Objective To evaluate the palliative effect on pain relief in patients with multiple bone metastases treated with 89SrCl2 together with Sodium Ibandronate,Sodium Ibandronate alone and 89SrCl2 alone. Methods Eighty-four patients with bone pain secondary to bone metastases were divided into three groups. Thirty patients were treated with combined 89SrCl2 and Sodium Ibandronate,26 with 89SrCl2 alone and 28 with Sodium Ibandronate alone. The x2 test was used in data analysis. Results The overall palliative pain relief rate in the combined treatment group was 96.6 % (29/30). For the groups using Sodium Ibandronate or 89SrCl2 only,the palliative rates were 71.4% (20/28) and 73.1% (19/26),respectively. There are statistically significant differences between the combined treatment group and the other 2 groups with single treatment modalities in the overall palliative pain relief rate (x2 = 7.497 ),in terms of improvement in (1) whole body Karnofsky performance status (KPS) score (80.0% (24/30) vs 50.0% (14/28)/53.8% (14/26),x2 =35.476) and (2) focal palliative rate (47.6% (50/105) vs 11.2% (11/98)/22.2% (20/90),x2 =6. 564,all P ＜ 0. 05 ). Conclusions Combined treatment with 89 SrCl2 and Sodium Ibandronate is more effective than single treatment modalities to relieve bone pain seccondary to multiple bone metastases.

AIM: To study on antisense oligoncleotides as inhibitor of human acute promyelocytic leukemia (HL-60) proliferation and C-myc protein expression. 　METHODS: Oligonucleotides with different lengths (18-21 mer) complementary to the definite regions of C-myc mRNA, modified groups (with S replaced O in internucleotide phosphate linkage) and unmodified ones (with natural internucleotide phosphate linkage) were designed and synthesized. These olignucleotides were tested for their activity on HL-60 cell and also for their toxicity on normal lymphatic cells of human. 　RESULTS: It was found that two of the oligonucleotides complementary to 5′-44-61 and 5′-556-576 the regions of C-myc mRNA exhibited great inhibitory effects (59.5 % and 62.7 %) on growth of HL-60 cells for a definite time. And no toxicity of the two antisense oligonucleotides was found on normal lymphatic cells of human. 　CONCLUSION: The sequence of antisense oligonucleotides complementary to 5′-44-61 of C-myc mRNA was designed newly by us may be turned into inhibitory medicine of HL-60 cells.

Objective To observe the expression of survivin and Aurora B in human pancreatic cancer BXPC3 cells after the treatment of sulindac and to explore the potential mechanism. Methods MTr assay was used to determine the effect of sulindac on the proliferation of the BXPC3 cells. RT-PCR was used to detect the expression of mRNA level of survivin and Aurora B, western blot was used to detect protein expression of survivin and Aurora B Thr-232. Cell cycle and apoptosis were detected by flow eytometry (FCM). Results The BXPC3 cells were inhibited by sulindac in a dose and time-dependent manner; the expression of mRNA of survivin and Aurora B were both significantly decreased from 1.5644 and 0.6554 to 0. 4372 and 0.1132 (P< 0.01), the expression of survivin protein and the phosphorylation of Aurora B Thr-232 were also decreased from 1.2735 and 0.4680 to 0.2126 and 0.2546 (P<0.01); the proportion of cells in the G0/G1 phase was increased from (56.65±1.93)% to (70.58±3.21)% (P<0.01). Conclusions Sulindac had inhibitory effects on the growth of BXPC3 cells, the possible mechanism was via decreasing the expression of survivin which depressed the activity of Aurora B, then the CPC was influenced. The most of the cells were blocked in the G0/G1 phase, and the cells' mitosis was inhibited.

Objective To investigate the effect of genistein on Notch-1, SHH and HHIP gene expression and on the cell cycle and proliferation of of BxPC3 cells. Methods Human pancreatic cancer cell line BxPC3 was cultured. The BxPC3 cells were treated with genistein and then the total RNA and protein were extracted. RT-PCR was used to detect the expression of Notch-1 mRNA, SHH mRNA and HHIP mRNA. Noteh-1 and SHH protein was determined by western blotting. MTT assay was used to detect proliferation of BxPC3 cells. The cell cycle of BxPC3 cells was measured by Propidium iodide (PI) and flow cytometry. Results The inhibiting rate was 67.17%±2.32% when BxPC3 cell lines were treated by 20μg/ml genistein for 48 hours. Notch-1 mRNA was down-regulated from 2.454±0.068 to 1.304±O.169 ; SHH mRNA was down-regulated from 0.959±0.023 to O.472±0.077 ; HHIP mRNA was up-regulated from 0.625±O.158 to 1.761±0.121.
