BACKGROUND: Nerve growth factor (NGF) and myelin-associated glycoprotein (MAG) can promote the repair of peripheral nerve. However, increasing the expression of NGF and MAG in the injured peripheral nerve by transgene technology has not been reported.OBJECTIVE: To investigate the expression of NGF and MAG after adenovirus (Ad) mediated transfection in the injured sciatic nerve in rats.METHODS: Forty Sprague-Dawley rats were randomly divided into normal, model, Ad, NGF and NGF-MAG groups. Sciatic nerve injury models were established in the latter four groups by cutting and suturing the right sciatic nerve. Afterwards, the rats in each group were subject to the intramuscular injection of normal saline, normal saline, Ad (1×108 PFU), Ad-NGF (1×108 PFU), and Ad-NGF-MAG (1×108 PFU), respectively, once every 2 days, for consecutive three times.RESULTS AND CONCLUSION: The expression level of NGF in the rat sciatic nerve in the Ad and normal groups was significantly higher than that in the NGF and NGF-MAG groups (P < 0.05). Compared with the Ad, NGF and normal groups, the expression level of MAG in the NGF-MAG group was significantly increased (P < 0.05). To conclude, the Ad-mediated NGF and MAG after double gene transfection were expressed effectively in the injured sciatic nerve in rats.

Objective To evaluate the effects of nursing intervention on the beliefs and behavior of early detection of breast cancer. Methods Four communities in Shanghai were selected by convenient sampling process. Then these four communities were randomly assigned to intervention group and control group. One hundred and eighty women who met the criteria of this study were selected from each group by convenient sampling process.Altogether 739 women were recruited. In intervention group,a one-year nursing intervention guided by health belief model was implemented,such as health education seminars,telephone follow in the third,sixth,and ninth months,and flyers of breast health care in the sixth month. Control group only received conventional education. Results After intervention women became aware of breast cancer (B=0.210,P<0.01),perceived more benefits from attending early breast cancer detection (B=0.105,P<0.01),and less difficulties in attending the activities of early detection of breast cancer (B=-0.086,P<0.05). The number of women who performed breast self-examination once per month increased and more women received clinical breast examination (OR=3.0946) and mammogram after intervention (OR=2.746). Conclusion The nursing intervention,guided by health belief model,is helpful to improve women's beliefs and behaviors of breast cancer detection.

In order to investigate the inhibitory effects of Endostar (rh-endostatin, YH-16) in combination with radiotherapy on lung adenocarcinoma A549 in mice and the interaction mechanisms of combined therapy, the transplantation tumor models of A549 lung adenocarcinoma were established. When the largest diameter of tumor reached 1.0 cm, all nude mice were randomly divided into 4 groups: Endostar group, radiotherapy group, radiotherapy plus Endostar (combined treatment) group, and control group (n=6 in each group). The largest diameter and the vertical diameter of tumor were measured at different time points. At the 16th day, mice were executed, and the tumors were applied to analysis of rate of tumor cell apoptosis, and the expression levels of basic fibroblast growth factor (bFGF) mRNA were detected by reverse transcription-polymerase chain reaction (RT-PCR) and those of vascular endothelial growth factor (VEGF) by immunohistochemistry. The results demonstrated that the rate of tumor inhibition in combined treatment group was higher than that in other groups. And the rate of tumor cell apoptosis in combined treatment group was also higher than that in other groups. Meanwhile, the levels of bFGF mRNA and VEGF expression in combined treatment group were lower than those in other groups. It was concluded that Endostar obviously enhanced the curative effectiveness of radiotherapy on lung adenocarcinoma A549 in mice. The underlying mechanisms may involve the down-regulation of bFGF mRNA and VEGF expression to inhibit angiogenesis by Endostar and the cooperative effect of Endostar and radiotherapy to synergistically promote tumor cell apoptosis. And Endostar inhibits angiogenesis by down-regulating the expression of bFGF mRNA and VEGF.

Objective To value the significance of TGFBR2 gene in mediating HepG2 cell proliferation by RNA interference technology. Methods Three kinds of siRNAs targeting TGFBR2 gene were designed, synthesized and transfected into HepG2 cells via lipofetamine2000. Among three kinds of siRNAs, only the one with the most interference efficacy was selected and the correspondent DNA sequence was inserted into plasmid pEGFP-N3. Then the recombinant plasmid of siRNA-pEGFP-N3 was transfected into HepG2 cell and western blot was used to detect the protein level of TGFBR2. Then, TGF-β1 was used to stimulate HepG2 cells with or without siRNA interference and proliferation of HepG2 cells was observed. Results Among these three siRNAs, siRN-1 appeared to be the most effective. After stimulated by 5ng/mL TGF-β1, proliferation of HepG2 cells showed a marked increase in siRNA-1 group compared with blank and siRNA-NC groups (P<0.05). For all that, the proliferation rate was still lower than that in normal HepG2 cell group without TGF-β1 stimulation. Conclusion By silencing TGFBR2 gene, inhibition of TGF-β1 signaling pathway to HepG2 cells could be decreased, thereby enhancing the cell proliferation.
