Objective To evaluate effects of different laparoscopic procedures for hydrosalpinx on ovarian responses to superovulation induction during in vitro fertilization-embryo transfer(IVF-ET).Methods A total of 65 patients with infertility derived from hydrosalpinx underwent 67 cycles of IVF-ET from January 2002 to January 2005.Before the IVF-ET,the patients were given bilateral laparosocpic salpingectomy(Group A,n=47,48 cycles) or laparosocpic proximal tubal ligation and distal tubal salpingostomy(Group B,n=18,19 cycles).Another 58 patients with proximal tubal occlusion without hydrosalpinx were simultaneously included for 58 cycles of IVF-ET(Group C).Results The fertilization rates,cleavage rates,implantation rates,and clinical pregnancy rates were 85%?21%,95%?17%,49%(55/113),and 79%(38/48) in the Group A,83%?17%,98%?7%,47%(21/45),and 68%(13/19) in the Group B,and 81%?22%,92%?16%,41%(57/140),and 66%(38/58) in the Group C,respectively,without statistically significant difference among the 3 groups(F=0.48,P=0.620;F=1.22,(P=0.297);?~2=1.691,P=0.429;?~2=2.471,P=0.291).The doses of gonadotrophin,the duration of stimulation,and the number of retrieved oocytes were 29.4?10.3 vials,9.4?1.7 d,and 11.4?5.6 in the Group A,24.7?7.7 vials,9.0?1.8 d,and 12.8?6.1 in the Group B,and 28.4?8.8 vials,9.1?1.8 d,and 11.4?5.3 in the Group C,respectively,without statistically significant difference among the 3 groups(F=1.77,P=0.174;F=0.52,P=0.593;F=0.51,P=0.599).Conclusions Laparosocpic salpingectomy or laparosocpic proximal tubal ligation with distal tubal salpingostomy for hydrosalpinx does not impair ovarian responses to the superovulation induction.Both of the procedures may be considered for the treatment of hydrosalpinx prior to IVF-ET.

Nanobody is a kind of antibody from camel, which misses light chain. Nanobody has the same antigen binding specificity and affinity as mAb. Moreover, because of its small molecular weight, high stability and easy preparation, nanobody has great value of biomedical applications. In this study, we successfully prepared highly pure antiEGFR nanobody in E.coli using genetic engineering techniques. Cell proliferation assay (CCK-8 assay) and migration experiments (cell scratch test and Transwell assay) indicated that the recombinant antiEGFRnano can significantly inhibit the proliferation and migration of endometrial cancer cells. These results provide a new way of thinking and methods for EGFR-targeted therapy of endometrial cancer.

Objective To investigate the effect of different amplification methods and probes with various length on the results of comparative genomic hybridization (CGH) analysis of pre-implanted single blastomere and to establish the basis for preimplantation genetic diagnosis.Methods Twenty blastomeres of embryo at 6-8 cells stage were randomly divided into A and B group with 10 in each.Twenty peripheral blood lymphocytes from a healthy man were similarly divided into C and D group with 10 in each.Degenerate oligonucleotide primed polymerase chain reaction (DOP-PCR) was used to amplify whole genomic DNA in group A and C,and multiple displacement amplification (MDA) was used in group B and D for whole genome amplification (WGA).The specificity of resultant products was confirmed by amplification of TBX1 gene exon 2.CGH was performed respectively with 250-750 bp and 750-2000 bp probes prepared from the amplified whole genomic DNA.The result of CGH was verified by sex-determining region of Y (SRY).Results (1) Nine of the 10 samples in group A and all in group C were amplifiable by DOP-PCR,but there were multiple non-specific bands in the amplification of TBX1 exon 2 when WGA products were used as templates.When 250~750 bp probe was used in CGH,1 of the 5 blastomeres was failed and another one had different karyotype from that analyzed by SRY.(2) All samples in group B and D were successfully amplified by MDA,and the non-specific bands were significantly less in the amplification of TBX1 exon 2.All 5 blastomeres were successful in CGH with the 250~750 bp probe.Moreover,the karyotype was in agreement with that of SRY.(3) When 750 ~ 2000 bp probe was used,the CGH results were suboptimal.Conclusions In WGA of single blastomere,MDA is superior to DOP-PCR in the stability and specificity.The karyotype image detected by CGH with the 250~750 bp probe is clear and homogenous.

OBJECTIVETo investigate the main correlative factors affecting the pregnancy rate of intrauterine insemination (IUI) by means of analyzing 186 patients and 216 cycles of IUI.
METHODSComparisons were made between different pregnancy rates from five respects: infertility reasons, stimulation and natural cycles, different protocols for stimulating ovulation (CC group, CC + hMG group, hMG group), two methods for semen treatment (swim-up and gradient centrifugal), and insemination time (endometrial thickness and E2 levels at the day of hCG injection, and times of IUI).
RESULTSThe pregnancy rates resulting from male and cervix factors (29.82%, 25.00%) were significantly higher than those from other factors. There were few statistical differences in the pregnancy rates between stimulation and natural cycles (19.54% vs 16.67%), between the three different protocols for stimulating ovulation (CC 6.50%, CC + hMG 14.28%, hMG 22.30%), between gradient centrifugal and swim-up methods (20.13% vs 16.13%) and between one-time IUI and two-time IUI (19.73% vs 17.39%) (P > 0.05). However, the pregnancy rates were statistically correlated with the endometrial thickness at the day of hCG injection and different E2 levels of the follicles over 14 mm in diameter (P < 0.05).
CONCLUSIONIUI is of more applied value for infertility caused by male and cervix factors. With these factors in view, to choose the most suitable insemination time is the key to increasing pregnancy rate.

OBJECTIVETo evaluate the impact of the concentration of circulating luteinizing hormone (LH) in the late-follicle phase on the outcome of in vitro fertilization for normogonadotrophic women.
METHODSIntracytoplasmic sperm injection treatment was conducted in 432 consecutive cycles of normogonadotrophic women. A stimulation protocol with mid-luteal gonadotropin-releasing hormone (GnRH) agonist down-regulation and ovarian stimulation with follicle stimulating hormone (FSH) was used in all cycles. hMG was added when a follicle of > or = 14 mm was present (FSH + hMG group), not in the control group (FSH-alone). LH and oestradiol concentration in the serum on hCG day were detected. Based on LH levels, patients in the FSH + hMG group were again divided into four subgroups: LH < or = 1, 1 < LH < or = 2, 2 < LH < or = 3, and 3 < LH < or = 10 IU/L.
RESULTSOestradiol concentration on the day of hCG injection in the FSH + hMG group was higher than that in the FSH-alone group [(3435.51 +/- 2029.01) pg/ml vs (2620.62 +/- 1604.80) pg/ml, P < 0.05]. More embryos were transferred in the FSH-alone group than in the FSH + hMG group [(2.77 +/- 0.45) vs (2.22 +/- 0.46), P <0.001]. Fertilization rate, implantation rate, and clinical pregnancy rate were similar between the FSH-alone group and the FSH + hMG group (77.52% vs 78.31%, 41.42% vs 41.68%, 64.56% vs 62.64%, P > 0.05), as well as among the four subgroups of the FSH + hMG group (P > 0.05).
CONCLUSIONThe adding of suitable amount of hMG and physiologically limited LH concentration in the late-follicle phase have no negative effect on the outcome of in vitro fertilization/intracytoplasmic sperm injection for normogonadotrophic women.
