OBJECTIVE: To analyze the result of prenatal diagnosis and outcome of pregnancy for fetuses with rare autosomal trisomies (RATs) suggested by non-invasive prenatal testing (NIPT). METHODS: A total of 69 608 pregnant women who underwent NIPT at Genetics and Prenatal Diagnosis Center of the First Affiliated Hospital of Zhengzhou University from January 2016 to December 2020 were selected as study subjects. The result of prenatal diagnosis and outcome of pregnancy for those with a high risk for RATs were retrospectively analyzed. RESULTS: Among the 69 608 pregnant women, the positive rate of NIPT for high-risk RATs was 0.23% (161/69 608), with trisomy 7 (17.4%, 28/161) and trisomy 8 (12.4%, 20/161) being the most common, and trisomy 17 (0.6%, 1/161) being the rarest. For 98 women who had accepted invasive prenatal diagnosis, 12 fetal chromosomal abnormalities were confirmed, and in 5 cases the results were consistent with those of NIPT, which yielded a positive predictive value of 5.26%. Among the 161 women with a high risk for RATs, 153 (95%) were successfully followed up. 139 fetuses were ultimately born, with only one being clinically abnormal. CONCLUSION Most women with a high risk for RATs by NIPT have good pregnancy outcomes. Invasive prenatal diagnosis or serial ultrasonography to monitor fetal growth, instead of direct termination of pregnancy, is recommended.

Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disease that affects multiple organs and systems. It is more common in women of childbearing age. Compared with the general population, pregnant women with SLE are at a significantly increased risk of adverse perinatal outcomes such as preterm birth and intrauterine growth restriction. In addition, the offspring of SLE patients may also be adversely affected by in utero exposure to maternal autoantibodies, cytokines, and drugs. This article summarizes the long-term developmental outcomes of offspring of pregnant women with SLE in terms of the blood system, circulatory system, nervous system, and immune system.

OBJECTIVE: To evaluate the efficacy of Chinese plaster containing rhubarb and mirabilite on surgical site infection (SSI) in patients with cesarean delivery (CD) by performing a randomized controlled trial. METHODS: This randomized controlled trial included 560 patients with CD due to fetal head descent enrolled at a tertiary teaching center between December 31, 2018 and October 31, 2021. Eligible patients were randomly assigned to a Chinese medicine (CM) group (280 cases) or a placebo group (280 cases) by a random number table, and were treated with CM plaster (made by rhubarb and mirabilite) or a placebo plaster, respectively. Both courses of treatment lasted from the day 1 of CD, followed day 2 until discharge. The primary outcome was the total number of patients with superficial, deep and organ/space SSI. The secondary outcome was duration of postoperative hospital stay, antibiotic intake, and unplanned readmission or reoperation due to SSI. All reported efficacy and safety outcomes were confirmed by a central adjudication committee that was unaware of the study-group assignments. RESULTS: During the recovery process after CD, the rates of localized swelling, redness and heat were significantly lower in the CM group than in the placebo group [7.55% (20/265) vs. 17.21% (47/274), P<0.01]. The durution of postoperative antibiotic intake was shorter in the CM group than in the placebo group (P<0.01). The duration of postoperative hospital stay was significantly shorter in the CM group than in the placebo group (5.49 ± 2.68 days vs. 8.96 ± 2.35 days, P<0.01). The rate of postoperative C-reactive protein elevation (≽100 mg/L) was lower in the CM group than in the placebo group [27.6% (73/265) vs. 43.8% (120/274), P<0.01]. However, there was no difference in purulent drainage rate from incision and superficial opening of incision between the two groups. No intestinal reactions and skin allergies were found in the CM group. CONCLUSIONS CM plaster containing rhubarb and mirabilite had an effect on SSI. It is safe for mothers and imposes lower economic and mental burdens on patients undergoing CD. (Registration No. ChiCTR2100054626).

Mosaic embryos contain two or more genetically distinct cell lines, which can be detected by pre-implantation genetic testing for aneuploidy. At present, it has been reported that mosaic embryo transfer can lead to healthy live births. In order to prevent severe adverse pregnancy outcomes, such as implantation failure, abortion, congenital malformation and neonatal death after implantation of mosaic embryos, it is critical to carry out genetic counseling, prenatal diagnosis and pregnancy supervision for mosaic embryo transfer. This article reviews the selection of mosaic embryos, the pregnancy outcomes of mosaic embryo transfer, and the safety of offspring, in order to provide references for the clinical practice of mosaic embryo transfer.

Objective: To retrospectively analyze the clinical data of different types of selective intrauterine growth restriction (sIUGR) pregnant women under expectant management, including the natural evolution, typing conversion and perinatal outcomes. Methods: The clinical data of 153 pregnant women with sIUGR under expected treatment in Women's Hospital, Zhejiang University School of Medicine from January 2014 to December 2018 were collected. Maternal characteristics including maternal age, gravidity, parity, method of conception, pregnancy complication, gestational age at delivery, indication for delivery, birth weight, the rate of intrauterine and neonatal death and neonatal outcomes were recorded. Pregnant women with sIUGR were divided into three types according to end-diastolic umbilical artery flow Doppler ultrasonography, and the differences of typing conversion and perinatal outcomes of sIUGR pregnant women based on the first diagnosis were compared. Results: (1) Clinical characteristics and pregnancy outcomes: among 153 pregnant women with sIUGR, 100 cases (65.3%) were diagnosed with type Ⅰ, 35 cases (22.9%) with type Ⅱ, and 18 cases (11.8%) with type Ⅲ. There were no significant differences in age, conception mode, pregnancy complications, first diagnosis gestational age, characteristics of umbilical cord insertion, delivery indications, fetal intrauterine mortality and neonatal mortality among three types of sIUGR pregnant women (all P>0.05). The average gestational age at delivery of type Ⅰ sIUGR was (33.5±1.9) weeks, which was significantly later than those of type Ⅱ and Ⅲ [(31.3±1.8), (31.2±1.1) weeks, P<0.001]. The percentage disordance in estimated fetal weight (EFW) of type Ⅰ sIUGR was significantly lower than those of type Ⅱ and type Ⅲ (P<0.001). The incidence rate of neonatal intensive care unit (NICU) admission, cerebral leukomalacia and respiratory complications of both fetus and necrotizing enterocolitis of large fetus in type Ⅰ were significantly lower than those in type Ⅱ and type Ⅲ (all P<0.05). (2) Typing conversion: in 100 cases of type Ⅰ sIUGR, 18 cases progressed to type Ⅱ and 10 cases progressed to type Ⅲ. Compared with 72 stable type Ⅰ sIUGR, those with progressed type Ⅰ sIUGR had higher incidence of NICU admission and lung disease in both fetuses, and cerebral leukomalacia and necrotizing enterocolitis in large fetus (all P<0.05). The proportion of inconsistent cord insertion was significantly higher in those type Ⅰ progressed to type Ⅲ (6/10) than in those with stable type Ⅰ (19.4%, 14/72) and type Ⅰ progressed to type Ⅱ sIUGR [0 (0/18), P=0.001]. Four cases of type Ⅱ sIUGR reversed to type Ⅰ and 6 cases reversed to type Ⅲ. Compared with type Ⅱ reversed to type Ⅰ sIUGR, those stable type Ⅱ and type Ⅱ reversed to type Ⅲ sIUGR had a higher incidence of NICU admission in large fetus (P<0.05). Two cases of type Ⅲ sIUGR reversed to type Ⅰ and 6 cases progressed to type Ⅱ. There were no significant differences in fetal serious complications in type Ⅲ sIUGR with or without doppler changes (all P>0.05). Conclusions: The different types of sIUGR could convert to each other. The frequency of ultrasound examinations should be increased for patients with the type Ⅰ sIUGR, especially when the percentage discordance in EFW is substantial or with discordant cord insersion.

Objective: To explore the effects of pregnancy complicated with moyamoya disease on maternal and fetal outcomes. Methods: The general clinical data and maternal and fetal outcomes of 20 pregnancies of 15 patients with moyamoya disease admitted to the First Affiliated Hospital of Zhengzhou University from January 2012 to October 2022 were retrospectively analyzed. Results: (1) General information: among the 20 pregnancies of 15 clearly diagnosed pregnant women complicated with moyamoya disease, 12 were diagnosed before pregnancy (60%, 12/20), 3 were diagnosed during pregnancy (15%, 3/20), and 5 were diagnosed during puerperal period (25%, 5/20). There were 7 cases of primipara (35%, 7/20) and 13 cases of multipara (65%, 13/20). (2) Pregnancy complications and maternal and infant outcomes: among the 20 pregnancies of 15 pregnant women with moyamoya disease, there were 9 pregnancy complications (45%, 9/20), including 5 gestational hypertension (25%, 5/20), 2 severe pre-eclampsia (10%, 2/20), 1 hyperlipidemia and 1 gestational diabetes mellitus (5%, 1/20). There were 2 case of drug abortion in the first trimester, 3 cases of labor induction in the second trimester, and 15 cases of delivery during the third trimester. All the 15 deliveries were cesarean section, of which 11 (11/15) were cesarean sections with medical indications, and 4 (4/15) were cesarean sections caused by personal factors. General anesthesia was used in 5 cases (5/15), epidural block anesthesia in 7 cases (7/15), and combined spinal and epidural anesthesia in 3 cases (3/15). The median gestational age of 15 neonates was 37.2 weeks (34.0 to 40.8 weeks), with 10 cases (10/15) were full-term infants, and 5 (5/15) were preterm infants (3 of which were associated with hypertensive disorder complicating pregnancy). The birth weight of 15 neonates was (2 853±454) g. Four neonates were admitted to neonatal intensive care unit (NICU), of which 3 cases were admitted to NICU due to premature delivery and 1 case was admitted to NICU due to neonatal jaundice. There was no neonatal asphyxia or death. All neonates were followed up from 4 months to 6 years after birth, and all grew well. (3) Neurological symptoms during pregnancy: 8 cases (40%, 8/20) had neurological symptoms during pregnancy, and 6 cases (30%, 6/20) had hemorrhagic symptoms, of which 3 cases occurred during the puerperal period (3/6). There were 2 cases of ischemic symptoms (10%, 2/20), all of which occurred during the puerperal period (2/2). (4) Analysis of factors related to the occurrence of cerebral hemorrhage: the incidence of cerebral hemorrhage in patients with moyamoya disease diagnosed before pregnancy was significantly lower than that in those without a clear diagnosis, and the incidence of cerebral hemorrhage in women with moyamoya disease was lower than that in primipara (all P<0.01). The incidence of cerebral hemorrhage in moyamoya patients without hypertensive disorder complicating pregrancy was lower than that in patients with hypertensive disorder complicating pregrancy, but the difference was not statistically significant (P>0.05). Conclusions: Pregnancy combined with moyamoya disease has adverse effects on maternal and infant outcomes, and the incidence of pregnancy complications increases. Cerebral hemorrhage occurres in prenatal and puperium, while cerebral ischemia occurres mainly in puperium.

Objective: To explore the key points for preventing and reducing severe pre-eclampsia (SPE) and its severe complications in the tertiary medical referral system of a second-tier city by analyzing the clinical characteristics of SPE. Methods: The clinical data of 341 patients with SPE who terminated pregnancy in Women and Children's Hospital, School of Medicine, Xiamen University, from January 1, 2020 to December 31, 2022 were retrospectively analyzed, and the pre-eclampsia (PE) risk factors, clinical characteristics and severe complications of SPE between the patients referred from primary hospitals (referral group) and the patients received regular prenatal care in the tertiary referral center (central group) were compared, as well as the influence of the referral timing on the maternal and perinatal outcomes. Results: Among the 341 cases of SPE, 92 cases were in the referral group and 249 cases were in the central group. (1) Analysis of PE risk factors: there was no statistical difference in the proportion of risk factors of PE between these two groups [75.0% (69/92) vs 71.9% (179/249); χ²=0.328, P=0.567]. (2) Analysis of clinical features: the gestational ages at the PE early warning factors onset, at the PE first symptom onset and at SPE diagnosed, pregnancy terminated and onset of SPE severe complications in the referral group were significantly earlier than those in the central group (all P<0.05), the proportions of terminating pregnancy before 32 weeks of gestation, between 32 and 34 weeks of gestation, intensive care unit (ICU), neonatal ICU hospitalization and fetal growth restriction in single pregnancies were higher than those in the central group, while the live birth rate was lower than that in the central group (all P<0.05). (3) Analysis of SPE severe complications: the rates of SPE severe complications in the referral group was higher than that in the central group [28.3% (26/92) vs 13.7% (34/249); χ²=9.885, P=0.002]. Among them, the rates of placental abruption [7.6% (7/92) vs 2.8% (7/249); χ²=3.927, P=0.048] and still birth [6.5% (6/92) vs 0.4% (1/249); χ²=9.656, P=0.002] in the referral group were significantly higher than those in the central group. (4) Analysis of referral timings: the timings included referral after onset of SPE severe complications (9.8%, 9/92), referral after SPE diagnosed (63.0%, 58/92), referral after detection of SPE early warning signs (20.7%, 19/92) and referral after detection of PE risk factors (6.5%, 6/92). The gestational ages at SPE diagnosed and pregnancy terminated in group of referral after onset of SPE severe complications and group of referral after SPE diagnosed were significantly earlier than those in group of referral after detection of PE early warning signs and group of referral after detection of PE risk factors (P<0.05). The earlier the referral, the higher the live birth rates (P<0.05). Conclusions: The tertiary referral center of the second-tier city plays an important role in reducing the maternal and perinatal damage of PE. The timing of referral in primary medical institutions is the key point of reducing the occurrence of SPE severe complications and maternal, perinatal damage of PE. It is necessary for medical institutions of all levels in all regions to improve the ability of early identification and early intervention for PE, to enhance the awareness of SPE and its severe complications prevention and control. Primary medical institutions should especially pay attention to raise the consciousness of PE risk factors and early warning signs, and to improve the ability of PE risk factors and early warning signs screening.
