ObjectiveAfter performed the silicone-rubber membrane implantation in rabbits, we investigated the efficacy and security of the silicone-rubber membrane implant through observed intraocular pressure, bleb and morphologic result. MethodsForty rabbits were divided into 4 groups by randomized fashiones. Each group consisted of 10 rabbits. Subscleroflapectomy and the silicone membrane implantation were operated in one eye of each rabbit. And the other eye was only performed subscleroflapectomy, which be controlled eye. The change of intraocular pressure, bleb were observed postoperatively. And every eye for histopathologic examination. ResultsThe lasted time of lower intraocular pressure and filtration bleb in implanted eyes were longer than controlled eyes in two groups. Light microscope revealed that patent drainage tract and bite site could be seen in cilicone membrafe implant eyes. The activity and regularity of fibroblast proliferation in implanted eyes and controlled eyes were similarly. The excessive expression of fibroblast proliferation was not excit ed by silicone membrane. ConclusionIt is characterized by safely, effectively and operate simply that silicone membrane implant drainage surgery act as a new drainage surgery.

Objective To investigate the application effect of quality control management in the prevention of indwelling catheter associated urinary tract infection in intensive care unit (ICU) patients. Methods Cases of patients stayed in the department of ICU undergoing indwelling catheter over 10 d were selected by using time stage sampling method. Totally 136 cases of patients were selected from January 1, 2012 to December 31, 2012, as the control group. A total of 145 cases of patients were selected from January 1, 2013 to December 31, 2013, as the performance group. Cases in performance group were taken standardized training and quantify the performance appraisal on the basis of measures in the control group. The urine routine was tested and bacterial was cultured at indwelling catheter 3 d, 7 d and 10 d, respectively. The indwelling catheter associated urinary tract infections of the two groups were compared. Results After the implementation of the performance appraisal management, the incidences of indwelling catheter associated urinary tract infection at 3 d, 7 d and 10 d were 4.8%(7/145), 19.3% (28/145) and 32.4% (47/145), respectively. Within each quarter, the incidence of indwelling catheter associated urinary tract infection was rising with indwelling catheter time prolonged. And the incidences of the first and second quarter were higher than three and four quarter. The incidences of indwelling catheter associated urinary tract infections at 3 d, 7 d and 10 d in the performance group were lower than the control group, the differences were statistically significant (χ2=4.494, 30.660 and 49.307, P < 0.05). Conclusions Standardized training of nursing staff in ICU and implementation of performance appraisal management could effectively improve the enthusiasm and sense of responsibility of the nurses, and effectively reduce the incidence of indwelling catheter associated urinary tract infection.

Objective To study the effect of cyclosporine A drug delivery system (CsA-DDS) on the prevention of posterior capsule opacification (PCO) after experimental intraocular lens implantation in rabbit eyes. Methods Twenty healthy New Zealand white rabbits, whose left eyes and right eyes were used respectively as experiment eyes and controls, were subjected to extracapsular lens extraction and artificial lens implantation. During the operation, CsA-DDS with poly (lactideco-glycolide) as carriers or empty DDS was implanted in the capsular bag for the experimental eyes and controls respectively. After the operation, anterior chamber reaction, intraocular pressure (IOP) and CsA concentration were monitored and twelve weeks after the operation, the eyes were extracted for histopathological and morphological examinations. Results There were no differences between the two groups in conjunctival congestion,IOP change and anterior chamber reaction. PCO was less severe in the experimental eyes than in the controls. Light microscopy revealed that posterior capsular membrane in the experimental eyes was slick, with no obvious proliferation,whereas in the controls, there were lens epithelial cell proliferation and cortex regeneration of different degrees.Morphological examination with electron microscope showed that in the experimental eyes, lens epithelial cells did not function actively and apoptosis occurred, whereas in the controls, epithelial cells presented active function. No marked ultrastructural changes were found in either group. Conclusion Cs-DDS can inhibit PCO after intraocular lens implantation in rabbit eyes and does not have toxic effects on the surrounding ocular tissues. Therefore, it has a good potential for clinical use in prevention of PCO.

Objective To discuss digital subtraction angiography(DSA)findings and interventional treatment of broncho-costoarterial pulmonary circulation fistula(BPF).Methods Fifty one patients with massive hemoptysis were undergone DSA showing 19 cases with BPF.All BPF were cmbolized with 500～700?PVA, silk particles and segments,and steel coil;separately or in combination according to shunt orifice size and blood flow velocity.Results There were 4 types of BPF demonstrated by DSA according to feeding and drainage vessels,including 13 cases of bronchial artery-pulmonary artery shunt(AAS),2 cases of bronchial artery-pulmonary venous shunt(AVS),3 cases of intercostal artery-pulmonary artery shunt(IAPS)and 1 case of bronchial arteriovenous malformatoin(B-AVM).All patients were followed up for 1～4 years,with 18 cases of complete symptomless during 7 days postoperatively obtaining,the effective rate of 94.7%.There were 3 recurrent cases within 1 year with the recurrent rate of 15.79%.Conlusions BPF is the main factor for inducing and aggrevating pulmonary hemoptysis and interventional embolization serves as a safe and effective treatment.The method could be used repeatedly for recurrent cases and furthermore emphasis should be put on treating the primary pulmonary diseases simultaneously.(J Intervent Radiol,2007,16:84-87)

Objective To explore the findings and clinical value of bedside ultrasonography in superior vena cava(SVC) syndrome in children after cardiac operations for congenital heart disease. Methods Bedside ultrasonography was performed on 6 children suspected of SVC syndrome after 5-38 hours[(22?11) hours] postoperatively,to view the structure and blood flow of SVC and its main branches. All the patients were reoperated as soon as diagnosed. Results Five children got severe SVC obstruction, marked with stenosis, turbulent, continuous and high velocity in SVC. Color Doppler flow imaging presented almost absence of flow due to nearly complete occlusion of the innominate vein in 1 child. Ultrasonographic diagnosis was confirmed by the reoperative findings. All the patients were cured by reoperation and discharged with normal ultrasonographic results. Conclusions Bedside ultrasonography can provide early and accurate diagnosis in children with SVC syndrome after cardiac operation.
