BACKGROUND: In order to treat obese individuals, control of caloric intake after determination of patient's energy expenditure and recommendation of exercise program with possible use of specific medication is advised. There are many limitations in measuring all individuals energy expenditure by calorimetry, thus estimation is made using many variables such as weight, height, age, and gender. But, commonly used equations to predict resting energy expenditure(REE) are thought to result in overestimation of energy expenditure for use with obese individuals. This study investigated difference between measured and predicted resting energy expenditure in obese individuals. METHODS: Subjects were 133 adults who were admitted either to Internal Medicine Department and ENT Department of Yeung Nam University Hospital and their resting energy expenditure was measured by indirect calorimetry. According to age, sex, smoking habits and body mass index, Measured REE by indirect calorimetry between groups was compared. Predicted REE estimated by 6 equations to measured REE was compared in the two groups by body mass index 27kg/m2 under 65 years old individuals. RESULTS: There was no significant difference of measured REE between groups according to smoking habits(p>0.05). In the older group(> or =65 years old), REE was lower compared to the younger groups(<65 years old)(p<0.05). In the obese group(body mass index>27kg/m2) measured REE was higher than the normal weight group(BMI<27kg/m2)(p<0.05). Among 108 individuals under 65 years old, other equation except for Fleish equation and Robertson and Reid equation were inaccurate when applied to the obese group. CONCLUSIONS: These commonly used prediction equations tend to overestimate the REE in obese individuals, and the best estimates for the obese seem to be derived from the Fleish and Robertson and Reid equations.

Objective To investigate the underlying mechnisms of Kangai-1(KAI1)gene,a tumor metastasis suppressor gene,on metastasis and prolification of pancreatic cancer cells.Methods The plasmin containing Ad-KAI1 was established and transfected into pancreatic cancer cell line PCNA Ⅰ.The PCNA Ⅰ cells were then divided into different groups according to the times induced by vascular endothelial growth factor(VEGF)and epidermal growth factor(EGF).The morphology and migrational ability of PANC Ⅰ cells were compared before and after transfection by microscopy and transwell method,respectively.The expressions of intercellular adhesion molecule-1(ICAM-1)and matrix metalloproteinases-9(MMP-9)in PANC Ⅰ cells were examined by immunocytochemistry before and after transfection.Results The migrational ability of PCNA Ⅰ cells transfected with Ad-KAI1 was siginificantly decreased compared with untransfected PCNA Ⅰ cells(P＜0.05).Immunocytochemistry study revealed that the expressions of ICAM-1 and MMP-9 were both positive in untransfected PCNA Ⅰcells,but were both negative in transfected PCNA Ⅰ cells.Conclusion The inhibitory mechanism of KAI1 gene on metastasis of pancreatic cancer is associated with down-regulation of ICAM-1 and MMP-9expressions.

Objective To summarize the experiences of 5-year relative living kidney transplantation in the minorities. Methods The clinical data of HLA matching, rejection, survival and causes of death were retrospectively analyzed from 2004 to July 2009. There were 97 blood relative donations, including 1 case of father → son, 1 case of daughter → father, 1 case of mother → son, 24 cases of donation between brother and sister, 2 cases of non-blood relative donors (husband and wife),1 case of inter-ethnics, and the remaining were collateral relative donors. All the donations were voluntary, and all the recipients were minorities and all donors were their blood relatives. There were no mismatch of gene matching of 6 antigenic sites (0 MM) in 1 patient, 1 mismatch point (1 MM) in 2 patients, 2 mismatch points (2 MM) in 5 patients, 3 mismatch points (3 MM) in 10 patients, 4 mismatch points (4 MM) in 21 patients, 5 mismatch points (5 MM) in 39 patients and complete mismatch in 22 patients. Results All donors were discharged after 1 week and followed up for 3-6 months. Blood creatinine was normal and urine protein was negative. Up to July 2009, the conditions of the recipients were as follows: (1) Ninety-one receptors survived after transplantation. The longest survival time was up to 5 years. Among 9 deaths, 1 case died from myocardial infarction, 1 case from hemorrhagic shock and the others from respiratory failure (7 %) ; (2) Two renal grafts lost their functions and the patients restarted dialysis, in whom the preoperative panel reactive antibodies (PRA) of 1 patient was high and the patient had postoperative acute rejection, and the other patient stopped immunosuppressive agents on his own, leading to renal function loss; (3) After transplantation 10 patients had acute rejection, of which 2 cases received methylprednisolone plus OKT3, and the remaining 9 patients were treated with methylprednisolone. All rejections were reversed; (4) Urethral fistula occurred in one case and was improved after 45 days. Three patients had vesicoureteral anastomotic stenosis and were cured surgically. lyrnph leakage occurred in one case and was improved after 2 months. Fourteen patients had lung infection, including 7 mild lung infections which were improved after treatment, and 7 severe lung infections which died from respiratory failure.Other complications included secondary diabetes mellitus (4 cases), urinary tract infection (2 cases),acute renal failure (2 cases), deep venous thrombosis (3 cases), drug-induced liver damage (5 cases),polycythemia (5 cases), hepatitis C (3 cases), chronic allograft nephropathy (3 cases), and all were improved after treatment. Conclusion Comprehensive assessments of the donors and receptors before transplantation are guarantee to successful living kidney transplantation from relative donors; Living kidney transplantation from relative donors has the advantages of good matching, short ischemia period of donated kidney, less rejections and high survival rate of transplanted kidneys.

We compared the effects of genistein and daidzein on the expression of chemokines, cell adhesion molecules (CAMs), and endothelial nitric oxide synthase (eNOS) in tumor necrosis factor (TNF)-alpha-stimulated human umbilical vascular endothelial cells (HUVECs). TNF-alpha exposure significantly increased expression of monocyte chemoattractant protein (MCP)-1, vascular adhesion molecule (VCAM)-1, and intercellular adhesion molecule-1. Genistein significantly decreased MCP-1 and VCAM-1 production in a dose-dependent manner, whereas CAM expression was not significantly lowered by genistein treatment. However, daidzein slightly decreased MCP-1 production. The effects of genistein and daidzein on MCP-1 secretion coincided with mRNA expression. Pre-treatment with either genistein or daidzein elevated eNOS expression and nitric oxide production disturbed by TNF-alpha exposure. A low concentration of isoflavones significantly inhibited nuclear factor (NF)kappaB activation, whereas a high dose slightly ameliorated these inhibitive effects. These results suggest that genistein had a stronger effect on MCP-1 and eNOS expression than that of daidzein. Additionally, NFkappaB transactivation might be partially related to the down-regulation of these mRNAs in TNF-alpha-stimulated HUVECs.

PURPOSE: The aim of this study was to evaluate the effect of repeated firings on the color of zirconia restoration with different shading method. MATERIALS AND METHODS: Three different types of zirconia frameworks (adding metallic pigments to the initial zirconia powder before sintering (Group NM), dipping the milled frameworks in dissolved coloring agents (Group KI), or application of liner material to the sintered white frameworks (Group KW) were used to support A3 shade dentin porcelain. Repeated firings (3, 5, or 7) were performed, color differences among ceramic specimens were measured using a colorimeter. Repeated measurements analysis of variance (ANOVA) was used to analyze the data for significant difference. The Tukey Honestly Significant Different (HSD) test was used to perform multiple comparisons (alpha = .05). RESULTS: 1. L*a*b* values of the ceramic systems were affected by the number of firings (1, 3, 5 or 7 firings) (P < .001) and shading methods (P < .001). 2. As the number of firings increased, the L* (for all groups) and a* value (for KW and NM groups) decreased and the b* value(for all groups) increased. 3. The mean color differences caused by repeated firings were perceptible (DeltaE > 1) for group KW and KI fired after 3 times, except for group NM fired after 7 times. 4. In order of decreasing DeltaE value fired after 7 times, the values were group KI(DeltaE = 2.26) > group KW (DeltaE = 1.47) > group NM (DeltaE = 1.08) (P < .001). CONCLUSION: Repeated firings influenced the color of the zirconium-oxide all-ceramic specimens with different shading methods.

PURPOSE: This study validated the musculoskeletal model of the human lower extremity by comparative study between calculated muscle parameters through simulation using modified hill-type model and measured muscle parameters through isokinetic exercise. The relationship between muscle forces and moments participated in motion was quantified from the results of simulation. MATERIALS AND METHODS: For simulation of isokinetic motion, a three-dimensional anatomical knee model was constructed using gait analysis. The EMG-force model was used to determine muscle activation level exciting muscles. The modified Hill-type model was used to calculate individual muscle force and moment in dynamic analysis. This method was validated by comparing analytical data with experimental data. RESULTS: The results showed that there was a significant correlation between calculated torques from simulation and measured torque from isokinetic motion experiments (R=0.97). We also found that muscle forces and moments during knee flexion and extension have nonlinearly proportional or inversely proportional relationship, since lower extremity muscles were simultaneously involved in flexion/extension motion and inner/outer rotation. CONCLUSION: We concluded that the simulation by using musculoskeletal model may be a useful mean to predict and recover musculoskeletal-related diseases, and analyze complicated experiment such as clash condition.
