To explore the expression and function of MG 7 Ag on gastric cancer cell line SGC7901 and its drug resistant subline,SGC7901/VCR, with different resistance index (0 3, 0 7, 1 0) The expression of MG 7 Ag on SGC7901 and SGC7901/VCR cells was determined by immunohistochemical method and flow cytometry (FCM) MTT assay was used to explore the effects of monoclonal antibody MG 7 on drug sensitivity of gastric cancer cells FCM was used to explore the effects of MG 7 on adriamicine accumulation of SGC7901/VCR cells SGC7901/VCR cells exhibit increasing positive staining of MG 7 than SGC7901, according to the increasing resistance index Sensitivity of vincristine of both SGC7901 and SGC7901/VCR cells was reduced after being treated with MG 7 And SGC7901/VCR cells showed decreased adriamicine accumulation when they were incubated with MG 7 Therefore, the conclusion is that MG 7 Ag may be a novel molecule associated with multidrug resistance of gastric cancer, and play an important role in maintaining the drug resistant phenotype of SGC7901/VCR cells.

Objective We sought to determine the incidence,clinical features,and risk factors for retroperitoneal hematoma(RPH)after percutaneous coronary intervention(PCI).Methods A retrospective analysis yielded 21 cases of RPH out of 3,729 consecutive patients undergoing PCI between January 2000 and September 2005 in Anzhen hospital.Cases were compared with a randomly selected sample of 30 control subjects without RPH.Predictors were studied using univariate and multivariate analysis.Results The incidence of RPH was 0.6%.Anemia(100%)was a most universal feature.Features of RPH included hypotension(95%),diaphoresis(57%),groin pain(48%),abdominal pain(38%)and back pain(38%).The following variables were found to be independent predictors of RPH:female gender(odds ratio OR=5.23,P
