Objective: : To investigate whether development of the sph e noid sinus affect the surgical approach via saddle area. Methods: The pneumatization of sphenoid sinus of 50 cadaver heads was studied through t hinner CT scanning of coronal, sagittal and axial position. The sphenoid sinus w as classified according to the degree of pneumatization of sphenoid sinus toward s sphenoid bone, small wing of sphenoid bone and epippium. Results: There were 4% conchal, 18% pre-sellar, 18% semi-sellar, 14% sellar, 46% sellar -occipital in 100 sphenoid sinus cases. The transversal diameter of left and ri ght was 18.48 mm and 17.58 mm; The sagittal diameter of left and right was 2 2.20 mm and 20.82 mm, The vertical diameter of left and right was 21.02 mm and 2 0.38 mm. The distance between centre track and the later wall of sphenoid sinus was 14.78 mm in left side and 15.18 mm in right side. Conclusion: Thinner CT scanning with coronal and sagittal position can clearly show pneum atization of sphenoid sinus on both sides. Different pneumatization of sphenoid sinus provide anatomical basis for choosing operation approach.

Objective To explore the relationship between left ventricular volume parameters and cardiac function in elderly patients with heart failure. Methods From January 1st, 2012 to December 31st, 2014,five hundred and twenty-eight heart failure elderly patients with coronary heart disease,hypertension,heart valve disease, dilated cardiomyopathy, and hypertrophic cardiomyopathy in Kailuan General Hospital were collected in this study. The left ventricle diastolic end volume ( LVEDV ) , left ventricle end systolic volume ( LVESV) and left ventricular ejection fraction of the patients were measured. The concentrations of N type brain natriuretic peptide ( NT-proBNP ) and related biochemical indexes were detected. Results Among the 528 patients with cardiac insufficiency,367 were males and 161 were females. Among them,there were 199 cases of heart function I,163 cases of heart function II,99 cases of heart function III and 67 cases of heart function IV. Correlation analysis showed that the correlation coefficients of LVEDV, LVESV and age were 0. 431 ( P=0. 001) ,0. 472 ( P=0. 001 ) and 0. 243 ( P<0. 001 ) , respectively. Logistic regression analysis showed that LVEDV ( OR=2. 654, 95%CI 2. 124-3. 894, P=0. 004 ) , LVESV ( OR=2. 939, 95%CI 2. 539-3. 256, P=0. 001),LVESV),NT-proBNP (OR=2. 921,95%CI 2. 888-3. 562,P=0. 002) were risk factors for heart failure. Conclusion The correlation between LVESV and cardiac function in elderly patients with heart failure is better than that in LVEDV,and the correlation between the two and cardiac function is better than that of age.

Objective This report aims to assess the exposure risk of aflatoxin B1 in edible vegetable oil in Guangxi.Methods By using margin of exposure (MOE),the report analyzes the dietary exposure of aflatoxin B1 in edible vegetable oil with the data from contamination survey and dietary intake survey.Results For the vegetable oil sample,the content of aflatoxin B1 was between 0.50-320.00 μg/kg.The detection rate of peanut oil was 78.08％ (114/146) which was higher than other vegetable oil,and the exceeding rate was 31.51％ (46/146).For peanut oil,the average content was 30.80 μg/kg,the dietary exposure of the population was 17.30 ng/kg BW,and the MOE was 18.For the prepackaged peanut oil samples,the average content of aflatoxin B1 was 6.33 μg/kg,which was below the limit.While for the bulk peanut oil,the average content of AFB1 was 41.50 μg/kg,which was more than 1.08 times of the limit,and the dietary exposure was 25.59 ng/kg BW.The MOE of bulk peanut oil was 12,1/8 of the prepackaged peanut oil.Conclusion Food safety regulators should pay more attention to bulk peanut oil products,the priority in the risk management measures.At the same time,related department should also promote healthy education for the residents.

Objective:To investigate the role of pleiotrophin (PTN) gene in carcino genesis using cDNA microarray and in situ hybridization. Methods:The expression of PTN gene in 5 cases of glioma, 10 laryngeal squamous cell carcinoma, 6 cases of hepatocarcinoma, and normal controls were detected by BioDoor 4096 type cDNA microarray and in situ hybridization. Results: The expression of PTN gene in carcinoma samples were significantly higher than in normal controls by cDNA microarray, the results was the same as by in situ hybridization. Conclusion: cDNA microarray is an effective technique in analysis of functional study of associated genes in carcinoma. High expression of PTN gene might be correlated with mechanism of multiple carcinoma. [
