Large-scale medical equipment is very important for comprehensive hospitals. Fault monitoring and diagnosing technologies for large-scale medical equipment have to been available to make full use of them. This paper introduces the evolution of equipment fault diagnosis. After comparing conventional technology and intelligent one, this paper lays emphasis on the latter.

Objective To study the characteristics of hemogram and myelogram with Brucellosis patients.Methods 25 Brucellosis patients' bone marrow and peripheral blood smears were observed,at the same time a deep clinical inverstigation on the patients was conducted. Results The counts of blood cells were decreased in part pa-tients, and a typical lymphocytes were found in peripheral blood of 64% patients. The marrow proliferative activities were normal(92% ) or higher(8% ),and all patients had poisonous granules. Red cell proliferative activities were normal(68% ) or lower(32% ). The counts of megakaryocytes were normal,but the maturity of megakaryocyte was hindered. All patients' histocytes were increased at different degrees. NAP were increased. Conclusion The changes of hemogram and myelogram have clinical significance for diagnosis of Brucellosis, but primary hematologic disease with Brucellosis should be distinguished.

OBJECTIVE: To provide the clinical anatomy data in physiological condition of the lingual artery in 64-slices spiral computed tomography angiography (CTA) for clinical treatment concerning the lingual artery. METHOD: CTA examination of the carotid artery were performed on 80 adult volunteers. The 3D reconstruction images of the carotid artery with hyoid bone were obtained by using 64-slices spiral CT and image postprocessing workstation. The origin, pathway, and anatomic relations of the lingual artery in CTA were studied. The distance from the origin of the lingual artery to the bifurcation of the common carotid artery and tip of the greater horn of hyoid bone were separately measured, and the distance between the segment of the greater horn of hyoid bone of lingual artery and the middle of greater horn of hyoid bone were also measured. RESULT: The pathway of the lingual artery had high variation, but the relative position between the segment of the greater horn of hyoid bone of lingual artery and the greater horn of hyoid bone were relatively constant. The lingual artery run forward approximately parallel to the greater horn of hyoid bone into tongue (2.32 +/- 1.29) mm in the superior to the greater horn of hyoid bone or (2.00 +/- 1.68) mm in the inferior to the greater horn of hyoid bone The distances from the origin of the lingual artery to the bifurcation of the common carotid artery and tip of the greater horn of hyoid bone were (12.93 +/- 7.36) mm and (10.40 +/- 5.75) mm separately. CONCLUSION The lingual artery could be clearly shown in CTA and the anatomy data in physiological condition of the lingual artery could be obtained by CTA. There was important instructive significance for clinical treatment concerning about the lingual artery.
