To study the influence of HBV-DNA with different load levels of HBsAg-positive among fathers on the rate of neonatal cord blood HBV-DNA. Using HBsAg and HBV-DNA as screening indicators for pregnant women and their husbands from an obstetric clinic. 161 pregnant women whose HBsAg and HBV-DNA were negative, but HBsAg was positive among their husbands and their newborns, were selected. Blood samples from those pregnant women, their husbands and their newborns were collected to detect the related indicators. Using ELISA to detect hepatitis B virus markers (HBVM), and FQ-PCR to detect the levels of HBV-DNA load. According to neonatal cord blood HBV-DNA detection guideline, newborns with cord blood HBV-DNA positive were selected as cases, others as controls. (1) Result of the study showed that there was a dose-response relationship between paternal serum HBV-DNA load levels and neonatal cord blood HBV-DNA positive rates in newborns (trend χ(2) = 64.117, P = 0.000). The rate of vertical transmission of HBV from HBsAg-positive father to infant in the paternal serum HBV-DNA ≥ 1.0 × 10(7) copies/ml group was significantly higher than HBV-DNA < 1.0 × 10(7) copies/ml group (χ(2) = 71.539, P = 0.000). (2) There was a positive rank correlation between semen positive HBeAg and vertical transmission of HBV from HBsAg-positive father to infant (χ(2) = 6.892, P = 0.009). There was a dose-response relationship between paternal serum HBV-DNA load levels and neonatal cord blood HBV-DNA positive in newborns. Paternal serum HBV-DNA ≥ 1.0 × 10(7) copies/ml and with HBeAg positive status were risk factors of vertical transmission of HBV from HBsAg-positive father to infant. Source

To explore the relationship between gene polymorphism of GABAA receptors and childhood autism by detecting rs140682, rs2081648 and rs140679 site of single nucleotide polymorphism (SNP) in GABAA receptors gene. A total of 94 children with autism and 124 normal children were enrolled in a hospital from November 2010 to May 2011. Childhood autism rating scale (CARS) and autism behavior checklist (ABC) were used to evaluate or investigate the case group. After collecting venous blood and extracting the genome DNA, the allele and genotype of SNP rs140682, rs2081648 and rs140679 site in GABAA receptors gene were detected by PCR-RFLP. The allele and genotype of case group and control group were analyzed by χ(2) test, while the score of scales was analyzed by Spearman rank correlation analysis. The age of the case group was 5.12 ± 0.32, and it was 5.25 ± 0.27 in the control group (P < 0.05). In case group, the frequency of genotype CC, CT and TT of rs140682 site was 44, 41 and 9, while it was 48, 65, and 11 in control group (P > 0.05), respectively. The frequency of genotype AA, AG and GG of rs2081648 site was 8, 58 and 28 in case group, while it was 12, 49 and 63 in control group (P < 0.05), respectively. In case group, the frequency of genotype CC, CT and TT of rs140679 site was 15, 36 and 43, while it was 18, 59 and 47 in control group (P > 0.05), respectively. It was revealed by Spearman rank correlation analysis that of rs2081648 site, there was a positive correlation between genotype AG and sensation factor (S), social intercourse factor (R), and language factor (L) of autism behavior checklist (ABC) (r values were 0.149, 0.165 and 0.155, all P values < 0.05). A negative correlation between genotype GG and S, R, L and self-help factor (V) was proved (r values were -0.140, -0.173, -0.158 and -0.135, all P values < 0.05). There was a positive correlation between allele A and R and L factors (r values were 0.153 and 0.137, all P values < 0.05), while a negative correlation between allele G and R and L factors (r values were -0.153 and -0.137, all P values < 0.05). In case group, 42 children were diagnosed with mild-to-moderate autism, while 52 children were severe autism. There was no statistically significant correlation between allele or genotype of SNP rs140682 and rs140679 site and the degree of autism (P > 0.05). There was a positive correlation between allele A and genotype AG and the degree of autism (r values were 0.147 and 0.616, all P values < 0.05), while a negative correlation between allele G and genotype GG and the degree of autism (r values were -0.159 and -0.616, all P values < 0.05). The SNP rs2081648 site which located in GABAA receptors gene may be related to autism. No evidence for significant association between rs140682 and rs140679 site and autism was found. Source

Zinc has been implicated to have a protective role against heart malformations during fetal development. Metallothionein 1 (MT-1) and zinc transporter 1 (ZnT-1) are two major metabolic factors that are associated with zinc metabolism. The present work aimed to investigate the association of placental MT-1 and ZnT-1 expressions with fetal heart malformations resulting from maternal zinc deficiency. Sprague–Dawley female rats were randomly divided into five groups of extremely low-zinc, low-zinc, moderately low-zinc, marginally low-zinc and normal zinc (n = 9–12), and were fed diets with controlled zinc content at 1.0 ± 0.3, 8.4 ± 1.8, 15.4 ± 2.8, 22.4 ± 4.1 and 29.4 ± 5.3 [mean ± standard deviation (SD)] mg of zinc/kg, respectively, from day 25 of preconception until day 19 of gestation. The female rats were bred, their fetuses were harvested at day 19 of gestation after killing the dams, and fetal hearts were morphologically examined. Zinc concentration and alkaline phosphatase (ALP) activity in maternal venous blood sera were tested, and MT-1 and ZnT-1 mRNA expressions in the placenta were assayed. Zinc concentrations and ALP activities in the blood were low in all zinc-deficient diet groups in a dose-dependent fashion. The incidences of heart malformations were increased, and the levels of placental MT-1 and ZnT-1 mRNA expressions were decreased in the extremely low-zinc, low-zinc and moderately low-zinc groups compared with the normal zinc group. Specifically, mRNA levels of placental MT-1 or ZnT-1 were significantly decreased and were lower than the specific threshold values in the fetuses with heart malformations but not in the fetuses without heart malformations in all the groups. These data indicate that maternal zinc deficiency resulted in an elevated incidence of fetal heart malformations, which was associated with significant decreases in placental MT-1 and ZnT-1 mRNA expressions to the levels below the threshold values that may be a crucial factor to determine the presence of fetal heart malformations. © 2014, Springer Science+Business Media New York.

Introduction: This study is to evaluate the association of polymorphisms of glutathione S-transferase P1 (GSTP1), copper-transporting P-type adenosine triphosphatase A (ATP7A) and X-ray repair cross-complementing group 1 (XRCC1) with the efficacy and toxicity of cisplatin-based treatment in advanced non-small cell lung cancer (NSCLC) patients. Materials and methods: The outcomes of 97 advanced non-small cell lung cancer patients treated with cisplatin-based chemotherapy were estimated. GSTP1, ATP7A, and XRCC1 genetic polymorphisms were determined via polymerase chain reaction of restriction fragment length polymorphism (PCR–RFLP) and DNA sequencing. Association of the polymorphisms with the efficacy and toxicity of cisplatin was analyzed, respectively. Results: Significant associations were observed between GSTP1 A313G and response rate (RR) (p = 0.027), disease control rate (DCR) (p = 0.019), and progression-free survival (PFS) (p = 0.044), respectively. Patients with AG and GG of GSTP1 have notably lower risk of anemia (p = 0.046). XRCC1 A1196G was associated with the incidence of lymphopenia (p = 0.024) and diarrhea (p = 0.020). ATP7A C2299G was not related with RR, DCR, PFS, and the risk of toxicity. Conclusions: Advanced NSCLC patients with AA genotype of GSTP1 would obtain better curative effect followed with more risk of anemia when treated by cisplatin-based chemotherapy. ATP7A C2299G does not impact the efficacy and toxicity of cisplatin-based chemotherapy. XRCC1 1196A allele could predict the incidence of lymphopenia and diarrhea. © 2015, Federación de Sociedades Españolas de Oncología (FESEO). Source

OBJECTIVE: To study the impacts of pre-pregnancy maternal BMI and gestational weight gain(GWG) on pregnancy outcomes.METHODS: We adopted a prospective cohort study with cluster sampling in single pregnant women, who were not with hypertension, diabetes, hyperlipidemia or other diseases in the previous history, neither did they have diseases of heart, liver, kidney, thyroid etc. related to current pregnancy. Those pregnant women who visited the prenatal nutrition clinic under 'informed consent' were surveyed with questionnaire to track their peri-natal complications, delivery mode and neonate birth outcomes etc. Pearson and partial correlations, chi-square test and binary logistic regression were used to study the association between pre-pregnancy maternal BMI, GWG and pregnancy outcomes.RESULTS: A total of 623 pregnant women were recruited in the cohort, with 592 (95%) of them eligible for analysis. Results from the Multivariate Logistic Regression analysis indicated that, after controlling the potential confounding factors, when compared to women with pre-pregnancy BMI between 18.5 and 24.0, the odds ratios (ORs) for low birth ponderal index (PI) were 2.34 [95% confidence interval (CI), 1.24-4.42)]among those with BMI<18.5, respectively, while 2.73 (1.12-6.68) for high birth PI among those with BMI > 24.0. Similarly, when compared to pregnant women with normal GWG(defined as weight gain range from P15 to P85 by stratification of pre-pregnancy BMI), low GWG (P 85)appeared the risk factor for high birth weight, high birth PI, and gestational diabetes mellitus, with ORs as 3.83(1.74-8.44), 2.39(1.14-5.01)and 2.21(1.07-4.55), respectively.CONCLUSION: Low or high pre-pregnancy maternal BMI and GWG were associated with adverse pregnancy outcomes.
