The fundamental imaging features of osteosarcoma were showed bone destruction, periosteal reaction, neoplastic bone and soft-tissue mass. Among 49 cases examined by radiography, osteoblastic pattern sarcoma was found in 19 cases, osteolytic pattern sarcoma was found in 13 cases and mixed pattern sarcoma was found in 17 cases. The detection rates of bone destruction, periosteal reaction, soft-tissue mass, neoplastic bone and Codman triangle by radiography were respectively 61.2%, 95.9%, 71.4%, 73.5%and 27.7%. All 10 cases with CT scan were showed bone destruction, soft - tissue mass and neoplastic bone. The detection rates of periosteal reaction,憇ieve sign挶 and Codman triangle with CT scan were respectively 90%, 90% and 11%. The tiny neoplastic bone and"sieve sign"were showed sensitively by CT, but Codman triangle was showed by radiography superior to CT.32 cases with MRI scan presented the normal marrow was replaced by the tumor, which was showed low to intermediate signal intensity on T1-weighted images and promiscuity signal intensity on T2-weighted images. 7 cases presented hemorrhage and 24 cases presented necrosis.

In order to isolate the active compounds in ethyl acetate fraction of Psoralea corylifolia L., activity-guided isolation was performed along with chromatographic techniques. Four active compounds were isolated from ethyl acetate fraction and identified by their NMR spectral data and physical-chemical properties. They are corylin and bavachin, which showed stimulating effect on osteoblastic proliferation and differentiation, isopsoralen and psoralen exhibited activity of promoting cell differentiation in some degree.

为了追踪分离补骨脂乙酸乙酯萃取物中的活性成分，本实验采用多种色谱分离技术，以活性测试为导向，结合波谱技术及理化数据，从补骨脂乙酸乙酯萃取物中分离并鉴定了4个活性化合物的化学结构，它们是具有促进细胞增殖和分化作用的补骨脂异黄酮和补骨脂二氢黄酮，对细胞分化有一定促进作用的异补骨脂素和补骨脂素。
