In medical equipment purchasing process, massive non-price factors' influences conduce to quite quantities of risks in the medical equipment purchase. To control the risks,this paper proposes the project management, the supplier management, the equipment traceability management and related suggestions. Management on purchaser is also discussed, which mainly includes professional stress analysis and the countermeasures research.

AIM: To observe the effect of tranilast on experimental COPD rats in terms of airway remodeling. METHODS: Forty eight SD rats were divided into two groups in random: untreated model group, tranilast-treated group. Another eight rats were selected as control group. The COPD rat model was established by passive smoking and intratracheal instillation of lipopolysaccharide (LPS) and then treated with sterile saline or tranilast (400 mg?kg~ -1 ?d~ -1 ) respectively. Eight rats in each group were killed in 7th, 14th, 28th day after the beginning of proceeding. Bronchoalveolar lavage fluid (BALF) was collected, and the total and differential cells were counted. The distribution and the ratio of type I to type III collagen in the lung tissue were determined using a sirius red polarizing microscopy morphometry method. Lung tissues were observed by hemotoxylin and eosin stain, then the image analysis were made. RESULTS: The total cells and the AM ratio in BALF of tranilast-treated group significantly decreased in comparison with those in model group (P

From the aspects of advantages, barriers, opportunities and challenges, this paper analyzed the environmental factors of Shanghai medical resources serving people in the Pan-Yangtze River Delta. As envisaged by the author, such services will provide medical resources information to patients from outside Shanghai, probe into feasible ways to medical insurance based on experiences drawn from serving such patients, help with the resources integration of medical systems in Shanghai, and probe into the potentials of telemedicine and distant medical e-learning, as well as improve hospital management levels and service functionality.

Bile acid can not only emulsify fat and facilitate the absorption of fat soluble substances,but also it is an important signaling molecules that plays an important physiological role by activating specific bile acid receptors.Takeda G proteincoupled receptor 5 (TGRS) is a membrane receptor of the bile acid,it can activate G-protein effectors and promote the expression of the second messenger and activate a variety of signal transduction pathways to exert physiological functions.The obstructive jaundice bile acid can cause a series of pathophysiological reactions through activating TGR5,which plays a significant role in the obstructive jaundice.In this article,the latest researches about the function and molecular mechanism of TGR5 in obstructive jaundice were reviewed in order to provide a new idea for exploring the new method and strategy to cure the disease.

[Objective]To verify whether or not the modified open-door laminoplasy preserving semispinalis cervicis insert into axis is effective in preventing postoperative axial symptom and maintaining postoperative cervical sagittal alignment.[Method]Since March 2002 to December 2003,forty-eight patients underwent modified open-door laminoplasy preserving semispinalis cervicis insert into Axis,among them,thirty-two patients who were followed up for more than 2 years were included in this study.Preoperative and postoperative JOA score,degree of axial symptom,ranges of neck motion,cervical curvature index were recorded and compared.[Result]Preoperative and postoperative JOA score was(9.04?2.9)and(12.5?3.1)respectively,with recovery rate as(44.9?26.9).There was significant difference between preoperative evident axil symptom rate(46.8%)and postoperative evident axil symptom rate(18.7%),while no significant difference between preoperative and postoperative ranges of neck motion,cervical curvature index was seen.[Conclusion]Modified open-door laminoplasy is less invasive to the posterior extensor mechanism especially the semispinalis cervicis than conventional open-door laminoplasy.This new procedure is effective in preventing postoperative morbidities often seen after conventional laminoplasy with adequate decompression of the spinal cord.

Objective To verify whether the modified open-door laminoplasty with C3 laminectomy is effectve in preventing postoperative axial symptom. Methods Since March 2001 to March 2005, 44 patients who underwent modified open-door laminoplasty with semispinalis cervicis insertion intact were included in this study(group A). 50 patients who underwent conventional open-door laminoplasty in the authors' department during the same period were served as control(group B). Preoperative and postoperative Japanese Orthopedic Association(JOA) scores, the degree of axial symptom, ranges of neck motion, cervical curvature index were recorded and compared. Results The average JOA recovery rate was 59.2%?11.3% for group A and 60.1%?19.5% for group B. There was no significant difference in JOA recovery rate between two groups. The rate of patients with evident axial symptoms was 22.7% in group A and 54.0% in group B, and the difference was statistically significant(P

[Objective]To verify the clinical outcome of cervical arthroplasty in the treatment of spondylotlc myelopathy exclusively.[Method]From January 2004 to August 2003,twelve spondylotic myelopathy patients who underwent cervical arthroplasty were included in this study.Preoperative and final follow-up Nuriek grade,Oswestry neck disability index(ONDI)score,neck and arm pain VAS score of patients were recorded and compared.Surgical outcome was also measured using odom' s criteria.[Result]100% of patients had good or excellent outcomes using Odom' s criteria,while the final follow-up Nurick grade,ONDI score,neck and arm pain VAS score were improved significantly compared with the preoperative valule.[Conclusion]Cervical arthroplasty is effective in the treatment of spinal cord compression secondary to spondylotic disease with interveterbral movement being preserved.
