Objective To investigate the changes and their significance of bcl-2 and c-myc in nordihydroguaiaretic acid (NDGA)-induced apoptosis of human malignant glioma cell line SHG-44. Methods The apoptosis of SHG-44 cells was observed with light and electron microscopy and TUNEL method. The expression of bcl-2 and c-myc gene was measured with immunohistochemistry, in situ hybridization and image analysis. Results ① The SHG-44 cell apoptosis was induced by NDGA at a concentration lower than 200 μmol/L in a time-dependent manner. ② The expressions of bcl-2 and c-myc gene in SHG-44 cells were decreased after the treatment of 100 μmol/L NDGA with the elapse of time, indicating a close association with cell apoptosis. ③ The expressions of bcl-2 and c-myc mRNA in SHG-44 cells were decreased after the treatment with 100μmol/L NDGA, which was apparently consistent with the immunohistochemical results. Conclusion The NDGA-induced apoptosis in human malignant glioma cells might be related with the down-regulated expressions of bcl-2 and c-myc gene. The exact mechanism needs further research.

Objective To evaluate the volume of left ventricle (LV) based on PET-CT in left-sided breast cancer patients treated with adjuvant radiotherapy. To assess the impact of dose and volume in interrelations for heart and cardiac sub-structures using dose-volume histograms. Methods From October 2008 to February 2009, 14 patients with post-operatively confirmed left-sided breast cancer were enrolled in this study. Patients were scanned using contrast enhanced CT for simulation and FDG PET-CT have been applied to display the structure of left ventricle in each patient before radiotherapy (RT). The LV has been delineated based on PET-CT. Other critical sub-structures, such as left anterior descending coronary artery (LAD) have been contoured in each patient. The six-field simple intensity modulated radiotherapy (slMRT)technique has been created in all patients. Results The mean volumes of left ventricle based on PET-CT (LV-PET) were 112. 931 cm3. The volume of LV receiving ≥50% prescription dose highly correlated with the volume of heart receiving ≥50% prescription dose (R = 0. 869, P = 0. 000). There was less correlation between the volume of LAD and the volume of heart receiving ≥ 50% prescription dose ( R = 0. 220, P =0. 440). Conclusions The left ventricle could be delineated efficiently based on imaging of PET-CT. The volume of LV receiving higher dose in RT has high correlation with the volume of heart using sIMRT technique. It may pave the way for further exploring radiation induced cardiac injury in patients with breast cancer.

Objective To determine the change of tumor bed volume during whole breast irradiation by repeated computed tomography scanning and to analyze the dosimetric impact of boost-planning on different CT images. Methods From July 2008 to Jan 2009, sixteen patients with early-stage breast cancer underwent breast conservative surgery (BCS) were enrolled in the study. All patients received whole breast irradiation and tumor bed boost, no adjuvant chemotherapy was given. Two additional CT scans were acquired in addition to the planning CT ( CT1 ), one in the course of radiotherapy ( CT2 ) and the other before the boost (CT3). Tumor beds were contoured in all CT images. Three-dimensional conformal radiotherapy planning for tumor bed boost was done on CT1 and CT3 respectively. Results The mean tumor bed volume on CT1, CT2 and CT3 were 49.5 cm3, 25.6 cm3 and 22. 2 cm3 ( F = 5. 63, P = 0. 007 ),respectively. Further analysis found statistically significant difference between CT1 and CT2 ( q = 0. 03, P =0. 010), CT1 and CT3 ( q = 0. 01, P = 0. 004), but not between CT2 and CT3 ( q = 1.00, P = 0. 333 ). The average reduction of tumor bed volume from CT1 to CT3 was 43.4%. A reduction of 20% or above was found in 88% of the patients ( n = 14), 50% or above in 38% of the patients (n = 6). In the boost-planning, the volume of the ipsilateral breast receiving 100% prescribed dose (V100%) on CT1 and CT3 was 183.5 cm3 and 144. 5 cm3, respectively ( t = 3.06, P = 0. 008 ). Conclusions Volume of tumor bed is dynamically reduced in the course of whole breast irradiation after BCS, with more important reduction in the early weeks after the beginning of irradiation. A second CT scan before tumor bed boost is warranted.
