Abstract:
Objective To explore the effect of triptolide(TL) combined with hyperthermia on proliferation and apoptosis of Hep-2 cells and its affect on cell cycle phases,and provide theoretical foundation for treatment of laryngocarcinoma.Methods Hep-2 cells at logarithmic growth phase were randomly divided into control,hyperthermia,TL,TL combined with hyperthermia groups.MTT method was adopted to investigate the proliferation inhibition rate of the Hep-2 cells.Cell cycle and apoptotic rate of Hep-2 cells were analyzed by flow cytometry,and then the changes of subcellular structures were observed by electron microscope.Results The proliferation inhibition rates in hyperthermia,TL,TL combined with hyperthermia groups were 21.2%,28.5% and 54.5%,respectively;the proliferation inhibition rate in TL combined with hyperthermia group was higher than those in hyperthermia and TL groups(P
