ABSTRACT
Congenital vertebral malformation refers to the developmental anomaly of vertebral body during the embryonic stage.Congenital vertebral malformation can cause vertebral kyphosis,scoliosis,spine shortening and other spinal abnormalities as well as thoracic deformities,affecting the quality of life,even threatening the life of the affected children,bringing heavy burden to the family and society.This article reviews the progress in fetal vertebral deformity and its prenatal ultrasound diagnosis.
ABSTRACT
Prenatal 2D and 3D ultrasonographic examinations were performed for 67 008 pregnant women in Renmin Hospital of Wuhan University from January 2013 to December 2016.Among 69 013 fetuses,71 cases of congenital vertebral deformities were diagnosed with a detection rate of 0.103%.There were 40 cases of semi-vertebrae,23 cases of butterfly vertebrae,2 cases of coronal vertebral body fissure and 6 cases of vertebral fusion.Half vertebral deformity was the most common vertebral abnormality accounting for 56.3%(40/71),and the coronal vertebral body fissure was the least abnormality.Among 71 abnormal vertebral fetuses,there were 40 cases with other abnormalities,of which 28 fetuses were induced abortion, 12 fetuses were born;there were 31 cases of simple vertebral body anomalies,of which 8 fetuses were born and 23 fetuses were induced abortion.In infants with a single vertebral anomalies had no significant scoliosis,X-ray examination was performed 3-6 months after birth,the results were consistent with prenatal ultrasound diagnosis.Fifty one cases of induced abortion were examined by X-ray,the prenatal diagnosis was consistent with X-ray findings in 48 cases,and the remaining 3 cases were all multiple hemi-vertebrae with missed diagnosis of congenital butterfly vertebral deformity.
ABSTRACT
The clinical data of 39 cases of intrauterine pregnancy complicated with cornual pregnancy after in-vitro fertilization embryo transfer ( IVF-ET) were analyzed retrospectively .All the patients were diagnosed by transvaginal ultrasound in early pregnancy , and the position of the gestational sac and its external process were determined by transvaginal ultrasound .According to the location and size of the gestational sac, the patients were divided into two groups: in group A (n=29) the gestational sac was located close to the interstitial tube and the gestational sac was larger , prominent out of the corners of the uterus;in group B (n=10) the gestational sac was located towards the uterine cavity , gestational sac was smaller and the embryo was not active .The laparoscopic angle wedge resection for group A and ultrasound-guided embryo reduction for group B were performed respectively .After treatment , 38 cases were stable to term delivery with intrauterine pregnancy; abortion occurred in 1 case of group A 2 weeks after operation . The early diagnosis and treatment is very important for intrauterine pregnancy complicated with cornual pregnancy . Ultrasonography provides an accurate preoperative assessment and intraoperative real -time monitoring during embryo reduction , which provides an alternative approach for the treatment of intrauterine pregnancy combined with cornual pregnancy .

ABSTRACT
To explore the diagnostic values of real-time elastosonography quantitative parameters in uterine fibroids and adenomyoma.The clinical data of 175 cases were analyzed retrospectively.Strain ratios (B/A) of lesion and normal adjacent myometrium were measured and mean B/A was calculated.The average B/A of uterine fibroids and adenomyoma was 3.81 ±0.52 and 1.39 ±0.46 respectively.And there was significant statistic difference (t =2.563,P ＜ 0.05).the accuracy rates of real-time elastosonography in the diagnosis of uterine fibroids and adenomyoma were high at 97.4％ (148/152) and 95.3％ (122/128) respectively.Real-time elastosonography has high diagnostic values for uterine fibroids and adenomyoma.
ABSTRACT
A total of 104 patients with polycystic ovarian changes on ultrasound were divided into polycystic ovary syndrome (PCOS) and polycystic ovaries (PCO) groups according to their clinical symptoms and endocrine examinations.And 40 women with normal ovulation served as the controls.Ovarian volume (OV),ovarian stroma area (SA),ovarian total area (TA) and SA/TA ratio were measured by transvaginal uhrasonography.Their endocrine hormone levels were determined.Patients with PCOS showed significantly higher OV,SA,TA and SA/TA than those of PCO and control groups.SA/TA was positively correlated with testosterone.The median serum levels of anti-Mullerian hormone (AMH) and inhibit B in the PCO group were intermediate between those in control and PCOS groups.AMH and inhibin B of PCOS were higher than the PCO and control groups.It indicated that the levels of AMH and inhibit B were associated with the degree of polycystic ovaries and they could be used to differentiate PCOS and PCO.SA/TA is associated with the elevated serum testosterone of PCO.And SA/TA is an important ultrasonic parameter for diagnosing PCOS.

ABSTRACT
A total of 183 patients of ectopic pregnancy due to tubal factors were divided into the methotrexate (MTX),conservative surgery and salpingectomy groups.The dose of gonadotropin,counts of harvested oocytes and high-quality embryos and pregnancy rate were compared among three groups to analyze the differences of in vitro fertilization and embryo transfer (IVF-ET).And the above parameters showed no significant differences (P ＞0.05 ).The clinical pregnancy rate of the conservative group was higher than the other two groups.And the difference was statistically significant compared with salpingectomy ( P ＜ 0.05 ).It suggested that the treatments of ectopic pregnancy had some effects on the outcome of IVF-ET.The pregnancy rate was slightly higher in the conservative surgery group.
ABSTRACT
Objective To explore the feasibility of laparoscopic-assisted pancreaticoduodenectomy.Methods The clinical data of 5 patients in our hospital from January to May 2010 were analyzed. 2 patients were pre-operatively diagnosed to have lower common bile duct adenocarcinoma, and 2 patients were preoperatively diagnosed to have adenocarcinoma of the descending duodenum, 1 patient was intra-oparatively diagnosed to have pancreatic head cancer. During the operation, laparoscopic exploration was performed, then gallbladder, distant bile duct, distant stomach, duodenum, part of jejunum and head of pancreas were disassociated, then the digestive tract was reconstructed under open abdomen surgery. Results All the operations of the 5 cases were successfully performed, with an average operation time ( 339 ± 54) min and an intra-operative blood loss of (538 ± 106)ml, and there was no intra-operative blood transfusion. The patients'bowel function recovered (4.0 ± 1.0 ) d postoperatively and were discharged ( 15.8 ± 4.7 ) d postoperatively.1 patient developed pancreatic fistula and was cured with conservative treatment. Conclusions Laparoscopicassisted pancreatoduodenectomy is minimally invasive with short operation time and fast postoperative recovery,which is worth of further clinical study.
ABSTRACT
BACKGROUND: Whether overweight and obesity have impact on the outcome of in vitro fertilization and embryo transfer (IVF-ET) treatment remains poorly understood.OBJECTIVE: To investigate the effect of women's body mass index (BMI) on the outcome of IVF-ET treatment. METHODS: A total of 184 cases were divided into 3 groups according to BMI: lankness group (BMI < 18.5 kg/m2), normal group (18.5kg/m2 ≤ BMI < 24 kg/m2), overweight and obesity group (BMI≥ 24 kg/m2). Treatments of ovulation induction and IVF-ET were regularly performed in the Reproductive Medical Center, Renmin Hospital of Wuhan University. The duration and dose of gonadotrophic hormone (GTH) treatment, estradiol level at the day of human chorionic gonadotropin (hCG) injection, and the differences of retrieved oocytes numbers, fertility rate, embryo quality, implantation rate, pregnancy rate and abortion rate were compared.RESULTS AND CONCLUSION: The dose of GTH used was in the overweight and obesity group was greater than that of the other groups (P< 0.05), and the dose was increased with BMI increasing. There was no significant difference in other aspects such as estradiol level, retrieved oocytes numbers, fertility rate, embryo quality, implantation rate, pregnancy rate and abortion rate at the day of hCG injection among the three groups (P> 0.05). All results demonstrated that overweight and obese patients require a higher hCG dose to achieve follicular maturation than normal weight patients. However, overweight and obesity does not affect negatively results of IVF-ET.
ABSTRACT
BACKGROUND: Considerable debate exists which factors influence the outcomes of the vitrified frozen-thawed embryo transfer because lack of clinical applications.OBJECTIVE: To explore the factors influencing the outcomes of the vitrified frozen-thawed embryo transfer in assisted reproductive technology.METHODS: A retrospective statistical analysis was performed in Reproductive Medicine Center, Renmin Hospital of Wuhan University of 142 patients, 154 thawing cycles. The patients were grouped according to the age of patients, embryonic development, fertilization methods, endometrial preparation programs, the endometrial thickness, the process of transplantation and the survival cell ratio of embryo recovery, the implantation rate and clinical pregnancy rate were compared between various groups.RESULTS AND CONCLUSION: Among the groups of the different age, fertilization methods, endometrial preparation programs, endometrial thickness and the process of embryo transfer embryo implantation rate and clinical pregnancy rate were no significant difference (P > 0.05); between the two groups of the second day fertilized embryos (D2) and the third day (D3)fertilized embryos, the clinical pregnancy rate was not significant (P> 0.05), but the embryo implantation rate of D3 group was significantly higher than D2 group. The survival cell ratio of embryo recovery has a significant effect on implantation rate and clinical pregnancy rate (P < 0.05). Ln the frozen-thawed embryo transfer cycles, embryo quality plays a major role in pregnancy rate, and preparation for appropriate endometrial thickness can improve the clinical pregnancy rate.
