Objective To explore the correlation of rhinovirus infection and the morbidity of asthma in children.Methods The RV gene in nasopharyngeal secretion of 30 children with asthma acute exacerbation(asthma group),30 children in asthma clinical remission(remission group) and 30 healthy children (control group) were detected by reverse transcription-polymerase chain reaction(RT-PCR).The total serum IgE(T-IgE) was determined by chemiluminescence.The eosinophil(EOS) count (EOS%) of peripheral blood and lung function were also measured.Results The rhinovirus infection rate was 36.67% in asthma group and 3.33% in remission group.No rhinovirus was detected in control group.The rate of rhinovirus infections in asthma group was significantly highter than that in remission group and control group(?2=7.50,13.47 Pa0.05). FEV1% was (62.73?13.54)% in asthma rhinovirus infection and (86.42?17.78)% masthma with no rhinovirus infection.There was remarkable difference between 2 groups(F=14.553 P﹤0.05). The T-IgE was (836.32?44.801) kU/L and EOS% was 10.63?4.09 in asthma group with rhinovirus infection.The total IgE was (439.10?231.28) kU/L and EOS% was 5.04?2.64 in asthma group with no rhinovirus infection.There was significant difference between 2 groups(U=2.475,F=20.806 Pa0.05).Conclusions There is a close correlation between rhinovirus infection and acute attack of asthma(or worsening asthma) in children. Asthma exacerbations would be likely to happened easier because of rhinovirus infection in asthmatic children with high T-IgE.

Objective To explore the effect of sodium arsenite (iAs3+) and sodium hydrogen arseuate (iAs5+) exposure on rat multidrug resistance protein 2 (MRP2) expression,and the correlation of liver arsenic and its methylation products,and to provide a basis for further elucidating the mechanism of arsenic toxicity.Methods Seventy wistar rats were randomly divided into seven groups,10 rats in each group.Control group was administrated with deionized water.Sodiun arsenite high-dose group,middle-dose group,low-dose group were administrated with different concentrations of sodium arsenite:20.0,6.7 and 2.2 mg/kg BW every day,respectively.Animals were sacrificed 90 days later by cervical dislocation to collect liver,the expression of MRP2 in the membrane of hepatocyte was determined by Western blotting.HPLC-HGAFS was employed to determine the content or level of arsenic and its methylation products.Correlation between expression of MRP2 and arsenic methylation products was analyzed using Pearson's linear correlation method.Results The MRP2 protein levels of control group,iAs3+ and iAs5+ high-,middle-,low-dose groups were 1.21 ± 0.13,1.85 + 0.09,1.65 + 0.19,1.61 + 0.18,1.69 + 0.04,1.42 + 0.19,1.27 ± 0.10.Compared to control group,MRP2 protein levels of iAs3+ high-,middle-,low-dose group and iAs5+ high-dose group were increased (P < 0.05); Compared with the low-dose group,MRP2 protein levels of iAs3+ and iAs5+ high dose groups were increased(P < 0.05); Comparing the matched doses group of iAs5+ and iAs3+,MRP2 protein levels of iAs3+ high-,middle-,low-dose group were higher than iAs5+(P < 0.05).Meanwhile,there was a significant positive relationship between the expression of MRP2 and the content of iAs3+,MMA and DMA in iAs3+ exposed group(r =0.575,0.678,0.395,all P < 0.05).There was also a significant correlation between the expression of MRP2 and MMA and IMA in iAs5+ exposed group(r =0.593,0.643,all P < 0.05).There was no significant relationship between the expression of MRP2 and the content of iAs5+in iAs5+ exposed group.Conclusions The expression of MRP2 is increased with increasing dose of arsenic exposure,thus resulting in compensatory changes on MRP2 expression in the liver cell membrane.MRP2 efflux may play an important role in the metabolic pathways of iAs3+.The level or load of arsenic methylation in liver is closely related with MRP2 expression.
