The relationship between renal function indicators and preeclampsia in the second trimester of pregnancy: a retrospective study.

Background: To investigate the relationship between serum renal function indicators and preeclampsia (PE) in pregnant women at second trimester of pregnancy, determine the optimal critical values of the above indicators, and further identify the independent risk factors of PE.

Methods: We assessed the renal function indicators in second trimesters of 137 pregnant women with PE and 137 normal pregnant women who delivered at Shijiazhuang Fourth Hospital between January 2020 to December 2022. Paired -tests, paired Mann-Whitney U tests, and Chi-square tests were used to evaluate differences of clinical data between the two groups.

A retrospective study of the correlation between high serum ferritin levels and the risk of gestational diabetes mellitus in midpregnant women.

Aims: Gestational diabetes mellitus (GDM) is any degree of glucose intolerance with onset or first detection during pregnancy, with an inconsistent association with serum ferritin (SF). We aimed to ascertain the relationship between SF and the risk of GDM in mid-pregnancy and provide evidence for implementing clinical individualized and reasonable iron supplementation regimens.

Methods: A retrospective study was conducted to investigate 1,052 pregnant women at 24-28 weeks of gestation who were examined in the obstetrics department of The Fourth Hospital of Shijiazhuang from January 2019 to December 2021.

Evaluation of alanine aminotransferase/aspartate aminotransferase ratio and high-density lipoprotein for predicting neonatal adverse outcomes associated with intrahepatic cholestasis of pregnancy.

Background: To determine the association between lipid metabolism and intrahepatic cholestasis of pregnancy (ICP), and explore the value of maternal alanine aminotransferase/aspartate aminotransferase (ALT/AST) and high-density lipoprotein (HDL) in predicting adverse neonatal outcomes in women with ICP.

Methods: A total of 147 pregnant women with ICP admitted to The Fourth Hospital of Shijiazhuang and 120 normal pregnant women in the same period were selected in this study. The Mann-Whitney U test and Chi-square tests were used to compare the differences in clinical data.

The discrepancy distribution of macrophage subsets in preeclampsia placenta with or without fetal growth restriction from a small cohort.

Objectives: To identify the effect of distribution characteristic of macrophages on placental function and angiogenesis in pregnancies with preeclampsia (PE) in presence of fetal growth restriction (FGR) or preeclampsia without FGR.

Material And Methods: The study tested the hypothesis that there was association between distribution characteristic of macrophage subsets (marked by CD68, CD163, respectively) and placental capillary development, leading to placental dysfunction in PE pregnancies with FGR (n = 36). Changes in placental parameters related with efficiency and angiogenesis and macrophage phenotypes (CD68 and CD163) were evaluated by immunohistochemistry.

The correlation between serum total bile acid and alanine aminotransferase of pregnant women and the disorders of neonatal hyperbilirubinemia-related amino acid metabolism.

Background: To explore the association between liver metabolism-related indicators in maternal serum and neonatal hyperbilirubinemia (NHB), and further investigate the predictive value of these indicators in NHB-related amino acid metabolism disorders.

Methods: 51 NHB and 182 No-NHB newborns and their mothers who treated in the Fourth Hospital of Shijiazhuang from 2018 to 2022 were participated in the study. The differences in clinical data were compared by the Mann-Whitney U test and Chi-square test.

The association between maternal iron, zinc, copper levels in serum and pregnancy outcomes.

Aims: To investigate the associations of serum trace elements (iron, zinc, and copper) between women with different pregnancy outcomes.

Methods: About 774 pregnant women who came to The Fourth Hospital of Shijiazhuang for prenatal examination were investigated. The concentrations of trace elements in the serum of pregnant women in the third trimester were collected.

Correlation between high serum ferritin levels and adverse pregnancy outcomes in women with gestational diabetes mellitus.

Aims: To explore the association between higher serum ferritin (SF) levels in mid-pregnancy and adverse pregnancy outcomes in gestational diabetes mellitus (GDM) pregnancies, then develop a predictive cut-off value that might effectively predict the risk of adverse pregnancy outcomes in future clinical.

Methods: The study involved 201 pregnant women with GDM. 201 gestational age and parity matched normoglycemic pregnant women were taken as control group.

The association between vitamin D levels in the second trimester of pregnancy and gestational diabetes mellitus.

Background And Aims: 25-hydroxyvitamin D (25(OH)D) affects glucose metabolism by increasing insulin secretion and insulin receptor expression. However, whether 25(OH)D deficiency will increase the risk of gestational diabetes mellitus (GDM) has not been clearly reported. The purpose of this study is to assess the relationship between vitamin D levels in the second trimester of pregnancy and the risk of GDM.

Kv7.4 channel is a key regulator of vascular inflammation and remodeling in neointimal hyperplasia and abdominal aortic aneurysms.

Inflammation has recently emerged as an important contributor for cardiovascular disease development and participates pivotally in the development of neointimal hyperplasia and abdominal aortic aneurysms (AAA) formation. Kv7.4/KCNQ4, a K channel, is one of the important regulators of vascular function but its role in vascular inflammation is unexplored.

Transcriptional Regulation of Voltage-Gated Sodium Channels Contributes to GM-CSF-Induced Pain.

Granulocyte-macrophage colony-stimulating factor (GM-CSF) induces the production of granulocyte and macrophage populations from the hematopoietic progenitor cells; it is one of the most common growth factors in the blood. GM-CSF is also involved in bone cancer pain development by regulating tumor-nerve interactions, remodeling of peripheral nerves, and sensitization of damage-sensing (nociceptive) nerves. However, the precise mechanism for GM-CSF-dependent pain is unclear.

Suppression of KCNQ/M Potassium Channel in Dorsal Root Ganglia Neurons Contributes to the Development of Osteoarthritic Pain.

Osteoarthritic pain has a strong impact on patients' quality of life. Understanding the pathogenic mechanisms underlying osteoarthritic pain will likely lead to the development of more effective treatments. In the present study of osteoarthritic model rats, we observed a reduction of M-current density and a remarkable decrease in the levels of KCNQ2 and KCNQ3 proteins and mRNAs in dorsal root ganglia (DRG) neurons, which were associated with hyperalgesic behaviors.
