Objective To evaluate diagnosis of cord entanglem ent and fetus safety by B ultra-sonic and nemodromometer. Methods 86 pregnant women were diagnosed as cord entanglement in late pregnancy by B ultrasonic examination and Doppler blood flow analysis of the S/D ratio from ma r to May, 1999. The pregnancy outcomes were followed up. Cord entanglement,es -pecially the high blood circulating resistance, suggested that there was h igh risk of fetal distress. The obstetrician would manage the delivery stage pro perly according to the results of Doppler examination.Results 7 2 women were proved cord entanglement after delivery wity coincident rate of 83. 7%. Five women were delivered by cesarean section and forceps among 11 cases of abno rmal S/D ratio, and the rate of operative delivery in group with abnormalS/D rat io was significantly higher than that of the group with normal S/D ratio (P ＜0.05). Conclusions The combined examination can improve the rate of diagnosis of cord entanglement and abnormal S/D ratio, forecast the feta l distress, reduce birth rate of infant with lower Apgar score and reduce the ces arean section rate due to social factor.

Objective To investigate pregnancy complications,cesarean delivery and abnormal fetal presentation in women with uterine anomalies.Methods Fifty women diagnosed with uterine malformation and sixty women with normal uterus were retrospectively analyzed .Results The group comprised women with uterine malformation had significantly higher stillbirth or fetal death (P <0.05) and lower rates of the full-term delivery(P <0.05) than that of the control group.The subgroup comprised women with uterine anomalies had significantly higher rates of cesare -an section(P <0.05) and abnormal fetal position(P <0.05) than the control group.The birth weight and length of infant in observation group were significantly lower than those in control group (P <0.05).The rate of placenta abnormalities in uterine anomalies was significantly higher than that in control group (P <0.05).The incidences of premature rupture of membrane,cord entanglement,oligohydramnios,postpartum hemorrhage and neonatal asphyxia in observation group were no significant difference than those in control group .The rate of premature rupture of membrane(PROM) in uterus unicornis was significantly higher than that in other types (P <0.05).Conclusion Compared with women with normal uterus ,the incidences of abnormal fetal position ,the placenta abnormalities,pre-mature delivery,and stillbirth or fetal death in women with congenital uterine anomalies are high .Uterine anomalies are associated with a decrease in the birth weight and length .We should pay more attention to finding the uterine malformation and treatment before pregnancy .Antenatal care should be reinforced in pregnancy women with uterine anomalies.

Objective To understand the expressions of transforming growth factor ?1(TGF-?1) and its receptors(T?R) in villi and decidua during early pregnancy and their effects on early embryo development, and explore the mechanism of spontaneous abortion. Methods By immunohistochemical technique, expressions of TGF-?1 and its receptors were determined in villi and decidua from 10 cases of spontaneous abortion women after in vitro fertilization and embryo transfer (IVF-ET group), 20 cases of spontaneous abortion women (spontaneous abortion group), and 20 cases of normal early pregnancy women (control group). Results TGF-?1 and its receptors had high expressions in decidua cells, villus glands and interstitial cytoplasm in all three groups. The average light density of the expressions of TGF-?1 in the villi and decidua of IVF-ET, spontaneous abortion and control groups were 0.167 and 0.199, 0.198 and 0.201, 0.277 and 0.274, respectively. The intensity of T?R-Ⅰ in the villi and decidua of IVF-ET, spontaneous abortion and control groups were 0.144 and 0.150, 0.202 and 0.201, 0.238 and 0.281, respectively. And the expressions of T?R-Ⅱ in the villi and decidua of IVF-ET, spontaneous abortion and control groups were 0.199 and 0.145, 0.153 and 0.156, 0.300 and 0.301, respectively. The differences between the control group and both abortion groups were all significant (P

Objective To investigate clinical effect and safety of in vitro maturation(IVM)of human immature oocytes in infertile women with polycystic ovary syndrome by comparing with conventional in vitro fertilization(IVF)and intracytoplasmic sperm injection(ICSI).Methods From Jan.2003 to Dec.2009,157 infertile women with PCOS underwent 162 cycles IVM in Center for Reproductive Medicine,the First Affiliated Hospital of Anhui Medical University.In the mean time,109 patients with PCOS underwent 114 IVF/ICSI cycles as control group 1 and 106 patients with other factors underwent 106 IVF/ICSI cycles as control group 2.Treatment and outcome of pregnancy and infant were compared among those 3 groups.Results No statistically significant difference were found in terms of the positive rate of hCG in urine[35.7％(56/157),42.2％(46/109),44.3％(47/106)],the rate of clinical pregnancy[29.3％ (46/157),37.6％(41/109),41.5％(44/106)],the rate of entopic pregnancy[1.9％(3/157),1.8％ (2/109),0.9％(1/106)],the rate of miscarriage[18.6％(8/43),12.8％(5/39),20.9％(9/43)]and the rate of live-birth[22.3％(35/157),31.2％(34/109),32.1％(34/106)]among three grbups(IVM group,control group 1,control group 2,P ＞ 0.05).The rate of preterm labor,low weight newborn,mean birth weight,ratio of male to female did not show significantly difference among 3 groups(P ＞ 0.05).The average control ovarian stimulation was 6 days,the median dose of gonadotropin(Gn)was 675 IU,and the total hospital cost was(8392 ± 1328)RMB in IVM group,which were statistically lower than those in the other two control groups(P ＜ 0.01).The rate of multiple pregnancy was 4.7％(2/43)and ovarian hyperstimulation syndrome(OHSS)0 in IVM group,which were significantly lower than those in the other control group(P ＜0.01).Conclusion In vitro maturation is an effective treatment in infertile women with PCOS,it could obtain the similar pregnancy outcome and reduce total cost,the dosage of gonadotropinreleasing hormone and rate of OHSS compared with conventional IVF/ICSI.

Objective To evaluate the feasibility and clinical effectiveness of arthroscopic femoral osteoplasty for cam-type femoroacetabular impingenent(FAI).Methods From October 2007 to April 2009,31 patients with cam-type FAI underwent hip arthroscopy,including 12 males and 19 females with an average age of 34.1 years(range,18-45).Physical examination,X-ray,3D-CT scans were carried out preoperatively to make the definite diagnosis.All patients were treated with hip arthroscopic debridement and femoral osteoplasty.The patients were followed-up at 1 month,3 months,6 months,1 year,and every year post operation.Outcomes were measured with pain visual analogue scale(VAS),ROM of hip,impingement tests,α angle and modified Harris hip score at final follow-up.Results All patients were followed up for average 22.7 months(range,18-36).At final follow-up,impingement tests among all patients were negative,the range of flexion increased from 101.0°±14.2° to 121.0°±11.7°,the range of internal rotation in a position of 90° flexion increased from 5.0°±9.8° to 30.1°±12.7°,α angle decreased from 74.2°±10.7° preoperatively to 44.7°±8.3°,VAS pain score decreased from 6.1±1.1 preoperatively to 0.9±0.7,modified Harris hip score improved from 41.2±5.7 preoperatively to 73.6±4.1,all differences were statistically significant.Conclusion Arthroscopic femoral osteoplasty for cam-type FAI can win the satisfactory achievements for complete excision of bony prominence at anterior-lateral femoral head-neck junction,restoration of the femoral offset,significant relief of clinical symptoms and improvement of hip range of motion.

Objective To investigate the association between polymorphism of cytochrome P450 subfamily Ⅺ A polypeptide 1 (CYP11A1) gene and polycystic ovarian syndrome (PCOS) in Chinese population. Methods From May 2005 to Dec.2008,290 PCOS cases treated in the First affiliated hospital of Anhui Medical University matched with 344 reproductive women as controls were enrolled in this study. Genotypes of 7 tagging single nucleotide polymorphisms(tSNP,rs12438594,rs4077582,rs9806234,rsl6968477,rs4887139,rs1843090,rsl 1632698)covering CYP11A1 gene (r~2≥0.8) and 3 microsatellite markers (D15S1547,D16S520,D15S1546) were chosed from the phase II database of Han population in HapMap data.Genotype and frequency of allele were detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and haplotype of gene polymorphism were analyzed in 290 PCOS cases and 344 controls.Results Among 7 tSNPs and 3 microsatellite markers,the frequency of rs4077582,D15S1547,D15S1546 and rsl 1632698 between two groups reached statistical difference (P =0.010,0.044,0.018 and 0.026).The allele frequency of rs4O77582,rs4887139,rsl843090,D15S1547 and Dl 6S520 showed significant difference between two groups(P=0.002,0.048,0.030,0.001 and 0.024).Among 5 haplotype of CYP11A1(ACGCA13/6/9AG,ACGTA16/6/11AA,GCACG12/8/8AA,GTACA14/4/7GG,GTGCA13/6/7AG),the frequency of GTACA14/4/7GG and ACGCA13/6/9AG were 7.8% (45/580) and 25.3% (147/580) in PCOS group and 11.9% and 19.6% in control group,which showed statistical difference (P< 0.05 ).There was no significant difference in the level of serum androgen at difference genotype from rs4077582 between two groups (P>0.05).Conclusion The polymorphism of CYP11A1 gene was associated with PCOS,however,the relationship between gene sequence covered by tSNP/microsatellite markers and hyperandrogenism of PCOS should be further investigated.

Objective To investigate the influence on developmental potential of frozen-thawed rabbit oocytes with double assisted activation followed by intracytoplasmic sperm injection (ICSI). Methods A total of rabbit oocytes were collected and thawed after vitrification cryopreservation. Among all oocytes were cultured for 1 hour followed by ICSI. 156 Survived oocytes were divided into 5 groups randomly. I0634 single activation: 30 oocytes were added with calcium ionomycin ( I0634 ) at 5 μmol/L for 5 minutes;SrCl2single activation: 26 oocytes were added with strontium chloride at 10 mmol/L for 10 minutes;10634 double activation: 33 oocytes were activated by I0634 twice;SrCl2 double activation: 28 oocytes were activated by strontium chloride twice. Control group: 39 oocytes were not added with any activators. The rate of fertilization, cleavage and blastocysts formation were observed and compared between various groups. Result The rates of fertilization, cleavage and blastocysts formation were in group of SrCl2 single activation were higher than those of I0634 single activation group without statistical difference (54% vs. 33%, 27% vs. 17%, 8% vs. 3%, P <0.05 ). However, those above rates in double activation by I0634 were higher significantly than those of single I0634 activation (82% vs. 33%, 55% vs. 17%, 15% vs. 3%, P < 0.05). The rates of fertilization (61%) was higher and the rate of cleavage (21%) and blastocysts formation (7%) were lower in group of SrCl2 double activation in comparison with group of SrCl2 single activation without reaching statistical difference (P<0.05 ). Notably, the rates of fertilization, cleavage and blastocysts formation in I0634 double activation group were higher than those in group of SrCl2 double activation with statistical difference (82% vs. 61%, 55% vs. 21%, 15% vs. 7%, P<0.05). Conclusion It might enhance the potential of fertilization of oocytes and early embryo development treated by double activation following ICSI, however, those activated oocytes demonstrate rapid cleavage.
