Objective To analyse the operation technique and therapeutic effect of "inserting" uretero-intestinal anastomosis in orthotopic bladder substitution.Methods Thirty-eight patients undergoing orthotopic bladder substitution operations were followed up,and the way of uretero-intestinal anastomosis in all Datients was the "inserting"uretero-intestinal anastomosis.The therapeutic effect was observed by radiation,cystoscopy,pathologic biopsy and blood test.Results The average follow-up time was(3 1.65±14.14)montll8.and the stricture rate was 4%(3/75),but no vesicoureteric reflux was found.The rate of leakage was 0.Nipples were formed at the site of anastomosis under the view of cystoscope,and among the 7 patients whose nipples were taken to be examined by histology,2 cases were intestinal epithelium which were taken at the base of nipple8.while the others were transitional epithelium which were taken at the top of nipples.The renal function of all patients was normal (Cr 54-135 μmol/L,BUN 3.2-9.4 mmol/L).Conclusion "Inserting"uretem-intestinal anastomosis is an ideal antireflux uretero-intestinal anastomosis method.

Objective To assess the sensitivity and specificity of vaginitis pathogen detection reagent kit (Nucleic acid hybridization). Methods Four hundreds cases of vaginal secretion samples were detected with Amsel, vaginalis culture, fungal culture and Affirm VPIII detection method, respectively. Using the methods of Amsel, vaginalis culture and fungal culture as the gold standard, the clinical application value of Affirm VPIII detection method was evaluated. Results Compared with Amsel, the sensitivity and specificity of Affirm VPIII detection was 92.2%and 70.5%, respectively. Compared with fungal culture, the sensitivity and specificity was 88.3% and 92.9%, respectively. Compared with vaginalis culture, the sensitivity and specificity was 92.6% and 93.8%, respectively. There was a good consistency between the gold stardard and the Affirm VPIII detection. Conclusion Compared with the traditional detection methods,the Affirm VPIII detection has the advantages of fast detection speed,simple operation, and high sensitivity and specificity. In addition, it can identify three kinds of vaginitis pathogenic microorganisms at the same time,with a certain clinical value.

Objective:To investigate the correlations of Lauren classification and world health organization (WHO) classification of gastric cancer (GC) with microvascular density (MVD), matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), vascular endothelial growth factor (VEGF), vascular endothelial growth factor receptor 1 (VEGFR1), vascular endothelial growth factor receptor 2 (VEGFR2), and p53. Methods:The clinical data of 89 patients with GC were collected. The collected specimens were categorized on the basis of Lauren classification and WHO classification. CD34/periodic acid-Schiff (PAS) double staining was performed to validate MVD. Immunohistochemistry was conducted to investigate the expression levels of MMP-2, MMP-9, VEGF, VEGFR1, VEGFR2, and p53. Results:MVD was not correlated with Lauren classification or WHO classification (P>0.05). Lauren typing was associated with the expression levels of MMP-9, VEGFR1, and p53 (P<0.05). WHO classification was not related to any of the factors (P>0.05). Cox proportional hazards model revealed that Lauren classification and WHO classification were the prognostic factors of overall survival (P<0.05). Conclusion:This research on tumor related factors, angiogenesis, and different classifications of GC may provide new methods to treat this disease.
