Objective To investigate the expression and significance of survivin and CD44v6 in non-small cell lung cancer (NSCLC) and their correlation. Methods SP immunohistochemical technique was used to detect the expression of survivin and CD44V6 protein in 53 cases of NSCLC and 13 cases of para-eaneer nor-mal tissues. Results The positive rate of survivin and CD44v6 in NSCLC was 60. 38% and 69. 81% respec-tively,which was higher than that of normal pulmonary tissues adjacent to carcinoma(P <0. 01). The expres-sion of survivin and CD44v6 in NSCLC was related to lymph node metastasis (P < 0. 05), but not to patients' age and gender(P>0.05). The expression of survivin was related to TNM stages and cell differentiation (P <0. 05) ,but not to histology type(P >0. 05). The expression of CD44v6 in squamous carcinoma was significantly higher than that of adenocareinoma (P <0. 05),but the expression of CD44v6 was not related to TNM stages and cell differentiation (P >0. 05). There was no correlation between the expression of survivin and C1)44v6 (r = -0. 058, P >0. 05). Conclusion Survivin might be used to evaluate NSCLC development;CD44v6 might be used for the differential diagnosis of squamous carcinoma in NSCLC;both of them might be helpful to predict the metastasis of NSCLC. They might be two independent events in the process of NSCLC genesis and develop-ment.

BACKGROUND: The oxidation of low density lipoprotein (LDL) is a key influencing factor in the occurrence and development process of atherosclerosis. How is the merit of the method for the detection of the level of anti-serum oxidized LDL (ox-LDL) antibody on the evaluation of atherosclerotic plaque?OBJECTIVE: To study the method for the detection of serum anti-ox-LDL antibody in mice with apolipoprotein E (Apo-E) genetic defect to analyze the merits of serous level of anti-ox-LDL antibody on the evaluation of the area of atherosclerotic plaque in mice with Apo-E genetic defect.DESIGN: Single factor analysis of variance (a case-controlled study)SETTING: Laboratory of nutrition and metabolism diseases in a university.PARTICIPANTS: Mice with Apo-E genetic defect were grouped into positive group (series: C57B L/6J, n = 15), while normal mice were grouped into control group (series: C57BL/6J, n = 15).INTERVENTIONS: Mice of two groups were fed in separate cage on laminar flow shelf for free drinking and eating. The venous blood was drawn from the orbit of mice after 16 weeks for the separation of mice serum. The level of anti-ox-LDL antibody was detected by enzyme-linked immunosorbent assay (ELISA) in the separated serum from either mice with Apo-E genetic defect or normal mice. The area of atherosclerotic plaque was measured by image analysis after oil red O staining.MAIN OUTCOME MEASURES: ox-LDL level and atherosclerotic plaque area in mice with Apo-E genetic defect or normal mice.RESULTS: Anti-ox-LDL antibody level of mice with Apo-E genetic defect was[ (0. 079 ±0. 028)% ], which was significantly higher than [(0. 012± 0.001 )% ] of normal mice ( F= 10. 666, P < 0.01 ). The area of atherosclerotic plaque of mice with Apo-E genetic defect was (26. 25 ± 9.20) %, which was also significantly higher than 0% of normal mice, and moreover, there was a significant correlation between these two factors ( r =0. 638, P < 0.01).CONCLUSION: Serum level of anti-ox-LDL antibody in mice with Apo-E genetic defect is closely correlated with the area of atherosclerotic plaque,which is an important indicator for the generation of atherosclerosis in mice with Apo-E genetic defect.

Objective: To observe the effect of supplementation with anthocyanins (ANTH)purified from outlayer of black rice (BRF) on atherosclerotic (AS) plaque formation and inflammatory signal-transduction. Methods: Forth five male ApoE-defieient mice of 4 w age, were randomly divided into 3 groups: positive control (Group A), BRF (Group B ), ANTH (Group C), 15 in each group. Another 15 male ApoE-deficient mice served as negative control (Group D ). Group A and D were fed AIN-93G purified diet, Group C and B fed the same diet with 5% BRF not containing ANTH and 0.39% ANTH (containing 42% total flavonoids) respectively. The animals were fed for 20w, then blood, hearts and aortas were examined to verify inflammatory signal transduction. Results: There were no visible AS plaques in group D but much more severe in group A and B than C respectively. Compared with group A, supplememation of ANTH of BRF significantly increased the activity of T-NOS and cNOS, decreased the activity of iNOS but not significantly. The level of protein expression of ICAM- 1, NF-?B gene and mRNA expression of COX-2 gene were significantly decreased in aorta. Conclusion: The action of anthocyanins of BRF could be attributed to its anti-inflammatory activity to reduce COX-2, INOS and ICAM-1 expression which might be modulated by NF-?B.

Objective To assess the risk of secondary transmission induced by imported malaria in Jiangxi Province,so as to provide the evidence for adjustment of malaria surveillance strategies in the key groups and areas. Methods The Delphi method was used to establish the secondary transmission risk indicator system and the weight of each index was obtained. The data of malaria prevalence,vector distribution and intervention capacity were collected in 100 counties of Jiangxi Province from
2012 to 2015. The transmission potential index(TPI),intervention capacity index(ICI),and malaria risk index(MRI)were calculated for each county. The risk map was drawn with GIS software. Results The top ten counties with highly potential risk indicators were Linchuan District(2.131),Xinzhou District(1.609),Jiujiang County(1.404),Zhanggong District(1.365),
Fengcheng City(1.225),Qingshanhu District(1.184),Yudu County(1.171),Dingnan County(1.018),Xunyang District(1.015)and Zhushan District(1.006). The high risk areas were mainly distributed in the regions of the capitals of their prefectures and in counties with more floating population. Conclusions There are the risk of the secondary transmission induced by
imported malaria in Jiangxi Province. The high risk of the secondary transmission is shown in the areas with more floating population and weaker intervention capacity.
