Objective To explore the dynamic changes of D-dimers during pregnancy and early puerperium (within 3 days postpartum). Methods A retrospective study was performed among 8 367 healthy women who had term singleton delivery in Women′s Hospital, School of Medicine, Zhejiang University from January 2007 to December 2014. D-dimers concentrations during pregnancy and early puerprium of all the cases were collected. Data of 21 065 D-dimers tests were assigned to 5 groups according to the time of sampling, including early pregnancy (≤12 gestation weeks), middle pregnancy (12-28 gestation weeks), late pregnancy (>28 gestation weeks), 1 postpartum (within 48 hours postpartum) and 2 postpartum (48-72 hours postpartum). The D-dimers concentrations in different groups were compared. The effect of delivery mode on D-dimers of early pureperium was analyzed. The correlation between D-dimers and the thromboembolic disease was also explored. In this study, Student′s t-test and Wilcoxon rank sum test were used for statistical analysis. D-dimers concentration≤0.5 mg/L was used as the normal range. Results (1) D-dimers concentrations during pregnancy were higher than the non-pregnant women (P<0.01), but there was no statistical difference between early pregnancy and late pregnancy (P=0.820). D-dimers concentration in the 1 postpartum group was higher than that of early pregnancy group or late pregnancy group (P<0.01). But in the 2 postpartum group, it was lower than early pregnancy, late pregnancy and 1 postpartum groups. (2)D-dimers in cesarean section cases was significantly higher than in vaginal delivery cases in each period of pregnancy and early pueprium.(3)The 95%CI of D-dimers in early pregnancy, late pregnancy, 48 hours after vaginal delivery, 48-72 hours after vaginal delivery, ≤48 hours after cesarean section, 48-72 hours after cesarean section were 0.58-8.28, 0.47-11.52, 1.04-9.59, 0.87-5.22, 1.07-11.58 and 1.00-6.23 mg/L, respectively.(4)In 6 cases with thromboembolic disease, D-dimers was 6.89-19.89 mg/L, with the mean value of 13.66 mg/L. It was significantly higher than normal range. In 3 cases, all after cesarean section, with lower extremity vein thrombosis within 48 hours postpartum, the D-dimers concentrations, 9.77, 8.65 and 6.89 mg/L respectively, were in the 95%CI of the study population after cesarean section. Conclusions D-dimers concentration of 0.5 mg/L is not suitable for venous thromboembolism screening during pregnancy. D-dimers concentration in pregnancy and early puerprium is higher than non-pregnancy. It increases in the very early period postpartum and decreases with time. D-dimers should not be a routine screening test to exclude thromboembolic disease in pregnant women without high risk factors and clinical manifestation of thromboembolic disease.

Objective To investigate the risk factors and clinical manifestations of placental abruption, and to analyze the causes of missed diagnosis and misdiagnosis. Methods A retrospective analysis was conducted in 135584 women who delivered in Women′s Hospital, School of Medicine, Zhejiang University from January 2005 to December 2015. The diagnosis of placental abruption was made in 1212 cases. According to the consistency of prenatal and postnatal diagnosis, they were divided into 3 groups.(1) The diagnosis was consistent prenatally and postnatally in 715 cases(58.99%,715/1212) as the diagnosis group.(2)In 312 cases (25.74%,312/1212), the diagnosis was made after birth as the missed diagnosis group.(3)In 185 cases (15.26%,185/1212), the diagnosis was made prenatally but excluded after birth as the misdiagnosis group. The disease classification was made, and the risk factors, clinical manifestations, lab results, the time of termination and perinatal outcomes were recorded in the 3 groups. The reasons of missed diagnosis and misdiagnosis were analyzed. Results (1) In the 1212 cases, the diagnosis of placental abruption was confirmed in 1027 cases, with the incidence of 0.76%(1027/135584). The rate of missed diagnosis was 30.38%(312/1027), and the rate of misdiagnosis was 0.14%(185/134557). (2) There were significant differences in the degree of placental abruption among the 3 groups (P＜0.05). (3)Significant differences were found among the 3 groups regarding the ratio of hypertensive disorders, trauma, induced labor and advanced maternal age (all P＜0.05). (4) There were statistically significant differences among the 3 groups regarding the incidence of vaginal bleeding, persistent abdominal pain and uterine tenderness, bloody amniotic fluid, increased uterine tension and stillbirth (all P＜0.05). (5) There was no significant difference in the rate of abnormal fetal heart rate mornitoring among the 3 groups (P=0.22). The differences were statistically significant among the 3 groups when regarding the incidence of abnormal ultrasound finding and abnormal blood coagulation (P＜0.01), with the highest incidence of abnormal ultrasound in the diagnosis group (68.1%) and the highest incidence of abnormal coagulation in the misdiagnosis group (24.9%). (6)There was statistically significant difference among the 3 groups when comparing the ratio of termination of pregnancy within 24 hours (P=0.01). (7) There were statistically significant differences among the 3 groups when the ratios of postpartum hemorrhage, DIC, neonatal asphyxia and perinatal death were compared (all P＜0.05). The highest incidence of postpartum hemorrhage was in the diagnosis group (17.9%) and the lowest was in the misdiagnosis group (5.4%). The highest incidence of DIC was in the diagnosis group (3.9%) and the lowest was in the misdiagnosis group (0). The highest incidence of neonatal asphyxia was in the diagnosis group (30.6%) and the lowest was in the misdiagnosis group (7.6%). And for perinatal death, the highest incidence was in the diagnosis group (12.6%), the lowest was in the misdiagnosis group (2.2%). Conclusions Placental abruption could be misdiagnosed when depending on risk factors, such as trauma. And it could be missed diagnosis during the induction of labor. Uterine contraction, abnormal fetal heart rate mornitoring, abnormal ultrasound and abnormal coagulation function are important in the diagnosis of placental abruption.

Objective To compare the effects of neutral posture training (NPT) and gas resistance training on balance and motor func-tion in stroke patients. Methods From June, 2014 to February, 2016, 44 hemiplegic patients were randomly divided into control group (n=22) and experimental group (n=22). The control group received conventional decubitus trunk muscle training and sitting gas resistance train-ing. The experimental group received NPT. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Fugl-Meyer Assessment-Lower Extremities (FMA-LE), and Berg Balance Scale (BBS) before and after training. Results There was no significant differ-ence in the scores of FMA-UE, FMA-LE and BBS between two groups (t<0.962, P>0.05). The scores significantly increased after training in both groups (t>12.248, P<0.001), and were higher in the experimental group than in the control group (t>1.972, P<0.05). Conclusion The NPT could improve the motor and balance function of stroke patients, rather than gas resistance training.
