Objective To evaluate the clinical value of two-hour post-dose cyclosporine (CsA) level (C 2) monitoring in renal transplantation (RTx) recipients with functional renal allograft more than one year.Methods 126 RTx recipients with functional renal allograft more than one year treated with CsA-microemulsion-based triple therapy immunosuppression were enrolled. Whole blood samples were collected 2?h after CsA administration and the CsA level was measured by fluorescence polarization immunoassay (TDx).Results C 2 levels at 3 month and 1 year following RTx were 0.830 ? 0.307 ??mol/L and 0.678 ? 0.306 ??mol/L respectively, average C 2 level between 1 to 5 years was 0.609 ? 0.195 ??mol/L,and after 5 and 10 years, C 2 levels decreased to 0.546 ? 0.163 ??mol/L and 0.547 ? 0.227 ??mol/L respectively. Adequate C 2 level in the first 5 years after RTx was correlated with improved allograft renal function and there was a significant relationship between C 2 level and CsA dose. Variation of C 2 level became greater in long-term survival RTx recipients.Conclusion In long term maintenance phase of RTx recipients, C 2 concentration was also useful in the CsA therapeutic monitoring, but the variation became greater in such patients.

Objective To analyze the impact of allograft category on the result of living related donor kidney transplantation (LRKT)and to evaluate the predominant donors. Methods A retrospective analysis of 104 recipients receiving LRKT from Apr. 2004 to Mar. 2008 was performed. Based on donor resource, all the recipient-donor pairs were divided into four groups: spousal donation group,parental donation group, sibling donation group and cousinly donation group. The observational parameters were selected for analysis, such as average post-transplant hospitalization dates, time for serum creatinine (Scr) back to normal level, Scr levels of every observational time point, incidence of major complications (infection, rejection, DGF) and recipient/graft survival rate. Results Recipient/graft survival rate of sibling donation group seemed higher. Recipients of sibling donation group seemed to have fewer post-transplant hospitalization dates, but higher rates of infection, while those of parental donation group seemed to have higher rates of rejection. Rates of rejection and infection of spousal donation group were lower than supposed. There was no statistically significant difference in time for Scr back to normal level and Set levels of every observational time point among these four groups. Conclusions The result of sibling donor renal transplantation is better, while short-term outcome of spouse donor renal transplantation is ideal, which is similar with parent or cousin donor renal transplantation. Except for human leukocyte antigen, aspects such as quality of donor kidney, predominance during operation and self-administration post-transplant are also the guarantee for the success.

BACKGROUND:Studies have shown that polyethylene polymer-synthesized ureteral stents have good biocompatibility in vivo, but the side effects are found to induce the body to produce inflammatory, pyrogenic, and al ergic reactions. Therefore, studies have mainly aimed to explore the biocompatibility, toxic and side effects, inflammation of newly developed ureteral stents synthesized by L-lactic acid, glycolide, and barium sulfate. OBJECTIVE:Based on the biocompatibility comparisons on cel toxicity test, inflammatory reaction, al ergic reaction, pyrogen reaction and mortality after implantation between the usage of polyethylene material and L-lactic acid, glycolide, barium sulphate syntheses, to provide a better reference to introduce a new clinical ureteral stent material. METHODS:There were three groups in the experiment:blank control group, new material group, polyethylene group. Cel s were cultured in normal medium, leach liquid of L-lactic acid, glycolide, barium sulphate syntheses and leach liquid of polyethylene, respectively. RESULTS AND CONCLUSION:The toxic effects were significantly enhanced in the urethral epithelial cel s that grew in the leach liquids of two materials compared with the blank control group (P<0.05), but the two kinds of materials had no significant statistical difference in the toxicity test (P>0.05). Hematoxylin-eosin staining results showed that there were obvious inflammatory infiltrations in muscle tissue and the number of neutrophils and eosinophils were increased when the two kinds of materials were implanted in the rats for 2 and 6 weeks (P<0.05), but the inflammatory infiltration and tissue damage in the new material group was less than that in the polyethylene group (P<0.05). ELISA results showed that the serum concentrations of interleukin-10 and interleukin-23 were significantly increased when the two kinds of materials were implanted in the rats for 6 weeks (P<0.05), but the content of inflammatory cytokines in the new material group was less than that in the polyethylene group (P<0.05). In the new material group, there was only one rat that developed al ergic reaction and there was no pyrogen reaction or death;however, in the polyethylene group, there were three rats with presence of al ergic reaction and one rat with pyrogen reaction but no death. These findings indicate that the new ureteral stent material synthesized with L-lactic acid, glycolide and barium sulphate can reduce inflammation reactions, al ergic reactions and pyrogen reactions to the body, and has better biocompatibility than polyethylene composite material.

Objective To investigate mupiroein resistance in Staphylococcus aureus (SAU) and the resistance to commonly used antibiotics in mupirocin-resistant strains. Methods Four hundred and ninety clinically isolated SAU strains froin January 2005 to May 2007 in the First Affiliated Hospital,Wenzhou Medical College were screened by mupirocin(5μg)disc diffusion method.Minimum inhibition concentration(MIC)and the amplification of mupA gene were performed to determine the resistance to mupirocin.Resistance to cefoxitin,gentamycin, levofloxacin, trimethoprim/sulfamethoxazole, rifampin, erythromycin, clindamycin, tetracycline and vancomycin in mupirocin-resistant strains was detected by disc diffusion method, and the amplification of mecA gene was performed to confirm the methieillin resistance among mupiroein-resistant strains.Results Twenty-seven mupirocin-resistant strains were obtained,in which 22(81.5%)were hish-level mupirocin resistant(MuH)and the rest were low-level mupirocin resistant(MuL).Among 27 mupirocin-resistant strains,24 were methicillin-resistant Staphylococcus aureus (MRSA)in which 21 were MuH and 3 were MuL strains.Drug sensitivity tests showed that the resistance to gentamycin,levofloxacin,trimethoprim/sulfamethoxazole,rifampin,erythromycin,elindamycin and tetracycline were hish among MuH and MuL strains,and most of these strains were multi-drug resistant.All strains were susceptible to vaneomycin.Conclusions Most of the clinical emerged mupirocin-resistant SAU strains are MuH and show hish resistance to commonly used antibiotics.Therefore,detection and drug sensitivity test of mupirocin-resistant strains should be strengthened in clinic practice in order to prevent it from dissemination.

Objective To analyze the relationship between the genetic polymorphisms of organic anion transporting polypeptide (SLCO1B1 and SLCO1B3) and mycophenolic acid ( MPA)pharmacokinetics in Chinese kidney transplant recipients. Methods Gene mutations (SLCO1B3T334G, SLCO1B1 A338G) were detected in 68 recipients by PCR-LDR. The plasma samples were collected and blood concentration of MPA was measured on the 28 th day after transplantation. The area under the curve (AUC)0-12 of MPA in different genotype recipients was compared to analyze the correlation between single nucleotide polymorphisms (SNPs) and MPA pharmacokinetics. Results MPA AUC0-12 was higher in SLCO1B3 T334G GG carriers group than in TT carriers [(54. 54 ±14.40)vs(37.30±12.88)mg·h·L-1,(P=0.052)].However,there was no difference in MPA AUC0-12 among each genotype of SLCO1B1 A338G (P>0. 05). Conclusion Genetic polymorphisms of SLCO1B3 affect interindividual variety in plasma MPA concentration in Chinese kidney transplantation recipients.
