Objective To provide theoretical and scientific evidences for plague control,through understanding the F1 antibody level distribution and affected factor of population having healed from plague from plague natural focus of Rat.flavipectus in Yunnan Province.Methods The places and population investigated were chosen according to plague surveillant data in Yunnan Province from 1986 to 2005,using caso-control study and quesfionary. All samples were detected by indirect hemagghtination(IHA),including 248 serum samples from population having heaIed from phsue in 23 counties as case group.295 senlm samples from healthy population inoculated with EV vaccine in 7 counties as artificial immunization group, and 235 serum samples from healthy population not inoculated it in a non-plagued foei county as negative comparison group,with the diagnosing standard for positive titor being not less than 1:20.Results(①The difference WSS statistically significant(X2=44.80,P<0.05)between plague and non-plagued foci with F1 antibody positive rates being 22.10%(120/543)and 0(0/235),respectively.② The F1 antibodv positive rate of case group,35.89%(89/248)and geometric mean titer(GMT)1:84,was higher than that of artiIicial immunization group,which was 10.51%(31/295)and with GMT 1:34,respectively,the difference being statistically significant(X2=50.41,P<0.0125);the positive rate of case group wgs hisher than the neganve comparison group,the difference being statistically significant(X2=103.39,P<0.0125):the posifive mte of artificial immunization group was higher than the negative comparison group,the difference being statisticallv significant(X2=26.23,P<0.0125).③The differences were not statistically significant in the F1 antibedy positive rates of case group for age,sex,nation and occupation(X2=1.88,2.01,5.46,0.04,P>0.05).④The difference was not statistically significant in 89 plague patients with positive F1 antibody at the time of onset and rehabilitation(t= 1.23,P>0.05).Conclusions ①Plague FI antibody in people distributes the sanle a8 the plague natural focus of Rat.flavipectus does in Yunnan Province.②For naturally infected plague patients,only 1/3 popuhtion get long- term immunity,and still 2/3 can be infected again.The protecting rate and effect of naturally acquired immunity due to infection of plague are better than amfieially acquired immunity from inoculation of EV vaccine.③For the population having healed from plague,the positive rotes of FI antibody are not affected by age,sex,nation and occupation,however for those whose plague F1 antibody is still positive after some time,the titer will remain or even increase.

Objective To analyze the species of the antibody and immune responsibility in pneumonic plague patients in order to pave the way to screen the new sub-unit of the vaccine to provide the experimental basis. Methods Using the virulence-related protein microarray containing 149 proteins of Yersinia pestis (Y.pestis), the species of the antibody and immune responsibility were analyzed in serum of two pneumonic plague patients in six months after onset. Results Eighty-eight gene coded proteins were detected out the related antibodies except YPMT1.23c, YPMT1.86, YPO0406 and YPO1071 in patient 1. Forty-three antibodies from gene coded protein were analyzed, other forty-nine had not been identified in patient 2. Thirty-nine antibodies were detected in both patients. The proteins YPMT1.81c, YPMT1.84, YPCD1.31c, rw10, YPCD1.28, YPCD1.58, YPMT1.62c, YPO3247-related antibodies increased significantly by 109.96,176.4 ;20.64,17.73 ;16.50,7.16 ;23.51,7.65 ;46.00,25.61 ;4.50,8.24 ;5.98,5.08 ;23.98,4.76 folds, respectively. Conclusions The study on the antibody in pneumonic plague patients helps us to select the potential vaccine candidates, which reveals that eight proteins are the immunity diagnosis targets and the research key of sub-unit vaccine.

Objective To study the molecular genetic background of Bel subtype at ABO blood group.Methods Three samples and fifteen samples were diagnosed as Bel subgroup and normal control samples by serological test,respectively.The extracted DNA was genotyped by sequence specific primer- polymerase chain reaction foilowed by sequencing for Exon6 and exon7 at ABO locus and clones were sequenced.Results A novel Bel variant allele(GenBank EF117687) was identified in a Bel individual.The Bel allele was different from the regular B101 allele by single 952G>A missense mutation in exon7.resulting in an amino acid subsfitution of Val for Met at 318 locus.No mutations were detected in the fifteen control samples and the other two Bel allele samples.Conclusions The mutation position was fimt found to lie on coding region of ABO gene behind nucleotide 930.The mutation of G952A in the al,3 galactosyhransferase gene may be one of the molecular genetic basis of Bel ohenotype.

Objective To investigate serological blood typing of the ABO locus which contradict to general law of inheritance in parentage,and the underlying reasons for severe hemolytic disease of newborn(HDN).Methods To research the family whose newborn is AB phenotypes,mother is O phenotypes and father is AB phenotypes.The familiy were genotyped by parentage tests, serological tests,PCR-SSP and direct DNA sequencing at exons 6 and 7 of ABO gene.At the salne time,HDN was detected by micro column gel Coombs (MGCT), and the primary fingerposts of the routine blood tests. Biochemical tests were dynamically observed.Results The results of parentage tests showed that three-generation pedigree have parent-child relationship. The red blood cell(RBC)of this AB phenotypes of this family members strongly agglutinated(4+)with diverse monoelonal anti-A and anti-B antibodies,and their serum did not contain anti-A and anti-B antibodies in blood anti-typing.PCR-SSP can not detect their A and B gene,but DNA sequencing at exons6 and 7 of ABO gene revealed that it had the B(A)803C→G mutation.Conclusions The genetm basis of this parentage are B(A)803G blood gene which harbored both A and B difunctionality of glyeosyhransferases.This was the first report that severe HDN resulting from a large number of A and B antigens in RBC of B(A)phenotype of a newborn,which has clinical significance on ABO locus.

Objective To explore the role and clinical significance of interleukin-6(IL-6) in children with bronchial asthma.Methods Sera were collected from 29 cases with asthmatic attacks,32 asthmatic children who in stable conditions,and 20 health children.Serum IL-6 concentrations were measured by radioimmunoassay(RIA).Results 1.Asthmatic children appeared significantly higher levels of serum IL-6 during asthmatic attacks as compared to those in stable conditions and healthy ones respectively(P3 years old had significantly higher serum IL6 concentrations than ≤3 years old children in remission.Conclusion IL-6 may participate pathogenesis of asthma,and it may play different biological roles during asthmatic attacksas or stable conditions.
