Comparative Study[Comparative studies on the composition and antibiotic-resistance of pathogenic bacteria between children with community-acquired and hospital-acquired pneumonia].
This research was to explore the difference between children with community-acquired pneumonia (CAP) and hospital-acquired pneumonia (HAP) in the composition and antibiotic-resistance of pathogenic bacteria. ⋯ CAP was mainly comprised of Streptococcus pneumoniae and haemophilus influenza; while HAP was mainly comprised of Enterobacteriaceae and Non-fermenters. The drug resistance of gram-negative bacilli was higher in HAP than that in CAP.

[Analysis of antibiotic resistance and genotypes on extended spectrum β-lactamase and AmpC β-lactamase producing strains isolated from Uygur and Han newborns].
This study aimed to investigate drug resistance and genotypes of the extended spectrum β-lactamase (ESBLs) and AmpC β-lactamase-producing Escherichia coli and Klebsiella pneumoniae isolated from Uygur and Han newborns in Urumqi. ⋯ There were significant differences in antibiotic resistance and genotype distribution of Klebsiella pneumoniae and Escherichia coli between two nationality newborns, and these two bacteria detected in this study carried multi-resistance genes and showed high resistant to β-lactamase antibiotics.

Meta Analysis[Relationship between genetic polymorphisms of β2-adrenergic receptor gene and essential hypertension risk among the Han Chinese population: a Meta analysis].
To evaluate the relationship between A46G and C79G polymorphisms in the β2-adrenergic receptor (ADRB2) gene and the incidence of essential hypertension (EH) among the Han Chinese population. ⋯ Significant association was found between A46G polymorphism of ADRB2 gene and EH, whereas no association could be found between C79G polymorphism and EH among Han Chinese population.

[Application of disability adjusted life years in evaluating health effects due to particulate air pollution in Chinese cities].
To evaluate the loss of disability adjusted life years (DALYs) due to particulate air pollution in Chinese urban residents. ⋯ Substantial adverse health effects due to outdoor particulate air pollution were observed in China urban areas, thus strengthening air pollution control still remains an imperative and urgent matter in public health perspective.

[Effects of perfluorooctane sulfonate on learning and memory of rat pups].
To study the effects of prenatal and postnatal perfluorooctane sulfonate (PFOS) exposure on spatial learning and memory, N-methyl-D-aspartate receptor 2B (NR2B) mRNA and protein level in frontal cortex and hippocampus of rat pups and to explore the mechanism of developmental neurotoxicity induced by PFOS. ⋯ Prenatal and postnatal exposure to PFOS should result in the spatial learning and memory damage,and the mechanism might be possibly involved in the decrease of NR2B level in cerebral cortex and hippocampal formation regions.
