Background: Premature birth (PTB) is a major cause of neonatal mortality and has enduring consequences. LIM Homeobox 1 (LHX1) is vital in embryonic organogenesis, while Inositol-Requiring Enzyme 1 (IRE-1) regulates endoplasmic reticulum stress (ERS). This study explores whether IRE-1 impacts PTB via LHX1 modulation. Methods: We analyzed LHX1 expression in placental samples from PTB patients and examined its impact on the viability, migration, invasion, and apoptosis of the human placental trophoblast cell line HTR8/Svneo, particularly when treated with the ERS inducer tunicamycin (TM). We also assessed the levels of ERS-related genes and autophagy activation in response to LHX1 deficiency. To gain mechanistic insights, we evaluated the ERS-mediated activation of the IRE-1/XBP1/CHOP signaling pathway in LHX1-silenced HTR8/Svneo cells. Additionally, we examined the transcriptional activation of IRE-1 and the binding of LHX1 to the IRE-1 promoter in HTR8/Svneo cells. We overexpressed IRE-1 in LHX1-silenced HTR8/Svneo cells to assess its effects on cell viability, migration, invasion, apoptosis, and autophagy. Finally, we induced LHX1 knockdown in mice through intraperitoneal injections of tunicamycin (TM) and Sh-LHX1 over a 24-h period to evaluate PTB symptoms. Results: We observed LHX1 overexpression in placental tissue from PTB cases and TM-induced HTR8/Svneo cells. LHX1 depletion enhanced cell viability, migration, and invasion while reducing autophagy and apoptosis. This reduction in LHX1 led to decreased levels of IRE-1, XBP1, CHOP, and other ERS-related genes, indicating LHX1's role in ERS induction and the activation of the IRE-1/XBP1/CHOP pathway. Mechanistically, LHX1 was found to bind to the IRE-1 promoter, inducing its transcriptional activation. Notably, overexpressing IRE-1 counteracted the impact of LHX1 depletion on trophoblast cell behavior, suggesting that LHX1 modulates IRE-1. In line with our in vitro studies, LHX1 knockdown ameliorated PTB symptoms in TM-treated mice. Conclusion: LHX1 contributes to the progression of PTB by regulating the IRE-1-XBP1-CHOP pathway.
Objective:To compare effects of Atosiban and Ritodrine in treatment of late abortion and threatened premature labor in twin pregnancy women.Methods:A prospective study was conducted on 80 twin pregnancy women with late abortion and threatened premature labor admitted to this hospital from August 2021 to August 2023.They were divided into control group and observation group according to the random number table method,40 cases in each group.The control group was treated with Ritodrine hydrochloride,while the observation group was treated with Atosiban.The excellent and good rate of uterine contraction inhibition,the prolonged pregnancy time,the levels of sex hormone indexes before and after the treatment,the incidence of adverse pregnancy outcomes,and the incidence of adverse reactions were compared between the two groups.Results:The excellent and good rate of uterine contraction inhibition in the observation group was 97.50%(39/40),which was higher than 70.00%(28/40)in the control group,and the difference was statistically significant(P<0.05).The prolonged pregnancy time in the observation group was longer than that in the control group,and the difference was statistically significant(P<0.05).After the treatment,the levels of estriol in the two groups were lower than those before the treatment,and that in the observation group was lower than that in the control group;the progesterone levels of the two groups were higher than those before the treatment,and that in the observation group was higher than that in the control group;and the differences were statistically significant(P<0.05).The incidence of adverse pregnancy outcomes such as cesarean section,premature delivery,abortion,stillbirth and neonatal asphyxia in the observation group was lower than that in the control group,and the difference was statistically significant(P<0.05).However,there was no significant difference in the incidence of adverse reactions between the two groups(P>0.05).Conclusions:Atosiban in the treatment of the twin pregnancy women with late abortion and threatened premature labor can improve the excellent and good rate of uterine contraction inhibition,prolong the pregnancy time,improve the levels of sex hormone indexes,and reduce the incidence of adverse pregnancy outcomes.Moreover,it is superior to Ritodrine treatment.
Objective:To investigate the correlation between inositol level and glycolipid metabolism in gravidas with gestational diabetes mellitus (GDM).Methods:A cross-sectional study was conducted on 80 GDM cases undergoing routine examination at Fujian Provincial Maternity and Children's Hospital from November 2018 to August 2019, who were selected as GDM groups. Another 50 women with uncomplicated pregnancies during the same period were selected as the control group. Blood and urine inositol level and serum glycolipid profiles were compared between the two groups, and their association was analyzed. Independent or paired-sample t test, Mann-Whitney test, Chi-square (or Fisher's exact) test, and Pearson correlation test were performed for statistical analysis. Results:The serum inositol concentration and high-density lipoprotein (HDL) cholesterol in the GDM group were significantly lower [322.1 ng/ml (279.1-364.1 ng/ml) vs 403.8 ng/ml (391.8-425.3 ng/ml), Z=-7.879; 1.8 mmol/L (1.5-2.0 mmol/L) vs 2.0 mmol/L (1.7-2.2 mmol/L), Z=-2.419; both P<0.05], while the concentration of urine inositol, lipoprotein-a (lipo-a), 0 h-, 1 h-, 2 h-oral glucose tolerance test (OGTT) glucose, fasting insulin, and glycosylated hemoglobin (HbA1c) were significantly higher when comparing to the control group [192.2 ng/ml (171.0-219.9 ng/ml) vs 143.8 ng/ml (121.1-158.6 ng/ml), Z=-6.834; 253.2 mg/L (65.0-349.0 mg/L) vs 148.5 mg/L(46.5-159.3 mg/L), Z=-0.187; 5.0 mmol/L (5.1-5.6 mmol/L) vs 4.4 mmol/L (4.2-4.6 mmol/L), Z=-5.547; 10.0 mmol/L (9.1-11.3 mmol/L) vs 7.8 mmol/L (7.0-8.4 mmol/L), Z=-6.987; 8.6 mmol/L(7.6-9.4 mmol/L) and 6.6 mmol/L (5.7-7.1 mmol/L), Z=-7.100; 18.2 mU/L(10.6-25.9 mU/L) vs 11.0 mU/L (6.3-12.7 mU/L), Z=-4.537; 5.4%(4.5%-5.5%) vs 5.1%(4.9%-5.4%), Z=-3.468; all P<0.05]. (2) Serum inositol concentration was negatively correlated with fasting insulin and 0 h-, 1 h-, 2 h- OGTT glucose level ( r=-0.386, -0.416, -0.350 and -0.407, respectively); urinary inositol concentration was positively correlated with 0 h-, 1 h-, 2 h-OGTT glucose levels ( r=0.402, 0.389 and 0.429, respectively) (all P<0.05). Conclusions:Serum inositol concentration was decreased, and urinary inositol excretion was increased in women with GDM. Measurement of changes in inositol levels during the second trimester may be helpful to assess the metabolic status of pregnant women.
Objectives To analyze the clinical characteristics and perinatal outcomes of umbilical cord vascular rupture, and to investigate the diagnosis and treatment strategies for reducing adverse perinatal outcomes. Methods Clinical data of patients with a singleton pregnancy with umbilical cord rupture who were admitted to Fujian Maternity and Child Health Hospital were collected. The incidence, related factors, clinical features and perinatal outcomes of umbilical cord rupture were retrospectively analyzed. Results There were eight cases of umbilical cord rupture (incidence rate: 1/8370). Among them, seven were secondary to umbilical cord insertion abnormality, and one may have been related to a relatively short umbilical cord and umbilical cord traction. There were eight cases of abnormal fetal heart rate, two of vaginal bleeding, five of bloody amniotic fluid, five of premature rupture of the membranes, and two of placental abruption. With regard to outcomes, 50% of patients had cesarean section, 12.5% had forceps delivery, and 50% had perinatal mortality. Conclusions Vaginal bleeding, amniotic fluid, fetal heart rate, and umbilical cord insertion should be closely monitored in pregnancy. When abnormal conditions occur, obstetricians should be aware of rupture of the umbilical vessels and terminate pregnancy as soon as possible, which could improve perinatal outcomes.
