Allogeneic stem cell transplantation is the only treatment which may cure multiple myeloma (MM).The high transplantation related mortality (TRM) limits the wide clinical application of myeloablative allogeneic stem cell transplantation.Non-myeloablative allogeneic stem cell transplantation can reduce the TRM,but the risk of relapse and progress of the disease may get increased. Autononmyeloablative allogeneic stem cell tandem transplantation can reduce both the TRM and the relapse and progress of the disease. At present,there exist many new methods which may improve the effect of allogeneic stem cell transplantation for MM in clinical.

OBJECTIVETo explore the diagnostic value of the radiologic characteristics of osteoporotic Kummell's disease.
METHODSTotal 16 patients with pathologically confirmed osteoporotic Kummell's diseases were reviewed from May 2010 to May 2012, including 4 males and 12 females with the mean age of 73.4 years (ranged, 67 to 83 years old). Radiologic imagings of all patients, including X-ray, CT and MRI, were analyzed retrospectively.
RESULTSIntravertebral linear clefts could be seen on the AP and lateral X-ray films of vertebrae. Sagittal and axial CT scans demonstrated the vacuum cleft phenomenon with liquid and air was identified within the vertebral body. Sagittal MRI showed the callapsed vertebral segment and the area of fluid signal with clear and intact border within the vertebral body. The fluid signal was low on T1-weighted images and high on T2-weighted images and stir images, which was corresponding to an intravertebral vacuum cleft.
CONCLUSIONThe radiologic characteristics of Kurmmell's diseases can provide valuable evidences for the early diagnosis.

Objective To assess the level of radiation exposures of operators in three typical types of interventional fluoroscopic procedures.Methods Alderson Radiation Therapy (ART) phantom was used to stimulate the practices of diagnosis and therapy using TLDs for dose measurement.The radiation exposures of eye lens, neck, and breast were measured when the lead shielding of machine was on/off and the equivalent dose and effective dose to the eye lens were estimated.Results Radiation exposure of head was obviously reduced by 85% -90% when the lead shielding was on.The doses in different procedures were different.In cerebral angiography the dose equivalent of eye len was the highest in the three procedures.The annual effective dose for the operators was smaller in peripheral vascular interventions than that in cardiovascular interventional therapy and that in cerebral angiography.Conclusions The operators involved in intervention will receive an annual effective dose of less than 20 mSv as recommended by the ICRP under the protection conditions provided by the current study, except for eye lens.Attention should be paid to the protection of the eyes of operators.

Objective To study the radiation dose level and dose distribution of leakage and scattering radiation in a helical tomotherapy (TOMO) room,and to identify the dose distribution characteristic which is different from the conventional radiotherapy so as to provide scientific data for the radiation protection of TOMO.Methods A helical tomotherapy facility typed Tomotherapy Hi-Art was employed as the radiotherapy device.The air kerma from leakage radiation and scattering radiation distributed on the couch plane and in TOMO room were detected mainly by GR-200A TLDs of LiF(Mg,Cu,P),while 100 Gy were being accumulated under the condition of simulation radiation treatment.Then,the leakage radiation ratio and scattering-leakage radiation ratio (the ratio of site radiation dose to isocenter standard output dose) were calculated.Results The radiation level and dose distribution of leakage radiation and scattering radiation in the TOMO treatment room were in bilateral symmetry to the rotation isocenter and the treatment couch longitudinal axis,and the radiation level in front of the radiotherapy device was significantly higher than that of the rear of the TOMO equipment.In the plane of treatment couch,the maximum leakage radiation ratio at the position 100 cm away from the isocenter was only 1.3 × 10-4,and the mean value of the leakage radiation ratio at the position 300 cm away from the isocenter was lower than 2.0 × 10-5.The scattering radiation at 200-300 cm away from the isocenter was accounted for 25%-30% of the leakage radiation from the responding sites,and the indoor scattering radiation decreased faster than leakage radiation with the distance from the isocenter.Conclusions The radiation level of leakage and scattering in a TOMO room is significantly lower than that in a conventional radiotherapy room.

This study was conducted to evaluate the relationship between serum insulin levels and the production of insulin antibody (IA) in type 2 diabetes (T2DM).A total of 647 T2DM were included.Among them,20.9% patients were IA positive,who were elder and had a longer duration,lower BMI,a higher positive rate of glutamic acid decarboxylase antibody(GADAb) and higher serum insulin levels during an insulin secretion test.More patients were treated with insulin in IA positive group than in IA negative group (65.9% vs 41.0%,P =0.000).Fasting serum insulin level was associated with occurrence of IA in all patients (OR =1.02,P =0.001) and insulin treated patients (OR =1.033,P =0.002).The cut-off point of fasting serum insulin level for predicting IA positive was 17.87 mIU/L (sensitivity 55.1%,specificity 89.0%).Exogenous insulin use is associated with the presence of IA.Fasting serum insulin level can be used as a predictor for the production of IA in insulin-treated patients.

Objective To evaluate the influence of tissue factor pathway inhibitor 2(TFPI-2)gene on the proliferation and invasion of K562.Methods The expression vector pcDNA3.0/TFPI-2 was transfected into human leukemia line K562 cells(K562-T)by using liposome,then the mRNA and protein TFPI-2 were detected by real-time RT-PCR and western blot separately.The growth curve and the colony-forming unit assay were used to measure the ability of cells growth and transwell chamber model was employed to test the ability of cell invasion in vitro.Results Expression of mRNA and protein of TFPI-2 was detected in transfected cells.The growth rate and self-replication ability of K562-T cells were lower than those of the two control groups obviously.The number of K562-T cells to traverse a Matrigel-coated membrane was dramatically decreased compared with that of non-expressing cells.Conclusion The gene of TFPI-2 can inhibit the growth,proliferation and invasion of the K562 cells.
