Evaluating fetal heart morphology in hypertensive disorders of pregnancy using the fetal heart quantitative technique.

Background: This study sought to explore the clinical application value of fetal heart quantification (HQ) technology in the evaluation of fetal heart morphology in hypertensive disorders of pregnancy (HDP).

Methods: Fetal HQ software was used to quantitatively analyze the 4-chamber global sphericity index (GSI) and 24-segment sphericity index (SI) and Z scores of 53 normal fetal hearts (the normal group) and 26 fetal hearts with gestational hypertension (the case group). The normal Z value range was set at -2 to 2.

Fitness and Rhizobacteria of F2, F3 Hybrids of Herbicide-Tolerant Transgenic Soybean and Wild Soybean.

The introduction of herbicide-tolerant (HT) transgenic soybeans ( (L.) Merr.) into farming systems raises great concern that transgenes may flow to endemic wild soybeans ( Sieb.

A preliminary study on fetal cardiac morphology and systolic function of normal and anemic pregnant women by fetal heart quantification technology.

Background: Maternal anemia is a common nutritional problem during pregnancy. Fetal heart quantification (fetal HQ) technology is used to quantitatively evaluate the size, shape, and contractile function of the fetal heart, which can reflect the development of the fetus in the uterus.

Methods: We used fetal HQ technology to evaluate the basal-apical length (BAL), the transverse width (TW) and the area (A) of the four chamber view at end-diastole in 77 normal fetuses and 40 fetuses of women with anemia.

Study on normal reference value of fetal facial profile markers during the first trimester of pregnancy.

Background: To establish a normal reference value for fetal facial profile markers during the first trimester of pregnancy.

Methods: We collected the data of 800 pregnant women who were examined during early pregnancy. The range of values of inferior facial angle (IFA), frontal nasal-mental (FNM) angle, frontomaxillary facial (FMF) angle, mandibulomaxillary facial (MMF) angle, fetal profile line (FPL), and maxilla-nasion-mandible (MNM) angle in normal fetuses of 11-13 weeks was measured and correlated.

The value of outflow tract flow tracing in early pregnancy in the screening of structural malformations of fetal cardiac great arteries.

Background: To explore the application value of outflow tract "" blood flow in screening fetal cardiac macrovascular structural malformations in early pregnancy.

Methods: A total of 3,356 pregnant women who underwent nuchal translucency (NT) screening during early pregnancy in the prenatal diagnosis center of General Hospital of Ningxia Medical University from January 2017 to December 2018 were taken as the research objects, and the fetuses were systematically screened by ultrasound. The display of four chamber cardiac blood flow, X-shaped blood flow of main pulmonary artery, V-shaped blood flow of three vessel trachea and "" shaped blood flow of outflow tract were observed and recorded.

Study on the application of ultrasonography in the diagnosis of fetal cardiac structural abnormalities and the relationship between fetal cardiac structural abnormalities with chromosome abnormalities in early pregnancy.

Background: To explore the significance of multiple ultrasonic soft indexes such as Nuchal translucency (NT) in detection of cardiac structural malformations and chromosome abnormalities in fetal systematic screening in the first trimester, and to understand the value of combined transvaginal ultrasound (TVUS) in congenital heart disease (CHD) screening.

Methods: A total of 3,356 pregnant women who underwent early NT screening were screened by systematic ultrasound to monitor and evaluate the sensitivity and specificity of NT, tricuspid valve (TV), ductus venosus (DV) in the diagnosis of fetal CHD. According to the different intervals of NT thickening, the patients were divided into four groups, the detection rates of CHD and abnormal karyotypes in each group were compared, and the consistency of transabdominal and combined transvaginal ultrasonography was compared.

Diagnosis of retrotracheal left brachiocephalic vein with prenatal ultrasound: a case report.

Retroesophageal or retrotracheal left brachiocephalic vein (LBCV) is a rare anatomic variant that is often associated with congenital heart disease. It is rarely reported in fetal life, and an isolated fetal retroesophageal LBCV has a good prognosis: it is typically asymptomatic, although respiratory symptoms or swallowing disorders occasionally occur. A variant was observed on fetal echocardiography at 22 weeks of gestation.

Surfactant-facilitated alginate-biochar beads embedded with PAH-degrading bacteria and their application in wastewater treatment.

Immobilized Pseudomonas aeruginosa beads with alginate and biochar as composite carriers and a nonionic surfactant (TX100) as degradation promoter were prepared by the gel embedding method. The optimal preparation parameters for the biochar addition amount and the concentrations of the bacterial suspension and TX100 were 1%, OD = 1 and 200 mg/L, respectively. The addition of TX100 can simultaneously promote biochar sorption of PAHs and PAH degradation by P.

Removal of acenaphthene from water by Triton X-100-facilitated biochar-immobilized .

By adding the nonionic surfactant Triton X-100 and using biochar as an immobilization carrier, a Triton X-100-facilitated biochar-immobilized (TFBIP) material was prepared using the sorption method and was used to treat acenaphthene in water. The results showed that a low concentration of Triton X-100 simultaneously promoted the sorption capacity of the biochar and the degradation activity of , thereby significantly enhancing the removal of acenaphthene from water by the immobilized material. Compared with the control without Triton X-100, a low concentration of Triton X-100 significantly increased the acenaphthene removal rate by 20-50%.

Effects and mechanisms of anionic and nonionic surfactants on biochar removal of chromium.

This work found that the removal of chromium by a straw-derived biochar was significantly promoted or inhibited by various surfactants. For example, the anionic surfactant sodium dodecyl benzene sulfonate (SDBS) inhibited the removal of Cr(VI) by the biochar but significantly promoted the removal of Cr(III) by the biochar. The nonionic surfactant Triton X-100 (TX-100) promoted the removal of Cr(VI) at low concentrations (< 100 mg L) but inhibited the removal at high concentrations.
