Objective To analyze the reasons and outcomes of the unplanned re-operation in renal transplant recipients during perioperative period,and to summarize the corresponding strategies.Methods From January 2014 to September 2017,the clinical data of 20 cases of kidney transplantation which had a total of 22 unplanned re-operations were retrospectively analyzed.All patients were given quadruple immunosuppression with antibody induction and tacrolimus (TAC) and mycophenolate mofetil (MMF) plus prednisone (Pred).We analyzed the reasons,occurrence time,effect of re-operation and the renal function,as well as survival rate of all graft and recipient.The delayed graft function (DGF),acute rejection (AR) and incidence of pulmonary infection were monitored as well.Results Up to September 2017,during the follow-up of 1-36 months,the overall rate of unplanned re-operation was 4.6％,and 2 patients underwent 3 operations.For the reasons of re-operation,there were 18 cases of bleeding (13 cases of blood oozing from the wound surface,3 cases of renal parenchyma rupture because of rejection,and 2 cases of rupture of renal artery infection),2 cases of renal artery thrombosis and 2 cases of the repair of leakage of urine.Two operations were performed within 1 days for 9 cases,2-5 days for 5 cases,6-10 days for 3 cases,above 10 days for 45 cases.There was no deaths during the perioperative period.One patient died of rupture of exiliac aneurysm 3 months after the operation.One patient died of cerebral hemorrhage 6 months postoperation.The death censored graft survival rate was 72.2％ (13/18) and the incidence of DGF was 55 ％.Conclusion The major reason of unplanned re-operation for renal transplantation is associated with bleeding of various causes.And the incidence of DGF is high.If the secondary operation was performed with the correct decision,the kidney allograft recovers well.

Objective: To explore the diagnosis and treatment of BKV nephropathy after renal transplantation. Methods: A total of 62 patients with progressive creatinine elevation were routinely examined by blood and urine BKV-DNA. And 21 patients with positive results underwent graft biopsies for confirming a diagnosis. Results: Among 21 cases of BKV infection, 20 cases received leflunomide in replacing mycophenolate mofetil (MMF) and a lower dose of tacrolimus. One case with urine (-) & blood (+ ) received sirolimus in replacing tacrolimus and a lower dose of MMF. Among 11 cases with urine (+ ) and blood (-), urinary BKV-DNA turned negative & creatinine decreased markedly (n=4), urinary BKV-DNA load decreased & creatinine stablized (n=4), death from pulmonary infection with hepatic & renal failure (n=1), urine BKV-DNA load decreased & creatine increased (n=1), BKV–DNA load was not re-examined in 1 case of acute rejection and hydronephrosis with elevated creatine; Among 9 cases with urine (+ ) & blood (+ ), blood BKV-DNA turned negative with urinary BKV-DNA load & creatine decreased (n=6), blood BKV-DNA load decreased & creatine stablized (n=2) and no re-examination with a stable level of creatine (n=1); One case with urine (-) & blood (+ ) was not timely treated and ultimately leading to graft loss after an onset of acute rejection. Conclusions BKV nephropathy may be effectively treated by decreasing immunosuppressive intensity. However, clinicians should stay on a high alert for acute rejection due to an excessive reduction of immunosuppressive agents.

Objective To summarzie the experiences of kidney transplantation from rhabdomyolysis.Methods The surgical procedures and treatment protocols of the kidney transplantation in 3 cases from DD donors who suffered from anuria due to rhabdomyolysis were retrospectively analyzed.Results Three recipients were donated by two donors.When the blood of kidneys is washed out,the color of the kidneys was brown,and when the kidneys restored the blood perfusion,the transplanted kidneys were dark brown.All of these 3 cases had delayed renal function,and 2 recipients who received the kidneys from the same donor secreted the urine 3 weeks after surgery.The creatinine gradually decreased,and they discharged when the renal function was normal.The urine volume in the another recipient was 3000 ml or more per day in the first two days,gradually decreased from the third day,until anuria.We conducted an exploration of the transplanted kidney due to the area of transplantation uplift.We found that the kidney was bright red during the operation,the hematoma was removed and hemostasis was done,the urine volume gradually increased from one week after surgery,and the creatinine levels gradually decreased.After two months the creatinine levels were 103μmol/L.Conclusion For the patients with rhabdomyolysis,their kidneys can be transplanted after active preservation,evaluation of the donor kidney function and blood flow,and the short-term outcome is satisfactory.

Objective:To summarize the clinical experiences of managing patients with novel coronavirus(2019-nCoV) infection after kidney transplantation.Methods:Clinical data were retrospectively analyzed for two patients with 2019-nCoV infection after renal transplantation in January 2020. Case 1 was a 48-year-old male with CMV pneumonia secondary to 2019-nCoV infection at 4 months post-transplantation. CT imaging showed multiple patchy ground-glass opacities of both lungs. Case 2 was a 59-year-old male who screened positive for 2019-nCoV nucleic acid due to fever at 9 days post-transplantation and he showed no clinical manifestations of pneumonia. After a definite diagnosis, case 1 was transferred to a designated hospital for isolation. Treatment regimens: cefoperazone sulbactam sodium plus linezolid for anti-infection, gamma globulin for enhancing immunity, methylprednisolone for controlling inflammatory responses and antiviral regimens of arbidol tablets plus lopina-velitonavir tablets. Case 2 was isolated in a single room. The treatment plan included cefoperazone sulbactam sodium for anti-infection, gamma globulin for enhancing immunity, arbidol for antiviral therapy and other symptomatic measures.Results:During a follow-up period of 3 weeks, case 1 recovered with renal dysfunction, nucleic acid test of nasopharyngeal swab turned negative and pulmonary imaging improved. Case 2 showed no obvious clinical symptoms and nucleic acid test of nasopharyngeal swab turned negative thrice.Conclusions:Renal transplant recipients should take precautions to avoid exposure to high-risk environments. A definite diagnosis should be made on the basis of clinical manifestations and results of nucleic acid test and pulmonary imaging. Currently there is no effective antiviral agent and symptomatic treatment is a major option.

Objective:To design and synthesize photosensitizers with different substituents and to identify its physicochemical characteritics and photodynamic effect on tumor cells.Methods:Two kinds of BODIPY photosensitizers BPOI and BPCI were synthesized through condensation reaction between aldehyde and reactive hydrogen of pyrrole,followed with electrophilic substitution reaction.Physicochemical properties were characterized by 1H NMR,FT-IR and UV-visible absorption spectra and fluorescence emission spectra.The ability to produce reactive oxygen species was detected by BPDF and DCFH-DA.Photodynamic therapy effect on rat glioma C6 cells in vitro was determined by MTT method.Results:Two kinds of BODIPY photosensitizers BPOI and BPCI were successfully synthesized with different substituents,which were confirmed by 1H NMR,FT-IR.Both materials had low toxicity and could be readily taken up by tumor cells.The ability of synthesized photosensitizers to produce reactive oxygen species was strongly influenced by solvent polarity when the substituent belongs to electron-donating group,while no effect was found when the substituent belongs to electron-withdrawing group.Conclusion:Photosensitizer BPOI with electron-donating substituent produces reactive oxygen species with a slow rate in a highly polar environment,while the ability to produce reactive oxgen is greatly improved in a low polarity environment,which is expected to be used for environmental-selective photodynamic therapy in tumor cells.

Purpose: The aim of this meta-analysis was to evaluate the efficacy and safety of imidafenacin for overactive bladder (OAB) induced by benign prostatic hyperplasia (BPH) in men receiving alpha-blocker monotherapy. Methods: We performed a systematic research of the PubMed, Embase, and Cochrane Library databases, and searched for studies about alpha-blocker with or without imidafenacin treatment for OAB in patients with BPH. We also investigated the original references of the included texts. Results: Four randomized controlled trials including 779 participants with BPH (389 in the alpha-blocker+imidafenacin group and 390 in the alpha-blocker only group) were studied. The main efficacy endpoint was the Overactive Bladder Symptom Score, which showed a mean difference of -1.88 (95% confidence interval, -2.32 to -1.44; P<0.00001), suggesting that alpha-blocker and imidafenacin treatment was effective in treating men with OAB. As other primary efficacy end points, the International Prostate Symptom Score (IPSS) total score (P=0.47), the IPSS storage symptom score (P=0.07), the IPSS voiding symptom score (P=0.60), and the IPSS quality of life score (P=0.18) indicated that 2 methods had no significant differences in treating men with OAB. In terms of safety, which was assessed using postvoid residual volume (P=0.05) and maximum flow rate (P=0.53), the analysis suggested that combination treatment was very well tolerated. Conclusions This study suggested that imidafenacin plus alpha-blocker was an efficacious and safe treatment for OAB symptoms in BPH patients.

Purpose: Transcutaneous electrical neural stimulation (TENS), as a non-invasive modality, has been clinically used as an alternative treatment for children with overactive bladder (OAB). We conducted a pooled analysis to explore the effect of TENS on OAB. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-analysis guideline was followed in this study. The MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases, as well as the reference lists of the retrieved studies, were used to find trials relevant for assessing the use of TENS to treat OAB. Results: Of the 246 records identified, 8 publications were analyzed in our study. Our analysis found that TENS resulted in a greater decrease of wet days/wk, daily voiding frequency, daily incontinence episodes, and daily number of voids than was observed in the control group. Furthermore, TENS-treated patients showed similar visual analogue scale (VAS) scores to patients in the control group, demonstrating that the application of TENS did not increase patients’ discomfort and pain. TENS had a relative advantage in the number of partial responses, but no clear differences were found in frequency of no response or a full response compared to the control group. In urodynamic testing, TENS led to obvious improvements in average voided volume and maximum voided volume in children with OAB. Conclusions TENS had a remarkable effect on the improvement of urodynamic indexes and objective OAB symptoms without a significant increase in VAS scores for children with OAB.
