Objective To investigate the factor that related to neoplasm from the clinicopathologic character of gallbladder polyps, and identify the reciprocal effectiveness of these factors. Method Three hundred and forty-seven patients who were underwent operation with gallbladder polypoid lesions were reviewed. Results Logistic regression analysis showed, only 5 parameters were significant for the prediction of neoplastic lesions, including age of the patient (P =0.015), the number of polyps (P=0.018), the maximal diameter (P=0.000), echo property (P=0.000), as well as the position of polyps (P=0.030),of which the maximal diameter was the best one to predict the neoplasm polyps. Further analysis with HOC curve showed that 0.925 cm, the diameter of polyps, was the critical point to calculate the polyp was neoplasm or not. Conclusions Age of the patient , the number of polyps , the maximaldiameter, the position of polyps, and echo property are independent factors in predicting gallbladder neoplastic lesions. The size of the polyps is the most significant one among the factors to predict gallbladder neoplasm with its critical point of 0.925 cm.

BACKGROUND: Alzheimer disease is a senile degenerative disease of nervous system. Neuron apoptosis is regarded as one of possible reasons,and neuron culture in vitro is a common method to research the mechanism of apoptosis.OBJECTIVE: To observe the influences of nitric oxide-donor, sodium nitroprusside (SNP), on the expression of gene cpp32 in the cultured hippocarnpal neurons in vitro.DESIGN: A randomized controlled animal experiment. SETTING: Institute of Biochemistry and Molecular Biology in Guangdong Medical College.MATERIALS: The experiment was carried out in the Institute of Biochemistry and Molecular Biology, Guangdong Medical College, and newborn (＜ 24 hours) Sprague-Dawley rats were used.METHODS: The hippocampl neurons of rats were primarily cultured, and then treated with SNP of different terminal concentrations (0, 25, 50, 100,200, 400 μmol/L) for 24 hours, and the expressions of mRNA and protein were analyzed with RT-PCR and Western blot respectively. The hippocampl neurons of rats were treated with SNP of different terminal concentrations (0, 25, 50, 100, 200, 400 μmol/L) for 12 hours, and the activity of CPP32 enzyme was detected with CPP32 activity detected kit.MAIN OUTCOME MEASURES: The expressions cpp32 mRNA and CPP32 protein and activity of CPP32 were detected.RESULTS: The cpp32 mRNA expression was unchanged as the increasing dose of SNP, but the pro-CPP32 was activated and the activity of CPP32 was increased significantly at 50 μmol/L SNP which was 3.02 times of that in the control group, and reached to the maximal value at 100 μmol/L which was 3.47 times of that in the control group.CONCLUSION: SNP cannot increase the cpp32 mRNA expression, but can increase degradation of pro-CPP32 and activate CPP32.
