Objective: To evaluate the efficacy and toxicity of rituximab combined with cyclophosphamide, pirarubicin, vincristine, and prednisone (R-CTOP regimen) for B cell non-Hodgkin's lymphoma and to analyze the influential factors for patient response.Methods: The clinical data of patients with CD20 antigen treated with R-CTOP regimen were reviewed and the influence of sex, age, clinical stage, pathological type, and level of LDH and IPI on patient response was analyzed.Results: A total of 33 patients were evaluated for objective response.The complete response (CR) rate was 51.5%, the par-ticel response (PR) rate was 33.3%, and the overall response rate was 84.8%.For the 23 de novo patients, the CR rate was 56.5 %, the PR rate was 34.8%, and the OR rate was 91.3%.While in the 10 recurrent patients, the CR rate was 40%, the PR rate was 30%, and the OR rate was 70%.Sex, clinical stage, pathological type, and the level of LDH and IPI were not significantly related to clinical response.While patient age was related to clinical response.None of the patients died of therapy-related side effects.The most frequent adverse event was myelosuppression (Ⅲ-Ⅳ decrease of leukocyte account-ed for 32.1%).Cardiotoxicity and alopecia were mostly grade Ⅰ to grade Ⅱ.Other side effects can be tolerated after symp-tomatic treatment.Conclusion: R-CTOP regimen is a highly effective and well-toleraed therapy and should be the first choice in the treatment for B cell non-Hodgkin's lymphoma (NHL), especially for senior patients.

Objective To evaluate the efficacy and safety of fludarabine and pirarubicin (FT) regimen in the treatment of refractory or relapsed indolent non-Hodgkin lymphoma (NHL). Methods A total of 40 patients with relapsed or refractory indolent NHL were treated with FT regimen, one cycle for 28 days, total 6 cycles. The data of indolent NHL patients treated with fludarabine, noventrene and dexamethasone (FND) regimen were collected as control. Results 40 patients were given 228 cycles chemotherapy, overall response rate was 62.5 %, median progression-free survival was more than 20 months and 2 years overall survival rate was 70.0 %. The main toxicities was leucopenia (80.0 %), but the incidence of WHO Ⅲ-Ⅳ leucopenia and pneumonia was less than that of in the control group, the rate were 12.5 % vs 29.0 % and 2.5 % vs 23.0 % respectively (P <0.05). Conclusion The efficacy of FT regimen was as good as FND regimen, but the incidence of leucopenia and pneumonia by Ⅲ-Ⅳ was lower in FT group than in FND group. So the FT regimen was an effective and safe second-line salvage regimen for relapsed or refractory indolent non-Hodgkin lymphoma.

Induced-current electrical impedance tomography (ICEIT) is a newly hot research field in electrical impedance tomography (EIT) because of its advantages of contactless exciting. A preliminary ICEIT system with 3 excitation coils has been accomplished. It includes the constant current source (CCS), power amplifiers, excitation coils,physical phantom, measurement-mode setting circuit, signal measuring block, DAC and digital I/O card. The CCS is accomplished with Direct Digital Synthesis (DDS) technique. Its frequency is 46.875 KHz. Its output current is divided into 16 steps from 0.16 mA to 2.56 mA which can be set by computer. The three driving coils have the same diameter of 50 cm, each coil's inductance is 193.5 microH. The power amplifier can provide 800 mA driving current (f = 46.875 KHz) to the coil under +/- 25 V power supplying. The signal from measurement electrodes is switched to measurement channel which includes IA, BP filter and synchronized demodulator, then the analog signal is converted to digital signal by a 12b A/D Card and the data is acquired by DMA mode. Our experiments show that a distinguish change of signal from the surface electrodes can be acquired by the experimental system when different objects are placed in the physical phantom. And 3 x 31 signals for preliminary imaging have been acquired.
