Objective To summarize our operational experience in using unusual renal allografts.Methods The plastic operations of 326 unusual renal allografts were retrospectively and the renal transplant outcome was compared with 542 normal renal allografts an the same time. Results All the 326 unusual renal allografts were utilized. There was no significant difference between unusual renal allografts and usual ones in average serum creatinine level, acute tubular necrosis (ATN) and the survival rate of renal allgraft after 1 year. There was no complications related to plastic operation during or after kidney transplantation.Conclusions By making good use of various kinds of plastic operation, abnormal or injuried renal allografts can also be used safely without affecting the outcome after renal transplantation.

Peripheral T-cell lymphoma (PTCL) is a relatively common subtype of non-Hodgkin lymphoma in China. PTCL is clinically highly aggressive, and it progresses rapidly. The current treatment methods are ineffective and the overall prognosis is poor. The 62nd American Society of Hematology Annual Meeting reported on the progress of PTCL molecular targeted therapy and immunotherapy, including programmed death receptor 1/programmed death receptor ligand 1 antibodies, JAK inhibitors, brentuximab vedotin, etc. These novel drugs bring a better prospect for patients.

BACKGROUND: To avoid acute rejection,it is necessary to use imunosuppressive drug regimen for long term to control immune state.However,imunosuppressive drug regimen of allogenic organ transplantation increases infection incidence of recipients,and induction of allograft immunological tolerance might be an ideal method for solving these problems.The long-term immunologic tolerance has been able to be induced in the experimental rodent models.Among these protocols,donor bone marrow cell (DBMC) infusion exerts an important role in the induction of allograft immunological tolerance.OBJECTIVE: To investigate effects of combination of cyclosporine A (CsA) with DBMC infusion on heterotopic rat cardiac allograft survival time.DESIDN: A randomized controlled animal experiment.SETTING: Renal Disease Center,First Affiliated Hospital of Zhejing University School of Medicine.MATERIALS: This study was performed at the Laboratory Animal Center,Zhejiang University School of Medicine between March 2002 and December 2005.Inbred male Lewis rats (n=40,serving as donors) and male BN rats (n=60,serving as recipients) of SPF grade were used in this study.The protocol was approved by the Hospital's Ethic's Committee.METHODS: Forty rats prepared for heterotopic rat cardiac allograft were randomly divided into 4 groups,with 10 rats in each: control group,in which,rats received no treatment,CsA group,in which,rats received CsA infusion for 7 days successively; CsA +DBMC group,in which,rats received DBMCs during and 6 days after the surgery and additional 7 successive days of CsA infusion,and a DBMC group,in which,rats received DBMCs infusion during and 6 days after the surgery.In addition,BN rats that received beterotopic rat cardiac allograft served BN controls.The survival time of heteroropic rat cardiac allograft was investigated.Serum interleukin-2 level and tumor necrosis factor-α mRNA expression level in the transplanted cardiac allograft were measured. The percentage of antigen presenting cells (APC) from donor,CD3+CD25+ cells,CD4+CD25+ cells,CD86+ cells,and the ratio for CD4+CD45RC+ and CD4+CD45RC- in the recipient peripheral blood karyocytes were measured by flow cytometry 6,12 and 18 days after surgery.MAIN OUTCOME MEASURES: The survival time of beteruropic rat cardiac allograft,serum interleukin-2 (IL-2)level,tumor necrosis factor- α (TNF- α ) rnRNA expression level, rejection grading,the percentage of DBMCs in the recipient peripheral blood karyocytes,CD3+CD25+ cells,and CD4+CD25+ cells,as well as CD86 expression,and the ratio for CD4+CD45RC+ and CD4+CD45RC.RESULTS: Forty Lewis male rats and sixty male BN rats were all included in the final analysis. The heterotopic rat cardiac allograft survival time was longer in the CsA +DBMC group than in the control group and DBMC group (P ＜ 0.05). Serum IL-2 level and TNF- α mRNA expression were respectively lower in the CsA +DBMC group than in the control group and DBMC group ( P ＜ 0.05).The rejection was milder in the CsA +DBMC group than in the remaining 3 transplantation groups.In the CsA +DBMC group,CD 86 expression in the recipient peripheral blood karyocytes was markedly inhibited,and 6 and 12 days after surgery,the ratio for CD4+CD45RC+ and CD4+CD45RC- and the percentage of CD3+CD25+ were respectively lower compared to control group and DBMC group.DBMCs in the recipient peripheral blood karyocytes were more in rats that received DBMC infusion compared to rats that received no BDMC infusion.CONCLUSION: Short-term CsA treatment combined with DBMC infusion can lower acute rejection of heterotopic rat cardiac allograft and prolongssurvival time of cardiac allograft.

Objective To elucidate the clinical features of nutcracker syndrome complicated with IgA nephropathy (IgAN) and to increase its level of diagnosis and treatment. Methods Clinical data of 14 cases of nutcracker syndrome complicated with IgA nephropathy (patient group) and 36 cases of nutcracker syndrome (control group) were analyzed retrospectively. Nutcracker syndrome was diagnosed by ultrasonography and magnetic resonance angiography (MRA) and IgAN by renal biopsy. Differences of clinical data and images in two groups were analyzed. Results Gender, age and blood pressure of two groups were not significantly different. Higher Scr level [(81.2±21.3) μmol/L vs (61.2±11.8) μmol/L, P<0.01], more severe proteinuria [(1.1 ± 0.6) g/d vs (0.3±0.2) g/d, P<0.01] and hematuria (2.3±0.9 vs 1.5±1.3, P<0.05) in patient group were found. Differences of ultrasonography and MRA in two groups were not significant. Conclusion Renal biopsy should be considered in cases of nutcracker syndrome with persistence of proteinuria, hematuria or abnormal morphology of urinary red blood cell.

OBJECTIVE:To evaluate the effectiveness and safety of inhaled furosemide in the adjuvant treatment of bronchial asthma systematically,and to provide evidenced-base reference for clinical treatment. METHODS:Retrieved from PubMed,Co-chrane library,CJFD,Wanfang database and VIP,randomized controlled trials(RCTs)about routine treatment+inhaled furosemide (trial group)vs. routine treatment(control group)in the treatment of bronchial asthma were collected. After quality evaluation and data extraction according to Cochrane systematic evaluation method 5.1.0,Meta-analysis was performed with Rev Man 5.3 soft-ware. RESULTS:A total of 13 RCTs were included,involving 708 patients. The results of Meta-analysis showed that:obvious ef-fective rate [RR=1.53,95%CI(1.28,1.84),P<0.001],total effective rate [RR=1.34,95%CI(1.23,1.45),P<0.001],the inci-dence of laryngeal discomfort [RR=10.79,95%CI(1.47,78.99),P=0.02] and gastrointestinal adverse reaction [RR=10.80,95%CI (1.43,81.53),P=0.02] in trial group were all significantly higher than control group,with statistical significance. There was no sta-tistical significance in the incidence of dry mount [RR=3.71,95%CI(0.81,16.86),P=0.09] and electrolyte disorder [RR=2.38, 95%CI(0.10,56.53),P=0.59] between 2 groups. CONCLUSIONS:Based on conventional treatment,the inhaled furosemide has good therapeutic efficacy and safety for bronchial asthma,and the laryngeal discomfort and gastrointestinal reaction should be strengthened.

Objective To observe and compare the effects of extracorporeal shock wave therapy(ESWT) and that of joint mobilization technique on periarthritis of shoulder. Methods Eighty-two patients were divided into two groups randomly, a treatment group (n=42) treated with extracorporeal shock wave therapy, and a control group (n=40) treated with joint mobilization technique. All the patients were evaluated with Visual Analogue Scale (VAS) and Constant-Murley Scale(C-M scale) before and half a month after the treatment. Results After treatment the results obtained with the use of VAS Scale and C-M Scale (only ADL and ROM) were significantly different in two groups when compared with those before the treatment (P

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 explore the effect of acute humoral rejection on kidney graft survival.Methods 1098 patients received cadaveric renal transplant from January 2002 to December 2008 in our center. All patients were given triple immunosuppressants including tacrolimus or cyclosporine.According to patients who experienced biopsy-proved humoral rejection and cellular rejection within one year post-transplant, there were 53 cases in humoral rejection group, 109 in cellular rejection group (including 63 patients with borderline change), and 936 in normal group. Patients who experienced acute rejection received mythyl-prednisolone pulse, or received anti-CD3 antibody/plasma exchange/globulin. Clinical characteristics before operation including sex, age, HLA mismatch, panel reactive antibody, cold/warm ischemic time, graft loss rate and graft survival were compared among three groups. The effect of completely reversed cellular rejection and humoral rejection on graft survival was analyzed. Results There was no significant difference in sex, age and cold ischemic time among three groups, but there was significant difference in warm ischemic time, level of PRA and HLA mismatch between cellular rejection group or humor rejection group and normal group (P＜0. 05). During a follow-up period, the incidence of graft loss in humoral rejection group was 27.4 %, significantly higher than 7.3 % in cellular rejection group and 2.2 % in normal group, P＜0. 001. Kaplan-Meier analysis revealed the survival rate of grafts in humoral rejection group was significantly lower than in cellular rejection group and normal group (P＜0.001 ). After patients with irreversible rejection were excluded,there was no significant difference in the survival rate of grafts among the three groups.Conclusion Patients with acute humoral rejection survived with inferior graft outcome,but completely reversible rejection showed no effect on the graft survival.

Objective To investigate the dynamical changes of Rho kinase in the cerebrospinal fluid (CSF) and its relationship with cerebral vascular spasm CVS. Methods CSF were collected on the ist, 3rd, 7th, 10th and 14th day after subarachnoid hemorrhage. The expression of Rho-kinase mRNA in CSF was determined by RT-PCR. The expression of endothelin-1 in CSF was determined by radioimmuno-assay. TCD was used to measure the velocity of the cerebral artery. Results The levels of ET-1 and Rho-kinase mRNA in CSF were re-markably increased on the 3rd day, and reached at the peak on the 7th day after subarachnoid hemorrhage, which were significantly higher than those without CVS. Conclusion There is a positive correlation between the level of Rho-kinase mRNA and ET-1 in CSF. Rho-kinase may participate in the development of CVS.
