Objective: To investigate the application of conventional ultrasound and 16-slice CT examination in clinical diagnosis of hepatocellular carcinoma (HCC) and hepatic focal nodular hyperplasia. Methods: To choose 94 cases patients were receiving treatment in our hospital who were diagnosed as hepatic focal lesion through percutaneous biopsy of hepatocyte or histopathological examination of postoperation, and then take conventional ultrasound and 16-slice CT, respectively, to detect them. To compare and analyze the two methods in series of indicator, such as accuracy, the number of lesion size and the imageology character. Results: Conventional ultrasound diagnosis of benign tumor lesions was consistent with spiral CT results, and the difference was not statistical significance (x2=0.5556, P>0.05). The accuracy of spiral CT for hepatic carcinoma was higher than that of conventional ultrasound, and the difference was significant (x2=8.1987, P<0.05). The consistent rate of the spiral CT group with real result for micro-miniature carcinoma (the diameter less than 1 cm) was higher than that of conventional ultrasound group, and their difference was significant (x2=14.4028, P<0.05). The disappear and persist time of hepatic carcinoma patients were longer than that of non-hepatic carcinoma patients, and the difference between them was significant (t=9.7531, P<0.05). Conclusion: It is higher accuracy that 16-spiral CT can diagnose malignancy lesions in earlier stage.

BACKGROUND:Studies have funded that reduced Wnt/β-catenin signaling is involved in the onset and/or progression of bone erosion in rheumatoid arthritis. It can lead to potential new treatment approaches of bone erosion by enhancing Wnt/β-catenin signaling pathway. R-spondin 1 may act as a Wnt agonist, but there is no study in human osteoblasts. OBJECTIVE:To verify the effect of R-spondin 1 on promoting differentiation and maturation of human osteoblasts by inhibiting DKK1. METHODS:S40-transfected human osteoblast lines, hFOB1.19, were treated with R-spondin 1, Wnt-3a and DKK1 to detecting the proliferation, alkaline phoshpatase activity and osteoprotegerin concentration. RESULTS AND CONCLUSION:R-spondin 1 had no effects on hFOB1.19 cel s. Wnt-3a upregulated the activity of alkaline phoshpatase, which could be enhanced by addition of R-spondin 1. R-spondin 1 could reduce the DKK1-mediated inhibition of alkaline phoshpatase activity in hFOB1.19 cel s. R-spondin 1 increased the concentration of osteoprotegerin, and moreover, the promotion of osteoprotegerin by R-spondin 1 alone was stronger than the inhibition by DKK1. These findings suggest that R-spondin 1 can inhibit DKK1 by Wnt/β-catenin signal pathway to promote the differential and maturation of human osteoblasts to excrete osteoprotegerin.
