ABSTRACT
Objective To investigate the safety and effectiveness of radioactive 125I seed implantation in treating recurrent cervical lymphatic metastases after radiotherapy. Methods During the period from Aug. 2011 to July 2012, 17 patients with recurrent cervical lymphatic metastases who had received radiotherapy before were admitted to authors’ hospital. The clinical data were retrospectively analyzed. A total of 23 metastatic lymph nodes were detected in the 17 patients. Brachytherapy treatment planning system (TPS) was used to formulate the number, activity and distribution of radioactive 125I seeds. The radioactive activity was 0.3 - 0.8 mCi (1.30 × 107- 2.96 × 107 Bq), and the matched peripheral dose (MPD) was 60 - 120 Gy. Guided by ultrasound and CT radioactive 125I seeds were implanted under local anesthesia. CT scanning was performed within 24 hours after the procedure. Postoperative D90 was (81.4 ± 2.1) Gy. CT examination was employed every two months to determine the tumor size and to record the complications. Results All patients were followed up for 6 months. The 6-month local control rate was 65.2%. The control rates (CR+PR) for4 cm (n=13) lymph nodes were 90%and 46%respectively, the difference between the two was statistically significant (P = 0.038). No significant difference existed between the control rate (CR + PR) and the un-control rate (SD + PD) for each lymph node group at cervical Ⅰ, Ⅱ, Ⅲ and Ⅴ grade Ⅱ was seen in 8 cases and grade Ⅰ in 7 cases. No severe complications occurred. Conclusion For the treatment of recurrent cervical lymphatic metastases after radiotherapy, radioactive 125I seed implantation is effective and mini-invasive with fewer complications. This technique is more suitable for < 4 cm solitary metastatic lymph node with clear border.

ABSTRACT
Objective To investigate the radiosensitizing effect of tetrandrine in human esophageal carcinoma cells (TE1) in vitro and its related mechanisms. Methods The cell proliferation was assessed by MTT assay. Colony formation was used to analyze radiosensitivity enhancement by tetrandrine in TE1cells. Western blotting was preformed to measure the cyclin B1 protein levels. Results Tetrandrine inhibited cell growth in a concentration and time depedant manner. The inhibition of proliferation was observed when cells were treated by 1.0, 5.0 and 10. 0 μg/ml tetrandrine for 24 h after irradiation ( P ＜0. 05;F= 3.09, 10.43 and 24. 00, respectively). The inhibition was more significant when cell were treated by 0. 1, 1.0, 5.0 and 10. 0 μg/ml tetrandrine for 48 h than 24 hours after irradiation (F =4. 12,12. 77, 44. 28, and 48.53 respectively ,all P ＜ 0. 01 ). The D0, Dq and SF2 decreased with the increase of the tetrandrine concentration. The maximal sensitizing enhancement ratio was 1.60 with 0. 5 μg/ml tetrandrine. Tetrandrine upregulated the expression of cyclin B1 and removed G2 / M arrest . Conclusions Tetrandrine can enhance radiosensitivity of TE1 cells. This effect may be associated with the increase of cyclin B1 expression to remove G2/M arrest.
