Objective To analyse the effects of serum estradiol levels during controlled ovarian hyperstimulation (COH) on the outcomes of in vitro fertilization and embryo transfer (IVF-ET). Methods The clinical data of 472 patients undergoing IVF-ET with GnRH analogues recombinant FSH long protocol were retrospectively analysed. The area under the curve (AUC) of estradiol (E2) level was calculated during COH, and patients were categorized into groups according to the percentile of AUC of E2(AUCE2) during COH. The general characteristics and parameters related to the outcomes of IVF-ET were compared among groups. Results The 10th percentile and 90th percentile of AUCE2 were 3 347.0 pmoL/L and 14 414.3 pmol/L, respectively. Four hundred and seventy-two patients were divided into lower reaction group (AUCE2 3 347.0 pmol/L, n=48), normal reaction group (14 414.3 pmol/L>AUCE2 > 3 347.0 pmol/L, n=376) and higher reaction group (AUCE2≥14 413.3 pmol/L, n=48). There was no significant difference in age, body mass index, baseline follicle stimulating hormone level, time of treatment with gonadotropin, endometrium thickness on day of transfer and embryos transferred(P>0.05). Compared with lower reaction group and normal reaction group, the number of oocytes per retrieval and number of embryos frozen were significantly larger(P<0.01) and the mild/severe ovarian hyperstimulation syndrome rate was significantly higher in higher reaction group(P<0.05). There was no significant difference in fertilization rate, cumulative embryo score, high-grade embryo rate, clinical pregnancy rate and implantation rate among groups (P> 0.05). Conclusion Sustained snpraphysiological serum E2 levels during the COH process do not adversely affect the quality of oocytes and embryos, clinical pregnancy rate and implantation rate to some extent in IVF-ET.

Objective To evaluate the significance of human interleukin-31(IL-31)in the pathogenesis of atopic dermatitis and its correlation with pruritus in patients with atopic dermatitis(AD).Methods Twenty-two children with mild to severe atopic dermatitis and 22 age-matched healthy controls were included in this study.Patients and controls were randomly and equally assigned into stimulation and non-stimulation groups.Venous blood samples were obtained from all participants,peripheral blood mononuclear cells were isolated from these samples and cultured with(stimulation groups)or without(non-stimulation groups)staphylococcal enterotoxin B(SEB)for 24 hours.Then,the mRNA expression of IL-31 on PBMCs was assessed via real-time reverse transcription-PCR.ELISA was used to detect the total serum IgE level in these objects.The severity of AD in patients was rated according to scoring atopic dermatitis(SCORAD).The relationship between the mRNA expression of IL-31 and the level of serum total IgE.severity of atopic dermatitis,and degree of pruritus.was evaluated.Results The expression of IL-31 mRNA on non-stimulated PBMCs from patients was 23.2 folds as high as that from the healthy controls(P＜0.01).The stimulation with SEB upregulated the mRNA expression of IL-31 on PBMCs.and the increase on PBMCs from patients was 20.44 times of that from the controls.The total serum IgE level was 260.05 IU/mL(5.9-1131.01 IU/mL)and 17.7 IU/mL(5-140.7 IU/mL)in the Patients and controls respectively(P＜0.01).There was no significant correlation between the mRNA expression of IL-31 and disease severity or total serum IgE level(r=0.07.0.22respectively.both P＞0.05)in patients witll AD.Condusions IL.3 1 is involved in t11e pathogenesis of AD,which is unlikely to be IgE-dependent.SEB can induce the rapid expression of IL-31 on PBMCs of healthy human,and is an important modulator for the production of IL-31.
