OBJECTIVE: To investigate the perinatal outcome and risk factors of precipitate labor in term primipara. METHODS: A total of 6951 full-term singleton primiparas with cephalic vaginal delivery in Women's Hospital, Zhejiang University School of Medicine from January 2020 to December 2020 were enrolled, among whom 381 cases of precipitate labor were classified as the precipitate labor group and 762 cases of normal labor were randomly selected as the control group. The perinatal outcomes of the two groups were compared, and the risk factors of precipitate labor were analyzed by multivariate logistic regression. RESULTS: The incidence of precipitate labor in full-term, singleton pregnancy and cephalic primiparas was 5.48% (381/6951). The durations of the first and second stages of labor in the precipitate labor group were significantly shorter than that in the control group ( P<0.01); while there was no significant difference in the duration of the third stage of labor between the two groups ( P>0.05). Compared with the control group, the incidence of soft birth canal laceration in the precipitate labor group was increased ( P<0.01). However, there was no significant difference in postpartum hemorrhage and neonatal related perinatal outcomes between the two groups (all P>0.05). Multivariate logistic regression analysis showed that maternal height ( OR=1.038, 95% CI: 1.010-1.067, P<0.01), gestational age at delivery ( OR=0.716, 95% CI: 0.618-0.829, P<0.01), late miscarriage ( OR=1.986, 95% CI: 1.065-3.702, P<0.05), membrane rupture before labor ( OR=1.802, 95% CI: 1.350-2.406, P<0.01), labor induction by transcervical balloon ( OR=3.230, 95% CI: 2.027-5.147, P<0.01), labor induction by propess ( OR=2.332, 95% CI: 1.632-3.334, P<0.01) and labor induction by oxytocin ( OR=0.291, 95% CI: 0.219-0.386, P<0.01) were independently associated with precipitate labor. CONCLUSIONS The incidence of precipitate labor in full-term, singleton pregnancy was not low. Precipitate labor could lead to a significant increase in perineal laceration. Maternal height, history of late miscarriage, membrane rupture before labor and labor induction by transcervical balloon, labor induction by propess are risk factors, while labor induction by oxytocin and late gestational time of delivery are protective factors for precipitate labor in term primipara.

To systematically evaluate the efficacy and safety of Gongxuening Capsules in the treatment of abnormal vaginal bleeding after medical abortion. CNKI, Wanfang, SinoMed, VIP, PubMed, Cochrane Library and EMbase databases were retrieved to comprehensively collect the clinical randomized controlled trials(RCTs) of Gongxuening Capsules for treatment of abnormal vaginal bleeding after medical abortion from the establishment of the databases to October 10, 2020. Literature screening, data extraction and quality evaluation were conducted independently by two system reviewers according to the inclusion and exclusion criteria. Cochrane Handbook bias risk assessment tool was used for the literature methodology quality evaluation, RevMan 5.3 software was used for Meta-analysis, and the evidence quality of outcomes was evaluated by the evidence quality grading system(GRADE). A total of 16 RCTs were inclu-ded. The results of Meta-analysis showed that as compared with the western medicine treatment alone, the addition of Gongxuening Capsules to the western medicine treatment can reduce the amount of vaginal bleeding(RR=1.23, 95%CI[1.19, 1.27], P<0.000 01), shorten vaginal bleeding time(RR_(≤15 d number of people)=1.39, 95%CI[1.31, 1.48], P<0.000 01; MD_(number ofdays)=-1.20, 95%CI[-1.66,-0.74],P<0.000 01). However, there was no obvious advantage in abortion effect(RR=1.02, 95%CI[0.99, 1.06], P=0.14) and menstrual recovery(MD=-0.35, 95%CI[-0.96, 0.25], P=0.25). The results of GRADE showed that the grading level was low for vaginal bleeding volume and vaginal bleeding time, and extremely low for abortion effect and mens-trual recovery. In terms of safety, 16 studies reported adverse events. Only one study showed no adverse events and the rest showed transient nausea, vomiting, stomach burning, upper abdominal discomfort and other gastrointestinal symptoms. The results show that the addition of Gongxuening Capsules to the application of western medicine in treatment of drug abortion can reduce the amount of vaginal bleeding and shorten vaginal bleeding time, but the abortion effect and menstrual recovery have no obvious advantages. The use of Gongxuening Capsules helps to achieve less adverse reactions and higher safety. Due to the small sample size of the included studies and many methodological quality problems, no conclusions with clinical guidance value can be obtained. Large sample-zise, high-qua-lity randomized controlled trials are still needed for further verification.

OBJECTIVE: To investigate the clinical efficacy of oral medicine and sodium hyaluronate in prevention of intrauterine adhesions after artificial abortion.
 METHODS: A total of 572 patients with early pregnancy termination through artificial abortion, who experienced two or more times of abortion, were retrospectively analyzed. Patients were randomly and voluntarily divided into 4 groups: an artificial cycle group, a drospirenone and ethinylestradiol tablets group, a sodium hyaluronate group, and a control group. The thickness of the endometrium, return time of menses, and the status of intrauterine adhesions were observed.
 RESULTS: The thickness of the endometrium in the artificial period group was greater than that in the control group (P<0.001). It was less in the drospirenone and ethinylestradiol tablets group comparing with that in the control group (P<0.001). There was no significant difference in the thickness of the endometrium between the sodium hyaluronate group and the control group (P=0.717). Return time of menses in the artificial menstrual cycle group and the drospirenone and ethinylestradiol tablets group was shorter than that in the control group (P<0.001). There was no significant difference in return time of menses between the sodium hyaluronate group and the control group (P=0.813). The incidence of intrauterine adhesions could be reduced by the 3 preventive measures (All P<0.01).
 CONCLUSION Drugs for artificial cycle and drospirenone and ethinylestradiol tablets medication immediately after artificial abortion can effectively promote endometrial repair and reduce the incidence of intrauterine adhesions. However, for the patients with poor compliance, drospirenoneand ethinylestradiol tablets are the first choice for prevention of intrauterine adhesion.

BACKGROUNDThe rate of cesarean delivery has significantly increased in China in the last decade. Women with prior cesarean history tend to have a higher risk of uterine rupture during termination of the pregnancy in mid-trimester than those without such a history. The aim of our study was to evaluate the influences of the potential risk factors on uterine rupture in women with prior cesarean.

METHODSWe conducted this retrospective study of women with prior cesarean section, who underwent mid-trimester pregnancy termination between January 2006 and December 2013 in Peking Union Medical College Hospital. The protocol was oral administration of mifepristone and misoprostol for the patients with the gestational ages below 16 weeks or intra-amniotic injection of ethacridine lactate (EL) for those with at least 16 weeks of gestational ages. The thickness of the lower uterine segment (LUS) was measured before the termination of pregnancy. Logistic regression was used to study the risk factors of uterine rupture.

RESULTSThe total rate of successful abortion was 93.9% (62/66). Four patients failed in induction, and one of them received curettage, whereas the other three experienced uterine rupture (4.5%). The successful rates of abortion were 85.7% (30/35) for women treated with mifepristone-misoprostol and 86.1% (31/36) for those treated with EL. There was a significant difference in the mean LUS thickness between the uterine rupture group (3.0 ± 2.0 mm) and the nonrupture group (7.0 ± 3.0 mm) (P < 0.05). The LUS thickness of <3 mm was associated with uterine rupture during mid-trimester pregnancy termination in women with prior cesarean (odds ratio, 94.0; 95% confidence interval 4.2-2106.1) after adjusted maternal age, gestational age, interdelivery interval and prior cesarean section. Severe bleeding that required transfusion occurred in one case (1.5%).

CONCLUSIONSBoth the mifepristone-misoprostol and the EL regimens were effective and safe for the termination of mid-trimester pregnancy in women with prior cesarean. A thinner LUS is associated with a relatively high risk of uterine rupture.

OBJECTIVETo evaluate the associations between birth order, maternal abortion and mode of delivery and childhood acute leukemia risk.

METHODMultiple electronic databases were searched to identify relevant studies up to March 2013 using the search terms "childhood leukemia", "acute lymphoblastic leukemia", "acute myeloid leukemia","birth order", "abortion", "miscarriage", "cesarean", "birth characteristics" and "prenatal risk factor". Data from cohort and case-control studies were analyzed using the Stata software.

RESULTTwenty-three studies were included in this meta-analysis according to the selection criteria. No significant associations were identified for birth order and mode of delivery (birth order = 2: OR = 0.97, 95%CI: 0.89-1.05; birth order = 3: OR = 1.00, 95%CI: 0.91-1.11; birth order ≥ 4: OR = 1.02, 95%CI: 0.87-1.20; mode of delivery: OR = 1.05, 95%CI: 0.96-1.15). However, there was a significant association between maternal abortion and childhood acute leukemia risk (spontaneous abortion: OR = 1.21, 95%CI: 1.05-1.41; induced abortion: OR = 1.23, 95%CI: 1.07-1.43). Furthermore, the stratified analysis by disease subtypes showed that spontaneous and induced abortions were significantly associated with the risks of childhood acute myeloid leukemia (OR = 1.71, 95%CI: 1.09-2.70) and acute lymphoblastic leukemia (OR = 1.23, 95%CI: 1.05-1.42), respectively.

CONCLUSIONThis meta-analysis revealed that maternal abortion might contribute to the childhood acute leukemia risk.

Antiphospholipid syndrome (APS) refers to a group of clinical symptoms and signs caused by antiphospholipid antibody (aPLA). We reported a rare case of poor outcome of a pregnant woman with APS. The pregnant woman had APS, hemolytic anemia, elevated liver function and low platelet count (HELLP) syndrome, and eclampsia and had a poor outcome from a second pregnancy. She was treated with antispasmodics, sedatives, and anti-hypertensive agents, along with anticoagulant therapy and infusion of immunoglobulin. APS during pregnancy often makes pregnancy even more complex and risky. Obstetricians should carry out anticoagulation treatment throughout the perinatal period.
