ABSTRACT
OBJECTIVE To investigate the distribution of serum markers of transfusion-transmitted infections in hospital,and analyze the clinical values in the control of nosocomical infection. METHODS The serum markers of transfusion-transmitted infections from 21 605 hospitalized cases,such as HBsAg,anti-HCV,anti-HIV,and RPR were detected. RESULTS The positive rate of HBsAg and anti-HCV was 9.78% and 1.70%,respectively.The positive anti-HIV was detected in 13 cases by the primary screening test for HIV,and the 13 cases were reconfirmed by the reconfirmation laboratory of CDC in Hunan Province.The positive RPR was in 4 cases,the same as of TPHA.There were 2 582 positive cases of the four indexes(HBsAg,anti-HCV,anti-HIV and RPR),the total positively detectable rate was 11.95%,which was obviously higher than 7.6% of normals(P
ABSTRACT
Objective:To investigate the pathway of C.albicans-induced murine thymocyte apoptosis.Methods:The chages of TNF-? level in murine plasma and caspase-3 activity were measured by ELISA and flurorescence spectrophoto meter respectively;FCM measurement was adopted for the expression levels of related genes.Results:The level of TNF rise,the caspase-3 activity serengthen significantly and bax,p53 gene expression are upregulated.Conclusion:It is possible that C.albicans elicits apoptosis in murine thymocytes by upregulating bax and p53 gene expression as well as raising the serum TNF-? level to strenghen the activity of caspase-3.
