Expression of vascular endothelial growth factor,S100A4 and survivin in thyroid carcinoma and their clinical significance / 中国基层医药

Xu XP,Xiao N);Department ofGeneral Surgery,Pingxiang People's Hospital,Pingxiang,Jiangxi 337000,China(Rong J) Objective To study the expression of vascular endothelial growth factor(VEGF),S100A4 and survivin in thyroid carcinoma and their clinical significance.Methods The expression of VEGF,S100A4 and survivin in normal thyroid tissues from 28 people and thyroid cancer tissues obtained from 73 patients were detect by immuno-histochemistry method.Results The positive rates of VEGF,S100A4 and survivin in thyroid cancer were 84.93%, 86.30% and 79.45%,which in the normal thyroid tissues were 3.57%,7.14% and 14.29%,respectively.There were significant differences between every two groups,thyroid cancer and the normal thyroid tissues,statistically(χ2 =57.08,55.28,36.26,all P =0.000).VEGF,S100A4 and survivin in the positive expression of capsular infiltration carcinoma group were 97.37%,97.74%,97.74%,which in lymph node metastasis positive group cancer rates were 97.30%,94.60%,97.30% were significantly increased compared with no capsular infiltration group (71.43%, 77.14%,62.86%,respectively)and lymph node metastasis group(72.22%,77.78%,61.11%),the differences were statistically significant(χ2 =8.96,4.37,14.63,9.58,4.77,11.34,all P <0.05);the positive expression rate of three with thyroid cancer histological grade increased.Conclusion VEGF,S100A4 and survivin are closely related to the aggressive and metastatic character of thyroid cancer.A combination of VEGF,S100A4 and survivin may be of grate significance for predicting high aggressive and metastatic character in thyroid carcinoma.

Effect of Topiramate on Spatial Learning and Memory of KA-induced Rats / 中国心理卫生杂志

Objective:To investigate the chronic effect of topiramate on spatial learning and memory to young rats. Methods:P28 KA-induced rats were used. After 8-week treatment of topiramate, spontaneous recurrent seizures were recorded; Spatial learning and memory ability was evaluated by Morris water maze. Results: TPM-treated rats had significantly fewer(3.50?3.84) spontaneous recurrent seizures than rats without TPM treatment(7.36?3.75). On the first day of Morris water maze, they also had statistically longer latency to the platform(590.6?230.9 s) than those from the group without TPM treatment (422.6?122.3 s), but no latency differences were found in the following three days. TPM had no effect on water maze performance to rats without KA induction. After three days of interval, no differences were found in all groups under the same experimental situation.Conclusion:For developing rat brain, TPM has no impairment on the ability of long-term memory and information retrieval meanwhile its negative effect on spatial learning is temporary.
