Résumé

<p><b>OBJECTIVE</b>To investigate the influential factors for the prognosis in patients with paraquat poisoning.</p><p><b>METHODS</b>Retrospective analysis was performed on 40 patients with acute paraquat poisoning to evaluate serum urea nitrogen, creatinine, alanine aminotransferase, and aspartate aminotransferase levels and organ injuries.</p><p><b>RESULTS</b>Among the patients, 21 had lung injury, 26 had kidney injury, 13 had multiple organ dysfunction syndrome, and 12 died. The factors associated with lung injury were kidney injury and serum urea nitrogen and creatinine levels within 24 hours after paraquat poisoning.</p><p><b>CONCLUSION</b>The renal function in early stage of paraquat poisoning is related to lung injury and thus can be used asa predictor for the incidence of lung injury.</p>

Résumé

<p><b>OBJECTIVE</b>To construct cyclin D2 (CCND2) short hairpin RNA ( shRNA) plasmid for repressing the expression of CCND2 in human myeloma cell line LP-1,and to detect its effect on the proliferation and apoptosis of LP-1 cell.</p><p><b>METHODS</b>A CCND2 shRNA model was constructed and cloned into plasmid pGensil-2, then the plasmid was transfected into LP-1 cell in vitro. The CCND2 expression cell proliferation, cell cycle and cell apoptosis of the transfected LP-1 cells were studied by RT-PCR, trypanosome staining, flow cytometry and annexin V assay.</p><p><b>RESULTS</b>The transfection efficiency of LP-1 cell was 34. 2%. In the transfected LP-1 cell CCND2 mRNA expression was reduced significantly, the cell growth was inhibited significantly and the cell cycle was partly arrested in G, phase. The apoptosis rate of the transfected LP-1 cell after 72 h was (25.7+/-4.8)%.</p><p><b>CONCLUSION</b>The inhibition of CCND2 in LP-1 cells could inhibit the cell growth and induce cell apoptosis. CCND2 maybe a new therapeutic target.</p>
