Abstract
Hydroformylation of olefins is widely used in the chemical industry due to its versatility and the ability to produce valuable aldehydes with 100% atom economy. Herein, a hybrid phosphate promoter was found to efficiently promote rhodium-catalyzed hydroformylation of styrenes under remarkably mild conditions with high regioselectivities. Preliminary mechanistic studies revealed that the weak coordination between the Rhodium and the P=O double bond of this pentavalent phosphate likely induced exceptional reactivity and high ratios of branched aldehydes to linear products.

Abstract
PURPOSE To assess the consistency of Ovarian-Adnexal Reporting and Data System (O-RADS) lexicon interpretation between senior and junior sonologists and to investigate its impact on O-RADS classification and diagnostic performance. METHODS We prospectively studied 620 patients with adnexal lesions, all of whom underwent transvaginal or transrectal ultrasound performed by a senior sonologist (R1) who selected the O-RADS lexicon description and O-RADS category for the lesion after the examination. Meanwhile, the junior sonologist (R2) analyzed the images retained by R1 and divided the lesion in the same way. Pathological findings were used as a reference standard. kappa (к) statistics were used to assess the interobserver agreement. RESULTS Of the 620 adnexal lesions, 532 were benign and 88 were malignant. When using the O-RADS lexicon, R1 and R2 had almost perfect agreement regarding lesion category, external contour of solid lesions, presence of papillary inside cystic lesions, and fluid echogenicity (к: 0.81-1.00). Substantial agreement in solid components, acoustic shadow, vascularity and O-RADS categories (к: 0.61-0.80). Consistency in classifying classic benign lesions in the O-RADS category was only moderate (к = 0.535). No significant difference in diagnostic performance between them using O-RADS (P = 0.1211). CONCLUSION There was good agreement between senior and junior sonologists in the interpretation of the O-RADS lexicon and in the classification of O-RADS, except for a moderate agreement in the interpretation and classification of classic benign lesions. Differences in O-RADS category delineation between sonologists had no significant effect on the diagnostic performance of O-RADS.

Abstract
The palladium-catalyzed intramolecular hydroaminocarbonylation of 2-(1-methylvinyl)aniline derivatives has been achieved using dppp (1,3-bis(diphenylphosphino)propane) as a ligand under hydrogen-free conditions. The reaction involves the generation of an active palladium hydride species with a catalytic amount of TsOH. This amide bond formation reaction was applied to the synthesis of various 4-substituted 3,4-dihydroquinolone derivatives with both high yield and regioselectivity.

Abstract
Natural product dimers have intriguing structural features and often have remarkable pharmacological activities. We report here two uncommon marine gorgonian-derived symmetric dimers, weizhouochrones A (1) and B (2), with indenone-derived monomers, that were isolated from the coral Anthogorgia ochracea collected from the South China Sea. These dimers are difficult targets for structure elucidation that solely relies upon conventional NMR data such as NOEs and J-couplings. Here, to explore the application of emerging methods on the structure elucidation of challenging molecules, we explored a number of different anisotropic and computational NMR approaches. The measurements of anisotropic NMR parameters of weizhouochrone A, including residual dipolar couplings (RDCs) and residual chemical shift anisotropy (RCSA), allowed us to successfully determine the planar structure and its relative configuration. This result was corroborated by a computational NMR analysis based on DP4+ probability and computer-assisted 3D structure elucidation (CASE-3D).

Abstract
ObjectiveTo evaluate the feasibility of 9. 4-T postmortem MRI (pm-MRI) for assessment of major congenital heart defects (CHD) cases terminated in the early stage of gestation.MethodsFetuses with CHD detected by the detailed first-trimester ultrasound scan and terminated before 18 gestational weeks were recruited between January 2018 and June 2020. All fetuses were offered 9.4-T pm-MRI examinations and those terminated over 13+6 weeks were offered conventional autopsies simultaneously. Findings of pm-MRI were compared with those of conventional autopsy and prenatal ultrasound.ResultsA total of 19 fetuses with major CHD were analyzed, including 6 cases of the atrioventricular septal defect, 5 cases of Tetralogy of Fallot, 3 cases of hypoplastic left heart syndrome, 1 case of tricuspid atresia, 1 case of transposition of the great arteries, 1 case of severe tricuspid regurgitation, and 2 cases of complex CHD. Pm-MRI had concordant findings in 73.7% (14/19) cases, discordant findings in 15.8% (3/19) cases, and additional findings in 10.5% (2/19) cases when compared with prenatal ultrasound. Pm-MRI findings were concordant with autopsy in all 8 CHD cases terminated over 13+6 weeks.ConclusionIt is feasible to exhibit the structure of fetal heart terminated in the first trimester clearly on 9.4-T pm-MRI with an optimized scanning protocol. High-field pm-MRI could provide medical imaging information of CHD for those terminated in the early stage of gestation, especially for those limited by conventional autopsy.

Abstract
OBJECTIVE To present the experience on prenatal features of 17q12 microdeletion and microduplication syndromes. MATERIALS AND METHODS Prenatal chromosomal microarray analysis (CMA) were conducted between January 2015 and December 2018 at a single Chinese tertiary medical centre. Information of cases identified with 17q12 microdeletion or microduplication syndromes were retrospectively collected. Foetal ultrasonographic findings were reviewed, and other information about the gestation week at diagnosis, inheritance and pregnancy outcomes were also included. RESULTS Ten pregnancies with 17q12 microdeletion and 4 with 17q12 microduplication were identified. The copy number variation (CNV) sizes were 1.39-1.94 Mb in the deleted cases and 1.42-1.48 Mb in the duplicated cases, respectively. All the duplicated and deleted regions included HNF1B and LHX1 genes. Most individuals with 17q12 deletion presented kidney anomalies (9/10), with renal hyperechogenicity being the most common finding (7/10). Fetuses with 17q12 duplication presented a wide phenotypic spectrum, including "double bubble" sign, structural anomalies of the heart and growth anomalies. CONCLUSIONS Our experience further demonstrated the high correlation between 17q12 microdeletion and renal anomalies especially hyperechogenic kidneys. Structural anomalies of the heart were newly identified phenotypes of 17q12 duplication during prenatal period. Besides, growth anomalies and duodenal atresia might be associated with the duplication.

Abstract
PURPOSE To summarize the outcomes of different surgical treatment modalities for cesarean scar pregnancy (CSP) at a single institution over 8 years. METHODS A case series of patients diagnosed with CSP who were admitted to Nanjing Drum Tower Hospital from January 2011 to December 2018 was retrospectively studied. Medical records of all the patients were carefully reviewed. Data on patient demographics, pregnancy characteristics, treatment modalities, response to therapy, and subsequent pregnancy outcomes were collected and analyzed. RESULTS A total of 117 patients undergoing surgical treatments for CSP were included. Thirty-three patients (28.21%) underwent ultrasound-guided curettage; while, 74 (63.25%) and 10 (8.55%) patients received laparoscopy-monitored curettage and laparoscopic CSP resection, respectively. Most of the patients (21/33) who underwent ultrasound-guided surgery had type I CSP; while, 54 out of 84 patients who opted for laparoscopic surgeries had type II CSP. Eleven women underwent a uterine artery embolization procedure before the operation. There was no difference in the use of an intrauterine balloon for hemostasis among the three groups. Only 8 patients needed additional systemic methotrexate treatment. Twenty-four out of 57 women (42.11%) succeeded in conceiving again and gave birth to 21 healthy babies. Only 1 woman (1/24, 4.17%) experienced recurrence of CSP. CONCLUSIONS These data indicated the safety and efficiency of ultrasound-guided curettage, laparoscopy-monitored curettage, and laparoscopic CSP resection for the treatment of CSP.

Abstract
Objective: To explore the relationship between fetal nuchal translucency (NT) in the first trimester and pregnancy outcome. Methods: A prospective cohort study was conducted in Nanjjing Drum Tower Hospital from December 2015 to December 2018, 4 958 singleton pregnant women were enrolled to screen fetal ultrasound structure and serology in the first trimester, ultrasound in the second trimester and neonatus physical examination 28 days after birth. According to the results of NT, 167 cases of fetus with increased NT (≥3.0 mm) and 4 791 cases of normal NT were divided, moreover, 86 cases with isolate increased NT and 81 cases of increased NT combined with structural abnormality. The prognosis of fetuses with different NT thickness was analyzed, and the pregnancy outcome of fetuses with isolate increased NT or combined with structural abnormality were analyzed. In the first trimester, if the fetal structure was abnormal or the serological screening result was high risk, the chromosomal microarray analysis (CMA) would be performed by chorionic villus sampling to determine the prenatal diagnosis. Results: (1) The pregnancy outcome for fetus of normal NT: there were 4 791 cases with normal NT. Totally, 4 726 cases with normal NT and no structural abnormalities were screened out in the firsttrimester. In this group, 5 cases of aneuploidies were diagnosed based on high risk of maternal serum biomarkers and 83 cases of structural abnormalities were screened out in the subsequent ultrasound scan and the neonatal examination. Another 65 cases with normal NT present complicated with structural anomalies were screened out in the first trimester and 4 cases were diagnosed as aneuploidies. (2) The pregnancy outcome for fetus of isolate increased NT: 66 (76.7%, 66/86) cases of isolated increased NT were performed CMA, 3 cases were diagnosed as trisomy 21 and terminated pregnancy. Another 4 cases were terminated pregnancy privately without cytogenetic diagnosis. No further anomalies were found in 79 cases till 6 to 21 months postnatally. (3) The pregnancy outcome for fetus of increased NT with structural anomalies: increased NT present with structural anomalies were screened out by detailed anomaly scan in the first trimester and 32 of them were confirmed as aneuploidies. In this group, 70 cases terminated pregnancy, 2 cases had spontaneous miscarriages and 9 cases had liveborns (1 newborn was found ventricular septal defect). (4) The pregnancy outcome for fetus of increased NT with or without structural anomalies: the percentage of aneuploidies in fetuses with isolated increased NT (3.5%, 3/86) was significantly lower than those with structural abnormalities (39.5%,32/81). The healthy survival rate in fetuses with isolated increased NT (91.9%,79/86) was significantly higher than those with structural abnormalities (9.9%, 8/81). Conclusions: A detailed first-trimester anomaly scan could improve prenatal screening efficiency of birth defects. Compared to the fetuses with increased NT combined with structural abnormalities, the healthy survival rate of fetuses with isolated increased NT based on detailed first-trimester anomaly scan is higher and the percentage of fetal aneuploidies is lower.

Abstract
Benzoxepane derivatives were designed and synthesized, and one hit compound emerged as being effective in vitro with low toxicity. In vivo, this hit compound ameliorated both sickness behavior through anti-inflammation in LPS-induced neuroinflammatory mice model and cerebral ischemic injury through anti-neuroinflammation in rats subjected to transient middle cerebral artery occlusion. Target fishing for the hit compound using photoaffinity probes led to identification of PKM2 as the target protein responsible for anti-inflammatory effect of the hit compound. Furthermore, the hit exhibited an anti-neuroinflammatory effect in vitro and in vivo by inhibiting PKM2-mediated glycolysis and NLRP3 activation, indicating PKM2 as a novel target for neuroinflammation and its related brain disorders. This hit compound has a better safety profile compared to shikonin, a reported PKM2 inhibitor, identifying it as a lead compound in targeting PKM2 for the treatment of inflammation-related diseases.

Abstract
Intrauterine adhesion (IUA) is a common cause of uterine infertility and one of the most severe clinical features is endometrial fibrosis namely endometrial scarring for which there are few cures currently. Blocked angiogenesis is the main pathological change in the scarred endometrium. The fibroblast growth factor 2 (bFGF), a member of FGF family, is usually applied to promote healing of refractory ulcer and contributes to angiogenesis of tissues. In this study, the sustained-release system of bFGF 100 µg was administrated around scarred endometrium guiding by ultrasound every 4 weeks in 18 patients (2-4 times). Results showed that after treatment, the menstrual blood volume, endometrial thickness and the scarred endometrial area were improved. Histological study showed blood vessel density increased obviously. Three patients (3/18) achieved pregnancy over 20 gestational weeks. Therefore, administrating the bFGF surrounding scarred endometrium may provide a new therapeutic approach for the patients with endometrial fibrosis.

Abstract
Two new highly oxygenated ergostane-type sterols (1, 2) together with one known related compound sinugrandisterol A (3) were isolated from the soft coral Sinularia sp. collected from the water area near the Xisha Islands, South China Sea. Their structures were elucidated on the basis of detailed spectroscopic analysis, chemical transformations, and by comparison with those reported in literature. In bioassays, compounds 1 and 2 showed in vitro antiproliferative activity against a panel of cancer cell lines, including MDA-MB-436, A549, Hep3B, HT-29 and H157. Morphological observation and Hoechst 33,258 staining assays showed that compound 1-treated H157 cells displayed apoptosis characteristics. Moreover, western blot assays suggested that 1 could increase the expression of Bax and down-regulate expression of Bcl-2.

Abstract
OBJECTIVE To estimate the potential value of fetal assessment for the cardiac axis (CAx) and V-sign angle (VSA) in the first trimester in the prediction of fetal major cardiac defects. METHODS A cohort study was conducted from December 2015 to June 2016. Patients with singleton pregnancies and crown-rump length from 45 to 84 mm were recruited to undergo nuchal translucency sonography. The CAx on the 4-chamber view and the VSA on the 3-vessel and trachea view with Doppler mapping were measured. The estimated performance of different combinations of increased fetal nuchal translucency, CAx, and VSA in screening for major cardiac defects was examined. RESULTS The study population of fetuses included 30 fetuses with major cardiac defects and 1538 normal fetuses. The CAx and VSA were 30° to 60° and 30° to 40°, respectively, according to the 2.5th and 97.5th percentiles in normal fetuses. When cases of isolated septal wall defects and an isolated right aortic arch were excluded, nuchal translucency above the 95th percentile, an abnormal CAx, and an abnormal VSA were observed in 63.3% (19 of 30), 63.3% (19 of 30), and 66.7% (20 of 30) of fetuses with major cardiac defects, respectively, and in 4.6% (71 of 1538), 2.0% (30 of 1538), and 5.6% (86 of 1538) of those without cardiac defects. Either an abnormal CAx or VSA was found in 93.3% (28 of 30) of the fetuses with cardiac defects and in 7.3% (113 of 1538) of those without cardiac defects. CONCLUSION Assessment of the CAx and VSA is helpful in defining a population at risk for major cardiac defects in the first trimester.

Abstract
Premature ovarian failure (POF) is a refractory disease for clinical treatment with the goal of restoring fertility. In this study, umbilical cord mesenchymal stem cells on a collagen scaffold (collagen/UC-MSCs) can activate primordial follicles in vitro via phosphorylation of FOXO3a and FOXO1. Transplantation of collagen/UC-MSCs to the ovaries of POF patients rescued overall ovarian function, evidenced by elevated estradiol concentrations, improved follicular development, and increased number of antral follicles. Successful clinical pregnancy was achieved in women with POF after transplantation of collagen/UC-MSCs or UC-MSCs. In summary, collagen/UC-MSC transplantation may provide an effective treatment for POF.

Abstract
PURPOSE To monitor early response for locally advanced cervical cancers undergoing concurrent chemo-radiotherapy (CCRT) by ultrasonic histogram. METHODS B-mode ultrasound examinations were performed at 4 time points in thirty-four patients during CCRT. Six ultrasonic histogram parameters were used to assess the echogenicity, homogeneity and heterogeneity of tumors. RESULTS Ipeak increased rapidly since the first week after therapy initiation, whereas Wlow, Whigh and Ahigh changed significantly at the second week. The average ultrasonic histogram progressively moved toward the right and converted into more symmetrical shape. CONCLUSION Ultrasonic histogram could be served as a potential marker to monitor early response during CCRT.

Abstract
Background Three-dimensional power Doppler ultrasound (3D-PDU) imaging has been widely applied to the differentiation of benign and malignant cervical lesions; however, its potential value for predicting response to chemo-radiotherapy has not been fully explored. Purpose To investigate the feasibility of 3D-PDU imaging in predicting treatment response in patients receiving concurrent chemo-radiotherapy (CCRT) for advanced cervical cancer. Material and Methods Fifty-two patients with advanced cervical cancer who received CCRT underwent 3D-PDU examinations at four timepoints: pre-therapy (baseline), 1 week and 2 weeks during, as well as immediately post CCRT. Final tumor response was determined by change in tumor size using magnetic resonance imaging (MRI). Cervical tumor volumes and vascular indices were calculated and compared with the clinical outcome. Results Of the 52 patients, 32 patients who completed all four examinations were included in the analyses: 21 were classified as complete response (CR) and 11 as partial response (PR). During the treatment, the CR group showed that 3D vascular indices (VI and VFI) significantly increased at 1 week ( P = 0.028, P = 0.017, respectively) then decreased at 2 weeks and obviously decreased at therapy completion (both P < 0.001), whereas tumors significantly decreased in volume at 2 weeks after therapy initiation ( P < 0.05). However, no significant differences in 3D vascular indices values were seen in the PR group during the treatment course (all P > 0.05). Conclusion Prospective longitudinal 3D-PDU imaging may have potentials in monitoring early therapeutic response to CCRT in patients with cervical cancer.

Abstract
Background To investigate the feasibility of strain elastography imaging in early detecting and predicting treatment response in patients receiving concurrent chemo-radiotherapy (CCRT) for locally advanced cervical cancer. Methods Between January 2015 and June 2016, 47 patients with locally advanced cervical cancer were enrolled in a feasibility study approved by the institutional review board. All patients underwent CCRT and received strain elastography examinations at 4 time points: pre-therapy (baseline), 1 week and 2 weeks during, as well as immediately post CCRT. Treatment response was evaluated by MRI at the time of diagnosis and immediately after CCRT. Based on the MRI findings, the treatment outcome was characterized as complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD). Strain ratio of the normal parametrial tissue vs. cervical tumor was calculated and compared with the clinical outcome. Results Out of the 47 patients, 36 patients who completed all 4 examinations were included in the analyses: 25 were classified as CR, 11 as PR, and 0 in the SD/PD groups. Strain ratios were significantly different among the time points in both the CR group (F = 87.004, p < 0.001) and PR group (F = 38.317, p < 0.001). Strain ratios were significantly difference between the CR and PR groups (F = 7.203 p = 0.011). Strain ratios between the CR group and PR group were significantly different at 1 week after treatment initiation (p < 0.05). Compared to the baseline, a significant decrease in the CR group was observed at week 1, week 2 and post treatment (all p < 0.001), while a significant decrease in the PR group was shown in week 2 and post treatment (both p < 0.05), but not at week 1 during CCRT (p = 0.084). Conclusions We have conducted a prospective longitudinal study to evaluate tumor response in women receiving CCRT for cervical cancers. This study has demonstrated the potential of strain elastography imaging in monitoring and early predicting tumor response induced by CCRT.

Abstract
OBJECTIVE To report on a sporadic case of Lowe syndrome diagnosed prenatally with ultrasound examination and genetic testing. METHODS Detailed sonographic fetal screening was performed by an experienced sonographer at 32 weeks of gestation. Fetal cranial magnetic resonance imaging (MRI) was applied to detect potential brain abnormality. Chromosomal microarray analysis (CMA) was conducted on amniotic fluid sample from the fetus and peripheral blood sample from the mother. RESULTS Congenital cataract and enlarged posterior fossa were detected by fetal ultrasound screening. Fetal cranial MRI found hypoplasia of the gyrus. CMA revealed that the fetus has carried a 633 kb deletion at Xq25-26.1 which encompassed the OCRL gene. The mother was a carrier of the same deletion. Clinical examination after birth confirmed that the neonate was affected with Lowe syndrome in addition with an atrial septal defect. CONCLUSION Prenatal diagnosis of Lowe syndrome without a family history largely depends on fetal imaging. Should cataract be found by ultrasound screening, fetal MRI may be considered to rule out central nervous system anomalies. CMA assay should also be considered to facilitate the diagnosis.

Abstract
BACKGROUND Cytomegalovirus (CMV) is a significant cause of fetal abnormalities in developed world. Whether this could be applied in developing world remains unknown. OBJECTIVES To investigate CMV infection in severe fetal malformations in China. STUDY DESIGN During 2007-2014, 436 fetuses (237 males) with severe malformations and terminated pregnancy at median gestational age of 26(+1) weeks were enrolled. CMV DNA was detected in fetal kidneys and other tissues by real-time PCR, and CMV IgG and IgM were measured by ELISA. RESULTS CMV DNA was positive in kidneys and other tissues of seven (1.60%) fetuses. Hematoxylin-eosin staining showed intranuclear and intracytoplasmic inclusion bodies in kidneys of three fetuses, which was also positive for CMV antigens in immunohistochemistry. CMV DNA was found in 5 (6.1%) of 82 fetuses with central nervous system anomalies, 1 (11.1%) of 9 fetuses with abdominal anomalies, 1 (0.59%) of 168 fetuses with multiple congenital malformations, and none of fetuses with other anomalies (177). Of 293 pregnant women with plasma available, 279 (95.2%) were CMV IgG positive only and 6 (2.1%) were CMV IgG and IgM positive. Of 5 mothers with infected fetuses 1 (20%) was CMV IgG and IgM positive, while 5 (1.7%) of 288 mothers with uninfected fetuses were positive respectively (P=0.099). CONCLUSIONS Congenital CMV infection in fetuses with severe congenital malformations is rare, indicating no close association between CMV infection and severe fetal malformations in China. Maternal screening for CMV may have minimal value in identifying fetal malformations in developing world.

Abstract
OBJECTIVE To determine the type and frequency of pathogenic chromosomal abnormalities in fetuses diagnosed with congenital heart disease (CHD) using chromosomal microarray analysis (CMA) and validate next-generation sequencing as an alternative diagnostic method. METHOD Chromosomal aneuploidies and submicroscopic copy number variations (CNVs) were identified in amniocytes DNA samples from CHD fetuses using high-resolution CMA and copy number variation sequencing (CNV-Seq). RESULT Overall, 21 of 115 CHD fetuses (18.3%) referred for CMA had a pathogenic chromosomal anomaly. In six of 73 fetuses (8.2%) with an isolated CHD, CMA identified two cases of DiGeorge syndrome, and one case each of 1q21.1 microdeletion, 16p11.2 microdeletion and Angelman/Prader Willi syndromes, and 22q11.21 microduplication syndrome. In 12 of 42 fetuses (28.6%) with CHD and additional structural abnormalities, CMA identified eight whole or partial trisomies (19.0%), five CNVs (11.9%) associated with DiGeorge, Wolf-Hirschhorn, Miller-Dieker, Cri du Chat and Blepharophimosis, Ptosis, and Epicanthus Inversus syndromes and four other rare pathogenic CNVs (9.5%). Overall, there was a 100% diagnostic concordance between CMA and CNV-Seq for detecting all 21 pathogenic chromosomal abnormalities associated with CHD. CONCLUSION CMA and CNV-Seq are reliable and accurate prenatal techniques for identifying pathogenic fetal chromosomal abnormalities associated with cardiac defects. © 2016 John Wiley & Sons, Ltd.

Abstract
OBJECTIVE To explore the genetic cause for a fetus with structural anomaly, and to correlate the phenotype with the genotype. METHODS Amniotic fluid was obtained following the revelation of structural anomaly by ultrasonography. Cell culture and direct DNA extraction were performed in parallel. G-banded karyotyping analysis and chromosome microarray analysis (CMA) were subsequently carried out. RESULTS G-banded karyotyping has suggested the fetus to be a normal male. However, CMA analysis has revealed the presence of a mosaic 3.24 Mb duplication of 1p36.33p36.32 (24%) and uniparental disomy (UPD) of chromosome 6. The genetic diagnosis for the fetus was therefore 46,XY, arr 1p36.33 p36.32(849,466-4,090,472)×2-3, (6)×2 hmz. The anomaly can probably explain the ultrasound findings in the fetus. CONCLUSION Compared with conventional cytogenetic methods, CMA has greater resolution and throughput, and can serve as a more efficient platform for the detection of chromosomal microdeletion, microduplication, loss of heterozygosity and UPD.

Abstract
Objective This study aimed to determine the optimal Foley catheter balloon volume (30-mL vs. 80-mL) and the maximum time for cervical ripening (12 hours vs. 24 hours) to improve vaginal delivery rate within 24 hours of induction. Methods We conducted an open-label, randomized controlled trial in a teaching hospital in China. Women with a term singleton pregnancy, cephalic presentation, intact membrane and an unfavorable cervix (Bishop score <6) were randomly allocated, in 1:1:1:1 ratio, to receive either one of the four treatments: (1) 30-mL balloon for a maximum of 12 hours, (2) 30-mL balloon for a maximum of 24 hours, (3) 80-mL balloon for a maximum of 12 hours, and (4) 80-mL balloon for a maximum of 24 hours. The primary outcome was vaginal delivery within 24 hours. Secondary outcomes included cesarean section rate and maternal/neonatal morbidity. Data were analyzed on a per-protocol basis. Results Five hundred and four women were recruited and randomized (126 women in each group); nine women did not receive the assigned intervention. More women achieved vaginal delivery within 24 hours in 12-hour Foley catheter groups than in the 24-hour Foley catheter groups (30-mL/12 hours: 54.5%, 30-mL/24 hours: 33.1%, 80-mL/12 hours: 46.4%, 80-mL/24 hours: 24.0%, p < 0.001). Cesarean section rates and the incidence of chorioaminonitis were comparable among four groups. After adjustment for confounding factors, both ripening time and balloon size did not affect the proportion of women delivered vaginally within 24 hours of induction. Conclusion For women with an unfavorable cervix at term, induction of labor with a Foley catheter is safe and effective. Higher balloon volume (80-mL vs. 30-mL) and longer ripening time (24 hours vs. 12 hours) would not shorten induction to delivery interval or reduce cesarean section rate.

Abstract
Minimal deviation adenocarcinoma (MDA) of the uterine cervix, otherwise known as adenoma malignum, is a rare variant of cervical adenocarcinoma, which represents a diagnostic challenge in the field of gynecologic oncology, due to its benign-resembling histological characteristics. To achieve a better understanding of this disease, we present two cases of MDA: one case presented with profuse watery discharge and cervical enlargement, accompanied by retention cysts and hardening; the other presented with a history of myoma cervicis uteri. Both patients underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy and pelvic lymphadenectomy and our follow-up indicated that the patients were still free of any disease. Subsequently, a literature review was performed and the results demonstrated that early diagnosis, clinical stage and surgical protocols are the main factors affecting the prognosis of MDA. Close follow-up of the cases may provide more information regarding this disease and the efficacy of the available therapeutic methods.

Abstract
BACKGROUND The second-trimester maternal serum screening in twin pregnancy is still controversial, as the serum marker levels in twins are not as clear as those in singletons. This study aimed to evaluate the relationship between the levels of the second-trimester maternal serum free beta-human chorionic gonadotropin (free beta-HCG) and alpha-fetoprotein (AFP) in normal twin and singleton pregnancies and to estimate feasible analysis methods for utilizing these markers in second trimester screening for twin pregnancy. METHODS On the basis of a prospective population-based study of second-trimester maternal serum screening, the concentrations of maternal serum AFP and free beta-HCG of 195 normal twin pregnancy and 26,512 singleton controls at gestational weeks 15 to 20 were measured by time-resolved fluoroimmunoassay in one laboratory. The levels of markers were compared between the twins and singletons using weight-correction and gestational age-specific model. RESULTS According to the research protocol, 95 communities were randomly sampled, which covered the whole Jiangsu province, the east of China. A total of 26 803 pregnant women (98%), from the target population accepted prenatal screening for maternal serum AFP, beta-HCG detection, and all babies were followed up for at least six months. There were 197 (0.73%) twin pregnancies, of which one case had fetal trisomy 18, and one case with fetal anencephaly. The others were normal twin pregnancy. From a total enrollment of 26 803 women participants, 26 512 women with normal singleton pregnancies were selected as the model controls. The other 291 pregnancies, including trisomy 21, neural tube defect (NTD), trisomy 18, and other fetal abnormalities, were excluded. No significant differences were found in the medians of gestational age-specific maternal serum free beta-hCG and AFP in normal twin pregnancy comparing with twice those in model controls with the exception of the medians for free beta-hCG during the 16th gestational week (P = 0.012). CONCLUSION The weight-correction and gestational age-specific levels of Chinese Han population maternal serum free beta-hCG and AFP in normal twins were twice the levels as those in the singleton controls during the 17-19 gestational weeks.

Abstract
OBJECTIVE To investigate the clinical utility of multiplex ligation-dependent probe amplification (MLPA) for detecting 22q11 deletion and duplication in congenital heart disease (CHD) cases and to study the incidence of 22q11 deletion and duplicaton in different kinds of CHD. METHODS Forty eight probes of which 25 located in 22q11 low copy number region (LCR 22s A-H), 7 in 22q11 surrounding region (CES, 22q13) and 16 in chromosomes 4, 8, 10 and 17 were selected to detect 22q11 deletion and duplication in 181 preoperative children with CHD and 14 fetuses with serious CHD or CHD with multiple malformations. In these cases, karyotype analysis was also performed. RESULTS MLPA demonstrated that 7 cases had 22q11 deletion [6 cases from CLTCL1 to LZTR1(LCR A-D) and 1 case from CLTCL1 to PCQAP (LCR A-C)] and that 1 case had 22q11 duplication,spanning from ZNF74 to LZTR1(LCR B-D). The phenotypes of heart defect included ventricular septal defect, atrioventricular septal defect, pulmonary stenosis and tetralogy of Fallot. Karyotype analysis showed that 1 case had 21q deletion [46, XY, 21q], 1 case had mosaic trisomy 8 [47,XY, +8/46, XY(1:2)] and 4 cases had trisomy 21. One of the 4 cases with trisomy 21 had concurrent 22q11 duplication. CONCLUSIONS MLPA is a rapid, sensitive, site specific and relatively inexpensive method for diagnosis of 22q11 deletion and duplication in CHD. 22q11 deletion and duplication may cause various kinds of CHD, suggesting that genetic detection should be performed routinely in CHD patients.

Abstract
OBJECTIVE To investigate the application of "Guidelines for performing fetal cardiac scan", issued by the International Society of Ultrasound in Obstetrics and Gynecology in 2006, in prenatal screening of fetal congenital heart disease (CHD). METHOD Totally, 5000 singleton pregnancies presented at the Maternal-Fetal Medical Center of the Affiliated Drum Tower Hospital of Nanjing University Medical School from September 2006 to July 2007, for prenatal screening were included in this study, with the median maternal age of 28 (range, 18 approximately 48) and the median gestation of 27 (range, 18 approximately 40) weeks. Ultrasound screenings were performed on each fetal heart according to "Guidelines for performing fetal cardiac scan" via the four-chamber and outflow tracts & three-vessel views and fetal echocardiographies were further conducted for suspected cases. Once congenital heart disease was confirmed, amniocentesis or cordocentesis was suggested for fetal karyotyping for ongoing pregnancies and autopsy was performed when the pregnancy was terminated after formal consent. Born babies were followed up at 2 approximately 6 months of age using echocardiography. RESULT The four-chamber views were successfully obtained in 97.64% (4882/5000) of all the pregnancies, among which the left ventricular and right ventricular outflow tracts and three-vessel views were obtained in 87.69% (4281/4882), 82.51% (4028/4882) and 96.29% (4701/4882), respectively. Higher successful rate was found in the second trimester than the third trimester in obtaining the standard views (P < 0.05). Finally, 73 (1.50%) among the 4882 cases were diagnosed as CHD. Fifty of them were diagnosed prenatally (24 cases in the second trimester and 26 cases in the third trimester) and 23 were missed and 1 misdiagnosed by prenatal ultrasound. Eighteen cases were found with extracardiac malformations. Autopsy was performed in 19 CHD which diagnosed prenatally, and all autopsy reports were consistent with ultrasound foundings. Twelve babies received postnatal echocardiography among which 11 were unanimous, and 1 baby diagnosed as tricuspid insufficiency prenatally was confirmed normal after birth. Abnormal karyotype was found in 7 out of the 23 who had karyotyping performed. Altogether, 28 cases were diagnosed by four chamber view only and 50 cases by combining other views, giving the sensitivity, specificity, false negative rate and false positive rate of 69% (50/73), 99.98% (4808/4809), 0.48% (23/4831) and 2% (1/51), respectively. CONCLUSION The "Guidelines for performing fetal cardiac scan" is practical and easy to abide by. The optimal time for fetal cardiac examination is at 18 approximately 27 weeks of gestation. Four-chamber view together with the outflow tracts and three-vessel views examination can detect 69% of CHD in utero.

Abstract
OBJECTIVE To explore the genetic prenatal diagnosis method for achondroplasia (ACH). METHODS During May to November 2007, three ACH pedigrees were diagnosed at the Prenatal Diagnosis Center, Department of Obstetrics and Gynecology, Affiliated Drum Tower Hospital of Medical College, Nanjing University. In family 1, there was a 6-month-old male ACH infant. In family 2, the expectant mother, with 18 weeks of pregnancy, was an ACH patient. Amniocentesis was performed for prenatal diagnosis. The fetus of family 3 was diagnosed as ACH by ultrasound examination on the 39th week of gestation. Umbilical cord blood of this fetus was collected for examination. Totally, three methods, restriction enzyme (SfcI and MspI) digestion analysis, denaturing high performance liquid chromatography (DHPLC) and sequencing analysis were performed simultaneously to detect the pathogenic mutation of fibroblastic growth factor receptor 3 (FGFR3) for the three ACH families. RESULTS (1) The DHPLC detection: heteroduplex was detected in the patient of family 1; both the patient and the fetus of family 2 showed heteroduplex results; the result of the fetus of family 3 was also heteroduplex. (2) The enzyme digestion analysis for the PCR products of 10 exon of FGFR3: after SfcI digestion, the PCR products of patients and the fetus of family 1 and 2 showed not only the band of 247 bp, but also bands of 162 bp and 85 bp. But their PCR products could not be digested by MspI, and it only showed the band of 247 bp. For the fetus of family 3, the PCR products could not be digested by SfcI, while after digestion by MspI, bands of 162 bp and 85 bp were shown up. The PCR products of the normal control could be digested by neither SfcI nor MspI. (3) The sequencing results: the heterozygote mutation of 1138 G-->A was confirmed in the patient of family 1. The pregnant woman and her fetus in family 2 showed the same result. The heterozygote mutation of G-->C was confirmed in the fetus of family 3. The site of 1138 was G homozygote in the normal control. The three detection results of the fetus in family 2 were the same as that of the mother, which means that the fetus inherited the same pathogenic mutation from his or her mother. CONCLUSIONS Both DHPLC and restriction enzyme digestion analysis could detect the mutation of FGFR3 gene, but DHPLC is more rapid, convenient and sensitive. So DHPLC can be applied to genetic diagnosis and prenatal diagnosis for ACH patients.

Abstract
OBJECTIVE To study the applicability of MultiCalc software to prenatal screening of Down's syndrome in Jiangsu province, China. METHODS The gestational age-specific median of maternal serum marker was calculated by means of regression method. Regression functions for adjustment of Multiple of the Median (MoM) by weight were established for our own population. RESULTS Before the adjustment by weight, the average level of alpha fetal protein(AFP) was 16% higher and the free beta-human chorionic gonadotrophin (beta-hCG) was 14% higher than those of the Caucasian in MultiCalc software respectively. But when the AFP and free beta-hCG results were converted to weight-adjusted MoM levels, the values were 0.99 and 1.02 respectively. The median of MoM of AFP and the free beta-hCG were 1.00 through the regression model of gestational age and weight adjustment. CONCLUSION There was no difference of average weight-adjusted MoM levels between the Jiangsu population and the Caucasian, and the MultiCalc software was applicable to maternal serum screening for Down's syndrome of Jiangsu.
