医院信息系统安全保障策略探析

随着医院信息化建设的不断发展,如何建立一套科学有效的信息系统安全策略,保障医院信息系统安全、可靠、高效地运行。已成为当前医院信息化建设中亟待解决的问题。针对医院信息系统中存在的安全隐患,从硬件与软件两个方面进行了系统的分析与探讨,提出一套行之有效的安全保障策略,对提高医院信息系统的安全性和可靠性具有一定指导意义。     

亓鲁光教授同病异治糖尿病经验

亓鲁光教授认为,古时消渴三消辨证,目前已很难满足现代临床诊治糖尿病的需要,临床辨证应大胆地突破三消辨证,应辨证辨病相结合,同病异治,异证求同,中西医结合,尤重固本化瘀疏肝之法,综合改善胰岛功能,平稳降低血糖。     

肠内营养膳食治疗信息系统的组成与特点

数字病案系统的功能与应用

数字病案系统是一个先进的数字化病案管理系统,包括服务器端管理子系统和客户端查询子系统,实现病案检索、查询、审批、阅览、统计、打印等功能的网络化、自动化管理和应用。该系统采用病案原件同步扫描和缩微的技术,既实现了病案的数字化应用,又保存了病案的法律载体。     

人文关怀在健康体检工作中的应用

目的对医院体检中实施人文关怀和规范化礼仪服务的效果进行评价。方法统计2004--2005年体检的接待、导检服务、体检结果的分析与指导等情况，在体检人数、体检环境设施、医护服务态度、护士仪容仪表、体检技术水平、沟通交流能力、健康知识宣教等方面，对传统门诊方式体检和规范化礼仪服务体检所产生的体检者满意度进行对比分析。结果在体检中实施人文关怀和规范化礼仪服务后，受检人员对医务人员服务各项指标评价的满意度均有明显上升。结论健康体检中实施人文关怀有助于提高医护人员的整体素质和服务质量，具有实际应用意义。     

血糖控制水平对高血压糖尿病合并脑出血患者并发症的影响

目的探讨血糖控制水平对高血压糖尿病(diabetes mellitus,DM)合并脑出血患者并发症发生的影响。方法将156例脑出血患者按血糖控制水平分为DM血糖控制良好组(95例)和DM血糖控制不良组(61例),比较两组患者死亡率和并发症的发生情况。结果 DM血糖控制不良组患者肺部感染、压疮的发生率及死亡率高于DM血糖控制良好组,两组比较,差异具有统计学意义(均P<0.05)。结论血糖控制不良会增加高血压糖尿病合并脑出血患者死亡率及肺部感染和压疮的发生率。加强血糖的监测与控制,做好患者和家属的健康指导,对降低并发症的发生具有重要意义。

双探头符合线路SPECT正电子显像衰减校正实验研究

Objective The photons from the body would be attenuated in their intensity by the soft tissue before they reach the detectors. Some of them lost more intensity than others when coming from the deeper body. Attenuation of the photons would distort the image, affect the image quality, and may lead to misdiagnosis. In this research the X-ray and γ-ray were used as transmission resources for accurate assess-ment of attenuation in each part of the body. The transmission data was used to correct the emission data from the body. Iteration algorithm was used for the reconstruction of attenuation corrected tomography ima-ges. Evaluate the efficacy of attenuation correction in duel head hybrid SPECT/coincidence PET systems (SPECT/PET) and SPECT using both the Jaszczak and the myocardial phantoms. Methods For PET phantom study, the Jaszczak phantom was filled with the aqueous solution of 18F-fluorodeoxyglucose (FDG) and was scanned with two hybrid SPECT/coincidence PET systems respectively (Vertex Plus, Netherlands Philips ADAC Company and Hawkeye, USA GE Company). The PET images were acquired and reconstruc-ted. Results The "cold" lesion, which the diameter was less than 12 mm of uncorrected image, could not be identified. But it, after correction, diameter 9 mm, would be recognized clearly, less than 7 mm would not be distinguished. Noncorrected image could only identify "hot" lesions which the diameter were 9, 12, 14, 18, 22 and 38 mm, while in the corrected image, not only it was much better, but also the "hot" le-sion of 6 mm was distinguished. In Hawkeye, the same situation, the corrected image of was improved obvi-ously; the disparity of counts between surrounding and deep center less, and the counts in deep center were compensated. There were only 3 round " cold" lesions could be recognized, the diameter: 14, 18 and 20 mm; all of them which diameter were less than 12 mm could not be distinguished. One in the center was al-most as background, and could not be identified. The radioactive accounts of surrounding and center were quite different. The corrected image 5 "cold" lesions could be found, 9, 12, 14, 18 and 20 mm, but7 mm could not be found. The noncorrected image, only 12, 14, 18, 22 and 38 mm " hot" lesions could be found, and by the surrounding, there was an arc shape "hot" lesion. But it could distinguish 9, 12, 14, 18, 22 and 38 mm "hot" lesions on the corrected image, and the image was much better than noncorrected one. Conclusions The corrected image of Vertex Plus was improved obviously with the disparity of counts between surrounding and deep center less, and the counts in deep center was compensated. The result of at-tenuation with phantom showed that 137Cs was better than CT in both image quality and spatial resolution.
