Objective To report the diagnosis and treatment of an imported case of schistosomiasis haematobium,including the pathological features of the disease and therapeutic efficacy of praziquantel. Methods The data of the patient with schistoso?miasis haematobium were collected,and the pathological features of the bladder tissue were observed under a microscope. More?over,the patient was treated with praziquantel,and his urine was collected before and after the treatment. The eggs in the urine were examined by a microscope after sediment and the miracidia were hatched. Results The patient once worked in Angola for three months,and after returning home he had the symptoms of intermittent painless terminal hematuresis. It was ineffective af?ter anti?inflammatory treatment in a number of hospitals. There were no sand spots discovered under the cystoscope. However , the inflammatory reaction to parasite with a lot of eosinophils infiltration in the bladder mucosa was found on the pathological sec?tions under a microscope,and the egg structure was observed with individual characteristics. The eggs were detected in the urine and the miracidia were hatched before the praziquantel treatment. The hematuria symptoms disappeared after the praziquantel treatment. The eggs were still detected in the urine 7 days post?treatment,but the miracidium could not be hatched. One month and 6 months post?treatment,the eggs were not detected in the urine. Conclusions The imported cases of schistosomiasis hae?matobium are often misdiagnosed,and therefore,it is necessary to strength the health education to the workers overseas and also to improve the ability of diagnosis in medical staff. For the case reported in this paper,there are typical structure of Schistosoma haematobium eggs and egg?granulomas on the pathological sections of bladder tissues. Praziquantel has satisfactory treatment re?sults.

OBJECTIVE:To provide reference for further formulation of the rational use of vancomycin. METHODS:Retro-spective analysis was conducted on the related information of discharged patients who intravenously used vancomycin from Jun. 2013 to Dec. 2014. RESULTS:178 patients were enrolled,with average age of 59.6 and 73.60% male,who were mainly with lung infectious(74.72%). Support examinations were sufficient before using of vancomycin. 66.29% patients were empirically giv-en vancomycin with pathogenic detection rate of 85.39%. 71.91% patients were conducted therapeutic drug monitoring with only 47.54% of first blood samples achieved the target range. CONCLUSIONS:Vancomycin application is generally rational in our hos-pital. However,issues like duration of empirical therapy,rational therapeutic monitoring,and individualized start dosing still need to be noticed.

Objective In order to improve the teaching effectiveness of anatomy in nursing, this article made an exploration on the experimental teaching reform combined with the characteristics of nursing profession. Methods The nursing students of class 1and 2 of 2013were set as the research object. The class 1 (110) as experimental class, class 2 (110) for the control group. In the experimental class, the reform of teaching method and teaching quality was improved by adjusting the teaching syl-labus and teaching contents. The control class used the traditional experimental teaching method. The experiment class' teaching reform research of the human anatomy carried on the 1 semester. Exam achievement evaluation and the questionnaire survey were adopted to assess the teaching effect. SPSS 13.0 software was used to do statistical analysis and t test was used to compare two groups of students test scores, experiment grades, test scores and total scores. Results Experimental theory examination results [(47.80±7.30) vs. (44.85±8.38)], experiment grades [(15.48±1.76) vs. (14.55±2.19)], ex-periment test scores [(15.52±2.22) vs. (14.35±2.64)], total score [(78.80±8.99) vs. (73.75±10.53)] were better than control group (P<0.05). In questionnaire survey,more than 80% of the students think that the reformed teaching method can help to improve the teaching effect. Conclusion In human anatomy experiment teaching reform, the reformed experiment teaching method can significantly improve students' scores and the teaching effect. It is better than the traditional method, and is worth publicizing.
