Objective To investigate the treatment effectsand safety of ifosfamide,nedaplatin with pharmorubicin in relapsed ovarian carcinoma.Methods Sixteen relapsed ovarian carcinoma patients received nedaplatin 150mg in 0.9% sodium chloride 500ml dl,intravenously;pharmorubicin 40mg in 5% glucose 50 ml d1-2,intravenously;and ffosfamide 2.0g in 0.9% sodium chloride 500ml d1-5,intravenously.And the treatment effects and side effects were investigated.Results Of the sixteen patients,one had a complete response,six had a partial response,seven had stable disease,and two had progressive disease.The overall response rate was 43.75%(7/16).The major side effects were bone marrow suppression and gastrointestinal reaction.Conclusion Combination of ffosfamide,nedaplatin and pharmorubicin were very effective in relapsed ovarian carcinoma and the side effects were tolerable.Therefore the regimen is worth promoting in the clinical application.

In this study, the mature peptide sequence of a pectin lyase gene A was amplified from Aspergillus niger strain EIM-6 by using RT-PCR reverse transcription technique. The cloned gene was then inserted into a Pichia pastoris expression vector pPIC9k to produce the recombinant expression plasmid pPIC9K-pelA. By using electric shocks, we successfully transformed the recombinant pPIC9K-pelA into Pichia pastoris GS115. The activity of the engineered strain reached to 2.3 U/mL after induction with the final concentration of 1.5% methanol. SDS-PAGE analysis revealed that the pPIC9K-pelA transformant had an additional protein band of approximately 38 kD, which was not present in the control. There were no significant differences between the recombinant and native pectin lyase with regard to their hydrolysis activities.
