ABSTRACT
Objective To study the effects of cinobufacin(cino) combined with fluorouracil(5-FU) on inhibiting proliferation and inducing apoptosis of human gastric carcinoma cells in vitro. Methods The experiment was divided into control group,cinobufacin group,5-FU group and cino+5-FU group. Cell morphological variation,cell inhibitory rate, cell cycle and ratio of apoptotic cell of human gastric carcinoma cell line BGC-823 were studied by cell culture, inverse microscopy, fluoroscopy, MTT assay and flow cytometry on different concentrations of cino and 5-FU. Results Cino could markably inhibit proliferation of human gastric carcinoma cells in time-and dose-dependent response. The cino+5-FU group inhibited the rate of proliferation of BGC-823 cells was significantly more than either cino or 5-FU alone group(P
ABSTRACT
3 years. Conclusions Regional infusion chemotherapy via selected artery with a pump is an efficient way for unresectable cardic and fundus cancer of stomach, which can improve the survival period of patients. Moreover, some patients could get secondary resection.

ABSTRACT
Objective To evaluate the value of regional infusion chemotherapy for prevention of local (recurrence) and hepatic metastasis after radical resection of gastric carcioma.Methods 352 patients with (gastric) carcinoma undergoing radical operation were preoperatively randomly divided into 2 groups:Regional (infusion) chemotherapy(treatment group,184 cases) and peripheral venous chemotherapy(control group,168 cases).Results 328 cases(93.2%) were followed-up for 3 to 6 years,and 24 cases were lost to follow up.The 1-,3- and 5-year survival rate was 95.7%,78.3% and 46.3%,respectively,in the (treatment) group,and 86.8%,48.2% and 22.0%,respectively in the control group.The local recurrence rate and hepatic metastasis rate was 9.2% and 12.5%,respectively,in the treatment group; and was (22.0)% and 26.8%,respectively,in the control group.Conclusions Regional infusion chemotherapy is (effective) for prevention of local recurrence and hepatic metastasis after radical operation for gastric carcinoma.It is better than peripheral venous chemotherapy and has less toxic side effects.
