ABSTRACT
Uterine fistula after cesarean section mainly occurs in developing countries.With the development of social economy,the incidence of uterine fistula in China is gradually decreasing.However,in recent years,the incidence of placenta previa–accreta is increasing and the intraoperative injury is increasing.We describe the most common uterine fistula after cesarean section to provide reference and basis for its diagnosis and treatment.
ABSTRACT
p53 gene plays an important role in apoptosis, which is necessary for successful invasion of trophoblast cells. The change from an arginine (Arg) to a proline (Pro) at codon 72 can influence the biological activity of p53, which predisposes to an increased risk of recurrent spontaneous abortion (RSA). In order to investigate the association between p53 polymorphism at codon 72 and RSA, we conducted this meta-analysis. Pubmed, Embase and Web of science were used to identify the eligible studies. Odds ratio (OR) with 95% confidence interval (CI) was used to evaluate the strength of the association. Six studies containing 937 cases of RSA and 830 controls were included, and there was one study deviated from Hardy-Weinberg equilibrium (HWE). There was a significant association between p53 polymorphism at codon 72 and RSA in recessive model (Pro/Pro vs. Pro/Arg+Arg/Arg; OR=1.60, 95% CI: 1.14-2.24) and co-dominant model (Pro/Pro vs. Arg/Arg; OR=1.47, 95% CI: 1.02-2.12) whether the study that was deviated from HWE was eliminated or not. A significant association was observed in allelic model (Pro vs. Arg; OR=1.28, 95% CI: 1.04-1.57) after exclusion of the study that was deviated from HWE. No association was noted in recessive model (Pro/Pro+Pro/Arg vs. Arg/Arg; OR=1.05, 95% CI: 0.86-1.30) and co-dominant model (Pro/Arg vs. Arg/Arg; OR=0.96, 95% CI: 0.77-1.19). Subgroup analysis by ethnicity also indicated a significant association between p53 polymorphism at codon 72 and RSA in Caucasian group. No heterogeneity and publication bias were found. Our meta-analysis implied that p53 polymorphism at codon 72 carries high maternal risk of RSA.

Severe liver dysfunction in pregnancy (SLDP) is rare but serious complications with high mortality rate. This study compared the effectiveness and safety of double-balloon catheter versus intra-amniotic injection of ethacridine lactate for the termination of second trimester pregnancy in patients with SLD. A total of 55 patients with indications of labor induction were enrolled and analyzed by retrospective control analysis method. Twenty-three cases adopted Cook double balloon dilation as Cook group, and 32 cases received intra-amniotic injection of ethacridine lactate as EL group. The primary outcome was evaluated by successful abortion rate and the difference in the induction-to-abortion interval. Secondary outcomes included liver function recovery and the frequency of adverse events. Both Cook and EL regimens were effective, with successful abortion rate of 87.0% and 93.8%, respectively (P=0.639). The induction-to-delivery interval was similar between Cook group and EL group (38.1±21.5 vs. 41.3±17.4, P=0.543). The liver disease status was more severe in Cook group than in EL group, but it did not show any significant difference after pregnancy termination between the two groups and the improvement rate also did not show any significant difference. Both treatments were safe and there was no significant difference in bleeding and cervical laceration adverse events between the two groups. Our study firstly compared double-balloon catheter and ethacridine lactate for the induction of labor in women with SLD during second trimester pregnancy.
