ABSTRACT
Objective To explore the clinicopathological characters of T2 gastric cancer and the value of MSCT in the preop‐erative TNM staging of T2 gastric cancer .Methods A total of 93 patients with T2 gastric cancer were included in our study and un‐derwent preoperative MSCT staging ,who were confirmed by pathologic results .Then the results were compared with those of path‐ologic TNM staging .Also the clinicopathological features of the T2 gastric cancer were analyzed .Results There were no statistical‐ly significant differences in the clinicopathological characters among T2a and T2b patients (P>0 .05) .Comparing with pathologic TNM stage ,the T staging accuracy of MSCT was 91 .40% (85/93) ,the N staging accuracies of CT was 66 .67% (62/93) ,in which , 68 .18% (30/44) ,65 .00% (26/40) ,60 .00% (3/5) and 75 .00% (3/4) were for pN0 ,pN1 ,pN2 and pN3 .And the TNM staging ac‐curacies of CT was 67 .74% (63/93) ,in which ,68 .18% (30/44) ,64 .10% (25/39) ,60 .00% (3/5) and 100% (5/5) were for stageⅠ ,Ⅱ ,Ⅲ and Ⅳ .Conclusion There are no significant different on clinicopathology features among T2a and T2b patients .MSCT can clearly determine the preoperative TNM staging of T2 gastric cancer .
ABSTRACT
14 hybridoma cell lines were established by fusing spleen cells of BALB/c mouse immunized with BPO_(21)-BSA with SP2/o myeloma cells. Fusing rates are 100% and antibody secreing positive rate are 14.5% and 16.7% and followed by cloning the positive rate incresing to 100% were obtained. 14 hybridoma cell lines prepared ascites that were positive at 8?10~7-2.6?10~7 respectively as measured by ELISA method, the specific of antibodies were proved by ELISA and inhibition ELISA method with BPO23-HSA. The chromosome number of these 6 hybridomas cell are 98 to 115.One out of 14 hybridomas cell line is IgG2b, the others are belong to IgG1. These kinds of anti-penicilloyl group antibodies will be used to detecting the allergen in penicillin preparation.
