Tianjin Medical Journal 2014;(7):638-640
Objective To investigate the effect of cisplatin on proliferation and invasion of colorectal cancer cell line SW480. Methods SW480 cells were used as the research object, and untreated SW480 cells were used as the control group. Different concentrations of cisplatin was given at different times to intervene. The MTT, Transwell chamber and phos-phate determination methods were used to detect proliferation, invasion and Na+-K+-ATPase activity expression level in SW480 cells. Results The physiological concentration of cisplatin (70 μmol/L) inhibited the proliferation of SW480 cells at 48 h. There was no significant difference in the inhibition rate at 48 h compared with 72 h and 96 h. Treatment with 70 μmol/L cisplatin for 48 h reduced the number of cells through Matrigel membrane matrix. The Na+-K+-ATPase activity was significantly increased in 35, 70 and 140 μmol/L cells after treatment with 17.5, 35, 70 and 140 μmol/L of cisplatin in SW480 cells for 48 h, and Na+-K+-ATPase reached the highest level at 70 μmol/L of cisplatin. Conclusion The decreased activity of Na+-K+-ATPase may lead to the attenuation in proliferation and invasion of colorectal cancer cells, which may be associated with cisplatin resistance in colorectal cancer cell SW480.

Acta Universitatis Medicinalis Anhui 2015;(1):116-118
The peripheral renous blood which were taken from healthy volunteers and platelet was isolated. Platelet samples were randomly divided into six groups. The effects of different concentration of taurine( Tau) on benzo py-rene( BAP) induced platelet aggregation in vitro activation function were investigated by detecting the maximum platelet aggregation rate, the positive expression rates of platelet membrane surface CD62P and PAC-1. The results showed that platelet maximum aggregation rate had significant differences between each concentration of BAP-Tau groups and solvent control group in adenosine diphosphate(ADP) and collagen induced (P<0. 01). The positive expression rates of platelet membrane surface CD62 P and PAC-1 in BAP-Tau high concentration group had signifi-cant differences compared with solvent control group ( P<0. 01 ) . Different concentration of Tau could antagonize platelet function damage induced by BAP with a concentration gradient change.
