Relationship between diagnosis of conus arteriosus malformation and genetic diagnosis results in fetal cardiac axis abnormalities by echocardiography during middle pregnancy.

Objective: To explore the clinical value of echocardiography in detecting fetal cardiac axis abnormalities during middle pregnancy for diagnosing conus arteriosus malformation, and to compare and analyze the genetic diagnosis results, in order to provide evidence for clinical diagnosis and intervention.

Methods: Four hundred twenty-one fetuses with conus arteriosus malformation from January 2020 to October 2023 were included as the conus arteriosus malformation group, and 917 healthy fetuses (all single fetuses) matched at the same gestational age were selected as the healthy group.

Results: There was no significant difference in gestational weeks between two groups ( > 0.

The Sonographic Features of Malformation in Fetal Echogenic Bowel and Its Relationship With Chromosome Abnormalities.

The aims of this study were to analyze the sonographic features and clinical prognosis of fetal echogenic bowel (FEB) and to evaluate the value of FEB in the prediction of fetal chromosomal abnormalities. Eight hundred eighty-two fetuses with FEB were selected. The ultrasonographic features and the chromosomal examination were retrospectively analyzed.

Evaluation of ultrasonography in fetal intestinal malrotation with midgut volvulus.

Objectives: To investigate the clinical significance of prenatal diagnosis and prognostic evaluation of fetal intestinal malrotation with midgut volvulus via ultrasonography.

Material And Methods: Ultrasonographic findings and clinical outcomes of fetal intestinal malrotation with midgut volvulus prenatally diagnosed via ultrasound at the Zhangzhou Hospital Affiliated of Fujian Medical University from January 2013 to May 2020 were summarised and analyzed.

Results: Eleven cases of fetal intestinal malrotation with midgut volvulus were accurately prenatally diagnosed according to the specific ultrasound signs, such as 'whirlpool sign' and 'twining sign'.

Diagnostic Efficiency of Gynecologic Imaging Reporting and Data System Combined With 3-dimensional Contrast-enhanced Ultrasound Scoring System in Evaluating Ovarian Tumor.

To estimate the value of gynecologic imaging reporting and data system (GI-RADS) combined with 3-dimensional contrast-enhanced ultrasound (3D-CEUS) scoring system in the differential diagnosis of ovarian tumor. Both of 2-dimensional ultrasound (2D-US) and 3D-CEUS were performed on 114 patients with ovarian masses by Voluson E8 with SonoVue (Bracco, Italy). Besides, dynamic contrast-enhanced-magnetic resonance imaging (DCE-MRI) (Siemens Magneton Verio 3.

A bacterial polysaccharide biosynthesis-related gene inversely regulates larval settlement and metamorphosis of .

Larval settlement and metamorphosis is essential for the development of marine invertebrates. Although polysaccharides are involved in larval settlement and metamorphosis of , the molecular basis of polysaccharides underlying this progression remains largely unknown. Here, the roles of the polysaccharide biosynthesis-related gene of ECSMB14103 in the regulation of larval settlement and metamorphosis were examined by gene-knockout technique.
