China Medical Equipment 2016;13(8):108-111
Objective:To evaluate the efficiency of high-tech medical equipment of county-level hospitals in Guangxi Zhuang Autonomous Region, and to provide a scientific foundation for high-tech medical equipment configuration planning for county-level hospitals.Methods: DEA model was used to evaluate the relative efficiency of 40 county-level hospitals in Guangxi.Results: 4 among 40 hospitals (10.00%) could be categorized as effective hospitals, and pure technical efficiency is not high in 30 hospitals (75.00%). The returns to scale decreased in 20 hospitals (50.00%), and 16 hospitals (40.00%) increased. The average number of the overall efficiency, pure technical efficiency and scale efficiency of the 40 hospitals were 0.684, 0.753 and 0.908 respectively. Conclusion: Departments concerned should set reasonable evaluation index to ensure that the evaluation is scientific. Hospitals should strengthen the internal management of high-tech medical equipment to improve the utilization rate of the equipment. Departments concerned are supposed to curb or enlarge the number of the high-tech medical equipment to improve the scale efficiency of the equipment.
3.Analysis of stability and healing on minimally invasive osteotomy for the treatment of hallux valgus.
China Journal of Orthopaedics and Traumatology 2016;29(3):228-231
To treat hallux valgus, minimally invasive osteotomy on 1st metatarsal neck,immobilization with "8-shape" bandagev was performed, and the effect was definited. The principles of osteotomy stability were analyzed from the osteotomy position, methods, direction and angle. The grinding drill was used to increase friction coefficient between the ends of osteotomy. Correct direction of osteotomy and suitable angle were the key point of stability. The immobilization with "8-shape" bandage complied with the principle of elastic fixation created the conditions for the slight movement of the osteotomy ends. Compared with internal fixation ,it was better on osteotomy healing,and the osteotomy ends were stable and healed with cartilage

In recent 30 years, stem cell transplantation for severe aregenerative anemia has obtained significant clinical progress, so a regenerative anemia has the possibility of healing. With the improvement of pretreatment, the incidence and severity of complications after stem cell transplantation have been controlled. In this article, we retrieved relevant articles in Pubmed Database, and found the research progress of stem cell transplantation for treating aregenerative anemia. This article investigated the effect of pretreatment improvement on controlling failure rate of stem cell transplantation.

Objective Preparing platelet rich gel through two-times centrifugal technique and co-culturing chondrocytes with PRG, then observing the proliferation and gene expression of chondrocytes, in order to provide a favorable way to prepare tissue engineering cartilage. Methods Centrifugating venous blood of rabbit through two-times centrifugal technique to obtain platelet rich plasma( PRP) ,then detecting the concentration of various growth factor in PRP. Admixing PRP with chondrocytes of rabbit and activating them with activator. After co-culti-vation,the proliferation of chondrocytes through MTT method and expression of ACAN,CollagenⅡand SOX-9 through realtime-PCR were ob-served,and compared with common cultured chondrocytes. Results The concentrations of PDGF-AB,TGF-β1,IGF-1 and VEGF in PRG were significantly higher than those in blood(P<0. 05). After co-cultivation, the proliferation rate of chondrocytes and the expression of ACAN,Collagen Ⅱ and SOX-9 were significantly higher than that of common cultured chondrocytes(P<0. 05). Conclusion Co-culturing chondrocytes with PRG is able to promote the proliferation and gene expression of chondrocytes. We considered that it is a excellent method to construct tissue engineering cartilage.

Secondary glaucoma is a kind of complications after vitrectomy, its etiologies are various and complex. Ineffective therapies might cause irreversible damage on optic nerves and visual field defect, even the loss in visual function. Nowadays, this project has been paid great attention by various researches both in China and abroad. Both the pathogens and therapies of secondary glaucoma after vitrectomy are analyzed as follows.

In recent years, laser microdissection followed by mass spectrometry (LMD/MS) has been successfully applied to the proteomic studies of formalin-fixed paraffin-embedded (FFPE) renal tissues. This new technique improves the diagnosis of kidney diseases and has a better potential for future clinical application. The review focuses on the use of this methodology for exploring the mechanisms, diagnosis and classification of kidney diseases including renal amyloidosis and membrane proliferative glomerulonephritis.
