Objective To evaluate the effects of ischemic postconditioning on nuclear factor kappa B (NF-κB) and intercellular adhesion molecule-1 (ICAM-1) expression during lung ischemia-reperfusion (I/R) injury in a dog model of cardiopulmonary bypass (CPB), and further investigate the pulmonary protection induced by ischemic postconditioning and the underlying mechanism.Methods Twelve adult mongrel dogs of both sexes, weighing 12-15 kg, were randomly divided into either CPB group or ischemic postconditioning group (IPO group) using a random number table, with 6 dogs in each group.CPB was established after the chest was opened in dogs anesthetized with pentobarbital sodium.Ischemic postconditioning was induced by 2 cycles of 5 min reperfusion followed by 5 min ischemia immediately after occlusion of the left pulmonary artery was released in group IPO.Before CPB (T1), before occlusion of the artery was released (T2) , and at 2 h after termination of CPB, lung specimens were obtained for examination of pathological changes which were scored (with light microscope) and for determination of the expression of NFκB and ICAM-1 (using Western blot) and wet/dry lung weight ratio (W/D ratio) in left lung tissues.Blood samples were collected from femoral arteries at T1 and T3 for blood gas analysis, and oxygenation index (OI), respiration index (RI) and dynamic lung compliance (Cdyn) were calculated.Results OI and Cdyn were significantly decreased, and RI was increased at T3 , and W/D ratio, pathological scores, and expression of NF-κB and ICAM-1 were increased at T2,3 than at T1 in the two groups.W/D ratio, pathological scores, and expression of NF-κB and ICAM-1 were significantly higher at T3 than at T2 in the two groups.Compared with group CPB, OI and Cdyn were significantly increased, and R1, W/D ratio, pathological scores, and expression of NF-κB and ICAM-1 were decreased at T3 in group IPO.Conclusion Ischemic postconditioning up-regulates the expression of ICAM-1 through inhibiting NF-κB activity, thus reducing lung I/R injury induced by CPB and improving the lung function in dogs.

Objective To investigate the in vitro effects of levofloxacin combined with fosfomycin upon 30 strains of clinical isolates of Staphylo-coccus aureus (15 strains methicillin resistant and 15 strains methicillin sensitive Staphylococcus aureus ) . Methods A checkerboard method that adhered to the recommendations of the National Committee for Clinical Laboratory Standards was applied to assess the synergism effect between levofloxacin and fosfomycin. The FIC index was calculated according to the results. Results The MIC_(50) was reduced significantly for the combination of levofloxacin plus fosfomycin against Staphylococcus aureus. The FIC indexes of methicillin sensitive Staphylococcus aureus (MSSA ) less than 0. 5, from 0. 5 to 1, from 1 to 2, more than 2 were 36. 4% ,63. 6% ,0,0 respectively. The FIC indexes of methicillin resistant Staphylococcus aureus ( MRSA) less than 0. 5 ,from 0. 5 to 1 ,from 1 to 2,more than 2 were 81. 8% , 18. 2% ,0,0, respectively. Conclusion In vitro the combination of subinhibitory concentration of levofloxacin and fosfomycin presented synergistic and additive effect There were no antagonism.

Background It has found that ischemic postconditioning (IPO) might decrease pulmonary ischemia/reperfusion (I/ R) injury,which is one of the main reasons of lung injury caused by cardiopulmonary bypass (CPB).It was found that aquaporins (AQPs) play a role in the maintenance of fluid homeostasis.But it is still unclear whether IPO influences the expression of aquaporin-1 (AQP1).This study was designed to investigate whether IPO can reduce CPB-related lung injury and affect the expression of AQP1 of lungs.Methods Twelve healthy dogs were divided into control group (C group) and ischemia postconditioning group (IPO group).CPB procedures were implemented.Ten minutes later,the left pulmonary artery was separated and blocked.Postconditioning consisted of two cycles of 5-minute pulmonary artery reperfusion/5-minute reocclusion starting at the beginning of reperfusion.The 2×4 cm tissues of both sides of pulmonary apex,superior,middle and inferior lobe were taken before CPB (T1),before occlusion and reopening of left pulmonary artery (T2,T3),and 2 hours after CPB (T4).Samples were used to evaluate lung injury degrees and to detect the expression of AQP1.At T1 and T4,blood was collected from femoral artery to calculate pulmonary function.Results At T4,each pulmonary function showed significant deterioration compared with T1.Lung injury could be found at the onset of CPB.However,the expression of AQP1 decreased and wet to dry weight ratio (W/D) increased after T2.In the left lung of C group,the worst pulmonary function and structures were detected.The slightest changes were discovered in the right lung of C group.A close relationship between W/D and lung injury score was found.The lung injury score was negatively related with the expression of AQP1.It was found that the expression of AQP1 was negatively connected with W/D.Conclusions In dog CPB models,lung injury induced by CPB was related with down regulated expression of AQP1.AQP1 is believed to be involved in the mechanisms of lung ischemia/reperfusion (I/R) injury caused by CPB.IPO increases the expression of AQP1,provides a protective effect on lung suffering from CPB,and alleviates CPB-related lung injury.

[Objective]To investigate the value of"pericardium crescent sign"in the diagnosis of non-calcified con-strictive pericarditis in CT.[Methods]Twenty-seven patients with non-calcified constrictive pericarditis and forty-six cardiac tumors confirmed by surgical pathology were analyzed retrospectively. All patients underwent non-enhanced and enhanced CT scan preoperatively.Pericardial morphology,density,enhancement features,appearance of atrium,ventri-cle and inferior vena cava of non-calcified constrictive pericarditis were analyzed. Pericardial morphology of cardiac tumors was also analyzed.[Results]Of the 27 patients with non-calcified constrictive pericarditis,18 patients developed"pericardium crescent sign",accounting for 66.7%,ventricular varying degrees of deformation in 13 cases,accounting for 48%;venous dilatation in 26 cases,accounting for 93%;atrial enlargement in 7 cases,accounting for 26%. In 46 patients with cardiac tumors,only 1 patient had a similar"pericardial crescent"sign.For the diagnosis of constrictive pericarditis using pericardial crescent sign,the sensitivity was 66.7%,the specificity was 97.8%,Youden index was 0.64. The area under the ROC curve was 0.82([0.71-0.94],P<0.001).[Conclusion]"Pericardium crescent sign"is important CT features of non-calcified constrictive pericarditis. It has high specificity for differentiating non-calcified constrictive pericarditis from pericardial tumor imaging.

We expirenced multiple hepatocellular adenomatosis, which was proved by pathology, in 38 years old man who had no prior history of predisposing factors. The radiologic findings were different by the size of tumor mass and intratumoral hemorrhage. Ultrasound demonstrated inhomogeneous hyperechoic large mass in segment 5 of right lobe and hyperechoic or isoechoic multiple small nodules in right lobe. Computed tomography demonstrated low density mass without contrast enhacement. Central high density is noted in hemorrhagic portion. Magnetic resonance T1-weighted image demonstrated high signal intensity in mass and hemorrhagic portion. T2-weighted image demonstrated slightly high signal intensity in mass portion, high signal intensity in hemorrhagic portionand double-layered peripheral rim. Gradient echo image well demonstrated inhomogenesity of mass.

PURPOSE: The purpose of the study was to compare symptoms, medical therapies, and nursing interventions with terminal cancer patients during the last four weeks of their lives in a hospice unit and general units. METHOD: For the descriptive survey study, data were collected by reviewing the medical records of 243 patients who died of terminal cancer at K hospital in Seoul. The data was analyzed by using Chi-square test and t-test. RESULT: The study findings are summarized as follows: There were higher frequencies in physical symptoms of constipation, itching sensation, pain, sleeping disturbance, soreness and dysuria for those patients in the hospice unit than those patient in general units. All emotional symptoms were recorded significantly higher for those patients in the hospice unit than those in general units. Regarding the major medical interventions, pain management was used more significantly for those patients in the hospice unit, but antibiotic therapy and resuscitation were used more significantly for those patients in general units. CONCLUSION: The hospice unit provided more comprehensive nursing interventions including psychological, spiritual, and family cares as well as physiological care for terminal cancer patients. The facts showed that those patients who would need hospice care in general units should be referred to the hospice unit at an appropriate time.
