Objective To investigate the mechanism of extremely low frequency electromagnetic field (ELF-EMF) and X-ray irradiation on liver carcinoma cell lines BEL-7402. Methods Liver carcinoma cell lines BEL-7402 had been incubated with ELF-EMF (100 Hz, 0.7 mT, 30 min, 3 days) after X-ray irradiation at different doses (0, 2, 4, 6, 8,10 Gy). The cells were observed on morphologic changes with scanning electron microscope. Flow cytometry and gene microarray were used to investigate the mechanism of cell apeptosis. Results ELF-EMF plus X-ray induced apoptosis on BEL-7402 was observed under scanning electron microscope.When X-irradiation was 2, 4, 6, 8 and 10 Gy, the apoptosis ratios of combined group and only X-irradiation group were 10.0%, 14.5%, 4.3%, 5.1%, 7.1% and 0.1%, 8.1%, 0.1%, 0.4%, 2.2% (P < 0.05) on flow cytometry. The result of microarray indicated that 1465 genes were up-regulated and 1108 down*regulated in the ELF-EMF plus X-ray group in comparison with the control group. The change rates of 110 apoptosis related genes were above 2 times, which including 71 up-regulated and 39 down-regulated. Gene microarray showed that ELF-EMF and X-ray irradiation had a mainly effect on different gene of apoptosis paths (CDC25 and CHKI, ATM, p38, PTEN, p53, G1/S, Fas, G2/M, Cell Cycle, Apoptosis and Caspase). The same genes of ELF-EMF plus X-ray group were showed 13 in ELF-EMF group and 42 in X-ray group. Conclusions Apoptosis paths were significantly different between ELF-EMF and X-irradiation. ELF-EMF cooperates with X-irradiation on inducing BEL-7402 cell apoptosis.

Objective To evaluate the effects of endogenous NO on the chemosensitivity of human breast cancer cell. Methods MCF-7 cells were cultured as monolayer, incubated with cytokine IL-1β. The pro-duction of NO was detected by NO assay. The expression of iNOS protein was measured by Western blotting. Establishing control group and experimental group, the chemosensitivity of MCF-7 cells incubated by L-NMMA and L-Arg to ADM and 5-Fu was studied by MTT assay. Results There was a positive correlation of dose-dependence between NO production and IL-1β concentration. MCF-7 cells expressed plenty of iNOS by induetion of IL-1β. There was no significant difference on iNOS whether L-NMMA and L-Arg existed or not. Incubating MCF-7 cells with 0. 5 μmol/L or 1 μmol/L ADM, the survival rate of experiment group was remarkablely decreased(P < 0.05) ; L-NMMA significantly increased survival rate of experiment group(P < O. 05) ; L-Arg decreased survival rate of experiment group(P < 0.05). Conclusion The induction of IL-113 in MCF-7 cells can increase the production of endogenous NO, which increases MCF-7 cells' sensitivity to chemotherapy.

Objective To observe the therapeutic efficacy of continuous arterial infusion chemotherapy combined with radiofrequency hyperthermia in the treatment of patients with advanced colorectal cancer. Methods A total of 21 advanced colorectal cancer patients with various distant metastasis were treated by the combined continuous intra arterial infusion chemotherapy and radiofrequency hyperthermia. For the chemotherapy, a dose of 200mg/m 2 surface body area of calcium folinate (CF) was given for 1 to 3 days. 80mg/m 2 of cisplation was infused intravenously for the first day and replaced by etoposide Vp 16, 60mg/m 2 for 1～3days in patients with renal dysfunction. For intra arterial infusion, a dose of 500mg/m 2 5 FU 2 was given for 72 hours. For patients with liver metastases, chemoembolization(ADM 30mg/m 2+MMC 6mg/m 2 mixed with ultra liquefied lipiodol) was carried out. Radiofrequency hyperthermia with a frequency of 41MHz was performed on the second day after chemotherapy. Results Response rates were assessed by CT scan and ultrasonography. The overall response rate of the cases was 66.67%. No serious side effect or complication was found in the course of chemotherapy. Local pain and lipid nodule were occasionally observed in some patients after hyperthermia. Conclusion Continuous intra arterial infusion chemotherapy in combination with radiofrequency hyperthermia is an useful and safe method for the treatment of patients with advanced colorectal cancer.

Objective: To explicit whether miR-200b can suppress the proliferation and invasion by targeting CD133, and to explore a molecular mechanism that miR-200b plays a role in tumor suppression in glioma. Methods: The CD133 3'-untranslated region (3'-UTR) mRNA-luciferase reporter vector was constructed and the dual-luciferase reporter gene assay was employed to examine the effect of miR-200b on activity of luciferase. U251 cells were transfected with miR-200b mimics and CD133-small interfering RNA (siRNA) (as a positive control) by LipofectAMINE 2000, and the expressions level of CD133 protein was detected by Western blotting. The inhibition effects of CD133 on cell proliferation and invasion were observed after CD133 siRNA were transfected into U251 cells. U251-SC cell mammosphere assay was performed after cotransfection with miR-200b mimics and CD133 siRNA. Results: miR-200b could bind to the 3'-UTR of CD133 and inhibit the activity of luciferase. CD133 protein expression was significantly down-regulated when miR-200b was overexpressed in U251 cells. Overexpression of miR-200b inhibited the invasion of U251 cells. Overexpression of miR-200b antagonized a role of proliferation and invasion in U251 cells. Overexpression of miR-200b reduced mammosphere number and the size of glioma stem cells. Conclusion: miR-200b can suppress cell proliferation and invasion by targeting CD133 in glioma. Copyright © 2014 by TUMOR.
