ABSTRACT
Objective To explore a rapid, convenient and non-polluting method of collecting cerebrospinal fluid (CSF)in Sprague Dawley(SD)rats for beginners. Methods Forty-five SD rats were divided into three groups—group 1(collecting CSF through neck muscles), group 2(collecting CSF through skin directly), and group 3(collecting CSF through endorhachis). Results The successful rate of the CSF collection in the group 1 was 86.7%, group 2 was 46.7%,and group 3 is 33.3%. Conclusions The modified collection method of CSF by cisterna puncture through neck muscles in SD rats is simple,convenient,efficient and non-polluting,and is especially suitable for beginners.
ABSTRACT
The paper uses computer multimedia technology to collect and switch audio and video signals, constructs the remote High Definition ( HD) surgery demonstration system which supports live broadcast, recorded broadcast, rebroadcast and video-on-demand depending on the network communication routing technology.It introduces functions, design scheme and composition of the system and points out that the system can realize HD video transmission and video talkback between the surgery scene and the classroom.Thus, tech-nical level of clinical surgery teaching can be enhanced.
ABSTRACT
Identifying the similarity and differences of malpractice,medical negligence and medical error has realistic meaning to deal with medical disputes efficiently.They are all subjective negligence and belong to the category of medical behavior.This paper mainly discussed the criteria and civil liability of their differences.
ABSTRACT
This article presented the idea of implementation for the general hospital scientific research management information system.Based on the network and database,the scientific research management information system was constructed by analysis on the operation process of it;the information management of the scientific research management was implemented.This modern scientific research management information would improve the hospital scientific research management level.
ABSTRACT
With the aid of scientific research management information system, we established an in-formation management for the scientific research funds. The structure,function and application of the system were introduced in this paper.
ABSTRACT
Objective To investigate the risk factors of death in patients with acute stroke in the neurological intensive care unit(NICU). Methods The clinical data of 137 patients with acute stroke in the NICU were induced. The risk factors were analysed by univariate and multi-variate Logistic regression analysis.Results There were 13 risk factors including age, coma, hyperpyrexia, pulmonary disease, atrial fibrilation/cardiac dilatation, stroke history, mechanical ventilation, brain midline shift, initial serum glucose, APACHEⅡscores, feeding tube, urethral catheter and concurrent pulmonary infection which had statistical significance between the death group and survive group,by univariate analysis(P
