Objective To compare the binding characteristics of insulin receptors (IR) on ovary,adrenal and hepatic plasma membrane from rats. Methods The number and affinity of IR was detected by radioligand binding assay. Results Scatchard plot analyses showed that the receptor numbers for high affinity sites are 7. 359?10/mg protein, 8. 029? 10/mg protein and 6. 440?10/mg protein of liver,ovarian and adrenal plasma membrane with KD of 6.147?107 M-1, 1. 528?10, M-1, and 1. 010?107 M-1 that. The receptor numbers for low affinity sites are 2. 403?10/mg protein,2. 212?10/mg protein,and 2. 257?10/mg protein respectively with KD of 2. 920?10M-1,2. 008?10 M-1 and 0. 433?10sM-1. Conclusion There are abundent IR on ovary and adrenal just as many as those on liver, although the KD are smaller. It suggests that insulin may play an important regulatory role in ovary and adrenal.

Objective To investigate the high risk factors, clinical manifestation and therapy strategy of ovarian hyperstimulation syndrome (OHSS) in assisted reproduction techniques (ART). Methods Clinical data of 136 cycles of OHSS patients after in vitro fertilization-embryo transfer (IVF-ET) from 2005 to 2008 were analyzed retrospectively. Results (1) A large number of follicles stimulated, luteal phase supported with hCG and pregnancy were high risk factors to induce OHSS. (2)Most of OHSS occurred on the 3~(rd) day to 10~(th) day after administration of medicine to induce ovulation. (3) Longer disease process, more severe symptoms and larger amount albumin used for treatment of OHSS were commonly observed in pregnant patients with OHSS compared with non-pregnant ones. (4) Human serum albumin through intravenous dripping was one of the most successful treatment as plasma expanders through restoration of effective blood volume; paracentesis was necessary for critical OHSS patients with severe ascites and hydrothorax. Conclusions OHSS is a serious complication of controlled ovarian hyperstimulation, which deserves proper prevention and treatment.

Polycystic ovary syndrome (PCOS) is a complex hormonal disorder and one of the most common reproductive endocrinology abnormalities in women. Recently, many studies have been conducted assessing Chinese herbal medicine as an alternative treatment for women with PCOS, it is, therefore, worthwhile to analyze and observe the curative effects of traditional Chinese medicine treatment in PCOS.

Objective:To investigate the rescue role of Bu-Shen-Yi-Qi Formula on the apoptosis of first trimester trophoblasts induced by TNF-?/IFN-?.Methods:Cell viability was measured by MTT assay,and cell numbers in sub-G1 phase were determined by FCM.The amount of apoptotic cells was evaluated by TUNEL,caspase-3 enzyme activity was examined by caspase-3 active assay kit.Bcl-2 and XIAP protein expression were detected by Western blot.Results:(1)Cell viability decreased,but apoptotic cells increased and the cells in sub-G1 phase accumulated when cultured with TNF-? and IFN-? for a 24 h and the reaction became more serious following a 48 h culture.However,cells cocultured with drug-containg serum showed enhanced cell viability,less apoptotic cells and low enzyme activity.Also,cells in sub-G1 phase decreased and Bcl-2,XIAP protein expression were enhanced when the drug-containg serum were added.This change showed time and dosage dependent.Cell viability cultured with blank serum had no significant changes.Conclusion:Bu-Shen-Yi-Qi Formula rescue trophoblasts apoptosis induced by TNF-? and IFN-?.

Objective:To explore whether the Formula of Tonifying Kidney of Vital Essence can modulate secretion of IL-4 and IFN-? by the CD4+T cells from human decidua during first trimester,which will lead to further investigate the anti-abortional effect mechanisms of the Formula of Tonifying Kidney of Vital Essence.Methods:40 female adult SD rats were divided randomly into two groups:one group was gavaged with the Formula of Tonifying Kidney of Vital Essence;another was gavaged with normal saline,twice a day for 3 days.The two groups of rats were gavaged with the same volume of the decoction or saline.Thereafter the blood was collected from carotid artery.Human decidua tissues were collected by artificial abortion at 6-10 weeks of gestation.The CD4+ T cells were separated by MACS.CD4+ T cells were divided into four groups during cell culture.Group A was treated with 10% fetal calf serum,which was the control group.Group B was treated with 10% of the rat serum from the herbal medicine;Group C was treated with 20% of the rat serum from the herbal medicin.Group D was treated with the rat serum of the saline control.The supernatants were harvested at 24,48 and 72 h of the culture,respectively.The amounts of IL-4 and IFN-? in the culture supernatants were measured by ELISA.Results:In both group B and C of the culture the amount of IL-4 was evidently elevated when compared with the control,group A(P
