Objective To summarize the modified clinical technique and experience of simultaneous kidney-pancreatic transplantation (SKPT) with enteric drainage(ED). Methods Two patients with insulin-dependent diabetes mellitus and end-stage renal disease underwent SKPT with enteric drainage of exocrine secretions.The patients were treated with quadruple therapy including antithymocyte globulin (ATG) induction therapy,prednisone,FK506,and Mycophenolate-Mofetil(MMF), as maintenance immunosuppression. Results The two patients became insulin-independent after treated by small dose insulin for 5～10 days and Scr,BUN became normal 3～5 days after the operation.Until now all the grafts of the patients functioned well. Conclusions ED-SKPT is more effective than simultaneous kidney-pancreatic transplantation with bladder drainage (BD-SKPT).ED-SKPT is an effective method for treating type Ⅰdiabetes mellitus with uremia.Finer allograft and nicer HLA-typing can decrease complications.

Objective To study the diagnosis and management of renal artery stenosis in kidney transplants. Methods 8 cases of transplant renal artery stenosis (TRAS) were reviewed and studied . Results Color-flow Doppler has been helpful in the diagnoses for 5 of the 8 cases with a specificity of 78% and a positive predictive value of 62.5%. 7 patients underwent PTRA and have been cured of the renal stenosis in a short term. On follow up for 3～12 months, the creatinine was 186.2～121.3 ?mol/L; 1 patient underwent nephrectomy. Conclusions TRAS should be considered when ever there is hypertension of unknown cause, a sudden reduce of urine volume and on increase of creatinine after kidney transplantation. Color-flow Doppler is indicated for the screening of TRAS whereas PTRA is the procedure of first choice for the management.

0.05). In group B,the serum creatinine levels of cases treated with ulinastatin at 1,3,7,10 and 14 days after renal transplantation were (372.6? 128.1 ),(278.4?38.9),(145.9? 47.2 ),(133.2?39.8),(128.0?30.6)?mol/L,respectively;the values of controls were (496.3?125.6),(364.7?60.2),(196.2?36.8),(161.4?41.5),(149.8? 33.5 )?mol/L,respectively ( P

Objective To explore the preliminary experience of combined liver-kidney transplantation.Methods Twelve patients were subjected to combined liver-kidney transplantation. The orthotopic liver transplantation was preceded with the classic fashion in 8 patients and the piggyback fashion in 4 patients. The pump-driven veuovenoas bypass technique was not used. And then the kidney transplantation was performed under stable homodynamic circumstance. The renal graft was implanted to the right iliac fossa routinely. The renal vein was anastomosed to the external iliac rein end-to-side, and the renal artery to the external iliac artery end-to-side or the hypogastric artery end-to-end. After operation, anti-CD25 monoclonal antibody or antithymocyte globulin (ATG), tacrolimus (FK506), mycophenolate mofetil and prednisone were used to prevent the allograft rejection.Results The survival rate of the 12 cases receiving combined liver-kidney transplantation was 100 %, and the graft function was restored well postoperation. An acute rejection episode of liver occurred in one patient. The FK506 toxicity occurred in one patient. The hemorrhage of digestive tract occurred in one recipient and the hemorrhage of peritoneal cavity in one patient. The pneumonia occurred in one case and the peritoneal infection in one patient. No patient experienced any episode of acute rejection of renal allograft.Conclusions The combined liver-kidney transplantation is the ideal option of patients with end-stage liver disease with chronic renal failure.

ObjectiveTo explore the diagnostic and differential diagnostic points in a patient with rheumatoid arthritis (RA) complicated with fever and pulmonary diseases. MethodsFull clinical analysis was performed for a 55-year old patient with arthritis, fever, and wheeze. ResultsThe clinical pictures of the patient were consistent with those of RA. Computed tomography(CT) revealed interstitial lung diseases and intrapulmonary cavities. Antifungal agents were given experimentally, and the intrapulmonary cavities disappeared finally, thus the patient was diagnosed as RA, concurrently complicated with interstitial lung disease and pulmonary fungal infection. ConclusionThe possibility of pulmonary fungal infection should be considered in RA patients who presented with fever and intrapulmonary cavities.

Objective To study corrective method for displacement in the procedure of electronic portal imaging device (EPID)-based intensity-modulated radiotherapy dose valuation by studying the relative mechanical displacement of different vendor EPID (aS1000,Varian; aS500,Varian; iViewGT,Elekta).Methods A 5 cm × 5 cm field was set up to acquire portal images for three kinds of EPID,then a in house software was used to analysis the portal images.The relative displacement was acquired via analyzing a series of comparation between center positions of gantry angle ranging from 0° to 360° and gantry angle at 0°.Results In the lateral direction,the maximum relative displacement of EPID with aS1000,S500 and iViewGT were (-0.23 ±0.17) mm,(2.94±0.17) mm and (0.35 ±0.09) mm,respectively.In the longitude direction,the displacements were (-4.16 ± 0.20) mm,(-4.15 ± 0.25) mm and (-1.66 ±0.11) mm,respectively.As to longitude direction,the displacements could be well fitted with the usage of quadruplicate empiric function.Conclusions There is a significant difference at the aspect of relative displacement between different vendors EPID at different gantry angles.And the displacement in the longitude direction is obviously larger than in the lateral direction.The relative displacement should be corrected when applying EPID to the intensity-modulated radiotherapy dose verification at different gantry angles.

Objective To investigate of the accuracy and feasibility of independent check for intensity-modulated radiotherapy (IMRT).Methods Inputing the linear accelerator Varian 600C/D physical data to IMsure ( a independent checking software) and constructing a calculation model.Use of IMsure to calculate the point dose and fluence of 25 cases IMRT treatment plans which have been calculated by Eclipse treatment planning system (TPS),and do a actual measurement of these plans by Matrixx at the same time.IMsure,TPS calculation results and measurement results of Matrixx were compared.Results Select Matrixx's center probe as a reference point,to TPS calculated results as the standard,then the average difference of the IMsure calculation and Matrixx measurement were ( -0.13 + 1.24)％ (t =0.20,P =0.840 ) and ( - 0.18 ± 1.45 ) ％ ( t =0.86,P =0.400 ),respectively.Compared IMsure with 3 mm/3 ％and 2 mm/2％ standard respectively,the average γ rate of TPS were (98.7 ±2.8)％ and (94.9 ±7.2)％ ;compared matrixx measurement results,the average γ rate of TPS were ( 99.0 + 2.0 ) ％ and ( 93.2 ±6.9) ％.The results show that the difference of the point dose and the γ rate of dose distribution by Matrixx measurement and IMsure calculation was no statistically significant difference ( t =1.54,P =0.126 ).Conclusions Independent checking software can be used in the treatment planning system to acceptance and initial clinical tests.In routine,a independent checking software as IMsure may do a pre-verificaton of IMRT treatment plan,or even partially replace of the actual measurement if the adequate conventional quality assurance do well,thus reducing the daily measurements.

Objective To study the In vitro expansion of human CD8+ CD28- suppressor T cells and their immunological regulatory effect.Methods Human CD8 + CD28- suppressor T cells were expanded in vitro driven by the combination of cytokines and allogeneic antigen presenting cells (APCs).Flow cytometry was used to assess the development of CD28- subpopulation.Expanded CD8+ CD28- T cells were isolated by immunomagnetic microspheres and then added as third part modulators into mixed lymphocyte culture to assess their immunological regulatory characteristics.Results The combination of cytokines included IL-2,IL-7 and IL-15 and allogeneic APCs could increase the portion of CD8 + CD28- T cell subtype,and expansion fold of CD8+ CD28- T cell subtype was significantly increased as compared with others (P＜0.05).Expanded CD8+ CD28- T cells could suppress the proliferation of CD4+ T cells stimulated by allogeneic APCs.Moreover,this suppression had antigen specificity.Conclusion Human CD8 + CD28- suppressor T cells can be in vitro expanded in large amounts driven by the combination of cytokines and allogeneic APCs.Expanded CD8 + CD28- T cells in this study have antigen specific regulatory characteristics.

Objective To evaluate whether serum cystatin C (SCys C) could be used as an ideal index to assess renal function of renal transplant recipients during posttransplant follow-up.Methods Seventy patients who were followed up for at least 6 months after renal transplantation in our centre were recruited in the study. SCys C and serum creatinine (SCr) were determined during the follow-up period, and glomerular filtration rate (GFR) was measured using an isotope Tc99m DTPA.The correlation between SCys C, SCr and GFR was analyzed. The performance of SCys C and SCr in diagnosing the mild impairment of renal allgraft function (GFR ＜ 1 ml/s) was evaluated using ROC curve. Results Both SCys C and SCr had a linear negative correlation with GFR (r = -0. 82 and -0. 66 respectively, P＜0. 01 ). The sensitivity, specificity and positive predictive values (PPV) of SCys C for diagnosing the mild impairment of renal allgraft function were higher than those of SCr,but the AUC of SCys C did not differ from that of SCr significantly (0. 935 vs. 0. 877, P＞0. 05).Conclusion SCys C could be used an ideal index to evaluate the allograft renal function for its better correlation with actual GFR.
