OBJECTIVE To understand the current situation in management of nosocomial infections in hospitals,and provide rational preventive measures in order to improve the medical care quality.METHODS An observatory study was conducted and reasonable suggestions were preferred referring to foreign nosocomial infections modes.RESULTS Problems were found to a different extent in administration of nosocomial infections.Most alarming problems were shortages of rules and regulations,and deficiency of infection propaganda and administration coordination.CONCLUSIONS Strengthening management of nosocomial infections is one of the key issues for improvement of the medical care quality and should be paid special attention.

ObjectiveTo investigate the mentation of the female in mammography examination. Methods292 female patients (over 35 years old) from the out-patient department accepted the psychological questionnaire survey.ResultsMost female patients showed some mental problems, include angst, discomposure, tension or funk for examination. They worried about examination result and the damage being exposed to the X-ray irradiation.ConclusionTechnicians should pay attention to the mentation of the female in mammography examination to win their trust and cooperation.

Mild cognitive impairment caused by craniocerebral trauma is the key points and difficulties in judicial authentication. This article has comparative analysis of each mode of event-related potential (classical Oddball, Eriksen flanker task and so on), which can provide a more objective method for such craniocerebral trauma cases in clinical forensic judicial authentication.

Objective To study the inhibitory effect of radicamine A on ?-glucosidase and the glucose's absorption by small intestine.Methods Inhibitory effect of radicamine A was studied both in ?-glucosidase inhibition experiments and by a valgus cyst model of small in testine in vitro.Results Radicamine A inhibited ?-glucosidase and glucose's absorption in a dose-dependent manner(P

Objective To explore the feasibility of 7.0T MR scanner in mouse aorta atherosclerosis models.Visualising the TN-C in atherosclerotic plaque by immunohistochemistry and its correlation with CD68 to provide experimental basis for the feasibility of TN-C in targeted MRI.Methods ApoE-/- mice and wild type C57 mice were fed on high fat diet to establish aorta atherosclerosis model (n=10),the aorta were observed by MRI after 14 weeks.The aorta specimens were taken to stain with HE to observe the pathological changes.The plaque was stained with oil red O,anti-TNC and TN-C antibody respectively to observe the fat,CD68 and TN-C in plaque.Results 7.0 MRI showed the aortic wall of the experimental group was thicker,high signal on T1 WI and PDWI,and low signal on T2 WI after 14 weeks.The histopathlogic examination showed the intima was obviously thicker,and the lumen was ir-regulary narrow.Both of CD68 and TN-C were highly expressed in plaque,and the distribution of TN-C correlated with CD68.In the control group,no case showed hyper-signal in the vessel wall of aorta or narrow lumen by MRI,and the histopathlogy showed no for-mation of atherosclerotic plaque in the aorta.Conclusion Aorta atherosclerotic plaque can be established through high fat diet on ApoE-/- mouse,and 7.0 MR can successfully detect it.TN-C is high expressed in AS plaque and the expression is correlated with CD68,which may suggest that they may collaborate in the development of AS.Detecting TN-C could be useful for the further study of atherosclerotic plaque.
