Results In RT-PCR analysis of the peripherial blood, 45%(18 out 40) of CRC patients, 10%(2 out 20) of CRP patients were positive for CEA mRNA, respectively. All 40 healthy individuals were negative for CEA mRNA expression. The detection of CEA mRNA was significantly correlated with TNM stage of CRC patients, while there were no significant relationship between the CEA mRNA expression and the malignant extent of cell differentiation.

Results: A 2-AAF/PH model was successfully established to activate the oval cell compartment in rat liver. HOC appeared mainly in periportal areas and could extend into the liver parenchyma. The volume of oval cells was about as big as one forth to one sixth of normal liver cells, with a oval-shaped nucleus and high nuclear/cytoplasm ratio.

In the in vivo study, 100 ICR mice were randomly assigned to 5 groups after paired by body weight as following: Group N (negative control group, peritoneally injected by saline daily); Group C (positive control group, peritoneally injected by D-galactose and saline daily); Group L, M, and H (peritoneally injected by D-galactose and intragastric administered with TP at 100, 200, 400 mg/day, respectively). Mice were sacrificed for histology and biochemistry studies after 8 weeks.

After the cell growth curves was recorded, RPE cells of the 3-5th passages were utilized. 2、Three different siRNA (siRNAl,siRNA2,siRNA3) targeting against human cx43 gene and one negative control siRNA were designed and transfected into cultured human RPE cells via liposome reagent. The most effective siRNA can be determined by semi-quantitative reverse transcription PCRRT-PCR. 3、To the most effective siRNA, after transfected into human RPEs with different concentration, the cellular proliferate activities were messured by MTT colorimetry ; the percentages of RPE in different cell circle phase was assayed by FCM; the changes of phenotypical properities were observed with SCM; the protein expression of cx43 was studied through immunocytochemistry stain and Weston blot; the communication intercellular was calculated with FRAP; and the ability of recovery was assessed by using an in vitro wound healing model.4、The total proteins of siRNA1 and RPE were seperated by two-dimensional gel electrophoresis and visualized by silver staining. Proteins with significant expression alterations were selected and their peptide mass fingerprints (PMFs were obtained by matrix-assisted laser desorption/ionization time of flying mass spectrometry (MALDI-TOF-MS).The PMFs were used to search NCBInr database by Auto MS-Fit software.
