Objective:To investigate the correlation between root and root canal diameter of maxillary central incisors and age by cone-beam computed tomography(CBCT).Methods:CBCT images of 420 cases of Chinese Han population were divided into 7 age groups as follows:1 5 -24,25 -34,35 -44,45 -54,55 -64,65 -74 and 75 -84(n =60).Root diameter and root canal diameter of maxillary central incisors at the 3 /4 level from the cemenal-enamel junction(CEJ)to root apical were measured.Linear-regression a-nalysis was used to analyze the correlation between root and root canal diameter of the teeth and age,T-test was used to examine the gender difference.Results:Mean root diameter(mm)of the teeth in males and females were 5.81 ±0.445 and 5.53 ±0.489(P <0.05),mean root canal diameter(mm)1 .20 ±0.396 and 0.96 ±0.236(P <0.05),mean of the ratio of root canal diameter and root diameter of the teeth 0.21 ±0.072 and 0.1 7 ±0.043(P <0.05)respectively.There were negative correlations between the ratio of root canal diameter and root diameter of the teeth with age (R2 =0.576,P <0.05).Conclusion:The ratio of root canal diameter and root diameter of maxillary central incisors is negitively correlated with age in Chinese Han population.The decrease of root canal diame-ter in males is more significant than that in females.

Aim To investigate the expression of vascular endothelial growth factor(VEGF) and its receptors in human hepatocellular carcinoma cell lines SMMC7721, HHCC and HepG2. Methods Immunohistochemical staining and reverse-transcriptase polymerase chain reaction(RT-PCR) were used to detect the mRNA and expression of VEGF and its receptors: VEGF-R1(Flt-1) and VEGF-R2 (KDR) in three human hepatocellular carcinoma cell lines, SMMC7721, HHCC and HepG2, as compared with ECV304 cells(human umbilical vein endothelial cells) and L929 cells(mouse fibroblast). Results All three human hepatocellular carcinoma cell lines expressed VEGF protein. Flt-1 mRNA and protein could be detected in SMMC7721 cells while KDR in HHCC and HepG2 cells. Conclusion The expressions of Flt-1 and KDR suggests that VEGF may be an autocrine growth factor for human hepatocellular carcinoma, at least for cell lines in vitro.

Objective To explore the effect of let-7c-1 on the learning and memory of PTZ-induced epileptic rats and its relevant mechanism.Methods A model of temporal lobe epilepsy (TLE) was induced via PTZ kindling in SD male rats.The epileptic rats were divided into epilepsy group,agomir-control group,let-7c-1 agomir group (12 rats for each).Twelve rats were served as a negative control group.The behavior and the expression levesl of let-7c-1,Bcl-2 protein and Caspase3 were evaluated at 28 days following PTZ.Results Compared to the negative group,the escape latency of epilepsy group was prolonged and the crossing times as well as the quadrant total distance in the target were reduced (P＜0.05).However,those parameters were not significantly different between the epilepsy group and the agmoir-control group (P＞0.05).Compared to the agmoir-control group,the escape latency of let-7c-1 agomir group was prolonged and the crossing times as well as the quadrant total distance in the target were reduced (P＜ 0.05).The expression levels of let-7c-1 and let-7c-1 were 1.35±0.32 in agmoir-control group and 62.53±21.01 in agomir group (F=50.97,P＜0.05).The expression levels of let-7c-1 were higher in let-7c-1 agomir group than in other groups (P＜0.05).Compared to the negative group,the expressions of Bcl-2 protein in other groups were decreased (P＜0.05) and the Caspase3 protein were increased (P＜0.05).Compared to the agomir-control group,the expression of Bcl-2 protein was significantly decreased and the expression of Caspase3 protein was significantly increased in let-7c-1 agomir group (P＜0.05).Conclusions The present study shows that let-7c-1 may impair the learning and memory of PTZ-induced epileptic rats through decreasing the Bcl-2 protein and increasing Caspase3 protein in the hippocampus.
