Résumé
<p><b>OBJECTIVE</b>To explore the effects of aberrant expression of sperm protein 17 (Sp17) on the migration of the ovarian cancer cell line HO-8910.</p><p><b>METHODS</b>The recombinant plasmid pEGFP-Sp17 containing Sp17 and enhanced green fluorescent protein gene was transfected into the human ovarian cancer cell line HO-8910 with Lipofectamine 2000. The expression of Sp17 was examined by RT-PCR and Western blot, and the cell migratory capability detected by Transwell chamber assays.</p><p><b>RESULTS</b>Sp17 was expressed as a fusion protein with EGFP after transfected. There was a significant difference in the migratory cell number of the transfected and the control cells (156.6 +/- 14.9/HP vs 39.3 +/- 8.53/HP, P < 0.05).</p><p><b>CONCLUSION</b>The aberrant expression of Sp17 greatly enhances the migration of ovarian cancer cells.</p>

Objective To study the protective role of AngiotensinⅡreceptor inhibitor in ventilator-induced lung injury of rats.Method Forty healthy male SD rats were equally divided into four group (A,B,C,D group,n=10).Group A served as control group,group B had low tidal volume (V_T=10 ml/kg) with breathing rate (P)=80/min;group C had high tidal volume (V_T=40 ml/kg) group with breathing rate 80/min;group D had high tidal volume (V_T=40 ml/kg) group with breathing rate 80/min,all rats in group D were pretreated with Losartan.The duration of ventilation in 'all groups was two hours.Rats were sacrificed after experiment finished. The lung lavage liquid and lung tissue were collected and preserved with well established methods.Lung pathological change was observed by microscope;lung cell apoptosis was assessed with TUNEL;the expression of ANGⅡwas assayed with RT-PCR.The measured variables also included total protein,WBC,W/D,MPO. Results In comparison with B group,all variables in group C were significantly increased (P
