As foaming agent for the preparation of zeolite-foamed asphalt, the foaming water released from EC130 warm-mix additive and the residual zeolite minerals have different effects on the properties of asphalt. To investigate the effect of EC130 warm-mix additive on the high temperature performance and fatigue resistance of SBS modified asphalt, three additives of limestone powder, EC130 zeolite mineral and EC130 warm-mix additive were used, and the single-factor test was designed with additive dosage as variable. By temperature scan test, multiple stress creep recovery test and linear amplitude sweep test, the effects of EC130 zeolite mineral and foaming water released from EC130 warm-mix additive on the high temperature performance and fatigue resistance of SBS modified asphalt were compared and analyzed with reference to the effect of limestone powder on asphalt properties. The results show that like limestone mineral powder, the EC130 zeolite mineral in zeolite foamed asphalt can increase the elasticity and decrease the viscosity, which is favorable for rutting resistance but unfavorable for fatigue resistance. The foaming water in zeolite foamed asphalt can increase the viscosity and decrease the elasticity, which is favorable for fatigue resistance but unfavorable for rutting resistance.

Objective To observe the effect of curcumin on proliferation and invasion of the gastric cancer MGC-803 cells in vitro and in vivo, and to discuss the mechanism of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian rapamycin target protein (mTOR) signaling pathway. Methods The gastric cancer MGC-803 cells were divided into control group, low dose (10 μmol·L－1) of curcumin group, middle dose (20 μmol·L－1) of curcumin group，and high dose (40 μmol·L－1) of curcumin group. The proliferation abilities of the MGC-803 cells in various groups were detected by CCK-8 method；the invasion abilities of the MGC-803 cells in various groups were detected by Transwell method；the apoptotic rates of the MGC-803 cells were detected by flow cytometry. The MGC-803 cells were used to establish the gastric cancer transplanted tumor model and the mice were treated with low (0.5 mg·kg－1), middle (1.0 mg·kg－1)，and high (2.0 mg·kg－1) doses of curcumin, and the inhibitory effect of curcumin on the tumor growth of the mice in various groups was observed. TUNEL method was used to detect the apoptosis of the tumor cells in transplanted tumor tissue of the mice in various groups；the expression levels of PI3K-Akt-mTOR signaling pathway proteins in transplacted tumor tissue of the mice in various groups were detected by Western blotting ththod. Results Compared with control group, the proliferation abilities and number of invasion cells in different doses of curcumin groups were significantly decreased (P<0.05), and the apoptotic rates were significantly increased (P<0.05)； the cell proliferation ability and the number of invasion cells in low dose of curcumin group were significantly higher than those in high dose of curcumin group (P<0.05), and the apoptotic rate was significantly lower than that in high dose of curcumin group (P<0.05). Compared with control group, the volumes of transplanted tumor of the mice in different doses of curcumin groups were significantly decreased (P<0.05). The apoptotic rate of the cells in transplanted tumor tissue of the mice in control group was low, and the apoptotic rate of the cells in transplated tumor tissue of the mice in middle dose of curcumin group was significantly higher than that in low dose of curcumin group (P<0.05), while the apoptotic rate of the cells in transplated tumor tissue of the mice in high dose of curcumin group was significantly higher than that in middle dose of curcumin group (P<0.05). Compared with control group, the proteins expression levels of PI3K, phosphorylated Akt (p-Akt) and phosphorylated mTOR (p-mTOR) in transplanted tumor tissue of the mice in different doses of curcumin groups were significantly decreased (P<0.05)；the expression levels of PI3K, p-Akt, and p-mTOR proteins in transplanted tumor tissue of the mice in low dose of curcumin group were significantly lower than those in middle dose of curcumin group (P<0.05)； the expression levels of PI3K, p-Akt, and p-mTOR proteins in transplanted tumor tissue of the mice in high dose of curcumin group were significantly lower than those in middle dose of curcumin group (P<0.05). Conclusion Curcumin can effectively inhibit the proliferation of tumor, decrease the invasion ability, and increase the apoptotic rate of the tumor cells；its mechanism may be related to down-regulation of expressions of PI3K/Akt/mTOR signaling pathway proteins.
