Objective: To verify that COX-2 promoter can drive its downstream genes specifically in COX-2-positive o-varian cancer cells; Moreover, comparing with CMV promoter, analyze the transcript efficiency of COX-2 promoter. Methods: Contacting the recombinant plasmids named COX-2-BAX and CMV-Luc. After transient transfection liposome-mediated with the plasmids COX-2-Luc and CMV-Luc, respectively, the expression of Luciferase reporter gene was measured in COX-2-positive ovarian cancer cell line-SKOV3 and COX-2-negative colon cancer cell line-SW480. SKOV-3 and SW480 were transfected with COX-2-BAX and CMV-BAX in the same way, respectively. The apoptosis rates were measured through flow cytometry. Results: The recombinant plasmids named COX-2-BAX and CMV-Luc were constructed successfully. The expression efficiency of reporter gene was 1554 ? 86. 5 in SKOV3 and 53. 7 ? 10.9 in SW480 after 24 hours transfected with phPES2, 9851. 7 ? 129. 5 in SKOV3 and 8831. 0 ? 167. 3 in SW480 after 24 hours transfected with CMV-Luc in the same way. The apoptosis rate was 10.4% in SKOV3 and 3.7% in SW480 after transfected with COX-2-BAX, 21.7%in SKOV3 and 25. 6% in SW480 after 36 hours transfected with pcDNA3-BAX in the same way.

The positive rate of autoantibodies was 29.7% in 1617 diabetic patients. The positive rate of monoautoantibody was lower than that of combined assay with 3 autoantibodies. Combined assay of multiple autoantibodies may enhance the positivity of early diagnosis of type 1 diabetes mellitus. Glutamic acid decarboxylase antibody (GADA) may be a better screening test for predicting insulin dependency, the prediction of GADA combined with protein tyrosine phosphatase antibody may approximate to 100%, whereas islet cell antibody assay may be needed in the adolescent patients.
