Chinese Journal of Hospital Administration 1996;0(01):-
The hospital the authors work with succeeded in achieving three sublimations of the idea of hospital management control in the course of hospital management control innovation, viz. sublimations from one-sided development concept to scientific development concept, from people-oriented management of human resources to ability-oriented management of human resources, and from emphasizing comprehensive strength to stressing developmental ability in hospital accreditation.

Objective To evaluate MR imaging diagnosis in acute suppurative osteomyelitis at early stage. Methods The axis, sagittal and coronal planes were performed with Philips 0.5 T superconduct MR scanner on 12 cases of acute suppurative osteomyelitis in lower extremity proved by clinical data 2 to 14 days after onset. Results Abnormal signals in marrow were displayed in all 11 cases 3 to 14 days after onset. No abnormality was found in 1 case 2 days after onset. The interface between normal and abnormal marrow became clear as time going on. The lesion presented as patchy low intensity on T 1WI and high signal on T 2WI. The signal changes were marked especially on STIR. Conclusion MRI was superior to other imaging methods in diagnosis of acute suppurative osteomyelitis.

Guided by the innovation theory and ideology, the authors'hospital saw to it that the main line of innovative progress ran through the entire process of its development and set up a management engineering framework for innovation in six chief aspects. It managed to achieve “three firsts”, viz. the first to put forward in the domestic medical industry the suggestion of taking strategic actions so as to promote the construction of a clean and honest administration in the hospital; the first among hospitals of the armed forces to cultivate an “experimental plot” that partook of no money earmarked for national defense; and the first among large general hospitals at home to develop into a non profit hospital without government subsidies. It also attained remarkable results in the fight against SARS.

Objective To evaluate the valuations of the intracranial vertebrobasilar arteries using CT angiography (CTA) in order to improve the understanding of various variants in intracranial vertebrobasilar arteries.Methods The CTA images of 435 subjects were analyzed retrospectively.The data were collected by a 16-slice CT scanner.All the CTA images were processed technically by the maximum intensity projection and volume rendering.The intracranial vertebrobasilar arteries were measured and analyzed.Results Among the 435 subjects,bilateral intracranial vertebral arteries (V4) showed symmetry in 183 (42.07%) and dissymmetry in 252 (57.93%).Hypoplasia were found in 27 subjects (6.21%) on the left V4 segments and 36 (8.28%) on the right V4 segments,and a total of 21 (4.83%) were directly continued as the ipsilateral posterior inferior cerebellar arteries on the unilateral V4 segments.There were 2 subjects (0.46%) with vertebrobasilar dolichoectasia.There were 32 subjects (7.36%) had fenestration variation,3 of them (0.69%) were on the V4 segments,10 (2.30%) at the junctions,and 19 (4.37%) in the basilar arteries.Two subjects (0.46%) had persistent trigeminal arteries.Conclusions The variations of intracranial vertebrobasilar arteries mainly include angiodysplasia,vertebrobasilar dolichoectasia,fenestration variation,and persistent trigeminal artery.As a noninvasive vascular imaging method,CTA may accurately and visually assess the anatomic variation of intracranial vertebrobasilar artery,and provide imaging guidance for the preoperative evaluation of posterior fossa surgery.

Objective To investigate w hether the iterative reconstruction (iDose 4 ) technique improves imaging quality of the low-radiation-dose w hole brain CT perfusion (CTP). Methods Thirty-five consecutive patients w ith clinical y suspected ischemic stroke w ere col ected. Bril iance 256 iCT w as used to perform low-radiation-dose w hole brain CTP, and the filtered back projection (FBP) and iDose 4 algorithm w ere used to conduct image reconstruction. The noise and signal to noise ratio of the 2 kinds of reconstruction algorithms, as w el as the imaging quality of each parameter map w ere compared. Results The effective dose of the w hole brain CTP w as 2.2 mSv. Compared w ith FBP, the noise of each region of interest in the iDose4 Tmax map was decreased significantly ( P<0.05) and the signal to noise ratio was increased significantly (P<0.05). The imaging quality scores (median, interquartile range) reconstructed by FPB group w ere significantly low er than by iDose 4 for cerebral blood flow (CBF) map ( 5.00 [3.00-6.00]vs. 6.00 [5.00-6.00]; Z= -2.784, P=0.005), cerebral blood volume (CBV) map ( 6.00 [5.00-6.00] vs. 6.00 [6.00-7.00]; Z= -3.674, P<0.001), and mean transit time (MTT) map (4.00 [3.00-5.00] vs. 5.00 [4.00-6.00]; Z=3.394, P=0.001). The proportions of the poor quality in CBF map ( 34.3%vs. 11.4%;χ2 =7.036, P=0.030), CBV map (11.4%vs.2.9%; χ2 =7.485, P=0.024 ) and MTT map (28.6%vs.11.4%;χ2 =5.318, P=0.070) reconstructed by FBP w ere significantly higher than by iDose 4 . Conclusions The iDose4 technique may improve imaging quality of low er-radiation-dose CTP.

[Objective]To investigate the micro-structural alterations within whole brain white matter(WM) in cough syrup abuse addiction patients containing codeine,and to explore the correlation between aberrant WH and abuse time of cough medicine abuse patients.[Methods]Thirty cough syrup abuse addiction patients containing codeine and 30 controls participated in the study. Structural changes in FA and(mean diffusivity)MD were examined in cough syrup abuse addiction patients containing codeine which derived from DTI tractography. Pearson correlation analysis was performed to compare the mean FA value and duration of cough syrup abuse addiction in patients.[Results]Cough syrup abuse addiction patients containing codeine had lower FA value in bilateral anterior limb of internal capsule(ALIC)and higher MD in the bilateral hippocampus and insula,right anterior cingulate cortex(ACC)and superior temporal gyrus,compared to the controls. Cough syrup abuse addiction group also had positive correlation between mean FAvalues and duration of cough syrup abuse addiction in patients.[Conclusion]Micro-structural alterations within whole brain white matter(WM)are found in cough syrup abuse addiction patients containing codeine. This disturbance progresses as duration increases of cough syrup abuse addiction in patients.

Objective To establish an assay for the detection of Streptococcus pneumoniae by real-time fluorescence quantititive polymerase chain reaction (PCR).Methods Special primers and probe for the autolysin A (lytA)gene were designed.The sensitivity and specificity of primers and probe were studied,and cut-off of cycle threshold was assayed.158 clinical specimens were confirmed by real-time fluorescence quantitative PCR and bacterial culture method.Results Primer and probe design for LytA gene could sensitively detect serotype Streptococcus pneumoniae strains of common pathogenic,and the sensitivity was 100 copies.Among 35 strains of Streptococcus pneumoniae,34 cases were detected to be positive for Streptococcus pneumoniae by real-time fluorescence quantitative PCR,while 1 case was detected to be negative;among 15 strains of non-Streptococcus pneumoniae, all were detected to be negative.Among the 158 clinical sputum specimens,34 cases with Streptococcus pneumoniae were detected by real-time fluorescence quantitative PCR,while only 10 cases with Streptococcus pneumoniae were detected by the culture method.White blood cells count and time in hospital of cases with Streptococcus pneumoniae were higher than those of cases without Streptococcus pneumoniae (P <0.05 ). Conclusion Real-time fluorescence quantitative PCR is a sensitive and specific assay for the detection of Streptococcus pneumoniae.It can be used for the diagnosis of Streptococcus pneumoniae.
