Objective To analyze the risks for medical equipment and realize risk control.Methods The medical risk management plan was proposed based on the classification of medical equipment risks. Results Hierarchical management of medical equipment was realized based on the quantitative evaluation of risk grade. The desired target was implemented, and medical equipment risk was controlled properly.Conclusion The introduction of risk management into medical equipment management benefits medical staff, medical service and patient.

The alkaline elution and fluorometrie DNA assay were adapted to the evaluation of DNA single-strand breaks in the cultured human fetal lung 2BS cell. the DNA damage was induced in vitro by the treatment with Alternariol monomethyl ether (AME) and Alternariol (AOH) which were the main mycotoxins of Alternariol alternata. The results showed that both AME and AOH could induce the DNA single-strand breaks in the cultured human fetal lung 2BS cells and there existed the dose-response association betweenthe fractions of DNA remaining on the filters and the doses. The fractions of DNA remaining on the filters were 0.57?0.04, 0.45?0.02, 0.30?0.02, 0.18?0.01 respetively under the AME concentration of 10, 25, 50, 100?g/ml and were 0.68?0.3, 0.54?0.01, 0.47?0.03, 0.34?0.01 respetively under the AOH concentration of 0.1, 1, 5, 10?g/ml when DNA was eluted for 6hr. It were significantly different from the fractions by solvent control (0.87?0.02) (P

Objective:To promote the application of barcode technology and establish comprehensive barcode management platform for medical equipment in order to achieve precise management of medical equipment just like ID.Methods: Combined with information management of barcode was effectively applied to the medical equipment asset; analyzed the underlying application of barcode technology in the field of equipment asset management; finally, to clarify the application effect of barcode technology in precise equipment asset management.Results: The application of barcode technology has realized dynamic management for the whole life cycle of medical equipment, and effectively improved management method and efficiency of hospital medical equipment asset.Conclusion:Through informatization to support precise management for medical equipment, and this method can form more scientific and technological barcode technology management mode for medical equipment asset. This mode can reduce the workload and difficulty for routine equipment asset management, enhance the precise management level for equipment asset, and provide a powerful technical guarantee for the reasonable and effective integration of hospital equipment assets.

Objective To understand how resistance and whether its compensatory hyperinsulinemia will influence the ovulatory function and sex hormone level,especially in the testosterone level and blood lipid level and to observe the effects of metformin on the polycystic ovary syndrome with pseudoacanthosis nigricans and the insulin resistance.Methods The method of the research is to carry out a three-month tretment for 30 patients who were suffering from the polycystic ovary syndrome with the pseudoacanthosis nigricans and the insulin resistance.During the treatment much attention was drawn to the following aspects of the patients.Such as the body mass index,the waist hip ratio,the fasting blood glucose,the fasting insulin,two hours after postcibal blood glucose and postcibal insulin,the insulin sensitive index,the change of blood lipid and sex hormone level,and the skin lesion change.Results After the treatment,all the indexes fell except that the insulin sensitive index rose.There was significancely difference(P

AIM: To observe the effect of ?-glucosindase inhibitor, acarbose on the aortic collagen nonenzymatic glycosylation in streptozotocin-induced diabetic rats . METHODS: The treated group (DM+A) was given acarbose (1 mg?kg -1 ). The aortic collagen and its AGEs concentration were measured at the scheduled periods (1, 3 and 6 months ). RESULTS: During the observed period , the aortic collagen and its AGEs concentration were higher than that of control group in a time-dependent manner (P

Objective To study the two-phase flow dynamics distribution and red blood cell distribution under the fluid-solid coupling interaction in left coronary artery at the typical time point within one cardiac cycle,and to investigate the formation and development mechanisms of left coronary artery atherosclerotic plaque Methods The blood was regarded as a two-phase fluid.Based on fluid-solid interaction between blood and vascular wall,the computational fluid dynamics method was used to make the transient numerical simulation of two-phase flow in the left coronary artery under fluid-solid interaction;the distribution of blood flow in the left coronary artery at the typical time point within one cardiac cycle was studied,the relationship between hemodynamic parameters and the formation of atherosclerotic plaque was analyzed.Results A lowspeed eddy zone existed in an area between the distal segment of circumferential branch and the proximal outside of blunt-edge branch of the left coronary artery,where both internal wall shear stress and red blood cell volume fraction were very small and the blood flow pattern was very complicated.Conclusion At the lowspeed eddy zone that carries small wall shear stress,the lipid concentration polarization and macromolecular material deposition are easy to be produced.The area that has less red blood cells is liable to develop hypoxia,resulting in increased vascular wall permeability and intimal injury,which will activate the immune system,causing lipid accumulation in vascular wall and intimal hyperplasia and,thus,to induce the formation of atherosclerotic plaque.(J Intervent Radiol,2017,26:253-257)
