Objective:To investigate the effects of IP10(IFN-? inducible protein 10,CXCL10) on anti-tumor immune response and to explore its mechanisms involved in.Methods:A mammary carcinoma cell line 4T1 was transfected with pcDNA3-IP10(IP10-4T1) by electrophoration and positive clones were screened in the presence of G418.Growth kinetics of IP10-4T1 cells was observed in vitro and in vivo.Survival rate among the animals was determined by daily assessment.Proliferation activity of lymphocytes was analyzed with()~3H-TdR incorporation.The phenotypes of lymphocytes isolated from tumors by ficoll density gradient centrifugation were assayed by flow cytometry.Results:The growth rate of IP10-4T1 cells was similar with that of parental 4T1 cells and neo-vector transfected 4T1 cells in vitro.Growth of the tumors formed by IP10-4T1 cells was inhibited in vivo.Compared to those of controls,the size and the weight of the tumors formed by IP10-4T1 cells decreased significantly 35 days post tumor transplantation(P

Objective To evaluate early dynamic contrast enhancement CT on multiple organ failure in acute pancreatitis.Methods 333 cases of acute pancreatitis identified by clinical and early dynamic contrast enhancement CT were collected.Patients were divided into organ failure group(OF group,124 cases) and non-organ failure group (notn-OF group,209 cases).All variables including duration of hospitalization,need for intensive care unit,infection,need for operation,mortality and MCTSI,EPIC score were analyzed by U test and x2 test firstly.The variables with significance (P＜0.05) were analyzed by Stepwise Logistic regression further.Results On U test and x2 test,there were significant differences(P＜0.001) between two groups in duration of hospitalization,need for intensive care unit,infection,need for operation,mortality,MCTSI score and EPIC score and APFC + ANC＞ 100 mL,and bilateral pleural effusion/ pulmonary atelectasis.The Stepwise Logistic regression analysis demonstrated that increased MCTSI and EPIC score,APFC+ANC＞ 100 mL and bilateral pleural effusion/pulmonary atelectasis were 4 independent risk factors of multiple organ failure in acute pancreatitis.Conclusion Multiple organ failure in acute pancreatitis can be judged with early dynamic contrast enhancement CT for improved treatment.
