The correlation between blood-lipid ratio in the first trimester and large-for-gestational-age infants.

BACKGROUND: To investigate the correlation between maternal glucose and lipid metabolism indexes and blood-lipid ratio in the first trimester and large-for- gestational-age (LGA) infants. METHODS: Women in the first trimester of pregnancy who underwent regular obstetric examination in the obstetric outpatient department of the Affiliated Hospital of Chengde Medical College from June 2018 to March 2019 were included according to the standard. Basic information were collected based on questionnaires at the first visit of pregnant women, including early fasting blood glucose (FBG), fasting insulin (FINS), glycated hemoglobin (HbA1c), high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglyceride (TG), total cholesterol (TC), apolipoprotein A1 (APO-A1), apolipoprotein B (APO-B), lipoprotein a (LP(a)), LDL/HDL, TG/HDL, TC/HDL, APO-B/APO-A1 ratio, birth weight of newborns, gestational age at delivery etc. RESULTS: A total of 418 cases were included for analysis. The incidence rate of LGA infants was 13.88%, and that of small-for-gestational-age (SGA) infants was 4.78%. Univariate analysis revealed that the age, pre-pregnancy body mass index (BMI), weight gain during pregnancy, APO-B/APO-A1 between LGA group and appropriate-for-gestational-age (AGA) group were significantly different (P < 0.05); multivariate stepwise logistic regression analysis indicated that the correlation between maternal age, pre-pregnancy BMI, weight gain during pregnancy, APO-B/APO-A1 level and LGA were statistically significant (P < 0.05); compared with the reference range of APO-B/APO-A1 of 0.46-0.65, values < 0.46 and > 0.65 were protective factor of LGA (P < 0.05). The receiver operating curve(ROC) indicated that the area under the curve (AUC)s for predicting LGA using maternal age, pre-pregnancy BMI, weight gain during pregnancy, and early pregnancy APO-B/APO-A1 were 0.585, 0.606, 0.637, 0.531, respectively. The AUC for a combined prediction model was 0.742, showing greater predictive value than any other factors individually. CONCLUSION: Maternal age, pre-pregnancy BMI, weight gain during pregnancy, and APO-B/APO-A1 levels in first trimester are significant factors influencing the occurrence of LGA infants, and the combination of the four factors would have certain predictive value for LGA.

An Intervention Study on Children's Healthy Joint Attention Skills Based on a Mixed Instructional Approach of DTT and PRT.

Joint attention is an important element that influences children's early development of communication and sociality, and joint attention is more often than not the earliest incipient of their prosocial behavior. Joint attention skills are one of the core deficits of children with autism, and identifying and remediating the core problems of autism is a popular area of interest, with joint attention being the focus of attention. The aim of this study was to investigate whether the combined orientation model of Discrete Trial Teaching (DTT) and Pivotal Response Training (PRT) could improve the joint attention skills of children with autism. This study used a cross-behavioral multitest design in a single-subject study with two preschool children with autism as subjects, with the independent variable being joint attention teaching and the dependent variable being the three joint attention skills (eye gaze, following directions, and active display). After the instructional intervention, children with autism showed a significant increase in the correctness of "eye alternation," "following directions," and "moving displays."

MiR-27a-3p/Hoxa10 Axis Regulates Angiotensin II-Induced Cardiomyocyte Hypertrophy by Targeting Kv4.3 Expression.

Cardiac hypertrophy is a common pathological process of various cardiovascular diseases, which is often accompanied with structural and electrical remodeling, and can even lead to sudden cardiac death. However, its molecular mechanism still remains largely unknown. Here, we induced cardiomyocyte hypertrophy by angiotensin II (Ang II), and found that miR-27a-3p and hypertrophy-related genes were up-regulated. Further studies showed that miR-27a-3p-inhibitor can alleviate myocardial hypertrophy and electrical remodeling. Moreover, luciferase assay confirmed that miR-27a-3p could regulate the expression of downstream Hoxa10 at the transcriptional level by targeting at its 3'UTR. At the same time, the protein expression of Hoxa10 was significantly reduced in Ang II-treated cardiomyocytes. Furthermore, overexpression of Hoxa10 can reverse myocardial hypertrophy and electrical remodeling induced by Ang II in cardiomyocytes. Finally, we found that Hoxa10 positively regulated the expression of potassium channel protein Kv4.3 which was down-regulated in hypertrophic cardiomyocytes. Taken together, our results revealed miR-27a-3p/Hoxa10/Kv4.3 axis as a new mechanism of Ang II-induced cardiomyocyte hypertrophy, which provided a new target for clinical prevention and treatment of cardiac hypertrophy and heart failure.

The efficacy and safety of Dl-3n-butylphthalide on progressive cerebral infarction: A randomized controlled STROBE study.

Progressive cerebral infarction (PCI) is associated with high rates of mortality and disability. Many studies have shown that Dl-3n-butylphthalide (NBP) is effective against acute ischemic stroke. The administration of NBP can result in an increased number of capillaries in the ischemic region, promote the establishment of collateral circulation, protect the mitochondria, and narrow the infarction area, among other effects. In the present study, we evaluated the efficacy and safety of NBP for the treatment of PCI.Between March 2008 and May 2012, we performed a randomized, double-blind placebo-controlled study including 304 inpatients with PCI. These patients were randomly assigned to the test (152 cases) and control groups (152 cases). The test group received 200 mg of NBP soft capsules orally, 15 minutes before each meal, 3 times daily. The control group received 200 mg of placebo soft capsules orally, 15 minutes before each meal, 3 times daily. Treatment was administered during 21 days. The National Institute of Health Stroke Scale (NIHSS) score was assessed before the treatment and on days 7, 14, 21, and 30 after treatment. The Barthel index (BI) was assessed on the same days and on day 90.In the test group, the NIHSS scores on days 7, 14, 21, and 30 were 14.75 ±â€Š4.85, 11.62 ±â€Š3.49, 8.87 ±â€Š5.17, and 6.38 ±â€Š4.93, respectively. In the control group, they were 16.08 ±â€Š3.76, 13.28 ±â€Š5.02, 11.05 ±â€Š4.25, and 8.43 ±â€Š5.41 (P < .05), respectively. The BI on days 7, 14, 21, 30, and 90 were 51.57 ±â€Š15.11, 61.21 ±â€Š16.39, 70.48 ±â€Š18.21, 76.41 ±â€Š19.02, and 81.10 ±â€Š15.52 for the test group and 46.79 ±â€Š18.42, 55.93 ±â€Š19.12, 64.84 ±â€Š17.67, 70.65 ±â€Š18.54, and 76.54 ±â€Š17.05 for the control group (P < .05), respectively. Adverse events were elevation of alanine aminotransferase and aspartate aminotransferase (P > .05).NBP was useful to improve the outcome of patients with PCI and decreased their disability for activities of daily living. NBP was an efficacious and safe treatment for PCI.

Comparative genomic in situ hybridization (cGISH) analysis of the genomic relationships among Sinapis arvensis, Brassica rapa and Brassica nigra.

To further understand the relationships between the SS genome of Sinapis arvensis and the AA, BB genomes in Brassica, genomic DNA of Sinapis arvensis was hybridized to the metaphase chromosomes of Brassica nigra (BB genome), and the metaphase chromosomes and interphase nucleus of Brassica rapa (AA genome) by comparative genomic in situ hybridization (cGISH). As a result, every chromosome of B. nigra had signals along the whole chromosomal length. However, only half of the condensed heterochromatic areas in the interphase nucleus and the chromosomes showed rich signals in Brassica rapa. Interphase nucleus and the metaphase chromosomes of S. arvensis were simultaneously hybridized with digoxigenin-labeled genomic DNA of B. nigra and biotin-labeled genomic DNA of B. rapa. Signals of genomic DNA of B. nigra hybridized throughout the length of all chromosomes and all the condensed heterochromatic areas in the interphase nucleus, except chromosome 4, of which signals were weak in centromeric regions. Signals of the genomic DNA of B. rapa patterned the most areas of ten chromosomes and ten condensed heterochromatic areas, others had less signals. The results showed that the SS genome had homology with AA and BB genomes, but the homology between SS genome and AA genome was clearly lower than that between the SS genome and BB genome.
