Objective To explore the clinical value of hysteroscopy combined with laparoscopy in the diagnosis and treatment of congenital uterine malformation. Method The clinical data of 53 cases with congenital uterine malformation being diagnosed and treated by hysteroscopy combined with laparoscopy were analyzed retrospectively. Results The 53 diagnosed cases included 25 with incomplete uterus septum, 14 with complete uterus septum, 4 with rudimentary horn of uterus, 3 with unicomuate uterus, 2 with bicornuate uterus, 3 with double-uterus, 2 with bicorbate uterus. Hysteroscopy combined with laparoscopy could diagnose the lesions in the uterine and the abdominal cavity, also could rectify the uterine malformation simultaneously. Ultrasound, hysterosalpingography, hysteroscopy all could not diagnose the uterine malformation completely correct, but hysteroscopy combined with laparoscopy could do. Conclusion Hysteroscopy combined with iaparoscopy is safe and effective, which can be the first-line selection for the diagnosis and treatment of congenital uterine malformation.

Objectives To evaluate the fetal blood flow velocity waveforms (FVWs) in relation to the perinatal outcomes. Methods 46 normal term pregnant women and 32 high risk pregnant women were examined with colour doppler ultrasound for their FVWs of umibilical artery (UmA). middle cerebral artery (MCA) and renal artery (RA). Results The resistance index (RI),pulsatile index(PI) and ratio of systolic to diastolic flow velocity(S/D) of UmA and RA were higher and the PI,S/D of MCA were lower significantly in the high risk pregnancy group than that of normal pregnancy group (P

To explore the role and changes of dopamine receptor activity and their subtypes during the onset process of Parkinson disease( PD ), on the basis of 6 hydroxydopamine lesioned PD rat model, radioligand binding assay (RLBA) and Scanchard drawing were used to measure the maximal binding capacity of receptor (Bmax) and equilibrium dissociation constant (KD) of D 1 and D 2 dopamine receptors in caudal putamen of the model and control rats at different time point. The results of RLBA study revealed D 2 dopamine receptor Bmax was significantly increased and KD was significantly decreased in the caudal putamen ipsilateral to the lesion in rat model, and the changes reached the peak in one month rat model group. In contrast, the caudal putamen D 1 receptors were far less affected, with no consistent changes in the same model groups as compared with the control, except that 2 weeks model group showed Bmax was slightly decreased while KD was slightly increased. The study confirms that D 2 dopamine receptor is upregulated in the caudal putamen ipsilateral to the lesion in PD rat model, and the affinity of the receptors is increased, but the activity of D 1 dopamine receptor is not significantly changed.

Objective To investigate the association factors affecting the course of IVF/ICSI-ET. Methods The clinical data of 348 cycles of IVF/ICSI-ET in patients with different causes of infertility were analyzed retrospectively. Results Ovarian reserve and response to stimulation declined with aging. The ability of bFSH predicting ovarian response was low. E 2 peak concentration, number of big follicle and retrieved oocytes decreased significantly when bFSH concentration evelated. The number of big follicle and retrieved oocytes obviously increased with the E 2 peak concentration increasing. The number of antral follicle and volume of ovary were positive relation with ovarian response. None of the factors above could predict the outcome of IVF indenpedently. Conclusion Age was strongly associated with ovarian reserve and response. The bFSH level was one of the indices reflecting ovarian reserve, and had the limited capability for predicting ovarian response and IVF outcome.E 2 peak concentration could not predict the IVF consequence. The number of total antral follicle and volume of ovary were the most direct index reflecting ovarian response. The conditions of patients should comprehensively be evaluated to raise the pregnant rate of IVF.

OBJECTIVE: A series of recent studies have demonstrated the mechanism of migration and nerve net of neural stem cells. These theories have further substantiated neural stem cell transplantation. In view of these new findings, this paper reviewed the mode of migration and information of network. The significance of these theories was discussed.DATA SOURCE: We search on Pubmed with the key words "neural stem cell", "migration", and "nerve net", limiting the language to English and publication date from 1970 to 2004. At the same time we searched on CNKI.STUDY SELECTION: We selected the randomized and non-randomized controlled studies related to migration and nerve net building of neural stem cells. Review articles and articles with repetitive studies were excluded.DATA EXTRACTION: Among 39 papers selected, 16 papers concerning the development of this topic were selected, and the others were excluded.DATA SYNTHESIS: For retrograde lesions and severe injury of nervous system, transplantation of nerve stem cells may replace aging degenerative and dead nerve cells and rebuild neural network for the recovery of cerebral function. Migration of nerve cell and network principle can solve the survival, differentiation, migration and creation of nerve network after transplantation of nerve stem cells so as to realize the recovery and reconstruction of cerebral function.CONCLUSION: Neural stem cells can migrate to intended places and can build nerve net under some conditions, which will be useful for medicine deyelopment.

Objective To investigate the clinical effect of hysteroscopic treatment of septate uterus with Neodymium: YAG laser. Methods Forty-six sterile patients with septate uterus received hysteroscopic metroplasty with Nd: YAG laser.The metroplasty was completed under the guidance of B-ultrasonography in 41 patients with incomplete septate uterus,and with the assistance of laparoscopy in other 5 patients with complete septate uterus.Results The metroplasty was successfully conducted on one session in 45 patients,the success rate being 98%(45/46).Postoperative follow-up examinations in 28 patients found pregnancy within 1 year in 20 patients,16 of whom delivered of a viable term infant,the pregnancy rate within 1 year being 71%.Conclusions Hysteroscopic treatment of septate uterus with Nd: YAG laser is effective.The uterine neck may not be excessively dilated,the intraoperative bleeding can be thoroughly controlled,and the procedure under general anesthesia is relatively safe.

Objective To know prevalence of depression, its coping strategies and risk factors among infertile women with in vitro fertilization and embryo transfer (IVF-ET) or intracytoplasmic sperm injection. Methods Infertile women with IVF-ET were interviewed with center for epidemiologic studies short depression scale (CES-D10) and an abbreviated version of the COPE inventory (brief COPE), and their basal sex hormone values and estradiol ( E2 ) on the day of human chorionic gonadotropin (HCG) administration were monitored, as well as the number of oocytes yielded was counted. Results Prevalence of depression was 20.6% in infertile women, higher in those with more than eight years of marriage, infertility for more than six years, and receiving treatment for at least three years. Risk of depression among the women of infertility with monthly family income less than 3000 yuan was 14 times as those with more than 3000 yuan and risk of depression among them due to the factors of their husbands was 2/5 as those not due to men's. Depressive symptoms in the women increased with increasing of their basal follicle stimulating hormone (FSH) level, counted egg number and scores of denial items. Occurrence of their depressive symptoms decreased with higher basal E2 levels, and scores of substance use and humor. Conclusions Some infertile women with IVF-ET do have depression and preventive intervention should be aimed at related factors for depression to improve their psychological health.

Effect and safety of repeated embryo aspiration for reduction of muhifetal cervical pregnancy Was retrospectively evaluated.Three women with muhifetal cervical pregnancy successfully received conservative treatment of repeated embryo aspiration under the guidance of transvaginal ultrasound,and the gestational sac contents were aspirated completely.Local(2.5～5.0 mg injectable methotrexate,MTX) or systemic medication was used.Our findings showed that repeated embryo aspiration for reduction of cervical multifetal pregnancy could improve the coupe of disease,decrease systemic medication of MTX,and discontinue a cervical pregnancy within 8 weeks effectively and safely.However,the mminimum therapeutic dose of MTX remained to be explored.

Objective:To study the relationship between luteinizing hormone(LH) ?-subunit gene Gly102Ser polymorphism and polycystic ovary syndrome and premature ovarian failure. Methods: The LH? gene Gly102Ser polymorphism was analyzed in polycystic ovary syndrome(70 cases),premature ovarian failure(34 cases) and normal group(90 cases) by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). Results: The LH? gene allelic frequencies of A,G were 0.100, 0.900;0.079,0.921;0.017,0.983 in PCOS,POF and control groups, respectively. The A allele frequencies of LH? gene in PCOS and POF were higher than those in control groups(? 2=10.872,4.413,P0.05). Conclusion: The LH? gene Gly102Ser polymorphism exists in both PCOS and POF people,which is associated with PCOS but not related to POF,and might be a risk factor for PCOS.

Objective To evaluate the characteristics and treatment of ovary torsion after controlled ovarian hyperstimulation.Methods Between Jan.2008 and Dec.2011,5 cases with ovary torsion who underwent ovarian hyperstimulation were retrospectively studied.Results Five cases presented intermittent lower abdominal from I to 38 days after oocyte retrieval.Enlargement of ovary and decreased or absent venous and/or arterial flow were demonstrated by Doppler sonography.Two torsions at left side,two torsions at right side,and one on bilateral side were observed.Three cases give up embryo transplantation,2 cases were pregnant after surgical treatment.One case with partial torsion was successfully treated with simple conservative treatment.Two cases with complete torsion were performed adnexectomy by laparotomy.One case with complete torsion with early pregnancy was managed by laparoscopic adnexectomy.One case with chemical pregnancy was managed by laparoscopic detorsion for left side and excision for right side.Postoperative pathology of ovary tissue all confirmed haemorrhage and necrosis.Conclusions Ovary torsion might occur after controlled ovarian hyperstimulation.The early management on ovary torsion will be benefit for preserving ovarian function.
