is lower than that in endoscopic snare resection group.The endoscopic clipping brings about an effective and safe way to treat giant colonic polyps in children.

The gene which encodes (R)-specific carbonyl reductase(rCR) from Candida parapsilosis CCTCC M203011 was cloned.The cloned sequence includes an open reading frame (ORF) consisting of 1011bp, encoding a protein of 336 amino acids, with a molecular weight of 35.9 kD.The nucleotide sequence showed 99% similarity to those of the other members of the alcohol dehydrogenase superfamily.A recombinant Escherichia coli JM109 strain harboring the expression plasmid, produced (R)-1-phenyl-1,2-ethanediol(100%e.e,80.4%yield) from ?-hydroxyacetophenone without any additive to regenerate NAD~ + from NADH.

OBJECTIVETo study the protective effect of hyperoxia solution on acute lung injury caused by phosgene poisoning by observing the changes of PaO2 and malondialdehyde (MDA) contents, superoxide dismutase (SOD) activity in serum and Glutathione (GSH/GSSG) contents in lung tissues.

METHODSThe rabbits were divided into normal control group, hyperoxia solution (H0) and balance salt (BS) groups. Group HO and Group BS inhaled phosgene and the former was given intravenously hyperoxia solution (which was replaced by balance salt solution in Group BS). The content of MDA and the activity of SOD in serum were observed at different time points, the amount of GSH and GSSG in lung tissue were also measured.

RESULTS(1) The serum MDA contents increased and PaO2, SOD activity decreased significantly in Group HO and Group BS along with time increasing as compared with control group. The contents of GSH in lung tissue decreased in two groups compared with that in control group, however the contents of GSSG ascended instead. (2) At 3 and 8 h of the experiment, PaO2 of Group HO [(9.91 +/- 0.49), (9.15 +/- 0.46) mm Hg respectively] were significantly higher than those of Group BS [(9.03 +/- 0.76), (8.11 +/- 0.57) mm Hg respectively] (P < 0.01). The contents of MDA of Group HO (3.66 +/- 0.35), (5.31 +/- 0.15) micromol/L respectively] were lower than those of Group BS [(4.32 +/- 0.26), (7.4 +/- 0.33) micromol/L respectively] (P < 0.01). SOD activity in Group HO [(237.37 +/- 29.96), (208.10 +/- 18.80) NU/ml respectively] were higher than those of Group BS [(195.02 +/- 21.44), (144.87 +/- 21.26) NU/ml respectively] (P < 0.05 or P < 0.01). The content of GSSG lung tissue in Group HO (423.67 +/- 38.21) micromol/L were lower than those of Group BS (523.85 +/- 43.14) mol/L (P < 0.01). There were no significant differences in the content of GSH in lung tissues between Group HO and group BS.

CONCLUSIONHyperoxia solution can reduce acute lung injury of rabbits following phosgene poisoning.
