ABSTRACT
Objective To investigate the effect of tuftsin and its inhibitor on pancreas microcirculation in acute pancreatitis(AP). Methods Sprague Dawley (SD) rats were randomly divided into five groups. Murine AP model was produced by retrograde injection of 4% sodium taurocholate into pancreatic duct, tuftsin or its inhibitor was injected at a dosage of 75 ?g/kg. At the time of 0,3, 6, 12 h, pancreas was harvested for pathology of microthrombus. esults Microthrombus in control group was not different with that in tuftsin group; At the time of 3、6 and 12 h microthrombus in other 3 groups significantly increased than control group and tuftsin group; With time, microthrombus in AP group、AP+ tuftsin group and AP+inhibitor group increased steadily and statistically significant; Tuftsin inhibitor significantly decreased microthrombus at the time of 6、12 h.Conclusions In acute pancreatitis tuftsin deteriorated pancreas microcirculation, which could be partially reversed by the administration of tuftsin inhibitor.
ABSTRACT
Objective To determine the effective prognostic parameter and the best prognostic index of gastiric carcinoma.Methods The prognostic relevance of clinical and pathological variables were evaluated in 83 patients with histologically proved stomach carcinoma (including the expression of nm23, c erbB2, microbloodvessel and PTNM) by the multivariate analysis of COX regression.Result PTNM staging was the only parameter to enter the COX model.Conclusion The PTNM staging is the most important, reliable and best varible factor in predicting the clinical outcome of stomach cancer.
