Objective To study the effects of two disinfection methods for simple respirators in order to select the better sterilization method for the disinfection of simple respirators.Methods One hundred and sixty simple respirators contaminated at the same degree were randomly divided into the manual group and the mechanical group equally .The former took the manual cleaning and disinfection and the latter the mechanical cleaning and disinfection for the disinfection and cleaning of simple respirators.The two groups were compared with regard to the qualified rate of disinfection at the outer and inner surface and the interface of the ball cavity after disinfection cleaning.Results The qualified rates of the mechanical cleaning and disinfection at various parts of the simple respirators were 100%.The qualified rate of manual cleaning and disinfection at the outer surface,the inner surface and the interface were 100%,91.25%and 93.75%,respectively.There was no significant difference in the disinfection effect at the outer surface and interface of simple respirators between the two groups(both P>0.05).But the two kinds of cleaning and disinfections at the inner surface of the respirators were significantly different as regards the qualified rate(P<0.05).Conclusion For the disinfection of simple respirator,the mechanical cleaning and disinfection is better than the manual cleaning and disinfection.

Objective To study radiological_anatomy of greater omentum and to address the related clinical implications,and to provide anatomic data for the radiological diagnosis and surgical application of greater omentum. Methods The anatomic distribution and morphology of the greater omentum as well as the anatomic relationship of the organs in the vicinity were analyzed by using axial,coronal,sagittal and 3D images from 16_detector row spiral CT scans of 60 individuals.We assessed the advantages of these images as well as the clinical significance.The data were recorded and analyzed by using SPSS11.5 software. Results 1.Advantages of three sections: axial section,the display of the fatty tissue and the anatomic distribution;coronal section,the vasculature; sagittal section,the anatomic relationship of neighbour organs.2.Three_dimensional reformatted images showed the return of the gastroepiploic vein.3.Gastrocolic trunk was revealed in 67.2% of cases.The free_hanging portion seemed to have the capability of 'migration': it located in the subphrenic spaces in 20.7% of cases and distributed in the right lower quadrant predominantly in 17.2% of cases.The CT value of fatty density within greater omentum was(-104.97?10.78)Hu and no statistical significance was found in the difference between greater omentum and the subcutaneous tissue.Conclusion Gastroepiploic vessel is the landmark for the location of greater omentum.Axial,coronal and sagittal sections together with 3D reconstruction images could produce a full display of greater omentum and provide valuable data for the radiological diagnosis as well as surgery of reconstruction, pancreas and portal hypertension.

Objective:To analyze the cause and treatment of ureteral stenosis in the early stage after kidney transplantation.Methods:250 cases of the kidney transplantation since 1993 to 2007 were collected and analyzed, including 141 men and 109 women,240 cadaveric transplantations and 10 living dononr transplantations. Results:In 8 cases(3.2%) ureteral stenosis occurred in the early stage following the renal transplantation;including hematoma compression(2cases);stenosis of ureter- bladder stoma(2cases);ureter torsion(1case);transplantal kidney torsion(1case);stomal leak(1case) and hydropsia of spermatic cord(1case). 7 cases required another surgical operation to remove the obstruction and the renal function recovered in these cases. Conclusion:The ureteral stenosis in the early stage of kidney transplantation was mostly contributed to the surgical reasons such as mis-perfamance. The occurance rate of ureteral stenosis should be reduced if each one step of the kidney transplantation is carefully performed. The open surgical managemen is a direct and effective method to remove the obstruction.

Objective:To compare the different ways of pulling out ureter double-J stent in females.Methods:172 female patients requiring urter double-J stent for different cases were chosen,including upper urinary calculus(150 cases),hydronephrosis with urterostenosis(14 cases),Ormond’s syndrome(3 cases) and postradiotherapy of uterine cervix cancer(5 cases).These cases were divided into three groups with different ways of pulling out the urter double-J stent.Results:The achievement ratio of cystoscope(100%) and rat-tooth forceps(98.1%) were higher than the blood vessel forceps(92.1%).Conclusion:The cystoscope operation requires the special equipment and cost more money and time.Compared to the blood vessel forceps,using the rat-tooth forceps to pull out the female ureter double-J stent is safe and more effective.

Objective:To introduce the experience on 8 cases living-related donor kidney transplantation(LD KT) in the past two years. Methods:8 patients underwent LDKT.The living donors(6 males and 2 females) received fully medical evaluation before operation. All cases were donated by blood relationship donors. CTA,ECT,HLA matching,PRA and CDC were done pre-operations. All t he donors underwent open nephrectomy,in which 5 cases donated right kidneys and 3 cases donated lef t kidneys. All the case underwent t he first renal transplantation. Triple-combined immuno suppressive protocols consisted of calcineurin inhibitors(CNI),MMF and steroid. Results:All donors were discharged in ten days postoperation. Af ter followed up for 2 months to 14 months,all the donors kept normal kidney function without impairment of life quality. All the recipients were discharged in 28 days with normal kidney function,and keep the normal renal f unction till to now. Conclusion: Accurate pre-operation assessment of the donor's safe and choose the donor kidney,good surgical technique are critical for the success. Optimal HLA matches and reasonable using of immunosuppressants can make the grafts survived long term. Living-rela ted donor kidney transplantation is a safe and effective reatment.

Objective:To explore the proper concentration of superparamagnetic iron oxide (SPIO) labeling bone marrow mesechymal stem cells and the biological influence of different labeling concentrations,and to evaluate the characteristics of magnetic resonance imaging by a 1.5 T MR scanner. Methods:BMSCs (5th)were incubated with different concentrations of SPIO particles. The location, distribution and the labeling ratio of SPIO particles in cells were observed. At an optimal concentration,samples of SPIO-labeled and unlabeled MSCs suspension in agar were imaged by MRI with T1WI,T2WI and T2*WI. and the signal intensity were measured and statistically analyzed.Results:Labeled SPIO particles were stained in cytoplasm. BMSCs were efficiently labeled (97% to 100%)in culture at 24 hours and particle concentrations(25 to 50?g Fe/ml medium). Compared with unlabeled cells,BMSCs loaded with SPIO had similar viabilitv and proliferation profiles at this proper range of labeling concentration. SPIO labeling caused a stronger low signal attenuation effect in T1WI、T2WI andT2*WI. Conclusion:BMSCs can be easily and efficiently labeled by SPIO without interference on the cell viability and proliferation,MRI visualization of SPIO-labeled MSCs is feasible,which provrdes basis for future in vivo studies.
