20% ) were assigned to 2 groups according to study intervention: group A ( n =72) receiving DFPP and group B ( n =41) as controls.Group A was subdivided into 2 groups:group A1 ( n =44) was treated by DFPP alone and group A2 ( n =28) was treated by DFPP plus Dac.The incidence rates of HAR,AR,adverse reaction,patie nt/kidney survival,kidney function were observed. All the patients obtained a fo llow-up ≥12 months. Results In 72 patients of group A ,the level of PRA decreased from (60.5?17.7)% to (19.3?11.2)%,with a mean of (41.2?16.9)% ( P 0.05),with 1 kidney-year survival of 94.4% in group A and 78.0 % in group B ( P 0.05);those of AR were 36.4% and 14.3%,respectively ( P 0.05).No difference in infection episodes an d adverse events between group A and PRA-negative recipients, the same as those between group A1 and A2. Conclusions DFPP can decrease the level of PRA significantly before transplantation by selectively eliminating the sensitive antibody,especially when combined with Dac,which can make sensiti zed recipients get the chance of transplanting and further reduce the incidence of AR.The patient/kidney survival rates of 1 year are satisfactory.Being well to lerated by the sensitized patients,treatment of DFPP combined with Dac is safe a nd effective.

Fast-track surgery (FTS) protocols was introduced to reduce surgical stress and facilitate postoperative recovery.It has been more than 20 years since it had been proposed and it was successfully used in many special subjects such as orthopedic,upper gastrointestinal,gynecological,thoracic,vascular,endocrine et al,but the implication in radical cystectomy was insufficient.The propose of this article was to summarize the implication of FTS in radical cystectomy and to promote the development of the protocol in radical cystectomy.

Objective To study the indication and means in dissection lymph nodes of the No.10 and No.11 without splenectomy in radical gastrectomy for gastric cancer. Methods According to the location, type of pathology, clinical and pathological classification, lymphatic drainage and spread of gastric carcinoma togather with the immunological function of spleen, selection of operative procedure without splenectomy should be considered, so the related literatures were reviewed. Results Retained spleen had been shown to improve 5 year survival of patients with gastric cancer of stage Ⅰ,Ⅱ and Ⅲ,splenectomy had been shown to improve 5 year survival of patients with gastric cancer of stage Ⅳ,whose carcinoma was infiltrating splenic and the lymph nodes of the No.10. The complications of different means of dissection of the lymph nodes made no difference.Conclusion Dissection of the lymph node without retained spleen or allogenic spleen transplantation is indicated for the patients with cancer of stage Ⅳ,whose spleen is invaded by the tumor.

Objective To observe the effect and safety of Ginkgo biloba extract (EGb) in patients with chronic allograft nephropathy (CAN),and to study the clinical protective mechanism of EGb.Method A prospective,non-randomized,controlled study was conducted on 103 cases of CAN from March 2013 to March 2015.All patients were divided into experimental group (group A,53 cases) and control group (group B,50 cases).The group A was treated with EGb.Patients were followed up for at least 6 months.Before and after treatment,the changes in renal hemodynamic parameters were observed.The biochemical parameters were also observed,including 24-h urinary protein,urinary albumin,serum creatinine (Scr),triglyceride (TG),total cholesterol (TC),estimated glomerular filtration rate (eGFR),platelet count (PLT),fibrinogen (FIB),D-dimer (DD),activated partial thromboplastin time (APTT).The clinical efficacy and safety were analyzed.Result (1) Therewere no significant differences in clinical and biochemical parameters between the two groups before treatment (P＞0.05).(2) After treatment,the systolic peak flow velocity (Vmax) of segmental artery and arcuate artery in the experimental group was significantly higher than in the control group,and the resistance index (RI) in the experimental group was significantly lower than that in the control group,P＜0.05.(3) In both two groups,the 24-h urinary protein,urinaryalbumin,TG,TC and Scr were decreased after treatment (P＜0.05),and eGFR was elevated (P＜0.05).Moreover,the changes in 24-h urinary protein and urinary albumin in the experimental group were more significant than the control group after treatment (P＜0.05).(3) PLT,FIB and DD in experimental group were significantly decreased after treatment,and APTT was increased significantly (P＜0.05).PLT,FIB,DD and APTT had significant change after treatment in the experimental group as compared with control group.(4) There were no significant differences in adverse reactions between two groups (x2 =0.047,P =0.828).Conclusion The therapy of EGb in patients with CAN could reduce urinary protein and improve hypercoagulable state,and had few adverse reaction with good security.

Objective To evaluate the value of the thumper cardiopulmonary resuscitator in the emergency cardiopulmonary resuscitation(CPR).Methods Fifty cardiac mspiratory sudden stop patients with thumper cardiopulmonary resuscitator from January 2004 to December 2007 were recruited into treatment group,and 80 cardiac respiratory sudden stop patients with barehanded CPR from May 2000 to December 2003 were recruited into control group.The SBP and blood oxygen saturation 5 to 10 minutes after the resuscitation was compared.The rate of restoration of spontaneous circulation(ROSC),hospitalization and the complication in the two groups was compared.Results The treatment group was better than the control group in improving the SBP and blood oxygen saturation(P＜0.05).The rates of ROSC and hospitalization in the treatment group were higher than those in the control group(44%,40%and 25%,21%).P＜0.05.The rate of complications had no significant difference between the two groups.Conclusions Thumper cardiopulmonary resuscitator Can surmount the factors of medical staff or patients.It can make the CPR more standard andmore effective.MeanwhileitCan raisethe SBP,strokevolume and blood supplv to the heart and brain,and then mcrease the successful rate of CPR.

Autologous red blood cells (RBC) labeled with fluorescence were immitted into microvessel of SD rat and observed under microscope. The movement of each individual labeled RBC was recorded by microscope video camera system. The recorded videotape is replayed to sample dark background fluorescent images through frame grabber. Sampled frame images were separated into odd and even field sequence images. Then these sequence images were analyzed to get the flow rate. The error between the actual flow velocity value and the flow velocity value of fluorescent globules in the chamber measured under the same system was below 7%. The upper limit was 9.6 mm/s. There are no obvious differences (P > 0.05). This system has been applied in the research of rat microcirculatory disturbance, and the temporal flow rate change in microvessel was obtained.

Objective To investigate the biological effect of anti-leukemic cells induced by eosinophilic granulocyte (EOS) in bone marrow of patients with chronic myelogenous leukemia (CML).Methods The BCR-ABL fusion gene as well as the expression of IL-12 and IL-17 mRNA were performed by RT-PCR.The serum concentrations of cytokine IL-12 and IL-17 were determined by enzyme-linked immuno sorbent assay (ELISA).Immunochemistry staining and cytochemistry staining were used to observe the peroxydase (POX) and human Leukocyte antigen (HLA)-DR expression of EOS in bone marrow.Immunofluorescence staining was used to observe mannose receptor (MR),IL-12,IL-17A and IL-17receptor A (IL-17RA) expression of EOS.The results between the CML patients and the healthy controls were compared.Results Serum levels of IL-12 and IL-17 were higher in the 60 CML patients [(196.33 ±21.79) ng/L and (36.55-±3.01) ng/L] than those in the controls [(96.60 ±4.92) ng/L and (23.74 ±1.36) ng/L].In the 32 patients with activated EOS,the levels of IL-12 and IL-17 were (273.12 ± 17.16)ng/L and (40.11 ± 6.13) ng/L,which were significantly higher than those in the non-activated EOS [(126.16 ± 14.27) ng/L and (28.14 ±5.29) ng/L] (P values ＜0.01).IL-12 and IL-17 mRNA were expressed in activated EOS,while BCR-ABL fusion gene was not found.The amounts of EOS were increased abnormally in the bone marrow and peripheral blood of the CML patients with POX positive staining in the cytoplasm and weakly positive HLA-DR staining.It was observed easily by a microscope that EOS could attack leukemic cells in bone marrow through adhesion,capture and phagocytosis.Activated EOS could express IL-12,IL-17A and MR,which was related with the serum levels of these cytokines.Conclusions Activated EOS in bone marrow of CML patients could express IL-12 and IL-17.Activated EOS could induce coup injury to leukemic cell by releasing POX and expressing IL-12 and IL-17.It can also capture or swallow target cells via the expression of MR on the membrane.EOS may play an important role in the anti-tumor immunologic function in bone marrow of CML patients.

Objective To investigate the effect of swifch from cyclosporine to FK506 on renal allograft outcome after initial acute rejection. Methods Clinical outcome of patients who experienced first acute rejection episode were retrospectively analyzed. After initial acute rejection, 23 patients were switched to FK506-based immunosuppression, and 63 patients continued CsA-based immunosuppression. Demographic data, lipid, serum creatinine, uric acid, incidence of recurrent acute rejection and graft survival were analyzed and compared. Results During one year after anti-rejection therapy, incidence of biopsy-proved recurrent rejection events was significantly lower with FK506 therapy (1/23, 4.35%) compared with CsA therapy (16/63, 25.40%)(P=0.033). 5-year graft survival rate of FK506-based immunosuppression group was higher than that of CsA-based immunosuppression group (100.0% vs 81.4%). Serum uric acid level of FK506-based immunosuppression group from 24 months to 36 months after initial rejection were significantly lower than that of CsA-based immunosuppression group [(265.5 ±147.9) μmol/L, (245.8±88.9) μmol/L vs (428.5±119.3) μmol/L, (441.2±125.3) μmol/L, P<0.01, respectively]. Conclusion Conversion to FK506 therapy can significantly reduce recurrent rejection episode, and decreasing serum uric acid level provides long-term benefits to graft survival.

Objective To evaluate the prophylactic efficacy of compound sulfamethoxazole (SMZco)combined with ganciclovir on severe pulmonary infection in the early stage of renal transplantation. Methods Between January 2005 and January 2006,two hundred and forty renal allograft patients in our hospital were enrolled in this study.All the patients were divided into two groups.Group A(n=84)received oral SMZco combined with intravenous ganciclovir.Group B(n=156)received intravenous ganciclovir only as control.According to the time of SMZco administration,group A was divided into two subgroups:group A1(within 2weeks after transplantation,n=43)and group A2(more than 2 weeks after transplantation,n=41).All the patients were followed up for 9 months.Incidence of pulmonary infection and effects on graft function by SMZco at different time point were investigated. Results The incidence of severe pulmonary infection and mortality of infection were significantly lower in group A than those in group B (2/84 vs 16/156,P=0.027;0/2 vs 2/16,P＜0.01).There were no significant differences between two groups in terms of age,gender,warm or cold ischemia,complement dependent cytotoxieity test results,incidence of urinary infection and Scr.The incidence of elevatedScr was significantly lower in group A2 than that in group A1(15/43 vs 2/41,P＜0.01),however,all the elevated Scr returned to basal level within 1 week after SMZco was discontinued.Conclusions Oral SMZco combined with ganciclovir administration after renal transplantation is effective on preventing severe pulmonary infection and thus improves graft and recipient survival.The administration of oral SMZco initiated more than 2 weeks after transplantation is better for graft function.
