OBJECTIVE To investigate the distribution scope of the pan-drug resistant bacteria in the SICU patients including their producing environment and high risk factors in these two years and to approach its prevention and treatment policy. METHODS The distribution scope and the high risk factors of the pan-drug resistant bacteria in SICU were reviewed and analyzed from Jan 2005 to Jan 2007.RESULTS There were 11 cases in the period from Jan 2005 to Jan 2006; and was only 1 case from Jan 2006 to Jan 2007. CONCLUSIONS To establish the drug resistance monitoring system, attach great importance to isolation and education, to monitor the original region of the pan-drug resistant bacteria, and to adopt the comprehensive antibiotic policy to control the drug resistant bacteria. Among them, the early effective isolation of high risk patients may be very effective to reduce the producing and developing of the pan-drug resistant bacteria.

Objective To investigate multi-slice spiral CT (MSCT) and MRI features of stasis cirrhosis and the diagnostic value of MSCT and MRI. Methods MSCT and MRI findings of 35 patients with stasis cirrhosis were studied. The size of liver and spleen, the diameter of hepatic vein (HV), enhancement pattern of liver parenchyma, contrast medium reflux in inferior vena cava (IVC) and (or) HV, ascites, number of varices and correlated abnormalities were reviewed. Results The volume index of liver and spleen of 35 patients was 4 434.95 cm3 and 621.92 cm3 respectively. The mean diameter of HV of 27 patients (77.1%) was 3.61 cm and HV of other 8 patients (22.9%) were too small to show. Number of patients showed waves of borderline, inhomogeneous pattern of parenchymal contrast enhancement, contrast medium reflux in IVC and (or) HV, varices and ascites was 5 (14.3%), 29 (82.9%), 20 (57.1%), 16 (45.7%), and 6 (17.1%), respectively. Correlated abnormalities included cardiac enlargement 4 cases (11.4%), pericardium thickening 11 cases (31.4%), and pericardial effusion 2 cases (5.7%). Conclusions Stasis cirrhosis mainly demonstrate liver enlargement, inhomogeneous pattern of parenchymal contrast enhancement, contrast medium reflux in IVC and (or) HV, and slight portal hypertension. MSCT and MRI play invaluable roles in diagnosis, differential diagnosis and etiological diagnosis of stasis cirrhosis.

BackgroundThe morphological examination of macular disease is very important information for the early diagnosis.Spectral domain optical coherence tomography (SD-OCT) is a gold criteria in the diagnosis of macular diseases,but its clinical application is limited in the eyes with refractive medium opacity.The resolution ratio of conventional B-scan sonography is unsatisfactory.20 MHz B-scan sonography may be a new approach to maculopathy.ObjectiveThis study was to evaluate the clinical value of 20 MHz B-scan ultrasound by comparing morphological changes of different maculopathies observed by 20 MHz ultrasound and spectral-domain OCT.MethodsA prospective study was designed.51 eyes of 51 patients with macular diseases who were determined by Tianjin Medical University Eye Center were enrolled in this study.Spectral-domain OCT was used to image the macular area,and then the 20 MHz B-scan ultrasound was used to examine the same eye to assess the value of 20 MHz B-scan ultrasound diagnosis.The macular diseases were typed according to the OCT manifestation.The characteristics of 20 MHz ultrasound for the same maculopathy were analyzed.All the patients subscribe the informed consent before the study.ResultsIn 10 eyes with macular hole determined by spectral-domain OCT,shallow dome-shaped lesion with central hollow was exhibited on the ultrasound image.The macular edema,retinal neuroepithelium layer detachment and retinoschisis were found in 16 eyes,6 eyes and 4 eyes by spectral-domain OCT,but the 20 M Hz B-Scan ultrasound presented with the focal belt-shaped elevation with non-echo zone below.In contrast,in 15 eyes of retinal pigment epithelium detachment in OCT,spectral-domain OCT showed stronger and thicker belt-shaped echo.Conclusions20 MHz B-scan ultrasound has certain value in the diagnosis and differentiation for several common maculopathies.Although it is not accurate as OCT in recognizing diseases,it could play an important role in refractive media opacity eye.

Objective To compare gait patterns in patients with metal-on-metal resurfacing hip arthroplasty(RHA)and big-femoral-head total hip arthroplasty(BHA)at one year postoperatively.Methods From June 2006 to March 2009,two groups of 30 RHA and BHA patients participated in the study.Gait parameters,knee and hip joint range of motions(ROMs)in gait cycles were measured at one year postoperatively by Vicon gait analysis system,and the values were used to calculate affected/unaffected ratios of patients themselves.Results No significant difference were found in affected/unaffected ratios of cadence,single limb support time,foot off,peak value of vertical ground reaction force,the hospital for special surgery score and the university of California at Los Angeles activity assessment between the two groups.However,several ROM affected/unaffected ratios in RHA group(hip range of flexion/extension,abduction/adduction,and rotation were 1.0323,0.9747,and 1.0558,respectively.The knee range of flexion/extension for affected/unaffected ratios was 1.0027)were significantly higher than those in BHA group(the corresponding values were 0.8615,0.7824,0.8162,0.9472,respectively).The P values were 0.007,0.005,0.006,and 0.037,respectively.Conclusion(1)Gait parameters of patients who underwent RHA and BHA were close to normal values at one year postoperatively.(2)At the follow up time point,joint ROMs of RHA patients are larger than those of BHA patients during gait cycle.(3)RHA can retain enough bone stock for future revision option,moreover,it can achieve maximum recovery of joint function.
