To explore the effects of Lichong Shengsui decoction on cycle and apoptosis of ovarian cancer SKOV3 cells.Methods:Taking ovarian cancer SKOV3 cells as the research objects，the inhibitory effect of different concentrations of cisplatin on SKOV3 cells was detected by CCK-8 method.The apoptosis of SKOV3 cells was detected by Annexin V-FITC method.The cycle changes of SKOV3 cells was detected with the cell cycle and apoptosis detection reagents，and the ratio of CD44+CD117+ cells in SKOV3 cells was detected by flow cytometry.Results:Compared with the blank group，the apoptosis rate of SKOV3 cells in the cisplatin group was significantly increased in the 24 h and 48 h.The proportion of cells in G0/G1 phase was decreased，the proportion of cells in S phase cells was increased，and the proportion of CD44+ CD117+ cells was significantly increased.Compared with the cisplatin group，the apoptosis rate of SKOV3 cells in Lichong Shengsui Decoction combined with cisplatin was significantly increased in the 24 h and 48 h.The proportion of cells in G1 phase was decreased，the proportion of cells in S phase was increased，and the proportion of CD44+CD117+cells was significantly decreased.Among them，the middle dose of Lichong Shengsui Decoction combined with cisplatin group had the strongest effects.Conclusion:Lichong Shengsui Decoction has anti-tumor effect，and its mechanism maybe increase the apoptosis of ovarian cancer SKOV3 cells by cisplatin，regulate cell cycle arrest and decrease the number of stem cells in ovarian cancer SKOV3 cells.
