Objective To explore how the freshmen's self-efficiency influence the acute stress psychological reaction. Methods Self-efficiency, coping styles, personality were assessed by relevant questionnaires, and acute stress psychological reaction was measured by means of designing a experiment in 683 freshmen of military colleges.Results ①Freshmen with low self-efficiency had higher scores in Si,Mas,Dy,Nc(t=8.05,7.49,6.36,3.93,P<0.01)and lower scores in Do,Re,Pc(t=5.12,2.11,3.90,P<0.05 or P<0.01)than freshmen with high one.Among all factors mentioned above, Si,Dy,Pc got into regression equation. ② Freshmen with low self-efficiency had lower stress score than ones with higher self-efficiency(t=3.92,P<0.01).Freshmen's self-efficiency was positively correlated to total scale score and 3 subscale scores of the acute psychological stress reaction questionnaire(r=0.187～0.346,P<0.05,P<0.01).Conclusion Personality,coping style exerted influence on the freshmen's self-efficiency which is a mediator between stressors and acute psychological stress reaction.

The purpose of this study was to clarify the strains of E .granulosus from sheep of Xiwuqi and people of Xil-inhot in Inner Mongolia region and its genotypes .CO1 and ND1 of mitochondria gene were cloned and sequenced ,and then they were analyzed by MegAlign of DNAStar5 .0 .Results showed that the length of CO1 and ND1 gene of E .granulosus ,which were from sheep of Xiwuqi or people of Xilinhot ,were 936 bp and 895 bp ,respectively .The homology of CO1 gene sequences of E .granulosus strains from Xiwuqi and Xinjiang was 99 .3% ,while the homology of the corresponding gene sequences of E .granulosus from man of Xilinhot City and Xinjiang were 98 .6% .ND1 gene of E .granulosus of sheep from Xiwuqi and hu-man from Xilinhot were identical to ND1 gene of G1 type .All these indicated that the homology of E .granulosus from the two regions were high and the genotype were G1 type ,which provided an important basis for the determination of strains ,and it al-so had a great significance to prevent and control the disease .
