RESUMEN
Objective To observe the effects of Banxia Xiexin Decoction (BXD) containing ser- um on proliferation, invasion and metastasis of in vitro human gastric cancer peritoneum cell strain GC9811-P (which has high metastatic potential). Methods BXD containing serum was prepared. GC9811-P cells were inoculated in the E-Plate 96 and CIM Plate 16, and then 0, 25, 50, 100 µL/mL BXD containing serums were added respectively. Meanwhile, GC9811-P cells were stained by Diff-Quik stai- ning method. Inhibition of BXD containing serum on cell index (CI) for proliferation of GC9811-P cells, invasion and metastasis were observed by real time cellular analysis (RTCA) and Diff-Quik staining method. Results BXD containing serum could obviously inhibit the proliferation of GC9811-P cells. The Cl approximated to 0 after 70 h. Most stained Diff-Quik cells died. Cell migration curve showed that 25, 50, 100 µL/mL BXD containing serums could obviously inhibit the capacities for cell migration of GC9811-P cells in concentration dependent manner. The number of migration cells was reduced more obviously, as com- pared with 0 µL/mL BXD containing serum (P <0. 05). Conclusion BXD containing serums could inhibit the proliferation, invasion and metastasis of GC9811-P cells, which might be associated with blocking peritoneal metastasis of gastric cancer.
