Tumor 2010;(2):138-142
Objective:To investigate the expressions and their clinical significance of vascular endothelial growth factor (VEGF) and extracellular matrix (ECM) components in non-small cell lung cancer (NSCLC). Methods:Expressions of VEGF and ECM components (fibronectin, FN and collagen Ⅳ, cⅣ) in 50 cases of NSCLC tissues and 20 cases of normal lung tissues were detected by immunohistological analysis. Their relationship with clinical features of NSCLC and the correlation of expression of VEGF and Fn and cⅣ were analyzed.Results:The positive expression rates of VEGF, Fn, and cⅣ were 96%, 78%, and 50% in NSCLC tissues. The expressions of VEGF and Fn were significantly higher than those in normal lung tissues (P<0.05). The expression of Fn and over-expression of VEGF were associated with lymph node metastasis (r=1.00, P<0.001). The survival rate of patients with over-expression of VEGF was greatly lower than that with weak expression of VEGF (P=0.022). The survival rate of Fn-negative patients was markedly higher than that of Fn-positive patients (P=0.046). Conclusion:VEGF and ECM component Fn were highly expressed in NSCLC, which correlated with lymph node metastasis and survival rate. Expression of ECM and VEGF had positive correlations, suggesting that ECM might be one of the anti-angiogenesis targets for tumor therapy.

OBJECTIVETo compare the differences between computer aided identification and ultra-thin layer slicing in measuring the lesions of femoral head necrosis,and to confirm the accuracy and practicability of computer aided method.
METHODSFrom June 2012 to December 2013, the X-ray and MRI of 24 patients (24 hips on unilateral) were reviewed, who had avascular necrosis of the femoral head (ANFA) at late stage (stage III and IV) according to the ARCO international staging system. There were 15 males and 9 females, with an average age of (65.1 ± 8.8) years old, ranged 33 to 74 years old. Based on the software system with seeds point identification, the ragional adaptive search method with computer aid was used to calculate the volume of necrotic lesion in femoral on MRI. Then the pathological slices of those intraoperative femoral heads were made to measure the gross volume of necrotic lesion in femoral head,and the values were compared with the data in the computer.
RESULTSFor 24 hips, by the calculation of computer, the necrotic volume was (20.00 ± 3.04) cm (ranged, 18.72 to 21.29 cm³). Under the pathological section, the necrotic volume of the femoral head was (19.89 ± 3.17) cm³ (ranged, 18.55 to 21.23 cm³). In computer and pathology two kinds of measurement, the two entire femoral head volume had no significant difference using these two measurements (t = -1.227, P = 0.232).
CONCLUSIONComputer aided identification for necrotic area of femoral head adaptive can demonstrate the morphology of femoral head necrosis accurately and reliably, which will help surgeon better understand the morphology and orientation in femoral head.

OBJECTIVETo observe effects of serum Bushen Huoxue prescription(Chinese characters) on classic Wnt/β-catenin signaling pathways of osteoblasts, and explore mechanism of Bushen Huoxue prescription (Chinese characters) for preventing osteoporosis.
METHODSTwenty health female rats were randomly divided into two groups, including Bushen Huoxue (Chinese characters) group and saline group,10 in each group. Bushen Huoxue (Chinese characters) group and Saline group were gavaged Bushen Huoxue and saline every day for 1 week. Bushenhuoxue containing serum and saline containing serum were got according to methods of serum preparation of drug-containing. The osteoblasts was cultured with neonatal rat skull according to Enzyme Consumer Law, and was identified by Wright-Giemsa staining (R-J) and alkaline phosphatase staining (ALP). The third generation of osteoblasts was divided into three groups, including saline group, normal group,Bushen Huoxue (Chinese characters) group. Each group were added to 15% appropriate medium. ALP activity of osteoblasts and osteoblasts proliferation rate were tested, mineralized nodules were observed, the expression of β-catenin, Runx2, Osx mRNA of osteoblasts were tested by RT-PCR.
RESULTSThere was blue granules in cytoplasm, cell nucleus was flint with 1 to 3 nucleoli showed by R-J staining, morphology of osteoblasts were cultured. ALP staining showed cytoplasm with purple granules, the results showed that the cultured cell was osteoblasts. The content of ALP in Bushen Huoxue (Chinese characters)group was (6.272±0.131) ,appreciation rate was (0.81? 0.172), and could significantly improve differentiation and proliferation activity of osteoblasts compared with Saline group (P< 0.01). There were four different size orange nodules, the Maximun nodule was 1.0 x 1.0 cm in Bushen Huoxue (Chinese characters) group after Alizarin red staining, the results showed Bushen Huoxue (Chinese characters)group could obviously improve mineralization of osteoblasts. The expression of mRNA of β-catenin, Runx2 and Osx in Bushen Huoxue (Chinese characters)group were (1.782±0.944), (1.935±0.994) and (1.610±0.811) by RT-PCR,it was significantly increased compared with saline group (P<0.01), but there was no difference between Bushen Huoxue (Chinese characters)group and normal group (P>0.05).
CONCLUSIONBushen Huoxue (Chinese characters)group could obviously promote differentiation, proliferation and mineralization of osteoblasts through activation of Wnt, β-catenin signaling pathway. It suggested that the mechanism of action of Bushen Huoxue (O'f f Il.t)particle clould prevent osteoporosis through the activation of Wnt, β-catenin signaling pathway.
