Methods The patients of AI-IFJ group were irradiated to large-field target volume by a daily fraction of 2Gy, and small-field target volume by a daily fraction of 1Gy with more than 6h interval. The total dose of large-field target volume was SOGy/25Fx/SW and of small-field target volume was 7SGy/SOFx/5W. The patients in CFI group were irradiated by a daily fraction of 2Gy to the total dose of 66Gy/33Fx/6. 6W. After 3 months of radiotherapy, the tumor response rates of complete recovery (CR), partial recovery (PR), and no change (NC) and 1- and 2- year survival rate in the two groups were observed. Results The tumor response rates of CR,PR,NC in AHFI group and CFI group were 22.9%(8/35), 60.0%(21/35), 17.1%(6/35) and 11.4% (4/35), 51.4% (18/35), 37.2% (13/35) respectively (P>0. 05). All patients were followed up 2 years or more. The 1- and 2- year survival rates in AHFI group and CFI group were 62.9% (22/35), 31 .4% (11/35) and 42.9% (15/35) , 17.1% (6/35) respectively (P< 0.05). The incidences of esophagitis and pneumonitis in AHFI group and CFI group were 34.3% (12/35), 22. 9% (8/35) and 40.0% (14/35), 17.1% (6/35)(P>0. 05). Conclusion In comparison with CFI, AHFI may increase 1- and 2- year sur-vival rate after treatment of local advanced non-small cell lung cancer, while the radio-reactions, either early or late, did not increase significantly.展开更多

Main points Tanzhong (CV 17), Quchi (LI 11) and Jiaji (EX-B 2) were punctured, supplemented with other acupoints according to the concrete symptoms and signs and TDP irradiation for 30 min. For example, in the treatment of mastitis patients with high fever, bilateral Hegu (LI 4) and Taichong (LR 3) were punctured in combination with pricking blood and cupping methods. After 1-10 sessions of treatment (once daily), all the 600 cases were effective, with 510 cases (85%) being cured, 83 cases (13.8%) remarkably effective, and with 7 cases (1.2%) effective.展开更多

The transfection of p53 gene into U251 cells was confirmed by RT PCR. MTT showed that p53 gene alone induced strong inhibitory effect on the growth of U251 cells （inhibition rate （IR）： （79.60±5.69）%）, The killing effect of irradiation alone on U251 cells was not strong （IR： （17. 06±4.35）%, （17.39±1.67）%, （18.73±4.68）%） and increased with the irradiation doses （3, 6, 9 Gy）. When combined treatment of wild-type p53 gene transfection and irradiation was used, the effect was significantly increased （IR：（80.60±5.35）%, （90.30＋1.67） %, （91.30±2.01） %）. Theapoptosis rate of U251 cells induced by p53 gene transfectionwas 17.38 %. The rate induced by irradiation increased （4. 61%, 4. 84%, 5. 40 %） with the irradiation doses （3, 6, 9 Gy）. Theapoptosis rate was also significantly increased （17.80%, 20.03%, 22.34%） after combined treatment of p53 and irradiation with different doses （3, 6, 9 Gy）. It is concluded that wildtype p53 gene and irradiation could result in synergistic inhibitory effect on the growth of human glioma cells.展开更多
