Diagnostic Value of Narrow Band Imaging with Magnifying Endoscopy on Observing Pit Patterns in Gastric Mucosal Lesions LI Ya - jun, TAO Wei, YANG Li ( Department of Gastroenterology,Ningxia Medical Univisity,Yinchuan 750004) Abstract: Objective
To explore diagnositic value of narrow - band imaging with magnifying endoscopy on
morphological changes of gastric pits in gastric lesions and early gastric cancer. Methods 112 cases with local mucosal lesions including erosion,abnormal color,uplift,shallow depression and rough were recruited in this study. Patterns of gastric pits were observed with NBI - ME model and ,the lesion type was determined with reference to Tanaka. Results
Using narrow band imaging and magnifying endoscopy,the detecting rate
gastric precancerous lesions including severe intestinal metaplasia and mild - moderate dysplasia was 39. 2% ( 44 /112) and the detecting rate of early gastric cancer was ,42. 3% ( 11 /26) . Conclusion
Narrow band
imaging and magnifying endoscopy can improve the detecting rate of precancerous lesions and early gastric cancer. Key words: narrow band imaging; magnifying endoscopy; gastric pit; pathology examine; early gastric cancer

MRSA Infection among Health Care Personnel,Patients and Environment in High - risk Wards of a Hospital YANG Bao - zhong1 , DU Rong2 , WEN Yan1 , LAN Li - li1 , YU Ying - zi1 , KOU Hua - wei1 ( 1. The Affiliated Hospital of Ningxia Medical University,Yinchuan 750004; 2. Yinchuan Maternity and Child Care Center,Yinchuan 750001) Abstract: Objective
To understand the status of MRSA carrying among health care workers and patients,
and the environment in high - risk wards of a hospital and to explore prevention and control strategies of nosocomial MRSA infection. Methods
Samples from the medical staff,the patients and environment in 7 high -
risk wards of a hospital,were cultured. MRSA strains were identified by the CLSI standarded cefoxitin ( FOX) KB method. Results
In samples from 713 health care workers and the environment,41 ( 5. 75% ) strains of
SA were found including MRSA 11 strains( 26. 83% ) . In samples from 639 patients and the environment,the detection rate of SA were 10. 49% including 43 strains of MRSA( 64. 18% ) . Conclusion
It is critical to a-
ware the situation of MRSA carrying in medical staff,patients and ward environment. We should improve hand hygiene compliance,strict implementation of sterile operating procedures and strengthen the management and training of cleaning staff to ensure effective environmental cleaning and disinfection. Key words: MRSA; health care workers; bacterial contamination
