This study is to investigate the effect of ethyl gallate on invasion capabilities and its mechanism of breast cancer MDA-MB-231 cells. Using cell adhesion and transwell assay, separately, the effects of ethyl gallate on the invasion of MDA-MB-231 cells were measured. The Akt-NF-κB signal pathway protein expressions were analyzed with Western blot. Also, the mRNA levels of MMP-9 and MMP-2 were analyzed by RT-PCR. Ethyl gallate inhibited the abilities of motility, adhesion and invasion of breast cancer MDA-MB-231 cells in vitro (P<0.05), inhibited the mRNA levels of MMP-9, MMP-2, phosphorylation of AKt and protein expression of NF-κB. It is concluded that ethyl gallate can inhibit the abilities of invasion of breast cancer in vitro by inhibiting the mRNA levels of MMP-9/MMP-2, phosphorylation of Akt and protein expression of NF-κB.

Objective To evaluate and summarize a new way of forward intensity modulated radia- tion therapy (IMRT) plan for nasopharyngeal carcinoma with 3Dmulti-leaf collimator (MLC) planning sys- tems is practised routinely in our department.Methods From September 2000 to July 2003 and November 2005 to March 2006,78 patients with nasopharyngeal carcinoma who were treated with eonformal radiothera- py used CT simulation for localizing,then doctors supervised the delineation of the planned tumor volume (PTV),gross tumor volume (GTV) and other sensitive organs on ACQsim workstation,and then sent the CT imagines to ELEKTA Precise Plan by DICOM RT Ethernet.Then,the physicists take over the responsibility of all directions of beam projection according to these organs and PTV shape,and completed the IMRT plan by manual correction making and the optimization of fields or segments shaped with forward 3D planning sys- tem.Results To analyse all the patient's dose distributions taking conformal radiotherapy in our hospital, we found the dose distribution and DVH data excellent,even better than the inverse planning of nasopharyn- geal carcinoma.Conclusions Intensity modulated radiation therapy (IMRT) is an advanced radiotherapy technique.A very good IMRT plan of nasopharyngeal carcinoma by forward planning can be obtained with 3D multiple leaf collimator (MLC) planning system.This planning method is more flexible,but the radia- tion physicists should be very much experienced in professional skill.

S801 leukemic cell line established by our department was used as cells for interferon (IFN) induction and stimulating induction. S801 cell culture of concentration of 5-8x10~6 cells/ml was used for IFN induction and IFN titer of 3.55 Lg IU/ml was obtained by classical procedure. The IFN titer obtained S801 cell cultures after pretreatment with Ciwujia eleutherosides B. D and E or polysaccharide (PES) combined with priming procedure,then using Sendai Virus as an inducer was 10-20 times higher than that in cultures without any pretreatment. These Chinese medical herbs may be the ideal IFN helpinducers. This cell line may be applied for IFN production.
