Objective To study the relationship between the expression of vascular endothelial growth factor (VEGF) and invasion, metastasis of primary hepatocellular carcinoma (PHCC). Methods Paraffin-embedded specimens from 30 patients with PHCC undergoing radical resection were studied. Agiogenesis was assessed by the expression of VEGF and microvascular density (MVD) using LSAB immunohistochemical staining. Results (1) The level of VEGF and MVD in PHCC was higher than that in the paratumorous tissue (P<0.05). (2) The level of VEGF expression and MVD in PHCC with tumor metastasis or in nonencapsulated tumors were higher than that in PHCC without metastasis or in well encapsulated tumors (P<0.05). (3) There was no significant differance in the expression of VEGF and MVD between large PHCC (diameter >5cm) and small ones (diameter ≤5cm). (4) The expression of VEGF was positively correlated with MVD (P<0.01). Conclusions The expression of VEGF and MVD are highly correlated with invasion and metastasis in PHCC, may serve as a parameter for determining tumor metastasis and prognosis which may suggest a new idea to supervise and treat PHCC.

Objective To evaluate the accuracy of the patient positioning in prostate cancer therapy with the kilo-volt X-ray imaging system. Methods From June to August in 2014,14 patients with prostate cancer were treated by carbon ion beam with the Siemens proton and carbon ion equipment. X-ray orthogonal images was made twice by the imaging system before treatment. All the images were fused with the planning digitally reconstructed radiograph ones by automatic and manual method. We got positioning error data in six directions:lateral, longitudinal, vertical, isocentre, roll and pitch. The data were analyzed to study the situation. Results A total of 644 pairs of images from 14 patients were obtained during treatment. The average error in six directions is 0. 34 cm,0. 30 cm,0. 79 cm,0. 3°,1. 1° and 0. 5°.The patients′positioning error had no obvious change in all directions with fractions. There was no significant deviation between the two groups of images,either. But error in pitch and vertical direction is much larger. Conclusions The bony landmarks of the orthogonal filed images are clear. Photography lasts short time by the imaging system. DRR images are 3D and we can get images in six directions,but the development of soft tissue is weak. Positioning error we get cannot be match with the one of actual situation.

Background and purpose: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a new minimally invasive method in the dignosis for mediastinal lymph nodes. This study was to evaluate the diagnostic yield of EBUS-TBNA for mediastinal lymph nodes. Methods: Twenty patients with mediastinal lymph nodes found by CT underwent the dignosis by EBUS-TBNA form April 1st 2009 to July 16th 2009. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of EBUS-TBNA were evaluated. Results: Twenty patients with 37 lymph node groups were studied. Overall sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of EBUS-TBNA for diagnostic were 84.62%, 100%, 100%, 77.78% and 90.00%, respectively. The diagnostic accuracy for cancer was 100%. The operation time was 11.9min per group in average with no serious complication. The median length of hospital stay was 1 (range from 1 to 17 days) day after operation. There were significant differences in the average operation time between the first three patients and the others (36.25 min vs. 7.76 min; z=3.247, P=0.001). Conclusion: Endobronchial ultrasound-guided transbronchial needle aspiration proved to be a safe procedure with a high yield for the diagnosis of mediastinal lymph nodes.

Objective: To explore the anti-proliferation and apoptosis-inducing effects of decitabine combined with paclitaxel on paclitaxel-resistant MCF-7 cells. Methods:Cell counting kit-8 (CCK-8) assays were used to determine the proliferation inhibition of drugs at different concentrations in 24, 48 and 72h. The group was treated with decitabine, paclitaxel and the combination of the two drugs, respectively. The cell apoptosis rate was determined by flow cytometry after the treatment with the drugs at different concentra-tions in 48h. Results:The results of CCK-8 showed the combination group significantly inhibited the cell proliferation when compared with the single drug use group(P<0. 05), and the anti-proliferation value was in a dose-dependent manner in all groups. The apopto-sis values after the treatment with decitabine, paclitaxel and the combination in 48h was(20. 4 ± 1. 98)%,(21. 8 ± 3. 34)% and(70. 8 ± 8. 23)%,respectively. Conclusion:The proliferation inhibition and apoptosis induction are both increased significantly in the com-bination group. Synergistic effect of decitabine and paclitaxel is found in multidrug resistant breast cancer cell line MCF-7 in vitro.
