BACKGROUND: Bone marrow mesenchymal stem cells are characterized by wide sources and low immunogenicity. Especially, these cells are easy to import and express foreign genes, and thus have obvious superiorities as anti-tumor gene therapy vectors. OBJECTIVE: To investigate the effects of interleukin-12 gene modified bone marrow mesenchymal stem cells on the proliferation, cell cycle and apoptosis of ovarian cancer cells. METHODS: Interleukin-12 recombinant adenovirus vector was used to transfect bone marrow mesenchymal stem cells. Then, the expression of interleukin-12 mRNA and protien in transfected bone marrow mesenchymal stem cells was detected by RT-PCR and western blot assay, respectively. The level of interleukin-12 in cell supernatant was determined by ELISA. The SKOV3 cells were co-cultured with the supernatant of bone marrow mesenchymal stem cells transfected with (transfection group) or without (control group) interleukin-12 recombinant adenovirus vector. The proliferation of SKOV3 cells was determined by MTT assay. Flow cytometry was used to detect the cell cycle and apoptosis of SKOV3 cells. RESULTS AND CONCLUSION: RT-PCR and western blot results showed that interleukin-12 mRNA and protein were expressed in transfected bone marrow mesenchymal stem cells, but not found in empty vector group and blank control group. ELISA results showed that the content of interleukin-12 in the supernatant of bone marrow mesenchymal stem cells was (68.78±12.35) μg/L in the interleukin-12 transfection group after 48 hours culture, and no interleukin-12 expression was detected in the empty vector group and the blank control group, Interleukin-12-transfected bone marrow mesenchymal stem cells significantly inhibited the proliferation of SKOV3 cells, and the proliferation inhibition rate was increased with time (P < 0.05). The proportion of G1-phased SKOV3 cells was higher in the transfection group than in the control group (P < 0.05), and the percentage of G2-phased SKOV3 cells was lower in the transfection group than in the control group (P < 0.05). The apoptosis rate of SKOV3 cells in the transfection group was higher than that in the control group (P < 0.05). Our experimental findings indicate that bone marrow mesenchymal stem cells transfected with interleukin-12 recombinant adenovirus vector can express interleukin-12, inhibit the proliferation and induce apoptosis of ovarian cancer cells.

Objective To study the clinical values of polyvinyl alcohol chemoembolization and bronchial arterial infusion(BAI) in interventional therapy of central bronchogenic carcinoma.Methods 45 pathologically proved cases of central bronchogenic carcinoma in mid or late period were randomly divided into two groups(control group in 24 cases and experimental group in 21 cases).After detecting the nourishing arteries of bronchogenic carcinoma with angiography,the treating processes were performed.Control group : anticancer drugs were poured into bronchial artery.Experimental group : the feeding arteries of tumors were co-axially superselective catheterized with microcatheters,the anti-neoplasm agents were poured into everyone of feeding arteries according to the blood supply,then the feeding arteries were embolized by polyvinyl alcohol.Results Control group : the obvious effective rate(CR+PR) was 50%.Experimental group:the obvious effective rate was 90.4%.Two cases in control group obtained the chances of radical operation and chemotherapy were performed after operation,the other 22 cases were undergone synthetic treatment.Seven cases in experimental group obtained the chances of radical operation and chemotherapy were performed after operation,14 cases were undergone synthetic treatment.Three cases in control group died and none of in experimental group died in the follow-up of 2~24 months.Conclusion The short-term effect of polyvinyl alcohol embolization is better than those of BAI for interventional therapy of central bronchogenic cancer,but the long-term effect needs a large number of cases to access the real clinical value.

Conclusions Cancer patients′ positive psychological capital and the quality of life both need to be improved; Cancer patients′ psychological capital are closely related to the quality of life and we should pay attention to improve the patients′psychological capital so as to better their quality of life during the care process.

BACKGROUND:Gene engineering plays an important role in the process of human malignant tumor treatment, and adenovirus vectors for gene therapy are commonly used. In recent years, lactoferrin is found to exert important effects on the occurrence, development and metastasis of a variety of tumors. However, little is reported on the in vivo expression of adenovirus vector mediated lactoferrin in the human body.OBJECTIVE:To investigate the effect of adenovirus mediated human lactoferrin (Ad-hLF) on proliferation and apoptosis of cervical cancer stem-like cells.METHODS:Primary cervical cancer cells from mice were cultured in vitro to sort cervical cancer stem-like cells using SP method. Afterwards, the stem-like cells were divided into three groups, blank control group, empty vector group, and Ad-hLF group, followed by transfection with nothing, Ad-GFP and Ad-hLF, respectively. After transfection, MTT assay was used to detect the proliferation of cervical cancer stem-like cells; scratch-wound assay was employed to detect the migration of cervical cancer stem-like cells; western blot assay was used to determine the expression of lactoferrin in cervical cancer stem-like cells; and Annexin V-FITC/PI was used to detect cell apoptosis.RESULTS AND CONCLUSION:Compared with the blank control and empty vector groups, Ad-hLF significantly inhibited the proliferation of cervical cancer stem-like cells and reduced the number of scratched cells, while the cell apoptosis increased in the Ad-hLF group (P < 0.05 or P < 0.01). These findings indicate that the recombinant adenovirus vector mediated lactoferrin Ad-hLF for transfection of cervical cancer stem-like cells can be stably expressed in cervical cancer stem-like cells, and can inhibit the proliferation, increase apoptosis and reduce migration of cervical cancer stem-like cells.
