Résumé
To investigate the infection of Yersinia enterocolitica in Dengfeng City ,the strains were isolated from livestock and poultry .The strains were detected with biochemiological methods ,serological methods ,and virulence genes were detected with PCR .A total of 105 strains of Yersinia enterocolitica were classified from 1 285 stool samples ,the total isolation rate was 8 .17% .Among the total isolated strains ,17 strains were classified from dogs with a rate of 17 .35% and 35 strains from pigs with 13 .62% .Twelve strains were O ∶3 serotype (13 .48% ) ,12 strains were O ∶5(13 .48% ) ,and 14 strains were O ∶8 (15 .73% ) .Ail+ ,ystA+ ,yadA+ and virF+ accounted for 12 .36% ,and ystB+ accounted for 42 .70% .In conclusion ,the pigs and dogs were important animal hosts ,which may play the major role in humans'infection .
Résumé
Objective To evaluate the relationship between the anxiety condition and educational background of the autistic children's parents. Methods Questionnaires for the self-evaluation of anxiety were collected from the parents of 140 children with autism. Results The autistic children's mothers had significantly higher score of anxiety than the fathers (42. 73 ±8. 25) (t =6. 783,P ＜0. 05). The autistic boy's parents had significantly higher anxiety pressure than autistic girl's parents ( 51.38 ± 11.24 vs. 43.23 ± 6. 12) ( t = 4. 894,P ＜0. 05). The anxiety intensity of the autistic children's parents was negatively correlated with the parents'educational background ( F = 10. 788, P ＜ 0. 05 ). Conclusion The autistic children' s parents had certain anxiety,which is correlated with the their educational background and genders of the autistic children. It is necessary to interfere the negative mood to facilitate the treatment of the autistic children.

Objective To compare the risk factor of chilldren with autism and ordinary children during perinatal period. Methods One hundred and fourty children with autism and 82 ordinary children were reviewed by self-written general circumstance questionnaire and risk factor questionnaire. Results Viral influenza during pregnancy (x2 =15.29) ,bom suffocate( x2 =6. 04) , premature delivery (x2 =6. 48) , dystocia (x2 =2. 83) and artificial feeding ( x2 = 6. 02 ) were risk factors for children autism (P < 0. 05 ). Conclusion Childeren autism is associated with risk factors in rinatal period. Early dectecion and early prevention and treatment may improve the outcome.
