Multiparameters diagnostic models were constructed based on above profiling and routine ***:A biantennary glycan(NG1A2F,peak 4) was found to be decreased in HCC and increased in liver fibrosis,while a branching triantennary glycan(NA3Fb,peak 9) was increased in HCC and decreased in liver *** efficacy of the log ratio of these two N-glycan structure abundances[log(p9/4)]was similar to AFp in differentiation HCC from *** accuracy and sensitivity of the diagnostic model combining AFp and N-glycan markers(Cscore B)were increased 7-10%compared to that of AFp. Log(p9/4) was more efficient in monitoring the progression of HCC in regarding to vascular invasion with improved specificity(16%) and accuracy(8%) compared to that of AFp. CONCLUSIONS:The branchingα(1,3)-fucosylated triantennary glycan and the biantennary glycan are potential as N-glycan *** diagnostic models based on the N-glycan markers and AFp improve the efficacy in HCC diagnosis and progression monitoring.

Objective To acquire oval cells （progenitor stem cells ） from adult rat liver of different models including diabetic rats. Methods Thirty Sprague-Dawley （ SD ） rats were divided into 5 groups randomly： control, 2-acetylaminofluorene （ 2-AAF ）, 2-AAF ＋ partial hepatectomy （ pH ）, 2-AAF ＋ carbon tetrachloride （ CCl4 ）, and diabetic groups. As two-step collagenase perfusion protocol of Seglen, oval cells were isolated by percoll density gradient centrifugation. Thy1. 1 positive cells were sorted by flow cytometry, and then cultured in Dulbecco＇s minimum Eagle＇s medium （DMEM）. Immunofluorescence staining was applied to labelling Thyl. 1. results Different rates of Thy1.1 positive oval cells were found in different rat model groups ： 0. 5 % in 2-AAF, 0. 3% in 2-AAF ＋ pH, 0. 2% in 2-AAF ＋ CCl4, 0. 1% in diabetic, and 0. 0% in control. Isolated cells adhered to plate with fusiform or polygon as epithelial cells. Conclusion progenitor stem cells exist in injured liver tissue including those from diabetic rats.

aiM： To explore the relationship between acetylation of histone in total chromatin and p21^WAF1 expression regulation in human colorectal carcinoma. METHODS： We analyzed the expression of tumor suppressor gene p21^WAF1 mrNA by rT-pCr or realtime pCr in 33 samples of colorectal cancerous tissue, corresponding para-cancerous tissue and normal colorectal mucosa, and also examined the level of acetylated histone H3 in total chromatin using Western blotting. rESULTS： The expression level of p21^WAF1 mrNA was significantly lower in colorectal cancerous tissue from 33 patients than in para-cancerous tissue and normal colorectal mucosa （2377.95 ± 865.80 vs 3216.58 ± 1149.42 and 3541.61 ± 1433.17 respectively, p 〈 0.01）. In addition, when p21^WAF1 mrNA expression was undectectable or at very low level （50% less than that in adjacent tissue and normal colorectal mucosa） in all tissues, the level of acetylated histone H3 in colorectal cancerous tissue was significantly lower than that in corresponding para-cancerous tissue and normal colorectal mucosa in five of seven （71.43%） cases. The transcriptional level of p21^WAF1 in colorectal carcinoma might not be associated with its biological behaviors.CONCLUSION： The down-regulation of p21^WAF1 transcription is involved in the tumorigenesis and development of colorectal carcinoma. The down-expression of p21^WAF1 mrNA in colorectal carcinoma might be associated with histone hypoacetylation in chromatin but not with biological behaviors.
