Serum C-reactive protein(sCRP) is an acute-phase reactant that exhibiting negative correlation with serum albumin concentration. It was reported that sCRP is an independent predictor of survival in both hemodialysis and peritoneal dialysis patients, and an acute phase inflammation could be preceded by protein catabolism, hypoalbuminemia, anorexia and even atherosclerotic cardiovascular disease. We have evaluated serum biochemical parameters including albumin and prealbumin, Kt/Vurea, nPCR, SGA score, anthropometric parameters and diet history in 30 ESRD patients maintained on chronic hemodialysis subdivided by sCRP concentration. Upon comparing the two subgroups[high CRP group(sCRP >or= 0.4mg/dL), n=15 vs. normal CRP group (sCRP<0.4mg/dL), n=15], high CRP group showed significantly lower levels of hemoglobin(9.3+/- 0.7 vs. 9.8+/-0.6g/L, p<0.05), hematocrit(28.3+/-2.3 vs 29.8+/-1.696, p<0.05), creatinine(9.6+/-3.1 vs. 12.2+/-2.5mg/dL, p<0.05), prealbumin(20.9+/-5.0 vs. 25.8+/-6.4mg/dL, p< 0.05), SGA score(5.0+/-1.2 vs. 5.9+/-0.7, p<0.05), and percent of patients who have higher nPCR than protein intake(85.7 vs. 28.6%, p<0.05). Ferritin was significantly higher in high CRP group(503.1+/-205.7 vs. 323.3+/-186.6, p<0.05). There were no differences in age, sex, duration of hemodialysis, prevalence of diabetic nephropathy and cardiovascular disease, Kt/Vurea, nPCR, residual renal function, amount of protein intake and other nutritional parameters. In conclusion, there was higher probability of malnutrition, anemia and protein catabolism in hemo-dialysis patients with elevated sCRP concentration.

Resveratrol has been reported to exert anticancer activity via modulation of multiple pathways and genes. In this study, we examined the effect of resveratrol on YD-10B human oral squamous cell carcinoma cells and its molecular mechanisms of action. We found that resveratrol inhibited the proliferation of YD-10B cells in a dose- and timedependent manner. The suppressive effect of resveratrol was accompanied by a reduction in Bmi-1 gene expression.We observed that silencing the Bmi-1 gene by small interfering RNA effectively downregulated the levels of GLUT1 mRNA and protein, which were also repressed by resveratrol. Bmi-1 silencing increased the number of YD-10B cells in S-phase arrest by approximately 2.3-fold compared with the control. In conclusion, the results of the present study demonstrate, for the first time, that resveratrol suppresses Bmi-1-mediated GLUT1 expression in human oral squamous cell carcinoma cells and suggest that the specific molecular targeting of Bmi-1 and/or GLUT1 expression can be combined with a chemotherapeutic strategy to improve the response of oral cancer cells to resveratrol.

BACKGROUND: Coronary stenting is one of effective and well-accepted treatments for coronary artery disease. On the other hand, side branch occlusion (SBO) is a known complication of percutaneous transluminal coronary angioplasty (PTCA) and coronary stenting. Accordingly, this study was designed to determine the incidence, predictors and acute clinical outcomes of SBO. METHODS: Coronary angiographic findings of 45 patients who had total 98 side branches originating from the stented segments were analized before and just after coronary stenting. Bifurcation lesions were divided into 3 types : type 1, type 2, type 3 and each type was subdivided into type A with significant ostial narrowing (diameter stenosis >or=50%) and type B without significant ostial narrowing of side branches. Side branch occlusion was defined as development of total occlusion or morphologic changes from type B to type A or reduction of TIMI flow more than grade 1 compared with pre-stenting flow of side branches. RESULTS: After coronary stenting, SBO occurred in 20 of 98 side branches (20.4%). SBO was significantly related with history of previous myocardial infarction (p=0.02), threatened side branch morphology (p=0.016) and poor pre-stenting flow of side branches (p=0.014). There were no serious clinical events such as myocardial infaction and death associated with acute SBO. CONCLUSION: Acute SBO can be developed in a few stented patients. Signifiant clinical and angiographic predictors of SBO just after coronary stenting were the history of previous myocardial infarction, threatened side branch morphology and poor pre-stenting flow of side branches.

BACKGROUND: This research is to determine the chief complaints and related features of elderly patients who are presented to emergency department with medical problems. METHODS: Medical records of patients, 65 years or above, who visited Uijeongbu Hospital Emergency Center between January 1, 2012 and June 30, 2012 were reviewed retrospectively. Age, gender, mode of transportation to the hospital, chief complaints, and diagnosis were among the subjects analyzed. RESULTS: Elderly patients with medical problems, 3,468 visited the emergency department, constituting 12.66% from 27,396 patients in total during the research period. Patients aged 70 to 74 were 28.45%, composing the most among the age groups. Ambulance was the mode of transportation used by 43.06% of the patients and 42.96% of them stayed overnight, while 11.13% stayed in the intensive care units. The most frequent chief complaints were abdominal pain (16.81%), dyspnea (13.96%), and fever (11.16%). The most common diagnosis for patients with abdominal pain was gastritis (20.75%), chronic heart failure (26.03%) for dyspnea, and pneumonia (28.96%) for fever. The main diagnoses of in-patients according to the order of frequency were cerebral vascular accident (16.38%), pneumonia (12.48%), and chronic heart failure (6.04%). CONCLUSION: The number of elderly patients who stayed overnight and stayed in the intensive care units have increased comparing to younger patients. The top 10 most frequent chief complaints accounted for 78.92% by medical elderly patients. The results of this research could be used for the development of geriatric emergency medicine training programs and critical pathway for interns and residents.

Isolated noncompaction of the ventricular myocardium (INVM) is a rare cardiomyopathy resulting from a failure of normal endomyocardial embryogenesis and it has been categorized as a form of unclassified cardiomyopathy. The disorder is characterized by an excessively prominent trabecular meshwork with deep intertrabecular recesses. Although the disorder is sporadic, familial incidence may occur. Clinical symptoms and prognosis of INVM may differ markedly, and range from an asymptomatic course to a severe cardiac disability. The diagnostic method of choice for IVNM is echocardiography, which reveals multiple prominent trabeculations with deep intertrabecular spaces communicating with the left ventricular cavity in the middle and apical segments of the left ventricle. The authors report a case of INVM in a family in which three adult members (a brother and two sisters) were found to be affected by this disorder. They were all asymptomatic. The diagnosis of the disorder was made first in the 36-year-old brother by transthoracic echocardiography (TTE) and multidetector CT (MD CT), during the process of preoperative evaluation for surgical treatment of low back intervertebral herniated disc. TTE and MD CT showed similar and peculiar findings of INVM. Echocardiographic screening in all first-degree relatives of this patient, in order to identify asymptomatic patients, demonstrated INVM in two elder sisters.

An adult beagle dog was presented with a cervical mass detected by palpation and computed tomography. Fine needle aspirates revealed numerous epithelial cells with plasmacytoid appearance and frequent naked nuclei. Histologically, the mass consists of multiple packets of neoplastic cells and extensive areas of necrosis and fibrosis. Neoplastic cells were also found in submandibular lymph nodes. Immunohistochemistry showed that neoplastic cells were positive for calcitonin and negative for thyroglobulin. Based on these findings, the cervical mass was diagnosed as thyroid C-cell carcinoma. Almost one year after the surgical excision, the dog remains healthy without any symptom of recurrence or metastasis.

BACKGROUND AND OBJECTIVES: The coronary sinus (CS) is a small tubular structure just below the tricuspid valve. The dilatation of the coronary sinus as well as the inferior vena cava and the hepatic vein may provide echocardiographic signs of systemic congestion. The aim of this study was to evaluate the correlation of size of coronary sinus that had abnormal echocardiographic findings with or without congestive heart failure. SUBJECTS AND METHODS: Echocardiographic examinations of coronary sinus were performed on 58 patients (M : F=20 : 38) who had abnormal echocardiographic findings with current or previous symptoms or signs of congestive heart failure (group 1), and on 63 patients (M:F=27:36) who had abnormal echocardiographic findings but that had never had symptoms or signs of heart failure(group 2) and 94 healthy volunteers (control group, M:F=52:42). The CS was mesured using a two-dimensional echocardiogram in the right ventricular inflow view (5-10 mm below the Thebesian valve at end-systolic phase). RESULTS: In the normal control group, the median size of the CS was 6.2+/-1.2 mm, and showed no difference between gender and age. The sizes of the CS in groups 1 and 2 were 9.0+/-2.3 and 6.4+/-1.3 mm, respectively. There were differences between groups 1 and the normal control group (p<0.001), and between groups 1 and 2 (p<0.001), but a slight change between group 2 and the normal control group. In group 1, the size of the coronary sinus was related with the duration of heart failure (r=0.32, p=0.016), but no correlations to body surface area, left ventricle dimension and TR peak velocity were shown. In the presence of heart failure, as diagnosed according to the size of the CS, the predictive value was high when the size of the CS exceeded 8.0 mm, with an accuracy of 84%. In heart failure, the median size of the IVC was 16.6+/-5.4 mm, the variation rate of the IVC during the respiratory cycle was 0.40+/-0.13, and the variation rate of the CS during cardiac cycle was 0.31+/-0.20. The size of the CS was not related with the size of the IVC, but there was an inverse correlation between the size of the IVC and its variation rate (r=-0.434, p=0.037). The size of the IVC was inversely correlated with the variation rate of the CS (r=-0.490, p=0.024). There was a correlation between the variation rate of the CS and that of the IVC (r=0.411, p=0.021). Comparing the groups with and without systolic flow reversal into the CS in congestive heart failure patients with tricuspid regurgitation, in the former there wrer distensions of the CS, IVC and LA dimensions and reductions in the variation rates of the CS. CONCLUSION: The measurement of the size of the CS and the variation rate of CS may provide valuable information concerning the presence and duration of congestive heart failure.

The aim of this study was to propose new more reliable peripheral nerve transection model to overcome the defect of the traditional sciatic axotomy model by specifically transecting L5 spinal nerve just after emerging from the intervertebral foramen and confining analysis area to the L5 spinal segment. The adult male Sprague-Dawley rats, weighing 300~350 g at the time of surgery, were used for the experiments. Four different experimental groups were used. 1. Sciatic nerve transection (Sc-Tx) group: transect the sciatic nerve in the popliteal fossa where it divided into the common peroneal nerve and tibial nerve. 2. L5 spinal nerve transection (L5-Tx) group: L5 spinal nerve was specifically transected. 3. Suture (Su) group: L5 spinal nerve was transected and immediately sutured. 4. Control group: the same surgical procedure with L5 spinal nerve transection group was performed except for the excision of L5 spinal nerve. To distinguish L5 motoneurons from the other level ones, the animals were received the retrograde tracer, FluoroGold into the axotomized proximal nerve stump. Serial coronal frozen sections at 40 microm thick through the L4 to L6 spinal segment was performed and the resultant total number of sections was about 180. Approximate serial 50 sections (approximately 2 mm) could be considered as the L5 segment based on the number of the fluorescent signals (above 20). L5 spinal segment could be differentiated from L4 and L6 segment based on their morphological characteristics under Cresyl violet stain. In L5-Tx group, at 2 and 4 weeks post-transection, the number of L5 spinal motoneurons was reduced by 8%. Meanwhile, Sc-Tx and Su groups showed no statistically notable changes. In this study, the authors could propose more reliable peripheral nerve axotomy model than the conventional sciatic nerve axotomy model by specifically transecting L5 spinal nerve and confining the investigating area within the L5 spinal segment.
