Objective To compare in vitro fertilization and embryo transfer( IVF-ET ) outcome of gonadotropin-releasing hormone( GnRH ) antagonist protocol and GnRH agonist long protocol in patients with polycystic ovary syndrome ( PCOS)and to provide reference for rational selection of ovulation stimulation protocol for PCOS patients. Methods One hundred and four patients with PCOS who underwent IVF-ET were randomly divided into two groups. In the study group,41 patients were subjected to the GnRH antagonist protocol;In the control group,63 patients were subjected to a long protocol of GnRH agonist. Doses and duration of gonadotropin therapy,the thickness of endometrium and the profile of hormone level on the day of HCG administration,the number of retrieved oocytes,the ratio of fertilization,the ratio of cleavage,the ratio of the good quantity embryos,implantation rate of embryo,pregnancy rate,the cycle cancellation rate and the incidence rate of ovarian hyperstimulation syndrome( OHSS)were recorded. Results The IVF-ET outcome of the two groups was similar with respects to the number of oocytes,the ratio of fertilization,the ratio of cleavage,implantation rate of embryo and the pregnancy rate( P﹥0. 05). Significant differences were found(P﹤0. 05)between the two groups regarding to the doses and duration of gonadotropin therapy,the levels of serum E2 and LH on the day of HCG administration,and the cycle cancellation rate. The incidence rate of OHSS was not significantly different ( 2. 44% vs. 12. 70%) between the two groups. Conclusion The duration of gonadotropins administration,the cycle cancellation rate,incidence of OHSS and the financial burdern are reduced in patients treated with GnRH antagonist. The growth of follicle,the ratio of fertilization,the ratio of cleavage,implantation rate of embryo and the pregnancy rate are not different between the two methods. The GnRH antagonist protocol is optimal for patients with PCOS.

Objective To explore the toxicity and safety of 32P-CP-PLLA seeds interstitial implantation. Methods 30 beagle dogs were randomly divided into 10 groups according to different drugs (32P-CP-PLLA and 32P-CP),different doses (185, 370 and 740 MBq) and different sites (gluteus and liver). At different time-points after surgery, the weights of dogs were measured. The blood routine and blood biochemical indexes,PC Ⅲ ,HA,CG,PCⅣ and LN were examined. ECT imaging was performed and histology was observed dynamically. Blood, urine and faeces were measured continuously for 12 weeks and 30 days, respectively. Results ECT imaging demonstrated in seed groups and 32P-CP muscle groups radioactivity concentrated continuously in the area of implantation, without liver imaging. 471.67 MBq/m2 of 32 P-CP was injected in liver,while the absorbed dose was 31 Gy,without significant liver damage. When the dose was 794. 28 MBq/m2 , the absorbed dose was 56 Gy,with strong liver and systemic toxicity. But implanting seeds at the same or higher dose, the absorbed dose was 89.83-178.68 Gy in the area of implantation, and the rest liver was 1.09-2. 18 Gy,without liver damage. Dogs in liver group died at 23, 29 and 45 d, respectively, and the inspections of liver fibrosis were higher than the means of the other groups.Blood routine and blood biochemistry indexes between the other groups showed no significant differences.Effective half-life of 32P-CP-PLLA was 11.78 d, while that of 32P-CP was 6. 82 d in liver, and 8. 73 d in gluteus. Mild to moderate injury were found in liver group at 4 weeks. Moderate to serious injury were found. Liver cell necrosis and proliferation were found at 4-6 weeks in other liver groups. In muscle groups,only cellular edema was found in muscle groups at 2 week. The radioactivity count rate in blood for seed groups showed slowly jagged decreasing over time, and decreased exponentially for 32PCP groups. The radioactivity count rate in urine and faeces were multi-peak descending in seed groups. Conclusions 32P-CP-PLLA seeds have the advantages of suitable target location, degradable, non-migration and easy to protection, and it could be used in treatment for different blood supply types of solid tumors. Liver of beagle dog could endure the dose from 32 P-CP-PLLA seed twice as 32P-CP lethal dose.
