Objective To investigate the new epidemiology and clinical manifestation of measles in children in recent years. Methods One hundred and twenty-eight cases of children′s measles were collected,and their epidemiological and clinical characteristics of age distribution,endemic distribution,vaccination,clinical manifestation,complication and misdiagnosis were discussed. Results Among the patients living in urban,90% cases were single dose vaccination,35% cases were between 3-8 years old,27% cases were less than 8 months old,59% cases were mild measles,27% cases were atypical measles,40% cases were misdiagnosed at first visit,and 67% cases of measles less than 8 months old were babies of vaccine immunized mother.Among the patients living in rural,68% cases had no vaccination,86% cases were at age of typical onset,61% cases were typical measles,7% cases were severe measles,and 28% cases were mild measles.Among all cases of measles,mild measles and atypical measles were as high as 41% and 16%,but typical measles were only 37%.In all patients,56% cases had typical measles rash,82% cases had Koplik′s spots,77% cases had typical onset of eruption,100% cases had higher fever in eruption stage,89% cases had typical downward sequence of eruption,93% cases had skin pigmentation,and 81% cases had desquamation. Conclusions Less than 8 months infants and single dose vaccinated pre-school children are newly susceptible group of measles.Mild measles and atypical measles markedly increased,with atypical clinical symptoms,variable rash and variant onset,but the character of aggravated fever in eruption stage scarcely changes.Infants of vaccine immunized mother and pre-school children are advised to vaccinate ahead of schedule.

ObjectiveTo investigate the iodine nutritional status of residents in Shanxi province,and to provide a scientific basis for adjustment of control strategies and measures to iodine deficiency disorders (IDD).MethodsIn the 11 cities and 119 counties(cities,districts),except high water iodine townships,9 townships were selected in each county according to their sub-area positions of east,west,south,north and center,4 villages were sampled in each chosen township,and 8 households were selected in each chosen village in every chosen county (cities,districts ) with 9 or more townships.In every chosen county (cities,districts) with 6 to 9 townships,1 township was selected respectively in east,west,south,north and center sub-areas of the township,4 villages were sampled in each chosen township,and 15 households were selected in each chosen village.In the county (cities,districts) with 5 or less townships,all township were selected,4 villages were sampled in each chosen township,and 15 households were selected in each chosen village.Edible salt samples from these households were collected; iodized salt was determined by direct titration.In the 119 counties(cities,districts),1 township was selected,respectively,in east,west,south,north and center sub-areas in each county,and 20 children aged 8 - 10 in each of the selected townships were selected to collect urine samples and urinary iodine was determined by As-Ce catalytic spectrophotometry.Evaluation criteria:median urinary iodine ＜ 100 μg/L was iodine deficiency,100 - 199 μg/L as appropriate,200 - 299 μg/L as more than appropriate,and ≥ 300 μg/L as iodine excess.ResultsMedian iodine of the 34 808 household salt samples was 31.55 mg/kg.The coverage rate of qualified iodized salt was 99.18％(34 521/34 808) and the consumption rate of qualified iodized salt was 97.12％(33 805/ 34 808).In the 11 cities,119 counties(cities,districts),the median of urinary iodine of 11 967 children aged 8 -10 was 244.0 μg/L,of which ＜ 50 μg/L acoounted for 2.6％(312/11 967),50 - 99 μg/L accounted for 6.9％(823/11 967),100- 199 μg/L accounted for 26.3％(3145/11 967),200 - 299 μg/L accounted for 28.7％(3440/11 967),and 300 μg/L or higher accounted for 35.5％(4247/11 967).The medians of urinary iodine in the 9 municipal cities were 200 - 300 μg/L,and other 2 cities were 300 - 400 μg/L At the county level,the medians urinary iodine of children of the 119 counties(cities,districts) were 100 - 199 μg/L that accounted for 15.1％(18/119),200 - 299 μg/L accounted for 63.9％(76/119),and 300 μg/L or higher accounted for 21％(25/119).Conclusions The iodine nutrition level of residents in Shanxi province is more than appropriate.The salt iodine concentration in Shanxi province needs to be reduced,but the space is not wide.

Orjective:To obtain recombinant CHO-K1 with expressing sPDGFR? and to identify the biological activities of sPDGFR? secreted in non-serum medium.Methods:Recombinant human sPDGFR? expression vector pIRES-Neo3-sPDGFR?-Fc was constructed and then transfected into CHO-K1 cells by using LipofectamineTM 2000.After screened with G418 in 8 weeks,some monoclone cells were selected randomly to amplify in 96-well-plate to 24-well-plates,and then to identify positive cell clones by RT-PCR.Furthermore,the candidate cell clones were test by Real-Time PCR and Western blot assays.Finally,anti-proliferation activities of the expressed sPDGFR? were analyzed by MTT.Results:sPDGFR?-Fc was cloned into pIRES-Neo3 correctly.The sPDGFR?-Fc expression level in recombinant CHO-K1 cell clones were concordant in between Realtime PCR and Western blot assay.sPDGFR?-Fc obtained from cultured non-serum medium of positive CHO-K1 could significantly inhibit proliferation of vascular endothelial cell.Conclusion:Successed to select recombinant CHO-K1 cell lines with high expressed sPDGFR?-Fc.The sPDGFR?-Fc can inhibit the cell proliferation significantly and it means sPDGFR?-Fc might be a new anti-cancer drug in the future.
