ABSTRACT
Objective To explore the data accuracy acquired by the anesthesia information management system.Methods Totally 100 patients from two hospitals were selected randomly,whose anesthesia time was estimated more than 1 h.The vital signs data acquired by the system were compared with those by the monitor once every 5 min±30 s,and totally there were 12 times of comparison executed.SAS 9.2 software was used for statistical analysis.Results In FAS set the system had the total data accuracy being 100％,95％ credibility interval from 86.87％ to 97.30％ and the BMDL higher than 85％;in PPS set he total data accuracy was 100％,95％ credibility interval was from 92.89％ to 100％ and the BMDL was also higher than 85％.The system gained "Excellent" or "Good" grade in system response,stability,functional interface operability and the accuracy of special functions.Conclusion The system acquires and stores the vital signs data automatically and accurately,enhances anesthesia information in objectivity,authenticity and tractability,and has high values for enhancing anesthesia safety,medical safety and scientific research.

ABSTRACT
Objective To establish an experimental model of acute cerebral schistosomiasis japonica and explore the MRI manifestations of acute cerebral schistosomiasis. Methods Rabbits were divided into 3 groups with 10 rabbits in each group. The rabbits in the experimental group were directly injected with suspension fluid of Schistosoma japonicum eggs(0.9 mg,1 ml) by the cranial drilling method,those in the negative control group were given saline(1 ml)by the same method above-men-tioned,and those in the blank control group were not given any treatment. Antibiotic was given to the first two groups after the op-eration. The clinical manifestations of the 3 groups were observed,and the magnetic resonance imaging(MRI)was performed in 30 days post-operation,and then the brain tissues were taken for pathological examinations. Results All the rabbits in the ex-perimental group exhibited inappetence,various neurological symptoms including hemiplegia,and weight loss after the opera-tion;while those in the negative control group showed inappetence in 3 days after the operation,and 1 week later,the symptom disappeared;there were no adverse reactions in the blank control group. MRI of the experimental group showed nodular or patchy enhancement on T1WI enhancement,brain edema,abnormal ventricular dilatation,and needle augmentation. SWI dis-played hypointense in the abnormal enhanced nodules and flaky hypointense on the operation brain. In the negative control group,2 rabbits showed abnormal enhancement of the needle canal,and 1 showed mild dilatation of the ventricle. The blank control group showed normal manifestations. The pathological examinations showed abnormal appearances in 10 rabbits of the ex-perimental group,including 6 with S. japonicum egg granuloma nodules,nonspecific granuloma nodules coexisted with perivas-cular inflammation;no granuloma nodules were found in the negative control group,but 2 rabbits showed vascular inflamma-tion;the blank control group showed the normal brain tissue. Conclusions An experimental model of acute cerebral schistoso-miasis is successfully established in rabbits by intracranial injection of schistosome eggs. The MRI examination combined with the clinical manifestations can improve the accuracy of early diagnosis of cerebral schistosomiasis.
