The drug concentration in the blood was not associated with the retrograde amnesia, satisfaction of the patients and the convenient procedures. Conclusion: There was no significant factor to predict in advance the side

effects of the midazolam clinically, pharmacologically and genetically. Key Word(s): 1.

Methods: Retrospective analysis was performed in 1515 patients with Esophageal symptoms who painless gastroscopy in the endoscopy center from August 2010 to October 2011 by routine endoscopy, NBI and iodine staining, 101 lesions patients were screened. Of all lesions were detected by NBI with magnification and targeted biopsy. Observation analysis the incidence rate of lesions and the consistency between capillary loops (IPCL) and histological findings selleckchem were assessed.

Results: The pathologic diagnosis of all the patients showed that there were 76 esophagitis,25 early esophageal carcinoma, In appearance

of IPCL, 84% (21/25) type III and typeIV was early esophageal carcinoma, 86.3% Decitabine cost (65/76) typeII was esophagitis, and it has a relatively better consistency in IPCL with histological findings. Conclusion: There is a high detection rate in diagnosis of early squamous esophageal cancer and precancerous lesions by Lugoulp’s iodine staining and NBI endoscopy. NBI can clearly show the crypt and capillary structure of the early esophageal cancer and precancerous lesions, helps to determine depth of invasion in the esophageal carcinoma. Otherwise, NBI is assist in the selection of appropriate treatment options. Key Word(s): 1.

Several factors influence bowel preparation quality. Recent studies have indicated that the time interval between bowel preparation and the start of colonoscopy is also important in determining bowel preparation quality.
