How to fully utilize the large number of advanced medical equipment resources, how to monitor and manage equipment are focuses that hospital administrators pay much attention to. Methods: The effective performance appraisal of large-scale medical equipment can promote the resource allocation optimization, accurate and scientific management, reasonable and benign application, and then allows large-scale medical equipment fully and effectively applied to clinical practice. Results: Collecting basic data is the basis for performance appraisal of large-scale medical equipment; its instant validity, accuracy, and scientific can enhance the operability and the scientific accuracy of the performance appraisal for large-scale medical equipment. Conclusion:The acquisition of basic data has few specialized research in previous studies, the rules set up for basic data acquisition of large-scale medical equipment in this paper can improve the timeless, accuracy and normalization of the basic data using in the performance appraisal of large-scale medical equipment.

BACKGROUND:Lumbar fusion is a conventional effective measure to treat spondylolisthesis, spinal stenosis or with deformity. Bilateral pedicle screw fixation is recognized as the standard treatment for various spinal disorders, and has biomechanical and clinical advantages. OBJECTIVE:To evaluate the effects of bilateral pedicle screw fixation in the repair of lumbar disc herniation to restore disc height from the angle of imaging. METHODS: Clinical data of 42 patients with lumbar disc herniation were retrospectively analyzed. They al received bilateral pedicle screw fixation. Pain was evaluated before implantation, immediately and 1 month after implantation using Japanese Orthopaedic Association score of lower back pain and visual analog scale score. X-ray including anteriorposterior and lateral films of lumbar spine and MRI were used. CT was utilized to verify screw placement conditions and complications. RESULTS AND CONCLUSION:A total of 42 patients were folowed up for 3-6 months. Compared with pre-implantation, Japanese Orthopaedic Association score and visual analog scale score were significantly improved immediately after implantation (P < 0.01). There was no significant difference in Japanese Orthopaedic Association score between 1 month and immediately after implantation (P > 0.05). The height of intervertebral discs was significantly higher immediately and 1 month after implantation than pre-implantation (P < 0.01). The symptoms were lessened after fixation in al cases, and their qualities of life elevated. At 1 month, X-ray films and CT images revealed that no screw loosening, breakage or displacement occurred. The height of intervertebral discs was perfectly restored. No adverse events appeared in patients. These data indicate that bilateral pedicle screw fixation for lumbar intervertebral disc herniation can effectively restore the height of intervertebral discs, improve clinical symptoms and have biological and clinical superiority.

OBJECTIVETo investigate the effects of E 4031, a sodium calcium exchanger (NCX) agonist, on the isolated cardiac function and resting Ca2+ level in myocardial cells from rats with chronic heart failure.

METHODSRats chronic heart failure model was established by abdominal aorta coarctation with; Isolated heart perfusion by Langendorff apparatus was used to detect heart function and the effects of E 4031 on haemodynamic indexes; Myocardial cells of rats in the model group were extracted quickly and co-incubated with calcium fluorescent indicator fluo3/AM and the impact of E 4031 on the fluorescence intensity in myocardial cells were evaluated by confocal microscopy.

RESULTSHeart function of rats in the model group detected by Langendorff perfusion was significantly reduced after 12 weeks, E 4031 at 10 micromol/L could improve their left ventricular developed pressure(LVDP) and systolic / diastolic maximum rate (+/- dp/dtmax). Compared with the control and sham operation groups, the resting Ca2+ fluorescence intensity of the myocardial cells of rats in model group was at a higher level and went through a process of transient rise and drop, then stably remaining at a low level after co-incubated with 10 micromol/L E 4031.

CONCLUSIONE 4031 can improve the isolated heart function of rats with chronic heart failure, which may be associated with its enhancing the activity of NCX in the myocardial cell membrane and stabilizing intracellular Ca2+ level.

Liver is the main target organ of the metastasis of colorectal cancer.More and more researches demonstrate that including micro-environment of cancer,signal transduction pathway,abnormality of chromosomes and the gene which control cell proliferation and apoptosis are the most important mechanisms in liver metastasis of colorectal cancer.The metastasis of colorectal cancer is the result of all these factors.To study the mechanism can shed some light on prevention and therapy in liver metastasis of colorectal cancer.

Objective:To study the current status and needs of Community Care for disabled elderly in Beijing and put forward the suggestions for improving the elderly Community Care system. Methods:Descriptive statistical a-nalysis, Chi-square test and Multivariate logistic analysis were adopted to analyze the situation of Community Care for Disabled elderly using data from the community survey of elderly population in Beijing. Results:The status of health is not optimistic for Disabled elderly, there are high demands for the community health services and welfare facilities for elderly and the needs for services provided by part-time home care, day care and volunteers are high, but those services and facilities provided by communities were found to be inadequate. Conclusion:China has a large popula-tion base of Disabled elderly and its number grows fast, but community care supply is in shortage and cannot meet the needs of those people. It is therefore urgent to improve community health services and community care system.

Objective To investigate the role of intracellular protein tyrosine kinase (PTK) activation in vascular smooth muscle cells (VSMCs) migration mediated by angiotensin Ⅱ (AngⅡ). Methods Intracellular PTK activities were investigated by means of ?- 32 P incorperation in cultured rat VSMCs stimulated by AngⅡ. The migrated VSMCs were enumerated in a modified Boyden Chamber. Results Without any specific stimulus, only a few migrated cells were detected. However, the number of migrated cells were increased, under the condition of AngⅡ at the concentration of 1?10 -10 , 1?10 -9 , 1?10 -8 , 1?10 -7 and 1?10 -6 mol/L, by 3.7, 4.6, 5.9, 6.6 and 6.3 times respectively, compared with the control group. Intracellular PTK activities were also increased by 1.0,1.7,2.4,3.2 and 2.4 times compared with the control group, under the condition of AngⅡ at the concentration of 1?10 -10 , 1?10 -9 , 1?10 -8 , 1?10 -7 and 1?10 -6 mol/L, respectively. Statistical analysis showed that there was a significant positive correlation between AngⅡ-induced VSMCs migration and intracellular PTK activation. Correspondingly, PTK inhibitor Genistein significantly reduced AngⅡ-induced VSMCs movement ( P

Objective To explore the water quality of the product water from the centralized water supply system in Hunan, 2006. Methods The sanitary quality of the product water samples collected from 28 centralized water supply system in cities and 39 centralized water supply system in counties in Hunan, 2006, which distributed among the area of Xiangjiang River, Zishui River, Yuanjiang River and Lishui River, were determined and evaluated according to the Standards for Drinking Water Quality (GB5749—2006). Results The eligible rate of the water sample was 70.1%. Among 74 water quality indexes, 12 indexes (such as antimony,aluminum,pH value,manganese and so on) exceeded the standard limits in degrees in some centralized water supply systems. Most of the routine indices of water quality were unqualified and the reference indices were qualified. The quality of some water samples presented statistical difference in some indices (such as aluminum, sulphate, arsenic, et al) among 4 different river areas in Hunan province (P
