Objective To study wrong diagnosis in the patients with epidemic hemorrhage fever in the early stage. Method To analyze the data such as the time of making wrong diagnosis,the wrong diagnosis,the department of treatment and the hospital of treatment before the diagnosis was made and the relationship between the clinical type and making wrong diagnosis. Results Making wrong diagnosis in the patients with epidemic hemorrhage fever was common (88.97%),and it was more happened in the early stage,in the non-typical and mild patients and in the lower grade hospitals.The wrong diagnosis rate (28.95%,11/38)was lower in the Infectious disease department than in the other department (93.65%),P

Objective To explore the expression of early growth response gene-1 (EGR-1) in T cells that were positive for Tax protein of human T-cell leukemia virus type 1 (HTLV-1) and its possible reg-ulatory mechanism .Methods A series of expression structures carrying the regulatory elements of EGR-1 in different length and luciferase reporter genes were constructed .TaxP cells were transfected with the con-structs containing reporter genes and cultured with 5μmol/L of NF-κB inhibitor BAY 11-7082 or equal vol-ume of DMSO.After cultured for 24 hours the cells were collected to test the luciferase activity .BAY 11-7082 or equal volume of DMSO was added into the supernatant of TaxP cell culture to test the expression of EGR-1 protein by Western blot after 24 hours of culture .Tax and its mutants M22 and M47 were transfected into 293 T cells respectively to test the expression of EGR-1 protein by Western blot after 24 hours of culture . Results The expression structures carrying the regulatory elements of EGR-1 in different length and their mutants followed by luciferase reporter genes were successfully constructed .The luciferase activity in the cells transfected with the constructs containing the elements E 1 and E2 were higher than that transfected with E3, DelE and MutE, but the reporter gene expressions were decreased with the interference of BAY 11-7082 (P<0.01).However, there were no significant changes with the luciferase activity in the cells transfected by elements E3, DelE and MutE.Western blot analysis indicated that the expression of EGR-1 protein was significantly decreased with the interference of BAY 10-7082 .The expression of EGR-1 protein in M22 mu-tants-transfected 293 T cells were decreased significantly in comparison with those by wild type tax-and M47-transfected cells .Conclusion NF-κB was the key nuclear factor in regulating the expression of EGR-1 pro-tein in Tax-positive T cells .
