OBJECTIVE This study aimed to assess risk factors for mother-to-child transmission (MTCT) of hepatitis B virus (HBV) after immunoprophylaxis. METHODS Risk factors for MTCT were assessed using a multivariate logistic regression model. PATIENTS We enrolled 256 mother-child pairs with positive maternal hepatitis B surface antigens (HBsAg) between January(More)
Fourteen new diterpenoids including clerodane (1-12), labdane (13), and norlabdane (14) types, as well as nine known analogues were isolated from the aerial parts of Croton laui. Their structures were established on the basis of spectroscopic analysis, and that of crotonolide H (11) was confirmed by single-crystal X-ray crystallography. Crotonolide A (1)(More)
AIM To study the chemical structure of SC3, an acidic polysaccharide from Salvia chinesis. METHODS Based on chemical (including sugar composition analysis, methylation analysis, uronic acid reduction and partial acid hydrolysis) and spectral analysis (IR, NMR, ESI-MS), the structural characterization of SC3 was investigated. RESULTS SC3 was composed(More)
The hepatitis B virus(HBV) polymerase rtA181T mutation is selected during long-term antiviral therapy. As the polymerase gene completely overlaps with the envelope (S) gene, HBV rtA181T mutation also carries sW172 mutations. In this study, we investigated whether there were biological differences between rtA181T/sW172* (coding truncated HBsAg) and(More)
This study was designed to evaluate the diagnostic value of common inflammatory markers with regard to fever of unknown origin (FUO). We investigated 383 patients who were hospitalized with FUO at the Henan Province People's hospital between January 2009 and June 2015. Of all the cases, infectious diseases accounted for 33.9%, neoplasms for 21.1%, collagen(More)
Three new ring B-seco limonoids, ciliatonoids A-C (1-3), were isolated from Toona ciliate and structurally characterized by spectroscopic data, X-ray crystallography, and electronic circular dichroism analysis. Ciliatonoids A and B feature an unprecedented limonoid architecture, while ciliatonoid C belongs to a rare class of limonoids. Biological evaluation(More)
OBJECTIVE The aim of the present study was to investigate the difference of intolerance to food between southern and northern middle-aged Chinese, and furthermore analyze its association with eating habits in both study population. METHODS ELISA was applied to determine the serum concentrations of specific IgG of 14 food anaphylactogen in 1568 healthy(More)
OBJECTIVE To investigate the effective clinical diagnosis and treatment for allergic rhinitis (AR) by examining the allergens and dietary habits of the patients. METHODS A total of 347 patients from Lanzhou area were sampled between April 2010 and March 2012. Free point skin prick test were performed to analyze the allergens. SPSS 17.0 software was used(More)
OBJECTIVE To study methylation of Id4 gene and demethylation effect of arsenic trioxide (ATO) in Raji cells. METHODS Human Burkitt's Raji lymphoma cells were cultared and treated with ATO at different concentrations and different time points. Methylated degree of Id4 gene was detected by methylation specificity polymerase chain reaction (MS-PCR), Id4 mRNA(More)
2,3,7,8-Tetrachlrodibenzo-p-dioxin (TCDD) has been shown to induce cleft palate through growth factor and receptor expression changes during palatogenesis. DNA methylation is an important epigenetic modification that can regulate gene expressions and may be involved in TCDD-induced cleft palate. In this study, we investigated the effects of TCDD on the(More)
