Objective To evaluate method of CT simulation (CT sim) in the treatment planning setup of esophageal carcinoma. Methods From Dec.1999 to Jun.2002, 49 patients with pathologically proved esophageal carcinoma were analyzed. All patients underwent CT sim and treatment planning was configured with three symmetrical fields in the isocenter mode. A few comparisons have been made between CT sim and conventional simulation (Con sim) in the treatment planning setup. Results The difference in isocenter position were observed between CT sim and Con sim with 3～18 mm.When the esophageal lumen was taken as portal center, the 90% isodose curve in 42.8%(21/49) of patients were able to cover the whole lesion. When taking the tumor as the portal center, the whole lesion of all patients was totally covered by the 90% isodose curve. Conclusion The CT sim has an advantage in the delineation of lateral extension of esophageal tumor than the Con sim .Selection of irradiation portal should be done according to the size the silhouette of the tumor.

Objective To determine whether focal adhesion kinase (FAK) signal pathway was involved in migration of hepatocarcinoma cells by inhibiting focal adhesion kinase (FAK) phosphorylation in HepG2 cells with focal adhesion related nonkinase (FRNK). Methods The recombinant of FRNK and pEGFP-C2, an endogenous inhibitor of FAK activation,was transfected into HepG2 cells. HepG2 migration was examined by transmembrane assay. FAK and phosphatinositol 3-kinase (PI3-K) phosphorylation were detected by immunoprecipitation method. Confocal scanning microscopy was used to verify nuclear translocation of nuclear factor-kappa B (NF-?B). Results The transfection of FRNK recombinant plasmid could inhibit HepG2 migration, FAK and PI3-K phosphorylation decreased by 50.2 percent and 39.5 percent respectively. Furthermore, NF-?B translocation was down-regulated from 3.495?0.227 to 1.182?0.106. Conclusion These results suggested FAK was a main signal pathway in mediating HepG2 migration. Over expression of FRNK might inhibit signal transduction of FAK via depression of the phosphorylation of PI3-K and NF-?b activation, resulting in the decrease in migration of hepatocarcinoma cell.

OBJECTlVE To investigate the correIation between baicaIin metaI(Ni2+,Co2+,Cu2+) compIexes(BmC)with their anti-tumor activity and the abiIity of BmC to bind to hepatoma ceII DNA. METHODS The cheIating Iigand method was used to synthesize BmC,and the composition and struc-ture of BmC were characterized. mTT,PI staining method and AnnexinⅤ-FITC doubIe staining method were used to anaIyze the effect of BmC on SmmC-7721 ceII proIiferation,cycIe and apoptosis,and to expIore their cytotoxic effect on SmmC-7721 ceIIs in combination with morphoIogy. With DNA extracted from hepatoma ceIIs as a target,cycIic voItammetry and AC impedance were used to study the interaction of BmC with DNA. The interaction mechanism between BmC and DNA was expIored. RESULTS Three new types of BmS were successfuIIy prepared. The moIecuIar formuIas of compIexes were Na2 Ni(C21 H16 O11 )2·10H2 O,Na2 Co(C21 H16 O11 )2·8H2 O,and Na2 Cu(C21 H16 O11 )2·8H2 O,respec-tiveIy. CeII proIiferation and morphoIogy detection reveaIed that BmC 6.25-100 mg·L-1 treatment for 24, 48 and 72 h couId inhibit SmmC-7721 ceII survivaI. BmC cytotoxicity was Iisted as foIIows:baicaIin-cop-per( BC-Cu)﹥ baicaIin-cobaIt( BC-Co)﹥ baicaIin-nickeI( BC-Ni)﹥ baicaIin( BC),in a concentration-dependent manner(P﹤0.01)and time-dependent manner(P﹤0.01). According to the resuIts of ceII cycIe and apoptosis detection,BmC retarded the growth of ceIIs from G0 / G1 phase into S phase or G2 / m phase whiIe inducing apoptosis of SmmC-7721 ceIIs. The resuIts of eIectrochemicaI anaIysis showed that BmC and hepatoma SmmC-7721 ceII DNA formed a non-eIectroactive supermoIecuIar compound through the mixed-mode of eIectrostatic interaction and insertion effect. The binding parameters were obtained:the binding number m = 2,the binding constant βBC = 2.77 ×106 L·moI-1 ,βBC-Ni = 5.46 ×106 L·moI-1 ,βBC-Co =7.74×106 L·moI-1 ,and βBC-Cu =1.21×107 L·moI-1 . The abiIity of BmC to bind to DNA was signifi-cantIy enhanced by BC compIexes with metaI ions,and their abiIity was Iisted as foIIows:BC-Cu﹥BC-Co﹥BC-Ni﹥BC. CONCLUSlON BmC shows cytotoxicity by bIocking the ceII cycIe,inhibiting ceII proIiferation and motivaing apoptosis. The abiIity of BmC to bind to DNA is consistent with its cytotoxicity. BmC,after binding to ceII DNA,wiII bIock DNA repIication,inhibit ceII proIiferation,Iead to ceII apoptosis,and exhibit anti-tumor activity.
