The feature of HPM(high-power microwave) and its effect are briefly introduced.The destroying mechanism of HPM to different electronic medical equipment is described in detail.The reinforcement of HPM and effective measures are discussed.It is crucial to study the effects of high-power microwave radiation on military electronic equipment due to wide application of HPM in future military actions.

Objective To explore the role of the medical engineering department in integration of the health care,nursing and medical technology departments.Methods The medical engineering department and integration of health care,nursing and medical technology departments were introduced from the aspects of concept,role,characteristic,working mode and etc.Results The medical engineering department contributed to enhancing medical service,medical safety and patient satisfaction,while the role needed strengthening.Conclusion Some measures are put forward to the medical engineering department during integration of health care,nursing and medical technology departments from the aspects of department positioning,examination and assessment,management mode and etc.

The necessity to apply medical devices properly was introduced, and the present situation of the application of hospital medical devices were discussed from the aspects of overuse, abuse, operation and supervision. Some countermeasures were put forward to solve the problems in the application of hospital medical devices. It's pointed out that the application of hospital medical devices tends to be standardized with the progress of medical reformation, the attention on medical devices management, the supervision and etc.

Wearable health monitoring systems that use wearable biosensors capturing human motion and physiological parameters, to achieve the wearer's movement and health management needs. Wearable health monitoring system is a noninvasive continuous detection of human physiological information, data wireless transmission and real-time processing capabilities of integrated system, can satisfy physiological condition monitoring under the condition of low physiological and psychological load. This paper first describes the wearable health monitoring system structure and the relevant technology applied to wearable health monitoring system, and focuses on the current research work what we have done associated with wearable monitoring that wearable respiration and ECG acquisition and construction of electric multi-parameter body area network. Finally, the wearable monitoring system for the future development direction is put forward a simple expectation.

Objective To explore the establishment and application of a centralized purchase and distribution mode for medical instruments.Methods The centralized purchase and distribution mode was constructed based on the professional distributor and logistics team,and the application of medical instruments intra-hospital supply,processing and distribution (SPD) system was analyzed in the centralized purchase.Results Centralized purchase and distribution enhanced management efficiency and decreased inventory cost,and SPD system simplified the distribution mode and increased transport efficacy.Conclusion It's pointed out that professional logistics services be introduced to assist hospitals in centralized purchase and distribution.

Objective To observe the changes of cerebral blood flow velocities and carbon dioxide (CO_2) reactivity of cerebral vessels in children after cardiopulmonary resuscitation,and the relationship between the changes of cerebral blood flow and outcome.Methods The waveforms,cerebral blood flow velocities of left middle cerebral artery and extracranial internal carotid artery were monitored by Transcranial Doppler (TCD) in 35 post-resuscitation children. Glasgow coma score (GCS) was estimated at the same time.They were divided into three groups according to the diastolic blood flow velocities:low perfusion group,high perfusion group and near-normal perfusion group.CO_2 reactivity of cerebral vessels was induced by hyperventilation in 26 children under ventilation.Results In both low and high perfusion groups,GCS and CO_2 reactivity of cerebral vessels were significantly lower than that of near-normal perfusion group (P＜0.05);the numbers of died and withdrawing treatment patients were significantly higher than that of near-normal perfusion group (P＜0.01).Conclusion TCD monitoring is a useful technique for estimating cerebral perfusion,outcome and CO_2 reactivity of cerebral vessels of children after cardiopulmonary resuscitation.A secondary ischemic event may be caused by a forced hyperventilation therapy in the condition without TCD monitoring in post-resuscitation patients.
