In this paper, water content, mineral element and active ingredient concentration on fifteen Inonotus obliquus which comes from all over the world were studied. In the aspect of water content, the free water content of Finnish birch was the highest, reaching 77.21%, significantly better than that of other strains. The free water content of JL04 is the lowest, only 54.6%. The bound water content of HLJ01 which from Heilongjiang is the highest, reaching 10. 74% , significant differences among other strains. The bound water content of Birch Russia was the lowest. In the aspect of mineral element, the calcium content of NBRC9788 was the high- est (3.49 mg · g(-1)), significantly better than other strains. The second was Finnish birch. The lowest was CX02. The phosphorus content of NBRC9788 was the highest (210.12 μg · g(-1)), significantly superior to other strains. The lowest was JL04. In the aspect of active ingredient concentration, the triterpenoids content of HLJ01 was highest (23.7 mg · g(-1)), significantly better than other strains. It was good strains for biological products research and development and then was Finnish birch. The betulin content of MAFF420165 and MAFF420308 was low, they were not suitable for production. The polysaccharide content of Finnish birch was the highest (9.7%), significantly better than the other strains, it is one of the most ideal and good strains to develop polysaccharide. The polysaccharide content from MAFF420308 and MAFF420256 was 1.2%, lower than other strains. We suggest that avoid using these strains in the study of polysaccharide product development.

OBJECTIVETo investigate serum procalcitonin (PCT) concentrations in premature infants with different gestational ages at different times after birth.

METHODSA total of 217 neonates without infection, including 102 premature infants and 115 full-term infants, were enrolled in this study. The premature infants were further divided by gestational age into three subgroups: 30-32 weeks (n=30), 33-34 weeks (n=35) and 35-36 weeks (n=37). All the infants were studied to evaluate serum PCT concentrations at 0-12, 13-24, 25-36, 37-48, 49-72, 73-96, 97-120 and 121-144 hours after birth.

RESULTSIn the newborns, serum PCT concentrations increased gradually after birth, reached peak values at about 24 hours after birth, and then gradually declined and dropped to normal values for children at about 96 hours after birth. In the premature infants, serum PCT concentrations reached peak values at about 36 hours after birth, later than in the full-term infants, then declined slowly and dropped to levels similar to the full-term infants at 96 hours after birth. Serum PCT concentrations in the 30-32 week subgroup remained at low levels after birth, and increased gradually, later than in other premature infants, at 37-48 hours after birth.

CONCLUSIONSEarly after birth, neonates have a changing serum PCT concentration, increasing first and then decreasing. Peak serum PCT levels appear later in premature infants than in full-term infants. Serum PCT concentrations of premature infants with a gestational age of under 32 weeks remain at relatively low levels within 36 hours after birth.

Objective To establish the standard operating procedures on multiple locus variable number tandem repeat analysis and to evaluate the values in identification of Brucella(B.) melitensis and epidemiological trace-back.Methods Sixteen B.melitensis,22 B.abortus,21 B.suis and 10 B.cnais were investigated by Brucella MLVA-16 genotyping scheme.All data were analyzed using BioNumerics version 5.1 software (AppliedMaths,Belgium).Clustering analysis was based on the categorical coefficient and unweighted pair group method using arithmetic averages(UPGMA) method.Polymorphism at each locus was quantified using Nei's diversity index.Resultant genotypes were compared using the web-based Brucella 2010 MLVA database.Results MLVA methods were successfully established and some strains can be clustered.Bruce06,bruce08,bruce11,bruce12,bruce42,bruce43,bruce45 and bruce55 were useful for species identification of Brucella isolates.Bruce04,bruce07,bruce09,bruce16 and bruce 30 afforded a higher discriminatory power for investigation of strain relatedness in regions of endemicity.Conclusions TheMLVAmethod has proved to be highly discriminatory and epidemiological concordance and is easy for Brucellosis surveillance in province-level lab.

A strain of Flavobacterium lindanitolerans isolated from a sick child's ascites was described. The 16S rRNA gene of the strain was 100% identical to that of Flavobacterium lindanitolerans which was first identified in India in 2008. It was first described that the isolate required X factor (Hemin) for growth in the optimal conditions of 37 °C with 5% CO(2). The isolate produced indole and H(2)S. It did not present hemolytic feature on blood agar.

Objective To investigate the epidemiological characteristics and clinical prognosis of Kawasaki disease(KD) in Jilin pro-vince for recent 10 years.Methods The survey forms unified of standard KD epidemiology were used and sent to the province′s 32 hospitals above the county and city level with pediatric in-patients,in order to conduct a survey on the KD children during 10 years period from Jan.1,1999 to Dec.31,2008.SPSS 15.0 software was used to analyze the data.Results There were 93.75% of the survey forms came back.Five hundred and seventy-seven KD cases were reported from the 32 hospitals of 8 districts.The incidence of KD was of an increasing trend.It was 18 cases in 1999,while it was up to 122 cases in 2008.Male patients were 382 cases(66.2%),female patients were 195 cases(33.8%).The ratio of male and female was 1.96 to 1.The age of patients varied from 58 days to 14 years,those under 5 years of age accounted of 88.73%.Fourteen(2.4%) cases were found to have the sequelae of coronary artery disease.The ratio of male and female was 3.671.The younger the age,the higher the incidence of cardiac sequelae.The mainest cardiac sequelae was coronary artery ectasia.The time of visiting was(7.58?4.63) days after the onset.The KD children from 4 minority peoples including 50 cases accounted for 8.7%.The disease occurred all over the year,and had obvious season peak.Coronary artery lesions accounted for 63.26%.There was no death during acute pe-riod.The recurrence rate was 0.5%.Conclusions The incidence of KD in Jilin is in an increasing trend.The age and gender distribution are not exactly the same to pre-vious reports.There are two seasonal peaks including summer and winter,which is different to previous reports of domestic,United State,Japan.
