Blocking lactate regulation of the Grhl2/SLC31A1 axis inhibits trophoblast cuproptosis and preeclampsia development.

PURPOSE: Abnormal cell death due to superficial trophoblast dysfunction caused by placental hypoxia plays a vital role in the development of preeclampsia (PE). Lactic acid stimulates gene transcription in chromatin through lactate modification of histone lysine. Nevertheless, the content and function of lactate in PE development remains largely unclear. METHODS: The contents of lactic acid and copper in 30 PE and 30 normal placentas were determined by kit colorimetry. Real-time quantitative fluorescent PCR (qRT-PCR) and Western blot were used to detect the expression of SLC31A1 in cells and tissues. Cell proliferation, apoptosis, and invasion were detected by cell counting kit 8 (CCK-8), MTS assay, colony formation assay, and Transwell assay. The transcriptional regulation between Grhl2 and SLC31A was verified by the luciferase reporter gene method and ChIP. The H3K18la modification level was detected by ChIP-PCR. RESULTS: Herein, we detected increased lactic acid levels in the PE placental tissue, which inhibit the proliferation and invasion of trophoblasts. Interestingly, lactic acid increases intracellular copper content by enhancing the expression of SLC31A1, a key protein of copper ion transporters. Lentivirus knockdown of SLC31A1 blocked the lactate-induced proliferation and invasion of trophoblasts by inhibiting cell cuproptosis. Mechanically, we identified that Grhl2 mediated SLC31A1 expression through transcription and participated in SLC31A1-inhibited proliferation, invasion, and cuproptosis of trophoblasts. Furthermore, the high lactate content increased Grhl2 expression by enhancing lactate modification of histone H3K18 in the Grhl2 promoter region. CONCLUSIONS: Blocking the lactate-regulated Grhl2/SLC31A1 axis and trophoblastic cuproptosis may be a potential approach to prevent and treat PE.

Effect of Targeted Care plus Exercise Intervention on Blood Glucose Levels and Maternal and Newborn Outcomes in Patients with Gestational Diabetes Mellitus.

Objective: To evaluate the effect of targeted care plus exercise intervention on blood glucose levels and maternal and newborn outcomes in patients with gestational diabetes mellitus (GDM). Methods: A total of 96 patients with GDM admitted to our hospital between March 2018 and January 2020 were recruited and assigned to receive either routine nursing (routine group) or targeted care plus exercise intervention (study group) via random method, with 48 patients in each group. Outcome measures included blood glucose, immune function, maternal and newborn outcome, and nursing satisfaction. Results: The patients in the study group had significantly lower amniotic fluid index (AFI), weight at delivery, body mass index (BMI), and weight gain during pregnancy than patients in the routine group (P < 0.05). There was no statistically significant difference in blood glucose between the two groups of patients before the intervention (P > 0.05). Targeted care plus exercise intervention resulted in significantly lower levels of fasting blood glucose (FBG), 2 h postprandial blood glucose (2hPBG), and blood glucose before bed versus routine care (P < 0.05). The patients with targeted care plus exercise intervention had higher immunoglobulin G (IgG) and IgM levels; higher CD3+, CD4+, and CD8+ levels; and lower lgA levels versus those with routine care (P < 0.05). Targeted care plus exercise intervention was associated with a lower incidence of negative pregnancy outcomes and a higher satisfaction versus routine care (P < 0.05). Conclusion: Targeted treatment plus exercise intervention efficiently controls blood glucose levels in GDM patients, improves immunological function, lowers the risk of pregnancy problems, improves pregnancy outcomes, and promotes patient satisfaction, indicating a high potential for therapeutic development. Targeted treatment combined with exercise intervention is encouraged following effective pharmacological interventions to facilitate recovery.

Effect of Predictive Nursing Combined with Early Drinking Water Therapy on Patients with Urinary Retention after Vaginal Delivery.

The aim of this study is to analyze the effect of predictive nursing combined with early drinking water therapy on patients with urinary retention after vaginal delivery. A total of 600 women who gave birth in our hospital from July 2019 to July 2020 were selected as the research objects. A double-blind method was adopted to divide them into a control group and observation group, 300 cases in each group. In the control group, routine nursing was given. In the observation group, (1) predictive nursing measures were used before surgery. (2) The postoperative observation group used early drinking water therapy; the incidence of urinary retention, the effective rate of urination, postpartum haemorrhage, and the treatment of urinary retention were compared between the two groups. In the observation group, the number of urinary retention was 17, and the incidence of urinary retention was 5.67%. The urination efficiency of the observation group was 98.33%; the urination efficiency of the control group was 86.33%; comparison results showed that P < 0.05. The 24 h postpartum haemorrhage of the observation group was 1.33%; the 24 h postpartum haemorrhage of the control group was 2.66%. Uroschesis therapy was performed in 17 patients in the observation group and 44 patients in the control group.. The observation group had an 88.24 percent treatment rate, while the control group had a 72.73 percent treatment rate. P < 0.05 indicated that the difference was statistically significant.

Effect of overall nursing combined with acupressure in preventing postpartum urinary retention.

OBJECTIVES: This study investigated the effects of overall nursing care combined with acupressure in preventing postpartum urinary retention. METHODS: A total of 200 parturients with vaginal delivery in our hospital from March to October 2019 were enrolled and randomized to a control group and an observation group with 100 cases each. The control group received conventional nursing, while the observation group was also given "overall" nursing combined with acupressure. The two groups were compared in the incidence of urinary retention, time to the first urination, first urine volume, residual urine volume, pelvic floor muscle fiber contraction time, satisfaction, and treatment efficiency. RESULTS: The two groups presented no significant difference in general information (P>0.05). Compared to the control group, the observation group showed a lower incidence of urinary retention and experienced an earlier time to first urination (both P<0.001). A significantly smaller residual urine volume was observed in the observation group as compared to controls at 4 h and 12 h after delivery (P<0.05). The observation group outperformed the control group in terms of pelvic floor muscle fiber contraction duration (P<0.001). Moreover, the observation group showed a treatment efficiency and nursing satisfaction superior to the control group (P<0.05). CONCLUSIONS: Overall nursing care combined with acupressure can exert strong positive effects on the incidence of postpartum urinary retention, time to the first urination, and residual urine volume in parturients with vaginal delivery and improve their satisfaction.
