Objective To investigate the histochemical changes of 3?-hydroxysteroid dyhydrogenase(3?-HSD), sucinic dehydrogenase(SDH) and lipid on rat adrenal cortex in the carcinogenesis-resistance with selentum. Methods Wistar rats stomach carcinogenesis (formation of aneuploid cells in the glandular stomach mucosa) was induced by MNNG(N-methy1-N-nitroso-guanidine,20 mg/kg)gavage. The changes of the adrenal cortex were studied by histochemistry and image analysis during preventing glandular stomach cancer with selenium(0.1 mg/kg and 2.0 mg/kg) Results 1.Dietary Se inhibited the aneuploid cell formation,which induced by MNNG gavage in Wistar rat stomach; 2.The histochemical reactions of 3?-HSD and SDH were both significantly stronger in experimental group than that in normal control group in the course of the rat stomach carcinogenesis(P

Objective To study the effect of Na-2SeO-3 on experimental carcinogenesis of stomach and on p53 and p16 expression. Methods Weaning male Wistar rats were divided into four groups randomly:high selenium group(4mg/L),low selenium(2mg/L)group,experiment control group and normal control group.Wistar rat gastric cancer was induced by N-methyl-N′-nitro-N-nitrosoguanidine(MNNG,20mg/kg)given daily for 10days.Na 2SeO 3 was given by piped drinking before one week of MNNG administration.Rats were killed at the 43th week.The surface characters of gastric mucosa were observed with noked eyes.Histopathologic changes were observed by methods of HE staining and Alcian Blue Periodic acid Schiff reaction(AB-PAS).Changes of p53 and p16 were detected by SP immunohistochemical method.The immunohistochemical results were quantitatively analysed by image analysis.Statistical analysis was taken by SPSS. Results Dietary Na-2SeO-3(2mg/L,4mg/L)aggravated gastric erosion and hemorrhage and promoted intestinal metaphasia of gastric cancer (P0.05).Conclusion These results suggest that dietary Na-2SeO-3 by piped drinking might not decrease incidence of Wistar rat gastric cancer induced by MNNG.The mechanism may be associated with the mutations of p53 and abnormal expression of p16 gene.

Objective To evaluate the clinical value of fasting blood glucose (FBG) in the diagnosis of multiple organ dysfunction syndrome (MODS) caused by pulmonary infection in elderly patients with diabetes. Methods Patients over 65 years old with diabetic pulmonary infection admitted to Department of Cadres Ward of Bethune International Peace Hospital of PLA from July 2015 to December 2016 were enrolled. According to the patient's highest FBG level during pulmonary infection, all patients were divided in two groups. The cases whose FBG ≥8.83 mmol/L were served as suspicious multiple organ dysfunction syndrome in the elderly (MODSE) group, and those had FBG < 8.83 mmol/L were served as suspicious non-MODSE group. The incidence of MODSE in suspicious MODSE group and suspicious non-MODSE group was compared. The receiver operating characteristic curve (ROC) was drawn, and the clinical value of highest FBG in the diagnosis of MODSE caused by pulmonary infection in elderly patients with diabetes was assessed. Results 119 elderly patients with diabetes and pulmonary infection were enrolled in the analysis. All patients were male, with age of 76-105 years with an average of (89.41±4.16) years. Among 119 patients, 55 of them with suspected MODSE, 64 of them with suspected non-MODSE. The incidence of MODSE in suspicious MODSE group was significantly higher than that in suspicious non-MODSE group (78.2% vs. 12.5%), with statistically significant difference (χ2 = 52.108, P = 0.000). The area under the ROC curve of the highest FBG for diagnosis of MODSE was 0.895, and 95% confidence interval (95%CI) was 0.839-0.951 (P < 0.001). When using FBG ≥ 8.83 mmol/L to diagnose MODSE induced by pulmonary infection in elderly patients with diabetes, the sensitivity was 84.3% and the specificity was 82.4%. Conclusion FBG ≥ 8.83 mmol/L, as an indicator reflecting the changes of metabolic function, have a diagnostic value for MODSE caused by pulmonary infection in elderly patients with diabetes.
