ABSTRACT
Objective To investigate the expression of astrocyte elevated gene -1( AEG-1) and matrix metallopeptidase 9(MMP-9)in colorectal tissues and evaluate its correlation with clinical pathologic factors of colorectal cancer.Methods AEG-1 and MMP-9 expression in normal colorectal mucous (n=45),low-grade adenoma(n=31),high-grade adenoma(n=15)and colorectal carcinoma(n=146)were examined by immuno-histochemistry .Statistical analyses were applied to test the significance of its expression .Results AEG-1 ex-pression levels were gradually elevated in normal tissues ,low-grade adenoma ,high-grade adenoma and colorec-tal carcinoma respectively .Furthermore ,there was a similar trend for MMP -9from normal mucous to adenoma and carcinoma .Statistical analysis revealed that AEG -1 expression was markedly correlated with the UICC stage,T classification,N classification,M classification,and histological differentiation in the colorectal cancer pa-tients,but not with age,gender,tumor location and tumor size.In addition,AEG-1 expression was positively cor-related with the MMP-9 expression in colorectal cancer .Besides,those patients with high AEG-1 and MMP-9 levels had shorter survival time ( P<0 .05 ) .Conclusion AEG-1 may be involved in carcinogenesis and pro-gression of colorectal carcinoma and can be a novel prognostic biomarker in patients with colorectal carcinoma .
ABSTRACT
Objective:To investigate the effects of Chinese Medicinals with right supporting and phlegm transforming actions on albumin synthesis and secretion of fibrous hepatic cells of rat in vitro. Methods: Amygdalin, the water soluble extract of Radix Salviae Miltiorrhizae, lordyceps, and colchicine were used to act on fibrous hepatic cells of rat produced by primary monolayer culture in vitro. The results were determined by ELISA method. Results: Besides colchicine, the others amygdalin and cordyceps. Cordyceps, the water soluble extract of Radix Salviae Miltiorrhizae) showed the obvious raising actions on albumin synthesis and secretion of fibrous hepatic cells of rat ( P
