Objective:To analyze the management benefits of information-based management mode for medical imaging equipment,and promote rational management for equipment and improve management benefits of equipment.Methods:According to the existing information management system and electronic medical record system at Tangdu hospital,Air Force Medical University,a management platform for medical imaging equipment under information-based management mode for medical imaging equipment was constructed to manage medical imaging equipment.A total of 9 imaging equipment included magnetic resonance(MR)equipment,computed tomography(CT)equipment and X-ray equipment that were in clinical use during 2022 and 2023 were selected,and the conventional management mode was adopted to manage equipment during January and December 2022,and the information-based management mode was adopted to manage them during January and December 2023.The comprehensive management benefits of the two modes for medical imaging equipment were compared.A self-designed questionnaire was used to survey satisfaction levels of 80 patients who underwent diagnosis and treatment by using these equipment.Results:The annual examination amount,annual revenue,annual operating cost,and annual net profit of MRI,CT,and X-ray equipment of adopting information-based management mode were all higher than those of adopting conventional management mode,and the investment payback period was shorter than that of adopting conventional management mode,and the cost-effectiveness evaluation was superior to conventional management mode.The average utilization rate of equipment,rate of maintenance and upkeep,and rate of controlling risk of adopting information-based management mode were respectively(95.36±6.02)%,(92.36±4.36)%and(94.36±4.15)%,which were significantly higher than those of adopting conventional management mode(t=14.317,11.62,12.508,P<0.05).Patients'satisfactions for MRI equipment,CT equipment and X-ray equipment that adopted information-based management mode were significantly higher than these that adopted conventional management mode,and the differences were significant(x2=5.741,6.260,5.331,P<0.05).Conclusion:The information-based management mode for medical imaging equipment can real-timely obtain the situations of usage and monitoring for medical imaging equipment,and enhance cost-effectiveness and management effectiveness at the maximum extent,and enhance users'satisfaction in using medical equipment.

AIM:To investigate the effects of the γ-aminobutyric acid(GABAergic)neural pathway from the anterior cingulate cortex(ACC)to the nucleus accumbens(NAc)on the regulation of irritable bowel syndrome(IBS)and its underlying mechanisms in mice.METHODS:(1)A C57BL/6J mice model of IBS was established by using chronic acute combing stress(CACS).The mice were divided into a normal group and an IBS group(n=8).The presence of IBS-like symptoms was determined through behavioural tests,an intestinal motility test and abdominal withdrawal reflex scores.(2)Fluorescence gold(FG)retrograde tracing and immunohistochemistry were used to investigate the ACC-NAc GABAergic neural pathway and to examine the activation of GABA in the ACC in IBS mice(n=8).(3)A total of 1.5 μL of normal saline(NS),GABAA receptor antagonist bicuculline(BIC)or agonist isoguvacine hydrochloride(Isog)was ad-ministered via a preburied catheter into the NAc of mice in IBS and normal groups.The mice were randomly divided into three groups(n=8):NS group,BIC group and Isog group.IBS-like symptoms were assessed.(4)The mice were prein-jected with AAV2/9-mDlx-iCre-WPRE-pA in the ACC and AAV2/2Retro Plus-hSyn-DIO-hM3D(Gq)-eGFP-WPRE-pA in the NAc and subsequently divided into four groups(n=8):NS(intraperitoneal injection)+NS(NAc microinjection)group,NS+BIC group,clozapine N-oxide(CNO)+NS group and CNO+BIC group.The mice who received AAV2/2Retro-hSyn-DIO-hM4D(Gi)-EGFP-WPRE-pA in the NAc were randomly divided into three groups(n=8):NS+NS group,NS+BIC group and CNO+NS group.Enzyme-linked immunosorbent assay(ELISA)was employed to estimate the expression levels of histamine and 5-hydroxytryptamine(5-HT)in colon tissue,and the effects of GABAergic neural pathways from ACC to NAc on IBS were studied.RESULTS:CACS induced IBS-like symptoms in mice.The results of FG retrograde tracing combined with fluorescence immunohistochemistry showed that GABA neurons of ACC could project to NAc.The injection of BIC in the NAc was found to significantly reduce anxiety-like behaviours,diarrheal symptoms and visceral hy-persensitivity in the IBS mice(P<0.05).Chemogenetic inhibition of the ACC-NAc GABAergic neurons ameliorated IBS-like symptoms in mice(P<0.05).CONCLUSION:The GABAergic pathway of ACC-NAc might be involved in the regu-lation of IBS in mice,which may be related to the release of histamine and 5-HT in colon tissue.

Multi-parameters patient monitors are widely used in hospitals as medical device products, which have important clinical value. It expounds the core technologies of a miniature wearable multi-parameters patient monitor, and looks forward to its application prospects. In addition to traditional applications, when combined with a networked health service platforms, its applications will be greatly expanded in the context of big data and artificial intelligence technologies. The laboratory prototype of this product has been completed and has achieved the anticipative design goal.
