Objective To screen the target genes that contribute to cisplatin resistance in ovarian cancer treatment. Methods Gene expression and methylation profiles of ovarian cancer cells that were sensitive or resistant to cisplatin with accession number GSE15709 were downloaded from GEO database. Differential expressed and methylated genes were identi?fied through associating packages in R. DAVID database to screen the enriched GO terms and pathways of the different ex?pressed genes between A2780 and A2780/DDP. Gene Set Enrichment Analysis (GSEA) of different gene was performed against DAVID database. Genes that exhibited difference in both expression and methylation profiles between the two types of ovarian cancer cells as well as genes that present contradictory profile between expression and methylation were verified via qRT-PCR. Results We found 416 different expressed genes and 281 methylated genes between the two types of ovari?an cancer cells respectively. These differential genes were rich in pathways of cell cycle, DNA replication, nucleus division , p53 signaling , and negative regulation of protein modification process etc. Four genes demonstrated contradictory profile be?tween expression and methylation in the two types of ovarian cancer cells and were verified by qRT-PCR. Conclusion Combination of bioinformatics and molecular biology is useful in the identification of target genes that contribute to resis?tance of cisplatin in ovarian cancer treatment and further reveal molecular mechanism behind it.

Objective To evaluate the efficacy of manually controlled jet ventilation with Manujet Ⅲ apparatus (VBM Co, Germany) for removal of airway foreign body in children. Methods One hundred and twenty ASA Ⅰ or Ⅱ children aged 10 months-12 yr, weighing 8-35 kg undergoing removal of airway foreign body were randomly divided into 3 groups (n=40 each) : group Ⅰ spontaneous respiration (SR) ; group Ⅱ intermittentpositive pressure ventilation through the short side tube of the rigid bronchoscope (IPPV) and group Ⅲ manually controlled jet ventilation with Manujet Ⅲ (JV). Anesthesia was induced with methylprednisolone 2 mg/kg, propofol 2 mg/kg and γ-OH 70 mg/kg in group SR (Ⅰ) and with methylprednisolone 2 mg/kg, propofol 4-5 mg/kg, fentanyl 1.5 μg/kg and succinylcholine 2 mg/kg in group IPPV and JV (Ⅱ,Ⅲ). The bronchescope insertion condition, the occurrence of hypoxia during and after operation, body movement during operation, the rate of successful removal of the foreign body, the duration of operation, anesthesia emergence time and perioperative side effects were recorded. Resulls The rate of good bronchescope insertion condition and successful removal of airway foreign body were significantly higher, the rate of hypoxia during and after operation, body movement, breath holding and restlessness were significantly lower and duration of operation and anesthesia emergence time were significantly shorter in group IPPV and JV than in group SR (P<0.05). The rate of intraoperative hypoxia was significantly lower in group JV than in group IPPV (P<0.05). Conclusion Jet ventilation with Manujet Ⅲ can reduce the occurrence of hypoxia during removal of airway foreign body in children and does not interfere with the operation.
