OBJECTIVETo study influenza epidemic and analyze antigenic and genetic characterization of the predominant strains in Wuhan area in 2003.

METHODSEpidemiological data and specimens from influenza patients were collected from surveillance sites weekly. Viruses were isolated from the specimens. Three H3 isolates were chosen to do antigenic analysis by hemagglutination inhibition (HI) test and their HA1 region was sequenced.

RESULTSTotally 58 influenza viruses were isolated from 418 specimens, 57 of them were identified as H3 subtype and 1 of them was B subtype; both monthly positive rate and numbers of influenza like illness had two peaks of winter and summer, the highest peak appeared in July. The 3 new H3 isolates were antigenically different from vaccine strain A/Panama/2007/99, 14 amino acid changes have been found in HA1 domain of these 3 strains compared with A/Panama/2007/99, phylogenetic analysis also confirmed the difference in HA1 domain.

CONCLUSIONSInfluenza epidemic had two peaks in Wuhan area in 2003. The activity of H3 virus was strengthened remarkably. And they are antigenically and genetically different from the vaccine strain.

Maternal and child health is an important issue throughout the world. Given their impact on maternal and child health, nutritional issues need to be carefully addressed. Accordingly, the effect of maternal, child, and nutritional disorders on disability-adjusted life years (DALYs) should be calculated. The present study used DALYs to estimate the burden of disease of maternal, neonatal, and nutritional disorders in the Korean population in 2012. For this purpose, we used claim data of the Korean National Health Insurance Service, DisMod II, and death data of the Statistics Korea and adhered to incidence-based DALY estimation methodology. The total DALYs per 100,000 population were 376 in maternal disorders, 64 in neonatal disorders, and 58 in nutritional deficiencies. The leading causes of DALYs were abortion in maternal disorders, preterm birth complications in neonatal disorders, and iron-deficiency anemia in nutritional deficiencies. Our findings shed light on the considerable burden of maternal, neonatal, and nutritional conditions, emphasizing the need for health care policies that can reduce morbidity and mortality.

OBJECTIVETo evaluate the effect of prenatal and lactational exposure to brominated diphenyl ethers-209 (BDE-209) on the expression of growth associated protein-43 (GAP-43) and brain-derived neurotrophic factors (BDNF) in the hippocampus of the offspring rats.

METHODSPeanut oil suspensions of commercial BDE-209 were administered daily at doses of 100, 300, 600, and 1200 mg/kg by oral gavage in pregnant Wistar rats (groups A, B, C, and D, respectively). The control group (E) only received peanut oil of an equivalent volume. The hippocampus was isolated from 10 offspring rats in each group to determine the expression of GAP-43 and BDNF using immunohistochemistry.

RESULTSThe GAP-43 in the BDE-209-treated groups were lower than that of the control group, and decreased with the increase of the dose of BDE-209 exposure. The groups C and D (P=0.013, P=0.000), but not the groups A and B (P=0.177, P=0.093), showed significant difference from the control group in GAP-43 expression. The positive expression of BDNF in the hippocampus was decreased as the exposure dose to BDE-209 increased, and significant differences were found between the groups B, C, D and the control group (P=0.033, P=0.005, P=0.001, respectively), but not between group A and the control group (P=0.066).

CONCLUSIONSMaternal BDE-209 exposure can decrease the expression of GAP-43 and BDNF in the hippocampus of offspring rats, which may affect the axonal plasticity and regeneration of the neurons.

OBJECTIVETo investigate the effect of maternal brominated diphenyl ethers-209 (BDE-209) exposure on the learning and memory ability of the offspring rats in prenatal and lactational periods.

METHODSAfter confirmation of successful mating, female Wistar rats were randomized into 5 groups and subjected to daily oral gavage of peanut oil suspensions containing BDE-209 at the doses of 100 mg/kg (group A), 300 mg/kg (group B), 600 mg/kg (group C), and 1200 mg/kg (group D), or only peanut oil (group E, as control). From each group, 20 male weaning rats of the first generation were randomly selected to examine their learning and memorizing ability using Morris water maze. The histological alterations of the hippocampus were observed microscopically with HE staining after the test.

RESULTSDuring the initial one or two days of water maze test, no significant difference was noted in the escape latency between the groups (P=0.068, P=0.104). On days 3 to 5, groups B, C, and D showed prolonged escape latency as compared with the control group (P<0.05), but group A showed no such changes (P>0.05). Under optical microscope, the hippocampus in groups A and B exhibited no significant variation from that of the control group, but in groups C and D, the neural cells were obviously reduced and presented disorderly alignment, with substantial cell nuclear shrinkage and interstitial edema.

CONCLUSIONMaternal BDE-209 exposure induces disturbance of the learning and memorizing ability and pathological changes of the hippocampus in the offspring rats, and these changes show a dose-effect relation.

The aim of this study was to label rabbit bone derived mesenchymal stem cells (BMSCs) with superparamagnetic iron oxide particles (SPIO) and to study the effects of magnetic labeling on the multi-differentiation of BMSCs. Rabbit BMSCs were isolated, purified, expanded, then coincubated with SPIO(25 microg/ml) complexed to protamine sulfate (Pro) transfection agents overnight. Prussian blue staining and transmission electron microscopy were performed to show intracellular iron. Cell differentiation was evaluated. Both labeled and unlabeled BMSCs were subjected to osteogenic, adipogenic and chondrogenic differentiation to assess their differentiation capacity for 21 d. Osteogenic cells were stained with alizarin red to reveal calcium deposition, adipogenic cells were stained with oil redO' respectively. Chondrogenic cells stained with Safranin-O, glycosamino glycans, and type II collagen production was assessed by standard immunohistochemistry. Cell with immunohistochemistry staining were detected by polarized light microscopy and analysed by Image-Pro Plus software. The results showed that intracytoplasmic nanoparticles were stained with Prussian blue and observed by transmission electron microscopy clearly except the unlabeled control. As compared with the nonlabeled cells, it showed no statistically significant difference on the differentiation of the labeled BMSCs. And the differentiation of the labeled cells were unaffected by the endosomal incorporation of SPIO. In summary, BMSCs can be labeled with SPIO without significant change in cell multi-differentiation capacity.
