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.

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 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.

ObjectiveTo evaluate the reliability of the Cybex 6000 isokinetic dynamometer in measuring the shoulder extensor contracted concentrically and eccentrically.Methods15 male subjects with no previous shoulder injuries were studied. The extensor muscles groups of asymmetrical shoulder were tested at 60°/s, 120°/s, and 180°/s respectively. Variables studied included peak torque (PT), average power (AP) and total work (TW). The interclass correlation coefficient (ICC) was used to determine the reliability.ResultsHigh test-retest reliability, ICC ranging from 0.86 to 0.97, was demonstrated for all tests.ConclusionThe Cybex 6000 isokinetic dynamometer shows a good reliability in measuring the shoulder extensor isokinetic contracted concentrically and eccentrically.

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.

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 study the effects of CYP3A5 * 1 and CYP3A5 * 3 genotypes on tacrolimus dose requirement.Method We tested archival peripheral blood of 69 kidney recipients for CYP3A5 genotyping by polymerase chain reaction.The dose,blood concentrations and dose-normalized blood concentrations of tacrolimus were measured at 1st and 2nd month after the renal transplantation.Result There were 6 cases of CYP3A5 * 1/* 1 (8.7%),22 cases of CYP3A5 * 1/* 3 (31.9%),and 41 cases of CYP3A5 * 3/* 3 (59.4%).At 1st and 2nd month after the renal transplantation,the carriers of CYP3A5 * 1 genotype had a higher mean tacrolimus dose than CYP3A5 * 3/* 3 genotye (both P<0.000 1),and those of CYP3A5 * 1 genotype had lower mean tacrolimus concentrations than CYP3A5 * 3/* 3 genotye (P=0.020 8,and P =0.019 1 respectively).Meanwhile,the carriers of CYP3A5 * 1 genotype had lower dose-normalized blood concentrations of tacrolimus than CYP3A5 * 3/* 3 genotye (P<0.000 1) at 1st month after the renal transplantation,as well as at 2nd month after the renal transplantation (P =0.0191).Hepatic and renal function showed no significant effect on tacrolimus dose adjusted concentration at 1st and 2nd month after transplantation.Gender did not show a significant impact on tacrolimus dose.Conclusion CYP3A5 * 1 carriers needhigher tacrolimus dose than CYP3A5 * 3 homozygote to achieve the target blood concentration.CYP3A5 genotyping is a new approach for detecting tacrolimus dose requirement in kidney recipients.
